FIG. 10 is a rear view of FIG. FIG. 4 is an enlarged perspective view of the main part of the sunshade device, and FIG. 5 is an explanatory view showing a state in which the light shielding plate (molded plate) rotates as it is pulled out.

  As shown in FIG. 1, a package tray 3 is disposed at the rear upper part of the rear seat 2 of the vehicle 1, and a sunshade device 10 is installed at the rear of the package tray 3. As shown in FIGS. 2 and 3, the sunshade device 10 includes a curtain body (shade) 12 made of a flexible sheet-like member, and the curtain body 12 is disposed on the surface of the rear window W on the vehicle interior side. The vehicle interior side of the rear window W of the vehicle 1 can be covered by deploying along As the sheet-like member constituting the curtain 12, for example, a translucent sheet, an opaque sheet, a mesh sheet, a woven fabric, a non-woven fabric, or the like can be used. As a material for such a sheet-like member, for example, a synthetic resin material such as polyvinyl chloride or polypropylene can be used.

Further, the sunshade device 10 includes a shaft 14 for winding the curtain body 12 and a case 16 for housing the shaft 14.
The shaft 14 is configured by a cylindrical member capable of winding the curtain body 12 around it. The shaft 14 is made of a synthetic resin material such as polypropylene, or a metal material such as aluminum or iron. Inside the shaft 14, a coil spring (not shown) for urging the curtain body 12 in the direction to be wound inside the case 16 is incorporated.
The case 16 is configured by a rectangular tube-like member that can accommodate the shaft 14 in a rotatable state. The case 16 is made of, for example, a synthetic resin material such as polypropylene, or a metal material such as aluminum or iron. On the upper side of the case 16, an opening 18 for drawing the curtain 12 upward is provided.

  A light shielding plate (molded plate) 20 made of a long plate-like member is attached to the upper end portion of the curtain body 12. The light shielding plate 20 is made of, for example, a synthetic resin material such as polypropylene, or a metal material such as aluminum or iron, and facilitates drawing of the curtain body 12 and is a frame that is unfolded and supported above the rear window W. The upper side portion 20a is formed in an arc shape so as to extend along the vehicle interior ceiling surface R in order to fulfill the role of In the present embodiment, along with the operation of pulling out the light shielding plate 20, the curtain body 12 made of a flexible member can be expanded along the rear window W.

  A pair of support members 22 made of long columnar members (bar-shaped members) are attached to the left and right ends of the light shielding plate 20, respectively. The support member 22 supports the light shielding plate 20 and is composed of a columnar member (columnar member here) whose axial cross-sectional shape is substantially the same along the longitudinal direction, and a protrusion (projection) 51 is fitted and fixed on the surface thereof. A possible perforation 50 (which may be screwed) is provided. One end of each support member 22 is inserted into insertion holes 21 formed at both left and right ends of the light shielding plate 20, and the other end is integrated with a slider 24 attached to the guide rails 26a and 26b. In this embodiment, the support member 22 is positioned and fixed with respect to the slider 24, that is, attached in a state in which the shaft cannot be rotated.

  On both sides of the rear window W, a pair of guide rails 26a and 26b made of a long member having a substantially U-shaped axial section is attached. The pair of guide rails 26a, 26b is formed of, for example, a metal material such as iron or aluminum, and is disposed along both sides of the rear window W. Further, the slider 24 described above is slidably fitted inside each of the pair of guide rails 26a and 26b so as to be slidable in the vertical direction, whereby the slider 24 (supporting member 22), and by extension, the light shielding plate 20 is thus fitted. Are guided in the pull-out direction. The guide rails 26a and 26b are linear in the sliding direction of the slider 24, that is, the drawing direction of the light shielding plate 20, and further, the guide rails 26a and 26b are closer to each other along the drawing direction of the light shielding plate 20. It is arranged so as to be inclined inward in the vehicle width direction.

  As shown in FIG. 4, the insertion hole 21 formed in the light shielding plate 20 has a hole shaft cross-sectional shape (here circular) corresponding to (similar to) the shaft cross-sectional shape of the support member 22. It is possible to insert the shaft 22 without shaking the shaft. Further, the insertion hole 21 is formed with a hole 60 having a shape in which a wall part forming the hole is cut out, and the hole 60 can be fitted to the protrusion 51 of the support member 22. It is formed in a twisted shape along the longitudinal direction. In this case, the support member 22 can be inserted into or retracted from the insertion hole 21 in a state where the protrusion 51 and the hole 60 are fitted. Here, the assembly of the support member 22 to the light shielding plate 20 is performed by inserting the support member 22 into the insertion hole 21 without attaching the projection 51 to the perforation 50, and then inserting the projection 51 through the hole 60. This is done by fitting in the perforation 50 and fixing. The hole 60 formed in the insertion hole 21 may be a groove formed on the inner surface of the insertion hole 21 (that does not penetrate the wall).

Hereinafter, a mechanism for pulling out and winding up the curtain body 12 by moving the light shielding plate 20 in the vertical direction will be described with reference to FIG.
As shown in FIG. 2, a motor M is disposed below the rear window W, and a pinion gear 28 is attached to a drive shaft of the motor M. The pinion gear 28 meshes with a geared wire 30 that is driven in the vertical direction along the inside of the pair of guide rails 26a and 26b as the pinion gear 28 rotates. The slider 24 is attached to the tip of the geared wire 30.

  Therefore, when the pinion gear 28 rotates forward or backward by the driving force of the motor M, the slider 24 attached to the tip of the geared wire 30 is driven upward or downward along the inside of the pair of guide rails 26a and 26b. Thereby, it is possible to move the light shielding plate 20 attached to the slider 24 via the support member 22 in the vertical direction.

  As described above, the upper ends of the pair of guide rails 26a and 26b are inclined toward the inner side in the vehicle width direction. Therefore, when the light shielding plate 20 is moved in the vertical direction, the distance between the both ends of the light shielding plate 20 and the pair of guide rails 26a and 26b changes (specifically, with the drawing of the light shielding plate 20). However, since the support members 22 are attached to both ends of the light shielding plate 20, the support members 22 slide in the vehicle width direction with respect to the insertion holes 21 of the light shielding plate 20. By doing so, such a change in distance can be absorbed.

As described above, the support member 22 moves back and forth in the insertion hole 21 of the light shielding plate 20 so that the support member 22 and the light shielding plate 20 move relative to each other to absorb the distance between the guide rails 26a and 26b. Thus, as described above, with the relative movement between the support member 22 and the light shielding plate 20, the light shielding plate 20 rotates along the twist of the hole 60 formed in the insertion hole 21 thereof. Yes.
Specifically, as shown in FIG. 5, in the state where the light shielding plate 20 is pulled back (the curtain body 12 is stored), the light shielding plate 20 is in a sleeping state, and the light shielding function between the outside and the inside of the vehicle is not realized. On the other hand, in the state where the light shielding plate 20 is pulled out (the unfolded state of the curtain body 12), the light shielding plate 20 is in a standing state that is rotated along with the drawing, and has a light shielding function between the outside and the inside of the vehicle. Is realized (light-shielding state). Such rotation of the light shielding plate 20 is caused by twisting of the hole 60 formed along the longitudinal direction in the insertion hole 21 of the light shielding plate 20. The light shielding plate 20 rotates along the twist of the hole 60 by advancing and retreating to the insertion hole 21 of the light shielding plate 20 while maintaining the fitting with the protrusion 50.

  In the sunshade device 10 of the present embodiment as described above, the distance between the pair of guide rails 26a and 26b sandwiching the light shielding plate 20 decreases as the light shielding plate 20 is pulled out, but such guide rails 26a and 26b are disposed. The light shielding plate 20 and the support member 22 are attached so as to move relative to each other as the distance between them decreases, and the light shielding plate 20 is attached to each other so that the light shielding plate 20 can rotate along with the relative movement. Yes. Therefore, the light shielding plate 20 can be rotated regardless of the shape of the guide rails 26a and 26b (the shape along the drawing direction of the light shielding plate 20), and the linear guide rails 26a and 26b as in the present embodiment. Even if it exists, the light-shielding plate 20 can be rotated. Therefore, it is possible to save space compared to curved guide rails, and it is difficult to generate or deteriorate operating noise due to sliding or sliding resistance in curved guide rails, and there is no need for bending and other costs. Reduction is realized.

Second Embodiment
Next, a different embodiment (second embodiment) of the present invention will be described.
FIG. 6 is an enlarged perspective view of a main part showing the configuration of the support member 122 and the light shielding plate 120 included in the sunshade device of the second embodiment. In addition, in the sunshade apparatus of 2nd Embodiment, about the structure similar to the sunshade apparatus 10 of 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  Also in the second embodiment, the curtain body 12 can be expanded along the rear window W in accordance with the operation of pulling out the light shielding plate 120. And the supporting member 122 which consists of a elongate columnar member (bar-shaped member) is each attached to the right-and-left both ends of the light shielding plate 20. FIG. The support member 122 supports the light-shielding plate 120 and includes a columnar member (here, a columnar member) whose axial cross-sectional shape is substantially the same along the longitudinal direction, and has a surface along the longitudinal direction of the support member 122. A groove 150 formed in a twisted shape (spiral shape) is provided. Again, one end of each support member 122 is inserted into the insertion holes 121 formed at the left and right ends of the light shielding plate 120, and the other end is integrated with the slider 24 attached to the guide rails 26a and 26b. ing.

  On the other hand, the insertion hole 121 formed in the light shielding plate 120 has a hole shaft cross-sectional shape (here circular) corresponding to (similar to) the shaft cross-sectional shape of the support member 122, and thereby the support member 122 is swung. It is possible to insert without. Further, the insertion hole 121 is provided with a protrusion 160 that can be fitted into the groove 150 of the support member 122, that is, into the groove 150. With the protrusion 160 and the groove 150 fitted, the insertion hole 121 can be inserted into the insertion hole 121. The support member 122 can be inserted. Also in the second embodiment, the light shielding plate 120 and the support member 122 are relatively moved (approached or separated) from each other as the support member 122 advances and retreats with respect to the insertion hole 121. The light shielding plate 120 is rotated along the twist of the groove 150 of the support member 122.

  Also in the second embodiment, the upper ends of the pair of guide rails 26a and 26b are inclined toward the inner side in the vehicle width direction. Therefore, when the light shielding plate 120 is moved in the vertical direction, the distance between the both end portions of the light shielding plate 120 and the pair of guide rails 26a and 26b changes (specifically, as the light shielding plate 120 is pulled out). However, since the support members 122 are attached to both ends of the light shielding plate 120, the support members 122 slide in the vehicle width direction with respect to the insertion holes 121 of the light shielding plate 120. By doing so, such a change in distance can be absorbed.

  As described above, the support member 122 moves back and forth in the insertion hole 121 of the light shielding plate 120, so that the support member 122 and the light shielding plate 120 move relative to each other to absorb the distance between the guide rails 26a and 26b. Thus, as described above, with the relative movement between the support member 122 and the light shielding plate 120, the light shielding plate 120 rotates along the twist of the groove 150 of the support member 122. Specifically, in the state where the light shielding plate 120 is pulled back (the curtain body 12 is stored), the light shielding plate 120 is in a sleeping state and the state where the light shielding function between the outside and the inside of the vehicle is not realized (non-light shielding state). On the other hand, in the state in which the light shielding plate 120 is pulled out (the deployed state of the curtain body 12), the light shielding plate 120 is in an upright state that is rotated along with the drawer, and the light shielding function between the outside and the inside of the vehicle is realized (light shielding). State). Such rotation of the light shielding plate 120 is caused by twisting of the groove 150 formed along the longitudinal direction in the support member 122, and the support member 22 including the twisted groove 150 is connected to the groove 150 and the protrusion. By moving forward and backward in the insertion hole 121 of the light shielding plate 120 while maintaining the fitting with 160, the other light shielding plate 120 rotates along the twist.

  In the sunshade device of the second embodiment as described above, the light shielding plate 120 can be rotated regardless of the shape of the guide rails 26a and 26b (the shape along the drawing direction of the light shielding plate 120). Even with the guide rails 26a and 26b, the light shielding plate 120 can be rotated. Therefore, space saving can be realized as compared with the curved guide rails 26a and 26b, and the generation or deterioration of the operation sound due to the sliding or sliding resistance in the curved guide rail is less likely to occur, and bending work is not required. Therefore, cost reduction is realized.

<Third Embodiment>

Note that in the sunshade device of the third embodiment, the same components as those of the sunshade device 10 of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  Also in the third embodiment, the curtain body 12 can be unfolded along the rear window W in accordance with the drawing operation of the light shielding plate 220. A pair of support members 222 made of long columnar members (bar-shaped members) are attached to the left and right ends of the light shielding plate 220, respectively. The support member 222 is a member that supports the light-shielding plate 220 and has a configuration in which a columnar member having an axial cross-sectional shape (here, the shape of the alphabet “D”) is twisted along the longitudinal direction (that is, a spiral). Each end is inserted into an insertion hole 221 formed at both left and right ends of the light shielding plate 220, and the other end is attached to the guide rails 26a and 26b as shown in FIG. The slider 24 is integrated.

  On the other hand, the insertion hole 221 formed in the light shielding plate 220 has a hole shaft cross-sectional shape (here, the shape of the alphabet “D”) that is small in width from the opening portion and corresponds to (similar to) the shaft cross-sectional shape of the support member 222. The back side is formed in a cylindrical shape slightly larger than the diameter of the support member 222, and thus the support member 222 can be inserted without being shaken. The light shielding plate 220 and the support member 222 are relatively moved (approached or separated) from each other as the support member 222 advances and retreats with respect to the insertion hole 221, and the light shielding plate 220 is supported by the relative movement. It is assumed that it rotates along the twist of 222.

  Also in the third embodiment, the light shielding plate 220 and the support member 222 are relatively moved (approached or separated) from each other as the support member 222 advances and retreats with respect to the insertion hole 221. The plate 220 rotates along the twist of the support member 222.

  Also in the third embodiment, the upper ends of the pair of guide rails 26a and 26b are inclined toward the inner side in the vehicle width direction. Therefore, when the light shielding plate 220 is moved in the vertical direction, the distance between both ends of the light shielding plate 220 and the pair of guide rails 26a and 26b changes (specifically, as the light shielding plate 220 is pulled out). However, since the support members 222 are attached to both ends of the light shielding plate 220, the support members 222 slide in the vehicle width direction with respect to the insertion holes 221 of the light shielding plate 220. By doing so, such a change in distance can be absorbed.

  As described above, the support member 222 moves back and forth in the insertion hole 221 of the light shielding plate 220, so that the support member 222 and the light shielding plate 220 move relative to each other to absorb the distance between the guide rails 26a and 26b. As described above, the light shielding plate 220 rotates along the twist of the support member 222 in accordance with the relative movement between the support member 222 and the light shielding plate 220. Specifically, as shown in FIG. 8, in the state where the light shielding plate 220 is pulled back (lower right in the drawing: the curtain body 12 is stored), the light shielding plate 220 is in a sleeping state, and the light shielding between the outside and the inside of the vehicle is performed. The function is not realized (non-shielded state). On the other hand, in the state in which the light shielding plate 220 is pulled out (upper left in the drawing: the unfolded state of the curtain body 12), the light shielding plate 220 is in a standing state that is rotated along with the drawer, and the light shielding function between the outside and the inside of the vehicle is realized. (Shielded state). The rotation of the light shielding plate 220 is caused by a twist formed along the longitudinal direction of the support member 222. The twisted support member 222 advances and retracts into the insertion hole 221 of the light shielding plate 220, so The light shielding plate 20 rotates along the twist.

  In the sunshade device of the third embodiment as described above, the light shielding plate 220 can be rotated regardless of the shape of the guide rails 26a and 26b (the shape along the drawing direction of the light shielding plate 220), and the linear shape Even with the guide rails 26a and 26b, the light shielding plate 220 can be rotated. Therefore, space saving can be realized as compared with the curved guide rails 26a and 26b, and the generation or deterioration of the operation sound due to the sliding or sliding resistance in the curved guide rail is less likely to occur, and bending work is not required. Therefore, cost reduction is realized.
