Description

[Detailed Description of the Invention] The present invention relates to a so-called decorative cover for a lighting duct, which allows a lighting fixture to be plugged into any location on a wiring track.

Generally, when a lighting duct is hung from the ceiling,
In order to improve the appearance or to give a sense of stability by thickening the outer shape, a decorative cover is applied.

However, since conventional decorative covers have been integrated, for example, as shown in FIG. Ta.

Therefore, in order to maintain the strength of the cover, it is necessary to use a metal material such as aluminum or a thick resin, and there is also a drawback that it cannot be easily attached to an existing lighting duct.

The aim of the present invention is to solve the above problems.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

In the embodiment shown in Fig. 2 a, l), the synthetic resin cover 4 consists of two identical cover pieces 4a and 4b, each protruding from the center in the width direction of the cover pieces 4a and 4b. A fitting protrusion 6 and a fitting protrusion 7 provided at symmetrical positions on the end face of the hollow square member 5 are fitted into each other to form a substantially H-shaped cover 4.

The tip of the mating protrusion 6 bulges out in a hook shape and becomes thinner toward the tip, while the bottom of the mating concave 7 has the same shape as the tip of the mating protrusion 6, so that both Once it is fitted, it cannot be easily removed.

The width of both ears 8 of each cover piece 4 a , 4 b is approximately the same as the vertical width of the lighting duct 3 , and when both cover pieces 4 a , 4 b are joined, the width between each ear piece 8 is approximately the same as the vertical width of the lighting duct 3 . The interval between the two is approximately the same as the width of the duct 3, and the duct 3 is clamped by the elasticity of the resin.

Each of the cover pieces 4a and 4b is an extruded piece made from the same mold, and the above-mentioned protruding stripes 6 and grooved stripes 7 are formed on the cover pieces 4a and 4.
Since each cover 4 is provided along the entire length in the longitudinal direction of
A notch 9 is provided in the above-mentioned joint surfaces of 1 and 4b, and the hanging fitting 2 is passed through the cutout 9.

In this embodiment, the cover 4 has a substantially cylindrical shape, but the cover pieces 2a and 2b may have a substantially U-shaped cross section as shown in FIG. , 2b can be freely changed according to surrounding conditions and preferences.

The present invention is constructed as described above, and the decorative cover that covers both sides and the top surface of the duct includes the left and right cover pieces 4a,
4b, and both cover pieces are joined above the duct by the fitting river unevenness, so the decorative cover can be installed or replaced while the lighting duct is fixed to the hanging bracket, and the cover can be installed from the beginning. Since the cover itself does not carry any load, it can be made of relatively low-strength materials such as plastic, and thin-walled materials can be used.

Moreover, the decorative cover only needs to be attached at the final stage of the lighting duct installation process, and there is no risk of the cover becoming dirty or scratched during the process and spoiling its aesthetic appearance.

Further, by attaching the cover by fitting it in, there is an advantage that work at high places can be carried out easily and safely.

Furthermore, according to the present invention, each of the cover pieces 4a, 4b is provided at a symmetrical position on one side surface of the hollow square piece 5 with fitting projections and depressions 6.7.
Since both ear pieces 8 extend symmetrically from the periphery of the other side, both cover pieces have exactly the same shape, and are used by appropriately cutting the extruded long piece. It is possible,
It has the advantage that construction work is easy and manufacturing cost is extremely low.

Claims (1)

[Scope of utility model registration request] The left and right cover pieces form a joint resin cover that covers both sides and the top of the lighting duct suspended by the hanging fittings, and the fitting grooves provided on each cover piece allow both cover pieces to be placed above the lighting duct. A decorative cover for a certain lighting duct, wherein the cover pieces are joined together and a notch is provided on the joint surface of each cover piece to allow the hanging fitting to pass through.
