Description

  The present invention relates to a table used in an office or the like, a wiring cover device that closes a wiring space formed by a wiring duct or the like provided on a top plate of a fixture such as a desk, and a table including this device.

  Conventionally, in a desk, a table, etc. used in an office or the like, an electronic device is often placed on a top board and used. For this reason, it is necessary to treat the wiring lines such as communication lines and power supply lines of electronic devices used on the top board.

  As a conventional wiring processing structure, a wiring space is formed by forming an insertion hole for wiring on a part of the top plate of the fixture, or by providing a concave groove extending in the left-right direction at the rear edge of the top plate. The upper surface of the wiring cover is closed with a wiring cover (see, for example, Patent Documents 1 to 3), or the wiring cover can be rotated around a pivot provided at the left and right ends to improve workability during wiring. (For example, refer to Patent Document 4).

However, those described in Patent Documents 1 to 3 are not necessarily sufficient in strength because the wiring cover is formed of a synthetic resin or the like, or is formed of a soft member for securing a part of the wiring cover as a wire opening. Otherwise, the flatness of the top surface of the top plate may be impaired.
In addition, in the device described in Patent Document 4, when the wiring cover is opened, a part of the wiring cover closes the opening of the wiring space, so that a wide opening of the wiring space cannot be secured. In addition to the improvement of the above, there is a problem that the attachment / detachment structure and the opening / closing structure of the wiring cover become complicated in order to realize a desired cover rotating operation while supporting the wiring cover.
Japanese Patent No. 2683999 JP 2001-104083 A JP 2000-287758 A JP 2003-235649 A

  The present invention has been made in view of the above-described problems, and can easily handle the wiring of electronic devices used on the top board, and can easily and easily open and close and remove the wiring cover. It is an object of the present invention to provide a wiring cover device capable of improving the wiring work and eliminating the loss of the wiring cover, and a table provided with the device.

According to the present invention, the above problem is solved as follows.
(1) In the wiring cover device in which the opening of the wiring space that opens upward in the left-right direction along the rear edge of the top plate of the fixture is opened and closed with a removable wiring cover, wiring is made on the upper surface. A plurality of support members formed with a cover placement surface on which the cover can be placed are arranged in the wiring space so as to be separated from each other in the left-right direction, and the upper surface of the wiring cover and the upper surface of the top plate are substantially parallel by the support member. The wiring cover is held so as to be in a state, and a cover housing space is formed between the front end surface of the support member and the rear end surface of the top plate facing the supporting member, and the wiring cover is formed in the cover housing space. Can be placed and held in an upright position.

(2) In the above item (1), an inclined surface that is inclined downward toward the front is formed between the cover mounting surface and the front end surface of the support member, and the back surface of the wiring cover is slid on the inclined surface. Then, the wiring cover is guided toward the cover housing space so that the wiring cover is turned up and rotated upward and is in an upright state.

(3) In the above item (1) or (2), the horizontal support piece is formed from the lower end of the front end surface of the support member toward the rear end surface of the top plate facing the support member.
