Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed stay which can hold and hold 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 open state.

[0002]

2. Description of the Related Art A guide hole is formed through a side wall of a support cylinder in a diameter direction, an arm is slidably fitted in the guide hole, and a bracket is pivotally connected to a tip end of the arm to support the base of the support cylinder. The bracket was pivotally connected to the end, and the screw rod of the tightening board was screwed into the central screw hole of the cap fixed to the tip of the support cylinder, and the tip end face of the screw rod was abutted against the front ventral face of the arm. Fixed stays are already known. In this fixed stay, 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 fixedly held in the open position by operation.

However, in this fixed type stay, since the abutting position of the screw rod of the tightening board can be arbitrarily selected along the length direction of the arm, the wing body can be fixed and held at an arbitrary opening angle. However, since the tightening board has to be rotated many times to open and close the wing body, the operation speed is lacking. Further, when the screw rod is loosely tightened due to an operation error, the wing body may unintentionally close due to wind pressure.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to fix and hold a wing body easily and quickly, and to fix the wing body exactly at a predetermined position without any room for operation error. It is to provide a mold stay.

[0005]

The fixed type stay of the present invention will be described below with reference to the reference numerals in the accompanying drawings.
Guide holes 7 and 8 are provided through the side wall portion 12 of the support cylinder 2 in the diametrical direction, the arm 1 is slidably fitted in the guide holes 7 and 8, and the first bracket 3 is attached to the tip end portion of the arm 1 by the pivot 4
The second bracket 5 is connected to the base end of the support cylinder 2 by the pivot 6, and the lock plate 9 is slidably fitted into the support cylinder 2 at the rear side of the arm 1.

A compression coil spring 10 housed between the bottom wall portion 13 of the support tube 2 and the lock plate 9 biases the lock plate 9 to slide forward, and a stop projection 1 is formed on the front surface 19 of the lock plate 9.
4 is provided with a lock recess 15 for engaging and disengaging the stop projection 14 on the rear abdominal surface 11 of the arm 1, and the operation button 20 is fitted to the support cylinder 2 on the front side of the arm 1 and extends over the arm 1. The leg portions 21 and 22 of 20 are brought into contact with the front surface 19 of the lock board 9, and the pressing portion 2 of the operation button 20 is inserted from the through hole 24 of the cap 23 fixed to the tip of the support cylinder 2.
5 is projected.

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

[0008]

In one mode of use of this fixed stay, 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 the hinge axis 18, the arm 1 rotates about the pivot axis 4 with respect to the wing body 16, while the support cylinder 2 rotates about the pivot axis 6 with respect to the fixed frame body 17. Then, the arm 1 moves in the transverse direction of the support tube 2.

During this rotation operation, the stop projection 1 of the lock board 9
The upper end surface of 4 is in sliding contact with the belly surface 11 of the arm 1. When the wing body 16 rotates to a predetermined angle, the compression coil spring 1
With the bias of 0, the stop projection 14 of the lock board 9 is moved to the arm 1
The lock recess 15 is automatically engaged, and the engagement is accurately maintained. Therefore, the wing body 16 is fixedly held at a predetermined open position.

To close the wing body 16, the pressing portion 25 of the operation button 20 is pushed and the lock board 9 is operated by the operation button 2.
The stop projection 14 of the lock board 9 is disengaged from the locking recess 15 of the arm 1 by pushing down with the 0 legs 21 and 22. After that, when the wing body 16 is closed and rotated about the hinge shaft 18, the arm 1 rotates about the pivot shaft 4 with respect to the wing body 16 as described above, while the support cylinder 2 is fixed about the pivot shaft 6. The arm 1 rotates with respect to the frame body 17, and the arm 1 moves in the transverse direction of the support cylinder 2.

When the wing body 16 slightly rotates and the stop projection 14 of the lock board 9 moves to a position where it does not face the lock recess 15 of the arm 1, the pressing portion 2 of the operation button 20 is pressed.
The finger is released from 5. During the subsequent rotation operation, the stop projection 14 of the lock board 9 slides on the belly 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 can be obtained by appropriately selecting the locking recesses 15 with which the stop projections 14 of the lock board 9 engage.
Is fixedly held in a plurality of open positions having different open angles.

[0013]

In the illustrated embodiment, the arm 1 is composed of a thick-walled flat bar, and two locking recesses 15 are provided. The base end of the support tube 2 is pivotally attached to the second bracket 5 via a packing 26. The cap 23 is screwed onto the upper end of the support tube 2. Compression coil spring 1
0 is made of bamboo spring.

A retaining protrusion 27 is provided at the base end of the arm 1, and the retaining protrusion 27 contacts the side wall portion 12 of the support barrel 2 to prevent the arm 1 from being pulled out from the support barrel 2. .

[0015]

As described above, in the fixed stay of the present invention, the lock plate 9 is supported by the support cylinder 2 on the rear side of the arm 1.
The lock disc 9 is slidably biased forward by the compression coil spring 10, and the lock projection 15 provided on the front surface 19 of the lock disc 9 is engaged with and disengaged from the lock concave portion 15 on the rear abdominal surface 11 of the arm 1. The operation button 20 is fitted into the support cylinder 2 on the front side of the arm 1, and the legs 21 and 22 of the operation button 20 straddling the arm 1 are brought into contact with the front surface 19 of the lock board 9 and fixed to the tip of the support cylinder 2. Since the pressing portion 25 of the operation button 20 is projected from the through hole 24 of the cap 23, the arm 1 can be locked and released with respect to the support cylinder 2 only by pressing the operation button 20.
The operation of fixing and holding the wing body 16 can be performed quickly and accurately without fear of an operation error.

In the fixed stay according to the second aspect, since the arm 1 is provided with the plurality of locking recesses 15 along the length direction, the wing body 16 is fixedly held at a plurality of positions having different opening angles. be able to.
