Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixed stay device capable of fixedly holding a wing body such as a door or a lid to a fixed frame body such as a building body or a box body in a predetermined opened state.

[0002]

[Prior Art]

 A guide hole is pierced through the side wall of the support cylinder in the diametrical direction, an arm is slidably fitted in the guide hole, and a bracket is pivotally connected to the tip end of the arm, and is attached to the base end of the support cylinder. A fixed stay device in which a bracket is connected by a pivot, a screw rod of a tightening board is screwed into a central screw hole of a cap fixed to the tip of a support cylinder, and the tip end face of the screw rod is abutted against the front ventral face of the arm. Is already known.

In this fixed type stay device, when the wing body is opened and rotated, the support cylinder and the arm rotate about the respective pivots, while the arm moves in the transverse direction of the support cylinder. The wing is fixed and held in the open position by tightening the tightening board.

However, in this fixed stay device, the abutting position of the screw rod of the tightening board can be arbitrarily selected along the length direction of the arm, so that the wing body is fixed and held at an arbitrary opening angle. Although it is possible, the tightening board has to be rotated many times to open and close the wing body, so the operation is not quick. Also, when the screw rod is loosely tightened due to an operation error, the wing body may unintentionally close due to wind pressure.

[Problems to be solved by the device]

 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fixed stay device which can easily and quickly perform the operation of fixing and holding the wing body and can accurately and hold the wing body at a predetermined position without any room for an operation error. ..

[0006]

[Means for achieving the object]

 Hereinafter, referring to the reference numerals in the accompanying drawings, in the fixed stay device of the present invention, guide holes 7 and 8 are provided in the side wall portion 12 of the support tube 2 so as to penetrate in a radial direction. The arm 1 is slidably fitted into the arm 8, the first bracket 3 is connected to the tip of the arm 1 by the pivot 4, and the bottom board 13 and the mounting board are fitted and fixed to the rear end of the support tube 2 by stacking. , The second bracket 5 is connected to the mounting plate 26 by the pivot 6, the lock plate 9 is fitted into the support cylinder 2 on the rear side of the arm 1, and the lock plate is inserted by the compression coil spring 10 housed between the bottom plate 13 and the lock plate 9. The rear side abdominal surface 11 of the arm 1 is provided with a locking recess 15 into which the stop projection 14 of the front surface 19 of the lock board 9 engages and disengages.

The operation button 20 is fitted into the through hole 24 of the front wall portion 23 of the support cylinder 2, and the pedestal 18 on the rear surface side of the operation button 20 is provided with leg portions 21 and 22 straddling the arm 1. The rear ends of the parts 21, 22 are brought into contact with the front surface 19 of the lock board 9, and the operation button 20 is slidably biased forward by the compression coil spring 25 housed between the pedestal body 18 and the arm 1. 25 is supported between the legs 21 and 22.

In another embodiment, in the fixed stay device described above, a plurality of locking recesses 15 are provided along the length direction of the arm 1.

[0009]

[Action]

 In one usage mode of this fixed stay device, the first bracket 3 is fixed to the wing body 16 and the second bracket 5 is fixed to the fixed frame body 17. When the wing body 16 is opened and rotated about a hinge shaft (not shown), the arm 1 rotates about the pivot shaft 4 with respect to the wing body 16, while the support cylinder 2 rotates around the pivot shaft 6 as a fixed frame body. It rotates with respect to 17, and the arm 1 moves in the transverse direction of the support tube 2.

During this rotation operation, the upper end surface of the stop projection 14 of the lock board 9 is in sliding contact with the belly surface 11 of the arm 1. When the wing body 16 rotates to a predetermined angle, the stop projection 14 of the lock board 9 automatically engages with the lock recess 15 of the arm 1 by the bias of the compression coil spring 10, and the engagement is accurately maintained. .. Therefore, the wing body 16 is fixedly held in a predetermined open position.

To close the wing body 16, the front end portion of the operation button 20 is pushed into the through hole 24 against the bias of the compression coil spring 25, and the lock board 9 is moved to the leg portions 21, 2, 2 of the pedestal body 18. The stop projection 14 of the lock board 9 is disengaged from the lock recess 15 of the arm 1 by pushing down with. After that, when the wing body 16 is closed and rotated about the hinge axis, the arm 1 rotates about the pivot axis 4 with respect to the wing body 16 as described above, while the support tube 2 rotates about the pivot axis 6. Then, the arm 1 rotates relative to the fixed frame body 17, and the arm 1 moves in the transverse direction of the support cylinder 2.

When the wing body 16 is slightly rotated and the stop projection 14 of the lock board 9 moves to a position where it does not face the locking recess 15 of the arm 1, the finger is released from the operation button 20, and the operation button 20 is released. The front end of the compression coil spring 25 is returned to the standby position protruding from the through hole 24 by the biasing force of the compression coil spring 25. During the subsequent rotation operation, the stop projection 14 of the lock board 9 makes sliding contact with the abdominal surface 11 of the arm 1 and the wing body 16 is fully closed.

When the arm 1 is provided with a plurality of locking recesses 15, the wing body 16 has a release angle by appropriately selecting the locking recesses 15 with which the stop projections 14 of the lock board 9 engage. It is fixedly held in a plurality of different open positions.
