However, the horizontal holes are simply horizontal. You may pierce. In this case, the stopper rods 5a to 5f are pivotally attached to the both sides of the lateral hole in the main body, and the insertion portions 9a to 9f of the stopper rods 5a to 5f are
Since the pivot shafts 11a to 11f must be rotated within a certain range within the horizontal lateral hole, the vertical dimension of the lateral hole must be made larger than that in the illustrated embodiment. The lateral hole may be a hole that does not penetrate the main body, but it is easier to assemble each component because it is easier to pierce the main body from the front side (right end surface in FIG. 2) toward the rear side (left side in FIG. 2). Good.

In the embodiment shown in FIGS. 1, 5 (a) to 5 (d) and FIG. 6, the spring receivers 8a to 8f are rotated in either the left or right direction to rotate the springs with respect to the main bodies 2a to 2f. By vertically moving the receiving bodies 8a to 8f within a certain range, the elastic force of the coiled springs 7a to 7f for urging the insertion portions 9a to 9f of the stopper rods 5a to 5f upward can be adjusted. As a spring, it goes without saying that a leaf spring may be used instead of the coiled spring. However, when using a leaf spring, 8e in Fig. 5 (d) or
It may be necessary to use a spring bearing as shown at 8f in FIG.

In the hanging sliding door, if a stopper for preventing book bounce is attached to the end of the upper rail C, when the door is closed, for example, as shown in FIG. The convex arcuate upper end surface of the stopper engaging portion J between the children D contacts the convex arcuate surface of the catching portion 12 of the stopper rods 5a to 5f, and the stopper engaging portion J has coil springs 7a to 7e. Push up the catch 12 against the elastic force of the stopper rod (the part shown by the chain line in Fig. 1), and push the stopper rod in that direction.
5a to 5f are rotated within a certain range about the pivot shafts 11a to 11f. When the stopper engaging portion J passes over the tip of the catch portion 12 of the stopper rods 5a to 5f, the elastic force of the coiled springs 7a to 7f causes the stopper rods 5a to 5f.
5f rotates in the opposite direction to the initial direction, and as shown by the solid line in FIG. 1, the catching portion 12 presses the stopper engaging portion J by the elastic force of the springs 7a to 7f, and the runner A moves to the upper rail C It is forced to stop in the groove. Therefore, the door a does not hit the pillar and rebound.

Further, when the spring receivers 8a to 8f are rotated in either the left or right direction to move the spring receivers 8a to 8f up and down with respect to the main bodies 2a to 2f within a certain range, the stopper rods 5a to 5f are inserted. By adjusting the force of the springs 7a to 7f for urging the portions 9a to 9f, the force with which the catch portion 12 of the stopper rods 5a to 5f engages with the stopper engaging portion J can be adjusted.

In the embodiment, the runner in which the pair of trochanters D and D rotate in the two running paths K and K in the one upper rail C is taken as an example, and the pair of trochanters D and D The case where one stopper rod is engaged with one stopper engaging portion J located between D has been described, but for a runner provided with two stopper engaging portions J, for example, Various modifications can be made such as providing two stopper rods for the main body in the present invention.

[0029]

According to the invention as set forth in claim 1, since the stopper rod pivotally attached to the main body is urged by the elastic force of the spring, the stopper rod is urged by the elastic force of the spring when the door is closed. The catch portion of the rod firmly holds the stopper engaging portion and can completely prevent the door from bouncing. Further, since the spring receiving body attached to the main body can make the elastic force of the spring constant, the force with which the catch portion of the stopper rod engages with the stopper engaging portion is
It can be static and the bounce prevention stopper can be durable.

According to the second aspect of the present invention, by vertically moving the spring receiving member with respect to the main body, the elastic force of the spring can be adjusted, so that the stopper engaging portion of the catch portion of the stopper rod can be adjusted. The engaging force can be adjusted according to the size and weight of the door.
