Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a temporary locking device mainly for hanging doors or folding doors that is easy to assemble.

(Prior art and its problems) There have been many ideas regarding this type of temporary locking device, but in all of them, when the handle is pulled in the direction of opening the door, the sickle-shaped locking rod rotates and is released from the locking device. Since it was a lock that could be unlocked from a distance, the lock case could only be installed in a position related to the handle, which was a drawback, and the assembly work was also done from the side of the lock case. However, various work steps are required, such as screwing the rear side plate to which the locking rod and other movable members are attached, and the manufacturing cost is high.

(Purpose of the device) In order to solve the above-mentioned problems, the purpose of this device is to provide a temporary locking device that can be easily assembled by simply pushing the necessary parts into the front opening of a casing that is integrally molded from synthetic resin or the like, and then inserting a pivot pin from outside the casing and crimping it, and which does not need to be attached in a position relative to the handle.

(Disclosure of the invention) The specific structure of the invention includes a locking member 1 in which a hook portion 1 ₂ is integrally protruded from a flat board 1 ₁ , the front surface is open, and the rear corner portion 2 ₁ is shaped like an arc. In the vicinity of the opening in the formed casing 2, a roughly triangular temporary locking member 3 is provided, which has a locking portion ₃₂ that engages with an arcuate recess ₃₁ and a hook portion ₁₂ of the locking member 1. A cylindrical body 5 is rotatably supported on a shaft 4 and has a hemispherical head ₅₁ at the end thereof, and a hemispherical head is attached to the tip of a shaft part ₆₁ that is slidably inserted into the cylindrical body. A pusher 8 consisting of a piston 6 provided with a portion 6 ₂ and a spring 7 interposed between the heads 5 ₁ , 6 ₂ is connected to its heads 5 1 , 6 ₂ .
6 ₂ is composed of a locking device 9 configured by fitting into the corner portion 2 ₁ of the casing 2 and the recess 3 ₁ of the temporary locking member 3, respectively, and the locking member 1 is configured to fit into the corner portion 2 1 of the casing 2 and the recess 3 ₁ of the temporary locking member 3.
is attached to the end face of the door with screws, and the locking device 9 is mounted on the vertical stile of the door frame at a position facing the hook portion ₁₂ of the locking member 1. In the case of this embodiment, the casing 2
One side plate of the casing 2 is extended vertically to form a flange for surface mounting, but if a front plate-like flange is formed on the front opening side of the casing 2 instead of this flange, it becomes a recessed type. be able to.

(Operations and Effects of the Invention) According to the above-mentioned configuration of the invention, the operations and effects of the apparatus of the present invention will be explained with respect to the illustrated embodiments.

That is, in FIG. 1, in the locking device 9, the pusher 8 interposed between the corner ₂₁ of the casing 2 and the recess ₃₁ of the temporary locking member 3 is temporarily held by the restoring force of the spring 7. This shows the state in which the locking member 3 is pushed so as to rotate and protrude clockwise about the shaft 4, and the temporary locking member partially engages with the stepped portion provided at the bottom of the casing 2, preventing further locking. Rotation is regulated.

When the door is closed in this state, the hook portion 12 of the locking member ₁ attached to the end face of the door enters the inside of the casing from the front opening of the casing 2, and at the same time,
Since the base plate ₁₁ presses the protruding portion of the temporary locking member 3 and pushes the temporary locking member 3 counterclockwise against the pressing force of the pusher 8, the pusher 8
is tilted by the sliding action of the hemispherical heads 5 ₁ and 6 ₂ at both ends, and when it reaches the position shown in FIG. 5, it presses the temporary locking member 3 so as to rotate it counterclockwise. In other words, in this state, the locking member 1
The hook portion 1 ₂ engages with the locking portion 3 ₂ of the temporary locking member 3,
Since the temporary locking member is in a state where resistance is applied to the clockwise rotation due to the pressing force of the pusher 8, the door cannot be opened even if the door is pulled with a slight force, resulting in a so-called temporary locking state. It's summery.

When the door is pulled against the resistance, the temporary locking member 3 is rotated as shown in FIG. 1 by the force applied by the hook ₁₂ of the locking member 1. The hook portion ₁₂ is disengaged from the locking portion ₃₂ , and the door is opened.

Thereafter, the above operation is repeated every time the door is opened or closed.

As described above, according to the temporary locking device of the present invention, the temporary locking member that acts as a sickle-shaped locking rod is operated by a click motion, and the resistance during this operation is used to perform the temporary locking action. Because of this, there is no need to attach it to a position related to the handle as in conventional devices, and it is convenient because it can be attached to the upper or lower part of the door. Because it uses pushers that do not require branches,
With one head of the pusher fitted into the recess of the temporary locking member, insert it through the opening at the front of the casing, and connect the pivot holes previously drilled in both sides of the casing to the pivot holes for the temporary locking member. It can be easily assembled by aligning the holes in the shaft, inserting the shaft, and caulking both ends of the shaft outside the casing.The locking member can also be integrally molded from synthetic resin, making it inexpensive to manufacture. It has a great effect.
