ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a zipper's pull hook structure having a replaceable pull sheet and, more particularly, to a zipper's pull hook structure capable of connecting a pull sheet and a zipper head body so that the pull sheet can be replaced flexibly.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a prior art zipper head structure comprises a zipper head body
10
and a pull sheet
11
. The pull sheet
11
is connected with the zipper head body
10
by using a pull hook
12
so that the pull sheet
11
can be used to pull the zipper head for opening or closing a zipper.
The pull hook
12
has a ring portion
13
and a hook portion
14
. The ring portion
13
is connected with a pivotal seat
15
at the top of the zipper head body
10
. The hook portion
14
is hooked with a joint ring
16
of the pull sheet
11
so that the pull hook
12
can be connected between the zipper head body
10
and the pull sheet
11
.
The above pull hook
12
is hooked at the joint ring
16
of the pull sheet
11
via the hook portion
14
. The hook portion
14
is originally of panel shape. When the hook portion
14
is to be hooked at the joint ring
16
of the pull sheet
11
, it is necessary to penetrate the hook portion
14
into the joint ring
16
of the pull sheet
11
and then bend the hook portion
14
into a fixed ring shape so that the ring-shaped hook portion
14
can be joined with the joint ring
16
of the pull sheet
11
. After the hook portion
14
is bent into a ring shape, it will form fixed connection with the joint ring
16
. It is unable to separate them so that the pull sheet
11
cannot be replaced. If the pull sheet
11
is damaged, the whole zipper head needs to be replaced.
Moreover, because the pull sheet
11
cannot be replaced, a user must use the same pull sheet
11
for a long time, lacking novelty and variability. This kind of design of the pull sheet
11
thus cannot meet the requirement of today's fashionable people.
Accordingly, the above zipper head has inconvenience and drawbacks in practical use. The present invention aims to resolve the problems in the prior art.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a zipper's pull hook structure having a replaceable pull sheet, wherein a hook portion of the pull hook has an opening. The opening is provided with resilient closing function by a resilient sheet portion. In order to open the opening, it is only necessary to push a free end of the resilient sheet portion to swing inwards. The hook portion can thus be connected with a joint ring in mobile way, and can be separated from the joint ring so that the pull sheet can be easily replaced.
Another object of the present invention is to provide a zipper's pull hook structure having a replaceable pull sheet, whereby when the joined pull sheet is damaged, the pull sheet can be separately replaced. It is not necessary to replace the whole zipper head, hence avoiding needless waste.
Yet another object of the present invention is to provide a zipper's pull hook structure having a replaceable pull sheet, wherein the pull sheet can be replaced in mobile way. A user needs not to use the same pull sheet for a long time, and can replace a pull sheet of different shape at any time, hence having better novelty and variability and conforming to the requirement of today's fashionable people.
To achieve the above objects, the present invention provides a zipper's pull hook structure having a replaceable pull sheet. The pull hook comprises a first ring portion, a second ring portion, a hook portion, and a resilient sheet portion, which are integrally formed. The first ring portion and the second ring portion are stacked together. The hook portion is bent into a hook shape, and has an opening. The pull hook can be hooked at the pull sheet via the hook portion. The resilient sheet portion is at the opening of the hook portion. One end of the resilient sheet portion forms a free end. The opening is closed flexibly by the resilient sheet portion. A zipper's pull hook structure having a replaceable pull sheet is thus formed.
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:
