BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a basic structure of the present invention; FIG. It is an angled support which is curved so as to cover the corner of the shelf (S) from the plate, and a pair of right and left vertical sides (10) which are substantially orthogonal to each other in plan view and both vertical sides (1).
0) A flat or slightly outwardly convex corner surface (11) interposed at the boundary of (0), and the corner surface (11) is provided with a plurality of steps of bolts for maintaining a constant vertical pitch. While the fool holes (12) are distributed in the openings, bent pieces (13) are bent inward at substantially right angles from the lateral edges of the vertical side surfaces (10).

The shelf plate (S) has an overall wide inverted U-shape of a flat rectangular article mounting surface (14) and a vertical side surface (15) bent downward at a right angle therefrom. The vertical side surface (15) is folded upward and inward from the lower edge to the inside to be further inverted and integrated. Thus, while using a thin steel plate or the like as a material, the strength is increased and the fingertip is prevented from being injured.

Further, the vertical side surface (1) of the shelf (S) is provided.
A guide notch (16) for bending is formed at a substantially right-angled corner of (5), whereby the vertical side surface (15) corresponds to both vertical side surfaces (10) of the column (P). It is separated into a left and right pair. The guide notch (1
The opening width of 6) is the corner surface (1) of the support (P).
It is dimensioned to be equal to or smaller than the band width of 1). Despite its narrowness, it is possible to allow the shaft of the bolt (B) to escape.

Reference numeral (17) denotes a pair of left and right projection receiving holes formed in the vicinity of the corners of both vertical side surfaces (15) so as to face each other with the guide notch (16) therebetween. It is elongated and has a substantially elliptical shape, and performs an adjusting operation in assembly.

(A) is a corner fixing bracket for assembling and fixing a corner portion of the shelf (S) to a desired height position of the column (P), and the column (P) and the shelf (S). Pressing as an overall substantially V-shaped curved wing piece form that can be fitted from the inside to the two perpendicular side surfaces (15) that are substantially perpendicular to the shelf plate (S) from a thicker steel plate than from the inside. It has been processed. (T) shows the thickness of the corner fixing bracket (A).

(18) is a pair of right and left vertical plate surfaces that are substantially orthogonal to the corner fixing bracket (A), and the height (h1) of the vertical side surface (15) of the shelf plate (S) is high even if the height (h1) is high. It is determined almost equal to the height (h2),
Similarly, the overall width (w1) of both vertical plate surfaces (18) is smaller than the width (w2) of the column (P). Therefore, the corner fixing bracket (A) is not exposed to the outside from the shelf (S) or the support (P) at all during use, and the entire steel shelf can be maintained in an elegant appearance.

The boundary between the two vertical plate surfaces (18) in the corner fixing bracket (A) is flat or slightly outwardly curved so as to correspond to the corner surface (11) of the column (P). It is formed as a corner surface (19). At approximately the center of the corner surface (19), there is formed a screw hole (20) for fastening a bolt, which fits into the stud hole (12) for receiving the bolt of the support (P).

The screw hole (20) may be directly tapped to the corner surface (19) of the corner fixing bracket (A), but burring of the corner surface (19) prior to the tapping process is performed. Accordingly, it is desirable to form the screw hole (20) as deep as possible.

(21) is a conical stopper protruding outwardly protruding from the corner surface (19) of the corner fixing bracket (A) as a pair of upper and lower portions facing each other so as to sandwich the screw hole (20). When the bolt (B) is tightened, the bolt (B) comes into contact with the corner surface (11) of the support (P) from the inside to guide the tightening margin (end point of the tightening degree) of the bolt (B). However, installation of the stopper projection (21) may be omitted. It is preferable to use a hexagonal bolt with an overhanging flange (22) as the bolt (B).

(23) From the middle of both vertical plate surfaces (18) in the corner fixing bracket (A), the screw holes (2)
0) are engaging projections that are cut and raised outwardly as a pair of left and right parallel to each other so as to sandwich the same, and engage with the projection receiving holes (17) of the shelf (S) from the inside during assembly. The anti-sway effect is achieved.

The two engaging projections (23) have a symmetrical form and are cut and raised from both vertical plate surfaces (18) as long as they engage with the projection receiving holes (17) of the shelf (S). Alternatively, the two vertical plate surfaces (18) may be formed in a cylindrical shape by burring, and may be projected outward.

(24) Pressing claws bent and distributed at an acute angle (θ) outward as a pair of right and left four corners from the lateral corners (four corner positions) of both vertical plate surfaces (18). During assembly, both vertical side surfaces (15) of the shelf board (S) are pressed from the inside, and the both vertical side surfaces (15) are sandwiched and fixed between the pillars (P).

Each of the pressing claws (24) is bent outward from the horizontal bent ridge line (x), and a relief notch (25) for bending is formed on the side of both vertical plate surfaces (18). Although it is provided at the corners, under the scattered arrangement state, as long as it can come into line contact with both vertical side surfaces (15) of the shelf board (S) from the inside and press it, Each pressing claw (24) is bent outward from the vertical bending ridge line (y) as shown in the first modified embodiment of FIG. 8, or is inclined as shown in the second modified embodiment of FIG. Each of the pressing claws (24) may be bent outward from the bending ridge line (z). Further, as a conical projection type pressing claw (24) as shown in a third modified embodiment of FIG. 10, the pressing claw is protruded outward from the lateral corners of both vertical plate surfaces (18). (2
4) may be point-contacted from the inside to both vertical side surfaces (15) of the shelf (S), and it may be determined that this can be pressed.

In this case, a pair of left and right pressing claws (24) as shown in a fourth modified embodiment of FIG. 11 are used as a total of two pressing claws (24) from the lateral edges of both vertical plate surfaces (18). Of the shelf plate (S) from the inside and presses it. It is also possible.
In any case, the corner fixing bracket (A) can be assembled and used without distinction between the upper and lower parts.

When assembling the shelf (S) to the column (P) using the corner fixing bracket (A) of the above-described basic embodiment, as is apparent from FIGS. The strut (P) is overlapped from the outside on the corner portion of S), and the fixing bracket (A) is similarly overlapped from the inside on the corner portion. At this time, the engagement between the two vertical plate surfaces (18) in the corner fixing bracket (A) is performed. The projection (23) is inserted into the projection receiving hole (17) of the shelf (S) and engaged therewith.

The screw hole (20) of the corner fixing bracket (A) and the stupid hole (12) of the column (P) are matched, and the screw hole (2) is inserted through the stupid hole (12) from the outside.
0), one bolt (B) is screwed in and tightened and fixed.

Then, as the bolts (B) are tightened, both vertical plate surfaces (1) of the corner fixing bracket (A) are tightened.
8) Both vertical side surfaces (15) of the shelf plate (S) are pressed from the inside by the pressing claws (24) projecting outward from the inner surface of the support plate (P) with the two bent pieces (13) of the column (P). In combination with the positioning engagement between the engaging projection (23) of the corner fixing bracket (A) and the projection receiving hole (17) of the shelf plate (S). The entire shelf (S) is assembled and fixed to the column (P) in a stable and robust restraint state without any risk of the corner fixture (A) swinging, the shelf (S) becoming uneven, or deforming. It is done.

In this case, the engaging projections (23) of the corner fixing brackets (A) are located at symmetrical distribution positions separated from the fastening point fixed by the single bolt (B). From the tightening and fixing point of the two engaging projections (23)
Left and right symmetric pressing claws (24) are also scattered and distributed at the four corner positions of the two vertical plate surfaces (18) which are farther apart than the shelf plate (S) with one bolt (B). Despite the method of assembling to the support (P), it is possible to effectively prevent positional deviation, rattling, distortion and the like of the shelf (S) along the vertical direction and the horizontal direction.

In particular, if a pair of upper and lower stopper projections (21) sandwiching the screw holes (20) is also scattered on the corner surface (19) of the fixture (A), the bolts (B) are tightened. In addition to preventing excess or shortage, the stopper projection (21) abuts on the corner surface (11) of the column (P) when correctly tightened. This has the effect of helping the bracket (A) to steady.
