    Cross reference to related applications
    [0001] The present patent application refers generally to hearing protectors and is more particularly directed to pre-molded ear protectors of the snap type. Specifically, the present patent application refers to a new concept for an insertion stem for a snap-on ear protector that allows an easy and deep insertion of the ear protector with less pressure and less contact of the stem with the walls of the ear canal. This hearing protector will fit and provide comfortable sound attenuation for a greater number of individuals compared to prior art ear protectors.
    [0002] The pre-molded ear protectors are composed of different materials. One such material is a resilient polymeric foam, such as foam rubber, polyurethane or plasticized polyvinyl chloride. For example, U.S. Patent No. 5,188,123 discloses a snap-on ear protector comprising a soft, elastic foam body member having a rigid axially oriented stem by which insertion and removal of the member is facilitated. body into and from the ear canal. Another plug-in type hearing protector includes a central shaft and thence extends from a front end to at least one single flange member. These hearing protectors are usually composed of an injection molded resilient elastomer material, such as synthetic rubber or natural rubber materials. The flange element extends rearwardly from the front end of the shaft member and also extends rearwardly from the front end and is spaced apart so as to provide a clear annular space between the flange and the shaft. Such a hearing protector can be found in U.S. Patent No. 5,957,136.
    [0003] A more serious problem generally incurred with all these ear protectors precast with the prior art lies in the anatomical fact that the human ear canal varies greatly in size and geometry. Substantially the entire ear canal includes at least a curved portion so that there is no straight path between the outside of the ear and the inside of the ear. This is a human ear protection measure to avoid a direct path to the inner ear, which could be compromised by a finger, rod or any foreign object. As a result, a single-type precast prior art ear protector was not able to accommodate the wide range of human ear canals, both in size and geometry. Quite often, when inserting the pre-molded ear protectors from the prior art, the stem member could not be manipulated to insert the front end into the proper position to maximize attenuation without incurring discomfort when touching the side wall of the ear canal, irritating , thus, the ear canal while wearing the ear protector.
    [0004] The vast majority of existing snap-on hearing protectors have straight temples generally made of relatively rigid plastic materials (eg the ear protector described in U.S. Patent No. 5,188,123). However, to provide a proper insertion, the plastic shaft of this type of ear protector must be flexible/bendable as the human ear canal is not straight and varies in size and shape between individuals. However, to bend a plastic rod into the ear canal may not be ideal and may increase pressure and may not be comfortable for the user during insertion or during use.
    [0005] In U.S. Patent No. 3,811,437 and Re. 29,487, roll-type hearing protectors composed of viscoelastic polymeric foam are presented to be compressed, inserted into the ear canal and allowed to expand therein, to result in a complete and comfortable acoustic blockage of the ear canal. This type of ear protector fits the shape of the ear canal, but with current types of rod-mounted ear protectors, the rod portion does not fit. The roll-type foam ear protector has some deficiencies that prevent its use in certain hearing protection situations. This type of ear protector is designed for insertion by initially rolling it down between your thumb and fingers to compress the ear protector to a smaller size than the ear canal into which it will be inserted. For hygiene reasons, the user's hands must be clean at the time of use. In many noisy industrial environments, abrasive materials or aggressive chemicals are present and can be installed in the ear protector. Since these contaminants can be present on users' hands, the first step of hand cleaning can be cumbersome before using ear protectors. The present patent application is directed towards a project that will overcome the above deficiencies, as the ear protector is inserted using a stem member with a manipulable portion located on the external side of the ear canal. OVERVIEW
    [0006] With the present patent application, there is an attempt to provide a new and innovative hearing protection construction.
    [0007] With the present patent application, there is an attempt to provide a new and innovative hearing protection construction that can be used either with an injection molded resilient thermoplastic elastomer material, such as a synthetic rubber material or a material of the viscoelastic polymeric foam type.
    [0008] With the present patent application, there is an attempt to provide a hearing protector construction that can be produced in one size, but which provides easy insertion, user comfort and good sound attenuation for substantially the entire adult population.
    [0009] Other aspects of the present patent application will be obvious, in part, and will appear, in part, below. SUMMARY
    [00010] The hearing protector now shown includes a main body element with a front end. The main body element is circular or oval in cross-section, and can be formed either from an injection molded thermoplastic elastomer material, such as synthetic rubber material, or from a viscoelastic polymeric foam type material, or other types of plastic materials. acoustic foam that have quick recovery. An elongated rod member is attached to the main body member and can be located axially on the main body and the outwardly extending rod member and may terminate in an outer position with a manipulable portion.
    [00011] The stem member has a bent or wavy configuration as it extends outward from the main body of the ear canal so that while the main body of the ear protector is inserted into a wearer's ear canal, the stem member can be rotated during insertion with the manipulable portion to fit around the curved portion typical of the human ear canal, to house the main body so that it acoustically blocks the ear canal while at the same time making room in the stem member within the ear canal to minimize contact with the side walls of the ear canal. The bent stem member can either be axially aligned with the main body or can be eccentric or axially displaced by its extension to increase the spacing effect when turning the ear protector into the ear canal. The bent rod member may include one or more portions which are angularly displaced from adjacent portions 7/32 by the extension of the rod member and with such adjacent angularly displaced rod portions being curved or straight within certain dimensional ranges to be substantially suitable for the entire adult population.
    [00012] In the present patent application, there is no need to bend the stem to insert the ear protector. Just by twisting and/or pushing the manipulable portion of the stem member during insertion, the user will be able to find the best position for the stem to be away from the side walls in the curved portion typical of the human ear canal. The stem member inside the ear canal has less contact with the walls of the ear canal (less pressure) because the angularly displaced portions of the adjacent stem are curved or straight within certain dimensional ranges, forming the warped configuration. The curved or straight angularly displaced portions of the adjacent rod can be two or three dimensional in nature and are designed to provide a comfortable fit to a large number of the population. In addition, as indicated above, for added versatility, the rear end of the stem member carrying the hearing protector body can be eccentric against the centerline of the main body of the hearing protector in order to increase the rotational effect.

DESCRIPTION OF THE PREFERRED APPLICATIONS
    [00027] Referring now to Figures 1 to 7, applications of the present patent application are shown and the same reference numerals refer to structures with a similar function, including a main body element 10 and a rod member elongate 12 extending outwardly and axially from and at least partially within the main body element or attached to the main body element 10.
    [00028] In Figures 1, 2 and 7, the construction of the ear protector of the present patent application uses a soft and resilient polymeric foam body comprising a homogeneous and smoothly contoured viscoelastic main body member adapted in size and shape to be inserted into the human ear canal. In Figure 1, the main body element has a projectile shape 14 and in Figure 2 the main body element has a hemispherical cocoon shape 16. In Figure 7, the main body element has an elongated bulbous curved shape 18 including a flange portion 20. In Figures 3 to 6, the main body element 10 is an injection molded resilient elastomer material, such as natural or synthetic rubber material in Figures 3 to 5 has lateral projections in the nature of one or more of the flange 22. In Figure 6, main body element 10 has an elongated bulbous curved shape 24 including a flange portion 26. Each main body element 10 has a front end 28 and a base end 30. While the preferred transverse shape if the main body element 10 is circular, it will be appreciated that the transverse shape is also oval or elliptical.
    [00029] Stem member 12 is an elongated member that may be tubular or solid across its cross section and may be uniform or non-uniform along its length. In a preferred structure, the elongated rod has two ends, one end 32 is located at and, in some applications, secured to the interior of the front end portion 28 of the main body member 10. The rod 12 then extends axially and outward. from the front end portion 28 and through the base end 30. The other end 34 of the rod may terminate at a point outside to or adjacent to the base end 30 and forms a manipulable portion 36 of the rod 12. The rod is sufficiently rigid to which can allow manipulation of the main body element 10 so that the ear protector can be housed in the ear canal for maximum attenuation while at the same time being rotated to ensure spacing between the stem member and the side walls of the canal auditory.
    [00030] As can be seen in Figures 1 to 7, the shank 12 and, in particular, the portion of the shank between the end 32 and the manipulable portion 36 has a bent or wavy configuration and specifically has adjacent shank portions displaced in a manner straight or curved angles that can adapt to the shape of a typical ear canal, while extending from the inside to the outside of the inner ear. Since there may be variations in the shape of the ear canal between different users of hearing protectors, turning the ear protector while being inserted into the ear canal creates the ability to accommodate these variations in the shape of the ear canal by changing the position of the adjacent stem portions angularly displaced straight or curved stem 12 in the ear canal.
    [00031] The transverse dimension of stem 12 should not be so large as to prevent easy insertion of the ear protector into the small sized ear canals. Stem 12 may be of any convenient length so that, for the applications of Figures 1 to 5, the manipulable portion 36 extends beyond the main body member 10. The manipulable portion may be formed as a flared end to provide a member. of insertion and removal for the main body element 10. The exact length selected for the rod 12 including the manipulable portion 36 will largely be a matter of choice, but the dimensions of the portion of the rod between the end 32 and the manipulable portion 36 will have a reach in length and deviation from a central axis that will accommodate the greatest number of variations in size and shape of the ear canals. For the applications of Figures 6 and 7, the manipulable portion 36 is located adjacent the base end 30 of the main body member 10, but with the same dimensional considerations for the rod 12 so that the length and offset from the central axis that will accommodate the greatest number of variations in the size and shape of ear canals are applied.
    [00032] The bent stem member can be axially aligned with the main body or can be eccentric or axially displaced along its length to increase the spacing effect when turning the ear protector into the ear canal. The dimensions, geometry and materials of construction applied for the stem 12 are selected so that the stem 12 is rigid enough to allow manipulation of the main body element 10 so that the ear protector is housed in the ear canal for an attenuation maximum, while at the same time being rotated to ensure a spacing between the stem member and the side walls of the ear canal.
    [00033] The rod 12 can be constructed of any suitable material, paper, rubber, cardboard and plastic tube or bar can be used as long as the material is suitably rigid in nature and can be formed into the appropriately bent or corrugated configuration. It is important, for the applications of Figures 1 to 5, that the end 32 of the rod 12 is securely attached to the main body element 10 so as to prevent separation of the rod 12 from the main body element 10 during use. If separation occurs, it may be difficult to remove the ear protector if it is deeply inserted into the ear canal and the stem is no longer available to aid removal. This can be achieved in any known way, such as the use of adhesives or by solvent or thermal soldering or through the use of a bond obtained by a mechanical lock. Such a connection can occur with the rod member 12 partially inserted into the main body element 10 or the attachment can be provided exactly in the rear frame 30 of the main body element 10 in any of the ways described above. Furthermore, the main body element 10 can be attached to the respective rod 12 during the molding operation. Stem 12 can be used as an insert in the mold for main body 10, end 32 acting as a male mold member for main body element 10. While the molding formulation fits in the mold to form the body element main body 10, the main body element 10 can be firmly joined to the end 32 of the rod 12.
    [00034] Both applications of Figures 6 and 7 include enlarged portions 26 and 20 for applications of Figures 6 and 7, respectively. These widened portions 26 and 20 can normally prevent the ear protector of this application from entering too deeply into the ear canal, as the widened portions 26 and 20 restrict insertion as these widened portions approach the outer opening of the ear canal. However, even if the ear protector is inserted deeply, the flared portions 26 and 20 can still be used to remove the ear protector from the ear canal. Even if the stem member 12, initially attached to the main body 10 by being located within the main body 10, separates from the main body element 10, the flared portions 26 and 20 can be used to remove the ear protector. In the application of Figure 7, the flared end 20 can completely coat the manipulable portion of the stem member so that the stem member is not visible, but the stem and main body element can still rotate to properly accommodate the ear protector. in the ear canal with spacing of the stem member from the walls of the ear canal.
    [00035] The contoured main body element 10 extending from the front end 28 can be formed with a rounded configuration to aid insertion of the ear protector. The length of the main body element 10 relative to its maximum transverse dimension is subject to considerable variations, as can be seen in several applications of the present patent application, and is not normally critical. For example, the shape of the main body element 10 of each hearing protector shown in Figures 2 and 5 includes a hemispherical cocoon portion and its length to diameter ratio contrasts with the applications of Figures 1, 6 and 7, where the elements of frame 10 are elongated and have a greater proportion of length to diameter. Similarly, the applications of Figures 3 and 4 are also elongated and have a greater proportion of length to diameter.
    [00036] Figures 8, 8A, 9 and 9A schematically illustrate generalized versions of the hearing protector of the present patent application and show in Figure 8 and 8A the stem member axially aligned with the main body of the hearing protector and in Figures 9 and 9A the stem member is eccentric or axially displaced along its extension with the main structure of the hearing protector. In addition, the range of dimensions for the bent or curled portion of stem 12 are shown with preferred dimensions to provide easy insertion, user comfort and good sound attenuation for substantially the entire adult population. The main body element 10 shown in Figures 8, 8A, 9 and 9A represents any of the applications of Figures 1 to 7. Similarly, manipulable portion 36 of rod 12 may have the flat configuration shown in Figures 1 to 5 or have the design shown in Figures 6 and 7 or further may be nothing more than an extension 40 of the rod 12, as shown by the dotted lines in Figures 8, 8A, 9 and 9A.
    [00037] In Figures 8 and 9, the rod member is shown having a curved shape and with the rod member of Figure 8 having a simpler curved shape composed of curved rod portions compared to the curved shape of the rod member. Figure 9. Similarly, in Figures 8A and 9A, the rod member has portions of the adjacent rod angularly displaced straight and with the rod member of Figure 8A having two portions of the adjacent rod angularly displaced straight and the member of the shank of Figure 9A with three portions of the adjacent shank angularly displaced straight. It will be appreciated that the simpler shape of the rod member of Figures 8 and 8A can be used either with the axis aligned, as shown in Figures 8 and 8A, or offset, as shown in Figures 9 and 9A, and the same for the more complex shape of the stem member of Figures 9 and 9A. In addition, the rod member may also be formed from a combination of angularly displaced straight and curved portions of the adjacent rod. With both the curved shaped shank member and the straight portions of the adjacent shank angularly offset or a combination thereof, the number of shank portions can be varied since the shank member can accommodate a wide variety of channel shapes. ear of the human population.
    [00038] As shown in Figures 8, 8A, 9 and 9A, the distance between the end 32 of the rod member 12 and any shape of the manipulable portion 36 of the rod member 12 must be between 6 mm to 25 mm with a distance 14 mm is preferred. In Figures 8 and 8A, the manipulable portion 36 and the main body element 10 are located by the same axis 50 and the maximum deviation range of the axis 50 by the bent or waved portion of the rod member 12 being 0.8 mm to 6 mm and with a maximum preferred deviation being 1.3 mm. In Figures 9 and 9A the manipulable portion 36 is displaced from the main body element 10 and the manipulable portion 36 and the main body element 10 are located along the two parallel axes 52 and 54. The range of maximum deviation between the axes 52 and 54 by the bent or curled portion of the stem member 12 being 0.8 mm and 6 mm and with a preferred maximum deviation being 1.3 mm. The bent stem member can either be axially aligned with the main body as in Figures 8 and 8A or can be eccentric or axially displaced along its extension as in Figures 9 and 9A to increase the spacing effect during the turning of the hearing protector inside the ear canal.
    [00039] Figures 10A to 10E illustrate a common ear structure and the positioning of a prior art hearing protector in Figures 10B and 10C and the positioning of the ear protectors of the present patent application in the ear canal in Figures 10D and 10E . In Figure 10A it can be seen that the typical ear structure includes the curved structure of the external auditory meatus or ear canal with the lateral walls leading to the eardrum. In appearance, it is a slightly curved tube that extends into the floor of the auricle, or the protruding portion of the outer ear, and ends at the tympanic membrane out of sight, which separates it from the middle ear. Figures 10B and 10C illustrate a prior art hearing protector with a main body element 100 and a straight stem 102. Figure 10B shows the ear protector initially inserted to block the ear canal and how the ear protector is inserted deeper to enlarge attenuating external noise, as shown in Figure 10C, the stem 102 will bend as it touches the side walls and will be uncomfortable for the user due to the stem's contact with the side walls of the ear canal. Figures 10D and 10E show any of the applications of Figures 1 to 7 with the main body element 10 and the stem member 12 fully inserted into the ear canal and with the stem member 12 positioned to be out of contact with the side walls of the ear canal to minimize contact with the side walls. Figure 10D illustrates rod member 12 with a curved shape as shown in Figures 8 and 9 and Figure 10E illustrates rod member 12 with portions of adjacent rod angularly offset straight, as shown in Figures 8A and 9A.
    [00040] Figure 11 illustrates the main body element 10 of the hearing protector and in particular represents the applications of Figures 1 to 5 being inserted into an ear canal 56 of a human subject 58 and with the stem member 12 being manipulated by the fingers 60 of the human subject 58 so that the ear protector can be housed in the ear canal 56 for maximum attenuation, while at the same time being rotated as shown by the arrow 62 to ensure a spacing to minimize contact between the stem member 12 and the side walls 64 of the typical curved portion 66 in the human ear canal 56. If the bent stem member 12 is eccentric or axially displaced along its length as in Figure 5, this increases the spacing effect during rotation of the stem member within the channel. auditory.
    [00041] Figure 12 illustrates the main body element 10 of the hearing protector and in particular represents the applications of Figures 6 and 7 being inserted into an ear canal 56 of a human subject 58 and with the manipulable portion 36 and thus the limb of stem 12 being pushed as shown by arrow 68 by fingers 60 of human subject 58 so that the ear protector can be accommodated to fit around the typical curved portion in human ear canal 56 for maximum attenuation, while at the same time the limb of stem 12 rotates as shown by arrow 70 to ensure spacing between stem member 12 and side walls 64 of ear canal 56. Rotation of stem member 12 occurs during insertion as stem member conforms to shape ear canal to find the path of least resistance. If the bent stem member is eccentric or displaced axially along its length, as in Figures 9 and 9A, this increases the spacing effect during rotation of the stem member within the ear canal.
    [00042] The present patent application is not limited to any specific design for the main body element or stem member including the manipulable portion of the stem member. There are a large number of designs currently used for a main body element of a hearing protector and the only limiting requirement for the present patent application is that the main body element be capable of being inserted a significant distance into the ear canal to provide high attenuation levels. Similarly, the manipulable portion of the stem member can take any shape as it can be manipulated by a user of the hearing protector. Therefore, the manipulable portion may be flattened, rounded, oval, straight or bent or any other shape and may merely be an extension of the stem itself.
    [00043] Human subjects, with different sizes and geometries of ear canals, have used the ear protectors of the present patent application in noisy environments. These subjects reported that the hearing protectors are easy to use, comfortable during insertion, use and removal, and provided adequate attenuation for their needs.
    [00044] Although the present patent application has been described and displayed using specific preferred applications, it should be appreciated that various adaptations and modifications can be made and the present patent application should be limited only by the claims attached.
    [00045] All elements, parts and steps described herein are preferably included. It should be understood that any of these elements, parts and steps can be replaced by other elements, parts and steps or deleted all together as will be obvious to those skilled in the art.
    [00046] In general, this document discloses a hearing protector for insertion into the human ear canal of a user, where the human ear canal has side walls and a typical curved portion. A soft resilient body has a main body element with a front end for insertion into the human ear canal. An elongated rod has two ends with one end attached to the main body element. The rod extends away from the main body element and away from the front end. The other end of the rod forms a manipulable portion of the rod. The stem is rigid enough to allow manipulation of the main body element within the user's ear canal. The stem member has a bent or curved configuration within the ear canal as it extends outward from the main body to the manipulable portion of the stem. While the front end of the main body element is inserted into the ear canal, the stem member is rotated during insertion with the manipulable portion to fit around the curved portion typical in the human ear canal. This accommodates the main body to acoustically block the ear canal, while at the same time pulling the stem member within the typical curved portion of the ear canal to minimize contact with the side walls of the ear canal.
