The vehicle shade device 100 is configured to be symmetrical overall.

[0010] As shown in Figs. 1A and 1B, the vehicle shade device 100 has a shade 1 made of a cloth or other material (e.g., vinyl) having a light-shielding property, which is arranged along the inner surface of the windshield 3. A roof console 2 is attached to the front end of a roof 200 inside the vehicle cabin, and the shade 1 and the roof console 2 constitute the vehicle shade device 100. The shade 1 is wrapped around the roof console 2. Fixed fixed The axis The fixed shaft is provided so as to be rotatable but immovable, one end (base end) of the shade 1 is fixed to the fixed shaft, and the other end (tip end) of the shade 1 is extended as the fixed shaft rotates. In other words, the shade 1 is configured as a roll shade.

[0011] A hook 11 (see FIG. 6) is provided at the left-right center of the tip of the shade 1. A holder 41 is provided on the top surface of the dashboard (also called the instrument panel) 4 at the front of the vehicle interior. The hook 11 engages with the holder 41, thereby allowing the shade 1 to be fixed in an in-use position. When the hook 11 is detached from the holder 41, the shade 1 can be wound around a fixed shaft in the roof console 2, allowing the shade 1 to be moved to a non-use position retracted from the inner surface of the windshield 3.

[0012] The roof console 2 is an optional vehicle accessory that can be attached to the roof 200 inside the vehicle cabin. Fig. 2 is a perspective view of the roof console 2 seen from diagonally lower left, and Fig. 3 is a perspective view seen from diagonally upper left. Figs. 2 and 3 each show a state in which the shade 1 is wound up around a fixed shaft, and the shade 1 is in a non-use position.

[0013] 2 and 3, the roof console 2 has a resin container member 20 that extends in the left-right direction across the entire width of the vehicle and also extends a predetermined length in the front-rear direction. An upper surface of the container member 20 is provided with a concave storage portion 201 that extends elongatedly in the left-right direction, and a pair of left and right concave storage portions 202. Storage portion 202 is disposed behind storage portion 201, and a reinforcing member 21 is provided between storage portions 201 and 202, extending from the right end to the left end of the container member 20. Note that reinforcing member 21 may be omitted.

[0014] The rear storage section 202 forms a substantially box-shaped space with an open rear surface between the roof 200 (FIG. 1B). Small items can be stored in the storage section 202 through the opening at the rear surface, and the roof console 2 functions as a storage case. A slender slit hole 202a is opened in the left-right direction in the bottom surface of the storage section 202, and when a tissue box is stored in the storage section 202, tissue paper can be taken out through the slit hole 202a. The front storage section 201 is provided with a shade unit 10 extending in the left-right direction. The shade unit 10 has an upper cover 6 at the top that extends over the entire left-right length of the storage section 201. The upper cover 6 is pressed from above by a fixing member 65 and fixed to the roof console 2. As shown in FIG. 2, a slit hole 23 is opened in the left-right direction in the front end portion of the container member 20, and the shade 1 can be pulled out below the container member 20 through the slit hole 23.

[0015] FIG. 4 is a cross-sectional view of the main part of the vehicle shade device 100 taken along line IV-IV in the center of the left-right direction in FIG. 3. As shown in FIG. 4, the upper cover 6 has a substantially arc-shaped cross section and a substantially semicircular recess 6a on the inside. The shade unit 10 includes, in addition to the shade 1 and the upper cover 6, a fixed shaft 12 that is elongated in the left-right direction and is disposed in the recess 6a on the inside of the upper cover 6, and an operating member 16 that is operated by a user. FIG. 5 is a perspective view showing the overall configuration of the shade unit 10, and corresponds to the unused position of the shade 1. As shown in FIG. 5, side covers 7 are attached to both left and right ends of the upper cover 6. The upper cover 6 and the side covers 7, together with the roof console 2, constitute a storage section for storing the shade 1.

[0016] As shown in FIG. 4, the fixed shaft 12 has a generally cylindrical cylinder 13 extending in the left-right direction centered on a left-right axis CL1. The cylinder 13 is rotatably supported by the side cover 7 (FIG. 5) via a shaft (not shown) extending along the axis CL1. The base end of the shade 1 is fixed to the outer circumferential surface of the cylinder 13, and the shade 1 is wound around the cylinder 13. The tip of the shade 1 is fixed to a generally cylindrical rod 17 extending in the left-right direction along a left-right axis CL2. The diameter of the rod 17 is smaller than the width of the slit hole 23, and the rod 17 can pass through the slit hole 23.

[0017] As shown in Figs. 4 and 5, the operating member 16 is provided at the center of the shade 1 in the left-right direction. Fig. 6 is a perspective view showing the configuration of the operating member 16 alone. As shown in Figs. 4 and 6, the operating member 16 has a substantially cylindrical holding portion 161 extending in the left-right direction and supporting the rod body 17, a substantially plate-shaped gripping portion 162 extending rearward from the lower end of the holding portion 161, and a protrusion 163 extending forward from the lower end of the holding portion 161 and downward (diagonally downward) from the gripping portion 162. A substantially rod-shaped engagement protrusion 164 is provided at the front end of the protrusion 163 in the left-right direction. The protrusion 163 and the engagement protrusion 164 form a hook 11 (Fig. 1A), and the operating member 16 has the hook 11 integrally therewith.

[0018] As shown in FIG. 4, a recess 24 recessed upward is provided in front of the slit hole 23 on the bottom surface of the container member 20. When the user pushes the protrusion 163 of the operation member 16 upward (in the direction of the arrow A in FIG. 4), the protrusion 163 moves into the recess 24, and the operation member 16 rotates with the holding part 161 as a fulcrum. This causes the grip part 162 to move downward (in the direction of the arrow B in FIG. 4), and the user can easily grip the grip part 162. Although detailed illustration is omitted, as shown in FIG. 5, a spring (e.g., a coil spring) 18 is provided inside the cylinder 13 along the axis CL1 (FIG. 4). One end of the spring 18 is fixed to a non-rotating member (e.g., a shaft in the cylinder 13), and the other end is fixed to a rotating member (e.g., the cylinder 13). As a result, a biasing force F0 that rolls up the shade 1 in the direction of the arrow in FIG. 5 always acts on the cylinder 13.

[0019] FIG. 7 is a perspective view showing an example of the operation of lowering the shade 1 to the use position. As shown in FIG. 7, the holder 41 is attached to the upper surface of the dashboard 4. For example, the holder 41 is attached by adhering with double-sided tape. The holder 41 is configured to have a substantially U-shaped cross section from the bottom surface to the rear surface and the top surface, and a notch 41a is provided on the top surface of the holder 41 from the front edge to the rear. A protrusion 163 of the operating member 16 is inserted from the front into the notch 41a, and an engagement protrusion 164 is disposed below the top surface of the holder 41. As a result, the hook 11 is engaged with the holder 41, and the shade 1 can be held in the use position against the biasing force of the spring 18.

[0020] Although detailed illustration is omitted, as shown in Fig. 5, a stopper 19 that stops the winding of the shade 1 by the spring 18 is provided at the axial end of the cylinder 13. The stopper 19 can be configured, for example, with a ratchet mechanism. This allows the shade 1 to be held in an extended state at any desired position.

[0021] In the above configuration, vibrations act on the vehicle shade device 100 while the vehicle is traveling, and this may cause the mounting portion of the spring 18 to loosen, and the biasing force of the spring 18 for biasing the shade 1 to the non-use position may decrease. In addition, the biasing force of the spring 18 may also decrease due to deterioration over time. If the biasing force of the spring 18 decreases, it may become difficult to hold the shade 1 in the non-use position when vibrations or impacts occur while the vehicle is traveling. Therefore, in this embodiment, the vehicle shade device 100 is further configured as follows so that the shade 1 can be stably held in the non-use position even if the biasing force of the spring 18 decreases.

[0022] FIG. 8 is a perspective view (obliquely seen from the front) showing the main configuration of the vehicle shade device 100 according to this embodiment, that is, a view taken along the arrow VIII in FIG. 5. As shown in FIG. 8, both left and right ends of the rod body 17 are protruded outward in the left and right direction from the left and right end faces of the shade 1, and a substantially ring-shaped roller 141 and a substantially cylindrical cap 14 are attached to the protruding portions. The cap 14 is made of, for example, a hard resin material, and is disposed outward in the left and right direction from the roller 141. The cap 14 extends on the same axis CL2 as the rod body 17. The outer circumferential surface of the cap 14 has a smaller diameter than the roller 141 and a larger diameter than the rod body 17. The rod body 17 and the cap 14 extend along the axis CL2 and form a movable shaft 101 that can move.

Furthermore, a cover support portion 72 having a substantially semicircular shape centered on the axis line CL1 is provided on the inner surface of the upper side cover 7A in the left-right direction so as to protrude inward in the left-right direction and cover the periphery (upper side, front side, rear side) of the support portion 71. A screw hole 72a is provided on the front end and rear end of the cover support portion 72 facing rearward and forward, respectively.

[0025] As shown in Fig. 4 and Fig. 8, the upper cover 6 has an arc portion 61 of a substantially semi-cylindrical shape formed in a convex shape facing upward, and a flat plate portion 62 extending substantially horizontally forward from the front end portion of the arc portion 61. As shown in Fig. 8, the left and right ends of the upper cover 6 are attached to the outer circumferential surface of the cover support portion 72. A bolt 72b passing through the upper cover 6 is screwed into the screw hole 72a of the cover support portion 72, thereby fixing the upper cover 6 to the side cover 7. At this time, the flat plate portion 62 of the upper cover 6 is disposed so as to cover the upper end portion (upper plate portion 76) of the lower side cover 7B.

[0026] As shown in Fig. 9A, a substantially rectangular flap support part 73 is provided on the inner surface of the lower side cover 7B in the left-right direction, protruding inward in the left-right direction. The left-right protrusion amount of the flap support part 73 is equal to the left-right protrusion amount of the cover support part 72, and the left-right inner end face of the flap support part 73 and the left-right inner end face of the cover support part 72 are located on the same vertical plane. The flap support part 73 has a front plate part 74 and a rear plate part 75 extending in the up-down direction, and an upper plate part 76 and a lower plate part 77 extending in the front-rear direction. The upper ends of the front plate part 74 and the rear plate part 75 and both front-rear ends of the upper plate part 76 are connected via inclined parts 78, and the upper corners of the flap support part 73 are inclined.

[0027] Further, on the inner surface in the left-right direction of the lower side cover 7B, an inner plate portion 79 is provided to protrude inward in the left-right direction, rearward of the front plate portion 74 and forward of the rear plate portion 75, at a predetermined distance from the front plate portion 74 and the rear plate portion 75, respectively. The inner plate portion 79 extends in the vertical direction approximately parallel to the front plate portion 74 and the rear plate portion 75, with a predetermined gap from the lower plate portion 77 and the inclined portion 78. The lower plate portion 77 is provided at its center in the front-rear direction. gap 77a is provided. gap The front edge of 77a is located rearward of the front inner plate portion 79, gap The rear edge of 77a is located forward of the rear inner plate portion 79. gap A length L1 of 77a in the front-rear direction is longer than a diameter D1 of the outer circumferential surface of cap 14. As shown in Figures 8 and 9A, front plate portion 74 and rear plate portion 75 are provided with a pair of upper and lower cutouts 74a, 75a extending from their inner end surfaces in the left-right direction outward in the left-right direction.

[0028] The flap 8 is disposed inside the flap support portion 73. The flap 8 has a substantially rectangular frame shape that conforms to the inner shape of the flap support portion 73. That is, as shown in FIG. 9A, the flap 8 has a pair of front and rear plates 81 and 82, and a pair of upper and lower plates 83 and 84. The front plate 81 is disposed between the front plate 74 of the flap support portion 73 and the front inner plate 79. The rear plate 82 is disposed between the rear plate 75 of the flap support portion 73 and the rear inner plate 79. The flap 8 is thus positioned by the flap support portion 73. The entire flap 8 is made of, for example, a flexible rubber material.

[0029] The lower plate portion 84 of the flap 8 is provided with a gap 84a is provided. gap The length L2 of 84a in the front-rear direction is gap77a and is shorter than the length L1 in the front-rear direction of the cap 14, and shorter than the diameter D1 of the cap 14. A pair of upper and lower engagement shafts 81a, 82a are provided on the front plate portion 81 and the rear plate portion 82 of the flap 8 to protrude forward and rearward, respectively. The engagement shafts 81a, 82a are press-fitted into the notches 74a, 75a of the flap support portion 73. As shown in Figs. 8 and 9A, flange portions 81b, 82b having a larger diameter than the notches 74a, 75a are provided at the tip portions of the engagement shafts 81a, 82a, and when the engagement shafts 81a, 82a are press-fitted into the notches 74a, 75a, the flange portions 81b, 82b are positioned outside the flap support portion 73 in the front-rear direction.

[0030] 9A shows the shade 1 in its fully wound state, which corresponds to the unused position of the shade 1. At this time, the cap 14 is located inside the flap 8. FIG. 9B shows the state in which the shade 1 has been unrolled a predetermined amount from the state shown in FIG. 9A. Since the shade 1 and the cap 14 are provided integrally, when the shade 1 is unrolled, the cap 14 gap It moves downward below the side cover 7 via 84a.

[0031] 10A is a diagram showing a typical deformation of the flap 8 in this case. As shown in FIG. 10A, when the cap 14 constituting the movable shaft 101 moves downward, the tip of the lower plate portion 84 of the flap 8 The edge The cap 14 presses the lower plate 84 downward, and the tip of the lower plate 84 elastically deforms downward. gap The cap 14 bends the lower plate portion 84 downward. gap The force required for the cap 14 to pass through the lower plate portion 84a is called the required downward force F1. The required downward force F1 does not include the force against the biasing force F0 of the spring 18. gap After passing through 84a, as shown in FIG. 9B, the lower plate portion 84 returns to its original shape due to elastic deformation.

[0032] On the other hand, when the shade 1 is moved from the use position to the non-use position, the cap 14 is moved to the lower plate portion 84 of the flap 8. gap84a and moves to the inside of flap 8. FIG. 10B is a diagram showing a typical deformation of flap 8 in this case. As shown in FIG. 10B, when cap 14 moves upward, the tip of lower plate portion 84 of flap 8 is pushed upward by cap 14, and the tip of lower plate portion 84 is elastically deformed upward. At this time, lower plate portion 84 is bent with the inner corner in the front-rear direction of the lower end portion of inner plate portion 79 as fulcrum P2. When cap 14 bends lower plate portion 84 upward, gap The force required for the cap 14 to pass through the lower plate portion 84a is called the necessary pushing force F2. gap After passing through 84a, as shown in FIG. 9A, the lower plate portion 84 returns to its original shape due to elastic deformation.

[0033] 10A and 10B, the position of the fulcrum P1 when the lower plate portion 84 is bent downward is located inward in the front-rear direction ( gap 84a side). Therefore, the downward force F1 required to bend the shade 1 downward is larger than the upward force F2 required to bend the shade 1 upward, and is larger than the gravity of the movable shaft 101. This makes it possible to prevent the shade 1 from falling from the non-use position even if the vehicle is subjected to vibrations with the biasing force F0 of the spring 18 (FIG. 5) reduced.

[0034] In this embodiment, the biasing force F0 of the spring 18 is set to a value greater than the required push-up force F2. This allows the biasing force F0 of the spring 18 to elastically deform the lower plate portion 84 of the flap 8, so that the shade 1 can be automatically moved to the non-use position.

[0035] The operation of the vehicle shade device 100 according to this embodiment can be summarized as follows. When moving the shade 1 from the non-use position to the use position, the user first operates the operation member 16 exposed below the roof console 2 from the state shown in Fig. 2 to pull the movable shaft 101 downward and pull out the shade 1. More specifically, as shown in Fig. 4, the user pushes the protrusion 163 of the operation member 16 upward (in the direction of arrow A) to rotate the grip portion 162 downward (in the direction of arrow B) and grips the grip portion 162. Next, the user lowers the movable shaft 101 against the biasing force F0 of the spring 18 (Fig. 5).

[0036] When the movable shaft 101 is lowered by a predetermined amount, the caps 14 at both ends of the movable shaft 101 come into contact with the lower plate portion 84 of the flap 8 by the necessary downward force F1, as shown in FIG. 10A, and the lower plate portion 84 is pushed downward. Gap side end The lower plate portion 84 is bent downward by elastic deformation with the fulcrum P1 at this point. gap 84a is pushed open and cap 14 is gap 84a. When the shade 1 is pulled out to the use position, as shown in Fig. 7, the hook 11 of the operating member 16 engages with the notch 41a of the holder 41 attached to the upper surface of the dashboard 4. This holds the shade 1 in the use position, and the inner surface of the windshield 3 is covered with the shade 1 as shown in Fig. 1A.

[0037] When moving the shade 1 from the use position to the non-use position, the user grips the gripping portion 162 of the operating member 16 to release the hook 11 from the notch 41a of the holder 41. As a result, the shade 1 is wound up by the biasing force F0 of the spring 18, and the movable shaft 101 moves upward. The biasing force F0 of the spring 18 is greater than the necessary pushing-up force F2 of the flap 8. Therefore, when the cap 14 comes into contact with the lower plate portion 84 of the flap 8 due to the upward movement of the movable shaft 101, the lower plate portion 84 is pushed upward as shown in FIG. 10B. More specifically, the lower plate portion 84 is bent upward by elastic deformation, with the lower end portion of the inner plate portion 79 of the flap support portion 73 serving as the fulcrum P2. As a result, gap 84a is pushed open and cap 14 is gap 84a, the shade 1 moves to the unused position. When the shade 1 moves to the unused position, only the operating member 26 is exposed from the roof console 2, as shown in Fig. 2. Therefore, the shade 1 is not visible to the passengers, improving the appearance of the vehicle interior.

[0038] According to this embodiment, the following advantageous effects can be obtained. (1) The vehicle shade device 100 includes a shade 1 that can be pulled downward from a non-use position to a use position that covers the inner surface of the windshield 3 of the vehicle, a storage section (roof console 2, upper cover 6, side cover 7) in which the shade 1 in the non-use position is stored, and a movable shaft 101 that is attached to the end of the shade 1 on the pull-out side and extends substantially horizontally along an axis CL2 (FIGS. 1A and 8). The storage section is a space through which the movable shaft 101 (cap 14) passes when the shade 1 is pulled out from the non-use position to the use position. gap The flap 8 is pushed by the cap 14 when the shade 1 is pulled out. gap The area of ​​84a is provided to be elastically deformable so as to expand (FIG. 9A).

[0039] As a result, even if the spring 18 deteriorates over time or is damaged, the shade 1 can be stably held in the non-use position regardless of the vibrations that occur when the vehicle is traveling. This reliably prevents the windshield 3 from being covered by the shade 1 while the vehicle is traveling, ensuring good visibility for the driver while driving. Since the shade 1 is stored when not in use, it is not visible to passengers and the appearance of the interior of the vehicle is also good.

[0040] (2) Flap 8, gap The side cover 7 has a pair of front and rear lower plate portions 84 arranged opposite each other with an upper plate portion 84a therebetween (FIG. 9A). The side cover 7 has a flap support portion 73 (lower plate portion 77) that supports the base ends of the pair of front and rear lower plate portions 84 (FIG. 9A). gapThe lower plate 84a is provided between the front and rear end portions of the pair of lower plate portions 84, and the front and rear end portions of the pair of lower plate portions 84 are provided so as to be bendable at their respective ends. This makes it possible to prevent the shade 1 from falling from the unused position with a simple configuration.

[0041] (3) The pair of front and rear lower plate portions 84 are respectively provided to protrude from the tip end portions of the pair of front and rear lower plate portions 77 of the flap support portion 73, and are provided so as to be bendable with the tip end portion as a fulcrum P1 (FIG. 10A). This allows the position of the bending fulcrum of the flap 8 to be easily changed, and the movable shaft 101 gap It is easy to set the necessary downward force F1 required to pass through 84a.

[0042] (4) The pair of front and rear lower plate portions 84 are provided so as to be bendable upward and downward, and the position of the fulcrum P1 when bent downward is larger than the position of the fulcrum P2 when bent upward. gap 84a (FIGS. 10A and 10B). This allows the force required to unfold the shade 1 to be set greater than the force required to roll it up.

[0043] (5) The flap 8 is provided at positions corresponding to both axial ends of the movable shaft 101 so that the flap 8 is pushed by both axial ends of the movable shaft 101 when the shade 1 is pulled out. More specifically, the flap 8 is fixed to the flap support portion 73 by press-fitting the engagement shafts 81a, 82a into the notches 74a, 75a of the flap support portion 73 (FIGS. 8 and 9A). When the flap 8 is provided on a part other than the side cover 7, it is necessary to separately provide a stay or the like for supporting the flap 8. However, in this embodiment, the flap 8 is supported by the side cover 7, and therefore such a stay is not necessary.

[0044] (6) The movable shaft 101 has caps 14 at both axial ends thereof that form the outer circumferential surface of the movable shaft 101 (FIG. 8). This makes it possible to easily adjust the necessary downward pressure F1 of the shade 1 simply by changing the diameter of the caps 14.

As a result, the movable shaft 101 pushes the lower plate portion 84 of the flap 8 apart due to the biasing force F0 of the spring 18, and the movable shaft 101 automatically gap 84a, thereby instantly moving the shade 1 from the use position to the non-use position.

[0049] This embodiment can be modified in various ways. Some modifications will be described below. In the above embodiment, the flap 8 gap 84 aAlthough a pair of front and rear lower plate portions 84 (first elastic body, second elastic body) are sandwiched between the flap 8 and the side cover 7, the configuration of the elastic body is not limited to the above. In the above embodiment, the flap 8 is configured in a substantially rectangular frame shape and is supported by the flap support portion 73 of the side cover 7, but the configuration of the base portion supporting the elastic body is not limited to the above. Figs. 11A and 11B are diagrams showing other examples of the elastic body and the base portion, and show modified examples of Figs. 10A and 10B. In the example of Figs. 11A and 11B, a pair of front and rear flaps 212 arranged with a gap 212a between them are fixed by rivets 213 to a pair of front and rear stays 211 arranged with a gap 211a between them. The stays 211 are fixed to the bottom of the roof console 210 shown by the two-dot chain line, for example.

[0050] The flap 212 is formed in a substantially plate-like shape, and the upper surface of the flap 212 is supported by a pair of front and rear pressing plates 214 arranged with a gap 214a in between. The gap 214a is longer than the diameter of the cap 14 and shorter than the gap 211a. The gap 212a is shorter than the diameter of the cap 14. When the movable shaft 101 passes through the gap 212a from above, the flap 212 is bent downward with the end of the stay 211 as a fulcrum P1, as shown in FIG. 11A. When the movable shaft 101 passes through the gap 212a from below, the flap 212 is bent upward with the end of the pressing plate 214 as a fulcrum P2, as shown in FIG. 11B. At this time, the fulcrum P2 is located inside the fulcrum P1 in the front-rear direction, that is, the gap 212a On the side 10A and 10B, the downward force F1 required to move the movable shaft 101 downward is greater than the upward force F2 required to move it upward.

[0051] In the above embodiment, the shade 1 is stored above the roof console 2, but the configuration of the storage section is not limited to that described above. The roof console 2 may be omitted, and the storage section may be formed by the upper cover 6 and the side cover 7. The shade unit 10 may be provided on the roof 200 adjacent to the window glass, without using the roof console 2. In the above embodiment, , possible Caps 14 are provided on both ends of the drive shaft 101 in the axial direction. Movable axisIn the above embodiment, the shade 1 is fixed to the fixed shaft 1. 2 to Although the shade 1 is configured as a roll shade that is rolled up, the configuration of the shade 1 is not limited to this. In the above embodiment, the spring 18 (biasing portion) is provided inside the fixed shaft 12, but the biasing portion may be provided at another position, such as a support portion of the fixed shaft 12. In the above embodiment, the stopper 19 (stop mechanism) is provided at the end of the fixed shaft 12, but the configuration of the stop mechanism is not limited to the above. In the above embodiment, the biasing force F0 of the spring 18 is set to a value larger than the necessary push-up force F2, but if the biasing force F0 is too large, a large effort is required when the user pulls the shade 1 downward. Therefore, in order to reduce the effort of the user, it is preferable to set not only the lower limit but also the upper limit of the biasing force F0. For example, the biasing force F0 may be set to a value smaller than the necessary push-down force F1.
