SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention is directed to a metal hollow having a mounting piece projecting at right angles to all or part of an outer axial direction of a shaft portion. -Shaped support, a corner fitting having an insertion protrusion inserted into a mounting hole provided at the upper and lower ends of the support, and projecting in a direction perpendicular to the insertion protrusion of the corner fitting at right angles to each other. A pair of connecting projections, and a metal connection pipe having the same shape as the support post, and connecting and inserting connection holes provided at both ends to the pair of connection projections of the corner fitting. It is characterized by the following.

[0006] The present invention also provides four metal hollow columns having mounting pieces protruding in a direction perpendicular to each other at all or in part in the axial direction outside the shaft portion, A corner fitting fixed by inserting an insertion projection into a mounting hole provided at an end, and a coupling projection projecting in a direction perpendicular to the axial direction of the corner fitting and perpendicular to each other, at both ends. Upper and lower four metal connecting pipes into which the connecting holes provided in the parts are inserted and fixed, mounting pieces orthogonal to the axial direction of the respective connecting pipes and projecting at right angles to each other, and mounting pieces of the respective columns. And a lid or a door attached to the outer enclosure.

The drawings show an embodiment of the present invention. In FIGS. 1 and 2, the reference numeral 1 designates a member forming a column, and a corner 1 of a portion exposed to the outside is provided with a radius 1a, and mounting holes 1 are provided at both ends in the axial direction.
It is a hollow member provided with a square through hole 1d constituting b and 1c, and is manufactured by punching like an aluminum sash. The surface is treated with nandialumite. In the axial direction of the support, the mounting pieces 1e, 1 are separated from the outer portion by the thickness of an outer enclosing member described later.
f is projected in the right angle direction. The mounting pieces 1e,
1f is provided in the entire axial direction of the column in the drawing,
It may be provided in a part thereof. In addition, a decorative groove 1g is formed in the axial direction of a portion exposed to the outside of the column 1.

In FIG. 3, what is indicated by the reference symbol 2 is a corner fitting. The corner fitting 2 has a square shape with flat upper and lower surfaces, and a portion which is flush with a portion exposed to the outside of the above-mentioned column 1 is similarly provided with a radius 2a and has the same pitch as that of the column 1. Are formed with a plurality of decorative grooves 2b. In the axial direction of the lower end portion of the corner fitting 2, an insertion projection 2c having the same shape as the mounting holes 1b and 1c inserted into and fixed to the mounting holes 1b and 1c of the column 1 is projected. The connection projections 2d and 2e are provided to project in a direction perpendicular to the insertion projection 2c of the corner fitting 2 and at a right angle to each other. still,
The shapes of the connecting projections 2d and 2e are also square. The corner fitting 2 is preferably a die-cast product, and in the embodiment, the surface is subjected to Nandi nickel processing.

In FIGS. 4 and 5, what is indicated by reference numeral 3 is a connecting pipe. In this embodiment, the shape of the connecting pipe 3 is the same as that of the above-described support column 1, and the corners of the portions exposed to the outside are rounded 3 a, and the connecting holes 3 b and 3 c are formed at both ends in the axial direction. Is formed in a hollow shape having a rectangular through hole 3d, and is manufactured by punching like an aluminum sash. The surface is treated with nandialumite. In the axial direction of the connecting pipe 3, mounting pieces 3 e and 3 f are provided in a direction perpendicular to the outside of the connecting pipe by a thickness of an outer enclosing member described later. The mounting pieces 3e, 3f
Is provided in the entirety of the connecting pipe 3 in the axial direction in the drawing, but may be provided in a part thereof. A groove 3g for decoration is formed in the axial direction of a portion exposed to the outside of the connecting pipe 3.

FIGS. 6 to 8 show a case where a rack is assembled using the above-mentioned rack frame forming material. Using four columns 1 supplied in advance as long objects (approximately 4 m) cut into four appropriate lengths according to the order, insert them into the insertion holes 1b and 1c provided at the upper and lower ends of each column 1. The insertion protrusion 2c of each corner fitting 2 is inserted. Next, eight connecting pipes 3 having the length according to the order are cut out from the same long object as the column 1 and aligned, and the connecting projections 2d, 2e of the corner fittings 2 are inserted into the connecting holes 3b, 3c of the connecting pipes 3, respectively. Is inserted, a rack skeleton 4 as shown in FIG. 7 is formed.
Note that the above assembling method is an example, and is not limited to the order described. The connecting pipe and the corner fitting may be connected first, or the corner fitting and the connecting pipe may be assembled for each support.

Then, the outer rack 5 and the door 6 selected according to the use of wood, plywood, metal plate, etc. are attached around the skeleton 4 assembled in this manner, whereby the assembly rack 7 is assembled. It is something that can be done. Reference numeral 9 denotes an iron plate and other bases. In some cases, casters may be attached to the mobile type instead of the base depending on the application. Each outer enclosing member 5 is fixed to a mounting piece protruding from the column 1 or the connecting pipe 3 using screws or the like, and the door body 6 is pivot pins 8, 8 protruding from the column 1 or the connecting pipe 3. One side will be hinged. There is no limitation on this butterfly direction. Although the illustrated assembly rack is a vertical type, a horizontal type is a lid instead of a door. This lid may be covered, hinged, or any other method.

[0012]

The present invention is configured as described above.
The following effects can be obtained.

According to the first aspect of the present invention, there is an effect that the number of parts is small, and anyone can easily form a rigid rack skeleton of various sizes according to the application easily. When the connecting pipes are made of the same material, it is sufficient that the connecting pipes are cut from long objects according to the order, and it is possible to achieve an effect that various demands can be met.

According to the second aspect of the invention, anyone can easily assemble a durable rigid rack easily, can select the size according to his / her preference, and can meet the demands of various sizes. The effect that can be done can be produced.
