Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a shelf board below a desk top plate between one leg and the other cabinet.

Conventionally, in this type of shelf, the shelf board was attached to the shelf support plate provided on the legs and the cabinet by screws or rivets, which resulted in poor workability and expensive defects.

The present invention eliminates these drawbacks and can be easily and securely installed, and its structure is as follows.

A shelf support plate is fixed to the inner surface of the leg, the shelf support plate having a shelf support part on the lower end edge and a shelf stopper protrusion inside the shelf support part, and the shelf stopper protrusion engages with the shelf support plate. A side window side piece having an engagement hole is engaged with the shelf holder, while a side stone side piece having a locking claw and a protrusion for preventing shelf climbing is engaged with a square hole formed in the cabinet side plate. This shelf mounting device is characterized by:

Embodiments of the present invention will be described below with reference to the drawings.

1 indicates the entire desk, 2 is a cabinet, 3 is a leg, 4 is a shelf support plate attached to the leg 3, and 5 is a shelf attached between the shelf support plate and the cabinet.

The shelf support plate 4 is formed of a thin metal plate into a rectangular shape, and has a protrusion 41 at the front for fixing the shelf support plate 4 to the legs 3.
Reinforced edge 4 by crushing and bending the upper edge and the middle of the rear edge.
2.

On the other hand, the lower end edge is bent upward and the upper end thereof is bent slightly outward to form a tapered U-shape overall.
, and square holes 44 are provided at two locations in the front and rear of the shelf support side piece 441.
I have 2 children.

On the other hand, below the shelf support plate, in a position corresponding to the square hole, there is a shelf support 4.
4, a shelf board rising stop protrusion 46 protruding inwardly and a shelf board movement prevention receiving piece 43 whose rear edge is bent inwardly are constructed.

The shelf board 5 has a front part 59 with the front part of the top surface of the shelf root bent into an L shape.
and the right side window 51.52 with the left and right ends folded downward.
It is composed of a rear piece 53 whose rear edge is bent upward and downward into a U-shape, and the side window side piece 51 has engagement holes 5 in the front and back.
11,512 are provided, and an engagement hole 512 on the rear side is further provided.
An inwardly directed protrusion 58 is provided at the rear of the holder.

The side stone side piece 52 is provided with outward locking claws 56, 56' and shelf climbing prevention protrusions 57, 57' above the locking claws.

a locking piece 55 in which the right end of the rear piece 53 projects outward;
A shelf plate movement prevention protrusion 54 is provided with the left end bent backward.

On the other hand, square holes 22, 23, 24 are provided in the rear lower part of the side plate 21 of the cabinet 2, corresponding to the locking claws 56, 56', the shelf climbing prevention protrusions 57, 57', and the locking pieces 55. There is.

Each member constructed as described above is assembled in the following manner.

Square holes 22゜23. made in the side plate 21 of the cabinet 2.
24, the locking claws 56, 56' and the locking piece 55 of the shelf board 5 are inserted, and after positioning the side window side piece 51 above the shelf support part 44 provided on the support plate 2, the shelf metal body is When pushed downward, the inner surfaces of the locking claws 56 and 56' engage with the lower inner surfaces of the square holes 22 and 23, and at the same time, the shelf climbing prevention projections 57.
The tip of 57' contacts the upper and lower surfaces of the square holes 56, 56',
The side stone side piece 52 and the side plate 21 of the sleeve drawer 2 are firmly connected.

Further, a locking piece 55 is located below the square hole 24 to prevent the shelf board from moving back and forth.

Next, the measuring side piece 51 engages with the shelf support part 44, and the measuring side piece 51 is attached to the lower surface of the shelf rising stop protrusion 46 provided on the shelf support plate 4.
The shelf board 5 is prevented from moving upward by contacting the lower upper surfaces of the square holes 511 and 512 provided therein.

At this time, the protrusion 58 provided on the side window side piece is connected to the shelf holder side piece 441.
Furthermore, the end of the front piece 59 of the shelf board 5 is located at the front end of the shelf support side piece 441.

Also, by positioning the shelf movement prevention protrusion 54 provided on the rear piece 53 of the shelf board 5 in front of the shelf movement prevention receiving piece of the shelf support plate 4, the left side of the shelf board 5 can be prevented from moving back and forth. Prevent movement.

On the other hand, since the upper end surface of the rear piece 53 of the shelf board 5 is located below the reinforcing portion 42 of the shelf support plate 4, the upper end surface of the rear piece 53 of the shelf board 5 is Prevent movement to.

As described above, the present invention is a practical desk shelf support device that is easy to assemble, can be firmly attached, and can be manufactured at low cost.
