【Example】

 FIG. 1 is an exploded explanatory view schematically showing a planar lighting device A according to an embodiment of the present invention, and FIG. 2 is a partially cutaway front view schematically showing the planar lighting device A. Fig. 1 shows a planar lighting device A that is attached to a concrete frame B that constitutes the side wall (handrail) of a housing complex and is used as a blindfold fence.

In the above-described planar lighting device A as a blindfold fence, a plurality of vane plate materials 4 made of synthetic resin are held by a plurality of core materials 3 ... The upper and lower ends of the plurality of core members 3 are horizontally laid, and vertical bars 2 are respectively provided between one end and the other end of the upper and lower trees 1, 1. It was distributed.

FIG. 3 is an exploded perspective view showing a part of the core material 3. The core 3 is composed of a long hollow pillar 31 and a plurality of short auxiliary pillars 36 divided at a plurality of longitudinal positions. As shown in FIG. 3 and FIG. 4, the support column 31 is provided with recessed grooves 32 1, 32 at symmetrical positions on the front surface and the rear surface and screw pockets 33, 34 for tapping at predetermined positions on the inner surface side. ing. There are three types of auxiliary columns 36, one arranged at the bottom stage, one arranged at the middle stage, and one arranged at the top stage. The auxiliary columns 36 arranged at the middle stage are shown in FIG. 3 and FIG. 3 and 6, the auxiliary column 36 arranged at the uppermost stage is shown in FIG. 3, and the auxiliary column 36 arranged at the lowermost stage is shown in FIG. As can be seen from these figures, the auxiliary column 36 arranged in the intermediate stage has the lower end edge 36a and the upper end edge 36b inclined at the same angle as the inclined plate portion 43 of the vane plate member 4 described later, and thus the uppermost stage. Only the lower edge 36a 'of the auxiliary column 36 arranged is inclined at the same angle as the inclined plate portion 43 of the blade plate 4 and the upper edge 36b' is horizontal, and the auxiliary column 36 arranged at the lowermost stage has the upper edge 36b ". Only the inclined plate portion 43 of the blade plate member 4 is inclined at the same angle, and the lower end edge 36a ″ is horizontal. Further, all the auxiliary columns 36 ... Are provided with ridges 38, 38 facing each other, and these ridges 38, 38 are slid into the recessed grooves 32, 32 on the column 31 side to be fitted therein. As a result, the auxiliary columns 36 are mounted on the support column 31 as shown in FIG. Then, with the support 31 and the auxiliary support 36 attached, they cooperate to form the core 3. In this case, by inserting a metal plate 35 over the entire height of the support column 31, the support column 31 is reinforced by the plate body 35 and can withstand a large wind pressure such as a strong wind. . The pillar 31 and the auxiliary pillar 36 of the core 3 are made of aluminum extruded products. As shown in FIG. 4, openings 41 having a shape and a size that allow the columns 31 of the core material 3 to be inserted therethrough are formed at a plurality of positions on the blade member 4. The opening 41 has substantially the same shape as the support column 31 and is slightly larger than the support column 31. The opening 41 has a shape and size such that the auxiliary support column 36 cannot be inserted when the support column 31 is inserted. The vane plate member 4 integrally includes an inclined plate portion 43 and a rising piece portion 44 and a falling piece portion 45 provided on the inclined plate portion 43, and is made of synthetic resin such as polycarbonate resin and is itself Has translucency.

Next, an example of an assembling procedure of the planar lighting device A will be described mainly with reference to FIG.

After the lowermost subtree 1 is slid-fitted to the lowermost auxiliary column 36 on the column 31 attached to the lower end, the column 31 is passed through the opening 41 of the blade plate member 4. After that, slidingly fitting the auxiliary struts 36 at the intermediate stage to the struts 31 and passing the openings 41 of the blade plate material 4 through the struts 31 are alternately repeated. Then, after the vane plate members 4 are arranged in a predetermined number of steps, the uppermost auxiliary column 36 is slidably fitted to the column 31. After that, the upper head 1 is attached to the upper ends of the columns 31. The support 31 is attached to the headstock 1 by fixing the headstock 1 to the screw pockets 33 and 34 of the support 31 shown in FIG. 5 using the attachment screws 61 and 62. The headstock 1 and the support 31 may be fixed to each other by using only one screw pocket 33 or 34 of the support 31. As a result of this, the headboard 1 is laid across the upper ends of the core material 3 horizontally. In FIG. 6, an arrow X indicates a step of passing the opening 41 of the blade plate member 4 at the third stage through the column 31, and an arrow Y indicates a step of slidingly fitting the auxiliary column 36 at the fourth stage on the column 31. is there. It should be noted that since the blade plate member 4 is formed with openings 41 ... Corresponding to the plurality of pillars 31 ..., These openings 41 ... Are simultaneously passed through the corresponding pillars 31.

When the plurality of blade members 4 are held by the plurality of core members 3 as described above, the plurality of blade members 4 are sandwiched by the upper and lower auxiliary columns 36, 36 and are spaced apart from each other. Is retained and fixed in the retained state. Further, since the blade plate member 4 has only a part of the peripheral edge of the opening 41 sandwiched between the upper and lower auxiliary columns 36, 36, even if a large wind pressure is applied to the blade plate member 4, a part of the peripheral edge of the opening 41 is formed. There is no possibility that the core material 3 will be lost and the function of holding the blade plate material 4 by the core material 3 will be impaired.

In the embodiment shown in FIGS. 1 and 2, after this, vertical bars 2 are arranged between the upper ends of the upper and lower sheds 1, 1 and between the other ends. The rectangular frame F shown is formed. The frame F serves to increase the strength of the entire surface lighting device A. Further, in order to obtain a long-area planar lighting device A, as shown in FIGS. 1 and 2, the upper and lower sheds 1, 1 are connected by a connector 5 to extend the length thereof. An auxiliary vertical rail 6 is interposed at the connecting point.

Next, when the above-mentioned planar lighting device A is attached to the frame B made of concrete which constitutes the passage side wall (handrail) of the housing complex via the support post 100, the steps shown in FIGS. As described above, the support members 400 and 500 are attached to the upper end portion and the lower end portion of the support post 100, and the planar lighting device A is held from above and below by these support members 400 and 500.

The planar lighting device A can be used not only as the blindfold fence described above, but also as a planar lattice of the window W as shown in FIG.

[Effect of device]

 According to the present invention, it is possible to provide a planar lighting device that is easy to assemble. Moreover, since each of the plurality of blade plate members is held by the core member while being sandwiched between the upper and lower auxiliary columns, even if the blade plate member receives a large wind pressure due to strong wind, the blade member is held by the core member. There is an effect that the function is not impaired.
