DETAILED DESCRIPTION OF THE INVENTION

[0014] An embodiment of a panel clip for a slit-type sliding light-blocking curtain according to the present invention will be described below. The panel clip 5 of this embodiment is suitable for use on a ceiling 2 inside a greenhouse 1, which has a greenhouse framework made up of arch pipes 12 as shown in Figure 7, and has sheets fastened between sheet fastening materials (not shown), and is used in a slit-type sliding blackout curtain 3 that can slide horizontally as a blackout curtain with multiple solar panels 3 attached to it. However, the same can be done with a wooden house 9 as shown in Fig. 5. In addition, in the case of a house 9 with an oblique roof, the invention can also be applied to a blackout curtain 3 that is disposed obliquely parallel to the obliquely sloping roof, and the blackout curtain 3 can be slid obliquely to make effective use of the ceiling 2 of the house 9 (not shown). The multiple solar panels 3 are fixed to a rotating body 6 such as a bobbin attached to a drive pipe 7 provided on one side 10 inside the greenhouse 1, and a drive rope 4 wound around a rotating body 6 such as a pulley provided on the other side 11 (see Figure 5).

[0015] This is preferably implemented in a three-layered blackout curtain as shown in Figures 7 and 5, but there are no limitations on the number of layers. In the present embodiment, which is schematically shown in Figure 6, an example is shown in which a three-layered blackout curtain is implemented, and the solar panel 3 of the first layer, which is placed on the bottom layer, is not moved. The solar panel 3 of the second layer placed above it, and the solar panel 3 of the first layer placed above the second layer, are each slid to the desired positions.

[0016] The solar panels 3, which serve as blackout curtains, are each approximately 220 mm wide, 1700 mm deep, and 3 mm thick, and are arranged in three layers as described above. Nine solar panels 3 are arranged vertically in the direction of the frontage G (approximately 5.4 m) on each layer, for a total of 27 panels in three layers. These three layers of 27 panels are arranged in six groups in the direction of the depth T (approximately 10 m), for a total of 162 solar panels 3 (Figure 7). The solar panels 3 are attached to a drive rope 4 with a gap (slit) of about 400 mm between them in the direction of the opening G (see Figure 7). One end 40 and the other end 41 of the drive rope 4 are fixed to a rotor 6, which rotates to move the drive rope 4 within a desired range in the direction of the opening G. In this embodiment, as shown below, an example is described in which a solar panel 3 is used as a shading curtain, but the same can be applied to a shading sheet or shading sheet panel (not shown) instead of the solar panel 3.

[0017] This panel clip 3 is made up of a set of a clamping body 5A on one side (for example, the upper side) and a clamping body 5B on the other side (for example, the lower side), and one-side clamping body 5A is provided with one or more (preferably two) protrusions 51 with locking portions 51a protruding vertically, and protrusions 51 of one-side clamping body 5A can be locked to the inside (explained below) or side (explanation omitted) of the other-side clamping body 5B. Then, with a drive rope 4 disposed and clamped between the one-side clamping body 5A and the other-side clamping body 5B, clamping ends 52, 57 of the one-side clamping body 5A and the other-side clamping body 5B clamp end 30 of the solar panel (light-blocking curtain) 3, and the solar panel 3 is fixed to the drive rope 4.

[0018] The panel clip 5 of this embodiment shown in Figures 1 and 2 is an example in which one side clamping body 5A is an upper clamping body and the other side clamping body 5B is a lower clamping body, and this will be described in detail below. This panel clip 5 is made of resin and is composed of an upper one-side clamping body 5A shown in Fig. 1 and a lower other-side clamping body 5B shown in Fig. 2. However, the material of the panel clip 5 is not limited to resin, and it may be made of, for example, iron or the like. As shown in Figures 3 and 4, both the upper clamping body 5A and the lower clamping body 5B are configured to clamp the end 30 of the solar panel 3 and to be able to fix it while clamping the drive rope 4.

[0019] The upper one-side clamping body 5A is formed of a plate-like body approximately 37 mm long, approximately 30 mm wide, and approximately 5 mm thick, and on its underside 50 there are provided two protrusions 51, each approximately 2 to 3 mm thick and protruding approximately 20 mm downward in the vertical direction, spaced approximately 13 mm apart and arranged horizontally in the direction of the drive rope 4. The outer surface of this protrusion 51 is provided with a slightly raised locking portion 51a so as to lock into an insertion hole 56 of the lower other-side clamping body 5B, which will be described later. 1C, a linear protrusion 53 (having a length of about 23 mm) is provided at approximately the center of the lower surface 50 of the upper clamping body 5A at a position corresponding to the groove 58 of the other-side clamping body 5B, which will be described later, by pressing from above to fix the drive rope 4 that fits into the groove 58 (see FIG. 2A) of the other-side clamping body 5B. Small protrusions 53a for preventing slippage are provided on the side of this linear protrusion 53. As shown in Figure 1C, the inner surface of the clamping end 52 of the one-side clamping body 5A is cut out by the thickness K (in this embodiment, K is approximately 3 mm) of the end of the solar panel 3 to be clamped, forming a stepped recessed end 54. However, an embodiment in which this stepped end 54 is formed on the clamping end 57 of the other clamping body 5B can also be employed (not shown).

[0020] 2A, 2B, 2C, 2D, and 2F, the lower other clamping body 5B is formed of a plate-like body about 37 mm long, about 30 mm wide, and about 5 mm thick, and is provided with two insertion holes 56 at positions corresponding to the two protrusions 51 of the upper clamping body 5A, into which the protrusions 51 can be freely fitted. In this embodiment, the insertion holes 56 and the protrusions 51 are provided on the upper surface 55 of the lower clamping body 5B and the lower surface 50 of the upper clamping end 5A, excluding the clamping ends 57 and 52, respectively. 2A and 2B, a groove 58 (having a length of about 37 mm, a width of about 2 mm, and a depth of about 2 mm) into which the drive rope 4 fits is formed in the longitudinal direction of the center of the upper surface 55 of the lower clamping body 5B, and the drive rope 4 sandwiched between the linear protrusion 53 of the upper one-side clamping body 5A fits into the groove 58, so that the upper and lower clamping bodies 5A and 5B can be freely fixed to the drive rope 4. The inner wall of the groove 58 of the lower clamping body 5B is provided with a protrusion 59 for preventing slippage, which positions and fixes the drive rope 4 that fits into the groove 58, ensuring that the drive rope 4 is securely fixed (Figure 2A).

[0021] Therefore, with the drive rope 4 placed in the groove 58 of the lower clamping part 5B between the two protrusions 51 of the upper clamping body 5A and the protrusion 51 fitted into the insertion hole 56, the step ends 54 of the clamping ends 52 of the upper and lower clamping bodies 5A and the clamping end 57 of the lower clamping body 5B clamp the end 30 of the solar panel 3, and the solar panel 3 is firmly fixed to the drive rope 4, as shown in Figures 3 and 4.

[0022] Thus, as shown in Fig. 6A, when the solar panels 3 (shading curtains) are fully open with all first to third layers positioned at the same position, sunlight S is irradiated onto the plants in the greenhouse 1. When the solar panels 3 are in this fully open state, the rotating body 6 is rotated forward, allowing the solar panels 3 fixed by the panel clips 5 to slide freely (see Fig. 6B). Therefore, the drive ropes 4 slide in the directions indicated by the symbols P1 and P2 so that the overlapping width W of the upper and lower solar panels 3 on each layer 1, 2, and 3 is approximately 18 mm, as shown in Figures 6B and 7A. In this state, each solar panel 3 receives sufficient light from the sun S, allowing for maximum storage and use of solar power generation energy. Then, when the rotor 6 is rotated in the reverse direction, each solar panel 3 slides in the reverse direction and returns to its original position in the fully open state as shown in FIG. 6A.

[0023] As a different embodiment, the upper one-side clamping body 5A and the lower other-side clamping body 5B may be reversed (not shown). That is, the upper surface (55) of the lower other clamping body 5B that constitutes the panel clip 5 is provided with two protrusions (51) with locking portions (51a) that protrude upward, and the upper clamping body 5A is provided with two insertion holes (56) at corresponding positions to the protrusions (51) of the lower clamping body 5B, into which the protrusions (51) can be freely fitted.It is also possible to adopt a configuration in which, with the drive rope 4 positioned between the two protrusions (51) of the lower clamping body 5B, the clamping ends (54, 57) of the upper and lower clamping bodies 5A, 5B clamp the end 30 of the solar panel 3, and the solar panel 3 is fixed to the drive rope 4.

[0024] The above describes the embodiments based on the drawings. However, it should be noted that the present invention is not limited to the illustrated examples, and includes the range of design modifications and application variations that are normally made by those skilled in the art, provided that they do not deviate from the technical concept of the present invention.
