Abstract

PROBLEM TO BE SOLVED: To make it difficult to cause floating or horizontal slippage of a plate by adding a fixing metal fitting for preventing the vertical and horizontal movement of the plate by use of the structure of a T-bar. SOLUTION: This fixing device comprises plate 5 and a fixing metal fitting 1 as basic elements. The fixing metal fitting 1 is rotatable, and a fixing screw 2 is attached thereto. The plate 5 is put into a T-bar 8 in the state where the fixing metal fitting 1 is vertically set. Thereafter, the fixing metal fitting 1 is rotated 90 deg. and horizontally set, and hooked under the top part of the T-bar 8. The fixing screw 2 is fastened in this state. Accordingly, the plate 5 can be prevented from being caught b a cable connected to the installation plate 5 and floated from the T-bar 8. The horizontal slip of the installation plate 5 can be also prevented by firmly fastening the fixing screw 2. Further, the fixing metal fitting 1 prevents falling of the plate 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for fixing an equipment plate for a system ceiling.

[0002]

2. Description of the Related Art A usual system ceiling equipment plate is:
Simply drop it on the T-bar. For this reason, if it gets caught on the cable, it easily lifts up, and lateral displacement occurs.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide an equipment plate fixing device for a system ceiling, which is unlikely to be lifted up or laterally shifted.

[0004]

According to the present invention, a fixture for preventing the equipment plate from moving in the vertical and horizontal directions by using the structure of the T-bar is added. The ends of the side plates on both sides of the U-shaped bracket are bent outward by 90 °, and the horizontal part is hooked from below on the top of the upper end of the T bar in the mounted state,
The fixing screw provided on the upper part of the fixing bracket is tightened, and the socket mounting bracket connected to the equipment plate by welding is pressed downward from above. At this time, since the fixing fitting is restrained from moving upward by the top of the T-bar, the fixing screw presses the equipment plate downward.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The basic elements are the equipment plate 5 and the fixture 1. The equipment plate 5, the socket mount 3, the socket 4, the light source (incandescent lamp) 7, and the reflector 6 are attached. The fixing bracket 1 is rotatable and has a fixing screw 2 attached thereto. As shown in FIG. 4 (a), the equipment plate 5 is dropped into the T-bar 8 with the fixture 1 in the vertical position. Thereafter, the fixing bracket 1 is rotated 90 ° so as to be turned sideways as shown in FIG. 3B, and hooked under the top of the T-bar 8. In this state, the fixing screw 2 is tightened. Fixing screw 2 is equipment plate 5
Floating or lateral displacement is prevented.

[0006]

According to the present invention, it is possible to prevent a cable or the like connected to an equipment plate from catching on a cable or the like and rising from the T-bar. Further, by firmly tightening the fixing screw, the lateral displacement of the equipment plate can be prevented. Furthermore, the fixture has the function of preventing the equipment plate from falling.
