Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture shade body provided with a conical column and a pair of supports that fit with the conical column.

[Conventional technology]

In a pendant-type lighting fixture or the like used by hanging from a ceiling, a shade A for a lighting fixture as shown in FIGS. 7 and 8 is generally used. It is hollow and has an upper opening b with a smaller diameter on the upper side and a lower opening c with a larger diameter on the lower side. The upper opening b is an opening for mounting a lamp socket or the like (not shown), and the lower opening c is for lamp replacement.

The structure of such a conventional package of shade A for lighting equipment is as shown in FIGS. 7 and 8. FIG. As shown in the figure, a columnar column 4 'having a columnar shape corresponding to the diameter of the upper opening b is fitted into the upper opening b, and the lower side of the columnar column 4' is loosely inserted into the lower opening c. I do. The columnar support 4 ′ includes an upper protruding portion 41 and a lower protruding portion 42 protruding from the lighting fixture shade A. They are stored in a packaging box 1 of an appropriate size. The upper abutment 31 including the base plate portion 45 and the rising pieces 43 around the base plate portion 45
Is provided. A lower support 32 'including a base plate portion 46 and a rising piece 44 around the base plate portion 46 is provided. The upper support 31 is arranged on the upper part of the packaging box 1 so that the base plate portion 45 is on the lower side. The lower abutment 32 'is arranged at the lower part of the packaging box 1 so that the base plate portion 46 is on the upper side. A cutout hole 55 is formed in the base plate portion 45 of the upper support 31 to fit the upper protrusion 41. Base plate part on lower abutment 32 '
46 is provided with a hole 56 'to be fitted with the lower protruding portion 42.

[Problems to be solved by the invention]

In the conventional FIGS. 7 and 8, the shade A for a lighting fixture is captured by the middle columnar support 4 'or the upper support 31 and the lower support 32', but this is not sufficient. There is a gap l ₁ between the larger lower opening c and a cylindrical post 4 'caliber luminaire for shade A, shade A luminaire swings. Even shade A luminaire is swung, as the shade A lighting fixture does not touch the package box 1 the inner surface, there is also sufficiently wide gap l ₂ of the shade A peripheral luminaire, when the The size of the packaging box 1 increases accordingly. For this reason, the corner packing 6 for reducing the swing of the lighting equipment shade A is disposed between the lighting equipment shade A and the four corners of the packaging box 1. On the other hand, the corner support of the lower support 32 'is heavy. The weight load of shade A for lighting fixtures is exclusively for the lower support 3
Because it is added to 2 ′, the lower support 32 ′ is deformed when it receives vibration or impact during transportation. In order to prevent this, another support packing 5 for supporting the base plate portion 46 of the lower support 32 'from below is required.

Corner packing 6 and support packing 5 as described above
In such a case, the number of parts increases, and packaging takes time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging structure or a package in which a shade for a lighting fixture hardly swings, the number of packing points is small, and a packaging operation is easy.

[Means for solving the problem]

In the present invention, a conical column is used instead of the columnar column. The shape of the conical strut is such that its inclined surface contacts the periphery of the small-diameter upper opening of the lighting fixture shade and the periphery of the large-diameter lower opening. In addition, the conical strut can be fitted into a large hole formed in the base plate portion of the lower abutment.

[Action]

The conical strut of the present invention tends to hold the shade for lighting fixtures and the lower abutment obliquely on the inclined surface, and to support the oblique lower side. At least a portion of the weight load of the lighting fixture shade is borne and supported by the conical strut.

〔Example〕

An embodiment of the present invention shown in FIGS. 1 to 5 will be described.
In this description, the part numbers and names of the parts shown in FIGS. 7 and 8 are used as they are or slightly changed, and a part of the overlapping description will be omitted as appropriate. The embodiment shown in FIGS. 1 to 5 is a hollow shade, which has an upper opening b having a small diameter on the upper side and a package of a shade A for a lighting fixture having a lower opening c having a large diameter on the lower side. It is.

In this package, the inclined surface 50 has an upper opening b and a lower opening c.
Are provided with conical struts 4 that are in contact with the respective peripheral edges. Conical column 4
Includes an upper protruding portion 41 and a lower protruding portion 42 protruding from the shade A for a lighting fixture. The package includes a packaging box for accommodating a lighting apparatus shade A and a conical column 4. An upper support 31 including a base plate portion 45 and a rising piece 43 around the base plate portion is provided. The lower abutment 32 including a base plate portion 46 and a rising piece 44 around the base plate portion 46 is provided. Upper abutment
31 is arranged on the upper part of the packaging box 1 so that the base plate portion 45 is on the lower side. The lower abutment 32 is arranged at the lower part of the packaging box 1 so that the base plate portion 46 is on the upper side. The base plate portion 45 of the upper support 31 is provided with a small hole 55 having a small hole diameter to be fitted to the upper protruding portion 41. The base plate portion 46 of the lower support 32 is provided with a large-diameter hole 56 to be fitted with the lower protruding portion 42.

The conical strut 4 is formed by bending a corrugated cardboard made by punching into a fan shape as shown in FIG. 2 along a required folding curve so as to have a conical shape (more precisely, a polygonal pyramid shape). Is made by gluing the glue allowance pieces 40. The outer surface of the conical column 4 is an inclined surface 50. The outer diameter of the height h ₁ only lower portion from the upper end 51 of the conical strut 4 is compatible with a small upper opening b of the diameter of the shade A luminaire, a small vent hole 55 both fit of the upper abutment 31. Further, the range of height h ₁ is next to the upper projection 41 which projects from the shade A luminaire, height h ₁ corresponds to the length of the start-up pieces 43 of the upper abutment 31 periphery. The outer diameter of only a height h ₂ high position from the lower end 52 of the conical strut 4 is compatible with a large lower opening c caliber shade A luminaire fits both large drain hole 56 of the lower abutment 32 . Further, the range of height h ₂ is the lower protruding portion 42 becomes protruding from shade A luminaire, height h ₂ corresponds to the length of the start-up pieces 44 of the lower abutment 32 periphery.

The swing of the conical column 4 in the horizontal direction is regulated by the upper support 31 and the lower support 32. The swing of the lighting fixture shade A in the horizontal direction is restricted in the vicinity of the upper projecting portion 41 and the lower projecting portion 42 of the conical column 4. Part of the weight load of the lighting fixture shade A is shared by the conical strut 4 via the upper opening b and the lower opening c. The rest is shared by the lower support 32. In addition, a part of the weight load received by the lower support 32 is shared by the conical column 4 via the large hole 56. The lighting fixture shade A / lower support 32 can be supported from below by the conical support 4 because it has a conical shape instead of a cylindrical shape. When the upper opening b and the lower opening c of the lighting fixture shade A have the same diameter, the use of the conical strut 4 is impossible and the present invention cannot be applied.

The role of the conical strut 4 is to regulate undesired horizontal swinging of the lighting fixture shade A at the two upper and lower cylinder locations. In addition, it is to support the lighting equipment shade A from below at the two places. Also, the lower abutment 32
Is to support it from below so that it does not collapse or deform. In the embodiment shown in FIGS. 1 to 5, the corner packing disposed outside the shade A for the lighting fixture and the support packing for supporting the lower support 32 from below are not used, but their functions are conical pillars. Complemented by four. In addition, since corner packing and support packing are not required, and the number of parts is reduced accordingly, the packaging operation is also facilitated.

A modified embodiment of FIG. 6 will be described. 1
The conical column 4 in the embodiment shown in FIG. 5 is formed by bending corrugated cardboard. Instead, the same effect can be obtained by using a molded product 4a formed in a conical shape with styrene foam or the like as shown in FIG. 6 as a conical support.

〔The invention's effect〕

The present invention focuses on a small-diameter upper opening and a large-diameter lower opening of a shade for a lighting fixture, and uses a conical strut having a shape adapted thereto. According to this,
The lighting fixture shade is less likely to oscillate, the number of packing points is small, and the packaging operation is facilitated.
