DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in FIGS. 1 to 4 will be described below. First, the rotating metal fitting 7 includes the door frame 15
A pedestal 6 attached to, depending on the pedestal 6 on the shaft pin 21
And a pivoting rod 5 which is pivotally attached so as to freely pivot. In addition, the spring pin for preventing the shaft pin 21 from coming off
Wears a shear (not shown). The turning rod 5 is bent in a substantially U shape, and a hooking groove 3 is provided between the side rods 1 and 2 on both sides of the turning rod 5, and the turning rod 5 communicates with the hooking groove 3 to have a wider width. The insertion / removal groove 4 is provided on the base end side of the hooking groove 3, and on the side surfaces of the base end portions of the side rods 1 and 2 on both sides of the insertion / removal groove 4,
When the rotating rod 5 is rotated until it becomes substantially parallel to the base 6,
The tip end surface is seated on the pedestal 6 and the rotating rod 5
Is integrally provided with a protruding plate portion 10 for stopping the rotation of
On the side surface opposite to the side surface provided with the above-mentioned protruding plate portion 10 at the base end portions of the side rod portions 1 and 2 on both sides of the insertion / removal groove 4, when the rotating rod 5 is rotated in the opposite direction, Rubber-made disk-shaped cushion members 16 and 17 are directly attached to the frame 15. Next, the hook metal 9 includes a pedestal 19 attached to the door 18 and a neck portion 20 obliquely protruding from the pedestal 19.
And a substantially spherical hooking portion 8 provided at the tip of the neck portion 20. The outer diameter of the hooking portion 8 is set to be smaller than the width of the inserting / removing groove 4 of the rotating rod 5 and larger than the width of the hooking groove 3, and the outer diameter of the neck portion 20 is set to the hooking groove. It is set smaller than the width of 3.

[0006]

With the door 18 closed as shown in FIGS. 1 and 2, the rotary rod 5 is rotated in the direction of the door 18 so that the hook metal 9 is inserted into the insertion / removal groove 4 of the rotary rod 5. Insert the hook portion 8. When the door 18 is opened from this state, as shown in FIG. 3, the latching portion 8 travels and moves to the latching groove 3 and latches, so that the door 18 is not opened any more and a person enters from the outside. Can not. This kind of usage is common, but for example, in hotels
Etc., the door that was opened temporarily is closed and automatically locked.
The rotating rod 5 of the door 18 as shown in FIG.
When used outside to prevent the door 18 from closing
There is. Then, in this way, the pivot rod 5 is attached to the outside of the door 18.
Trying to close the door 18 accidentally even when it is in the open position
There is. However, even if this happens
Also, the cushion members 16 and 17 attached to the rotating rod 5 are
A shock absorber 18 is provided and is installed at the base end of the rotating rod 5.
The beam protruding plate 10 is seated on the pedestal 6 to disperse the impact.
As a result, an excessive load is applied to the pivotally connected part of the rotating rod 5.
There is no.

[0007]

[Effect of the Invention] The present invention is as described above , and is temporarily opened.
To prevent the door 18 that was open from closing and locking
The pivoting rod 5 is extended to the outside of the door 18 to prevent the door 18 from closing.
Close the door 18 when using it to stop
Even if the door 18 is abutted against the pivot rod 5 in order to
By the cushion members 16 and 17 attached to the rotating rod 5,
The shock from the door 18 is buffered, and the base end of the turning rod 5 is
By mounting the protruding plate 10 provided on the pedestal 6,
Since the strike can be dispersed, the pivoting part of the rotating rod 5
It has the effect of reducing the load on the and preventing damage. Well
In addition, the cushion members 16 and 17 attached to the rotating rod 5
Therefore, the noise generated when the door 18 collides with the rotating rod 5
It is also possible to prevent the door 18 from being damaged.
It
