Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a table having an outlet near the periphery of a top plate, and particularly to the table having a pipe supporting leg.

[0002]

[Prior art and its problems]

 When using OA equipment such as computer terminals and word processors, lighting equipment and other electrical products on the table, the plugs of these equipment have conventionally been pulled in through an outlet placed on the wall surface in the room or an extension cord. The power is secured by connecting it to the receptacle. For this reason, in the normal case, the power cord of the electric device hangs down from the top plate, which is very unsightly and may cause the power cord to be caught during passage.

Therefore, in a table or the like having a supporting leg using a channel material, a synthetic resin cover or the like along the longitudinal direction is attached to the channel material to form a vertical wiring duct, and a power cord of an electric device is connected to a floor portion through the duct. Some of them are also available. However, depending on the device, the power cord was short, and there were often restrictions on the wiring position of the device on the top plate due to the passage of the vertical wiring duct.

On the other hand, a table having a pipe supporting leg is the most widely used because it is structurally simple and versatile, and is easily manufactured and provided at a low cost. However, since the supporting leg is a pipe and does not have an open portion along the longitudinal direction unlike the above-mentioned channel material, conventionally, wiring through the inside of the supporting leg has not been realized.

[0005]

[Means for Solving the Problems]

 In view of the above-mentioned circumstances, the present invention provides a table in which the inside of the supporting leg can be used for wiring in a form having a pipe supporting leg and the wiring of an electric device on the top plate is hardly restricted. Is.

That is, according to the present invention, a corner metal fitting having an outlet mounting portion is fixed to a corner portion on the top surface of the top plate, and a fitting portion for a pipe of the support leg is fitted to a lower end of a pipe supporting leg connected to the corner metal fitting at an upper end portion. And an adjuster having a pipe end receiving portion integrally formed at a lower portion of the fitting portion, and a vertical groove for wiring provided on a peripheral surface extending from the fitting portion to the pipe end receiving portion. The gist is a table with an outlet configured such that the wiring from the outlet of the outlet mounting portion passes through the inside of the supporting leg and is led out through the vertical groove.

[0007]

[Action]

 When the fitting part of the adjuster is fitted into the pipe of the support leg from the lower end opening, the lower end of the vertical groove of the adjuster is opened to the outside because the lower end of the pipe is supported by the pipe end receiving part. The inside communicates with the part. Therefore, this vertical groove allows the wiring from the outlet to be introduced to the outside at the floor through the inside of the supporting leg. However, since the power can be secured from the outlet near the top plate, even electrical equipment with a short power cord is not restricted by the position of the top plate due to the length of the cord.
