Description

Double rail waterproof zipper

The invention relates to a zipper, in particular to a double-track waterproof zipper structure capable of preventing water from penetrating.

The conventional zipper usually comprises two zipper pieces of cloth, which are respectively combined with the sprocket on the inner side of the zipper piece, and a sliding element (zipper head) movably coupled between the sprocket of the two zipper pieces, when the sliding element moves , can drive the chain links of the two zipper pieces together or separate. However, the above-mentioned zipper is coupled by the fastener elements, and there are many gaps between the fastener elements, so that it does not have a waterproof effect. For this reason, there are some waterproof zipper designs, but the conventional waterproof zipper still has a chain-tooth structure, but through other waterproof technology to prevent water penetration, the special waterproof zipper has no sprocket, it is similar to the structure of the bag. , for example, as shown in US Pat. No. 7,536,758.

However, similar to the waterproof zipper shown in the US Pat. No. 7,536,758, the two-piece plastic integrally formed zipper sheets have different shapes, so it is necessary to develop two sets of molds to separately manufacture two zipper sheets, resulting in high manufacturing cost. Moreover, the degree of tightness of the chain link structure for interlocking with each other and the stability of the chain are insufficient, and leakage may still occur, and in particular, it is impossible to resist the pulling force, and the two zipper sheets are peeled off. In addition, the two zipper pieces of the special sliding element (zipper head) cannot be chained to form a large gap or an unjoined gap. The waterproof function is greatly reduced.

The object of the present invention is to provide a double-track waterproof zipper, which is improved by the structure of the chain link portion of the double-track waterproof zipper, thereby preventing the zipper from being peeled off and being reliably waterproof and infiltrating.

In order to achieve the above object, a preferred embodiment of the dual-track waterproof zipper of the present invention comprises: a first zipper piece and a second zipper piece of the same shape, and a slidingly coupled to the first zipper piece and the second zipper a sliding element between the sheets, wherein: the first zipper piece and the second zipper piece respectively comprise a piece body, a buckle integrally formed on one side of the piece body, and a buckle portion formed on one side of the buckle piece; The clasp portion includes a buckle portion, a protruding portion disposed on one side of the buckle portion, a first tight portion connected between the buckle portion and the protruding portion, and a protruding portion a second sealing portion on the other side of the protruding portion; the buckle portion includes a recess for recessing one side of the buckle, and two hooks formed on two sides of the groove; the protruding portion has a neck The rib of the constriction. The rib of the protruding portion of the first zipper piece can be embedded in the groove of the buckle portion of the second zipper piece, so that the two hooks of the second zipper piece are fastened to the ridge of the first zipper piece The neck portion and the first contact portion and the second contact portion of the first zipper sheet are in close contact with the surface of the two hooks of the second zipper sheet. The rib of the protruding portion of the second zipper piece can be embedded in the groove of the buckle portion of the first zipper piece, so that the two hooks of the first zipper piece are fastened to the ridge of the second zipper piece The neck portion and the first contact portion and the second contact portion of the second zipper piece are in close contact with the surface of the two hooks of the first zipper piece.

Double-track waterproof zipper according to the above preferred embodiment The second contact portion has a length sufficient to abut the end portion of the first zipper piece and the second zipper piece and cover one of the hooks.

The double-track waterproof zipper according to the above preferred embodiment, wherein the first zipper piece and the second zipper piece are provided with a waterproof sleeve at one end thereof, the waterproof sleeve having a pair of openings for sliding elements, the sliding element The opening is inserted into the waterproof cover.

The double-track waterproof zipper according to the above preferred embodiment, wherein the first zipper piece and one end of the second zipper piece have a first nip portion that is heat-pressure fused together; the first zipper piece and the first zipper piece The other end of the two zipper sheets has a second nip which is heat-fused together.

The double-track waterproof zipper according to the above preferred embodiment, wherein the first zipper piece and the second zipper piece are respectively integrally formed of plastic.

Therefore, the double-track waterproof zipper of the present invention can be installed and applied on articles requiring waterproofing, and the chain structure of the first zipper piece and the second zipper piece is improved, and the first zipper piece and the second zipper piece chain are improved. The tightness and stability of the joint prevent the first zipper sheet from peeling off from the second zipper sheet and prevent water from penetrating. In addition, the invention can make the sliding component into the waterproof sleeve through the design of the waterproof sleeve, and hide the gap caused by the sliding component part in the waterproof sleeve to achieve the effect of waterproofing.

The structural features and other functions and objects of the present invention will be described in detail below with reference to the accompanying drawings. Referring to the first and second figures, a preferred embodiment of the dual-track waterproof zipper of the present invention includes a first shape of the same shape. a zipper piece 1 and a second zipper piece 2, and a sliding member 3 slidably coupled between the first zipper piece 1 and the second zipper piece 2, drive the first zipper piece 1 and a second through the sliding element 3 The zipper sheet 2 is chained or separated, wherein: as shown in the third figure, the first zipper sheet 1 and the second zipper sheet 2 are respectively formed by plastic molding, and the preferred structures respectively include a body 11 . 21, the buckles 12, 22 integrally formed on one side of the sheets 11, 21, and the fastener portions 13, 23 formed on one side of the buckles 12, 22. The sheets 11, 21 are long plastic sheets for bonding to other articles, such as rain. Clothes, suitcases, etc. The fasteners 13 and 23 are configured to be coupled to each other. The preferred structure includes a buckle portion 131, 231, and a buckle portion 132, 232 disposed on one side of the buckle portion 131, 231. The first adhesive portions 133 and 233 connected between the buckle groove portions 131 and 231 and the convex buckle portions 132 and 232 and the second adhesive portions 134 and 234 protruding from the other side of the convex buckle portions 132 and 232 . The buckle portions 131 and 231 include recesses 1311 and 2311 recessed on one side of the buckles 12 and 22, and two hooks 1312 and 2312 formed on opposite sides of the recesses 1311 and 2311, so that the grooves 1311 and 2311 are formed into a circle. The arc groove surface, and the ends of the hooks 1312, 2312 are formed as a circular arc top surface. The protruding portions 132 and 232 have ribs 1322 and 2322 of a neck portion 1321 and 2321, and the ribs 1322 and 2322 have the same sectional shape as the grooves 1311 and 2311. The first adhesive portions 133, 233 are used to abut against one of the hooks 1312, 2312 to achieve the sealing function. The length of the second contact portions 134, 234 is sufficient for the ends thereof to abut each other to the sheets 11 and 21 of the first zipper sheet 1 and the second zipper sheet 2, and the second nip portions 134, 234 are wrapped. Covering another of the clasps 1312, 2312.

Accordingly, the fifth and sixth figures show that the first zipper piece 1 and the second zipper piece 2 can be coupled or separated by the sliding movement of the sliding member 3 (the zipper head). The state of the chain is as shown in the fourth figure, so that the ribs 1322 of the protruding portion 132 of the first zipper piece 1 can be embedded in the grooves 2311 of the buckle portion 231 of the second zipper piece 2, so that the second zipper piece 2 The two fastening hooks 2312 are fastened to the necked portion 1321 of the protruding strip 1322 of the first zipper piece 1, and the first adhesive portion 133 and the second adhesive portion 134 of the first zipper sheet 1 are closely attached to the first fastening portion 134.
