More specifically, the guiding portion extends along the radial direction with respect to the central axis of the locking activation portion 92 in the extended posture. Note that the stopper 96 is maintained in the extended posture in a state where an external force around the central axis of the drawing-side drum 72 is not applied. As described above, the stopper urging portion 97 is set to have a larger urging force than the retracting urging portion 86 and smaller than the drawing-side rotation urging portion 78.

  When the pull-out side wire 52 is pulled out and the pull-out side drum 72 is rotated, the locking activation portion 92 is rotated by the pull-out side drum 72 via the urging biasing portion 86 (see FIG. 9). When the drawing-out drum 72 is rotated to a position where the projecting portion 94 comes into contact with the stopper 96 and the rotation further proceeds, the movement of the projecting portion 94 is restricted by the guide portion, thereby restricting the rotation of the locking activation portion 92 ( (See FIG. 10). In other words, the urging force for the stopper 96 to restrict the rotation of the locking activation portion 92 by the stopper urging portion 97 is set larger than the urging force for the retracting urging portion 86 to maintain the locking activation portion 92 in the non-locking maintenance state. Has been. For this reason, the locking starter 92 that is rotationally restricted with respect to the rotated draw-out side drum 72 rotates relative to each other, the retracting biasing part 86 is compressed, and the lock starter 92 is moved relative to the drawout side drum 72. The posture is changed from the non-locking maintenance state to the locking maintenance state. Note that the state where the urging urging portion 86 is compressed here refers to a state in which the urging portion 86 is compressed to the maximum or the urging force by which the stopper 96 regulates the rotation of the locking activation portion 92 by the stopper urging portion 97. The urging portion 86 is compressed to an extent that the urging force for maintaining the locking activation portion 92 in the non-locking maintaining state is increased. When the drawing-side drum 72 is further rotated from here, the locking starter 92 is rotated together with the drawing-side drum 72 through the compressed urging biasing portion 86, and the protruding portion 94 gets over the guiding portion (FIG. 11). reference).

<Drawer hold release mechanism>
The drawer holding release mechanism unit is a part that releases the holding state of the drawer member 30 by the drawer holding mechanism unit 40 and stores and operates the sheet-like member 20 by remote control (see FIGS. 1 and 2). Here, the drawer holding release mechanism portion includes a release wire 53. One end portion of the release wire 53 is fixed to the rear end portion of the slider portion 41 of the drawer holding mechanism portion 40, and the other end portion is drawn out from the roof console 18 through the inside of the roof liner 16 of the vehicle. The support base 48 may be formed with a through hole portion through which the release wire 53 is inserted. But the support base 48 may have one through-hole part which can penetrate the extraction | drawer side wire 52 and the cancellation | release wire 53 collectively. And from the roof console 18, the other end part of the drawer side wire 52 and the other end part of the cancellation | release wire 53 are extended in the vehicle interior. Further, the other end portion of the release wire 53 is preferably provided with a handle portion 531 for operation.

  When the release wire 53 is pulled and released while the drawer holding mechanism 40 holds the drawer member 30, the slider 41 is drawn into the support base 48 and the cam follower 47 moves in the cam 42. At the same time, it is moved to the advance position by the urging force of the advance urging unit 49.

<Storage deceleration part>
The storage speed reducing unit 68 pulls the release wire 53 from the pulled-out state of the sheet-like member 20, and the pulled-out member 30 collides with the inside of the vehicle interior when the held state of the pulled-out member 30 by the pulled-out holding mechanism unit 40 is released. This is a part for suppressing this (see FIG. 7). That is, the drawing member 30 released from the holding state by the drawing holding mechanism 40 may collide with the interior of the vehicle interior with a strong force due to its own weight and the winding force of the sheet-like member 20 of the winding device 22.

  For example, a hydraulic damper that relaxes the rotation of the shaft portion 66 of the seat-side drum 62 with respect to the first case 55 can be employed as the storage speed reducing portion 68. Hereinafter, an example in which this configuration shown in FIG. 7 is adopted will be described. Further, the storage speed reducing unit 68 can contact the outer peripheral surface of the moving sheet side wire 51 to give resistance, and can reduce the movement of the drawing member 30.

<Operation>
Next, the operation of the entire sheet drawer storage device 10 will be described. As an initial state, it is assumed that the sheet-like member 20 is stored in the winding device 22 (see FIGS. 8 and 14).

  The operation | movement which shields the window 12 with the sheet-like member 20 is demonstrated.

  First, the drawer-side wire 52 is pulled into the vehicle interior (see FIGS. 9 and 15). Thereby, the drawing-side wire 52 is drawn and the drawing-side drum 72 rotates.

  When the pull-out side drum 72 is further rotated from the position where the projecting portion 94 abuts on the guide portions (96, 97), the locking activation portion 92 is connected to the guide portion (96, 97) in the extended posture. The rotation is restricted by contact (see FIG. 10). As a result, the latch activation part 92 is rotated relative to the pull-out side drum 72 against the urging force of the retracting urging part 86, and pushes the latching part 82 by the latching pushing part 93. That is, the posture of the locking activation unit 92 is changed from the non-locking maintenance state to the locking maintenance state. In addition, the locking portion 82 is guided in the extending direction of the long hole portion 74 while being in contact with the locking pressing portion 93, and is not locked along the locking pressing portion 93. It moves to the outer peripheral side from the position toward the locking position. The locking portion 82 is locked to the locked portion 64 by the plurality of locking tooth portions 83 meshing with the plurality of locked tooth portions 65 formed on the seat side drum 62.

  Further, when the pull-out side wire 52 is pulled out, the protruding portion 94 of the locking activation portion 92 is moved over the guide portion and the pull-out side drum 72 is rotated (see FIG. 11). Then, the sheet side drum 62 is rotated while the locking portion 82 is locked to the locked portion 64, and the sheet side wire 51 is wound around the sheet side drum 62.

  Further, when the drawing side wire 52 is drawn and the sheet side wire 51 is wound around the sheet side drum 62 until the drawing member 30 pushes the slider portion 41 of the drawing holding mechanism portion 40 into the support base 48, the drawing holding mechanism portion. 40, the drawing member 30 is held between the pair of holding portions 43 (see FIGS. 5 and 16). Thereby, the sheet-like member 20 is maintained in the pulled-out state in which the window 12 is shielded (see FIG. 2).

  Then, when the drawing operation of the drawing side wire 52 is released, the drawing side drum 72 is rotated in the direction of winding the drawing side wire 52 by the urging force of the drawing side rotation urging unit 78 (FIGS. 12, 13, and FIG. 17). Then, the locking part 82 moves from the locking position to the non-locking position, and the locking state of the locking part 82 with respect to the locked part 64 is released. That is, due to the urging force of the urging urging portion 86, the locking activation portion 92 rotates relative to the drawing-side drum 72 from the locked maintenance state to the non-locking maintenance state. Thereby, the convex part 84 is guided to the extending direction of the long hole part 74, and the latching | locking part 82 is moved to an inner peripheral side toward a non-locking position from a latching position. Further, the protruding portion 94 of the locking activation portion 92 that is rotated together with the drawing-side drum 72 is rotated while over the guiding portion. That is, the biasing force that rotates the pull-out side drum 72 in the direction of winding the pull-out side wire 52 by the pull-out side rotation biasing portion 78 is caused by the stopper biasing portion 97 and the stopper 96 is rotated by the rotation of the locking activation portion 92 (projection portion 94). Is set to be larger than the urging force that restricts the movement of

  Next, the operation | movement which accommodates the sheet-like member 20 is demonstrated. Here, the release wire 53 is pulled toward the vehicle interior side (see FIG. 18). As a result, the slider 41 of the drawer holding mechanism 40 to which one end of the release wire 53 is fixed is drawn into the support base 48 and moved from the retracted position to the advanced position, and the pair of holding parts 43 with respect to the drawer member 30 is moved. The holding state is released (see FIG. 4). Then, the drawing member 30 moves in the direction close to the winding device 22 by the winding force and the own weight of the sheet-like member 20 of the winding device 22, and the sheet side wire 51 attached to the drawing member 30 is moved to the sheet side drum 62. Drawn from. At this time, the rotational speed of the sheet side drum 62 is attenuated with respect to the first case 55 by the storage speed reducing unit 68, and the movement of the drawing member 30 to which the sheet side wire 51 is attached is decelerated.

  And the sheet-like member 20 is wound up by the winding force of the winding device 22, and the sheet-like member 20 is maintained in the storage state which opened the window 12 (refer FIG. 1).

  According to the wire winding device 50 according to the first embodiment, one end portion with respect to the drawing member 30 provided at the drawing-side end portion of the sheet-like member 20 wound so as to be drawn and housed in the winding device 22. Is wound around the outer peripheral portion of a sheet side drum 62 supported so as to be relatively rotatable around the central axis with respect to the base portions 55 and 57, and the sheet side drum 62 and its own central axis are wound. The drawer-side wire 52 is arranged on the outer peripheral portion of the drawer-side drum 72 which is disposed so as to be relatively rotatable with respect to the sheet-side drum 62 and is supported so as to be relatively rotatable around the central axis with respect to the base portions 55 and 57. Is wound in the opposite direction to the sheet side wire 51. Further, the drawing-side drum 72 is urged to rotate in the direction in which the drawing-side wire 52 is wound around the bases 55, 57 by the drawing-side rotation urging unit 78, and the rotation regulating mechanism 80 is used to pull out the drawing-side wire 52. In conjunction with the relative rotation of the drawing-side drum 72 with respect to the base portions 55 and 57, the restriction-releasing state in which the relative rotation is released is changed to the restriction state in which the relative rotation is restricted, and the drawing-out operation of the drawing-side wire 52 is canceled. It is configured to return from the restricted state to the unregulated state in conjunction with the rotation of the draw side drum 72 by the accompanying draw side rotation urging portion 78. For this reason, when the drawer-side wire 52 is pulled out, the sheet-side drum 62 is rotated through the rotation regulating mechanism 80 together with the drawer-side drum 72, and the sheet-like member 20 can be pulled out by winding the sheet-side wire 51. Further, when the drawing operation on the drawing side wire 52 is released, the rotation restricting mechanism 80 returns to the restriction releasing state, and the drawing side drum 72 is rotated relative to the sheet side drum 62 by the drawing side rotation urging unit 78. The side wire 52 can be wound up. Thereby, the drawing-side wire 62 drawn during the drawing operation of the sheet-like member 20 can be automatically stored.

  The rotation restricting mechanism 80 is provided on one side in the central axis direction of the seat-side drum 62, and includes a locked portion 64 including a plurality of locked teeth 65 arranged in the circumferential direction, and a plurality of locked teeth. A locking portion 82 movably disposed between a locking position for locking with respect to the portion 65 and a non-locking position; In conjunction with the relative rotation of the drawing-side drum 72 with respect to 55 and 57, the drawing-side drum 72 is moved from the non-locking position to the locking position, and by the urging force of the drawing-side rotation urging portion 78 when the drawing-side wire 52 is released. It includes an exit / retreat mechanism 90 that moves from the locking position to the non-locking position in conjunction with the rotation of the drawing side drum 72. In this way, the locking portion 82 is moved back and forth to be locked and unlocked with respect to the plurality of locked tooth portions 65, thereby pulling out the sheet-like member 20 and the drawing-side wire after the drawing. 52 automatic storage can be realized.

  Further, the withdrawal / retraction mechanism 90 moves to the engagement maintaining posture in which the engagement portion 82 is pushed in the rotation direction of the extraction side drum 72 and maintained in the engagement position with respect to the extraction side drum 72. It includes a locking starter 92 that is supported so as to be relatively rotatable about the central axis with respect to the maintaining unlocking posture. For this reason, the pull-out side wire 52 is pulled out or wound, and the pull-out side drum 72 is rotated relative to the lock starting portion 92, whereby the lock portion 82 is locked to the lock portion 64. When the sheet side wire 51 is wound up and the locking portion 82 is released from the locked portion 64, the pulling side drum 72 causes the pulling side wire 52 to be pulled by the biasing force of the pulling side rotation biasing portion 78. Wind up. In this way, the sheet-like member 20 can be pulled out by operating the pull-out side wire 52, and the pull-out side wire 52 can be automatically stored.

  In addition, the drawer-side drum 72 includes a long hole portion 74 that extends while inclining inward and outward and in the rotation direction and opens in the central axis direction, and the locking portion 82 extends in the long hole portion 74 along the extending direction. The convex portion 84 is movably disposed, and when pushed in the rotational direction by the locking activation portion 92, the convex portion 84 is moved in the elongated hole portion 74 along the extending direction. It is moved inward and outward. For this reason, the movement mode between the non-locking position and the locking position of the locking portion 82 can be easily set by the shape of the long hole portion 74.

  Moreover, the latching activation part 92 includes a protruding part 94 projecting to the outer peripheral side, and the retracting mechanism part 90 moves the latching activation part 92 from the latch maintenance posture to the latch release posture with respect to the drawer-side drum 72. It is possible to project the retracting biasing portion 86 biasing toward the moving path of the protruding portion 94 of the locking activation portion 92 and to rotate the locking activation portion 92 relative to the drawing side drum 72. The base portions 55 and 57 are disposed so that the posture can be changed between the protruding posture and the retracted posture retracted from the movement path. For this reason, when the pull-out side wire 52 is pulled out and the latching activation part 92 is rotated together with the drawer-side drum 72, the protrusion 94 comes into contact with the guiding parts 96 and 97, so that the latching activation part 92 is pulled out. The posture is changed to the locking maintenance posture by being rotated relative to 72, and the locking portion 82 can be moved to the locking position. When the pulling-out force of the pull-out side wire 52 is released, the retracting biasing portion 86 changes the posture of the locking activation portion 92 to the locking release posture, and moves the locking portion 82 to the non-locking position. Can do. Then, the drawing-side wire 52 that is drawn by the drawing-side drum 72 being rotated by the urging force of the drawing-side rotation urging unit 78 can be automatically stored.

  Further, since the locked portion 64 includes a plurality of locked tooth portions 65 that are formed in a concave shape that opens at one side in the central axis direction of the seat side drum 72 and protrudes toward the inner peripheral side, The dimensions of the drum 62 and the rotation restricting mechanism 80 in the direction of the central axis can be further reduced, and the overall size can be reduced.

  Further, since the locking portion 82 includes a plurality of locking tooth portions 65 that can be locked with respect to the plurality of locked tooth portions 65 of the locked portion 64, the strength of the locking portion 64 is improved. Can do.

  So far, the wire take-up device 50 applied to the sheet draw-out storage device 10 that shields the rear window 12 has been described. However, the wire take-up device 50 can be used as a sheet draw-out storage device used as another window or tonneau cover device. Is also applicable.

  So far, the example in which the locked portion 64 is formed in a concave shape has been described, but a gear having a plurality of locked tooth portions protruding to the outer peripheral side may be used. It is preferable to set the shapes of the locking portion 82, the locking activation portion 92, and the long hole portion 74 so that the portion 82 operates so as to be locked to the plurality of locked tooth portions. For example, the locking portion may have a locking tooth portion toward the inner peripheral side, and the elongated hole portion may be formed in a shape that can be guided so that the locking portion moves toward the inner peripheral side.

  Further, although the example in which the long hole portion 74 is formed in the drawer-side drum 72 and the convex portion 84 is formed in the locking portion 82 has been described, the convex portion is formed in the drawer-side drum and the long hole portion is engaged. It may be formed at the stop.

  Further, although the example in which the guide portion is configured by the stopper 96 and the stopper biasing portion 97 has been described, the guide portion may be configured by a single elastic member.

  Moreover, the wire winding device 50 may include a sheet side rotation urging unit 67 (see FIGS. 19 and 20). The sheet-side rotation urging portion 67 is a portion that urges the sheet-side drum 62 to rotate with respect to the first case portion 55 so that the sheet-side wire 51 can be wound up in a state where the restriction of the rotation restricting mechanism portion 80 is released. That is, the sheet-side rotation urging unit 67 can urge the sheet-side drum 62 in a direction in which the sheet-side wire 51 is wound around the first case unit 55, that is, in a direction opposite to the drawing-side rotation urging unit 78. It is arranged. The seat side rotation urging portion 67 may be disposed between the first case portion 55 and the seat side drum 62. For example, the seat side rotation urging portion 67 may employ a spring or a coil spring.

  More specifically, the urging force of the sheet side rotation urging unit 67 is set to be large enough to allow the sheet side drum 62 to rotate while winding the sheet side wire 51 with respect to the first case unit 55. ing. Further, the urging force of the sheet side rotation urging portion 67 is large enough not to stop the movement of the drawing member 30 to the storage side due to the weight of the drawing member 30 and the winding force of the sheet-like member 20 by the winding device 22. Is set.

  The seat side rotation urging portion 67 may be provided together with the storage speed reducing portion 68 or may be provided after the storage speed reducing portion 68 is omitted. That is, the sheet side rotation urging portion 67 also contributes to a reduction in the moving speed of the drawing member 30 when the sheet-like member 20 is stored.

  According to this configuration, since the sheet-side drum is provided with the sheet-side rotation urging portion that urges the sheet-side drum to rotate relative to the base so that the sheet-side wire can be wound in the state where the rotation restriction mechanism portion is deregulated, the drawer member is manually operated. Even when the sheet-like member is pulled out by operating at, the sheet-side wire can be wound up. Thereby, slack and sagging of the sheet-side wire 51 when the drawer member 30 is manually operated can be suppressed. Further, slack and sagging of the sheet-side wire 51 inside the first case 55 and the second case 57 can be suppressed.

Second Embodiment
Next, the wire winding device 150 according to the second embodiment will be described (see FIGS. 21 and 22). In the wire winding device 150, the configuration different from the wire winding device 150 according to the first embodiment is a portion related to the drawer maintaining mechanism 140, and the same reference numerals are given to the same configuration, and the description is omitted. And the sheet | seat drawer | drawing-out accommodation apparatus 110 using the wire winding apparatus 150 becomes a structure which abbreviate | omitted the drawer | holding-out holding | maintenance mechanism part 40 in the sheet | seat drawer | drawing-out storage apparatus 10, instead of the wire winding apparatus 150 being provided with the drawing maintenance mechanism part 140. (See FIG. 25). In addition, it is good to have a groove-shaped and hole-shaped guide part (not shown) for guiding the sheet-side wire 51 routed in the roof liner 16 instead of omitting the drawer holding mechanism part 40.

  The wire winding device 150 includes a drawer maintaining mechanism 140 between the first case 155 and the sheet side drum 62. The drawer maintaining mechanism 140 is a part for maintaining the state in which the sheet-like member 20 attached to the drawer member 30 is pulled out. More specifically, the drawer maintaining mechanism 140 regulates the rotation of the sheet-side drum 62 so that the sheet-side wire 51 is caused by the weight of the drawer member 30 and the winding force of the sheet-like member 20 of the winding device 22. It is configured to stop being pulled out from the side drum 62.

  The drawer maintaining mechanism 140 includes a drawer maintaining locked portion 142, a drawer maintaining locking portion 144, and a locking biasing portion 148.

  The drawer maintaining locked portion 142 is a gear including a plurality of locked tooth portions 143 arranged in the circumferential direction. More specifically, the drawer-maintained locked portion 142 is provided on the other side in the central axis direction of the seat drum 62 (on the first case 155 side) so as not to be relatively rotatable. Here, the drawer-maintained locked portion 142 is formed integrally with the seat-side drum 62 so as to protrude from the central portion of the seat-side drum 62 on the first case 55 side.

  Further, the locked tooth portion 143 is formed in a sawtooth shape. More specifically, the plurality of locked tooth portions 143 of the pulling-maintained locked portion 142 have a surface that faces in the direction in which the sheet-side wire 51 of the sheet-side drum 62 is pulled out in the circumferential direction. It has an inclined surface on the opposite side.

  The drawer maintaining locking portion 144 is supported so that the posture can be changed between a locking posture and a non-locking posture in which the plurality of locked tooth portions 143 of the drawing maintenance locked portion 142 can be locked. It is the part which was done. The pulling-maintenance locking portion 144 is formed in a long shape in one direction, and has a locking tooth portion 145 at the tip. Here, the drawer maintaining locking portion 144 is pivotally supported at a position on the outer peripheral side of the drawer maintaining locked portion 142 such that a midway portion in the longitudinal direction is rotatable relative to the first case 55. More specifically, the drawer-maintaining locking portion 144 is supported so that its posture can be changed around an axis along the central axis of the seat-side drum 62. Accordingly, the pulling-maintenance locking portion 144 is configured so that the locking tooth portion 145 can be moved toward and away from the pulling-maintenance locked portion 142.

  Further, the drawer maintaining locking portion 144 can regulate the rotation in the direction in which the sheet side wire 51 is pulled out from the sheet side drum 62 with respect to the plurality of locked tooth portions 143 of the drawer maintaining locked portion 142. It has the surface which latches to.

  The locking biasing portion 148 is a portion that biases the drawer maintaining locking portion 144 in a direction in which the posture is changed from the non-locking posture to the locking posture. Here, the latching biasing portion 148 is a coil spring, and is between the spring receiving portion 147 provided at the proximal end portion of the pulling-maintaining locking portion 144 and the spring receiving portion 158 provided at the first case 155. In a compressed state. That is, the locking urging portion 148 urges the drawer maintaining locking portion 144 to rotate in a direction in which the locking tooth portion 145 comes close to the drawer maintaining locked portion 142.

  Further, the drawer maintenance mechanism 140 has a release wire 54 that can release the locked state of the drawer maintenance locking portion 144 with respect to the drawer maintenance locked portion 142. As with the sheet-side wire 51 and the lead-out side wire 52, the release wire 54 is a metal wire (including a wire in which a plurality of metal wires are twisted together), a metal wire coated with a synthetic resin or covered with a synthetic resin tube. A synthetic resin wire or the like may be employed.

  One end portion of the release wire 54 is fixed to the drawer maintaining locking portion 144, and the posture of the drawer maintaining locking portion can be changed to the non-locking posture by a drawing operation. More specifically, one end portion of the release wire 54 is fixed to the tip end portion of the pulling maintaining locking portion 144, and the other end portion is pulled out from the roof console 18 through the roof liner 16 of the vehicle. And from the roof console 18, the other end part of the drawer side wire 52 and the other end part of the cancellation | release wire 54 are extended in the vehicle interior. Further, an operation handle 541 may be provided at the other end of the release wire 54.

  Further, the first case 155 has a release wire insertion hole portion 59 that can draw the release wire 54 to the outside. That is, the release wire 54, one end of which is fixed to the drawer maintaining locking portion 144, is drawn from the inside of the base through the release wire insertion hole 59, and is drawn into the vehicle compartment through the roof console 18.

  Then, when the release wire 54 is pulled, the pulling maintaining locking portion 144 is changed from the locking posture to the non-locking posture. Thereby, the rotation restriction of the sheet side drum 62 is released, and the sheet side wire 51 is pulled out from the sheet side drum 62 by the weight of the drawing member 30 and the winding force of the sheet-like member 20 of the winding device 22. Further, when the pulling operation on the release wire 54 is released, the pulling maintaining locking portion 144 changes its posture toward the locking posture by the urging force of the locking urging portion 148, and the locked tooth portion 143 is moved to the locked tooth portion 143. Lock against. As a result, the rotation of the sheet side drum 62 is restricted again, and the drawing of the sheet side wire 51 is stopped. That is, the storing operation of the sheet-like member 20 is stopped.

<Operation>
The operation of the sheet drawing and storing device 110 including the wire winding device 150 will be described. Here, the description will be focused on the difference (particularly the drawer maintaining mechanism unit 140) from the sheet drawer storage device 10 according to the first embodiment, and description of similar operations will be omitted.

  First, the operation of pulling out the sheet-like member 20 will be described. That is, when the drawer-side wire 52 is pulled out, the sheet-side drum 62 is rotated in the direction in which the sheet-side wire 51 is wound up (see FIG. 26). Then, with the urging force of the locking urging portion 148, the locking tooth portion 145 of the drawer maintaining locking portion 144 is pressed against the outer peripheral portion of the locked tooth portion 143 of the drawing maintaining locked portion 142, It moves in and out along the outer peripheral surface (see FIG. 23). That is, when the sheet side drum 62 is rotated in the direction of winding the sheet side wire 51, the locking tooth portion 145 does not lock with respect to the plurality of locked tooth portions 143 and moves along the slope. . As the entire drawing maintaining locking portion 144, the posture change is continued between the locking posture and the non-locking posture.

  When the drawing operation on the drawing side wire 52 is canceled during the drawing of the sheet-like member 20, the locking tooth portion of the drawing maintaining locking portion 144 whose posture is changed to the locking posture by the urging force of the locking urging portion 148. 145 is locked to the locked tooth portion 143 of the drawer maintaining locked portion 142 (see FIG. 22). As a result, the rotation of the sheet side drum 62 in the direction in which the sheet side wire 51 is pulled out is restricted, and the storage of the sheet-like member 20 is restricted. That is, the sheet-like member 20 can maintain the halfway drawn state at a position between the housed state and the drawn state when being drawn.

  Next, when the sheet-like member 20 is drawn out (see FIG. 27) and the drawing operation on the drawing-side wire 52 is released (see FIG. 28), the engagement of the locking portion 82 with respect to the locked portion 64 is performed. The stop state is released, and the force in the direction in which the sheet-side drum 62 winds the sheet-side wire 51 is released. On the other hand, the sheet-side wire 51 is pulled by the own weight of the drawing member 30 and the winding force of the sheet-like member 20 of the winding device 22 because the drawing member 30 attached to the drawn sheet-like member 20 is attached. . That is, a force acts on the sheet side drum 62 in the direction of pulling out the sheet side wire 51 in the rotation direction. Similarly, the drawer-maintained locked portion 142 that is integrally formed with the sheet-side drum 62 also tries to rotate in the direction in which the sheet-side wire 51 is pulled out.

  On the other hand, in the drawer maintaining locking portion 144, the locking tooth portion 145 moves to the inner peripheral side by the urging force of the locking urging portion 148, and is locked to the plurality of locked tooth portions 143. (See FIG. 22). As a result, the rotation in the direction in which the sheet-side wire 51 of the sheet-side drum 62 integrally formed with the drawer-maintained locked portion 142 is pulled out is restricted. That is, the pulled-out state of the sheet-like member 20 is maintained.

  Next, the operation | movement which accommodates the sheet-like member 20 is demonstrated. Here, the release wire 54 is pulled to release the locked state of the drawer maintenance locking portion 144 with respect to the drawer maintenance locked portion 142 (see FIGS. 24 and 29). More specifically, when the release wire 54 is pulled, the pulling maintaining locking portion 144 is repelled by the biasing force of the locking biasing portion 148 and the posture is changed from the locking posture to the non-locking posture. Accordingly, the rotation restriction in the direction in which the sheet side wire 51 is pulled out with respect to the sheet side drum 62 is released.

  Then, the sheet-side wire 51 is pulled out from the sheet-side drum 62 by the weight of the sheet-like member 20 and the drawing member 30 and the winding force of the sheet-like member 20 of the winding device 22. That is, the sheet-like member 20 is wound and stored in the winding device 22. When the pulling operation with respect to the release wire 54 is canceled during the storage of the sheet-like member 20, the pulling maintaining locking portion 144 is changed from the non-locking posture to the locking posture by the biasing force of the locking biasing portion 148. The locking tooth portion 145 is locked to the locked tooth portion 143 of the drawer maintaining locked portion 142 (see FIG. 22). That is, the rotation in the direction in which the sheet-side wire 51 of the sheet-side drum 62 is pulled out is restricted, and the storage of the sheet-like member 20 is stopped. That is, the sheet-like member 20 can maintain the halfway drawn state at a position between the housed state and the withdrawn state even when housed.

  When the release wire 54 is pulled and the sheet-like member 20 is stored to the stored state, the drawing of the sheet-side wire 51 from the sheet-side drum 62 is stopped (see FIG. 25). At this time, the sheet-side wire 51 is preferably set to a length dimension that extends without slack along the window 12 between the drawing member 30 and the sheet-side drum 62.

  According to the wire take-up device 150 according to the second embodiment, the drawer maintenance device includes a plurality of engaged tooth portions 143 that are provided on the other side in the central axis direction of the sheet-side drum 62 so as not to rotate relative to each other and are arranged in the circumferential direction. The to-be-latched portion 142, the pulling-maintaining locking portion 144 supported so that the posture can be changed between the locking posture and the non-locking posture that can be locked to the plurality of locked tooth portions 143, and the drawer maintenance A locking biasing portion 148 that biases the locking portion 144 toward the locking posture, and one end portion of the locking portion 144 being fixed to the pulling maintenance locking portion 144 and the pulling operation locking portion 144 being unengaged by a pulling operation. Since the drawing maintaining mechanism 140 including the release wire 54 that can be changed to the stop posture is provided, the state where the sheet-like member 20 is pulled out can be maintained, and the operation of pulling the release wire 54 can be used to Cancel the drawer maintenance state Door can be.

  Moreover, the wire winding device 150 also has the same effect as the wire winding device 50 according to the first embodiment.

  As mentioned above, although the wire winding apparatuses 50 and 150 were demonstrated in detail, above-described description is an illustration in all the aspects, Comprising: This invention is not limited to it. The various modifications described above can be applied in combination as long as they do not contradict each other. And it is understood that the countless modification which is not illustrated can be assumed without deviating from the scope of the present invention.
