Description

Description: TECHNICAL FIELD The present invention relates to a movable partition system that partitions a room by a partition panel by using a trolley duct as a track for moving the partition panel.

[Background technology]

Conventionally, in a place used by an unspecified number of people such as a hall in a conference hall or a banquet hall, the size of the room is adjusted using a movable partition panel in order to effectively use the space. That is, as shown in FIGS. 7 and 8, the ceiling of the room 1
A duct 2 made of metal having a continuous opening on the lower surface is attached to 1A along a partition boundary 3, a trolley (not shown) that can travel freely is accommodated in the duct 2, and a movable partition is provided through the opening of the duct 2 in the trolley. By suspending the panel 4 and moving the movable partition panel 4 in the direction of the arrow C along the duct 2, the room 1 is partitioned into two rooms A and B, for example.

In FIGS. 7 and 8, 1B is a wall, 1C is a floor, 5 is a doorway, and 6 is a movable partition panel storage section.

As described above, when partitioning a large room, it is often necessary to provide a power outlet, an antenna outlet for a television receiver, a microphone content, and the like for each of the divided small rooms.

However, power outlets, antenna outlets, microphone outlets, etc. are provided only on the wall of the room, and when power is supplied to the electrical equipment arranged in each small room, wiring from the outlet to the electrical equipment is performed. However, there are problems such as being too long to get in the way, and the cord of the electric device is too short to place the electric device at an appropriate position. This has been a particularly serious problem in a Japanese-style room where an outlet cannot be installed on the floor in advance.

Among them, along with the development of broadcasting culture in recent years, it is said that in addition to powering from the movable partition panel, it is desired to input and output television broadcasting signals, independent television broadcasting signals from video cameras and control signals for various devices from the partition panel. There is a request. That is, for example, as shown in FIG.
The television image is received by the television receiver 10 by inserting the connector 11 for inputting the high frequency signal of the television receiver 10 into the connector of the movable partition panel 9 suspended from the duct 8 attached to the ceiling of the room 7. There is a desire to do so. In FIG. 9, 12 is a movable partition panel storage section, and 13 is a power outlet.
