Description

[Detailed description of the invention] (1) Technical field of the invention The invention provides a hook having a latch located on the mating side of the door and a C-shaped locking groove located above or below the latch, or on either side of the latch. This invention relates to a hook receiver used in a locking device consisting of.

(2) Prior art and its problems Conventionally, since the vertical width of the door is relatively large, in the case of doors such as lockers, the latch is placed in the center of the door, and the latch is placed in the upper and lower ends of the door. A locking device consisting of a pair of hooks is used. However, when closing the door, this locking device maintains the latch and hook in the unlocked state by operating the operating knob, etc., and then moves the latch toward the main body by returning the operating knob, etc. The door must be fitted into a drilled mounting groove and the hook must be engaged with a locking member that stands stationary on the main body, making closing the door cumbersome.

For this reason, the applicant proposed that when the door is closed, the latch comes into contact with the main body and is ejected into the lock main body, and when the latch leaves, the hook is rotated in the unlocking direction, and the latch is attached. A locking device in which the above-mentioned latch and the hook are interlocked is proposed so that the hook is rotated in the locking direction at the same time as the hook is inserted into the groove.
It was proposed in No. 57-71861 (Utility Model Publication No. 58-174579).
However, with this structure, the outer surface of the hook protrudes toward the locking member rather than the working surface that guides the withdrawal of the latch. Therefore, when the door is closed, the outer surface of the hook may come into contact with the locking member during rotation, and the subsequent rotation may be restricted by the locking member. Even in this state, the operation from the start of closing to the locking of the door is continuous and instantaneous, and the hook is forcibly rotated in the opposite direction while causing twisting in the connecting portion between the latch and the hook. It has been pointed out that this causes a misalignment of the locking member and the hook, making it difficult to close the door. To solve this problem, it is possible to make the latch's working surface protrude so as to reduce the difference in protrusion between the latch's working surface and the outside surface of the hook. This is not allowed due to the structure of the storage section of the main body that is constructed around the mounting groove.

(3) Purpose of the invention The purpose of the invention is to provide a hook holder that can maintain the alignment of the hook and the locking member without changing the structure of the main body or the locking device, in view of the conventional situation described above. .

(4) Structure of the invention In order to achieve the above purpose, the structure of the invention is as follows:
A hook receiving main body attached to the main body side, a locking member protruding from the hook passing surface of the hook receiving main body in an elastic state so as to be freely protrusive and retractable, and a locking member provided on the upper surface of the locking member that is attached to the outer surface of the hook when the door is closed. The door stopper is characterized by comprising an upwardly inclined guide surface which causes the locking member to retreat in accordance with the rocking movement of the locking member, and a door stop that is adjustable and protrudes from the front surface of the hook receiver main body.

(5) One Embodiment of the Invention Hereinafter, an embodiment of the hook receiver according to the present invention will be explained in detail with reference to FIGS. 1 to 4.
