Through holes (27) and (27) are formed in b) and respectively.

In the fitting hole (26) of each column (2), the same fixture (12) as described above is fitted and locked in the same manner as described above.

The lower horizontal connecting rod (4) is provided with an upper piece (28) provided at the center of the upper surface with a concave groove (28) serving as a receiving groove when a rear plate (not shown) is used (not used in this example). 4a) and hanging pieces (4b) (4b) hanging from the front and rear edges thereof, and the cross-sectional shape is substantially downward U-shaped.

Reinforcing members (29) which are vertically symmetrical with the above-mentioned reinforcing member (19) are fixed to the upper surfaces of the left and right ends of the lateral connecting rod (4).

This reinforcing member (29) is the same contact piece as described above.
(29a) and a pair of front and rear side pieces (29b) which are bent at right angles inward from the front and rear ends thereof and whose lower ends are welded to the upper piece (4a) of the lateral connecting rod (4). (29b) and contact piece (29a)
In the middle part, a slit-shaped locking hole (30) for allowing the protruding piece (13) of the fixture (12) to pass through is provided at a portion substantially corresponding to the fitting hole (9) of the inner piece (2a). ) Has been drilled.

The same engaging tool (22) as described above is fixed to the upper edge of the locking hole (30) on the inner surface of the contact piece (29a) in the same manner as described above.

On the lower surfaces of the left and right end portions of the horizontal connecting rod (4), the upper end portions of the connecting members (31) whose plane shape is a substantially inward U-shape are fixed. Therefore, each end portion of the horizontal connecting rod (4) has a lateral T-shape in a front view by the upper reinforcing member (29) and the lower connecting member (31).

The connecting member (31) is substantially flush with the side end of the lateral connecting rod (4) and the contact piece (29a) of the reinforcing member (29), and the inner piece (2a) of the column (2). Abutment piece (31a) that is abutted against the inner surface of each hanging piece (4b) of the lateral connecting rod (4), which is bent at a right angle inward from its front and rear ends and has an upper end outer surface. It consists of a pair of front and rear side pieces (31b), (31b) welded to each other.

The abutting piece (31a) has an upper portion with a notch on both sides thereof, and a downward hook (3
2) (32) has been cut and raised. A through hole (33) is formed in the center of the contact piece (31a) below the hooks (32) and (32).

The left and right ends of the horizontal connecting rod (4) are
The hooks (32) and (32) are attached to the front and rear of the column (2) so that the respective end faces and the contact pieces (29a) and (31a) contact the inner surface of the inner piece (2a) of the column (2). Fit and lock into the engaging holes (25) and (25) of the
The bolt (34) is inserted from the outside piece (2b) side of (2) into the through holes (27) and (33), and the nut (35) is screwed and tightened at the tips of the bolts (34) to support the column (2). It is firmly connected to the bottom of.

At this time, the engaging hole (23a) of the engaging tool (22) is
From above, the fixing member (12) is fitted into the upward projecting portion (14), and the reinforcing member (29) is firmly locked to the column (2).

In this way, the bolt (34) and the nut (35)
Thus, a fastening means for the connecting member (31) is formed.

As described above, the lower horizontal connecting rod (4) is formed by the reinforcing member (29) and the connecting member (31) so that each end has a T shape in the horizontal direction when viewed from the front, and the inner surface of the column (2). Since they are abutted against each other and are fastened to the columns (2) by the fastening means, a stronger coupling force can be obtained than the connection structure of the upper lateral coupling member (3) to the columns (2).

In addition, reinforcing members (19) (19) having a triangular shape in a front view are provided at all inner corners of the connecting portion between the left and right columns (2) (2) and the upper and lower horizontal connecting rods (3) (4). (29) Since (29) is provided, it is possible to maintain sufficient strength against rolling and the like without providing a back plate or braces.

Further, the same 2 as shown in FIGS.
The individual frames (1) (1) may be connected to each other in the left-right direction to form a horizontally long display shelf or the like. In this case, the left and right frames (1) (1) are
(2) It is advisable to bring the side surfaces of (2) into contact with each other and screw a long bolt forming a fastening means into the nut (35) on the inner surface of the connecting member (31) to fasten them together. As a result, the left and right frames (1) and (1) can be connected at the same time when the columns (2) and the connecting member (31) are fastened.

[0043]

According to the first aspect of the present invention, the hooks are locked in the engaging holes so that the side ends of the upper horizontal connecting rod and the reinforcing member come into contact with the facing surfaces of the support columns, and Since the upper protrusion of the protrusion provided on the pillar is locked to the upper edge of the locking hole of the reinforcing member, it is particularly strong against lateral vibration of the pillar,
Even without providing a back plate or braces, sufficient strength can be maintained, and it is possible to easily and firmly assemble without using fastening means such as bolts, and disassembly is easy.

According to the second aspect of the present invention, the reinforcing member is provided more upwardly than when the upward protruding portion of the protruding piece protruding from the support is directly engaged with the inside of the upper edge of the engaging hole of the abutting piece of the reinforcing member. Can be more strongly prevented from leaving the column, and the strength of the connection between the column and the upper horizontal connecting rod can be increased.

According to the third aspect of the present invention, the projecting piece can be easily attached to and detached from the supporting column, and once attached to the supporting column, the projecting piece will not be unintentionally disengaged, and the projecting piece has a locking hole for the reinforcing member. By locking the upper edge, it is possible to easily assemble and disassemble the column and the lateral connecting rod without using any fastening means such as bolts and nuts.

According to the invention as set forth in claim 4, since the lower horizontal connecting rod is connected to the left and right columns in the same structure as the upper one, the upper and lower balance of the completed frame is good, and each column and the horizontal are good. Reinforcing members are provided at the inner corners of the connecting portion with the connecting rod, and they are firmly locked to the support columns, so that sufficient strength is maintained that is not inferior to the case where a back plate or braces are provided. be able to.
