Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor wiring storage device, and more particularly to a high-power passage for passing a power line in a duct body having a substantially U-shaped cross section which is arranged on the floor and whose open upper surface is opened and closed by a lid. The present invention relates to a line and / or a line that defines a weak electric line for passing a telephone line or a signal line.

[0002]

2. Description of the Related Art Conventionally, in such a device, an outlet box containing an outlet such as a movable outlet has been installed by specially projecting a box body on both widthwise outer sides of a duct body. With such a structure, the installation positions of the outlet boxes, and eventually the connection positions of the outlets, will be scattered in dots on the floor surface, which will not be able to respond appropriately to future expansion and movement of connected equipment, and also during construction. There was a problem such as poor workability.

In order to solve such a problem, for example, a duct and a connecting line having a substantially U-shaped cross section, which are adjacent to each other with a partition wall extending in the longitudinal direction therebetween, are defined in the duct body, and the partition wall has the partition wall. A plurality of wire transfer holes are bored at intervals in the longitudinal direction of the duct body, and at arbitrary positions in the connection line,
An outlet to which an electric wire extended from the inside of the connecting line to the inside of the connecting line through the electric wire transfer hole close to that position is connected, and an opening for exposing the upper surface of the outlet to the room,
A floor wiring storage device in which an opening / closing lid of a duct body is formed has already been proposed (see, for example, Japanese Patent Publication No. 3-59652), and in this proposal, a connection position by an outlet can be arbitrarily set on a connection line in the duct body. In addition to the advantage that the outlet can be set to the position, the installation work of the outlet can be easily performed with the opening / closing lid of the duct main body being opened and the inside of the connection line and the communication line being open to the outside.

[0004]

However, according to the above-mentioned proposal, since the connecting line adjacent to the through line is open in the duct main body over its entire length, it is connected to one end of the duct main body in the longitudinal direction. A power line or the like may be mistakenly drawn out from the crossing device into the connection line, and the power line or the like to be connected to the outlet may be connected to the outlet fixed on the connection line. Since wiring can be done from either direction on the other side, depending on the direction, the wiring can pass under the outlet, causing damage to the wire coating at the edge of the outlet, etc. or smooth outlet / retract operation of the outlet. May cause problems such as being blocked by the wires below.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a floor wiring storage device which can solve the problems of the conventional device.

[0006]

In order to achieve the above object, the present invention provides a duct main body having a substantially U-shaped cross section, which is arranged on the floor and whose open upper surface is opened and closed by a lid, in the longitudinal direction of the duct main body. A connecting line and a substantially U-shaped cross section that are adjacent to each other with a partition wall extending in between, and a plurality of wire transfer holes are formed in the partition wall at intervals in the duct main body longitudinal direction,
An outlet to which an electric wire extended from the inside of the through line to the inside of the connecting line is connected is attached to the inside of the connecting line, and an opening is formed in the lid to expose the upper surface of the outlet to the room. In the floor wiring storage device provided, a plurality of stopper plates that cross the inside of the connection line and partition the inside of the connection line into a plurality of outlet boxes, and are provided between each stopper plate and the inner wall of the connection line. A first feature is that each stopper plate is fixed to a connection line so that its position can be adjusted in the longitudinal direction, and the outlet is installed in at least one of the plurality of outlet boxes. In addition to the characteristics, the second characteristic is that the open end portion in the longitudinal direction of the connection line is closed by one of the plurality of stopper plates.

[0007]

[Operation] According to the above configuration, the inside of the connection line is divided into a plurality of outlet boxes arranged in the longitudinal direction of the connection line by the plurality of stopper plates that are fixed at arbitrary positions in the connection line. Since the facility positions of the outlets can be clearly divided in advance in the connection line, the facility work of the outlets can be easily performed based on the division. Depending on the selected position of the stopper plate, the wiring direction of the electric wire with respect to the outlet fixed in the connection line can be restricted to one direction along the connection line. This prevents the electric wire from accidentally passing under the outlet.

Further, if some of the stopper plates close the open end of the connecting line in the longitudinal direction, the electric wire is accidentally drawn into the connecting line from the crossing device connected to one longitudinal end of the duct body. There is no such incorrect wiring.

If the fixed position of the stopper plate Cs is selected closer to the end of the movable outlet C on the side farther from the terminal block 26 (on the right side in FIG. 1) as shown in the figure, the end of the movable plate C will be more than that end. Since wiring to the outlet C is physically impossible through the transfer hole h located on the outer side (right side in FIG. 1), the wiring is movable box 18 of the movable outlet C.
There is no risk of being guided to the terminal block 26 side through directly below,
Therefore, there is no problem that the coating of the electric wire is damaged at the lower end edge of the movable box 18 or that the smooth movement of the movable box 18 is hindered by the wiring below.

Further, a part of the stopper plates Cs is connected to each connection line L.
Since the open ends of c ₁ and Lc ₂ in the longitudinal direction are closed, an error such that an electric wire is mistakenly drawn into the connection lines Lc ₁ and Lc ₂ from the crossing device CR connected to the open ends. Wiring can be reliably prevented by the stopper plate Cs.

[0032]

As described above, according to the present invention, the inside of the connection line is divided into a plurality of outlet boxes by the plurality of stopper plates which are fixed at arbitrary positions in the connection line, and the inside of the outlet box is divided. Since the outlet can be installed, the facility position of the outlet can be clearly divided in advance in the linearly extending connection line, which is convenient for performing the facility work of the outlet. Depending on the selected position of the stopper plate, the wiring direction of the electric wire with respect to the outlet fixed in the connection line can be restricted to one direction along the connection line, so that the wiring work of the electric wire to the outlet is always in the proper direction. It can be done more accurately.

Further, if some of the stopper plates close the open end of the connecting line in the longitudinal direction, the electric wire is accidentally drawn into the connecting line from the crossing device connected to one end of the duct body in the longitudinal direction. It is possible to prevent such miswiring.
