(Case body)
The housing body 100 has the base 101 and the solar cell holding part 102 as described above. 4 to 6 show the base 101 of the housing body 100. FIG.

The base 101 is a self-standing state as shown in FIG. 4, a first storage state folded in a plate shape as shown in FIG. 5, and a further folding from the first storage state as shown in FIG. It is possible to switch to the second storage state. In the present embodiment, the display body 1 can be easily carried by setting the base 101 to the first storage state or the second storage state.

  As shown in FIG. 4, the base 101 includes a base main body 111 formed in a rectangular plate shape to which the solar cell holding portion 102 is attached, and the base main body 111 so that the longitudinal direction thereof is in the vertical direction. And a self-supporting holding part 15 that holds the base so as to be self-supporting. The material of the base main body 111 and the self-supporting holding part 15 is not particularly limited. However, when foamed resin, cardboard, or the like is used, the weight can be reduced, and the portability can be improved.

  The base main body 111 has a pair of rectangular plate-like base bodies 112 arranged along each other, and a gap S (see FIG. 5) extending along the plate surface direction of the base body 112 between the pair of base bodies 112. (B) is formed. The pair of base bodies 112 are disposed on the front side and include a base body 112A to which the solar cell holding unit 102 is attached and a base body 112B disposed on the rear side. The base 112A is provided with four attachment portions 116 for attaching the solar cell holding portion 102 (the number is not particularly limited). The attachment portion 116 is provided on the upper side and the lower side of the base body 112A. Further, a rectangular opening 114 communicating with the gap S is formed in the base body 112A. The opening 114 is formed to accommodate the circuit board 60 in the gap S. Details of this will be described later.

  Although not shown, spacer members are provided at both ends in the width direction (the direction perpendicular to the longitudinal direction and the thickness direction) of the base body 112A and the base body 112B. The spacer 112 connects the base body 112A and the base body 112B, and a gap S having a thickness equivalent to the thickness of the spacer member is formed between the base body 112A and the base body 112B.

  As shown in FIGS. 5A and 5B, the gap S is opened at the upper end portion of the base body 111 and is opened at the lower end portion of the base body 111. 5A and 5B, the lower end opening portion of the gap S is indicated by reference numeral 5a, and the upper end opening portion is indicated by reference numeral 5b.

  As shown in FIGS. 4 and 5, the self-supporting holding portion 15 is provided so as to extend downward from the lower end portions of the bases 112 </ b> A and 112 </ b> B. , Referred to as “outside”.) Two support members 16 and 17 (holding body) arranged to be bendable, and arranged between the support members 16 and 17 and partially movable in the vertical direction. Has a moving body 20 inserted into the gap S.

  The two front and rear support members 16 and 17 are connected to the lower end of the moving body 20. As shown in FIG. 5, each support member 16, 17 is formed with a crease line 19 extending in the horizontal direction so as to divide the upper and lower sides, and further, a crease line extending in the horizontal direction also near the lower end portion. 19b is formed. Then, as shown in FIG. 4, the self-supporting holding portion 15 has the upper portions of the support members 16, 17 bent outward, and the lower portions of the support members 16, 17 bent inward via the crease line 19. The base body 111 is stably held from below so as to be able to stand independently by being formed in a substantially truss shape in a side view.

  As described above, the upper portions of the support members 16 and 17 function as an inclined body inclined with respect to the base bodies 112A and 112B of the base body 111, and the lower portions of the support members 16 and 17 connect the inclined body and the moving body 20. Functions as a connected body. The moving body 20 is connected to a portion below the crease line 19b in the lower part of the support members 16 and 17, and moves upward in the gap S along with the bending operation of the lower part of the support members 16 and 17. To do.

  The thickness of the moving body 20 is preferably designed to be larger than the gap S in consideration of the elastic force of the material used for the base body 111. In this way, since the movable body 20 can move while the base bodies 112A and 112B are slightly deformed by the elastic force, the base body 101 can be firmly assembled without rattling even if there is a slight dimensional error. Can do. In particular, when the base 101 is enlarged in order to manufacture the large display body 1, it is not necessary to worry about dimensional errors severely, so that the manufacturing cost can be reduced.

  As described above, the base 101 used in the present embodiment is capable of easily increasing its rigidity and being stable and independent by forming the self-supporting holding portion 15 in a substantially truss shape. Therefore, sufficient strength can be ensured even when the large-sized solar cell holding unit 102 is held.

  Moreover, in this base 101, the base main body 111 can be folded in two via the bent part 30, and as described above, the second storage state is further folded from the first storage state shown in FIG. It is possible to convert to.

  As shown in FIG. 5, the bent portion 30 includes a crease line 11 (folded portion) formed in the base body 112A and a cut portion 13 formed in the base body 112B. As shown in FIGS. 4A and 5A, the crease line 11 is formed to extend in the horizontal direction at an intermediate position between the central portion and the lower end portion of the base body 112A. On the other hand, as shown in FIG. 5B and FIG. 6A, the cut portion 13 is formed to extend in a horizontal direction at a position below the crease line 11, and this cut portion 13 divides the base body 112B into upper and lower portions.

  As shown in the state of FIG. 5 to the state of FIG. 6, the upper portion of the base body 111 can be bent forward along the crease line 11 and the notch 13. As a result, the base body 111 can be folded up and down as shown in FIG.

  Further, as shown in FIG. 5B, a projecting body 14 extending downward is formed on the lower end edge of the base body 112B of the base body 111 at the upper part of the base body 112B (upper side of the upper and lower sections). Part). As shown in FIGS. 5 and 6, the projecting body 14 is provided separately from the front base 112 </ b> A. Strictly speaking, the projecting body 14 is not connected to the lower part of the base 112A located below the crease line 11 by the spacer member described above, and is provided separately from the lower part of the base 112A. It has been.

  That is, the base 112 </ b> A and the base 112 </ b> B are connected by the spacer member described above, but the spacer member is divided into an upper part and a lower part with the bent part 30 interposed therebetween. And the upper part of a spacer member connects the upper part located above the crease line 11 of the base 112A, and the upper part located above the notch 13 of the base 112B. On the other hand, the lower part of the spacer member connects a lower part located below the crease line 11 of the base 112A and a lower part located below the notch 13 of the base 112B. The upper portion of the base 112A and the upper portion of the base 112B, and the lower portion of the base 112A and the lower portion of the base 112B are connected only by the crease line 11. Therefore, the upper part of the base main body 111 can be bent forward along the crease line 11, and as a result, it can be folded in the vertical direction. Here, if the above-mentioned protrusion 14 is connected to the lower part of the base body 112A, the base body 111 cannot be folded. Therefore, the protrusion 14 is provided separately from the lower part of the base body 112A.

  In addition, as long as appearance does not consider appearance, at least one part should just protrude below, and the shape may be shapes, such as an inverted triangle and uneven | corrugated shape, for example. As will be described later, the projecting body 14 functions as a guide body that guides the moving body 20 so that the moving body 20 is smoothly inserted into the gap S.

  Here, an arrangement relationship between the bent portion 30 and other elements of the base 101 will be described. As shown in FIG. 5, the distal end portion of the moving body 20 is disposed beyond the upper end portion (cut portion 13) of the lower portion of the base body 112 </ b> B, and is inserted into the gap S above the moving body 20. The Note that the distal end portion is not disturbed when the base main body 111 is folded, and thus the distal end portion is disposed in a range not exceeding the crease line 11. Further, the reason that the distal end portion needs to be disposed beyond the upper end portion of the lower portion of the base body 112B is that when the moving body 20 moves, a case where it is caught with the upper end edge of the lower portion of the base body 112B is assumed. .

  Further, the protrusion 14 described above is arranged so that at least a part of the tip of the moving body 20 overlaps before the moving body 20 moves (state of FIG. 5). Thereby, the movable body 20 is smoothly guided to the gap S without being caught by the lower end edge of the upper portion of the base body 112B when the base body 111 is assembled.

  Moreover, as shown in FIG. 4, the bending part 30 is provided below the attachment position of the lower end part of the solar cell holding part 102 in the base 112A. That is, the bent portion 30 is provided below the attachment portion 116 provided on the lower side of the attachment portions 116 provided on the base body 112A.

  The base 101 having the above-described configuration is assembled as follows as an example. First, the upper part of the base body 111 shown in FIG. 6 is lifted upward via the crease line 11 and expanded as shown in FIG. 5, and a support member is placed on the mounting surface on which the base body 111 is placed. The lower end surfaces of 16 and 17 are pressed against each other. As a result, as shown in FIG. 4, the lower portions of the support members 16 and 17 are bent inward via the crease line 19, and the upper portions of the support members 16 and 17 are bent outward via the crease line 18. . And the upper part of the supporting members 16 and 17 inclines in the front-back direction with respect to the base | substrates 112A and 112B of the base main body 111, and the assembly of the self-supporting holding part 15 is completed.

  At this time, the moving body 20 is guided by the projecting piece 14 with the bending operation of the lower portions of the support members 16 and 17, and the distal end portion thereof is inserted into the gap S at the upper portion of the base body 111. As a result, as shown in FIG. 4, the upper portion of the base body 111 is erected and the assembly of the base 101 is completed.

The holding panel 103 holds the solar cell panel 40 on one surface (front surface) of the pair of surfaces, and is attached to the base body 112A of the base body 111 on the other surface (rear surface). Yes. In the illustrated example, four solar cell panels 40 are attached to the front surface of the holding panel 103 side by side in the vertical direction. For example, the solar cell panel 40 may be attached to the holding panel 103 with a screw, or may be attached to the holding panel 103 with an adhesive.

  The rear surface of the holding panel 103 is detachably attached to the mounting portion 116 provided on the base body 112 </ b> A of the base body 111 by, for example, Velcro (registered trademark). The attachment mode for the base body 112A is not limited to this, and various modes can be adopted. For example, the holding panel 103 may be detachably attached to the base 112A by providing a hook on the attachment portion 116 of the base 112A and engaging a hole, ring, or the like provided on the rear surface of the holding panel 103.

  Further, the holding panel 103 is formed with a rectangular opening 103A penetrating in a direction orthogonal to the plate surface.

As shown in FIG. 7, the depth of the accommodation hole 104 </ b> A is preferably larger than the thickness of the solar cell panel 40. The laminated panel 104 is formed of PET or the like, for example, and is formed in a rectangular shape having substantially the same dimensions as the holding panel 103 in the illustrated example. The front surface of the laminated panel 104 is preferably colored with a color close to the color of the solar cell panel 40, such as gray, dark blue, or black. More specifically, it is preferable that the difference between the lightness of the front surface of the solar cell panel 40 and the lightness of the front surface of the laminated panel 104 is adjusted to be within 2.3. In this case, when the display layer 2 is attached, it is possible to suppress the occurrence of color unevenness on the display surface 2A of the display layer 2 due to the influence of the members arranged on the rear side of the solar cell panel 40 and the like. In the present embodiment, the accommodation hole 104A is formed in the laminated panel 104, but such accommodation hole 104A may not be formed. In this case, the laminated panel 104 colors (prints) a color close to the color of the solar cell panel 40 on a portion other than the portion facing the solar cell panel 40 of the transparent panel that entirely covers the holding panel 103.
