Description

[Detailed description of the invention] Conventionally, as a guard fitting for outward-swinging doors and inward-swinging doors, a rotating fitting 5 is provided on one side of the door or door frame, and a latch fitting 7 is provided on the other side. There is a door that is movably latched to the latch fitting 7 by rotation of the door, so that the door can be opened by a certain width.

However, with this type of safety bracket, when the door is suddenly closed due to wind, etc., the rotating bracket may inadvertently rotate due to the impact and lock with the latch bracket, causing the door to close indoors. There was a risk that there would be many cases where it would not be possible to enter.

There is a particular risk of this occurring with doors that swing outward, and each time you enter the building from a place other than the entrance door, or if other windows are locked, or if you live in a high-rise building, you may enter the building. This is often extremely difficult.

This project was researched to eliminate these drawbacks of conventional safety fittings, and succeeded in eliminating the above-mentioned drawbacks by locking the rotating fitting with one touch so that it does not rotate when not in use. .

To describe the present invention in detail with reference to the illustrated embodiment, a U-shaped rotating rod 3 having a wide insertion hole 1 at the base end and a running groove 2 communicating with the insertion hole 1 is mounted on a pedestal 4 and can be rotated left and right. A rotating metal fitting 5 pivotally attached to the rotating rod 3, and a hooking portion that can be freely inserted and removed only into the insertion hole 1 of the rotating rod 3 and is large enough to be hooked on the running groove 2. 6, a rotating plate 10 which can be rotated rearward is pivotally attached to a separate mounting base 9 by a pin shaft 11, and the upper front surface of the rotating plate 10 is A hook 12 is provided, and the lower surface of the hook 12 is connected to the rotating rod 3 of the rotating fitting 5.
A locking recess 13 into which the tip of the hook 12 locks, and a pressing sliding portion 14 which slopes the upper surface of the hook 12 downward.
and the lower position 1 of the rotating plate 10 than the pin shaft 11
0' is provided with a spring hooking recess 15 and the mounting pedestal 9 is
One end of a pressing spring 16 attached to the lower cavity 9' is hooked and presses the rotary plate 10 rearward. Note that a coil spring may be used as the spring 16.
Also, other springs may be used.

In the figure, 17 is a knob that projects above the hook 12, and 18 is an obstruction protrusion that abuts against the mounting base 9 to prevent the rotating plate 10 from tilting forward.

The present invention is realized as described above, and in order to use this, as shown in FIG. The mounting base 9 is fixed so that the mounting plate 9 corresponds to the mounting plate 9, and when the guard is not used, the rotating rod 3 is rotated and pressed, so that the rotating rod 3 slides down the pressing sliding part 14 of the hook 12 and the rotating plate The entire rotating plate 10 rotates backward against the spring 16, and the tip of the rotating rod 3 is engaged with the latching recess 15, so that the rotating plate 10 is restored to the front position. To release the lock between the rotating rod 3 and the latching recess 15, it is sufficient to hold the knob 17, tilt the rotating plate 10 backward, and lift the rotating rod 3.

As mentioned above, when the safety fitting is not used, the rotating rod can be engaged in the latching recess by the simple action of pressing the rotating rod against the pressing and sliding part of the hook, thereby preventing the rotating rod from being accidentally rotated. Even if the door is latched and the door is forcefully closed by wind or the like, the rotating rod and the hook will not come off, and therefore will not be locked with the latch.

Claims (1)

[Scope of utility model registration request] A rotating metal fitting in which a rotating rod having a wide insertion hole at the base end and a running groove communicating with the insertion hole is pivoted to a pedestal so as to be able to freely rotate from side to side, and only the insertion hole of the rotating rod. In the case of a safety fitting consisting of a latching fitting that can be inserted freely and has a latching part large enough to be latched onto the running groove, a rotating plate that can be rotated rearward is separately attached to the top of the mounting base. A hook is provided on the front surface of the moving plate, and the lower surface of the hook is a latching recess into which the tip of the rotating rod of the rotating metal fitting is hooked, and the upper surface of the hook is a downwardly sloping pressing sliding part, so that the rotating plate is provided with a hook. is a stopper for a door guard that is pressed forward and rotated using a spring.
