Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article storage which can smoothly open and close a bellows door.

[0002]

2. Description of the Related Art Cabinets with double doors are
It is necessary to keep the retreat distance of the door when the door is opened. For this reason,
Instead of this, sliding doors and shutter-type doors are proposed, in which the doors are rolled into the cabinet storage space for storage. However, in the sliding door, it is necessary to provide a plurality of rails for sliding the plural doors in the depth direction of the storage space, and also in the shutter type door,
It is necessary to install the winding part of the door in the storage space,
The storage space becomes smaller. Therefore, in order to eliminate the door retreat distance and satisfy the demand for a large storage space, a bellows type door may be used, and each door constituent element may be configured to be foldable.

[0003]

However, in such a bellows type door, since the width of the door having the puller portion is narrow, rattling is likely to occur during sliding. For example, the upper end of the door is the lower end. There was a problem that the door could not be opened / closed smoothly because it moved ahead of the other parts.

Therefore, the present invention has been made in view of the above problems, and enables a smooth door opening / closing operation even in a bellows-shaped door that maximizes the storage space without making a retreat distance of the door. The object is to provide a storeable article storage.

[0005]

Therefore, the present invention takes the following means in order to solve the above problems. That is, in an article storage in which a door composed of a door constituent element is attached to the opening of the article storage main body, when sliding the door along the opening, the movement of a part of the door constituent element A moving mechanism for moving different portions of the door constituent elements in correspondence with the moving amount is provided. As a result, a smooth door opening / closing operation can be performed even in a bellows-shaped door that maximizes the storage space without creating a retreat distance of the door.

Further, by using the X-link mechanism as the moving mechanism, the moving mechanism can be easily constructed.

Furthermore, the weight of the components of the X-link mechanism assists the opening or closing operation of the door so that the door naturally acts in the opening or closing direction without providing a special mechanism or the like. I am trying.

Specifically, the left and right upper parts of the X-link mechanism are fixed ends for rotatably fixing along the surface of the door, and the left and right lower parts are moving ends for moving in the vertical direction. Thus, the weight of the constituent elements of the X-link mechanism causes the X-link mechanism to act in the closing direction so that the door 2 can always be naturally opened.

Further, the left and right lower portions of the X-link mechanism are fixed ends for rotatably fixing along the surface of the door, and the left and right upper portions are movable end portions for moving in the vertical direction. The weight of the constituent elements of the X-link mechanism causes the X-link mechanism to spread in the direction of opening so that the door 2 can always be naturally closed.

In addition, by providing a projecting portion that can move forward and backward at a position that obstructs the movement path of the moving end portion provided in the X-link mechanism, the X-link mechanism can be fixed in an open state and easily described above. The door can be locked.

Further, the door is constructed by connecting a plurality of door constituent elements in a corrugated plate shape so that the initial folding operation of the door can be smoothly started.
