  However, according to the technique disclosed in Patent Document 1, the drawer member is configured to move in the drawer storage direction of the shade. Therefore, depending on the relationship between the pair of rails and the window or window frame, the gap around the shade cannot be sufficiently suppressed, or the drawer member interferes with the window or window frame. There may be cases where it is done.

  Accordingly, an object of the present invention is to allow a drawing member attached to the front end side of a shade to move in a more free direction as the pair of runners move with respect to the pair of rails.

In order to solve the above-mentioned problem, a first aspect is a sunshade for shielding a vehicle window from the vehicle interior side, and is fixed to a sheet-like shade and a base end side of the shade so as to wind the shade. A take-up device that houses the shade by a take-up shaft that is urged to rotate in the take-off direction, a draw-out member attached to the front end side of the shade, and the shade in a state in which the shade is drawn from the take-up device A pair of rails that are disposed along both side edges of each of the rails, and in which at least a part of each extending direction, the opposing distance dimension gradually decreases toward the front end side of the shade, and guides the drawer member; , a pair of runners that is movable along their extending direction in the pair of rails, rotatably mounted et the center of the first rotation axis for to an end before killer runner over Rutotomoni other end is rotatably mounted about a second rotational axis for said drawer member, a pair of said first rotary shaft and said second rotary shaft is set in a parallel positional relationship A link member, and an orthogonal plane with respect to the first rotation axis is set so as to be in a positional relationship intersecting with the pair of rails, and the pair of runners is moved to move the shade from the winding shaft. When pulled out, the pair of link members rotate relative to the runner and the pull-out member so as to adjust the lengths of the pull-out member and the pair of link members in the direction connecting the pair of runners. Thus, the drawing member is moved away from the pair of rails as the drawing member is drawn from the position where the shade is stored.

A 2nd aspect is a sunshade which concerns on a 1st aspect, Comprising: In the state by which the said shade was wound up by the said winding shaft, a pair of said 2nd rotating shaft is more than said pair of 1st rotating shaft. It is set so as to be positioned on the moving direction side when the drawing member is pulled out.

A 3rd aspect is a sunshade which concerns on a 1st or 2nd aspect, Comprising: When the said shade is pulled out from the said winding shaft, a pair of said link member rotates with respect to the said runner and the said drawing member. By doing so, the drawer member is brought into contact with the edge of the window or the passenger compartment located on the edge of the window in the direction of drawing out the shade with respect to the window.

A 4th aspect is a sunshade which concerns on a 3rd aspect, Comprising: A connection mechanism is provided between the said drawer member and each other end part of a pair of said link member, The said connection mechanism is the said drawer | drawing-out. A guide provided at the other end of the member or the link member along the extending direction thereof, movably provided in the extending direction of the guide, and the drawing member and the other end of the link member A connecting member that is rotatably connected around the second rotation shaft, and the connecting member is biased toward the end side of the drawing member or the end side of the link member along the extending direction of the guide. And an urging member.

According to the sunshade which concerns on the 1st-4th aspect, when a pair of runner moves and a shade is pulled out from a winding shaft, a pair of runner moves along with a pair of rails, and each other The interval of becomes smaller. Accordingly, since the distance between the pair of runners is shortened, the pair of link members are adjusted with respect to the runner and the drawer member so as to adjust the lengths of the drawer member and the pair of link members in the direction connecting the pair of runners. Rotate. As a result, when the stored shade is pulled out from the take-up shaft, the pull-out member moves away from the pair of rails as the pull-out member is pulled out from the position where the shade is stored. That is, the drawing member moves in a direction approaching the vehicle window or in a direction away from the vehicle window. For this reason, with the movement of the pair of runners with respect to the pair of rails, the drawing member attached to the front end side of the shade can move in a more free direction.

According to the first aspect, in at least one of the pair of link members, the first rotation shaft and the second rotation shaft are set in a parallel positional relationship, so that the pair of link members and the drawing member are on the same plane. You can move with. For this reason, a pair of link member and drawer member can move smoothly.

According to the second aspect, in a state where the shade is wound around the winding shaft, the pair of second rotating shafts is closer to the moving direction side when the pulling member is pulled out than the pair of first rotating shafts. Since the pair of runners moves to the tip side of the pair of rails and the distance between the pair of runners is shortened, the drawer member is more reliably moved in the direction of movement of the drawer member, that is, You can move in the direction you want to move.

According to the first aspect, the direction in which the drawing member moves away from the rail can be determined according to the inclination of the first rotation shaft when the sunshade is viewed from the side.

According to the third aspect, the shade and the edge of the window in the pull-out direction of the shade are brought into contact with the edge of the window in the pull-out direction of the shade or the vehicle compartment on the edge of the window. Alternatively, it is possible to effectively suppress the gap with the passenger compartment on the edge of the window. Thereby, a vehicle interior can be covered more reliably from the outside.

According to the fourth aspect, the biasing member is a kind of damper in a state in which the pulling member is in contact with the edge of the window or the casing on the edge of the window in the drawing direction of the shade. It is possible to perform error absorption of each component, sunshade assembly error absorption, or shock absorption.

{Embodiment}
Hereinafter, the sunshade according to the first embodiment will be described.

<Overall configuration>
First, the overall configuration of the sunshade will be described. 1, 3 and 5 are schematic side views showing a state in which the sunshade 20 is incorporated in the vehicle 10, and FIGS. 2, 4 and 6 are rear views of the vehicle in a state in which the sunshade 20 is incorporated in the vehicle 10. It is a schematic rear view which shows the state seen from. FIGS. 1 and 2 show a storage state in which the shade 22 is wound around the winding shaft 32, and FIGS. 3 and 4 show a state in which the shade 22 is pulled out halfway. Shows a state in which the shade 22 is pulled out so as to cover the entire window 14.

  The application target of the sunshade 20 is assumed to be a window 14 behind the vehicle 10. That is, a trapezoidal window 14 (more specifically, an isosceles trapezoidal shape whose width dimension gradually narrows upward) is provided behind the vehicle. A panel member 11 (also called a package tray) is provided below the window 14, a frame member 12 (also called a pillar) is provided on both sides of the window 14, and a ceiling 13 is provided above the window 14. Yes.

  The sunshade 20 is incorporated in the panel member 11 in the passenger compartment, and is disposed along the lower edge of the window 14. Then, the shade 22 is drawn out through the slit 11S formed in the panel member 11, whereby the window 14 is shielded by the shade 22 from the vehicle interior side.

  But the application object of this sunshade 20 is not restricted to the said example, A vehicle side window etc. may be sufficient.

  The sunshade 20 includes a shade 22, a winding device 30, a drawing member 40, a pair of rails 50, a pair of runners 60, and a pair of link members 80.

  The shade 22 is formed of a sheet-like member that is flexible enough to be wound, and is formed in a shape that can shield the target window 14 in the unfolded state. The shade 22 is formed by cutting a cloth material, a resin sheet, or the like according to the outer shape of the window 14. The shade 22 may be formed in a mesh shape. Here, the shade 22 is formed in an isosceles trapezoidal shape that matches the outer shape of the window 14. The shade 22 has two sides facing each other in a parallel state, and the lower side of the longer side of the two sides is a long side edge 22a, and is shorter of the two sides. The side on the upper bottom side is the short side edge 22b (see FIG. 6). The shade 22 has a pair of inclined edges 22c that connect both ends of the long side edge 22a and both ends of the short side edge 22b (see FIG. 6). The pair of inclined edges 22c are formed in a straight line. And it forms so that the space | interval dimension of a pair of inclination edge part 22c may become small gradually toward the short side edge part 22b from the long side edge part 22a.

  Then, the shade 22 can cover almost the entire window 14 from the inside of the window 14 in a state where the shade 22 is pulled out almost entirely from the winding device 30.

  The winding device 30 includes a winding shaft 32 that is rotatably supported around a predetermined axis. The winding shaft 32 is rotatably supported by shaft fixing brackets at both ends thereof. The shaft fixing bracket is fixed to the vehicle 10 below the slit 11S of the panel member 11. Further, the winding shaft 32 is rotationally biased in one direction of rotation (direction in which the shade 22 is wound) by a winding attachment biasing mechanism such as a coil spring.

  The long side edge 22 a of the shade 22 is fixed to the main winding shaft 32 so as not to rotate. In the following description, the longer side edge 22a side of the shade 22 may be referred to as a proximal side, and the shorter side edge 22b side may be referred to as a distal side. And the shade 22 is wound up and accommodated by the winding shaft 32 by rotating the winding shaft 32 to one side. Further, by pulling the short side edge 22b of the shade 22 from this state, the winding shaft 32 rotates in the pulling direction against the biasing force of the winding mounting biasing mechanism, and the shade 22 is pulled out. It becomes like this. In the state where the winding device 30 is attached below the panel member 11 as described above, the shade 22 is pulled out through the slit 11S.

  The drawing member 40 is formed as a rod-like member attached to the short side edge portion 22 b that is the tip side of the shade 22. Here, the length dimension of the drawing member 40 is the same as the length dimension of the short side edge portion 22b or larger (slightly larger) than the length dimension of the short side edge portion 22b. The drawing member 40 can be formed of a metal material such as a resin material or aluminum. Although it is preferable that the entire short side edge 22b of the drawing member 40 is attached to the drawing member 40, this is not essential.

  The pair of rails 50 are formed as long members made of metal or the like. The pair of rails 50 are formed in the same length dimension.

  Here, the rail 50 is formed as a long member extending linearly. But the rail 50 may be curving within the range which can support the runner 60 so that a movement is possible.

  A guide groove 51 capable of guiding the runner 60 along the extending direction is formed inside the rail 50 (see FIG. 7). The guide groove 51 is opened to face between the pair of rails 50.

  Further, the pair of rails 50 are disposed along both side edges of the shade 22 in a state where the shade 22 is pulled out from the winding device 30. Here, the shade 22 is formed in an isosceles trapezoidal shape as described above, and is disposed along the pair of inclined edges 22c. Accordingly, the pair of rails 50 are arranged such that the opposing spacing dimension gradually decreases toward the tip side of the shade 22 in the entire extending direction. Then, with a configuration in which the distance between the pair of rails 50 is gradually reduced, the drawer member 40 is moved toward the window 14 as will be described later.

  However, it is not essential that the opposing spacing dimension is gradually reduced toward the tip end side of the shade 22 in the entire extending direction of the pair of rails 50. The pair of rails may be partially curved in the extending direction, and the interval dimension may be set to be gradually reduced in at least a part of the extending direction. Even in this case, the drawing member 40 can be moved toward the window 14 at a portion where the distance between the pair of rails gradually decreases.

  The fixing of the pair of rails 50 in the above posture may be performed by fixing the base end portions of the rails 50 to both end portions of the winding device 30 or the frame members 12 on both sides of the window 14. It may be performed by fixing. The pair of rails 50 guide the drawing member 40 through the runner 60 and the like.

  The pair of runners 60 is configured to be movable along the extending direction of the pair of rails 50. Here, the runner 60 is a member formed of resin or the like, and includes a runner main body 60 a formed in a block shape that can be disposed in the guide groove 51 of the rail 50. The runner body 60a can move in a fixed posture in the guide groove 51 of the rail 50.

  A support portion 70 is provided so as to protrude between the pair of rails 50 with respect to the runner main body portion 60a. The support portion 70 is a member formed of resin, metal, or the like, and is formed as a long member that is thick enough to pass through the opening of the guide groove 51. And when the runner 60 moves the rail 50, the support part 70 moves with the said runner main-body part 60a in the state which protruded toward the pair of rail 50 through the opening of the guide groove 51. Yes.

  The pair of link members 80 are each formed into a long member by resin or metal. One end portion of the link member 80 is rotatably attached to the distal end portion of the support portion 70 of the runner 60, and the other end portion of the link member 80 is rotatably attached to the drawing member 40. Here, the other end portion of the link member 80 is attached to the end portion of the drawing member 40. But the other end part of the link member 80 does not need to be attached to the edge part of the extraction | drawer member 40, and may be attached to the position from the center.

  The pair of runners 60 and the drawing member 40 are connected by the pair of link members 80, respectively. Accordingly, when the shade 22 is pulled out or wound, the pair of runners 60 and the pullout member 40 move in the same direction in the extending direction of the pair of rails 50.

  Here, it is assumed that the shade 22 is manually pulled out or wound / stored by a driving force by a driving device (not shown) such as a motor. For example, the wire is disposed along the rail 50, and the runner 60 is connected to the wire. The runner 60 is moved along the rail 50 by winding the wire with a motor or the like and feeding it. Moves in the drawing direction and winding direction.

<Linking configuration of link members>
7A and 7B are explanatory views showing the connection configuration of the link member 80, FIG. 7A is a state in which the shade 22 is completely wound, FIG. 7B is a state in which the shade 22 is pulled out partway, FIG. 7 (c) shows a state in which the shade 22 is completely pulled out.

  As shown in FIGS. 1 to 7, a pair of link members 80 are connected to both ends of the drawing member 40, and a pair of support portions 70 are connected to the pair of link members 80. In the storage state in which the drawing member 40, the pair of link members 80, and the pair of support portions 70 are linearly arranged, the length dimension thereof is the support portion of the pair of runners 60 positioned at the base end portions of the pair of rails 50. It is set to such an extent that it can be disposed between 70.

  For this reason, in a state where the pair of runners 60 are positioned at the base end portions of the pair of rails 50, the drawing member 40 and the pair of link members 80 are linear or linear along a line connecting the pair of runners 60. Extends close.

  On the other hand, as already described, the distance between the pair of rails 50 gradually decreases toward the tip side. For this reason, when the pair of runners 60 moves to the front end side of the pair of rails 50, a spacing dimension between the pair of runners 60 that allows the drawing member 40 and the pair of link members 80 to extend linearly can be secured. Disappear. For this reason, when the pair of runners 60 moves and the shade 22 is pulled out from the take-up shaft 32, the lengths of the pull-out member 40 and the pair of link members 80 in the direction connecting the pair of runners 60 are set to a pair. The pair of link members 80 rotate with respect to the pair of runners 60 and the drawing member 40 so as to adjust according to the distance between the runners 60. That is, it is bent between each of the drawing member 40 and the pair of link members 80 and between each of the pair of link members 80 and the pair of support portions 70. Thus, the pullout member 40 moves away from the pair of rails 50 as the pullout member 40 is pulled out from the position where the shade 22 is stored. That is, the drawing member 40 moves in a direction away from the line connecting the pair of runners 60.

  Here, one end portions of the pair of link members 80 are attached to the pair of support portions 70 via the pin-shaped members 88 so as to be rotatable about the pair of first rotation axes X1. Each other end of the link member 80 is attached to the drawing member 40 via another pin-shaped member 88 so as to be rotatable about the pair of second rotation axes X2. For this reason, the pair of link members 80 rotate in a plane orthogonal to the first rotation axis X1, and the drawing member 40 rotates in a plane orthogonal to the second rotation axis X2.

  Here, the pair of first rotation axes X1 and the pair of second rotation axes X2 are set in parallel. Thereby, the pair of link members 80 and the drawing member 40 can move smoothly on a plane orthogonal to both the first rotation axis X1 and the second rotation axis X2. However, there may be a mode in which the drawing member is curved. In such a case, it is not necessary for the pair of first rotation axes X1 to be parallel to each other and the pair of second rotation axes X2 to be parallel to each other in the relationship between both ends of the drawing member 40. In at least one of the pair of link members (preferably in each of both), it is preferable that the first rotation axis and the second rotation axis are parallel.

  Further, when the pair of runners 60 moves to the front end side of the pair of rails 50, the direction in which the drawing member 40 moves is determined by the directions of the first rotation axis X1 and the second rotation axis X2.

  Here, the drawing member 40 can move away from the first rotation axis X1 so that the drawing member 40 can move away in a direction intersecting the movement locus of the line connecting the pair of runners 60 (that is, a direction approaching or leaving the window 14). The orthogonal plane is set so as to be in a positional relationship that intersects obliquely with respect to the movement trajectory of the line connecting the pair of runners 60. Here, the pair of rails 50 are formed in a straight line, and the runner 60 moves in a straight line. For this reason, the movement trajectory of the line connecting the pair of runners 60 draws a plane between the pair of runners 60. When the first rotation axis X1 and the second rotation axis X2 are orthogonal to the plane, the drawing member 40 moves along the plane. Therefore, here, the first rotation axis X1 and the second rotation axis X2 are set so as to intersect with the plane in a non-orthogonal state. Thereby, the extraction | drawer member 40 can move away in the direction which cross | intersects with respect to the movement locus | trajectory of the line which connects a pair of runner 60. FIG. The moving direction of the drawing member 40 at this time is on the opposite side of the first rotation axis X1 with respect to the second rotation axis X2.

  More specifically, the first rotation axis X1 and the second rotation axis X2 are arranged on the window 14 side in the state where the sunshade 20 is viewed from the side (the state viewed from one side in the direction connecting the pair of rails 50). It is set so as to be inclined toward the base end side of the pair of rails 50, that is, the lower end side of the window 14 with respect to the direction orthogonal to the movement locus (see FIG. 3). For this reason, the pair of link members 80 and the drawing member 40 are a pair of rails 50 in a direction orthogonal to the first rotation axis X1 and the second rotation axis X2, that is, in a direction orthogonal to the movement locus on the window 14 side. It is possible to move along the direction of tilting toward the tip side.

  Here, the 1st rotation axis X1 and the 2nd rotation axis X2 are set so that the horizontal direction orthogonal to the perpendicular direction which is a gravity direction may be followed. Accordingly, the pair of link members 80 and the drawing member 40 can move in a direction orthogonal to the first rotation axis X1 and the second rotation axis X2, that is, a vertical direction that is the direction of gravity.

  As described above, the pair of link members 80 causes the shade 22 to wind the winding shaft 32 on the winding shaft 32 with a force that moves so as to change the distance between the pair of runners 60 along the pair of rails 50. The drawing member 40 is converted to a force that moves the drawing member 40 away in a direction intersecting the movement locus in a state where the drawing member 32 is drawn out from the taken-up shaft 32.

  In the above example, the drawing member 40 can move to the side approaching the window 14 and the side moving away from the window 14. Whether the drawer member 40 (that is, the tip end portion of the shade 22) should be close to the window 14 side or should be kept away from the window 14 in the state where the shade 22 is pulled out is determined. It is determined by the arrangement of the components of the vehicle 10 near the section.

  Here, the edge of the ceiling 13 of the vehicle 10 is provided in the direction in which the shade 22 is pulled out with respect to the window 14. The ceiling 13 itself protrudes further toward the passenger compartment side than the window 14, but the tip of the rail 50 is positioned before reaching the ceiling 13. Therefore, a gap is formed between the line connecting the pair of runners 60 and the window 14 in a state where the runner 60 reaches the tip of the rail 50. Therefore, here, the drawer member 40 (that is, the front end portion of the shade 22) is moved toward the edge of the window 14 in a state where the shade 22 is completely drawn out.

  More specifically, in a state where the shade 22 is wound on the winding shaft 32, the second rotation axis X2 is maintained in a state of being positioned closer to the front end side of the rail 50 than the first rotation axis X1. ing. In this state, the position restriction for preventing the runner 60 from facing further to the base end side of the rail 50 is, for example, that the runner 60 comes into contact with a stopper 52 provided on the rail 50 (FIG. 7A). (See Fig.), Or the drawing member 40 is brought into contact with the peripheral edge of the slit 11S of the panel member 11 or the like. Thereby, in all the states including the state where the shade 22 is wound around the winding shaft 32, the drawing member 40 is in a state of being positioned closer to the distal end side of the rail 50 and the window 14 side than the line connecting the pair of runners 60. Is maintained. Therefore, when the pair of runners 60 moves from the above state to the distal end side of the pair of rails 50, the link member 80 and the drawing member 40 are paired in a plane orthogonal to the first rotation axis X1 and the second rotation axis X2. It moves in the direction toward the front end side of the rail 50 and the window 14 side.

  As a result, the shade 22 is wound around the winding shaft 32 so that the pair of link members 80 moves such that the distance between the pair of runners 60 moves along the pair of rails 50. It is possible to convert the drawing member 40 into a force that moves the drawing member 40 closer to the window 14 in a state where the drawing member 32 is drawn from the winding shaft 32.

  In the above-described embodiment, the shade 22 is wound around the winding shaft 32, and the second rotation axis X2 is positioned closer to the distal end side of the rail 50 than the first rotation axis X1 with respect to the drawing member 40. Although the link member 80 is in an inclined state, it is not always necessary to have such an arrangement.

  For example, as in the modification shown in FIG. 9, a long member having a certain width may be used as the link member 180 corresponding to the link member 80. When the position of the first rotation axis X1 and the position of the second rotation axis X2 in the link member 180 are shifted in the width direction of the link member 180, the link member 180 extends linearly with respect to the drawing member 40. Thus, the second rotation axis X2 can be set so as to be positioned closer to the distal end side of the rail 50 than the first rotation axis X1 (movement direction side when the extraction member 40 is pulled out).

<Specific connection structure example of link member>
A specific connection structure example of the link member 80 will be described.

  In the example shown in FIGS. 10 and 11, the link member 280 corresponding to the link member 80 is formed in an elongated shape, and a regulation convex portion 282 is formed at the intermediate portion in the extending direction, and both end portions thereof. The connection end portion 284 is formed in the configuration.

  The pair of connecting end portions 284 are formed in a flat shape in the same direction, and an insertion hole 284h is formed in each central portion. When viewed along the axial direction of the insertion hole 284h, the outer corner portions of the pair of connecting end portions 284 are rounded.

  The restricting convex portion 282 is formed in a rectangular parallelepiped shape that protrudes to one main surface side (one side in the axial direction of the insertion hole 284 h) of the pair of connecting end portions 284. Each surface of the restricting convex portion 282 facing the pair of connecting end portions 284 forms a surface orthogonal to the extending direction of the link member 280.

  Further, an insertion hole 240 h is formed at the end of the drawing member 240 corresponding to the drawing member 40. When viewed along the axial direction of the insertion hole 240h, one corner 240a (the corner opposite to the window 14) of the two outer corners of the drawing member 240 is rounded, and the other The corner 240b (the corner on the window 14 side) has a right-angled shape.

  An insertion hole 270 h is formed in the support portion 270 corresponding to the support portion 70. When viewed along the axial direction of the insertion hole 270h, one corner 270a (corner on the window 14 side) of the two corners 270a, 270b outside the support portion 270 is rounded, and the other The corner portion 270b (the corner portion on the opposite side of the window 14) has a right-angled shape.

  Then, the pin member 290 is inserted through the one insertion hole 284h of the link member 280 and the insertion hole 270h of the support portion 270, and the tip end portion of the pin member 290 is crushed or the like as necessary to prevent it from being removed. Further, the other pin member 290 is inserted into the other insertion hole 284h of the link member 280 and the insertion hole 240h of the extraction member 240, and the tip end portion of the pin member 290 is crushed or the like to prevent it from being removed. Accordingly, the link member 280 is rotatably connected to the support portion 270, and the drawing member 240 is rotatably connected to the link member 280. This is performed at both ends of the drawing member 240.

  In this example, since one corner 270a of the two outer corners of the support portion 270 is rounded, when the link member 280 rotates toward the window 14 with respect to the support portion 270, Interference between the corner portion 270a and the restricting convex portion 282 is suppressed. On the other hand, since the other corner portion 270b of the support portion 270 maintains a right-angled shape, when the link member 280 tries to rotate to the opposite side of the window 14 with respect to the support portion 270, the corner portion 270b becomes the restriction convex portion 282. Interfere with.

  Similarly, since one corner 240a of the two outer corners of the drawing member 240 is rounded, when the link member 280 tries to rotate toward the window 14, the corner 240a and the regulating protrusion Interference with the part 282 is suppressed. On the other hand, since the other corner portion 240b of the pull-out member 240 has a right-angled shape, the corner portion 240a interferes with the restricting convex portion 282 when the link member 280 attempts to rotate to the side opposite to the window 14. .

  For this reason, the link member 280 and the drawer member 240 can be moved to the window 14 side more reliably.

  In the example shown in FIGS. 12 and 13, the link member 380 corresponding to the link member 80 is formed in a long plate shape, and the connection end portions 384 are formed at both ends thereof.

  The pair of connecting end portions 384 are formed in a flat shape, and an insertion hole 384h is formed in each central portion. When viewed along the axial direction of the insertion hole 384h, the outer corner portions of the pair of connecting end portions 384 are rounded.

  Further, the end portion of the drawing member 340 corresponding to the drawing member 40 includes a bottom portion 341 and a pair of side wall portions 342 rising from both side portions of the bottom portion 341. The end of the drawing member 340 is open on the opposite side of the bottom 341 (the opposite side of the window 14). In addition, an insertion hole 342h is formed coaxially at the ends of the pair of side wall portions 342.

  The support portion 370 corresponding to the support portion 70 includes a bottom portion 371 and a pair of side wall portions 372 rising from both side portions of the bottom portion 371, and an end portion of the support portion 370 is opposite to the bottom portion 371 (window 14. The side is open. The pair of side wall portions 372 are formed with insertion holes 372h coaxially.

  Then, in a state where one end portion of the link member 380 is disposed between the pair of side wall portions 372 of the support portion 370, the pin member 390 is inserted into the insertion hole 372h of the pair of side wall portions 372 and one insertion hole of the link member 380. The tip of the pin member 390 is crushed to prevent it from being inserted through 384h. Further, with the other end of the link member 380 disposed between the pair of side wall portions 342 of the drawing member 340, the other pin member 390 is inserted into the insertion hole 342h of the pair of side wall portions 342 and the other of the link member 380. Is inserted into the insertion hole 384h, and the tip end portion of the pin member 390 is crushed or the like to prevent it from being removed as necessary. Accordingly, the link member 380 is rotatably connected to the support portion 370, and the drawing member 340 is rotatably connected to the link member 380. This is done at both ends of the drawer member 340.

  In this example, one end of the pair of side wall portions 372 is closed by the bottom portion 371 and the other side is open among the end portions of the support portion 370. For this reason, when the link member 380 is about to rotate toward the window 14 with respect to the support portion 370, the link member 380 can rotate through the opening on the other side of the end portion of the support portion 370. At this time, since the outer corner portion of the connecting end portion 384 of the link member 380 is rounded, interference between the outer corner portion and the bottom portion 371 is suppressed. On the other hand, when the link member 380 tries to rotate to the opposite side of the window 14 with respect to the support portion 370, the link member 380 hits the bottom portion 371. For this reason, the rotation of the link member 380 to the opposite side of the window 14 with respect to the support portion 370 is suppressed.

  Similarly, one end of the pair of side wall portions 342 is closed by the bottom portion 341 among the end portions of the drawing member 340, and the other side is open. For this reason, when the link member 380 is about to rotate toward the window 14, the link member 380 can rotate through the opening on the other side of the end of the drawing member 340. On the other hand, when the link member 380 tries to rotate to the side opposite to the window 14, the link member 380 comes into contact with the bottom portion 341 of the drawing member 340, and the rotation in the direction is suppressed.

  For this reason, the link member 380 and the drawer member 340 can be moved to the window 14 side more reliably.

<Operation>
The operation of the sunshade 20 will be described.

  First, in the housed state, it is assumed that the shade 22 is wound around the winding shaft 32 and the pair of runners 60 are located at the base end portions of the pair of rails 50. In this state, the movement of the pair of runners 60 toward the base end side of the pair of runners 60 is restricted, and the second rotation axis X2 is positioned closer to the distal end side of the rail 50 than the first rotation axis X1 ( FIG. 1, FIG. 2 and FIG. 7 (a)). In this state, preferably, the drawing member 40 is disposed in a position covering the slit 11S of the panel member 11 or in the slit 11S.

  From this state, the user operates the drive device to pull out the shade 22 through the operation unit or the like. Then, the pair of runners 60 moves toward the distal ends of the pair of rails 50. Thereby, a pair of runner 60 moves to a mutual approach direction. Then, the pair of link members 80 rotate so as to move toward the window 14 around the first rotation axis X1, and the drawing member 40 rotates around the second rotation axis X2. Thereby, the drawing member 40 moves to the window 14 side and the distal end side of the pair of rails 50 with respect to the line connecting the pair of runners 60 (see FIGS. 3, 4, 7B, and 8). .

  When the shade 22 is completely pulled out, the pulling member 40 moves more greatly toward the window 14 side and the tip end side of the pair of rails 50 with respect to the line connecting the pair of runners 60 (FIGS. 5, 6, and 7). (See (c)). In a state where the pair of runners 60 has moved to the distal ends of the pair of rails 50, the operation of the driving device is stopped and the wires connected to the runners 60 are locked, or the pair of runners 60 and the pair of rails 50 It is good to be held by the frictional force.

  In this state, preferably, the drawer member 40 faces the edge of the ceiling 13 on the upper and outer sides of the window 14 until it contacts the ceiling 13 or is disposed at a position overlapping the ceiling 13 as viewed from the driver. Then, it moves to the tip side of the pair of rails 50 on the window 14 side. Thereby, the leading end portion of the drawer member 40 and the shade 22 drawn by the drawing member 40 is disposed between the line connecting the pair of runners 60 and the upper edge portion of the window 14 or the edge portion of the ceiling 13. The gap between the shade 22 and the peripheral portion of the window 14 in the vehicle 10 can be effectively suppressed. This makes it possible to more reliably cover the vehicle interior from the outside.

  When the drawer member 40 is moved to the base end side of the pair of rails 50 from the state in which the shade 22 is pulled out as described above, the reverse operation is performed, and the drawer member 40 is directed toward a line connecting the pair of runners 60. Move. Thereby, the drawer member 40 can be disposed along or near the line connecting the rails 50 and can be easily accommodated in the panel member 11, for example.

<Effects>
According to the sunshade 20 configured as described above, each one end portion is rotatably attached to the support portion 70 of the pair of runners 60, and each other end portion is rotatably attached to the drawing member 40. A pair of link members 80 are provided. Then, in a state where the shade 22 is pulled out more, the pair of link members 80 moves the pair of runners 60 so as to move the pair of runners 60 along the pair of rails 50 so that the distance between the pair of link members 80 varies. The drawing member 40 is converted into a force that moves the drawing member 40 away in a direction that intersects the movement locus of the line connecting the pair of runners 60. For this reason, when the drawing member 40 is pulled out from the winding shaft 32, the drawing member 40 intersects the movement trajectory of the line connecting the pair of runners 60, that is, the direction approaching the window 14 or the direction moving away from the window. Move to. For this reason, with the movement of the pair of runners 60 with respect to the pair of rails 50, the drawing member 40 attached to the front end side of the shade 22 can be moved in a more free direction. Thereby, it becomes possible to set the moving direction of the drawing member 40 relatively freely according to the layout of the peripheral members of the window 14, and to suppress the gap between the shade 22 and the peripheral members as much as possible. It becomes.

  Moreover, since the drawer member 40 is moved using the movement in a direction in which the pair of runners 60 approaches or vice versa, the configuration for moving the drawer member 40 is provided. It can be made compact in the moving direction.

  Further, in the configuration in which a plate-like portion is provided on the drawing member and the posture of the plate-like portion is changed to close the gap around the shade, the drawing member has a large configuration. Here, since the position of the drawing member 40 itself is changed to devise the drawing position and direction of the shade 22 to suppress the gap around the shade 22, the drawing member 40 can be made compact.

  In addition, since the pair of first rotation axes X1 and the pair of second rotation axes X2 are set in parallel, the pair of link members 80 and the drawing member 40 can move on the same plane. For this reason, a pair of link member 80 and drawer member 40 can move smoothly.

  Further, the winding device 30 pulls the shade 22 in the winding direction by urging the winding shaft 32 to rotate. For this reason, the winding force acts in a well-balanced manner in the entire extending direction of the drawing member 40, and the winding shaft 32 and the drawing member 40 can be kept in a parallel state. In this state, as the pair of runners 60 moves, the link member 80 operates on both end sides of the pull-out member 40. Therefore, the pair of first rotation axes X1 and the pair of second rotations on both end sides of the pull-out member 40. The rotation operation of the pair of link members 80 around the axis X2 can be performed with a good balance. Thereby, the drawer | drawing-out member 40 can be moved with sufficient balance on both ends. The structural portion including the link member 80 on one end side of the drawing member 40 and the structural portion including the link member 80 on the other end side of the drawing member 40 pass through the center in the extending direction of the drawing member 40 and the drawing member 40. It is preferable to have mirror symmetry with respect to a plane orthogonal to the reference. If it has mirror symmetry, the link member 80 and the drawing member 40 can move on the same plane even if the drawing member 40 is curved along the upper edge of the window 14. In this case, in each link member 80, the first rotation axis X1 and the second rotation axis X2 are set in parallel, and the second rotation axis X2 is set orthogonal to the curvature of the drawing member 40.

  In addition, in a state where the shade 22 is wound on the winding shaft 32, the pair of second rotation axes X2 are located on the front end side of the pair of rails 50 with respect to the pair of first rotation axes X1. For this reason, if a pair of runner 60 moves to the front end side of a pair of rail 50 from this state, and the distance between a pair of runner 60 becomes short, the drawer member 40 will move to the front end side of a pair of rail 50 more reliably. be able to.

  Further, in the present embodiment, when the pair of runners 60 moves along the pair of rails 50 toward the distal end side thereof, and the distance between them decreases, the drawing member 40 moves toward the side closer to the window 14. For this reason, it is possible to effectively suppress the gap between the shade 22 and the window 14.

{Modification}
Various modifications will be described based on the above embodiment.

<Modifications related to drawer member>
FIG. 14 is an explanatory view showing a modified example related to the drawing member 40. FIG. 14 shows a state where the shade 22 is completely pulled out.

  In this example, the drawer member 440 includes a drawer body member 442 and a pair of end extension members 444. The drawer body member 442 has the same configuration as that of the drawer member 40, and a link member 80 is rotatably connected to an end portion thereof. The pair of end extension members 444 are members attached to both ends of the drawer body member 442 so as to extend outward from both ends of the drawer body member 442. In the drawer member 440, the end extension members 444 are attached to both ends of the drawer body member 442, whereby a long member is formed, and the end side edge portion of the shade 22 is attached to the entire longitudinal direction thereof. It has been. In other words, the extending direction intermediate portion of the front end side edge portion of the shade 22 is attached to the drawer body member 442, and both end portions of the front end side edge portion of the shade 22 are attached to the pair of end portion extension members 444. It has been.

  As shown in this modification, it is not essential that the link member 80 is attached to the end portion of the drawing member 440.

<Modification with a torsion coil spring>
FIG. 15 shows a modified example in which a torsion coil spring 590 is provided as a biasing member for rotating the link member 80 in a direction away from the movement locus at a connecting portion between the support portion 70 and the link member 80. FIG. 15 shows a state where the shade 22 is completely pulled out.

  The torsion coil spring 590 has a configuration in which a linear spring material is bent into a ring shape, and end portions 593 of the spring material are extended outward from the two portions of the ring-shaped portion 592 along respective tangential directions. ing. The ring-shaped portion 592 of the torsion coil spring 590 is disposed around the first rotation axis X1 between the support portion 70 and the link member 80, one end portion 593 is disposed along the support portion 70, and the other The end portion 593 is disposed along the link member 80. Then, due to the torsional moment of the pair of end portions 593 around the first rotation axis X1, the link member 80 rotates around the first rotation axis X1 toward the window 14 and the front end side of the rail 50. It is energized as follows.

  According to this modification, when the shade 22 is wound up and the pair of runners 60 are positioned on the base end sides of the pair of rails 50, the shade 22 is pulled out and the pair of runners 60 approaches the torsion coil spring 590. Due to the urging force, the link member 80 rotates with respect to the support portion 70 around the first rotation axis X <b> 1 toward the window 14 side and the front end side of the rail 50. For this reason, there exists an advantage that the link member 80 and the drawer member 40 can be rotated more reliably in a desired direction.

  When this configuration is adopted, the pair of second rotating shafts X2 is positioned closer to the distal ends of the pair of rails 50 than the pair of first rotating shafts X1 in a state where the shade 22 is wound on the winding shaft 32. It does not have to be.

  A torsion coil spring may be provided between the link member 80 and the drawing member 40 so as to urge the drawing member 40 in a direction away from a line connecting the pair of runners 60.

  That is, when at least one of the pair of first rotating shafts X1 and the pair of second rotating shafts X2 is provided with a biasing member that biases the drawing member 40 away from a line connecting the pair of runners 60. It becomes possible to move the drawing member 40 in a desired direction more reliably.

<Modification for enabling displacement of second rotation axis X2>
FIG. 16 is an explanatory diagram showing a modification for enabling displacement of the second rotation axis X2. 16A shows a state in which the shade 22 is completely wound up, FIG. 16B shows a state in which the shade 22 is pulled out halfway, and FIG. 16C shows a state in which the shade 22 is completely pulled out. ing. FIG. 17 shows a state in which the drawing member 40 is in contact with the edge of the ceiling 13 in this modification.

  In this modification, a coupling mechanism is provided between both end portions of the drawing member 640 corresponding to the drawing member 40 and the other end portions of the pair of runners 60. This connection mechanism includes an insertion hole 640h as a guide, a pin-shaped portion 682 as a connection member, and a coil spring 690 as an urging member.

  More specifically, a long hole-like insertion hole 640h is formed at both ends of the drawing member 640 along the extending direction. A pin-like portion 682 protruding from the other end of the link member 680 corresponding to the link member 80 is inserted into the insertion hole 640h. The tip of the pin-shaped portion 682 is crushed as necessary, and is prevented from being removed from the insertion hole 640h. And the pin-shaped part 682 is connected with the drawer member 640 in the state which can move along the extension direction of the drawer member 640. As shown in FIG. That is, the second rotation axis X2 can be displaced within a certain range in the extending direction of the drawing member 640.

  In addition, a coil spring 690 that urges the pin-shaped portion 682 outward (each end side of the pull-out member 40) is incorporated in a connection portion between the pull-out member 640 and the pin-shaped portion 682. Here, in a state where the coil spring 690 is compressed, one end thereof is connected to a portion of the insertion hole 640 h from the center of the drawing member 640, and the other end is connected to the pin-shaped portion 682.

  For this reason, in a state where a large external force is not applied to the pull-out member 640, the second rotation axis X2 remains in the outer portion of the pull-out member 640 in the insertion hole 640h, and the pair of runners 60 moves. Similarly to the above embodiment, the drawing member 640 moves in a direction away from the line connecting the pair of runners 60 or a direction approaching the line.

  Then, when the pair of runners 60 is moved toward the distal ends of the pair of rails 50, the drawer member 640 contacts the edge of the ceiling 13 at the top of the window 14 (on the extension of the shade 22 in the drawer direction). As shown in FIG. 17, the pin-shaped portion 682 (second rotation axis X <b> 2) moves toward the position from the center of the drawing member 640 as shown in FIG. 17. As a result, the pair of runners 60 can be further moved to the distal ends of the pair of rails 50 while the drawing member 640 is in contact with the edge of the ceiling 13. The drawer member may be brought into contact with the edge of the window.

  According to this modification, for example, in the configuration in which the shade 22 is opened and closed by moving the pair of runners 60, the position where the pair of runners 60 reaches and the position where the drawer member 640 hits the edge of the ceiling 13 are shifted. Even in such a case, the drawer member 640 can be more reliably applied to the edge of the ceiling 13. As a result, the coil spring 690 as a biasing member operates as a kind of damper, and absorbs errors, assembly errors, assembly errors of the sunshade 20 with respect to the vehicle, and a more reliable shade. The gap between 22 and its peripheral members can be suppressed. Further, it is possible to absorb the impact when the drawing member 40 comes into contact with the edge of the ceiling 13.

  A long hole-like insertion hole is formed on the link member side, a pin-like portion on the drawer member side is movably inserted into the insertion hole, and the pin-like portion is connected to the end of the link member by a biasing member such as a coil spring. It may be biased to the part side. In addition, a long hole-like insertion hole is formed on one side of the link member and the support portion of the runner portion, and a pin-like portion provided on the other side is movably inserted into the insertion hole, and the pin-like portion is a coil spring. It may be urged toward the outside of either one of the link member and the support portion of the runner portion by an urging member such as. Even in these cases, in the same manner as described above, when the extraction member hits the movement destination member, the first rotation axis X1 or the second rotation axis X2 is displaced to absorb the assembly error and the like. In addition, the gap between the shade and its peripheral members can be suppressed.

<Modified example for adjusting the direction of the rotation axis>
If the fixed posture of the sunshade 20 with respect to the vehicle is different, there is a possibility that a gap is generated between the drawing member 40 and the ceiling 13. Therefore, in this modification, an example will be described in which the directions of the first rotation axis X1 and the second rotation axis X2 can be adjusted.

  FIG. 18 and FIG. 19 are explanatory diagrams illustrating modifications for enabling adjustment of the directions of the first rotation axis X1 and the second rotation axis X2. In FIG. 20, this modified example is depicted in a simplified manner. 20A shows a state in which the shade 22 is completely wound, FIG. 20B shows a state in which the shade 22 is pulled out halfway, and FIG. 20C shows a state in which the shade 22 is completely pulled out. ing.

  With respect to this modified example, first, with reference to FIGS. 18 and 19, the difference from the modified example shown in FIGS. 12 and 13 will be mainly described.

  That is, in this modified example, the runner 760 corresponding to the runner 60 is formed with a protrusion 761 protruding from the inner opening of the rail 50, and the support hole 762 along the line connecting the pair of runners 760 to the protrusion 761. Is formed (see FIG. 20A). The support hole 762 opens toward the pair of runners 760.

  The support portion 770 corresponding to the support portion 70 includes a shaft portion 772 that can be rotatably fitted in the support hole portion 762, and a connecting portion 774 that can link the link member 80 in a rotatable manner. The connecting portion 774 has the same configuration as the supporting portion 370 of the modification shown in FIGS.

  A screw hole 762h is formed in a portion of the runner 760 around the support hole 762, and the screw S can be screwed into the screw hole 762h.

  Then, the support portion 770 can be rotated around the central axis of the shaft portion 772 in a state where the shaft portion 772 is fitted into the support hole portion 762. By rotating the support portion 770, the direction of the first rotation axis X1, which is the central axis of the insertion hole 372h formed in the connecting portion 774, can be changed (see the arrow in FIG. 19). At the same time, the direction of the second rotation axis X2 parallel to the first rotation axis X1 can also be changed. Then, with the direction of the first rotation axis X1 and the second rotation axis X2 adjusted to appropriate positions, the screw S is tightened so that the tip of the screw S contacts the shaft portion 772 in the support hole 762. Touch. Accordingly, the support portion 770 is fixed in a fixed posture in the runner 760, and the directions of the first rotation axis X1 and the second rotation axis X2 are kept constant.

  Accordingly, the directions of the first rotation axis X1 and the second rotation axis X2 are adjusted so as to eliminate the gap around the shade as much as possible according to the assembly error of the sunshade 20 or the vehicle type difference. be able to.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
