Description

[Detailed Description of the Invention] The present invention relates to a desk leg attachment device that allows the legs to be attached extremely easily and reliably.

Next, to explain the details with reference to the figures, 1 is the desk top plate, 2
4 is an axle box having a drawer 2a, 3 is a leg, and 4 is a curtain plate. At the front and rear of the leg 3, mounting plates 5 and 6 each having a cross-sectional shape are protruded, and as shown in FIG. A headed locking pin 7 is protruded from the base of the 5, and a stepped portion 5a',
A mounting piece 8 having a long hole 8a in the center passes through the long hole 8a as shown in FIG.
A triangular retaining protrusion 10 is formed by extrusion molding or the like and protrudes in the same direction as the locking pin 7 on the leg plate portion at the tip thereof.

Further, as shown in FIG. 6, a mounting protrusion 11 is provided at the tip of the rear mounting plate 6 by cutting and bending or the like.

On the other hand, a hook-shaped latching hole 14 with a stop edge 14'' on the side is provided on the outer side of the rear surface of the front reinforcing plate 12 provided on the back side of the top plate 1. An insertion hole 14'' is drilled at the position, which communicates with the vertical hole of the above-mentioned locking hole 14, and a laterally long fitting hole 15 is provided inwardly on the rear surface of the front reinforcing plate 12. A small fitting hole 16 is provided, and a fitting hole 17 is provided on the front surface of the rear reinforcing plate 13 of the top plate 1.

The front and rear mounting plates 5 and 6 of the leg 3 are fitted between the front and rear reinforcing plates 12 and 13, and the insertion plate 14' is fitted in the front part.
The head 7a of the locking pin 7 inserted from the locking hole 14 is locked to the stop edge 14'' on the side of the locking port 14, and the end edge of the mounting piece 8 and the engaging protrusion 10 are respectively inserted into the fitting hole 15. It is fitted and locked in the fitting hole 16, and the mounting protrusion 11 is fitted and locked in the fitting hole 17 at the rear.

(Figures 2 and 3). In FIG. 2, 5'' is a mounting nut fixed to the peripheral edge of the mounting hole 5'.

Since the leg attachment device of the present invention has the above-described structure, when assembling it, first place the top plate 1 upside down on the floor or a suitable table, then loosen the bolts 9 on the front of the legs and attach the mounting pieces 8 to the leg plate. 5a, and while fitting and locking the rear mounting protrusion 11 into the fitting hole 17 of the rear reinforcing plate 13, attach the leg 3.
Fit the front and rear mounting plates 5°6 between the front and rear reinforcing plates 12 and 13 of the top plate 1, and at that time, insert the front locking pin head 7a from the insertion opening 14' of the front reinforcing plate, If the mounting plates 5 and 6 are latched to the stop edge 14'' on the side of the latching hole 14 and the retaining protrusion 10 at the tip is latched to the fitting hole 16 of the front reinforcing plate, the mounting plates 5 and 6 are securely attached to the reinforcing plate 12.13. Since the front mounting piece 8 is moved and fitted into the front fitting hole 15, and the bolt 9 is tightened to lock it in the fitting hole 15, the above-mentioned engagement is achieved. The mating protrusion 10 or the mounting piece 8 prevents the mounting plate 5 from moving laterally, and the locking pin 7 does not come off the locking hole 14, making it possible to firmly mount the mounting plate 5 and to make the mounting extremely easy. .

Moreover, since the mounting piece 8 is always attached to the mounting plate 5 with the bolt 9, there is no risk of it being lost during assembly, which is extremely convenient for assembly work.

Furthermore, the legs 3 can be easily attached to the top plate 1 even when attached to the axle box 2 via the curtain plate 4.

That is, with the top plate 1 placed upside down, the axle box 2 is first fixed to the top plate 1, and then the curtain plate 4 is moved from the inside to the outside (backward) using the attachment point to the axle box 2 as a fulcrum. As the leg 3 is rotated, the mounting protrusion 11 at the rear of the leg 3 is fitted and fixed in the rear fitting hole 17, so if the front part of the leg 3 is further rotated outward about this point, The head 7a of the locking pin of the front mounting plate 5 is locked in the locking hole 14, and the engagement protrusion 1 at the tip of the mounting plate
0 is fitted and fixed in the fitting hole 16, so it is only necessary to fit and lock the mounting piece 8 into the front fitting hole 15 as described above.

In this case, since the mounting plate 5 is reliably positioned and fixed by the locking pin 7 and the engagement protrusion 10 as described above,
Subsequent operations such as fitting and tightening the mounting pieces 8 become extremely easy, and displacement of the mounting plate 5 during tightening is completely prevented.

FIG. 8 shows another example of the mounting protrusion 11, and a locking pin or the like may be fixed to the mounting plate 6.

The same effect can be obtained even if the mounting mechanism using the mounting protrusion 11, the mounting mechanism using the locking pin 7 and the engagement protrusion 10, etc. are provided on either the front or rear mounting plates 5, 6.

Further, the legs 3 may be panel-shaped legs as shown in the figure, and the present mounting device can also be used to attach ordinary legs in which front and rear columns are connected by upper and lower connecting plates or the like.
