Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly shelf installed between a floor and a ceiling.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No.
There is a publication No. 30763, in which an upper frame and a lower frame each having a U-shaped cross section are nested and connected in a nested manner to form a shelf frame, and a shelf plate is arranged in a multi-stage shape on the inner surface of the shelf frame. . The entire shelf can be fixed between the floor and the ceiling by adjusting the amount of vertical overlap of the shelf frame and pressing the tension mechanism at the top of the shelf frame against the ceiling.

[0003] In order to support the shelf, a group of two front and rear hook holes are formed on both side walls of the shelf frame, and four shelf holders inserted into and engaged with the hook holes are used to hold the shelf. It supports the four corners of the lower surface. The shelf receiver also serves as a stopper that defines the overlapping limit of the upper frame and the lower frame, and is mounted in a hook hole on the lower frame side to support the lower edge of the upper frame. The shelf holder has a main body part having a right-angled triangular cross section in longitudinal section, a shelf receiving claw protruding upward at an upper side end of the main body part, and an inverted L-shaped hooking claw protruding from a vertical wall of the main body part. It consists of molded plastic products.

[0004]

In the above-mentioned shelf receiver, portions other than the hooks protrude from the inner surface of the side wall of the shelf frame when mounted in the hook holes. In most cases, the shelf is supported by the shelf receiver, so that there is no problem even if parts other than the hooks protrude. However, when the shelf holder is used only as a stopper for receiving the upper frame, the parts other than the hooks protrude greatly. It may interfere with putting things in and out.

When the upper frame and the lower frame are assembled and the tension mechanism is stretched to the ceiling, the weight of the upper frame and the like and the tension reaction force of the tension mechanism act on the shelf support. Further, the weight of all the stored items on the shelf supported by the upper frame is concentrated on the shelf receiver. This large load acts equally on the hook holes of the lower frame and the lower edge of the upper frame supported by the shelf receiver. Therefore, the upper frame and the lower frame, which are obtained by simply bending a thin steel plate into a U-shaped cross section, may deform the contact edge with the shelf support or may be gradually torn, and the connecting portion between the upper frame and the lower frame may be broken. It is difficult to obtain sufficient strength. It is easy to improve the strength by increasing the material thickness of the upper and lower frames, but doing so increases the material cost and processing cost and inevitably increases the product weight.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the structural strength of side frames constituting a shelf, and to improve the load supporting structure of a connecting portion between upper and lower side frames, thereby exhibiting sufficient rigidity while being lightweight. An object of the present invention is to provide an assembly shelf of a fixed tension type. Another object of the present invention is to prevent a stopper fitting for receiving the upper frame from protruding from the inner surface or the outer surface of the side frame, so that it is possible to easily carry out and take out stored articles on the shelf without being disturbed by the stopper fitting. To be able to do it.

[0007]

It is.

[0009]

The upper frame 5 and the lower frame 6 are formed in the shape of a hollow frame, and they are superposed and connected in a nested manner. Therefore, it is not necessary to increase the thickness of the upper frame 5 and the lower frame 6 and connect them. The structural strength of the part increases. Since the upper frame 5 is supported by the stopper metal fittings 22 horizontally hooked into the inner and outer locking holes 9 of the lower frame 6, the number of contact points of the upper frame 5 with the stopper metal fittings 22, and the number of stopper metal fittings The number of contact points of the stopper fittings 22 with the engaging holes 9 can be doubled as compared with the conventional case, and the load applied to each contact point is dispersed by that amount, and
Can be prevented from being deformed.

According to the stopper fitting 22 integrally provided with the knob 26, the knob 26 is grasped with a fingertip,
Since the stopper fitting 22 can be inserted into and engaged with the retaining hole 9, the stopper fitting 22 can be easily mounted in the retaining hole 9 even though the retaining hole 9 is provided at the bottom of the vertical groove 7.

The upper end of the knob 26 is connected to the stopper 22
The reason for projecting above the upper end of the hook hole 9 in which is mounted is to surely prevent the entire stopper fitting 22 from dropping into the space inside the lower frame 6 due to an incorrect mounting method or the like. . Even if the stopper fitting 22 falls into the frame, the upper end of the knob 26 is received by the upper peripheral wall of the retaining hole 9 to prevent the stopper from falling into the frame. The reason why the stopper fitting 22 attached to the retaining hole 9 is formed so as to fit in the inner and outer vertical grooves 7.7 is to prevent the stopper fitting 22 from projecting to the inner surface or the outer surface of the lower frame 6. It is.
