DETAILED DESCRIPTION OF THE INVENTION

[0034] In order that those skilled in the art better understand the invention to clearly define the claimed scope of the invention, the invention will be described below in detail with reference to some particular embodiments of the invention.

[0035] As shown in FIGS. 1 to 8, a rubber assembly comprises comb teeth 1 and a rubber 2, and the comb teeth 1 are directly or indirectly fitted on the rubber 2 to form the rubber assembly. A plurality of raised columns 3 are also arranged at a back side of the rubber 2, and the raised columns 3 are arranged independently of each other and spacedly. As shown in FIGS. 1 and 2, the raised columns 3 have a certain interstitial space among each other so that the overall thickness of the rubber assembly in use is not increased due to the arrangement of the raised columns 3. In fact, excessively dense raised columns 3 cause such problem to some extent, thus the thickness of the rubber 2 and the parameters and distribution density of the raised columns 3 can be set correspondingly according to actual conditions. The raised columns 3 are internally provided with tooth holes 4 in which the comb teeth 1 are arranged and cavities 31 for accommodating the comb teeth 1, the tooth holes 4 extend through a front side of the rubber 2, and the cavities 31 are sealed except for the tooth holes 4; that is, a cavity having an opening (i.e. the tooth hole 4) at one end is formed in the raised column 3. Accordingly, the comb teeth 1 are passed through the tooth holes 4 from the front side of the rubber 2 and into the cavities 31, so that the comb teeth 1 are fixed on the rubber 2.

[0036] The comb teeth 1 is made of a soft material, a hook 5 is arranged at one end of the comb tooth 1, and the tooth holes 4 are internally provided with clamping pieces 6 which can be fitted into the cavities 31 and fixed; for example, the length of the cavities 31 is greater than the diameter of the tooth holes 4, so that the hooks 5 are tightly fitted into the cavities 31 and hook the clamping pieces 6; and of course, the clamping pieces 6 are not limited in a cylindrical shape, a cubic shape or other shapes, and all relevant shapes that can be independently fitted into the cavities 31 are optional. The diameter of the tooth holes 4 is equal to or smaller than the inner diameter of the cavities 31. Since the rubber 2 is made of a flexible material and has a certain elasticity, the diameter of the tooth holes 4 of the above two specifications can allow the arrangement of the clamping pieces 6 in the cavities 31. Most preferably, the inner diameter of the cavities 31 matches the outer diameter of the comb teeth 1, so that inner walls of the cavities 31 can exert a force on the comb teeth 1 after the comb teeth 1 are bent and fitted into the cavities 31, thus imparting the comb teeth with a good fixing effect. Theoretically, a smaller inner diameter of the cavities 31 enables the comb teeth 1 to have a better fixing effect, but increases the difficulty of fitting the hooks 5 of the comb teeth 1 into the cavities 31, while larger cavities 31 can reduce the difficulty of fitting the hooks 5 of the comb teeth 1 into the cavities 31, but weaken the fixing effect of the comb teeth 1 in the cavities 31, so their relative specifications need to be moderately set. In addition, the hooks 5 can hook the clamping pieces 6 followed by being together inserted into the cavities 31, and the manner in which the comb teeth 1 and the rubber 2 are assembled is very easy to achieve.

[0037] For the material of the comb teeth 1, the comb teeth of the prior art are mainly manufactured by injection molding of plastic, and therefore are relatively hard and prone to hair tangling; and in some patented technologies, the comb teeth are provided with spherical or spheroidal structures to alleviate this problem, which has not been fundamentally solved. Therefore, a softer material (compared with a traditional plastic material) is used to make the comb teeth, which can fundamentally solve this problem. The actual material of the comb teeth can have many options after meeting the above requirement on flexibility. Preferably, the comb teeth 1 are made of nylon, more specifically, nylon yarn. The comb tooth 1 made of nylon yarn has one end bent to form the hook 5 and the other end formed as a comb tooth head. Compared with the comb teeth formed by injection molding and then engaged on a rubber in a traditional connection method, the nylon comb teeth are softer, which can fundamentally overcome the problem of hair tangling easily caused by the traditional plastic injection comb teeth during use.

[0038] However, for the technical problem of how the nylon comb teeth are relatively firmly and safely fixed on the rubber, there is no effective solution in the prior art, and a possible general solution is to fix with glue. In this way, the fixing strength is not high on the one hand, the volatilization of glue brings safety problems on the other hand, and the fixing performance is obviously weakened with the passage of service time. In addition, in order to ensure a sufficient adhesive contact area, the thickness of a rubber also tends to be correspondingly increased, which greatly affects the massage effect of an air-cushion comb and therefore is not preferable. Therefore, the invention adopts a separate design scheme in which the rubber 2 with an integrally supporting function is first designed, the raised columns 3 for fixing the comb teeth 1 are then arranged at the back side of the rubber 2, and the comb teeth 1 are securely fixed in the raised columns 3 by the clamping pieces 6; hence, the fixing strength of the comb teeth is also enhanced without the use of glue, and meanwhile the thickness of the rubber 2 also does not need to be additionally increased, i.e. the above problem is solved by the raised columns 3 and the thin rubber 2 instead of a thick rubber.

[0039] Preferably, the thickness of a body portion of the rubber 2 in a cross-sectional direction gradually increases from the middle to the edge, i.e. the thickness of an intermediate portion of the rubber 2 is smaller than that of an outer edge portion thereof, which not only enables the intermediate portion that is first contacted and deformed to be the softest part so as to enhance user experience, but also can facilitate the restoration of the deformed rubber 2 by gradually increasing the elastic force. Practice shows that a rubber with a uniform thickness has a small probability of being unable to automatically restore in use, but the above design of gradual thickening from the middle to the edge can completely avoid this problem. In general, the thickness H1 of the center of the body portion of the rubber 2 (i.e. except for the outer edge for rubber fixing) is 1-3 mm, the thickness H2 of the outer edge is 2-5 mm, and the thickness is gradually increased from the center to the outer edge, but uniform thickening from the center to the edge is also not required; and of course, theoretically, stepwise thickening is also a feasible scheme (for example, the entire rubber is divided into three parts of 1.5 mm, 2 mm and 3 mm from the inside to the outside). In one embodiment, the thickness H2 of the outer edge of the rubber 2 is 3 mm, the thickness H1 of the thinnest portion of the center is 1.5 mm (although the variation in thickness is not apparently shown in related drawings, the thickness of the rubber 2 of the invention in a cross-sectional direction shown in FIGS. 3 to 9 gradually changes from the center to the edge).

[0040] Preferably, the raised columns 3 and the rubber 2 are integrally formed by injection molding. Specifically, the manufacturing process of the invention is also different from a conventional rubber manufacturing process, wherein the conventional rubber manufacturing process comprises forming comb teeth by die stamping on a rubber plate and then gluing the comb teeth to a rubber, while the invention is configured as follows: the rubber 2 is subjected to injection molding by an injection mold and then the comb teeth are embedded into the comb tooth holes by a machine, and the length of the clamping pieces 6 is greater than the diameter of the tooth holes so that the clamping pieces 6 are closely connected, thus ensuring the connection strength between the comb teeth 1 and the tooth holes 4. The tensile force of the connection strength is 1.2-1.5 kg, but the tensile force of the traditional glued comb teeth is 1.0-1.2 kg, so the connection strength of the invention is greater, and no glue is needed. Therefore, the invention is very environmentally friendly and can also ensure that the thickness of the rubber 2 is not increased which would otherwise affect the overall massage effect.

[0041] As shown in FIGS. 9 to 13, a comb comprises a comb handle 7 and a comb portion fitted thereon, wherein the comb portion is the above rubber assembly.

[0042] Preferably, the comb handle 7 comprises a placement groove 8 for placing the rubber 2, a transverse engaging slot 9 is arranged at an edge of the placement groove 8, an engaging block 10 is arranged at an outer edge of the rubber 2, the rubber 2 is mounted in the placement groove 8, and the engaging block 10 is in snap fit with the engaging slot 9 so that the center of the rubber is raised toward the front side. The thickness of the engaging block 10 is greater than that of an intermediate portion of the rubber 2.

[0043] Preferably, the engaging slot 9 and the engaging block 10 are tooth-shaped or triangular. More preferably, a surface of the engaging slot toward a back side of the comb handle is provided with a second inclined surface 12 which is toward the front side and inclined toward the center of the rubber 2, and the engaging block 10 contacts the second inclined surface 12; and a back side of the engaging block 10 is provided with a first inclined surface 11 which is outward and inclined toward the front side of the rubber 2, and the first inclined surface 11 contacts the second inclined surface 12. The engaging block 10 comprises an annular notch 13 and the step slot is cooperatively engaged with the comb handle 7.

[0044] For a traditional air-cushion comb, an air cushion or airbag structure is formed due to the expansion of a rubber, which causes the rubber to bulge in the middle relative to the edge, forming a shape similar to an ellipsoidal rubber and an ellipsoidal comb tooth surface (i.e. a curved surface on which the top of comb teeth is located).

[0045] For this reason, the placement groove 8 of the comb handle 7 of the comb of the invention is bent toward the back side of the rubber 2, and after the rubber assembly is fitted to the comb handle 7, the rubber 2 is straight in the AA direction; hence, the comb teeth 1 are also straight in this direction (as shown in FIGS. 10 and 13), so that the contact area between a comb tooth surface and hair or scalp can be increased. Meanwhile, as shown in FIGS. 10 to 13, the edges at both sides of the placement groove 8 are relatively recessed downward to form low points 82 at both sides, and its both ends in the straight direction are respectively formed as flat ends 81. In other words, a placement groove 8 of a traditional comb substantially takes the shape of an ellipse on the same plane, while for the placement groove 8 of the comb handle 7 of the invention, the above placement groove is unchanged in its major axis direction, but bent downward in its minor axis direction to form the placement groove 8 shown in FIGS. 10 to 13. The placement groove 8 enables the rubber to achieve the effect of no sagging in a smooth state by downwardly rolling the edges of the rubber 2 in the minor axis direction, and the rubber can also provide a good restoring force when pressed downward. Of course, the above scheme in which the major axis is unchanged and the minor axis is rolled downward is also not fixed, and direction exchange or appropriate rotation may also be an alternative embodiment.

[0046] That is to say, due to the structure of the placement groove 8 and the rubber 2, the surface of the traditional rubber 2 is substantially spherical or ellipsoidal, while the edges at both sides of the placement groove 8 of the invention are relatively recessed downward, so that the rubber 2 is arranged in the shape of a curved surface similar to the shape of a curved TV after being fitted therein, i.e. the rubber is formed as follows: the rubber is divided into left and right parts by a connecting line (referred to as a straight line) between the two flat ends 81, and the left and right parts are respectively rolled downward; and more specifically, the curved surface is a trajectory formed by the continuous movement of a straight line as a generatrix in a parabolic direction in space. FIGS. 9 and 10 show a preferred embodiment. It can also be seen from the Figures that the rubber 2 of the comb is in a straight line in the direction of the generatrix on the curved surface, which is quite different from that of the traditional spherical or ellipsoidal comb; such structure can increase the contact area between the comb and scalp or hair, which also provides better overall conformability when hair is combed; and meanwhile, the combination of the curved structure with the design of a thin middle part and a thick periphery for the rubber 2 also improves the restoration effect, and since the rubber is straight in the centerline direction, the rubber 2 is stretched in the centerline direction after its intermediate portion is deformed, so that a restoring force in another direction can be provided. That is to say, the rubber of the invention has not only the restoring force generated by the compression of downwardly rolled portions at its both sides, but also the restoring force generated by the stretching of the straight central portion. In addition, although the above description and FIGS. 9 and 10 mainly describe the downward rolling in a certain direction (or the arrangement along a certain curved surface), it is very apparent that the curling direction of the rubber 2 is not limited to this direction, and any similar curling scheme (excluding traditional spherical curling) is feasible in principle.

[0047] As shown in FIGS. 9 and 14, for the comb of the prior art, the rubber is deformed and bulging after being mounted to the comb handle 7, and a transverse pressure F is generated when hair is combed, so that the contact area between the edge of the rubber and the engaging slot 9 is very small, and the rubber is not mounted firmly and is easy to fall off. In order to solve this problem, as shown in FIG. 9, a surface of the engaging slot toward a back side of the comb handle is provided with a second inclined surface 12 which is toward the front side and inclined toward the center of the rubber 2, the engaging block 10 contacts the second inclined surface 12, and the use of the inclination angle of the second inclined surface 12 can block the transverse pressure F generated by hair combing as much as possible, thereby increasing the connection strength between the engaging block and the engaging block, so that the rubber is not easy to fall off. A back side of the engaging block 10 is provided with a first inclined surface 11 which is outward and inclined toward the front side of the rubber 2, and the first inclined surface 11 contacts the second inclined surface 12. After the rubber 2 is integrally deformed, the angle of the first inclined surface 11 changes to approximate the inclination angle of the second inclined surface 12, thereby increasing the contact area between the first inclined surface 11 and the second inclined surface 12, and further improving the connection strength between the engaging block and the engaging block. The engaging block 10 comprises an annular notch 13 and the step slot is cooperatively engaged with the comb handle 7 to provide a more smooth appearance.

[0048] A method for manufacturing a comb comprises the following steps:

a comb is configured to comprise a comb handle and a rubber assembly which are detachably fitted; wherein the rubber assembly further comprises comb teeth 1 and a rubber 2; and the comb teeth 1 are directly or indirectly fitted on the rubber 2 to form the rubber assembly;
a plurality of raised columns 3 are arranged at a back side of the rubber 2, the raised columns 3 are internally provided with tooth holes 4 in which the comb teeth 1 are arranged and cavities 31 for accommodating the comb teeth 1, the tooth holes 4 extend through a front side of the rubber 2, and the cavities 31 are sealed except for the tooth holes 4; hence, the comb teeth 1 are passed through the tooth holes 4 from the front side of the rubber 2 and into the cavities 31, so that the comb teeth 1 are fixed on the rubber 2; and
a hook 5 is arranged at one end of the comb tooth 1, and the tooth holes 4 are internally provided with clamping pieces 6 which can be fitted into the cavities 31 and fixed, for example, the length of the cavities 31 is greater than the diameter of the tooth holes 4, so that the hooks 5 are tightly fitted into the cavities 31 and hook the clamping pieces 6. The diameter of the tooth holes 4 is equal to or smaller than the inner diameter of the cavities 31. Since the rubber 2 is made of a flexible material and has a certain elasticity, the diameter of the tooth holes 4 of the above two specifications can allow the arrangement of the clamping pieces 6 in the cavities 31. Most preferably, the inner diameter of the cavities 31 matches the outer diameter of the comb teeth 1, so that inner walls of the cavities 31 can exert a force on the comb teeth 1 after the comb teeth 1 are bent and fitted into the cavities 31, thus imparting the comb teeth with a good fixing effect. Theoretically, a smaller inner diameter of the cavities 31 enables the comb teeth 1 to have a better fixing effect, but increases the difficulty of fitting the hooks 5 of the comb teeth 1 into the cavities 31, while larger cavities 31 can reduce the difficulty of fitting the hooks 5 of the comb teeth 1 into the cavities 31, but weaken the fixing effect of the comb teeth 1 in the cavities 31, so their relative specifications need to be moderately set. In addition, the hooks 5 can hook the clamping pieces 6 followed by being together inserted into the cavities 31, and the manner in which the comb teeth 1 and the rubber 2 are assembled is very easy to achieve.

[0049] The comb teeth 1 are softer than traditional plastic comb teeth to overcome the problem of hair tangling, and therefore can be made of nylon yarn or other similar flexible materials instead, e.g. nylon yarn with a diameter of 0.7-0.8 mm; the comb tooth (1) has one end bent to form the hook 5 and the other end formed as a spherical or similarly shaped comb tooth head; and the comb tooth head may be formed by hot working of nylon yarn, or by adhesion of other substances on the other end of nylon yarn. Compared with the comb teeth formed by injection molding and then engaged on a rubber in a traditional connection method, the nylon comb teeth are softer, which can overcome the problem of hair tangling easily caused by the traditional plastic injection comb teeth during use; and meanwhile, the invention also solves the resulting problem of fixing the comb teeth 1.

[0050] Preferably, the thickness of the rubber 2 in a cross-sectional direction gradually increases from the middle to the edge, i.e. the thickness of an intermediate portion of the rubber 2 is smaller than that of an outer edge portion thereof, which not only enables the intermediate portion that is first contacted and deformed to be the softest part so as to enhance user experience, but also can facilitate the restoration of the deformed rubber 2 by gradually increasing the elastic force. Practice shows that a rubber with a uniform thickness has a small probability of being unable to automatically restore in use, but the above design of gradual thickening from the middle to the edge can completely avoid this problem. Most preferably, the raised columns 3 and the rubber 2 are integrally formed by injection molding. In general, the thickness H1 of the center of the body portion of the rubber 2 (i.e. except for the outer edge for rubber fixing) is 1-3 mm, the thickness H2 of the outer edge is 2-5 mm, and the thickness is gradually increased from the center to the outer edge, but uniform thickening from the center to the edge is also not required; and of course, theoretically, stepwise thickening is also a feasible scheme (for example, the entire rubber is divided into three parts of 1.5 mm, 2 mm and 3 mm from the inside to the outside). In principle, the thickness of the rubber 2 can be specifically selected according to product parameters, materials and the like, but the overall requirement of relative thickness difference must be considered.

[0051] Preferably, the comb handle 7 comprises a placement groove 8 for placing the rubber 2, a transverse engaging slot 9 is arranged at an edge of the placement groove 8, an engaging block 10 is arranged at an outer edge of the rubber 2, the rubber 2 is mounted in the placement groove 8, and the engaging block 10 is in snap fit with the engaging slot 9 so that the center of the rubber is raised toward the front side.

[0052] Preferably, the placement groove 8 of the comb handle 7 of the comb of the invention is bent toward the back side of the rubber 2, so that the placement groove 8 is arranged along a curved surface.

[0053] The comb manufactured by the method has an ingenious structure and low overall manufacturing cost, can well solve the problem of hair tangling and is also easy to clean; and meanwhile, the comb also completely retains all the functions of a traditional air-cushion comb without any reduction, and with a special comb handle structure, the comb provides a smooth combing surface which has a greater contact area with hair or scalp when hair is combed, which is not available for a traditional air-cushion comb.
