[Detailed Description of the Invention] The present invention relates to an opening/closing device for a glass door of an audio rack and other doors.

The glass door and other doors of the audio rack have two or one door pivoted at one end in the vertical direction to the box body, and are opened horizontally toward the front.

Therefore, it is necessary to secure a space corresponding to the width of the door in front of the box body, etc., and the open door tends to get in the way.

Therefore, for example, Japanese Patent Publication No. 11177-1977 discloses a door that is divided into two parts to shorten the length of the door protruding from the box when opened. Sometimes it is necessary to pull it by hand.

Moreover, since it is necessary to provide a knob on the door, if the door is made of glass, a lot of effort is required to attach the knob, and there is also the problem that it looks unsightly.

This proposal shortens the length that the door protrudes from the box body when the door is opened, and also simplifies the operation of opening the door.
The purpose is to improve the appearance of the door.

The proposed device divides the door into a plurality of pieces, connects them to each other with spring hinges, and pivots one end of the door to the box body.

Hooks that engage with each other are attached to the door side and the box body, and the hooks on the box body can slide in the direction opposite to the hooks on the door side, and the hooks on the box body can slide in the direction opposite to the hooks on the door side. One end is attached to a hook attached to the box body, and the other end of the swing arm, whose middle part is pivoted to the box body, is attached to the outside of the box body in the opposite direction to the direction in which the hook is biased by the spring. The protruding release body is attached, and the supporting shafts protruding above and below the end opposite to the pivoting part of the door are inserted into the rails provided along the edges of the top plate and bottom plate of the box body. It is characterized by

When opening the door using this opening/closing device, the opening member is pushed and the swing arm swings, thereby moving the hook on the box body and separating it from the hook on the door side.

Then, the spring hinge that connects the door folds the door using its spring force, and the pivot moves along the rail, allowing the door to open at the same time as it folds.

When closing the door, the door is kept in a closed state by separating the folded door into a straight line and engaging the pair of hooks with each other.
