[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for easily fixing a shelf plate or the like to a bracket provided on a column or the like in a room.

[0002]

2. Description of the Related Art Conventionally, in order to attach a shelf to a support, the shelf is directly fixed to a bracket provided on the support by bolts or the like. Therefore, it is necessary to tighten a number of bolts from below the shelf with a tool. That was a tedious and time-consuming task. An apparatus that addresses this problem is disclosed in the specification and drawings of Japanese Patent Application No. 3-86754 filed by the present applicant.

[0003]

The above-described device is extremely convenient because the above-mentioned troublesome work is not necessary, but when it is necessary to remove the shelf board, it is caught on the front engaging portion of the bracket. A tool such as a screwdriver is required to retract the spring engagement piece.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device which can easily fix a shelf plate to a bracket without using a tool or the like and can easily remove the shelf plate if necessary.

[0005]

According to the present invention, in order to achieve the above-mentioned object, an engaging portion is provided in a rear upper portion of a hollow bracket having an open upper surface, and an engaging portion is provided in a front upper portion of the bracket and a rear end thereof. A fitting having a mating projection is fitted movably back and forth, urged rearward by a spring, and provided on the lower surface of the shelf plate with a fitting which can be fitted into the upper opening of the bracket. And a front end provided with a locking projection that can infiltrate immediately below the engaging portion and a forward concave groove that can engage with the engaging projection.

[0006]

The locking projection at the rear end of the fixing bracket is sneaked directly below the engaging portion at the rear upper part of the bracket, and the engaging projection at the rear end of the locking bracket is fitted into the groove at the front end of the fixing bracket. By fitting the fixing bracket to the opening on the upper surface of the bracket, the shelf board is prevented from moving up, down, front, rear, left and right, is securely fixed to the bracket, and the locking bracket is moved forward against the spring. Thus, the shelf can be easily removed from the bracket by detaching the engagement projection of the locking metal from the groove.

BRIEF DESCRIPTION OF THE DRAWINGS The drawings show one embodiment of the present invention.
Downward hooks (4) protruding from the rear end face (right end face in FIG. 1) of the hollow bracket (3) having an open upper surface are engaged with the vertically long holes (2) formed in (1), The bracket (3) is detachably locked to the column (1).

In the upper rear portion of the bracket (3), a locking pin (5) facing the side forming an engaging portion is fixedly provided, and an operating hole (6) is provided at the lower front.

In the front upper part of the bracket (3), as shown in FIG. 4, there is provided a U-shaped groove-shaped cover (7) having an open lower surface, and a latch (8) covered by the cover (7). Mating, cover (7)
Is fixed to the bottom of the bracket (3) by a set screw (10) penetrating the rear part of the latch (8) and passing through a long hole (9) extending longitudinally in the vertical direction. .

The latch (8) in the cover (7) is slidable back and forth, and is urged rearward by a compression spring (11) provided between its front end and the bracket (3). I have.

At the rear end of the locking member (8), a rearwardly engaging engaging projection (12) is continuously provided, and the upper surface thereof is an inclined surface (12a) inclined downward and rearward. At the front end of the lower surface of (8),
A handle hanging from the operation hole (6) with an extra number provided before and after
(13) is provided vertically.

In the lower surface of the shelf plate (14), at a position corresponding to a position between the locking pin (5) of the bracket (3) and the engaging projection (12),
As shown in FIG. 3, a U-shaped groove-shaped fixing bracket 15 having a width that can be fitted into the upper inside of the bracket 3 is vertically provided with a wood screw 16.

At the rear lower end of the fixing bracket (15), a bracket is provided.
There is provided a rearwardly engaging locking projection (17) directly under the locking pin (5) of (3), and an engagement fitting (8) at the front end.
The front concave groove (18) with which the engaging projection (12) can be engaged is cut out.

The device of the present invention described above, as shown in FIG.
The shelf (14) is inclined slightly backward and downward, and the fixing bracket (15) is positioned above the bracket (3). Stop projection (17)
It infiltrates directly below the locking pin (5) in the upper rear part of the bracket (3).

Then, when the front part of the shelf plate (14) is lowered, the front lower end of the fixing bracket (15) is fixed to the locking bracket (8) of the bracket (3).
On the inclined surface (12a) of the engaging projection (12), the latch (8) slightly advances against the spring (11) due to the weight of the shelf (14),
When the descending concave groove (18) reaches the front of the engagement projection (12), the locking metal (8) is retracted by the bias of the spring (11) and is fixed.
The front end of (5) is engaged with the latch (8), and the shelf (14) is firmly fixed to the bracket (3) so that both the rear and front parts cannot move up, down, front, back, left and right.

The shelf plate 14 fixed to the bracket 3 as described above is engaged with the latch 8 by pulling the handle 13 forward with the finger against the spring 11. Since the mating projection (12) moves forward and is disengaged from the concave groove (18), the shelf board (14) can be removed by an operation reverse to the above.

In place of the locking pin (5), a bracket is used.
It may be a forward projection formed on the rear edge of the upper surface opening of (3).

[0018]

According to the device of the present invention, as described above,
Due to the interaction between the engaging part and the locking metal provided on the bracket and the fixing metal provided on the shelf, the shelf can be firmly fixed to the bracket very easily without using any tools. This is extremely convenient because the fixed shelf can be removed at any time.
