Definitions

  • the invention belongs to the technical field of daily necessities, and in particular relates to a rubber assembly useful for a comb, a comb comprising the rubber assembly, and a method for manufacturing a comb.
  • a comb is a tool for combing hair, and its types and materials are various.
  • a comb is a common item in people's daily life, which is a very necessary and practical tool for hair care, especially for long hair.
  • air-cushion combs For an air-cushion comb (also referred to as an airbag comb), comb teeth of the comb are placed on a rubber or other similar flexible materials, a cavity is also formed between the rubber and a comb body, the comb teeth exert a force on the cavity when acting on hair or scalp during use, and since the rubber is soft, air in the cavity is discharged from a special air hole. Accordingly, the comb can better fit the shape of the scalp, and the flexible contact effect can also achieve the massage for the scalp.
  • KR101317714B1 discloses a comb provided with detachable comb teeth to reduce manufacturing cost and accommodation space.
  • the comb comprises a body portion 110 formed with a handle 111 and having a body 112 into which a comb tooth body is inserted, wherein the comb tooth body is detachably assembled together with the body to form comb teeth thereon as well as an opening and closing portion 130 on an end portion of the body.
  • Guide grooves 113 formed on both ends of the body are connected to guide protrusions 122 formed on both ends of the comb tooth body.
  • a hairstyle generated by a comb body can be selected according to a user's hair condition, hair amount and hair length, and a comb tooth body suitable for the hairstyle is selected.
  • KR20160080197A discloses comb teeth for a hair brush, which include: a scalp scratch preventing member formed at the top of an upright comb tooth stand; an upper bracket and a lower bracket formed at the bottom of the upright comb tooth stand; and a plurality of rings formed on a middle part of the upright comb tooth stand.
  • An upper locking claw 130, a lower locking claw 140 and a locking lever 150 located therebetween are arranged at the bottom of the comb teeth; a rubber plate 200 is provided with comb tooth holes 210 so that their lower ends can be fixed and combined with the rubber plate 200 to form the lower locking claw 140; and the upper locking claw 130 is formed in a conical shape so that the comb teeth are fixed on the rubber plate 200.
  • KR20110085799A also discloses a comb, and provides a comb capable of preventing dust from being adsorbed on a comb plate and comb teeth and easily removing tangled hair.
  • the comb comprises: a body 1; a first comb plate 11 adhered to the body; a second comb plate 12 adhered to the first comb plate; a bottom plate 3 adhered to the first and second comb plates; and comb teeth 6 which are inserted to move up and down between the first comb plate and the second comb plate.
  • the first comb plate comprises a top plane and a side plane surrounding the top plane, a plurality of holes are formed in the top plane, and the side plane is formed in a zigzag.
  • the bottom of the comb teeth 6 is also fitted into holes 2 through recesses 5c so that the comb teeth 6 are fixed on the second comb plate 12, which is similar to KR20160080197A .
  • KR20160047289A discloses a hair brush with triple comb teeth, which is capable of, when tangled hair is combed, preventing the hair from being pulled or cut, by forming the comb teeth to have three lengths; and capable of, when hair is combed, preventing the hair from being cut due to the insertion of the hair between the comb teeth and a comb tooth pad.
  • the hair brush 10 is formed by ,coupling a comb tooth pad 40 into which a plurality of comb teeth 30 are inserted and fixed in a predetermined arrangement, with one surface of a body portion 20, and coupling a handle 50 with the other part of the body portion 20, wherein the comb teeth 30 have a triple structure including long comb teeth 31, middle comb teeth 32 and short comb teeth 33 which have different lengths, and wherein protrusions 41 for preventing the insertion of hair protrude among the comb teeth 30 on an upper surface of the comb tooth pad 40.
  • the comb tooth pad 40 can be formed from a rubber of an air-cushion comb, two convex rings 30a and 30b are arranged at the bottom of the comb teeth 30, and the comb teeth 30 are engaged into comb tooth holes of the comb tooth pad 40 via the two convex rings 30a, 30b to achieve the fixing of the comb teeth.
  • CN2347471Y discloses a combined comb comprising a head and a handle, wherein the head has a tail handle, the handle is hollow, and the two parts are mutually inserted and fixed and then connected as a whole.
  • combs of different types or production series can be assembled by different combinations, it can be seen from FIG. 1 that comb teeth are fixed on a rubber in a manner that the outer diameter of the bottom of the comb teeth is greater than the inner diameter of comb tooth holes.
  • comb teeth are mostly formed by injection molding of materials such as plastic, and upper and lower locking claws capable of being engaged on comb tooth holes of a rubber are arranged at the bottom of the comb teeth, which are also common fixing structures for the comb teeth.
  • KR20160080197A also discloses comb teeth provided with several rings 160 adapted for combing wavy hair, the structure does not fundamentally solve the problem of hair tangling caused by plastic comb teeth used in the type of the comb 2.
  • the root cause of this problem is that the material of comb teeth is relatively hard, and when curled hair is tangled, the tangled part will be pushed to move downward, and eventually the comb teeth will be firmly stuck by the tangled hair, which will affect the implementation of combing.
  • gluing may be selected, i.e. the comb teeth are applied with glue at the bottom and then placed in comb tooth holes.
  • a sufficient contact area is needed, so the thickness of the rubber is increased to provide a sufficient contact area therebetween to facilitate fit and fixing.
  • the increase in the thickness of the rubber will obviously weaken the overall use effect of an air-cushion comb, and an external force required for the deformation of its rubber is increased, which will greatly affect the massage effect and the user's satisfaction with the air-cushion comb.
  • An object of the invention is to solve the above problems and to provide a new fixing structure for comb teeth of an air-cushion comb, thereby differently solving the problem of tangling in an existing air-cushion comb while ensuring the firm combination of comb teeth and a rubber.
  • a rubber assembly which comprises comb teeth and a rubber, wherein several raised columns are arranged at a back side of the rubber, and the bottom of the comb teeth is bent and then fitted into the raised columns by clamping pieces so that the fixing effect of the raised columns with the rubber meets the requirements, and the thickness of the body of the rubber is also not increased so that the overall use effect of the air-cushion comb is not affected; and the raised columns enable relevant fixing structures (i.e. bending of the comb teeth and the clamping pieces) of the comb teeth and the rubber to have sufficient arrangement space, i.e. the combination of the raised columns with the fixing manners of bending and the clamping pieces can also ensure that the fixing strength meets the requirements without affecting the thickness of the rubber.
  • relevant fixing structures i.e. bending of the comb teeth and the clamping pieces
  • a comb comprising the rubber assembly
  • it is mainly intended to use the rubber assembly on the comb to achieve a non-tangling comb.
  • the rubber assembly and a comb handle are connected by an engaging structure and therefore detachable, which is very beneficial in the maintenance of the comb.
  • the rubber assembly is detachable and hence can be disassembled to form a smooth component, and then the rubber assembly is placed in water with the comb teeth downward, and can be lifted and lowered to allow curled hair to automatically fall off, thus it can be very convenient to clean most of the hair.
  • a method for manufacturing a comb wherein 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.
  • the comb also solves the problems with the fixing strength and the safety caused by fixing with glue in a traditional non-tangling comb, and problems such as a weakened massage effect caused by the increase in the thickness of the rubber.
  • softer comb teeth are selected to solve the problem of hair tangling in a traditional air-cushion comb; and meanwhile, the fixing structure of the comb teeth is redesigned, so that the thickness of the rubber is not increased which would otherwise adversely affect the overall massage effect of the air-cushion comb, and it is also possible to ensure that the comb teeth are firmly and effectively fixed to the rubber, thereby avoiding the problems in use caused by insufficient fixing strength of the comb teeth.
  • the rubber assembly is detachable and easy to clean on the one hand, and on the other hand, the body of the combing surface is straight due to the design of the comb handle structure, so that the combing surface has a greater contact area with a user's hair or head.
  • 1 comb tooth; 2: rubber; 3: raised column; 4: tooth hole; 5: hook; 6: clamping piece; 7: comb handle; 8: placement groove; 9: engaging slot; 10: engaging block; 11: first inclined surface; 12: second inclined surface; 13: notch; 31: cavity; 81: flat end of placement groove; 82: low point of placement groove.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the thickness H1 of the center of the body portion of the rubber 2 i.e.
  • 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).
  • 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).
  • the raised columns 3 and the rubber 2 are integrally formed by injection molding.
  • 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.
  • 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.
  • a comb comprises a comb handle 7 and a comb portion fitted thereon, wherein the comb portion is the above rubber assembly.
  • 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.
  • 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.
  • 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).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a method for manufacturing a comb comprises the following steps:
  • 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.
  • 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.
  • 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.
