Description

  The present invention relates to a vehicle sunshade device. More specifically, the present invention relates to an improvement in the structure of a vehicle sunshade device provided on a roof of a vehicle or the like.

  In recent years, vehicles equipped with sunshades that block large-opening sunroofs made of large single glass have gained popularity. As a sunshade device in this case, for example, a device including a sunshade supported under a transparent glass roof so as to be slidable in the front-rear direction of the vehicle is known.

  As such a sunshade device, there is conventionally known a device provided with a lock mechanism at the front edge portion of the sunshade so that the lock mechanism can be locked by being hooked to the opening when fully closed (see, for example, Patent Document 1). . If the user slides the sunshade to the fully closed position, the user can activate the lock mechanism to be in the locked state. When opening the sunshade in the locked state, the unlocked state is first manually released, and then the sunshade is slid in the reverse direction.

Furthermore, as such a sunshade, a front shade that can be pulled out in the rear direction of the vehicle and a rear shade that can be pulled out in the front direction of the vehicle are provided, and the ends of both shades can be brought into contact with each other. There is also.

  However, as described above, the apparatus having the two shades that can be matched cannot realize the following operation. That is, for example, when one of the shades is an electric type and the other is a manual type, the lock mechanism is selectively switched between the locked state and the unlocked state only by the operation of the electric shade. However, it is difficult to realize the operations such as moving them together or moving only the electric shade. Such an operation can be realized by using, for example, an electromagnetic lock device as a lock mechanism. However, if this is done, the structure of the drive unit becomes complicated, which is a preferable means in terms of high costs and an increase in the size of the device. I don't get it.

  Therefore, the present invention selectively switches between the locked state and the unlocked state of the lock mechanism of the shade only by operating the electric shade, moves the manual shade together with the electric shade, or the electric type It is an object of the present invention to provide a vehicle sunshade device capable of realizing operations such as moving only a shade without incurring high costs or increasing the size.

In order to solve this problem, the present invention provides a vehicle sunshade device having a shade that is slidable in a closing direction and an opening direction opposite to the light-transmitting member that is provided on the roof portion of the vehicle and forms a light-transmitting area. A pair of guide rails that guide the slide of the shade, a motor that opens and closes the shade, and a lock mechanism that keeps the shade locked in a state where the shade blocks the translucent member. , der those with unlocking means for unlocking by further sliding the shade of the lock state to the closing direction is, the shade comprises a plurality of shades shade end each other abut against each other, the locking mechanism, they The shade ends are locked to keep the translucent member in a blocked state. The shade end is provided with a slide bar whose end in the extending direction is slidably supported with respect to the guide rail, and the lock mechanism is between the guide rails and above the slide bar. provided is characterized in Rukoto.

In such a vehicle sunshade device, when the shade is closed and the translucent member is blocked, the lock mechanism is locked so that the shade is not opened. At this time, when the shade is further slid in the closing direction, the locked state is released by the unlocking means. For example, if the shade is an electric type that is opened and closed by a motor, the locked state is automatically released if it is electrically slid in the closing direction, so that the shade can be slid in the opening direction. It becomes a state. According to this, for example, when one of the shades is an electric type and the other is a manual type, it is possible to selectively switch between the locked state and the unlocked state of the lock mechanism only by operating the electric shade. Further, when the electric shade is slid in the closing direction and is brought into contact with the other shade, the lock mechanism can be operated to be in the locked state. If the electric shade is slid electrically in such a state, the locked manual shade can be moved together with the shade. Further, according to the present invention, since such a sunshade device is realized by a mechanical mechanism without using an electromagnetic lock device, there is an advantage that it is easy to achieve compactness, weight reduction, and cost reduction. Alternatively, the shade in the sunshade device may be composed of a plurality of shades where the shade ends abut against each other, and the lock mechanism may be configured to lock the shade ends and keep the translucent member blocked. For example, it is a combination of an electric shade that is opened and closed by a motor and a manual shade. In this case, if the electric shade and the manual shade are brought into contact with each other and the electric shade is operated in a locked state, the other manual shade can be pulled and slid. Further, once the locked electric shade is slid in the closing direction and then slid in the opening direction, the lock can be released and only the electric sunshade can be operated.

  Here, the locking mechanism according to the present invention includes at least a locking member formed to be rotatable, a locked member that is locked by the locking member to form a locked state, and a rotation of the locking member. And a stopper for restricting the operation within a predetermined range. The locking member can rotate within a range restricted by the stopper, and is locked by being locked to the locked member.

  The unlocking means according to the present invention is constituted by an unlocking guide for guiding the locking member to a position where it is disengaged from the locked member as the shade slides in the closing direction. In this case, the locking member is guided by the unlocking guide and is released from the locked member by rotating or the like.

  Alternatively, the unlocking means may be constituted by an unlocking spring that biases the locking member so as to be detached from the locked member when the shade slides in the closing direction. When the shade is slid in the closing direction, the locking member biased by the unlocking spring is released from the locked member and releases the locked state.

  The vehicle sunshade device may be a combination of an electric shade that is opened and closed by a motor and a manual shade. The plurality of shades in the vehicle sunshade device may have different light shielding rates.

  According to the vehicle sunshade device of the present invention, the lock mechanism is selectively switched between the locked state and the unlocked state only by operating the electric sunshade, and the manual sunshade is moved together with the electric sunshade. Alternatively, it is possible to realize an operation such as moving only the electric sunshade without incurring high cost and large size.

  Hereinafter, the configuration of the present invention will be described in detail based on an example of an embodiment shown in the drawings.

  1 to 14 show an embodiment of a vehicle sunshade device according to the present invention. The vehicle sunshade device 1 according to the present invention is a device with a dimming function provided, for example, in a roof portion of a vehicle or the like, and is capable of dimming the inside of the vehicle by operating the sunshade. Furthermore, the vehicle sunshade device 1 according to the present invention also includes a lock mechanism that keeps the shade locked in a state where the sunshade blocks the light transmitting member. In the following, when such a vehicle sunshade device 1 is applied to a so-called sunroof in a passenger car or the like, the entire device 1 will be described first, and a lock mechanism and the like will also be described. In the present embodiment, the traveling direction (front direction of the driver) of the vehicle is referred to as front (front side), and the reverse direction is referred to as rear (rear side).

  The vehicle sunshade device 1 according to the present embodiment is pulled out from the vicinity of the front portion of, for example, a glass translucent member (hereinafter also referred to as a glass roof) 4 provided on the roof portion of a passenger car to form a translucent area. A manually operated front roll shade 5 that can be provided, a motorized rear roll shade 8 that has a different light shielding rate from the front roll shade 5 and that can be pulled forward from the vicinity of the rear portion of the glass roof 4, and the front A front roller 2 for winding the roll shade 5 and a rear roller 3 for winding the rear roll shade 8 are provided.

  The glass roof 4 described above is fitted and fixed in the opening 9a of the roof panel 9 constituting the roof portion of the vehicle in the present embodiment to form a non-openable sunroof (see FIG. 2 and the like). Although not particularly illustrated, a portion other than the glass roof 4 (roof headlining) in the vehicle interior ceiling of the vehicle is a molded ceiling in which a knit or the like is used for the skin. In the present embodiment, the front portion of the glass roof 4 among the ceiling with the roof head lining is referred to as a front roof head and the rear portion is referred to as a rear roof head, which are denoted by reference numerals 9f and 9r (FIG. 3 and the like). reference). In the vehicle according to this embodiment, the opening 9a of the roof panel 9 is not provided with a cross beam (so-called roof panel reinforcement).

  The roll shade is a screen for blocking the inner surface of the glass roof 4 (the surface on the vehicle interior side). In the present embodiment, a manually operated front roll shade 5 that can be pulled out from the vicinity of the front portion of the glass roof 4 to the rear, and an electric type that can be pulled out from the vicinity of the rear portion of the glass roof 4 to the front. A set of shades called rear roll shades 8 is arranged (see FIG. 3 and the like). These roll shades 5 and 8 are made of, for example, cloth or canvas, and can be wound by rollers (winding devices) 2 and 3.

  In addition, a front slide bar 6 and a rear slide bar 7 constituting a shade end are provided on the rear edge of the front roll shade 5 and the front edge of the rear roll shade 8, respectively (see FIG. 2 and the like). The front slide bar 6 and the rear slide bar 7 are so-called support bars provided at the leading ends of the front roll shade 5 and the rear roll shade 8, respectively, and constitute a part of the roll shades 5 and 8. The slide bars 6 and 7 move in the front-rear direction along the guide rail 10, and the roll shades 5 and 8 are pulled out evenly in the width direction, or sent to the rollers 2 and 3 to be rewound evenly (FIG. 4). Etc.).

  The rollers 2 and 3 wind up the roll shades 5 and 8 described above, and a front roller 2 that winds up the front roll shade 5 and a rear roller 3 that winds up the rear roll shade 8 are provided (see FIG. 3 and the like). ). For example, in the present embodiment, the front roller 2 is provided between the glass roof 4 and the front roof head 9f slightly ahead of the opening (translucent area made of the glass roof 4) 9a. Similarly, a rear roller 3 is provided slightly behind the opening 9a and between the glass roof 4 and the rear roof head 9r (see FIG. 4 and the like). The front roller 2 and the rear roller 3 are urged so as to rotate in the winding direction of the front roll shade 5 and the rear roll shade 8 by a coil spring (not shown), for example.

  Further, guide rails 10 for guiding the front slide bar 6 and the rear slide bar 7 are provided on both sides of the opening (translucent area) 9a of the roof panel 9 (see FIG. 1). Although not shown in detail in detail, each of the left and right guide rails 10 in this embodiment can accurately guide both ends of the front slide bar 6 and both ends of the rear slide bar 7 in a state where it is difficult to come off, for example, having a cross-sectional channel shape. It is formed as follows.

  The geared cable 11 is connected to the rear slide bar 7 and is provided as a member (transmission cable) for transmitting the driving force of the motor 13 to the rear slide bar 7. The geared cable 11 of the present embodiment has a total of two pairs arranged at both ends of the rear slide bar 7 and is arranged so that both ends of the rear slide bar 7 are simultaneously moved forward or backward by the same amount. (See FIG. 1). A pair of left and right geared cables 11 connected to the rear slide bar 7 are connected to a pinion 13 a of a motor 13 disposed behind the glass roof 4. Further, at least a portion of the geared cable 11 that meshes with the pinion 13a of the motor 13 is provided with teeth and has a rack shape. Furthermore, cable guides 14 for guiding the geared cable 11 are provided on the left and right sides of the motor 13 (see FIG. 1).

  The motor 13 generates a driving force for moving the rear slide bar 7 in the front-rear direction, and is disposed behind the glass roof 4 as described above (see FIG. 1). When the pinion 13a of the motor 13 is rotated in one direction (counterclockwise direction in FIG. 1), the left and right geared cables 11 are fed forward, and the rear slide bar 7 slides forward (see FIG. 1, etc.). ). By this operation, the rear roll shade 8 can be sent out by a desired amount to block the glass roof 4. Further, the rear slide bar 7 can be stopped at a desired position by stopping the motor 13. Since the rear roll shade 8 is always pulled in the winding direction by the rear roller 3 as described above, the rear roll shade 8 is in a tensioned state during both operation and stop.

  Further, although not particularly shown, the vehicle of the present embodiment is provided with a switch for driving the motor 13. The switch in this case is preferably capable of driving the motor 13 independently and switching between forward rotation and reverse rotation. For example, in this embodiment, a seesaw switch for driving the motor 13 is arranged. In such a case, an input device that is easy to use for the user can be configured by matching the direction in which the seesaw switch is tilted with the direction in which the rear roll shade 8 moves. Note that these switches may be arranged at positions where the driver can easily operate, or may be arranged at positions where the passengers in the rear seat can operate.

  Here, it is preferable that the front roll shade 5 and the rear roll shade 8 described above are made of materials having different light shielding rates. In such a case, it is possible to finely adjust the amount of light inserted into the vehicle by appropriately changing the pull-out amount of the front roll shade 5 and the pull-out amount of the rear roll shade 8. For example, in the present embodiment, the front roll shade 5 is a shade made of a material having a relatively low light shielding rate (for example, a light shielding rate of 30%), and the rear roll shade 8 is a shade made of a material having a high light shielding rate (for example, a light shielding rate of 100%). Two types are to be used. In such a case, for example, a desired light-blocking state (a state in which a desired amount of light is inserted) can be obtained depending on the situation, such as a state in which a lot of light is inserted into the driver's seat or the passenger seat while the rear seat is shielded. Further, if the rear roll shade 8 is pulled out to block all of the glass roof 4, light can be prevented from being inserted from the opening 9a.

  In addition, reducing the light shielding rate of the front roll shade 5 as described above has the following advantages. That is, since a material such as a cloth thinner than the rear roll shade 8 can be used as the shade having a low light shielding rate, a space (winding capacity) required for winding the front roll shade 5 by the front roller 2 is suppressed. be able to. In general, a sun visor, header box, front personal lamp (map lamp), etc. are often arranged on the ceiling of the front seat side of the vehicle. In this regard, a relatively thin ground front roll shade 5 is adopted. In the case of the present embodiment, it is effective because the winding capacity between the glass roof 4 and the front roof head 9f can be suppressed to save space.

  Moreover, the guide rail 10 of this embodiment serves as a guide of the front roll shade 5 (the front slide bar 6) and the guide of the rear roll shade 8 (the rear slide bar 7). More specifically, both the roll shades 5 and 8 are guided by a pair of guide rails 10 arranged one by one on the left and right (see FIG. 1 and the like). In such a case, it is preferable in that the number of members is small and the guide can be saved in space. That is, if each of the front roll shade 5 and the rear roll shade 8 is individually guided, the guide rail has a two-stage structure, and an additional installation space is required as much as it overlaps vertically, but the number of members also increases. In this case, since both the roll shades 5 and 8 are guided by the left and right guide rails 10, the installation space can be reduced. In other words, the vehicle sunshade device 1 of the present embodiment has a structure in which both the roll shades 5 and 8 are slid without overlapping each other in approximately the same plane (or curved surface), and the front roof head 9f or the rear roof head. The space between 9r and the glass roof 4 can be made thin.

  Further, in the present embodiment, a lock mechanism 12 is provided on the front slide bar 6 and the rear slide bar 7 that face each other (see FIG. 1). The lock mechanism 12 maintains the roll shades 5 and 8 in a locked state with the front roll shade 5 and the rear roll shade 8 blocking the glass roof 4. Further, the lock mechanism 12 of the present embodiment unlocks the lock by releasing one of the locked shades 5 and 8 in the closing direction (the direction in which the roll shades 5 and 8 are pulled out). The automatic release mechanism) 17 is also provided. A specific example of such a locking mechanism 12 will be described as follows.

<First form>
For example, the lock mechanism 12 of this embodiment shown in FIG. 11 includes a locking member 15 that is formed to be rotatable, a locked member 16 that is locked by the locking member 15, and a locked state. An unlocking means 17 and a stopper 18 for restricting the rotation of the locking member 15 within a predetermined range are provided. Of these, the locking member 15 and the unlocking means 17 are centered on a fulcrum 19. As shown in FIG. 11, the locking plate 20 is rotatable in the left-right direction. The locking plate 20 and the locked member 16 may be provided on either the front roll shade 5 or the rear roll shade 8, but for example, the rear slide bar 7 of the rear roll shade 8 that is electrically driven in this embodiment. These locking plates 20 are provided, and one locked member 16 is provided on the front slide bar 6 of the front roll shade 5 (see FIG. 11).

  The locking plate 20 is rotatable about a fulcrum 19 and is further biased by a tension coil spring 23. The tension coil spring 23 is arranged so that one end 23a and the other end 23b sandwich the fulcrum 19, and the tension coil spring 23 extends most when it overlaps the fulcrum 19 (see FIG. 11). The locking plate 20 is urged clockwise or counterclockwise with the position where the tension coil spring 23 is extended most in this way.

  In the vicinity of the locking plate 20, for example, a protrusion-shaped stopper 18 is provided that restricts the range in which the locking plate 20 can be rotated (turned) (see FIG. 11). The stopper 18 of the present embodiment causes the locking plate 20 to stand by in a state where the locking member 15 can be locked to the locked member 16 (a lockable state).

  The locking member 15 is formed of a hook-shaped protrusion, and can be hooked on a pin-shaped locked member (lock pin) 16 having a head 16a for retaining. The locking member 15 can rotate within a range restricted by the stopper 18 described above, and is locked to the locked member 16 to be locked. The locked member 16 is formed, for example, on a locked plate 24 provided on the front slide bar 6 (see FIG. 11).

  The unlocking means 17 is, for example, an unlocking guide 17a that guides the locked member 16 to a position where it is disengaged from the locking member 15 as the rear roll shade 8 (or the front roll shade 5) slides in the closing direction. It is configured (see FIG. 11). The unlocking guide 17a of the present embodiment is formed with an inclined linear or curved side edge and abuts on the locked member 16 to rotate the locking plate 20 counterclockwise in the figure.

  The locking plate 20 is provided with a return projection 21 and the locked plate 24 is provided with a reverse pin 22 (see FIG. 11). The return protrusion 21 and the reverse pin 22 are for automatically returning the locking plate 20 (and its locking member 15), which has been unlocked by the unlocking means 17, to a lockable state again. . The return protrusion 21 is formed so as to protrude obliquely. For example, when the rear roll shade 8 is slid in the opening direction (the direction in which the rear roll shade 8 is wound up), the return protrusion 21 comes into contact with the reverse pin 22 for locking. The plate 20 is rotated clockwise in the figure.

  The lock mechanism 12 configured as described above operates as follows. That is, for example, when the rear roll shade 8 is slid in the closing direction while waiting in a lockable state as shown in FIG. 11, the oblique side 20a of the locking plate 20 and the locked member 16 come into contact with each other. When the rear roll shade 8 is further slid in this state, the locking plate 20 is pushed by the locked member 16 and rotates counterclockwise. When the locking member 15 exceeds the locked member 16, it is pulled. The coil spring 23 is rotated clockwise by the urging force of the coil spring 23. As a result, the locking member 15 is locked to the locked member 16 to be locked. When the lock mechanism 12 is locked in this way, the roll shades 5 and 8 cannot be opened. For example, if the electric rear roll shade 8 is slid rearward, the locked front roll shade 5 is also slid rearward together.

  In order to release the lock state of the lock mechanism 12, first, the rear roll shade 8 (or the front roll shade 5) is further slid in the closing direction. Then, the locked member 16 in contact with the unlocking guide 17a of the locking plate 20 gradually rotates the locking plate 20 counterclockwise. When the locking plate 20 further rotates beyond the most extended state of the tension coil spring 23, it is urged counterclockwise by the tension coil spring 23 to bring the side 20b into contact with the reverse pin 22. Stop. By such an operation of the locking plate 20, the locking member 15 is released from the locked member 16 to be unlocked, and the rear roll shade 8 and the front roll shade 5 can be slid in the opening direction. Become. For example, when the rear roll shade 8 is slid in the opening direction, the reverse pin 22 in contact with the return protrusion 21 presses the locking plate 20 so as to rotate in the clockwise direction. When the locking plate 20 is further rotated beyond the most extended state of the tension coil spring 23, the locking coil spring 23 is urged clockwise by the tension coil spring 23 and stops in contact with the stopper 18. It waits in the state (lockable state) in which the member 15 can be locked to the locked member 16.

<Second form>
The locking mechanism 12 shown in FIG. 12 has a locking hook 20 ′ that can be turned right and left and that can move the locking member 15 at the tip up and down, a locked member 16 that is a long hole, And locking means 17 (see FIG. 12).

  The locking hook 20 ′ is a member that can rotate left and right around the fulcrum 19 on the support base 27 and can move the tip up and down around another fulcrum 25. A support base 27 that supports the locking hook 20 ′ is attached to the rear slide bar 7 of the rear roll shade 8, for example. The urging means (23) as described above is not provided for the locking hook 20 ', and is configured to be lowered by its own weight. In addition, a part of the support 27 that contacts the lower surface of the locking hook 20 ′ and holds the locking hook 20 ′ substantially horizontally functions as the stopper 18 (see FIG. 12).

  The locking member 15 is formed of a downward projection formed in a hook shape, and can be hooked on the locked member 16 formed of an edge of a long hole. Moreover, the back side of the hook-shaped tip is an inclined surface. The locking member 15 can move up and down within the range restricted by the stopper 18 described above, and is locked to the locked member 16 to be locked. The locked member 16 is formed, for example, on a locked plate 24 provided on the front slide bar 6 (see FIG. 12).

  The unlocking means 17 is, for example, an unlocking guide 17a that guides the locking member 15 to a position disengaged from the locked member 16 as the rear roll shade 8 (or the front roll shade 5) slides in the closing direction. It is configured (see FIG. 12). The unlocking guide 17a of this embodiment is formed by an oblique wall surface formed on the locked plate 24, and rotates the locking hook 20 'counterclockwise in the figure.

  A reverse guide 26 is provided on the locked plate 24. The reverse guide 26 is composed of an oblique wall surface provided so as to face the above-described unlocking guide 17a. For example, when the rear roll shade 8 is slid in the opening direction, the reverse guide 26 abuts on the unlocking guide 17a and counterclockwise. The locking hook 20 ′ rotated around is rotated clockwise to return to the original lockable state.

  Further, a trapezoidal protrusion 28 is formed at substantially the center of the locked plate 24 (see FIG. 12). A path 29 for guiding the tip of the locking hook 20 ′ (locking member 15) around the periphery is formed by the base protrusion 28. The trapezoidal projection 28 is formed so that its height is lower than the thickness of the hook portion of the locking portion 15 so as not to hinder the movement of the locking hook 20 ′.

  The lock mechanism 12 configured as described above operates as follows. That is, as shown in FIG. 12, for example, when the rear roll shade 8 is slid in the closing direction while waiting to be locked, the locking member 15 is placed on the locked plate 24 and slid to be covered. When the locking member 16 is reached, the hook-shaped tip is fitted into the locked member 16 and is locked. When the lock mechanism 12 is locked in this way, the roll shades 5 and 8 cannot be opened. For example, if the electric rear roll shade 8 is slid rearward, the locked front roll shade 5 is also slid rearward together.

  In order to release the lock state of the lock mechanism 12, first, the rear roll shade 8 (or the front roll shade 5) is further slid in the closing direction. Then, the inclined back surface of the hook-shaped tip portion of the locking member 15 is pressed against the edge of the locked member (long hole) 16, and the hook-shaped tip portion is pushed up by the thickness and detached from the locked member 16. . When the rear roll shade 8 is further slid, the locking hook 20 ′ whose tip is in contact with the unlocking guide 17 a of the locked plate 24 is guided counterclockwise by the unlocking guide 17 a. Rotate to. By such an operation of the locking hook 20 ′, the locking member 15 is released from the locked member 16 to be unlocked, and the rear roll shade 8 and the front roll shade 5 can be slid in the opening direction, respectively. It becomes. For example, when the rear roll shade 8 is slid in the opening direction, the locking member 15 in contact with the reverse guide 26 is guided along the reverse guide 26 and rotates the locking hook 20 ′ in the clockwise direction. By such an operation, the locking hook 20 ′ returns to the standby position in a state where the locking member 15 can be locked to the locked member 16 (lockable state).

<Third embodiment>
The locking mechanism 12 shown in FIGS. 13 and 14 includes a locking member 15 formed to be rotatable, a locked member 16 that is locked by the locking member 15, and an unlocking state. Means 17 and a stopper 18 for restricting the rotation of the locking member 15 within a predetermined range are provided. The locking member 15 is supported at the tip of the locking plate 20, and the locking plate 20 and the stopper 18 are provided on a support base 27.

  The locking plate 20 is rotatable about a fulcrum 19 and is further biased counterclockwise in the figure by an unlocking spring 17b made of a tension coil spring. One end 17 c of the unlocking spring 17 b is connected to the locking plate 20, and the other end 17 d is connected to the support base 27.

  In the vicinity of the fulcrum 19, for example, in the vicinity of the locking plate 20, a protruding stopper 18 that restricts the range in which the locking plate 20 can be rotated (turned) is provided (see FIG. 13). The stopper 18 of the present embodiment is also provided so that the locking plate 20 waits in a state where the locking member 15 can be locked to the locked member 16 (lockable state).

  The locking member 15 is a downward projection provided at the front end of the locking plate 20 and has a large lower end portion (see FIGS. 13 and 14). The locking member 15 (and the locking plate 20) can rotate within the range restricted by the stopper 18 described above, and is locked to the locked member 16 to be locked.

  The locked member 16 is formed on the locked plate 24 so that the locking member 15 is locked and the lock mechanism 12 is locked. For example, the locked member 16 of the present embodiment is configured by only the locking block 16 a provided on the locked plate 24 or a combination of the block 16 a and the guide lever 30. The block 16a is provided on the locked plate 24 at a position where the locking member 15 can be locked.

  The guide lever 30 is a member that guides the locking member 15 to a locking position with respect to the locked member 16, and is configured by a flap-shaped lever that can rotate around a fulcrum 32, for example. The guide lever 30 is urged, for example, in the clockwise direction in the figure by a torsion coil spring 31 disposed at a fulcrum 32. The guide lever 30 of the present embodiment has its rotatable range restricted by the adjacent block 16a and cannot rotate in the clockwise direction as compared with the state shown in FIG. 13 (the state in contact with the block 16a). . Further, the edge of the guide lever 30 facing the support base 27 is a gently inclined guide 30a for guiding the locking member 15 toward the locked member 16 (see FIG. 13).

  The unlocking means 17 guides the locking member 15 to be detached from the locked member 16 as the rear roll shade 8 (or the front roll shade 5) slides in the closing direction, for example. For example, the unlocking means 17 of the present embodiment is configured by an unlocking spring 17b that urges the locking plate 20 so that the slidable locking member 15 is detached from the block 16a.

  The lock mechanism 12 configured as described above operates as follows. That is, to release the locked state shown in FIG. 13, first, the rear roll shade 8 (or the front roll shade 5) is further slid in the closing direction. When the locking member 15 slides to the tip of the block 16a, it moves over the block 16a to the opposite side due to the urging force of the unlocking spring 17b (see the arrow in the figure). By such an operation, the locking member 15 is released from the locked member 16 and is unlocked, and the rear roll shade 8 and the front roll shade 5 can be slid in the opening direction. In this state, when the rear roll shade 8 or the front roll shade 5 is slid in the opening direction, the locking member 15 comes into contact with the guide lever 30, and when the locking member 15 is further slid, the guide lever 30 is counterclockwise. It rotates around and retracts to the extent that the locking member 15 can pass. Further, in the unlocked state, the locking plate 20 stops in contact with the stopper 18 and waits in a state where the locking member 15 can be locked to the locked member 16 (lockable state). .

  On the other hand, when the lock mechanism 12 is waiting in a lockable state, for example, when the rear roll shade 8 is slid in the closing direction, the locking member 15 comes into contact with the inclined guide 30 a of the guide lever 30. When the rear roll shade 8 is further slid in this state, the locking member 15 is guided to wrap around the guide 30a, and the locking plate 20 rotates clockwise according to this movement. The locking member 15 that has passed over the vicinity of the fulcrum 32 of the guide lever 30 is locked to the locked member 16 by the urging force of the unlocking spring 17b (see FIG. 13).

  As is clear from the above description, according to the vehicle sunshade device 1 of this embodiment described with a specific configuration, for example, when the rear roll shade 8 is an electric type that is opened and closed by the motor 13, the locked state Since the locked state is automatically released by electrically sliding the rear roll shade 8 in the closing direction, the shade 8 can be slid in the opening direction. According to this, for example, when one of the roll shades 5 and 8 is electrically operated and the other is manually operated as in the present embodiment, the locked state and unlocking of the lock mechanism 12 are performed only by operating the electrically operated roll shade 8. It is possible to selectively switch between states. Further, if the electric roll shade 8 is slid in the closing direction and abutted against the other roll shade 5, the lock mechanism 12 can be operated to be in a locked state. In such a state, the electric roll shade 8 is If it is electrically slid, the locked manual roll shade 5 can be moved together with it. In particular, when the rear roll shade 8 is an electric type as in this embodiment, it is preferable in that the front and rear shades 5 and 8 can be operated even from the driver's seat, for example. Moreover, since the lock mechanism 12 of this embodiment is configured by a mechanical mechanism without using an electromagnetic lock device or the like, there is an advantage that it is easy to achieve compactness, weight reduction, and cost reduction.

  In the above-described embodiment, the description has been mainly made of sliding the electric rear roll shade 8 as the operation when shifting to the locked state or the unlocked state. However, the manual type front roll shade 5 is slid. The same is true in the case of the case. That is, since the locking mechanism 12 of this embodiment operates by changing the relative positions of the locking member 15 and the locked member 16, for example, only when the electric rear roll shade 8 is slid. In addition, when the manual front roll shade 5 is slid (and when both roll shades 5 and 8 are slid simultaneously), the lock mechanism 12 is operated to switch between the locked state and the unlocked state. Is possible.

  Further, according to the vehicle sunshade device 1 of the present embodiment, the user can adjust the light by pulling the front roll shade 5 and the rear roll shade 8 to their favorite positions according to various situations. That is, for example, the rear roll shade 8 having a light blocking rate of 100% can be pulled out to a desired position to block a part of the sunlight (see FIG. 5), or can be completely pulled out to block the sunlight completely (FIG. 6). reference). Further, the rear roll shade 8 described above and the front roll shade 5 having a light shielding rate of 30%, for example, can be pulled out as much as desired so as to be in a desired light shielding state according to sunlight, temperature, or the like. At this time, an area blocked by the front roll shade 5, an area not blocked by the shade, and an area blocked by the rear roll shade 8 may be formed (see FIG. 7), or the front roll shade. 5 and the rear roll shade 8 may completely block the glass roof 4 (see FIG. 8). Note that when the glass roll 4 is blocked by the front roll shade 5 and the rear roll shade 8, the above-described lock mechanism 12 is in a locked state, and the front slide bar 6 and the rear slide bar 7 are joined. (See FIG. 8). In this state, for example, if the rear roll shade 8 that is electrically driven is slid, the front roll shade 5 (for example, manual type) 5 that is in the locked state can be pulled and simultaneously slid. Furthermore, for example, the rear shade 8 having a light blocking rate of 30% can be pulled out to a desired position to block out the sunlight appropriately (see FIG. 9), or the entire roll shade 8 can be pulled out to block out the entire sun appropriately. (See FIG. 10).

  In addition, according to the vehicle sunshade device 1 of the present embodiment in which a shade having a low light shielding rate is adopted for the front roll shade 5, the light shielding state in consideration of both the front seat occupant (particularly the driver) and the rear seat occupant. There is an advantage that it is easy to make. For example, when a child is sleeping in the back seat, the sun can be completely blocked by the rear roll shade 8 to make it easy to sleep. In addition, the front roll shade 5 can moderate the sun to the front seat appropriately, thereby reducing dazzling and heat while maintaining a feeling of openness and brightness, thereby making it possible to provide a comfortable environment for the driver to easily drive.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in the present embodiment, manual or electric roll shades 5 and 8 have been described as slidable shades, but this is only one form of the shade, and in addition, a so-called hard shell such as a hard shell is also shown. Even when a board-type shade is employed, the present invention can be applied regardless of the light shielding rate.

  In the above-described embodiment, the lock mechanism 12 having a form in which a pair of shades are directly joined and locked is described. However, this is also only a preferred embodiment of the present invention. For example, when a single shade is provided, one of the lock mechanisms 12 (for example, the locking member 15) may be provided on the shade, and the other (for example, the locked member 16) may be provided on the roof panel 9. . In the case of such a structure, the shade in a state where the glass roof 4 is blocked is locked by being locked to the roof panel 9 by the action of the lock mechanism 12, and the shade is opened due to the impact of, for example, traveling of the vehicle. Can be avoided.

  Furthermore, although the case where only a single lock mechanism 12 is installed has been described in the present embodiment (see FIG. 1), for example, a sunshade device such as two lock mechanisms 12 having the same configuration arranged side by side in the vehicle width direction. It is also possible to install a plurality of locking mechanisms 12 in one.

  Moreover, although glass roof 4 was illustrated in embodiment mentioned above, this is only a specific example of a translucent member, and even if it is a translucent roof which consists of materials (materials) other than glass, this invention is applied. Of course it is possible.
