Description

[Detailed Description of the Invention] A. Object of the Invention (1) Industrial Field of Application The present invention provides a floor wiring device, in particular, a duct body which is buried in the floor for storing wiring, and a cover is provided on the top of the duct body. It relates to a type in which the upper opening is attached so that it can be opened and closed.

(2) Conventional technology Conventionally, in such floor wiring devices, when connecting to the stored wiring, a wiring device body such as an outlet body is fixedly attached to the lid, or a wiring device body such as an outlet body is fixedly attached to the lid. Typically, the wiring is drawn out through the opening.

(3) Problems to be Solved by the Invention However, those using a fixed type outlet body protrude high upward from the lid even when not in use, which is not aesthetically pleasing. Furthermore, with devices that pull out wiring, when changing the connection position, etc., it is necessary to open the lid and connect the stored wiring, which is troublesome.

Therefore, in order to solve this problem, we developed a wiring device that has a plug socket on the side and can be retracted from the floor, but simply slides up and down relative to the duct body (for example, 56-96588) and one that is pivotally attached to the duct body so that it can tilt (for example, see Japanese Patent Application Laid-open No. 57-16511). However, since the plug socket is located on the vertical side of the device body, it is difficult to insert the plug, and if the effective area of the side surface is made wider, the device body in the usage position will be more difficult to insert. In addition, in the above-mentioned device, the side surface of the wiring device body on the plug insertion port side passes through the opening of the duct body due to rotational movement, so the side surface must be widened. When formed,
The opening of the duct main body must be made larger to that extent, which poses problems such as an increase in the size of the device as a whole.

An object of the present invention is to provide a floor wiring device with a simple structure that can solve all of the above problems.

B. Structure of the Invention (1) Means for Solving the Problems In order to achieve the above object, the present invention provides a structure in which a duct is installed in the upper part of the duct body buried in the floor to house the wiring.
In a floor wiring device in which a lid is attached to open and close an opening on the upper surface of the duct main body, the wiring equipment main body, the wiring equipment main body, its storage position in the duct main body, and the opening of the lid a guide mechanism that protrudes onto the duct body through the duct body and guides the wiring appliance so as to be movable between a use position tilted in a predetermined direction; The guide mechanism is fixed to the duct body and includes at least a common stopper provided on the duct body so as to be movable between a lock position where the wiring device can be engaged and a release position where the wiring device body is released. a guide member extending in the vertical direction; a support shaft portion that protrudes from the lower part of the wiring device main body and is fitted into the guide member so as to be able to move up and down; and an engaging portion that engages with the engaged portion of the duct body during the ascent and tilts the wiring device body in the predetermined direction around the support shaft portion as the support shaft portion continues to rise. The main body is characterized in that a plug insertion opening is formed on a side surface that faces diagonally upward when the main body is tilted in the predetermined direction.

(2) Function The wiring device body can be stored inside the duct body when not in use, and when in use, it should protrude above the lid opening of the duct body so that the plug insertion port is exposed above the floor surface. I can do it.

In particular, when the wiring device main body in the storage position is raised by raising the support shaft portion along the guide member, the engaging portion engages with the engaged portion during the rise and supports the wiring device main body. Since it can be forcibly tilted around the shaft in the above specified direction,
In the usage position of the wiring device main body, the side surface of the wiring device main body on the plug insertion port side can always face diagonally upward. Moreover, even if the side surface of the wiring device body on the plug insertion side is widened, the effective height is kept as low as possible due to the slope of the device body, and furthermore, even if the lid opening is made small, the side surface Even if it is widened, the upward movement of the instrument body along the guide member allows the side surface to pass through the lid opening without difficulty.
