Abstract
A zipper slider comprises a pull head, and a pull part. The pull slider provides a zipper base joining a proboscis, and the proboscis at both ends thereof is arranged an axial engaging hole respectively. The pull part provides a pull string passing through the axial engaging holes with an end thereof joining a stopper and the other end thereof joining a puller.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a zipper slider, and particularly to an improvement of zipper slider, which can generate a rectilinear force to perform a better effect of zipper operation.




2. Description of Related Art




The zipper slider has been used as a fastener for joining and separating two parts of an article for years. Due to being easily operated, the zipper slider has replaced other fastening device to a certain extent and, for instance, the zipper has been used as a fastener for almost all wallets and readily made clothes.




The principle of the function of a zipper is that the zipper provides two opposite interlocking tooth tabs and a pulled zipper slider to fasten and unfasten two adjoining edges of an article by way of pulling the zipper slider along the two interlocking tooth tabs. The zipper slider is an essential part to carry out the movement of fastening and unfastening in spite of the interlocking tooth tabs being made of metal, nylon, or fiber reinforced plastics.




The conventional zipper slider, as shown in

FIG. 1

, has a pull head A and a puller B movably engaging with the pull head A. The puller B has a function of marking out or decorating except being pulled. Therefore, the puller B usually connects with the proboscis (nose part) C of pull head A in a way of an end of the puller B enclosing or surrounding the proboscis C.




The arrangement of combining the pull head A, puller B, and the proboscis C has been used for years without any change. Somehow, a minor change may be made is the configuration of the puller B only, but the device of the puller enclosing or surrounding is kept unchanged.




Under the circumstance of today's highly developed technology, new is a common aim for all industries to pursue incessantly. The slider of a zipper, which is kept immutable, is worth us to self-criticize and make an improvement genuinely.




SUMMARY OF THE INVENTION




An object of the present invention is to provide a zipper slider, in which the puller engages with a connection string instead of attaching to the probe directly to improve the effectiveness of the force exerted to pull the zipper slider.











BRIEF DESCRIPTION OF THE DRAWINGS




The present invention can be more fully understood by referring to the following description and accompanying drawings, in which:





FIG. 1

is a perspective view of a conventional zipper slider;





FIG. 2

is an exploded perspective view of a zipper slider according to the present invention; and





FIG. 3

is a perspective view illustrating the zipper slider shown in

FIG. 2

after assemble;





FIG. 4

is a perspective view of another zipper slider according to the present invention providing two pull pieces; and





FIG. 5

is a perspective view of a further zipper slider according to the present invention providing a nose without piercing hole.











DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 2

, a zipper slider of present invention comprises a pulled head


1


and a pull part


2


.




Wherein, the pulled head


1


at the lower part thereof part thereof is a zipper base


11


and at the upper surface thereof is associated with a proboscis


12


with a hollow part


13


between the proboscis


12


and the upper surface of zipper base


11


. But, the pulled head


1


has the same structure as the conventional zipper does so that no detail will be described further.




The proboscis


12


at both ends thereof provides an axial pierced hole


121


respectively extending inward from outside respectively to be passed through by a pull string


21


. The arrangement of probe


2


in the present invention is different from the conventional one.




The pulled part


2


is provided for being pulled by the user and is composed of the pull string


21


and a stopper


22


at an end of the pull string


21


and a puller


23


at another end of the pull string


21


. As shown in

FIG. 2

, the pull string


21


at both ends thereof fixes with the stopper


22


and the puller


23


respectively after being assembled. Hence, the stopper


22


and the puller


23


have a size greater than the axial pierced holes


121


respectively. The pulled piece


23


may be a plate, a doll or an article with other figures or significant characters or decorative patterns. The pull string


21


has a length greater than the probe


12


.




Referring to

FIG. 3

, the pull string


21


is arranged to pass through the two axial pierced holes


121


with an end thereof fixing with the stopper


22


and the other end thereof being fixedly attached by the puller


23


as soon as the zipper slider is assembled. Thus, the zipper slider can be moved along in a direction by puller


23


and in the other direction by stopper


22


.




Referring to

FIG. 4

, the stopper


22


shown in

FIG. 3

can be replaced by another puller


23


, which has either the same configuration as the puller


23


at the other end of the pull string


21


or a different configuration from the puller


23


, to perform the identical function as the zipper slider shown in

FIG. 3

does.




Referring to

FIG. 5

, the proboscis


12


with the hollow part


13


shown in

FIGS. 2

to


4


is replaced by a solid proboscis


12


with an axial pierced hole


121


passing through the entire proboscis


12


.




It is appreciated that the present invention has the probe at both ends thereof or an end thereof provide a puller to generate a rectilinear exerted force during the slider being pulled instead of the conventional puller, which having been used for long period of time and at an end thereof enclosing or surrounding the proboscis. Hence, the zipper slider of the present invention can lead to a better rectilinear pulling force directly in addition to promoting the function of marking out provided by the puller. It is not possible for the prior art, which has been applied in the conventional zipper slider for a long period of time, to reach the feature offered by the present invention.




While the invention has been described with reference to preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.



Claims
  • 1. A zipper slider comprising:a) a pull head including a zipper base with a proboscis member extending outwardly from one side of the zipper base, the proboscis member extending along an entire longitudinal length of the zipper base, the proboscis member having a longitudinal hole therethrough; and, b) a zipper pull including a pull string passing through the longitudinal hole in the proboscis member, and two pullers, one attached to each opposite end of the pull string such that the pullers are located outwardly of opposite longitudinal ends of the pull head.
  • 2. The zipper slider of claim 1 wherein one of the two pullers comprises a ball shaped stopper.
  • 3. The zipper slider of claim 1 further comprising a hollow between a portion of the proboscis member and the pull head.
  • 4. The zipper slider of claim 1 wherein at least one of the two pullers is plate shaped.
