f and 13f are positioning projections that protrude from the base 11 or the stay 13 and fit into the inner periphery of the support column 12.

In this embodiment, when the stay 13 is integrally formed, connecting projections 14 are integrally formed inward from the rear end thereof, and these projections 14 are formed in a square pipe shape. The left and right ends of the connecting member 15 are fitted to each other to connect the left and right legs 1 in a gate shape. A groove 14a having a V-shaped cross section as shown in FIG. 7 is formed in the lower surface of the projection 14, and the inner surface of the bottom wall near the end of the corresponding connecting member 15 corresponds to the groove 14a. A ridge 15a is provided, and when the end of the connecting member 15 is fitted to the projection 14,
The grooves 14a and the ridges 15a are taperedly engaged.

In addition, behind the stay 13, FIG.
As shown in FIGS. 4 and 6, an aluminum die-cast support 3 for mounting optional members such as shelves is provided, and a wiring space S is provided between the support 3 and the stay 12.
Is formed. When attaching this support 3,
A mounting plate 31 having a nut 31a fixedly attached thereto is rigidly attached to the inner surface of the back wall 12y of the support 12, and supports the base 3a of the support 3 with the base end 3a attached to the back wall 12y of the support 12. A screw 33 is inserted into a hole 32 provided in a base end 3a of the body 3 and screwed to the nut 31a at a position penetrating the support 12 to apply a load acting on the support 3 to the support 12 which is a hollow rigid body. I try to support them.

In the above-described configuration, the present embodiment further includes, as shown in FIG. 2, stepped pins 13e for mounting the top plate at two positions on the rear end side of the top plate mounting surface 13a of the stay 13.

The rear end of the top plate 1 is firstly engaged with the stay 13 by inserting the stepped pin 13e attached to any of 3d2, and then the top plate 2 is slid forward and the screw holes 22 are inserted through the screw holes 22. The top plate 2 is attached to the leg 1 by screwing a screw (not shown) inserted through the screw insertion hole 13c from below the stay 13 into the screw hole 22 of the top plate 2 in a state where the top plate 2 matches the hole 13c1 or 13c2. Like that.

In this case, when the stepped pin 13e is attached to the hole 13d1 on the rear end side and the polishing hole 21 of the top plate 2 is engaged, the top plate 2 is attached to the regular mounting position shown in FIG. However, the stepped pin 13e can be
2, the top plate 2 can be mounted at a mounting position deviated to the front end side shown in FIG. 9 when the polishing holes 21 of the top plate 2 are engaged. For this reason, if the auxiliary top plate 2X is attached to the rear end 2a side of the top plate 2, the top plate surface can be effectively expanded.

As described above, the desk of the present embodiment does not require the outer panel, which has conventionally been indispensable as an element part constituting a part of the structure, as an essential component. It becomes unnecessary to strongly connect the stay 2 and the stay 1 with higher rigidity than necessary. For this reason, as shown in the figure, the outer panel can be removed to open the lower limb space widely, and a simple attachment / detachment structure can be adopted between the top plate 2 and the stay 13 to remove the top plate 2 only by attaching and detaching screws. Can be easily changed.

In this embodiment, the support 3 for mounting the option is disposed behind the stay 13, and the wiring space S is formed between the support 3 and the stay 13.
The high load acts on the support 12 via the support 3 as a large turning moment. In this embodiment, the support 12 is a hollow rigid body, and the mounting plate 31 is attached to the inner surface of the back wall 12y of the support 12.
Are rigidly connected to connect the base end 3a of the support 3, so that optional members such as shelves can be accurately supported via the support 3.

Further, the column 12 is composed of an outer bending member 16 and an inner bending member 17, and these two bending members 16, 17 are provided.
A hollow rigid body is formed by
Since the recesses 6 for wiring insertion are constituted by 6 and 17, it is possible to support the top plate load and the load of optional members such as shelves with effective strength without forming the column 12 by aluminum die casting or the like. Moreover, the recess 1 for inserting the wiring
The wiring that has been set up from the floor using the wiring space S
Therefore, the added value as a desk can be effectively increased.

The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, FIG.
The rear end 13y of the stay 13 is fitted into the column 12 which is a hollow rigid body as shown in FIG. 1 and attached to the inner surface of the back wall 12y. Can effectively support a shelf load or the like.

As shown in FIG. 11, the rear end 13y of the stay 13 is hung down along the outer surface of the back wall 12y of the column 12, and the support 3 is continuously formed on the rear end 13y by integral molding. Of course, it doesn't matter. Furthermore, it goes without saying that the present invention does not prevent the attachment of the outer panel or the inner panel or the strong connection of the top plate to the top plate receiving member.

That is, when the desk of the present invention supports the left and right top plate receiving members attached to the upper end of the support column with the lower surfaces of the left and right side edges attached thereto, each of the top plate receiving members is an integrally formed body. At the time of molding, a projection protruding toward the inner surface side is formed at the rear end thereof, and both projections are connected by a connection member having an end taperedly engaged with the corresponding projection. The left and right columns, the top plate receiving member and the connecting member constitute a portal-shaped structure as a whole.

For this reason, the outer panel and the top plate are not always indispensable as a part of the structure. When unnecessary, the outer panel can be removed to open the lower limb space widely, and the top plate and the top plate can be opened. By adopting a connection structure that can be easily attached and detached between the receiving members, the function as a desk can be effectively enhanced, for example, it is possible to respond to a request for changing the mounting position.
