BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to lighting equipment.

[0002]

2. Description of the Related Art FIGS. 9 and 10 show a first conventional example (for example, Japanese Utility Model Publication No. Sho 56-41291) relating to mounting of a reflector. That is, a notch 52 is formed in each of the opposing edges of the pair of cut-and-raised pieces 51 of the instrument body 50, a long hole 53 matching the notch 52 is formed in the reflecting plate 54, and the notch 5 is inserted through the long hole 53.
2 through the latch 55 to rotate the reflector 54 to the instrument body 5.
0, and the upper end of the reflection plate 54 is brought into close contact with the ceiling.
L is a closing margin.

FIG. 11 shows a second conventional example. That is,
A screw hole 56 is formed in the instrument body 50, a through hole 57 that matches the screw hole 56 is formed in the reflection plate 54, and a screw 58 is screwed into the screw hole 56 through the through hole 57 and tightened. 59
Is a lamp socket. FIG. 12 shows a third conventional example. That is, in this lighting fixture, the spring 60 is interposed between the fixture main body 50 and the reflection plate 54. Reference numeral 61 denotes a washer, and reference numerals 62 and 63 denote holes with slits which are locked by the insertion and rotation of the latch 55.

[0004]

In the first prior art, the interference L is provided between the reflector 54 and the instrument body 50 in order to bring the reflector 54 into close contact with the ceiling. It is necessary to rotate the latch 55 and fix the reflection plate 54 while pressing the reflection plate 54 in close contact with the ceiling. Therefore, there is a disadvantage that the operation is troublesome.

In the second conventional example, since the reflecting plate 54 is tightened with the screw 58, the screw 58 has to be rotated and fixed several times, which is time-consuming. The third conventional example has the disadvantage that the number of parts is large and the cost is high because the spring 60 and the like are required. Therefore, an object of the present invention is to provide a lighting fixture that can mount a reflector in a short time with a simple operation without increasing the number of parts.

[0006]

The lighting fixture of the present invention is:
An apparatus main body, a substantially T-shaped latch whose shaft is rotatably attached to the apparatus main body, and a reflecting plate having an elongated hole that is locked by inserting and rotating the head of the latch. A tapered surface for pressing an edge of the long hole toward the instrument body when the head is rotated is formed on the front side of the instrument body at the head of the latch. It is.

[0007]

According to the structure of the present invention, the long hole of the reflection plate is inserted into the head of the latch rotatably provided in the instrument body, and when the latch is rotated by 90 degrees, the tapered surface of the latch becomes the long hole. It rotates along the edge and presses the edge of the elongated hole against the instrument body. Therefore, the reflector can be attached in a short time with a simple operation without increasing the number of parts. Moreover, the structure is simple and inexpensive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. That is, this lighting fixture includes a fixture main body 1,
It has a latch 2 and a reflector 3. The apparatus main body 1 is for a straight tube fluorescent lamp directly attached to a ceiling, is formed in a rectangular flat plate having hanging pieces 4 on both sides, and a box-shaped mounting plate 5 is provided at both ends. Further, a lamp socket 6 and a latch 2 are provided on the mounting plate 5.

The latch 2 has a substantially T-shape, and a shaft 7 is rotatably attached to the instrument body 1. As shown in FIG. 2, the shaft 7 of the latch 2 of the embodiment penetrates through the mounting hole 14 of the mounting plate 5, and a flange 15 provided at an intermediate portion of the shaft 7 contacts the front surface 9 of the mounting plate 5. An attachment portion 16 is provided at an end of the portion 8 so as to be rotatably retained. The head 8 has an arcuate shape and the outside of the central portion is integrally attached to the shaft portion 7. A locking flat portion 17 is formed at a portion of the head 8 connected to the shaft portion 7, and the tapered surface 10 is formed between the locking flat portion 17 and both ends of the head 7. The axial dimension of the tapered surface 10 of the head 8 is substantially equal to or larger than the interference dimension L of the reflection plate 3.

The reflector 3 has a long hole 12 which is locked by inserting the head 8 of the latch 2 and rotating the head. And
Due to the tapered surface 10 formed on the front surface 9 side of the instrument body 1 at the head 8 of the latch 2, the slot 1
The second edge 11 is pushed up to the instrument body 1 side. The reflecting plate 3 of the embodiment is bent in an inverted trapezoidal cross section, and covers the entire instrument body 1. Reference numeral 13 denotes an insertion hole for the lamp socket 6.

According to this embodiment, the long hole 12 of the reflecting plate 3 is provided on the head 8 of the latch 2 rotatably provided on the instrument body 1.
When the latch 2 is rotated by 90 degrees, the tapered surface 10 of the latch 2 rotates along the edge 11 of the long hole 12 and presses the edge 11 of the long hole 12 against the instrument body 1. And
The reflecting plate 2 is locked by the locking flat portion 17, and the reflecting plate 2 is attached by absorbing the interference for bringing the upper edge of the reflecting plate 2 into close contact with a ceiling (not shown).

Therefore, the reflector 2 can be mounted in a short time by a simple operation without increasing the number of parts.
Moreover, the structure is simple and inexpensive. FIG. 5 shows a second embodiment of the present invention. That is, this lighting fixture is
Are molded simultaneously with the mounting plate 5 of the instrument body 1 with resin. In this case, a convex portion 18 for positioning is formed on the mounting plate 5, and a concave portion 19 which engages with the convex portion 18 on the collar 15 of the latch 2.
Is formed. Others are the same as the first embodiment.

According to this embodiment, the rotational position of the latch 2 becomes clear, and the latch 2 does not come off accidentally, so that a reliable mounting state of the reflector 3 can be ensured. A third embodiment of the present invention is shown in FIGS.
That is, in this lighting fixture, the cross section of the shaft portion 7 on the side opposite to the head 8 of the collar 15 of the latch 2 has an oval shape. In addition, a slit 20 having a width dimension that allows the narrow portion of the shaft portion 7 to pass but not the wide portion is formed between the mounting hole 14 of the mounting plate 5 and the edge of the mounting plate 5. Others are the same as the first embodiment.

According to this embodiment, the latch 2 can be easily inserted into the mounting hole 14, and can be prevented from being easily removed by turning.

[0015]

According to the lighting fixture of the present invention, the fixture main body and the substantially T-shape in which the shaft is rotatably attached to the fixture main body.
And a reflector having an elongated hole that is locked by inserting and rotating the head of the latch, and when the head is rotated, the edge of the elongated hole is used as the device. Since the tapered surface for pressing against the main body is formed on the front side of the instrument main body at the head of the latch, the reflector can be attached in a short time with a simple operation without increasing the number of parts. Moreover, there is an effect that the structure is simple and inexpensive.
