  2. Description of the Related Art Conventionally, a vehicle-mounted electric sideshade device has been proposed for blocking sunlight from a door window into a vehicle cabin and preventing glare from sunlight (see, for example, Patent Document 1). In the side shade device described in Patent Document 1, a winding shaft that winds up the awning sheet, a drive unit for feeding the awning sheet to the door window side, and the like are disposed in the internal door liner. The front and rear window edges of the door window are provided with guide rails that are each covered with an internal trim and extend in the vertical direction. Both ends of the drawer rod connected to the free end of the awning sheet are connected to the guide rails. Guided and movable up and down. The pull-out rod is configured to be guided on the guide rail by a flexible thrust member driven by a drive unit.

  With such a configuration, in the side shade device described in Patent Literature 1, the thrust member can be sent out by electrically driving the drive unit, and the draw rod can be moved up and down. Thereby, the door window is covered with the sunshade sheet, and sunlight inserted into the vehicle interior from the door window can be blocked to prevent glare.

JP 2003-182358 A (page 4-7, FIG. 1-6)

  However, since the side shade device of Patent Document 1 is configured to draw out the awning sheet from the lower side to the upper side, it cannot serve as a visor (shade) and blocks sunlight from the upper part of the door window. It was necessary to feed out the awning seat to a position above the door window. At this time, naturally, the lower part of the door window is covered with the awning sheet, so that the visibility to the outside through the door window cannot be secured satisfactorily.

  Moreover, the side shade apparatus of patent document 1 covers a door window in a rectangular shape. However, the door window is not usually rectangular, but has a trapezoidal shape, a parallelogram shape, and the like, and the side includes not only a straight line but also a curved line. For this reason, in the side shade apparatus of patent document 1, it divided | segmented into the part covered in a rectangular shape among the window frames of a door window, and the part other than that, and provided the awning sheet | seat separately, respectively. For this reason, the configuration of the apparatus is complicated.

  In view of the above problems, an object of the present invention is to provide a side shade device that has a simple configuration and can cover the entire area of a non-rectangular door window.

  According to the present invention, the object is to provide a sheet covering an opening surrounded by a window frame of a vehicle door, a roll shade part to which a base end part of the sheet is attached and winds up the sheet, and a free end of the sheet A side shade device comprising: an unfolding means for unfolding the sheet by pulling out the side; and the unfolding means includes a guide rail disposed along an edge of the opening, and the guide A slider guided along the rail, a driving means for moving the slider along the guide rail, and moves along the guide rail as the slider moves, and supports the free edge of the seat This can be solved by providing an expandable / contractible expansion / contraction member and expansion / contraction means for expanding / contracting the expansion / contraction member in conjunction with the unfolding and storing operation of the sheet.

  As described above, the side shade device according to the present invention is configured such that the sheet that covers the opening of the window frame is drawn out from the roll shade portion and spread when the slider moves along the guide rail. The free end of the sheet is supported by an expandable / contractible expansion / contraction member, and the expansion / contraction member is configured to be expanded / contracted by the expansion / contraction means in conjunction with the expansion / contraction operation of the sheet. Therefore, even when the width of the opening is not constant, the free end side of the sheet is prevented from being bent or the like due to expansion and contraction of the expansion / contraction member when the sheet is unfolded and stored, and is held in a predetermined shape. Thus, the opening can be reliably shielded.

  The opening may be formed wider on the developing side than on the sheet storage side, and the sheet may be formed to be extendable and extended in the width direction in accordance with a developing operation. it can. In this way, even if the opening is formed wider on the development side than on the sheet storage side, if the sheet is formed to be stretchable, the opening can be expanded by expanding the sheet in the width direction during development. The entire region in the width direction can be covered. At that time, if the sheet is stretched and the central portion of the free end side of the sheet is pulled toward the storage side to be in a curved state, the entire area of the opening cannot be covered. Since the end side is held in a predetermined shape by the elastic member, it is possible to prevent the central portion of the free end side from being bent toward the storage side.

  Moreover, the said sheet | seat can be set as the structure by which the insertion part which can insert the said expansion-contraction member along the free end side is formed. In this way, if the insertion portion is formed along the free end side of the sheet, and the elastic member is inserted into the insertion portion, the free end side is supported and the free end side is predetermined even if the sheet expands and contracts in the width direction. Can be held in the shape of.

  Further, when the expansion / contraction member has a hollow cylindrical shade guide and a slide shaft that moves forward / backward in the shade guide, the length of the expansion / contraction member as a whole is obtained by moving the slide shaft forward / backward from the shade guide. Can be expanded and contracted.

  The expansion / contraction means has a first linear member having one end fixed to one end of the guide rail and the other end fixed to the slide shaft; one end fixed to the other end of the guide rail; A second linear member having an end fixed to the slide shaft; and a first guide member and a second guide member which are provided on the slider and guide the first linear member and the second linear member. The first linear member is routed from one end side of the guide rail to the slide shaft through the inside of the shade guide via the first guide member and the other end side of the shade guide, The second linear member is routed from the other end side of the guide rail to the slide shaft through the second guide member and to the slide shaft. With the movement of the riders, can be configured to the slide shaft moves forward and backward relative to the shade guide.

  With such a simple configuration, in the present invention, when the slider and the expansion / contraction means move along the guide rail, the slide shaft can be moved back and forth with respect to the shade guide by the moving distance. That is, since one end of the first linear member and the second linear member is fixed to one end side of the guide rail and the other end is fixed to the slide shaft, when the slider and the expansion / contraction member move, the slide shaft It is pulled by the first linear member and the second linear member and moves along the shade guide. Thereby, the elastic member can be extended and contracted in conjunction with the movement of the slider.

  The expansion / contraction means includes a third linear member having both ends fixed to the slide shaft, a first guide member and a second guide member which are provided on the slider and guide the third linear member, and the guide A third guide member and a fourth guide member, which are provided on one end side and the other end side of the rail, respectively, for guiding the third linear member, and regulation means for regulating the movement of the third linear member, One end of the third linear member is fixed to the slide shaft, and is routed outside through the inside of the shade guide and through one end side of the shade guide, and the first guide member and the third guide A second guide member, a fourth guide member, and a second guide member. The other end of the shade guide is fixed to the slide shaft. When the movement of the third linear member is not restricted, the slide shaft is restricted from moving back and forth with respect to the shade guide, and when the movement of the third linear member is restricted by the restriction means The slide shaft can move forward and backward with respect to the shade guide as the slider moves.

  With such a simple configuration, in the present invention, the third linear member is rotated by the third guide member and the fourth guide member in a state where the third linear member is not regulated by the regulating means. The shaft and the shade guide move while maintaining their relative positions, and the elastic members are held at the same length. On the other hand, in a state where the third linear member is regulated by the regulating means, the slider and the elastic member move, whereby the slide shaft is pulled by the third linear member and moves along the shade guide. Thereby, the elastic member can be extended and contracted in conjunction with the movement of the slider. As described above, in the present invention, the expansion / contraction member can be expanded / contracted in conjunction with the movement of the slider, but the expansion / contraction member can be prevented from expanding / contracting depending on whether or not the restriction means is restricted. Thereby, even if the shape of the edge part of an opening part is not linear but more complicated shape, it becomes possible to expand and contract an expansion-contraction member corresponding to this shape.

The restricting means includes a drive unit that moves the third linear member. When the drive unit stops, the movement of the third linear member is regulated. By moving the third linear member, the slide shaft can be moved back and forth with respect to the shade guide.
If the third linear member can be moved by the drive unit in this way, the expansion / contraction member can be expanded / contracted in conjunction with the movement of the slider, and the expansion / contraction member can be moved regardless of the slider movement by the operation of the drive unit. Since it can be expanded and contracted, it becomes possible to perform finer adjustment of the length of the expandable member.

  According to the present invention, the free end side of the seat is supported by an extendable and contractible member, and the stretchable member can be extended and contracted in conjunction with the extending operation of the seat, so that the door window is not rectangular. However, when the sheet is stretched, the free end of the sheet can be held in a predetermined shape, and the entire area of the opening can be reliably shielded.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The members, arrangements, and the like described below are not intended to limit the present invention and can be variously modified within the scope of the gist of the present invention.

FIG. 14 is an electrical configuration diagram of FIG. 15 and 16 are explanatory views of the restricting means.

An embodiment in which a side shade device S (hereinafter referred to as “device S”) of the present invention is applied to a front side door 1 (hereinafter referred to as “door 1”) of a vehicle will be described.
FIG. 1 is an explanatory view of the right door 1 as viewed from the inside of the vehicle, partially cut away. The state in which the sheet 21 of the apparatus S is fed to a midway position between the storage position and the unfolded position is shown.
The door 1 is configured with a door trim 4 attached to the inside of the door panel 2. A window frame 3 is formed on the upper side of the door panel 2, and a trim member 5 is attached to the vehicle inside of the window frame 3. The trim member 5 is attached to the vehicle inner side along the front frame 3a, the upper frame 3b, and the rear frame 3c of the window frame 3. The trim member 5 and the door trim 4 may be integrally formed.

The front frame 3a and the rear frame 3c are frames arranged in the vertical direction extending upward from the door panel 2 main body. And the window glass 6 is arrange | positioned so that the opening part 2a formed with this window frame 3 may be plugged up. The window glass 6 can be moved up and down so as to close the opening 2a by a driving device (not shown).
The opening 2a of the window frame 3 has a substantially trapezoidal shape, and the upper side is narrower than the lower side. In the window frame 3 of this example, the front frame 3a is formed so as to rise from the main body side of the door panel 2 with an inclination, and the rear frame 3c is formed to rise in a substantially vertical direction. The connecting portion between the front frame 3a and the upper frame 3b has a rounded shape with a predetermined curvature.

The apparatus S of this example is disposed on the door 1 as described above, and includes a driving unit 10 as a driving unit, a roll shade mechanism unit 20, a guide unit 30, and a control unit 50. It is configured. The drive part 10 and the guide part 30 of this example are equivalent to the expansion | deployment means of this invention.
The drive unit 10 is disposed between the door trim 4 and the door panel 2. The drive unit 10 of this example includes an electric motor 11 and a speed reduction mechanism portion 12, and a cylindrical reel 13 for winding a wire 14 as a transmission member is attached to the output side of the speed reduction mechanism portion 12. ing.

  Further, as shown in FIG. 2, the drive unit 10 is integrally provided with a rotational position detection device 15. The rotational position detection device 15 outputs a pulse signal (rotational speed signal) synchronized with the rotation of the output shaft to which the reel 13 is connected to the control unit 50. The rotational position detection device 15 of this example is configured to detect a magnetic change of a magnet that rotates together with an output shaft by a plurality of Hall elements. The control unit 50 detects the position of the sheet 21 or the slider 32 by counting the pulse signals from the rotational position detection device 15. In this example, the rotational position detection device 15 and the control unit 50 constitute position detection means.

  In this example, a device using a Hall element is used for the rotational position detection device 15. However, the present invention is not limited to this, and an encoder or the like may be employed as long as the movement position of the seat 21 can be detected. . Further, the position of the sheet 21 may be directly detected by known means such as a limit switch.

The control unit 50 is configured by a microcomputer or the like, and supplies a drive voltage to the drive unit 10 based on an operation signal from the operation switch 16. At that time, the control unit 50 controls the position of the sheet 21 based on the pulse signal from the rotational position detection device 15.
The operation switch 16 of this example has operation positions such as lowering and raising, and when the occupant operates the operation switch 16 to the raised position or the lowered position, an ascending command signal or a descending command signal is output. Upon receiving this signal, the control unit 50 applies a drive voltage in the forward rotation direction or the reverse rotation direction to the electric motor 11. As a result, the reel 13 rotates forward and backward according to the switch operation, and the device S operates.

As shown in FIG. 1, the roll shade mechanism unit 20 of this example includes a roll shade unit 22 and a roll shade holding unit 26 that is disposed at both ends of the roll shade unit 22 and supports the rotation of the roll shade unit 22. And a sheet 21 having a base end attached to the roll shade portion 22 and covering the opening 2 a of the window frame 3.
The sheet 21 of this example has a predetermined transmittance, and is formed of a sheet material (cloth) that can be expanded and contracted in the width direction. As the stretchable sheet material, a stretchable sheet material is used that is woven. Further, even if the filamentous wire material itself is not so stretchable, it can be formed to have stretchability by weaving. Moreover, you may use the planar elastic member which can be expanded-contracted not only in the width direction but in the expansion | extension / storage direction.

In this example, as shown in FIGS. 6 and 7, on the side of the seat 21 along the guide rail 31 disposed on the rear frame 3 c, a narrow band-like engaged portion 21 a is disposed. . The engaged portion 21 a is formed to be thicker than the thickness of the sheet 21 and is configured to be supported while being in sliding contact with the guide portion 30.
In other words, in this example, the opening side (vehicle lower side) is trapezoidal in which the width in the vehicle front-rear direction of the opening 2a is larger than the storage side (vehicle upper side) of the seat 21, and the seat 21 is expanded. Then, the sheet 21 is extended in the width direction of the window glass 6. Since the roll shade portion 22 for winding the sheet 21 is disposed along the front frame 3a and the upper frame 3b, the vehicle front side and the upper side of the seat 21 are supported by the roll shade portion 22.

Accordingly, as the seat 21 is unfolded, a contracting force is applied to the seat 21 in the width direction. Therefore, the contracting force causes the seat 21 to move between the rear side of the vehicle 21 and the rear frame 3c or the guide rail 31. In the seat 21 of this example, the engaged portion 21 a is attached to the side of the rear side of the vehicle and is engaged with the guide portion 30 so that no gap is generated. This can improve the appearance. The engaged portion 21 a is formed of a flexible resin material and can be wound around the roll shade portion 22.
Further, in this example, the engaged portion 21a that is separate from the sheet 21 is disposed on the side of the sheet 21, but if the side can be supported, for example, the end of the sheet 21 is folded and formed thick. It is good also considering a site | part as an engaged part.

As shown in FIG. 3, an insertion portion (insertion portion) 21c along the free end side is formed on the free end side of the sheet 21 by folding the end portion and sewing it with the sewing portion 21b. The sewing portion 21b is mountain-stitched so as not to prevent the sheet 21 from extending in the width direction.
A long elastic member 34 is inserted into the insertion portion 21 c, and the free end side of the sheet 21 is supported by the elastic member 34. The telescopic member 34 of this example includes a shade guide 35 that is a hollow cylindrical member, and a slide shaft 36 that can move forward and backward within the shade guide 35.

  In the seat 21 of this example, at least the rear end portion of the vehicle among the free ends is indirectly or directly supported by the slider 32 of the guide portion 30 described later. In this example, the end portion of the shade guide 35 is fixed to the slider 32, and the seat 21 is indirectly attached to the slider 32 by attaching the insertion portion 21 c to the shade guide 35. Note that the end of the sheet 21 may be directly attached to the slider 32.

  The roll shade portion 22 is a columnar component member, and is curved and disposed along the front frame 3 a and the upper frame 3 b of the window frame 3. The roll shade portion 22 is disposed between the window frame 3 and the trim member 5 covering the window frame 3 so that there is no trouble during traveling. A slit 5a is formed in the trim member 5 toward the inside of the opening 2a. The sheet 21 is configured to be drawn out from the roll shade portion 22 through the slit 5a and cover the opening 2a.

4 and 5, the curved roll shade portion 22 is disposed on the center shaft 23 arranged in a curved state along the window frame 3, and on one end side of the center shaft 23 (the vehicle front side in this example). An urging means 24 is provided, and a cylindrical rotating rod 25 connected to the urging means 24 and rotatably disposed so as to cover the center shaft 23 is provided.
A bracket 26a is disposed on the front side of the upper frame 3b. The bracket 26a is located near the center of the roll shade portion 22 in the length direction, and supports the roll shade portion 22 while slidingly contacting the outer periphery of the roll shade portion 22 when the roll shade portion 22 is rotated. 22 prevents blurring.
Both ends of the center shaft 23 are fixed to the roll shade holding portion 26, and it is only necessary to maintain a curved shape with both ends attached to the roll shade holding portion 26. It may be a shaped member, or may be curved when it is formed of a flexible material and attached to the roll shade holder 26.

The urging means 24 includes a coil spring 24a having a center shaft 23 inserted therein and one end fixed to the center shaft 23, a cylindrical spring holder 24b rotatably disposed on the center shaft 23, and a spring holder 24b. A cylindrical member 24c that is connected and covers the coil spring 24a is provided. The other end of the coil spring 24a is fixed to one spring holder 24b.
The biasing means 24 is disposed in a state where the coil spring 24a is twisted so that a rotational force (biasing force) is applied in a direction in which the coil 21 is wound.

The rotating rod 25 is configured by connecting a center rod 25a, a joint 25b, and a side rod 25c. The side rod 25c, the joint 25b, and the center rod 25a are formed of synthetic resin, for example, and are rigid bodies such as rubber that do not have flexibility or stretchability.
The side rod 25c is disposed at the end of the center shaft 23, and the end surface on one end side in the longitudinal direction is substantially annular. In addition, on the end surface on the other end side of the side rod 25c, engagement protrusions protruding in the axial direction and having a predetermined angular width are formed at two positions facing each other at approximately 180 degrees.
Engaging protrusions similar to the engaging protrusions of the side rod 25c are formed in the axial direction at both ends in the longitudinal direction of the center rod 25a. However, the engaging protrusions formed at both ends of the center rod 25a are formed so that the phase is shifted by approximately 90 degrees in the circumferential direction.

The joint 25b connects the side rod 25c and the center rod 25a or the center rods 25a in the axial direction. For this reason, two engaging recesses that engage with the engaging protrusions are formed at both ends in the longitudinal direction of the joint 25b. The engaging recess is formed so as to cut out a part of the axial end surface of the joint 25b.
Similarly to the center rod 25a, the engaging recess is formed at a position shifted by approximately 90 degrees in the circumferential direction at both ends. The engagement protrusions of the side rod 25c and the center rod 25a are fitted in the engagement recesses of the joint 25b, and these are connected to each other.

  Since it is configured in this way, the rotating rod 25 including the side rod 25c, the joint 25b, and the center rod 25a can be connected in the axial direction while the center shaft 23 is inserted. When these parts are sub-assembled to assemble the roll shade portion 22, the side rod 25c, the joint 25b, and the center rod 25a are assembled with a space margin (play). By this play, the side rod 25c or the center rod 25a connected to both sides of the joint 25b can be bent approximately every 90 degrees with the joint 25b as a joint portion. In this example, the engagement protrusions and the engagement recesses are simply connected with each other. However, the connection between the engagement protrusions and the engagement recesses is possible by using a pin or the like so that it can be easily bent. Also good.

  Further, the circumferential width of the engaging protrusion is formed substantially the same as the circumferential width of the engaging recess, and when the rotating rod 25 rotates around the center shaft 23 as the rotation axis, the side rod 25c and the joint 25b are formed. The center rod 25a can transmit the rotational force with almost no deviation in the rotational direction. Therefore, even if the side rod 25c, the joint 25b, and the center rod 25a are connected in the axial direction, they can rotate as a whole while being curved as a whole. As described above, the roll shade portion 22 of this example has flexibility as a whole.

  Since the roll shade portion 22 is configured in this way, the roll shade portion 22 that is sub-assembled is curved along the front frame 3a and the upper frame 3b of the window frame 3, and both end portions are roll shade holding portions 26. Can be attached and fixed. At this time, the center shaft 23 is fixed to the roll shade holding portion 26, and the rotating rod 25 disposed around the center shaft 23 can rotate while following the shape of the curved center shaft 23. That is, even when the rotating rod 25 rotates about the center shaft 23 as a rotation axis, the curved shape of the center shaft 23 is maintained, and the roll shade portion 22 is maintained along the curved shape of the window frame 3. .

Moreover, in this example, although the window frame 3 is curving, the curvature changes with parts. That is, the connecting portion between the front frame 3a and the upper frame 3b has the largest curvature. In order to easily follow such curvature, the center rod 25a of this example uses three types having different axial lengths. That is, a center rod 25a having a short axial length is adopted for a portion with a large curvature, and a center rod 25a having a long axial length is adopted for a portion with a small curvature.
In this example, by configuring in this way, the roll shade portion 22 can be easily rotated following the curve, and the number of parts is reduced to reduce the number of assembling steps.

  With such a configuration, in the roll shade portion 22 of the present example, when the sheet 21 is rotated in the forward direction in which the sheet 21 is expanded, the coil spring 24a is further twisted to increase the rotational force in the direction in which the sheet 21 is accommodated. Sometimes the tension is applied to the seat 21 and the storage is smooth during the storage.

  As shown in FIG. 1, the guide portion 30 of this example includes a guide rail 31 that is disposed between the rear frame 3 c and the trim member 5 and extends from the vicinity of the upper end of the rear frame 3 c to the vicinity of the lower end thereof, and the guide rail 31. A slider 32 that is guided inward and movable along the length direction of the guide rail 31, an engagement portion 33 that is juxtaposed and fixed to the guide rail 31, an elastic member 34 that is connected to the slider 32, and this expansion and contraction The member 34 is configured to include expansion / contraction means 40 and the like for driving the member 34 to expand and contract in conjunction with the unfolding and storing operation of the sheet 21.

As shown in FIGS. 6 and 7, the guide rail 31 has a sliding groove 31 a that holds the slider 32 in a slidable manner.
The slider 32 of this example includes a slide portion 32a having a substantially circular cross section that is slidably held in the slide groove 31a, and a fixed portion 32b that supports the slide portion 32a. The vehicle rear end portion of the shade guide 35 of the elastic member 34 is connected to the fixed portion 32b.
The engaging portion 33 of this example is provided in parallel from the upper end to the lower end of the guide rail 31, and an engaging groove 33a having a substantially rectangular cross section is formed in parallel with the sliding groove 31a. The engaged portion 21a provided on the sheet 21 is engaged with the engagement groove 33a, and the side of the sheet 21 is pulled toward the opening 2a so that a gap into which sunlight is inserted is not formed. ing.

Further, one end of the wire 14 is connected and fixed to the lower portion of the slide portion 32 a of the slider 32. The wire 14 passes through the sliding groove 31a and is guided to the drive unit 10 via the pulley 17 disposed under the guide rail 31 (see FIG. 1). The other end of the wire 14 is attached to the reel 13 of the driving unit 10, and the driving unit 10 can wind the wire 14.
In this example, the wire 14 is guided to the drive unit 10 via the pulley 17. However, the present invention is not limited to this, and an introduction medium member other than the pulley 17 is arranged to guide the wire 14 to the drive unit 10. May be. As another introduction mediating member, for example, a member having a pipe or a groove can be used. In this case, the wire 14 may be slid in the pipe or in the groove by passing the wire 14 into the pipe or placing the wire 14 in the groove. In addition, a member having a groove may be arranged at a position where the direction of the wire 14 is changed to change the direction of the wire 14.

  As described above, the elastic member 34 of this example includes the cylindrical shade guide 35 and the slide shaft 36 movably inserted into the shade guide 35. The shade guide 35 is set to a length substantially the same as the length of the upper frame 3 b, and the slide shaft 36 enters the shade guide 35 in the stored state in which the sheet 21 is wound around the roll shade portion 22. When the sheet 21 is pulled out from the roll shade portion 22, the slide shaft 36 of the telescopic member 34 is pulled out from the shade guide 35. At this time, the slide shaft 36 moves downward together with the shade guide 35 while its front end (vehicle front end side) portion is positioned slightly in front of the front frame 3a. Thus, the expansion / contraction member 34 expands and contracts as the sheet 21 is unfolded and accommodated, and supports the free end side of the sheet 21 in the horizontal direction and linearly. Thereby, it is possible to prevent the vicinity of the center of the free end side of the sheet 21 from being contracted toward the roll shade portion 22 by the contraction force and the free end side to have a curved shape.

As shown in FIG. 8, the expansion / contraction means 40 of this example includes a pulley (first guide member) 41 and a pulley (second guide member) 42 attached to the upper part and the center part of the slider 32, respectively, and one end being a guide rail. 31 is fixed in the vicinity of the upper end, and is routed into the shade guide 35 via the pulley 41 and the front end side (vehicle front side) of the shade guide 35, and the other end is the base end portion (vehicle rear side) of the slide shaft 36. A wire (first linear member) 43 fixed to the guide rail 31 and one end fixed to the vicinity of the lower end of the guide rail 31, routed into the shade guide 35 via the pulley 42, and the other end fixed to the slide shaft 36. The wire (second linear member) 44 is provided.
In this example, the pulleys 41 and 42 are provided on the slider 32. However, as long as the wires 43 and 44 can be guided, a resin material or a metal material having good slidability may be used instead of the pulleys. Further, in this example, the wire 43 and the wire 44 are separate, but the present invention is not limited to this, and one wire may be connected.

In this example, a wire fixing portion 45 is fixed near the upper end of the guide rail 31 and a wire fixing portion 46 is fixed near the lower end, supporting one end of each of the wires 43 and 44 and holding the wires 43 and 44 at an appropriate tension. is doing. In order to hold the wires 43 and 44 at a more appropriate tension, a tension device for preventing sagging may be provided.
An insertion hole 35 a for allowing the wire 43 to pass therethrough is formed at the tip of the shade guide 35. The wire 43 passes from the wire fixing portion 45 through the pulley 41, passes through the insertion portion 21c of the seat 21 and is led to the insertion hole 35a, is turned back by the insertion hole 35a, passes through the shade guide 35, and is proximal to the slide shaft 36. It is fixed to the part.

  In addition, an insertion hole 35 b for allowing the wire 44 to pass therethrough is formed at the proximal end portion of the shade guide 35. The wire 44 is guided upward along the guide rail 31 from the wire fixing portion 46, enters the shade guide 35 through the insertion hole 35 b through the pulley 42, and is fixed to the proximal end portion of the slide shaft 36. In this example, the wires 43 and 44 are fixed to substantially the same portion of the base end portion of the slide shaft 36.

The operation of the expansion / contraction means 40 will be described based on FIG.
9A shows a state in which the slider 32 is positioned at the upper end of the guide rail 31, FIG. 9B shows a state in which the slider 32 has moved downward from the upper end, and FIG. 9C shows that the slider 32 has a lower end. The state located in the section is shown.
In FIG. 9A, the slide shaft 36 is completely in the shade guide 35 up to the tip.

  When the slider 32 moves downward as shown in FIG. 9B from this state, the upper end of the wire 43 is fixed, so that the lower end of the wire 43 is pulled out from the shade guide 35 through the insertion hole 35a. As a result, the slide shaft 36 is pulled out of the shade guide 35 by the same length as the moving distance of the slider 32. Further, the lower end of the wire 44 is fixed, and the upper end is pulled forward of the vehicle by the distance traveled by the slide shaft 36. Since this distance is the same distance as the slider 32 is lowered, the tension of the wires 43 and 44 is kept the same as before the movement.

When the slider 32 moves to the lower end as shown in FIG. 9C, the connecting portion between the slide shaft 36 and the wire 43 moves to the vicinity of the insertion hole 35a.
Thus, when the slider 32 is lowered, the slide shaft 36 is pulled out from the shade guide 35 by the lowered distance, and the telescopic member 34 is extended in conjunction with the movement of the slider 32.

  On the other hand, when the slider 32 rises from the state shown in FIG. 9C to the state shown in FIG. 9A, the lower end of the wire 44 is fixed. Is pulled out from the shade guide 35. As a result, the slide shaft 36 is pulled toward the base end side of the shade guide 35. Further, the upper end of the wire 43 is fixed, and the lower end is drawn toward the base end side of the shade guide 35 by the amount that the slide shaft 36 is drawn. Since this distance is the same distance as the slider 32 is lifted, the tension of the wires 43 and 44 is kept the same as before the movement.

Next, operation | movement of the apparatus S of this example is demonstrated. As described above, when the occupant operates the operation switch 16 to the lowered position in the state (stored state) of FIG. 10A, a lowering command signal is output to the control unit 50. The control unit 50 receives the lowering command signal and supplies a drive voltage for forward rotation driving to the drive unit 10, and the drive unit 10 rotates in the forward direction to rotate the reel 13 forward. As a result, the wire 14 is wound around the reel 13. As the wire 14 is wound up, the slider 32 moves downward along the guide rail 31 along with this.
As the slider 32 moves downward, the sheet 21 is pulled downward by the elastic member 34 connected to the slider 32. Accordingly, the roll shade portion 22 rotates forward, and the sheet 21 passes through the slit 5a. It goes out. At this time, a rotational force is applied to the roll shade portion 22 in the direction of winding the sheet 21 by the coil spring 24a. Accordingly, the sheet 21 is pulled out from the roll shade portion 22 in a state where an appropriate tension is applied.

Since the sheet 21 is particularly stretchable in the width direction, as shown in FIG. 10B, the slider 32 moves downward, and the width of the opening 2a to be covered by the sheet 21 increases. Even so, the sheet 21 can expand in the width direction following this width. Thereby, in the apparatus S of this example, it is possible to cover substantially the entire region of the window frame 3 having the trapezoidal opening 2a.
At this time, the seat 21 is contracted in the width direction and is also contracted toward the upper side of the vehicle. Therefore, if the free end side is not supported by the expansion and contraction member 34, the dashed line in FIG. As indicated by a, the free end is bent upward by the upward contractive force.
However, in the apparatus S of the present example, since the free end side of the sheet 21 is linearly supported by the expansion and contraction member 34, the free end side of the sheet 21 can be held linearly even when unfolded. Thereby, it is possible to cover the substantially whole area of the opening 2a.

The occupant can lower the seat 21 to a desired position by holding the operation switch 16 in the lowered position. When the operation switch 16 is returned to the neutral position, the drive of the drive unit 10 is stopped and the drive unit 10 is provided. The seat 21 can be held at the position by the self-holding function (for example, a clutch).
The control unit 50 stops supplying the drive voltage to the drive unit 10 when the rotational position detection device 15 detects that the sheet 21 has reached the deployed position where the sheet 21 is completely shielded from the opening 2a.

Further, when the occupant wants to raise the seat 21, the occupant operates the operation switch 16 to the raised position. As a result, an ascending command signal is output to the control unit 50. The control unit 50 receives the ascending command signal and supplies a driving voltage for reverse rotation driving to the driving unit 10, and the driving unit 10 rotates in the reverse direction to reversely rotate the reel 13. As a result, the wire 14 is fed out from the reel 13. As the wire 14 is fed out, the sheet 21 is wound by the rotational force in the winding direction by the coil spring 24a applied to the roll shade portion 22 and the slider 32 is raised. When the slider 32 moves to the upper end position, the seat 21 can be accommodated in the trim member 5. When the rotation position detection device 15 detects that the sheet 21 has been completely stored, the control unit 50 stops supplying the drive voltage to the drive unit 10.
Note that limit switches may be provided at the upper end position and the lower end position where the slider 32 is movable, and the voltage supply to the drive unit 10 may be stopped when the limit switch is activated.

As described above, the device S of the present example can cover substantially the entire area of the opening 2a of the window frame 3, and thereby can function as a shade. Thereby, the insertion of sunlight into the vehicle interior can be prevented and the temperature rise in the vehicle interior can be suppressed. Moreover, although the example which applied the apparatus S to the front right door of the vehicle was shown in the present Example, not only this but the apparatus S may be applied to all of a front window, a side door window, a rear window, etc. . In this way, the temperature rise in the passenger compartment can be further suppressed.
Further, if the material of the sheet 21 is changed variously and set to an appropriate light transmittance, the apparatus S can also function as a smoke film.

Further, in the apparatus S of the present example, since the roll shade portion 22 is disposed along the front frame 3a and the upper frame 3b of the window frame 3, the sheet 21 can cover the opening 2a from the upper side. The function as a visor can be provided. Thus, the apparatus S of this example can perform both functions as a visor and a shade.
The occupant can also use the device S of this example as an insect repellent by lowering the seat 21 with the window glass 6 lowered and the window opened. Further, by lowering the seat 21 to a predetermined position, it is possible to prevent wind from hitting the upper body such as the head during traveling.
Further, in the apparatus S of this example, the drive unit 10, the roll shade mechanism unit 20, and the guide unit 30 that are constituent members are disposed between the door panel 2 and the door trim 4 or between the door panel 2 and the trim member 5. The apparatus S is suitable because it does not get in the way when not in use. Furthermore, since the device S is disposed not on the vehicle side but on the door side, it does not interfere with the operation of the curtain shield airbag and can ensure safety.

Other embodiments of the present invention are shown below. In addition, the same code | symbol is attached | subjected to the same component as the said embodiment, and the overlapping description is abbreviate | omitted.
In the above-described embodiment, the free end side of the sheet 21 is folded and sewn, and the insertion portion 21c into which the elastic member 34 can be inserted is configured. However, the configuration is not limited to this, and the insertion portion 21c may be configured as shown in FIG.
In the example of FIG. 11, a plurality of ring members 21 d are arranged at the free end of the seat 21. The ring member 21d has a ring 21e into which the shade guide 35 can be inserted, and an attachment portion 21f for fixing the ring 21e to the seat 21, and when the seat 21 extends in the width direction, the shade guide 21d. 35 and the slide shaft 36 are movable in the ring 21e. The free end portion of the seat 21 can also be supported by the plurality of ring members 21d.

In the above embodiment, the expansion / contraction means 40 is configured such that the slide shaft 36 always moves forward and backward with respect to the shade guide 35 in conjunction with the vertical movement of the slider 32. However, the present invention is not limited to this. As in the example shown in FIG. 13, the forward / backward movement of the slide shaft 36 may be controllable.
The expansion / contraction means 140 of this example includes a pulley (first guide member) 41 and a pulley (second guide member) 42 attached to the upper and center portions of the slider 32, and the vicinity of the upper end portion and the lower end portion of the guide rail 31, respectively. The pulley (third guide member) 145 and the pulley (fourth guide member) 146 respectively provided on the front end of the shade guide 35 are fixed to the slide shaft 36 from the inside of the shade guide 35. A wire (third wire) that is routed to the outside via the pulley 41, the pulley 145, the pulley 146, and the pulley 42 and led to the inside of the shade guide 35 and the other end fixed to the slide shaft 36. 143) and a regulating means 160 that regulates the movement of the wire 143.
One end of the wire 143 is fixed to the proximal end portion of the slide shaft 36, passes through the inside of the shade guide 35, and is drawn out from the insertion hole 35 a.

As shown in FIG. 13, the restricting means 160 of this example includes pads 164 a and 164 b that sandwich and lock the wire 143, a rack 163 coupled to the pad 164 a, a pinion 162 that meshes with the rack 163, and a pinion 162. An electric motor 161 that rotates is provided.
As shown in FIG. 14, the electric motor 161 is connected to the control unit 50, and is displaced into a locked state and an unlocked state by a drive signal from the control unit 50. That is, in the unlocked state, when the electric motor 161 is actuated by the drive signal from the control unit 50 and the pinion 162 rotates forward, the rack 163 moves to the left. As a result, the pad 164a is pressed against the pad 164b, the pinched wire 143 is locked, and the vertical movement is restricted.
Further, when the electric motor 161 is actuated by the drive signal from the control unit 50 and the pinion 162 rotates reversely in the locked state, the rack 163 moves to the right. As a result, the pad 164a moves to the right, and the wire 143 is released to be unlocked.

  As shown in FIG. 12A, in the expansion / contraction means 140 of this example, when the wire 143 is in an unlocked state where it is not restricted by the restriction means 160, when the slider 32 moves up and down, the shade moves along with this movement. The wire 143 rotates the pulleys 145 and 146 while the relative position between the guide 35 and the slide shaft 36 is maintained. Thereby, although the slider 32 moves up and down, the expansion and contraction of the expansion and contraction member 34 is restricted.

  On the other hand, as shown in FIG. 12B, in the telescopic means 140 of this example, when the wire 143 is in the locked state regulated by the regulating means 160, the slider 32 moves up and down as in the above embodiment. With this movement, the slide shaft 36 moves forward and backward with respect to the shade guide 35. That is, when the slider 32 is lowered, the slide shaft 36 is pulled out from the shade guide 35, and when the slider 32 is raised, the slide shaft 36 is drawn toward the base end portion of the shade guide 35.

The control unit 50 of the present example stores an amount of pulling out the slide shaft 36 from the shade guide 35 according to the vertical position of the slider 32. Then, the control unit 50 regulates the movement of the wire 143 and the regulation by the regulating unit 160 according to the vertical position of the slider 32 calculated based on the pulse signal from the rotational position detection device 15 and adjusts the amount of withdrawal.
Thereby, even when the front frame 3a is curved rather than linear, the slide shaft 36 is pulled out from the shade guide 35 in accordance with the curvature, and the free end of the seat 21 is held linearly. It becomes possible.

  Further, in the present example, a detection unit that detects the amount of the slide shaft 36 that is pulled out may be provided, and the control unit 50 may control the regulation unit 160 based on a detection signal from the detection unit. For example, a rotation detection unit that detects the rotation amount of the pulleys 145 and 146 that is proportional to the pull-out amount of the slide shaft 36 can be used as the detection unit.

In the example of FIG. 12, the electric motor 161 is used as the restricting means 160, and the control unit 50 restricts the movement of the wire 143 by controlling the operation of the electric motor 161. It is also possible to adopt a configuration in which no electric motor is used.
That is, the restricting means 260 of FIG. 15A fixes the spherical stoppers 261 and 263 to the wire 143, and the wire guide 262 having passage holes 262a and 264a that allow the wire 143 to pass but not the stoppers 261 and 263 to pass. H.264 is provided. The wire guides 262 and 264 are fixed to the guide rail 31.

In this example, the wire guide 262 is disposed above the stopper 261, and the wire guide 264 is disposed below the stopper 263. Therefore, when the slider 32 moves downward, the wire 143 moves upward. When the slider 32 moves downward by a predetermined distance, the stopper 261 is restrained by the wire guide 262, and the wire 143 moves further upward. Is regulated. When the slider 32 further moves downward in a state where the wire 143 is constrained, the slide shaft 36 is pulled out from the shade guide 35 and the telescopic member 34 is expanded.
On the other hand, when the slider 32 moves upward, the wire 143 moves downward. When the slider 32 moves upward by a predetermined distance, the stopper 263 is restrained by the wire guide 264, and the wire 143 moves further downward. Is regulated. When the slider 32 further moves upward in a state where the wire 143 is restrained, the slide shaft 36 is drawn to the proximal end side of the shade guide 35, and the telescopic member 34 is reduced.

  With such a simple configuration, in this example, in a predetermined range where the stoppers 261 and 263 are not restrained by the wire guides 262 and 264, the length of the elastic member 34 is maintained at the same length, and the slider 32 exceeds the predetermined range. When the slider 32 is moved upward, the expandable member 34 can be contracted. When the slider 32 moves downward beyond a predetermined range, the expandable member 34 can be expanded.

Further, in FIG. 15A, the restricting means 260 is configured by the spherical stoppers 261 and 263 and the wire guides 262 and 264, but may be configured as illustrated in FIG.
In the example of FIG. 15B, the stoppers 261 and 263 are cup-shaped instead of spherical. The wire guides 262 and 264 are provided with hooks 262b and 264b that engage with the stoppers 261 and 263, respectively.

In the example of FIG. 12, the restricting means 160 is configured to clamp and fix the wire 143 between the pads 164a and 164b. However, the configuration is not limited to this, and a configuration as illustrated in FIG.
In the example of FIG. 16, the regulating means 360 includes a pulley 362 around which a wire 143 is wound, and an electric motor 361 as a drive unit that rotationally drives the pulley 362.

In the restricting means 360 of this example, when the electric motor 361 is stopped, the wire 143 is restricted from moving up and down. Thereby, the slide shaft 36 can be moved forward and backward relative to the shade guide 35 in conjunction with the vertical movement of the slider 32.
On the other hand, when the electric motor 361 is operated, the wire 143 is moved upward or downward according to the rotation direction, so that the slide shaft 36 can be moved forward and backward with respect to the shade guide 35 regardless of the operation state of the slider 32. . At this time, if the pulley 362 is rotated by the electric motor 361 in conjunction with the movement of the slider 32, the slide shaft 36 can be held stationary with respect to the shade guide 35.

For example, when the electric motor 361 rotates forward while the slider 32 is stationary, the wire 143 moves upward. Since one end of the wire 143 is connected to the proximal end portion of the slide shaft 36 via the pulley 146, when the wire 143 moves upward, the slide shaft 36 is pulled toward the proximal end portion side of the shade guide 35 and this direction Move to.
On the other hand, when the electric motor 361 rotates in the reverse direction, the wire 143 moves downward. Since the other end of the wire 143 is connected to the proximal end portion of the slide shaft 36 via the pulley 145, when the wire 143 moves downward, the slide shaft 36 is pulled toward the distal end side of the shade guide 35 and this direction Move to.

As described above, in this example, by moving the wire 143 up and down by the operation of the electric motor 361, the extendable member 34 can be expanded and contracted without the slider 32 moving up and down.
Therefore, in this example, the control unit 50 detects the withdrawal amount using the detection signal from the detection unit that detects the withdrawal amount of the slide shaft 36, and the current withdrawal amount is set with respect to the vertical position of the slider 32. Thus, the length of the expansion / contraction member 34 can be adjusted more finely so as to match the amount of withdrawal.

Further, in the above embodiment, the driving means for moving the slider 32 along the guide rail 31 is configured such that the end of the wire 14 is connected to the slider 32 and the wire 14 is wound around the reel 13 by the operation of the electric motor 11. However, as long as the slider 32 can be moved along the guide rail 31, it is not limited to the configuration of the above embodiment.
For example, the slider 32 may be moved up and down along the guide rail 31 in conjunction with the movement of the rack by rotating the pinion with an electric motor and moving the rack meshing with the pinion up and down.
In addition, the spiral cable may be sent out by the operation of the electric motor to move the slider 32 up and down along the guide rail 31.
