Description

[Detailed description of the invention] This invention relates to a slider with a stop device for slide fasteners molded mainly from die gas or synthetic resin, and its purpose is to facilitate assembly and have a highly reliable stop function. An object of the present invention is to provide a slider with a stop device.

This invention was developed to achieve the above object, and its embodiment will be explained with reference to the drawings. In the figure, 1 is the body, 2 is the handle, 3 is the spring, and 4 is the cover. An abutment 5, a pair of guides 6, 6, and a cover support 8 are sequentially provided from the front end to the rear end on the upper piece 1a of the body 1, and a semicircular protrusion is formed on the abutment 5. 9 is formed, and a cover support hole 10 is bored in the front surface of the support base 5, as shown in FIG. The handle 2 has a shaft portion 11 at its front end. Also, spring 3
, one end of the band-shaped plate is bent downward in two stages, a stop claw 12 is formed at the rear end to protrude into the body 1 through the extraction hole 7, and the protrusion 9 is formed at the front end.
A long hole 13 is formed in the hole 13 to be engaged in a loosely fitted state, and a sub-piece 14 is provided in the middle part of the sub-piece 14 to straddle forward. A horizontal portion 17 is formed on the top. The cover 4 has cover support portions 8 of the fuselage at both ends.
The cover 4 has support legs 15, 15 that are engaged with the cover support hole 10, and has a notch 16 formed on both sides through which the handle 2 passes.
5 is engaged with the cover support part 8 and the cover support hole 10 to be fixed on the body 1, and the handle 2 is attached to the cutout part 15 of the cover 4 by placing the shaft part 11 between the support base 5 and the guide 6.
It is deeply supported. The spring 3 loosely fits its elongated hole 13 into the protrusion 9, and the stop claw 12 is inserted into the hole 7.
The horizontal part 17 enters the fuselage 1 through the fuselage 1.
It is placed on the top surface of the cover 4, and the sub-piece 14 is pressed against the inner surface of the cover 4.

This device has the above structure, and when the handle 2 is pulled, the stop claw 12 floats up from inside the body 1, and when the handle 2 is released, the stop claw 12 is moved inside the body 1 by the repulsive force of the spring 3. The action of plunging into the spring 3 is the same as that of the conventional one, but since the spring 3 of this invention is supported in a loosely fitted state on the protrusion 9 provided on the support 5, the spring 3 swings up and down. When the support part of the spring is fixed, unlike the case where the support part of the spring is fixed, the entire spring swings around the end of the support part as a fulcrum, instead of bending due to the concentrated load on one part, and the elastic function of the secondary piece is sufficient. It is something that is demonstrated. Therefore, since the entire spring is swung, the operating force applied to the pull tab 2 is lighter than that of a conventional fixed thigh, and the elasticity of the secondary piece is effectively utilized to provide a reliable stopping function. On the other hand, the spring 3 is supported on the support 5,
Since its support position is provided at a higher position than the body, even if the fastener element is tilted and the element is subjected to diagonally upward pressing force by the stop claw 12, there is a risk that the spring will float up and the front end support part will come off. Of course, the lock strength can be increased without any problem.
Since the support portion of the spring is not fixed, only a portion of the spring does not bend excessively even if a pressing force is applied. Furthermore, when assembling, after placing the handle on the body, the front end of the spring is loosely fitted into the protrusion while the shaft of the handle is crossed.
Since the horizontal part is mounted on the body, there is no interference between the spring and the shaft part of the handle, which prevents the spring from rolling, allowing for accurate assembly.

As described above, the slider with a stop device of the slide fastener according to this invention has a spring having a stop claw that protrudes into the body and is loosely fitted into the protrusion on the abutment provided in the body. It does not need to be bent into a conventional bow shape, making it easier to mold and can be formed accurately to the required dimensions, and it can be simply placed on the fuselage without being fixed during assembly, making it easy to assemble. It can be assembled by operation. Furthermore, since the spring is loosely fitted into the protrusion, the support portion is not bent when the spring is activated, so it is highly durable and provides a reliable stopping function over a long period of time.
