[0002]

2. Description of the Related Art Conventionally, a bracket shown in FIG. In this configuration, the joining surfaces of the back plate, the bottom plate, and the two side plates are welded. Distortions occur in the back plate and the bottom plate due to the welding heat generated at the time of this welding, and there are adverse effects, such as the necessity of machining and a double labor for correcting the distortion. In the worst case, there is a problem of being unusable.

[0003] The technical literature which employs a tenon structure which can be freely assembled in a bracket or a display stand which can accommodate household or lightweight articles is as follows: (1) Japanese Utility Model Registration No. 3043778 There is a shelf device, and (2) a cabinet device disclosed in Japanese Patent Application Laid-Open No. 3-146006. This document (1) is an audio rack, in which a shelf plate is mounted on a base plate with a fixing column and a support rod having a structure fitted therein, and the base plate, the fixed column, and the shelf plate are fixed with screws. It is. (2) a support member is erected on the bottom plate, a back plate, a side plate and a front plate are fitted and erected on the bottom plate via the support member, and the back plate is
An upper plate is provided by being fitted and mounted on the side plate and the front plate, and the bottom plate, the upper plate, the rear plate, the side plate, and the front plate are assembled by screwing to the support member.

[0004]

In the case of welding in a method to be mounted on a machine, it has been described that the above-mentioned problem exists, and therefore a description thereof will be omitted. On the other hand, in the above-mentioned documents (1) and (2), the fitting structure is similar to the tenon structure. In view of the relationship with the articles, it is unlikely that a problem occurs even with this fitting structure. However, as in the present invention, it is conceivable that there is a problem in strength with respect to a bracket provided on a machine for putting heavy items.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the example of FIG. 1, a second mortise in the bottom plate (hereinafter referred to as a second tenon; the same applies to each example).
Then, the first tenon of the back plate is inserted, and the back plate is brought into contact with the end face of the bottom plate, and the back plate is supported or supported by a fall prevention device or means so as not to fall down. In this state, the second and third tenons of the two side plates are respectively inserted into the first mortises of the back plate and the third mortises of the bottom plate. As a result, the temporary assembly of the bottom plate, the back plate, and the two side plates is completed, and then these three members are fixed. That is, each bolt is inserted from the first and second holes for bolt insertion provided on the back plate and the bottom plate, respectively, and screwed into the nuts respectively provided on the two side plates. The back plate, the bottom plate, and the two side plates are fixed through the tightening of the bolts, thereby completing the assembly and fixing of the bracket. The assembled bracket is mounted on the machine using mounting tools such as bolts and nuts (not shown), holding tools, and other mounting means.

In the example of FIG. 3, as in the above-described example, the back plate is brought into contact with and supported by the bottom plate, and a 90 ° base is formed by the bottom plate and the back plate. Thereafter, the left and right cut grooves of the four side plates are aligned with the left and right cut grooves of the intermediate plate, and the intermediate plate and the respective side plates are assembled in a substantially cross shape. The second mortise and third mortise of each side plate are inserted into the first mortise and third mortise of the back plate and the bottom plate constituting the base. As a result, the temporary assembly of the back plate, the side plates, and the four side plates is completed, and then these three members are fixed. That is, each bolt is inserted from the first and second holes for bolt insertion provided on the back plate and the bottom plate, respectively, and screwed into the nuts respectively provided on the two side plates. The back plate, the bottom plate, and the two side plates are fixed through the tightening of the bolts. Then, I attach the front plate,
When the fourth tenon of the front plate is inserted into the fourth tenon of the fixed bottom plate, and the sixth tenon of the front plate is inserted into the fifth tenon of each side plate, each fixed side plate and bottom is fixed. Since the front plate is temporarily assembled on the face plate, the front plate is subsequently fixed to the fixed side plates and the bottom plate. That is, each bolt is inserted from each of the second and third holes for bolt insertion provided on each side plate and bottom plate, and screwed into each nut provided on each side plate. The front plate is fixed to the fixed side plates and bottom plate via the tightening of the bolts, whereby the assembly of the bracket is completed. Subsequent usage is substantially the same as in the above-described example.
