DETAILED DESCRIPTION
[0039] With reference to
[0040] The hair cutting appliance 2 comprises a body 4 including a grip portion 6 configured to be held by user when the hair cutting system is in use. The hair cutting appliance 2 comprises one or more cutting blades 10, which may protrude from the body 4 of the hair cutting appliance for cutting hair.
[0041] The hair cutting appliance 2 further comprises an electric motor 8. The electric motor 8 drives the cutting blades 10, e.g. to perform a reciprocating, oscillating or rotating motion, in order to cut hair.
[0042] The comb 100 comprises a first comb part 110, a second comb part 120 and a comb connection part 130, which connects the first and second comb parts 110, 120 together. The comb connection part 130 defines a comb surface 132. In some embodiments the comb surface might be formed by the skin facing side of the connection comb teeth 136. In use of the hair cutting system 2, the comb surface 132 is rested against the user's skin and the hair cutting system 2 is moved in a cutting direction C to cut the user's hair. It is to be noted that the comb surface 132 may be the only skin contact surface of the comb. Alternatively the skin contact surface might be formed by the connection comb teeth 136 and at least part of the second comb teeth 126 and/or the first comb teeth 112. More generally the skin contact surface might be formed by the comb connection portion 130, or by a combination of the comb connection portion and at least part of the second comb part 120 and/or the first comb part 110.
[0043] The first comb part 110 comprises a plurality of first comb teeth 112, which are arranged to guide hair towards the cutting blades 10 to be cut. The first comb teeth 112 each extend in the cutting direction C and are spaced laterally across the first comb part 120, e.g. in a direction perpendicular to the cutting direction C, in order to guide the hair towards the cutting blades across the lateral width of the hair cutting appliance 2.
[0044] The first comb teeth 112 may comprise respective ramp portions 112a that are arranged to lift hair away from the skin in order to position the hair in an appropriate position and orientation to be cut by the cutting blades 10. The first comb teeth 112 may further comprise respective extension portions 112b to continue supporting the hair after it has been lifted away from the skin, e.g. whilst it is being cut. The extension portions extend away from the comb surface 132 in a direction with a component perpendicular to the cutting direction C and the comb surface 132.
[0045] The first comb part 110, e.g. surfaces of the first comb teeth 112, defines a first comb surface 124, which forms a forward extension to the comb surface 132, e.g. forward of the cutting blades 10 in the cutting direction C.
[0046] The second comb part 120 comprises a coupling portion 122 configured to couple the comb 100 to the hair cutting appliance 2. The second comb part 120 defines a second comb surface 124 which forms a rearward extension to the comb surface 132, e.g. rearward of the cutting blades 10 in the cutting direction C.
[0047] The second comb part 120 may comprises a plurality of second comb teeth 126. The second comb teeth may be aligned, e.g. substantially aligned, with the first comb teeth 112, so that the second comb teeth 126 are arranged to continue guiding hair from the first comb teeth 112 past the cutting blades 10, as the hair cutting system 2 is moved in the cutting direction C.
[0048] The comb connection part 130 may comprise a plurality of protrusions or ribs extending in the cutting direction C to form a plurality of third comb teeth 132. The third comb teeth may be aligned, e.g. substantially aligned, with the first and second comb teeth, so that the third comb teeth 132 are arranged to guide hair from the first comb teeth 122 towards the cutting blades 10 and the second comb teeth 126. In some arrangements, the comb connection part 130 may be discontinuous in a lateral direction of the hair cutting system, e.g. perpendicular to the cutting direction C, to form the plurality of third comb teeth 132.
[0049] With reference to
[0050] As depicted, the comb 100 comprises side walls 140 provided on lateral sides of the comb 100. The side walls 140 are formed by side wall parts, 118, 128, 138 of the first comb part 110, the second comb part 120 and the comb connection part 130 respectively. As depicted in
[0051] As depicted in
[0052] The second comb part 120, e.g. the coupling portion 122, and/or or the hair cutting appliance 2 may be configured such that the position of the hair cutting appliance 2 relative to the comb connection part 130 is adjustable in order to adjust the distance between the cutting blades 10 and the comb surface 132. In the arrangement depicted, the hair cutting appliance 2 comprises a cutting height adjustment mechanism 9 that adjusts the position of the hair cutting appliance 2 relative to the coupling portion 122, e.g. by changing the position on the coupling portion 122 at which the hair cutting appliance is coupled, in order to change the distance between the cutting blades 10 and the comb surface 132.
[0053] Additionally or alternatively, the hair cutting appliance 2 may be configured such that the position of the cutting blades 10 is movable relative to the body 4 of hair cutting apparatus 2 so that the distance between the cutting blades 10 and the comb surface 132 can be adjusted, e.g. without the body 4 of the hair cutting apparatus 2 being moved relative to the comb connection part 130.
[0054] The first comb part 110 and/or the second comb part 120 may be at least partially formed from a plastic material. In particular, the first comb teeth 122 may be formed from the plastic material. Additionally or alternatively, a portion of the first comb part forming the first comb surface 114 and/or the portion of the second comb parts forming the second comb surface 124 may be formed from the plastics material.
[0055] In other words, parts of the first and second comb parts that contact the skin and/or hair of the user during use of the hair cutting system 1 may be formed from the plastics material.
[0056] Forming the first and second comb parts 110, 120 at least partially from the plastics material may improve user comfort when using the hair cutting system 1. In some arrangements, the first and second comb parts 110, 120 may be formed entirely of the plastics material.
[0057] The comb connection part 130 may be at least partially formed from metal, such as aluminium, steel, stainless steel or titanium or a combination of different metals. In particular, a portion of the comb connection part 130 aligned with the cutting blades 10, e.g. in the cutting direction C, may be formed from metal.
[0058] By forming the comb connection part 130 at least partially from metal, the structural strength of the comb connection part 130 may be increased for a given thickness of the comb connection part, compared to a comb connection part made from the plastic material. The comb connection part 130 can therefore be made thinner without reducing the strength of the comb connection part, e.g. compared to a comb comprising a comb connection part made from the plastics material.
[0059] The length of hair that has been cut by the hair cutting system depends on the distance between the comb surface and the cutting blade 10. By forming the connecting part 130 from metal, the minimum thickness of hair that can be cut by the hair cutting system can be reduced, because the cutting blades 10 can be positioned closer to the comb surface.
[0060] In the arrangement depicted in
[0061] Returning to
[0062] The first comb part 110 and/or the second comb part 120 may be formed on to the comb connection part 130, e.g. onto the comb connection elements 136. For example, the first and/or second comb parts 110, 120 may be overmoulded on to the comb connection part 130. Alternatively, the comb connection part 130, e.g. the comb connecting elements 136, may be inserted into the first and/or second comb parts, e.g. after the first and/or second comb parts have been formed. In this case, the comb connection part 130 may be adhered to the first and second comb parts 110, 120 or attached using any other suitable process.
[0063] The comb surface 132 may be substantially covered with the plastics material. Alternatively, at least a portion of the comb surface 132 may be free of plastics material, e.g. so that the thickness of the comb connection part 130, and hence, the length of cut hair, can be minimized.
[0064] In the arrangement depicted in
[0065] With reference to
[0066] The comb connection part 430 consists of side wall portions 436 for forming part of a sidewall 440 of the previously proposed comb. The side wall 440 is similar to the sidewall 140 of the comb 100 depicted in
[0067] The comb connection part 430 of the previously proposed comb 400 differs from the comb connection part 130 of the comb 100, in that the comb connection part 430 does not comprise comb connecting elements between the side wall portions 432. Instead, a gap 434 is provided in the cutting direction C between the first and second teeth 412, 422 in a central area of the comb 400. The gap 434 may be aligned with the cutting blades of a hair cutting appliance coupled to the comb 400.
[0068] In the previously proposed comb 400, having a gap 434 aligned with the cutting blades of the hair cutting appliance allows the cutting length of hair to be minimized, because the hair cutting appliance can be positioned at a comb surface 432 of the comb without clashing with the comb connection part 430.
[0069] As depicted, the first comb part 410 of the previously proposed comb 400 comprises a comb connecting bar 414. Because the first comb teeth 412 are not connected to the second comb teeth 422 by the comb connection part 430, each of the first comb teeth 412 is coupled to the comb connecting bar 414 at distal ends 412a of the first comb teeth. The comb connecting bar 414 thereby supports the first comb teeth 412 relative to the rest of the comb 400.
[0070] When the length of hair being cut by a hair cutting system comprising the previously proposed comb 400, exceeds a certain length, e.g. such that the hair being cut does not pass under the connecting bar 414, hair can stack up and become clogged between the first comb teeth 412 underneath the connecting bar 414.
[0071] With reference to
[0072] In the arrangement shown, the comb connecting bar 150 is coupled to distal ends of the first comb teeth formed by the side wall portions 118 of the first comb part 110. However, in other arrangements, different ones of the first comb teeth 112 may be connected to the comb connecting bar 150.
[0073] The comb teeth arranged between the side wall portions 118 may not be coupled to the comb connecting bar 150. Distal ends of the first comb teeth not connected to the comb connecting bar 150 may be spaced apart from the comb connecting bar 150, such that a hair clearance 152 is provided between the distal ends of the first comb teeth and the comb connecting bar 150.
[0074] As shown, the hair clearance 152 may extend in a direction with a component perpendicular to the cutting direction C of the hair cutting appliance 2. The hair clearance may extend in the direction in which the first comb teeth extend, e.g. the direction in which the extension portions 112b of the first comb teeth extend at their distal ends 112c.
[0075] Providing the hair clearance 152 between the first comb teeth 112 and the comb connection bar 150 allows hair that has been cut by the hair cutting appliance 2 to fall out of the comb 100 because it is not confined between the first comb teeth 112 and the comb connecting bar 150.
[0076] It will be appreciated by those skilled in the art that although the invention has been described by way of example, with reference to one or more exemplary examples, it is not limited to the disclosed examples and that alternative examples could be constructed without departing from the scope of the invention as defined by the appended claims.
