ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a releasable bottom end stop for slide fastener, more specifically, to a releasable bottom end stop, wherein a insert pin of an ordinary type releasable bottom end stop comprised of a box, a box pin and the insert pin or an inverse-opening type releasable bottom end stop comprised of an inverse-opening slider, a box pin and an insert pin is improved, so as to achieve smooth separating and fastening operations.
2. Description of the Related Art
As a conventional releasable bottom end stop, Japanese Utility Model Application Publication No. 63-31607 has disclosed a releasable bottom end stop in which, as shown in
FIG. 11
, an inner edge of an end portion on a fastener element
18
′ side of a box pin
3
′, that is, an edge portion on a fastener tape side is cut out so as to be chamfered in the form of a slope
6
′.
Further, in a releasable bottom end stop disclosed in Japanese Patent Application Laid-Open No. 11-178615, as shown in
FIG. 12
, a corner of a half outer edge portion on a front end side of its insert pin, which a locking pawl
25
″ of a slider
5
″ comes into contact with, is cut out in the form of a slope so as to form a slope
6
″ and then, continuously to that slope
6
″, an avoiding portion, which avoids engagement of the locking pawl
25
″, is formed by cutting out other half edge portion up to a proximal portion of a stop portion for the fastener element
18
″, such that its inner portion forms a slope
6
″ and its outer portion forms a horizontal face
30
″.
In the above-described releasable bottom end stop shown in
FIG. 11
, when the insert pin
4
′ is inserted into a box
2
′ to which the box pin
3
′ is fixed, it comes that the insert pin
4
′ is inserted in a condition that the slider
5
′ is inclined and in contact with the box
2
′. Because the locking pawl
25
′ located on the box pin
3
′ side is moved to a normal position of the box pin
3
′ together with the slider
5
′, the edge portion of the box pin
3
′ is cut out so as to facilitate the moving of the locking pawl
25
′. Therefore, this releasable bottom end stop is not applicable when the locking pawl
25
′ exists on the insert pin
4
′ side, particularly, for the insert pin
4
′ of the inverse-opening type releasable bottom end stop.
The releasable bottom end stop shown in
FIG. 12
is an ordinary type releasable bottom end stop formed of the box
2
″, the box pin
3
″ and the insert pin
4
″. Thus, this is not applicable for an inverse-opening type releasable bottom end stop employing an inverse-opening slider instead of the box
2
″. That is, this releasable bottom end stop is incapable of holding the slider disposed at an end of a fastener chain in a stable condition. Further, there is no function of raising the locking pawl
25
″, so that the slider
5
″ cannot be started up smoothly even in case that an insert pin
4
″ of the ordinary type releasable bottom end stop is used.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been achieve in views of the above-described problem and an object of the invention is to provide a releasable bottom end stop for slide fastener having an insert pin suitable for not only an ordinary type releasable bottom end stop comprised of a box, a box pin and the insert pin, but also an inverse-opening type releasable bottom end stop comprised of an inverse-opening slider, a box pin and the insert pin. More specifically, the insert pin may be inserted smoothly into a slider having an automatic stop mechanism or a semi-automatic stop mechanism containing a locking pawl. And the releasable bottom end stop is provided, wherein the slider is maintained stably, the insert pin of the ordinary type or inverse-opening type releasable bottom end stop allows the slider to be started up smoothly and ensuring an excellent function is ensured.
Another object of the invention is to provide a releasable bottom end stop for slide fastener capable of improving the function of the releasable bottom end stop by applying a specific form to the insert pin of an ordinary type releasable bottom end stop comprised of the box, the box pin and the insert pin.
Still another object of the invention is to provide a releasable bottom end stop for slide fastener capable of improving the function of the releasable bottom end stop by applying a specific form to the insert pin of the inverse-opening type releasable bottom end stop comprised of the inverse-opening type slider, the box pin and the insert pin.
Further object of the invention is to provide a releasable bottom end stop for slide fastener capable of expanding a range of the usage of the releasable bottom end stop by forming an insert pin each having a specific form applicable for various types of the slide fasteners.
And further object of the invention is to provide a releasable bottom end stop for slide fastener capable of maintaining the inverse-opening type slider used for the inverse-opening type releasable bottom end stop stably, starting up the inverse-opening type slider smoothly and improving the function of a separation and opening operation of the inverse-opening.
Still further object of the invention is to provide a releasable bottom end stop for slide fastener capable of exerting an excellent function of the separation and fastening operation by providing the box pin of the inverse-opening type releasable bottom end stop with a specific form.
To achieve the above-described objects, according to the invention, there is provided a releasable bottom end stop for slide fastener, wherein an insert pin thereof has a slope for raising a locking pawl of an automatic stop mechanism or a semi-automatic stop mechanism of an inverse-opening slider or a slider when the insert pin is inserted into the inverse-opening slider or the slider, the slope being provided to extend from a front end of the surface of the insert pin to a proximal end thereof. Consequently, the insert pin of the ordinary type or inverse-opening type releasable bottom end stop can be inserted smoothly into the slider or the inverse-opening type slider having the automatic stop mechanism or semi-automatic stop mechanism. Further, the slider can be started up smoothly thereby exerting an excellent function as the releasable bottom end stop.
Preferably, the insert pin of the ordinary type releasable bottom end stop comprised of a box, a box pin and the insert pin has the slope for raising the locking pawl of the slider having the automatic stop mechanism or the semi-automatic stop mechanism provided on a fastener chain. Consequently, the mechanism having such an excellent releasable bottom end stop function can be applied to the insert pin of the ordinary type releasable bottom end stop.
Alternately, the insert pin of an inverse-opening type releasable bottom end stop comprised of an inverse-opening slider, the box pin and the insert pin has the slope for raising the locking pawl of the slider having the automatic stop mechanism or the semi-automatic stop mechanism provided on the fastener chain. Consequently, the mechanism having such an excellent releasable bottom end stop function can be applied to the insert pin of the inverse-opening type releasable bottom end stop. Further, in a conventional inverse opening slider, a special slider, wherein the locking pawl does not protrude into an insertion route through which the insert pin is inserted into the guide groove, is used. On the contrary, in this invention, such a special slider is not needed, that is, a usual slider can be used.
Preferably, the slope for raising the locking pawl of the automatic stop mechanism or the semi-automatic stop mechanism and being formed on the insert pin of the releasable bottom end stop is provided obliquely in the entire width of the surface of the insert pin. Consequently, this releasable
