[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a top plate mounting device in a box-shaped cabinet having a front opening.

[0002]

2. Description of the Related Art The most common means for attaching a top plate to a cabinet in a cabinet with a front opening such as a filing cabinet or a side desk is to insert a screw from below the inward flange on the top surface of the cabinet. , It is to fasten the four corners of the lower surface of the top plate.

Further, as described in Japanese Utility Model Laid-Open No. 2-121828, for example, a daruma-shaped hole facing in the front-rear direction is provided on a cross rail at the rear of the upper surface of the top plate, and a corresponding portion on the lower surface of the top plate. Then, screw the engaging pin having the expanding head at the lower end, insert the expanding head from above the large diameter part of the dharma-shaped hole, and move the top plate in the front-back direction to engage the engaging pin. the shaft portion, engaged to the small diameter portion of the dharma-shaped holes, then the lower surface front portion of the top plate, some of which were adapted to fastened to the upper surface of the housing with screws.

[0004]

In the former case of the above-mentioned conventional example, it is necessary to put the hand inside the casing to carry out the work, and therefore the work of fixing the screw to the rear portion of the top plate is not easy. Also in the latter, it is not easy to fit the expanding head of the pin into the dharma-shaped hole, and thus the work is rather cumbersome and inefficient.

An object of the present invention is to solve the above-mentioned problems in the conventional top plate mounting device for the cabinet body.

According to the present invention SUMMARY OF THE INVENTION The locking bracket provided on the rear end, substantially horizontally such to post pieces subsided (21)
(20) is locked to the rear part of the lower surface of the top plate (2) and is attached to the housing (1).
After the notch (7) at the front edge of the rear crosspiece (6)
The rear piece (21) of the locking metal fitting (20) is superposed on the lower surface of the side of the top plate (2) so that the rear part of the top plate (2 ) is fixed to the housing (1) and the housing (1) Hold the set screw (28) inserted into the front cross rail (4 ) of the housing (1) from the front opening of the top plate (2).
The above problem is solved by fixing the front part of the to the housing (1) .

[0007]

[Function] After attaching the locking metal to the lower surface of the top plate, the top plate is locked to the rear cross rail of the housing, and then only the front portion of the top plate is fastened to the housing with the set screw. The board is securely attached.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, (1) is a housing with an open top and front, (2) is a top plate that covers the top of the housing (1), and (3) is the front of the housing (1). It is a drawer inserted from.

Through holes (5) and (5) are formed near the left and right ends of the front cross rail (4) of the housing (1), and the rear cross rail (6) also has a rear hole near the left and right ends thereof. the facing rectangular switching inclusive (7) (7) is provided.

The top plate (2) is a hollow flat closed box made of blow-molded synthetic resin, and the nut (8) is provided at the position corresponding to the through holes (5) (5) in the front part of the lower surface. (8) is buried, and in the rear part of the lower surface, a shallow upward concave groove that faces the left-right direction.
(9) is formed.

At the rear portion of the upward recessed groove (9), a horizontally long mounting metal member (10) is fixed by an appropriate number of rivets (11).

The mounting bracket (10) is an upward U-shaped channel (12).
From the upper edge of the rear side piece (13), connect the horizontal rearward piece (14),
The parts corresponding to the respective switching included in the rear direction member (14) (7), flush with the bottom piece of the upward arcuate channel (12) (15), and notch hole slightly wider than (7) subsidence The square hole (17) is provided at a key part of the sinking part (16), and in the front of the square hole (17), the upward U-shaped channel (12) is formed.
At the lower end of the vertical piece (18) on the front side , a horizontally long flat hole (19)
Has been drilled.

A rear piece (21) and a front piece (22) of the locking fitting (20) are fitted and locked in the square hole (17) and the flat hole (19), respectively.

More specifically, the locking metal fitting (20) is shown in FIG.
So that the hanging piece (23) from the rear edge of the almost horizontal front piece (22),
Rear direction intermediate piece (24) from its lower edge, suspended piece than its trailing edge (2
A rear piece (21), which is substantially horizontal from the lower edge thereof, is connected to the lower edge (5), and a tongue piece (26) is hung on the rear edge of the rear piece (21).

Locking pieces (27) and (27) facing upward and rearward are cut and formed at important points on both sides of the front piece (22). The locking piece (27) may be provided at the center of the front piece (22).

When the front piece (22) is inserted from below the rectangular hole (17) and the front end thereof is projected from the flat hole (19), the locking piece (2
7) The rear edge of (27) is locked to the upper edge of the front surface of the flat hole (19), and the rear hanging piece (25) is locked to the front edge of the rectangular hole (17), and the locking metal fitting ( 20) is retained and retained.

When the top plate (2) to which the locking metal fitting (20) is attached as described above is placed on the upper surface of the housing (1) and pushed backward, the rear piece ( 21) is the rear cross rail of the housing (1)
The cut (6) is superposed on the lower side of the trailing edge (7). This allows
The rear part of the notch (7) in the rear cross rail (6) is sandwiched between the sinking part (16) of the mounting bracket (10) and the rear piece (21) of the locking bracket (20) to form the top plate (2). ) The rear part is fixed to the rear part of the housing (1).

Then, from the front opening of the housing (1), a set screw (28) is inserted through the through hole (5) of the front cross rail (4) to the top plate (2).
The front part of the top plate (2) is securely fixed to the housing (1) by screwing it into the nut (8) at the front part of the.

[0019]

[Effect of the invention] (a) the top plate is to be guided by <br/> switching included in the locking bracket and the housing, the positioning is extremely easy.

(B) Since no manual work is required on the rear part of the housing where it is difficult to put in the hand, and the screwing work is performed only on the front part of the top plate, the work efficiency is good.

(C) Since the locking metal member is formed separately from the top plate, the locking metal member can be removed and the top plate can be made completely flat for transportation and storage, which is convenient. is there.

(D) Even if the top plate is made of synthetic resin or the like, the strength of attachment to the housing can be increased by making the locking metal fitting durable such as metal.
