[Detailed description of the device]

[0001]

[Field of Industrial Application] There are two types of folding doors: a fixed opening / closing method in which one end is held and fixed so that it cannot be moved, and a opening / closing method in which the door can be opened or closed from either the left or right side. The present invention is a dual-purpose folding door that can be switched between a fixed opening type and an open opening type as needed .
Of runner stopper .

[0002]

2. Description of the Related Art A fixed open / close type folding door is known, for example, from Japanese Utility Model Publication No. 62-10384. There, a stopper metal fitting is screwed to the opening edge of the guide rail, and the metal fitting blocks the running area of the runner body to prevent the runner on the suspension base side from moving. FIG. 8 shows a conventional folding door that is used by switching between a fixed open / close system and an open / close system. This is to hold and fix the runner 43 by a runner stopper 42 provided on the inner surface of the upper wall of the guide rail 41. When the runner 43 is pushed into the lower surface of the runner stopper 42, the runner stopper 42 holds the roller 44 in pressure contact. It can be used as a fixed opening / closing method, and can be used as an opening / closing method when the roller 44 is pulled out from the runner stopper 42. The runner stopper 42 is a pressed product made of a leaf spring and is attached to the guide rail 41 with a screw 45. 46 is a door.

[0003]

In the above-mentioned folding door of the dual type, the runner stopper 42 is fixed by the screw 45 to the guide rail 41.
The position of the runner stopper 42 cannot be adjusted because it is directly fixed to the. Therefore, it is not possible to cope with variations in the dimensions of the door frame, and for example, when used as a fixed opening / closing type folding door, a large gap may occur between the side edge of the door 46 on the hanging side and the door frame. . Since the roller 44 rolling on the rail is fixed and the roller 44 is held and fixed by the runner stopper 42 circumscribing the peripheral surface of the rail 44, when the roller 44 is used as a fixed opening / closing type folding door, the runner is opened / closed as the door 46 is opened / closed. It is easy for 43 to move freely, and the door 46 cannot be opened and closed smoothly. Furthermore, when the door 46 is closed,
The preceding roller 44 may pass through the runner stopper 42 by excessive force. In this case, since the side edge of the door 46 that is being closed abuts and interferes with the door frame, an unreasonable force acts on the door 46, the door frame, and the runner 43.

An object of the present invention is to attach a runner stopper to a guide rail so that the position of the runner stopper can be adjusted freely.
It is possible to change the holding position of the runner according to the variation in the dimensions of the door frame, and thereby obtain a dual-use folding door with excellent workability. Another object of the present invention is to hold and fix the runner by fixing the runner body that moves linearly along the guide rail as a fixing target, so that the runner can be held and fixed reliably, and thus the door can be smoothly opened and closed. The purpose is to obtain a dual-purpose folding door with excellent operability.

It is characterized by being installed .

[0007]

The female screw body 24 and the stopper claw 25 constituting the runner stopper 7 are fixed in a state of sandwiching the wall of the guide groove 11 from the inside and outside. Therefore, when the screw 26 is loosened to widen the facing distance between the female screw body 24 and the stopper claw 25, the entire runner stopper 7 can be moved along the guide groove 11 and fixed at any moving position. The runner body 13 that reciprocates along the guide rail 5 is fixed, and the runner 3 is held and fixed by engaging the stopper claw 25 with the engaging portion 23 provided on the lower end surface of the runner body 13. The runner 3 can be securely held and fixed as compared with the case where 12 is fixed. Since the stopper claw 25 and the female screw body 24 are fastened in a state of traversing the movement path of the runner 3, the overrun can be prevented even when the door 2 is vigorously closed.

[0008]

According to the folding door of the present invention, the mounting position of the runner stopper 7 with respect to the guide rail 5 can be freely changed. Therefore, the folding door can be assembled in a good appearance by changing the position where the runner 3 is held and fixed according to the variation in the shape and dimensions of the door frame. Further, the screw 26
The position can be easily adjusted only by tightening and loosening the, and the workability of the dual-purpose folding door can be improved as a whole.

With the runner body 13 as a fixing target, the stopper claw 25 fixed to the guide rail 5 and the runner body 1 are fixed.
Since the runner 3 is held and fixed by mechanically engaging with the runner 3, it is possible to prevent the runner 3 from moving when the door 2 is opened and closed, as compared with the conventional folding door in which the roller 12 is fixed.
Furthermore, since by the stopper pawl 25 and <br/> female screw member 24 which traverses the guide rail 5 can be prevented overrun runner 3, it is possible to open and close the door 2 smoothly, the combination type folding door Operability can be improved.
