FIELD OF THE INVENTION
[001] The present application concerns a device for trimming hair. HISTORY OF THE INVENTION
[002] Trimming devices exist to cut body and facial hair. Such devices are known as 'hair trimmers' or hair trimmers and typically comprise a set of fixed blades and an adjacent set of movable blades that swing from side to side in relation to the fixed blades to cut excess hair between the two sets of blades. During the use of such devices, a user may have difficulty trimming hair, especially facial hair, with precision in order to achieve a desired hair length.
[003] One way to achieve a desired hair length is to use interchangeable combs. Such combs, also known as cutting guides, act as a spacer to space the blades of a user's skin. Such a comb has a guide surface, which is arranged against a user's skin to determine the length of the nib. Therefore, when the comb is moved along a user's skin, then the hair can be cut to an established length.
[004] A problem when using interchangeable combs is the need for different combs to provide different hair lengths. Therefore, it is known that it is variable to provide a comb which is mountable to the body of a device for trimming hair and is movable in relation to the body, so that the distance between the blades and the guide surface is variable.
[005] However, it is difficult to accurately determine the length of the nib with an adjustable comb. SUMMARY OF THE INVENTION
[006] It is the aim of the invention to provide a device for trimming hair, which substantially relieves or solves the problems mentioned above, among others.
[007] According to the present invention, a device for trimming hair is provided comprising a body with a set of cutting blades, a cutting guide on the body, the position of the cutting guide being adjustable in relation to the set of cutting blades cutting to provide a cutting distance from a user's skin, allowing the hair to be cut to a desired length, and a locking unit to lock the cutting guide in a desired position in relation to the set of cutting blades, where the locking unit comprises a first locking element, a second locking element and a plurality of receiving compartments, the first and second locking elements being movable with each other to alternatively settle in or in one of the receiving compartments when the position of the cutting guide is adjusted in relation to the set of cutting blades to lock the cutting guide in different positions.
[008] The locking comprises a plurality of receiving compartments. The first and second locking elements can alternatively be established in the receiving compartments, once the position of the cutting guide is adjusted in relation to the set of cutting blades.
[009] An edge is formed between adjacent receiving compartments; the first and second locking elements can alternatively be established on one of the edges when the other of the first and second locking elements is received in one of the receiving compartments.
[010] With the above arrangement, it is possible to double the number of discrete locking positions of the cutting guide in relation to the set of cutting blades. In particular, it is possible to provide twice the number of locking positions for each receiving compartment. This makes it possible for the locking unit to have receiving compartments and locking elements of a suitable size to provide rigidity of the locking unit. Also, it is possible to maintain a spacing between the receiving compartments despite the reduction in the distance between the discrete locking positions.
[011] With this arrangement, it is possible to provide a large number of discrete locking positions.
[012] With the above provision, it is possible to maintain a strict division between the receiving compartments, despite reducing the distance between discrete locking positions.
[013] The plurality of receiving compartments may be arranged in an arrangement along the path of the cutting guide in relation to the set of cutting blades.
[014] The first and second locking elements can be adjacent to each other and can alternatively be received in the receiving compartments, since the position of the cutting guide is adjusted in relation to the set of cutting blades to lock the cutting guide in different positions. An advantage of this arrangement is that the size of the locking unit is minimized.
[015] The first and second locking elements can be spaced apart and can alternatively be received in different receiving compartments, since the position of the cutting guide is adjusted in relation to the set of cutting blades to lock the cutting guide cut in different positions. An advantage of this arrangement is that the locking elements cannot touch. In addition, the failure of one locking element must not result in the failure of the other locking element, due to the locking elements being spaced apart.
[016] The first and second locking elements can be received in an opening. A booster unit can act on the first and second locking elements to propel them to protrude from the opening. Receiving compartments can oppose the mounting surface.
[017] With the above provisions, the locking elements are driven to keep the locking unit in a locked condition. Therefore, the movement of the cutting guide is restricted when the hair trimmer is in use.
[018] The device for trimming hair may further comprise an opening unit configured to selectively propel the first and second locking element out of or from each receiving compartment.
[019] With this arrangement, it is possible to detach the locking unit. Therefore, it is simple to adjust the position of the cutting guide in relation to the set of cutting blades to lock the cutting guide in different positions.
[020] The opening unit can comprise an opening face configured to act on the first and the second locking element. The opening unit can be movable between an operational position in which the opening face acts on the first and the second locking element to propel them out of the receiving compartments and a retracted position.
[021] The opening face of the opening unit can extend the level or be recessed from a base of the receiving compartments when the opening unit is in the stowed position. This provides a meaning for the locking elements to be safely received in or in each receiving compartment.
[022] The opening face can have one or more alignment elements formed on it. The aligning elements can be protrusions or indentations formed on the opening face. The above provisions provide tactile feedback to a user. This provides a meaning for a user to accurately determine the position of the cutting guide. In addition, the locking elements can be easily aligned with or in each receiving compartment.
[023] The aligning elements can be configured to align one of the locking elements with at least one receiving compartment. Therefore, it is possible to precisely align the locking elements with the or each of the receiving compartments.
[024] The aligning elements can be configured to allow the locking elements to slide along the opening face when the opening unit is in its operational position. This means that it is possible to provide feedback to a user without exerting excessive force to move the cutting guide.
[025] The first and second locking elements can each have a locking section configured to be received in or in each of the receiving compartments, and a release section against which the opening unit is configured to act. The release section can project from the locking section.
[026] With the above provisions, it is possible to easily detach the locking elements from the receiving compartments.
[027] A part of the locking section can extend on each side of the release section. Therefore, the opening unit can exert a balanced force on each of the locking elements. In addition, the locking elements are propelled in the direction of movement.
[028] The first and second locking elements can be on the body and at least one receiving compartment can be on the cutting guide. This means that the ease of manufacture is maximized.
[029] The locking unit can be configured to lock the cutting guide in two or more discrete positions. With the above arrangement, it is possible to precisely determine the cut length.
[030] The two or more discrete positions are spaced by 2 mm or less, preferably about 1 mm. Therefore, it is possible to control the cutting length precisely.
[031] These and other aspects of the present invention will be apparent and elucidated with reference to the achievements described below. BRIEF DESCRIPTION OF THE DRAWINGS

[050] Referring to Figures 1 to 5, a device 10 is presented for cutting and trimming hair, such as, among others, facial or body hair. The trimming device 10 comprises a body 11 with a blade part 20 and a handle part 30. The blade part 20 is fixedly mounted on one end of the handle part 30. The blade part 20, acting as a set of blades from cut, extends from one end of the handle part 30. The handle part 30 is elongated and held by a user during use to orient and position the device to trim by 10 against a user's skin. The blade part 20 is configured to cut hair when the device 10 is operated. The device for trimming by 10 further comprises the cutting guide 40, which is provided in the body 11 and has an assembly part 41 and a head part 42. The cutting guide 40, also known as comb, extends over the part blade 20. That is, the head part 42 extends over the set of cutting blades 20.
[051] The assembly part 41 of the cutting guide 40 is attached to the handle part 30. The head part 42 extends from the assembly part 41 as well as over the set of cutting blades 20 and has a plurality of comb elements 43. The comb elements 43 are spaced apart so that the hairs can pass between the comb elements 43. Therefore, the hairs are able to be received by the head part 42 of the cutting guide 40 and to be provided in the blade part 20 to be trimmed by it. The head part 42 of the cutting guide 40 has a guide surface 44, which is arranged to be positioned against the face or hair of a user to orient and position the device for trimming by the 10 and therefore the set of cutting blades in relation to the skin. The guide surface 44 of the cutting guide 40 is defined by end surfaces of the combs 43. That is, the end surfaces of the comb elements 43 are aligned with each other to form the guide surface 44. The guide surface 44 of each comb element 43 is spaced from the set of cutting blades 20 when the cutting guide 40 is detachable to 11.
[052] In the present embodiment, the cutting guide 40 is detachably fixed to the handle part 30 and configured to slide in relation to the handle 30 to adjust the desired cutting length. The cutting guide 40 allows a user to precisely trim the hair to a predetermined length in relation to the skin / body.
[053] The cutting guide 40 is mounted on the handle part 30 of the body 11 by means of a mounting unit 50. The mounting unit 50, or guide mechanism, provides a means for slidingly attaching the cutting guide 40 to the handle part 30. However, it will be understood that in an alternative embodiment, the cutting guide 40 can be detachably fixed to the blade part 20. The assembly unit 50 comprises a first assembly part 51 on the body 11 and a second mounting part 52 on the cutting guide 40. The first and second mounting parts 51, 52 slide together.
[054] A locking unit 60 is provided to lock the cutting guide 40 in position on the handle part 30. That is, the locking unit 60 is provided to fix the cutting guide 40 in a desired position on the handle part 30 so that the guide surface 44 is arranged at a desired distance from the blade part 20. The locking unit 60 comprises a first locking part 61 on the body 11 and a second locking part 62 on the cutting guide 40. The first and second locking parts 61, 62 are configured to be removably attached to each other.
[055] When the cutting guide 40 is moved along the body 11 of the device to trim by 10 and is fixed in a desired position, it is possible to establish the distance between the set of cutting blades 20 and a guide guide surface cutter 40 to determine the length to which the hairs will be trimmed. That is, the cutting guide 40 is slidable along the handle part 30 to adjust the position of the head part 42 in relation to the blade part 20 and is fixable to the handle part 30 to fix the adjustment guide in a desired position. The mounting unit 50 and the locking unit 60 together form an attachment means or mechanism.
[056] The blade part 20, acting as a set of cutting blades, comprises a fixed blade plate 21 and a movable blade plate 22. The movable blade plate 22 is adjacent to the fixed blade plate 21 and, during use, it is driven by a motor (not shown) to oscillate from side to side of the fixed blade plate 21. Each blade plate 21, 22 comprises a plurality of cutting teeth 23. The hairs are cut by means of a cutting action, since they protrude between teeth 23 of the two blade plates 21, 22 and the movable blade plate 22 oscillates from side to side of the fixed blade plate 21.
[057] The handle part 30 forms a housing and includes a controller for operating the device to trim at 10, a user input such as one or more buttons (not shown) and a power supply unit. The power supply unit (not shown) is a rechargeable battery, although it will be appreciated that a mains operated power supply can be used. The components are received in the housing of the handle part 30.
[058] The handle part 30 has an outer surface 32, where the first part of the assembly 51 of the assembly unit 50 is located. The first part of the assembly 51 comprises a mounting rail 53, which protrudes from the surface outer part 32 of the handle part 30. The mounting rail 53 is integrally formed with the handle part 30 and is elongated and extends parallel to the longitudinal axis of the handle part 30. The mounting rail 53 has a mounting surface 54 and parallel side walls 55. The mounting surface 54 is flat and extends between the parallel side walls 55. The mounting rail 53 determines the path of the cutting guide 40 along the body 11.
[059] A mounting edge 56 extends along the length of each side wall 55. The mounting edges 56 define the mounting grooves 57. Each mounting groove 57 is formed between the corresponding mounting edge 56 and the surface outer part 32 of the handle part 30. The mounting inserts 57 extend parallel to each other, but spaced apart.
[060] The first part of the lock 61 of the locking unit 60 extends from the handle part 30. In the present embodiment, the first part of the lock 61 is in the first part of the assembly 51 of the assembly unit 50. An opening 63 is formed on the mounting surface 54. The opening 63 extends through the mounting rail 53. That is, the opening 63 extends from the mounting surface 54, in the housing of the handle part 30. A rear view of opening 63 is shown in Figure 2 with part of the housing cut out ...
[061] A first locking element 64 and a second locking element 65 are received at opening 63. The first and second locking element 64, 65 form part of the first locking part 61. The first and second locking elements 64 .65 extends from opening 63.
[062] The first and second locking elements 64, 65 are arranged adjacent to each other in opening 63. Each locking element 64, 65 is slidable along opening 63. That is, opening 63 defines a passage along the which each of the first and second locking elements 64, 65 are slidable. The first and second locking elements 61, 62 are slidable independently from each other along the opening 56.
[063] Now, referring in particular to Figures 6 to 9, the first and second locking elements 64, 65 will be described in detail.
[064] The first locking element 64 has a hitch or front end 66 and a support or rear end 67. The hitch end 66 of the first locking element 64 extends from opening 63. That is, during In use, the engagement end 66 is arranged to normally protrude from the mounting surface 54 of the mounting unit 50. The support end 67 of the first locking element 64 is arranged in opening 63. The support end 67 of the the first locking element 64 is received between a side surface section of the opening 63 and the second locking element 65. Therefore, the first locking element 64 is supported and driven in the opening 63. A reference face of the first locking element 64 is configured to be opposed to a corresponding reference face of the second locking element 65.
[065] A limiter 68 is provided at the support end 67 of the first locking element 64 to limit the movement of the first locking element 64. That is, the limiter 68 is configured to limit the extent so that the engaging end 66 can achieve protrudes from the mounting surface 54. The stop 68 is opposite an inner end 69 of the opening 63 to determine the maximum extent of the first locking element 64 of the mounting surface 54. It will be understood that the stop 68 moves away from the inner end 69 of the opening 63 when the engaging end 66 of the first locking element 64 is retracted towards the opening 63. The inner end 69 of the opening 63 acts as an end stop.
[066] The engagement end 66 of the first locking element 64 has a locking section 70 and a release section 71. The locking section 70 comprises two parts - first and second part of the locking section 70a, 70b. The first and second part of the locking section 70a, 70b are arranged on each side of the release section 71. Although, the locking section 70 comprises the first and second part of the locking section 70a, 70b in the present arrangement, it is meant - in an alternative arrangement a single part of the locking section or another number of parts of the locking section can be used.
[067] Each part of the locking section 70a, 70b is a spare tongue that is arranged to protrude from the mounting surface 54. Each part of the locking section 70a, 70b has a free end. A locking surface 72 expands in the opposite direction to the free end. The locking surface 72 extends at an angle oblique to the direction of movement of the first locking element 64.
[068] The release section 71 of the first locking element 64 is provided between the parts of the locking section 70a, 70b. The release section 71 extends beyond the locking section 70. That is, the release section 71 extends from the free end of the locking section 70. The release section 71 forms a release tab. Therefore, when a force acts on the release section, the locking section 70 is propelled to retract in one direction within the opening 63.
[069] The second locking element 65 has a latch or front end 73 and a supporting or rear end 74. The latching end 73 of the second locking element 65 extends from opening 63. That is, during In use, the engaging end 73 of the second locking element 65 is arranged to normally protrude from the mounting surface 54 of the mounting unit 50. The supporting end 74 of the second locking element 65 is arranged in the opening 63. The support end 74 of the second locking element 65 is received between a section of the lateral surface of the opening 63 and the first locking element 64. Therefore, the second locking element 65 is supported and guided in the opening 63.
[070] A limiter (not shown) is provided at the support end 74 of the second locking element 65. The limiter (not shown) is provided to limit the movement of the second locking element 65. That is, the limiter limits the extent so that the engaging end 73 of the second locking element 65 is able to project from the mounting surface 54. The stop is opposite the inner end 69 of the opening 63 to determine the maximum extension of the second locking element 65 to from the mounting surface 54. It will be understood that the stop moves in the opposite direction to the inner end 69 of the opening 63 when the engaging end 73 of the second locking element 65 is retracted towards the opening 63. At present the limiters are protrusions extending from the respective first and second locking element 64, 65.
[071] The engagement end 73 of the second locking element 65 has a locking section 75 and a release section 76. Locking section 75 comprises two parts - first and second part of locking section 75a, 75b, which are arranged on each side of the release section 76. Although the locking section 75 of the second locking element 65 comprises the first and second part of the locking section 75a, 75b in the present arrangement, it will be understood that in a disposition Alternatively, a single part of the locking section or another number of the parts of the locking section can be used.
[072] Each part of the locking section 75a, 75b of the second locking element 65 is a spare tongue that is arranged to protrude from the mounting surface 54. Each part of the locking section 75a, 75b of the second locking element lock 65 has a free end. The locking surface 77 of the second locking element 65 expands in the opposite direction to the free end. The locking surface 77 extends at an oblique angle to the direction of movement of the second locking element 65.
[073] The release section 76 of the second locking element 65 is provided between the parts of the locking section 75a, 75b. The release section 76 extends beyond the locking section 75. That is, the release section 76 extends from the free end of the locking section 75 of the second locking element 65. The release section 76 forms a release latch. Therefore, when a force acts on the release section 76, the locking section 75 of the second locking element 65 is propelled to retract in one direction within the opening 63.
[074] The first and second locking elements 64, 65 are elongated. That is, the engagement end 66, 73 of each of the first and second locking element 64, 65 is elongated. The engagement ends of the first and second locking elements 64, 65 extend parallel to each other and extend perpendicular to the longitudinal axis of the handle part. The coupling end 66, 73 extends through the movement path of the cutting guide 40 along the handle part 30. The coupling ends 66, 73 of the first and second locking element 64, 65 extend perpendicularly to the mounting grooves 57 formed by the mounting rail 51.
[075] The release section 71 of the first locking element 64 is adjacent to the release section 76 of the second locking element 65. Similarly, the locking section 70 of the first locking element 64 is adjacent to the locking 75 of the second locking element 65. Therefore, the release sections and the locking sections are aligned with each other, and edges of the locking section and the release section are aligned.
[076] The first and second locking elements 64, 65 and opening 63 are configured so that the first and second locking elements 64, 65 are able to slide relative to the handle part 30 only along a plane. The first and second locking elements 64, 65 are configured to slide in a radial direction to the longitudinal axis of the handle part 30.
[077] The first and second locking elements 64, 65 are driven in a direction outside of the opening 63 through a drive or drive mechanism 80 (see Figure 2). Booster unit 80 comprises a first booster member 81 arranged to act on the first locking element 64 and a second booster member 82 arranged to act on the second locking element 65. The first and second booster member 81, 82 are resilient.
[078] The first booster member 81 is a pair of resilient arms. One end of each arm is opposed and acts on a support end 67 of the first locking element 64. The first pusher member 81 is configured to push the first locking element 64 to slide from opening 63. That is , the first pusher member 81 pushes an engaging end 73 of the first locking element 64 to protrude from the opening 63. As described below, the range of motion of the first locking member 64 is restricted by the limiter 68. However, it will be understood that the driving member 81 can act according to limiting means.
[079] Similarly, the second booster member 82 is a pair of resilient arms. One end of each arm is opposed and acts on the support end 74 of the second locking element 65. The second pusher member 82 is configured to drive the second locking element 65 to slide from opening 63. That is , the second pusher member 82 pushes the engaging end 73 of the second locking element 65 to project from the opening 63. As described above, the range of motion of the second locking member 65 is restricted by the limiter. However, it will be understood that the driving member 82 can act as a means of limiting.
[080] In the present embodiment, the first and second driving member 81, 82 are fully formed, however, it will be understood that they can be separated. The first and second pusher members act on the first and second locking elements 64, 65 with each other independently.
[081] The cutting guide 40 is mounted to the handle part 30 of the body 11 by the mounting unit 50. The second mounting part 52 of the mounting unit 50 is on the cutting guide 40, and slidably mounts the first part of the mounting 51 on the handle part 30. The second part of the mounting section 52 comprises a channel 45 formed on the mounting part 41. The channel 45 is formed on a rear side of the mounting 41 and has a base 46 and in opposition to the walls side 47. The side walls 47 extend parallel to each other, but are spacious. The base of the channel 46 extends between the side walls 47. The channel 45 is elongated.
[082] The mounting rail 53 of the first part of mounting 51 is received in channel 45 of the second part of mounting 52. The width of channel 45 corresponds to the width of mounting rail 53 between the ends of mounting flanges 48 on rail 53 The depth of the channel 45 corresponds to the height of the mounting rail 53.
[083] Channel 45 is open at one end and has an end wall (not shown) at the other end. Therefore, it is possible to slide the mounting rail 53 along the channel 45 from the open end of the channel 45. The end wall acts as an end stop to limit the movement of the mounting rail 53 along the channel 45 and, therefore, the movement of the cutting guide 40 along the handle part 30.
[084] Mounting flanges 48 extend from each of the side walls 47. Mounting flanges 48 are spaced from the base of the channel 46. The distance between each mounting flange 48 and the base 46 of the channel 45 corresponds to the thickness of the mounting edges 56 formed on the mounting rail 53. Therefore, the mounting flanges 48 of the second mounting part 52 are slidably received in the mounting slots 57 of the first mounting part 52. The mounting edges 56 they are slidably received between the mounting flanges 48 of the second part of the assembly 52 and the base 46 of the channel 45 when the mounting rail 53 slides along the channel 45. Therefore, the cutting guide 40 is prevented from sliding along of a trajectory in a plane of movement when the first and second parts of the assemblies 51, 52 are slidably attached to each other.
[085] The cutting guide 40 is fixed in position on the handle part 30 by the locking unit 60. The second locking part 62 of the locking unit is on the cutting guide 40, and fits releasably to the first part of the locking 61 in the handle part 30. The second locking part 62 comprises a plurality of receiving fittings 83. The receiving fittings 83 are formed at the base 46 of the channel 45. The receiving fittings 83 are arranged parallel to each other. Receiver housings 83 are arranged in a linear arrangement.
[086] Adjacent receiver grooves 83 are separated by a receiver edge 84. In addition, each receiver groove 83 is connected by two receiver edges 84. An upper end of each edge 84 is flat with the base plane 46 of channel 45 .
[087] In the present arrangement, the centers of the adjacent receiver fittings are spaced about 2 mm apart. Similarly, the centers of adjacent edges 84 are spaced about 2 mm apart. Therefore, the distance between the center of a receiver socket 83 and one of the adjacent receiver edges 84 is about 1 mm.
[088] Each receiver socket 83 has two side walls 85 and a base 86. The side walls of socket 85 diverge from the socket base 86 until the opening of the receiver socket 83 (not shown in figures 10 below). Therefore, the side walls extend at an oblique angle to the base of the channel 46. The divergent shape acts to facilitate the location of the locating elements 64, 65 in the corresponding receiver socket 83. Each receiver socket 83 is configured to receive one of the locking elements 64, 65. That is, each receiver socket 83 is arranged to receive a single locking element 64, 65 at a time. However, each receiver socket 83 is able to alternatively receive the first and second locking elements 64, 65.
[089] The locking unit 60 also has an opening unit 90 which comprises an exhaust member 91, which is elongated and is on the cutting guide 40. The exhaust member 91 is received in a cavity 92 formed at the base 46 channel 45. The opening unit 90 is provided in the middle of the receiving slots 83. That is, the opening unit 90 separates each receiving slot 83 into two slot parts 83a, 83b. The exhaust member 91 is disposed between the two engaging parts 83a, 83b. The width of the exhaust member 91 corresponds to the width of the exhaust section 71, 76 of each first and second locking element 64, 65, respectively. The width of each of the locking parts 83a, 83b corresponds to the width of each of the corresponding parts of the locking section 70a, 70b, 75a, 75b of the first and the second locking element 64, 65.
[090] The exhaust member 91 is mounted oscillatingly in the cavity 92, that is, it is articulated at one end. The exhaust member 91 is oscillating between a retracted and an operational position and is partially in its retracted position. In the retracted position, the exhaust member 91 is retracted in the cavity 92. In the operational position, the exhaust member is arranged in a direction outside the cavity 92. That is, the exhaust member 91 is displaced towards and / or from the base 46 of channel 45 and arranged to drive the first and second locking elements 64, 65 from a locking condition, in which one of the locking elements 64, 65 is received in one of the receiving locks 83, and a disengaged condition, in which the locking elements 64, 65 are pushed out of the receiving fittings 83.
[091] The exhaust member 91 has an exhaust face 93, which is ejected from cavity 92. On the other side of the exhaust member 91 is a button 94. The button 94, acting as an extended user input element through a hole in the cutting guide 40. The button 94 protrudes from an external side of the cutting guide 40. Therefore, the button is accessible when the cutting guide 40 is slidably mounted to the handle part 30. Button 94 is provided to enable an actuation force to be applied to the exhaust member 91 to propel it to move from its retracted position to its operational position.
[092] A plurality of indentations 95 is formed on the exhaust face 93 of the exhaust member 91. The plurality of indentations 95 extends parallel to each other. The indentations 95 are aligned with each receiver socket 83 and act as aligning elements. The indentations 95 act to align the locking elements 64, 65 with the receiving fittings 83. The indentations 95 have a smaller depth than the receiving fittings 83. Therefore, the locking elements 64, 65 are able to slide out and beyond the indentations, since the cutting guide 40 is slid along the body 11 without the need for excessive force.
[093] In use, the cutting guide 40 is slidably mounted to the handle part 30 by the assembly unit 50. The mounting rail 53 on the handle part 30 is received in channel 45 on the cutting guide 40. The mounting rail 53 is slid into the channel from the open end of channel 45. Mounting edges 56 are slidably received between the mounting flanges 48 of the second mounting part 52 and the base 46 of the channel 45. Then, the mounting rail 53 is able to slide into channel 45.
[094] The first and second locking elements 64, 65 protrude initially from the mounting surface 54 of the mounting rail 53. That is, the locking sections 70, 75 and exhaust sections 71, 76 of the locking elements 64 , 65 extend from opening 63. The first and second pusher members 81, 82 of the pusher unit 80 act on the first and second locking elements 64, 65 to predispose locking elements 64, 65 to extend from opening 63. Since the mounting rail 53 is slid in channel 45, the base 46 of the channel 45 overlaps the mounting surface 54 of the mounting rail 53. Therefore, the base 46 of the channel 45 acts on the first and second locking element 64, 65 to propel them to retract in a path towards opening 63. That is, the first and second locking elements 64, 65 are in their detached condition, but are predisposed in the opposite direction to the base 46 of channel 45. Sections d and locking 70, 75 of each of the first and second locking elements 64, 65 abut against the base of the channel 46. The exhaust section 71, 76 of each of the first and second locking elements 64, 65 is received in the cavity 92 at the base 46 of the channel 45. It will be understood that the exhaust member 91 of the opening unit 90 is initially arranged in its retracted position. Therefore, the exhaust member 91 does not act on the first and the second locking elements 64, 65 at this stage ...
[095] Once the cutting guide 40 is slid along the handle part 30, the first and second locking elements 64, 65 slide along the base of the channel 45 until the first locking element 64 reaches the first receiver socket 83a. The first locking element 64 is then moved beyond the first receiver socket 83a. At this stage, the first pusher member 81 predisposes the first locking element 64 to slide into the receiving socket 83. The first locking element 64 moves from its detached condition to its lockable condition. In addition, the locking section 70 of the first locking element 64 is established in the first receiver socket 83a. The converging side walls 85 of the socket 83 assist in locating the first locking element 64 therein.
[096] When the locking section 70 of the first locking element 64 is received at the first receiving insert 83a, the exhaust section 71 moves towards the exhaust member 91. However, the opening unit 90 is initially inclined by its retracted position and, therefore, does not prevent the locking section 70 of the first locking element 64 from being received in the first receiver socket 83a. The first locking element 64 is kept in its engaged condition, due to the action of the first pusher member 81.
[097] Therefore, the locking unit 60 prevents movement of the cutting guide 40 in relation to the body and, therefore, part of the blades 20. The head part 42 extends along the part of the blades 20. The cut 40 is then in a first discrete locking position. That is, the position of the cutting guide 40 is fixed in a first locking position in relation to the set of cutting blades to provide a cutting distance from the user's skin to allow the hairs to be cut at a desired distance.
[098] It will be understood that each of the receiving slots 83 is configured to receive a single locking element 64. Therefore, when the first locking element 64 is received in the receiving slot 83a, the second locking element 65 is retained at the base 46 of the channel 45. That is, the base of the channel 46 adjacent to the first receiver socket 83a acts as a receiving edge 84. The locking section 75 of the second locking element 65 leans against the receiving edge 84 and is then prevented of movement in a fit condition.
[099] Diagrammatic views of the locking unit 60 are shown in figures 10 to 12. In figure 10, the locking unit 60 is shown with the first locking element 64 received in the first receiver socket 83a. The second locking element 65 is established in opposition to the first receiving edge 84. Then, it will be understood that the movement of the cutting guide 40 is restricted.
[0100] To adjust the position of the cutting guide 40 in relation to the set of cutting blades, a user exerts a force on the button 94. The exhaust member 91 of the opening unit 90 is pushed towards the first and second elements locking element 64, 65. The exhaust face 93 is placed in contact with the exhaust section 71 of the first locking element 64 extending in the cavity 92. Then, the exhaust member 91 acts on the exhaust section 71 of the first element locking member 64 to propel the first locking member 64 to move towards its detached condition. That is, the locking section 70 of the first locking element 64 is retracted from the first receiver socket 83a. When the first locking element 64 disengages from the receiving insert 83a, the cutting guide 40 is available to slide along the handle part 30. The exhaust member 91 also acts on the exhaust section 76 of the second locking element lock 65 to keep the second lock member 65 in its detached condition. That is, the first and second locking elements 64, 65 are unavailable for location in the receiving fittings, although the exhaust member 91 acts on them and prevents them from moving in a fitting condition.
[0101] Once the cutting guide 40 is slid along the handle part 30 and button 94 is pressed, the release sections 71, 76 of the first and second locking elements 64, 65 are predisposed in the opposite direction to the exhaust face 93 of the exhaust member 91. Therefore, the locking elements 64, 65 set in opposition and move beyond the indentations 95 formed on the exhaust face 93. The indentations 95 are formed to have a surface profile, so that it is not necessary for a user to exert undue force to cause the locking elements 64, 65 to slide from indentations 95. Indentations 95 act to provide tactile feedback to a user and assist him in locating the position desired for the cutting guide 40 in relation to the part of the blades 20. It will also be understood that the indentations 95 are aligned with the receptacles 83 to assist the alignment of each of the locking elements 64, 65 with the receptacles 83 .
[0102] If a user wants to move and lock the cutting guide 40 in a position along the body 11 in a single discrete position, that is, the minimum distance that the locking unit is available for locking the cutting guide 40 in relation to the body 11, the cutting guide 40 is slid along the handle part 30 from its first locking position. It will be understood that in the present provision, the distance between discrete positions is about 1 mm.
[0103] When the cutting guide 40 is disposed in its second discrete position, the user releases button 94. Then, the exhaust member 91 moves from its operational position to its retracted position in the opposite direction to the first and to the second locking element 64, 65. Then, the first and second locking element 64, 65 are propelled to move in their locking conditions. The second locking element 65 is able to establish itself in the first receiving socket 83a, and the first locking element 64 abuts against the adjacent receiving socket 84. Such a position is shown in Figure 11. Therefore, it is not necessary that the first locking element 64 move to the next receiver slot in order to lock the locking unit in a locking condition.
[0104] If a user wants to move and lock the cutting guide 40 along the body 11 by another single discrete position, then the opening unit 90 is operated by the user and the cutting guide 40 is slid along the body 11 by the required distance. Then, the opening unit 90 is opened. Then, the first locking element 64 is able to be established in a second receiving slot 83b, and the second locking element abuts against the adjacent receiving edge 84. Such a position was shown in Figure 12.
[0105] It will be understood that the cutting guide 40 is able to be positioned and locked in a number of positions due to the plurality of receptacles 83 formed in the cutting guide. With the arrangement described above, it will be understood that the cutting guide 40 can be moved by more than one discrete position each time the opening unit 90 is operated.
[0106] In Figures 13 to 15, only one locking unit 100 is shown with a single locking element 101. The arrangement shown in Figures 13 to 15 is shown for illustrative purposes only. In this arrangement, receiver fittings 102 are provided with the same layout and spacing as the receiver fittings in the description above. Receiving edges 103 are formed adjacent to each receiving groove 102. It will be understood that, in this arrangement, the cutting guide can only be arranged in a locking condition when the locking element 101 is aligned with one of the grooves 102. Therefore , the distance between locking positions is equal to a distance between the center of each fitting, as shown in Figures 13 to 15. On the contrary, with the arrangement shown in Figures 10 to 12, the distance between locking positions is equal to half of a distance between the center of each slot 102. Therefore, the aforementioned arrangement with two locking elements provides twice the number of discrete locking positions for a defined number of fittings compared to an arrangement with a single locking element. Therefore, the distance between the locking positions can be reduced by half. In addition, the rigidity of a locking unit can be maximized by allowing the fittings and locking elements to be maximized for a defined distance between locking positions.
[0107] Although in the embodiments described above, the first and second locking elements are arranged adjacent to each other, it will be understood that in an alternative arrangement, the first and second locking elements can be spaced apart. Now, referring to Figures 16 and 17, the locking unit 110 of another embodiment of a hair clipper is shown. Generally, the hair trimmer of this embodiment is the same as the hair trimmer described above, and a detailed description of the hair trimmer will also be omitted here.
[0108] The locking unit 110 shown in Figures 16 and 17 has a first locking element 111 and a second locking element 112. The first and second locking elements 112 are spaced apart from each other twice the width of one exclusive locking element. Alternatively, it will be understood that the first and second locking elements can be spaced apart, by a multiple of twice the width of an exclusive locking element. This arrangement is provided to ensure that one of the locking elements is in a detached position when the other locking element is received.
[0109] It will be understood that when the cutting guide is moved to a single discrete position along the body of the device, the second locking element is attached to a receiver slot different from the receiver slot in which the first element lock was received. However, it will be understood that the first locking element is established in opposition to one of the receiving edges. An advantage of this arrangement is that the first and second locking elements are spaced apart, and do not slide against each other. Therefore, if one of the locking elements is prevented from moving in a locking condition, it will not act on the other locking element, which will still be able to function.
[0110] Although in the embodiments described above, the first part of the locking with the locking elements is arranged on the body and the second part of the locking with the receiving inserts is arranged on the cutting guide, it will be understood that in an alternative arrangement , the first part of the lock may be arranged on the cutting guide with the second part of the lock arranged on the body.
[0111] Although in the embodiments described above, the opening unit is provided to enable the locking elements to detach from the locking units, it will be understood that in an alternative arrangement the opening unit can be omitted. In such an arrangement, the lateral force acting on the locking element, received in the corresponding slot due to the user pushing the cutting guide to slide in relation to the device body, is sufficient to drive the locking element in a detached condition. This can be achieved by providing receiver fittings with angled side walls and / or a shallow depth.
[0112] Although in the above embodiments, the locking unit is provided with the first and the second locking elements, it will be understood that the arrangement is not limited to this. For example, the locking unit can be provided with a third locking element. In such an arrangement, the third locking element is arranged to settle in one of the receiving grooves when one of the first or second locking element settles in the or other receiver grooves. Similarly, in another arrangement, the locking unit is provided with a third locking element and a fourth locking element. In such an arrangement, the third locking element is arranged to be located in one of the receiving fittings when the first locking element is established in one or the other of the receiving fittings and the fourth locking element is arranged to be located in one of the receiving grooves when the second locking element is established in the other one of the receiving grooves.
[0113] It will be appreciated that the term "comprising" does not exclude other elements or stages and that the indefinite article "one" or "one" does not exclude a plurality. An exclusive processor can fulfill the functions of several items mentioned in the claims. The mere fact that certain measures are mentioned in different mutually dependent claims does not indicate that a combination of these measures cannot be used to an advantage. Any reference signs in the claims should not be construed as limiting the scope of the claims.
[0114] Although the claims have been formulated in this application for particular combinations of features, it should be understood that the scope of the description of the present invention also includes any new features or any new combinations of features described here, either explicitly or implicitly, or any generalizations arising from these, whether or not related to the same invention as presently claimed in any claim and whether or not all or any of the same technical problems as the main invention is mitigated. Applicants hereby notify that new claims may be made for such characteristics and / or combinations of characteristics during the process of this application or any additional application derived therefrom.
