という問題もあつた。 As is well known, a reverse-opening slide fastener is equipped with two sliders (upper and lower) so that it can be opened from both directions. In this type of slide fastener, a release tool is attached to the fastener stringer and includes a stopper mechanism that guides the lower slider and holds the lower slider so that it does not fall off. Conventionally, such a stopper mechanism has been known in which the upper slider and the lower slider are constructed separately, and a locking recess is formed in the lower slider so that the locking convex portion of the release tool is locked with the stopper mechanism. However, this method requires machining of the slider and requires two types of sliders to be prepared, which has the disadvantage that manufacturing is troublesome and expensive. On the other hand, as shown in Fig. 5, as a stopper mechanism when the slider is used with the same upper and lower sliders without any special processing, the release tool 1 has an engagement wider than the gap between the flange 3 of the slider 2 and the diamond 4. A device is known in which a locking portion 5 is formed and the flange 3 and the diamond 4 are locked by the wedge action of the locking portion 5. However, this increases the width of the release tool 1, which is not only unfavorable in appearance, but also because it is locked to the slider by a wedge action, it is difficult to remove when opening the fastener, making it difficult to start the slider, and moreover, a large load is applied. The disadvantage is that it can easily fall out if it gets stuck. In order to prevent such slippage, a protruding piece is known to be formed so as to protrude outward from the locking part 5, but it becomes wider. The disadvantage of poor starting performance due to the wedge effect remains unresolved. If the release tool is wide, it not only causes problems in appearance, but also makes it difficult to sew the fastener completely to the bottom end, as the guide member is likely to hit the sewing foot and be pushed out when sewing the fastener onto clothing etc. using a sewing machine. There was also the issue of.

To provide a slide fastener with a reverse opening release tool which can minimize the width of a guide member, can securely lock a slider, does not come off even under a large load, and has good startability of the slider.

In FIG. 1, 10 and 10' are fastener stringers, and elements 12 and 12 are attached to tapes 11 and 11'.
are sewn together with sewing thread 13. Synthetic resin films 14, 14' for reinforcing and preventing fraying are welded to the lower ends of the tapes 11, 11',
Release members 15, 15' are attached by injection or pressure molding of synthetic resin so as to sandwich the films 14, 14' and tapes 11, 11'. Each release tool 15,
Guide portions 17, 17' are formed on the inner edge of the guide 15' and protrude more toward the surface than the outer edges 16, 16'. The outer end edge 18 of the guide portion 17 of one of the releasing tools 15 has a concave curved surface 21 along the inner surface of the flange 20 of the lower slider 19. A groove 22 is formed on the inner surface of one of the release tools 15, into which a tongue piece 23 formed on the inner surface of the other release tool 15' is fitted.

８から抜け出さないようにするためである。 A guide portion 1 is provided at the lower end of the one releasing tool 15.
A horizontal L-shaped stopper 25 is provided that protrudes to the side of the stopper 7 and has a rising portion 24 at the side end.
Therefore, when the lower slider 19 is locked by the stopper 25 as shown in FIG. Together with this, the lower slider 19 is stably positioned, and when a large load is applied to the lower slider 19, the flange 20 of the rising portion 24 is deformed outward (toward the right in FIG. 1). It plays the role of preventing The stopper 25 is shown in FIGS. 3 and 4.
As shown in the figure, its surface is lower than the guide portion 17 and higher than the outer edge 16. The lower slider 19 has the same structure as the upper slider (not shown).
When the slider 19 is moved from the state shown in FIG. 2 to the lowest position shown in FIG. 1, the lower end of the flange 20 of the slider 19 is stopped by the stopper 25. The concave curved surface of the guide portion 17 is in contact with the inner surface of the flange 20 of the slider 19 in the slider locked state shown in FIG. There is. Therefore, the releasing tool 15 is not wedged between the flange 20 and the diamond 26, and the diamond 26 is not in contact with the guide portion 17, so that the lower slider 19 can be started easily. . Further, when the inner edge of the lower end of the guide portion 17 is in contact with the side surface of the diamond 26 as shown in FIG. The groove portion 27 of 25 is positioned substantially opposite the lower end of the flange 20. Therefore, when the slider 19 is pulled down from this state, the guide portion 17
When the flange 20 is removed from the diamond 26, the lower end of the flange 20 fits into the groove 27 of the stopper 25 almost at the same time, and the slider can be stopped reliably. Width dimension L 1 of the lower end of the release tool 15 (rising portion 24 of the stopper 25 from the inner edge of the guide portion 17
(to the outer surface of the diamond 26) is larger than the distance L2 between the branch paths 28 of the slider 19 (the shortest distance between the inner wall surface of the flange 20 and the side surface of the diamond 26). This means that the release tool 15 is the branch path 2.
This is to prevent it from falling out of 8.

ため外観が良好である等種々の効果がある。 As described above, according to the present invention, a stopper is provided at the lower end of the guide portion that protrudes laterally and has a rising portion at the side end, so that the flange of the slider is reliably locked by this stopper, and the flange is fixed on the inner surface of the flange. In combination with the close contact of the concave curved surface of the guide part, the lower slider is stably positioned and plays the role of a box body in a slide fastener with a releasable fitting. Even when a load is applied, the slider is prevented from moving in the lateral direction and is reliably prevented from coming off the release tool. In addition, since the release tool is separated from the diamond of the slider when the slider is in the locked state, there is no wedge effect and the slider has good startability.
Furthermore, since the width of the guide portion can be minimized, there are various effects such as a good appearance.
