Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf unit for assembling an upright member serving as a pillar by assembling it to a shelf or a chest.

[0002]

2. Description of the Related Art A shelf unit is one in which the mounting position of a shelf or chest can be freely selected and changed. For example, a shelf unit can be combined with an upright to assemble a bookshelf, a display shelf, or a room space. There is one that is assembled by appropriately combining a shelf and a chest according to the application.

A shelf is a shelf board on which various kinds of articles are placed, and in addition to the original shelf board, there are a desk top board on which a personal computer display, a keyboard, etc. are placed, and a table top board. The chest has a box-like shape for accommodating various items, and examples thereof include a swing door type or drawer type cabinet, a magazine rack, and the like.

Most conventional shelf units are assembled by assembling two upright members at the left and right ends of the shelf or chest, respectively, and the connecting portion is the end face of the shelf 60 as shown in FIG. 9, for example. On the other hand, in the case where the upright member 62 serving as a pillar is fastened with one screw 63 with respect to 61, when a heavy object is placed on the shelf 60, the load is applied to the end surface 61 of the shelf 60. The upright member 62 fastened in place slides in the direction of rotation around the screw 63 as shown by the arrow, causing the shelf unit to sway in the front-rear direction, and the swaying loosens the screw 63 to fasten the upright member 62. Occurs, and the shelf unit becomes extremely unstable in that it shakes not only in the front-back direction but also in the left-right direction.

For this reason, when the upright member 62 is fastened to the end surface 61 of the shelf 60 with one screw 63, a sway preventing brace (a cross bar or a cross brace) is provided on the back surface of the shelf unit. I have installed a streak) to stabilize the shelf unit.

[0006]

However, if a crossbar is installed on the back of the shelf unit, the overall appearance is not smart and the appearance is not good, and the cost is increased by installing the crossbar. In addition, there is a problem that the number of assembling steps is large and the assembling is troublesome.

[0007] For example, if the number of screws for fastening the uprights to the end surface of the shelf is increased to two, the torque rotating around the screws does not act, so that the shelf unit is shaken without attaching the crossbar. It is possible to prevent this, but since the number of screws used is doubled, there is a problem that it takes more time to assemble the shelf unit than when the crossbar is attached.

Therefore, it is a technical object of the present invention to prevent shaking of the shelf unit without attaching a crossbar even if the connecting portion between the shelf and the upright member is fastened with one screw.

[0009]

In order to solve the above-mentioned problems, the present invention is a shelf unit in which an upright member serving as a pillar is coupled to a corner portion of a shelf or a chest and assembled, and the surface of the corner portion is It is characterized in that it is assembled by a shelf or a chest formed on a corrugated surface that causes unevenness in the left-right direction, and an upright member formed on the corrugated surface that overlaps the corrugated surface on the surface of the portion to be joined to the corner portion.

In the shelf unit according to the present invention, the surface of the corner portion of the shelf or chest and the surface of the upright member to be joined to the corner portion are both formed in a corrugated surface which causes unevenness in the left-right direction, and the corrugated surface is formed. The faces are designed to overlap each other.

Thus, for example, even if the upright member is fastened to the corner portion of the shelf with only one screw, the upright member can be rotated in the direction of rotation about the screw due to the overlapping of the corrugated surfaces. The sliding movement is prevented, and the sliding movement of the uprights is also prevented, which prevents loosening of the screws that fasten the uprights.Therefore, the shelf unit does not need to be reinforced by installing a crossbar on the back. ,
It is kept in a stable state without shaking.
