JP-A-5-199933

  In the above-described apparatus, since a gap is provided between the outer wall of the rail and the connecting pin of the shade, the connecting pin can move in the width direction of the shade within this gap. For this reason, when the shade is moved with respect to the rail, the shaft in the width direction of the shade is inclined with respect to the rail, and the position of the connecting pin of the shade with respect to the rail is not aligned vertically on each side of the shade in the width direction. Smooth movement may be hindered. In addition, because the shade is made of a soft material such as cloth, if the axis in the width direction of the shade is tilted with respect to the rail, wrinkles will occur at the end of the shade in the width direction, and the appearance (designability) of the shade will deteriorate. There is also a possibility to do.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a sunshade device that can ensure smooth movement of the shade and design.

  In order to solve the above problems, the technical means taken in the present invention is a sunshade device for opening and closing an opening of a ceiling member located below a roof panel of a vehicle as described in claim 1. A shade member that is wound in a cylindrical shape so as to open the opening, and is extended in a planar shape against a winding force to close the opening, and at each end in the vehicle width direction of the shade member. A shoe member provided; a rail member having an opposing wall portion facing in the vehicle width direction; and supporting the shoe member movably in the vehicle longitudinal direction between the opposing wall portions; and the shoe member. A holding portion that is pressed against one of the opposing wall portions by the elastic force in the vehicle width direction and holds the position of the shoe member with respect to the rail member against the winding force; and the shoe member, Opposite And a fitting part that is fitted between the parts and faces the holding part across one of the opposing wall parts, and slidably contacts the other opposing wall part in the vehicle longitudinal direction. is there.

  Preferably, as described in claim 2, the fitting portion of the shoe member may be in sliding contact with the opposing wall portion at least at each end portion in the vehicle front-rear direction.

  According to the first aspect of the present invention, the shoe member is provided with the fitting portion fitted between the opposing walls of the rail member. The fitting portion is opposed to the holding portion with one opposing wall portion therebetween, and is in sliding contact with the other opposing wall portion in the vehicle front-rear direction. In the above structure, since no gap is provided between the opposing wall portion of the rail member and the fitting portion of the shoe member, the shoe member does not move in the vehicle width direction with respect to the rail member. Therefore, when the shade member moves relative to the rail member, the shaft in the vehicle width direction of the shade member does not tilt with respect to the axis of the rail member, and the position of the shoe member relative to the rail member is on each side in the vehicle width direction. Always align in the longitudinal direction of the vehicle. Thereby, the loss of force when the shade member is moved relative to the rail member is reduced, and a smooth movement of the shade member is ensured. Moreover, since the shade member does not tilt with respect to the rail member, when the shade member is moved with respect to the rail member, wrinkles are not generated at the end portion of the shade member in the vehicle width direction. Thereby, the design property of a shade member is also ensured, without the appearance of a shade member falling.

  Furthermore, according to the second aspect of the present invention, the portion of the fitting portion of the shoe member excluding the end portions in the vehicle front-rear direction does not necessarily have to be in sliding contact with the opposing wall portion of the rail member. Thereby, the structure of the fitting part in a shoe member can be simplified.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view of an automobile roof 2 provided with a sunshade device 1 according to the present invention. A glass panel 2 b is provided on the roof panel 2 a that forms the roof 2. The glass panel 2b may be either a fixed type fixed to the roof panel 2a or a movable type moving with respect to the roof panel 2a. A ceiling member 3 is provided below the roof panel 2a. The ceiling member 3 forms part of the interior of the ceiling in the passenger compartment, and includes an opening 3a. The sunshade device 1 is for opening and closing the opening 3 a of the ceiling member 3. The sunshade device 1 opens and closes the opening 3 a of the ceiling member 3 below the glass panel 2 b of the roof 2. Thereby, the irradiation of the solar radiation into the vehicle interior via the glass panel 2a is adjusted.

  The sunshade device 1 includes a rail member 4, a shade member 5, and a roll member 6. The rail member 4 is provided on each side of the roof 2 in the left-right direction (vehicle width direction). The rail member 4 extends in the front-rear direction (vehicle front-rear direction). The shade member 5 is made of a soft material such as cloth and has a sheet shape. A handle portion 51 that is operated by an occupant is provided at the front end of the shade member 5. The shade member 5 is connected to the rail member 4 at an end portion of the handle portion 51 in the left-right direction, and is supported by the rail member 4 so as to be movable in the front-rear direction. The rear end of the shade member 5 is held by the roll member 6. The roll member 6 is a cylindrical member extending in the left-right direction, and is rotatably supported by the rail member 4. By this roll member 6, the shade member 5 is wound in a cylindrical shape so as to open the opening 3 a of the ceiling member 3, and is extended in a planar shape so as to close the opening 3 a of the ceiling member 3. The roll member 6 biases the shade member 5 in the winding direction (direction in which the shade member 5 is wound) by a biasing force of a biasing means (not shown) such as a torsion spring. Therefore, when the opening 3 a of the ceiling member 3 is closed, the shade member 5 is extended in a planar shape against the urging force (winding force) of the roll member 6.

  Next, the structure of the connecting portion 10 between the rail member 4 and the shade member 5 will be described with reference to FIGS. 2 is a perspective view showing the structure of the connecting portion 10 (enlarged view of the portion indicated by II in FIG. 1), FIG. 3 is a plan view showing the structure of the connecting portion 10, and FIG. 4 is the IV-IV line in FIG. FIG.

  A shoe member 52 is provided on the handle portion 51 of the shade member 5. The handle portion 51 supports the shoe member 52 movably in the left-right direction on each side in the left-right direction. The shoe member 52 is provided with a base portion 53, a fitting portion 54, and a holding portion 55. The base portion 53 forms a skeleton of the shoe member 52. An opposing vertical wall 53a is provided below the base member 53, and a groove 53b is formed between the opposing vertical walls 53a. A protrusion 51a provided in the handle portion 51 extending in the left-right direction is fitted into the groove 53b, so that the handle portion 51 is movable in the left-right direction with respect to the shoe member 52 and does not tilt in the front-rear direction. It is supported by. Since the handle portion 51 is supported so as to be movable in the left-right direction with respect to the shoe member 52, when the width of the rail member 4 provided on each side in the left-right direction of the roof 2 changes in the front-rear direction, the change is made. Can absorb. Thereby, it can prevent that the shade member 5 inclines with respect to the rail member 4. FIG. The shoe member 52 is supported by the handle portion 51 at the base portion 53. The fitting portion 54 is provided integrally with the base portion 53 and has a substantially block shape. The holding part 55 includes a coil spring 55a and a contact piece 55b. The coil spring 55a extends in the left-right direction. One end of the coil spring 55a is supported by the base portion 53, and the other end of the coil spring 55a is connected to the contact piece 55b. The contact piece 55b is urged in the left-right direction by the elastic force of the coil spring 55a.

  The rail member 4 includes opposing wall portions 41 and 42. The facing wall portion 41 faces the facing wall portion 42 in the left-right direction. The fitting portion 54 of the shoe member 52 is fitted between the opposing wall portions 41 and 42. The rail member 4 supports the fitting portion 54 of the shoe member 52 movably in the front-rear direction between the opposing wall portions 41 and 42. In this structure, the fitting portion 54 of the shoe member 52 is opposed to the contact piece 55b of the holding portion 55 with the opposing wall portion 41 therebetween, and is slidably contacted with the opposing wall portion 42 of the rail member 4 in the front-rear direction. The abutting piece 55b of the holding portion 55 is pressed against the opposing wall portion 41 of the rail member 4 in the left-right direction by the elastic force of the coil spring, and the opposing wall portion 41 is formed by the abutting piece 55b and the inner surface of the fitting portion 54. The position of the shoe member 52 (shade member 5) with respect to the rail member 4 is held against the winding force of the above-described roll member 6 by friction force by being pinched in the pressed state.

  The horizontal dimension between the opposing wall portions 41 and 42 in the rail member 4 is ideally set to be equal to the horizontal dimension of the fitting portion 54 in the shoe member 52. However, dimensional errors cannot be avoided. In the present embodiment, the gap in the left-right direction between the rail member 4 and the shoe member 52 is provided with a minimal gap (about zero to 0.5 millimeters). Thereby, the fitting part 54 of the shoe member 52 is always in contact with the opposing wall part 41 of the rail member 4, and is arranged in contact with the opposing wall part 42 or with a minimal gap.

  In addition, the site | part except the each edge part of the front-back direction among the fitting parts 54 of the shoe member 52 does not necessarily need to be in sliding contact with the opposing wall parts 41 and 42 of the rail member 4. FIG. Thereby, the structure of the fitting part 54 in the shoe member 52 can be simplified (for example, material saving, weight reduction, and cost reduction). That is, if the area where the fitting portion 54 of the shoe member 52 contacts the opposing wall portions 41 and 42 is reduced, the frictional resistance when the shade member 5 is moved along the rail member 4 is reduced, and the movement of the shade member 5 is reduced. It becomes smoother.

  As described above, according to the sunshade device 1 of the present invention, the shoe member 52 provided in the shade member 5 is provided with the fitting portion 54 that is fitted between the opposing walls 41 and 42 of the rail member 4. . The fitting portion 54 is opposed to the holding portion 55 with the opposing wall portion 41 interposed therebetween, and is in sliding contact with the opposing wall portion 42 in the front-rear direction. In this structure, there is no gap in the left-right direction between the opposing wall portions 41, 42 of the rail member 4 and the fitting portion 54 of the shoe member 52. Without moving in the left-right direction, the movement of the shoe member 52 in the left-right direction with respect to the rail member 4 is restricted. Therefore, when the shade member 5 moves in the front-rear direction with respect to the rail member 4, the left-right axis of the shade member 5 does not tilt with respect to the left-right axis of the rail member 4, so The position of the member 52 is always aligned in the front-rear direction on each side in the left-right direction. That is, the axis of the shade member 5 and the axis of the rail member 4 (the moving direction of the shade member 5) are parallel. As a result, the loss of force when the shade member 5 is moved along the rail member 4 is reduced, and the smooth movement of the shade member 5 is ensured.

  Furthermore, since the shade member 5 does not tilt with respect to the rail member 4, when the shade member 5 is moved with respect to the rail member 4, wrinkles are not generated at the left and right ends of the shade member 5. Thereby, the design of the shade member 5 is also ensured without deteriorating the appearance of the shade member 5.
