Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a shade for a lighting fixture in which a plastic frame is attached to the outside of the shade body, and particularly relates to the structure of the plastic frame.

[Conventional technology]

5 and 6 show a conventional shade for lighting equipment shown in Japanese Utility Model Publication No. 52-54184, in which 1 is the shade body, 2 is a plastic frame attached to the outside of the shade body 1, and the plastic frame is attached to the outside of the shade body 1. The frame 2 is constructed by a combination of frame pieces 3. A box-shaped fitting piece 4 is provided at one end of each frame piece 3, and each frame piece 3
A box-shaped fitting piece 5 having a size to receive the fitting piece 4 is provided at the other end, and protrusions 6 having a triangular cross section are provided at the upper and lower ends of the fitting piece 4, and the fitting piece 5 Concave portions 7 that fit into the convex portions 6 are also provided at the upper and lower ends of.

In the above configuration, the fitting piece 4 is pushed in the direction of arrow A in FIG. furthermore, fitting pieces 4 and 5 are formed.
The plastic frame 2 is attached to the shade body 1 by engaging the fitting portions with support projections 8 provided at each corner of the shade body 1.

[Problem that the invention attempts to solve]

However, in the above-mentioned conventional shade for lighting equipment, the fitting pieces 4 and 5 protrude vertically from the horizontal frame 9 of the frame piece 3 at the connecting portion of each frame piece 3 in the plastic frame 2, which is not desirable in terms of appearance. Nakatsuta.

The present invention was made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a shade for a lighting fixture that has a good appearance.

[Means for solving problems]

In the present invention, L-shaped connection pieces are provided at both ends of each frame piece constituting the plastic frame so that the width direction is the vertical direction, and a protrusion is provided on the side surface of one connection piece, and a protrusion is provided on the side surface of the other connection piece. A fitting part is provided on the side surface of the frame to fit with the protruding part, and the protruding part of the connecting piece of the different frame pieces is fitted with the fitting part to form a plastic frame.

[Effect]

The plastic frame is constructed by fitting the protruding part formed on the side surface of the connecting piece provided on the frame piece so that the width direction is the vertical direction, and the fitting part, so that the connecting part of the frame piece protrudes vertically. Never.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4, 10 is a shade main body, 11 is a plastic frame attached to the shade main body 10, and the plastic frame 11 is formed by combining each frame piece 12. Each frame piece 12 has two flat plate-shaped horizontal machines 13 disposed almost horizontally, and an L-shaped horizontal machine 13 that is attached oppositely to each other at both ends between the horizontal machines 13 on the inner end side of the horizontal machine 13. It is composed of connecting pieces 14 and 15. The ends of each transverse machine 13 flare outwardly at a 45° angle. Furthermore, the width direction of each of the connecting pieces 14 and 15 is the vertical direction, and the respective base portions 14
a, 15a are attached so as to be parallel to the horizontal machine 13, and a recess 14b is formed in the base 14a of the connecting piece 14. Further, a protruding part 14d having a triangular cross section is formed on the inner surface of the upright part 14c of the connecting piece 14, and a square hole 15c is provided in the base part 15a of the connecting piece 15 to fit into the protruding part 14d. 15b is an upright portion of the connecting piece 15. In addition, the base 1 of the connecting piece 14
4a and the upright portion 14c have approximately the same width and length.

In the above configuration, as shown in FIG. 3, when two frame pieces 12 are arranged at right angles and one frame piece 12 is moved in the direction of arrow D, the upright portion 1 of the connection piece
5b is accommodated in the recess 14b of the connection piece 14 in the other frame piece 12, and the square hole 15c is fitted into the protrusion 14d, so that one ends of the two frame pieces 12 are connected as shown in FIG. . Similarly, by connecting the ends of the four frame pieces 12, a square plastic frame 11 is formed, and this plastic frame 11 is attached to the shade body 10 by engagement or the like. Note that the square hole 15c may be a recessed portion.

[Effect of idea]

As described above, in the present invention, L-shaped connecting pieces are attached to both ends of each frame piece constituting the plastic frame so that the width direction is vertical. A fitting part is provided on the side surface of the connecting piece to fit with this protruding part, and by fitting the protruding part of the connecting piece on different frame pieces and the fitting part, each frame piece is connected and the plastic frame is made. Since the connecting portions of each frame piece do not protrude vertically, it is possible to obtain a plastic frame and a shade for a lighting fixture that have a good appearance. Further, the width and length of the base and the upright portion of one of the connecting pieces located on the outside at the corner portion of the frame piece are approximately the same, resulting in a well-balanced external appearance. Furthermore, the upright part of the other connecting piece is fitted into the recess provided at the base of one connecting piece, and the protruding part provided on the inner surface of the upright part of one connecting piece is fitted into the recess provided at the base of the other connecting piece. The fitting parts are fitted together, and the separation of each connection piece in the direction opposite to the assembly direction is prevented by the engagement between the protruding part and the fitting part, and the separation in the direction perpendicular to the assembly direction and the separation due to torsional force are prevented. This is prevented by the fit between the recessed portion and the upright portion. Therefore, the connection strength of each frame piece becomes stronger.
