FIELD OF THE INVENTION
[0001] The present invention relates to a fixing section for an oral hygiene device, a cable section for an oral hygiene device and an oral hygiene device. BACKGROUND OF THE INVENTION
[0002] It is known that electrical oral hygiene devices, in particular electric toothbrushes, can have separably mounted replacement fasteners, such as an electric toothbrush replacement brush head. It is also known that the coupling between the fixation and a cable of the oral hygiene device can be carried out by mechanical means such as a pressure fitting provided in the fixture which fits by pressure within a groove provided in the cable. Mechanical couplings often have a certain compensation or go between the coupling partners due to tolerances between the coupling partners. Such compensations or openings have the tendency to generate unwanted rattling noise during the operation of the device.
[0003] It is, therefore, a desire to provide an improved coupling between a fixing section and a cable section of an oral hygiene device and, in particular, a fixing section and a cable section, which allow for this improved coupling. SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
[0009] One aspect of the present description concerns a connection, in particular a removable connection, between a securing section and a cable section of a (in particular electrical) oral care device, in which at least one connection (in in particular, a connection established between the movably mounted parts that are activated during operation and are intended to transfer the movement of a motor in the cable section of a functional element, in the clamping section) between the clamping section and the section cable is performed as a magnetic coupling. Mechanical couplings, in general, have gaps or gaps based on the inherently tolerance between the coupling partners, so that the coupling partners can move relatively to each other when the respective connection is established between the parts to be driven during operation . Such a mechanical connection is then prone to generate unwanted noise during operation. A magnetic coupling can inherently be designed with less play so that a magnetic coupling is likely to produce less noise.
[00010] In some embodiments, a fixation section as proposed comprises a first magnetic coupling element, which has at least one permanent magnet or a magnetizable element. The first magnetic coupling is arranged to establish a magnetic connection with a second magnetic coupling element provided on a cable section in a fixed state.
[00011] In some embodiments, a clamping section may additionally comprise a clamping housing, a functional element mounted for the induced movement clamping housing and a movement transmitter. The movement transmitter can, at one end, be coupled to the functional element to transfer movement to the functional element and at the other end it can be equipped with the first magnetic coupling element. The movement transmitter can, in particular, extend into a cavity formed inside the fixing housing. In some embodiments, the functional element may be a working element, such as a brush head for cleaning teeth. In some embodiments, the fixing housing may have a first coupling structure designed to establish an additional connection with a second coupling structure provided in the cable section.
[00012] On the one hand, a magnetizable element (for example, a magnetizable steel or iron element) can be made relatively inexpensively, and a fixing section intended for disposal after some time of use can then be made relatively inexpensively. This is particularly interesting in cases where the costs of a permanent magnet would be in the same order as the costs of the entire fixing section. On the other hand, a permanent magnet in the clamping section in conjunction with a permanent magnet in the cable section can provide greater coupling resistance than a combination of permanent magnet and magnetizable element in the same construction volume.
[00013] In some embodiments, the first magnetic coupling element comprises a protective cover that protects the first magnetic coupling element from corrosion or abrasion. In such embodiments, the protective cover can be resistant to abrasion, as, during a typical life cycle of the fixing section, the protective cover remains intact. As an oral hygiene device is used in a humid environment and, typically, with abrasive and / or corrosive chemicals, such as mouthwashes or toothpaste, a thin coating, such as a 10-inch gold coating thick micrometers can be worn in a very short period. A protective cover made of about 20 μm thick, or more, optionally about 30 μm or more, yet optionally 40 μm or more, even more, optionally, about 50 μm or more of the metal layer, layer ceramic, glass layer or plastic layer or abrasion resistant resin can be used. In some embodiments, the protective cover may be 60 μm or more thick, 70 μm or more, 80 μm or more, 90 μm or more, 100 μm or more, 150 μm or more or 200 μm or more, and / or any thickness within or including the values provided above or any ranges, including or within the values provided above. In some embodiments, the protective cover is made as an element essentially in the shape of a bowl that can be mounted by gluing, press fitting, crimping, shrink fitting, stamping, welding, pressure fitting or any combination thereof. The protective cover is, in some particular embodiments, made as a plate or disc that can be glued to the magnetic coupling element. In some embodiments, a protective cap is used which is manufactured in a process of deep drawing, drawing by puncture or thermoforming.
[00014] In general, the protective cover can be designed to be resistant to abrasion, for a temporary period that corresponds to a typical period of use of the fastening section. The typical period of use can be about three months, with three activation periods of two to four minutes a day, therefore, the period of use operation can be about 540 minutes to about 1,080 minutes. However, the protective cover can be designed to be resistant to abrasion for longer or shorter periods of time. In particular, in some embodiments, a protective cap can be used which is resistant to abrasion for much longer than 1,080 minutes, for example 2,000 minutes, 4,000 minutes, 10,000 minutes or even longer.
[00015] In some embodiments, the first magnetic coupling element is at least partially accommodated in a recess or cavity provided in the motion transmitter. In some embodiments, the motion transmitter may comprise a support element, in which the first magnetic coupling element is at least partially accommodated. In some embodiments, the motion transmitter may comprise a rod element, in particular a rod element made of metal, such as stainless steel. Such a metal rod is likely to provide stability not provided by a motion transmitter that is entirely made of a plastic material. The rod element may, in some embodiments, be pivoted to the functional element, in particular to a mounting location, which is displaced from an axis around which the functional element will be driven during operation. Alternatively or additionally, the rod element can be mounted on the pivot of a support element, for example a support element as mentioned above, which has a recess that has at least partially accommodated the first magnetic coupling element. The pivot assembly of the stem element is capable of withstanding the relative movement between the stem element and the functional element or the supporting element, respectively.
[00016] In some embodiments, the securing section, the protective cover, the first magnetic coupling element and / or the motion transmitter have a centralizing structure that is designed to support the centralization of at least the first magnetic coupling element with the second magnetic coupling element, during a clamping process.
[00017] In some embodiments, the first magnetic coupling element may have at least one indentation or recess, which is filled with plastic material, in particular with injection molded plastic material. For example, the support element mentioned above can be made in a plastic injection molding step with the first magnetic coupling element being an insert element. Then, a manufacturing step, for example by snapping the first magnetic coupling element onto a support element, can be discarded with, and the injection molding step can lead to less gaps or gaps between the first element magnetic coupling and the support element, then, in the case of a later assembly of these two parts.
[00018] In one embodiment, the securing section is arranged in such a way that the motion transmitter is mounted free of any return force elements that could influence the behavior of a resonant unit provided in the cable section with an additional spring. Since the springs typically have tolerances, a spring in the clamping section that is intended for coupling with a drive shaft of a resonant unit in a cable section could contribute to the mass-spring system that determines the resonant frequency of the resonant unit . In addition, a spring in the clamping section can also produce additional operating noise due to the tolerance required for mounting the spring.
[00019] In some embodiments, a cable section for connection, the removable connection, optionally with a fixing section as proposed above comprises a second magnetic coupling element arranged on a drive shaft, the second magnetic coupling element of which is arranged for the establishment of a magnetic connection with a first magnetic coupling element provided in the fixing section and a second coupling structure for the establishment of a connection, in particular a mechanical connection (for example, a snap-in or a snap-in connection shape) with a first coupling structure provided in the clamping section, in particular in the clamping housing. The second magnetic coupling element can comprise at least one permanent magnet or a magnetizable element.
[00020] In at least some embodiments, a cable section as proposed comprises a linear drive (ie, a resonant unit that provides a linear reciprocal movement or a DC motor that has a gear for converting a rotary motion into a linear oscillatory movement) to drive the drive shaft in a linear swing, in a longitudinal direction (usually parallel to a longitudinal axis of the drive shaft or coinciding with a longitudinal axis of the drive shaft). In some embodiments, the linear drive can provide a linear oscillatory range of motion through the drive axis in the range of about ± 0.1 mm to about ± 2.0 mm, in particular in an arrangement between about ± 0.5 mm to about ± 1.5 mm, optionally, in a range of between about ± 0.75 mm and about ± 1.25 mm, still optionally, in a range of about ± 0.9 mm mm and about ± 1.1 mm and even more optionally, a linear oscillatory range of motion of about ± 1.0 mm. In some embodiments, the clamping section comprises a set of gears that converts the linear movement provided by the drive shaft and transferred to the movement transmitter in an oscillatory rotation having a maximum angular deflection in a range of ± 5 degrees of ± 40 degrees, in particular in a range of about ± 10 degrees ± 30 degrees, optionally, in a range of about ± 15 degrees and about ± 25 degrees, and optionally, of about ± 20 degrees (in that angular deflection is measured in a state discharged from the functional element). The. longitudinal axis, as referred to in all modalities, generally extends along a longitudinal dimension or the length of the drive shaft or is parallel to a longitudinal axis of the drive shaft or coincides with a longitudinal axis of the drive shaft . The drive shaft means the drive shaft of the motor or its extensions.
[00021] In one embodiment, the second magnetic coupling element may have a protective cover that protects the second magnetic coupling element from corrosion. The protective cover can be resistant to abrasion, as, during a typical life cycle, the cable section of the protective cover remains intact. To the extent that an oral hygiene device is used in a humid environment and typically with abrasive and / or corrosive chemicals, such as mouthwashes or toothpaste, a thin coating or a 10 micrometer thick tin coating can be used. worn out in a very short period. A protective cover made of about 20 μm thick, or more, optionally about 30 μm or more, yet optionally 40 μm or more, even more, optionally, about 50 μm or more of the metal layer, layer ceramic, glass layer or plastic layer or abrasion resistant resin can be better used. In some embodiments, the protective cover may be 60 μm or more thick, 70 μm or more, 80 μm or more, 90 μm or more, 100 μm or more, 150 μm or more or 200 μm or more and / or any thickness within or including the values provided above or any ranges, including or within the values provided above. The protective cover can be made as an element essentially in the shape of a bowl that can be assembled by gluing, press fitting, crimping, shrink fitting, stamping, welding, pressure fitting or any combination thereof. The protective cover is, in a particular embodiment, realized as a plate or disc that can be glued to the magnetic coupling element. The protective cover for the second magnetic coupling can be configured similarly to the protective cover described so far with respect to the first magnetic coupling.
[00022] In one embodiment, the second magnetic coupling element is at least partially accommodated in a recess provided in the drive shaft. In one embodiment, the cable section, the protective cover, the second magnetic coupling element and / or the drive shaft may have a centralizing structure that is designed to support the centralization of at least the first magnetic coupling element with the second magnetic coupling element, during a fixing process.
[00023] In some embodiments, an oral hygiene device may comprise at least one securing section, as proposed, and may further include a cable section that has a second magnetic coupling element and a second coupling structure for establishing a connection to the first coupling structure provided in the securing section. In some embodiments, an oral hygiene device may comprise at least one fixation section as proposed and even a cable section according to a cable section, as proposed in the previous paragraph above. In some embodiments, the cable section comprises a unit that has a drive shaft that is arranged to provide a linear oscillating movement, during operation and the contact faces of the magnetic coupling elements are arranged essentially perpendicular to the direction of linear movement
[00024] In some embodiments, as will be explained in more detail below, the magnetic coupling between the first and the second magnetic coupling elements is designed to, at least partially, disengage if a pulling force is applied to the connection magnetic field that is beyond a limit force. This, at least partial, decoupling of the magnetic coupling partners is then liable to interrupt the transfer of motion and generate noise, which can be observed by a user, who is then informed of a very high load.
[00025] As an example, in case the implement of oral hygiene is an electric toothbrush and the fixation is a replaceable brush head having as a functional element a bristle holder mounted for oscillatory rotation, a magnetic coupling between a motor in a cable section of the oral care device and a motion transmitter in the clamping section must be in a coupled state for the typical pulling forces that occur during operation (ie brushing teeth in an exemplary case). Typical traction forces, which occur during brushing between the first and second magnetic coupling elements, can be generated, in particular due to friction between the treatment elements (eg, bristles) mounted on the support and soft tissue or hard in the oral cavity (for example, teeth or gums). This friction increases with the pressure force with which the functional element (for example, the brush head) is applied on soft or hard tissue (for example, the teeth). Typical pressure force values applied may depend on a range between about 1.5 Newton (N) and about 3.5 N (pressure forces below this range are typically either unused or do not lead to a treatment result pressure values above this range can potentially lead to discomfort and even injury), particularly in a range between about 2 N and 3 N. For the above oscillatory rotating brush heads, it was found that the The tension acting on the magnetic coupling can then be above 5 N and, in particular, above 6 N and, more particularly, in the range between about 6.5 N to about 8.0 N. Greater tensile forces can then be due to a very high pressure force applied by the user or due to the bristles being stuck between the teeth. In both cases, it may be reasonable for the magnetic coupling to be willing to disengage at a pulling force above the permitted pulling force that occurs and maximally. Firstly, the indication to the user that a very high pressure force is applied to the extent that the decoupling can be perceived by the user can be sustained. Second, such an uncoupling is likely to reduce the pain that can occur if the trapped bristles are pulled between the teeth when the magnetic coupling can overcome the higher tensile forces. In both cases, decoupling is likely to lead to improved protection of soft and hard tissues against abrasion and other types of damage. In this way, a limit force can be adjusted to 5 N, 5.5 N, 6 N, 6.5 N, 7 N, 7.5 N, 8 N, 8.5 N, 9 N, 9, 5 N , or 10 N, where, in particular, the limit force can be set to a value of at least 6.5 N, optionally, at least 7 N, still, optionally, at least 7.5 N and even more, optionally , at least 8 N. As will be seen later, the limit force can, in particular, be defined by the design of the magnetic coupling, for example by choosing the dimensions of the first and second magnetic coupling elements, choosing the respective materials from which the first and second coupling elements are made, or choosing a gap between the first and second magnetic coupling elements.
[00026] Although it is proposed here to design the magnetic coupling in such a way that the magnetic coupling decouples in the event that a pulling force is applied above a limit force, the example above was experimentally derived for bristle supports mounted for oscillating rotation induced in the fixation housing. While it cannot be excluded that other functional elements can result in the same limit force, another value of limit force can be found as preferred based on experimental research with other functional elements or for another intended oral hygiene application, for example cleaning tongue or gum massage.
[00027] In some embodiments, the securing section has a first magnetic coupling element, which comprises a magnetizable element that can, in particular, be made of stainless steel, so that the additional protective cover can be discarded, whose magnetizable element is fits inside a cylinder at least about 4.5 mm in diameter and at least about 4.5 mm in length. Optionally, the diameter can be at least about 5.0 mm, yet optionally at least about 5.5 mm. Optionally, the length can be at least about 5.5 mm, yet, optionally at least about 6.5 mm.
[00028] In some embodiments, the cable section has a second magnetic coupling element, which comprises a permanent magnet, in particular made of NdFeB, whose permanent magnet fits inside a cylinder of at least about 4.5 mm in diameter. diameter and at least about 4.5 mm in length. Optionally, the diameter can be at least about 5.0 mm, yet optionally at least about 5.5 mm. Optionally, the length can be at least about 5.0 mm, yet optionally at least about 5.5 mm.
[00029] In some embodiments, the movement transmitter is connected in a non-separable way with the fixing section, in particular with a functional element mounted for the induced movement.
[00030] In the following, a detailed description of several examples of modalities will be presented. It should be noted that all features described in the present description, whether they are presented in the previous description of more general modalities or in the following description of the example modalities, although they can be described in the context of a specific modality, are obviously presented as individual characteristics which can be combined with all other features presented, as long as this does not contradict the essence and scope of the present description. In particular, all of the features described in either the first or second magnetic coupling element can also be applied to the other.
[00031] Figure 1 is a perspective representation of an example of an oral hygiene device modality 1, performed here as an electric toothbrush. The oral hygiene device 1 comprises a cable section 200 and a fixation section 100. Here, the fixation section 100 is realized as a removable brush section. The clamping section 100 has a functional element 130, here realized as a brush head, whose functional element 130 is movably mounted in a clamping housing 150 so that the functional element 130 can be placed in oscillatory rotation (as shown with the double arrow 21) around an axis of rotation R that can be perpendicular to the longitudinal axis L of the fixing section 100. Instead of being performed as an electric toothbrush, the oral hygiene device can be performed as a tongue scraper (electric), a wire device (electric), an interdental cleaner (electric) etc. The clamping section can then then be performed as a tongue scraper section, a wire section, an interdental cleaning section, etc. The functional element can be made according to the tongue scraper head, a wire head, an interdental cleaning head etc.
[00032] Figure 2 is a section in lateral cross section through the fastening section 100 taken along a longitudinal axis of the fastening section 100. The fastening section 100 comprises the fastening housing 150 and the functional element 130, which it is movably fixed to the fixing housing 150. a. Functional element 130 can comprise a support element 131 in which a plurality of cleaning elements 133 can be mounted for cleaning and massaging parts of the oral cavity, such as teeth and gums. The support element 131 can be mounted in the clamping housing 150, using a mounting axis 132 for oscillatory rotation induced around an axis of rotation R which can be essentially perpendicular to the longitudinal axis (reference number L, in Figure 1 ) of the fastening section 100.
[00033] The securing section 100 may further comprise a motion transmitter 110 disposed within a cavity 159 formed within the securing housing 150. The motion transmitter 110 can be operated connected to functional element 130, as will be explained in more detail. detail with reference to Figure 3. Generally and applicable to all modalities, "connected operation", must mean a connection that is not intended to be disconnected and that must allow the movement transmitted through the movement transmitter to be transferred to the functional element . The movement transmitter 110 is arranged for transmitting a linear oscillatory movement of the functional element 130, whose linear oscillatory movement can generally be parallel to the longitudinal axis of the clamping section 100 (as indicated by the double arrow D). Such linear oscillatory movement can be provided by a drive shaft of a cable section, when the fastening section 100 is in a fixed state, as will be explained in more detail with reference to Figure 5. a. Motion transmitter 110 may comprise a recess 112 made as a blind hole provided at a first end 110A which is proximal to the opening of cavity 159, the opening of which at the end of connecting section 100 (i.e., the first end 110A of transmitter motion 110 is distal to functional element 130). A first magnetic coupling element 120 is arranged in recess 112. Generally and, as mentioned above for all the features described, applicable to all modalities, the first magnetic coupling element 120 can be realized as a permanent magnet or a magnetizable element, like a block of iron or magnetizable steel. Typically, austenitic steels are not magnetizable, while martensitic or ferritic steel is typically magnetized. The first magnetic coupling element 120 has a coupling side 121 which is oriented towards the opening provided at the distal end of the clamping section 100. Generally and applicable to all modes, the coupling side 121 can be retracted from the opening at the end of the fixture housing for coupling with a cable section, so that the magnetic connection is established in a longitudinal position inside the fixture housing, in particular where this longitudinal location is retracted by a value in the range between about 0.5 cm to about 5.0 cm, for example 1.0 cm, 1.5 cm, 2.0 cm 2.5 cm, 3.0 cm and 3.5 cm, 4.0 cm, 4.5 cm, or any other value located in the mentioned range from the end of the fixing housing and the length of the fixing housing can be in the range from about 3.0 cm to about 10.0 cm. B. first magnetic coupling element 120 can be attached to the motion transmitter 110 in any suitable manner. For example, the first magnetic coupling element 120 can be glued to the motion transmitter 110, it can be snapped into a recess, it can be attached by injection molding to at least part of the motion transmitter over the same or the same can be fixed by other means, as will be explained later.
[00034] In some examples of embodiments, the first magnetic coupling element is realized as an element of iron or magnetized steel. In case the first magnetic coupling element is made of a corrosive material, such as iron or an NdFeB material (from which relatively strong permanent magnets can be made), at least the coupling side of the first magnetic coupling element may have a protective cover to protect the first magnetic coupling element from corrosion.
[00035] The protective cap can be realized as a coating, a top cap, a cap or a cup, which will be explained in more detail below. Generally and applicable to all modalities, any protective cover applied to a first or second magnetic coupling element can lead to a distance between the first and second magnetic coupling elements in the fixed state and thus a reduction in the coupling force effective between the first and the second magnetic coupling elements, so that a layer thickness of about or less than 0.5 mm, or optionally about less than 0.4 mm, still optionally about , or less than 0.3 mm, even more, optionally, of about or less than 0.2 mm, and even more still, optionally, of about, or less than 0.1 mm per cap can be chosen. In other embodiments, the protective cap may comprise a thickness as described above. In the embodiment shown, the first magnetic coupling element 120 is glued to the interior of the recess. This may have an anti-corrosion coating applied to the coupling side 121 or a protective cover that can be glued to the coupling side 121. In the embodiment shown, it would be sufficient to attach a disk-shaped protective cover to the coupling side 121 of the first coupling element. magnetic coupling 120 since the other sides of the first magnetic coupling element 120 are protected by the material surrounding the motion transmitter 110.
[00036] Generally and applicable to all modalities, the first magnetic coupling element 120 can be realized as a cylindrical element that has its cylinder axis essentially oriented parallel to the longitudinal axis of the fixing section 100, where the diameter of the cylinder can be chosen to be about, or greater than 2 mm, optionally, about, or greater than 3 mm, still, optionally about, or greater than 4 mm, even more, optionally, about, or greater than 5 mm, and even more optionally, about, or greater than 6 mm, and / or to any number or range including or within the given values. The. cylindrical shaped element can have any suitable height. In the example of the modality, the height can be chosen to be about, or greater than 2 mm, optionally, as about, or greater than 3 mm, still, optionally, about, or greater than 4 mm, even more, optionally about, or greater than 5 mm, and even more optionally about or greater than 6 mm, and / or any number or range, including or within the given values. In some examples of embodiments, the height of the first magnetic coupling element can be chosen as large as the diameter. In other embodiments, the second magnetic coupling element can be designed to have any suitable shape. In such a case, the smallest possible cylinder to which such a first magnetic coupling element fits can have a diameter and a height as mentioned above.
[00037] In some examples of embodiments, the first magnetic coupling 120 is realized as a permanent magnet. In a case where the securing section 100 is a disposable securing section intended for securable securing to a cable section 200 of an oral care device, material costs can be considered as an important aspect. The realization of the first magnetic coupling element 120 and the second magnetic coupling element as permanent magnets can lead to a relatively high coupling force, while the realization of the first magnetic coupling element 120 as a magnetizable element, such as an iron element or steel reduces the material costs of fastening section 100.
[00038] The clamping section 100, as shown in Figure 2, may further comprise an insert element 151 which is snapped into the clamping housing 150, thus forming part of the clamping housing 150. The insert element 151 can be equipped with a first coupling structure 152 designed to establish an additional coupling (that is, a coupling other than the magnetic coupling that will be established on the first magnetic coupling element 120) with a cable section of an oral hygiene device in a fixed state. In the example embodiment shown, the first coupling structure 152 is made by mechanical coupling means such as snap-fit hooks or spring elements to clamp the projections provided in the cable section. In other examples of embodiments, the first coupling structure 152 can be realized by an additional magnetic coupling element. The longitudinal positions where the magnetic connection is established and where the additional connection (for example, mechanical connection) is established can be separated, in particular by a distance that is in the range of about 0.5 cm to about 3.0 cm.
[00039] Figure 3 is a section in longitudinal, transverse cross section, through the example of the fixation section shown in Figure 2, where the observation direction is in relation to the cleaning elements. As can be seen from Figure 3, the motion transmitter 110 is coupled to the functional element by a coupling pin 111 provided at a second end 110B of the motion transmitter 110. Coupling pin 111 establishes a coupling with a section of coupling 134 provided in the support element 131, in a position that is eccentric in relation to the axis of rotation defined by the mounting axis 132. When the movement transmitter 110 is set in linear oscillatory movement, as indicated by the double arrow A, then the support member 131 will be put in oscillatory rotation about the axis of rotation. As will also be explained later, in some embodiments, the movement transmitter 110 is not associated with any return force element, such as a bending spring that could influence the movement transmitter in a defined resting position, whenever the motion transmitter is not being triggered.
[00040] Figure 4 shows a longitudinal section through a schematic cable section 200. In the example embodiment shown, the cable section 200 comprises a drive shaft 210, which functions as a part of the moving motor of a resonant linear drive. 260, whose linear drive 260 is arranged inside the cable housing 250. During operation, linear drive 260 provides linear oscillatory movement of the drive rod 210, as indicated by the double arrow B. In the example shown, the axis drive element 210 can be extended by an extension element 219, thereby forming a part of the drive shaft 210. The extension element 219 can provide an increase in diameter in relation to the diameter of the drive shaft 210. A recess 211 can be provided in the extension element 219 to accommodate a second magnetic coupling element 220. Instead of being accommodated in the extension element 219, the second magnetic coupling element device 220 can, of course, be directly attached to the drive shaft 210 or the drive shaft can be made, at least in its tip portion, from a permanent magnetic material, the tip of which can then form the second coupling element magnetic 220. The second magnetic coupling element 220 has a coupling side 221 intended to contact the respective coupling side 121 (shown in Figure 2) of the first magnetic coupling element 120 (shown in Figure 2) of the fixation when being fixed. The coupling side of the first magnetic coupling element and the coupling side of the second magnetic coupling element can be flat or they can be at least partially negative to each other.
[00041] Generally and applicable to all modalities, the second magnetic coupling element 220 can be realized as a cylindrical element having its cylinder axis essentially oriented parallel to the longitudinal axis of the drive axis, where the diameter of the cylinder can be chosen to be about, or greater than 2 mm, optionally, about, or greater than 3 mm, still optionally about, or greater than 4 mm, even more, optionally, about, or greater than 5 mm , and even more optionally about, or greater than 6 mm or any individual number within or any ranges including or within the given values. Any suitable height of the cylindrical element can be chosen. Any suitable height of the cylindrical element can be chosen. For example, the height can be chosen to be about, or greater than 2 mm, optionally, about, or greater than 3 mm, yet, optionally, about, or greater than 4 mm, even more, optionally, about of or greater than 5 mm, and even more, optionally, about or greater than 6 mm. In some examples of modalities, the height can be chosen as large as the diameter. In other embodiments, the second magnetic coupling element can be designed to have any suitable shape. In such a case, the smallest possible cylinder to which such a second magnetic coupling element fits may have a diameter and a height as noted above.
[00042] Generally, the cable section comprises a cable housing in which a second coupling structure designed to establish a connection with the first coupling structure provided in the fastening section is made. In the example embodiment shown, cable section 200 has a cable housing 250 comprising an upper cable housing section 250A intended for coupling with the clamping section and a lower cable housing section 250B intended to be gripped by hand of a user. Here, the upper cable housing section 250A comprises an upper part 251 in which a second coupling structure 252 can be made, the second coupling structure 252 can form an additional connection, with the first coupling structure 152 (shown in Figure 2) the fixing section.
[00043] In some embodiments, the second coupling structure 252 and the first coupling structure may establish a coupling that is different from the connection established by the first magnetic coupling and the second magnetic coupling or coupling may be similar. For example, the coupling established by the first coupling structure and the second coupling structure can comprise a mechanical lock, magnetic lock, or the like, or combinations thereof. In some embodiments having an upper housing section 250A and a lower housing section 250B, the upper housing section 250A may be arranged for induced movement, for example the upper housing section 250A may perform an oscillatory rotation about the axis longitudinal, a longitudinal linear vibration, and / or an alternate linear reciprocation along a direction that is generally parallel to a longitudinal axis of the transmission shaft during operation. In such embodiments, the clamping housing, which is coupled to the upper housing section 250A, performs a first movement during operation, for example rotation around the longitudinal axis, longitudinal linear vibration, and / or linear reciprocating, while the movement transmitter can trigger the functional element for a second movement. The first and second movements are described further in relation to Figure 5. In some embodiments, the upper housing section 250A is not triggered and remains stationary in relation to the lower housing section 250B.
[00044] Figure 5 shows a section in longitudinal cross section of a fixing section 100 and an upper housing section of a cable section 200 in a fixed state. It is shown that the first and second magnetic coupling elements 120 and 220 have an established magnetic connection, which couples the drive shaft 210 of the cable section 200 with the movement transmitter 110 of the clamping section 100 so that during the operation, a linear reciprocation of the drive shaft 210, as indicated by the double arrow B, will be transferred to the functional element 130, through the movement transmitter 110. In some embodiments, as the transmitted movement is a linear reciprocation, the magnetic coupling it does not need to transmit a rotational movement, so that flat coupling sides of the first and second magnetic coupling elements are suitable.
[00045] In addition, the first and second coupling structures 152 and 252 have a second connection established between the clamping housing 150 and the cable housing 250 so that the clamping section 100 is fixed in relation to the housing cable 250. For those modalities in which the upper housing section is activated in an oscillatory rotation about the longitudinal axis, a longitudinal linear vibration, and / or a linear reciprocation along a direction that is generally parallel to a longitudinal axis of the cable 200, the movement of the upper housing section is transmitted to the fixing housing through the connection provided between the first and second coupling structures 152 and 252.
[00046] As mentioned before, the movement transmitter 110 can be mounted free of any element of return force. It is known to use a return force element for a motion transmitter provided in a clamping section in the case of a mechanical connection being established between the motion transmitter and the drive shaft, as, then, essentially, the Coupling force must first be overcome during the clamping process. Without a return force element, the motion transmitter would potentially be pushed away in the clamping process and the mechanical coupling cannot become easily established. For the described magnetic coupling, the first and second magnetic coupling elements will attract each other when the clamping section is attached to the cable section and the motion transmitter will then be moved towards the drive axis so that the magnetic coupling is established without the need to first overcome any resistance. In particular, for a cable section it comprises a resonant unit, in which the resonance frequency is dependent on the mass-spring system, including a return force element, such as a spring acting on the motion transmitter, the tolerances on the spring would lead to variations in the resonant frequency of the resonant unit for different fixations. In addition, the disposal of a return force element bears an efficient manufacturing cost.
[00047] Generally and applicable to all modalities, the first and second magnetic coupling elements 120 and 220 can each be realized as a permanent magnet or permanent magnet arrangement or as a magnetizable element, such as an element iron or steel, or an arrangement of such elements. Any type of permanent magnet material can be used, for example the high energy SmCo or NdFeB materials, either made as sintered elements or elements bonded to plastic, or any hard ferrite could be used as sintered strontium ferrite. Permanent magnetic elements attached to plastic tend to have a relatively lower magnetic flux density when compared to, for example, sintered permanent magnets. Sintered NdFeB magnets have a relatively high magnetic flux density, but are also relatively expensive and are susceptible to corrosion. Hard ferrite magnets are relatively inexpensive and as ceramic materials they are less prone to corrosion, but have only a limited magnetic flux density. In the event that one of the first or second magnetic coupling element is realized as a magnetizable element, the other of the first or second magnetic coupling element is to be realized as a permanent magnet or a permanent magnet arrangement. Permanent magnets are widely available, for example from IBS Magnet, Berlin, Germany.
[00048] In some embodiments, at least one of the first or second magnetic coupling element is made of, or consists, at least partially, of the NdFeB material, in particular the sintered NdFeB material. In some of these embodiments, the second magnetic coupling element provided in the cable section is made of, or consists, at least partially, of the sintered NdFeB material. The latter allows the realization of the first magnetic coupling element, as a relatively inexpensive magnetizable element, as an iron or steel element or by an arrangement of such elements.
[00049] Permanent magnets prone to corrosion like sintered NdFeB magnets can typically be available from a supplier with a thin anti-corrosion coating, such as a tin or nickel coating. Unfortunately, toothpaste can abrasion these standard coatings very quickly during operation. Thus, it may then be necessary to equip these permanent magnets with a low abrasion and anti-corrosion cap to overcome conditions during the operation of an oral hygiene device. Various materials can be chosen for the lid, such as low abrasiveness plastic materials (for example, to make a deep-drawn plastic cup), ceramics, metal sheets, glass, etc.
[00050] Some permanent magnet materials, such as NdFeB have an operating temperature as low as 60 degrees Celsius, whose operating temperature is also dependent on the particular dimensions of the permanent magnet. For these permanent magnets, corrosion protection cannot be applied by a plastic injection process, during which temperatures of 200 degrees Celsius and higher can occur when the permanent magnet can then lose its magnetization. The protective cover can be applied by casting (for example, a resin), gluing (for example, a metal, ceramic, glass or disc), pressure fitting, welding, etc., as already mentioned. The. Magnetic coupling created by the first and second coupling elements must overcome a typical tensile force applied to the functional element, as explained above, so that the magnetic coupling is not separated when a force is applied. In the modality example, a typical tensile force applied to the functional element can be up to 10 Newtons, that is, the magnetic coupling must overcome an upward pulling force to a limit value of about 10 Newtons, optionally up to about 9 Newtons, still optionally up to about 8 Newtons, even more optionally up to about 7 Newtons, even more, optionally, up to about 6 Newtons, even more optionally, up to about 5 Newtons, and even more optionally, up to about 4 Newtons or any value within or including the values provided.
[00051] Figures 6A to 6D show four examples of different configurations from S1 to S4 of the first and second magnetic coupling elements. Figure 7 shows the results of the simulation for the effective force that exists between the coupling partners in the coupled state, where the results are shown for various values of a gap between the first and the second magnetic coupling elements, whose gap reflects a cover protective cover on one or both magnetic coupling elements.
[00052] Figure 6A shows a first S1 configuration of a first magnetic coupling element 410A being a cylindrical permanent magnet of NdFeB and a second magnetic coupling element 420A being a stainless steel cylinder. The diameter d1 of the permanent magnet of NdFeB 410A was set to 5 mm in the simulations and the height h1 was set to 5 mm. The diameter d2 of the stainless steel element was set to 5 mm and its height h2 was set to 4.5 mm. An arrow 419A indicates the direction of magnetization of the permanent magnet that has been defined here to be along the longitudinal axis of the cylinder. The total height of the magnetic coupling arrangement is therefore 9.5 mm plus the gap thickness.
[00053] Figure 6B shows a second configuration S2, where the only difference to the first configuration S1 shown in Figure 1 is the direction of magnetization 419B of the first magnetic coupling element 410B which is chosen to be perpendicular to the longitudinal axis of the cylinder.
[00054] Figure 6C shows a third configuration S3 of a first magnetic coupling element 410C and a second magnetic coupling element 420C. The second magnetic coupling element 420C is again assumed to be a stainless steel element, but here, having a height of 3.5 mm. The first 410C magnetic coupling element consists of a permanent NdFeB magnet having a height of 5 mm and a diameter of 3.5 mm. The permanent NdFeB magnet is glued inside an iron cup-shaped container that has an outer diameter of 5 mm and an inner diameter of 4 mm. The iron container consists of a hollow 4104C iron cylinder and a 4103C disc shaped iron back. The 4103C disc-shaped support iron has a diameter of 5 mm and a height of 1.5 mm. The total height of the magnetic coupling system is therefore again 9.5 mm plus the gap thickness. The magnetization direction of the permanent NdFeB magnet 4101C is indicated by the arrow 419C and is assumed to be along the longitudinal axis of the cylinder.
[00055] Figure 6D shows a fourth configuration S4, where the second magnetic coupling element 420D is as in the third configuration S3 of a stainless steel cylinder having a height of 3.5 mm and a diameter of 5 mm. The first magnetic coupling element 410D consists of a first and second permanent semi-cylindrical NdFeB magnets 4101D and 4102D which are magnetized in the opposite direction in the longitudinal direction, as indicated by the magnetizing arrows 4191D and 4192D, respectively. The cylinder formed by two permanent semi-cylindrical NdFeB magnets has a height of 5 mm and a diameter of 5 mm. At the rear, the two permanent semi-cylindrical NdFeB magnets are completed by a support iron 4103D having a disk-like shape, the disk having a height of 1.5 mm and a diameter of 5 mm. Total height is again 9.5 mm plus the thickness of the span.
[00056] In the simulations that were carried out it was assumed that the remainder of the NdFeB permanent magnet material is 1370 mTesla. The properties of stainless steel 1.4021 were calibrated against the measurements.
[00057] Figure 7 shows the results of the simulation for the four configurations of S1, S2, S3, and S4 described above with reference to Figures 6A to 6D. The abscissa indicates the gap between the flat coupling sides of the first and second magnetic coupling elements in millimeters. The span material was assumed to be air. The ordinate indicates the force between the first and the second magnetic coupling elements in the coupled state in Newton. It can be seen that the S4 configuration generally leads to the highest limit force value of the tensile force that the magnetic coupling can withstand, for example the 0.1 mm S4 span configuration leads to a limit force value of about 7.3 Newtons where the first and second magnetic coupling elements disengage. The other configurations lead to a coupling force of about 3.4 to 4.9 Newtons at a span of 0.1 mm.
[00058] Figure 8 is a schematic cross-section through the upper portion of a drive shaft 510 with a second magnetic coupling element 520. In the embodiment shown, the second magnetic coupling element 520 is glued to a protective cover 525 which is generally cup-shaped. The protective cover 525 has one on its upper side, where a first magnetic coupling element 620 indicated by a dashed line can approach the second magnetic coupling element 520, during the fastening process, a centralization structure 526 effected by a protruding edge such that a depression 527 is formed into which the first magnetic coupling element 620 fits. The protruding edge 526 can be tapered in order to approach the first magnetic coupling element 620 to support the centering function. Although the magnetic coupling, as such, already has some self-centralization function, a centralization structure supports the centralization process and can avoid misalignments between the first and the second magnetic coupling elements. As stated before, the first and second magnetic coupling elements can be interchanged with respect to the described features, for example Figure 8 can show an example of a first magnetic coupling element embodiment.
[00059] Here, the protective cover is made by a cup that can fully accommodate the second magnetic coupling element 520 and which extends at least partially over the drive shaft 510. In such an embodiment, the second magnetic coupling element 520 does not it additionally needs to be attached to the drive shaft 510 since the adhesive layer 524 secures the drive shaft 510 and the second magnetic coupling element 520. The thickness d3 of the adhesive layer 524 and the protective cover 525 must be chosen as low as possible to avoid reducing the possible connection force (see Figure 7). As a matter of fact, the 521 coupling side does not need to be glued to the protective cover since the side adhesive layer is sufficient to establish a fixed connection. The thickness d3 could be chosen to be about, or less than 0.2 mm, optionally, to be about, or less than 0.15 mm, yet, optionally, to be about d, or less than 0, 1 mm and even more optionally, of about, or less than 0.05 mm, or any number within and / or any range within or including the values provided. The material of the protective cover can be a plastic material, a ceramic, a glass, or a metal (in particular not magnetizable). In an effort to reduce the thickness of the glue layer 524 and the protective cover, modalities are contemplated where the glue layer exists only on the sides of the drive shaft 510 and the second magnetic coupling element 520, but not between one side coupling 521 of the second magnetic coupling element 520 and a bottom face 531 of the protective cover.
[00060] A protective cover made of magnetizable material could in the example shown in Figure 8 lead to a magnetic short circuit between the magnetic north pole and the magnetic south pole of the permanent magnet and the viable force between the magnetic coupling elements would be reduced.
[00061] Figure 9 is a schematic representation of another embodiment showing the upper portion of a drive shaft 510A, which has a recess 511A that accommodates a second magnetic coupling element 520A. The bending wall portions 512A secure the second magnetic coupling element in the recess 511A. Before introducing the second magnetic coupling element 520A into the recess 511A, the wall portions 512A may have been straight to allow insertion of the second magnetic coupling element 520A into the recess 511A. Then, the wall portions 512A may have been flexed using, for example, a forming pattern, such that the second magnetic coupling element 520A is fixed in the recess. A 525A protective cover can cover the remaining opening, so that the second 520A magnetic coupling element is protected against corrosion. The protective cover 525A can be a resin or any suitable material, as described so far. In the event that the upper portion of the 510A drive shaft is made of a metal (non-magnetizable) or other low abrasive material that can be formed in the stamping process, the protective layer 525A is effectively protected from being worn and thus makes it not necessarily necessary to have high abrasion resistance here.
[00062] Figure 10 is a schematic representation of another embodiment showing the upper portion of a drive shaft 510B and a first magnetic coupling element 620B. The drive shaft 510B has a recess 511B, which accommodates a second magnetic coupling element 520B, whose second magnetic coupling element 520B extends above the drive shaft 510B so that a step-like structure 526B is achieved. A protective cap 525B that can be made as a deep-drawing plastic cup can be glued with a layer of glue 524B over the upper part that extends from the second magnetic coupling element 520B and an upper part of the drive shaft 510B. The first magnetic coupling element 620B may comprise a depression 626B which is adapted to the step-like structure 526B, so that the step-like structure 526B and the depression 626B cooperate to support the centralization of the first and second magnetic coupling elements 620B and 520B in the fixing process. Similar to the embodiment shown in Figure 8, the glue layer 524B may be missing between one side of the coupling 521B and a lower face 531B of the protective cover 525B in an effort to reduce the width of the gap between the first magnetic coupling element and the second magnetic coupling element. For those modalities where the first magnetic coupling comprises a protective cap / cover, similar arrangements can be provided.
[00063] Figure 11 is a schematic representation of the lower portion of a 610C motion transmitter in which a recess 611C is provided, which accommodates a first 620C magnetic coupling element. The 611C recess can be equipped with the 612C snap-fit noses (here made with a 90-degree recess on its rear side) so that the first 620C magnetic coupling element, which has respective depressions, is attached (not separable) on the 610C motion transmitter by mechanical means performed here as snap-fit means. On its front side (side that is closer to the cable than at the rear), the 612C snap-in noses can be tapered in such a way that the first 620C magnetic coupling element can be pushed into position (snap-in by pressure) during manufacture. The motion transmitter can be made as a plastic part, while the first 620B magnetic coupling element can be made as a non-corrosive steel part.
[00064] In other embodiments, the protective cap made as a cup similar to the modality shown can be attached to the drive shaft, for example, by crimping, shrinkage fitting, welding, or pressure fitting.
[00065] Figures 12A, 12B and 12C show several views of another example of a fixation section modality, as proposed. The identical parts have the same reference numbers in these three views. Reference is made after all three Figures 12A, 12B and 12C. Not all numerical references are repeated in all figures.
[00066] A clamping section 700 has a clamping housing 750, a functional element 730 realized as a brush head mounted in the clamping housing 750 for oscillatory rotation induced about an axis of rotation R1, whose axis of rotation R1 is essentially perpendicular to a longitudinal extension direction of the clamping section 700. The clamping section 700 further comprises a motion transmitter 710 that extends into the cavity 759 formed within the clamping housing 750. a. functional element 730 (here: brush head) has a support element 731 on which cleaning elements such as tufts of bristles can be mounted. The support element 731 can comprise a coupling element 731A which, in particular can be an integral part of the support element 731. The support element 731 can be mounted in the fastening housing 750, by means of a fastening element 738 of so that it cannot be easily separated from the 750 mounting housing. b. motion transmitter 710 can comprise a support element 712 and a rod element 716. support element 712 can at least partially accommodate a first magnetic coupling element 720 in a recess 711 at a first end 710A of the motion transmitter 710. The stem element 716 can in particular be made of metal, such as stainless steel, and can optionally be made from a metal wire. A metal rod element can provide greater rigidity and elasticity than a respective part of the motion transmitter made of plastic material. A motion transmitter can be made completely of a single integral part from the plastic material, due to the higher ductility of plastic compared to metal. The stem element 716 can have a first coupling part 716A that is pivoted on the support element 712 and a second coupling part 716B that is pivoted on a coupling section 739 provided in the coupling element 731A of the coupling element support 731. At least one of the first or second coupling part 716A, 716B of the stem element 716 can be a section of the flexed stem that can extend into a hole or blind hole in the support element 712, or of the 731A coupling, respectively. As can be seen particularly in Figure 12C, the first magnetic coupling element 720 may have at least one indentation or groove 729 that is filled with injection molded plastic 714, that is, the first magnetic coupling element 720 may have been molded with overlapping directly with support element 712. This molding step with direct overlap in manufacture leads to minimal gaps or clearances between the first magnetic coupling element 720 and the support element 712. Generally and applicable to all modalities, the first element magnetic coupling can be directly molded with overlap with at least part of the motion transmitter and a depression present in the first magnetic coupling element can be filled with injection molded plastic material so that the first magnetic coupling element is rigidly attached to this injection molded part of the motion transmitter. ç. support member 712 has protrusions 713 that extend in the direction of longitudinal extension at the edge of a contact surface 721 of the first magnetic coupling element 720, the protrusions of which can be radially tapered out such that these protrusions form a centering structure which supports at least the centering of the magnetic connection between the first magnetic coupling element 720 and a second magnetic coupling element in a cable section when fixing the fixing section 700. The centering functionality also acts in a fixed state, when the first and second magnetic coupling elements disengage due to a very high tensile force and the high tensile force disappears as soon as the first and second magnetic coupling elements re-engage due to the magnetic force acting between them. In particular, in cases where one of the first and the second magnetic coupling elements is a magnetizable element, a self-centering force between two permanent magnets is not present and an additional centering structure to center the two coupling partners and thus , optimize the coupling force.
[00067] In some embodiments, the cleaning elements arranged in the fastening section can be made from a soft plastic material, such as rubber or a thermoplastic elastomer (TPE) or it can be made from a more rigid plastic material , such as polyamide (for example, PA 6.12). The cleaning elements can have any type of suitable height, the height of which can be chosen to be between 0.2 mm (for example, for tongue cleaning structures) and 30 mm, where a typical length of a cleaning element can be in the range from about 2.0 mm to about 15.0 mm, optionally between about 5.0 mm and 11.0 mm. The cleaning elements can have any suitable diameter, the diameter of which can be chosen to be in a range of between about 0.2 mm to about 20 mm, optionally, in a range of between about 0.5 mm to about 8.0 mm.
[00068] Additionally, it should be noted that cleaning elements can comprise any suitable cleaning element and / or can comprise elements that are used to massage gums, clean the tongue, supply chemistry to an area of the oral cavity, for example agents antimicrobials, unpleasant odor agents, flavor and aroma agents, antiplaque agents, antigengivitis agents, bleaching agents, or the like.
[00069] For example, in some embodiments, cleaning elements may comprise tufts. Tufts can comprise a plurality of individual filaments, which are firmly attached to the head. Such filaments can be polymeric and can include, for example, polyamide or polyester. The longitudinal and transverse dimensions of the filaments of the invention and the profile of the ends of the filaments can vary. In addition, the hardness, resilience and shape of the end of the filament may vary. Some examples of suitable dimensions include a length between about 3 mm to about 15 mm, or any individual number within that range. In addition, the filaments may include a substantially uniform cross-sectional dimension between about 100 and about 350 microns, or any individual number within that range. The ends of the filaments can be any suitable shape, examples of which include a soft tip, a rounded tip, a wedge-shaped tip, a pointed tip. In some embodiments, the filaments may include a dye that indicates wear on the filaments, as described in U.S. Patent No. 4,802,255. Some examples of filaments suitable for use with the brush are described in U.S. Patent No. 6,199,242. Other suitable examples of bristles include textured bristles, for example single and multiple component bristles (for example, bristles formed by the coextrusion of different polymers), ruffled bristles, gum massage bristles, bristles of varying configurations (for example, bristles that have multiple lumens), and / or combinations thereof.
[00070] Other suitable examples of cleaning elements include those described in U.S. Patent Application Publication Numbers 2002/0059685; 2005/0000043; 2004/0177462; 2005/0060822; 2004/0154112; U.S. Patent Nos. 6,151,745; 6,058,541; 6,041,467; 6,553,604; 6,564,416; 6,826,797; 6,993,804; 6,453,497; 6,993,804; 6,041,467; and U.S. Patent Applications No. serial 12 / 008.073, deposited on January 8, 2008, entitled, "TOOTHBRUSHES" (TOOTHBRUSHES) and 60 / 928.012, deposited on May 7, 2007, entitled "ORAL HYGIENE IMPLEMENTS" (IMPLEMENTOS DE HYGIENE BUCAL), all of which are incorporated herein by reference in their entirety. In addition, any suitable arrangement of cleaning elements can be used. Some suitable examples include those described in U.S. Patent Nos. 5,836,769; 6,564,416; 6,308,367; 6,108,851; 6,058,541; and 5,396,678.
[00071] In addition to bristles and / or tufts of bristles, cleaning elements may also include elastomeric structures, foams, combinations thereof, and the like. For example, cleaning elements may comprise elastomeric fins, as described in U.S. Patent No. 6,553,604 and in U.S. Patent Application Publication No. 2007 / 0251040A1. As yet another example, the cleaning elements may comprise cup-shaped elements, as described in U.S. Patent Publication No. 2004 / 0154112A1. In some embodiments, the cleaning elements may comprise a combination of elastomeric elements and bristles. As an example, a combination of fins and bristles can be used, a combination of elastomeric cup (s) and bristles can be used, and / or combinations of elastomeric elements either alone or in combination with bristles can be used. Combinations of elastomeric cleaning elements are described in U.S. Patent Publication No. 2009 / 0007357A1.
[00072] The cleaning elements and / or massage elements can be attached to the head in any suitable way. Conventional methods include stapling, tufting without anchors, and tufting with injection mold. For these cleaning elements which comprise an elastomer, these elements can be formed integrally with each other, for example having an integral base portion and extending outwardly or discreetly. The elastomer elements can be injection molded into the head.
[00073] In addition to the cleaning elements described above, the head may comprise a soft tissue cleaning product made of any suitable material. Some examples of suitable materials include elastomeric materials; polypropylene, polyethylene, etc .; similar, and / or combinations thereof. The soft tissue cleaner can comprise any suitable soft tissue cleaning elements. Some examples of such elements, as well as soft tissue cleaner configurations on a toothbrush are described in US patent applications No. 2006/0010628; 2005/0166344; 2005/0210612; 2006/0195995; 2008/0189888; 2006/0052806; 2004/0255416; 2005/0000049; 2005/0038461; 2004/0134007; 2006/0026784; 20070049956; 2008/0244849; 2005/0000043; 2007/140959; and in US Patent Nos. 5,980,542; 6,402,768; and 6,102,923.
[00074] In addition, for those modalities comprising elastomer elements on a first side of the head and a second side of the head, the second side being opposite the first side, the elastomer elements on both sides of the head can be unitarily formed. For example, the head sans of elastomeric elements may comprise openings therethrough, which may allow the elastomeric material to flow from the first side of the head to the second side of the head.
[00075] The materials for making at least a part, such as the cable section housing or the fastening section housing can be of any suitable plastic or non-plastic material, where typical plastic materials can comprise at least least one from the group consisting of polypropylene (PP), thermoplastic elastomer (TPE), polyoxymethylene (POM), a blend of polyester and polycarbonate such as Xylex available from SABIC, Saudi Arabia, styrene acrylate (ASA), polybutylene terephthalate ( PBT). Instead of plastic, metal, glass, or wood can also be chosen as the material to make at least part of the fastening section.
[00076] The dimensions and values presented in the present invention should not be understood as being strictly limited to the exact numerical values mentioned. Instead, unless otherwise specified, each of these dimensions is intended to mean both the mentioned value and a range of equivalent operating values around that value. For example, a dimension displayed as "40 mm" is intended to mean "about 40 mm".
