DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 2 to 5, the present invention provides a zipper with a smooth pull function, comprising a zipper body 10, a puller 20 and a flexible element 30. Wherein the zipper body 10 includes a top plate 11, a bottom plate 12 disposed on the top plate 11, a connected portion 13 integrally disposed between the top plate 11 and the bottom plate 12, two slide grooves 14 formed between the top plate 11 and the bottom plate 12 and two sides of the connected portion 13 for receiving a zipper chain 41, two pivot seats 15 each having a pivot hole 16 disposed on a top surface of the top plate 11, two retaining elements 17 disposed near one side of the top plate 11 and a through hole 18 formed ear another side of the top plate 11.
Besides, the puller 20 has a rectangular shape, and including a pivot portion 21 formed at one side thereof and a contacted portion 22 projected from the pivot portion 21. Wherein the pivot portion 21 is pivoted in the two pivot holes 16 for pivoting the puller 20 on the top surface of the zipper body 10.
Moreover, the flexible element 30 is made of a flexible element, and having a fixed portion 31 formed at one side thereof and a hook portion 32 formed at another side thereof. The flexible element 30 is receiving between the two pivot seats 15 of the zipper body 10. Wherein the fixed portion 31 is retained by the two retaining elements 17, and the hook portion 32 is inserted into the through hole 18 of the zipper body 10 for retaining the hook portion 32 in the zipper chain 41.
Furthermore, the top plate 11 has a leveling portion 111 formed at one side thereof and two sides thereof, a bottom plate 12 having a smooth portion 121 formed at one side thereof and two sides thereof. The leveling portion 111 and the smooth portion 121 respectively has a guiding surface 112 and a guiding surface 122 with an inclined or curviform surface. The leveling portion 121 has a concave groove 113 with a V-shaped formed at a front and an inside thereof. The smooth portion 121 has a corner 123 with an arc shape.
Referring to FIG. 6, the zipper body 10 is assembled with the plastic-steel zipper chain 40 by the two slide grooves. Using the puller 20 can control the plastic-steel zipper chain 40 in an open state or a close state. When the puller 20 will be pulled along the zipper chain 41, the flexible element 30 is pulled by the contacted portion 22 of the puller 20 for separating the hook portion 32 from the zipper chain 41 of the plastic-steel zipper chain 40. So the puller 20 is slid on the zipper chain 41 smoothly for controlling the zipper chain 41 in the open state or the close state. When the puller 20 is released from the user, the hook portion 32 will be broken away from the puller 20. So the hook portion 32 is returned to an original position (the hook portion 32 is retained in the zipper chain 41), then the zipper is in the close state.
Furthermore, when the zipper body 10 is pulled by the puller 20 along the zipper chain 41, the concave groove 113 and the corner 123 will avoid to contact the zipper chain 41, and the leveling portion 111 and the smooth portion will contact the zipper chain 41 first for getting the smooth pull function.
Referring to FIGS. 7 to 8, a second embodiment of the present invention provides a zipper body 10 including a plate 11 having a leveling portion 111′ formed at one side thereof and two sides thereof, a bottom plate 12 having a smooth portion 121′ formed at one side thereof and two sides thereof. The leveling portion 111′ and the smooth portion 121′ respectively has a guiding surface 112′ and a guiding surface 122′ with an inclined or curviform surface. The leveling portion 121′ has a concave groove 113′ with a V-shaped formed at a front and an inside thereof. The smooth portion 121′ has a corner 123′ with an arc shape.
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 modification 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.
