<Operation of dimming blind mechanism 7 and wind glass falling prevention mechanism>
Here, the operation of the light control blind mechanism 7 and the window glass lowering prevention mechanism will be described with reference to FIGS.

FIG. 4 is a configuration diagram for explaining the operation when the window glass is raised (until the top dead center is restricted), FIG. 5 is a configuration diagram for explaining the operation after the top dead center is restricted, and FIG. 6 is a dimming blind mechanism. FIG. 7 is a block diagram for explaining the operation when the light-controlling blind mechanism is deactivated and the light is transmitted. 8 is a configuration diagram for explaining the operation when the window glass is lowered.
(When lifted (until top dead center restraint))
This will be described with reference to FIG.

The window glass provided on the shoe 3 is in a light transmitting state by the light control blind mechanism 7 provided on the shoe 3.
At locations other than the top dead center, the lock lever 65 is pressed against the first guide G1 of the guide portion G of the guide rail 1 by the biasing force of the lock lever spring 75 (in the direction of arrow R in the figure). Touching.

  When the wind glass rises, that is, when the drum 13 winds up the upper wire (first wire) 21, the contact arm portion 45 b of the first lever 45 connected to the upper wire 21 is provided on the lock arm portion 43 b of the blind lever 43. The large diameter portion 44 b of the bolt 44 is pushed, and the small diameter portion 44 c of the bolt 44 pushes the groove 65 d of the blind lever restraining arm portion 65 b of the lock lever 65. The force F received by the lock lever 65 is in the axial direction of the second bolt 61 that is the rotation shaft of the lock lever 65, and no rotation moment is generated in the lock lever 65.

  As shown in FIG. 4, even when the slider 3 moves to the top dead center and the winding of the upper wire (first wire) 21 of the drum 13 stops, the small diameter portion of the bolt 44 provided on the blind lever 43. The lock lever 65 urged in the R direction by the lock lever spring 75 by the frictional force generated between the peripheral surface of 44c and the peripheral surface of the groove 65d of the blind lever restraining arm portion 65b of the lock lever 65 is Hold position.

Further, the lock lever 65 is in a position where the stopper portion 65e cannot abut (engage) the stopper pin 95 of the guide rail 1, and the window glass lowering prevention mechanism is not operated.
(After top dead center restraint)
This will be described with reference to FIG. Here, the window glass is slightly lowered. That is, the drum 13 winds the lower wire (second wire) 23. Then, the lock lever release arm portion 63b of the second lever 63 connected to the lower wire 23 pushes the guide arm portion 65a of the lock lever 65, and the lock lever 65 rotates slightly. Then, the frictional force generated between the peripheral surface of the small diameter portion 44c of the bolt 44 provided on the blind lever 43 and the peripheral surface of the groove 65d of the blind lever restraining arm portion 65b of the lock lever 65 is reduced, and the lock lever 65 rotates in the R direction by the urging force of the lock lever spring 75, and comes into contact with the first guide G 2 of the guide portion G of the guide rail 1. Furthermore, the rotation of the lock lever 65 releases the engagement between the groove 65d of the blind lever restraining arm portion 65b and the small diameter portion 44c of the bolt 44 provided on the blind lever 43 (the state where the secondary base 33 can be lowered). Become).

Further, even if the locking lever 65 rotates to a position where the stopper portion 65e can contact (engage) with the stopper pin 95 of the guide rail 1, even if a force in the opening direction acts on the window glass, the locking lever 65 The stopper portion 65e comes into contact (engagement) with the stopper pin 95 of the guide rail 1 to actuate a window glass lowering prevention mechanism that prevents the window glass from lowering.
(Light control blind mechanism operation)
This will be described with reference to FIG. Next, the window glass is raised slightly. That is, the drum 13 winds the upper wire (first wire) 21. The contact arm portion 45b of the first lever 45 connected to the upper wire 21 pushes the large diameter portion 44b of the bolt 44 provided on the lock arm portion 43b of the blind lever 43, and the blind lever 43 rotates. By rotation of the blind lever 43, the secondary base 33 connected to the secondary base connecting arm portion 43a is lowered, and the dimming blind mechanism 7 is operated. Therefore, the overlap between the first polarizing plate and the second polarizing plate changes, and changes to a light shielding state.

At this time, when the lower wire 23 is drawn out from the drum 13, the second lever 63 biased by the second spring 77 rotates in the direction of taking the slack of the lower wire 23 (the direction in which the lower wire 23 is stretched).
Further, since the lock lever 65 is not rotating, the stopper portion 65e can abut (engage) with the stopper pin 95 of the guide rail 1, and the operation of the window glass lowering prevention mechanism continues.
(Light control blind mechanism release)
This will be described with reference to FIG.

Lower the wind glass. The drum 13 winds the lower wire (second wire) 23. Then, the second lever 63 connected to the lower wire 23 rotates.
Further, the wire connecting arm portion 63a of the second lever 63 pushes the bolt 44 of the blind lever 43, the blind lever 43 rotates in the direction opposite to the blind ON operation, the secondary base 33 rises, and the dimming blind mechanism 7 Is released. Accordingly, the overlap between the first polarizing plate and the second polarizing plate is changed, and the light transmission state is restored.

At this time, the first lever 45 urged by the first spring 49 by the rotation of the blind lever 43 and the upper wire 21 being fed out from the drum 13 causes the upper wire 21 to sag (the upper wire 21 Rotate in the direction of tension).
Further, since the lock lever 65 is not rotating, the stopper portion 65e can abut (engage) with the stopper pin 95 of the guide rail 1, and the operation of the window glass lowering prevention mechanism continues.
(Descent operation)
This will be described with reference to FIG.

  Continue descending the wind glass. The drum 13 winds the lower wire (second wire) 23. Then, the second lever 63 connected to the lower wire 23 rotates, the lock lever release arm portion 63b pushes the guide arm portion 65a of the lock lever 65, the lock lever 65 rotates, and the roller 73 of the guide arm portion 65a It becomes possible to contact the first guide G1 of the guide portion G of the guide rail 1. Further, due to the rotation of the lock lever 65, the groove 65d of the blind lever restraining arm portion 65b and the small diameter portion 44c of the bolt 44 provided on the blind lever 43 are engaged again, and the secondary base 33 is prohibited from descending.

Further, the lock lever 65 rotates to the x position where the stopper portion 65e cannot contact the stopper pin 95 of the guide rail 1, and the operation of the window glass lowering prevention mechanism stops.
That is, the second lever 63 and the lock lever 65 constitute an engagement release mechanism that releases the engagement between the stopper pin 95 and the stopper portion 65e of the lock lever 65- of the carrier 4.

According to the above configuration, the following effects can be obtained.
(1) By changing the overlap between the first polarizing plate and the second polarizing plate, the first polarizing plate, the window glass composed of the second polarizing plate disposed at a position at least partially overlapping the first polarizing plate, and By having a dimming blind mechanism 7 for switching between transmission and shielding of light, it is possible to switch between transmission and blocking of light by changing the overlap between the first polarizing plate and the second polarizing plate, so that the transmission state is maintained. This requires no electricity and saves energy.

(2) The light control blind mechanism 7 has a lock lever 65, and when the lock lever 65 is moved from the first guide G1 to the second guide G2 when the window glass is fully closed, the first polarizing plate and the second polarizing plate The mechanism is simplified by changing the overlap with the two polarizing plates.
(3) A first lever 45 having an upper wire (first wire) 21 connected to the shoe 3, a first spring 49 for urging the first lever 45 in the direction in which the upper wire 21 is stretched, and a lower wire (second wire) 23 Since the slack between the upper wire 21 and the lower wire 23 can be removed by the second lever 63 connected to the second lever 63 and the second spring 77 that biases the second lever 63 in the direction in which the lower wire 23 is stretched, the configuration is simple. .

 (4) Since the first lever 45 and the second lever 63 are provided offset in the thickness direction of the window glass, even if the carrier 4 is small, the rotation plane of the first lever 45 and the second lever Since the rotation plane of 63 is different, interference between the first lever 45 and the second lever 63 can be prevented.

 (5) In the first lever 45 and the second lever 63, the first wire connecting portion 45d of the first lever 45 and the second wire connecting portion 63c of the second lever 63 are connected to the first bolt (the first lever 45). By forming so as to be positioned between the rotating shaft 41 and the second bolt 61 (the rotating shaft of the second lever 63), the space of the carrier 4 can be saved.

 (6) It has a guide rail 1 provided along the opening and closing direction of the window glass, a shoe 3 movably engaged with the guide rail 1 and provided with the window glass, and a drive mechanism for driving the shoe 3. A stopper pin 95 is provided in a portion other than the shoe 3 and the window glass. When the window glass is not in the fully closed state, the shoe 3 cannot be brought into contact with the stopper pin 95, and moves when the window glass is in the fully closed state. By providing the lock lever 65 that can come into contact with the pin 95, even if a force for moving the window glass in the closed state from the outside acts in the closing direction, it is difficult to move.

  In addition, this invention is not limited to the said embodiment. In the above embodiment, when the window glass is fully closed, the lock lever 65 of the carrier 4 abuts against a stopper pin (stopper) 95 provided on the guide rail 1 to prevent the window glass from dropping in the opening direction. However, it is not limited to the fully closed state. A stopper pin (stopper) 95 may be provided to prevent the window glass from dropping in the opening direction when the window glass is stopped at a predetermined position other than the fully opened state.
