Description

FIELD OF TECHNOLOGY

The present disclosure relates to a comb for a hair cutter.

BACKGROUND OF THE INVENTION

Hair clippers often include a comb mounted on the hair clipper. The comb comprises a plurality of comb teeth which are configured to guide the hair towards the cutting blades of the hair cutter.

Some hair clippers are designed to collect hair that has been cut off by the cutting blades of the hair clipper to prevent hair from spilling out of the hair clipper while cutting and creating a mess.

DISCLOSURE OF THE INVENTION

In accordance with one aspect of the present disclosure, there is provided a comb for a hair clipper, the comb comprising:

the first part of the comb, defining the surface of the comb, necessary to hold on the skin of the user;

the second part of the comb, containing a plurality of teeth of the comb protruding from the first part of the comb in the first direction, and the first direction has a component in the direction perpendicular to the surface of the comb, in which the plurality of teeth of the comb are spaced apart from each other in the second direction, while the second direction is parallel to the surface of the comb ; And

a third part of the comb, containing one or more additional teeth of the comb, passing in a third direction, and in the third direction there is a component in the direction perpendicular to the surface of the comb, in which the additional teeth of the comb are located on the same side of the surface of the comb as the teeth of the comb, and in in which the additional comb teeth extend farther forward than the additional comb teeth in a direction perpendicular to the first and second directions, e.g., in the hair cutting direction, and/or the comb teeth extend further back than the additional comb teeth in a direction perpendicular to the first and second directions .

The width of the additional teeth of the comb in the second direction may be equal to, for example, approximately equal to the width of the spaces between the teeth of the comb, for example, in the second direction. The width of the additional teeth of the comb may be equal to, for example, approximately equal to the width of the teeth of the comb. Alternatively, the width of the additional teeth of the comb may be different from the width of the teeth of the comb and/or the spaces between the teeth of the comb, for example, they may be narrower or wider.

The arrangement of the comb teeth and additional comb teeth can improve the ability of the comb to hold hair, as the comb teeth and additional comb teeth can cooperate to capture the cut hair coming out of the hair clipper without preventing the hair from passing through the second and third parts of the comb to reach the hair clipper. cutting hair.

In addition, since the additional comb teeth extend farther forward than the comb teeth and/or the comb teeth extend further back than the additional comb teeth, the manufacturability of the comb can be improved without compromising the effectiveness of the hair pick-up of the comb. In particular, the aspect ratio of the parts of the mold for forming the teeth of the comb and the additional teeth of the comb can be reduced.

The second part of the comb may be for guiding the hair towards the hair cutter when the hair cutter is moved in the direction of cutting the hair.

Additional comb teeth may be located at least partially or substantially completely between pairs of comb teeth. In other words, one or more additional teeth of the comb may be located at least partially between adjacent teeth of the comb in the second direction, or or substantially completely between them.

Positioning the additional teeth of the comb between the teeth of the comb can improve the efficiency of the hair grip of the comb by reducing the area through which cut hair can exit the hair clipper without contact with the comb.

Each of the additional comb teeth may be positioned between different pairs of comb teeth. Alternatively, two or more additional comb teeth may be positioned at least partially between the same pair of comb teeth.

Each of the additional comb teeth may be aligned, eg at least partially aligned, with one of the spaces between the plurality of comb teeth, eg in a second direction. The number of additional comb teeth may be equal to the number of spaces between the plurality of comb teeth.

The additional comb teeth may be positioned at least partially or completely in front of the comb teeth in a direction perpendicular to the first and second directions, for example in the cutting direction of the hair cutter. For example, the cross sections of the teeth of the comb and additional teeth of the comb, for example, in a plane perpendicular to the first or third direction, may not overlap in the direction perpendicular to the first and second direction.

Positioning the additional comb teeth in front of the comb teeth may allow the width of the gaps between the comb teeth and the additional comb teeth to be reduced without affecting the passage of hair through the comb to reach the hair cutting device. In addition, positioning the additional comb teeth in front of the comb teeth can further improve the manufacture of the comb. In particular, this may allow the comb teeth and additional comb teeth to be formed with different mold elements and/or at different manufacturing steps. When the additional teeth of the comb are located in front of the teeth of the comb, the third part of the comb can be provided on a component separate from the first and/or second parts of the comb, which can be connected to the first and/or second parts of the comb.

The first and third directions may be parallel. In other words, the teeth of the comb and the additional teeth of the comb may extend in directions parallel to each other. For example, the teeth of the comb may extend in a direction at an angle of less than 5 degrees or 10 degrees relative to the additional teeth of the comb.

The cross-sectional shapes of the teeth of the comb and the additional teeth of the comb, for example, in a plane perpendicular to the first or third direction, or in planes perpendicular to the first and third directions, respectively, may be substantially the same. For example, the cross-sectional shapes of the comb teeth and additional comb teeth may be triangular or wedge-shaped, increasing in thickness from the front of the comb teeth to the rear of the comb teeth, for example, in a direction perpendicular to the first and second directions, and may have sharp or rounded corners. .

When the additional comb teeth are triangular or wedge-shaped in cross section, the passage of hair through the comb to the hair cutter can be improved since the additional comb teeth can act to guide hair through the gaps between the comb teeth and the additional comb teeth.

The teeth of the comb and/or additional teeth of the comb may comprise hair lifting portions extending forward in a direction parallel to the surface of the comb. The hair lifting part may be designed to lift the hair when the comb is moved in a direction parallel to the surface of the comb, for example, in a hair cutting direction. The hair lifting portions may comprise oblique shaped elements extending forward from the teeth of the comb in a direction parallel to the surface of the comb. For example, one of the comb teeth and additional comb teeth may contain hair lifting parts, and the other of the comb teeth and additional comb teeth may not contain hair lifting parts. Alternatively, both the comb teeth and the additional comb teeth may comprise hair lifting portions.

The second part of the comb can be made in one piece with the first part of the comb. The third part of the comb can be made with the possibility of connection, for example, with the possibility of detachable connection, with the first and/or second parts of the comb. Alternatively, the third ridge part may be integral with the first and/or second ridge parts.

The additional teeth of the comb may have a tooth pitch equal to, for example approximately equal to, the tooth pitch of the comb. Alternatively, the tooth pitch of the additional comb teeth may be different, such as being smaller or larger than the tooth pitch of the comb.

The second part of the comb may further comprise a connecting bar extending across the distal ends of the teeth of the comb. The teeth of the comb may be connected to each other by a connecting bar, in an arrangement spaced apart from each other. The teeth of the comb can be connected to the first part of the comb with a connecting bar.

The minimum size of the gap between the teeth of the comb and the additional teeth of the comb, for example, between the cross-sectional shapes of the teeth of the comb and the additional teeth of the comb in a plane perpendicular to the first or third direction, can be equal to or greater than the width of the gaps between the teeth of the comb, for example, when the third part of the comb connected to the second part of the ridge. For example, the minimum gap size may be greater than or equal to 0.1 mm. The minimum gap size can be no more than 2.5 mm.

The size of the gap between the additional comb teeth and the adjacent one of the comb teeth in the second direction may be greater than or equal to 0.1 mm and may be less than or equal to 2.5 mm.

The hair cutting system may comprise a hair cutting device, comprising a plurality of hair cutting blades, and the above comb, the comb being coupleable, for example releasably, to the hair cutting device.

The hair cutter may include a cutting blade and a guard blade. The cutting blade may include a comb of cutting elements that engage with the teeth of the guard blade to cut hairs that enter between the teeth of the guard blade. The tooth pitch of the comb may be equal to, for example, approximately equal to the tooth pitch of the guard blade, which may improve the ability of the comb to guide hair towards the cutting elements and thereby improve the cutting efficiency of the hair cutting system.

The hair cutter may include a body. Blades, such as a cutting blade and a guard blade, may protrude from the distal end of the housing. The body of the hair cutter may include a hair receiving chamber adjacent to the hair cutter. The housing may include a wall opposite the teeth of the comb. The wall may extend in one direction with a component parallel to the first direction.

An opening may be provided in the wall, for example in a hair collection chamber, to receive the hair cut by the hair cutting device. The hole may be made near the blades of the hair cutter. The hole may extend from the blades in the same direction as the component in the first direction. The height of the opening in the first direction, for example the height of the opening protruding into a plane perpendicular to the first direction, may be approximately equal to or less than the length of the second part of the ridge in the first direction.

To avoid unnecessary duplication of effort and repetition of text in the description, some features are described only in relation to one or more aspects or embodiments of the invention. However, it should be understood that, when technically possible, the features described in relation to any aspect or embodiment of the invention may also be used with any other aspect or embodiment of the invention.

IMPLEMENTATION OF THE INVENTION

With reference to FIG. 1, the hair cutting system 2 according to the present disclosure comprises a hair cutting tool 10 and a comb 100.

The hair cutter 10 includes a body 12 and a plurality of blades 14. As shown, the blades 14 protrude from the distal end 12a of the body 12 of the hair cutter 10.

As shown in FIG. 2, the blades 14 include a cutting blade 15 and a guard blade 16. The cutting blade 15 includes a plurality of cutting elements 15a arranged in a ridge of cutting elements. The cutting elements cooperate with the teeth 16a of the guard blade 16 to cut hair received between the teeth 16a of the guard blade. The cutting blade 15 and the guard blade 16 define a cutting plane 18 in which the hair is cut by the hair cutting tool 10 .

When using the hair cutting system 2, the hair cutting device 10 is moved over the user's skin in the hair cutting direction 4 so that the user's hair is brought into contact with the blades 14 and is received between the teeth 16a of the guard blade. The received hair is cut at the cutting plane 18 as shown in FIG. 1.

As shown in FIG. 1 and 2, the comb 100 is configured to be connected, for example releasably, to the hair cutting tool 10. The comb 100 contains the first part 110 of the comb and the second part 120 of the comb. In the arrangement shown in FIG. 1, the comb 100 is connected to the body 12 of the hair cutter 10 on the first part 110 of the comb. In other embodiments, the comb 100 may be connected to a hair cutter on a second comb portion 120 or an additional comb portion.

The first comb portion 110 includes a comb surface 112 to be placed on the user's skin during use of the hair clipper. In some embodiments, the position of the comb surface 112 relative to the blades 14 may be selectively adjustable in order to control the length the hair is cut by the hair cutter 10.

The second comb part 120 includes a plurality of comb teeth 122 configured to lift and support the hair to guide the hair to the blades 14 of the hair clipper 10 when using the hair clipper system 2. The teeth 122 of the comb extend, for example, from the surface of the comb 112, in the first direction D1, which may be perpendicular, for example be between 80 degrees and 100 degrees relative to the cutting plane 18 defined by the blades 14 when the comb 100 is connected to the hair clipper 10. In the first direction D1 there is a component in the direction perpendicular to the surface 112 of the ridge.

The ridge teeth 122 are spaced apart across the side width of the ridge 100. More specifically, the ridge teeth 122 are spaced apart in a second direction D2, with the second direction parallel to the ridge surface 112.

As shown in Figure 1, the second part 120 of the comb can be made in one piece with the first part 110 of the comb. In other embodiments of the invention, the second part 120 of the comb can be made with the possibility of a movable and/or detachable connection with the first part 110 of the comb.

The comb 100 is connected to the hair cutter 10 such that the teeth 122 of the comb are positioned in front of the blades 14 of the hair cutter 10 in the hair cutting direction 4 .

The second ridge portion 120 further includes side walls 124. As shown in FIG. 2, the sidewalls 124 are offset from the plurality of ridge teeth 122 to either side of the ridge teeth 122, for example, in the second direction D2. The side walls 124 are at least partially aligned within the ridge teeth 122 in a fourth direction D4 having a component parallel to the ridge surface 112 and perpendicular to the second direction D2. For example, the fourth direction D4 may be parallel to the hair cutting plane 18 and/or the hair cutting direction 4.

The side walls 124 extend in the first direction D1. For example, the side walls 124 may extend a distance in the first direction D1 greater than or equal to the length of the ridge teeth 122 in the first direction D1. As shown in FIG. 1, the side walls 124 can be aligned with the teeth of the comb in the first direction D1. In other words, the side walls may overlap, eg completely overlap, with the ridge teeth 122 in the first direction.

The comb 100 may further comprise a connecting bar 126 extending across the distal ends of the teeth 122 of the comb. The comb teeth may be connected to a connecting bar 126 at the distal ends of the comb teeth. In an additional or alternative embodiment, the connecting bar 126 may be connected to the side walls 124 of the second part of the ridge 120 and may pass through the second part of the ridge 120 between the side walls. The connecting bar 126 may stiffen the teeth 122 of the comb.

The comb teeth 122 may be joined together, such as in a spaced apart arrangement, by a connecting bar 126. In some embodiments, the comb teeth 122 may be connected to the first comb portion 110 by a connecting bar 126 and sidewalls 124. In an additional or alternatively, the teeth 122 of the comb can be connected to the first part of the comb 110, for example, at the proximal ends of the teeth 122 of the comb.

The comb 100 further comprises a third part 130 of the comb. The third part 130 of the comb contains many additional teeth 132 of the comb. Additional teeth 132 of the ridge are spaced from each other along the lateral width of the ridge 100, for example, in the second direction D2. The tooth pitch of the additional comb teeth 132 may be the same as the tooth pitch of the comb teeth 122 . Alternatively, the tooth pitch of the additional comb teeth may be different, such as greater or less than the tooth pitch of the comb teeth 122 .

As shown in FIG. 2 and 3, the tooth pitch of the comb and/or additional comb teeth may be approximately equal to the tooth pitch 16a of the guard blade 16. For example, the number of teeth may vary by less than 3 teeth or less than 2 teeth across the width of the hair clipper 10. In one arrangement, the tooth pitch of the comb is approximately equal to that of the teeth 16a of the guard blade 16, and the tooth pitch of the additional teeth of the comb differs, for example, to a smaller side, from the pitch of the teeth 16a of the guard blade 16.

Additional comb teeth 132 extend, for example, between the longitudinal ends of the comb teeth, in the third direction D3. The third direction D3 has a component in the direction perpendicular to the ridge surface. The third direction D3 may be perpendicular to the cutting plane 18 defined by the blades 14 when the comb 100 is connected to the hair clipper 10, or between 80 degrees and 100 degrees relative to it, for example. In the arrangement shown in FIG. 1 and 2, the third direction D3 is parallel to the first direction D1, for example, at an angle of less than 5 degrees relative to it.

As shown in FIG. 2 and 3, the additional ridge teeth 132 extend further forward in the fourth direction D4 (perpendicular to the first and third directions D1, D3) than the ridge teeth 122. In a further or alternative embodiment, the teeth 122 of the ridge may extend further back in the fourth direction D4 than the teeth 132 of the ridge.

As shown in FIG. 2, additional ridge teeth 132 may be positioned ahead of the ridge teeth 122 in the fourth direction D4. In other words, the cross sections of the comb teeth 122 and additional comb teeth 132, for example, in a plane perpendicular to the first or third direction, as shown in FIG. 2 may not overlap in the fourth direction D4, for example, at any position along the length of the additional comb teeth 132.

Alternatively, as shown in FIG. 3, the comb teeth 122 and additional comb teeth 132 may partially overlap in the fourth direction D4.

As shown in FIG. 2, the cross section of the additional comb teeth 132 may be triangular or wedge-shaped. In other words, the width of the cross-sectional shape may be narrower in front or towards the front of the additional teeth of the comb, for example, in the fourth direction, than behind or towards the back of the additional teeth of the comb 132.

The cross-sectional shape of the comb teeth 122, for example, in a plane perpendicular to the first direction D1, may be substantially the same as the cross-sectional shape of the other teeth of the comb, for example, in a plane perpendicular to the first direction D1 or the third direction D3. Alternatively, as shown in FIG. 3, the cross-sectional shape of the comb teeth 122 may differ from the cross-sectional shape of the additional comb teeth 132.

The additional ridge teeth 132 may be aligned, eg at least partially aligned, with spaces between the ridge teeth 122, eg in the second direction D2. The width of the additional comb teeth 132, for example in the second direction D2, may be substantially equal to the width of the spaces between the teeth of the comb. Alternatively, the width of the additional comb teeth 132 may be different, for example, they may be wider or narrower than the comb teeth.

The shape and size, such as the width, of the additional comb teeth 132 can be made such that the size of the gap between the comb teeth and adjacent comb teeth in the second direction D2 is greater than or equal to 0.1 mm. The gap size can be less than or equal to 2.5 mm.

In some arrangements, the shape and size, such as the width, of the additional comb teeth 132 may be configured such that the size of the minimum gap between the comb teeth 122 and the additional comb teeth, for example, the shortest distance between a particular comb tooth and an additional comb tooth adjacent to a particular tooth comb, more than the width of the gaps between the teeth 122 of the comb or equal to it. As an additional or alternative option, the minimum gap size may be greater than or equal to 0.1 mm and/or may be less than or equal to 2.5 mm.

As shown in FIG. 2 and 3, the sidewalls 124 of the second ridge portion may extend forward from the ridge teeth 122 in the fourth direction D4, and may extend forward from the additional ridge teeth 132 in the fourth direction D4. In addition, the side walls 124 may extend backward from the ridge teeth 122 in the fourth direction D4. In some arrangements, the side walls 124 may extend from the rearmost portion of the ridge teeth 122 or further back to the most forward portion of the ridge teeth 132 or forward from it in the fourth direction D4. The width of the connecting strip 126 in the fourth direction D4 may be equal to the width of the side walls 124 in the fourth direction D4.

The hair cutting system 2 can be configured to reduce the mess caused during hair cutting by catching the hair that has been cut by the hair cutting device 10 .

When cutting the hair, some of the hair may protrude forward from the blades 14 in the direction 4 of cutting the hair. As shown in FIG. 2, the cut hairs emerging from the blades 14 may follow paths t1, t2, t3, t4, t5 having a forward component in the cutting direction 4. As shown, some of the hair that protrudes forward from the blades 14 may pass through the gaps between the comb teeth 122 and may collide with additional comb teeth 132. Hair colliding with the additional comb teeth 132 may lean back towards the hair cutter 10 which is held by the hair cutter system 2, as described below.

Some of the hairs that protrude forward may collide with or be deflected towards the side walls 124, whereby they may catch the hair or deflect the hair back towards the hair cutter 10. Likewise, some of the hair may collide with or be deflected towards the connecting bar 126, which may catch the hair or deflect the hair back towards the hair cutter 10.

In the devices shown in Fig. 1, 2, and 3, the third ridge portion 130 is integral with the second ridge portion 120. However, as shown in FIG. 4, in other arrangements, the third ridge portion 130 may be releasably connected to the first and/or second ridge portions 110, 120. As shown, the third part 130 of the comb may include a connecting part 134, made with the possibility of connection with the corresponding connecting part 127 of the second part 120 of the comb.

As shown in FIG. 4, the second comb portion 120 may further comprise hair lifting portions 128 extending forward from the comb teeth 122 in a direction parallel to the comb surface, for example forward in the hair cutting direction 4 . The hair lifting portions 128 may include obliquely shaped protrusions having pointed tips and increasing in height, for example, in a direction perpendicular to the comb surface 112 to the comb teeth 122, for example, in the direction of hair cutting. When using the hair cutting system 2, the pointed ends of the hair cutting parts 128 can move under the hair near the surface of the skin, which then rises when the comb moves forward in the hair cutting direction 4, and the hair moves up the oblique shape of the hair cutting parts 128 . Thus, the hair lifting portions 128 act to lift the hair during use of the hair cutting system so that the hair can be more easily cut by the blades 14.

In the arrangement shown in FIG. 4, the hair lift portions 128 are formed on the second comb portion 120 protruding from the comb teeth 122. However, in other embodiments, the hair lift portions may additionally or alternatively be formed on the third comb portion 130, for example, protruding from additional comb teeth 132. For example, when the additional comb teeth 132 protrude further than the comb teeth in the fourth direction, hair lifting portions may be formed on the third comb portion 130 .

In the arrangement shown in FIG. 4, the comb teeth 122 are not connected to the first comb part at the proximal ends of the comb teeth, so that a gap 115 is formed between the first comb part 110 and the comb teeth 122, for example, on the comb surface 112. The gap 115 allows the blades 14 of the hair cutter 10 to be positioned closer to the surface of the comb 112 when the comb 100 is connected to the hair cutter so that the hair can be cut to a shorter length. However, other arrangements may not provide this gap. For example, the comb teeth 122 may be connected to the first comb portion 110 at the proximal ends of the comb teeth.

With reference to FIG. 5, the hair collection chamber 17 may be formed inside the hair cutter body 12 to receive hair cut by the blades 14. An opening 20 in the hair collection chamber 17 may be formed in the front wall 13 of the hair cutter body 12. The front wall 13 is located opposite the comb teeth 122 and faces the comb teeth 122 when the comb 100 is connected to the hair cutter 10 .

As shown, the opening 20 may extend to the distal end 12a of the body 12 of the hair cutter 10 such that at least a portion of the blades 14 protrude from the body 12 through the opening 20. Alternatively, the opening 20 may be provided proximate the blades 14 of the hair cutter. hair, for example, directly near them. The opening height H1 may be large enough so that all, for example, more than 85%, more than 90% or more than 95% of the hair that is cut by the blades 14 can pass into the hair collection chamber 17.

As described above, the cut hair may initially protrude forward from the blades 14 and may be deflected back by the comb 100 towards the hair cutter 10 . Thus, the height H1 of the opening 20 can be made large enough to allow the hair deflected by the comb 100 to pass into the hair collection chamber 17 . In particular, the height H1 of the opening, for example, from the cutting plane 18, may be approximately equal to the length of the teeth 122 of the ridge or the second portion 120 of the ridge in the first direction D1.

In addition, the hair cutter 10 may include a fan or pump 6 configured to draw air through the opening 20 into the hair collection chamber 17 . The drawing of air into the hair collection chamber 17 may encourage cut hair to enter the hair collection chamber 17 . One or more ventilation openings 8 may be formed in the body 12 so that the air drawn in by the fan 6 exits the hair collection chamber 17 . Alternatively, the fan or pump 6 and vents 8 may be omitted.

In the arrangement shown in FIG. 5, a hair cutter 10 having a hair collection chamber 17 and an opening 20 is shown with a comb 100 having a plurality of additional comb teeth 132. However, the hair collection chamber 17 and opening 20 described above may be provided on any hair clipper 10 to include hair clippers for use with combs that do not have a third comb or additional comb teeth.

Those skilled in the art will appreciate that although the invention has been described by way of example with reference to one or more examples, it is not limited to the disclosed examples and that alternative examples may be constructed without departing from the scope of the invention as defined by the appended claims.
