DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening angle adjusting device for freely adjusting an opening angle of a door provided rotatably around a vertical axis.

[0002]

2. Description of the Related Art Conventionally, a door provided at a building entrance or the like so as to be rotatable around a vertical axis is a double door between a building upper frame and a door so that the maximum opening angle is a predetermined angle. Arm is provided. When such a double arm is provided between the building-side upper frame and the door, the maximum opening angle of the door is determined by the mounting position of the arm with respect to the building-side upper frame and the door. There is a problem that the position where the arm mounting hole is formed at the time of manufacturing is very severe, and if the position of the arm mounting hole is slightly displaced, the maximum opening angle of the door changes.

[0003]

SUMMARY OF THE INVENTION The present invention solves such a problem, and a door opening angle adjusting device for freely adjusting the opening angle of the door even when the mounting position of the upper frame on the building side and the door is changed. The purpose is to provide.

[0004]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention relates to a door opening angle adjusting device provided to be rotatable about a vertical axis, and attached to a building-side upper frame or door. A wire stopper, a plate attached to the door or the building upper frame, and a wire connecting the wire stopper and the plate, wherein the wire stopper is a wire stopper body attached to the building upper frame or the door. Holding means for gripping a wire inserted into the wire stopper body, the holding means having a plurality of ball-shaped holding members attached to a freely openable and closable support member in the wire stopper body, and one end of the support member The wire drawn from the wire is guided to the plate side, and the ball-shaped holding member is When the wire passing through the plurality of ball-shaped holding members is pulled toward the small diameter side of the tapered surface in a state in which the ball-shaped holding member is in contact with the tapered surface on the inner surface of the stopper body, the ball-shaped holding member is in the same direction as the wire due to friction with the wire. The ball-shaped holding member is configured to hold the wire and stop the movement of the wire from one end of the wire stopper main body facing the small diameter side of the tapered surface, and one end of the wire stopper main body. One end of the support member protrudes from the wire stopper main body due to the urging force of a spring provided in the wire stopper main body, and one end side of the support member protruding from one end of the wire stopper main body is opposed to the spring force inside the wire stopper main body. The ball-shaped holding member moves toward the large-diameter side of the tapered surface by pushing It is intended to be subject matter of which is configured to release the holding of yer.

[0005] With this configuration, it is possible to provide a door opening angle adjusting device that freely adjusts the opening angle of the door even when the mounting position with respect to the building upper frame and the door changes. Further, even if a slight error occurs in the mounting position of the wire stopper to the upper frame on the building side and the mounting position of the plate to the door, there is no problem, and the opening angle of the door can be freely adjusted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 to 3,
A door 1 is provided at the entrance 2 of the building so as to be rotatable around a vertical axis. A wire 4 is provided between the door 1 and the upper frame 3 on the building side.
An opening angle adjusting device 5 for the door 1 is provided.

The opening angle adjusting device 5 includes a wire stopper 6 attached to the upper frame 3 on the building side, and a plate 7 attached to the upper end of the door 1 to hold one end of the wire 4 and to support the wire stopper 6. In the above, the wire 4 stops in the door opening direction. More specifically, the wire stopper 6 is composed of a bracket 9 attached to the building-side upper frame 3 with screws 8 and a bent piece 1 at both ends of the bracket 9.
The wire stopper main body 12 is screwed into the screw hole 10a of one of the bent pieces 10 far from the door 1 to be opened, and is inserted into the wire stopper main body 12. Holding means 13 for gripping the wire 4. The holding means 13 is a support member 14 which can be opened and closed in the wire stopper main body 12.
A plurality of ball-shaped holding members 15 are attached to the wire stopper body 15 and the wire 4 passing through the plurality of ball-shaped holding members 15 is tapered so that the ball-shaped holding members 15 are in contact with the tapered surface 16 on the inner surface of the wire stopper body 12. By being pulled toward the small diameter side of the surface 16 (one end side of the wire stopper body 12), the ball-shaped holding member 15 is pulled in the same direction as the wire 4 by friction with the wire 4,
The ball-shaped holding member 15 is configured to strongly hold the wire 4 and stop the movement of the wire 4 from one end of the wire stopper main body 12. One end of the support member 14 protrudes from one end of the wire stopper main body 12 by the urging force of a spring 17 provided in the wire stopper main body 12, and the length of the wire 4 between the wire stopper 6 and the plate 7 is increased. When it is desired to increase the length, the one end of the support member 14 protruding from one end of the wire stopper main body 12 is pushed into the wire stopper main body 12 against the force of the spring 17 so that the ball-shaped holding member 15 is tapered. The wire 4 can be pulled out from one end of the wire stopper main body 12 by moving to the large diameter side of the surface 16 to release the pinching of the wire 4. When the length of the wire 4 is to be reduced, the wire 4 protruding from the other end of the wire stopper main body 12 is used.
By pulling the other end of the wire 4, the wire 4 can be moved within the support member 14 without receiving a strong holding force by the ball-shaped holding member 15, and the length of the wire 4 can be shortened.

A guide hole 18 is formed in one of the bent pieces 10 and 11 at both ends of the bracket 9 so as to insert one end of the wire 4 projecting from one end of the wire stopper body 12. ing. One end of the wire 4 is inserted into a hole 7a formed in the plate 7, and a ball-shaped retaining member 19 having a larger diameter than the hole 7a is attached and supported.

As described above, the opening angle adjusting device 5 having the above structure is provided between the upper frame 3 on the building side and the door 1, and the wire 4 between the wire stopper 6 and the plate 7 according to the opening angle of the door 1. , The door 1 can always be opened at the same opening angle. In particular, the upper frame 3 on the building side
Even if there is some error in the mounting position of the wire stopper 6 with respect to the door 1 and the mounting position of the plate 7 with respect to the door 1, the length of the wire 4 between the wire stopper 6 and the plate 7 can be freely adjusted to make the door 1 Can be obtained.

In the embodiment described above, the wire stopper 6 is attached to the upper frame 3 on the building side, and the plate 7 is attached to the door 1. However, the plate 7 is attached to the upper frame 3 on the building side, and the wire stopper 6 is attached to the door 1. You may make it attach.

[0011]

As described above, according to the present invention, it is possible to provide a door opening angle adjusting device which can freely adjust the opening angle of the door even when the mounting position with respect to the building upper frame and the door is changed. Further, even if a slight error occurs in the mounting position of the wire stopper to the upper frame on the building side and the mounting position of the plate to the door, there is no problem, and the opening angle of the door can be freely adjusted.
