  The invention described in Patent Document 1 has a complicated structure and a large number of parts. Therefore, the efficiency of the assembling work is not good, the cost is high, and the weight increases, which is not preferable.

  In the invention described in Patent Document 2 and the conventional sunshade device shown in the examples of FIGS. 20 to 23, the rail and the stopper are separate members (in addition, in Patent Document 2, a damper mechanism is provided), The number of parts is large and the assemblability is lowered, which is not preferable.

  The present invention was devised in view of the above points, and has a simpler structure with a smaller number of parts, is lighter in weight, and can improve the assembling property. It is an object of the present invention to provide a stopper structure.

  In order to solve the above problems, the sunshade stopper structure for a vehicle according to the present invention takes the following means. First, the first invention of the present invention is close to an openable and closable roof opening provided in a vehicle roof or a roof translucent part provided in a vehicle roof and formed with a transparent part that transmits light. A fully closed position that is disposed on the ceiling of the vehicle interior and blocks light directed from the roof opening or the roof translucent portion toward the vehicle interior, and a fully open position that maximizes the amount of light guided into the vehicle interior. It is a sunshade stopper structure of a vehicle that can slide between. The sunshade is composed of one or a plurality of shades that are plate-like members substantially parallel to the surface of the roof, and each of the shades is provided for each shade and is substantially disposed on the surface of the roof. It is sandwiched between a pair of rails provided in parallel and is slidable between the fully closed position and the fully open position along the rail, and each of the rails is an upper surface of an edge portion of the inserted shade And a rail inner lower surface facing the bottom surface of the edge of the inserted shade. Further, on the rail inner lower surface of the rail, a protrusion protruding toward the rail inner upper surface is provided on the front side of the vehicle or the rear side of the vehicle. The opening, which is a gap to the rail inner upper surface, is set larger than the thickness of the edge portion of the shade inserted between the rail inner lower surface and the rail inner upper surface.

  In the first aspect of the present invention, a protrusion that protrudes toward the rail inner upper surface is provided on the front side or the rear side of the vehicle on the rail inner lower surface, and a gap is provided between the upper end of the protrusion and the rail inner upper surface. It is an opening for insertion into the rail. By this protrusion, the shade inserted through the rail can be prevented from coming off the rail. Therefore, it is not necessary to close the opening with an elastic body so that the shade inserted through the opening does not come out of the opening. The simpler structure reduces the number of parts and improves the ease of assembly, resulting in lighter weight. Can be realized.

  Next, a second invention of the present invention is the sunshade stopper structure for a vehicle according to the first invention, wherein the protrusion is provided in the fully closed position when provided on the front side of the vehicle. When provided on the rear side of the vehicle, it is provided at a position corresponding to the fully opened position.

  In the second aspect of the invention, the fully closed stopper that stops at the fully closed position that is the end point when the shade inserted through the rail is moved toward the fully closed direction, or the shade inserted through the rail is directed toward the fully opened direction. The protrusion is used as a full-open stopper that stops at the full-open position that is the end point when the lens is moved. Thereby, it is not necessary to newly provide a stopper such as an elastic body, and it is possible to reduce the number of parts with a simpler structure, to further improve the assembling property, and to further reduce the weight.

  Next, a third invention of the present invention is a vehicle sunshade stopper structure according to the first invention or the second invention, wherein the protrusion is provided at a rear end of the rail. .

  In the third aspect of the invention, the opening is formed at the rear end of the rail by providing the protrusion at the rear end of the rail. For example, when the shade is damaged and needs to be replaced, rather than providing the opening in the front of the vehicle and inserting the shade from the front of the vehicle, the opening is provided in the rear of the vehicle and the shade is inserted from the rear of the vehicle. The insertion has more space and better workability. Further, by providing a protrusion at the rear end of the rail, waste of the length behind the rail can be eliminated.

  Next, 4th invention of this invention is the stopper structure of the sunshade of the vehicle which concerns on any one of the said 1st invention-3rd invention, Comprising: The said protrusion part is provided in the front-back direction of the said rail. The side opposite to the side that is covered is closed so as to prevent the shade inserted through the rail from coming off the rail.

  In the fourth aspect of the invention, when the projection (ie, the opening) is provided in front of the rail, the rear of the rail is closed, and when the projection (ie, the opening) is provided behind the rail, the front of the rail is closed. . Thereby, it can prevent more appropriately that the shade penetrated to the rail from the opening part comes off from the rail.

  Next, a fifth invention of the present invention is a sunshade stopper structure for a vehicle according to any one of the first to fourth inventions, wherein the vehicle has the roof translucent portion. The roof translucent part and the rail are integrally formed of resin.

  In the fifth invention, the roof translucent part and the rail are integrally formed of resin. Thereby, since the roof translucent part, the rail, and the projecting part are integrally formed of resin, the number of parts can be further reduced and the assembling property can be further improved. Further, by molding with resin, for example, it is possible to realize further weight reduction as compared with the case where the roof translucent portion is made of glass or the rail is made of metal.

  Next, a sixth invention of the present invention is a stopper structure for a vehicle sunshade according to any one of the first to fifth inventions, wherein the shade is inserted through the rail in the protrusion. The shape of the portion that may come into contact with the protrusion has a protrusion-side restriction shape that restricts the contacted shade from moving upward, and comes into contact with the protrusion in the shade inserted through the rail. The shape of the place where there is a case has the shade side regulation shape which regulates that the said shade moves upwards with respect to the protrusion part which contact | abutted.

  In the sixth aspect of the invention, it is possible to more appropriately prevent the shade inserted through the opening from coming out of the opening.

  Next, a seventh invention of the present invention is the vehicle sunshade stopper structure according to the sixth invention, wherein the protrusion-side regulating shape is higher than the lower side with respect to the abutting shade. The shade-side restriction shape is a shape that is inclined so that the upper part is separated from the projecting part rather than the lower part with respect to the projecting part.

  According to the seventh aspect of the present invention, the protrusion side restriction shape and the shade side restriction shape can be easily realized as more specific shapes.

  Next, an eighth invention of the present invention is a vehicle sunshade stopper structure according to any one of the first to seventh inventions, and is opposed to the rail inner upper surface of the projection. The surface is formed as a guide surface inclined so as to guide the shade to the opening when the shade is inserted through the opening.

[Vehicle Sunshade Stopper Structure in First Embodiment (FIGS. 2 to 16)]
Next, a first embodiment of a vehicle sunshade stopper structure will be described with reference to FIGS. In the first embodiment, as shown in the schematic diagram of FIG. 2, the sunshade includes a first shade 21 and a second shade that are plate-like members substantially parallel to the surface of the vehicle roof (in this case, the XY plane). 22 and 2 shades. The first shade 21 is sandwiched between a pair of first rails 31 substantially parallel to the surface of the vehicle roof, and is slidable between the fully closed position and the fully open position along the first rail 31. Similarly, the second shade 22 is sandwiched between a pair of second rails 32 substantially parallel to the surface of the vehicle roof, and is slidable between the fully closed position and the fully opened position along the second rail 32. . Thus, the 1st rail 31 and the 2nd rail 32 are provided for every corresponding shade, and are piled up in the up-and-down direction. The pair of first rails 31 on the left and right are arranged on the ceiling of the vehicle interior so as to sandwich the roof translucent part 11 from the left and right, and are arranged to extend in the front-rear direction. Similarly, the pair of second rails 32 on the left and right are also arranged on the ceiling of the vehicle interior so as to sandwich the roof translucent part 11 from the left and right, and are arranged to extend in the front-rear direction.

  In the example of FIG. 2, the first shade 21 disposed on the lower side (vehicle interior side) is a shade (corresponding to a moving shade) that is directly slid by the user, and the second shade disposed on the upper side. The shade 22 is a shade (corresponding to a driven shade) that slides in conjunction with the first shade 21 (moving shade). A fully-open locking member 21 </ b> F that protrudes toward the second shade 22 is attached to a position in the vicinity of the end portion of the first shade 21 on the side of the fully-closed direction and away from the first rail 31. In addition, a fully-closed locking member 21 </ b> R that protrudes toward the second shade 22 is attached to a position away from the first rail 31 in the vicinity of the end portion of the first shade 21 on the side of the fully open direction. A driven locking member 22 </ b> F that protrudes toward the first shade 21 is attached to a position in the vicinity of the end portion on the side of the fully closed direction in the second shade 22 that is away from the second rail 32. Note that the fully open locking member 21F, the fully closed locking member 21R, and the driven locking member 22F are soft materials such as rubber and are elastic bodies capable of absorbing impact.

  The fully open locking member 21F, the fully closed locking member 21R, and the driven locking member 22F constitute an interlocking mechanism. When the first shade 21 (moving shade) is slid in the fully closed direction, the fully closed locking member 21R comes into contact with the driven locking member 22F in the fully closed direction (see FIG. 3), and the second shade. 22 (driven shade) is slid in the fully closed direction in conjunction with the first shade 21. Further, when the first shade 21 (moving shade) is slid in the fully open direction, the fully open locking member 21F comes into contact with the driven locking member 22F in the fully open direction (see FIG. 6), and the second shade 22 (driven) The shade) is slid in the fully open direction in conjunction with the first shade 21.

  The first rail 31 and the second rail 32 are made of resin. As shown in FIG. 7 which is an example of the VII-VII cross section of FIG. 2, the first rail 31 and the second rail 32 are roofs. The roof 2 including the translucent part 11 is integrally formed. In FIG. 7, the roof translucent part 11 which is a transparent member and the non-transparent part 12 including the rails 30 (the first rail 31 and the second rail 32) are integrally formed by resin two-color molding.

  As shown in FIGS. 3 and 6, the first rail 31 has a fully closed stopper 31 </ b> F integrally formed with the first rail 31 at the end portion in the fully closed direction. The second rail 32 is integrally formed with the second rail 32 at a full opening stopper 32F at an end portion on the side in the full opening direction. Thus, when the first shade 21 is slid in the fully closed direction, the first shade 21 comes into contact with the fully closed stopper 31F and the sliding in the fully closed direction is restricted (see FIG. 3). Further, when the first shade 21 is slid in the fully open direction, the second shade 22 comes into contact with the fully open stopper 32F and the sliding in the fully open direction is restricted (see FIG. 6).

  The fully closed stopper 31F provided at the end of the first rail 31 in the fully closed direction is opposite to the opening 31K (see FIGS. 3 and 5) formed at the end of the first rail 31 in the fully open direction. The side (the side opposite to the protrusion 31T) is closed. The fully closed stopper 31 </ b> F is not limited to a bag path shape that seals the opening at the end, and may be, for example, a small protrusion. In addition, you may make it provide the projection part mentioned later instead of the fully-closed stopper 31F of the 1st rail 31 of the fully-closed direction. The fully closed stopper 31F and the protrusion 31T (see FIG. 3) are integrally formed with the first rail 31.

  The fully open stopper 32F provided at the end of the second rail 32 in the fully open direction is opposite to the opening 32K (see FIGS. 3 and 4) formed at the end of the second rail 32 in the fully closed direction. (The side opposite to the protrusion 32T) is closed. In addition, the fully open stopper 32F is not limited to the shape of a bag path that seals the opening at the end, and may be, for example, a small protrusion. In addition, you may make it provide the projection part mentioned later instead of the full open stopper 32F of the full open direction of the 2nd rail 32. FIG. The fully open stopper 32F and the protrusion 32T (see FIG. 3) are integrally formed with the second rail 32.

  As shown in FIGS. 3 to 6, a protruding portion 31 </ b> T protruding from the rail inner lower surface 31 </ b> L toward the rail inner upper surface 31 </ b> U is integrated with the first rail 31 at the rear end portion of the first rail 31 which is the fully open position. An opening 31K is formed between the upper end of the protrusion 31T and the rail inner upper surface 31U. In addition, a protrusion 32T that protrudes from the rail inner lower surface 32L toward the rail inner upper surface 32U is formed integrally with the second rail 32 at the front end of the second rail 32 that is in the fully closed position, and the upper end of the protrusion 32T is formed. An opening 32K is formed between the rail and the rail inner upper surface 32U.

● [Structure of protrusion (31T) and opening (31K) (FIGS. 8 to 11)]
Next, the structure and the like of the protrusion 31T and the opening 31K provided on the first rail 31 will be described with reference to FIGS. 8 is a perspective view showing a state immediately before the first shade 21 is inserted into the first rail 31 from the opening 31K formed in the first rail 31, and FIG. 9 is a view of FIG. 8 seen from the IX direction. FIG. 10 is a perspective view showing a state in which the first shade 21 is inserted into the first rail 31 from the opening 31K formed in the first rail 31, and FIG. 11 is a view of FIG. 10 viewed from the XI direction. is there. As shown in FIG. 4, the rail inner upper surface 31 </ b> U is a surface of the first rail 31 that faces the upper surface of the edge portion of the first shade 21 inserted through the first rail 31. Further, the rail inner lower surface 31 </ b> L is a surface of the first rail 31 that faces the lower surface of the edge portion of the first shade 21 inserted through the first rail 31. As shown in FIG. 4, the rail inner upper surface 32 </ b> U is a surface of the second rail 32 that faces the upper surface of the edge portion of the second shade 22 inserted through the second rail 32. The rail inner lower surface 32 </ b> L is a surface of the second rail 32 that faces the lower surface of the edge portion of the second shade 22 inserted through the second rail 32. Further, the thickness 21H of the edge of the first shade 21 and the thickness 22H of the edge of the second shade 22 are provided with a spring or the like at the edge of the shade to fill a gap between the edge of the shade and the rail. When a filling member (a member generally called a “shoe”) is attached, this corresponds to the thickness of the filling member (the thickness in a state where a spring or the like is compressed).

  As shown in FIG. 9, the opening height 31H, which is the distance from the upper end of the protrusion 31T to the rail inner upper surface 31U in the opening 31K, is the thickness of the edge of the first shade 21 inserted through the first rail 31. Is greater than 21H (opening height 31H> edge thickness 21H of first shade 21). The edge of the first shade 21 is a portion of the first shade 21 that is sandwiched between the rail inner upper surface 31U and the rail inner lower surface 31L when the first shade 21 is inserted through the first rail 31. As shown in FIG. 11, the lower surface of the edge portion of the first shade 21 inserted through the first rail 31 is in contact with the rail inner lower surface 31L by gravity, and the first shade 21 is moved in the fully open direction. At this time, the protrusion 31T stops at the fully open position. The protrusion height 31TH, which is the distance from the upper end of the protrusion 31T to the rail inner lower surface 31L, is set to, for example, about 1 [mm] to several [mm]. The protrusion height 31TH is set to an appropriate height so that the first shade 21 can be appropriately prevented from coming out of the opening 31K, and the height of the first rail 31 is not increased more than necessary. As shown in FIGS. 8 and 10, the operator can easily insert the first shade 21 from the opening 31 </ b> K into the first rail 31. Further, as described above, the first shade 21 inserted through the first rail 31 is not easily removed from the opening 31K by the protrusion 31T.

  As shown in FIG. 4, a protrusion 32T that protrudes toward the rail inner upper surface 32U is formed at the front end portion (end portion in the fully closed direction) of the rail inner lower surface 32L of the second rail 32. An opening 32K that is a gap from the upper end of the portion 32T to the rail inner upper surface 32U is formed. The opening height 32H, which is the distance from the upper end of the protrusion 32T to the rail inner upper surface 32U in the opening 32K, is larger than the thickness 22H of the edge of the second shade 22 inserted through the second rail 32 (opening). The height 32H> the thickness 22H of the edge of the second shade 22). Further, the lower surface of the edge portion of the second shade 22 inserted through the second rail 32 is in contact with the rail inner lower surface 32L due to gravity, and when the second shade 22 is moved in the fully closed direction, the protrusion 32T It stops at the fully closed position. The protrusion height, which is the distance from the upper end of the protrusion 32T to the rail inner lower surface 32L, is set to, for example, about 1 [mm] to several [mm]. The operator can easily insert the second shade 22 into the second rail 32 from the opening 32K. Further, as described above, the second shade 22 inserted through the second rail 32 is not easily removed from the opening 32K by the protrusion 32T.

  In the above description, the example in which the fully closed stopper 31F and the protrusion 31T are integrally formed on the first rail 31 and the fully open stopper 32F and the protrusion 32T is integrally formed on the second rail 32 has been described. A fully-closed stopper is integrally formed at the end of the fully-closed direction, and a protrusion is provided at the end of the fully-opened direction. A fully open stopper may be integrally formed at the end of the first and a protrusion may be provided at the end in the fully closed direction. In addition, at the time of full opening shown in FIG. 6, the rail (the second shade 22 in the example of FIG. 6) that supports the shade (the second shade 22 in the example of FIG. 6) whose end portion in the full opening direction (the rear end portion in the example of FIG. In the example of FIG. 6, it is more preferable to form the fully open stopper integrally with the second rail 32) because the fully open stopper can be provided at a position where the force in the fully open direction is most applied. Similarly, when fully closed as shown in FIG. 3, the end (the front end in the example of FIG. 3) in the fully closed direction supports the shade (the first shade 21 in the example of FIG. 3) that protrudes in the fully closed direction. It is more preferable to form the fully closed stopper integrally with the rail (first rail 31 in the example of FIG. 3) because the fully closed stopper can be provided at a position where the force in the fully closed direction is most applied.

  As described above, the roof 2, including the roof translucent portion 11, the first rail 31, the fully closed stopper 31F, the second rail 32, the fully opened stopper 32F, and the protruding portions 31T and 32T are integrally formed of resin. Thus, the stoppers 122S and 122T can be omitted from the conventional sunshade stopper structure shown in FIG. Therefore, the assembling property can be further improved with a smaller number of parts. Moreover, weight reduction can also be implement | achieved by setting it as the integrally molded product of resin.

● [Example of a structure that more appropriately prevents the shade inserted through the rail from coming out of the opening (FIGS. 12 and 13)]
The shape of the protrusion 31T described in the examples of FIGS. 2 to 11 was a substantially rectangular parallelepiped shape. However, in the shape shown in the example of FIGS. 12 and 13, the shape of the portion that may contact (oppose) the first shade 21 inserted through the first rail 31 in the protrusion 31 </ b> T may be 1 shade 21 has a protrusion side regulation shape which regulates that it moves upwards. Moreover, the shape of the part which may contact with the protrusion part 31T in the 1st shade 21 penetrated by the 1st rail 31 (facing) is the 1st shade 21 upwards with respect to the protrusion part 31T which contacted. It has a shade-side restriction shape that restricts movement. By adopting this shape, when the shade inserted through the rail comes into contact with the protrusion, the shade is prevented from moving upward with respect to the protrusion, and the shade is more appropriately prevented from coming out of the opening. can do. Hereinafter, the first rail 31, the protrusion 31T, and the first shade 21 will be described as an example. However, the second rail 32, the protrusion 32T, and the second shade 22 are the same, and thus the description thereof is omitted.

  In the example of FIG. 12, the protruding portion side restriction shape of the protruding portion 31 </ b> T is such that the protruding portion side facing surface 31 </ b> TT is closer to the first shade 21 on the upper side than on the lower side. It has a tapered shape that is slanted. Further, the shade-side restriction shape in the first shade 21 is a tapered shape in which the shade-side facing surface 21T is inclined with respect to the opposing protruding portion 31T so that the upper side is separated from the protruding portion 31T in the upper side rather than the lower side. Have. With this shape, it is possible to appropriately prevent the first shade 21 from moving upward with respect to the protrusion 31T. In addition, in FIG. 12, the inclination angle θ1 of the protrusion-side restriction shape and the shade-side restriction shape with respect to the vertical direction is not particularly limited, but is set to an appropriate angle. This shape is very simple and easy to process.

  In the example of FIG. 13, the protruding portion side restricting shape of the protruding portion 31 </ b> T is a shape in which the upper end portion of the protruding portion 31 </ b> T has an upper end protruding portion 31 </ b> TK protruding toward the opposing first shade 21. . The shade-side restriction shape of the first shade 21 is a shape in which the lower end portion of the first shade 21 has a lower end protruding portion 21K that protrudes toward the protruding portion 31T facing the first shade 21. With this shape, it is possible to appropriately prevent the first shade 21 from moving upward with respect to the protrusion 31T.

● [Other examples of protrusion structure (FIGS. 14 to 16)]
The example of the protrusion 31T shown in FIG. 14 is a guide surface that is inclined so that the surface of the protrusion 31T that faces the rail inner upper surface 31U gradually moves away from the rail inner upper surface 31U as it approaches the end of the first rail 31. This is an example of 31TM. The inclination angle θ2 of the guide surface 31TM with respect to the insertion direction of the first shade 21 is not particularly limited, but is set to an appropriate angle. When the first shade 21 is inserted into the first rail 31 from the opening 31K by the guide surface 31TM, the first shade 21 is appropriately guided to the opening 31K.

  In the example of the protrusions 31T and 31W shown in FIGS. 15 and 16, a protrusion 31W protruding toward the rail inner lower surface 31L is formed on the rail inner upper surface 31U facing the protrusion 31T formed on the rail inner lower surface 31L. An example is shown. The protrusion height 31WH, which is the distance from the rail inner upper surface 31U to the tip of the protrusion 31W, is equivalent to the protrusion height 31TH, which is the distance from the rail inner lower surface 31L to the protrusion 31T. In this structure, as shown in the example of FIG. 15, the first shade 21 inserted through the first rail 31 is usually in contact with the rail inner lower surface 31L due to gravity, so that the protrusion 31T allows the first shade 21 to pass through the opening 31K. It is prevented from coming off. Further, as shown in the example of FIG. 16, even if the first shade 21 comes into contact with the rail inner upper surface 31U against gravity, the protrusion 31W prevents the protrusion 31W from coming out of the opening 31K.
