Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a device for fixing a shelf board to a support.

[0002]

2. Description of the Related Art Conventionally, a shelf plate fixing device of this kind has a locking hole provided in a column of an L-shaped angle, and Japanese Utility Model Publication No. 55-55.
No. 624 and Japanese Utility Model Publication No. 55-55629, the joint surfaces corresponding to the pillars and the shelf holders attached to the pillars are formed in an arcuate cross section, and the locking pieces are engaged with the engaging holes, so that the shelf plate is used as the pillar. There are things to support. However, these columns are all weak in strength, and the strength is maintained by increasing the material thickness.

[0003]

Problems to be Solved by the Invention In the case of an L-shaped angle or an angle having an arc-shaped cross-section, twisting occurs, so that the material thickness is increased and strength is maintained, so that the weight becomes heavy and the material cost also increases. In addition, the engaging hole provided in the support, the screw head for attachment, and the like appear on the outer peripheral portion, so that the appearance is not good. SUMMARY OF THE INVENTION It is an object of the present invention to provide a column which can maintain strength by a thin plate material and a shelf fixing device which does not impair the aesthetic appearance.

[0004]

The outer portion of an inner plate in which a plurality of sets are arranged alternately with engaging holes and screw insertion holes is alternately covered with an outer plate of an L-shaped curved plate and integrated to form a support. I do. The shelf mounting bracket has upper and lower extruding tongues opposed to each other at the upper and lower portions of the central surface, and a shelf holding plate extending at an inner angle of 135 degrees on each of the left and right portions.
The support plate and the shelf-mounting bracket clamp the shelf plate corner so that the push-out tongue of the shelf-mounting bracket engages with the engaging hole of the support, and screws are inserted from the inside of the shelf through the screw insertion holes of the support. It is configured to be fastened to the screw hole at the center of one side.

[0005]

[Function] The post is integrated with the outer plate so as to wrap the left and right peripheral edges of the inner plate, and the engaging hole and the screw insertion hole are hidden, so that the screws are not visible from the surroundings, and the aesthetic appearance is harmonized with the shelf plate. . Further, the horizontal cross section becomes substantially triangular, and the strength in the horizontal direction is obtained, and there is no torsion, and a sufficient shelf board supporting force can be obtained by thin plate processing.
To attach the shelf, the corner of the shelf is sandwiched between the support and the shelf mounting bracket, the extruded tongue of the shelf mounting bracket is engaged with the engaging hole of the support, and the engaging portion is screwed with a screw. Therefore, the strength of the assembly shelf is maintained without the shelf plate falling off or the mounting portion being rattled.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an exploded perspective view of a main part of the shelf board mounting. A corner portion of the shelf board T is provided with an oblique cutout opening so that the column 1 and the shelf mounting bracket 2 can be engaged.

[0007] The strut 1 comprises an inner plate 1d and an outer plate 1a,
The inner plate 1d bends the left and right ends along the longitudinal direction of the strip at an inner angle of 135 degrees with respect to the center plane, and alternately has an engagement hole 1b and a screw insertion hole 1c on the center plane. The outer plate 1a has a shape in which the right-angled portion of the L-shaped support is curved, and the outer plate 1a is integrated with the inner plate 1d by covering the left and right bent surfaces from the back of the inner plate 1d.

[0008] The shelf mounting bracket 2 has a center surface 2b having a width capable of coming into contact with the center surface of the inner plate of the column through the cutout opening of the shelf plate, and the upper and lower portions of the center surface 2b have the thickness of the inner plate 1d. The extruded tongue pieces 2c, 2c extruded by a certain amount are engaged with the engagement holes 1b of the column 1,
1b so as to engage with the tongue piece 2
c and 2c are provided with screw holes 2d and 2d, respectively.
When c and 2c are engaged with the engagement holes 1b and 1b, the screw insertion holes 1
It is configured such that the centers of c and 1c and the screw holes 2d and 2d coincide. A shelf holding plate 2a extends left and right across the central surface 2b, and a reinforcing surface 2f extends below each of the engagement grooves 2e into which the lower bent edge of the shelf engages. I have.

FIG. 2 is a perspective view showing a main part in a state where the shelf board is mounted. The extruding tongue piece 2c of the shelf mounting bracket 2 is supported by the column 1 by clamping the corner of the shelf board between the column and the shelf mounting bracket. The screw 3 was screwed into a screw hole 2d formed in the center of the extruded tongue piece 2c through the screw insertion hole 1c of the column through engagement with the engagement hole 1b, and the shelf plate was attached to the column.

FIG. 3 is an exploded perspective view showing one corner portion of a shelf on which shelves are provided in three stages. FIG. 4 is a vertical cross-sectional view of a corner portion in a state where a shelf board is mounted.
The screws 3 and 2c are engaged to screw the screw 3 into the screw hole 2d via the screw insertion hole 1c.

[0011]

[Effects of the invention] The support pillar is made by integrating the inner plate and the outer plate, so that the mounting holes and screws are not visible from the outside, without disturbing the aesthetic sense of the surroundings. High strength due to high strength. High strength can be obtained even when using thin materials. The mounting of the shelf is such that the upper and lower extruded tongues are engaged with the columns at each corner, and the tongues engaged with the columns are tightened and fixed with screws. Is obtained.
