It was assembled using the configuration shown in FIGS. 5-7.

なる難点もあつた。 The one in Figure 5 is a wooden frame (hereinafter referred to as a wooden frame).
A groove 11 is provided in the upper frame 1 constituting the frame 1, and grooves 21 and 22 are provided in each of the two sides of the lower frame 2, and at the same time as the wooden frame is assembled, the side panel _P1 and the bottom surface are attached as shown in the same figure. The panel _P2 is fitted into each of the grooves 11, 21, and 22. In this case, it is necessary to assemble the panel at a woodworking shop, so
This method lacks workability due to problems such as panel stains due to adhesion of dust in the workplace and the preparation of cross-sectional processing of the wooden frame and panel assembly, and also has the disadvantage that it is impossible to replace or repair the panel after assembly. Ta. Furthermore, there was also the problem that the cross-sectional dimensions of the wooden frame, particularly the lower frame 2, were large.

きくなる難点があつた。 The one in Figure 6 has a stepped notch 2 in the lower frame 2.
3 and 24 are provided, and the side panel P ₁ and bottom panel P ₂ fitted into these notches 23 and 24 are secured to the lower frame 2 by an L-shaped corner holding fitting 41 fixed to the lower frame 2 with wood screws 31. At the same time, the upper end of the side panel _P1 is held by a presser metal fitting 42 which is fixed to the upper frame 1 with wood screws 32. In this case, not only does it take a lot of man-hours to process the cross section of the wooden frame, but the panel is also likely to warp due to thermal expansion of the panel due to the heat generated by the light source and ballast installed inside the shade. In order to prevent this warping, it is effective to lengthen the presser metal fittings 4 or increase the number of them, but doing so will increase the number of parts including the wood screws 3, which will increase costs. , assembly work efficiency decreases. It also becomes difficult to replace or repair panels. Furthermore, as in the case of FIG. 4, there was a problem in that the cross-sectional dimensions of the wooden frame, particularly the lower frame 2, were large.

Or it is glued to the lower frame 2. In this case, the adhesive may protrude from the outside surface of the shade, the adhesive strength may deteriorate over time, resulting in panel peeling, or the panel may be deformed due to thermal expansion. Therefore, there is a drawback that the product value tends to decrease. Furthermore, it is completely impossible to replace or repair the panel.

としている。(c) Purpose of the invention This invention was created in view of the above circumstances, and is designed so that the panels and reflectors disposed inside the wooden frame cooperate with each other to form a framework. The purpose of the present invention is to provide a shade for lighting equipment that has good assembly workability, allows easy replacement and repair of panels after assembly, and has high commercial value.

いる点を要旨としている。(d) Structure and effect of the invention In order to achieve the above object, the shade for a lighting fixture of this invention has a side panel having a claw piece projecting outwardly at the upper end and an upper rib projecting inwardly. The end of the lower panel that is inserted into the groove of the frame and lowered into the stepped part of the lower frame is pressed by the lower rib provided at the lower end of this side panel, and the claw piece is pressed against the lower rib of the lower edge of the side panel. The gist is that the reflector is fitted into the groove and that the end of the reflector is supported by the upper rib.

換・補修も簡単にできるようになる。 With this configuration, the side panel is reliably positioned in the vertical direction and in the inner and outer directions of the shade by the engagement between the groove of the upper frame and the claw piece, and the engagement between the groove of the lower frame and the lower end of the side panel. . Further, the lower panel is reliably positioned by the stepped portion of the lower frame and the lower rib of the side panel. Further, the reflector is supported by the upper rib of the side panel. Therefore, when assembling the shade, there is no need for panel holding fittings or adhesives, which improves assembly workability compared to conventional methods, and reduces the number of parts and the number of man-hours required to process the cross section of the wooden frame. This leads to cost reduction, and also eliminates the unsightly appearance caused by adhesive protrusion, increasing product value. In addition, the side panels, bottom panel, and reflector are not fitted into the wooden frame, but work together to form a framework, resulting in a structure that can absorb the thermal expansion of each panel, causing problems such as panel deformation. Furthermore, since it is easy to disassemble and assemble, it is convenient for cleaning, and the panel can be easily replaced and repaired.
