COMB FOR A BRUSH FOR GROOMING ANIMAL FUR

Abstract

Disclosed is a comb having a lamellar body and including, along a toothed edge, teeth able to penetrate the coat of hair. The comb eliminates injuries caused to the animal by sharp teeth, eliminating fur damage while also improving the treatment of the hair coat and to improve brushing performance by adapting to the hair coat of each animal, in each season. To this end, the teeth of the two sets of teeth A and B, which are positioned one on each side of the mid plane P of the body and the teeth of which sets are intercalated with one another, have anti-injury roundings at the tips and over part of the length of the edge corners leading from these tips and are delimited between a flat external face and a curved extreme internal face, the tooth set B being finer and provided with shorter teeth.

[0027] FIG. 10 is a partial view with a cross-section of the comb showing, on a very enlarged scale, the action of the sets of teeth on the coat of hair of an animal;

[0028] FIGS. 11 and 12 are views similar to FIGS. 9 and 10, but during a brushing operation with the secondary set of teeth positioned at the front.

[0029] Generally and as shown in FIG. 1, the comb 1 according to the invention is comprised of a lamellar body 2 provided with in its heel means for fastening 3 or 4 on a head 5 with handle 6, visible in FIG. 9.

[0030] In the embodiment of the invention shown in the figures, the lamellar body 2 comprises a toothed edge formed by two sets of teeth, respectively, the main set A and secondary set B, positioned on either side of the mid plane P of the comb (FIGS. 4 and 5) and comprised of teeth 7 and 8. The teeth 7 of the main set of teeth A are intercalated with the teeth 8 of the secondary set of teeth B and are delimited, as they are, between a flat external face, respectively 9a and 9b, corresponding to the faces of the lamellar body, and a curved internal face, respectively 10a and 10b, formed at the end of the teeth. The faces 9a and 9b, 10a and 10b and the faces of toothgaps 11 are smooth and without asperities in such a way as to facilitate the sliding of the hairs against them.

[0031] This is obtained all the more so easily in that each lamellar body 2 with its comb with a double set of teeth A and B is obtained by moulding a material, such as metal or a plastic material, having a good sliding coefficient and a flexibility for avoiding tension in the coat of hair. In a manufacturing alternative the body and the combs are obtained by 3D printing.

[0032] In the embodiment of FIG. 4, which shows a cross-section of a tooth 7 of the main set of teeth A, the internal face 10a of this tooth 7 is convex, while, in FIG. 5, the face 10b of a tooth 8 of the secondary set of teeth B is concave. These figures also show that the teeth 7 of the main set of teeth A are longer than those 8 of the secondary set of teeth B by a value V.

[0033] In this embodiment, the difference between the lengths of the sets of teeth A and B is about from 5 to 20% of the length of the longest tooth 7 of the set of teeth A. These dimensions can vary according to the targeted action sought.

[0034] Moreover, the length of the sets of teeth A and B is between half and two-fifths of the width of the lamellar body 2, according to the means of fastening of this lamellar body onto the brush body 5, namely by screws passing through the holes 3 made in the body 2 or by the engagement of a T-shaped tenon 4 of the body 2 in a groove of the brush body. These proportions can changer according to the type of brush used.

[0035] FIG. 2 which lists the sections S1 to S5 obtained by the cross-sections 1 to 5 of FIG. 1, shows that the cross-section of each one of the teeth 7 and 8 of the two sets of teeth A and B pass from a circular shape (in S1 and S2) to a square shape then rectangular with rounded edges (in S3 and S4), then not rounded (in S5) by moving from the rounded tip of each tooth towards its connection to the lamellar body 2. This characterises the presence of rounded ends then rounded edges extending over a portion of the length of the teeth, in order to not favour the pulling off or the sectioning of the hairs.

[0036] The junction of the teeth with the lamellar body 2 is without rounded edges, as shown in S5. This organisation forms a sloped plate Z which makes it possible to store the dead hairs combed. This zone Z also favours the cleaning and the storing of the dead hairs, by as such releasing the sets of teeth for optimum brushing.

[0037] FIG. 2 also shows that the cross-section of each one of the teeth 8 of the secondary set of teeth B is smaller than that of the teeth 7 of the main set of teeth A.

[0038] FIGS. 6 and 7 show, through their enlarged sections S6 and S7 of the toothgap sets of teeth, respectively B and A, that the bottom of this toothgap has a section that varies, by moving transversally in the thickness of the comb, for example from the small teeth 8 towards the large teeth 7, from the semi-circular shape 12, of FIG. 6, to the shape of an arc of a circle 13 abutting against the flank of the tooth 8, as shown in FIG. 7. Each toothgap as such delimits a transversal corridor, collecting the hairs of the brushed fur by directing them towards the straight and flat lateral faces 11 at the base of the teeth favouring the removal of the dead hairs, dead skin, dust and spikelets, by smoothing these hairs.

[0039] As shown in FIGS. 1, 3 and 6 to 8, when the comb extends longitudinally beyond the ends of the sets of teeth A and B, it comprises two framing fingers 15 which each have a length less than those of the teeth 7 and 8 and which are provided with a rounded tip 16 and rounded edges 17. With the same purpose of not giving the comb the possibility of injuring the skin of the animal, the teeth 7a and 8a which are positioned against the framing fingers 15 have a length which decreases when moving towards these framing fingers.

[0040] Note that in order to best adapt to the size of the animals that can be brushed and groomed, for example from the Chihuahua to the Saint Bernard, the comb is provided in several sizes which are differentiated by the width of the sets of teeth and the length of the teeth. In addition, as the animals do not have the same density of fur, the combs are provided with different configurations that allow them to be used for different animals by adapting to thickness, and to the length of their coat of hair.

[0041] The description, which precedes, differentiates the sets of teeth A and B in a general way by adding “main” and “secondary” to them, purpose in the embodiment that follows these same sets of teeth are defined by their user, namely, “for thick fur” for the set of teeth A and “for fine fur” for the set of teeth B. As the coat of hair of the same animal can, according to the seasons, switch from thick fur to a more aerated fur, and inversely, the user of the brush can take advantage of the removability of the comb to turn it over on the head 5 of the brush and come into contact with the hairs by the set of teeth that best corresponds to the density of the fur.

[0042] FIG. 9 shows a brush wherein the comb 2 is positioned in such a way that it is the main set of teeth A “for thick fur” that is in front and comes into contact with the hairs 20 when the brush is displaced according to the arrow 21, with the set of teeth B therefore being at the rear. With FIG. 10, it shows that the comb with its two sets of teeth, the main set of teeth positioned in front, is engaged without difficulty into the coat of hair and that its contact with the skin 22 is carried out via the rounded ends of its set of teeth 7, therefore without being able to injure the skin.

[0043] During the brushing movement the hairs 20 pass in the corridors of the toothgaps and which pushed then against the lateral faces 11 of the teeth 8 of the set of teeth B, faces which remove from the fur dead hairs, waste, dust and spikelets, by storing them on the zones Z, while still providing by the faces 11 a gentle smoothing of these hairs, as soon as they are released by the set of teeth A.

[0044] In FIG. 11, the comb is shown on the head 5 of the brush in such a way that it is the secondary set of teeth B that is in the front and comes first against the hairs 20, when the handle is pulled according to the arrow 21.

[0045] FIG. 12 shows that the brush is held manually with an inclination of the handle in such a way that the two sets of teeth A and B are in contact with the skin 22, in order to distribute the force of contact over the skin without risking injuring to it thanks to the rounded ends. As the pressure of the teeth on the skin is distributed over two rows the brushing feeling is gentler for the animal.

[0046] This position that brings the sets of teeth close to the skin in order to optimise brushing is specific for a coat of hair with fine hair and is therefore recommended for “sensitive” zones and zones with few hairs, such as the ears, paws, the neck and/or short hairs.

[0047] During the brushing movement the hairs 20 pass in the corridors of the toothgaps and which pushes them against the lateral faces 11 of the teeth 7 of the set of teeth A, faces that remove from the fur dead hairs, waste, dust and spikelets, while still providing a gentle smoothing of these hairs, as soon as they are released by the set of teeth B. As such, the main set of teeth A, positioned at the rear, has a “reinforcing” function of the brushing, and, with its convex shape and its sloped plates Z, groups together and retains the dead hairs, dead skin, dandruff, dust and spikelets, which can be extracted when the brush is removed from the coat of hair.
