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.

  2. Description of the Related Art Conventionally, a vehicle (particularly a passenger car) with a sunroof capable of dimming a part of the roof using glass is known. In recent years, a so-called large-aperture dimming roof in which the roof is a large single glass and the single glass is combined with a vehicle sunshade device has gained popularity.

As such a vehicle sunshade device, for example, a device including a sunshade supported so as to be slidable in the vehicle longitudinal direction under a transparent glass roof is known (for example, see Patent Document 1). The sunshade may be provided, for example, on a cross beam (roof panel reinforcement) crossing the glass roof portion. There is also a sunshade device in which a movable filter and a sunshade are arranged one above the other so that they can be opened and closed independently (see, for example, Patent Document 2).
JP 2001-301465 A JP 2002-52931 A

  However, the above-described vehicle sunshade device has the following problems. That is, the first problem is that the horizontal beam that can accommodate the sunshade takes up space in the area of the glass roof, so that the scenery and sunlight from the glass roof are blocked. For example, in the case of Patent Document 1, even if both of the sunshades provided before and after the horizontal beam are fully opened, the horizontal beam remains in the center of the glass roof. It will be damaged. Second, for example, even if a plurality of sunshades are provided as described above, it may be difficult or limited to freely adjust the degree of light inserted into the vehicle (light control). Third, since the space efficiency under the glass roof is not good, the ceiling height (indoor height) may be felt low.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle sunshade device that does not impair the feeling of opening, is easy to perform dimming, and is easy to secure the indoor height.

  In order to solve this problem, the present inventor has made various studies. First of all, if a large-opening sunroof that eliminates the cross beams installed below the glass roof is constructed, it will naturally not block the scenery and sunlight, and will not impair the feeling of opening when fully opened. However, if such a large glass area is covered with a sunshade, the storage space for the shade becomes very large or thick, which may be undesirable in terms of ensuring the strength of the roof and ensuring the indoor height. The inventor who has focused on the above points has further studied from the viewpoint of storage space and the adjustment of the amount of light to be inserted into the vehicle, and has obtained knowledge that leads to the solution of such problems.

  The present invention is based on such knowledge, and includes a sunshade device for a vehicle having a sunshade that is provided on a roof portion of the vehicle and that can be slid in a closing direction that blocks a light-transmitting member that forms a light-transmitting area and an opening direction that is opposite thereto. The sunshade includes a first shade and a second shade that are slidable in a closing direction that blocks the light-transmitting member and an opening direction that is opposite thereto, and the first shade and the second shade slide on the same surface. The first shade and the second shade are each provided with a lock device capable of engaging and disengaging the first shade and the second shade. It is characterized by having.

  The vehicle sunshade device according to the present invention has a structure in which the outer peripheral portion of a translucent member such as glass is supported by, for example, a roof panel having a frame-like opening, and therefore a horizontal beam is installed below the translucent member. It is possible to construct a large opening type translucent area, and the landscape and the sun are not blocked by the cross beam when the shade is fully opened. For this reason, a feeling of opening especially at the time of full opening as a sunroof is not spoiled.

  Further, in the present invention, a plurality of (for example, two) shades are provided at the same height so as to be able to face each other, and the shades are configured to be openable and closable. Is possible. For this reason, it is easy to secure the ceiling height (indoor height) in the vehicle by improving the space efficiency below the translucent member.

  In addition, since this vehicle sunshade device allows the first shade and the second shade to be engaged and disengaged by the locking device, for example, the first shade in the locked state brings the second shade together. It is also possible to slide. For example, when one shade is electric and the other is manual, it is possible to operate the manual shade by operating only the electric shade by using such a locking device.

  The locking device in such a vehicle sunshade device is a lock mechanism that maintains the shade locked in a state where the shade blocks the light-transmitting member, and further locks the shade in the locked state by further sliding in the closing direction. It is preferable to provide an unlocking mechanism for releasing. According to this locking mechanism, when the shade is further slid in the closing direction in the locked state, 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. Therefore, 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 a locked state and an unlocked state of the lock mechanism only by operating the electric shade. Furthermore, if the electric shade is electrically slid in the locked state, the locked manual shade can be slid along with it.

  Moreover, in the vehicle sunshade device of the present invention, at least one of the plurality of shades is an electric type, and at least the other one is a manual type. At least one of the plurality of shades may be a shade made of a hard board.

  Further, the vehicle sunshade device according to the present invention includes a front roll shade provided so that it can be pulled out rearward from the vicinity of the front portion of the translucent member, and a light shielding rate different from that of the front roll shade, and near the rear portion of the translucent member. A rear roll shade provided so as to be able to be pulled out from the front, a pre-winding device that winds up the front roll shade, and a post-winding device that winds up the rear roll shade.

  Since the vehicle sunshade device according to the present invention has a structure in which the outer peripheral portion of a translucent member such as glass is supported by a roof panel having a frame-like opening, no horizontal beam is installed below the translucent member. A large-aperture-type light-transmitting area can be formed, and the landscape and sunlight are not blocked by the cross beam when the shade is fully opened. For this reason, a feeling of opening especially at the time of full opening as a sunroof is not spoiled.

  Also, since the front shade and the rear shade have different light shielding rates, for example, the shade with the higher light shielding rate covers most of the light, or the shade with the lower light shielding rate is covered. It is possible to freely adjust the degree of light entering the vehicle, such as moderately blocking light and reducing sunlight. Furthermore, since the amount of each of the front shade and the rear shade can be changed separately, it is possible to finely adjust the light according to each user's request.

  Moreover, in the present invention, each of the shades on the front side and the rear side is a roll shade, and each roll shade is wound and accommodated, so that the space required for housing the shade can be made efficient. For this reason, space saving is achieved under the translucent member, and it is easy to secure the ceiling height (indoor height) in the vehicle interior.

  In such a vehicle sunshade device, the light shielding rate of the rear roll shade is preferably higher than the light shielding rate of the front roll shade. For example, when a child sitting in the back seat of a general passenger car is sleeping, the sun can be blocked by the rear roll shade so that the user can sleep easily. In addition, it is easy to provide a comfortable environment especially for the driver because it is possible to reduce glare and heat while maintaining a feeling of opening and brightness by moderately sunshine to the front seat by the front roll shade This is preferable.

  Furthermore, the vehicle sunshade device of the present invention guides the front slide bar attached to the drawer end of the front roll shade, the rear slide bar attached to the drawer end of the rear roll shade, the front slide bar, and the rear slide bar. And a guide. When the front slide bar and the rear slide bar are guided by the guide, each roll shade is pulled out by an amount corresponding to the amount of movement of the slide bar, or is taken up by a winding device.

  It is also preferable that a magnet for bringing the front slide bar and the rear slide bar into close contact is provided on at least one of the front slide bar and the rear slide bar. When the front and rear roll shades are pulled out to cover the entire surface of the translucent member, both slide bars are automatically adsorbed and brought into close contact.

  Furthermore, it is preferable that a motor for sliding the front slide bar and the rear slide bar is provided. For example, when the translucent member is formed long in the front and back and the front and rear roll shades are arranged apart from each other, if the user can move both the front and rear roll shades electrically, the operation is easy and easy to use. Will improve.

  In this case, the guide is more preferably composed of a dual-purpose guide rail that guides both the front roll shade and the rear roll shade. In such a case, the number of members required for the guide can be reduced, and the installation space required for the guide can be reduced to save space. Such guide rails are, for example, arranged in parallel one by one on the left and right of the translucent area.

  According to the vehicle sunshade device of the present invention, the feeling of opening is not impaired, the light can be easily adjusted, and the indoor height can be easily secured.

  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 10 show an embodiment of a vehicle sunshade device according to the present invention. A vehicle sunshade device 1 according to the present invention is a roof with a light control function (light control roof) provided in a roof portion of a vehicle or the like, for example, and an outer peripheral portion of a translucent member 4 such as glass is formed into a frame-shaped opening. The structure is supported by a roof panel 9 having 9a. For this reason, according to the vehicle sunshade device 1 according to the present invention, it is possible to configure a large-aperture-type translucent area in which no transverse beam is installed below the translucent member 4. Below, the case where such a vehicle sunshade apparatus 1 is applied to what is called a sunroof in a passenger car etc. is demonstrated. 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 the vehicle to form a translucent area. The front roll shade 5 that can be provided, the rear roll shade 8 that has a light shielding rate different from that of 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 roll shade 5 are wound up. A front roller 2 and a rear roller 3 for winding the rear roll shade 8 are provided.

  The glass roof 4 is fixed to the opening 9a of the roof panel 9 of the vehicle of the present embodiment, and a non-openable sunroof is formed (see FIG. 2 and the like). Further, although not particularly illustrated, a portion (roof headlining) other than the glass roof 4 in the vehicle interior ceiling of the vehicle is a molded ceiling in which a knit or the like is used for the skin, for example. 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 covering the inner surface of the glass roof 4 (the surface on the vehicle interior side). In the present embodiment, a front roll shade 5 provided so as to be able to be pulled out from the vicinity of the front portion of the glass roof 4 and a rear roll shade 8 provided so as to be capable of being drawn out from the vicinity of the rear portion of the glass roof 4. A set of shades is arranged (see FIG. 3 etc.). 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.

  A front slide bar 6 and a rear slide bar 7 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. These slide bars 6 and 7 move in the front-rear direction along the guide rail 10 and pull out the roll shades 5 and 8 evenly or send them to the rollers 2 and 3 side to rewind them evenly (see 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 this embodiment, the front roller 2 is provided between the glass roof 4 and the front roof head 9f slightly ahead of the opening (light-shielding 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 the present embodiment, each of the left and right guide rails 10 has a cross-sectional channel shape, for example, and accurately guides 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. It is formed to be able to.

  The geared cable 11 is connected to the front slide bar 6 and the rear slide bar 7 and is provided as a member (transmission cable) for transmitting the driving force of the motors 12 and 13 to the front slide bar 6 and the rear slide bar 7. It is what. The geared cable 11 of the present embodiment has a total of two configurations arranged at both ends of the front slide bar 6 (or rear slide bar 7), and both ends of the front slide bar 6 (rear slide bar 7) are simultaneously connected. They are arranged to move forward or backward by the same amount (see FIG. 1). The pair of left and right geared cables 11 connected to the front slide bar 6 are connected to the pinion 12a of the front motor 12 disposed in front of the glass roof 4, and the pair of left and right geared cables 11 connected to the rear slide bar 7 are connected to the glass roof 4. Are connected to the pinion 13a of the rear motor 13, respectively. Further, at least a portion of the geared cable 11 that meshes with the pinions 12a and 13a of the motors 12 and 13 is provided with teeth and has a rack shape. Further, cable guides 14 for guiding the geared cable 11 are provided on the left and right sides of the front motor 12 and the left and right sides of the rear motor 13 (see FIG. 1).

  The front motor 12 and the rear motor 13 generate driving force for moving the front slide bar 6 and the rear slide bar 7 in the front-rear direction, respectively, and are arranged in front and rear of the glass roof 4 as described above. (See FIG. 1). For example, when the pinion 12a of the front motor 12 is rotated in one direction (counterclockwise direction in FIG. 1), the left and right geared cables 11 are fed backward, and the front slide bar 6 slides backward (FIG. 1 and the like). reference). By this operation, the front roll shade 5 can be sent out by a desired amount to cover the glass roof 4. Moreover, the front slide bar 6 can be stopped at a desired position by stopping the front motor 12. Note that, as described above, the front roll shade 5 is always pulled in the winding direction by the front roller 2, and is thus in a tensioned state during both operation and stop.

  Although not specifically shown, the vehicle of this embodiment is provided with a switch for driving the front motor 12 and the rear motor 13. In this case, the switch is preferably one that drives the front motor 12 and the rear motor 13 independently, and can switch between forward rotation and reverse rotation. For example, in this embodiment, two seesaw switches divided for the front motor 12 and the rear motor 13 are arranged. In such a case, it is possible to operate the front roll shade 5 and the rear roll shade 8 independently, and for the user by matching the direction in which each seesaw switch is tilted with the direction in which the roll shades 5 and 8 move. An input device that is easy to use sensuously can be configured. 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. In addition, if the rear roll shade 8 is pulled out to cover the entire glass roof 4, light can be prevented from being inserted through 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 according to the present embodiment has a structure in which the roll shades 5 and 8 are pulled out or fed in substantially the same plane (or curved surface) without overlapping each other, and the front roof head 9f or the rear roof is provided. The space between the head 9r and the glass roof 4 can be reduced.

  Further, in the present embodiment, magnets 15 and 16 as locking devices for engaging and disengaging both roll shades 5 and 8 are provided on the mutually facing surfaces of the front slide bar 6 and the rear slide bar 7 (see FIG. 1). These magnets 15 and 16 attract each other and stick together when the front roll shade 5 and the rear roll shade 8 cover the entire surface of the glass roof 4 so that there is no gap between the slide bars 6 and 7. . As described above, the vehicle sunshade device 1 of the present embodiment is said to be closed when both the slide bars 6 and 7 are automatically attached when the entire surface of the glass roof 4 is covered with the two roll shades 5 and 8. In that respect, the so-called preparation is complete. The magnetic force between the front magnet 15 and the rear magnet 16 is not too strong, and does not hinder the movement of the slide bars 6 and 7 apart. Incidentally, as described above, not only the magnets 15 and 16 are disposed to face each other, but one of them may be a metal plate, for example, and the arrangement and number illustrated in FIG. 1 may be different. In short, the specific structure is not limited as long as both the slide bars 6 and 7 are automatically joined when the glass roof 4 is covered with the two roll shades 5 and 8 to eliminate the gap.

  According to the vehicle sunshade device 1 of the present embodiment described so far, the user can adjust the light by pulling the front roll shade 5 and the rear roll shade 8 to desired 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 covered by the front roll shade 5, an area not covered by the shade, and an area covered 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 cover the glass roof 4 (see FIG. 8). When the glass roll 4 is covered with the front roll shade 5 and the rear roll shade 8, the magnets 15 and 16 are attracted to join the front slide bar 6 and the rear slide bar 7 as described above. (See FIG. 8). 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 short, the front roll shade 5 and the rear roll shade 8 of the present embodiment can be freely adjusted from the fully open state to the fully closed state, and only one or both of them can be used. In addition, if the pull-out amounts of the roll shades 5 and 8 are appropriately adjusted, the light shielding ratio can be continuously changed from 0% to 100%.

  Further, the vehicle sunshade device 1 of the present embodiment is provided as a so-called large opening type sunroof, and the opening (translucent area) 9a has a drawing amount of the front roll shade 5 and the rear roll shade 8. There are no obstructing cross beams (roof panel reinforcement). For this reason, the whole surface of the glass roof 4 can be covered with the front roll shade 5, and the whole surface can also be covered with the rear roll shade 8 (see FIGS. 6 and 10). Furthermore, since the joining position (attachment position) of the front slide bar 6 of the front roll shade 5 and the rear slide bar 7 of the rear roll shade 8 is also free, the ratio of the 30% light shielding area and the 100% light shielding area is finely adjusted. And can be dimmed. Moreover, since it is a large opening type, it is easy to obtain a large open feeling due to a large panorama when fully opened.

  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 also 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 this embodiment, the case where the light shielding rate of the front roll shade 5 is 30% and the light shielding rate of the rear roll shade 8 is 100% is illustrated, but of course this is only an example, and these can be appropriately changed. It is. Furthermore, it is possible to adopt a configuration in which a roll shade made of a material whose light-shielding rate changes in a gradation shape is adopted so that the light-shielding state changes according to the drawing amount.

  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. Is possible.

  Furthermore, in the above-described embodiment, the case where the present invention is applied to a sunroof of a passenger car is illustrated, but this is only an example. In addition, for example, the present invention is applied to vehicles such as trains, and also to various transportation facilities such as ships and airplanes. It is not hindered. Further, in this case, the light control device having the above-described configuration is obtained by using a light-transmitting member that forms a light-transmitting area, a panel having a frame-shaped opening that supports the outer periphery of the light-transmitting member, and one end of the opening. The first roll shade provided so as to be able to be pulled out from the first end to the other end side, and the first roll shade has a different light shielding rate and is provided so as to be able to be drawn out from the vicinity of the other end of the opening toward the one end side. A second roll shade, a first winding device that winds up the first roll shade, and a second winding device that winds up the second roll shade are provided in the light-transmitting area of the riding vehicle. For example, the light control device can be used as a roll screen of a window.

  Although the case where both the front and rear shades of the vehicle are roll shades has been described so far, this is only an example of a preferred embodiment of the present invention. It is only a suitable example to be an electric type driven by 13. That is, at least one of a plurality of (for example, two) shades that can slide in the closing direction that blocks the glass roof 4 and the opening direction opposite to this can be a shade made of a plate-like member called a hardboard type. At least one of these shades can be manually operated. In the following, the vehicle sunshade device 1 in which the front shade (first shade) is the manual front roll shade 5 and the rear shade (second shade) is the electric plate-like shade 18 will be exemplified. This will be described (see FIG. 11).

  The front roll shade 5 is a shade made of, for example, a cloth or a canvas provided so as to be wound by the front roller 2 as in the above-described embodiment. However, the front roll shade 5 shown in FIG. 11 is a manual type, and the front motor (12), the geared cable (11), the cable guide (14) and the like as described above are not provided. The front roll shade 5 shown in the present embodiment is slidable along the guide rail 10 and can be manually pulled out from the front roller 2.

  The plate-like shade 18 is a so-called hard board type shade, and can slide along the guide rail 10 like the front roll shade 5, that is, slide on the same surface as the front roll shade 5 (the front slide bar 6). The end portions (in this embodiment, the front slide bar 6 and the rear slide bar 7) are provided so as to abut each other (see FIG. 11). Although the plate-like shade 18 of the present embodiment is formed of a material that does not transmit light (transmittance 0), a part or all of the plate-like shade 18 may be formed of a translucent material. Further, although not particularly shown in FIG. 11, the plate-like shade 18 is electrically driven and can be electrically slid by a rear motor, a geared cable, a cable guide or the like (not shown).

  Further, the vehicle sunshade device 1 is provided with a locking device 20 including a locking member 21 and a locked member 22 that maintain one or both of the shades 5 and 18 blocking the glass roof 4. . Although not particularly shown in FIG. 11, the lock device 20 further includes a lock mechanism that maintains the shades 5 and 18 in a locked state and at least one of the shades 5 and 18 in the locked state in a closing direction. An unlock mechanism that releases the lock by sliding is provided. Such a locking mechanism and an unlocking mechanism may be of a known configuration such as used in, for example, a roll blind curtain. For example, a fixed pin is formed on the rotating plate so as to be caught by this pin. At least one of the hooks, the coil spring for biasing the rotating plate, the stopper for positioning the rotating plate so as to maintain the standby state in which the hook can be locked to the pin, and the shades 5 and 18 in the locked state are closed. In the case of further sliding, the tilt plate can be configured to retract the rotating plate and remove the hook from the pin.

  11 shows the case where the locking member 21 is attached to the rear slide bar 7 of the plate-shaped shade 18 and the locked member 22 is attached to the front slide bar 6 of the front roll shade 5, respectively. Since the locking mechanism and the unlocking mechanism can be operated by the relative movement of the locking member 21 and the locked member 22, the arrangement may be reversed. Further, as described herein, the locking mechanism and the unlocking mechanism can be operated by the relative movement of the locking member 21 and the locked member 22, so that the front roll shade 5 and the plate-shaped shade 18 in the locked state are operated. Regardless of which one is slid in the closing direction or both are slid in the closing direction, the unlocking mechanism can be operated to switch the lock device to the unlocked state.

  In such a vehicle sunshade device 1, it is easy to ensure a feeling of opening, and it is easy to ensure a ceiling height (indoor height) in the vehicle. In addition, since the front shade (front roll shade 5) and the rear shade (plate-like shade 18) can be engaged and disengaged by the locking device 20, the electric shade (for example, the plate-like shade 18) is locked in the locked state. By sliding, the manual shade (the front roll shade 5) can be moved together. Further, since the locking device 20 includes an unlocking mechanism that releases the locked state by further sliding the locked plate-like shade 18 in the closing direction, the operation of the electric plate-like shade 18 in the locked state is operated. It is possible to switch between the locked state and the unlocked state only by this. Therefore, for example, the electric plate-like shade 18 disposed on the rear side of the vehicle can be operated from the driver's seat to switch between the locked state and the unlocked state. Further, in the locked state, since the other shade can be operated with the other shade, the vehicular sunshade device 1 operates both shades with a single drive source (motor). There is an advantage that it is possible.

  Here, as another embodiment, the case where the front shade is the roll shade 5 and the rear shade is the plate-like shade 18 has been described. However, the present invention is not limited to this. For example, conversely, the front shade is plate-like. It is possible to combine the shade and the rear shade as a roll shade. Furthermore, the present invention can also be applied to a case where both the front side and the rear side are plate-shaped shades, for example, the front-side plate-shaped shade is a manual type and the rear side plate-shaped shade is an electric type. .
