  Hereinafter, the shade device 10 according to the embodiment will be described (see FIGS. 1 and 2). The shade device 10 is a device that shields the window 1 with the main shade 20 and the subshade 60. That is, the shade device 10 is configured to shield the portion of the window 1 that cannot be shielded by the main shade 20 with the sub shade 60.

<Window>
For convenience of explanation, the window 1 to which the shade device 10 is applied will be described. The window 1 is a deformed window such as a trapezoid, and has a shape having a deformed portion on the side with respect to a rectangle. Here, an example in which the shade device 10 is applied to a window 1 as a rear window of an automobile will be described. More specifically, the window 1 has a substantially trapezoidal shape (here, a substantially isosceles trapezoidal shape) having a narrow width from the floor side to the ceiling side of the vehicle body and having a short side on the ceiling side and a long side on the floor side. Is formed. That is, right triangular portions are provided on both sides of the central rectangular portion. The window frame surrounding the window 1 includes a ceiling side horizontal frame 1A, a floor side horizontal frame 1B, and a side vertical frame 1C.

<Shade device>
Depending on the window 1, it may be difficult to use a shade that can be shielded over the entire length of the long side or to dispose the shade device on the long side due to the surrounding space. Therefore, the shade device 10 is configured to shield the portion that cannot be shielded by the main shade 20 by using the secondary shade 60.

  Here, the present shade device 10 is disposed around the window 1 so that the main shade 20 is pulled out from the ceiling side horizontal frame 1A side toward the floor side horizontal frame 1B side. The direction connecting the ceiling side horizontal frame 1A and the floor side horizontal frame 1B is referred to as a drawer storage direction P.

  The shade device 10 includes a main shade 20, a winding device 30, a drawing member 40, a pair of guide rails, a subshade 60, an interlocking mechanism portion 70, and a drive mechanism portion 90.

  The main shade 20 is a member mainly shielding the window 1 (see FIG. 2). The main shade 20 is formed in a size and shape capable of partially shielding the window 1 by cutting, sewing, etc., a mesh-like cloth material, a resin sheet or the like. Here, the main shade 20 is formed in a size and a rectangular shape capable of shielding a central portion in the width direction of the window 1, that is, a rectangular portion having a short side on the side of the ceiling side horizontal frame 1A as one side. And the main shade 20 can shield the window 1 entirely with the subshade 60 mentioned later. Hereinafter, a portion of the window 1 that is shielded by the main shade 20 may be referred to as a main shielding portion, and a side portion thereof may be referred to as a sub shielding portion. The sub-shielding portion is a substantially right-angled triangular portion having the side vertical frame 1C of the window 1 as a hypotenuse.

  But the main shade 20 should just be formed corresponding to the shape of the window 1 as mentioned above, and may be formed in the trapezoid etc. which can shield a part of window 1 other than rectangular shape. .

  The main shade 20 is attached to a winding device 30 (see FIG. 3). The winding device 30 includes a base 32, a winding shaft portion 34, and a pair of rotation support portions 36. And the winding device 30 is comprised so that the main shade 20 may be drawn out along the drawer | accommodating storage direction P, and winding up so that accommodation is possible.

  The base 32 is a member formed by cutting, bending or the like of a metal plate, or a member formed by extruding a metal. Further, the base 32 may be formed of a synthetic resin. The base 32 is fixed to a vehicle body panel or the like by screwing or the like. A pair of rotation support portions 36 are erected on the base 32.

  The winding shaft portion 34 is a long cylindrical member, and is supported by a pair of rotation support portions 36 so as to be rotatable around the central axis. A base end edge portion (storage side end edge portion) of the main shade 20 is attached to the outer peripheral surface of the winding shaft portion 34 along the axial direction thereof.

  The take-up shaft 34 is urged to rotate in a direction to take up the main shade 20 by an urging member such as a coil spring (not shown) with respect to the rotation support 36. That is, the main shade 20 is wound around the winding shaft portion 34 by the winding force in a state where the pulling force larger than the winding force by the urging member does not act, and when the pulling force larger than the winding force is applied, the main shade 20 is wound. It is pulled out from the handle portion 34.

  Here, the winding device 30 is disposed inside the ceiling-side horizontal frame 1A. More specifically, the base 32 is fixed to the vehicle body panel or the like inside the ceiling side horizontal frame 1 </ b> A in a posture in which the winding shaft portion 34 is orthogonal to the drawer housing direction P. It is assumed that a slit for pulling out the main shade 20 is formed along the short side of the window 1 in the ceiling side horizontal frame 1A.

  A drawing member 40 is attached to the leading edge (drawing side edge) of the main shade 20. The drawing member 40 includes a stay 42 and a pair of runners 44 (see FIG. 2). The stay 42 is a long bar-like portion attached along the tip of the main shade 20. The pair of runners 44 are connected to both ends of the stay 42 and are portions guided by a pair of guide rails described later. In addition, the pair of runners 44 has an interlocking protrusion 46 for pushing and moving an advance / retreat link 72 of the interlocking mechanism 70 described later.

  The main shade 20 can be pulled out and stored by moving the drawer member 40 along the drawer storage direction P. The state in which the main shade 20 is wound up and retracted into the ceiling-side horizontal frame 1A is referred to as a stored state, and the state in which the main shade 20 is pulled out and the main shielding portion of the window 1 is shielded is referred to as a drawn-out state.

  The pair of guide rails are portions that guide the drawer member 40 along the drawer housing direction P. The pair of guide rails are long members that can be guided so that the pair of runners 44 move along one direction (longitudinal direction), respectively (see FIGS. 4 and 5). Here, both of the pair of guide rails are movable rails 50 to which subshades 60 described later are coupled.

  The movable rail 50 is formed in a shape that can be concavo-convexly fitted so that it cannot move relative to the runner 44 in a direction orthogonal to the longitudinal direction (a slight play may be set). More specifically, the movable rail 50 has a plurality of guide protrusions 52 that are bent (bent along two orthogonal directions) in a cross-sectional view orthogonal to the longitudinal direction, and protrude from the plate-shaped main body portion. It is provided in the form to do. On the other hand, the runner 44 has a groove 48 that can be contacted from both sides in two directions orthogonal to the plurality of guide protrusions 52 of the movable rail 50. Further, the movable rail 50 has a rack groove portion 54 into which a flexible rack member 92 of a drive mechanism portion 90 described later can be inserted.

  The movable rail 50 may be formed by cutting, bending, or the like of a metal plate or by extruding molten metal. The movable rail 50 may be formed by extruding synthetic resin.

  The movable rail 50 is provided so as to be movable between a retracted position and an advanced position. The retracted position is a position where the auxiliary shade 60 is retracted to the side of the window 1 (here, in the side vertical frame 1C) (see FIGS. 1 and 6). Further, the advanced position is a position where the attached secondary shade 60 can guide the runner 44 along the pull-out storage direction and shields the secondary shielding portion of the window 1 (see FIGS. 2 and 8). The side vertical frame 1C is formed with a slit through which the movable rail 50, the subshade 60, and the like can enter and exit, and the movable rail 50 is moved between the advanced position and the retracted position through the slit.

  Here, the auxiliary shade 60 will be described. As described above, when the winding device 30 is disposed in the ceiling side horizontal frame 1A on the short side of the window 1, the winding device 30 wider than the short side is disposed in space. Can be difficult. Since the shade device 10 employs the main shade 20 corresponding to the short side of the window 1 (the width dimension is substantially the same), a portion where the window 1 cannot be shielded on the side of the main shade 20 occurs. Therefore, the shade device 10 is configured to shield the side of the main shade 20 with the auxiliary shade 60 for one window 1 to be shielded (see FIG. 2).

  The sub-shade 60 is formed in a size and shape that can shield a side portion (sub-shielding portion) of the portion of the window 1 that is shielded by the main shade 20. Thereby, the sub shade 60 shields the window 1 as a whole together with the main shade 20. As the subshade 60, a cloth or a resin sheet having a light shielding property (may be slightly translucent like a mesh) or a sheet formed by cutting or sewing can be employed. . Here, it is assumed that the auxiliary shade 60 is formed in a sheet shape. Of the sub-shade 20, an end edge portion on the opposite side to the main shade 20 is preferably fixed to a vehicle body panel or the like of the vehicle.

  Further, here, the auxiliary shade 60 shields the auxiliary shielding portion together with a part of the movable rail 50. More specifically, the movable rail 50 has a side panel 56 having a surface along the main shade 20 that is drawn out in the longitudinal direction to the vehicle interior side of the main body portion. The sub-shade 60 is attached to the edge of the side panel 56 on the side opposite to the main shade 20.

  In addition, an end edge portion on the main shade 20 side of the side panel 56 that shields the sub shielding portion together with the sub shade 60 is formed in a shape (here, a straight line shape) along the shape of the side of the main shade 20. It is good to be. The sub-shade 60 and the side panel 56 are configured so that the edge of the side panel 56 on the main shade 20 side overlaps or collides with the side of the main shade 20 in the thickness direction. 1 sub-shielding part is shielded. That is, the subshade 60 and the side panel 56 may be configured to suppress light leakage from between the subshade 60 and the side shade 56.

  However, the sub shade 60 may be attached so as to overlap the entire vehicle interior side of the movable rail 50, and may be formed in a size and shape that can shield the entire sub shielding portion of the window 1 by itself. In this case, the sub-shade 60 may be formed such that the end portion on the main shade 20 side corresponds to the shape of the side of the main shade 20.

  The interlocking mechanism part 70 is a part that moves the movable rail 50 between the advanced position and the retracted position in conjunction with the movement of the drawer member 40 in the drawer storage direction P (see FIG. 6). The interlocking mechanism unit 70 is configured to be able to transmit the force that moves the pulling member 40 in the pulling and storing direction P to the force that moves the movable rail 50 between the advanced position and the retracted position. The interlocking mechanism unit 70 includes an advancing / retreating link 72, a regulating mechanism unit, and an urging member 82.

  The forward / backward link 72 is a part that directly moves the movable rail 50. The advancing / retreating link 72 is connected to the movable rail 50 so as to be rotatable relative to the movable rail 50, and the posture is changed between an advancing posture for moving the movable rail 50 to the advanced position and a retracting posture for moving the movable rail 50 to the retracted position. Is done. The advance / retreat link 72 includes a main body portion 73 and an interlocking receiving portion 74.

  The main body 73 is a portion formed in a plate shape elongated in one direction. And the main-body part 73 is connected so that relative rotation with respect to the base end side (winding device 30 side) part of the movable rail 50 is possible, and the regulation mechanism part which two points of an other end side part mention later. The pair of restriction links 76 and 78 are connected to each other so as to be relatively rotatable. Moreover, the main-body part 73 is formed in the shape for which the one end side part was tapering so that it may not come out to the main shade 20 side from the movable rail 50 (subshade 60) in the advance position in the attitude for advance (FIG. 8). Here, the main-body part 73 is formed in the shape which has the side along the main shade 20 side edge part of the movable rail 50 (subshade 60) in an advance position.

  The interlocking receiving portion 74 surrounds an internal space in which the interlocking protrusion 46 of the runner 44 can be disposed with an enclosing wall, and an opening through which the interlocking protrusion 46 can enter and exit in a part of the surrounding wall in the circumferential direction. 75 is a portion formed. The interlocking receiving portion 74 is formed in a shape protruding from one main surface of the main body portion 73.

  Here, the interlocking protrusion 46 and the interlocking receiving portion 74 will be described in more detail along with the mutual relationship (see FIG. 10).

  The interlocking protrusion 46 is formed in a shape that protrudes in a direction substantially orthogonal to the operation plane of the main shade 20 in a part of the runner 44. The interlocking protrusion 46 is formed in a shape in which a dimension in one direction is set smaller than a dimension in another direction in a cross-sectional view orthogonal to the protrusion direction. Here, the interlocking protrusion 46 is formed in a columnar shape having an outer peripheral portion in which a circular arc portion (in this case, an arc larger than 180 degrees) and a linear portion connecting both ends thereof are combined in a cross-sectional view orthogonal to the protrusion direction. Yes. That is, the interlocking protrusion 46 has the smallest dimension in the direction orthogonal to the straight line portion in the radial direction with respect to the central axis of the arc portion. Here, the interlocking protrusion 46 is formed in a shape in which the linear portion is along the drawer housing direction P on the middle side in the longitudinal direction of the drawer member 40.

  On the other hand, the interlocking receiving portion 74 is configured such that an enclosing wall is erected on one main surface of the main body portion 73 so as to surround a substantially cylindrical internal space. The interlocking receiving part 74 is set so that the opening 75 opens with a dimension that is the same as or slightly larger than the dimension in the direction orthogonal to the linear part of the interlocking protrusion 46. That is, the interlocking receiving portion 74 can insert and remove the interlocking protrusion 46 in a posture in which the linear portion of the interlocking protrusion 46 is along the opening direction of the opening 75. In other words, the interlocking receiving portion 74 is configured such that, when the linear portion of the interlocking protrusion 46 is not along the opening direction of the opening 75, the surrounding wall abuts on the outer peripheral portion of the interlocking protrusion 46. The portion 46 is prevented from coming out of the opening 75 (see FIG. 9). In addition, here, the interlocking receiving portion 74 is a circle in which one end portion of the surrounding wall (the end portion located on the end portion side of the drawer member 40 in the advancement posture) is in the opening direction of the opening portion 75 and the surrounding wall is along. It is formed in a shape extending in the tangential direction.

  When the pullout member 40 is moved in a state in which the interlocking protrusion 46 is disposed in the interlocking receiving part 74, the interlocking receiving part 74 is moved along the drawer storing direction P. Thus, the posture is changed (see FIG. 9). That is, the advancing / retreating link 72 is arranged to move while rotating around the interlocking receiving portion 74.

  The advancing / retreating link 72 is maintained in a posture in which the opening 75 of the interlocking receiving portion 74 is directed toward the drawing-out / accommodating direction P with the movable rail 50 in the advanced position (see FIG. 10). In this posture, the runner 44 is positioned between the position where the interlocking protrusion 46 is disposed in the interlocking receiving part 74 and the position where the interlocking protrusion 46 exits from the interlocking receiving part and is guided to the movable rail 50. It is a posture that makes it possible to move between.

  Further, the forward / backward link 72 has an enclosure wall on the storage side in the drawer storage direction P in the advancement posture. That is, when the pulling member 40 is moved to the storage direction P storage side in the state where the interlocking protrusion 46 is disposed in the interlocking receiving portion 74, the surrounding wall is pressed by the interlocking protrusion 46. The advancing / retreating link 72 is moved to the retracting and storing direction P storing side while rotating around the interlocking receiving portion 74. And the surrounding wall of the interlocking receiving part 74 in the advancing / retreating link 72 whose attitude is changed from the advancing attitude exists on both sides of the drawer storage direction P. That is, when the drawer member 40 is moved in the drawer storage direction P, the surrounding wall is pressed by the interlocking projection 46, and the advancing / retreating link 72 rotates around the central axis of the interlocking receiving portion 74 while being in the drawer storage direction. It is moved to the P storage side or the drawer side.

  The posture change of the advancing / retreating link 72 is regulated by a regulation mechanism unit. The restriction mechanism portion is configured to uniformly restrict the posture change between the advancement posture and the retracting posture of the advance / retreat link 72 so that the interlocking receiving portion 74 moves along the drawer housing direction P. (See FIGS. 6 to 8). The restriction mechanism includes a pair of restriction links 76 and 78.

  Each of the pair of restriction links 76 and 78 is supported so that one end portion thereof is rotatable around an axis that is relatively fixed with respect to the winding device 30, and the other end portion is another portion of the advance / retreat link 72. The part is rotatably connected. Here, one end portions of the pair of regulation links 76 and 78 are supported so as to be relatively rotatable around an axis with respect to different portions of the base 32 (or the vehicle body) of the winding device 30. That is, the advancing / retreating link 72 is supported on the base 32 by the pair of restriction links 76 and 78. Further, the movable rail 50 connected to the advance / retreat link 72 is also indirectly supported by the base 32.

  Then, the advancing / retreating link 72 is moved while the posture is changed in a posture corresponding to the position of each of the other end portions of the pair of regulation links 76 and 78 whose posture is changed. More specifically, when the line connecting the other end portions of the pair of restriction links 76 and 78 maintained at a constant interval is tilted by the posture change of the pair of restriction links 76 and 78, the forward / backward link 72 is inclined. The posture is changed around the central axis of the interlocking receiving portion 74 by the inclination. Further, the advancing / retreating link 72 moves along the drawer / housing direction P together with the posture change by the movement of the other end portion of the pair of restriction links 76 and 78 due to the posture change.

  The urging member 82 is a member for maintaining the advance / retreat link 72 in the advance posture and the retracted posture. More specifically, the urging member 82 urges the advancing / retreating link 72 toward the advancing posture side in a posture closer to the advancing posture than the predetermined posture, and closer to the retracting posture than the predetermined posture. In such a manner, it is biased toward the retracting posture side.

  The biasing member 82 is configured to be biased in a direction extending in one direction. For example, a configuration in which a coil spring is disposed between the base and the advancing / retreating part provided so as to be movable between the advance position and the retracted position with respect to the base, and the advance / retreat part is biased toward the advance position by the coil spring. Can be adopted.

  Here, the urging member 82 has one end connected to the other end of the one restriction link 76 and the other end connected to the base 32 (or the vehicle body) of the winding device 30 so as to be relatively rotatable. Has been. That is, when the connecting portion between the other end of one restriction link 76 and one end of the urging member 82 crosses a line connecting one end of one restriction link 76 and the other end of the urging member 82, The biasing direction is switched to the side where the connecting portion is located with respect to the line.

  In addition, the movable rail 50 moved by the interlocking mechanism unit 70 is regulated by the rail posture regulation unit 86 so that the posture change in the movement between the advanced position and the retracted position is fixed. The rail posture restricting portion 86 is supported such that one end thereof is rotatable around an axis located at a fixed position relative to the winding device 30, and the other end is coupled to the movable rail 50. Here, it is preferable that one end portion of the rail posture restricting portion 86 is connected to the tip side portion of the movable rail 50 and the other end portion is supported on the vehicle side (vehicle body panel or the like). In other words, the rail posture restricting portion 86 is configured to guide the movable rail 50 along a path in which one end moves in the circumferential direction around the other end.

  The drive mechanism 90 is a part that moves the drawer member 40 along the drawer storage direction P to pull out and store the main shade 20 (see FIGS. 1 and 2). The drive mechanism unit 90 includes a flexible rack member 92 and a rack drive unit 94.

  The flexible rack member 92 is a member in which a plurality of teeth are formed on one surface of a long plate shape along the longitudinal direction. A pair of the flexible rack members 92 is provided corresponding to the pair of runners 44, and is connected to the drawer storage direction P storage side of the runners 44. Further, the flexible rack member 92 is guided by a guide unit (not shown) along a path along the extending direction of the movable rail 50 from the rack driving unit 94 toward the base end side position of the movable rail 50 at the advanced position. It is arranged so that. Further, the flexible rack member 92 is inserted into the rack groove portion 54 in a state where the groove portion 48 of the runner 44 is fitted to the guide protrusion 52 of the movable rail 50.

  Then, by moving the pair of flexible rack members 92 in the longitudinal direction, the pair of runners 44 is moved, and the main shade 20 is pulled out and stored.

  The rack driving unit 94 is a part that moves the flexible rack member 92 in the longitudinal direction. As this rack drive part 94, the structure containing the gear which meshes with a pair of flexible rack member 92, and the motor which rotationally drives a gear via a transmission gear etc. is employable. The rack drive unit 94 may be fixed to the base 32 of the winding device 30. However, the rack drive unit 94 may be fixed relative to the winding device 30 by being fixed to a vehicle body panel or the like of the vehicle to which the shade device 10 is attached.

<Operation of shade device>
Next, the operation of the shade device 10 will be described. First, the operation of shielding the window 1 will be described. As an initial state, the shade device 10 assumes that the main shade 20 is in the retracted state and the movable rail 50 (subshade 60) is in the retracted position (see FIGS. 1 and 6).

  First, a pair of flexible rack members 92 are sent out by the rack drive unit 94 toward the drawer storage direction P drawer side (see FIG. 7). Thereby, the drawer member 40 is moved toward the drawer storage direction P drawer side. As a result, the interlocking protrusion 46 of the runner 44 linearly presses the interlocking receiving portion 74 toward the drawer storage direction P drawer side. The advancing / retreating link 72 is changed in posture from the retracting posture to the advancing posture while being moved by the pair of restriction links 76 and 78 while moving in the drawing / housing direction P drawing side. Accordingly, the movable rail 50 is moved from the retracted position toward the advanced position.

  At the beginning of the attitude change of the advance / retreat link 72, the advance / retreat link 72 is urged toward the retracting attitude by the urging member 82, and the withdrawal member 40 is pulled out against this urging force. Change posture. When the advancing / retreating link 72 exceeds a predetermined posture, the advancing / retreating link 72 is urged toward the advancing posture side by the urging member 82. As a result, the advancing / retreating link 72 is maintained in the advancing posture after the posture is changed to the advancing posture. The movable rail 50 is also maintained at the advanced position after being moved to the advanced position. Here, the movable rail 50 is perpendicular to the winding shaft portion 34.

  Further, the auxiliary shade 60 attached to the movable rail 50 is pulled out onto the window 1 as the movable rail 50 is moved toward the advanced position.

  Then, when the forward / backward link 72 is changed to the advancement posture and the movable rail 50 is moved to the advancement position, the side panel 56 (the subshade 60 may overlap) is connected to the subshield portion of the window 1. Against the vehicle interior side (see FIGS. 2 and 8).

  In the state where the movable rail 50 is moved to the advanced position, the groove portion 48 and the flexible rack member 92 of the runner 44 are moved from the proximal end side to the guide protrusion portion 52 and the rack groove portion 54 in the longitudinal direction of the movable rail 50. It arrange | positions in the position which opposes (refer FIG. 4). Further, in the advance / retreat link 72, the interlocking receiving portion 74 has the opening portion 75 directed toward the drawer storage direction P drawer side (see FIG. 10).

  When the pull-out member 40 is further moved in the pull-out storage direction P pull-out side, the interlocking projection 46 of the runner 44 is pulled out from the interlocking receiving portion 74 of the advance / retreat link 72 through the opening 75 to the pull-out side. Thereby, the groove 48 of the runner 44 is fitted into the guide protrusion 52 of the movable rail 50, and the flexible rack member 92 is inserted into the rack groove 54 (see FIG. 5). Further, when the flexible rack member 92 is sent out, the runner 44 moves the movable rail 50 toward the pull-out storage direction P pull-out side, and the main shade 20 is pulled out. Then, the drawing member 40 is moved until the main shade 20 is in a drawing state in which the main shielding portion of the window 1 is shielded. The pull-out operation of the main shade 20 may be stopped by stopping the feed-out operation of the flexible rack member 92 by the drive mechanism 90.

  With the above operation, the window 1 is entirely shielded by the main shade 20 and the subshade 60 (and the side panel 56 of the movable rail 50).

  Next, an operation for making the window 1 unshielded will be described.

  First, the pair of flexible rack members 92 are sent back toward the storage side P in the drawer storage direction by the rack driving unit 94. Thereby, the drawer member 40 is moved toward the drawer storage direction P storage side, and the main shade 20 is wound up by the winding attachment force of the winding device 30. When the drawing member 40 is moved beyond the base end portion of the movable rail 50, the interlocking projection 46 of the runner 44 enters the interlocking receiving portion 74 of the advance / retreat link 72 through the opening 75 (see FIG. 10). At this time, the groove 48 of the runner 44 is disengaged from the guide protrusion 52 of the movable rail 50, and the flexible rack member 92 comes out of the rack groove 54 (see FIG. 4).

  When the flexible rack member 92 is further fed back, the interlocking protrusion 46 that has entered the interlocking receiving portion 74 presses the interlocking receiving portion 74. Then, the advancing / retreating link 72 is changed in posture from the advancing posture to the retreating posture while being moved by the pair of restriction links 76 and 78 while moving in the drawer / housing direction P storage side. Accordingly, the movable rail 50 is moved from the retracted position toward the advanced position.

  At the beginning of the attitude change of the advance / retreat link 72, the advance / retreat link 72 is urged toward the advance attitude by the urging member 82, and the drawing member 40 moves to the storage side against this urging force. The posture is changed by being done. When the advancing / retreating link 72 exceeds a predetermined posture, the advancing / retreating link 72 is urged toward the advancing posture side by the urging member 82. Thereby, the advancing / retreating link 72 is maintained in the retracting posture after the posture is changed to the retracting posture. The movable rail 50 is also maintained at the retracted position after being moved to the retracted position. Here, the movable rail 50 is disposed in the lateral vertical frame 1 </ b> C of the window 1.

  When the forward / backward link 72 is changed to the retracted posture and the movable rail 50 is moved to the retracted position, the sub-shade 60 is retracted from the sub-shielding portion of the window 1 and accommodated in the side vertical frame 1C. (See FIGS. 1 and 6). Further, when the advance / retreat link 72 is changed to the retracted posture, the pull-out member 40 contacts the interlocking protrusion 46 with the interlocking receiving portion 74, and the flexible rack member 92 is driven by the driving mechanism 90. The main shade 20 is not further wound by the winding device 30 due to the stop. In this state, the drawing member 40 is preferably disposed in the ceiling side horizontal frame 1A.

  By the above operation, the main shade 20 and the sub shade 60 are accommodated.

  According to the shade device 10 according to the above embodiment, at least one of the pair of guide rails in which the pair of runners 44 can be fitted so as to be movable along one direction is shielded by the main shade 20 of the window 1. The movable rail 50 is connected to a sub-shade 60 that can shield a side portion of the portion to be shielded. The movable rail 50 draws and stores the runner 44 and a retracted position where the sub-shade 60 is retracted to the side of the window 1. The auxiliary shade 60 is provided so as to be able to guide along the direction P and to be movable between advancing positions that shield the side portions of the window 1 that are shielded by the main shade 20. For this reason, even if the main shade 20 is not expanded and contracted, the portion that cannot be shielded by the main shade 20 can be shielded by the sub shade 60 and the window 1 can be shielded as a whole. As a result, the window 1 can be shielded while suppressing wrinkles and slack in the pulled-out state of the main shade 20.

  Here, since the main shade 20 is formed in a rectangular shape, it is possible to more reliably suppress the occurrence of the shape difference, deflection, and wrinkles on both sides during drawing.

  Further, since the sub-shade 60 is moved out and out by the movable rail 50, a winding device for the sub-shade 60 is not required, and the structure can be simplified and the structure can be simplified. But the subshade 60 may be arrange | positioned so that it may be wound up with a winding device.

  In addition, since the interlocking mechanism portion 70 that moves the movable rail 50 between the advanced position and the retracted position in conjunction with the movement of the pull-out member 40 in the pull-out storage direction P is provided, 60 can be advanced, and the operability is improved.

  Further, since the interlocking mechanism unit 70 transmits the force that moves the pulling member 40 in the pulling and storing direction P to the force that moves the movable rail 50 between the advanced position and the retracted position, the pulling operation of the main shade 20 is performed. By doing so, the auxiliary shade 60 can be moved back and forth without using the drive source for moving the auxiliary shade 60 back and forth.

  The interlocking mechanism 70 is connected to the movable rail 50 so as to be relatively rotatable, and surrounds the internal space with the surrounding wall and has an opening 75 formed in a part of the circumferential direction of the surrounding wall. The forward / backward link 72 including the forward / backward link 72, the forward / backward link 72, the movable rail 50 is moved to the advanced position, and the opening position of the interlocking receiving portion 74 toward the drawer storage direction P drawer side, and the movable rail And a restricting mechanism portion that supports the opening portion 75 of the interlocking receiving portion 74 in such a manner that the opening portion 75 can be changed in a posture that is inclined in the pull-out storage direction P. The runner 44 guided by the movable rail 50 can enter and exit through the opening 75 in the interlocking receiving portion 74 of the advancing / retreating link 72 in the advance posture, and is disposed in the interlocking receiving portion 74. An interlocking protrusion 46 capable of pushing the advance / retreat link 72 is included. For this reason, the movable rail 50 can be moved forward and backward by changing the posture of the advancing / retreating link 72 by the movement of the interlocking protrusion 46 disposed in the interlocking receiving portion 74, and the drawer member 40 can be operated with a simpler configuration. The subshade 60 can be moved forward and backward by transmitting the moving force.

  Further, since the pair of restricting links 76 and 78 restricts the posture change of the advancing / retreating link 72 so that the interlocking receiving portion 74 moves linearly along the pulling out and storing direction P, the pulling member 40 is long. The direction extension / contraction mechanism can be omitted, the main shade 20 can be pulled out and stored in a more stable form, and the deviation (left-right difference), looseness, wrinkles, and the like in the width direction of the main shade 20 can be more reliably suppressed.

  In addition, each of the regulating mechanism portions is supported so that one end portion thereof is rotatable around an axis that is relatively fixed with respect to the winding device 30, and the other end portion is provided on another portion of the advance / retreat link 72. Since it is comprised by a pair of control links 76 and 78 connected so that rotation is possible, the moving force of the drawer | drawing-out member 40 can be transmitted with a simpler structure, and the subshade 60 can be moved forwards or backwards.

  Further, the interlocking mechanism unit 70 urges the advancing / retreating link 72 toward the advancing posture side in a posture closer to the advancing posture than the predetermined posture, and for retreating in a posture closer to the retreating posture than the predetermined posture. Since the urging member 82 is provided so as to urge toward the posture side, the movable rail 50 can be reliably maintained in each of the advanced position and the retracted position.

  The driving mechanism 90 includes a flexible rack member 92 connected to the drawer storage direction P storage side of the pair of runners 44 and a rack driving unit 94 that moves the flexible rack member 92 in the longitudinal direction. Therefore, even in the configuration in which the pullout member 40 is guided by the movable rail 50, the main shade 20 can be automatically pulled out and stored in a simpler and more compact form.

  In addition, since the bent portions of the pair of flexible rack members 92 can be made into one place with a simple configuration, the load fluctuation of the flexible rack members 92 is suppressed, and smooth operation and stable performance are exhibited. it can.

  Moreover, since the rail attitude | position control part 86 which controls the movable rail 50 to move by a fixed path | route between an advance position and a retracted position is provided, the movement of the movable rail 50 can be stabilized.

  So far, the example in which the main shade 20 is pulled out and stored by moving the pulling member 40 in the pulling out and storing direction P by the drive mechanism unit 90 has been described, but the pulling member 40 may be moved manually. When the drawer member 40 is manually moved as described above, the drawer member 40 is further wound up in a state where the main shade 20 is wound up by the winding device 30 and retracted into the ceiling side horizontal frame 1A. It is good to be comprised so that it may latch with respect to the winding device 30 or some vehicle bodies so that it may not exist. In addition, even if the structure for the drawing member 40 to latch with respect to the winding device 30 may be formed in the drawing member 40 side, it may be formed in the winding device 30 or the vehicle body side. Moreover, in order to maintain the main shade 20 in a drawer | draw-out state, it is good for the latching structure to be provided in either or both of the drawer member 40 and the floor side horizontal frame 1B.

  Moreover, the subshade 60 should just be formed so that the subshielding part of the window 1 can be shielded, and is not restricted to the sheet | seat shape as mentioned above. Hereinafter, three modifications of the subshade 60 will be given. However, it is also possible to adopt shapes other than the following subshade.

  In the subshade 601 according to the first modification, the sheet-like members are alternately mountain-folded and valley-folded so that the movable rail 50 can be compactly stored in the side vertical frame 1C when the movable rail 50 is moved to the retracted position. It is formed in a bellows shape (see FIGS. 11 to 13). That is, the sub-shade 601 is in a form in which the crests and troughs are contracted close to each other with the movable rail 50 in the retracted position, and the crests and troughs are separated and expanded when moved forward. It becomes a form.

  The auxiliary shade 602 according to the second modification is formed in a plate shape obtained by molding a synthetic resin material (see FIGS. 14 to 16). The sub-shade 602 may be formed separately from the movable rail 50 or may be formed integrally therewith.

  The sub-shade 603 according to the third modification includes a plurality of plate-like members, and is large enough to shield the sub-shielding portion when the plurality of plate-like members are shifted laterally from a state where they overlap in the thickness direction. It is formed in a shape that can be expanded (see FIGS. 17 to 19). More specifically, each of the plurality of plate-like members is formed into an elongated plate shape, and one protrusion along the one side edge protruding from one surface side of the one side edge along the longitudinal direction. A strip portion and the other ridge portion along the other side edge portion protruding from the other surface side of the other side edge portion are provided. That is, the sub-shade 603 has a configuration in which the plurality of plate-like members overlap each other in the thickness direction when the movable rail 50 is in the retracted position. The protruding portion is hooked on one protruding portion of the other plate-like member to pull out the other plate-like member. And the subshade 603 becomes a form where a plurality of plate-like members are similarly pulled out and expanded.

  Further, the drive mechanism unit 90 is not limited to the combination of the flexible rack member 92 and the rack drive unit 94. For example, the drive mechanism unit 90 employs a configuration in which a rod-like member connected to the runner 44 is moved along the drawer storage direction P. Also good.

  Further, although the example in which both of the pair of guide rails are the movable rails 50 has been described, only one of the guide rails may be the movable rail 50 and the other may be a guide rail to which the sub shade 60 is not connected. The guide rail may be disposed in the side vertical frame 1C and fixed to the vehicle body.

  Moreover, the interlocking mechanism part 70 is not restricted to the structure mentioned above. For example, the interlocking mechanism portion is provided with two protrusions on the advancing / retreating link instead of the pair of restricting links 76 and 78 for restricting the posture change of the advancing / retreating link 72, and guides the two protrusions on the base 32. It is also possible to employ a configuration in which guide grooves are provided. Further, as the interlocking mechanism part, an electric interlocking mechanism part having a driving part such as an air cylinder or a motor may be employed. For example, a configuration in which the movable rail 50 is moved from the retracted position to the advanced position by the drive unit in response to the operation start signal output from the drive mechanism unit 90 can be employed.

  Further, the interlocking mechanism unit 70 may be omitted, and the movable rail 50 may be configured to be manually movable from the retracted position to the advanced position. For example, it is possible to employ a configuration in which the movable rail 50 is supported by a link or the like so as to be movable between the retracted position and the advanced position, and can be operated by providing a moving handle.

  Further, although the example in which the winding device 30 is disposed in the ceiling side horizontal frame 1A of the window 1 has been described, the winding device 30 may be disposed in the floor side horizontal frame 1B. Also in this case, a side portion of the window 1 that is shielded by the main shade 20 drawn out from the winding device 30 disposed in the floor side frame 1B is covered by the sub shade 60 (movable rail 50). What is necessary is just to be comprised so that it may shield.

  Moreover, although the movable rail 50 has been described as an example along the direction perpendicular to the winding shaft portion 34 at the advanced position, the movable rail 50 may be inclined with respect to the direction perpendicular to the winding shaft portion 34. In this case, the drawing member 40 may be configured to be extendable and contractible in the longitudinal direction corresponding to the interval between the pair of movable rails 50. For example, the drawing member can employ a configuration in which the stay is formed in a cylindrical shape and the runner is inserted so as to be movable in the longitudinal direction with respect to the stay.

  Further, if the drawing member adopts a configuration in which the drawing member can be expanded and contracted in the longitudinal direction, the restriction mechanism portion changes the posture so that the advancement / retraction link 72 moves linearly along the drawing / housing direction P. Even if not, the runner 44 can be guided and the movable rail 50 can be moved. The restricting mechanism portion guides the interlocking protrusion 46 to a position where the interlocking receiving portion 74 directs the opening 75 toward the pull-out storage direction P-drawing side and the runner 44 can be fitted to the movable rail 50 in the advance posture. As described above, it is preferable that the posture change of the advance / retreat link 72 can be restricted.

  Further, the fitting form of the movable rail 50 and the runner 44 is not limited to the combination of the guide protrusion 52 and the groove 48. That is, if the movable rail 50 and the runner 44 are not relatively movable in the direction perpendicular to the longitudinal direction of the movable rail 50 and the interlocking projection 46 is exposed so as to be able to enter and exit the interlocking receiving portion 74. Other uneven fittings may be employed.

  Further, the interlocking protrusion 46 and the interlocking receiving part 74 are capable of moving the advance / retreat link 72 relative to the runner 44 in the advancing attitude, and cannot move in any other attitude (relative rotation is possible). The configuration is not limited to the above combination. For example, the interlocking protrusion and the interlocking receiving part may be set in reverse shapes. That is, in a state where the advance / retreat link is in the advancement posture, the linear portion of the projection-like interlocking receiving portion formed on the advance / retreat link is along the drawer storage direction P, and is substantially C-shaped interlocking formed on the runner. It becomes possible to enter / exit through the opening 75 through the opening 75, and the interlocking receiving part cannot come out of the interlocking protrusion when the forward / backward link is in any other posture.

  Moreover, the rail attitude | position regulation part 86 may be formed in the groove | channel shape which provides a protrusion in the movable rail 50 and guides this protrusion not only in a link.

  The shade device 10 can also be applied to windows other than rear windows and windows other than trapezoids. Also in this case, it is only necessary that the portion of the window that can be shielded by the main shade 20 is covered with the sub shade.
