ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a zipper pull of a slider for slide fastener for use behind a fly of mainly a front-open cloth such as a training wear and jacket, and more particularly to a zipper pull of a slider for slide fastener, the zipper pull being formed of resilient body and urged so as to be fallen onto a slider body, thereby maintaining a stabilized state in which the zipper pull does not swing freely when the cloth is worn.
2. Description of the Related Art
As shown in
FIG. 16
, a conventional slider zipper pull
2
′ is formed of resilient member
37
′ fixed to a connecting body
3
′ supported pivotally in the same direction as a sliding direction of the slider body
1
′. The resilient member
37
′ is capable of moving and holding the resilient member
37
′ itself and the connecting body
3
′ elastically in the longitudinal direction relative to substantially the same plane as the slider at their locking position. The connecting body
3
′ comprises a first end portion
3
′-
1
which is supported pivotally on the slider and a second end portion
3
′-
2
fixed to the resilient member
37
′. The resilient member
37
′ has a free end portion
27
′ which is disposed at a position apart from the second end portion
3
′-
2
. The free end portion
27
′ of the resilient member
37
′ and the second end portion
3
′-
2
of the connecting body
3
′ are located oppositely each other at both ends of the slider at a locking position of the slider. Further, the first end portion
3
′-
1
of the connecting body
3
′ is disposed between the second end portion
3
′-
2
and the free end portion
27
′ of the resilient member
37
′. Such a slider for slid fastener has been disclosed in U.S. Pat. No. 5,101,538.
According to a slider for slide fastener disclosed in U.S. Pat. No. 2,263,393, as shown in
FIG. 17
, a pin
18
″ is attached in a longitudinal direction in the center of a top face of a slider body
1
″ of the slider so that two sheet-like zipper pulls
2
″ are supported pivotally by this pin
18
″ so as to be capable of rotating to the left and right. The sheet-like zipper pulls
2
″ are formed so as to be always fallen onto the slider body
1
″ by a coil spring
19
″ inserted through the pin
18
″. A locking pawl
11
″ is provided on a proximal portion of the sheet-like zipper pull
2
″ and when the slider is not moved, the locking pawl
11
″ is fitted in between fastener elements to prevent the slider from sliding. When it is intended to move the slider, the right and left zipper pulls
2
″ are raised so as to escape the locking pawl
11
″ from between the fastener elements. Consequently this slider can be slid.
In case of the zipper pull
2
′ of a slider for slide fastener shown in
FIG. 16
, when the slider is slid in the longitudinal direction to close the slide fastener, the ring-like zipper pull
2
′ of resilient member
37
′ has to be pulled forward. At that time, the resilient member
37
′ must be turned substantially at 180° between a free end portion
27
′ and a second end portion
3
′-
2
fixed to the connecting body
3
′ and then pulled forward. On the other hand, to separate and open the slide fastener, the resilient member
37
′ has to be also turned substantially at 180° between the free end portion
27
′ and the second end portion
3
′-
2
fixed to the connecting body
3
′ and then pulled backward. Therefore, the ring-like resilient member
37
′ may be damaged because a turning load is applied to the second end portion
3
′-
2
fixed to the connecting body
3
′, so that this zipper pull
2
′ cannot bear a long term use.
In case of the zipper pull
2
″ of the slider for slide fastener shown in
FIG. 17
, the zipper pull
2
″ is metallic, so it is hard and not flexible. Because of it, there is a feeling of discomfort when it is used in a training wear, jacket and the like. Particularly, this zipper pull
2
″ is not suitable for an opening of cloth which is kept in contact with the skin. Further, because the right and left zipper pulls
2
″ have to be always raised so as to slide the slider, there is such a problem that an opening/closing operation for this slide fastener is troublesome.
SUMMARY OF THE INVENTION
The present invention has been achieved in views of the above described problems. An object of the invention is to provide a zipper pull of a slider for slide fastener capable of opening or closing the slide fastener when the zipper pull of resilient body mounted to a slider body with a connecting body is rotated with a slight rotation and then pulled in a direction perpendicular to a sliding direction of the slider or in a forward direction. More specifically, the main object is to provide such a zipper pull of a slider for slide fastener, wherein, when the slider is opened or closed, the resilient body does not have to be twisted so much, so that the zipper pull is protected from a damage and capable of bearing a long term use and also kept pressured in a contact with the slider body in a stabilized condition without swinging, thereby providing a user with no discomfort.
Another object of the invention is to provide a zipper pull of resilient body suitable for various types of the sliders by specifying a configuration of the zipper pull formed of resilient body to be mounted on the slider body, for example, to a shape of half-annulus, annulus, strip, sheet or the like.
And another object of the invention is to provide various kinds of zipper pulls of resilient body formed on the slider body easy to grip and handle when the slider is slid.
Also another object of the invention is to provide a connecting body for the zipper pull capable of holding the zipper pull of resilient body on the slider body in a stabilized condition with a good appearance by specifying the shape of the connecting body used for mounting the zipper pull onto the slider body and forming the shape of the connecting body to a shape which facilitates the handling thereof and further is capable of fixing the zipper pull of resilient body firmly.
And a further object of the invention is to provide a slider with an automatic locking mechanism having the zipper pull of resilient body and being produced easily by specifying the shape of the connecting body to adapt the zipper pull of resilient body to a slider having various types of the automatic locking mechanisms.
It is also another object of the invention to provide a zipper pull of resilient body which can be produced easily by specifying material of various types of zipper pulls of resilient body.
To achieve the above object, according to the main aspect of the invention, there is provided a zipper pull of a slider for slide fastener, wherein an mounting portion for mounting a zipper pull is provided on a top face of a slider body of a slider; an annular connecting body having an appropriate shape is disposed to the mounting portion; a lateral bar is provided in the center of the connecting body; the lateral bar is mounted on the mounting portion such that it is inserted therethrough; the zipper pull formed of resilient body is fixed to front and rear ends or only a front end of the connecting body so as to form fixing portions; and the zipper pull formed of resilient body is always urged to be fallen on a surface of the slider body, that is, a top face or side face of the slider body. Particularly if the connecting body is used in a slider with an automatic locking mechanism, the locking mechanism can be operated by tilting the connecting body slightly in the longitudinal direction or in the width direction. The condition mentioned here that the zipper pull is fallen onto the surface of the slider body means that the zipper pull is disposed substantially pa
