FIG. 5 is a front view of the locked member 13. FIG. 6 is an explanatory view for explaining a method of locking the locking member 8 to each locked member 13.

  As shown in FIGS. 1 to 3, the sunshade device 1 includes a window frame 3, a window 5 as an example of an object to be moved up and down through a window opening 3 </ b> A surrounded by the window frame 3, and the indoor side of the window 5. The sunshade 6 that functions as an example of a sheet material that is drawn out so as to cover the window 5 and shields the window 5, and the sunshade 6 is urged in the winding direction (downward in FIG. 1) and is wound so as to be drawn out. It is comprised from the winding storage apparatus 7 which takes in and stores.

  A substantially elongated locking member 8 is attached to the end edge of the sunshade 6 over the entire width. In addition, the take-up and storage device 7 is covered with a door trim 9 on the indoor side, and a horizontally long opening 9 </ b> A for pulling out the sunshade 6 is formed at the upper end of the door trim 9. In addition, a plate-like lever 11 is formed at the center in the longitudinal direction of the locking member 8 so as to project a predetermined length (for example, a length of about 3 cm) from the upper end to the room side.

  In addition, each locking hole 12 penetrating in a horizontally long rectangular cross section is formed at a position slightly closer to the center than both ends in the longitudinal direction of the locking member 8. On the other hand, at the upper edge of the window opening 3A of the window frame 3A, which is the peripheral part of the window opening 3A of the window frame 3 on the drawing direction side of the sunshade 6, the upper end of the locking member 8 is substantially at the peripheral part of the window opening 3A. The two to-be-latched members 13 to which the respective locking holes 12 are locked are provided at positions facing the respective locking holes 12 when pulled up to reach.

  As shown in FIGS. 1, 2, 4, and 5, the window frame 3 has a groove 3 </ b> B formed on the side facing the peripheral edge of the window 5, and a weather strip 4 that seals the peripheral edge of the window 5. It is fitted in the groove 3B. Each locked member 13 includes a substantially rectangular parallelepiped support portion 15 attached to the upper edge of the window opening 3A of the window frame 3 by screwing or the like, and a lower end portion of the support portion 15 in the indoor side direction, that is, A side view that functions as an example of a hook portion 16 that is rotatably supported in a direction that intersects the winding direction of the sunshade 6, and a rotation biasing member that biases the hook portion 16 toward the window 5. It is composed of an L-shaped leaf spring 17.

  The plate spring 17 having an L shape in side view extends downward from the flat plate portion 17A embedded so as to be substantially parallel to the flat lower end surface 15A of the support portion 15 and the edge of the flat plate portion 17A on the window 5 side. It is comprised from the protrusion part 17B taken out. The protruding portion 17B has a base end portion protruding substantially parallel to the end surface of the support portion 15 on the window 5 side, and is inclined slightly toward the window 5 side (for example, inclined at an angle of about 30 degrees toward the window 5 side). ) It protrudes obliquely downward by a predetermined length (for example, a length of about 15 mm).

  As shown in FIGS. 4 and 5, the hook portion 16 is substantially perpendicular to the flat contact portion 16 </ b> A that can contact the lower end surface 15 </ b> A of the support portion 15 and the edge portion on the window 5 side of the contact portion 16 </ b> A. An extending portion 16B extending downward by a predetermined length (for example, about 20 mm in length), and a recessed portion 16C extending from the lower end portion of the extending portion 16B to the indoor side in a U shape in a side view. And a tip portion 16D which is an end portion on the opposite side to the extending portion 16B of the concave portion 16C. Accordingly, the hook portion 16 is formed in a substantially C shape in a side view that opens to the indoor side.

  In addition, the hook portion 16 has a circular support shaft 18 with both ends supported by the lower end surface of the support portion 15 at the indoor side edge of the contact portion 16A, so that the hook portion 16 can be turned indoors. Is retained. The support shaft 18 supports the hook portion 16 so as to be rotatable about an axis 18 </ b> A intersecting with the winding direction of the sunshade 6. Further, the extending portion 16B has a guide groove 21 that is recessed downward from the upper end surface with a width dimension larger than the thickness of the leaf spring 17 and into which the protruding portion 17B of the leaf spring 17 is inserted over the entire length in the vertical direction. Is formed.

  As shown in FIGS. 4 and 6, the protrusion 17B of the leaf spring 17 is in contact with the side surface of the guide groove 21 on the window 5 side, and passes along the axis 18A passing through the center of the support shaft 18 and the axis 18A. The hook portion 16 is urged to rotate in a direction away from the surface 19 with reference to a virtual surface 19 including a straight line in the winding direction of the sunshade 6 that intersects the sunshade 6. Further, the rotation biasing direction of the leaf spring 17 is a direction in which the gap 20 between the tip end portion 16D of the hook portion 16 and the lower end surface 15A of the support portion 15 widens. That is, the leaf spring 17 urges the hook portion 16 to rotate in the direction toward the window 5. Further, when the sunshade 6 is stored in the winding storage device 7 and the locking member 8 is not locked to the locked member 13, the hook portion 16 has a contact portion 16 </ b> A below the support portion 15. Abutting on a restricting portion 15B formed on the end face 15A, the rotation is restricted, and the position is restricted to the initial position in a stable state.

Next, a method of pulling out the sunshade 6 and locking the locking member 8 to each locked member 13 will be described with reference to FIGS. 1, 2, 6 to 8. 6 to 8 are explanatory views for explaining a method of locking the locking member 8 to the locked member 13.
As shown in FIGS. 2, 6, and 7, first, the user holds the lever 11 of the locking member 8, and the upper end of the locking member 8 substantially reaches the upper edge of the window opening 3 </ b> A of the window frame 3. Upwardly (upward in FIG. 6), each locking hole 12 is opposed to the hook portion 16 of each locked member 13 from the indoor side.

  Then, as shown in FIG. 7, the user inserts the upper edge portion of each locking hole 12 into each hook portion 16 from the gap 20, and the recessed portion 16 </ b> C of each hook portion 16 in each locking hole 12. And release the lever 11. As a result, each locking hole 12 of the locking member 8 is opposed to the substantially central portion in the back side direction of the concave portion 16C of each hook portion 16 and is more than the support shaft 18 that rotatably supports each hook portion 16. Located on the window 5 side. Therefore, as shown in FIG. 8, each hook portion 16 biases the sunshade 6 in the winding direction (downward in FIG. 8, that is, the direction of the arrow 22) via the locking member 8. By the urging force 23 of the winding storage device 7, the sunshade 6 is urged to rotate in the winding direction. As a result, each hook portion 16 is a direction in which the gap 20 that passes when each locking hole 12 is locked to the concave portion 16C of the hook portion 16 is narrowed, and the direction toward the virtual surface 19 is approached. (In the direction of arrow 25 in FIG. 8).

  That is, each hook portion 16 extends from the initial position in a direction in which the gap 20 becomes narrow until the linear direction connecting the locking member 8 and the axis 18A of the support shaft 18 coincides with the winding direction of the sunshade 6. It is rotated. As a result, the concave portion 16C of each hook portion 16 is rotated inwardly about the support shaft 18 while moving in the insertion direction in each locking hole 12, and the side view of each hook portion 16 is substantially U. The inner peripheral part of each latching hole 12 is contact | abutted by the character-shaped bottom part. As shown in FIG. 8, the tip end portion of the protruding portion 17 </ b> B of each leaf spring 17 is inserted into the guide groove 21 of each hook portion 16.

  Further, the take-up and storage device 7 is arranged so that the take-up direction of the sunshade 6 is directly below the support shaft 18. In addition to the weight of the sunshade 6, the locking member 8, and the lever 11, the take-up and storage device 7 The urging force acts directly below the support shaft 18. Therefore, each hook portion 16 is in a state where the linear direction connecting the locking member 8 and the axis 18 </ b> A of the support shaft 18 matches the winding direction of the sunshade 6 against the rotational biasing force of each leaf spring 17. Until it becomes, it is rotated from the initial position to the indoor side (in the direction of arrow 25 in FIG. 8). Note that the upper edge of the window opening 3 </ b> A of the window frame 3 may have a function as the support portion 15.

  As a result, as shown in FIG. 1, the locking member 8 is locked to the window frame 3, and the sunshade 6 covers the window 5. Further, in each hook portion 16, the tip end portion 16 </ b> D of each concave portion 16 </ b> C rotates upward from the initial position to lock each locking hole 12. For this reason, even when the sunshade 6 is pressed in the indoor side direction or the window 5 side direction due to an unexpected external force such as the sunshade 6 being blown by the wind, the hook portion 16 swings following the external force. The use state of the sunshade 6 can be easily prevented from being released by an unexpected external force. Further, since the urging force of each leaf spring 17 is always transmitted to each locking hole 12 via the hook portion 16, the leaf spring 17 serves as a damper, and each hook portion 16 is swung when each hook portion 16 swings. Generation | occurrence | production of the noise which generate | occur | produces from the engagement location of the locking hole 12 and each recessed part 16C can be suppressed as much as possible.

  Next, a method for releasing the locking of the locking member 8 from each locked member 13 will be described with reference to FIGS. FIG. 9 is an explanatory view for explaining a method of releasing the locking of the locking member 8 to the locked member 13.

  As shown in FIG. 9, the user first holds the lever 11 of the locking member 8 and lifts it slightly upward (in the direction of arrow 26 in FIG. 9). The load on the hook portion 16 due to is eliminated. Thereby, each hook part 16 moves in each locking hole 12 by the urging force of the leaf spring 17 which is a rotation urging member, and can be rotated in the direction in which the gap 20 expands, that is, the window 5 side. .

  Therefore, each hook part 16 is along the guide groove 21 formed in the extension part 16B by the rotation biasing force by the protrusion part 17B of each leaf | plate spring 17 inserted in the guide groove 21 of the extension part 16B. Then, it is rotated around the support shaft 18 in the direction toward the window 5 (in the direction of arrow 27 in FIG. 9). And each hook part 16 is contact | abutted by the regulation part 15B formed in the lower end surface 15A of the support part 15 by contact | abutting part 16A, and rotation regulation is carried out, and the position regulation is carried out to the initial position in the stable state.

  Thereafter, when the user holds the lever 11 of the locking member 8 and moves it to the near side, the locking between the locking holes 12 and the hook portions 16 is released. Then, as shown in FIG. 6, when the user inserts the locking member 8 into the opening 9 </ b> A of the door trim 9, the locking member 8 is in the initial state where the sunshade 6 is wound around the winding storage device 7. Held in position.

  As described in detail above, in the sunshade device 1 according to the first embodiment, the user pulls the locking holes 12 of the locking member 8 from the indoor side in the state where the sunshade 6 is pulled out. It is made to oppose to the hook part 16. Then, the user inserts the upper edge portion of each locking hole 12 into the inside of each hook portion 16 from the gap 20, inserts the concave portion 16 </ b> C of each hook portion 16 into each locking hole 12, and moves the lever 11. Release your hand.

  As a result, each hook portion 16 is urged in the winding direction of the sunshade 6, so that each hook portion 16 is chambered around the support shaft 18 against the rotational urging force of the protruding portion 17 </ b> B of the leaf spring 17. It is turned inward. As a result, since each hook part 16 and each locking hole 12 move relative to each other, each locking hole 12 moves to the back side of each hook part 16, and the locking member 8 locks to each hook part 16. Is done. That is, each hook portion 16 is in a direction in which the gap 20 between the tip portion 16D and the lower end surface 15A of the support portion 15 is narrowed, and is rotated in a direction approaching the virtual surface 19 to be in a stable state. Each locking hole 12 is locked to each hook portion 16.

  As a result, by engaging each locking hole 12 of the locking member 8 with each hook portion 16, each hook portion 16 rotates each tip portion 16D upward from its initial position, The hole 12 is locked. For this reason, even when the sunshade 6 is pressed in the indoor side direction or the window 5 side direction due to an unexpected external force such as the sunshade 6 being blown by the wind, the hook portion 16 swings following the external force. The use state of the sunshade 6 can be easily prevented from being released by an unexpected external force. Further, since the urging force of each leaf spring 17 is always transmitted to each locking hole 12 via the hook portion 16, the leaf spring 17 serves as a damper, and each hook portion 16 is swung when each hook portion 16 swings. Generation | occurrence | production of the noise which generate | occur | produces from the engagement location of the locking hole 12 and each recessed part 16C can be suppressed as much as possible.

  Further, since it is not necessary to greatly extend the tip 16D of each hook portion 16 in the drawing direction of the sunshade 6, each locking hole 12 of the locking member 8 can be easily engaged with each hook portion 16. The sunshade 6 can be easily attached to the use state via the locking member 8. Further, when each hook portion 16 is rotated in the direction toward the window 5 by the protruding portion 17B of the leaf spring 17, the contact portion 16A contacts the restriction portion 15B formed on the lower end surface 15A of the support portion 15. It is contacted and is restricted from rotating, and is regulated to the initial position in a stable state. For this reason, each hook part 16 can be stably hold | maintained in an initial position by simple structure, and each locking hole 12 of the locking member 8 can be easily engaged with each hook part 16. FIG.

  Three or more pairs of the locking holes 12 and the locked members 13 may be provided.

That is, you may comprise so that the window frame 3 may function as the support part 41. FIG.

  As shown in FIGS. 13 to 15, the hook portion 42 has a flat plate-like contact portion 42A that can contact the restriction portion 41G provided at the indoor side edge of the inner ceiling portion 41A of the support portion 41, and The guide portion 42B extends from the edge of the contact portion 42A on the inner ceiling portion 41A side to the substantially right angle window 5 side and guides the locking portion 40 to the inside of the hook portion 42, and the restriction portion 41G of the contact portion 42A. On the other hand, a concave portion 42C extending from the lower end edge on the opposite side to the window 5 side in a substantially U shape in a side view, and a tip end portion 42E that is an end opposite to the contact portion 42A of the concave portion 42C, It is composed of The inner side surface of the concave portion 42C is formed in a substantially V shape in side view. Further, the distal end portion 42E on the window 5 side of the concave portion 42C is formed so as to be closer to the indoor side than the distal end portion of the guide portion 42B.

  The hook portion 42 has a circular support shaft 45 having a circular cross section supported at both end portions on both side surface portions 41B of the support portion 41 at the end edge portion on the inner ceiling portion 41A side of the contact portion 42A. It is held so that it can rotate. Further, the torsion coil spring 43 as the rotation urging member is wound so as to surround the outer peripheral portion of the support shaft 45, one end side 43 </ b> A is attached to the inner ceiling portion 41 </ b> A of the support portion 41, and the other end side 43 </ b> B is It is attached to the abutting portion 42A of the hook portion 42.

  Further, the torsion coil spring 43 urges the hook portion 42 to rotate away from the virtual surface 44 with reference to the virtual surface 44 extending from the support shaft 45 in the winding direction of the sunshade 6. Further, the torsion coil spring 43 rotates the hook portion 42 so that the gap 50 between the tip end portion 42E of the hook portion 42 and a guide portion 41E provided on the support portion 41 described later is expanded. Energized.

  That is, the hook portion 42 is urged by the torsion coil spring 43 to rotate in the indoor side direction (in the direction of arrow 46 in FIG. 14) about the support shaft 45. When the sunshade 6 is housed and the locking member 32 is not locked to the locked member 33, the hook portion 42 is rotated by the torsion coil spring 43, and the contact portion 42 </ b> A is supported by the support portion 41. The rotation of the inner ceiling 41A is restricted by contact with a restricting portion 41G provided at the indoor side edge, and the position is restricted to the initial position in a stable state.

  In addition, the support portion 41 has a curvature radius (for example, a curvature radius that is slightly longer by about 2 mm) than the length of the guide portion 42B with the back side wall portion 41C facing the guide portion 42B of the hook portion 42 as the center. Is formed in an arc shape in a side view. The indoor side edge 41D at the lower end of the rear side wall 41C is formed so as to substantially face the tip of the guide part 42B of the hook part 42 located at the initial position.

  Further, the width dimension of the indoor side edge 41D at the lower end of the rear side wall 41C and the guide portion 42B of the hook portion 42 and the locking portion 40 formed at the tip of the lever portion 35 are substantially the same, or A gap 50 having a slightly larger dimension (for example, a dimension larger by about 1 mm) is formed. Further, the support portion 41 is inclined obliquely downward from the indoor side edge portion 41D of the lower end portion of the back side wall portion 41C toward the window 5, and is formed on the distal end side of the lever portion 35 as will be described later. A guide portion 41E is formed in which the stop portion 40 abuts and is guided to the hook portion 42 side.

  Next, a method of pulling out the sunshade 6 and locking the locking member 32 to the locked member 33 will be described with reference to FIGS. 10, 11, and 15 to 19. 16 to 18 are explanatory views for explaining a method of locking the locking member 32 to the locked member 33. FIG. 19 is an enlarged view of a main part of FIG. 18 showing a state in which the hook portion 42 and the lever portion 35 are locked.

  As shown in FIGS. 11, 15, and 16, first, the user holds the knob 35 </ b> A provided on the lever portion 35 of the locking member 32, and sets the upper end portion of the drawer portion 34 to the peripheral portion of the window opening 3 </ b> A. Pull up until reaching almost (in the direction of arrow 47 in FIG. 16). Then, the user pulls up the pull-out portion 34 upward while bringing the locking portion 40 of the lever portion 35 into contact with the guide portion 41E of the support portion 41 of the locked member 33, and moves the locking portion 40 to the gap 50. The concave portion 42C of the hook portion 42 is inserted into the through hole 39 of the lever portion 35.

  Then, as shown in FIG. 17, the user moves the lever portion 35 toward the front side (in the direction of arrow 48 in FIG. 17), and the side of the through hole 39 side of the locking portion 40 of the lever portion 35. After contacting the inner peripheral surface of the substantially U-shaped concave portion 42 </ b> C, the hand is released from the lever portion 35. As a result, as shown in FIGS. 18 and 19, the lever portion 35 is urged by a biasing force 51 that biases the sunshade 6 in the winding direction (downward in FIG. 18) via the drawer portion 34. Rotating to the window 5 side (in the direction of arrow 52 in FIG. 18) around the portion that contacts the concave portion 42C of the hook portion 42, the state becomes substantially parallel to the sunshade 6.

  Further, the hook portion 42 is caused by a biasing force 51 for biasing the sunshade 6 in the winding direction, a weight of the drawer portion 34, a weight of the sunshade 6, and the like via a lever portion 35 locked to the concave portion 42C. Against the rotational biasing force of the torsion coil spring 43 toward the indoor side, the direction approaches the virtual surface 44 (see FIG. 15) from the initial position, and the clearance 50 rotates in the direction of narrowing. That is, the hook part 42 is rotated toward the window 5 (in the direction of arrow 52 in FIG. 18). As a result, the hook portion 42 is rotated in the direction toward the window 5 from the initial position where the abutting portion 42A abuts on the regulating portion 41G provided at the indoor side edge of the inner ceiling portion 41A of the support portion 41, The concave portion 42 </ b> C is rotated around the support shaft 45 so as to approach the guide portion 41 </ b> E side of the support portion 41.

  Then, the locking portion 40 of the lever portion 35 is locked to the concave portion 42C of the hook portion 42 in a state where the hook portion 42 and the lever portion 35 are arranged in a substantially straight line in the vertical direction. Further, as shown in FIG. 19, when the locking portion 40 of the lever portion 35 is locked to the concave portion 42C of the hook portion 42, the locking portion 40 formed in a substantially triangular cross section is locked The side edge portion of the portion 40 on the side of the through hole 39 is brought into contact with the inner peripheral surface of the concave portion 42 </ b> C formed in a substantially V shape in a side view by the urging force 51 in the winding direction of the sunshade 6.

  Further, the take-up storage device 7 is attached at a position separated from directly below the support shaft 45, and the take-up direction of the sunshade 6 is an oblique direction. Then, the concave portion 42 </ b> C and the locking portion 40 are rotated by the urging force of the winding storage device 7 so as to be substantially straight in the winding direction. Here, with the urging force in the winding direction, since the locking portion 40 is formed in a shape that does not rotate inside the concave portion 42C, the hook portion 42 is restricted from rotating. Accordingly, the concave portion 42C and the locking portion 40 are stabilized in a state where they are not perfectly aligned in the winding direction, and the locking portion 40 is locked to the concave portion 42C.

  As a result, as shown in FIG. 10, the drawer portion 34 is locked to the locked member 33 of the window frame 3 via the lever portion 35, and the sunshade 6 covers the window 5. Moreover, the hook part 42 rotates to the guide part 41E side of the support part 41, and the clearance gap 50 between the front-end | tip part 42E of the recessed part 42C and the guide part 41E becomes narrow. As a result, it is difficult for the locking portion 40 of the lever portion 35 to drop off from the hook portion 42, and the use state of the sunshade 6 is prevented from being released by an unexpected external force in the window 5 side direction and the sunshade 6 winding direction. it can.

  Next, a method for releasing the locking of the locking member 32 to the locked member 33 will be described with reference to FIGS. 20 to 22 and FIG. 20 to 22 are explanatory views for explaining a method of releasing the locking of the locking member 32 to the locked member 33. FIG.

  As shown in FIGS. 20 and 21, first, the user holds the knob 35 </ b> A of the lever portion 35 and rotates it in the indoor side direction (in the direction of arrow 53 in FIG. 20). Thereby, the front-end | tip part of the latching | locking part 40 contact | abuts to the indoor side edge part 41D of 41 A of inner side ceiling parts of the support part 41, the lever part 35 rotates from the contacted part as a starting point, and a latching | locking part 40 rides on the tip 42E of the concave portion 42C, and the engagement between the locking portion 40 and the hook portion 42 is released.

  Then, as shown in FIG. 22, when the user further turns the knob 35 </ b> A in the upward direction (in the direction of arrow 53 in FIG. 22), the locking portion 40 of the lever portion 35 is wound from the gap 50. Advance to the storage device 7 side. As a result, the hook portion 42 is rotated in the direction in which the gap 50 expands around the support shaft 45, that is, the indoor side direction (in the direction of arrow 54 in FIG. 20) by the rotation biasing force of the torsion coil spring 43. Is done. As a result, the position of the hook portion 42 is restricted to the initial position where the contact portion 42A is in contact with the restriction portion 41G of the support portion 41, and is supported by the support portion 41 in a stable state.

  Thereafter, the user pulls down the drawer portion 34 while bringing the locking portion 40 of the lever portion 35 into contact with the guide portion 41E of the support portion 41, so that the locking portion 40 and the hook portion 42 of the lever portion 35 are pulled down. Is released. Then, as shown in FIG. 15, when the user inserts the drawer portion 34 into the opening 9 </ b> A of the door trim 9, the locking member 32 is positioned in the initial state where the sunshade 6 is wound around the winding storage device 7. Retained.

  As described in detail above, in the sunshade device 31 according to the second embodiment, the user lifts the lever 35 with the knob 35 </ b> A of the lever 35 that is rotatably provided in the drawer 34, and moves the lever 35. The recessed portion 42 </ b> C of the hook portion 42 is inserted into the through hole 39. Then, the user moves the lever portion 35 to the near side and brings the side edge portion on the through hole 39 side of the locking portion 40 into contact with the inner peripheral surface of the concave portion 42C, and then moves the hand from the lever portion 35. Let go.

  As a result, the lever portion 35 is urged in the winding direction of the sunshade 6, is rotated toward the window 5 around the portion that contacts the concave portion 42 </ b> C of the hook portion 42, and is substantially parallel to the sunshade 6. It becomes a state. Further, the hook portion 42 is biased in the winding direction of the sunshade 6 via the lever portion 35 engaged with the concave portion 42C, and resists the rotational biasing force toward the indoor side by the torsion coil spring 43. Thus, the support shaft 45 is rotated from the initial position toward the window 5 side.

  Therefore, by engaging the locking portion 40 of the lever portion 35 with the hook portion 42 of the locked member 33, the lever portion 35 and the hook portion 42 are rotated to the window 5 side, respectively. The hook portion 42 and the through hole 39 move relative to each other so that the concave portion 42C is arranged in a substantially straight line in the vertical direction. As a result, the engaging portion 40 having a substantially triangular cross section formed on the distal end side of the through hole 39 of the lever portion 35 has a side edge on the through hole 39 side of the engaging portion 40, and a concave portion of the hook portion 42. The locking member 32 is locked to the locked member 33 by moving from the tip 42E side of 42C to the contact portion 42A side.

  Accordingly, by engaging the locking portion 40 of the lever portion 35 with the hook portion 42 of the locked member 33, the hook portion 42 rotates and moves the locking portion 40 to the back side of the concave portion 42C. And locked. For this reason, even when the sunshade 6 is pressed in the indoor side direction or the window 5 side direction by an unexpected external force such as the sunshade 6 being blown by the wind, the hook portion 42 swings following the external force. It is possible to easily prevent the sunshade 6 from being released from use.

  Further, since the urging force of the torsion coil spring 43 is constantly transmitted to the locking portion 40 via the hook portion 42, the torsion coil spring 43 serves as a damper, and when the hook portion 42 swings, the locking portion It is possible to suppress the generation of abnormal noise generated from the engagement portion between 40 and the concave portion 42C as much as possible. Moreover, since the hook part 42 is urged | biased in the direction which the clearance gap 50 expands, when latching the latching | locking part 40, it is easy to latch. Moreover, in the state which latched the latching | locking part 40, since the hook part 42 is rotated in the direction which narrows the clearance gap 50, and the latching | locking part 40 becomes the space | interval which cannot pass the clearance gap 50, it latches by unexpected external force. Can be further prevented from being released.

  In addition, since the knob 35 </ b> A that is a handle for performing the drawer and storage operation of the sunshade 6 and the locking portion 40 are provided in the same lever portion 35, the locking portion 40 can be easily locked to the hook portion 42. Further, since the hook portion 42 is provided with the guide portion 42B, even when the locking portion 40 is pulled out in the pulling direction when the locking portion 40 is inserted inside the hook portion 42, the guide portion 42B. By this, the locking portion 40 is guided into the hook portion 42, so that it is easy to lock. The guide portion 42B may be formed on the support portion 41.

  Further, since it is not necessary to greatly extend the tip end portion 42E of the concave portion 42C of the hook portion 42 in the drawing direction of the sunshade 6, the locking portion 40 of the lever portion 35 can be easily engaged with the hook portion 42. The sunshade 6 can be easily attached to the use state via the lever portion 35. Further, the hook portion 42 is regulated in position by the torsion coil spring 43 to the initial position when the abutting portion 42A abuts on the regulating portion 41G formed on the indoor side edge of the inner ceiling portion 41A of the support portion 41. The hook portion 42 can be stably held at the initial position with a simple configuration, and the locking portion 40 of the lever portion 35 can be easily engaged with the hook portion 42.

  Further, the user holds the knob 35 </ b> A of the lever portion 35 substantially horizontally, pulls out the sunshade 6, and easily locks the locking portion 40 formed by the through hole 39 at the distal end portion of the lever portion 35 to the hook portion 42. The sunshade 6 can be easily attached to the use state via the lever portion 35. Since the lever portion 35 rotates so as to be substantially parallel to the sunshade 6 when the locking portion 40 is locked to the hook portion 42, the lever portion 35 is mounted in a state where the sunshade 6 is in use. It can improve the appearance without being obstructive.

  Further, when the lever portion 35 is rotated in the direction in which the sunshade 6 is pulled out (in the direction of arrow 53 in FIG. 22), the lower surface of the locking portion 40 of the lever portion 35 is the concave portion of the hook portion 42. Ride on the window 5 side edge of the inner surface of 42C. For this reason, the user can cancel | release the use condition of the sunshade 6 easily by holding the knob 35A of the lever part 35 substantially horizontally.

  Next, the sunshade apparatus 61 which concerns on 3rd Embodiment is demonstrated based on FIG. 23 thru | or FIG. In the following description, the same reference numerals as those of the sunshade device 1 according to the first embodiment shown in FIGS. 1 to 9 are the same as or equivalent to those of the sunshade device 1 according to the first embodiment. It is shown.

The schematic configuration of the sunshade device 61 according to the third embodiment is substantially the same as that of the sunshade device 1 according to the first embodiment.
However, the sunshade device 61 according to the third embodiment is different in that a locking member 62 is provided instead of the locking member 8.

  First, a schematic configuration of the locking member 62 will be described with reference to FIGS. FIG. 23 is a front view showing a sunshade device 61 in which the sunshade 6 according to the third embodiment is locked in a use state. FIG. 24 is an enlarged view of the main part of the A1 part of FIG. 25 is a cross-sectional view taken along the line X3-X3 in FIG.

  As shown in FIGS. 23 to 25, a locking member 62 is attached to the end edge portion of the sunshade 6 over the entire width by sewing and coupling. The locking member 62 is formed in a storage bag body 63 that is sewn or welded in the shape of an elongated bag that is long in the width direction of the sunshade 6, and an elongated shaft shape or an elongated cylindrical shape that is stored in the storage bag body 63. And a drawing portion 65. In addition, one end in the longitudinal direction of the plate-like lever 66 is fixed to the central portion in the longitudinal direction of the drawer portion 65, and a predetermined amount is provided from the insertion hole (not shown) formed in the central portion in the longitudinal direction of the storage bag 63 to the indoor side. The length (for example, about 3 cm in length) protrudes.

  The lead-out portion 65 is formed of a metal such as aluminum or stainless steel or a resin such as ABS, and is arranged over the entire longitudinal width in the storage bag body 63 with the axial direction along the upper edge of the storage bag body 63. ing. Moreover, it is preferable that the drawer | drawing-out part 65 is formed in a substantially columnar shape, a substantially square pillar shape, or a substantially cylindrical shape and a substantially square cylinder shape.

  In the storage bag 63, a main body cloth made of a single thin cloth material having a length substantially equal to the full width of the drawer side edge of the sunshade 6 is folded in two in the width direction, and both ends in the longitudinal direction are sewn. Thus, it is formed into a shallow horizontally long bag shape. In addition, the body cloth has a rectangular shape centered on a fold-fold line at a portion facing each locked member 13 in the longitudinal direction, and a pair of cutout holes 68 having a width wider than the width of the hook portion 16. Is formed. Further, the main body cloth has an insertion hole (not shown) through which the plate-like lever 66 is inserted at a substantially central position in the longitudinal direction.

  Then, in a state in which the drawer portion 65 is stored in the storage bag body 63 formed in a shallow horizontally long bag shape, the drawer-side edge of the sunshade 6 has a predetermined length (for example, a length of about 1 cm.) By inserting and sewing or welding together three pieces, the end side edge of the sunshade 6 is sewn or welded in a state of being sandwiched by the storage bag body 63. Further, a plate-like lever 66 protrudes from the insertion hole (not shown) formed in the longitudinal center of the storage bag body 63 to the indoor side by a predetermined length.

  As a result, as shown in FIGS. 23 and 24, when the upper end of the locking member 62 is pulled up to reach the peripheral edge of the window opening 3A by holding the lever 66, the hook of each locked member 13 is secured. A pair of horizontally long rectangles in front view through which the recessed portion 16C of the hook portion 16 is inserted by the cutout holes 68 and the drawing portion 65 of the storage bag 63 that are folded in half at positions facing the portion 16. A stop hole 69 is formed.

  A method for locking the locking member 62 configured as described above to each locked member 13 will be described with reference to FIGS. 23 and 25. As shown in FIGS. 23 and 25, first, the user holds the lever 66 of the locking member 62 and moves the upper end of the locking member 62 upward until it substantially reaches the upper edge of the window opening 3 </ b> A of the window frame 3. (It is upward in FIG. 23). Then, the user inserts the drawing portion 65 that forms the upper side portion of each locking hole 69 into each hook portion 16 from the gap 20, and inserts the concave portion 16 </ b> C of each hook portion 16 into each locking hole 69. Then let go of the lever 66.

  As a result, the lead-out portion 65 that forms the upper side portion of each locking hole 69 of the locking member 62 faces the substantially central portion in the back side direction of the concave portion 16C of each hook portion 16 and rotates each hook portion 16. It is located closer to the window 5 than the support shaft 18 that supports it. Therefore, as shown in FIG. 25, each hook portion 16 urges the sunshade 6 in the winding direction (downward in FIG. 25, that is, the direction of arrow 71) via the locking member 62. The urging force 72 of the take-up storage device 7 is urged to rotate in the take-up direction of the sunshade 6. As a result, each hook portion 16 has a direction in which the gap 20 that passes when the drawer portion 65 that forms the upper side portion of each locking hole 69 is locked to the concave portion 16C of the hook portion 16 is narrowed, and , It is rotated in the direction approaching the virtual surface 19 (in the direction of arrow 73 in FIG. 25).

  That is, each hook portion 16 has a gap 20 from the initial position until the linear direction connecting the drawing portion 65 of the locking member 62 and the axis 18A of the support shaft 18 coincides with the winding direction of the sunshade 6. It is turned in the direction of narrowing. As a result, the concave portion 16C of each hook portion 16 is rotated inwardly about the support shaft 18 while moving in the insertion direction in each locking hole 69, and the side view of each hook portion 16 is substantially U. The drawer | drawing-out part 65 which forms the upper side part of each latching hole 69 is contact | abutted by the character-shaped bottom part. In addition, as shown in FIG. 25, the front-end | tip part of the protrusion part 17B of each leaf | plate spring 17 is inserted in the guide groove 21 of each hook part 16. As shown in FIG.

  Further, the take-up and storage device 7 is arranged so that the take-up direction of the sunshade 6 is directly below the support shaft 18. In addition to the weight of the sunshade 6, the locking member 62 and the lever 66, the take-up and storage device 7 The urging force acts directly below the support shaft 18. Therefore, each hook portion 16 is in a state where the linear direction connecting the locking member 62 and the axis 18 </ b> A of the support shaft 18 matches the winding direction of the sunshade 6 against the rotational biasing force of each leaf spring 17. Until it reaches the indoor position (in the direction of arrow 73 in FIG. 25) from the initial position.

  As a result, as shown in FIGS. 23 and 25, the locking member 62 is locked to the window frame 3, and the sunshade 6 covers the window 5. Further, in each hook portion 16, the tip end portion 16 </ b> D of each concave portion 16 </ b> C rotates upward from the initial position, and the drawer portion 65 that forms the upper side of each locking hole 69 is locked. For this reason, even when the sunshade 6 is pressed in the indoor side direction or the window 5 side direction due to an unexpected external force such as the sunshade 6 being blown by the wind, the hook portion 16 swings following the external force. The use state of the sunshade 6 can be easily prevented from being released by an unexpected external force.

  Further, since the urging force of each leaf spring 17 is always transmitted to the drawer portion 65 that forms the upper side of each locking hole 69 via the hook portion 16, the leaf spring 17 serves as a damper, and each hook portion It is possible to suppress as much as possible the generation of abnormal noise generated from the engagement portion between the drawing portion 65 that forms the upper side of each locking hole 69 and each concave portion 16C when the 16 swings.

  Next, a method for releasing the locking of the locking member 62 to each locked member 13 will be described. First, when the user holds the lever 66 of the locking member 62 and lifts it slightly upward, the load on the hook portion 16 due to the urging force or the like of the winding storage device 7 is eliminated. Thereby, each hook part 16 moves in each locking hole 69 by the urging force of the leaf spring 17 which is a rotation urging member, and can be rotated in the direction in which the gap 20 expands, that is, the window 5 side. .

  Therefore, each hook part 16 is along the guide groove 21 formed in the extension part 16B by the rotation biasing force by the protrusion part 17B of each leaf | plate spring 17 inserted in the guide groove 21 of the extension part 16B. Thus, it is rotated around the support shaft 18 in the window 5 side direction. And each hook part 16 is contact | abutted by the regulation part 15B formed in the lower end surface 15A of the support part 15 by contact | abutting part 16A, and rotation regulation is carried out, and the position regulation is carried out to the initial position in the stable state.

  Thereafter, when the user holds the lever 66 of the locking member 62 and moves it to the near side, the locking between the drawer portion 65 that forms the upper side of each locking hole 69 and each hook portion 16 is released. Then, when the user inserts the locking member 62 into the opening 9 </ b> A of the door trim 9, the locking member 62 is held at the initial position where the sunshade 6 is wound up by the winding storage device 7.

  As described above in detail, in the sunshade device 61 according to the third embodiment, the user pulls the locking holes 69 of the locking member 62 from the indoor side in the state where the sunshade 6 is pulled out. It is made to oppose to the hook part 16. Then, the user inserts the drawing portion 65 that forms the upper side portion of each locking hole 69 into each hook portion 16 from the gap 20, and inserts the concave portion 16 </ b> C of each hook portion 16 into each locking hole 69. Then let go of the lever 66.

  As a result, each hook portion 16 is urged in the winding direction of the sunshade 6, so that each hook portion 16 is chambered around the support shaft 18 against the rotational urging force of the protruding portion 17 </ b> B of the leaf spring 17. It is turned inward. As a result, each hook portion 16 and the leading portion 65 that forms the upper side portion of each locking hole 69 move relative to each other, so that the leading portion 65 that forms the upper side portion of each locking hole 69 moves to the back of each hook portion 16. Moving to the side, the locking member 62 is locked to each hook portion 16. That is, each hook portion 16 is in a direction in which the gap 20 between the tip portion 16D and the lower end surface 15A of the support portion 15 is narrowed, and is rotated in a direction approaching the virtual surface 19 to be in a stable state. A drawer portion 65 that forms the upper side portion of each locking hole 69 is locked to each hook portion 16.

  Thereby, by engaging each locking hole 69 of the locking member 62 with each hook portion 16, each hook portion 16 rotates each tip portion 16D upward from the initial position, so that each locking portion The drawer 65 that forms the upper side of the hole 69 is locked. For this reason, even when the sunshade 6 is pressed in the indoor side direction or the window 5 side direction due to an unexpected external force such as the sunshade 6 being blown by the wind, the hook portion 16 swings following the external force. The use state of the sunshade 6 can be easily prevented from being released by an unexpected external force. Further, since the urging force of each leaf spring 17 is always transmitted to the drawing portion 65 that forms the upper side portion of each locking hole 69 via the hook portion 16, the leaf spring 17 serves as a damper, and each hook It is possible to suppress as much as possible the generation of abnormal noise generated from the engagement portion between the drawing portion 65 that forms the upper side portion of each locking hole 69 and each concave portion 16C when the portion 16 swings.

  Further, since it is not necessary to greatly extend the tip end portion 16D of each hook portion 16 in the direction in which the sunshade 6 is pulled out, each locking hole 69 of the locking member 62 can be easily engaged with each hook portion 16. The sunshade 6 can be easily attached to the use state via the locking member 62. Further, when each hook portion 16 is rotated in the direction toward the window 5 by the protruding portion 17B of the leaf spring 17, the contact portion 16A contacts the restriction portion 15B formed on the lower end surface 15A of the support portion 15. It is contacted and is restricted from rotating, and is regulated to the initial position in a stable state. For this reason, each hook part 16 can be stably hold | maintained in an initial position by simple structure, and each locking hole 69 of the locking member 62 can be easily engaged with each hook part 16. FIG.

  Note that three or more pairs of the locking holes 69 and the locked members 13 may be provided. Thereby, since three or more pairs of the locking holes 69 and the locked members 13 are provided, it is possible to improve the holding force of the locking members 62 that lock the sunshade 6 in the use state. As a result, the strength requirement of each locked member 13 can be relaxed, so that further downsizing can be achieved and the appearance of the sunshade device 61 can be further improved.

  In addition, this invention is not limited to the said 1st Embodiment thru | or 3rd Embodiment, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention.
