Description

  The present invention relates to a structure of a wiring receiving apparatus that can be wired from above in a fixture used in an office space such as an office or a nurse station.

  In fixtures used in office spaces such as offices and nurse stations, wiring such as power lines and information lines may be routed from the ceiling in accordance with installation conditions such as the presence of a free access floor and the location of wiring facilities. In such a fixture, in order to ensure safety and to improve the appearance, the fixture and the ceiling are connected by a column extending upward, and the inside of a wiring duct arranged along the column is passed. The invention which is drawn is proposed (for example, patent document 1).

  According to the present invention, since it is possible to stably guide the wiring with the support columns, there is no possibility that the wiring is pulled or disconnected even when the user accidentally contacts the wiring. If the wiring is accommodated in a duct provided along the support column, not only can the user be prevented from touching the wiring directly, but also the appearance can be improved.

  However, according to this invention, since the fixture and the ceiling are connected, the installation position of the fixture is fixed. Therefore, when the installation position and orientation of the fixtures are changed due to the layout change, if the wiring extraction position changes from the ceiling, it cannot be dealt with and new construction is required. .

On the other hand, there has been proposed a structure in which a support column extending from the fixture to the vicinity of the ceiling is provided and a wiring receiver is provided at the upper end of the support column (for example, Patent Document 2). However, according to the present invention, the movement of the fixture and the change of the wiring take-out position can be dealt with within the allowable range of the wiring receiver, but there is a problem that it cannot be dealt with in other areas.
