JP 2003-48433 A

  In the above-described apparatus, the driving force is transmitted from the first panel to the second panel by the inclined portion of the first panel pushing the connecting pin of the second panel. When the second panel is lifted upward with respect to the first panel by the lifting mechanism, the connecting pin slides on the inclined portion while being pressed against the inclined portion of the guide groove. In this structure, a large friction (sliding friction) acts between the connecting pin and the inclined portion. Due to this friction, there is a possibility that the movement (storage operation) in which the second panel is lifted upward with respect to the first panel may be hindered.

  Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a sunshade device that realizes a smooth storing operation.

  In order to solve the above-mentioned problems, the technical means taken in the present invention, as described in claim 1, is a ceiling member provided below a roof panel of a vehicle and provided with an opening, and the ceiling member A first panel that slides relative to the roof panel to open and close the opening; a second panel that slides upon receiving a driving force from the first panel to open and close the opening; and the second panel at a predetermined sliding position. A lifting mechanism that lifts the first panel upward with respect to the first panel, and a guide portion that is provided on the first panel and that movably guides the second panel lifted by the lifting mechanism with respect to the sliding direction of the first panel. A sunshade device for a vehicle comprising: the guide portion and the second panel, wherein the sunshade device is rotatably connected to the guide portion and the second panel. A link member and a rolling element that is held by the link member so as to be always in contact with the guide portion and rolls on the guide portion when the second panel is lifted upward with respect to the first panel by the lifting mechanism. It is set as the structure provided with these.

  Preferably, as described in claim 2, the rolling element is arranged on the guide portion when the first panel moves in the sliding direction via the guide portion with respect to the second panel that is lifted. It is good to roll.

  Preferably, as described in claim 3, a biasing member is provided between the link member and the second panel, and the biasing member rotates and biases the link member downward with respect to the second panel. good.

  Preferably, as described in claim 4, at least a portion of the rolling element that abuts on the guide portion may be formed of rubber.

  According to the first aspect of the present invention, when the second panel is lifted upward with respect to the first panel by the lifting mechanism, the rolling element held by the link member rolls on the guide portion of the first panel. . In this structure, rolling friction acts between the rolling elements and the guide portion. This is much smaller than sliding friction and does not hinder the movement (storage operation) in which the second panel is lifted upward relative to the first panel. In addition, since the rolling elements held by the link member are always in contact with the guide portion of the first panel, the first panel provided with the guide portion and the second panel connected to the link member rattle each other during the storing operation. Not stick. As described above, a smooth storing operation in the sunshade device is realized.

  According to the second aspect of the present invention, when the first panel moves in the sliding direction via the guide portion with respect to the lifted second panel, the rolling element held by the link member is placed on the guide portion. Roll. Accordingly, when the first panel moves in the sliding direction below the second panel, the first panel and the second panel do not rattle each other, and a stable operation in the sunshade device is ensured.

  According to the invention described in claim 3, the link member is rotationally biased downward with respect to the second panel by the biasing member provided between the link member and the second panel. In this structure, the first panel coupled to the link member via the guide portion is biased downward with respect to the second panel. That is, the second panel is biased upward with respect to the first panel. Thereby, the movement (storage operation) in which the second panel is lifted upward with respect to the first panel is assisted by the urging force of the urging member, and the storage operation in the sunshade device is performed more smoothly.

  According to the fourth aspect of the present invention, at least a portion of the rolling element that contacts the guide portion is formed of rubber. In this structure, the elasticity of the rubber further prevents rattling between the first panel and the second panel when the rolling element rolls on the guide portion, and the first panel and the second panel The operating noise generated during the period is reduced.

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

  FIG. 1 is a diagram schematically showing the structure of a slide sunshade 10 (vehicle sunshade device) according to the present invention. FIG. 2 is a cross-sectional view of the slide sunshade 10 (a cross-sectional view taken along the line II-II in FIG. 1).

  The slide sunshade 10 includes two panels 11 and 12. A ceiling member 14 is provided below the roof panel 13 of the vehicle.

The slide sunshade 10 shifts from the expanded state to the stored state through a predetermined storing operation described later.

  A slider 21 and a slider 22 are provided on each side edge of the panel 11 and the panel 12 in the left-right direction (one in each of FIGS. 3 and 4). These sliders 21 and 22 are supported by the guide rail 16.

  The guide rail 16 is provided with an upper groove 16a and a lower groove 16b that both extend in the front-rear direction. The upper groove 16a and the lower groove 16b are formed in a concave shape in the left-right direction. The upper groove 16a extends along the lower groove 16b above the lower groove 16b. An inclined portion 16c and an inclined portion 16b are provided at the rear ends of the upper groove 16a and the lower groove 16b, respectively. The inclined portion 16c and the inclined portion 16b (lifting mechanism) are formed in a concave shape in the left-right direction. The inclined portion 16c is provided continuously to the upper groove 16a and is inclined upward with respect to the upper groove 16a. The inclined portion 16b is provided continuously with the lower groove 16b and is inclined upward with respect to the lower groove 16a.

  The slider 21 (guide portion) slides in the front-rear direction within the lower groove 16 b of the guide rail 16. The panel 11 is supported by the guide rail 16 via the slider 21. A guide groove 21 a is formed in the slider 21. The guide groove 21 a extends along the guide rail 16 in the front-rear direction, that is, in the sliding direction of the panels 11 and 12. The guide groove 21a is formed in a concave shape in the left-right direction. The slider 21 is fixed to the drive shoe 17 (see FIG. 1). The driving force of the driving mechanism 19 (see FIG. 1) is transmitted to the panel 11 via the slider 21.

  The slider 22 is provided with a front support portion 22a and a rear support portion 22b. The front support portion 22 a slides in the front-rear direction within the upper groove 16 a of the guide rail 16. The rear support portion 22 a slides in the front-rear direction within the lower groove 16 b of the guide rail 16. The panel 12 is supported by the guide rail 16 via the slider 22.

  The connection link 20 (link member) is provided between the slider 21 and the slider 22 and connects the slider 21 and the slider 22. One end 20 a of the connection link 20 is connected to a guide groove 21 a formed in the slider 21. One end 20a of the connecting link 20 is rotatable with respect to the guide groove 21a and is slidable in the front-rear direction within the guide groove 21a. That is, the connecting link 20 is rotatably connected to the panel 11. The other end 20b of the connection link 20 is connected to the slider 22 via a support shaft 20c. The other end 20 b of the connecting link 20 is rotatable with respect to the slider 22. That is, the connecting link 20 is rotatably connected to the panel 12.

  In the connecting link 20, a roller 23 is provided between the one end 20a and the other end 20b. The roller 23 (rolling element) is rotatably supported by the connecting link 20. The roller 23 always contacts the slider 21 of the panel 11. A portion of the roller 23 that contacts the slider 21 is formed of a cushioning material (a material having a cushioning action) such as rubber. In the unfolded state of the slide sunshade 10 (shown in FIGS. 1 and 3), the roller 23 engages with the slider 21 in the front-rear direction.

  A spring 24 is provided between the connecting link 20 and the slider 22. The spring 24 (biasing member) is a known torsion spring (torsion spring) having a coil portion.

One end 24 a of the spring 24 is locked to the connecting link 20, and the other end 24 b is locked to the slider 22. The slider 22 constantly urges the connecting link 20 via the spring 24 so as to rotate counterclockwise as shown in FIG. 4 about the support shaft 20c. That is, the spring 24 urges the connecting link 20 to rotate downward (one direction) with respect to the slider 22.

  Hereinafter, the storing operation of the slide sunshade 10 will be described with reference to FIGS. FIGS. 6A to 6C are diagrams schematically illustrating the storing operation of the slide sunshade 10.

  FIG. 6A shows a developed state of the slide sunshade 10. In this state, the slider 21 of the panel 11 and the slider 22 of the panel 12 are arranged side by side in the front-rear direction (see FIG. 3). The slider 21 is supported by the lower groove 16 b of the guide rail 16. The slider 22 is supported by the upper groove 16a and the lower groove 16b of the guide rail 16 via the front support portion 22a and the rear support portion 22b, respectively. One end 20 a of the connecting link 20 is located at the rear end of the guide groove 21 a of the slider 21. The roller 23 held by the connecting link 20 is in contact with the slider 21.

  In the unfolded state shown in FIG. 6A, when the motor of the drive mechanism 19 (see FIG. 1) is supplied with power, the drive force generated by the motor is transmitted to the slider 21 via the drive shoe 17, and the slider 21 is Slide backward (to the right in FIG. 5) along the guide rail 16. At this time, the slider 22 also receives a driving force from the slider 21 and slides in the same direction (backward) along the guide rail 16 together with the slider 21.

  When the slider 21 and the slider 22 reach a predetermined slide position, the front support portion 22a and the rear support portion 22b of the slider 22 respectively enter the inclined portion 16c that continues to the upper groove 16a and the inclined portion 16d that continues to the lower groove 16b. The inclined portion 16c is inclined upward with respect to the upper groove 16a, and the inclined portion 16d is inclined upward with respect to the lower groove 16b. Therefore, as the slider 21 slides backward, the slider 22 is lifted upward with respect to the slider 21 while being pushed backward from the slider 21 as shown in FIG. While the slider 22 is lifted, one end 20 a of the connection link 20 rotates with respect to the slider 21 (guide groove 21 a), and the other end 20 b of the connection link 20 rotates with respect to the slider 22. Further, the roller 23 held by the connecting link 20 rolls on the slider 21 while being in contact with the slider 21.

  When the slider 21 slides further rearward in the state shown in FIG. 6B, the slider 22 is lifted further upward with respect to the slider 21. Accordingly, the connecting link 20 further rotates with respect to the slider 21 and the slider 22, and the roller 23 held by the connecting link 20 is detached from the slider 21 in the front-rear direction. At this stage, the slider 21 is slidable in the front-rear direction (the sliding direction of the first panel) with respect to the lifted slider 22 via the guide groove 21a. Therefore, when the slider 21 slides further backward with respect to the lifted slider 22, the slider 22 is overlaid on the slider 21 as shown in FIG. FIG. 6C shows the retracted state of the slide sunshade 10 (see FIG. 4). While the slider 21 slides below the lifted slider 22, the roller 23 held by the connecting link 20 rolls on the slider 21.

  In the above description, an example in which the glass panel 15a disposed above the opening 14a is fixed to the roof panel 13 is shown, but the present invention is not limited to this. For example, as shown in FIG. 7, even in a known sunroof device having a structure in which an opening 13a ′ formed in a roof panel 13 ′ is opened and closed by a glass panel 15a ′, that is, a movable glass panel 15a ′. The slide sunshade 10 of the invention can be applied.

  Further, although an example in which the spring 24 is provided between the connecting link 20 and the slider 22 has been shown, the spring 24 is not necessarily provided.

  As described above, according to the slide sunshade 10 of the present invention, when the panel 12 is lifted upward with respect to the panel 11 by the inclined portions 16 c and 16 d of the guide rail 16, the roller 23 held by the connecting link 20. However, it rolls on the slider 21 of the panel 11. In this structure, rolling friction acts between the roller 23 and the slider 21. This is much smaller than sliding friction, and does not hinder the movement (storage operation) in which the panel 12 is lifted upward with respect to the panel 11. Further, since the roller 23 held by the connecting link 20 is always in contact with the slider 21 of the panel 11, the panel 11 provided with the slider 21 and the panel 12 connected to the connecting link 20 are not in contact with each other during the storing operation. Absent. As described above, a smooth storing operation in the slide sunshade 10 is realized.

  Further, according to the present invention, the roller 23 held by the connecting link 20 rolls on the slider 21 when the panel 11 moves rearward via the slider 21 with respect to the lifted panel 12. Thereby, when the panel 11 moves rearward under the panel 12, the panel 11 and the panel 12 do not rattle each other, and a stable operation in the slide sunshade 10 is ensured.

  Further, according to the present invention, the connecting link 20 is urged to rotate downward with respect to the panel 12 by the spring 24 provided between the connecting link 20 and the panel 12. In this structure, the panel 11 connected to the connection link 20 via the slider 21 is urged downward with respect to the panel 12. That is, the panel 12 is urged upward with respect to the panel 11. Thereby, the movement (storage operation) in which the panel 12 is lifted upward with respect to the panel 11 is assisted by the urging force of the spring 24, and the storage operation in the slide sunshade 10 is performed more smoothly.

  According to the present invention, at least a portion of the roller 23 that contacts the slider 21 is formed of rubber. In this structure, the elasticity of the rubber further prevents rattling between the panel 11 and the panel 12 when the roller 23 rolls on the slider 21, and between the panel 11 and the panel 12. The generated operating noise (abnormal noise) is reduced.
