DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretch-fixed storage shelf which is arranged along a wall surface and is installed and fixed in a stretched state between a ceiling and a floor. In this storage shelf, the height of the shelf can be changed according to the difference in ceiling height.

[0002]

2. Description of the Related Art A storage shelf of this type is disclosed in Japanese Utility Model Laid-Open No. 7-3076.
No. 3 is known. The storage shelf includes an upper frame and a lower frame each having a U-shaped cross section, a tension mechanism disposed at an upper end of the upper frame, a shelf board hooked in both frames, and the like. The lower part of the upper frame and the upper part of the lower frame are nested and connected so that the overall height can be changed and adjusted within a certain range. On the left and right side walls of each frame, hook holes for fitting and receiving shelf supports are provided at regular intervals in two front and rear rows.

The tensioning mechanism includes a square box-shaped guide frame formed by an upper wall of an upper frame and a top plate, a square box-shaped pressing body slidably supported by the guide frame, and a vertically extending and retracting pressing body. It consists of operating bolts, nuts fixed on the guide frame side, and the like. When the bolt is rotated, the pressing body can be advanced (or retracted) by the amount of screwing.

Since the above-mentioned storage shelves mainly include an upper frame and a lower frame and a required number of shelves, the structure of the side frames of the shelves can be simplified, and the entire shelf can be simplified. Can be minimized. However, it is difficult for the upper frame and the lower frame obtained by simply bending a thin steel plate to have a U-shape to obtain sufficient strength. Since the rigidity of the side frame portion in a state where it is assembled as a shelf is small, it is easy to roll. Each of the upper frame and the lower frame needs to be set to have a length equal to or more than half of the ceiling height, so that the frame is easily bulky and the weight increases by the back wall of each frame, so that the distribution cost is high.

As shown in FIG. 6, two sets of storage shelves are installed at regular intervals, and when the shelves are used between the two shelves, the shelves are horizontally aligned at the same height. Can not be hooked. In order to support the shelves at the same height, it is necessary to mount the shelf holders on the side walls of the upper and lower frames from both sides of the holes. This is because individual shelf supports cannot be hooked at the same time. In addition, since the retaining holes and the shelf holders attached to the retaining holes are exposed on the outer surfaces of the side walls of the upper and lower frames, the appearance is lacking, and a part of the clothes may be caught. Insufficient deburring of the retaining holes can lead to accidental injury.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tension-fixed type storage shelf which can improve the structural strength of a side frame portion and exhibit sufficient rigidity when the entire shelf is assembled. Another object of the present invention is that when a shelf is hung between a plurality of storage shelves, the shelves can be arranged in a horizontal line at the same height. You can do it freely,
An object of the present invention is to provide a storage shelf of a fixed tension type. Another object of the present invention is to prevent the shelf receiving member or the engaging groove for the same from being exposed or protruding from the outer surface of the side frame portion, so that the appearance of the storage shelf can be improved, and the side frame portion such as clothes can be improved. An object of the present invention is to provide a storage shelf of a tension fixed type, which can simultaneously prevent the storage rack from being caught.
