2. Description of the Related Art In FIG. 8 showing a conventional example, reference numeral 1 denotes a reflector of a ceiling-mounted lighting fixture. The reflecting plate 1 is made of a metal plate, and is provided with diagonal side plates 3 on both side edges of the top plate 2, and an end plate 4 is provided only at one longitudinal end of the top plate 2. Is open at the other end in the longitudinal direction.

The edge of the side plate 3 located on the opening side opposite to the top plate 2 of the reflection plate 1 forms a frame forming flange portion 3a having an L-shaped cross section, and is similarly located on the opening side. The edge of the end plate 4 is the frame forming flange portion 3a.
, A frame-forming flange portion 4a having an L-shaped cross section connected to the end on the side of the end plate 4 is formed. These frame forming flange portions 3a,
Reference numeral 4a denotes a ceiling surface on which the device is embedded and attached, which is applied from the lower surface thereof.

As shown in FIG. 10, two reflectors 1 each having one open end in the longitudinal direction are used and attached to the ceiling with their open ends together as shown in FIG. The frame-forming flange portions 3a, 3a of 1, 1 are connected to each other and partitioned between the reflection plates 1, 1, that is, the end plates 4 can be combined in a state where there is no partition corresponding to the back-to-back configuration. Therefore, it is possible to improve the appearance of the pair of lighting fixtures connected in a straight line.

In FIG. 10, reference numeral 5 denotes a lamp socket provided through cutout grooves provided at both ends in the longitudinal direction of the top plate 2, and reference numeral 6 denotes both ends supported by the lamp sockets 5 opposed to each other in the longitudinal direction of the reflector 1. Is a straight tube fluorescent lamp.

Meanwhile, the reflecting plate 1 used as described above uses a pair of cushioning members 7a and 7b having a rectangular tubular shape and a corrugated cardboard packaging plate 8 as shown in FIG. It was individually packaged.

The packaging plate 8 has side plates 10 connected to both sides of the bottom plate 9, an upper plate 11 connected to these side plates 10, and end plates 12 connected to both longitudinal ends of the bottom plate 9.
Two tongue pieces 13 are connected to both ends of each of the two. Note that reference numerals 14 in the developed view of the packaging plate 8 shown in FIG. 9 are all folding lines.

One of the shock absorbers 7a is disposed at one longitudinal end of the bottom plate 9 of the packaging plate 8 with its inner side surface 7a1 abutting the frame forming flange portion 4a, and the other shock absorber 7b has its inner side surface 7b1. It is arranged at the other end in the longitudinal direction of the bottom plate 9 against the open other end surface of the reflector 1, and thereby buffers the reflector 1 in the longitudinal direction. The tongue piece 13 bent from the end plate 12 superposed on the outer side surface of each of the shock absorbers 7a and 7b forms a frame forming flange portion 3a of the reflection plate 1.
The reflecting plate 1 is floated from the bottom plate 9 while supporting both ends in the longitudinal direction. Also, the side plate 10 and the upper plate 1 of the packaging plate 8
Numerals 1 are bent so as to surround the reflecting plate 1, respectively, and an adhesive tape (not shown) is stuck over the upper plate 11 which is joined to each other. That is, conventionally, the reflection plates 1 are individually packaged as described above.

[0009]

Therefore, conventionally, there are many packaging materials for one reflection plate 1 and the packaging cost is high, and the packaging volume for one reflection plate 1 is large and the transportation cost is high. There is.

In order to solve this problem, the present inventor has attempted to package a plurality of reflectors 1 in a conventional structure. However, since there was no suitable cushioning member for buffering the stacked reflectors, the reflection surface of the reflector located on the lower side of the vertically adjacent reflectors was not provided inside the lower reflector. The upper reflector is scratched by being rubbed with the upper reflector, which is overlapped with the upper reflector, and is exposed in parallel with the ceiling surface when the upper reflector is attached to the ceiling by the end faces of the frame constituting flanges 3a and 4a. It was found that the frame-constituting flange portions 3a and 4a of the lower reflector were easily damaged. In addition, a corner portion of the upper reflector between the end plate 4 and the top plate 2 where the strength is large may hit the end plate 4 of the lower reflector, and the end plate 4 may be deformed by an impact at that time. I also understood.

SUMMARY OF THE INVENTION An object of the present invention is to provide a luminaire in which a plurality of reflectors whose end plates are provided only at one end in the longitudinal direction can be stacked and packaged while preventing the reflectors to be overlapped from being damaged or deformed. The object of the present invention is to obtain a buffer for a reflection plate for use.

[0012]

According to the present invention, a side plate having an L-shaped frame forming flange portion is provided on both side edges of a top plate, and an L-shaped cross section connected to the frame forming flange portion is provided. An end plate having a frame-shaped flange portion is provided only at one longitudinal end of the top plate, and a plurality of reflectors for lighting fixtures with the other longitudinal end of the top plate being opened are stacked and packaged. A cushioning member made of a corrugated cardboard which is used by being arranged between the adjacent reflection plates, wherein the top plate is arranged between the top plates of the adjacent reflection plates in order to achieve the object. At one end of the buffer base portion, an end plate buffer portion that can be arranged and sandwiched between the end plates of the adjacent reflectors is connected to the top plate buffer base portion in a bendable manner, and a side plate of the adjacent reflector plate is provided. The side plate buffer part that is arranged between
The top plate buffer base is connected to both side edges of the top plate buffer base so as to be bendable with respect to the top plate buffer base.

[0013]

In the above-mentioned structure of the buffer, the end plate buffering portion disposed between the end plates of the adjacent reflectors prevents the end plates from coming into contact with each other and is located above the adjacent reflectors. A corner portion formed by the end plate and the top plate of the reflecting plate to be used absorbs an impact applied to the end plate of the reflecting plate located below.

Further, the top plate buffer base portion disposed between the top plates of the adjacent reflection plates prevents contact between the top plates and buffers between the top plates, in particular, on the upper side of the adjacent reflection plates. A corner formed by the end plate and the top plate of the located reflector absorbs an impact applied to the top of the lower reflector.

Further, the side plate buffering portion, which is disposed between the side plates of the adjacent reflectors, prevents the side plates from coming into contact with each other and buffers the side plates, particularly, the upper side of the adjacent reflectors. The corner portion formed by the side plate and the top plate of the reflecting plate to be buffered shocks applied to the side plate of the reflecting plate located on the lower side, and the frame forming flange of the side plate of the lower reflecting plate is the upper reflecting plate. Absorbs the impact applied to the side plate of.

In addition, the side plate buffering part prevents the contact between the frame-forming flange portions of these reflectors by floating the reflector located on the upper side of the adjacent reflectors from the reflector located on the lower side. . In this manner, the buffer having the above-described structure prevents mutual contact and cushions each portion of the adjacent reflector.
