Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for opening and closing a window glass of an automobile.

[Conventional technology]

Most conventional devices for opening and closing the window glass of automobile doors simply raise and lower the window glass along guide rails that are generally oriented in the vertical direction.
For example, see Japanese Patent Application Laid-Open No. 57-33685).

[Problem that the invention seeks to solve]

In order to reduce air resistance when the car is running and to improve its appearance, the window glass of the car door should be flush with the waist part of the outside of the door and the outside of the car body when closed. It is preferable to have a flush surface so that there is no difference in level between the door and the waist part of the outer surface of the door.

However, on the outer panel side of the car door, there is an outside handle device for opening the door from outside the car.
Since a key cylinder device or reinforcing member for locking and unlocking the door is provided, the conventional window glass opening/closing device that simply moves the window glass up and down along a vertical guide rail does not work. It is not possible to make the upward and downward trajectory of the window glass very close to the outer panel side of the door. Therefore, when the window glass is fully opened, the window glass is located on the inside of the vehicle from the outside surface of the door, etc., and there is a gap between the window glass and the door waist part etc. There is a problem that a difference in level inevitably occurs.

For this reason, Japanese Patent Laid-Open No. 56-81785 has proposed a window regulator for a sashless door that can control the posture of the window glass also in the thickness direction of the door when opening and closing. That is, the window regulator disclosed in the publication has a pair of curved guide rails that guide the lower end of the window glass, and a pair of curved guide rails that guide the lower portions of the window glass on both sides in the longitudinal direction of the vehicle body. These guide rails gradually control the posture of the window glass during lifting and lowering operations, thereby achieving both a flush surface for the satsure-less door and retractability of the window glass.

However, since this window regulator has a structure in which four independent guide rails are individually fixed to the door inner panel, assembly and adjustment of the automobile door is extremely troublesome, which poses a practical problem. Furthermore, since the attitude of the window glass of the window regulator is controlled by drawing a motion trajectory as shown in Figure 5 of the above-mentioned publication, there is no particular problem when the window glass is closed or fully open. When the window glass is left in a half-open state, the upper end of the window glass protrudes outward beyond the outside line of the vehicle body. As a result, when the window glass is in a half-open state, there are problems such as generation of wind noise due to the protrusion of the two ends of the window glass and pedestrians getting caught in the protruding upper end.

An object of the present invention is to provide an automobile window glass opening/closing device that solves these problems.

[Means for solving problems]

The automobile window glass opening/closing device of the present invention includes: a guide rail that is provided on a door or a car body of a car and faces substantially in the vertical direction; a carrier that is slidably mounted on the guide rail; and a door or a car body of the car. a lifting device that is provided on the carrier and that raises and lowers the carrier along a guide rail; a window glass mounting plate that is provided on the carrier so as to be movable laterally and supports a window glass; an upper advancing/retracting means for moving the upper part of the window glass mounting plate laterally relative to the carrier; The present invention is characterized by comprising a lateral moving device having a lower advancing/retreating means for moving the carrier laterally toward the side with a displacement amount larger than the displacement amount of the advancing/retracting means.

[For production]

41 According to the device of the present invention, from the state where the window glass is in the fully open position, the elevating device is operated to lower the window glass slightly, and then the lateral movement device is activated and the window glass is opened together with the window glass mounting plate. By moving the glass sideways toward the inside of the vehicle, and then operating the lifting device again to lower the window glass to the fully open position, the outside handle device installed on the outer panel of the door or the key cylinder device can be removed. , or the window glass can be opened while avoiding reinforcement members.

In addition, by the operation opposite to the above-mentioned operation, that is, from the state where the window glass is in the fully open position, the lifting device is activated to raise the window glass, and then just before the window glass reaches the fully closed position,
Activate the lateral movement device and move the window glass mounting plate.
By moving the window glass laterally toward the outside of the vehicle and then operating the lifting device again to raise the window glass to the fully open position, the window glass can be closed while avoiding the above-mentioned outside handle device. At the same time, when the window glass is closed to the fully closed position, the window glass should be as close as possible to the outside surface of the door, etc., so that there is no step between the outside surface of the window glass and the outside surface of the door, etc. It can be positioned so that it is almost on the same plane as the above.

Further, according to the device of the present invention, when the lateral moving device is operated as described above to move the window glass laterally toward the inside of the vehicle or the outside of the vehicle, the lower part of the lateral moving device moves back and forth. Since the amount of movement of the lower part of the window glass mounting plate by the means is larger than the amount of movement of the upper part of the window glass mounting plate by the upper movement means, the lower end of the window glass is moved around the vicinity of its upper end as a fulcrum. It is possible to give a rotation to the side.

As a result, the amount of lateral displacement of the upper end of the window glass can be made as small as possible.

This means that when the window glass is partially opened, the top edge of the window glass may protrude outside the vehicle, trapping pedestrians, or the top edge of the window glass may protrude into the passenger compartment, narrowing the interior space. This is useful for preventing the upper end of the window glass from coming into contact with the human body of the person getting on and off the vehicle.

(12a) is a large working hole formed continuously at the upper end of the elongated hole (12).Using this working hole (12a),
A central guide member (15), which will be described later, can be fitted into the elongated hole (12).

At the top of the guide rail (10) and behind the elongated hole (12), a recessed groove (13) that is parallel to the elongated hole (12) and recessed toward the inner panel (3) is formed. and
In addition, a rectangular engagement hole (14
) (see Figure 6) are drilled.

The long hole (12) has a reduced diameter part (15a) whose diameter is approximately the same as or slightly smaller than the width in the front-rear direction, and this reduced diameter part (], 5a.

As clearly shown in FIG. 9, the guide member (15) has an internal thread in the center with an enlarged diameter flange (16a) at the end closer to the inner panel (3) and a female thread carved on the inner surface. A tube (16) extends through the bush (17) so as to be relatively rotatable.

A plate-shaped arm (18) facing in the radial direction is fitted around the female threaded pipe (16) on the outer side of the bushing (F) so as to be able to freely rotate relative to the female threaded pipe (]6) and the bushing (17). ing.

A snap ring (
19) is fitted, and this snap ring (19)
By sandwiching the bushing (17) and the arm (18) from both sides by the enlarged diameter flange (16a), the female threaded pipe (16) is prevented from being removed from the guide member (15).

A snap ring (20) is fitted around the outer periphery of the outer end of the female threaded pipe (16), and the female threaded pipe (16) is connected between the snap ring (20) and the above-mentioned central snap ring (19). ) A helical-toothed pinion (21) and a pulley (22) are fitted around the female threaded pipe (16) with a key (23) so that they cannot rotate relative to each other.

A male threaded rod (24) is screwed into the female threaded pipe (16), and the outer end of this threaded rod (24) is connected to the window glass mounting plate (hereinafter simply referred to as the mounting plate) (25). It is pivotally mounted to a bearing portion (26) formed on the inner surface of the lower center portion with a substantially horizontal shaft (27) facing in the front-rear direction.

The mounting plate (25) has a plate shape that is substantially parallel to the guide rail (10) and long in the front-rear direction, and the lower part of the window glass (4) is attached to the outer surface of the mounting plate (25) with appropriate bolts.・It is fixed with the nut (28).

At the front and rear edges of the guide rail (10), a pulley-shaped guide member (29) is provided on the front and rear edges of the guide rail (10), which has flanges (29b) at both ends of the reduced diameter part (29a), similar to the above-mentioned guide member (15). ), and its reduced diameter part (29a) is the guide rail (1
0), and both flange portions (29b) (
29b), the front and rear edges of the guide rail (10) are sandwiched from both sides and engaged with each other.

In the center of each guide member (29), the above-mentioned female threaded pipe (1
A female threaded pipe (30) similar to 6) is fitted through a bush (31) so as to be relatively rotatable.

As in the case of the female threaded pipe (16) shown in FIG. 9, a spacer (32) is provided on the outer periphery of each female threaded pipe (30) from the inner end to the outer end in place of the bush (31) and the arm (18). ), a snap ring (33) similar to the snap ring (19), and a spacer (3) in place of the pinion (21).
4), a pulley (35) similar to the pulley (22), and a snap ring (36) similar to the snap ring (20)
are installed in sequence.

In other words, the configuration of the front and rear guide members (29) is different from the configuration of the central guide member (15) in that the arm (18) and pinion (21) are connected by spacers (32) and spacers (34). It is almost the same as the one it replaced.

In addition, the pulley (35) is a key similar to the key (23) (
The threaded pipe (30) is fixed to the internally threaded pipe (30) with a path shown in the figure.

The outer diameters of both the upper front and rear pulleys (35) are larger than the outer diameter of the lower central pulley (22).

A male threaded rod (37) is screwed into each female threaded pipe (30), and the outer end of each threaded rod (37) is connected to the mounting plate (

This tension pulley (42) is connected to the timing belt (
40) to apply the required tension to the timing belt (40), the arm (18) is fitted with a suitable spring (
(path shown) in the clockwise direction in FIG.

Thus, the central guide member (15) slides or rolls along the elongated hole (12), and the front and rear guide members (29) (29) respectively slide or roll along the front and rear edges of the guide rail (10). (in this case, each guide member (
15) (29) may slide or roll), the mounting plate (25) and the window glass (4) attached to it may move up and down along the guide rail (10). I can do it.

Also, by rotating the pinion (21) counterclockwise in FIG. 4, the timing belt (40)
, each pulley (22), (35) and key (2) are connected to each pulley (22), (35)

), the screw rods (24) and (37) that are screwed into the screws extend outward, and the mounting plate (25) and the window glass (4) are moved outward.

At this time, as mentioned above, by making the upper front and rear pulleys larger, the rotational speed of the pulley (22) and the female threaded pipe (16) is higher than the rotational speed of the pulley (35) and the female threaded pipe (30). , the amount of advance of the screw rod (24) is
37) is larger than the amount of advance.

As a result, the lateral displacement of the lower part of the mounting plate (25) becomes larger than the lateral displacement of the upper part, causing the window glass (4) to have its lower end directed outward with the vicinity of its upper end as a fulcrum. It is possible to apply a minute rotation such as rotating the window glass (
4) The amount of lateral displacement of the upper end can be made as small as possible.

In this embodiment, the outer diameter of the pulley (22) and the outer diameter of the pulley (35) are defined as the vertical length of the window glass (4),
The amount of lateral displacement of the upper end of the window glass (4) is set to be O by setting an appropriate value based on the vertical spacing of the threaded rods (24) (37), the thread pitch, etc.

When the pinion (21) is rotated clockwise in FIG. 4, the pulleys (22) (35) and the female threaded pipe (16) (30
) is rotated in the opposite direction to that in the above case, and each threaded rod (24) (37) is advanced into each female threaded pipe (16) (30) by the operation in the opposite direction to that in the above case, and the window glass is inserted. (4)

52) is lowered, the recess (55a) of the engagement lever (55) is engaged with the protrusion (52a), and the roller (57) is rolled along the outer surface of the guide rail (10). At the same time, the mounting plate (25) and the window glass (4) are lowered to the fully open position (Z).

When the upper actuating piece (52) is raised together with the guard cable (48) from the state where the window glass (4) is in the fully open position (Z), the recess (55a) of the engagement lever (55) moves into the projection (52a). When the mounting plate (25) and the window glass (4) are lifted up and the window glass (4) reaches the slightly open position (Y') just before fully opening,
The lower end of the engagement lever (55) engages with the engagement hole (14) together with the roller (57), and its recess (55a) separates from the protrusion (52a).

By engaging the lower end of the engagement lever (55) with the engagement hole (14), the lowering of the window glass (4) is prevented, and even if the upper actuating piece (52) rises thereafter, the window glass (4) ) is maintained stopped at the slightly open position (Y').

(55b) is connected to the lower end of the engagement lever (55),
This is a stopper to prevent the lower end of the engagement lever (55) and the roller (57) from entering too deeply into the engagement hole (14).

Furthermore, in this embodiment, the motor (50), reduction gear I (51), pinion (49), guard cable (48), etc. are connected to the lifting device (B) and the lateral moving device (C).
It is a common driving means with.

Next, the overall operation of the apparatus of this embodiment will be explained.

As shown in Figure 5, the window glass (4) is in the fully closed position (X).
When the roller (64) is stopped in the recessed groove (13
), and the sliding body (62) is inserted into the compression coil spring (6
3) is pushed inward, and a part of the first sliding rod (62b) of the sliding body (62) is pushed by the upper and lower projections (53a) (53b) of the lower actuating piece (53). The entire load of the window glass (4), mounting plate (25), etc. is supported by the lower protrusion (53b).

In addition, the threaded rod (24) (37) is the female threaded pipe (16).
(30) are in the most extended state, and the window glass (4) is close to the outer panel (2).

Furthermore, the roller (5) at the lower end of the engagement lever (55)
7) is the engagement hole (14) due to the biasing force of the spring (59).
It is in pressure contact with the outer surface of the guide rail (10) slightly above.

From this state, when the motor (50) is operated so that the pinion (49) rotates clockwise in FIG. 1, the guard cable (48) is together with the lower actuating piece (5
3) descends, and its upper protrusion (53a) causes the sliding body (
62), pull down the first sliding rod (62b) and remove the window glass (
4) Lower.

Thereafter, the roller (64) rides on the outer surface of the guide rail (10) from the recessed groove (13), and the sliding body (62) is pushed outward against the biasing force of the compression coil spring (63). , almost at the same time that the notch (66) is positioned directly below the protrusion (53a), the lower end of the engagement lever (55) moves into the engagement hole (1) together with the roller (57), as shown in FIG.
4), the lowering of the window glass (4) is prevented, and the window glass (4) stops at a slightly open position (Y) where its peripheral edge is separated from the seal member (9) on the vehicle body side.

When the window glass (4) has stopped descending and its peripheral edge is separated from the sealing member (9), the guide tube (44)
) in the upright part (44a) of the guard cable (
48) continues to descend further, the protrusion (53a) passes through the notch (66), and the lower actuating piece (53)
is lowered together with the guard cable (48), and the engagement between the guard cable (48) and the pinion (21) causes the pinion (21) to rotate clockwise in FIG. 4.

Note that when the window glass (4) is moving up and down together with the guard cable (48), the pinion (21) remains engaged with the guard cable (48) and moves up and down as one, so the pinion (21) does not rotate and the window glass (
4) and the guard cable (48), the pinion (21) rotates only when a differential occurs between the pinion (21) and the guard cable (48).

When the pinion (21) is rotated clockwise in FIG. 4, each female threaded pipe (16) (
30) are rotated in the same direction, and each screw rod (24) (3
7) enters the guide member (15) (29).

At this time, the displacement amount of the lower screw rod (24) is larger than the displacement amount of the upper screw rod (37), so that the window glass (4) uses its upper end as a fulcrum, and the lower end of the window glass (4) ) to move laterally as if being pulled toward the side.

Guide members (1, 5) (2) of screw rods (24) (37)
9) When the amount of entry into the window is almost at its maximum, the window glass (4)
reaches the slightly open position (Y'), and at this time, as shown in Fig. 7, the two-part actuating piece (52) along with the guard cable (48) descends onto the engagement lever (55). Then, as described above, the tip (52b) kicks out the lower end of the engagement lever (55) from the engagement hole (14), and at the same time, as shown in FIG. The recess (55a) of (55) engages with the protrusion (52a) of the upper actuating piece (52), and the roller (57) immediately moves to the outer surface of the guide rail (10) directly below the engagement hole (14). After that, the window glass (4) remains in that state while the roller (57) rolls along the outer surface of the guide rail (10), and the window glass (4) descends together with the guard cable (48).

When the window glass (4) reaches the fully open position (Z), this is sensed by a suitable sensor (not shown), and based on this, the operation of the motor (50) is stopped.

Then, the guard cable (48) stops moving, and the window glass (4) stops at the fully open position (Z).

Move the window glass (4) from the fully open position (Z) to the fully open position (X)
1, the motor (50) should be operated so that the pinion (49) rotates counterclockwise in FIG.

Then, the window glass (4) is closed by the operation opposite to that described above.

That is, with the four parts (55a) of the engagement lever (55) engaged with the protrusion (52a) of the upper actuation piece (52),
The window glass (4) is lifted by the guard cable (48), and the lower end of the window glass (4) is in a position away from the outside handle (a) and the key cylinder (b), and at the periphery of the window glass (4). When the engagement lever (55) reaches the slightly open position (Y') before contacting the sealing member (9) on the vehicle body side, the lower end of the engagement lever (55) and the roller (57) close together in the engagement hole, as shown in FIG. (14), the recess (55a) is disengaged from the protrusion (52a), and the rising of the window glass (14) is temporarily stopped.

As the guard cable (48) rises thereafter, the pinion (21) and the female threaded pipe (16) (30) are rotated counterclockwise in FIG.
4) (37) advances outward, and due to the difference in the amount of advancement of the upper and lower screw rods (24) and (37) at that time, the window glass (4) uses its upper end as a fulcrum, and its lower end By swinging outward, the peripheral edge of the window glass (4) smoothly moves laterally without biting into the sealing member (9).

When the window glass (4) comes closest to the outer panel (2) and reaches the slightly open position (Y), as shown in FIG. ) is the first protrusion (53b) of the sliding body (62).
It comes into contact with the bottom surface of the sliding rod (62b), and then the window glass (4)
Raise to the fully open position (X).

On the way, the roller (64) sinks into the recessed groove (13), and due to the biasing force of the compression coil spring (63), the sliding body (
62) is pushed inward, and both protrusions (53a) (53b) of the lower actuating piece (53) engage the first sliding rod (62b).
The part other than the notch (66) is securely gripped from above and below.

When the window glass (14) reaches the fully closed position (X), this is sensed by an appropriate sensor (path shown), and based on this, the operation of the motor (50) is stopped, and the guard cable ( 48) stops moving and returns to its original state.

[Examples of odd forms]

In the above embodiment, the upper and lower pulleys (35) and the lower pulley (22) have different outer diameters, so that the amount of advance and retreat of the upper and lower screw rods (37) and (24) is made different. However, the outer diameters of both pulleys (35) (22) were the same, and the upper and lower threaded rods (37) (24) and the female threaded pipe (
30) By varying the thread pitch of (16), the amount of advance and retreat of the upper and lower threaded rods (37) and (24) may be varied.

Further, the present invention can be applied not only to opening and closing a window glass of a car door, but also to opening and closing a window glass provided on a car body.

〔Effect of the invention〕

As is clear from the above, according to the device of the present invention, it is possible to open and close the window glass while avoiding the outside handle device, key cylinder device, reinforcing member, etc. provided on the door or the outer panel side of the vehicle body. When the window glass is fully closed, the window glass is brought as close as possible to the door or the outside surface of the vehicle body, so that the outside surface of the window glass is almost flush with the outside surface of the door, without any difference in level between it and the outside surface of the door, etc. This has the advantage that it can improve the aerodynamic performance when the vehicle is running, and also improve the appearance.

=32- Furthermore, in the present invention, the amount of forward and backward movement of the lower part of the window glass mounting plate by the lower movement means in the lateral moving device is made larger than the amount of movement of the upper part of the window glass mounting plate by the upper movement means. This allows the window glass to be rotated so that its lower end rotates laterally around the vicinity of its upper end as a fulcrum, and the amount of lateral displacement of the upper end of the window glass can be made as small as possible. .

As a result, even if the window glass is moved laterally toward the inner panel below the slightly open position, which is slightly lower than the fully closed position, the top edge of the window glass hardly ever enters the inside of the vehicle. , when the entire window glass is moved in parallel toward the inside of the car, the top edge of the window glass enters the passenger compartment.
It is possible to prevent the interior space of the vehicle from being narrowed or the possibility that the upper end of the window glass will come into contact with the human body of the person getting on and off the vehicle.

Furthermore, there is no need to increase the horizontal width of the sealing member that engages with the upper end of the windowpane to match the amount of lateral movement of the windowpane, so it is almost the same as a conventional sealing member in which the windowpane does not move laterally. Another advantage is that it is possible to use other sealing members.
