2. Description of the Related Art Conventionally, as a mounting structure for mounting legs on a desk top plate, for example, as shown in FIG.
A T-shaped standing piece e having an outer extending portion c extending to the end surface b1 side of the top plate b and an inner extending portion d extending to the opposite end surface side is fixed to the upper end surface of the In addition, the outer extending portion c is fixed to the rising surface or the lower surface of the crosspiece f of the top plate b with a bolt g, and the inward extending portion d is attached to the rising surface of the crosspiece f. It is known that the fastening means h and bolts i are used for fastening.

[0003]

However, in such a case, since the outwardly extending portion c of the standing piece e extends outwardly beyond the outer surface a1 of the leg a, the top plate b is It is necessary to overhang the portion near the end surface outward of the outer surface a1 of the leg a. For this reason, the leg a near the end face b1 of the top plate b
It is difficult to take a form that supports
There is a problem that the degree of freedom in design is limited.

In order to solve such a problem, for example, as shown in FIG. 8, an L-shape in which only the edge portion on the opposite side of the top plate end surface b1 is extended inward from the upper end surface of the leg a. It is conceivable that the standing piece k of FIG. 2 is projected and the extending portion m of the standing piece k is fixed to the standing surface of the crosspiece f provided on the lower surface of the top plate b by the bolt n. However, the bolt n is
Since there is a constraint that it must be provided at a position where a tool can be inserted, there is a problem that it is difficult to increase the mounting rigidity with only this because the distance between the fastening position by the bolt n and the leg a becomes large. Occurs.

[0005] An object of the present invention is to solve such a problem.

[0006]

In order to achieve the above object, the present invention takes the following measures. That is, the leg mounting structure in the furniture according to the present invention is a mounting structure for mounting the leg on the lower surface side of the end portion of the supported member such as a top plate, and the supported member has a crosspiece on the lower surface thereof. The portion is fixed to be close to the end surface of the supported member, and a protrusion is provided in the vicinity of the end surface of the upright surface of the crosspiece. Further, the leg is formed by projecting a standing piece on the upper end surface, and at the edge portion on the end surface side of the rising piece, an engaging concave portion that engages with the projection is formed, and the edge portion on the opposite end surface side is formed inside. I have been extended to. The engaging recess of the upright piece is engaged with the projection of the crosspiece so that the upper end surface of the leg comes into contact with or comes close to the lower surface of the supported member, and the inwardly extending portion of the upright piece. Is fastened to the crosspiece using a fastener.

A typical example of the fastening device is a bolt. In this case, it is preferable to provide a screw hole for screwing the bolt in the internal reinforcing member of the crosspiece.

In order to reduce the number of parts and simplify the structure, a tongue piece is integrally provided at the end of the internal reinforcing member,
It is desirable to form the protrusion by bending the tongue piece.

[0009]

With such a structure, the upright pieces provided on the legs have an L-shape extending only inward, so that the legs can be attached near the end surface of the supported member. Therefore, the degree of freedom in design can be improved. Moreover, in the present invention, not only the extending portion formed on the edge portion on the opposite end face side of the upright piece is fixed to the crosspiece member, but the engaging recessed portion provided on the edge portion on the end surface side of the upright piece is provided on the crosspiece member. Since the protrusions are engaged with the protrusions, it is possible to increase the coupling rigidity of the standing piece to the supported member without increasing the thickness of the material. Therefore, if the upright piece is firmly fixed to the leg by welding in advance, it is possible to obtain a highly rigid and sturdy mounting state, and securely attach the leg to the lower surface of the supported member so as not to wobble. You can wear it.
