For this reason, even when a transparent pocket is adopted as the attachment means, if a design such as a character, an illustration, or a pattern is applied to the portion of the clothing covered by the solar cell, the design is hidden by the solar cell. As a result, there is a disadvantage that the design property of the clothing is impaired.

Means for Solving the Problems

[0005] Each aspect of the clothing with a solar cell for solving the above problems is described. [Aspect 1] A clothing with a solar cell, comprising a clothing body and a solar cell unit attached to the outer surface of the clothing body, wherein the solar cell unit includes a support portion attached to the outer surface of the clothing body, a base portion supported by the support portion and configured to be deformable between a deployed state covering the outer surface of the clothing body and a stored state with a smaller area covering the outer surface of the clothing body than the deployed state, and a solar cell fixed to the base portion and located on the outer surface side of the base portion in the deployed state.

[0006] According to the above configuration, in the stored state of the base portion, the area of the clothing body covered by the base portion is smaller than that in the deployed state. Therefore, by applying a design such as characters, illustrations, or patterns to the portion of the clothing body covered by the base portion in the deployed state, the design can be exposed to the outside in the stored state. Thus, it is possible to suppress the impairment of the design property of the clothing while including the solar cell unit.

[0007] [Aspect 2] The base portion and the solar cell are each in a sheet shape having flexibility, and the support portion includes a shaft portion connected to the proximal end of the base portion and a shaft support portion rotatably supporting the shaft portion. In the stored state, the base portion is wound around the shaft portion. The clothing with a solar cell according to [Aspect 1].

[0008] According to the above configuration, in the stored state of the base portion, the base portion is wound around the shaft portion by rotating the shaft portion. Therefore, the clothing with a solar cell can be embodied with a simple configuration.

[0009] [Aspect 3] The support portion includes a biasing member that biases the shaft portion to rotate in the direction of winding up the base portion. The clothing with a solar cell according to [Aspect 2].

[0010] According to the above configuration, the base portion in the deployed state is automatically wound up by the biasing force of the biasing member. Therefore, the labor of winding up the base portion in the deployed state can be saved. Accordingly, the usability of the solar cell unit is improved.

[0011] [Aspect 4] When the proximal end side and the distal end side of the base portion in the deployed state are the proximal end side and the distal end side, the base portion has a plurality of slats in the shape of strips, and the support portion connects one ends and the other ends in the width direction of the plurality of slats, respectively, and a pair of connecting strings extending toward the proximal end side, and is connected to the slat constituting the distal end of the base portion in the deployed state among the plurality of slats and is loosely fitted to the other slats excluding the slat constituting the distal end, and a through string extending toward the proximal end side, a first operation portion for changing the inclination angle of the slats with respect to the outer surface of the clothing body by operating the pair of connecting strings, and a second operation portion for adjusting the interval between the slats by operating the through string. In the deployed state, the plurality of slats are in a posture along the outer surface of the clothing body and are arranged adjacent to each other in the width direction of the slats. On the other hand, in the stored state, the plurality of slats are in a posture intersecting the outer surface of the clothing body and are configured to overlap each other in the thickness direction of the slats. The clothing with a solar cell according to [Aspect 1].

[0012] According to the above configuration, since the solar cell unit is constituted by a plurality of strip-shaped slats, a pair of connecting strings, a through string, a first operation portion, and a second operation portion, a so-called blind curtain structure is formed. Thereby, even when the solar cell does not have flexibility, the clothing with a solar cell can be realized.

[0013] [Aspect 5] The base portion is provided with a locking portion for detachably locking the base portion in the deployed state to the clothing body. The clothing with a solar cell according to any one of [Aspect 1] to [Aspect 4].

[0014] According to the above configuration, the base part in the deployed state is detachably locked to the clothing body by a locking part provided separately from the support part. Therefore, the base part in the deployed state can be stably held with respect to the clothing.

[0015] [Aspect 6] The solar cell is a perovskite-type solar cell, and the clothing with a solar cell according to [Aspect 1].

[0016] According to the above configuration, by using a flexible perovskite-type solar cell, the shape of the solar cell can be deformed following the change in the shape of the base part.

[0020] As shown in FIGS. 1 and 2, the clothing with a solar cell includes a clothing body 10 and a solar cell unit 11. <Clothing Body 10> As shown in FIGS. 1 and 2, the clothing body 10 has a design surface 10a with a design such as characters, illustrations, or patterns. In this embodiment, the design surface 10a is provided on the back of the clothing body 10.

[0021] Hereinafter, in the following description, the vertical direction of the clothing body 10 will be simply referred to as the vertical direction, and the horizontal direction of the clothing body 10 will be simply referred to as the horizontal direction. As shown in FIG. 2, a locked portion 15 is provided on the back of the clothing body 10. The locked portion 15 is attached below the design surface 10a on the back of the clothing body 10 and is adjacent to the design surface 10a. In this embodiment, the locked portion 15 is a hook-and-loop fastener sewn to the back of the clothing body 10.

[0022] <Solar Cell Unit 11> As shown in FIGS. 1 and 2, the solar cell unit 11 is attached to the back of the clothing body 10.

[0023] As shown in FIG. 1, the solar cell unit 11 has a support portion 20, a base portion 30, and a solar cell 40. In this embodiment, the solar cell unit 11 is embodied as a so-called spring-type roll curtain structure by the support portion 20 and the base portion 30.

[0024] (Support Portion 20) As shown in FIG. 1, the support portion 20 has a shaft portion 21 and a shaft support portion 22. The shaft support 22 is attached above the design surface 10a on the back of the clothing body 10 and is adjacent to the design surface 10a. The shaft support 22 is attached to the clothing body 10 via a bracket (not shown) fixed to the back of the clothing body 10. In the present embodiment, two shaft supports 22 are provided at intervals in the left - right direction.

[0025] The shaft portion 21 is cylindrical and is rotatably supported by two shaft supports 22 about the axis L1 of the shaft portion 21. (Base portion 30) As shown in FIG. 1, the base portion 30 is a flexible sheet - like shape and is supported by the support portion 20.

[0026] The proximal end 30a of the base portion 30 is connected to the shaft portion 21. The base portion 30 is configured to be deformable between a deployed state (see FIG. 1) that covers the design surface 10a of the clothing body 10 and a stored state (see FIG. 2) in which the area covering the design surface 10a of the clothing body 10 is smaller than in the deployed state.

[0027] As shown in FIG. 2, in the stored state, the base portion 30 is wound up by the shaft portion 21. As shown in FIG. 1, the base portion 30 is provided with a locking portion 31 that detachably locks the base portion 30 in the deployed state to the clothing body 10. The locking portion 31 is provided on the inner surface of the base portion 30 that faces the design surface 10a in the deployed state. The locking portion 31 is preferably provided at a position adjacent to the distal end 30b of the base portion 30. In the present embodiment, the locking portion 31 is a hook - and - loop fastener that is sewn to the inner surface of the base portion 30 and engages with the locked portion 15 of the clothing body 10.

[0028] (Biasing member 23) As shown in FIG. 1, inside the shaft portion 21, a biasing member 23 is provided that connects the shaft portion 21 and the shaft support 22 and rotationally biases the shaft portion 21 in the direction of winding up the base portion 30. In the present embodiment, the biasing member 23 is a coil spring.

[0029] (Solar cell 40) As shown in FIG. 1, the solar cell 40 is fixed to the base portion 30 and is located on the outer surface side of the base portion 30 in the deployed state.

[0030] The solar cell 40 is in the form of a flexible sheet. The solar cell 40 is preferably a perovskite solar cell. <Operation of the First Embodiment> As shown in FIGS. 1 and 2, in the stored state of the base portion 30, the area of the clothing body 10 covered by the base portion 30 is smaller than that in the deployed state. Therefore, by applying a design such as characters, illustrations, or patterns to the portion of the clothing body 10 that is covered by the base portion 30 in the deployed state, it is possible to expose the design to the outside in the stored state.

[0031] <Effect of the First Embodiment> (1-1) The solar cell unit 11 includes a base portion 30 that is supported by the support portion 20 and is configured to be deformable between a deployed state in which it covers the back surface of the clothing body 10 and a stored state in which the area covering the back surface of the clothing body 10 is reduced compared to the deployed state.

[0032] According to such a configuration, since the above-described operation is achieved, it is possible to suppress the loss of the design property of the clothing while including the solar cell unit 11. (1-2) The base portion 30 and the solar cell 40 are each in the form of a flexible sheet. In the stored state, the base portion 30 is wound around the shaft portion 21.

[0033] According to such a configuration, in the stored state of the base portion 30, the base portion 30 is wound around the shaft portion 21 by rotating the shaft portion 21. Therefore, the clothing with a solar cell can be realized with a simple configuration.

[0034] (1-3) The support portion 20 includes a biasing member 23 that biases the shaft portion 21 to rotate in the direction of winding the base portion 30. According to such a configuration, the base portion 30 in the deployed state is automatically wound up by the biasing force of the biasing member 23. Therefore, the labor of winding up the base portion 30 in the deployed state can be saved. Accordingly, the usability of the solar cell unit 11 is improved.

[0035] (1-4) The base portion 30 is provided with a locking portion 31 that detachably locks the base portion 30 in the deployed state to the clothing body 10. According to such a configuration, the base portion 30 in the deployed state is detachably locked to the clothing body 10 by the locking portion 31 provided separately from the support portion 20. Therefore, the base portion 30 in the deployed state can be stably held with respect to the clothing.

[0036] (1-5) The solar cell 40 is a perovskite solar cell. According to such a configuration, by using a flexible perovskite solar cell, the shape of the solar cell 40 can be easily deformed following the change in the shape of the base portion 30.

[0037] <Second Embodiment> Next, with reference to FIGS. 3 to 6, a second embodiment of the clothing with a solar cell will be described focusing on the differences from the first embodiment.

[0038] In the following, for the configurations of the second embodiment that are the same as or corresponding to the configurations of the first embodiment, the description may be omitted by attaching a reference numeral obtained by adding "50" to the reference numeral "**" of the configuration of the first embodiment.

[0039] In the present embodiment, the solar cell unit 61 is embodied as a so-called one-pole type blind curtain structure by the support portion 70 and the base portion 80. (Support portion 70) As shown in FIGS. 3 and 4, the support portion 70 includes a support portion main body 71, a pair of connecting strings 72, a through string 73, a first operation portion 77, and a second operation portion 78.

[0040] The support part main body 71 is in the shape of a rectangular tube, is located above the design surface 60a on the back surface of the clothing main body 60, and is adjacent to the design surface 60a. The support part main body 71 is attached to the clothing main body 60 via a bracket (not shown) fixed to the back surface of the clothing main body 60.

[0041] On the lower surface of the support part main body 71, a plurality of through holes 71a are provided at intervals in the left - right direction. In this embodiment, two through holes 71a are provided. Inside the support part main body 71, a winding mechanism 75 and an angle adjustment mechanism 76 are provided.

[0042] The winding mechanism 75 is constituted by a pulley rotatably attached to the support part main body 71. The angle adjustment mechanism 76 is constituted by a shaft portion extending along the left - right direction, a tilt mechanism that rotatably supports the shaft portion about the axis of the shaft portion, and a plurality of drums (all not shown) fixed to the shaft portion at intervals in the left - right direction.

[0043] The angle adjustment mechanism 76 protrudes outside the support part main body 71 and has an operation attachment part 76a that interlocks with the tilt mechanism. A cylindrical first operation part 77 is connected to the operation attachment part 76a.

[0044] As shown in FIG. 4, the pair of connecting strings 72 extend in the vertical direction and are arranged at intervals in the front - rear direction (left - right direction in FIG. 4) of the clothing main body 60. The pair of connecting strings 72 are respectively provided corresponding to the plurality of through holes 71a.

[0045] The upper ends of the pair of connecting strings 72 are connected to the angle adjustment mechanism 76 through the through holes 71a. The through string 73 extends from below the support part main body 71 through the through hole 71a into the support part main body 71 and then extends from inside the support part main body 71 into the first operation part 77. Inside the support part main body 71, the through string 73 is wound around the winding mechanism 75.

[0046] The through cords 73 are respectively provided corresponding to the plurality of through holes 71a. A second operation part 78 is connected to the end part on the first operation part 77 side of the through cord 73. (Base part 80) As shown in FIGS. 3 and 4, the base part 80 has a plurality of strip-shaped slats 85. The plurality of slats 85 are arranged side by side in the vertical direction.

[0047] The slat 85 is provided with a through hole 86 penetrating the slat 85 in the thickness direction of the slat 85. The plurality of through holes 86 are provided at positions corresponding to the plurality of through cords 73 respectively.

[0048] One end of the through cord 73 is connected to the slat 85B that constitutes the tip 80b of the base part 80 in the deployed state among the plurality of slats 85. The through cord 73 is loosely fitted in the other slats 85A except the slat 85B that constitutes the tip 80b.

[0049] As shown in FIG. 4, one ends 85a and the other ends 85b in the width direction of the plurality of slats 85 are respectively connected to a pair of connecting cords 72. On the lower surface of the slat 85B that constitutes the tip 80b of the base part 80, a locking part 81 for detachably locking the base part 80 in the deployed state to the clothing body 60 is provided. In the present embodiment, the locking part 81 is fixed to the lower surface of the slat 85B with an adhesive and is a hook-and-loop fastener that engages with the locked part 65 of the clothing body 60.

[0050] (Solar cell 90) As shown in FIG. 3, solar cells 90 are respectively attached to the upper surfaces of the plurality of slats 85. The solar cell 90 is located between two through holes 86 in the left-right direction.

[0051] As shown by the solid line in FIG. 4, in the unfolded state, a plurality of slats 85 are arranged along the back surface of the clothing body 60 and adjacent to each other in the width direction of the slats 85. At this time, the rear connecting string 72a of the pair of connecting strings 72 is drawn out from the angle adjusting mechanism 76, and the front connecting string 72b of the pair of connecting strings 72 is wound up by the angle adjusting mechanism 76. For this reason, the slats 85 are in an inclined posture such that the portion closer to one end 85a side of the slats 85 is positioned higher.

[0052] Also, by operating the pair of connecting strings 72 with the first operation portion 77, the inclination angle of the slats 85 with respect to the back surface of the clothing body 60 is changed. As shown by the two-dot chain line in FIG. 4, by rotating the first operation portion 77 about the axis L2 of the first operation portion 77, the rear connecting string 72a is wound up by the angle adjusting mechanism 76, and the front connecting string 72b is drawn out from the angle adjusting mechanism 76. As a result, the lengths of the connecting strings 72a and 72b extending below the support portion main body 71 become equal, so that the adjacent slats 85 are in a parallel posture in the vertical direction.

[0053] Also, as shown in FIGS. 5 and 6, by operating the through string 73 with the second operation portion 78, the interval between the slats 85 is adjusted. By pulling the second operation portion 78 downward in a state where the adjacent slats 85 are in a parallel posture in the vertical direction, the through string 73 extending below the support portion main body 71 is pulled toward the support portion main body 71. As a result, the portion between the adjacent slats 85 of the connecting string 72 is loosened, so that the adjacent slats 85 in the vertical direction approach the slats 85 positioned below in order. As a result, in the stored state, the plurality of slats 85 are in a posture intersecting the back surface of the clothing body 60 and overlap each other in the thickness direction of the slats 85.

[0054] <Operation and Effect of the Second Embodiment> According to the present embodiment, in addition to the operation and effects (1-1) and (1-4) of the first embodiment, the following operation and effects can be achieved.

[0055] (2-1) In the unfolded state, the plurality of slats 85 are arranged along the back surface of the clothing body 60 and adjacent to each other in the width direction of the slats 85. Further, in the stored state, the plurality of slats 85 are arranged to intersect the back surface of the clothing body 60 and overlap each other in the thickness direction of the slats 85.

[0056] According to such a configuration, since the solar cell unit 61 is composed of a plurality of strip-shaped slats 85, a pair of connecting strings 72, a penetrating string 73, a first operation portion 77, and a second operation portion 78, it has a so-called blind curtain structure. Thereby, even when the solar cell 90 does not have flexibility, the clothing with the solar cell can be realized.

In the first embodiment, when using a silicon - based solar cell, the width of the solar cell in the arrangement direction of the solar cells and the interval between the solar cells in the arrangement direction of the solar cells can be adjusted. Thereby, even in the case of a silicon - based solar cell with low flexibility, the base portion 30 can be wound by the shaft portion 21. Further, in the second embodiment, instead of a flexible solar cell, a silicon - based solar cell with low flexibility may be used.

[0059] · The locking portions 31, 81 may be omitted. ·In the second embodiment, the solar cell unit 61 is embodied as a one-pole type blind curtain structure in which the second operation unit 78 is arranged on the axis L2 of the first operation unit 77, but it is not limited thereto.
