JP, 2016-86914, A

However, since the top plate moves up and down, the outlet provided at a predetermined location for the user is not always located at a position where it is easy to use. Of course, it is conceivable to provide a moving mechanism that allows the mounting position of the outlet to be moved. However, with such a configuration, the user has to perform a complicated operation of adjusting the moving mechanism each time the furniture with a ceiling plate is used. Will be forced.

That is, under the present circumstances, there is a demand for furniture with a ceiling plate in which the outlet is always located at a position that is easily handled by the user regardless of the height position of the ceiling plate.

An object of the present invention is to solve the above problems, and when using a furniture with a top plate capable of moving the top plate up and down, the user can effectively use the outlet regardless of the position of the top plate up and down. The purpose is to provide furniture with a top plate.

The present invention takes the following means in order to achieve such an object.

That is, the furniture with a ceiling plate according to the present invention includes a ceiling plate having an opening on the upper surface side, legs for supporting the ceiling plate so that the ceiling plate can be moved up and down from below, and a first outlet exposed on the upper surface side of the ceiling plate, A furniture with a ceiling plate comprising a second outlet facing outward in the vicinity of an edge on the lower surface side of the ceiling plate, wherein the first outlet and the second outlet are provided for lifting and lowering the ceiling plate. It is characterized in that a wiring extra length corresponding to the movable range is provided.

Here, the “outlet” is not limited to a power outlet for supplying electric power to an electric appliance, and is a concept including an information outlet such as a LAN cable or a telephone line for transferring information.

With such a configuration, when the height position of the tabletop is set low, the user can preferably use the first outlet exposed on the top surface side of the tabletop, and the height position of the tabletop can be adjusted. When it is set high, the second outlet becomes easier to access when it becomes difficult for the user to access the first outlet. In addition, since these outlets are connected to the outside in a state corresponding to the range of motion associated with the ascending/descending operation of the top plate, the wiring is not unnaturally pulled as the top plate is lifted. That is, according to the present invention, it is possible to provide furniture with a ceiling plate that allows a user to effectively use an outlet regardless of the position where the ceiling plate is raised or lowered.

In order to allow the top plate to be used more preferably, the first outlet is provided with an accessible state where it is exposed from the opening to the outside and a non-access state where it is housed in the opening and cannot be accessed from the outside. It is desirable to be able to operate between.

As a configuration of the first outlet that is easier for the user to use, there is a configuration in which the outlet faces obliquely upward toward the outside in an accessible state.

In order to effectively prevent the wirings connected to the first outlet and the second outlet from interfering with each other, a wiring duct disposed at a position facing the opening on the lower surface side of the top plate. And a vertical sorting mechanism for vertically partitioning the wiring duct into an upper accommodation space for accommodating the upper wiring connected to the first outlet and a lower accommodation space for accommodating the lower wiring connected to the second outlet. It is desirable to have

As a concrete structure for arranging the wiring so as not to be conspicuous from the outside, the wiring duct was attached to the lower surface side of the top plate so as to intersect with a part of the beam material interposed between the legs. As an alternative, a configuration in which substantially all of the wiring extending from the wiring duct and connected to the second outlet is arranged inside the beam material can be given.

In order to make the wiring accommodated in the wiring duct more inconspicuous from the outside, the wiring duct should be accommodated with the ceiling plate lifting wiring that is connected to the legs to raise and lower the ceiling plate and extended from the wiring duct. It suffices to arrange almost all of the wiring for raising and lowering the ceiling plate to be placed inside the beam member.
