Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a reflector fixing device for a lighting fixture, and more particularly to a fixing device for fixing a reflector to which a fixture body is fixed to a support frame that supports a shade.

For lighting fixtures in which the reflector to which the fixture body consisting of a lamp and its lighting fixture is fixed, and the support frame to which the shade is supported are constructed as separate members, a fixing device is required to fix both. .

Generally, in this type of lighting equipment, when the support frame is made of thin square timbers, the fixing device is fixed to the top surface of the support frame with wood screws, and the corner parts of the support frame are attached to improve strength and prevent deformation. , a holding frame is separately attached with wood screws or the like.

That is, in conventional lighting equipment, a holding frame and a fixing device are separately provided, and the number of parts is large, the structure is complicated, and the installation of these parts is troublesome.

Additionally, conventionally, when a fixing device has multiple mounting holes, such as a fixing hole and a locking hole, the position of the mounting hole is determined using a gauge or the like on the support frame and the drilling work is performed, so it is difficult to assemble. This requires a lot of effort.

This idea was created in view of the above points, and aims to provide a reflector fixing device for lighting equipment that reinforces the corners of the support frame that supports the shade and firmly fixes the reflector to the support frame. do.

This invention includes a mounting piece that is attached to the upper edge of a corner of a support frame that supports a shade on a step formed on the inner peripheral edge, a locking claw formed on the upper surface of this mounting piece, and an inner periphery of the corner. a fixed frame that is integrally formed with a receiving part on which the reflecting plate is placed and which supports the shade on its lower surface and which reinforces the corner of the supporting frame; and the fixed frame of the fixed frame. a fixing piece that is superimposed on the upper surface of the part and is provided so as to be able to be latched to the locking claw to fix the reflective plate; and the mounting piece is attached to the upper surface of the corner of the support frame, and the fixing piece is rotatable. and a supporting screw.

This invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 shows a lighting device implementing this invention, and FIG. 2 shows an embodiment of a reflector fixing device for a lighting device according to this invention.

In the figure, a support frame 2 made of wood, synthetic resin, metal, etc. is composed of an inner frame 4 and an outer frame 6, and a step 8 of the inner frame 4 is equipped with a reflector 10 and a reflector 12. be placed.

The reflecting plate 12 and the inner frame 4 are firmly fixed by a fixing device which will be described later.

A device main body 16 including a fluorescent lamp 14, a lighting device 15, etc. is arranged on the anti-sealing plate 12.

The lighting fixture configured in this manner is suspended from a power supply section (not shown) on the ceiling surface by a cord 20 pulled out from a cover 18 provided on the upper surface of the reflector plate 12.

In FIG. 2, the reflector fixing device 22 is connected to the support frame 2.
A fixed frame 28 is fixed to the upper edge of the corner of the inner frame 4 with main screws 24 and 26, and the wood screw 24 is fixed to the upper surface of this fixed frame 28.
and a fixing piece 30 which is rotatably fixed to the fixing member 30, and both are formed by pressing a metal plate.

That is, the fixed frame 28 is provided with standing walls 32 and 34 at right angles that abut against a step formed on the inner peripheral edge of the inner frame 4, and a right-angled isosceles triangle is formed between the lower edges of the standing walls 32 and 34. Uke is part 3
6 is integrally provided, and a trapezoidal mounting piece 38.40, which is attached to the upper edge of the inner frame 4, is provided on the upper edge of the vertical wall 32.34 to protrude in a right angle direction.

The mounting piece 38 has a mounting hole 42 through which the wood screw 24 is inserted.
The mounting piece 40 has a mounting hole 44 through which the wood screw 26 is inserted, and a locking pawl 46 that locks one end of the fixing piece 30.

In the case of this embodiment, the locking pawl 46 is formed by cutting and raising a part of the mounting piece 40 by press working.

Further, the fixing piece 30 is composed of a trapezoidal flat plate, and the fixing piece 30 has a mounting hole 4 through which the wood screw 24 is inserted.
8, a projecting piece 50 is provided by cutting and raising at a position engaging with the locking claw 46 of the fixed frame 28.

Further, a rib 52 is formed on the lower surface of the fixed piece 30 to press the upper surface of the reflection plate 12 placed on the fixed frame 28, and on one side of the fixed piece 30, a rib 52 is formed to press the upper surface of the reflection plate 12 placed on the fixed frame 28. For this purpose, a vertical wall 54 for operation is integrally erected, and FIG. 3 shows a cross section of the fixed piece 30 along the line III--III.

With the structure as described above, the reflector fixing device 22 has wooden screws 24.2 attached to the upper edge of the corner of the support frame 2, as shown in FIG.
6, it is firmly fixed.

The state shown in FIG. 4 is the state in which the fixing piece 30 is opened, and in this state, the reflecting plate 12 shown in FIG.

Then, as shown in FIG. 5, by rotating the fixing piece 30 counterclockwise toward the upper surface of the reflector 12 and engaging the locking claw 46 of the mounting piece 40, the reflector 12 can be attached to the fixing frame. It is fixed to the support frame 2 by being held between the fixing piece 28 and the fixing piece 30.

Note that the upper end edge of the shade 10 shown in FIG. It is held and fixed between the

According to the above configuration, the support frame 2 and the reflection plate 12 can be firmly fixed, and the fixed frame 28 is fixed by bringing its vertical walls 32 and 34 into contact with the inner side of the inner frame 4 of the support frame 2. Therefore, it is possible to improve the strength of the support frame 2 while forming it.

In particular, the ribs 52 of the fixed piece 30 are brought into contact with the upper surface of the reflecting plate 12, and work together with the elastic force of the fixed piece 30 to firmly hold the reflecting plate 12.

Furthermore, since the fixing device and the reinforcing means for the support frame 2, which were conventionally formed separately, are integrated, the fixing and reinforcing structure is simplified, making assembly easier, and improving workability.

Further, in the above embodiment, when fixing the fixing frame 28 and the fixing piece 30 to the support frame 2, wood screws are used because the support frame 2 is made of wood, but the support frame 2 is made of synthetic resin, metal, etc. If configured, the fixing frame 28 and the fixing piece 30 may be fixed by attaching bolts to the slotted holes formed on the support frame 2, or they may be fixed to the support frame 2 by other fixing means. Similar effects can be expected.

As explained above, according to the present invention, the fixing frame is fixed to the upper edge of the corner of the support frame on which the shade is placed, and the receiver of this fixing frame holds the shade against the support frame with the lower surface of the part. In addition to being able to firmly fix the reflector, the corners of the support frame can also be reinforced, making conventional reinforcing means unnecessary, simplifying the structure of the lighting fixture, and facilitating assembly. I can do it.
