Abstract

The present invention intends to provide a zipper pull of a slider for slide fastener formed of- resilient body on which no unreasonable force is applied when the fastener is opened or closed and which is always kept in a stabilized condition that it is urged to be fallen onto a slider body without swinging freely. A yoke which is a zipper pull mounting portion is mounted on a top face of a slider body. A half-annular shaped zipper pull formed of resilient body is fixed to lateral bars at front and rear ends of a rectangular connecting body longer than the slide body. A lateral bar is provided in the center of the connecting body and inserted through an automatic locking pawl lever incorporated in the yoke. Neck portions are provided in the vicinity of a fixing portion at the front and rear ends so that the zipper pull is elastically deformable easily. A grip portion is provided at a position apart from the fixing portion so that the zipper pull is easy to grip. Further, a feature of the zipper pull of this invention is that a central portion to be disposed on the slider body of the connecting body is low while the sides of the fixing portions on both ends are located higher and extended horizontally with a step. Consequently, when the zipper pull is brought up slightly, the locking pawl lever can be raised so that the slider can be slid. The zipper pull is always kept in such a stabilized condition that it is fallen to the slider body.

Claims

1. A slider for a slide fastener comprising a zipper pull mounting portion provided on a top face of a slider body of the slider;

a connecting body disposed such that the connecting body traverses the top face of the slider body;

at least one lateral bar provided in a center portion of the connecting body;

said lateral bar being mounted on the mounting portion such that it is inserted therethrough; and

a zipper pull formed of resilient body that is fixed to front and rear ends of the connecting body so as to form a plurality of fixing portions;

wherein said zipper pull is always urged to be fallen on a surface of the slider body.

2. A slider for a slide fastener according to claim 1, wherein the zipper pull is formed in a substantially annular shape, wherein the connecting body includes lateral bars provided at both the front end and the rear end of the connecting body, wherein end portions of the zipper pull are fixed horizontally to the lateral bars provided at the front and rear ends of the connecting body so as to form the plurality of fixing portions.

3. A slider for a slide fastener according to claim 1, wherein the zipper pull is formed in a substantially annular shape, wherein the connecting body includes lateral bars provided at both the front end and the rear end of the connecting body;

mounting tongues are provided at end portions of the substantially annular shaped zipper pull; and

the mounting tongues are fixed horizontally to the lateral bars provided at the front and rear ends of the connecting body so as to form the plurality of fixing portions.

4. A slider for a slide fastener according to claim 1, wherein a neck portion is formed in the vicinity of the fixing portions where the zipper pull is fixed to the connecting body.

5. A slider for a slide fastener according to claim 1, wherein the zipper pull comprises a grip portion such that a space is expanded obliquely forward of the fixing portions where the zipper pull is fixed to the connecting body.

6. A slider for a slide fastener according to claim 1, wherein the zipper pull comprises a grip portion having an expanded diameter provided at a portion apart from the fixing portions where the zipper pull is fixed to the connecting body.

7. A slider for a slide fastener according to claim 1, wherein the connecting body for fixing the zipper pull is formed in a rectangular shape longer than the mounting portion and said connecting body is disposed longitudinally with respect to the mounting portion.

8. A slider for a slide fastener according to claim 1, wherein the connecting body for fixing the zipper pull comprises lateral bars such that the central portion of the connecting body, which is disposed longitudinally on the top face of the slider body, is low while the front end and the rear end of the connecting body are located higher and extend horizontally with a step.

9. A slider for a slide fastener according to claim 1, wherein a lateral bar is provided at the front end of the connecting body for fixing the zipper pull to form one of the plurality of fixing portions, wherein a flat mounting piece extending inward is provided on the lateral bar provided at the front end of the connecting body such that it protrudes from the lateral bar, and wherein said mounting piece is buried in the zipper pull.

10. A slider for a slide fastener according to claim 1, wherein the lateral bar provided in the center portion of the connecting body is inserted through an automatic locking pawl lever incorporated in a yoke mounted on the top face of the slider body such that the automatic locking pawl lever is capable of being raised.

11. A slider for a slide fastener according to claim 1, further comprising a second lateral bar provided in the center portion of the connecting body spaced by an interval with the at least one lateral bar provided in the center portion of the connecting body, wherein, of these two lateral bars provided in the center portion of the connecting body, one lateral bar is inserted through an automatic locking pawl lever incorporated in a yoke mounted on the top face of the slider body and the other lateral bar is inserted through a sliding body capable of sliding within the yoke such that the automatic locking pawl lever is capable of being raised.

12. A slider for a slide fastener according to claim 1, wherein the at least one lateral bar provided in the center portion of the connecting body is fitted freely movably in a sliding opening provided horizontally on a bottom end of each of both side walls of a yoke mounted on the slider body;

the yoke incorporates an automatic locking pawl lever having a spring piece protruded on a top portion thereof, a locking pawl provided on a bottom end, a protruded portion capable of engaging freely detachably with a cut-out portion of the slider body and a cam face provided between the locking pawl and the protruded portion; and

the at least one lateral bar provided in the center portion of the connecting body is kept in contact with the cam face so that the automatic locking pawl lever is capable of being raised.

13. A slider for a slide fastener according to claim 1, wherein the zipper pull of resilient body is formed of natural rubber, synthetic rubber or thermoplastic elastomer.

14. A slider for a slide fastener according to claim 1, wherein the zipper pull comprises a grip portion having a large thickness provided at a portion apart from the fixing portions where the zipper pull is fixed to the connecting body.

15. A slider for a slide fastener according to claim 1, wherein the connecting body for fixing the zipper pull is formed in an elongated circular shape longer than the mounting portion and said connecting body is disposed longitudinally with respect to the mounting portion.

16. A slider for a slide fastener according to claim 1, wherein a lateral bar is provided at the front end of the connecting body for fixing the zipper pull to form one of the plurality of fixing portions, wherein a flat mounting piece extending outward is provided on the lateral bar provided at the front end of the connecting body such that it protrudes from the lateral bar, and wherein said mounting piece is buried in the zipper pull.
