<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. In this embodiment, the sunshade apparatus 30 which can cover the rear window glass 11 of the vehicle 9 is illustrated. As shown in FIG. 1, a package tray 10 is disposed at the rear of the vehicle 9 (an example of a vehicle), and a rear window glass 11 is disposed above the package tray 10. The rear window glass 11 is arranged between the pillar garnishes 12 and 12, and is inclined so as to be directed upward of the vehicle toward the front of the vehicle. Further, the rear window glass 11 has a trapezoidal shape in which the upper end is shorter than the lower end, as indicated by a two-dot chain line in FIG.

  FIG. 2 is a view of the sunshade device 30 as viewed from the vehicle compartment outside (vehicle rear side). As shown in FIG. 2, the sunshade device 30 winds a trapezoidal shade 31 that can cover the rear window glass 11, a base member 32 that is long in the vehicle width direction (left-right direction in FIG. 2), and the shade 31. A take-up shaft 33 that can be taken, a frame 50 that is attached to the upper end portion 31A of the shade 31 (a peripheral end portion opposite to the take-up shaft in the shade, the upper bottom of the shade), and a longitudinal opening 10A. The package tray 10 (board member) which has and the moving apparatus 40 which moves the flame | frame 50 up and down along the surface by the side of the vehicle interior of the rear window glass 11 are provided. The opening 10A extends in the vehicle width direction and can accommodate the frame 50. Components that will be described later are mainly attached to the base member 32.

  The shade 31 is a flexible sheet-like member, for example, a translucent sheet, an opaque sheet, a mesh sheet, a woven fabric, a non-woven fabric, or the like. Examples of the material of the shade 31 include synthetic resin materials such as polyvinyl chloride and polypropylene, but are not limited thereto. The winding shaft 33 has a cylindrical shape that is long in the vehicle width direction, and is attached to the base member 32 so as to be housed inside the base member 32 as shown in FIG. The take-up shaft 33 is attached so as to be rotatable about the axis of the take-up shaft 33, and the lower end portion of the shade 31 is attached to the take-up shaft 33. The take-up shaft 33 is urged by a built-in coil spring (not shown) so as to rotate in the direction in which the shade 31 is taken up.

  In the present embodiment, the frame 50 is moved up and down by the moving device 40, and the shade 31 moves between the deployed state covering the rear window glass 11 and the inside of the base member 32 by moving the frame 50 up and down. It can be changed between the accommodation states to be accommodated. As shown in FIG. 2, the winding shaft 33 and the base member 32 are arranged below the package tray 10 (the cross section is hatched in FIG. 2), and the shade 31 passes through the opening 10 </ b> A of the package tray 10. It is configured to be taken in and out.

  As shown in FIG. 2, the moving device 40 includes a motor 41, a link lever 42, links 43A and 43B, and arms 45A and 45B. For example, the link lever 42 is rotatably attached to the base member 32 and is configured to be rotated by driving the motor 41. One end of the link 43A and one end of the link 43B are rotatably attached to the outer peripheral end of the link lever 42, respectively.

  The arm 45A connects the link 43A and the frame 50, and is divided by an upper arm 46A and a lower arm 47A. The arm 45B connects the link 43B and the frame 50, and is divided by an upper arm 46B and a lower arm 47B. The lower arm 47A is rotatably attached to the base member 32 and is attached to the other end of the link 43A at one end in the longitudinal direction. One end portion of the upper arm 46A is rotatably attached to the other end portion of the lower arm 47A, and the other end portion of the upper arm 46A is rotatable relative to a frame main body portion 51 (described later) of the frame 50. It is attached.

  The lower arm 47B is rotatably attached to the base member 32, and is attached to the other end of the link 43B at one end in the longitudinal direction. One end of the upper arm 46B is pivotably attached to the other end of the lower arm 47B, and the other end of the upper arm 46B is pivotally attached to the frame main body 51 of the frame 50. Yes.

  When the motor 41 is driven in a state where the shade 31 of FIG. 2 is deployed and the link lever 42 is rotated clockwise (in the direction indicated by the arrow R1 in FIG. 2), the link 43A and the link 43B are respectively linked to the link lever 42. Slide away from the side (directions indicated by arrows R2 and R3 in FIG. 2). As a result, the lower arm 47A rotates counterclockwise in FIG. 2 (the direction indicated by the arrow R4 in FIG. 2), and the lower arm 47B rotates clockwise in the FIG. 2 (the direction indicated by the arrow R5 in FIG. 2). To do.

  In conjunction with this, the upper arm 46A rotates so as to overlap the lower arm 47A, and the upper arm 46B rotates so as to overlap the lower arm 47B (indicated by a two-dot chain line in FIG. 2). As a result, the frame 50 slides (lowers) so as to approach the take-up shaft 33, and the shade 31 enters the accommodated state. In the state where the shade 31 is accommodated, as shown in FIG. 5, the frame 50 is fitted into the opening 10A of the package tray 10 and closes the opening 10A. As described above, in the present embodiment, by driving the motor 41, the arms 45A and 45B rotate with respect to the base member 32, and the arms 45A and 45B are folded, so that the frame 50 is on the base member 32 side. It is configured to approach (winding shaft 33 side). Then, in conjunction with the approach of the frame 50 toward the winding shaft 33, the shade 31 is wound up by the winding shaft 33 and accommodated inside the base member 32.

  Further, in the case where the shade 31 in the accommodated state is brought into the unfolded state (the arms 45A and 45B are extended to the maximum), the motor 41 is driven and the link lever 42 is rotated counterclockwise (indicated by an arrow R6 in FIG. ). As a result, the links 43A and 43B and the arms 45A and 45B operate in the opposite direction to that when the shade 31 is accommodated, and the folded arms 45A and 45B are deployed, respectively. As a result, the frame 50 moves away from the winding shaft 33 side. Slide to the side (rise). When the frame 50 moves away from the take-up shaft 33 side, the shade 31 is deployed against the urging force of the take-up shaft 33 and enters a developed state.

  As shown in FIG. 2, in the present embodiment, the shade 31 has a trapezoidal shape in order to more reliably cover the trapezoidal rear window glass 11. Further, the length of the frame 50 needs to be set smaller than the length of the upper end portion of the rear window glass 11 in order to avoid interference with the pillar garnish 12, 12 or the like. On the other hand, the length of the opening 10A needs to be set to a value closer to the length of the lower bottom of the shade 31. For this reason, if the unfolded frame 50 is accommodated in the opening 10A as it is, the length of the frame 50 is insufficient compared to the length of the opening 10A, and the opening 10A is attached to the frame 50. Can not be blocked enough. For this reason, the frame 50 of the present embodiment is configured to be able to expand and contract in the longitudinal direction in conjunction with the vertical movement.

  Next, the configuration of the frame 50 will be described. 4 is a cross-sectional view showing one end portion of the frame 50 in a state where the shade 31 is unfolded (a state where the shade 31 covers the entire rear window glass 11), and FIG. 5 is a state where the shade 31 is accommodated in the opening 10A. 3 is a cross-sectional view showing one end portion of a frame 50. FIG. In the following description, the position of the frame 50 in FIGS. 3 and 4 is referred to as a developed position, and the position of the frame 50 in FIG. 5 is referred to as an accommodation position.

  The frame 50 has a longitudinal shape along the upper end portion 31A (circumferential end portion) of the shade 31, and as shown in FIG. 2, a longitudinal frame main body portion 51 attached to the upper end portion 31A of the shade 31, Slide parts 52A and 52B, which are respectively attached to both ends of the frame body 51 in the direction. As shown in FIG. 3, the slide portions 52 </ b> A and 52 </ b> B are extrapolated to the end portions of the frame main body portion 51, respectively. The slide is movable. The pair of slide portions 52A and 52B slide relative to the frame main body portion 51, whereby the frame 50 is configured to be extendable and contractable in the longitudinal direction.

  Rollers 61 are attached to both ends of the frame main body 51. The roller 61 is attached to be rotatable about an axis along the longitudinal direction of the frame main body 51 (the left-right direction in FIG. 2 and the direction orthogonal to the moving direction of the frame 50). As shown in FIG. 3, when the frame 50 moves up and down along the rear window glass 11, the roller 61 comes into contact with the rear window glass 11.

  In this embodiment, the inclination angle (inclination angle with respect to the horizontal direction) of the arms 45A and 45B (for example, the arm 45A is shown in FIG. 3) in the natural state (the state where the rear window glass 11 is not disposed) It is set to be larger than the inclination angle, and when the roller 61 is in contact with the rear window glass 11, the arms 45A and 45B are slightly bent from the natural state. For this reason, the roller 61 is configured to be pressed against the rear window glass 11 mainly due to the elastic restoring force of the arms 45A and 45B. Thereby, the frame 50 can be held in the unfolded state, and for example, it is possible to suppress a situation where the frame 50 vibrates when the vehicle travels.

  In the process in which the frame 50 moves up and down, the roller 61 pressed against the rear window glass 11 rotates to reduce the friction generated between the roller 61 and the rear window glass 11. In the present embodiment, the roller 61 and the rear window glass 11 are separated from each other in the initial stage of the process in which the frame 50 moves from the housing position to the deployed position, and the roller 61 moves in the middle of the frame 50 toward the deployed position. After the contact with the rear window glass 11, the roller 61 is configured to reach the unfolded position while rotating. In the initial stage of the process of moving the frame 50 from the deployed position to the storage position, the roller 61 is in contact with the rear window glass 11, and the roller 61 is separated from the rear window glass 11 while the frame 50 is moving toward the storage position. It is the composition to do.

  In the present embodiment, each of the pair of slide portions 52A and 52B slides in conjunction with the rotation of each of the pair of rollers 61 and 61. Next, the motion converting mechanism 60 that converts the rotational motion of the roller 61 into the linear motion of the slide portions 52A and 52B (the expansion and contraction motion of the frame 50) will be described by exemplifying the slide portion 52A. As shown in FIG. 4, the motion conversion mechanism 60 includes a female screw 61B formed on the roller 61, and a shaft member 62 interposed between the roller 61 and the slide portion 52A.

  A through hole 61A is formed at the center of the roller 61, and a female screw 61B is formed on the inner peripheral surface of the through hole 61A. One end of the shaft member 62 is inserted through the through hole 61A. One end of the shaft member 62 is formed with a male screw 62B that is screwed into the female screw 61B. The other end portion of the shaft member 62 is attached to the slide portion 52A. The roller 61 is fixed in the longitudinal direction of the frame 50. Thus, when the roller 61 rotates, the shaft member 62 is advanced and retracted via the female screw 61B (roller side screw portion) and the male screw 62B (slide portion side screw portion). In other words, the rotational movement of the roller 61 is converted into the linear movement of the shaft member 62 (and eventually the sliding movement of the sliding portion 52A).

  In the present embodiment, as shown in FIG. 3, in the process of lowering the frame 50 (the process of moving from the deployed position to the receiving position, the moving direction of the frame 50 is indicated by the arrow P1 in FIG. 3) It is configured to rotate clockwise (see arrow R7 in FIG. 3). The female screw 61B and the male screw 62B are configured to push the shaft member 62 outward when the roller 61 rotates counterclockwise (right screw in this embodiment). With such a configuration, when the roller 61 rotates counterclockwise, the slide portion 52A slides in the direction away from the frame main body portion 51 (the direction indicated by the arrow P2 in FIG. 4), and the frame 50 The total length of becomes larger. The motion conversion mechanism related to the slide part 52B has the same configuration as the motion conversion mechanism 60 related to the slide part 52A except that it is bilaterally symmetric, although not shown. That is, the female screw and the male screw related to the slide part 52B are set in the opposite direction (left screw) to the female screw 61B and the male screw 62B related to the slide part 52A. The rotation amount of the roller 61 is proportional to the advance / retreat amount of the slide portion 52A (or the slide portion 52B). By appropriately setting the number of threads of the female screw 61B and the male screw 62B, the rotation amount of the roller 61 is adjusted. The advance / retreat amount of the slide part 52A (or the slide part 52B) can be set.

  Next, the operation of this embodiment will be described. In the process in which the frame 50 moves from the deployed position (see FIGS. 3 and 4) to the accommodated position (see FIG. 5) by the operation of the moving device 40 described above, the rollers 61 and 61 are in contact with the rear window glass 11. Rotate counterclockwise. As a result, the slide parts 52A and 52B slide and move away from the frame main body part 51, respectively, and the overall length of the frame 50 increases. As a result, as shown in FIG. 5, the frame 50 can be extended compared to the deployed position at the storage position, and the opening 10 </ b> A can be more reliably closed by the frame 50.

  In the process of moving the frame 50 from the storage position to the deployed position, the rollers 61 and 61 abut against the rear window glass 11 while the frame 50 is moving toward the deployed position. Rotate around. As a result, the slide parts 52A and 52B slide in the direction approaching the frame main body part 51, respectively, and the overall length of the frame 50 is reduced.

  Next, the effect of this embodiment will be described. According to the present embodiment, the rotational movement of the roller 61 can be converted into the expansion / contraction movement of the frame 50, and the total length thereof can be increased. Temporarily, when it is set as the structure which transmits the motive power of the drive device (for example, motor 41 etc.) which operate | moves the flame | frame 50 directly to the flame | frame 50, and expands and contracts the flame | frame 50, it is necessary to provide a power transmission mechanism between the flame | frame 50 and a drive device. There is a complicated configuration. On the other hand, according to the present embodiment, the motion conversion mechanism 60 related to the expansion and contraction motion of the frame 50 can be disposed between the frame 50 and the roller 61, and a simpler configuration can be achieved. Further, the frame 50 can be stabilized by bringing the roller 61 into contact with (pressing against) the rear window glass 11.

  The frame 50 is provided at a longitudinal frame main body 51 attached to the upper end portion 31 </ b> A of the shade 31 and both ends in the longitudinal direction of the frame main body 51. The movement conversion mechanism 60 is configured to slide the slide part 52A (or 52B) with the rotational movement of the roller 61. The slide part 52A can be slid along the longitudinal direction. With such a configuration, the slide part 52A, 52B slides relative to the frame body part 51, whereby the frame 50 can be expanded and contracted.

  The motion converting mechanism 60 includes a female screw 61B provided on the roller 61 and a male screw 62B provided on the frame 50 and screwed with the female screw 61B. The male screw 62B is configured to advance and retreat along the longitudinal direction of the frame 50 through the screw 61B.

  As the roller 61 rotates, the male screw 62B screwed with the female screw 61B advances and retreats. Thereby, the rotational motion of the roller 61 can be converted into the expansion and contraction motion of the frame 50. Further, by using a screw, the frame 50 can be extended when the roller 61 is rotated forward, and the frame 50 can be contracted when the roller 61 is rotated backward.

<Embodiment 2>

Note that the same portions as those in the above embodiment are denoted by the same reference numerals and redundant description is omitted. As shown in FIG. 6, the motion conversion mechanism 160 of the present embodiment includes a shaft member 162 provided on the roller 61 and an extending portion 151 provided on the slide portion 52A. The shaft member 162 has a longitudinal shape extending outward (from the slide portion 52 </ b> A) from the roller 61, and can rotate in conjunction with the rotation of the roller 61. The extending portion 151 has a longitudinal shape extending inward (on the roller 61 side) from the slide portion 52A, and has an insertion hole 151A into which the shaft member 162 is inserted.

  A female screw 151B is formed on the inner peripheral surface of the insertion hole 151A, and a male screw 162A formed on the outer peripheral surface of the shaft member 162 is screwed into the female screw 151B. Thus, when the roller 61 rotates, the female screw 151B (slide portion side screw portion) advances and retreats via the male screw 162A (roller side screw portion). That is, the rotation motion of the roller 61 is converted into the linear motion of the extending portion 151 (and eventually the sliding motion of the slide portion 52A). Thereby, the frame 50 can be expanded and contracted in conjunction with the vertical movement of the frame 50.

<Embodiment 3>
Next, Embodiment 3 of the present invention will be described with reference to FIG.

In the sunshade device of this embodiment, the configuration of the motion conversion mechanism is different from that of the above embodiment. Note that the same portions as those in the above embodiment are denoted by the same reference numerals and redundant description is omitted. As shown in FIG. 8, the motion conversion mechanism 360 of the present embodiment includes a cylinder 362 provided on the roller 61 side, an extending portion 351 provided on the slide portion 52A, and gears 361A, 361B, 361C. I have. The cylinder 362 is connected to the roller 61 via gears 361A, 361B, and 361C, and is configured to rotate in conjunction with the rotation of the roller 61.

  A surface of the cylinder 362 on the extending portion 351 side is an inclined surface 362A that is inclined with respect to the rotation axis of the cylinder 362 (the axis along the left-right direction in FIG. 8). The extending portion 351 extends from the slide portion 52A toward the inclined surface 362A, and the tip thereof is in contact with the peripheral end portion of the inclined surface 362A. Accordingly, when the roller 61 rotates from the state of FIG. 8, the cylinder 362 rotates, so that the extending portion 351 is pressed by the inclined surface 362A, and the slide portion 52A moves away from the frame main body portion 51 as shown in FIG. It has a configuration.

  In this embodiment, an urging member (not shown) such as a coil spring is interposed between the frame main body 51 and the slide 52A, and the slide 52A is attached to the frame main body 51 side. It is energized. Accordingly, the urging member can return the state shown in FIG. 9 (the state in which the frame 50 is most extended) to the state shown in FIG. 8 (the state in which the frame 50 is most contracted).

<Embodiment 5>
Next, Embodiment 5 of the present invention will be described with reference to FIGS. In the sunshade device of this embodiment, the configuration of the motion conversion mechanism is different from that of the above embodiment. Note that the same portions as those in the above embodiment are denoted by the same reference numerals and redundant description is omitted. As shown in FIG. 10, the motion conversion mechanism 460 according to the present embodiment includes a cylinder 462 provided on the roller 61 side, an extending portion 451 provided on the slide portion 52A, and gears 361A, 361B, 361C. I have. The cylinder 462 is connected to the roller 61 via gears 361A, 361B, and 361C, and is configured to rotate in conjunction with the rotation of the roller 61.
