  As shown in FIG. 4, the vehicle roof shade device 1 includes a support member 6 that is attached to the vehicle body 2 and supports the daylighting roof shade 3 and the light shielding roof shade 4 so as to be slidable in the front-rear direction. The support member 6 includes a pair of front and rear extending members 6a extending along the front-rear direction in parallel with each other on both sides in the vehicle width direction, and a plurality of left and right extending members 6b extending substantially along the vehicle width direction. Configured. In FIG. 4, only the left and right extending members 6b are shown along the front edge of the opening 2b. In the present embodiment, a substantially rectangular frame portion (not shown) surrounding the periphery of the opening 2b is formed by the front / rear extending member 6a and the left / right extending member 6b.

  As shown in FIG. 5, a concave groove 6 c that extends in the front-rear direction and opens toward the inner side in the vehicle width direction is formed on the side surface on the inner side in the vehicle width direction of each front-rear extending member 6 a. And in this concave groove 6c, the vehicle width of the protrusion 3a projectingly provided at both ends in the vehicle width direction of the daylighting roof shade 3 and the tip member 4a disposed at the leading end of the light shielding roof shade 4 is provided. Projection portions 4b projecting at both ends in the direction are inserted so as to be slidable back and forth. That is, in this embodiment, the concave groove 6c serves as a guide portion that guides the daylighting roof shade 3 and the light shielding roof shade 4 so as to be slidable back and forth, and the protruding portions 3a and 4b are guided by the guide portion. Part. The concave groove 6c as the guide portion is shared by both the protruding portions 3a and 4b as the guided portions.

  The daylighting roof shade 3 is configured as a slide door that closes the opening 2b so as to be openable and closable. As shown in FIG. 6, a sheet-like daylighting member 7 that substantially extends along the passenger compartment ceiling 2a, and an upper side of the daylighting member 7. A frame 8 as a reinforcing member, a cover frame 9 disposed below the daylighting member 7, and a double-sided tape 10 that fixes the daylighting member 7 to the frame 8.

  As shown in FIG. 7, the daylighting member 7 is sandwiched between a transparent sheet 7a made of a synthetic resin such as PET resin disposed on the front and back sides (upper and lower sides) and the transparent sheets 7a and 7a on both sides of the front and back sides. And a non-woven fabric layer 7b as a light control layer, and these are integrated by bonding or the like. In the daylighting member 7, the non-woven fabric layer 7b can provide a blocking function and a daylighting function. The transparent sheets 7a and 7a function as a protective layer for the nonwoven fabric layer 7b, suppress the nonwoven fabric layer 7b from sagging, and give the lighting member 7 the required rigidity. Instead of the non-woven fabric layer 7b, a paper layer made of Japanese paper, Western paper, or the like, or a layer in which non-woven fabric and paper are mixed may be provided. Further, in this daylighting member 7, the non-woven fabric layer 7b (or paper layer or mixed layer) is intentionally formed unevenly in the surface, or a pattern or a pattern is applied to this layer, thereby improving the design. Is possible.

  The frame 8 is configured by integrally joining a plurality of metal members such as aluminum alloy rectangular pipes by welding or the like, and is formed on the peripheral portion of the daylighting roof shade 3 substantially along the cabin ceiling 2a. A substantially rectangular peripheral frame 8a to be arranged, and two erection frames 8b erected between the left and right peripheral frames 8a with a space in the front-rear direction.

  Here, in the present embodiment, the erection frame 8b has a bent shape substantially along the passenger compartment ceiling 2a. Specifically, in the present embodiment, the center portion 8f in the vehicle width direction of the erection frame 8b is bulged in a curved shape toward the rear. Thereby, the rigidity (torsional rigidity and bending rigidity) of the installation frame 8b, and consequently the rigidity (torsional rigidity and bending rigidity) of the frame 8 can be increased. Note that the peripheral frame 8a at the front and rear ends has the same shape and has the same effect.

  The cover frame 9 is formed by molding a synthetic resin material such as PP resin or ABS resin, and has a shape substantially along the frame 8 in plan view as shown in FIGS. . However, as shown in FIGS. 8 to 10, each part of the cover frame 9 is formed wider than the frame 8 so as to cover the frame 8 from the lower side (vehicle interior side). Moreover, in this embodiment, the design property is improved by forming the two installation parts 9a of the cover frame 9 together with the two installation frames 8b of the frame 8 into a curved shape by smoothly bending them.

  In the present embodiment, the daylighting member 7 and the cover frame 9 are both fixed to the frame 8. Specifically, as shown in FIGS. 6 and 10, the daylighting member 7 is joined to the lower surface of the frame 8 with a strip-like double-sided tape 10 having a desired thickness and flexibility. Further, the cover frame 9 is formed with a plurality of protrusions 9b protruding upward and having female screw holes 9c at the top, and each of the protrusions 9b is formed on the lighting member 7 as shown in FIGS. A through-hole 7c is formed at a position overlapping with. Furthermore, a through-hole 8d that penetrates the protruding portion 9b is formed in the lower wall 8c of the frame 8, and a through-hole 8g through which the screw 14 is inserted is formed in the upper wall 8e. Then, with such a configuration, the protruding portion 9b is passed through the through-hole 7c of the daylighting member 7 and the through-hole 8d of the lower wall 8c of the frame 8 from below, the top of the protruding portion 9b is abutted against the upper wall 8e, A screw 14 penetrated from above through a through hole 8g formed in the upper wall 8e is screwed into a female screw hole 9c formed in the protruding portion 9b. That is, in this embodiment, the screw 8 is screwed into the female screw hole 9c of the cover frame 9, whereby the frame 8 and the cover frame 9 are coupled. In such a configuration, the thickness of the double-sided tape 10 is slightly larger than the height of the gap between the daylighting member 7 and the lower surface of the frame 8, so that the double-sided tape 10 is slightly compressed into the gap. The daylighting member 7 can be sandwiched between the frame 8 and the cover frame 9 while providing an appropriate force by the elastic force of the double-sided tape 10. However, the daylighting member 7 is not coupled to the cover frame 9. That is, the daylighting member 7 is slidable in the lateral direction (the direction along the passenger compartment ceiling 2a) with respect to the cover frame 9.

  The light-shielding roof shade 4 is configured as a screen that is rewound into and out of the winding unit 11. As shown in FIGS. 1 and 4, the winding unit 11 is disposed in front of the opening 2 b and includes a rotating shaft 12 that extends along the vehicle width direction. The rotation shaft 12 is rotatably supported by the support member 6, and can wind up the shading roof shade 4 as a screen so that it can be taken in and out.

  As shown in FIG. 11, both ends 4c in the width direction of the light-shielding roof shade 4 (the direction orthogonal to the moving direction, in the present embodiment, the vehicle width direction) are folded and bonded or stitched inward. Thus, a double thick portion 4d is formed. On the other hand, on the back side of the concave groove 6c of the support member 6 (that is, the outer side in the vehicle width direction, the right side in FIG. 11), a concave groove 6d that accommodates the thick portion 4d is formed, and the concave groove 6c and the concave groove 6d are formed. A wall portion 6e that protrudes in the up-down direction (downward in the present embodiment) and extends in the front-rear direction is formed at the boundary portion. The wall portion 6e extends along both end portions 4c in the width direction (vehicle width direction) orthogonal to the moving direction (front-rear direction) of the light-shielding roof shade 4 in the pair of left and right front-rear extending members 6a, 6a of the support member 6. It is extended. With this configuration, when the light-shielding roof shade 4 moves while being guided by the concave groove 6c, the wall portion 6e locks the thick-walled portion 4d (the stepped portion formed by the end portion 4c). The roof shade 4 is restricted from moving inward in the width direction (vehicle width direction). Thereby, tension can be given to the light-shielding roof shade 4 to suppress wrinkles and slack.

  However, when the shading roof shade 4 having such a thick portion 4d is wound around the rotating shaft 12, the outer diameter of the portion where the thick portion 4d is wound is a general portion other than the thick portion 4d. It becomes larger than the outer diameter of the part wound up (intermediate part in the width direction). For this reason, in the state in which the light-shielding roof shade 4 is pulled out by the rotating shaft 12 and is pulled out (that is, not fully pulled out), the tension in the intermediate portion in the width direction is weakened, and the drawer is pulled out. There is a risk of slack in the direction (winding direction, front-rear direction in this embodiment).

  Therefore, in the present embodiment, as shown in FIG. 4, the intermediate portion 12 a in the rotation axis direction of the rotation shaft 12 (vehicle width direction in the present embodiment) is compared with both end portions 12 b in the rotation axis direction. In order to increase the diameter, a sponge-like flexible member 13 covering the outer periphery of the rotating shaft 12 is provided. That is, in the present embodiment, the flexible member 13 corresponds to the enlarged diameter portion.

  Therefore, as shown in FIGS. 12A and 12B, in the state where the light-shielding roof shade 4 is wound about half, the intermediate portion in the rotational axis direction is provided by the amount of the flexible member 13 provided. The winding diameter (outer diameter) Dm at the end is substantially the same as the winding diameter (outer diameter) De at the end in the rotational axis direction, thereby suppressing the occurrence of slack in the light-shielding roof shade 4. Can do.

  Note that the thickness t of the flexible member 13 (see FIG. 12C) is the state in which the light-shielding roof shade 4 is wound more than half, that is, the tip member 4a of the light-shielding roof shade 4 in FIG. The winding diameters Dm and De are set to the same value in a state in any position within the region Ar on the winding side (front side in the present embodiment) from the intermediate position Pm of the moving section in the front-rear direction. It is preferable to set.

  Further, in the present embodiment, as shown in FIG. 12C, a flexible member 13 as a diameter-expanded portion is attached to the rotating shaft 12 after the light-shielding roof shade 4 is attached. If the flexible member 13 is attached to the rotating shaft 12 first, it becomes difficult to attach the light-shielding roof shade 4 as a screen to the rotating shaft 12, and a step is generated in the attaching portion. It becomes difficult to stretch evenly along, causing wrinkles and slack. According to the present embodiment, since the flexible member 13 is attached in a state where the light-shielding roof shade 4 is fully pulled out after the light-shielding roof shade 4 is attached to the rotating shaft 12, such a problem is suppressed. be able to.

  As described above, in the present embodiment, the daylighting roof shade 3 as the vehicle roof shade is divided into the sheet-like daylighting member 7, the peripheral frame 8 a disposed at the peripheral edge of the daylighting roof shade 3, and the left and right sides. And a frame 8 as a reinforcing member having an erection frame 8b erected between the peripheral frames 8a. The erection frame 8b has a bent shape substantially along the passenger compartment ceiling 2a. Accordingly, the daylighting roof shade 3 can be configured to be lighter by the provision of the sheet-shaped daylighting member 7, and the required rigidity can be ensured by the frame 8 including the installation frame 8b that is bent to increase the rigidity. .

  Further, in the present embodiment, the frame 8 is formed of a metal member and is disposed on the upper side of the daylighting member 7, and a cover frame 9 that is configured of a resin member and covers the frame 8 from the lower side is provided below the daylighting member 7. The provided lighting member 7 was coupled to only the frame 8 of the frame 8 and the cover frame 9. When the sheet-shaped daylighting member 7 is coupled to the cover frame 9 made of a resin member, the resin member has a relatively large linear expansion coefficient. Therefore, the change in the tension of the daylighting member 7 due to the expansion and contraction of the cover frame 9 due to a temperature change. Becomes larger, and wrinkles and slack are likely to occur in the daylighting member 7. In this respect, according to the present embodiment, the daylighting member 7 is coupled to the frame 8 made of a metal member having a smaller linear expansion coefficient than that of the resin member, so that wrinkles and slack occur in the sheet-like daylighting member 7. It becomes easy to suppress. Moreover, it becomes easy to improve aesthetics by arrange | positioning the cover frame 9 in the lower side, ie, vehicle interior side, and covering the flame | frame 8. FIG.

  Moreover, in this embodiment, the lighting member 7 was couple | bonded with the flame | frame 8 via the double-sided tape 10 as a member which has flexibility. Therefore, the double-faced tape 10 can absorb the difference in deformation amount due to the temperature change between the frame 8 and the daylighting member 7, thereby further suppressing the occurrence of wrinkles and slack in the sheet-like daylighting member 7. It becomes easy to do.

  In the present embodiment, the daylighting member 7 includes the transparent sheets 7a and 7a disposed on the front and back sides, and the nonwoven fabric layer 7b as a light control layer sandwiched between the transparent sheets 7a and 7a on the front and back sides, Have Therefore, since the rigidity of the daylighting member 7 can be ensured by the transparent sheet 7a and the light control function can be ensured by the nonwoven fabric layer 7b, both rigidity and light control can be achieved relatively easily.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. In the above embodiment, the erection frame is bulged backward in a curved shape, but this may be bulged forward or bent to other shapes such as a polygonal line shape, a saw blade shape, a crank shape, etc. Is also possible. Further, a construction frame may be provided between the front and rear peripheral frames, and this may be bent.

  Moreover, in the said embodiment, although the double-sided tape 10 was used as a member which has flexibility, a flexible member other than a double-sided tape is interposed between the lighting member 7 and the flame | frame 8, and the lighting member 7 and the flame | frame 8 are interposed. It is also possible to bond the daylighting member 7 and the frame 8 to each other via the flexible member by bonding both of them to the flexible member by bonding or the like.

  Moreover, a film etc. can be used for a light control layer other than a nonwoven fabric and paper. In this case, for example, a colored transparent film can be arranged in an appropriate shape to form a stained glass.
