Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The scheme relates to a novel zipper tooth, which is fixedly arranged on a cloth rib 11 of a cloth belt 1 in application as shown in figures 1-10. In order to facilitate the explanation of the structure of the fastener element, the reference direction of the fastener element is firstly set, and the reference state of the fastener element fixed on the cloth belt 1 is taken as a reference, and the reference direction comprises a width direction corresponding to the extending direction of the cloth ribs 11, a length direction in the plane of the cloth belt 1 and perpendicular to the extending direction of the cloth ribs 11, and a thickness direction perpendicular to the plane of the cloth belt 1.

The fastener element includes a fixing portion 2 and a coupling portion 3 provided along the longitudinal direction. The fixing part 2 and the cloth rib 11 are fixedly installed with each other, and the cloth rib groove 20 is arranged on the fixing part 2 for riveting and fixing the cloth rib 11. As shown in fig. 1, the fixing portion 2 has two clamping portions, the tendon distribution groove 20 is formed between the two clamping portions, and the two clamping portions are in an open state before being riveted; after being riveted on the cloth rib 11, the two clamping parts are clamped and riveted.

The combining part 3 extends out of the cloth rib 11. The joint 3 includes a body 31 and two arms 32. The tooth body 31 is a main body part of the combining part 3, the tooth body 31 is connected (integrated) with the fixing part 2, the structural shape of the tooth body 31 is not particularly limited, and a specific embodiment is given, the tooth body 31 is a cuboid-like body plate structure and has a free end part 312, two corresponding side surfaces along the width direction and two corresponding side surfaces along the thickness direction. In the closed state of the zipper, the free end 312 faces the direction of the cloth rib of the opposite side cloth tape, and the free end 312 preferably extends to be disposed to be in contact with the cloth rib of the opposite side cloth tape, so that the end surface of the free end 312 of the tooth body 31 is preferably designed to be an arc surface 3121 with smooth surface transition, which is favorable for the contact fit. The design of the arc-shaped surface 3121 can also smooth the surface shape of the chain teeth, and improve the touch feeling of the chain teeth, and in addition, the free end 312 with the arc-shaped surface can be seen as a human-shaped head shape from the side, and the new personality is provided.

The two arms 32 are respectively protruded from two corresponding side surfaces of the tooth body 31 in the thickness direction, and the arms 32 extend from the corresponding side surfaces of the tooth body 31 in the width direction to form an occlusion part. The two arms 32 extend toward the same side in the width direction, that is, the two arms 32 are disposed opposite to each other, rather than being disposed in a staggered manner. Occlusion positions are formed on two corresponding side surfaces in the thickness direction of the tooth body 31 and beside the corresponding tooth arms 32. Specifically, since the arms 32 are protruded from the side surfaces of the body 31, the side surfaces and the arms form a corresponding surrounding area therebetween, thereby forming an occlusion position. The occlusion position of the zipper teeth is used for the corresponding occlusion of the occlusion parts on the opposite sides, and the occlusion position which is compared in the same way is also used for the corresponding occlusion of the occlusion parts of the zipper teeth, so that the two-way occlusion interlocking is carried out in a way that the outer two arms are mutually inserted and locked, and the pulling and closing purposes are achieved.

The structural design of the tooth arm 32, preferably, can be designed to extend in an arc shape toward the width direction to form an arc arm, for example, an arc hook arm, and the end part forms an arc hook part, which correspondingly forms the occlusion part. The device can also be designed to be extended in a bending way to form a bent arm, the bending is carried out at least once, and the occlusion part is formed corresponding to all or part of the bending part. The tooth arms 32 can additionally be designed as straight arms. The scheme provides a specific embodiment, and a bent arm bent once is adopted.

Preferably, the two arms 32 can be symmetrically arranged in the same shape to form a double-sided symmetrical arm set (specific embodiments are given in this case); of course, different shapes can be asymmetrically arranged to form an asymmetric arm set.

As a specific preferred embodiment of the arm 32, the arm 32 is bent to form a bent arm, and the bent arm has a first arm 321 and a second arm 322. The first arm 321 is connected to the tooth shaft 32, more specifically, the first arm 321 is connected to the respective side of the tooth shaft 32 by its free end, and the length of the first arm 321 extends beyond the tooth shaft. The second arm 322 correspondingly constitutes the engaging portion. The extending direction of the first arm 321 and the second arm 322 is not particularly limited, and the angle formed between the first arm 321 and the second arm 322 is not particularly limited. In a preferred embodiment, the first arm 321 extends along the length direction and the second arm 322 extends along the width direction to form an L-shaped arm structure, although the first arm 321 may also be designed to be inclined at a certain angle with respect to the length direction, similarly, the second arm 322 may also be designed to be inclined at a certain angle with respect to the width direction, and the included angle between the first arm 321 and the second arm 322 may also be an acute angle or an obtuse angle.

Further, in order to facilitate the occlusion position, the position of the first arm 321 on the corresponding side surface in the thickness direction of the tooth body 31 is set to be close to the position corresponding to the free end of the tooth body 31, and the occlusion position 311 is formed correspondingly close to the non-free end. Specifically, the tooth body 31 is divided into a free end part 312 and a body part on both sides of the tooth arm 32 relative to the tooth arm 32, and the spatial position formed by the corresponding side surface of the body part and the arm surface of the first arm 321 is the occlusion position 311, so that the occlusion part (the second arm 322) can be placed and locked.

Further, the second arm 322 may be bent in any direction selected from two directions in the longitudinal direction. The preferred embodiment adopted herein is that the free end of the second arm 322 extends towards the side of the free end 311 of the tooth body 31, so that when meshing, the corresponding first arms 321 of the double-sided fastener elements can abut against each other and cooperate, and the second arm 322 can be relatively lengthened, which is beneficial to improving the meshing strength and the stability of the meshing structure. In an exemplary embodiment, the free end of the second arm 322 extends to be at least flush with the free end of the body 31. Given the preferred embodiment, the free end of the second arm 322 extends beyond the free end 311, so as to improve the locking strength between the teeth without affecting the opening and closing of the teeth.

The side surface of the tooth body 31 where the corresponding two tooth arms 32 extend outwards is the side surface facing the opposite side chain tooth to be locked, the whole space formed by the corresponding two tooth arms 32 on the side is a locking space, and a locking groove 33 is formed between the two tooth arms 32. Preferably, the clasping groove 33 is designed as a trapezoidal clasping groove with a wide mouth and a narrow bottom, that is, the two tooth arms 32 are slightly inclined outwards, so that the included angle between the two tooth arms and the tooth body 31 is slightly larger than 90 degrees. The design is beneficial to mutual simple and effective mutual inserting and locking of the double-side zipper teeth.

The zipper teeth are designed to be independently engaged on one side, and the zipper teeth on two sides of two cloth belts are engaged in pairs on one side to form a plurality of pairs of arranged engaging teeth. The meshing mode adopts a special mode of mutually inserting and locking two outer arms, and is different from the traditional mode in that the traditional meshing mode is that the side (corresponding side in the width direction) where the two-side zipper teeth are arranged face to face is designed with three-dimensional meshing limit, and the scheme adopts the mode that the two arms protrude in the thickness direction to be mutually inserted and locked in a double-outer mode (preferably, the two arms are mutually locked in a back-to-back mode). In other words, the side where the corresponding double-side zipper teeth are located face to face is limited in the corresponding width direction in an overlapping mode, and the tooth body of each side correspondingly enters the locking space of the opposite side; the occlusion limiting in the length direction and the thickness direction is realized by two tooth arms 32 which are skillfully and outwardly extended, the two tooth arms 32 at two sides are mutually combined in an embracing way, and the respective formed embracing locking grooves 33 tightly embrace and lock the tooth body parts at the opposite sides, which is explained by the specific embodiment, wherein the first arms 321 are oppositely and adjacently inserted and overlapped, and the second arms 322 are correspondingly matched with the occlusion positions 311 extending into the opposite sides for surface-to-surface locking of the long arms, so that the interlocking is realized in the length direction and the thickness direction, and the occlusion purpose is achieved.

According to the preferable scheme, the structural design of the zipper teeth can be suitable for various materials, the preferable embodiment is made of metal materials, and therefore the zipper teeth are high in holding strength, good in holding matching effect and quite textured.

Preferably, the fixing portion 2 has two clamping portions, and the specific shape structure of the two clamping portions can be any form, which gives a preferred embodiment and comprises a first fixing section 21 and a second fixing section 22 which are connected in a bending manner.

Thus, the present fastener element structure is novel and unique in design, and preferably can be designed to form a human-shaped dynamic fastener element structure, wherein the fastener element 31 corresponds to the upper half of the human shape, the free end 312 of the fastener element 31 is a human-shaped head, the two fastener arms 32 are two human-shaped arms, and the first fixing section 21 and the second fixing section 22 of the fixing portion 2 are a human-shaped thigh portion and a human-shaped shank portion, respectively, as shown in fig. 5, the fastener element is a double-arm raised small figure riding on the cloth rib 11, which is very novel, interesting and lovely. The specific posture of the small figure has flexible variability, and the figure effects of different dynamic styles can be obtained by changing the posture of the four limbs. In the specific embodiment, the human-shaped dynamic structure with different postures is formed by changing different bending angles of the first fixing section 21 and the second fixing section 22. Two types of chain tooth human-shaped models and three types of combination schemes are provided as shown in figures 8-10, and the design is strong and flexible. Of course, the scheme can be designed into a single-sided human shape or a double-sided human shape.

Based on the same idea, the invention also provides a novel chain belt, which comprises a cloth belt 1 and chain teeth, wherein the chain teeth are fixedly arranged on the cloth ribs 11 of the cloth belt 1, and the chain teeth are the novel chain teeth. The novel chain element structure is not described in a repeated way, and the beneficial effects are similar to those of the novel chain element structure.

Based on the same invention idea, the invention also provides a novel zipper, which comprises two zipper belts and a pull head, wherein the zipper belts are the novel zipper belts. The novel zipper can be applied to various products with zippers, such as clothes, bags, shoes, tents and the like.
