Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above prior art, near the ends of each shade guide rail, the side edges of the shade are guided by the multifunctional stopper. On the other hand, between each shade guide rail and the winding shaft, the side edges of the shade are not guided at all. Therefore, when the shade is wound around the winding shaft, there is a risk that winding wrinkles will occur on the shade due to the side edges of the shade moving in the left-right direction.

[0005] In view of the above background, an object of the present invention is to provide a sunshade device capable of suppressing the occurrence of winding wrinkles on the shade sheet.

Means for Solving the Problems

[0006] In order to solve the above problems, an aspect of the present invention is a sunshade device (1), which includes a shade sheet (3), left and right guide bands (4) provided along both side edges (3A) of the shade sheet, left and right guide rails (5) for guiding the left and right guide bands in their longitudinal directions, a cross member (6) connecting the left and right guide rails, a winding shaft (7) supported by the cross member at a position spaced apart from the left and right guide rails for winding the shade sheet, and left and right first guide blocks (8) attached to the cross member between the left and right guide rails and the winding shaft for guiding the left and right guide bands.

[0007] According to this aspect, between each guide rail and the winding shaft, the guide band can be guided by the first guide block. Thereby, the lateral movement of the guide band can be restricted, and the occurrence of winding wrinkles in the shade sheet can be suppressed.

[0008] In the above aspect, the cross member may include an engagement hole (20) having a rectangular contour shape, each first guide block may include an engagement portion (26) having a rectangular cross-sectional shape, and in a state where each first guide block is attached to the cross member, the engagement portion may engage with the engagement hole.

[0009] According to this aspect, the rotation of each first guide block with respect to the cross member can be suppressed with a simple configuration.

[0010] In the above aspect, a convex portion (21) for defining the attachment direction of each first guide block with respect to the cross member may be provided on the outer edge portion of the engagement hole, a protrusion portion (41) may be provided at a position corresponding to the convex portion on the outer surface of the engagement portion, and in a state where each first guide block is attached to the cross member, the protrusion portion may engage with the convex portion.

[0011] According to this aspect, by using the protrusions and the convex portions as marks, it is possible to confirm the correct attachment orientation of each first guide block to the cross member. Therefore, it is possible to prevent an operator from attaching each first guide block to the cross member in the wrong orientation, and it is possible to shorten the attachment time of each first guide block to the cross member.

[0012] In the above aspect, the engaging portion includes an elastically deformable hook (46), and in a state where each first guide block is attached to the cross member, the hook engages with the cross member, so that the removal of each first guide block from the cross member may be restricted.

[0013] According to this aspect, it is possible to restrict the removal of each first guide block from the cross member with a simple configuration. Further, by elastically deforming the hook, it is possible to easily remove each first guide block from the cross member. Therefore, when each first guide block is damaged or the like, each first guide block can be easily replaced.

[0014] In the above aspect, each first guide block may be provided at a position separated from the guide rail.

[0015] According to this aspect, the distance between each first guide block and the winding shaft can be shortened. Therefore, the guide belt can be guided by each first guide block at a position close to the winding shaft. Thereby, the lateral movement of the guide belt can be effectively restricted, and the occurrence of winding wrinkles in the shade sheet can be effectively suppressed.

[0016] In the above aspect, in a plan view, the distance (D1) between each first guide block and the winding shaft may be shorter than the distance (D2) between each first guide block and the guide rail.

[0017] According to this aspect, each first guide block can guide the guide belt at a position closer to the winding shaft. Thereby, the movement of the guide belt in the left - right direction can be more effectively restricted, and the generation of winding wrinkles on the shade sheet can be more effectively suppressed.

[0018] In the above - mentioned aspect, the sunshade device may further include left - and - right second guide blocks (9) that are connected to the ends of the left - and - right guide rails on the winding - shaft side and guide the guide belt.

[0019] According to this aspect, it is possible to prevent the shade sheet from contacting the end of the guide rail on the winding - shaft side. Thereby, damage to the shade sheet can be prevented.

[0020] In the above - mentioned aspect, each first guide block is provided with a first guide groove (28) with which the guide belt engages, and each second guide block is provided with a second guide groove (58) with which the guide belt engages. The angle of the portion of the guide belt that engages with the second guide groove with respect to the horizontal direction may be different from the angle of the portion of the guide belt that engages with the first guide groove with respect to the horizontal direction.

[0021] According to this aspect, each first guide block and each second guide block can hold the guide belt at an appropriate angle. Thereby, the generation of winding wrinkles on the shade sheet can be more effectively suppressed.

Effect of the Invention

[0022] According to the above aspects, it is possible to provide a sunshade device capable of suppressing the generation of winding wrinkles on the shade sheet.

[0034] Referring to FIG. 4, engaging holes 20 are provided on both the left and right sides of the cross member 6 (only the right side is shown in FIG. 4). Each engaging hole 20 penetrates from the upper surface to the lower surface of the cross member 6. Each engaging hole 20 has a rectangular contour shape. Here, the "rectangular contour shape" includes not only a completely rectangular contour shape but also a substantially rectangular contour shape including small irregularities. On the inner edge in the left-right direction of the engaging hole 20 (an example of the outer edge of the engaging hole 20), a convex portion 21 for defining the mounting direction of the first guide block 8 with respect to the cross member 6 protrudes inward in the left-right direction.

[0035] Referring to FIGS. 1 and 2, the winding shaft 7 extends in the left-right direction. The longitudinal base end portion of the shade sheet 3 is attached to the winding shaft 7. The winding shaft 7 is rotatably supported by the cross member 6. The winding shaft 7 is biased in the rotational direction for winding the shade sheet 3 by the retractor 23.

[0036] Referring to FIG. 5, each first guide block 8 is provided at a position spaced apart from the guide rail 5 and the winding shaft 7. In a plan view, the distance D1 between each first guide block 8 and the winding shaft 7 is shorter than the distance D2 between each first guide block 8 and the guide rail 5.

[0037] Referring to FIGS. 6 to 8, each first guide block 8 is made of, for example, resin. Each first guide block 8 includes a block body 25 and an engaging portion 26 protruding downward from the lower surface of the block body 25. The block body 25 and the engaging portion 26 are integrally formed.

[0038] On the upper part of the block body 25, a first guide groove 28 is provided. The first guide groove 28 extends continuously from the front surface to the rear surface of the block body 25 along the front-rear direction (the longitudinal direction of the shade sheet 3). The guide strip 4 and the side edge 3A of the shade sheet 3 are engaged with the first guide groove 28. At the central portion in the left-right direction of the first guide groove 28, a first communication port 29 for passing the shade sheet 3 opens upward.

The second guide groove 58 extends continuously from the front surface to the rear surface of the guide portion 52. The side edges 3A of the guide band 4 and the shade sheet 3 are engaged with the second guide groove 58. The angle of the portion of the guide band 4 engaged with the second guide groove 58 with respect to the horizontal direction is different from the angle of the portion of the guide band 4 engaged with the first guide groove 28 (see FIG. 6) with respect to the horizontal direction. More specifically, the angle of the portion of the guide band 4 engaged with the second guide groove 58 with respect to the horizontal direction is larger than the angle of the portion of the guide band 4 engaged with the first guide groove 28 with respect to the horizontal direction. A second communication port 59 for passing the shade sheet 3 therethrough opens inward in the left - right direction at the center in the left - right direction of the second guide groove 58. A pair of second locking surfaces 60 are provided on the inner and outer sides in the left - right direction of the second communication port 59 in the second guide groove 58. The second locking surface 60 provided on the inner side in the left - right direction of the second communication port 59 locks the inner portion in the left - right direction of the guide band 4. The second locking surface 60 provided on the outer side in the left - right direction of the second communication port 59 locks the side edge 3A of the shade sheet 3.

[0048] Referring to FIG. 3, the insertion portion 55 is substantially L - shaped. The insertion portion 55 extends along the front - rear direction (the longitudinal direction of the shade sheet 3). The insertion portion 55 is inserted into the rear end portion (the end portion on the winding shaft 7 side) of the insertion groove 17 of the guide rail 5.

[0049] Next, the winding / unwinding operation of the shade sheet 3 in the sunshade device 1 configured as described above will be described.

[0050] When the crossbar 11 is moved rearward by the electric motor, the shade sheet 3 is wound around the winding shaft 7 by the biasing force of the retractor 23, and the shade sheet 3 is in the wound state (see FIG. 1). On the other hand, when the crossbar 11 is moved forward by the electric motor, the shade sheet 3 is pulled out from the winding shaft 7 against the biasing force of the retractor 23, and the shade sheet 3 is in the deployed state (see FIG. 2).

[0051] When the side edge 3A of the shade sheet 3 moves in the left - right direction between each guide rail 5 and the winding shaft 7 as the shade sheet 3 is wound around the winding shaft 7 as described above, there is a possibility that winding wrinkles will occur in the shade sheet 3. Therefore, in the present embodiment, between each guide rail 5 and the winding shaft 7, the guide belt 4 is guided by the first guide block 8. Thereby, the left - right movement of the guide belt 4 is restricted, and the occurrence of winding wrinkles in the shade sheet 3 can be suppressed.

[0052] Next, the attachment operation of the first guide block 8 to the cross member 6 in the sunshade device 1 configured as described above will be described.

[0053] Referring to FIG. 10(A), first, the operator engages the engaging portion 26 of the first guide block 8 with the engaging hole 20 of the cross member 6 from above. Thereby, the first inclined surface 47 of each hook 46 abuts (engages) against the portion around the engaging hole 20 of the cross member 6.

[0054] Referring to FIG. 10(B), next, the operator presses the first guide block 8 from above. Thereby, the portion around the engaging hole 20 of the cross member 6 presses each hook 46 inward in the front - rear direction, and each hook 46 elastically deforms inward in the front - rear direction.

[0055] Referring to FIG. 10(C), next, the operator further presses the first guide block 8 from above. As a result, the pressing of each hook 46 inward in the front-rear direction by the portion around the engaging hole 20 in the cross member 6 is released, and each hook 46 elastically returns outward in the front-rear direction. Thereby, the first guide block 8 is attached to the cross member 6.

[0056] In the state where the first guide block 8 is attached to the cross member 6 in this way, the second inclined surface 48 of each hook 46 abuts (engages) against the portion around the engaging hole 20 in the cross member 6. Thereby, the removal of the first guide block 8 from the cross member 6 is restricted. Further, the upper surface of the cross member 6 abuts against the lower surface of the block body 25 (including the projecting piece 32), and the projecting portion 41 of the engaging portion 26 engages with the convex portion 21 of the engaging hole 20.

[0057] When removing the first guide block 8 from the cross member 6, the operator lifts the first guide block 8 with respect to the cross member 6 in a state where each hook 46 is elastically deformed inward in the front-rear direction. Thereby, the engagement of the engaging portion 26 with the engaging hole 20 is released, and the first guide block 8 is removed from the cross member 6. In this way, by elastically deforming each hook 46, the first guide block 8 can be easily removed from the cross member 6. Therefore, when the first guide block 8 is damaged or the like, the first guide block 8 can be easily replaced.

[0058] In the above embodiment, the distance D1 between each first guide block 8 and the winding shaft 7 is shorter than the distance D2 between each first guide block 8 and the guide rail 5. In other embodiments, the distance D1 between each first guide block 8 and the winding shaft 7 may be equal to or greater than the distance D2 between each first guide block 8 and the guide rail 5.

[0059] In the above embodiment, the angle with respect to the horizontal direction of the portion of the guide strip 4 that engages with the second guide groove 58 is larger than the angle with respect to the horizontal direction of the portion of the guide strip 4 that engages with the first guide groove 28. In other embodiments, the angle with respect to the horizontal direction of the portion of the guide strip 4 that engages with the second guide groove 58 may be smaller than the angle with respect to the horizontal direction of the portion of the guide strip 4 that engages with the first guide groove 28, or may be the same as the angle with respect to the horizontal direction of the portion of the guide strip 4 that engages with the first guide groove 28.

[0060] In the above embodiment, the window panel is fixed to the opening provided in the outer panel of the roof. In other embodiments, a movable window panel may be provided in the opening provided in the outer panel of the roof.

[0061] In the above embodiment, the window panel is fixed to the outer panel of the roof, and the sunshade device 1 is fixed to the inner panel of the roof. In other embodiments, the sunshade device 1 may be directly fixed to the window panel.

[0062] In the above embodiment, the winding shaft 7 is supported by the rear cross member 6, and the left and right first guide blocks 8 and the left and right second guide blocks 9 are attached to the rear cross member 6. In other embodiments, the winding shaft 7 may be supported by the front cross member 6, and the left and right first guide blocks 8 and the left and right second guide blocks 9 may be attached to the front cross member 6. That is, in other embodiments, the front-rear relationship of each component of the sunshade device 1 may be reversed from that of this embodiment.

[0063] With the above, the description of the specific embodiments ends. However, the present invention is not limited to the above embodiments and modifications, and can be widely modified and implemented. For example, the specific configurations, arrangements, quantities, materials, procedures, etc. of each member and part described in the above embodiments can be appropriately changed as long as they do not deviate from the gist of the present invention. On the other hand, not all of the components shown in the above embodiments are necessarily essential, and can be appropriately selected.
