Description

[Detailed Description of the Invention] This invention relates to a multi-lamp lighting fixture equipped with a reflecting plate having a large width dimension.

Conventionally, twist latches and screws have been used to attach thin, large-width reflectors to the main body of lighting equipment.

However, installing this reflector sometimes requires a certain amount of tightening force, so when the edges of the reflector and the device body are joined, the reflector tends to warp and deform, so care must be taken to prevent this deformation. This has the disadvantage that a gap is created between the reflector and the main body of the instrument.

That is, it is difficult to mount with good shape stability.

This invention was devised in view of these points, and the purpose is to obtain a multi-light lighting fixture that can be firmly attached without deforming even if a thin reflector is used. be.

This idea forms a bead that extends in the width direction on the reflector, which is located near the reflector mounting part, so even if the reflector is thin, its strength is reinforced and the same as that of a thick reflector. strength is generated, and even when the reflector is attached to the main body of the device under pressure, it will not warp, and the polymer pieces formed at the ends will be overlapped with the protrusions to further prevent deformation. The structure is such that the reflector can be firmly attached even if there is no gap between the reflector and the main body of the instrument.

An embodiment of this invention will be described based on the drawings.

First, the instrument main body 1 has end plates 2 at both ends thereof, and has a lower surface 3 opening downward.

Mounting metal fittings 4 are attached slightly inward from both ends of the instrument body 1.

Two fitting parts 6 into which the lamp sockets 5 are fitted are formed on the end plate 2 side of these fittings 4, and both sides of these fitting parts 6 are connected to the lamp sockets 5.
The lamp socket 5 is engaged with a retaining groove (not shown) of the lamp socket 5.
This is a holding piece 7 that holds the .

Further, a mounting hole 8 is formed in the mounting bracket 4, and is located inwardly between the fitting portions 6, that is, at an intermediate portion thereof, and serves as a reflection plate mounting portion.

This attachment hole 8 is elongated and extends in the longitudinal direction.

Further, two pairs of protrusions 9 are formed on both sides of this attachment (L8) to prevent rotation of the twist latch, which will be described later.

A protrusion 10 is integrally formed on the end plate 2 and protrudes inward so as to be located substantially on the same line as the attachment hole 8 in the longitudinal direction.

Note that a stabilizer 11 and other accessory parts are attached to the center of the instrument body 1.

Therefore, a reflector 12 having a length matching the length of the appliance body 1 is provided, and both ends of the reflector 11 have cutouts that fit into the lamp socket 5 attached to the appliance body 1. 13 are formed two by two, and these notches 1
An overlapping piece 14 that overlaps the protrusion 10 is formed between the three.

A T-shaped bead 15 is stamped at both ends of the reflector plate 12 and extends in the width direction of the reflector plate 12 and also extends to the center of the overlapping piece 14 to reinforce these parts. A through hole 16 is formed adjacent to 15 and aligned with the mounting hole 8.

Twist latch 1 that attaches the reflector plate 12 to the instrument main body 1 by inserting the distal end of the through hole 16 into the mounting hole 8 and rotating it by 90° in any direction.
7 is removably attached.

In such a configuration, in order to attach the reflector 12 to the appliance main body 1 to which the lamp socket 5 is attached, the lamp socket 5 is fitted into the notch 13 while the overlapping piece 14 is overlapped with the protrusion 10, and the lamp socket 5 is fitted into the notch 13. Reflector 12 on the bottom surface 3 of the main body 1
to join.

Then, the twist latch 1 is inserted into the mounting hole 8 through the through hole 16.
When the tip of 7 is inserted and the twist latch 17 is rotated 90 degrees, the tip is perpendicular to the attachment hole 8 and enters between the protrusions 9, preventing the twist latch 17 from returning.

In addition, the dimensional relationship of each part is set so that the reflection plate 12 can be pressed by this twist latch 17.
This pressing force allows the device to be firmly attached to the device main body 1.

However, due to the presence of the overlapping piece 14 and the T-shaped bead 15 formed in the width direction, the mounting portion of the reflector 12 is reinforced, and since the overlapping piece 14 overlaps the protrusion 10, the lower surface 3 Even if the reflector plate 12 and the reflector plate 12 are joined together, the reflector plate 12 is not deformed and is firmly attached to the reflector plate 12 on the instrument main body 1.

In particular, the overlapping piece 14 and bead 15 that overlap the protrusion 10
By forming these and locally increasing the strength, the material thickness of the reflecting plate 12 can be made thin, and by using a thin material for the reflecting plate 12 having a large width dimension, the material cost is reduced. Moreover, the weight can also be reduced.

In the above embodiment, the bead 15 was made into a T-shape and was formed up to the overlapping piece 14.
5 may be omitted and may be I-shaped only in the width direction.

Furthermore, although the question was asked about the use of the twist latch 17 as a fixture, a screw may be used instead of the twist latch 17.

Since this invention is constructed as described above, the strength of the reflective plate, which is necessarily large in width and low in strength when used for multiple lights, is reinforced by beads in the width direction, and the overlapping pieces have protrusions. By overlapping the reflector and preventing deformation when tightening and fixing, even a thin reflector can be firmly installed without creating a gap between it and the main body of the device, which also improves its appearance. It has the following effects:
