  Embodiments of the present invention will be described below. Of course, the following embodiments are merely examples of the present invention, and all the features shown in the embodiments are not necessarily essential to the means for solving the invention.

(1) Overview of this technology:
First, an overview of the present technology will be described with reference to FIGS. 1 to 12 are schematic diagrams, and the enlargement ratio in each direction shown in these diagrams may be different, and the diagrams may not be consistent.

  As a basic element, the winding device 1 has a screen 10, a winding portion 30 that urges the screen 10 in the storage direction D <b> 21, and a position P <b> 1 along the drawing end 20 of the drawn screen 10 at an interval. And a plurality of hook portions 50 fixed to a fixed object 101 (for example, a frame 104) of the vehicle. The screen 10 has a hooking portion 22 for hooking on the plurality of hook portions 50 at the drawing end 20. The hook portion 50 is elastically deformed in the storage direction D21 by a force applied in the storage direction D21 from the hook portion 22 at the final holding position P2 where the hook portion 22 that is hooked is finally held. An elastic part 80 is provided for allowing the hooking part 22 to move in the storage direction D21 while applying a repulsive force.

  When a relatively strong force (for example, force F21 shown in FIG. 9) from the hooking portion 22 of the screen 10 in the storage direction D21 is applied to the elastic portion 80 of the hook portion 50 at the final holding position P2, the elastic portion 80 is relatively large. The hook portion 22 of the screen 10 is held by the hook portion 50 in a state where the hook portion 22 of the screen 10 is relatively moved in the storage direction D21 due to elastic deformation. On the other hand, when a relatively weak force (for example, force F11 shown in FIG. 9) from the hooking portion 22 of the screen 10 in the storage direction D21 is applied to the elastic portion 80 of the hook portion 50 at the final holding position P2, the elasticity of the elastic portion 80 is increased. Deformation is relatively small, and the amount of movement of the hook portion 22 held by the hook portion 50 in the storage direction D21 is relatively small. It should be noted that the fact that the elastic deformation is relatively small includes not elastically deforming, and that the amount of movement is relatively small includes not moving.

  Here, the position of the hook part 50 fixed to the fixing object 101 varies, and the hook part 50 (for example, the hook part 50B shown in FIG. 10) fixed relatively to the drawing side of the screen 10 with reference to the design position in the storage direction D21. ) And a hook portion 50 (for example, a hook portion 50A shown in FIG. 10) relatively fixed to the storage side of the screen 10 is included in the plurality of hook portions 50. The hooking portion 22 (for example, the hooking portion 22B shown in FIG. 10) hooked by the hook portion 50 on the relatively pulling side has a relatively strong force (for example, a force F21 shown in FIG. 9) in the storage direction D21 at the final holding position P2. To the elastic part 80, the elastic part 80 moves relatively large in the storage direction D21 due to relatively large elastic deformation. On the other hand, the hooking portion 22 (for example, the hooking portion 22A shown in FIG. 10) hooked by the hook portion 50 on the relatively storage side has a relatively weak force (for example, the force shown in FIG. 9) in the storage direction D21 at the final holding position P2. Since only F11) is added to the elastic portion 80, the movement amount in the storage direction D21 is relatively small due to the relatively small elastic deformation of the elastic portion 80.

  As described above, in the storage direction D21, the shift of the hook portion 22 that is relatively hooked on the hook portion 50 on the drawer side from the design position of the hook portion 50 that is relatively hooked on the hook portion 50 on the storage side. And the difference is reduced. Therefore, the present technology can provide a winding device that can suppress the inclination of the screen that is hooked on the plurality of hook portions. On the other hand, in the comparative example shown in Japanese Patent Laid-Open No. 2000-52872, as shown in FIG. 13, the support shaft cannot move up and down at the final holding position of the support shaft. For this reason, if the plurality of hook-shaped holding portions fixed to the roof panel vary, the partition net is held in an inclined state. Note that the displacement lever attached to the holding portion is in the uppermost position in the state shown in FIG. 13, and an upward force cannot be applied to the support shaft.

Here, the screen is a concept including a shade, a blind, a sheet, and the like, and specifically includes a sunshade, a tonneau cover, and the like.
The drawer end of the screen is a portion having not only a strict leading edge of the screen but also a range in which the hook portion is included in the storage direction and the drawer direction of the screen. For example, when a garnish is formed in a part including the leading edge of the screen, this garnish is assumed to be included in the screen drawing end.
The final holding position is a position where the hook portion hooked on the hook portion stops moving in the screen orthogonal direction when the direction orthogonal to the drawn screen is the screen orthogonal direction (for example, the thickness direction D3 shown in FIG. 7). Means.
The elastic portion includes a spring, rubber, elastomer, and the like. The spring includes a leaf spring, a coil spring, and the like.

  By the way, the hook part 50 may have a body part 51 for guiding the hooked part 22 from the open end 65 toward the final holding position P2. The main body 51 may have a recess 66 that is recessed in the storage direction D21 so that the hook 22 can be inserted in the final holding position P2. The elastic portion 80 may contact the hook portion 22 in the recess 66. In this embodiment, since the hooking portion 22 hooked on the hook portion 50 is guided from the open end 65 toward the final holding position P2 and comes into contact with the elastic portion 80 in the concave portion 66, the screen hooked on the plurality of hook portions is arranged. A suitable structure that suppresses the tilt can be provided.

  The main body 51 may include a main member 60 in which the recess 66 is formed, and a sub member 70 attached to the main member 60. The elastic part 80 may be an elastic member 81 attached to the sub member 70. The recess 66 may be formed with an insertion portion 67 into which the sub member 70 is inserted in the direction in which the sub member 70 is attached to the main member 60 (sub member insertion direction D24). The main member 60 may include a fixing target engaging portion 61 a that engages with the fixing target 101. The sub member 70 inserted into the insertion portion 67 may reinforce the engagement between the fixing target engaging portion 61 a of the main member 60 and the fixing target 101. In this aspect, since the engagement between the fixing target engaging portion 61a of the main member 60 and the fixing target 101 is reinforced by the sub member 70 attached to the main member 60, the hook portion fixed to the fixing target is preferable. Structure can be provided. Of course, the present technology includes a case where the main body is not divided into a main member and a sub member.

  The elastic part 80 may be an elastic member 81 attached to the main body part 51. The main body 51 has an elastic member mounting portion 72 into which the elastic member 81 is inserted from a direction different from the storage direction D21 and the drawing direction D22 of the screen 10 (for example, the elastic member insertion direction D23 shown in FIG. 4). You may have. In this aspect, since the elastic member 81 can be inserted into the main body 51 from a direction different from the storage direction D21 and the drawing direction D22 of the screen 10, a suitable structure for attaching the elastic member to the main body can be provided. . Needless to say, the present technology includes a case where the elastic member is inserted into the main body from the storage direction or the drawing direction of the screen.

  The elastic portion 80 may have a convex portion 86 that is convex toward the hook portion 22 at the final holding position P <b> 2 and is in contact with the hook portion 22. In this aspect, since the convex portion 86 of the elastic portion 80 and the hook portion 22 are easily in contact with each other, it is possible to provide a suitable structure that suppresses the inclination of the screen that is hooked on the plurality of hook portions. Needless to say, the present technology includes a case where the elastic portion of the portion in contact with the hook portion in the final holding position is flat.

Reinforce the joint.

  The main member 60 and the sub member 70 can be molded products such as synthetic resin injection molded products. As this synthetic resin, thermoplastic resins such as polyamide, polypropylene (PP), polyacetal (POM), and polybutylene terephthalate (PBT) can be used. Additives such as reinforcing fibers may be added to these resins.

  The elastic member 81 (elastic portion 80) has a tilt suppressing function that balances the drawn screen 10. The elastic member 81 shown in FIGS. 4, 5, etc. is a leaf spring having a shape in which the fixed portion 83 and the movable portion 85 are folded back by the folded portion 82, and is attached to the elastic member mounting portion 72 of the sub member 70. The folded portion 82 of the elastic member 81 attached to the elastic member attaching portion 72 comes into contact with the back side wall portion 62 of the main member 60 when the sub member 70 is attached to the main member 60, and from the main member 60 to the sub member 70. So that it does not come off. The fixing portion 83 has notches 83a and 83a formed at both edges in the width direction D25, and an engagement hole 83h penetrating in the thickness direction in the middle portion of the width direction D25. When the elastic member 81 is inserted into the elastic member mounting portion 72 of the sub member 70, the fixing portion 83 is positioned in the width direction D25 by the positioning portions 72a and 72a. Further, when the notches 83a and 83a abut against the positioning portions 72a and 72a, the fixing portion 83 is positioned in the elastic member insertion direction D23, and the stopper 72s is fitted into the engaging hole 83h, so that the sub member 70 and the elastic member 81 are connected. Mating. The movable portion 85 comes into contact with the screen hooking portion 22 in the recess 66 of the main member 60 and can be elastically deformed in the storage direction D21 of the screen 10 with the folded portion 82 as the center. The movable portion 85 shown in FIG. 7 and the like has a convex portion 86 that bulges out in a substantially hemispherical shape from the flat surface toward the hook portion 22 at the final holding position P <b> 2 and contacts the hook portion 22 in the concave portion 66. . The top of the convex portion 86 shown in FIG. 7 is on the screen storage side with respect to the opening portion of the open end 65. In FIG. 7, a state where the movable portion 85 having the convex portion 86 is elastically deformed is indicated by a two-dot chain line. As shown in FIG. 7, since the convex portion 86 is convex toward the hook portion 22, the movable portion 85 and the hook portion 22 are easily brought into contact with each other, and the elastic member 81 exerts a repulsive force against the elastic deformation. It becomes easy to add to.

  The elastic strength (spring constant, etc.) of the elastic portion 80 is, for example, 0.8 compared to when the urging force applied from the winding portion 30 to the screen 10 is not applied when the hook portion 22 is applied to the elastic portion 80. About 3.0 mm (more preferably about 1.0 to 2.0 mm) can be set to the strength of elastic deformation. When only the gravity applied to the screen 10 is applied from the hooking portion 22 to the elastic portion 80, if the elastic portion 80 is not elastically deformed, the urging force applied from the winding portion 30 to the screen 10 is applied from the hooking portion 22 to the elastic portion 80. Sometimes, for example, the elastic strength of the elastic portion 80 may be set so as to be elastically deformed by about 0.8 to 3.0 mm (more preferably about 1.0 to 2.0 mm).

  The elastic member 81 can be a metal leaf spring, a synthetic resin leaf spring, a coil spring, or the like. In addition to the spring disposed below the screen hooking portion, the elastic portion may be a spring or the like whose main body portion is disposed above the screen hooking portion, such as a tension coil spring.

The hook part 50 can be assembled to the fixed object 101 as follows, for example. Of course, the assembling order can be changed as appropriate.
First, the fixing target engaging portion 61a of the main member 60 is inserted into the through hole 104h (see FIG. 7) of the frame 104, and the frame 104 and the fixing target engaging portion 61a are engaged. This engagement is a temporary engagement that is released when the main member 60 is pulled strongly from the frame 104. 4 and 5, the fixed portion 83 and the movable portion 85 of the elastic member 81 are inserted and attached to the elastic member attaching portion 72 of the sub member 70. Further, the sub member 70 is inserted into the insertion portion 67 of the main member 60 in the sub member insertion direction D <b> 24 and attached to the main member 60. At this time, the engagement assisting portion 78 of the sub member 70 is inserted into the through hole 61h of the drawer side wall portion 61 of the main member 60, and the engagement between the frame 104 and the fixing target engaging portion 61a is reinforced. As a result, even if the hook portion 50 is pulled strongly from the frame 104, it cannot be removed from the hole 104h. Further, the movable portion 85 of the elastic member 81 is disposed in the recess 66 of the main member 60, and the folded-back portion 82 of the elastic member 81 contacts the back side wall portion 62 of the main member 60, so that the sub member 70 is pulled out from the main member 60. It will not be.

The hook part 50 fixed to the fixed object 101 can be disassembled as follows, for example. Of course, the disassembly order can be changed as appropriate.
First, a tool is inserted into the groove 71a of the sub member 70, and the sub member 70 is pushed down with the tool as it is. Then, the folded portion 82 that has been in contact with the back side wall portion 62 goes out of the insertion portion 67 and the sub member 70 is detached from the main member 60. When the fixing portion 83 of the elastic member 81 attached to the sub member 70 is pushed backward, for example, by lifting it with a tool, the elastic member 81 is detached from the sub member 70. Further, when the main member 60 is pulled strongly from the frame 104, the main member 60 is detached from the frame 104.

  As shown in FIG. 1, when hook portions 50A and 50B are fixed to the frame 104 at intervals at a position P1 along the drawing end 20 of the screen 10 drawn out, the screen hooking portions 22A and 22B are fixed to the hook portions 50A and 50B. 22B can be hooked. At this time, for example, as shown in FIG. 8, when the screen hooking portion 22 is in the middle position P3 in contact with the bent portion 64 (in FIG. 8, the hooking portion 22 is shown by a two-dot chain line), The part 22 is guided from the open end 65 toward the final holding position P2. Then, as shown in FIG. 9, forces F11 and F21 from the hooking portion 22 in the screen storage direction D21 are applied to the elastic member 81 (elastic portion 80) at the final holding position P2.

  9 and 10 show the hook portion 50A fixed to the fixing object 101 when the distances in the storage direction D21 and the drawing direction D22 of the screen 10 from the winding portion 30 to the hook portions 50A and 50B are the same in design. , 50B illustrates the operation of the winding device 1 when the positions thereof vary. In the example shown in FIG. 10, the hook portion 50B is disposed at a distance LB1 that is relatively far from the winding portion 30, and the hook portion 50A is disposed at a relatively close distance LA1. The distances LA1 and LB1 are distances from the winding unit 30 to the screen catching units 22A and 22B when the elastic member 81 is not elastically deformed in the storage direction D21. If both hook portions 50A and 50B are fixed at the design position, LA1 = LB1, but in the example shown in FIG. 10, LA1 <LB1. FIG. 10 shows a state in which the edge portion 11b on the screen hooking portion 22B side of the both ends of the screen body portion 11 is stretched immediately before the elastic member 81 is elastically deformed in the storage direction D21 (state ST1). On the other hand, it is shown that the edge portion 11a on the screen hooking portion 22A side of the both edge portions of the screen main body portion 11 is in a wavy (loosened) state. In this case, as shown in the upper part of FIG. 9, a relatively strong force F21 is applied from the hooking portion 22B to the elastic member 81 at the final holding position P2, and a relatively weak force from the hooking portion 22A to the elastic member 81 at the final holding position P2. F11 is added. The force F21 applied from the hooking portion 22B includes a force that the urging portion 35 applies to the screen 10 in the storage direction D21 and a gravity that is applied to the screen 10 at the portion of the hooking portion 22B. The force F11 applied from the hooking portion 22A has gravity applied to the screen 10 in the portion of the hooking portion 22A, while there is little or no force applied by the biasing portion 35 to the screen 10 in the storage direction D21.

  As shown in the lower part of FIG. 9, the elastic member 81 to which a relatively strong force F21 is applied from the hook portion 22B is relatively elastically deformed and moves relatively large in the storage direction D21. Finally, the hook portion 22B is held by the hook portion 50B in a state where the force F22 (F22 <F21) applied from the hook portion 22B to the elastic member 81 and the repulsive force F42 applied from the elastic member 81 to the hook portion 22B are balanced. . On the other hand, the elastic deformation of the elastic member 81 to which a relatively weak force F11 is applied from the hook 22A is relatively small, and the amount of movement of the hook 22A in the storage direction D21 is relatively small. Finally, the hook portion 22A is held by the hook portion 50A in a state where the force F12 (F12 <F11) applied from the hook portion 22A to the elastic member 81 and the repulsive force F32 applied from the elastic member 81 to the hook portion 22A are balanced. . In the lower part of FIG. 9, the positions of the hook portions 22A and 22B immediately before the elastic member 81 is elastically deformed in the storage direction D21 are indicated by a two-dot chain line.

  As shown in FIG. 10, the hooking portion 22B hooked on the hook portion 50B that is relatively far from the winding portion 30 applies a relatively strong force F21 in the storage direction D21 to the elastic member 81 at the final holding position P2. It moves relatively large in the storage direction D21. The lower part of FIG. 10 shows that the distance from the winding part 30 to the hooking part 22B has been shortened to LB2 (LB2 <LB1). On the other hand, the hooking portion 22A hooked on the hook portion 50A that is relatively close to the winding portion 30 applies only a relatively weak force F11 in the storage direction D21 to the elastic member 81 at the final holding position P2, so that the hooking portion 22A moves to the storage direction D21. The amount of movement is relatively small. The lower part of FIG. 10 shows that the distance from the winding part 30 to the hooking part 22B is LA2. In the upper part of FIG. 10, the position of the garnish 21 after movement is indicated by a two-dot chain line. 10, the position of the elastic member 81 immediately before the elastic member 81 is elastically deformed in the storage direction D21 is indicated by a two-dot chain line.

As shown in the final state ST2 in FIG. 10, in the storing direction D21, the distance from the winding portion 30 of the hook portion 22B hooked to the relatively far hook portion 50B and the hook hooked to the relatively close hook portion 50A. The difference between the distance from the winding portion 30 of the portion 22A is small. Therefore, the winding device 1 can suppress the screen hooked on the plurality of hook portions from being tilted from the design position, and can improve the appearance of the screen 10.
In the design, when the hook portions 50A and 50B are fixed so that the force applied to the elastic portion 80 from the hook portion 22 hooked at a position where the distance from the winding portion 30 is different is fixed, “(1) As described in “Technical overview”, the operation can be described with reference to the design positions of the hook portions 50A and 50B.

(3) Modification:
Various modifications can be considered for the present invention.
The sunshade device can be installed on a side window, a rear window, a roof window, a front window, and the like. In addition to the upper direction, the screen pull-out direction may be lower, left, right, front, rear, etc. In addition to the sunshade device, the take-up device may be a tonneau cover device, a partition device that partitions the interior of the vehicle in the front-rear direction, and the like.
The hook portion may be fixed to a body panel other than the frame, an interior material, or the like.

The hooking portion of the screen may be a recessed hole that does not penetrate, a portion that protrudes from the edge of the screen, or the like other than the through hole.
The hook portions may be fixed to three or more places to be fixed at intervals along the drawing end of the drawn screen. Also in this case, the effect which suppresses the inclination of the screen hooked on a some hook part by the same effect | action is acquired.
The convex part of the elastic part has a substantially semi-cylindrical shape that bulges or protrudes into a substantially polygonal column shape such as a substantially quadrangular prism, or a garnish longitudinal direction D2 in addition to a substantially hemispherical shape. A bulging shape or the like may be used. In addition, even if the elastic portion in contact with the screen hooking portion is flat, such as a flat surface, the basic effect of the present technology can be obtained.
The elastic portion may be formed integrally with the main body portion in addition to the elastic member different from the main body portion 51 of the hook portion.

FIG. 11 and FIG. 12A show a modification of the hook portion 50. In the drawings showing the modified examples, the same reference numerals are given to the same portions as the specific examples shown in FIGS.
The elastic part 80 of the hook part 50 of this modification has a plate-shaped resin spring part 180 integrally formed with the main body part 51. The resin spring portion 180 extends from the end portion 181 connected to the bent portion 64 of the main body portion 51 toward the back side wall portion 62. The material of the resin spring portion 180 may be the same as the material of the main body 51 or may be different from the material of the main body 51. Further, the main body 51 integrally formed with the resin spring portion 180 is fixed by inserting an engagement assisting member 178 instead of the engagement assisting portion 78 shown in FIG. 4 or the like into the hole 61 h of the drawer side wall portion 61. It is assumed that the engagement between the target engaging portion 61a and the fixed target is assisted and fixed to the fixed target.

  When the screen hooking portion 22 is hooked on the hook portion 50 having the resin spring portion 180, the hooking portion 22 is guided from the open end 65 toward the final holding position P2. Then, a force in the screen storage direction D21 from the hooking portion 22 is applied to the resin spring portion 180 at the final holding position P2, and the tip end portion 182 moves in the storage direction D21 with the end portion 181 as a fulcrum as shown by a two-dot chain line in FIG. The resin spring portion 180 is elastically deformed so as to move. Here, as shown in FIG. 9, the hook portion (hanging portion 22 </ b> B) hooked on the hook portion 50 on the relatively drawer side moves relatively large in the storage direction D <b> 21, and the hook portion on the relatively storage side. The amount of movement in the storage direction D21 is relatively small for the hooking portion 22 (referred to as hooking portion 22A) hooked by 50. Therefore, in the storage direction D21, the difference between the design position of the hook portion 22B that is relatively hooked on the hook portion on the drawer side and the shift from the design position of the hook portion 22A that is relatively hooked on the hook portion on the storage side. The difference is reduced. Therefore, also in this modification, it is possible to suppress the inclination of the screen hooked on the plurality of hook portions.

The repulsive force applied from the resin spring part 180 to the hooking part 22 can be adjusted by changing the shape, material, etc. of the resin spring part 180. For example, when the resin spring portion 180 is thickened, the repulsive force of the resin spring portion 180 is increased, and when the resin spring portion 180 is thinned, the repulsive force of the resin spring portion 180 is weakened.
Further, when the resin spring portion 180 is divided into a plurality of resin spring portions 180A, 180B, and 180C as in the modification shown in FIG. 12B, the repulsive force of the resin spring portion 180 can be weakened. The side surface of the hook part 50 of this modification is the same as that of the hook part 50 shown in FIG. 11, and the resin spring parts 180 </ b> A to 180 </ b> C extend from the end part 181 connected to the bent part 64 toward the back side wall part 62. I'm out.

  It should be noted that even if a winding device without a case or the like is provided as long as there is a screen having a hooking portion at the drawer end, a winding portion for biasing the screen in the storing direction, and a plurality of hook portions having an elastic portion, Effects can be obtained.
