In particular, the present invention relates to a prefabricated rack which is preferably used when placing small items such as shampoo bottles and towels in a dressing room of a bath at home.

[0002]

2. Description of the Related Art Conventionally, as this type of rack, there has been known a rack in which wire shelves are arranged at predetermined intervals between a pair of left and right side frames having a downward C shape. The left and right ends of these wire shelves are directly fixed to corresponding side frames by welding or the like, or fixed by bolts, nuts or other fixing members.

This type of rack is arranged in a bathroom, such as a dressing room in a bathroom, for shampoo bottles, towels,
Small items such as clothes for changing clothes are appropriately placed on a wire shelf for use.

[0004]

By the way, this type of rack is sold as an assembled finished product or as an assembled product.

However, in the case of being sold as the finished product of the former, not only is it bulky to carry, store, and display, but it is also inconvenient for the purchaser to take home.

On the other hand, when it is sold as an assembled product, it can be handled in a compact state and is convenient, but on the other hand, since a mounting member such as a bolt is required, the number of parts is increased and the parts management is troublesome. Not only that, but the assembly work itself becomes complicated. Further, there is a problem that a tool is required for assembling.

The present invention has been made in view of the above background, and an object thereof is to provide an assembling rack which has a small number of parts and can be easily assembled.

[0008]

In order to achieve the above object, the present inventor does not use a mounting member such as a bolt when connecting the left and right frames to the wire shelves, and does not require a tool during assembly. The present invention has been completed by devising a connection structure as described below.

That is, the assembling rack according to the present invention is arranged between a pair of left and right side frames arranged at a predetermined interval and the pair of left and right side frames, and both end portions correspond to the corresponding side frames. A wire rack attached in a detachable manner, each side frame has a main frame having a pair of front and rear vertical frames and an upper end frame connecting upper ends thereof, and a predetermined height of the main frame. In the position, a straight upper connecting bar vertically arranged at a predetermined interval so as to straddle the pair of front and rear vertical frames and a middle portion excluding both ends are bent in a substantially U shape. While the lower connecting bar is formed, the wire rack is bent downward at an appropriate position in the front-rear direction and attached to the side frame. In a state, it is provided with a mounting portion arranged in a downward inclined state toward the rear and a rear surface portion arranged in an upward inclined state toward the rear from the rear end of the mounting portion, and the rear surface portion of the wire shelf is A part of the left and right outermost wires is bent inwardly protruding to have a rear bending convex portion, and a part of the left and right outermost wires of the mounting portion is bent inward to have a front bending convex portion. On the other hand, in the lower connecting bar of the side frame, a bent concave portion bent in an inwardly protruding shape corresponding to the bent convex portion is formed at a position corresponding to the rear curved convex portion of the wire rack, An intermediate portion of the outermost wire in the front-rear direction is inserted from above between the upper connecting bar and the lower connecting bar of the side frame, and the rear bent convex portion connects the lower connected portion via the bent concave portion. Located below the bar By moving the wire rack backward in the state, the rear bending convex portion is brought into a state of being locked to the lower side of the lower connecting bar, and in that state, the front end portion of the wire rack is changed. The front bent convex portion is forcibly moved to the lower side of the lower connecting bar by being pushed down and is locked to the lower side of the connecting bar. .

As described above, in this prefabricated rack, the middle part of the outermost wire of the wire rack in the front-rear direction is inserted from above between the upper connecting bar and the lower connecting bar of the side frame, and By moving the wire rack backward with the rear bent protrusion located below the connecting bar via the bent recess of the lower connecting bar, the rear bent protruding part is located below the lower connecting bar. The front bent convex portion is forcibly moved below the lower connecting bar and is locked to the lower side of the connecting bar by pushing down the front end of the wire rack in that state. Since it is in the assembled state, it is possible to eliminate the need for a mounting member such as a bolt and a tool at the time of assembly.

Also in the assembled state, the rear bending convex portion and the front bending convex portion of the wire rack are locked to the lower side of the lower connecting bar of the side frame, respectively.
Therefore, since the wire rack is firmly fixed to the side frame, even if an upward force is applied to the wire rack, there is no fear that the wire rack will accidentally fall off.

Between the pair of left and right side frames, the wire shelves may be attached in a detachable manner by the above-mentioned attachment structure extending over a plurality of steps.

Further, in order to eliminate rattling caused by unevenness of the lower end of the side frame or the unevenness of the floor when the rack is placed on the floor, the height of each of the lower ends of the side frames is increased. It is desirable to attach an adjustment member.
