Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a shelf support device for supporting a shelf to a shelf support plate protruding from a shelf post or the like.

[Conventional technology]

Prior art for this type of shelf support device includes:
There is one described in Utility Model Publication No. 59-34372.

That is, in this prior art, as shown in FIGS. 13 and 14, a locking tool 10 having a downward U-shaped cross section is fitted onto the upper edge of a shelf support plate 11 that protrudes from a shelf pillar or the like. A horizontal support plate 10a is integrally formed at the lower end of one side plate 10d of the locking tool 10, and a shelf plate 13 is formed on the upper surface of the support plate 10a.
On the other hand, a positioning piece 10c is integrally bent and formed on the other side plate 10b of the locking tool 10, and the positioning piece 10c is formed in a locking hole 11a drilled in the shelf receiving plate 11. By engaging the locking tool 10 with the shelf support plate 11
It is positioned so as not to be movable in its longitudinal direction. In addition, the code|symbol 12 is a connection member for connecting between the pair of left and right shelf support plates 11.

[Problem that the invention attempts to solve]

However, in the prior art, of the left and right side plates 10d and 10b of the downward U-shaped cross-section locking device 10, one side plate 10d is provided with a support plate 10a on which the shelf board 13 is placed, and the other side plate 10b is provided with a support plate 10a. , since the positioning piece 10c for the shelf support plate 11 is provided, this positioning piece 10c is attached to the support plate 1.
It will be located at a portion facing the end surface of the shelf board 13 placed on the upper surface of the shelf board 0a.

Therefore, when the protruding length of the positioning piece 10c is long, it completely penetrates the locking hole 11a and protrudes inside the shelf receiving plate 11, so that the shelf receiving plate 1
1, but on the other hand, when the shelf board 13 is placed on the upper surface of the support plate 10a, the protruding end of the positioning piece 10c from the shelf support plate 11 is secured against the shelf board 13. Since it will come into contact with the end surface, it is necessary to leave a gap of relatively large size S between the shelf board 13 and the shelf support board 11. This will cause items to fall.

In this case, in order to narrow the gap between the shelf board 13 and the shelf support board 11, the protruding length of the positioning piece 10c must be shortened.
Since the positioning piece 10c fits shallowly into the locking hole 11a, the locking hole 1 of the shelf support plate 11
This makes it easier to disengage from the engagement with 1a.

Moreover, in the prior art, one of the left and right side plates 10d and 10b of the locking tool 10 is provided with a support plate 10a, and the other side plate 10b is provided with a supporting plate 10a.
Since the positioning piece 10c is provided in the configuration,
Since it is not possible to provide the same support plate 10a as the one side plate 10d to the other side plate 10b, when attaching two shelf plates on the left and right sides of one shelf receiving plate, cannot be applied, and in addition, the positioning piece 10c cannot be applied.
Since a separate bending step is required to bend and form, the cost increases.

The present invention aims to solve the problems of the prior art as described above.

[Means for solving problems and their effects]

Therefore, in the present invention, a locking tool made of a metal plate having a downward U-shaped cross section is fitted onto the upper edge of a shelf support plate protruding from a shelf pillar, etc., and at least one of the side plates of the locking tool is A shelf support device configured to integrally form a horizontally bent substantially horizontal support plate at the lower end of one of the side plates, and to place a shelf on the upper surface of the support plate. In the support plate, an extension portion extending in the longitudinal direction of the shelf support plate while maintaining the same substantially horizontal shape is integrally formed, and a locking hole drilled in the shelf support plate is formed in the extension portion. The fitting positioning piece is formed in the same plane as the support plate and the extension part, and is integrally formed.

That is, in the present invention, the positioning piece for the locking tool fitted on the shelf receiving plate is extended from a substantially horizontal support plate formed on one side plate of the locking tool while maintaining the same substantially horizontal surface. In addition, by forming the support plate and the extension part on the same plane, the positioning piece is always located below the bottom surface of the shelf board placed on the top surface of the support piece. Even if the protruding length of this positioning piece, that is, the length by which the positioning piece fits into the locking hole in the shelf support plate is increased, it will never come into contact with the end surface of the shelf board.

In addition, by forming this positioning piece in the same plane as the support plate and the extension part as described above,
This positioning piece is for the deployed state of the locking tool.
Since the shape can be formed at the same time when punching out the plate material, there is no need for bending to form the positioning piece as in the prior art. It is also possible to integrally form a horizontal support plate with its lower end bent laterally on the face plate.

[Effect of idea]

Since the present invention has the configuration described in the claims for utility model registration, it produces the following effects.

The positioning piece for immovably locking the locking tool fitted onto the shelf support plate is always located below the bottom surface of the shelf placed on the top surface of the support piece. However, even if the protruding length of this positioning piece, that is, the length of the fitting into the locking hole in the shelf support plate, is increased, it will never come into contact with the shelf board, so the locking tool cannot be attached to the shelf support plate. The gap between the shelf board and the shelf support board can be narrowed while being able to be positioned reliably and firmly against the shelf board.

The positioning piece of the locking tool can be formed at the same time as the expanded state of the locking tool is punched out from the plate material, and bending is not required to form the positioning piece as in the prior art. Since it is not necessary to do so, manufacturing costs can be reduced.

Since a support plate can be provided on the other side plate of the locking device to support the shelf plate, as shown in FIG. It can also be applied when installing two shelf boards arranged on both sides.
