Description

  The present invention relates to a take-up shade device used for a vehicle sunroof device and the like.

  For example, as a sunroof device for a vehicle, a structure having a translucent window that closes an opening formed in a roof portion with a translucent panel, and a wind-up shade device for shielding light on the indoor side There is.

  And if the retractable shade device is opened simultaneously with the panel, the opening of the roof is opened and the lighting can be obtained, and the interior ventilation and the feeling of opening are obtained. If only the take-up type shade device is opened, it can be lit in the vehicle through the panel, and only the sense of opening can be enjoyed.

  In general, since the roof portion of the vehicle is appropriately curved with a curvature, the translucent window is also curved in accordance with the roof portion. On the other hand, the winding shaft on which the sheet-like shade fabric of the winding-type shade device is wound is usually made of a linear rigid body, and in the closed state where the shade fabric is pulled out, the winding shaft is curved. Inside the translucent window, the shade fabric was placed in a flat shape.

  For this reason, there is a disadvantage that a feeling of pressure is generated because an unnecessarily large clearance is formed between the curved translucent window and the flat shade fabric, and the indoor space is narrowed.

  Therefore, as a structure for reducing the clearance between such a translucent window and the winding-type shade device disposed on the inside thereof, the operation of pulling out the shade fabric with the winding shaft curved is performed. There has been proposed an apparatus that can perform a rewinding operation (see, for example, Patent Document 1).

  The winding-type shade device 10 has a winding shaft 12 biased in a winding direction by a coil spring 11, and one end portion attached to the winding shaft 12, and winding is performed by rotation of the winding shaft 12 in the winding direction. Covers the rectangular sheet-shaped shade 13 made of a light-shielding cloth or the like wound around the take-up shaft 12, the operation stay 14 attached to the end of the shade 13 on the drawer side, and the take-up shaft 12 around which the shade 13 is taken up The shape-retaining cover holder 15 and a transparent translucent guide panel 16 that guides and supports the shade 13 are provided on the indoor side of the shade 13 to which the shape-retaining cover holder 15 is attached and pulled out. It is structured.

  As shown in FIGS. 1 and 2, the take-up shaft 12 has a rigid pipe body 18 having a rigidity made of a metal pipe, a hard resin pipe, or the like, and a flexible deformation body made of a soft resin pipe, a rubber tube, or the like. The flexible pipe bodies 19 are alternately arranged, and a cylindrical shaft member is integrally connected by a heat shrinkable tube 20 covering the pipe bodies 18 and 19.

  At this time, the rigid pipe body 18 and the flexible pipe body 19 are pipes having the same diameter, and each has an appropriate length. In the present embodiment, the rigid pipe body 18 is provided at both ends and the center of the winding shaft 12. Are arranged, and a flexible pipe body 19 is disposed between the rigid pipe bodies 18 to form a bilaterally symmetric structure.

  Here, the winding shaft 12 can be bent and deformed at the flexible pipe body 19 portion, and the winding shaft 12 having flexibility as a whole is configured.

  The coil spring 11 is accommodated in the winding shaft 12, and one end of the coil spring 11 is fixed to the inner surface of the rigid pipe body 18 at the center via the spring holder 22. Is fixed to one of the support holders 23 and 24 that rotatably supports both ends of the winding shaft 12. That is, with one end of the coil spring 11 being locked in the locking hole 22 a of the spring holder 22, the coil spring 11 is press-fitted into the central rigid pipe body 18 to be in a fixed state. One end of the support holder 23 is locked in a locking hole 23 b formed in the support shaft 23 a to be in a fixed state, and the winding shaft 12 is relatively moved by the biasing force stored in the coil spring 11. It is set as the structure which always energizes to a winding direction.

  The coil spring 11 is housed in the take-up shaft 12 with a flexible soundproof tube 25 made of rubber, soft resin, or the like, and both ends of the take-up shaft 12 are bushed. The support shafts 23a and 24a of the support holders 23 and 24 are rotatably supported via 26. And each support holder 23 and 24 is set as the structure fixed to the translucent guide panel 16 by fixing parts, such as a screw, respectively.

  The translucent guide panel 16 is made of a transparent resin molded body or the like, and has a curvature corresponding to the curved shape of the roof glass 4 so as to be arranged substantially parallel to the curved roof glass 4. The shape retaining cover holder 15 attached along the width direction to the rear end portion of the translucent guide panel 16 is also formed in a curved shape having a curvature corresponding to the curved shape of the roof glass 4. And the outlet 15a of the shade 13 pulled out from the shape-retaining cover holder 15 is also configured in a curved shape having the same curvature. In addition, the structure comprised only with the shape-retaining cover holder 15 or the structure comprised with the shape-retaining cover holder 15 and the translucent guide panel 16 may be sufficient as this outlet 15a.

  This shape-retaining cover holder 15 has a structure in which an extrusion mold material extruded by a metal material, for example, aluminum is formed in a curved shape. Here, the take-up shaft 12 around which the shade 13 accommodated and held in the shape-retaining cover holder 15 is taken up is formed by the shape-restricting action of the shape-retaining cover holder 15, as in the shape-retaining cover holder 15 It is structured to be held rotatably in a curved form.

  Further, the operation stay 14 is made of a metal material, for example, an extrusion mold material extruded by aluminum, and the operation stay 14 is also formed in a corresponding curved shape like the shape retaining cover holder 15. At the center in the width direction of the guide panel 16, a through-hole 16a through which the operation portion 14a disposed in a downward projecting shape at the center in the width direction of the operation stay 14 can pass is formed in a long and narrow shape in the front-rear direction. Yes.

  The shade 13 is pulled out or rewound from the shape retaining cover holder 15 by operating the operating stay 14 back and forth. At this time, the drawn-out shade 13 is held in a curved shape by the tension by the urging force of the coil spring 11 in the winding direction, and is also held in a curved shape by the translucent guide panel 16 located on the indoor side. . In addition, corresponding to the front end operation position of the operation stay 14, stay holding portions 16 b that releasably hold the operation stay 14 are provided on both sides of the front end portion of the translucent guide panel 16. In the present embodiment, as shown in FIG. 4, the front end portion of the shade 13 is connected to a predetermined position of the operation stay 14 via a core rod 28 having a length in the width direction. ing.

  The present embodiment is configured as described above. Normally, the operating stay 14 is in the unfolded state of the shade 13 held by the stay holding portion 16b, and when lighting is necessary, the stay holding of the operating stay 14 is maintained. By releasing the holding by the portion 16b and moving it backward, the shade 13 may be taken up by the take-up shaft 12 in the shape-retaining cover holder 15. Further, in the case of shielding light, if the operation stay 14 is moved forward, the shade 13 is sequentially pulled out, and the operation stay 14 may be held by the stay holding portion 16b.

  When the take-up shaft 12 is rotated during the operation of pulling out or rewinding the shade 13, the take-up shaft 12 is formed by the flexible pipe body 19, which is a constituent part of the take-up shaft 12 due to the shape regulating action of the shape-retaining cover holder 15. The shape-retaining cover holder 15 is deformed appropriately and is constantly deformed into a predetermined arc shape along the curved shape of the shape-retaining cover holder 15.

  As described above, the winding shaft 12 has a structure in which each flexible pipe body 19 portion, which is a flexible portion, is bent and deformed at the time of rotation so that the winding shaft 12 is continuously deformed along the shape of the shape-retaining cover holder 15. Therefore, the winding shaft 12 can be effectively held in a curved state along the roof glass 4, and flapping of the winding shaft 12 during the operation of the shade 13 can be effectively prevented. This eliminates the need for a conventional curved fixed shaft and a large number of flanges attached to the fixed shaft, reduces costs by reducing the number of parts, and simplifies the structure, improving assembly and making it more compact. There is an advantage that can be achieved.

  Further, since the winding shaft 12 is configured to be rotatably held in a curved state, the winding-type shade device 10 can be configured in a state along the curvature of the roof glass 4, and the roof glass 4 and the winding-type shade device can be configured. There is an advantage in that a useless space between 10 can be reduced and an internal space in the vehicle can be effectively ensured to the maximum.

  Further, when the shade 13 is opened and closed by the operation stay 14, the guide 13 at the peripheral edge of the curved outlet 15 a in the shape-retaining cover holder 15 can be used to make the orbit of the shade 13 constant or to generate wrinkles in the shade 13. There is an advantage that an effect that can be suppressed can be exhibited.

  Further, since the operation stay 14 and the shape retaining cover holder 15 are also formed in corresponding curved shapes similar to the roof glass 4 and the translucent guide panel 16, the unfolded shade 13 is wound around the winding shaft 12. Due to the urging force in the take-up direction, the take-up shaft 12 and the operation stay 14 are bent along the roof glass 4 with a predetermined tension. At this time, since the light-transmissive guide panel 16 having a curved shape with the same curvature is disposed on the indoor side of the shade 13, the light-transmitting light is transmitted during the pull-out operation, the rewind operation, and the unfolded state of the shade 13. Since the sex guide panel 16 guides and supports the shade 13 from the indoor side, the shade 13 can be effectively guided and held in a desired curved shape.

  Further, since the transparent guide panel 16 is formed with a through-hole 16a through which the operation portion 14a of the operation stay 14 can pass in the operation direction, the shade 13 is formed by the operation portion 14a protruding from the through-hole 16a to the indoor side. The drawing operation and the rewinding operation can be easily performed, and there is an advantage that it can be provided with a simple configuration.

  Further, the parts constituting the winding shaft 12 such as the alternately arranged pipe bodies 18 and 19 are covered with the heat shrinkable tube 20 and are connected and integrated by heat shrinking, and are easily connected and integrated. The winding shaft 12 can be configured.
