Openable apparatus and permutation lock unit

Abstract

Provided is an openable apparatus configured such that an engaging member such as a locking hook is effectively prevented from accidentally bumping against a housing during handling of an opening member. The openable apparatus is provided with a housing (1), a door (2) which is an opening member for opening or closing an opening on the housing (1), an actuating member (31) and an engaging member (33) which are provided on the door (2), and a keeper member (11) which is provided on the housing (1), said openable apparatus keeping the door (2) in the closed position by engaging the engaging member (33) with the keeper member (11). The actuating member (31), which serves additionally as a knob for opening and closing the door (2), moves from the closing position (P1) upon receipt of an unlocking action, and reaches the opening position (P2) while accumulating an actuating force for returning to the closing position (P1) during the movement from the closing position (P1) to the opening position (P2). The engaging member (33) is provided with a working area where the engaging member (33) interlocks with the actuating member (31) and a working area where the engaging member (33) does not interlock with the actuating member (31). While the actuating member (31) is moving from the closing position (P1) to the opening position (P2), the engaging member (33) is interlocked so as to move from the locked position (Q1) to a middle position (Q3), and at this time cannot pass an aperture edge (1a) on the housing (1). Subsequently, when the actuating member (31) has reached the opening position (P2), the engaging member (33) moves further, from the middle position (Q3) to the unlocked position (Q2) where the engaging member (33) can pass the aperture edge (1a) on the housing (1). Then, when the actuating member (31) as the knob has opened the door (2) in this state, the actuating member (31) is restrained by a restraining means (E).

Description

technical field [0001] The present invention relates to an opening and closing device that effectively prevents an engaging portion such as a lock hook from colliding violently with a case when opening and closing an opening and closing member. Moreover, this invention relates to the dial lock unit which can be easily attached to the door of a box, etc., can reduce the necessity of the process of a box side, and is excellent in usability. Background technique [0002] Conventional opening and closing devices that use dial locks are usually attached to doors and the like that have engaging parts such as latches, and are configured to restrain the card by disabling the operation of the operating part by setting the dial lock to a non-coded state. When the door is opened, the dial lock can be coded so that the operation of the operating part can be performed, and when the door is closed, the dial lock is reset to a non-coded state again. [0003] In addition, it is preferable ...

AI Technical Summary

Problems solved by technology

[0008] However, when the above configuration is adopted, a large amount of processing and / or additional functions need to be performed on the cabinet including the door, resulting in an increase in cost

In addition, after the door is closed, the lock cannot be locked without operating the operation part, so the closing procedure is complicated and inconvenient to use

In addition, the coded state of the dial continues until the door is closed, so it is not ideal in terms of safety.
