Description

[Detailed description of the invention] In conventional display shelves installed perpendicularly in two directions, special supports are used at the corners, or special connections are made between the corner supports of display shelves in both directions. If you do not use metal fittings to connect the display shelves, if a person or object collides with them or if they are subjected to external forces such as an earthquake, the display shelves will move, creating gaps between the corner pillars or causing the pillars to overlap. Furthermore, there may be a gap between the shelf board at the corner and the back panel, causing the displayed items to fall.

Further, this type of display shelf is troublesome to manufacture, has a large number of parts, and is expensive.

The present invention relates to a corner connecting device that has a back panel for the corner and reliably connects two orthogonal supports without using special supports or connecting metal fittings. This will be explained in detail based on the drawings.

A plurality of square tubular supports 1 are erected at predetermined intervals in two orthogonal directions, and the ridgelines of the opposing rear corners of both supports 1', 1' closest to the orthogonal point are as follows:
The adjacent side pieces 1'a, 1'a of both support columns 1', 1' are in contact at the orthogonal point, and are orthogonal to each other, forming a V-shaped groove in the vertical direction.

The front piece 1b of each support column 1 is provided with a large number of locking holes 2 arranged vertically at equal intervals and arranged in two rows on the left and right at the same height. A plurality of engagement holes 3 are bored at key points.

Reference numeral 4 designates a shelf board, and downward hooks 6, 6 are connected to the rear end of each bracket 5 that supports and supports both sides of the shelf board.

Each bracket 5 is attached to the pillars 1, 1 by locking the downward hooks 6, 6 into locking holes 2, 2, which are formed at the same height in both adjacent pillars 1, 1.

A display shelf is formed by supporting a shelf board 4 with a bracket 5 and attaching a panel 7 that abuts the rear surface of the shelf board 4 to both adjacent supports 1,1.

Reference numeral 8 denotes a corner panel that closes a V-shaped groove formed on the outer surface of the orthogonal part of the display shelf, and the center piece 8a and 45
The side pieces 8b, 8b facing rearward inward at an angle of At corresponding locations, upward hooks 9 are successively provided facing outward at an angle of 90 degrees.

The corner panel 8 connects each upward hook 9 to the engagement hole 3.
By engaging with, it is attached to both supports 1', 1' and at the same time connects both supports 1', 1'.

In the center of the center piece 8a of the corner panel 8, vertically elongated holes 10 are formed in a row vertically at the same height as the locking holes 2 of each support 1.

Reference numeral 11 denotes a corner shelf board having a substantially fan-shape, with brackets 5, 5 fixed to both sides thereof, and a protrusion protruding rearward from the center of the rear surface, which is secured to both pillars 1', 1'. 12 into the vertical hole 10 of the corner panel 8
It is inserted into.

In this display shelf, as described above, the corner supports 1', 1' are connected by the corner panel 8, and the side pieces 8b, which are connected from both sides of the center piece 8a of the corner panel 8, 8b is in close contact with the adjacent side piece 1b of each pillar 1', 1', the connection between the pillars 1', 1' is strong, and even if an earthquake or other external force is applied to the display shelf, both pillars 1' The relative positions of ′ and 1′ change,
There is no gap between the corner shelf board 11 and the corner panel 8.

In addition, the bracket 5 fixed to the corner shelf board 11
The downward hook 6 engages with the locking hole 2 of the column 1', and the protruding piece 12 at the center of the rear surface of the corner shelf 11 engages with the vertical hole 10 of the corner panel 8. , the corner panel 8 will not move up and down or left and right and will not separate from the support columns 1', 1'.

Note that instead of the upward hook 9 of the corner panel 8, a downward hook may be used.
