Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a lighting shade.

[Conventional technology]

In conventional lighting shades, as disclosed in Japanese Utility Model Application Publication No. 50-15587, protrusions are formed on the inner circumferential surface of a frame-shaped decoration (hereinafter referred to as a decorative frame) to sandwich the outer edge of the shade from above and below.

[Problem to be solved by the invention]

In recent years, there has been an increasing demand for lighting equipment that has a large decorative frame attached to the shade to improve its appearance and add value.

For example, there is an increasing tendency to use larger cross-sectional shapes for decorative frames made of plastic molded products attached to the outer periphery of shades.

However, simply using a large solid cross-sectional shape will cause various inconveniences in terms of material cost, molding cycle, part weight, etc.

The prior art did not give sufficient consideration to the above points.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a lighting shade that can efficiently reduce the weight of a decorative frame with a large cross section and can be manufactured at low cost.

[Means to solve the problem]

The purpose of the above is to steal meat from the inside part of the decorative frame, which is divided into two vertically.
This is achieved by applying the above-mentioned function and engaging the decorative frame divided into two parts with the engaging portion provided in the meat-stealing portion.

[Effect]

By providing the above means, it is now possible to efficiently steal meat even with large cross sections, making it possible to reduce weight and improve formability, and to efficiently reduce the weight of decorative frames with large cross sections, making it possible to reduce costs. Become.

〔Example〕

The present invention will be explained below based on the illustrated embodiments. An embodiment of the present invention is shown in FIGS. 1-4.

The illumination shade 1 has a decorative frame 3 attached to its outer edge 2. In the lighting shade 1 configured in this way, in this embodiment, the decorative frame 3 is divided into two vertically into a decorative frame a.
The inside portions of a and 3b are cut out, and the decorative frames 3a and 3b, which are divided into two parts, are engaged with each other by engagement portions provided in the cutout portions. By doing this, it becomes possible to steal meat efficiently even with a large cross section, making it possible to reduce weight and improve formability, and to efficiently reduce the weight of the decorative frame 3 with a large cross section, making it possible to reduce costs. Lighting shade 1
can be obtained.

That is, the lighting shade l is provided with an outer edge part 2 around the entire lower end, and the decorative frames 3a and 3b are cut in cross section into a roughly oval shape, and as shown in FIG. Elastic locks 11#I4.4a are arranged inside each opposite side near both corners, and a positioning receiving part 5 is provided in the center.
will be established. On the other two sides, hooks 6 and 6a for locking the locking legs 4 and 4a are provided near both corners, and a protrusion 7 that engages with the receiving portion 5 is provided in the center. In addition, as shown in FIG. 2, there is a step a between the inner and outer end surfaces of the decorative frames 3a and 3b.
, and the outer edge 2 of the lighting shade 1 is held between them.

By doing so, the assembly can be performed as described below. After placing the outer edge part 2 of the illumination shade l on the inner end surface of the decorative frame 3a, the decorative frame 3b inverted about the diagonal is pressed against the decorative frame 3a from above. In this way, as shown in FIG. 4, the locking leg 4.4a and the hook parts 6, 6a are elastically locked, and the positioning projection 7 and the receiving part 5 are They are engaged, and the assembly of the decorative frame 3 is completed.

As described above, according to this embodiment, even a large cross section can be efficiently stripped of meat, and weight reduction and moldability can be improved, so that cost reduction can also be achieved.

Moreover, since the end face of the shade is covered from above and below with a decorative frame divided into two parts, the appearance is improved due to the sense of unity.

[Effects of invention]

As described above, the present invention is to efficiently reduce the weight of a decorative frame with a large cross section and to achieve a low cost, thereby obtaining a lighting shade that can efficiently reduce the weight of a decorative frame with a large cross section and to achieve a low cost. I can do it.
