Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for preventing a panel drop accident due to breakage of left and right (movable) tabs provided on a hanging fitting when a panel or the like is hoisted.

[0002]

2. Description of the Related Art In a conventional panel lifting metal fitting,
Basically, it is used for a single-sided panel, and when the panel is hoisted during the installation work, it is basically manually attached and removed from the inside. However,
Recently, there are many cases where installation work using double-sided panels,
At that time, it takes a lot of time and labor to attach and detach the metal fittings after hollowing out and removing a part of the inner wall.

The panel hanging metal fitting of Japanese Unexamined Patent Publication No. 8-20488, which was developed to solve the above-mentioned problem, is provided with tabs on the left and right for hooking the panel on the main body, and the shaft can be pressed by pressing the handle. As soon as it is pushed into the pipe, the left and right claws are stored in the main body through the storage holes provided in the pipe of the main body, and when the handle is released, the force of the spring provided between the grip and the handle expands. ， At the same time when the shaft is pulled out from the main body, the extending force of the springs provided on the left and right pawls and the shaft is transmitted, and each pawl comes out of the main body. Attaching and detaching the metal fitting to the panel The method of easily performing is mentioned.

In the case of the method by the above means, in order to solve the problem in the durability of the springs provided on the left and right claws and the shaft respectively, Japanese Patent Application No. 7-127007
By fixing the pin near the claw accommodating hole of the pipe and attaching the groove for sliding the pin on the shaft, the panel suspension metal fitting of No need to use the spring. It is said that the structure can be smoothly operated due to the elimination of the gap, and at the same time, the cross-sectional area is increased, the strength is increased, and the structure and the assembly are simplified.

[0005]

However, in the case of the method according to the above means, when the panel or the like is hung, even if the movable left and right claws that secure the strength are used, they are damaged. In this case, since there is no safety device, there is a drawback that it could lead to accidents such as dropping of panels.

The present invention provides a highly safe panel hanging metal fitting by providing a safety device for preventing a fall accident due to breakage of the movable left and right claws which is the above-mentioned problem. It is an object.

[0007]

[Means for Solving the Problems] In order to achieve the above object,
In the panel hanging metal fitting of the present invention, as a safety device,
Attach the front and back claws fixed to the grip side of the pipe so that they cross the right and left (movable) claws provided on the hanging bracket body at a right angle.

At this time, since the front and rear claws, which are safety devices, must be inserted into the main body of the panel or the like, the structure of the holes provided in the ordinary panel or the like becomes complicated. In order to solve the problem, a new receiving metal fitting is installed to receive the hanging metal fitting. At that time, after mounting the receiving bracket to the panel body, when actually using it, insert the hanging bracket into the receiving bracket already attached to the panel body, and then lift it with a crane or the like.

The structure of the receiving metal is mainly composed of two pipes and two pipes.
It is composed of a number of metal plates. If explained in order from the top, it is composed of a metal plate, a pipe, a metal plate, and a pipe (with a lid). On the upper metal plate, attach the holes for the suspension metal fittings and front and rear tabs (fixed type). The lower metal plate is provided with holes for inserting only the main body with the left and right (movable) claws closed, and the respective metal plates and pipes are welded. For pipes mounted below the lower metal plate, thin sheet material may be used.

[0010]

[Operation] When inserting the panel hanging metal fitting configured as described above into the receiving metal fitting already attached to the panel body,
Push in the handle in advance and store the left and right (movable) tabs. Then, after inserting the main body into the receiving metal fitting, after inserting the left and right (movable) hooks at right angles, into the insertion holes provided in the upper metal plate of the front and rear (fixed type) hooks ， Release the handle. Or, in the case of a suspension fitting with a lock mechanism, when the lock is released,
Left and right (movable) claws come out and it is possible to lift. When the wire is actually lifted, the rotating force is transmitted to the shackle by pulling the wire, and at the same time, the hanging metal fitting itself changes its direction. Therefore, the front and rear (fixed) claws are inserted into the claws provided on the upper metal plate. Even if the left and right (movable) claws are damaged, the front and rear (fixed) claws will be lifted, so that they almost intersect the mouth.
It is possible to prevent a fall accident due to damage to the left and right (movable) claws.
