BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view, partially broken away, showing one embodiment of a frame connecting structure for an assembling type display fixture according to the present invention. As shown in the figure, the frame connecting structure includes a pair of left and right rectangular tubular supports (1), (1), a lower cross beam member (2) connecting the supports (1), (1) to each other, Leg members (3) (3) attached to the lower end of (1) in the front-rear direction
And more.

The strut (1) has a hollow rectangular cross section made of steel as clearly shown in FIG. 2, and a plurality of slit holes (4) for supporting a shelf support are provided on one side of the front surface thereof. They are arranged vertically. A downwardly facing U-shaped engaging groove (5) is cut in front and rear surfaces of a lower end of the column (1), and a square fitting hole for inserting the cross beam member (2) is formed in the inner surface. (6) is drilled with its lower end at substantially the same height as the upper end of the engagement groove (5).

As shown in FIG. 3, the cross beam member (2) has a hollow square cross section made of steel similar to that of the column (1), and both ends thereof are provided with the fitting holes (1) of the column (1). 6), and the upper wall of this fitting portion is perforated at a position substantially at the center of the column 1, and a nut 7 is provided on the lower surface of the upper wall at the perforated position. Are welded to form a female thread portion. A notch (8) is formed on the lower wall surface of the cross beam member (2) corresponding to the female thread portion, the cutout facing inward from the outer edge.

As shown in FIG. 4, the leg member (3) is a hollow steel member having a square cross section which can be properly fitted into the engaging groove (5) of the support (1). Casters (9) are attached to both ends, and a round hole (10) is formed in the center of the upper and lower surfaces.

As shown in FIG. 5, the end of the cross beam member (2) is inserted into the fitting hole (6) on the inner surface of the left and right columns (1), and the welded nut (7) is attached to the column (1). 1) The periphery of the fitting hole (6) and the cross beam member (2) are set to the
Weld as shown by (w).

The left and right columns (1) are packed together with a horizontal beam member (2) and, if necessary, the upper ends of the left and right columns (1) are connected to each other with an upper connecting member. Bring in.

The following procedure is used for assembling at the installation site. As shown in FIG. 6, the central part of the leg member (3) is fitted into the engagement groove (5) at the lower end of the column (1) and fixed to the round hole (10) on the lower surface of the leg member (3). A bolt (11) is inserted from below through a flat washer and screwed into a nut (7) welded to the lower surface of the upper wall of the cross beam member (2). As a result, the upper surface of the leg member (3) comes into close contact with the lower wall surface of the cross beam member (2), and the leg member (3) is securely and firmly fixed to the column (1).

In the modification shown in FIG. 7, the nut (7)
Are welded to the upper surface of the lower wall of the cross beam member (2). Therefore, except that the fixing bolt (11) is shortened, it is the same as the above-described embodiment.

[0018]

According to the present invention, the following effects can be obtained. According to the first aspect of the present invention, the transportation efficiency can be improved, and the assembling can be performed easily and easily with less man-hours and labor for assembling at the site than before.

According to the second aspect of the present invention, the leg member can be engaged with the column with good positional stability, and a strong structure can be obtained.

According to the third aspect of the present invention, since the fixing bolt covers the entire height of the cross beam member, it is possible to form a structure with less deflection and twist.

According to the fourth aspect of the present invention, the leg member can be fixed to the cross beam member by the fixing bolt having a relatively short length.

According to the fifth aspect of the present invention, a female thread having a sufficient length can be easily and easily formed.
