Description
Hair cutting comb
The present invention relates to a comb for cutting hair and method of use, and in particular a comb which facilities hair to be cut at a precise length.
Background to the invention
Various apparatus and techniques for cutting and styling hair are known. The most frequently used technique is the scissor-over-comb method. This method allows a wide variety of hair styles and cuts to be achieved. However, this method also requires a high degree of skill to craft the hairstyle.
The scissors-over-comb method allows a hair stylist to cut close to the head and follow the hairline to achieve a precise cut. However, this method requires years of training to cut, shape and style the hair as desired.
Another method is the use of hair clippers with attached cutting guard. This method often results in a shaved look as the hair is cut to a uniform length. The clipper method also requires the clipper to be deactivated and the cutting guard changed each time a different length is desired. It is also difficult to cut hair to a length which does not fall within the preset lengths of the cutting guard attachments.
Summary of the invention
It is an object of an aspect of the present invention to obviate or at least mitigate the foregoing disadvantages of prior art hair cutting apparatus.

Detailed description of preferred embodiments
Figures 1A to 1G show perspective views of the hair cutting comb according to a first embodiment of the present invention.
The comb 10 comprises a comb body 12 with a handle section 14 attached at one end. The handle is sized and dimensioned to fit comfortably in a user’s hand.
The comb body 12 has a plurality of comb teeth 16 extending from a base section 12a. Each of the teeth extend from the base section 12a parallel with one another and define a predetermined gap 18 between adjacent teeth. Each tooth has the same size and shape.
The teeth 16 are arrange in an equidistance and parallel configuration with a gap 18 between adjacent teeth. The gap 18 is dimensioned to allow multiple strands of hair to move through the gap simultaneously when the comb is passed through a person’s hair. By accommodating multiple strands of hair between each tooth the resistance of passing the comb through the hair is reduced.
Figure 1D shows an end-view of the comb with each tooth 16 having a substantially triangular shaped profile, in particular each tooth has a scalene triangle profile 16a with a lower side 22 and two upper sides 24, 26. All three sides 22, 24 and 26 are of different lengths resulting in the substantially scalene triangular shape.
The lower side 22 is configured to contact a person’s neck and scalp. A first upper surface 24 is configured to contact and guide a hair cutting device to allow the hair to be cut to a predetermined length. The second upper surface 26 is configured to allow the tooth to move freely through a head of hair.
Figure 1C and 1D shows that the tooth profile is both scalene and oblique, meaning that none of the corners is a right angle and all three sides are of unequal length.
Each of the sides are flat or planar, with the sides 22, 24 and 26 meeting along corners or edges 28. It will be appreciated that the corners 28 may be rounded. Furthermore, the sides may be slightly concave or convex whilst maintaining a substantially scalene triangular profile.
Figure 1G shows the dimensions of the comb. The comb has thirty-one teeth 16. Each tooth has length “A” of 44mm. Each tooth 16 has a thickness “B” along the longitudinal axis of the comb of 1mm. The gap “C” between the teeth is 2mm to allow multiple strands of hair to be located in the gaps as the comb is passed over the head.
Each tooth 16 has a width or depth which is measured between lower side 22 and upper sides 24 and 26. The width or depth is measured transverse to the longitudinal axis of the comb or along a cross section of the tooth as shown in Figure 1G. The width or depth of each tooth has a width or depth “D” of 2mm at the base of the tooth. As the lower side 22 and upper side 24 diverge at they move away from the base section 12a, the tooth width increases to width or depth Έ” of 5mm at point “F” before the width or depth is reduced to reach tooth tip 30.
The base section 12a, handle 14 and teeth 16 may be made of any suitable material including plastic, metal and wood.
The handle may be made integral with the base section and/or teeth.
Depending on the length of the sides 22, 24 and 26 of the tooth profile, a range of tooth shapes each with a different tooth width or depth can be produced as shown in Figures 2A to 2D. Different combs may facilitate the controlled cutting of different of hair lengths ranging from one eighth of an inch to one inch.
Figures 2A to 2D shows end- views of four different combs 100, 200, 300 and 400 respectively. The teeth profile of the four combs 100, 200, 300 and 400 are different to allow different hair lengths to be cut.
Comb 100 has two cutting guide regions 110 and 120. Movement of a cutting device along guide region 110 of the surface 124a of side 124 cuts the hair to a predetermined length of one-eighth of an inch. Movement of a cutting device along guide region 120 of the surface 124a of side 124 cuts the hair at one-quarter of an inch.
Similarly, movement of the hair cutter along:
• guide region 210 of the surface 224a of comb 200 results in hair length of threeeighths of an inch.
• guide region 220 of the surface 224a of comb 200 results in hair length of one-half of an inch of hair • guide region 310 of the surface 324a of comb 300 results in hair length of fiveeighths of an inch • guide region 320 of the surface 324a of comb 300 results in hair length of threequarters of an inch • guide region 410 of the surface 424a of comb 400 results in hair length of seveneighths of an inch • guide region 420 of the surface 424a of comb 400 results in hair length of one inch.
Although the above examples describe combs having two cutting guide regions, it will be appreciated that combs may have a plurality of cutting guide regions and may provide a guide for the accurate cutting of a wide range of hair lengths. In the above examples the cutting guide regions are marked on the surface 124a, 224a, 324a and 424a. However, cutting guide regions or markings may alternatively or additionally be located on the surface which contacts the head, neck or scalp.
In use, a user such as hairstylist selects an appropriate comb 100, 200, 300, 400 from a selection depending in the desired length of hair and level of graduation.
As an example, as shown in Figure 3A, comb 100 is selected to produce a hair length of one-quarter of an inch. The hairstylist grips the handle 112 and positions the comb such that the longitudinal length of the handle and base section are substantially horizontal and the lower side 122 is in close contact with the base of the neck. The tips 130 of the teeth are pointed upwards toward to the top of the head.
The comb is moved in an upward direction to allow strands of hair to move between the gaps 118 of the comb. Any hairs that are longer than one-eighth of an inch protrude through the comb at region 110 and are exposed to the hair cutting device. Example hair cutting devices that may be used include scissors or a hair clipper.
The hair cutting device is positioned and moved along region 110 such that is contacts and follows surface 124a of side 124. This movement of the hair cutting device along surface 124a cuts any protruding hair and produces a hair length of one-eighth of an inch.
As hair stylist moves the comb to follow the hairline at the base of the neck and around the ears the side 122 contacts the scalp and a hair cutting device is repeatedly moved along region 110 on surface 124a of comb 100 to ensure that the hair length is cut to one-eighth of an inch.
As the comb is moved towards the crown of the head the hairstylist moves the cutting device within region 120 such that device cuts the hair at one quarter of inch in length.
To ensure proper blending and avoid visible lines of demarcation the hairstylist may depending on the individual hair style decide to graduate, blend or fade the hair cut by cutting the hair at a gradually longer length as the comb is moved towards the crown. The hairstylist moves the cutting device along the intersection of regions 110 and 120 such that device cuts the hair between one eighth of inch and one quarter of inch in length.
The shallow depth of the tooth at the base which gradually increases along the length of the tooth allows the hair cut to be cut in a naturally shape.
The comb has markings 150 on the surface 124a so that the boundaries of section 110 and section 120 are clearly indicated as shown in Figure 3A and 3B.
As shown in Figure 3B, comb 300 is selected to produce a hair length of five-eighth of an inch. The hairstylist grips the handle and positions the comb such that the lower side 322 is in close contact with the base of the neck. The tips 130 of the teeth are pointed upwards toward to the top of the head.
The comb is moved in an upward direction to allow strands of hair to move between the gaps 18 of the comb. Any hairs that are longer than five-eighth of an inch protrude through the comb at region 310 and are exposed to the hair cutting device. Example hair cutting devices that may be used include scissors or a hair clipper.
The hair cutting device is positioned and moved along region 310 such that it contacts and follows surface 324a of side 324. This movement of the hair cutting device along surface 324a cuts any protruding hair and produces a hair length of five-eighth of an inch.
If the hair stylist desires the cut the hair at three-quarters of an inch the cutting device is moved within region 320 such that device cuts the hair at three-quarter of inch in length.
Figure 4A shows a comb 410 comprises a comb body 412 with a handle section 414 attached at one end. The handle is sized and dimensioned to fit comfortably in a user’s hand. The handle is axial spaced apart from the teeth to ensure that the users hand gripping the handle does not interfere or hinder the movement of the teeth through the head of hair and the action of the cutting device along the comb.
The comb body 412 has a plurality of comb teeth 416 extending from a base section 412a. Each of the teeth extend from the base section 412a parallel with one another and define a predetermined gap 418 between adjacent teeth.
Figure 4B shows an end-view of the comb with each tooth having a substantially triangular shaped profile, in particular each tooth has a scalene triangle profile 416a with a lower side 422 and two upper sides 424, 426. All three sides 422, 424 and 426 are of different lengths resulting in the substantially scalene triangular shape.
The lower side 422 is configured to contact a person’s neck and scalp. A first upper surface 424 is configured to contact and guide a hair cutting device to allow the hair to be cut to a predetermined length. The second upper surface 426 is configured to allow the tooth to move freely through a head of hair.
Figures 4A and 4B shows the dimensions of the comb. The base section of the comb has a width or Depth “W” of 5mm and a height Ή” of 8mm. The base section has a triangular profile, shown best in Figure 4B and provides support and stability to the teeth 416.
Each tooth has length “A” of 44mm. Each tooth 16 has a thickness “B” along the longitudinal axis ofthe comb of 1mm. The gap “C” between the teeth is 2mm to allow multiple strands of hair to be located in the gaps as the comb is passed over the head.
Each tooth 416 has a width or depth which is measured between lower side 422 and upper sides 424 and 426. The width or depth is measured transverse to the longitudinal axis of the comb or along a cross-section of the tooth. The width or depth of each tooth has a width or depth “D” of 2mm at the base of the tooth at the interface with the base section 412a. As the lower side 422 and upper side 424 diverge at they move away from the base section 412a, the tooth width or depth increases to width or depth Έ” of 5mm at point “F” before the width or depth is reduced to reach tooth tip 430.
The base section 412a, handle 414 and teeth 416 may be made of any suitable material including plastic, metal and wood.
It is preferable that the handle, teeth and base section are integrally formed as a single unit. However, it will be appreciated that the handle, teeth and base sections may be formed as individual components and connected together.
Figures 5A show a perspective view of a hair cutting comb according to an embodiment of the present invention. The comb 500 comprises a comb body 512 with a handle section 514 attached at one end. The handle is sized and dimensioned to fit comfortably in a user’s hand. The handle 514 has a hook 514b at one end to allow the comb to hang when not in use.
The comb body 512 has a plurality of comb teeth 516 extending from a base section 512a. A thickened end section 512b laterally encloses the teeth. Each of the teeth extend from the base section 512a parallel with one another and define a predetermined gap 518 between adjacent teeth. Each tooth has the same size and shape.
The teeth 516 are arranged in an equidistance and parallel configuration with a gap 518 between adjacent teeth. The teeth 516 have a substantially wedge shape.
Each tooth 516 has a first surface (side or edge) 522 which is configured to contact a person’s head, neck and/or scalp. Each tooth 516 also has a second surface (side or edge) 524 which is configured to contact and guide a hair cutting device to allow the hair to be cut to a predetermined length. Each tooth 516 has a third surface (side or edge) 526. The third surface 526 is configured to be a leading side designed to allow the tooth to move freely through a head of hair.
The first, second and third surface form a tooth profile 516a. Each tooth 516 has a substantially triangular shaped side profile, in particular each tooth has a scalene triangle side profile 516a formed from the first (lower) surface 522 and two upper surfaces which comprise the second surface 524 and the third surface 526. All three surfaces 522, 524 and 526 are of different lengths and the second and third surfaces are inclined relative to the first surface resulting in the substantially scalene triangular shaped profile.
The tooth profile is both scalene and oblique, meaning that none of the corners is a right angle and all three surfaces are of unequal length.
Each of the surfaces 522, 524 and 526 are flat or planar with the sides meeting along corners or edges 528. However, it will be appreciated that the surface may be curved.
The comb 500 has thirty-one teeth 516. Each tooth has length of 44mm. Each tooth 516 has a thickness along the longitudinal axis of the comb of 1mm. The gap between the teeth is 2mm to allow multiple strands of hair to be located in the gaps as the comb is passed over the head.
Each tooth 516 has a depth which is measured along a cross section of the tooth between the first surface 522 and the respective second and third surfaces 524 and 526. The tooth has a first depth proximal to the base section, a second depth distal to the base section at the tip of the tooth. The tooth has a third depth at a point along the tooth length shown as point X in Figure 5A.
The second surface 524 diverges or is inclined from the first surface 522 at the tooth extends from the base section 512a, thereby changing the tooth depth. The third surface 526 converges or is inclined to the first surface 522 at the tooth extends towards the tooth tip 530, thereby changing the tooth depth.
The tooth depth gradually increases from the first depth until it reaches the intersection of the second and third surface, point X at in Figure 5A, before the tooth depth is reduced to reach tooth tip 530.
The handle section 514 is attached at one end of the comb body and it extends in the same plane or a plane parallel to the first surface 522. This allows the user to grip the comb and keep the users hand and fingers away from the teeth. The handle is also kept at a distance from the second surface to allow the cutting device to move along the second surface unhindered. The handle may be laterally offset from the plane of the teeth or the plane of first surface 522.
Figure 5B shows comb 600 which is similar to comb 500 and will be understood from the description of Figure 5A. However, in comb 600 as shown in Figure 5B, the length of the second surface (side) 624 is longer than the corresponding second surface 524 of the teeth in Figure 5A. Also, the length of the third surface (side) 626 of each tooth is shorter than the corresponding third surface 526 of the teeth in Figure 5A. The profile of the teeth in Figures 5A and 5B are different.
Depending on the relative lengths of the surfaces 622, 624 and 626 a range of tooth profile shapes each with a different tooth width or depth can be produced. This allows a range of cutting gradients or lengths to be produced. In this example the second surface 624 of the comb 600 diverges away from the first surface 622 at a smaller incline angle to the horizontal plane than the corresponding second surface 524 in comb 500 shown in Figure 5A.
As a result, when a cutting device is moved along the surface of second side 624 it is in a closer position to the scalp and allows hair to be cut at a shorter length. Controlling the lengths of the sides of the scalene profile a range of cut lengths may be produced. The cuts may range from one eighth of an inch to one inch.
The teeth 516 and 616 have markings on their surfaces to act as a visual guide to indicate to the user the length that the hair will be cut to if the cutting device is moved over the surface of the second side 524 and 624 adjacent to that marking. In these examples the markings are located on the first side 522, 622. However, the markings may be located additionally or alternatively on the second sider 524 and 624. Throughout the specification, unless the context demands otherwise, the terms 'comprise' or 'include', or variations such as 'comprises' or 'comprising', 'includes' or 'including' will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers.
Furthermore, relative terms such as”, “lower”, “upper, “up”, “down”, above, below and the like are used herein to indicate directions and locations as they apply to the appended drawings and will not be construed as limiting the invention and features thereof to particular arrangements or orientations.
The invention provides a hair comb comprising a base section and a plurality of teeth extending from the base section. Each tooth has a polygonal profile shape and each side of the polygonal profile has a different length. At least two sides of the polygonal profile extend from the base section.
The invention may provide a robust, reliable and efficient hair comb suitable for cutting hair to variety of lengths.
Although in some of the above examples, the base section has a triangular profile, it will be appreciated that other profile shapes may be used. The profile shape may be selected to provide structural and stability support to the teeth and handle. The profile shape may be selected to provide enable the comb to pass through the hair with little resistance and/or promote separation of the hair strands.
An alternative embodiment of the invention may comprise the teeth profile having a polygon shape profile which is not triangular. It will be appreciated that other tooth profile shapes may be used. The profile shape may be selected to provide support to the cutting device. The profile shape may be selected to contact the scalp and enable the comb to pass through the hair with little resistance and/or promote separation of the hair strands.
The foregoing description of the invention has been presented for the purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise form disclosed. The described embodiments were chosen and described in order to best explain the principles of the invention and its practical application to thereby enable others skilled in the art to best utilise the invention in various embodiments and with various modifications as are suited to the particular use contemplated. Therefore, further modifications or improvements may be incorporated without departing from the scope of the invention herein intended.
