ABSTRACT:
BACKGROUND OF INVENTION
1. Field of the Invention
The present invention relates to separable bottom end stop assembly of a slide fastener. More particularly it relates to separable bottom end stop assembly of a lateral-inserting type slide fastener in which one of the separable bottom end stops attached to a lower end of a fastener stringer is a male member and the other is a female member, and after the male member and the female member are engaged from both surfaces of the fastener surface by a snapping system, the male member and the female member are caused to join up against each other from the transverse direction of the fastener, thereby fitting the fastener stringer inside the slider.
2. Prior Art
In the separable bottom end stop assembly of a slide fastener which has been used in the past, a box pin and a box are attached to an end portion of one of left and right fastener stringers and an insert pin is attached to the other fastener stringer. When the left and right fastener stringers are to be closed, the slider is slid so as to contact the box, and then the insert pin is inserted into the element guide groove of the slider. Next, after the insert pin is inserted into the box, the slider is pulled upwards and caused to slide and the closing operation is thereby carried out. However, in this type of separable bottom end stop assembly in which the insert pin must be inserted in the box, the insertion operation is extremely difficult for children and elderly people.
One known separable bottom end stop assembly which can be operated simply is a lateral-inserting type in which a male member having a projecting pin and a female member having a socket are provided at an end portion of the right and left fastener stringers so as to be engaged with each other, and the fastener stringer is fit-inserted from the side of the slider and thereby closed. This lateral-inserting type separable bottom end stop is disclosed, for example, in the specification of U.S. Pat. No. 4,139,927, which is shown in FIG.
21
. In the disclosed separable bottom end stop, an incline surface having a screw-like configuration is provided at a portion of the periphery of each of the pin
110
and socket
112
of the male member
107
and the female member
108
which are provided at end portions of the left and right fastener stringers
102
,
102
. When the right and left fastener stringers
102
,
102
are rotated about the pin
110
, the female member
108
moves toward the pin
110
of the male member
107
, so that the engagement and separation operation of the male member
107
and the female member
108
can be carried out.
In the separable bottom end stop of the above-described slide fastener which is shown in
FIG. 21
, when the right and left stringers
102
,
102
are rotated in the closing direction around the pin
110
after the pin
110
and the socket
112
are engaged, it is necessary to lead one of the fastener stringers
102
,
102
into the slider
103
using the hands in order to fit-insert the fastener stringer
102
into the slider. This is because the screw-shaped incline surface is formed at a fixed angle. Further, in order to rotate the fastener stringer
102
in the opposite direction and separate the pin
110
from the socket
112
, the fastener stringer
102
must be rotated to a great extent, or else the fastener stringer
102
at the socket side must be twisted and detached. Thus there is the problem that the engagement and separation operations are extremely difficult.
SUMMARY OF INVENTION
The present invention obviates the aforementioned problems and has a principal object to provide a lateral-inserting type separable bottom end stop assembly of a slide fastener in which the engagement and separation operations are extremely simple and particularly, children and elderly people can perform the operation of closing of the left and right fastener stringers in a simple manner. That is to say, it is a principal object of the present invention to provide a separable bottom end stop assembly of a slide fastener in which the male member and the female member comprising the separable bottom end stop assembly can be engaged from both front and back directions, and by pulling together the male member and the female member and pressing both front and back surfaces thereof, the fastener stringers are closed easily due to cam mechanism, thereby causing initial movement of the slider, and in which separation of the left and right fastener stringers can be easily prevented, and further the separation and release of the left and right fastener stringers can be easily carried out.
Still another object of the invention is to provide a separable bottom end stop assembly of a slide fastener which automatically, speedily and accurately guides an insert plate to an inner portion of the slider which is held by a holding portion which opposes the insert plate.
Still another object of the invention is to provide a separable bottom end stop assembly of a slide fastener in which by specifying the configuration of a sliding surface of slide plate of the male member or the female member, the operation can be effective and accurate, and the separation of the male member and the female member can be carried out simply.
Still another object of the invention is to provide a separable bottom end stop assembly of a slide fastener in which by specifying the surface configuration of the slide plate of the male member or the female member, the engagement and separation of the male member and the female member and the opening and closing of the fastener chain can be carried out smoothly and easily.
Still another object of the invention is to provide a separable bottom end stop assembly of a slide fastener in which by specifying the surface shape of the male member or the female member, the operation of initial movement of the slider attached at the separable bottom end stop assembly can be started simply and reliably using the finger tips.
Still another object of the invention is to provide a separable bottom end stop assembly of a slide fastener in which by specifying the configuration of the slider which is adapted to be mounted to the fastener chain, even children and elderly people can carry out the engagement and separation operation smoothly while the male member and the female member are visible.
The above described objects can be attained by a basic feature of the present invention, that is, a lateral-inserting type separable bottom end stop assembly which comprises a male member and a female member which are engageable with and releasable from each other. The male member is provided with a first slide plate from which an engagement leg portion projects, while the female member is provided with a second sliding plate in which an engagement hole is formed to be fitly engaged with the engagement leg portion. First and second sliding surfaces are formed respectively at the peripheries of the engagement leg portion and the engagement hole. At the time of engagement, the male member and the female member are rotatable relatively with the first and second sliding surfaces thereof being in slide contact with each other. Each of the first and second slide surfaces is formed with a steep incline surface and a gentle incline surface. The steep incline surface and the gentle incline surface serve to automatically advance an insert plate which is disposed at one of the male member and the female member to an inside of a slider which is held by a holding portion which is disposed at the other of the male member and the female member when the first and second slide plates are pressed from both surfaces thereof.
With such structure, by simply pressing the first and second slide plates of the male member and the female member which are in an engaged state from the front and the back, the insert plate can be automatically and speedily moved towards the slider which is held at the holding portion due to the action of the cam. Consequently the operation can be carried out easily even by children and elderly people or by
