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
2 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 square cross section are protruded, and a leg plate at the tip of the front mounting plate 5 is provided. The mounting plate 5 is provided with crosspieces 5a and 5a' as shown in FIG. It is fixed by a bolt 8 screwed into the hole 5', and a mounting protrusion 9 is cut and raised at the tip of the rear mounting plate 6, as shown in FIG.

In contrast, the front and rear reinforcing plates 10.1 provided on the back side of the top plate 1
Fitting holes 12 and 1 are provided in the vertical plate portions 1 facing each other, respectively.
3 are provided, and the mounting piece 7 and the projection 9 are respectively fitted and locked thereto.

(Figure 2).

In FIG. 2, 5'' is a mounting nut fixed to the peripheral edge of the mounting hole 5'.

Since the leg mounting device of the present invention has the above-mentioned structure, when assembling it, first place the top plate 1 upside down on the floor or a suitable table, then loosen the bolts 8 at the front of the legs and attach the mounting pieces 7 to the leg plate. Retract it to part 5a, and then attach the mounting plates 5 and 6 on the front and rear of the legs 3.
is fitted between the front and rear reinforcing plates 10 and 11 of the top plate 1, and the rear mounting protrusion 9 is fitted and locked into the rear fitting hole 13, and the front mounting piece 7 is moved to fit the front part. The leg 3 can be reliably attached to the top plate 1 by an extremely simple operation of fitting it into the hole 12, fixing it with the bolt 8, and locking it in the fitting hole 12. Since it is always attached to the mounting plate 5, there is no risk of it being lost during assembly, which is extremely advantageous for assembly work.

In this case, the step portions 5a and 5a' of the mounting plate 5 prevent the front portion of the leg 3 from shifting laterally due to rotation of the mounting piece 7.

The same effect can be obtained by providing each mounting mechanism using the mounting piece 7 and the protrusion 9 on either of the front or rear mounting plates 5, 6.

In FIG. 3, 14 is a headed locking pin provided at the base of the front mounting plate 5, and when attaching the legs, the head 14a is the sixth pin.
It is inserted through the insertion opening 15' on the lower surface of the hook-shaped locking hole 15 provided at the corresponding position of the front reinforcing plate 10 shown in the figure, and is locked to the side stop edge 15'' to further strengthen the installation. Make it.

In this case, the legs 3 can be easily attached to the top plate 1 with the legs 3 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 rotated from the inside to the outside using the attachment part with the axle box 2 as a fulcrum. If you move, the mounting protrusion 9 on the rear of the leg 3 will fit and be fixed in the rear fitting hole 13, so if you further rotate the front part of the leg 3 vertically around this point,
The head 14a of the locking pin of the front mounting plate 5 matches the locking hole 15, so after locking it there, the mounting piece 7 is inserted as described above.
FIG. 7 shows another example of the mounting protrusion 9, which can be fitted and locked into the front fitting hole 12, and other locking pins or the like may be fixed thereto.

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