Description

    FIELD OF THE INVENTION
  • The present invention relates to a slide structure for zipper, which has light weight, less material use while keeping sufficient strength. [0001]
    • BACKGROUND OF THE INVENTION
  • FIG. 1 shows a prior art slide structure for a zipper, the slide structure comprises a [0002] slide body 10 a and a pulling tab 11 a pivotally arranged on the slide body 10 a. By operating the tab 11 a to move the slide body 10 a, the zipper can be opened or closed.
  • Moreover, an [0003] elastic plate 12 a is arranged on the slide body 10 a and has a locking part 13 a. The locking part 13 a can penetrate, from topside of the slide body 10 a, into the inner part of the slide body 10 a, thus clamping the position of the slide body 10 a on the zipper. When the tab 11 a is not pulled, the position of the slide body 10 a is clamped. Therefore, the slide with such structure has self-locking function.
  • However, the slide with above-mentioned structure is generally made of zinc alloy by die-casting. To ensure sufficient structural strength, the [0004] slide body 10 a should have enough thickness. Therefore, the slide body 10 a is not sufficiently compact and light-weight to meet practical requirement.
    • SUMMARY OF THE INVENTION
  • It is an object of the invention to provide a slide structure for zipper, which has light weight, less material use while keeping sufficient strength. [0005]
  • To achieve above object, the slide structure for zipper according to the present invention has a slide body and a tab. The slide body has two sliding groove and has rounded concave groove on at least one surface thereof. The tab has a pivotal end on one side thereof and pivotally connected to top of the slide body.[0006]
  • The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which: [0007]

  • FIG. 9 is a sectional view along line B-B of FIG. 7.[0016]
    • DETAILED DESCRIPTION OF THE INVENTION
  • With reference now to FIGS. 2 and 3, the present invention is intended to provide a self-locking slide structure for zipper. The self-locking slide structure according to the present invention comprises a [0017] slide body 10, a pulling tab 20 and an elastic plate 30. The slide body 10 comprises a top plate 11 and a bottom plate 12 with a predetermined separation therebetween. The top plate 11 and the bottom plate 12 is connected by a connection part 13 and two sliding grooves 14 are formed between the top plate 11 and the bottom plate 12 and on both sides of the connection part 13 to receive the zipper (not shown). The top plate 11 of the slide body 10 has two pivotal stages 15 arranged along the lengthwise direction. The pivotal stage 15 each has a concave-shape pivotal groove 16 at the center part thereof and the pivotal stage 15 has a U-shaped clamping cover 18 on the topside thereof. The top plate 11 of the slide body 10 has a through hole 17 between the two pivotal stages 15.
  • The [0018] tab 20 is of long-plate shape and has a pivotal end 21 on one end thereof. The pivotal end 21 is pivotally arranged within the concave-shape pivotal groove 16 of the slide body 10 such that the tab 20 is pivotally engaged on top of the slide body 10. The U-shaped clamping cover 18 is used to prevent the pivotal end 21 from escaping from the concave-shape pivotal groove 16 of the slide body 10, thus clamping the tab 20.
  • The [0019] elastic plate 30 is made of materials with good elasticity and has a bent part 31 to enhance the flexibility of the elastic plate 30. The bent part 31 has a locking part 32 on one end thereof. The elastic plate 30 is placed between the two pivotal stages 15 of the slide body 10 and is retained by the U-shaped clamping cover 18, thus preventing the elastic plate 30 from escaping from the two pivotal stages 15 of the slide body 10. Moreover, part of the elastic plate 30 is placed atop the pivotal end 21 of the tab 20. The locking part 32 of the elastic plate 30 passes through the through hole 17 of the slide body 10 and penetrates into a position between the sliding grooves 14 to lock on the zipper.
  • The present invention is characterized that the [0020] slide body 10 has rounded concave groove 19 on at least one surface (with reference to FIGS. 4 to 6). In a preferred embodiment of the present invention, the slide body 10 has a rounded concave groove 19 on topside thereof. In other word, the slide body 10 has a rounded concave groove 19 on top plate 11 thereof. The rounded concave groove 19 is directly formed on the top plate 11 when the slide body 10 is shaped by die-casting zinc alloy.
  • The [0021] slide body 10 is assembled on the zipper (not shown) through the two sliding grooves 14 and the tab 20 is operated to control the open and close of the zipper. When the tab 20 is pulled, the pivotal end 21 pushes upward the elastic plate 30 and the locking part 32 is moved upward to escape from the zipper. As a result, the tab 20 smoothly drags the slide body 10 on the zipper to control the close and open of the zipper. When the tab 20 is released, the pivotal end 21 no longer pushes upward the elastic plate 30 and the locking part 32 of the elastic plate 30 is locked again to the zipper. Therefore, the slide body 10 is in a locked state.
  • With reference now to FIGS. [0022] 7 to 9, in this preferred embodiment, the slide body 10 has a rounded concave groove 19 and a rounded concave groove 19′ on the topside and bottom side thereof, respectively. In other word, the slide body 10 has a rounded concave groove 19 on top plate 11 thereof and a rounded concave groove 19′ on the bottom plate 12 thereof. Alternatively, the slide body 10 also can only have a rounded concave groove 19 on the bottom plate 12 thereof.
  • The present invention is characterized in that the [0023] slide body 10 is provided with rounded concave groove 19 (19′). The provision of the rounded concave groove reduces the weight of the slide body 10 while the structural strength of the slide body 10 is not influenced. The materials used and the cost of the slide body are reduced. Moreover, the cost of slide depends the processing and plating thereof. When the weight of the slide is reduced, the cost thereof is reduced.
  • Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims. [0024]
