Description
FIELD OF THE INVENTION
[0001] The present invention relates to a zipper with a smooth pull
function, especially to a zipper body being made of a metal or
plastic material used on a plastic-steel zipper chain for pulling
the zipper easily and smoothly.
BACKGROUND OF THE INVENTION
[0002] Referring to FIG. 1, a zipper of the prior art at least
includes a zipper body 10a and a puller 12a pivoted on the zipper
body 10a. So as to use the puller 12a to pull the zipper body 10a
along a zipper chain 20a for controlling the zipper chain 20a in an
open state or a close state.
[0003] Moreover, the zipper of the prior art further comprises a
flexible element 12a disposed on the zipper body 10a, and having a
hook portion 13a inserting in the zipper body for retaining the
puller 11a on the zipper body 10a.
[0004] However, the zipper of the prior art is used on the jeans.
The jeans will result a plurality of creases thereon, when the
jeans was washed. It will lead to a zipper chain of the jeans in a
non-level state. And the zipper chain 20a of the prior art is made
of a plastic-steel zipper chain, so that the user pulls the zipper
along the zipper chain 20a difficultly, and it will generate more
serious question due to above.
[0005] With the employment of unique considerations and application
of theories, and based on several years experience in specialized
production of all flexible assembly systems and mechanisms, so that
the inventor has come up with an innovative zipper with a smooth
puller function.
SUMMARY OF THE INVENTION
[0006] The primary object of the present invention is to provide a
zipper with a smooth pull function. The zipper has a level portion
for leveling a non-level zipper chain.
[0007] Another object of the present invention is to provide a
zipper with a smooth pull function. The zipper has a smooth portion
smoothly used on the zipper chain that is made of plastic-steel
zipper chain.
[0008] In order to achieve the above objects, the present invention
provides a zipper with a smooth pull function comprising a zipper
body and a puller. Wherein the zipper body includes a top plate
having a leveling portion formed at one side thereof, a bottom
plate having a smooth portion formed at one side thereof and two
slide grooves formed between the top plate and the bottom, and the
leveling portion defined a concave groove formed at an inside
thereof and the smooth portion defined a corner formed at outside
thereof. And the puller is connected with the top plate of the
zipper body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] 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.
[0019] 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.
[0020] 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.
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.
