However, in the table disclosed in Patent Document 1, there is a problem that the larger the top plate is, the greater the distance from the user to the connector becomes, and the work of sending the wiring becomes difficult.
In addition, the tables disclosed in Patent Documents 2 and 3 have a problem that it is difficult to apply them to a large-sized table because the arrangement position of the connector is limited to the upper part of the leg. For this reason, it is possible to increase the number of legs, but this increases the manufacturing cost and increases the number of parts that come into contact with the user's feet.
Furthermore, in the table disclosed in Patent Document 4, the edge member becomes extremely large in two directions, the height direction and the depth direction. For this reason, there is a problem that the load due to the insertion / removal work of the outlet or the like largely acts as a moment in the direction in which the connector falls off.

  The present invention has been made in view of such a problem, and even when the top plate is increased in size, it is close to the user's hand and at any position in the longitudinal direction of the top plate. An object of the present invention is to provide a furniture system in which a connector can be firmly arranged.

In order to solve the above problems, the present invention proposes the following means.
The furniture system according to the present invention comprises a leg that stands up on an installation surface and has a first wiring space formed therein for passing an electric wire therein, and a leg that is supported by the leg and extends horizontally. An intermediate structure that forms a second wiring space that passes through, a top plate that is supported by the intermediate structure, and a side surface of the intermediate structure that is connected to the electrical wiring and receives supply of electricity. and connectors formed on the intermediate structure, and a connecting portion connecting said legs and said connector at an arbitrary position along the longitudinal direction, the intermediate structure, extending in the longitudinal direction of the top plate In addition, a pair of rods facing each other in a direction intersecting the longitudinal direction is provided, the connecting portion is formed on side surfaces of the rods that face each other, and the connector has a third line through which the electrical wiring passes. To form a wiring space Comprising a member, the mounting member, said longitudinally from seeing the enveloping said杆材from below is formed in a substantially U-shape straddling the杆材, to be supported on the side surface of the杆材 Characterize.
