Description

  The present invention relates to a sunshade device, and more particularly to a sunshade device that covers an opening of a vehicle and blocks sunlight.

2. Description of the Related Art Conventionally, vehicle-mounted electric sunshade devices have been proposed for blocking sunlight from a door window into a passenger compartment and preventing glare from sunlight (see, for example, Patent Documents 1 to 3). The door window provided on the upper part of the door of the vehicle is not normally rectangular, but is, for example, trapezoidal or parallelogram corresponding to the shape of the door, and the side is not limited to a straight line but includes a curved line. In Patent Documents 1 to 3, the entire non-rectangular door window is covered with a blind sheet.
A sunshade device (a blind device for a side window) described in Patent Literature 1 is attached to a door window divided into two by a vertical frame garnish. In Patent Document 1, the front portion of the substantially rectangular door window on the front side of the vehicle can be covered with a blind sheet drawn upward from a winding shaft disposed on the lower frame side. In addition, the rear portion of the non-rectangular door window on the vehicle rear side can be covered with a blind sheet that is pulled out sideways from a winding shaft disposed in a garnish that partitions two windows.

  The sunshade device (window shade device for window) described in Patent Document 2 is attached to a door window divided into two by a vertical frame-shaped central bridge, as in Patent Document 1. In Patent Document 2, a winding shaft that winds up a awning sheet and an end of a drawer rod connected to the free end of the awning sheet are placed inside the inner door liner below the front part of the substantially rectangular door window on the front side of the vehicle. A drive unit or the like for moving up and down along the side edge portion of the window front portion is disposed, whereby the door window front portion can be covered with an awning sheet drawn upward. The rear part of the door window on the rear side of the vehicle has an R-shaped window frame and is non-rectangular, but this window extends from the winding shaft arranged vertically along the central bridge to the side. Can be covered with a sunshade sheet pulled out.

  The sunshade device described in Patent Document 3 is attached to a substantially trapezoidal door window whose lower side is longer than the upper side, and a blind sheet is wound around a roll shade part attached to a window frame surrounding the upper side and the oblique side. The blind sheet is drawn downward from the roll shade portion. The blind sheet of Patent Document 3 is made of a stretchable material, and the entire width of the door window can be covered by extending the blind sheet in the width direction as the free end of the blind sheet is lowered from above. .

Japanese Patent Laying-Open No. 2005-96529 (page 4-6, FIG. 1-2) JP 2003-182358 A (page 4-7, FIG. 1-6) JP 2006-51925 A (pages 16-19, FIGS. 20-27)

However, since the sunshade devices of Patent Documents 1 and 2 are configured to feed out the blind sheet (the awning sheet) from the lower side to the upper side or from the side, the sunshade device cannot serve as a visor (eave). In order to block sunlight from the upper part of the door window, it was necessary to extend the blind sheet (a awning sheet) so as to cover the door window. At this time, naturally, the lower part of the door window is covered with a blind sheet (an awning sheet), so that the visibility from the outside through the door window is ensured while blocking sunlight from the upper part of the door window. I couldn't.
Further, in the sunshade devices of Patent Documents 1 and 2, the drawing direction of the blind sheet (the awning sheet) is different between the door window front part and the door window rear part divided into two. Accordingly, there is a problem in that it does not look good in the state of being stretched halfway, and is unsatisfactory in appearance because the moving directions are not aligned during the stretching operation.

Further, the sunshade device of Patent Document 3 covers a non-rectangular window by extending the width of the blind sheet using a stretchable sheet material, but in order to keep the blind sheet in an expanded state, An engaged portion was provided at the side end portion and engaged with the engaging portion in the side frame of the door window. Therefore, the side edge of the blind sheet needs to be processed, and the configuration becomes complicated, and the wound sheet does not become compact.
In addition, since the blind sheet is used by expanding and contracting, the sheet material is likely to be deteriorated. In particular, when the blind sheet is left in a stretched state for a long period of time, the blind sheet is not stretched and contracted, so that it cannot be smoothly wound. There was a problem.
Further, in the stretched state, the free end side portion of the blind sheet is in an extended state, while the roll shade portion side portion is not extended, resulting in unevenness in the appearance of the blind sheet and poor appearance. It was.

  The present invention has been made in view of the above circumstances, and an object thereof is to cover a non-rectangular door window whose bottom side is wider than the top side with a blind sheet from above to below. An object of the present invention is to provide a sunshade device that can cover the entire area of the door window with good appearance without expanding and contracting the blind seat.

  According to the sunshade device of the present invention, the problem is that a substantially straight upper frame, an inclined frame extending obliquely downward from one end side of the upper frame, and a connecting portion between the upper frame and the inclined frame A sunshade device that is attached to a window frame that includes a support column extending downward from the first shield unit and shields the substantially rectangular first opening and the non-rectangular second opening defined by the support column. A first sheet and a second sheet provided corresponding to each of the first opening and the second opening, and a roll shade part capable of winding and storing the first sheet and the second sheet. A first extension mechanism part and a second extension mechanism part that can be extended by pulling out the first sheet and the second sheet from the roll shade part, respectively, and the roll shade part extends along the upper frame. On the straight line and the inclined frame The first sheet is wound around the linear portion, and the second sheet is wound around the inclined portion. The stretching mechanism unit extends or stores the first sheet by moving the free end side of the first sheet toward the upper side or the lower side of the first opening, and the second stretching mechanism unit , Operated in conjunction with the position of the free end portion side of the first sheet, the free end portion side of the second sheet toward the upper end side or the lower end side of the support column on the free end portion side of the first sheet This is solved by moving to a position corresponding to the position and winding the surplus portion of the second sheet pulled out from the inclined portion to the column side.

Thus, in the sunshade device of the present invention, in the window frame in which the non-rectangular opening having the inclined frame extending obliquely downward from one end side of the upper frame is divided into two adjacent openings by the support column, These openings are shielded by pulling out different blind sheets (first sheet and second sheet) from the upper frame side and the inclined frame side, respectively. At this time, since the first sheet and the second sheet are interlocked, the two openings can be shielded synchronously by the two blind sheets. Therefore, the appearance of the operating sunshade device can be improved.
In addition, since the second sheet drawn out from the inclined frame is drawn obliquely downward, the side end on the column side protrudes from the region of the second opening and overlaps with the column and the first sheet to become an excess part. In the present invention, by winding up the surplus portion, the entire area of the opening can be covered with the first sheet and the second sheet, and the drawn-out second sheet protrudes from the area of the second opening or sags. There is nothing to do. Moreover, blind sheets do not overlap each other. Therefore, it is possible to cover the opening with a good appearance. Moreover, it is not necessary to expand / contract the second sheet so that an excessive portion does not occur. Therefore, the durability and appearance of the blind sheet can be improved.

  The lower end side of the first sheet and the lower end side of the second sheet are moved in a state of being substantially parallel and substantially straight with respect to the lower parting line of the first opening and the second opening. Thus, it is preferable that the first sheet and the second sheet are pulled out. As described above, when the plurality of sheets are pulled out, their lower end sides are arranged in a substantially straight line, so that the appearance can be further improved.

The second sheet includes an inclined side extending along the inclined part, a vertical extending side extending substantially perpendicular to a tangent at an end of the inclined part on the straight line side, and a lower part of the second opening. It is preferable to have a shape that is substantially parallel to the parting line and surrounded by a horizontal side that connects the inclined side and the vertical extending side.
In this way, the horizontal side is made substantially parallel to the parting line at the bottom of the second opening, and at the same time, the vertical extension side is made to extend substantially perpendicular to the tangent line at the end of the inclined portion on the straight line side. The second sheet can be stretched and stored without twisting or the like while keeping the lower end side of the second sheet parallel to the second opening lower parting line while winding the portion on the support column side.

Further, the second sheet is wound while being aligned and wound so that the side end side on the support column side is located at the end of the inclined portion on the linear portion side, and is pulled out from the inclined portion. It is preferable that the width of the part pulled out along with is increased.
If comprised in this way, the position of the lower end part by the side of the inclination frame of the 2nd sheet | seat pulled out will move gradually below along the inclination of an inclination frame. Therefore, the lower end side of the second sheet can be lowered as the second sheet is drawn obliquely downward. Therefore, the lower end side of the second sheet can be lowered in synchronization with the lower end side of the first sheet, and when the plurality of sheets are pulled out, the lower end sides can be aligned in a straight line.

The second extension mechanism has a substantially cylindrical guide shaft disposed along the support column, and a moving member guided along the guide shaft. Side edges of the two sheets on the free end side are attached, and the moving member is interlocked with a position on the free end side of the first sheet along a spiral groove formed on the outer peripheral surface of the guide shaft. It is preferable that the support column is moved between the upper end and the lower end of the support column and rotated around the central axis of the guide shaft in accordance with the inclination of the spiral groove.
If the second extension mechanism is configured in this way, the side edge on the free end side of the second sheet spirals along the outer peripheral surface of the guide shaft, so that while pulling the second sheet obliquely downward, A part can be wound around the outer periphery of the guide shaft and the moving member. Therefore, the excess part of the second sheet can be wound on the support column side.

The moving member is formed of a cylindrical member having a substantially cylindrical through-hole, and a guide projection having a shape corresponding to the spiral groove is formed on the inner peripheral surface of the cylindrical member. The second sheet is attached to the outer peripheral surface of the member, and the guide shaft is inserted through the through-hole, and the guide projection is fitted into the spiral groove and guided in the spiral groove. It is preferable.
Thus, if a guide protrusion is formed in the internal peripheral surface of a cylindrical member, and a guide shaft is penetrated to this, a cylindrical member can be moved up and down while rotating along a spiral groove.

The first extension mechanism includes a pair of guide rails disposed along a side edge of the first opening, a slider guided along the guide rail, and the slider as the guide rail. First guide means for moving along the guide shaft, and one of the guide rails is disposed along the guide shaft on the support column, and the moving member is moved in conjunction with the slider. Such a configuration is preferable.
Further, it is preferable that the moving member is rotatably connected to the slider guided along the guide rail disposed on the support column by a connecting member.
If comprised in this way, since a moving member and a slider are arrange | positioned adjacently, these can be moved easily interlockingly. Further, by connecting the moving member to the slider so as to be rotatable, the moving member and the slider can be easily interlocked, and the free end portions of the second sheet and the first sheet can be interlocked and moved.

In addition, a holding portion is formed on the outer surface of the moving member, and one end side of the connecting member is joined to the slider, and a held portion that can be held by the holding portion is formed on the other end side. The member can be configured to be rotatably connected to the connecting member by holding the held portion so as to be relatively movable with respect to the holding portion.
Further, the holding part is composed of an annular groove formed on the outer peripheral surface of the moving member, the held part is composed of a substantially U-shaped part formed so as to be fitted on the annular groove, and the moving member is Since the substantially U-shaped portion is slidably held in the annular groove, it can be configured to be rotatably connected to the connecting member.
With such a configuration, the moving member and the slider arranged adjacent to each other can be rotatably connected, and the free end portions of the second sheet and the first sheet can be moved in conjunction with each other.

The second extension mechanism is disposed at an acute angle with respect to a lower parting line of the second opening along the support column, and a substantially cylindrical guide shaft whose lower end is located below the parting line. And a moving member guided along the guide shaft, and a side end side of the second sheet on the free end side is attached to the moving member, and the moving member has an outer periphery of the guide shaft. Along the spiral groove formed on the surface, in conjunction with the position on the free end side of the first sheet, it is moved between the upper end of the column and the lower end located below the parting line, The second sheet is rotated around the central axis of the guide shaft according to the inclination of the spiral groove, and the second sheet is spirally wound around the guide shaft as the moving member descends. The side edge on the free end side of the Ri line with is lowered to a position below the, the lower end side of the second sheet, it is preferable to be lowered to the vicinity of the parting line remains substantially parallel to the parting line.
When the guide shaft is inclined at an acute angle with respect to the lower parting line of the second opening, the side edge on the free end side of the second sheet spirally wound around the guide shaft is the second sheet. Since the lower end side of the guide shaft is positioned below the parting line, the guide member is positioned below the parting line, and the moving member can be lowered below the parting line. The lower end side can be lowered to the vicinity of the parting line while being substantially parallel to the opening parting parting line. As a result, when a plurality of sheets are pulled out, their lower end sides can be aligned in a substantially straight line, and the appearance can be improved.

The first extension mechanism includes a pair of guide rails disposed along a side edge of the first opening, a slider guided along the guide rail, and the slider along the guide rail. And a straight line connecting the pair of sliders has an angle with respect to a lower parting line of the first opening, and is on the free end side of the first sheet Are connected to a pair of sliders, and a long free end holding member bent at a position close to one of the sliders is fixed at least when the first sheet is stretched. At the time of extension, the portion on the other slider side from the bent position of the free end holding member is held at a height different from that of the one slider and substantially parallel to the parting line. During storage of the first sheet, it is preferable that the free end portion holding member is stored in the storage portion of the roller shade portion.
Since it is configured in this way, the straight line connecting the pair of sliders is not parallel to the lower parting line of the first opening, and the free end of the first sheet is the lower parting line of the first opening as it is. Even if it becomes slanted with respect to the other side, by providing the free end holding member, the other slider side portion that occupies most of the free end portion of the first sheet is held substantially parallel to the parting line. However, it can be stretched and stored, the unnatural appearance can be eliminated, and the first sheet can be stretched without distortion. Further, even when the free end portion of the first sheet reaches the lowermost end of the slider, the other slider side portion that occupies most of the free end portion of the first sheet is substantially parallel to the parting line. Therefore, by lowering the portion on the other slider side of the free end portion of the first sheet to a position overlapping the lower parting line, the entire first opening can be shielded without generating a gap. Furthermore, since the free end holding member is stored in the storage portion of the roll shade portion when the first sheet is stored, the appearance when stored can be maintained.

The second extension mechanism includes second driving means for moving the moving member along the guide shaft, and determines a current position on the free end side of the first sheet and a current position of the moving member. It is preferable to comprise a detecting means for detecting and a control means for controlling the driving of the first driving means and the second driving means in synchronism based on a detection signal from the detecting means. In this way, if the first sheet and the second sheet are driven by separate driving means, and the drive control is performed so as to synchronize the first sheet and the second sheet, the first and second stretching mechanism parts are physically connected. Even if it does not do, the 1st sheet and the 2nd sheet can be pulled out synchronously.
In addition, it is preferable that the first extension mechanism portion and the second extension mechanism portion are disposed between the window frame and a trim member disposed on the vehicle interior side of the window frame. By doing so, the first and second extension mechanism portions are not visually recognized from the passenger compartment side, and the appearance is improved.

In the roll shade portion, it is preferable that at least the inclined portion has flexibility. In this way, even if the window frame has a curved portion, the roll shade portion can be arranged according to the frame shape.
Further, the first sheet and the second sheet are formed so as not to expand and contract. As described above, in the present invention, even a non-stretchable sheet material can be extended and stored.
The sunshade device of the present invention is applied to a front window, a rear window, or a side window of a vehicle.

According to the sunshade device of the present invention, in a window frame in which a non-rectangular opening whose width of the bottom side is wider than that of the upper side is divided into two adjacent openings by a support, the upper frame side and the inclined frame side When a separate blind sheet is pulled out from each other and shielded, the excess part of the blind sheet (second sheet) pulled out from the inclined frame is wound up on the support column side, so that the entire opening portion is not expanded and contracted. The area can be nicely covered. Further, the appearance can be further improved by pulling out the lower edge sides of the plurality of blind sheets so as to be aligned in a straight line.
Further, when the moving member moves while being guided by the spiral groove formed on the outer peripheral surface of the guide shaft disposed on the support column, the side edge on the free end side of the second sheet attached to the moving member is Since it is configured to spirally move along the outer peripheral surface of the guide shaft, a part of the second sheet can be wound around the outer periphery of the guide shaft and the moving member while being drawn obliquely downward.
Further, the guide shaft and the guide rail are disposed adjacent to the support column, and the moving member is pivotally connected to the slider so that the moving member is interlocked with the slider based on the driving force transmitted to the slider. Can be moved. Therefore, the second sheet and the free end side of the first sheet can be moved in conjunction with each other based on the driving force of one driving source.

  As shown in FIG. 5, the coil spring 22b is a coil spring slightly shorter than the center shaft 22a. The center shaft 22a, the coil spring 22b, and the spring holder 22c constitute a torsion coil spring as a whole. The coil spring 22b is provided around the outer periphery of the center shaft 22a. As shown in FIG. 5, one end of the coil spring 22b is reverse to the flange portion of the spring holder 22c that is rotatably provided around one end of the center shaft 22a. It is fixed to the end on the side and is rotatable with respect to the center shaft 22a. The other end of the coil spring 22b is directly fixed to the other end side of the center shaft 22a that does not include the spring holder 22c.

The rotating rod 22d is a pair of side rods 23 constituting both ends of the rotating rod 22d, a plurality of center rods 25 connected between the pair of side rods 23, joints connecting the side rods 23 and the center rod 25. 24 is connected.
The side rod 23 is made of a synthetic resin and is formed of a rigid hollow substantially cylindrical body. Both end surfaces of the side rod 23 are planes perpendicular to the length direction, and the end surface on the side to which the center rod 25 is connected is positioned at two positions facing each other at approximately 180 degrees as shown in FIG. An engagement protrusion 23a that protrudes in the direction and has a predetermined angular width is formed. The inner periphery of the side rod 23 in the vicinity of the end surface on the end side of the center shaft 22a has a cross section in which a part of the arc is linearly cut out, and the part in which the cross section is cut out linearly is the spring holder 22c. It is formed as a plane portion that engages with the notched plane.

The center rod 25 is made of a synthetic resin and is formed of a rigid hollow substantially cylindrical body. Both end surfaces of the side rod 23 are planes perpendicular to the length direction, and both end surfaces of the center rod 25 protrude in the axial direction at two positions facing each other at approximately 180 degrees as shown in FIG. Engagement protrusions 25a having the angular width are formed. The engagement protrusions 25a on both end faces of the center rod 25 are formed with a phase shift of approximately 90 degrees in the circumferential direction.
The joint 24 is made of a synthetic resin and is formed of a rigid hollow substantially cylindrical body. As shown in FIG. 6, engagement recesses 24 a that are notched in a U shape in the axial direction are formed at two ends on both end faces of the joint 24. It is configured to be engageable with the protrusion 25a. The engaging recesses 24a on both end faces are formed with a phase shift of approximately 90 degrees in the circumferential direction.
The engagement protrusions 23 a and 25 a of the side rod 23 and the center rod 25 are loosely fitted in the engagement recesses 24 a of the joint 24, and the side rod 23 and the center rod 25 or the center rods 25 are connected in the axial direction by the joint 24. A rotating rod 22d is configured.

When assembling the roll shade portions 22A and 22B by sub-assembling the side rod 23, the joint 24, and the center rod 25, the side rod 23, the joint 24, and the center rod 25 are provided with a space (play) between them. Attached. By this play, the side rod 23 or the center rod 25 connected to both sides of the joint 24 can be bent approximately 90 degrees with the joint 24 as a joint.
In the present embodiment, the side rod 23, the joint 24, and the center rod 25 are connected by engaging the engaging protrusions 23a and 25a and the engaging recess 24a. It may be configured to be easily bent in a joint shape.

  Further, the circumferential widths of the engagement protrusions 23a and 25a are formed to be substantially the same as the circumferential width of the engagement recess 24a, and when the rotation rod 22d rotates around the center shaft 22a as a rotation axis, The rod 23, the joint 24, and the center rod 25 can transmit the rotational force with almost no deviation in the rotational direction. Therefore, while the side rod 23, the joint 24, and the center rod 25 are connected in the axial direction, the rotating rod 22d is curved as a whole and can be rotated integrally while following the curved shape of the center shaft 22a. .

  The roll shade portion 22B is fixed at the both ends to the roll shade holding portion 26b, disposed between the rear frame 3c and the trim member 5 covering this, as shown in FIG. The configuration is the same as that of the roll shade portion 22A except that it is curvedly attached along the rear frame 3c.

As described above, the roll shade portions 22A and 22B include the center shaft 22a and the rotating rod 22d and are configured to be bendable. Therefore, the roll shade portions 22A and 22B are sub-assembled to form the openings 2a and 2b. Applicable regardless of whether the upper side is linear or curved.
Further, since the rotation rod 22d is formed by connecting the side rod 23, the joint 24, and the center rod 25, even if the center shaft 22a is curved, the curved shape is maintained using the center shaft 22a as the rotation axis. As it is, it can be rotated while following its shape.
Further, since the roll shade portions 22A and 22B can be curvedly arranged, the roll shade portions 22A and 22B can be arranged in a narrow space or a space that could not be arranged conventionally, and the degree of freedom of the installation location of the roll shade portions 22A and 22B is improved. As a whole, the sunshade device S can be made compact.

In the present embodiment, the rotating rod 22d is configured by connecting the rigid side rod 23, the joint 24, and the center rod 25. Therefore, the rotating rod 22d is not twisted, and the seat is smoothly formed. 21b can be developed and stored.
For example, when the rotating rod 22d of the R-shaped roll shade portion 22B is formed of an elastic tube such as a vinyl hose and both ends of the elastic tube are supported rotatably, the elastic tube can be bent along the rear frame 3c. On the other hand, twisting occurs due to the elastic force and the winding of the sheet 21b is shifted at both ends. However, in this embodiment, the rotating rod 22d is formed of a rigid body, and thus such a problem does not occur. Furthermore, when the rotating rod 22d is formed of a curved resin tube, both sides of the tube can be swung so as to draw a large circular locus due to the rotation of the tube, but in this embodiment, the side rod made of a rigid body is used. 23, the joint 24, and the center rod 25 are connected to form the rotating rod 22d, so that such a problem does not occur.

  Further, since one end side of the coil spring 22b is connected to the rotating rod 22d via the spring holder 22c and the other end side is fixed to the center shaft 22a, the rotating rod 22d is a positive member for expanding the sheets 21a and 21b. When rotating in the direction, a rotational force is applied to the coil spring 22b in the direction in which the sheets 21a and 21b are accommodated, so that tension is applied to the sheets 21a and 21b during expansion and the sheets can be accommodated smoothly during accommodation.

The seats 21a and 21b are formed of a known sunshade sheet material for side door glass of a vehicle having a predetermined transmittance and hardly expanding or contracting in the extending / storing direction. The sheet 21a is formed in a substantially rectangular shape for shielding the substantially rectangular opening 2a, and the sheet 21b is formed in a substantially triangular shape for shielding the non-rectangular opening 2b close to the triangle.
The base ends of the sheets 21a and 21b are attached to the rotating rods 22d of the roll shade portions 22A and 22B, respectively. The sheets 21a and 21b covering the openings 2a and 2b are fed out from the roll shade portion 22B through slits of trim members (not shown) attached to the front frame 3a and the rear frame 3c.

It is connected to the rotating member 72 of the winding mechanism 70 that has been made.
The sheets 21a and 21b are wound around the rotating rods 22d of the roll shade portions 22A and 22B when stored, and are configured to be able to shield the openings 2a and 2b when extended.

  In the present embodiment, the slider 35 is directly attached to the left and right ends of the lower end side of the sheet 21a. However, the slider 35 has a long length that is slightly longer than the lower end side of the sheet 21a. A rigid guide member may be attached, and the sliders 35 may be attached to both ends of the guide member. The guide member may have a shape along the shape of the glass surface of the window glass 6a, such as a linear shape or a curved shape matching the curvature of the glass surface. By comprising in this way, it can prevent that a clearance gap is made between the sheet | seat 21a and the window glass 6a.

  The spiral cable 34 includes a coiled cable and a flexible flexible cable inserted through the entire length of the coiled cable. The upper end of the spiral cable 34 is fixed to the slider 35. The upper end portion of the spiral cable 34 is inserted into the guide groove of the guide rail 31, and the lower end portion is inserted into the cable pipe 32.

  The lower end side of the spiral cable 34 is inserted into the through hole of the cable pipe holder 33 while being inserted into the cable pipe 32. As shown in FIG. 4, in the cable pipe holder 33, a part of each of the two cable pipes 32 is notched in the length direction, and the spiral cable 34 is exposed from the notched part. An output gear 11a attached between the two spiral cables 34 is engaged with the exposed portion, and the spiral cable 34 and the output gear 11a function like a rack and pinion. When the motor device 11 is actuated and the output gear 11a rotates forward or backward, each spiral cable 34 meshed with the output gear 11a is sent out in the cable pipe 32 in the left and right direction. Since the spiral cable 34 is composed of a flexible cable and a coiled cable, the spiral cable 34 can smoothly move inside the cable pipe 32 bent at a right angle.

  As shown in FIG. 9, the slider 35 is formed integrally with the seat attachment portion 35 b made of a substantially rectangular plate and the sheet attachment portion 35 b, and has a shape that can be engaged with the guide groove of the guide rail 31. And a slide part 35a protruding from the attachment part 35b. The slide portion 35a has a substantially circular section that can be engaged in the guide groove of the guide rail 31, and a neck portion that integrally connects the substantially circular section with the seat mounting portion 35b. It consists of a cross-sectional shape and has the same cross-sectional shape over the length direction of the guide rail 31. As shown in FIG. 9, the sheet attachment portion 35b extends to the window glass 6a side (the sheet 21a side), and the left or right end portion of the lower end side of the sheet 21a is fixed. The slider 35 is movable between the upper end and the lower end of the guide rail 31 as the slide portion 35 a slides in the guide groove of the guide rail 31.

The output gear 11 a is disposed in the cable pipe holder 33 and is formed so as to be able to mesh with the spiral cable 34.
The spiral cable 34, the motor device 11, and the output gear 11a correspond to the first drive means of the present invention.

The winding mechanism unit 70 extends and stores the sheet 21b, and is attached to a space between the support column 9 and the trim member 5 as shown in FIGS. As shown in FIGS. 8 and 9, the winding mechanism unit 70 includes a guide shaft 71 fixed to the support column 9 in parallel with the guide rail 31, and a rotating member as a moving member that moves up and down along the guide shaft 71. 72, and a connecting member 73 that connects the rotating member 72 and the slider 35.
As shown in FIGS. 1 and 8, the guide shaft 71 is formed of a substantially cylindrical body having substantially the same length as that of the support column 9, and a spiral groove 71a is formed on the outer peripheral surface.
Since the ratio of the ascending or descending speed of the rotating member 72 and the rotating speed of the rotating member 72 depends on the inclination of the spiral groove 71a, the inclination of the spiral groove 71a is the surplus of the sheet 21b that is drawn obliquely to the lower left. It is set so that the part can be wound up exactly. That is, the lateral width of the surplus portion made of a right triangle is w (cm), the height is h (cm), the outer circumference length of the rotating member 72 is L (cm), and the height is displaced by the circumference of the spiral groove 71a1. When the difference in height, that is, the height difference between the upper end and the lower end when the spiral groove 71a goes around the outer periphery of the rotating member 72 is H (cm), w / h = L / H. Is set.
The guide shaft 71 extends along the guide rail 31 from the upper end to the lower end of the column 9. The upper and lower ends of the guide shaft 71 are fixed in the vicinity of the upper and lower ends of the column 9, respectively, and a predetermined gap is secured between the intermediate portion between the upper and lower ends of the guide shaft 71 and the column 9.

The rotating member 72 is formed of a hollow and substantially cylindrical body, and a through hole through which the guide shaft 71 is inserted in the axial direction is formed at the center. A fitting groove 72a as an annular groove perpendicular to the through hole of the rotating member 72 is formed annularly over the entire circumference slightly below the center of the outer peripheral surface of the rotating member 72. The left side edge of the free end of the sheet 21 b is fixed to the outer peripheral surface of the rotation member 72 so that the sheet 21 b is parallel to the through hole of the rotation member 72. On the inner peripheral surface of the rotating member 72, a sliding protrusion 72b is formed as a guide protrusion that can slide in the spiral groove 71a.
As shown in FIGS. 8 and 13, the rotating member 72 is provided around the outer periphery of the guide shaft 71.

The connecting member 73 is a member that connects the rotating member 72 and the slider 35, and is continuously connected to the rod-shaped joint portion 73a and one end of the joint portion 73a, and the rod body is bent into a U shape. The U-shaped part 73b as a holding part is formed of a substantially h-shaped member formed integrally. The inner periphery of the U-shaped portion 73 b is formed slightly larger than the fitting groove 72 a of the rotating member 72 so that the fitting groove 72 a can rotate and slide within the U-shaped portion 73 b.
As shown in FIGS. 8 and 12, the joint portion 73a is fixed to the lower end surface of the slider 35, and the U-shaped portion 73b engages with the fitting groove 72a of the rotating member 72 with play, Thus, the slider 35 and the rotating member 72 are connected by the connecting member 73, and the rotating member 72 is rotatable with respect to the slider 35.

  In the present embodiment, the U-shaped portion 73b is configured such that the inner and outer peripheral shapes are U-shaped, but the inner peripheral shape only needs to correspond to the fitting groove 72a. The shape may be C-shaped or annular, or the outer peripheral shape may be rectangular or circular. The fitting groove 72 a is recessed from the outer peripheral surface of the rotating member 72, but is not limited thereto, and may be provided at a location protruding from the outer peripheral surface of the rotating member 72. Instead of the fitting groove 72a, an annular protrusion may be formed on the outer peripheral surface of the rotating member 72, and a groove that can be engaged with the annular protrusion may be provided instead of the U-shaped portion 73b. Alternatively, annular guide grooves may be formed on the upper and lower end surfaces of the rotating member 72, and the connecting member 73 may be provided with protrusions that are inserted into the guide grooves from above and below.

  Next, the electrical configuration of the sunshade device S will be described with reference to FIG. The sunshade device S includes an operation switch 41 operated by an occupant, various sensors 42 to 45, and a control unit 40 that sends a drive signal to the motor device 11.

  The operation switch 41 is a switch that is operated when an occupant wants to expand and store the seats 21a and 21b, and is provided on an instrument panel, a door panel 2, and the like (not shown) of the vehicle. The operation switch 41 is normally in the center position and is a lever-type switch that can be tilted to one end side or the other end side by an occupant's operation. When the lever is tilted to one end side, the direction in which the seats 21a and 21b are extended When the lever is tilted to the other end, it is possible to instruct movement of the seats 21a and 21b in the storage direction, and when the occupant releases the hand, the seat 21a and 21b are restored to the center position. When the operation switch 41 is operated, an operation signal instructing to move or stop the movement of the sheets 21 a and 21 b in the extending or storing direction of the sheets 21 a and 21 b is sent to the control unit 40.

  When the occupant holds the operation switch 41 tilted to one end or the other end and releases the operation switch 41 to the center position when the seats 21a and 21b reach the desired positions, the control unit 40 The driving of the motor device 11 is stopped by the signal from the, and the sheets 21a and 21b can be stopped at a desired position.

The temperature sensor 42 is installed on the inner surfaces of the window glasses 6a and 6b, the seat back side surface of the driver's seat, and the like, detects the temperature in the passenger compartment, and sends a detection signal corresponding to the temperature to the control unit 40.
The optical sensor 43 is composed of one or more directional sensors, and is installed on the inner surfaces of the window glasses 6a and 6b. The illuminance of incident light entering the vehicle interior and the sunlight within a predetermined incident angle (direction) range. The incident can be detected. The optical sensor 43 may include a sensor provided with a directivity so that only the incident light having a predetermined incident angle can reach the sensor surface.

The position sensor 44 is a sensor that detects the stretched position of the sheets 21a and 21b. A plurality of limit switches are provided along the guide rail 31 and the guide shaft 71 in accordance with the storage position in FIG. 1, the shielding position in FIG. 3, etc., and the slider 35 and the rotating member 72 are brought into contact with the limit switch. A signal indicating contact from the limit switch is sent, and the control unit 40 can know the positions of the slider 35 and the rotating member 72 based on this signal. Note that the position sensor 44 may be configured to detect the expansion state in accordance with the rotation amount of the roll shade portions 22A and 22B.
The gear position sensor 45 is a sensor that detects the gear position of the vehicle, and detects that the gear is at a position such as a parking position or a drive position.

  The control unit 40 is constituted by a microcomputer, and receives an operation signal from the operation switch 41 and detection signals of the temperature sensor 42, the optical sensor 43, the position sensor 44, and the gear position sensor 45, and the motor device 11 based on these signals. A forward / reverse drive signal is sent to.

  When the control unit 40 determines that the temperature in the vehicle interior has become a predetermined temperature or higher, or sunlight having a predetermined illuminance or higher is inserted, based on signals from the temperature sensor 42 and the light sensor 43, the control unit 40 automatically transfers to the motor device 11. A driving signal is sent out to spread the sheets 21a and 21b and cover the window glasses 6a and 6b to block sunlight. The drive signal may be sent to the motor device 11 on the basis that a signal indicating that the gear is in the parking position is received from the gear position sensor 45, assuming that the vehicle is parked.

  In other words, when the vehicle is parked without the seats 21a and 21b being extended, when the control unit 40 determines that the temperature in the vehicle interior exceeds a predetermined value or strong sunlight has been inserted, the seat 21a is automatically set. , 21b are closed to suppress the temperature rise in the passenger compartment. Since the seats 21a and 21b are automatically extended during parking in this way, the temperature rise in the passenger compartment is suppressed even when the occupant returns, and an air conditioner blows out to drastically lower the temperature in the passenger compartment. There is no need to increase the amount, and a large amount of energy can be prevented from being consumed.

Further, the control unit 40 receives a signal indicating that the gear is in the drive position from the gear position sensor 45, determines that the vehicle is traveling, and determines the incident light based on the signal from the optical sensor 43. When it is determined that the illuminance is a predetermined value or more and the incident direction of the incident light is within the predetermined range, a driving signal is automatically sent to the motor device 11 to the middle position as shown in FIG. 21b is extended. When the sheets 21 a and 21 b are extended to a midway position, the control unit 40 stops sending the drive signal to the motor device 11 based on the detection signal from the position sensor 44.
Furthermore, when the control unit 40 determines that the illuminance and the incident direction are out of the predetermined range based on the signal from the optical sensor 43, the control unit 40 sends a reverse rotation drive signal to the motor device 11 and automatically performs the sheet 21a, 21b is stored.

  When the seats 21a and 21b are in the shielding position shown in FIG. 3 and the gear is shifted to the drive position during parking, the control unit 40 automatically sends a reverse rotation drive signal to the motor device 11. The sheets 21a and 21b may be moved to the storage position in FIG.

  When the sheets 21a and 21b reach the positions where they should be stopped during the operations of extending and storing the sheets 21a and 21b, the control unit 40 uses the signal from the position sensor 44 to reach the position where the sheets 21a and 21b are stopped. Detect and stop sending the drive signal at that position. When the drive signal transmission is stopped, the sheets 21a and 21b are held at the storage position, the shielding position, and the intermediate position between the storage position and the shielding position by the self-holding function (for example, clutch) of the motor device 11.

Next, operation | movement of the sunshade apparatus S of this embodiment is demonstrated.
Normally, the sheets 21a and 21b of the sunshade device S are in the storage position in FIG. 1 and are wound around the roll shade portions 22A and 22B. As shown in FIG. 1, in the state in which the sheet 21a is wound to the maximum extent by the roll shade portion 22A, the free end portion of the lower end of the sheet 21a is substantially at the same position as the upper end of the opening 2a. The free end portion of the sheet 21a may be wound up further upward. As shown in FIG. 1, the sheet 21b is drawn out from the left end portion of the roll shade portion 22B only in a state where the sheet 21b is wound up to the maximum extent by the roll shade portion 22B.
In the state of being in this stowed position, the vehicle occupant instructs the operation switch 41 to extend the seat 21a, or is parked or running based on detection signals from the temperature sensor 42, the optical sensor 43, and the gear position sensor 45. If it is determined that the vehicle interior temperature has reached a predetermined temperature or that sunlight with a predetermined illuminance or higher has been inserted, the control unit 40 transmits a drive signal for driving the motor device 11 to rotate in the forward direction. .

Based on this drive signal, the motor device 11 starts normal rotation, and the output gear 11a of FIG. 4 also starts normal rotation. When the output gear 11a rotates forward, the two spiral cables 34 that mesh with the output gear 11a move toward the lower end. Accordingly, the pair of sliders 35 fixed to the upper end of the spiral cable 34 starts to descend from the position of the upper end of the opening 2 a in FIG. 1, and the free end portion of the lower end of the sheet 21 a fixed to the slider 35 is also the slider 35. The sheet 21a is fed out from the roll shade portion 22A, passes through a slit of a trim member (not shown) of the upper frame 3b, and starts to expand. As the two sliders 35 are lowered, the sheet 21a is pulled out from the roll shade portion 22A with substantially the same width so that the lower end side is parallel to the lower parting line 2c of the horizontal opening 2a.
The right end portion of the free end portion of the sheet 21a is fixed to the slider 35 as shown in FIGS. 9 and 10, and the entire right end side is connected to the slit 5a and the guide members 7 and 8 as shown in FIG. The right side edge of the sheet 21a is straightly lowered along the slit 5a without being lifted or twisted from the surface of the window glass 6a. Since the front frame 3a also includes a slit (not shown) and a guide member (not shown), the same applies to the left side edge of the seat 21a.

At the same time, the rotating member 72 connected to the slider 35 by the connecting member 73 also receives a downward force from the slider 35. At this time, the sliding protrusion 72b is guided to the spiral groove 71a of the guide shaft 71. Therefore, the rotating member 72 descends while rotating counterclockwise.
As the rotating member 72 is lowered, the free end portion of the front end of the sheet 21b fixed to the rotating member 72 starts to descend in synchronization with the free end portion of the sheet 21a, and the sheet 21b is attached to the rear frame 3c. It passes through the lower side of the trim member (not shown) and is fed from the roll shade portion 22B. At this time, since the roll shade portion 22B is disposed obliquely, the sheet 21b is pulled out diagonally to the lower left rather than in a straight downward direction. Further, as shown in FIG. 11, due to the counterclockwise rotation of the rotation member 72, the sheet 21b is wound around the outer peripheral surface of the rotation member 72 and the guide shaft 71 from the free end, and is pulled leftward. It is done. The surplus portion of the sheet 21b is wound around the rotating member 72 and the guide shaft 71 from the left side edge, and the portion that is not wound is extended to the opening 2b.

  In this embodiment, in order to expand the sheet 21b that does not expand and contract in accordance with the shape of the opening 2b, the left side edge of the sheet 21b is wound from the free end side in synchronism with the drawing operation of the sheet 21b. It is wound up by the part 70. Thereby, when the sheet 21b is pulled out to the lower left, a portion that protrudes to the left of the opening 2b and becomes an excess portion is wound. Therefore, the sheet 21b is stretched so as not to sag from the upper side to the lower side of the opening 2b.

Further, as the sheet 21b is pulled out downward, the width of the pulled-out portion gradually increases. That is, the position of the right end portion of the drawn sheet 21b gradually moves obliquely downward from the left end portion of the roll shade portion 22B toward the right end portion (portion connected to the lower end portion of the opening 2b). In this embodiment, the downward movement of the right end portion of the sheet 21b is synchronized with the downward movement of the rotating member 72 of the winding mechanism portion 70 that is winding the left end portion of the sheet 21b. As shown, the lower end side of the sheet 21b being stretched is always substantially horizontal so as to be parallel to the lower parting line 2c of the horizontal opening 2b.
The free end portion of the sheet 21b is fixed to the rotating member 72 as shown in FIGS. 9 and 10, and the side end side of the sheet 21b on the column 9 side is provided with the slit 5b and the guide as shown in FIG. It is supported by the members 7 and 8, and the side edge of the sheet 21b on the support column 9 side is neither lifted nor touched by the surface of the window glass 6b.

When the operation switch 41 is returned to the center position in the middle position in FIG. 2, the control unit 40 receives a signal from the operation switch 41 to stop the stretching operation, or the control unit 40 receives the optical sensor 43, When it is determined that the illuminance of incident light is greater than or equal to a predetermined value or the incident direction is within a predetermined range while the vehicle is traveling based on the detection signal from the gear position sensor 45, the control unit 40 drives the motor device 11. To stop. As a result, the output gear 11a and the slider 35 are stopped, and the extending operation up to the middle position of the sheets 21a and 21b is completed.
2, when the position sensor 44 reaches the shielding position in FIG. 3, the position sensor 44 transmits a signal indicating that the sheets 21a and 21b are in the shielding position to the control unit 40. Based on the above, it is assumed that the shielding is completed, and the driving of the motor device 11 is stopped. As a result, the output gear 11a and the slider 35 are stopped, and the extending operation up to the shielding positions of the sheets 21a and 21b is completed.

In the storing operation of the sheets 21a and 21b, an operation opposite to the extending operation is executed.
When the operation switch 41 for instructing the storage of the seats 21a and 21b is selected by the vehicle occupant in a state where the seats 21a and 21b of the sunshade device S are in the middle position of FIG. 2 or the shielding position of FIG. When the control unit 40 determines that the illuminance and the incident direction are out of the predetermined range based on signals from the sensor 43 and the gear position sensor 45, or based on a signal from the gear position sensor 45, the control unit 40 However, when it is determined that the gear is shifted to the drive position, the control unit 40 transmits a drive signal for driving the motor device 11 to rotate in the reverse direction.
Based on this drive signal, the motor device 11 starts reverse rotation, and the output gear 11a of FIG. 4 also starts reverse rotation. When the output gear 11a rotates in the reverse direction, the two spiral cables 34 that mesh with the output gear 11a move upward. Accordingly, the pair of sliders 35 fixed to the upper end of the spiral cable 34 starts to rise from the position of the lower end of the opening 2 a in FIG. 3, and the free end of the lower end of the sheet 21 a fixed to the slider 35 is also the slider 35. The seat 21a starts to be stowed as it rises.

At the same time, the rotating member 72 connected to the slider 35 by the connecting member 73 also receives an upward force from the slider 35. At this time, the sliding protrusion 72 b is guided to the spiral groove 71 a of the guide shaft 71. Therefore, the rotating member 72 rises while rotating clockwise.
As the rotating member 72 moves up, the free end portion at the tip of the sheet 21b fixed to the rotating member 72 starts to rise in synchronization with the free end portion of the sheet 21a. Further, as shown in FIG. 11, due to the clockwise rotation of the rotating member 72, the sheet 21b wound around the outer peripheral surface of the rotating member 72 and the guide shaft 71 is unwound, and the window glass is unwound. It is fed to the 6b side and pulled rightward by the urging force of the coil spring 22b of the roll shade portion 22B. In this way, when the sheet 21b is lifted and rotated by the rotating member 72, the sheet 21b receives an upward and rightward force, is unwound from the rotating member 72 and the guide shaft 71, and is fed to the window glass 6b side. At the same time, the fed portion is wound on the roll shade portion 22B urged in the winding direction from the upper end.

As shown in FIG. 2, when the operation switch 41 is returned to the center position while the sheets 21 a and 21 b are stored halfway, the control unit 40 receives a signal from the operation switch 41 to stop the storage operation. In this case, the control unit 40 stops driving the motor device 11. As a result, the output gear 11a and the slider 35 are stopped, and the storing operation up to the middle position of the sheets 21a and 21b is completed.
When the storage position in FIG. 1 is reached via the intermediate position in FIG. 2, the position sensor 44 transmits a signal indicating that the sheets 21a and 21b are in the storage position to the control unit 40, and the control unit 40 is based on this signal. Then, the driving of the motor device 11 is stopped. Thereby, the output gear 11a and the slider 35 are stopped, and the storing operation of the sheets 21a and 21b is completed.

As described above, the driving force of the driving unit 10 is transmitted to the winding mechanism unit 70 of the present embodiment via the slider 35, and the rotating member 72 is lowered integrally with the slider 35. As a result, the sheet 21b is extended and stored in synchronization with the sheet 21a. Further, even when a sheet material that does not expand and contract is used, the sheet 21b does not sag during expansion and storage, and does not overlap with the adjacent sheet 21a.
Further, during the stretching, the shape of the sheet 21b and the method of winding the roll shade part 22B on the roll shade part 22B are such that the lower end side of the sheet 21b is always parallel to the lower parting line 2c of the horizontal opening 2a. Is set. Therefore, like the sheet 21a, the sheet 21b is stretched straight downward from above the opening 2b. Therefore, the winding mechanism part 70 of this embodiment can cover the substantially triangular opening 2b in the same direction as the rectangular opening 2a (from top to bottom). Further, like the sheet 21a, the lower end of the sheet 21b may be leveled so as to be parallel to the lower parting line 2c of the horizontal openings 2a and 2b, and the sheet 21b may be extended and stored with the lower ends of both sheets aligned. it can.

  With the above configuration, the sunshade device S of the present embodiment is configured so that the substantially rectangular opening 2a in the front portion of the door 1 is connected to the upper end of the opening 2a based on the operation of the drive unit 10 and the guide unit 30. The substantially rectangular sheet 21a can be extended and stored between the lower ends, and the opening 2a can be shielded from above. At this time, since both side ends of the sheet 21a are supported by the slits 5a of the trim member 5, no gap (uncovered portion) is generated between the sheet 21a and the front frame 3a or the support column 9. Therefore, the opening 2a can be covered with good appearance.

  Further, the sunshade device S of the present embodiment also has an upper end of the opening 2b based on the operation of the winding mechanism unit 70 that is interlocked with the guide unit 30 for the substantially triangular opening 2b at the vehicle rear portion of the door 1. The substantially triangular sheet 21b can be extended and accommodated between the lower end and the lower end, and the opening 2b can be shielded from above. At that time, the extra portion of the sheet 21b is wound so that the non-stretchable sheet 21b can be stretched so as not to sag, and the lower end of the sheet 21b is always stretched horizontally. Further, since the left end portion of the sheet 21b is supported by the slit 5b of the trim member 5, no gap (uncovered portion) is generated between the sheet 21b and the support column 9. Therefore, the opening 2b can be covered with good appearance.

Further, in the sunshade device S of the present embodiment, the winding mechanism unit 70 is operated based on the output of the driving unit 10 in conjunction with the guide unit 30, so that one driving source is used to drive the two sheets. All that is required is to simplify the configuration. Further, since the sheet 21a and the sheet 21b can be synchronously pulled out in the same direction and the lower ends thereof can be lowered at the same height, the two sheets are unfolded and the window glass 6a looks good. , 6b can be covered.
Further, in the sunshade apparatus S of the present embodiment, the sheets 21a and 21b can be expanded without being expanded and contracted in this way, so that the sheets 21a and 21b are not stretched and contracted during the expansion and cannot be wound smoothly. Such a problem does not occur.

Further, in the sunshade apparatus S of the present embodiment, since the sheets 21a and 21b cover the openings 2a and 2b from above, one or more intermediate stop positions are provided between the storage position and the shielding position. If the seats 21a and 21b are automatically extended to these halfway stop positions during driving of the vehicle, the sunshade device S of this embodiment can be used as a visor and shade. You can also When used as a sun visor, the sunshade device S can be automatically extended, so that the sunlight can be blocked by the seats 21a and 21b without the occupant operating the operation switch 41.
The occupant can also use the sunshade device S of this embodiment as an insect repellent by lowering the seats 21a and 21b while lowering the window glass 6a or 6b and opening the window. Further, by lowering the seats 21a and 21b to a predetermined position, it is possible to prevent wind from hitting the upper body such as the head during traveling.

Further, in the sun shade device S of the present embodiment, the drive unit 10, the roll shade mechanism unit 20, the guide unit 30, and the winding mechanism unit 70 that are constituent members are arranged between the door panel 2 and the door trim (not shown) or the trim member 5. The sunshade device S does not get in the way even when not in use. Moreover, since it cannot be seen from the passenger compartment side, the appearance is good. Furthermore, since the sunshade device S is disposed not on the vehicle side but on the door side, it is preferable because it does not interfere with the operation of the curtain shield airbag.
In addition, if the material of the sheets 21a and 21b is changed variously and set to an appropriate light transmittance, the sunshade device S can also function as a smoke film.

Moreover, although the example which applied the sunshade apparatus S to the door window of the right rear door of a vehicle was shown in this embodiment, you may apply the sunshade apparatus S to not only this but all the side windows. The side window can include all of the door window, a fitting window disposed on the side surface of the vehicle, and a window that can be opened and closed, in addition to the door window. In this way, the temperature rise in the passenger compartment can be further suppressed. Further, the sunshade device S can be applied to a non-rectangular front window and rear window.
