Description

  The present invention relates to a sunshade device, and more particularly to a sunshade device for covering a window of a vehicle and blocking sunlight.

When a car is parked in hot weather, if sunlight enters the passenger compartment, the temperature inside the vehicle rises, and it is very hot and uncomfortable when getting on again. Even if the air conditioner is operated in such a state, the warm wind blows out at first, which not only increases discomfort, but also takes time to lower the vehicle interior temperature. In addition, if the temperature is to be suddenly lowered, it is necessary to increase the amount of ejection from the air conditioner, and a large amount of energy is required.
Conventionally, in order to prevent sunlight from entering the passenger compartment, a separate sunshade is leaned against the inside of the window or attached to the window with a sucker or the like. However, another conventional sunshade is inconvenient because it requires a place to store when not in use, and the appearance is not good.

  As a technique for solving the above inconvenience, a sunshade device built into a vehicle is known (for example, see Patent Document 1). In this technology, a blind sheet that shields sunlight by covering a window is expanded and stored by rotating the winding storage device, and this winding storage device is installed at the upper edge of the indoor side of the window. It is arranged linearly along the longitudinal direction. Even when the passenger seat airbag is mounted on the dashboard at the bottom of the front window, the winder storage device is installed along the upper edge of the window, so the passenger seat airbag is retracted and stored. The sunshade device can be disposed on the front window without disturbing the disposition of the device.

In the known technique, the base end portion of the rectangular blind sheet is fixed to the take-up and storage device, and a tubular stay is attached to the free end side. Slide shafts are respectively inserted into both end portions of the stay, and the slide shaft is supported so as to advance and retreat with respect to the axial direction of the stay. A runner is attached to the outer end of the slide shaft.
A guide rail is disposed inside the pillar to which the window is attached, and the runner is guided by the guide rail and can move up and down. Further, a flexible linear member whose lower end portion is coupled to the runner is disposed in the guide rail, and the flexible linear member is configured to be movable in the guide rail by a driving device.

With the configuration described above, the sunshade device of Patent Document 1 moves up and down along the length direction of the guide rail when the driving device is activated and the flexible linear member moves in the guide rail. Then, the blind sheet is stored and extended.
Further, since the window of the vehicle has a trapezoidal shape that is wider toward the lower side, the distance between the guide rails is increased toward the lower side. For this reason, in this sunshade device, the slide shaft moves forward and backward with respect to the stay in accordance with the distance between the guide rails, and the length of the stay and the slide shaft as a whole is adjusted.
As described above, the sunshade device according to the prior art can be operated when necessary to extend the blind sheet to cover the window and shield sunlight. Further, unlike the conventional standing type sunshade, this sunshade device does not need to secure a storage place when not in use, and has an excellent appearance because it is integrated into the vehicle.

JP 2000-52763 A (page 2-6, FIG. 1-9)

  However, since the windows of the vehicle (front window, rear window, side window) have a trapezoidal shape that is wider toward the bottom, the sunshade device completely covers the entire window even when the blind seat is fully extended. Cannot be covered, and a substantially triangular gap (uncovered portion) is formed on both outer sides, and sunlight enters into the vehicle compartment from there, causing a problem that the temperature inside the vehicle rises.

  In addition, the front window of the vehicle has a complex shape that is curved so that it protrudes forward toward the center in the width direction when viewed from the vehicle interior, and the rear window is curved so that it protrudes backward toward the center in the width direction. Has the shape. Therefore, when the take-up roll that winds up the blind sheet is arranged on the roof side, due to this curved shape, it is shifted behind the window on the front window side and forward of the window on the rear window side. Must. However, in order to avoid interference with a sunroof or the like and to secure a space in the vehicle interior, it is desired to arrange a winding roll as close to the window as possible.

In view of the above problems, an object of the present invention is to allow sunlight to enter the vehicle interior by covering substantially the entire area of a vehicle window having a complicated shape having a curvature in the front-rear and left-right directions in which the width is not constant in the vertical direction. It is an object of the present invention to provide a sunshade device that can prevent this.

This is solved by rotating around the center shaft following the curved shape of the center shaft.

The joint between the front (rear) window and the body of the vehicle has a curved line, and the roll shade is attached to the vicinity of the window by arranging the roll shade so as to be curved in accordance with the joint. It becomes possible. Thereby, even when a sunroof is provided in the vehicle, for example, the distance between the sunroof and the roll shade can be ensured so as not to interfere with each other. Further, as described above, the space between the sunroof and the roll shade portion is secured, and for example, the drive portion of the roll shade portion is disposed in this space so that the roll shade portion and the drive portion do not overlap vertically. Since it can comprise, the space in a vehicle can be ensured.
Moreover, the upper part of the door window of the vehicle has a curved shape, and the roll shade portion can be disposed along the door window by curving the roll shade portion in accordance with the curved shape. Accordingly, the sunshade device can be disposed in a space that cannot be disposed conventionally, and the entire configuration can be made compact.

It can be moved along the side edges of the vehicle window. Along with the movement, the slide shaft can advance and retreat with respect to the guide member attached along the free end side of the blind sheet. Since this guide member moves along the guide rail with the movement of the slide shaft, the blind seat can be extended and stored along the edge of the window of the vehicle.

  The blind sheet can be expanded and contracted, and is preferably expanded or contracted according to the width of the window as it is extended from the roll shade part or stored in the roll shade part. In general, the width of the window is not constant and has a shape closer to a trapezoid than a rectangle, and the width is usually wider on the lower side. For example, when the roll shade part is provided on the upper side and the blind sheet has a constant width and is formed of a sheet material that is not stretchable in the width direction, a substantially triangular gap (uncovered part) on both sides or one side of the window ) Will be formed. However, in the present invention, since the blind sheet can be expanded and contracted in the width direction, the blind sheet can be expanded in the width direction according to the width of the window. Thereby, it becomes possible to cover substantially the entire region without covering the window with the blind sheet.

  The blind sheet is extendable, and both end portions of the side of the free end side of the blind sheet are attached to the slide shaft or the slider, and the blind sheet is extended from the roll shade portion or from the roll shade portion to the roll shade portion. The blind sheet is preferably expanded and contracted according to the width of the window as it is stored. In this way, if the blind sheet is configured to be able to expand and contract in the width direction, for example, in the case of a trapezoidal window, the slide shaft extends to the left and right as the tip of the blind sheet moves to the lower side of the window, As a result, the blind sheet is pulled and stretched left and right, and the blind sheet can cover substantially the entire area of the window without generating the gap.

Engaging protrusions 25 a similar to the engaging protrusions 23 a of the side rod 23 are formed at both ends of the center rod 25. However, at both ends of the center rod 25, engagement protrusions 25a are formed at positions shifted in phase by approximately 90 degrees in the circumferential direction.

  The joint 24 connects the side rod 23 and the center rod 25 or the center rods 25 in the axial direction. For this reason, engagement recesses 24 a that engage with the engagement protrusions 23 a or the engagement protrusions 25 a are formed at two positions on each end of the joint 24. Further, like the center rod 25, the engaging recess 24a is formed at a position shifted by approximately 90 degrees in the circumferential direction at both ends. The engagement protrusions 23a and 25a of the side rod 23 and the center rod 25 are fitted into the engagement recesses 24a of the joint 24, and these are connected to each other.

Since it is configured in this way, the rotating rod 22d including the side rod 23, the joint 24, and the center rod 25 can be connected in the axial direction while being inserted into the center shaft 22a. When these parts are sub-assembled to assemble the roll shade portion 22, the side rod 23, the joint 24 and the center rod 25 are assembled with a space margin (play). With this play, the side rod 23 or the center rod 25 connected to both sides of the joint 24 via the joint 24 can be bent approximately every 90 degrees with the joint 24 as a joint portion.
In this embodiment, the engagement protrusions 23a, 25a and the engagement recess 24a are simply connected to each other, but can be rotated by a hinge pin or the like so that it can be easily bent as a joint. You may connect.

  Further, the circumferential widths of the engaging protrusions 23a and 25a are formed to be approximately the same as the circumferential width of the engaging recess 24a, and when the rotating rod 22d rotates around the center shaft 22a as a rotating shaft, The rod 23, the joint 24, and the center rod 25 can transmit rotational force with almost no displacement in the rotational direction. Therefore, even when the side rod 23, the joint 24, and the center rod 25 are connected in the axial direction, it can be rotated as a whole while following the curved shape of the center shaft 22a while being curved as a whole. Yes.

  Since the roll shade part 22 is configured in this way, the roll shade part 22 that is sub-assembled can be bent along the reinforcement 4 and both ends can be attached to the roll shade holding part 26 and fixed. it can. At this time, the center shaft 22a is fixed to the roll shade holding portion 26, and the rotating rod 22d disposed around the center shaft 22a can rotate while following the shape of the curved center shaft 22a. That is, even if the rotating rod 22d rotates about the center shaft 22a as the rotation axis, the curved shape of the center shaft 22a is maintained, and the roll shade portion 22 remains along the curved shape of the reinforcement 4.

Here, as a comparative example, a case where the roll shade portion 22 is formed of an elastic tube such as a vinyl hose and both ends of the elastic tube are rotatably supported by the holding portion will be considered. In this case, the elastic tube can be bent along the reinforcement 4 due to the elastic force, but a twist occurs due to the elastic force and the blind sheet is unwound at both ends. Moreover, when the tube | pipe of the resin material etc. which carried out the curve shaping | molding is used as the roll shade part 22, the malfunction that both sides will swing so that a big circular locus may be drawn by rotation of pipe | tubes, such as a resin material, will generate | occur | produce.
In order to prevent the occurrence of such a shift, the roll shade portion 22 needs to use a rigid body (center rod 25 or the like) as in the present invention. It becomes impossible to unfold and store the blind sheet 21. Therefore, in the present invention, the rotating portion of the roll shade portion 22 is configured such that a plurality of center rods 25 and side rods 23 at both ends are connected via joints 24.

  Further, since one end side of the coil spring 22b is fixed to the center shaft 22a and the other end side is connected to the rotating rod 22d via the spring holder 22c, the rotating rod 22d rotates in the forward direction in which the blind sheet 21 is stretched. When it moves, a rotational force is applied to the coil spring 22b in the direction in which the blind sheet 21 is accommodated, and tension is applied to the blind sheet 21 during expansion and the accommodation is smooth even during accommodation.

The blind sheet 21 of this embodiment has a predetermined transmittance and hardly expands / contracts in the extending / storing direction, but can expand / contract as a whole in the width direction (direction perpendicular to the extending / storing direction). ing. In this example, the blind sheet 21 is formed of a stretchable sheet material. Moreover, the blind sheet 21 has a substantially rectangular shape in a natural state. For example, as a sheet material that can be expanded and contracted in the width direction, a material that can be expanded and contracted is used as a filamentous line material woven in the width direction. Further, even if the filamentous wire material itself is not so stretchable, it can be formed so as to have stretchability in the width direction depending on the weaving method. 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.
The blind sheet 21 may be anything that can expand and contract as a whole in the width direction. For example, a blind sheet is formed by connecting a stretchable sheet material and a non-stretchable sheet material in the width direction by sewing or the like. 21 can also be used.
In addition, a sheet material that can be expanded and contracted in the width direction only near the left and right ends is adopted, and a sheet material that has little elasticity in the width direction is adopted in the central portion attached to the guide pipe 27, and these are connected by sewing or the like The blind sheet 21 can be used.

At the free end of the blind sheet 21, a hollow guide pipe 27 that is bent in a slightly V shape at the center and has straight portions on the left and right is attached (see FIG. 1). As shown in FIG. 6, slide shafts 28 are inserted into the left and right ends of the guide pipe 27 so as to be able to advance and retreat. A coil spring is disposed inside the guide pipe 27, one end of the coil spring is fixed inside, and the other end is fixed to the insertion end of the slide shaft 28, thereby urging the slide shaft 28. You may do it.
Further, the guide pipe 27 may be curved with a certain curvature according to the curved shape of the window W. In this case, the slide shaft 28 inserted into the guide pipe 27 is also shaped to match this curvature, so that the slide shaft 28 can be advanced and retracted with respect to the guide pipe 27.

The left and right ends of the free end side of the blind sheet 21 are attached to the outer portion of the slide shaft 28. As described above, since the distance between the left and right guide rails 31 increases toward the lower side of the window W, when the slider 35 moves downward, the slide shaft 28 inserted into the guide pipe 27 gradually increases. It will be drawn to. As the slide shaft 28 is pulled out from the guide pipe 27 in this way, the blind sheet 21 is pulled outward by the slide shaft 28 and extends in the width direction.
Thus, in the apparatus S of the present embodiment, it is possible to cover substantially the entire area of the window W when the blind sheet 21 is expanded. That is, there is no triangular gap (uncovered portion) outside the window W as in the prior art, and it is possible to prevent problems such as the sunlight entering the passenger compartment through the gap and increasing the temperature in the passenger compartment. it can.

FIG. 11A shows a state where the blind sheet 21 is taken up (accommodated position) and FIG. 11B shows a state where the blind sheet 21 is fully extended (shielded position). Thus, in the apparatus S of the present embodiment, it is possible to cover substantially the entire area of the window W at the shielding position, and it is possible to shield sunlight insertion.
In the above-described embodiment, the left and right end portions on the free end side of the blind sheet 21 are attached to the outer portion of the slide shaft 28. The left and right ends may be attached to the slider 35 so that it can be pulled in the direction.

  Next, the electrical configuration of the device S will be described based on FIG. The device S includes a control unit 40 that sends a drive signal to the motor device 11 of the drive unit 10 that expands and stores the blind sheet 21. The control unit 40 is configured by a microcomputer, and includes an operation signal from an operation switch 41 that can be operated by an occupant, a detection signal from a temperature sensor 42 that detects the temperature in the vehicle interior, and light incident on the vehicle interior. The detection signal from the optical sensor 43 that detects the illuminance and the incident direction (angle), the detection signal from the position sensor 44 that detects the extended position of the blind seat 21, and the gear position sensor 45 that detects the gear position of the vehicle A detection signal or the like is received, and a drive signal in the forward / reverse direction is sent to the motor device 11 based on these signals.

  The operation switch 41 has a plurality of switches corresponding to storage, expansion, etc., and when the occupant wants to expand or store the blind seat 21, one of the switches is selected and operated, and an operation signal corresponding to the switch is sent. It is sent to the control unit 40. The control unit 40 that has received the operation signal sends a drive signal corresponding to either the forward or reverse rotation direction to the motor device 11 in accordance with the operation signal.

Further, the temperature sensor 42 and the optical sensor 43 are respectively disposed at predetermined locations in the passenger compartment, for example, the inner surface of the window W, the upper portion of the dashboard, and the like. The temperature sensor 42 detects the temperature in the vehicle interior and sends a detection signal corresponding to the temperature to the control unit 40, and the optical sensor 43 detects the illuminance and incident direction of sunlight that is inserted into the vehicle interior. .
The optical sensor 43 can detect that sunlight is incident within a predetermined incident angle (direction) range together with the illuminance of incident light into the vehicle interior. The optical sensor 43 includes one or more directional sensors, and detects that sunlight is incident within an angle range that is incident on the height of the eyes of a driver or a person sitting in a passenger seat. .
In addition, the optical sensor 43 includes a sensor having directivity by providing a slit portion on the front surface of the sensor so that only incident light with a predetermined incident angle can reach the sensor surface. Also good. Other than the inner surface of the window W and the upper portion of the dashboard, the optical sensor 43 can be disposed on a mirror stay.
The control unit 40 monitors these detection signals. If the detection signal determines that the temperature in the vehicle interior exceeds a predetermined value or that sunlight with a predetermined illuminance or higher is inserted, the vehicle is parked from the gear position sensor 45. A drive signal is automatically sent to the motor device 11 to expand the blind sheet 21 on the condition that a detection signal indicating that the vehicle is in the middle, and the window W is covered to block sunlight. For example, the control unit 40 determines that the vehicle is parked when the gear is in the parking position.

  That is, when the vehicle is parked without the blind sheet 21 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 blind sheet 21 is automatically set. Is closed so that the temperature rise in the passenger compartment can be suppressed. By automatically extending the blind seat 21 during parking in this way, the temperature rise in the passenger compartment is suppressed even when the occupant returns. It is not necessary to increase the amount of ejection, and a large amount of energy can be prevented from being consumed.

The position sensor 44 is a sensor for detecting the extended position of the blind sheet 21. For example, a plurality of limit switches are provided along the guide rail 31 in accordance with the storage position (FIG. 13A), the shielding position (FIG. 13C), etc., and the slider 35 and the limit switch come into contact with each other for the limit. A signal indicating contact from the switch is sent, and the control unit 40 can know the position of the slider 35 based on this signal.
Further, the expansion state may be detected according to the rotation amount of the roll shade unit 22 and a detection signal may be sent to the control unit 40.
The control unit 40 receives a detection signal from the position sensor 44 when the blind sheet 21 is extended and stored by automatically or manually sending a drive signal to the motor device 11 and is in the storage position, the shielding position, or the like. And the transmission of the drive signal can be stopped at this position. Then, the blind seat 21 can be held at a storage position, a shielding position, a midway position, or the like by a self-holding function (for example, a clutch) provided in the motor device 11 in a state where the drive signal transmission is stopped.

  Moreover, the apparatus S of this example can also be used instead of a sun visor. In the apparatus S of the present example, one or a plurality of halfway stop positions are provided between the storage position and the shielding position, and the blind seat 21 is automatically extended to the halfway stop position during operation of the vehicle. It is configured. FIG. 13 schematically shows the apparatus S. 3A shows the case where the blind sheet 21 is in the storage position, FIG. 3C shows the case where it is in the shielding position, and FIG. 3B shows the case where it is in the middle position.

On the condition that the control unit 40 receives a signal indicating that the vehicle is running from the gear position sensor 45, the illuminance of the incident light is a value greater than or equal to a predetermined value based on the detection signal from the optical sensor 43, When it is determined that the incident direction of incident light is within a predetermined range, a drive signal is automatically sent to the motor device 11 so that the blind sheet 21 is extended to an intermediate position. When the blind sheet 21 is extended to a midway position, the control unit 40 stops sending the drive signal to the motor device 11 by 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 is automatically rotated backward to the motor device 11 in order to store the blind sheet 21 automatically. The drive signal is transmitted.
Correspondingly, the operation switch 41 is also provided with a switch that extends to a middle position. The control unit 40 determines that the vehicle is running, for example, when the gear is in the drive position.

  When the gear is shifted to the drive position when the blind seat 21 is in the shielding position during parking, the control unit 40 automatically sends a reverse rotation drive signal to the motor device 11 to blind the blind seat 21. May be moved to the storage position. Even when the gear is in the drive position, the blind seat 21 may be moved to the shielding position when the operation switch 41 is operated manually.

  Conventionally, a vehicle is provided with a thin plate visor for a driver seat and a passenger seat. The sun visor is provided with a hinge portion at the front portion of the vehicle, and the occupant shields sunlight by rotating the sun visor forward from the near side with the hinge portion as a rotation center. Due to such a configuration, when the sun visor is rotated, the sun visor passes near the passenger's head, which may hinder driving. However, as described above, the device S also has a function as a sun visor, and according to the device S, there is no hindrance to driving such as passing near the overhead like a conventional sun visor. Further, since the device S is configured to automatically expand, it is preferable because the occupant can block the sunlight with the blind seat 21 without operating the operation switch 41.

  In addition, although the example which applied the apparatus S to the front window W was shown in the said Example 1, it is needless to say that it is applicable not only to this but a rear window and a side window. Moreover, although the example which has arrange | positioned the roll shade mechanism part 20 along the upper edge part of the window W was shown, you may arrange | position along the lower edge part of the window W. FIG.

In the first embodiment, the guide pipe 27 and the slide shaft 28 as the guide members are attached along the free end side of the blind sheet 21. However, the present invention is not limited to this, and as shown in FIG. In addition, the left and right end portions of the blind sheet 21 on the free end side may be fixed to the slider 35 so that the guide pipe 27 and the slide shaft 28 are not used.
In this case, the free end side of the blind sheet 21 is maintained in a planar shape by the tension generated when the blind sheet 21 is pulled left and right. In this way, the guide pipe 27 and the slide shaft 28 are not necessary. Thereby, a structure can be made simpler and it can contribute to manufacturing cost reduction and weight reduction.
At this time, the blind sheet 21 may be anything that can expand and contract as a whole in the width direction. For example, a blind sheet 21 may be formed by connecting a stretchable sheet material and a non-stretchable sheet material in the width direction by sewing or the like.
In the first embodiment, the shape of the window W is a trapezoid that is wider toward the lower side. However, the shape is not limited to this, and the upper side and the lower side have substantially the same width, or the lower side is wider. It may be a narrow window. In the present invention, since the blind sheet 21 covering the window W is formed of a stretchable sheet material, the blind sheet 21 can be expanded and contracted according to the width of the window W. Therefore, the blind sheet 21 can cover the window W regardless of the shape of the window W.

(Example 2)
Next, the Example which applied the apparatus S of this invention to the door window as a side window of the vehicle 1 is shown. This embodiment is an example in which the device S is applied to a front side door 101 (hereinafter referred to as “door 101”). The description of the same components as those in the first embodiment is omitted.
FIG. 15 is an explanatory view of the right door 101 as viewed from the inside of the vehicle, with a part cut away. A state is shown in which the blind sheet 121 of the device S is extended to a midway position between the storage position and the shielding position.
The door 101 is configured with a door trim 104 attached to the inside of the door panel 102. A window frame 103 is formed on the upper side of the door panel 102, and a trim member 105 is attached to the inside of the window frame 103. The trim member 105 is attached to the inside of the vehicle along the front frame 103a, the upper frame 103b, and the rear frame 103c of the window frame 103. The trim member 105 and the door trim 104 may be integrally formed. The front frame 103a and the rear frame 103c are frames arranged in the vertical direction extending upward from the door panel 102 main body. And the window glass 106 is arrange | positioned so that the opening part 102a formed with this window frame 103 may be plugged up. The window glass 106 can be moved up and down so as to close the opening 102a by a driving device (not shown).
The opening 102a of the window frame 103 has a trapezoidal shape, and the upper side is narrower than the lower side. In the window frame 103 of this example, the front frame 103a extends obliquely upward from the door panel 102 main body side, and the rear frame 103c extends in a substantially vertical direction. The connecting portion between the front frame 103a and the upper frame 103b has a rounded shape with a predetermined curvature.

The apparatus S of this example is disposed on the door 101 as described above, and includes a drive unit 110, a roll shade mechanism unit 120, and a guide unit 130.
The drive unit 110 is disposed between the door trim 104 and the door panel 102. The drive unit 110 of this example includes an electric motor 111 and a speed reduction mechanism 112, and a cylindrical reel 113 for winding a wire 132 as a transmission member is attached to the output side of the speed reduction mechanism 112. As the electric motor 111, various motors such as a DC motor, a brushless motor, and an ultrasonic motor can be applied. An operation switch 114 having operation positions such as lowering and raising is connected to the drive unit 110. When the occupant operates the operation switch 114 to the raised position or the lowered position, a current flows through the electric motor 111 and the reel 113 is operated. Rotates forward and backward, and the device S operates.

The roll shade mechanism 120 of this example includes a roll shade 122, a roll shade holder 126 that is disposed at both ends of the roll shade 122 and supports the rotation of the roll shade 122, and the roll shade 122. A blind sheet 121 that is attached to the base end and covers the opening 102a of the window frame 103 is provided.
The blind sheet 121 of this example has elasticity as a whole like the blind sheet 21 of Example 1.

The roll shade portion 122 is a cylindrical component, and is curved along the front frame 103a and the upper frame 103b of the window frame 103 so as to be along the edge of the window glass 106 when the window glass 106 is closed. It is installed. The roll shade portion 122 is disposed between the window frame 103 and the trim member 105 that covers the window frame 103. A slit 105a is formed in the trim member 105 toward the inside of the opening 102a. The blind sheet 121 is configured so as to be drawn out from the roll shade portion 122 through the slit 105a and cover the opening 102a. Thus, since the roll shade part 122 can be curved and arranged along the window frame 103 as well as the straight part, the degree of freedom of arrangement of the roll shade part 122 such as being arranged in a narrow space is improved. In addition, the apparatus can be configured compactly as a whole. Further, the apparatus S can be arranged in a space that could not be arranged conventionally.
Similar to the first embodiment, the roll shade portion 122 of this example includes a center shaft 22a fixed to the door 101, a coil spring 22b, a spring holder 22c, and a rotating rod 22d. The rotating rod 22d is configured by connecting a side rod 23, a joint 24, and a center rod 25. Therefore, the roll shade part 122 of Example 2 also has flexibility as a whole like the roll shade part 22 of Example 1.

  A bracket 126a is disposed on the front side of the upper frame 103b. The bracket 126a is located near the center of the roll shade portion 122 in the length direction, and the bracket 126a is slidably contacted with the outer periphery of the roll shade portion 122 in order to prevent the roll shade portion 122 from rotating when the roll shade portion 122 is rotated. The part 122 is supported.

As shown in FIGS. 15 and 16, the guide portion 130 of this example includes a guide rail 131 disposed between the rear frame 103 c and the trim member 105, and the guide rail 131 is guided in the guide rail 131. The slider 135 is configured to include a slider 135 that can move along the length direction, a wire 132 that is inserted into the guide rail 131 and has an end connected to the slider 135, and the like.
The slider 135 includes a slide part 135a having a substantially semicircular cross section and a sheet attachment part 135b formed integrally with the slide part 135a. The rear end portion of the free end of the blind sheet 121 is fixed to the seat attachment portion 135b. The slide portion 135a is slidably held on a guide rail 131 having a slit formed on the inner side (window center side).

  One end of the wire 132 is connected and fixed to the slide portion 135 a, passes through the guide rail 131 and is guided to the drive portion 110 via the pulley 133. The other end of the wire 132 is attached to the reel 113 of the drive unit 110, and the drive unit 110 can wind the wire 132. In this example, the wire 132 is guided to the drive unit 110 via the pulley 133. However, the present invention is not limited to this, and an introduction medium member other than the pulley 133 is arranged to guide the wire 132 to the drive unit 110. 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 132 may be slid in the pipe or in the groove by passing the wire 132 into the pipe or placing the wire 132 in the groove. In addition, a member having a groove may be arranged at a position where the direction of the wire 132 is changed, and the direction of the wire 132 may be changed.

Next, operation | movement of the apparatus S of this example is demonstrated. As described above, when the occupant operates the operation switch 114 to the lowered position, the drive unit 110 rotates in the forward direction and the reel 113 rotates in the forward direction. Thereby, the wire 132 is wound around the reel 113. As the wire 132 is wound up, the slider 135 moves downward along the guide rail 131 accordingly.
As the slider 135 moves downward, the blind sheet 121 is pulled downward by the slider 135, and accordingly, the roll shade portion 122 rotates forward and the blind sheet 121 is fed out through the slit 105a. At this time, a rotational force is applied to the roll shade portion 122 in the direction of winding the blind sheet 121 by the coil spring 22b. Therefore, the blind sheet 121 is pulled out from the roll shade portion 122 in a state where an appropriate tension is applied.
As shown in FIG. 17, since the blind sheet 121 is particularly stretchable in the width direction, the slider 135 moves downward, and the width of the opening 102a to be covered by the blind sheet 121 is increased. However, the blind sheet 121 can follow the width and expand in the width direction. Thereby, in the apparatus S of this example, it is possible to cover substantially the entire region of the window frame 103 having the trapezoidal opening 102a.

The occupant can lower the blind seat 121 to a desired position by holding the operation switch 114 in the lowered position. If the operation switch 114 is returned to the neutral position, the drive of the drive unit 110 is stopped and the drive unit 110 is stopped. The blind sheet 121 can be held at the position by the provided self-holding function (for example, clutch). Further, when the occupant wants to raise the blind seat 121, the occupant operates the operation switch 114 to the raised position. As a result, the drive unit 110 rotates in the reverse direction, and accordingly, the blind sheet 121 is wound up by the rotational force in the winding direction by the coil spring 22b applied to the roll shade unit 122. When the slider 135 moves to the upper end position, the blind sheet 121 can be accommodated in the trim member 105.
It should be noted that a limit switch may be provided at the upper end position, the lower end position, and an intermediate position where the slider 135 is movable, and the supply of current to the drive unit 110 may be stopped when the limit switch is activated. .

As described above, the apparatus S of the present example can cover substantially the entire region of the opening 102a of the window frame 103, and can thereby 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 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, if the material of the blind sheet 121 is changed in various ways and set to an appropriate light transmittance, the device S can also function as a smoke film.

Moreover, in the apparatus S of this example, since the roll shade part 122 is arrange | positioned along the front frame 103a and the upper frame 103b of the window frame 103, the blind sheet 121 may cover the opening part 102a from the upper side. And can provide a function as a visor. 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 blind sheet 121 while the window glass 106 is lowered and the window is opened. Further, by lowering the blind sheet 121 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 110, the roll shade mechanism unit 120, and the guide unit 130, which are constituent members, are disposed between the door panel 102 and the door trim 104 or between the door panel 102 and the trim member 105. 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.

  Further, the electrical configuration (not shown) of the device S of the second embodiment may be configured as shown in FIG. 12 of the first embodiment. In this case, similarly to the operation switch 41 of the first embodiment, the operation switch 114 of the second embodiment is connected to the control unit, and the electric motor 111 is connected to the control unit. In this way, in addition to the manual operation by the operation signal from the operation switch 114, the detection signal from the temperature sensor, the optical sensor, the position sensor, and the gear position sensor causes the drive signal from the control unit to the electric motor 111 to be forward and reverse. The blind sheet 121 can be automatically expanded and stored. At this time, you may integrate so that one control part may control the expansion | deployment and accommodation operation | movement of the blind seats 21 and 121 with respect to a front window (and rear window) and a door window, respectively.

In the second embodiment, the wire 132 is wound around the reel 113 of the drive unit 110 and the slider 135 is moved up and down. However, the present invention is not limited to this, and instead of using the wire 132, a resin rack 232 as a transmission member and The slider 135 may be moved up and down by the pinion 213.
As shown in FIG. 18, the guide portion 130 includes a guide rail 231 disposed between the rear frame 103 c and the trim member 105, and a slider 135 that is guided by the guide rail 231 and is movable along the guide rail 231. And a rack 232 that can be moved up and down while being guided by the guide rail 231 and that has an upper end connected to the slider 135. Instead of the reel 113, a pinion 213 that engages with the rack 232 is connected to the output side of the drive unit 110.
With such a configuration, when the drive unit 110 rotates forward and backward, the pinion 213 rotates forward and backward, and the rack 232 is guided by the guide rail 231 and moves up and down by the forward and reverse rotation. As a result, the slider 135 connected to the upper end of the rack 232 moves up and down, and the blind seat 121 connected to the slider 135 moves up and down.

In the second embodiment, the driving unit 110 winds the wire 132. However, the present invention is not limited to this, and as shown in FIG. 19, the driving unit 110 sends out the spiral cable 334 as shown in FIG. It is good. As in the second embodiment, the roll shade portion 122 is curved and disposed along the front frame 103a and the upper frame 103b.
The guide part 130 is provided in the rear frame 103c. The guide part 130 is disposed in the cable pipe 332, a guide rail 131, a slider 135 slidably guided by the guide rail 131, a hollow cable pipe 332 connected to the lower end of the guide rail 131. And a spiral cable 334 or the like as a transmission member that can slide inside. The left and right end portions of the free end of the blind sheet 121 are attached to the slider 135.
The cable pipe 332 is bent with a predetermined curvature in the vicinity of the lower end portion of the rear frame 103c, and extends forward (leftward). A cable pipe holder 333 is attached so as to hold the cable pipe 332 at the lower part of the window frame 103. Inside the cable pipe holder 333, the cable pipe 332 is partially cut in the length direction, and the spiral cable 334 is exposed at the cut portion.

The drive unit 110 includes an electric motor, a speed reduction mechanism unit, and the like, and is connected to the cable pipe holder 333. An output gear 313 is attached to the output side of the drive unit 110 so as to protrude to the side of the vehicle body. The output gear 313 is attached so as to mesh with the spiral cable 334 exposed in the cable pipe holder 333 described above. The spiral cable 334 and the mechanism of the drive unit 110 that meshes with the spiral cable 334 and sends out the spiral cable 334 are the same as in the first embodiment.
A spiral cable 334 is inserted into the guide groove of the guide rail 131 and slidably guides the slider 135 and the spiral cable 334 connected to the slider 135.

  Since the driving unit 110 and the guide unit 130 are configured as described above, when the driving unit 110 rotates forward and backward, the spiral cable 334 is guided in the cable pipe 332 and the guide rail 131 and is connected to the end of the spiral cable 334. The fixed slider 135 moves between the upper end portion and the lower end portion of the guide rail 131. Accordingly, the stretchable blind sheet 121 is stretched and stored between the upper side and the lower side of the opening 102a of the window frame 103 while expanding and contracting in the width direction.

  In the above embodiment, the side rods 23, the center rods 25, etc. constituting the rotating rods 22d of the roll shade portions 22, 122 are configured to have the same length in the axial direction. The lengths in the axial direction (longitudinal direction) of the side rod 23, the center rod 25, etc. may be varied according to the curvature of the part where the portions 22, 122 are arranged. That is, the shape of the edge of the front window where the roll shade portions 22 and 122 are disposed and the window frame of the door window are curved, and the curvature is not necessarily constant as a whole. Accordingly, the curvatures of the roll shade portions 22 and 122 differ depending on the positions in the axial direction.

FIG. 20 shows a modification of the roll shade unit 122 of the second embodiment. Since it is the same also about the roll shade part 22 demonstrated in Example 1, description is abbreviate | omitted. 20 is provided with a spring holder 22c at one end, and one end of the spring holder 22c is connected to a center rod 25 (25b) via a joint 24. A center shaft 22a and a coil spring 22b (not shown) are disposed inside the spring holder 22c. The lower end of the coil spring 22b is fixed to the spring holder 22c, and the upper end is fixed to the center shaft 22a. The coil shade 22b receives the rotational force in the winding direction.
In FIG. 20, the curvature of the center shaft 22a is set differently in the ranges R1 to R5 in the axial direction. That is, in the ranges R1 and R5, the curvature is small (that is, the radius of curvature is large), in R2 and R4, the curvature is medium (that is, the radius of curvature is medium), and in R3, the curvature is large (that is, the radius of curvature is small). It has become.

In accordance with the magnitude of the curvature, a center rod 25a (or side rod 23) having a long axial direction is used for the ranges R1 and R5 where the curvature is small, and an axial direction is used for the ranges R2 and R4 where the curvature is medium. A center rod 25b having a medium length is used, and a center rod 25c having a short axial length is used in a range R3 having a large curvature.
As described above, the center rod 25a (or the side rod 23) having a long axial direction, the center rod 25b, and the short center rod 25c are disposed in accordance with the R shape such as the window frame in which the roll shade portion 122 is disposed. Therefore, it is possible to easily adapt the roll shade portion 122 to an R shape such as a window frame. Thereby, when the center rod 25, the joint 24, and the side rod 23 rotate around the center shaft 22a, the resistance force is reduced, and the center rod 25, the side rod 23 can rotate without difficulty. Therefore, noise during operation is also reduced. Further, by using the center rod 25a having a long axial length, the number of parts can be reduced.

In FIG. 20, three types of center rods 25 (and side rods 23) are shown. However, the present invention is not limited to this, and two or more types of center rods 25 (and side rods 23) are used. Can do.
Further, by using only the center rod 25c having a short axial length instead of using the center rods 25a and 25b having a long axial length, the roll shade portion 122 can be smoothly adapted to be easily adapted to the curve. And it can be rotated with reduced noise.
In the example of FIG. 20, in order to facilitate the function of the joint 24 as a joint portion, the axial length is extremely short and constant, but not limited to this, a plurality of types of shafts are used in accordance with the curvature. Directional length joints 24 may be used.

In the above embodiment, for example, the joint 24 and the center rod 25 are connected to a rectangular engagement recess 24a formed in the joint 24 as shown in FIG. The engagement protrusions 25a having a shape were joined in a loosely fitted state.
The center rod 25 has two engaging protrusions 25a that are 180 degrees apart from each other in the circumferential direction (see FIG. 10), and the center rod 25 passes through the two engaging protrusions 25a and extends in the axial direction. It can be bent while sliding relative to the joint 24 in a plane. That is, in the drawing, the center rod 25 can be bent with respect to the joint 24 in a direction orthogonal to the Y direction.
The circumferential width of the engaging recess 24a is set to be larger by the gap A on one side in the circumferential direction than the circumferential width of the engaging protrusion 25a. With this gap A, the center rod 25 can be bent by a predetermined angle with respect to the joint 24 also in the Y direction in the drawing (a direction along a plane perpendicular to the plane). The larger the angle, the larger the angle of bending in the Y direction.

Since the curvature of the roll shade portions 22 and 122 is not constant depending on the position in the axial direction, it is necessary to appropriately set the size of the gap A according to the curvature. That is, the gap A may be set small in a portion where the curve is gentle, but the gap A may be set large in a portion where the curve is relatively steep so that the roll shade portions 22 and 122 can be adapted to a relatively steep curve. Need to be configured. By adjusting the gap A in this way, the curvature of the roll shade portions 22 and 122 can be set for each site in the axial direction.
Thus, since the center rod 25 can bend in the direction perpendicular to the Y direction and the Y direction within the plane with respect to the joint 24, the roll shade portions 22, 122 can smoothly rotate. It is.

However, since there is a gap A between the engagement protrusion 25a and the engagement recess 24a, the rotational force of the center rod 25 may be transmitted delayed by the gap A. Although this transmission delay has practically no effect on the stretching / storing operation, there is a possibility that a slight time difference may occur when compared at both ends of the roll shade portions 22 and 122. In addition, noise may occur due to the contact between the engagement protrusion 25a and the engagement recess 24a.
For this reason, in the modified example shown in FIG. 22, the engagement recess 24a and the engagement protrusion 25a are formed in a curved shape (R shape) instead of a rectangular shape so that the engagement recess 24a and the engagement protrusion 25a are always in contact with each other. . That is, when the joint 24 and the center rod 25 are linear in the axial direction, the engagement recess 24a and the engagement protrusion 25a are in contact at two points (point P). Further, even when bent in the Y direction, the engaging recess 24a and the engaging protrusion 25a abut at two points (point Q). Of course, even when it bends in a direction perpendicular to the Y direction, it makes contact at two points. In the example of FIG. 21, according to the rotation of the roll shade portions 22 and 122, the engaging recess 24a and the engaging protrusion 25a rotate while alternately repeating line contact, point contact, and separation.

In this way, the engaging recess 24a and the engaging protrusion 25a are always in contact even when bent in a straight line or in the Y direction. Therefore, when the center rod 25 rotates, the rotational force is directly transmitted without a rotation delay. It is transmitted to the joint 24. Further, the rotational force is directly transmitted to the center rod 25 that contacts the other end of the joint 24. Thereby, the rotation delay at the both ends of the roll shade portions 22 and 122 can be hardly caused.
In addition, since the engagement recess 24a and the engagement protrusion 25a abut against each other between the curved surfaces, rotation resistance, noise, and the like during operation are reduced, so that the rotation operation can be made smooth. Further, in the example of FIG. 22, the bending operation is smoother than the example of FIG. 21 because the curved surfaces can be bent while contacting with each other even in the Y direction. Therefore, the movement of the roll shade portion 22 as a whole is smoother.

Thus, in the modified example of FIG. 22, the engagement recess 24a and the engagement protrusion 25a can be held in contact with each other regardless of the curvature of curvature of the roll shade portions 22, 122. The mating recess 24a and the engaging protrusion 25a are formed in a curve. Therefore, the operation | work which sets the clearance gap A according to the curvature of the roll shade parts 22 and 122 as mentioned above does not generate | occur | produce.
When the engagement recess 24a and the engagement protrusion 25a are rectangular, the size of the gap A has to be set appropriately according to the curvature of the roll shade portions 22 and 122. There are many types. However, when the engagement recess 24a and the engagement protrusion 25a are curved (R-shaped), the engagement recess 24a and the engagement protrusion 25a have a constant shape regardless of the curvature of the roll shade portions 22 and 122. This is preferable because the types of the joint 24 and the center rod 25 do not increase.

  In the above embodiment, the drive unit 110 is disposed between the door trim 104 and the door panel 102. However, the present invention is not limited to this, and the end of the roll shade unit 122 is formed hollow to drive into this space. The portion 110 may be provided. In the case of the first embodiment, for example, when the driving unit 110 is disposed in the rear end portion of the roll shade portion 122, the pulley 133 is appropriately disposed and the wire 132 is disposed along the rear frame 103c. The wire can be routed to the lower portion of the guide rail 131, and the direction of the wire can be changed by a pulley so that the slider 135 can be pulled downward from here. It is also possible to dispose the drive unit 110 in the front end portion of the roll shade unit 122.

In the above embodiment, the blind sheet 121 is configured to cover substantially the entire region of the opening 102a when the blind sheet 121 is completely expanded. However, the present invention is not limited thereto, and the blind sheet 121 is completely expanded. When it becomes, you may comprise so that only the upper part of the opening part 102a may be covered. In this way, the function as a visor can be achieved.
In the above embodiment, the driving unit 110 and the guide unit 130 can be integrally formed as a module. This is preferable because it can be easily incorporated into the door. Furthermore, in addition to the drive part 110 and the guide part 130, the roll shade mechanism part 120 can also be formed as a unitary module.
In the above embodiment, the slider 135 is attached to the free end of the blind sheet 121, and the slider 135 is guided up and down along the guide rail 131 to expand and store the blind sheet 121. However, the blind sheet 121 may be directly moved up and down by attaching a wire to the right end of the free end of the blind sheet 121 and winding the wire around a reel by the drive unit.
