[0011]
According to a third aspect of the present invention, in addition to the configuration of the first aspect of the present invention, a closing body 3 which is disposed at the rear end of the detachable concealed slide fastener chain 1 and closes the rear end has a Y-shaped surface. This is a separation type hidden slide fastener formed by a reverse opening slider 23 provided with a guide groove 24 capable of guiding the chain 1 .
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of a separable type concealed slide fastener over in this invention will be described with reference to the drawings.
[0013]
First, an embodiment of a separation type hidden slide fastener will be described. The separation type hidden slide fastener shown in FIGS. 1 to 7 is roughly composed of a hidden type fastener chain 1, a slider 2, and a closing body 3, and the slider 2, the closing body 3 is formed of a thermoplastic resin or metal. ing.
[0014]
One fastener stringer 4 of the fastener chain 1 has a concealed type fastener bite 6 attached to one side edge of a fastener tape 5 in a continuous manner, and a fixing insertion rod 7 is fixed to an end thereof. Similarly, the other fastener stringer 8 has a concealed type fastener bite 10 attached to one side edge of the fastener tape 9, and an insertion rod 11 for insertion is fixed to the end thereof. The fastener bites 6 and 10 are formed of a monofilament or a single piece made of a thermoplastic resin, and may be made of a metal. Both the fixing insertion rod 7 and the insertion insertion rod 11 are conveniently formed from a molded article of a thermoplastic resin.
[0015]
In this embodiment, a box body 12 is used as the closing body 3, and the box body 12 is provided with a fastener stringer 4 having a T-shaped cross section which is vertically open at the center of the surface and penetrates vertically as shown in FIGS. A guide groove 13 for guiding is provided. On one side of the guide groove 13, a bottom wall 19 is opened to form an opening 14 through which the fastener 6 and the fixing insertion rod 7 can be inserted, and a lower half portion extending over the side wall 15, the upper wall 16, and the lower wall 17. Is provided with a recessed concave portion 18 at a deep portion of the groove. The bottom face on the other side of the guide groove 13 is formed with a closed bottom wall 19, and is formed in a form that can accommodate the insertion rod 11 provided in the fastener stringer 8.
[0016]
The fixing insertion rod 7 fixed to the fastener stringer 4 is in the shape of a square rod, and a single protruding ridge 20 protruding to the surface is formed in the lower half of the outer surface on the tip side, and is recessed in the box 12. The box body 12 is formed so that it can be fitted and locked in the recessed portion 18, and once fitted, the box body 12 cannot be detached from the fixing insertion rod 7. The size and thickness of the recess 18 and the ridge 20 may be small.
[0017]
In the embodiment shown in FIG. 7, a through hole 21 penetrating in the lateral direction is formed in the side wall 15 of the box body 12 in the concave notch 18, and the outer surface of the convex strip 20 of the fixing insertion rod 7 is formed in the lateral direction. The small projection 22 is provided so as to protrude, and the through hole 21 and the small projection 22 are formed so as to be able to snap-fit.
[0018]
As shown in FIG. 1, the box body 12 is inserted from the front end of the fastener bitter 6 in the fastener stringer 4, slides on the fastener bitter 6 to the rear end side to engage with the fixing insertion rod 7, and By inserting the slider 2 over the bite 6, a separation type hidden slide fastener with a separation fitting is completed, the slider 2 is brought into contact with the box 12, and the other fastener stringer 8 is inserted for insertion. After the rod 11 is inserted into the slider 2 and the box 12, the fastener chain 1 is closed or opened by sliding the slider 2. When the insertion rod 11 of the fastener stringer 8 is removed from the box body 12 and the slider 2 at the same time as the opening, the left and right fastener stringers 4 and 8 are completely separated and opened.
[0019]
Next, the separation type concealed slide fastener shown in FIGS. 8 to 12 is different from the form of the separation type concealed slide fastener of the previous example in that a reverse opening slider 23 is used instead of the box body 12 as the closing body 3. It is that you are.
[0020]
The reverse opening slider 23 is provided with a guide groove 24 for guiding the fastener chain 1 whose surface is opened in a Y-shape. The upper inner wall of the flange 25 which guides the fastener bite 6 on one side of the guide groove 24 and the opposite inner wall thereof The bottom 26 has a recessed recess 27 opposite the lower half of the tip.
[0021]
On the other hand, at the lower half of the outer surface of the fixing insertion rod 7 fixed to the tip of the fastener stringer 4, a convex portion 28 projecting only from the upper and lower surfaces is formed. It is formed so as to be able to abut, and the reverse opening slider 23 cannot be disengaged from the tip of the fixing insertion rod 7, but can slide on the inner fastener bite 6.
[0022]
As shown in FIG. 8, the reverse opening slider 23 is inserted from the front end of the fastener bitter 6 in the fastener stringer 4, slides on the fastener bitter 6 to the rear end side, and abuts with the fixing insertion rod 7. By inserting the slider 2 onto the fastener bite 6, the release type hidden slide fastener with the reverse opening slider is completed, the slider 2 is brought into contact with the reverse opening slider 23, and the other fastener stringer 8 is inserted for insertion. After the rod 11 is inserted into the slider 2 and the reverse opening slider 23, the fastener chain 1 is closed or opened by sliding the slider 2. If the insertion rod 11 of the fastener stringer 8 is pulled out of the reverse opening slider 23 and the slider 2 simultaneously with the opening, the left and right fastener stringers 4 and 8 are completely separated and opened.
[0023]
【The invention's effect】
Construction of open release concealed slide fastener over of the present invention is as described above, the following effects by this configuration.
[0024]
According to the first aspect of the present invention, a closed body for closing a rear end of a concealed type fastener chain is provided with a fixing insertion rod disposed at a rear portion of one fastener stringer and a side on which the fixing insertion rod is mounted. A fastener groove is formed so as to be insertable, and a guide groove 13 or 24 for a fastener stringer guide having an open surface is disposed in the closing body, and the closing body is prevented from falling off between the closing body and the fixing insertion rod. Is provided with a concave notch 18 or a concave recess 27 on the wall surface in the guide groove 13 or 24, and the convex ridge 20 or the convex 28 is formed on the outer surface of the fixing insertion rod. The following effects can be obtained by the protruding structure, in which the closing body slides on the fastener bite and is formed so as to be able to lock the concave notch and the convex ridge or the concave concave and the convex .
[0025]
