Description

DETAILED DESCRIPTION OF THE INVENTION In general, in a modular system ceiling, it is almost impossible to suspend hanging objects such as lighting equipment or display boards from areas other than the installed lighting duct.
This is inconvenient in stores where the layout changes frequently.

In view of the above, the present invention provides a system in which a plurality of lighting ducts each having flanges on both inner edges of an opening and housing and fixing a pair of conductors are installed at a required interval, at least among adjacent lighting ducts in a ceiling. At an arbitrary position on either side, an operating rod having a protruding blade a and a hook piece is rotatably protruded from the upper surface of one end, and a plug blade is provided on both sides of the other end to be electrically connected to the blade a. A fit-in base with a fixing member arranged on the lower surface of the edge of the pipe is removably attached and fixed, and one end of a cross-writing duct, which has flanges at both ends of the opening on the side of the fixing member and accommodates and fixes a pair of conductors, is attached. An end base that is inserted and connected to the plug blade by bringing the conductor into contact therewith, and has an operating rod having a hook piece at the other end of the cross writing duct rotatably protruding from the upper surface of one end and a fixing member disposed on the lower surface of the other end. The operating rod of the end base is removably attached and fixed to the position corresponding to the phyto-in base of the other lighting duct by inserting and connecting the fixed member side of the phyto-in base, and a cross lighting duct is formed between the phyto-in base and the end base facing each other. The cross-lighting duct is cross-linked and fixed, and a lighting fixture or hanging object is detachably attached and suspended from the cross lighting duct, so that the lighting fixture or hanging object can be hung from any location on the ceiling.

The present invention will be explained below based on the embodiments shown in the drawings.
A plug blade is provided on both sides of the other end of the insulating body 4 so as to be rotatably protruded from the upper surface of one end, and is electrically connected to the plug blade a by rotating the operating rod 3 by 90 degrees. It is a fit-in base in which a fixing member d having a screw punch 5 is disposed on the lower surface of the rim, and a rotary lever 6 for rotating the operating rod 3 is protruded from the side surface of the insulating body 4 so that it can be operated from the outside. .

This phyto-in base A is connected to the lighting duct B to take out electricity, and serves as a so-called plug.

Note that 1o and io' are holding cylinders in which the screw punches 5 and 5' of the fixing members d and d' move up and down.

A' is an L-shaped base with a hook piece 2 attached upward at one end of the base 7'.
A box 8 having a rotatably provided operating rod 3' is disposed along the side piece 9, and a fixing member d' having a screw punch 5' is disposed on the lower surface of the other end. A locking lever 6 is provided on the side piece 9 so that the operating rod 3' can be locked and rotated from the outside.
' is provided protrudingly.

B is a lighting duct in which a pair of conductors e, e partially exposed and buried in an insulating sheath 14 are housed and fixed in a gutter-like duct 13 having flanges 12 and 12 on both sides of the opening 11, and is fixed to the ceiling base C. A plurality of hanging bolts 15 are fixed at one end, and a plurality of them are hung at required intervals, and a ceiling material 17 is engaged and placed between the edges 16 of the adjacent lighting ducts B, 16 to form a system ceiling. Configure.

Insert the above-mentioned phyto-in base A into any one of the lighting ducts B and B adjacent to each other on the ceiling of this system by inserting the plug blade a of the operating rod 3 and the hook piece 2 through the opening 11 and fixing it at an arbitrary location. The rotating lever 6 is rotated 900 degrees, the plug blade a is brought into contact with the conductor e, and the hook piece 2 is attached to the flange 12.
12, and has an opening 180 on the fixing member d side and flanges 19° 19 on both edges.
A pair of conductors e' in 0.

One end of the cross-writing duct G housing and fixing e' is inserted, and the conductors e' and e' are connected by contacting the plug blades, and the other end of the cross-writing duct is connected to the fixed part d of the end base A'. ' side is inserted and connected, and the operating rod 3' of the end base is inserted into the opening 1 of the other riding duct B.
1, rotate the rotary lever 6' by 90 degrees at the point where it faces the phyto-in base A, hook the hook piece 2' to the flange 12.12, and attach and fix it to the opposing phyto-in base A. A cross-lighting duct G is bridged to the end base A and fixed by fixing members d and d', and a lighting fixture E having a plug with a plug (not shown) is connected to the cross-lighting duct G with a conductor e'. +e' and is detachably attached and suspended, and a hanging object F such as a decorative board or display board is detachably locked to the flange 19 and suspended.

Since the present invention has the above-mentioned configuration, power can be supplied to the ceiling other than where the lighting duct is installed, without being limited to the module method. This has the effect of allowing you to freely respond to changes in the layout by allowing hanging objects to be hung on the wall.
