Description

[Detailed Description of the Invention] The present invention relates to an improvement of a releasable fitting stopper for a slide fastener.
To provide a releasable fitting tool for a slide fastener which can always guarantee smooth starting performance of a slider even when slight deviation occurs and can fix a box bar and a box with sufficient mounting strength. It is an object.

As shown in FIG. 7, the conventional separable fitting A
In the slide fastener B, a box E is fixed to a box rod D attached to the end of the stringer C, and an insert pin G attached to the end of the stringer F can be inserted into and removed from the box E. The slider I is inserted so that the left and right stringers C and F are engaged and separated.

The releasable fitting A of the conventional slide fastener B mentioned above has the lower end J of the box bar D brought into contact with the bottom M of the box bar insertion groove K of the box E, as shown in cross section in FIG. It has a structure in which a box pin D and a box E are fixed together, and an insert pin G is inserted into an insert pin insertion groove N of the box E. Therefore, if there is a slight deviation in the mounting position of the box pin D and the insert pin G with respect to the ends of the stringers C and F,
As shown in Fig. 8, connect the lower end O of the butterfly pin G to the box E.
When the insert pin is inserted until it comes into contact with the bottom P of the inserting groove N, a situation arises in which the engaging heads of the fastener elements Q and R interfere with each other, which has the disadvantage that the slider I starts unsmoothly.

The present invention has the structure described in the claims for utility model registration, so that even if the mounting position of the box rod and insert pin with respect to the stringer end is misaligned, after the box is fixed, the slider as described above This provides a separable fitting that does not cause any uneven starting.

The configuration of the illustrated example will be described below.

In the embodiment shown in FIG.
A butterfly pin 5 and a box pin 6 are fixed to the holder. A box 8 is fitted onto the insert pin 5 and the box pin 6 in a state where the fastener stringers 1 and 2 are engaged with the slider 7.

The aforementioned insert pin 5 of this embodiment is removably inserted into the insert pin insertion groove 9 of the box 8, and the length of the insert pin 5 is such that in the insertion position, the lower end 10 of the insert pin 5 is always The length is such that it can come into contact with the bottom 11 of the insertion groove 9.

Then, the box 8 is fixed to the box pin 6 inserted and arranged in the box pin fixing groove 12 of the box 8 while the insert pin 5 is inserted into the insert pin insertion groove 9 as described above. .

Then, in the above fixed state, the box bar fixing groove 1
The depth of the box bar fixing groove 12 and the length of the box bar 6 are selected so that a clearance H can be formed between the bottom 13 of the box bar 2 and the lower end 14 of the box bar 6.

That is, in this embodiment, the insert pin 5 is formed to be longer than the box pin 6 by a length L, and the fastening teeth 15 and 16 of the fastener stringers 1 and 2 are connected to the slider 7.
With the box 8 properly engaged with the insert pin 5, the box 8 is fixed to the box rod 6 with the lower end 10 of the insert pin 5 as a reference, and as described above, the left and right fastener stringers 1, 2, the insert pin 5, and the box rod Even if there is a slight deviation in the mounting position between the insert pin 5 and the box pin 6, the deviation in the relative position between the lower end 10 of the insert pin 5 and the lower end 14 of the box rod 6 based on this deviation, that is, the length L All changes are absorbed by the clearance H between the bottom 13 of the box bar fixing groove 12 of the box 8 and the lower end 14 of the box bar 6.
It is characterized by being constructed so that it can be erased.

FIGS. 2 to 5 show the separable fitting according to the embodiment shown in FIG.
First, the insert pin 5 and the box pin 6 shown in FIG. 3 are attached to the ends 3 and 4 of the fastener stringers 1 and 2 shown in FIG. It sticks like that. Next, the slider 7 is fitted into the fastener stringers 1 and 2 to which the insert pin 5 and the box pin 6 are fixed, and the fastener stringers 15 and 6 are fixed.
16 are engaged in the correct position to achieve the fastener chain state shown in FIG.

The box 8 is fitted onto the insert pin 5 and the box pin 6 in the state shown in FIG. 4, and the box 8 and the box pin 6 are fixed to form the structure shown in FIG. Assembling the release fitting to the fastener stringers 1 and 2,
This completes the fixation.

The three-member coupling structure of the insert pin 5, box rod 6, and box 8 shown in FIG. 5 is of course the structure already explained in detail with respect to FIG. At the position where the box 8 contacts the bottom 11 of the insert pin insertion groove 9, the box 8 is inserted into the box rod fixing groove 12 and fixed to the box rod 6 arranged, and the lower end 14 of the box rod 6 and the box rod fixing groove There is a clearance H between the bottom 13 of 12 and
is formed.

The length of this clearance H will vary slightly between individual slide fasteners if there is a slight deviation in the mounting position of the insert pin 5 and box pin 6 in each fastener stringer, but the length of the left and right fastener stringer 1,
The meshing position of the first coupling teeth 17 and 18 adjacent to the insert pin 5 and the box pin 6 in 2 is maintained at a constant position secured by the initial fitting and sliding of the slider 7.

FIG. 6 shows an insert pin 19 and a box 20 in another embodiment.
The locked state when inserted is shown in Figure 5-
It is shown as a cross section at the line position, and the butterfly pin 19
Step portions 21 and 22 are provided by making the lower part of the box thin, and the step portion 2 protrudes into the insert pin insertion groove 23 of the box 20.
4, 25 are provided, and when the insert pin 19 is inserted into the insert pin insertion groove 23, the step portions 21, 22 are aligned with the step portions 24, 25.
By coming into contact with 25, the insert pin 19 can maintain a constant insertion position with respect to the box 20. In this embodiment, the position of the insert pin 19 is maintained by the contact between the step portions described above, but the lower end 10 of the insert pin 5 and the bottom 11 of the insert pin insertion groove 9 in the embodiment shown in FIG. It has exactly the same effect.

The releasable fitting according to the present invention has the structure and operation described above, and even if there is a slight deviation in the attachment position of the insert pin and box pin to the left and right fastener stringers, the deviation will be corrected. This can be absorbed and erased by the clearance between the lower end of the box rod and the bottom of the box rod fixing groove in the box, so while the insert pin is kept at a constant position with respect to the insert groove, the box can be attached to the box rod. If it is fixed to the slider, it will always have the effect of guaranteeing smooth starting performance of the slider, and as in the past,
Since a structure in which the box and the box rod are fixed can be adopted, it has the effect of maintaining sufficient attachment strength between the box and the box rod.
