The present invention relates to a window opening and closing operation device.

[0002]

2. Description of the Related Art Conventionally, as a window opening / closing device, Japanese Patent Application Laid-Open No. 61-126282 discloses a window opening / closing device.
No. 113370 Tall window opening / closing operation device, Japanese Utility Model 4-11
No. 3773, opening device for smoke exhaust window, actual opening 577-1356
A window opening / closing device of No. 78 and a rope winding device of JP-A-63-44093 are known.

[0003] Japanese Patent Application Laid-Open No. Sho 61-126282 is designed to open and close a shoji by feeding or winding a wire connected to a shoji from a drum. The window is closed by the biasing force of a biasing device interposed therebetween, and the window is closed by winding the wire by rotating the drum with a motor.

[0004] Japanese Patent Application Laid-Open No. Hei 7-113370 discloses that a planetary gear mechanism is interposed between a drive shaft turned by a handle and a drum, and a carrier of the planetary gear is a ratchet wheel.
If the claws are bitten by the ratchet wheel, the handle and the drum are connected dynamically, and by turning the handle, the wire can be wound by the drum to close the window, and conversely, the claws can be moved from the ratchet wheel. If it is removed, the wire is naturally drawn out of the drum by the biasing device between the shoji and the wall, so that the fenestration can be performed.

In Japanese Utility Model Laid-Open Publication No. 4-113673, a drum is rotated forward or backward by a motor so that a window can be opened or closed. When the power is cut off due to fire, etc., the motor is driven by a constantly charged capacitor,
It is open to the public.

In Japanese Utility Model Laid-Open No. 57-135678, the sliding door is opened and closed by a geared cable. The geared cable connected to the shoji side is sent out or pulled in by a gear to open or close the window.

Japanese Unexamined Patent Publication No. 63-44093 discloses a structure in which a wire for opening and closing a shoji is spirally wound around a drum. A spiral groove is formed in the drum, and a nut is screwed into the spiral groove. A pulley for guiding the wire is supported by the nut. When the drum is rotated by the motor to close the window, the nut moves in one direction with the pulley, and the wire is wound around the spiral groove.

SUMMARY OF THE INVENTION Japanese Patent Application Laid-Open No. Sho 61-1262
In the case of No. 82, the power is not transmitted between the drive shaft of the motor and the drum by the roller clutch when the window is opened by the motor. Therefore, when the sliding door is set to the half-open state, the motor must be once fully opened, then the motor is rotated in the window closing direction, and the motor must be stopped during the closing of the sliding door, which requires a troublesome operation. Also, in Japanese Unexamined Patent Application Publication No. 7-113370, it is difficult to stop the sliding door until the sliding door is fully opened once the pawl is removed from the ratchet wheel. It is necessary to rotate the handle in the window closing direction later.

In Japanese Utility Model Laid-Open No. 4-113673, since both opening and closing operations are performed by a motor, it is difficult to quickly open a window faster than driving a motor in an emergency.

[0010] Japanese Utility Model Publication No. 57-135678 detects the stop of the movement of the geared cable, detects the completion of the window closing, and automatically stops the motor.
It does not directly detect the closing force of the shoji and stop it. Therefore, the motor cannot be automatically stopped at the fully opened or fully closed position of the shoji, and the shoji, the window frame, the motor, and the like may be damaged by overload, overcurrent, and the like. It is conceivable to stop the motor automatically by detecting the overcurrent flowing to the motor due to the overload when the sliding door is closed, but the current value rises instantaneously, so the current exceeding the set value will flow unless the detection time is shortened considerably. It is difficult to control the damage prevention. In addition, repeating the number of times even for an instantaneous overcurrent greatly affects the capacity and protection circuit of the power supply device and other connected devices. Further, the closing force of the shoji must be set so as not to be opened by wind pressure or the like and to such an extent that the window is not damaged, but it is difficult to adjust it by the conventional stopping means.

In Japanese Patent Application Laid-Open No. Sho 61-126282, since the closing operation of a shoji is performed by a motor, it is difficult to close a window when an electric circuit is cut off at the time of a power failure, which causes a problem such as crime prevention. . Also, Japanese Patent Application Laid-Open No. 7-113370
Since the door is manually opened and closed by the shoji, there is a problem that the opening and closing operation is troublesome and takes time.

In Japanese Patent Application Laid-Open No. 63-44093, a wire can be wound only one time because a nut is screwed into a spiral groove of a drum. Has the problem that a large drum must be prepared. Therefore, the present invention
Window opening / closing means that can be stopped at any time during the opening / closing operation of a shoji, window opening / closing means that can quickly open a window without being driven by a motor, and the motor is automatically turned on when the shoji is fully opened or fully closed Provided are a window opening / closing means that can be stopped, a window opening / closing means that can easily and quickly close a window, and a window opening / closing means that can neatly wind a wire over a plurality of layers on a drum.

When the fenestration is started at the time of stoppage, the lock of the lock mechanism is unlocked, and the
a is released from the rotation range of the projection 10a of the carrier 10 to allow the rotation of the drum 5 in the window direction a due to the pulling force of the wire H. By engaging with the projection 10a with the rotation of the carrier 10, the rotation of the carrier 10 in the other direction is restricted, and the rotation of the drum 5 in the window closing direction b is allowed. More specifically, the clutch mechanism includes a clutch arm 21 that can be disengaged from the projection 10 a of the carrier 10, a clutch arm 21 and the lock lever 12.
And a sliding stopper 19 interlocked with both.

The clutch arm 21 is a substantially L-shaped member, and is pivotally supported on the substrate 2a via a support shaft 22 at a bent portion thereof.

It is necessary to move to the operable position in a state where Oa restricts the slider 24. A hook holding member 34 is provided between the hook release member 32 and the slider 24 to cause the hook release member 32 to perform such an operation.
The hook holding member 34 is pivotally supported on the substrate 2 a by a pin 34 c so as to be swingable, and a tip portion 34 a that can come and go with the hook holding member 34 and a cam portion 3 that can come and go with the tip of the slider 24.
4b. The hook holding member 34 is connected to the substrate 2a.
The torsion spring 35 interposed therebetween constantly biases the tip portion 34a in a counterclockwise direction such that the tip portion 34a contacts the hook release member 32 and the cam portion 34b faces the tip of the slider 24. By this, release button 2
When the hook 7 is not actuated, the hook releasing member 32 is pushed away by the distal end portion 34a of the hook holding member 34 out of the rotation locus of the projection 40a as shown in FIG. Also, when the release button 27 is operated and the shoji E is opened, FIG.
As described above, the cam portion 34b of the hook holding member 34 slides the slider 24 so that the hook 30a engages with the groove 24d, and at the same time, the cam portion 34b is pushed to the tip of the slider 24, so that the hook holding member 34 34 swings to release the hook release member 32. As a result, the distal end portion 32b of the hook release member 32 enters the rotation locus of the projection 40a.

Even if the projection 40a is stopped at the position where it abuts on the hook releasing member 32 when the slider 24 is to be restrained as shown in FIG. 16, the hook member 30 rotates relatively to the hook releasing member 32. Since it is movable, the hook 30a and the groove 24d always engage.

Automatic Lock Release Mechanism The following automatic lock release mechanism is provided as means for rapidly opening the above-mentioned sash E.

As shown in FIGS. 6 and 7, the automatic unlocking mechanism uses the mechanism of the manual unlocking mechanism extending from the slider 24 to the projection 40a as it is, and the opposite side of the slider 24 from the clutch arm 21. , A small electric motor 36 is disposed. This small electric motor 36 is fixed horizontally on the substrate 2a,
The rotation axis is perpendicular to the sliding direction of the slider 24. A cam 37 is pressed into the tip of the rotating shaft to contact the side surface of the slider 24 and slide the slider 24.

When the small electric motor 36 is driven and the cam 37 makes one rotation in the window closed or half-open state as shown in FIG. 10A. As a result, as shown in FIG. 10A, the lock mechanism releases the restraint of the drum 5 in the window opening direction a, and the clutch arm 21 releases the restraint of the carrier 10. Accordingly, the stay damper K pulls the wire H while extending, and the drum 5 pays out the wire H while rotating in the window opening direction a. And
The stretching force of the stay damper K acts on the shoji E as it is, and the shoji E opens.

Sun Gear Driving Apparatus The sun gear 6 and the drum shaft 3 of the planetary gear mechanism are rotated automatically or manually by the following driving apparatus.

That is, as shown in FIGS. 2B, 3 and 4, the output of the electric motor L is
6 through a roller chain 47 to another sprocket wheel 44, and further to spur gears 40, 39, 7
The light is transmitted to the sun gear 6 and the drum shaft 3 through a gear train composed of The electric motor L can be switched between forward and reverse, and the sun gear 6 rotates forward or reverse according to the switching.

Further, this driving device has the following switching mechanism, and it is possible to switch from electric to manual. As shown in FIGS. 4 and 25, the switching mechanism is provided on the shaft of the sprocket wheel 44 in the torque transmission path between the drum shaft 3 and the electric motor L, And couplings 40a, 41b coaxially and relatively rotatably coupled to each other and the driven side shaft 40d; clutch holes 40b, 41c formed in the couplings 40a, 41b along their center lines; It is slidably inserted into the clutch holes 40b and 41c, and is urged by a spring 42 to stop at a position where the drive side shaft 41 and the driven side shaft 40d are connected. Clutch piece 43 that can move to a non-connection position when pushed
The clutch piece 43 is inserted into the clutch holes 40b and 41c to move the clutch piece 43 to the non-connection position, and the clutch piece 43
And a handle 48 for rotating the driven side shaft 40d via the handle.

The drive side shaft 41 is a shaft to which a sprocket wheel 44 is attached. The driven side shaft 40d is a shaft having the spur gear 40, and is supported on the substrate 2a via a bearing 40c. Joints 40a, 41
b denotes a large-diameter cylindrical portion formed on the drive-side shaft 41 and the driven-side shaft 4
And a small-diameter tube inserted into the large-diameter tube formed at 0d.

The clutch holes 40b and 41c are hexagonal in cross section, and are formed in a range that covers both the large-diameter tubular portion and the small-diameter tubular portion of the joints 40a and 41b. A clutch piece 43 also having a hexagonal cross section is slidably inserted into the clutch holes 40b and 41c. The clutch piece 43 is pushed by a spring 42 inserted into the interior of the clutch holes 40b and 41c, and the drive side shaft 41 and the driven side shaft 40
d is always stopped at a position where it is dynamically connected. When the clutch piece 43 is pressed against the urging force of the spring 42, which is a compression coil spring, and the power transmission between the drive side shaft 41 and the driven side shaft 40d is cut off, the sprocket wheel 44 idles with respect to the drum and the handle. .

The clutch hole is connected to a small-diameter hole 41a in the drive-side shaft 41, and the handle shaft 48a of the handle 48 can be inserted into the small-diameter hole 41a. The handle shaft 48a is a hexagonal bar having a non-circular cross section. The clutch piece 43 has an insertion hole 43a having a non-circular cross section corresponding to the hexagonal bar. Thereby, the clutch piece 43 is pushed down by the handle shaft 48a inserted into the small diameter hole 41a to cut off the transmission, and then the handle 48 is turned by hand, whereby rotation can be transmitted from the spur gear 40 to the sun gear 6.

Window closing detecting device The following window closing detecting device is provided so that the electric motor L can be automatically stopped when the sliding door E is closed by driving the electric motor L.

As shown in FIG. 17, this window closing detection device includes a chain 47 provided in a torque transmission path between the drum shaft 3 and the electric motor L, and the electric motor L b, which is provided on the tight side 47a of the chain 47 when the chain H is driven to detect the further winding of the wire H through the tight side 47a of the chain 47 in a completely closed state.
a. The chain 47 is a roller chain, and the sprocket wheel 4 of the drive side shaft 41
4 and the sprocket wheel 46 on the electric motor L side
It is hung between. Electric motor L closes window b
The intermediate sprocket 58 is engaged with the tension side 47a of the chain 47 when the chain 47 is driven. The intermediate sprocket 58 is rotatably supported at an intermediate position of the tension detecting arm 59. One end of the tension detection arm 59 is swingably supported on the upper surface of the upper plate 2c, and the other end 59a is held between the compression spring 61 and the projection 65. The compression spring 61 is inserted into an insertion hole 60 formed horizontally on the upper surface of the upper plate 2c. The protrusion 65 is formed on the upper surface of the upper plate 2c so as to function as a stopper for the tension detection arm 59. An adjusting screw 62 is screwed into the insertion hole 60, and the amount of compression of the compression spring 61 is adjusted by the advance and retreat of the adjusting screw 62 so that the pressing force of the tension detection arm 59 against the protrusion 65 is adjusted. It has become.

As a result, the tension detecting arm 59 moves the tension side 47 of the roller chain 47 driven in the window closing direction b.
When the tension applied to a becomes large, it is urged counterclockwise through the intermediate sprocket wheel 58 and rotates to the position shown by the two-dot chain line in FIG. The chain 47 of the tension detecting arm 59
Responsiveness to the tension of the compression spring 61 can be adjusted by increasing and decreasing the pressing force of the compression spring 61 due to the advance and retreat of the adjusting screw 62. When the tension on the tension side 47a of the chain 47 increases due to the closing window and reaches a value that opposes the pre-adjusted pressing force of the compression spring 61, the intermediate sprocket wheel 58 of the tension detecting arm 59 is moved to the position above the upper plate 2c. The limit switch, which is the complete window detection sensor 58a, is operated. By the operation of the limit switch, the electric motor L is stopped, and the shoji E is pressed against the window frame B with a tightening force corresponding to the adjustment amount by the adjustment screw 62. In a normal case, the amount of adjustment by the adjusting screw 62 is set so that the shoji E is not opened by wind pressure or the like and the window is not damaged. Further, since the electric motor L is automatically stopped at the fully closed position of the shoji E, damage to the shoji E, the window frame B, and the electric motor L due to overload, overcurrent, etc. does not occur. . Also, repeating the number of instantaneous overcurrents may greatly affect the capacity of the power supply device and the protection circuit, and may also affect other devices. Automatically stops,
There is no such fear.

[0061] When opening the sliding door E with fenestration detection device electric motor L of the drive, so as to automatically stop the electric motor L when the sliding door E is completely opened, it is provided閉窓sensing device, such as: .

As shown in FIGS. 18 and 19, this window-opening detecting device uses a wire H drawn out of the drum 5.
A roller support member 64 that is pressed against the wire H side via the roller 63 and moves by eliminating the tensile force from the wire H;
A complete window detection sensor 63b for detecting when the roller support member 64 has moved.

The roller support member 64 is a lever-shaped frame that is swingably supported by a shaft 64a passed between the substrate 2a and the upper plate 2b of the base 2, and is provided between the substrate 2a and the roller support member 64. FIG. 19 shows the structure of the interposed torsion spring 64b.
It is always biased in the clockwise direction. The roller 63 is rotatably supported by the roller support member 64, and is constantly in contact with the wire H as a result of the roller support member 64 being urged as described above. The roller support member 6
Reference numeral 4 in this urged state contacts the actuator of the limit switch 63b, which is a complete window detection sensor installed on the substrate 2a.

Thus, when a tensile force acts on the wire H, such as when the window is open or closed, the roller support member is opposed to the elasticity of the torsion spring 65 as shown by the solid line in FIG. 64 is pushed back counterclockwise. However, when the shoji E is fully opened, the wire H becomes the shoji E.
As a result, the roller support member 64 loses its pulling force and loosens as a result of being released from the weight of the stay damper K and the urging of the stay damper K. As shown by the two-dot chain line in FIG. Rotate. For this reason,
The limit switch is hit by the protrusion of the roller support member 64, and a signal to the effect that the window has been fully opened is sent from the limit switch to the electrical unit M. With this signal, the electric motor L
Stops automatically. Therefore, the electric motor L is prevented from being damaged due to heat generation due to a long-time operation, and the wire is prevented from being excessively protruded when the electric motor L is fully opened and the wire from being entangled.

As shown in FIG. 3, a rotary damper 57 is attached to the ratchet wheel 11. The rotary damper 57 is mounted on the substrate 2a and has a spur gear 57a at the end of its output shaft. The spur gear 57a meshes with the spur gear 1lb of the ratchet wheel 11. Rotary damper 57
Does not generate a resistance in the direction in which the drum 5 winds the wire H, but generates a resistance in the direction in which the wire H is fed. As a result, the wire H caused by the urging of the fenestration of the shoji E
And the wire H is prevented from being loosened and entangled due to the inertial rotation of the drum 5 after the wire H has been paid out. Further, there is no extra load because there is no resistance from the rotary damper 57 in the winding direction.

Wire winding mechanism The following winding mechanism for the wire H is provided in the vicinity of the window closing detection device in order to smoothly wind or unwind the wire H to and from the drum 5.

As shown in FIGS. 18 and 19, the winding mechanism of the wire H engages with the traverse cam 49 which rotates in conjunction with the rotation of the drum 5 and the cam groove 49a of the traverse cam 49. The follower 53 reciprocates in parallel with the drum shaft 3 and a wire guide 56 attached to the follower 53.

The wire H drawn from the drum 5
A cylindrical column 55 is arranged facing the path of the road. The column 55 is fixed to the upper plate 2b, and the traverse cam 49 is rotatably inserted in the hollow. The lower end of the traverse cam 49 is inserted into the spur gear 50, and the spur gear 50 meshes with the spur gear 11 b integrated with the ratchet wheel 11, so that the traverse cam 49 interlocks with the rotation of the drum 5. become. The outer periphery of the traverse cam 49 has an endless cam groove 4 corresponding to the width of the winding cylinder of the drum 5.
9a is formed, and the support column 55 is formed with an elongated hole 55a corresponding to the width of the winding cylinder. The follower 53 is slidably mounted on the support column 55, and a claw piece 52 that meshes with the cam groove 49a is inserted from a lateral hole 53a formed in a side surface of the follower 53. The claw piece 52 is sealed in the lateral hole 53a by a cap 54 screwed to the side surface of the follower 53. Thus, when the traverse cam 49 rotates in conjunction with the rotation of the drum 5, the follower 53 reciprocates up and down along the column 55.

The wire guide 56 is connected to the wire H
Is a substantially U-shaped guide member surrounding the follower 5
3 is fixed to the side surface. Therefore, when the follower 53 reciprocates as described above, the wire guide 56 reciprocates along the winding cylinder along with the follower 53. Therefore, the wire H is regularly wound up in a layered manner on the drum 5 or is unwound from the drum 5 smoothly.

Next, the operation of the window opening / closing device J will be described for each case. When the electric window is opened, the window is closed before the operation of the switchgear J.
Is in the state shown in FIG.

First, when the window switch N1 (FIG. 2A) of the switch section N exposed on the surface of the cover 1b is pressed, the output shaft L1 of the electric motor L is turned clockwise in FIG. 17B. Starting to rotate, the sprocket wheel 44 rotates clockwise via the chain 47. When the sprocket wheel 44 rotates clockwise, spur gears 49, 39,
7, the drum shaft 3 coaxial with the spur gear 7 rotates clockwise. Since the sun gear 6 of the planetary gear mechanism is fixed to the drum shaft 3 (FIG. 5), the sun gear 6 also rotates clockwise (window direction a) (FIG. 21A). FIG. 21 (a)
In the middle, the internal gear 8a integral with the drum 5 is in a stopped state, so that the planetary gear 9
Rotates counterclockwise and at the same time revolves clockwise around sun gear 6 with carrier 10.

When the carrier 10 is rotated clockwise, as shown in FIG.
Pushes the clutch arm 21 downward, and the clutch arm 2
1 swings counterclockwise against the elasticity of the torsion spring 23 and pushes down the stopper 19. When the carrier 10 further rotates, the projection 10a is
The clutch arm 21 is separated from the position where it comes into contact with 1 and returns to the original position by the restoring elasticity of the torsion spring 23 (FIG. 21C). Further, the lock claw 14 is disengaged from the locking tooth 11a of the ratchet wheel 11. That is, when the clutch arm 21 rotates counterclockwise as shown in FIG. 21B, the extending end 21b comes into contact with the projection 19b of the stopper 19, and the stopper 19 is moved downward against the elasticity of the compression spring 20. To slide. As a result, the extension end 12b of the lock lever 12 is released from the stopper 19, the lock lever 12 rotates clockwise by the restoring elasticity of the torsion spring 18, and the lock claw 14 engages with the locking tooth 1la of the ratchet wheel 11.
Break away from At this time, the return claw 16 is
2 is pushed by the abutment portion 12a and slides to a position where it engages with the locking teeth 1la of the ratchet wheel 11.

When the ratchet wheel 11 is released from the lock pawl 14, the ratchet wheel 1 is pulled by the pulling force of the wire H in the opening direction a.
1 starts rotating in the clockwise direction (window opening direction a), and the wire H is paid out from the drum 5. That is, the ratchet 1
1 is interlocked with the internal gear member 8 and the drum 5 via a spur gear 11b (FIG. 6), and as shown in FIG. 21 (c), the rotation of the ratchet wheel 11 in the clockwise direction is released so that the wire H is released. The internal gear member 8 that rotates integrally with the drum 5 due to the pulling force of, continues to rotate counterclockwise (window opening direction a). Internal gear 8
Rotates counterclockwise, the planetary gear 9 meshing with it rotates about the sun gear 6, and the projection 10 a of the carrier 10 engages with the butting portion 21 a of the clutch arm 21, and the carrier 10 rotates counterclockwise. Rotation is prevented.
On the other hand, the sun gear 6 continues to rotate, the planetary gear 9 rotates in a counterclockwise direction, and the internal gear 8a rotates in a counterclockwise direction (a window direction a). Therefore, the drum 5 integrated with the internal gear 8a is also counterclockwise. The wire H is fed out while rotating in the direction (the fenestration direction a). Thus, the shoji E opens in accordance with the rotation speed of the electric motor L.

When the clutch arm 21 returns to the original position as shown in FIG. 21C, the stopper 19 attempts to return to the original position due to the restoring elasticity of the compression spring 20. It is blocked by the extension end 12b. Thereby, separation of the lock claw 14 from the ratchet wheel 11 is maintained, and rotation of the drum 5 in the fenestration direction a is permitted.

When the sliding door E is completely opened, the pulling force of the wire H is released, and as a result, the full-open detecting member 64 (FIG. 18) rotates to push the limit switch. A signal is sent from the limit switch to the electric unit M, and the electric unit M
To stop. As a result, the opening / closing device J is moved as shown in FIG.
Stop in a state like. In this case, since there is no load from the shoji E side in the fenestration direction a, it is not necessary to hold the lock claws 14. Thus, the automatic stop at the fully open position is completed.

In the case where the electric window is stopped halfway, the switch section N is set during the electric window to make the window half open.
The stop switch N2 (FIG. 2A) may be pressed. Then, the electric motor L stops temporarily, and the sun gear 6 and the like
It stops momentarily as shown in (d). Immediately thereafter, the output shaft L1 (FIG. 17 (a)) is switched from clockwise (opening direction a) to counterclockwise (closed direction b), and the sun gear 6 is rotated counterclockwise (closed direction). b) (FIG. 22)
(E)). Thereby, the planetary gear 9 rotates in the clockwise direction, while the carrier 10 is stopped by the protrusion 10a of the carrier arm 21 abutting against the abutting portion 21a. Thus, the ratchet wheel 11 rotates in the counterclockwise direction (the window closing direction b).

When the ratchet wheel 11 rotates counterclockwise as shown in FIG. 22 (e), the locking teeth 11a of the ratchet wheel 11
6 is pushed back, so that the lock lever 12
Rotates counterclockwise against the elastic force of the torsion spring 18, and the lock claw 14 moves to a position where it can be engaged with the locking tooth 1 la of the ratchet wheel 11. Then, the stopper 19 slides upward due to the restoring elasticity of the compression spring 20, and the extending end 12 b of the lock lever 12 abuts on the contact portion 19 a by the restoring elasticity of the torsion spring 18.

Immediately thereafter, the electric motor L rotates clockwise again. As a result, as shown in FIG.
Rotates in the clockwise direction (window opening direction a), the locking teeth 11a and the lock claws 14 are completely engaged, and the drum 5 does not rotate in the wire H feeding direction, and is completely stopped by the pulling force of the wire H. I do. Meanwhile, the drum 5 stops,
Even if the internal gear member 8 stops, the sun gear 6 continues to rotate clockwise, so that the planetary gear 9 revolves clockwise.
Accordingly, the carrier 10 also rotates clockwise, and the protrusion 1
0a is disengaged from the engagement position of the clutch arm 21 with the abutting portion 21a. When this separation occurs, the electric motor L
To stop. In the state shown in FIG. 22 (f), the rotation of the drum 5 in the counterclockwise direction (the opening direction a) due to the pulling force of the wire H is completely prevented by the engagement between the locking claw 14 and the locking teeth 1la. Therefore, the load on the electric motor L is eliminated. Thereby, the halfway stop of the electric window is completed, and the window maintains the half-open state.

In the case of electrically closing the window, before this operation, the window is in a fully-open or half-open state, and the inside of the opening / closing operation device is in a state shown in FIG.

First, the window closing switch N of the switch section N
₃ Pressing (Fig. 2 (a)), the output shaft L of the electric motor L
₁ (FIG. 17A) starts to rotate counterclockwise (closed window direction b), and the spur gear 7 is rotated via the chain 47 and the gear transmission mechanism.
Rotates counterclockwise (window closing direction b). Since the spur gear 7 and the sun gear 6 are integrated, the sun gear 6 also rotates counterclockwise (closed direction b) as shown in FIG. The internal gear 8a is stopped because it is being pulled by the wire H. Therefore, as shown in FIG. 23 (b), the planetary gear 9 revolves counterclockwise, the projection 10a of the carrier 10 engages with the butting portion 21a of the clutch arm 21, and the rotation is prevented. With the carrier 10 fixed, the sun gear 6
Further rotates, the planetary gear 9 rotates clockwise,
The internal gear member 8 rotates clockwise, and the drum 5 integrated with the internal gear member 8 rotates clockwise (closed window direction b) to wind up the wire H. At this time, the ratchet wheel 11 has the internal gear 8a.
Attempts to rotate in the counterclockwise direction due to meshing with the spur gear 8b on the outer periphery of the lock, and the lock claw 14 allows the rotation of the ratchet wheel (FIG. 23 (c)).

When the sliding door E is completely closed, the sliding door E comes into contact with the window frame B and a large tension is applied to the wire H. Therefore, a large tension is applied to the left side of the roller chain 47 as shown in FIG. Come. Then, the tension detecting arm 59 pivotally supporting the intermediate sprocket wheel 58 rotates counterclockwise against the elasticity of the compression spring 61, and
Move to the position indicated by the two-dot chain line and operate the limit switch. As a result, a signal is sent from the mitt switch to the electrical unit M, and the automatic stop is completed. When the closing of the window is completed, the tightening force of the shoji on the window frame B is determined by the compression spring 61
And the compression force can be adjusted by the screwing amount of the adjusting screw 62.

Thus, the motorized window closing is automatically completed. When stopping the electric window halfway, the stop switch N of the switch section N is the same as in the case of the electric window.
Press ₂ . Then, as FIG. 24 (d), the output shaft L ₁ of the electric motor L switches to rotation in the clockwise direction from the counter-clockwise direction (閉窓direction b) (fenestration direction a), the ratchet wheel 11 is rotated clockwise try to. However, since the clockwise rotation is prevented by the lock claw 14, the internal gear member 8
And the drum 5 does not rotate and maintains the stopped state. Therefore, as shown in FIG. 24 (e), the planetary gear 9 revolves clockwise, the carrier 10 also rotates in the same direction, and its projection 10a
Is disengaged from the engagement position of the clutch arm 21 with the abutting portion 21a. Here, the electric motor L is stopped. Thus, the halfway stop of the electric window closes.

When the window is manually opened, the release button 27 (FIG. 2) protruding from the surface of the cover lb is used.
(A)) is pushed, and the window is rapidly opened by the urging force of the stay damper K toward the window of the shoji B. When the release button 27 is depressed, the inclined cam 25 attached to the lower end thereof as shown in FIGS.
To the right against the elasticity of the compression spring 38. The protrusion 24a on the upper surface of the slider 24 comes into contact with the extension 21c of the clutch arm 21, and the protrusion 24a shown in FIG.
As shown in (a), the clutch arm 21 rotates against the elastic expansion force of the torsion spring 23. When the clutch arm 21 rotates, the stopper 19 slides downward as in the case of the electric fenestration, the lock lever 12 rotates clockwise, and the lock claw 14 engages with the locking teeth 11 a of the ratchet wheel 11. Depart from. As a result, the rotation of the ratchet wheel 11 in the clockwise direction (window opening direction a) is released, the drum 5 becomes freely rotatable in the window opening direction a, and the wire H is pulled by the extension of the stay damper K. , And the window is rapidly opened.

At this time, the clutch arm 21 moves the projection 10 a of the carrier 10 by the restoring force of the torsion spring 23.
However, since the release button 27 is kept depressed downward, the slider 24 remains at the position slid rightward, and the abutting portion 21a of the clutch arm 21 is pressed. Is released from the position where it engages with the projection 10a of the carrier 10, so that the rotation of the drum 5 in the window opening direction is not prevented. Further, even if the release button is manually pulled back to the original position, the hook 30 of the hook member 30 is inserted into the groove 24d on the side surface of the slider 24.
a engages and holds its position against the restoring force of the compression spring 38. That is, before the window is opened, as shown in FIG. 15A, the slider 24 stops at the left end and the hook 30a comes out of the groove 24d, but at the same time when the slider 24 slides to the right, the hook 30a of the hook member 30 is moved. The elastic expansion force of the torsion springs 31 and 33 engages with the groove 24d of the slider 24 to prevent the slider 24 from returning (FIG. 15B). As a result, the separation between the abutting portion 21a of the clutch arm 21 and the protrusion 10a of the carrier 10 is maintained.

In this case, as shown in FIG. 15B, the tip of the slider 24 simultaneously pushes the cam portion 34b of the hook holding member 34, so that the tip 34a comes off the holding position of the hook release member 32. The hook releasing member 32 can come into contact with the projection 40 a of the spur gear 40.

A case in which a window is opened by an external signal A case in which a window is suddenly opened by a fire signal will be described.
In the event of an emergency such as a fire, power is supplied to the switching device J from an external device, so that the small electric motor 36 rotates. When the small electric motor 36 starts rotating, FIG.
As shown in (b), the cam 37 at the end of the output shaft pushes the slider 24 to the right, and the window is rapidly opened in the same manner as in the case of the window opening by the release button. At this time, the limit switch is pushed by the cam 37 to be turned on, but the small electric motor 36 is further rotated, and the limit switch is turned off at the position shown in FIG. Further, as the slider 24 moves rightward, the position of the lock lever 12 changes as shown in FIG.
(A), the limit switch A is turned on by the branch piece of the lock lever 12, and the small electric motor 36 automatically stops by self-interruption.

In the case of electrically closing the window after the window is suddenly opened As described above, after the window is suddenly opened by the open button 27 or the like, as shown in FIG. The clutch arm 2 is disengaged from the engagement position with the teeth 11a.
1 is detached from the projection 10a of the carrier 10,
In the case of electrically closing the windows after the windows are suddenly opened, they must be returned to positions where they can be engaged.

Then, when the electric motor L rotates in the window closing direction b as shown in FIG.
0 rotates counterclockwise, and the protrusion 40a on the upper surface rotates the hook release member 32 clockwise. When the projection 32a of the hook release member 32 abuts on the hook member 30, the hook member 30 rotates integrally with the hook release member 32 in the same direction, separates from the groove of the slider 24, and releases the constraint of the slider. The slider 24 is a compression spring 3
It slides to the left by the elasticity of 8. The clutch arm 21 released from the slider 24 has a torsion spring 23
Of the carrier 10 and engages with the projection 10a of the carrier 10 to prevent its rotation in the counterclockwise direction. In this state, the drum 5 starts rotating in the window closing direction b, and the ratchet wheel 11 rotates counterclockwise, and the locking teeth 11a thereof rotate.
