Since the top plate 1A is supported by the support, the support strength of the top plate 1A can be improved, and the lateral shaking of the top plate 1A can be suppressed. Furthermore, since the intermediate leg 31 is hollow and is provided at a position overlapping with the wiring opening 6, various cables raised from the floor surface F are not exposed, and the cables for wiring are passed through the interior of the intermediate leg 31. Wiring can be performed at the shortest distance directly below the opening 6. - 特許庁

In the third embodiment, the cable insertion hole 34a and the connecting bolt insertion hole 34b (see FIG. 6, etc.) of the intermediate leg 31 are preferably covered with a cap member or the like. Further, the intermediate leg 31 in the third embodiment may have a configuration in which the cable insertion holes 34a and the connecting bolt insertion holes 34b are not formed.

Further, in the third embodiment, it is possible to attach an intermediate leg 31A and a wire receiving member 55 (see FIGS. 8 to 10) instead of the intermediate leg 31. FIG.

Although the embodiments of the present invention have been described above, the materials, shapes, arrangements, numbers, etc. in the above embodiments are examples, and the present invention can be embodied in various other ways. For example, the shape of the top plate is not limited to rectangular or square, and may be circular, elliptical, L-shaped, trapezoidal, or the like.

Further, the planar shape of the intermediate leg is not limited to a substantially rectangular shape, and may be other polygonal shapes such as hexagons and trapezoids, or may be circular or elliptical.

Further, the table of the present invention is not limited to the configuration in which the intermediate leg and the wire receiving member use common screw holes. For example, the intermediate leg may be fixed to the bottom surface of the top plate using a dedicated screw hole provided on the bottom surface of the top plate. In addition, the intermediate leg is fixed to the lower surface of the top plate using a screw hole for fixing another member different from the wiring receiving member (for example, a member for attaching the desk panel as described above). good too.
