Description

TECHNICAL FIELD The present invention relates to a window regulator for opening and closing a window glass of an automobile.

[Conventional technology]

Most conventional window regulators for automobile doors are those that simply raise and lower the window glass along a guide rail that is oriented substantially vertically (see, for example, Japanese Patent Laid-Open No. 57-33685).

[Problems to be solved by the invention]

In order to reduce air resistance when the car is running and to improve the appearance, the window glass of the car door should be close to the waist of the door or the outer surface of the car body when it is closed. It is preferable to form a so-called flash surface so that it is located above and there is no step between the outer surface of the door and the waist.

However, on the outer panel side of the automobile door, there is an outside handle device for the total operation of opening the door from outside the vehicle,
Since a key cylinder device for locking and unlocking the door, a reinforcing member, etc. are provided, in the conventional window regulator that simply raises and lowers the window glass along the vertical guide rails, I couldn't move the hoisting trajectory very close to the outer panel side of the door,
Therefore, there is a problem that when the window glass is fully closed, the window glass is located on the inner side of the vehicle than the outer surface of the door and a step is inevitably formed between the window glass and the waist portion of the outer surface.

For this reason, conventionally, JP-A-56-81785 proposes a window regulator for a sashless door that can control the attitude of the window glass even 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 for guiding the lower end portion of the window glass and a pair of curved guide rails for guiding the lower portions of the window glass in the front-rear direction of the vehicle body. It is fixed to the panel, and these guide rails gradually control the attitude of the window glass during the raising / lowering operation, thereby achieving both flash surface of the sashless door and storability of the window glass.

However, in this window regulator, as shown in FIG. 5 of the above-mentioned publication, the window glass draws a locus of movement such that the upper end portion of the window glass goes beyond the outer line of the vehicle body and projects outward. Since there is no special problem in the fully open state and the fully closed state since the attitude is controlled, when the window glass is in the half open state, the upper end of the window glass protrudes outward more than the outer line of the vehicle body, Due to the protruding upper edge of the window glass, wind noise may be generated when the vehicle is running, or the upper edge of the protruding window glass may collide with a pedestrian, a building, or the like. There is a problem.

It is an object of the present invention to provide a window regulator that solves such problems.

[Means for solving problems]

 FIG. 1 is a diagram showing the basic concept of the present invention.

The window regulator of the present invention, as shown in FIG. 1, guides a lower portion (2a) of a carrier plate (2) fixed to a window glass (1), and guides a lower guide rail (3) which is substantially vertically oriented. And a guide rail (4) for guiding the upper part (2b) of the carrier plate (2), which is oriented substantially vertically, in the door (5).
Further, the carrier plate (2) and the window glass (1) are connected to the guide rails (3) and (4) by an elevating device (6) provided in the door (5) (see the embodiment after FIG. 2). In the window regulator (A) which is configured to be moved up and down along the direction, the upper portions of the guide rails (3) and (4) are respectively provided with bulging portions (3a) and (4a) that bulge outwardly. In addition to the curved shape provided, the starting point (4x) of the bulging part (4a) of the upper guide rail (4)
From the starting point (3x) of the bulging portion (3a) of the lower guide rail (3) to the portion (2a) (2a) (guided by the guide rails (3) and (4) of the carrier plate (2). It is characterized by being positioned higher than the vertical spacing (d1) between 2b), that is, the spacing (d2) between both start points (3x) (4x) is greater than the spacing (d1) (d2 ≧ d1). I am trying.

[Action]

According to the window regulator (A) of the present invention configured as described above, the ascending / descending locus (B) of the lower end portion of the window glass (1) near the upper limit position (X) of the window glass (1).
Is displaced toward the outside of the door (5), and the ascending / descending locus (C) of the upper end portion of the window glass (1) is
It can be made to have an arc shape with a curvature close to that of (1) to face the inside of the door (5).

That is, when the carrier plate (2) and the window glass (1) are lifted by the lifting device (6), they are guided by both guide rails (3) and (4), and the upper limit position of the window glass (1) ( X), the lower part (2a) of the carrier plate (2) reaches the starting point (3x) of the bulging part (3a) of the lower guide rail (3), and the bulging part (3a) is passing through. The upper part (2a) of the carrier plate (2) is slightly behind the lower part (2a), and the upper guide rail (4)
When reaching the starting point (4x) of the bulging part (4a) and passing therethrough, the window glass (1) is rotated such that its lower end rotates outward with the vicinity of its upper end as a fulcrum. As shown in FIG. 1, the window glass (1) has a lower end portion which is displaced toward the outside of the door (5) and an upper end portion which has a curvature close to that of the window glass (1). Draw an arc-shaped locus, and move upward toward the inside of the door (5).

As a result, the amount of lateral displacement of the upper end portion of the window glass (1) becomes small, and when the window glass (1) is in the half-opened state, the upper end portion of the window glass (1) is closer to the outside line (L) of the vehicle body. Even when the vehicle is running, wind noise may be generated when the vehicle is running, or the upper end of the protruding window glass may be pedestrians, buildings, etc. It is possible to solve problems such as collision and bad appearance.

Further, according to the present invention, the window glass (1) is replaced by the door (5).
The outside handle device (7) for door opening operation provided on the outer panel (5a) side, the key cylinder device for locking and unlocking (not shown), the reinforcing member (8), etc. In addition, since the lower end of the window glass (1) is pushed outward near the upper limit position (X), the door (5) can be made thinner and the window glass (1) can be made thinner.
It is possible to reduce the level difference between the window glass (1) and the waist portion of the outer surface of the door when fully closed.

When lowering the window glass (1) from the upper limit position (X) by the elevating device (6), the window glass (1) follows the same trajectory as in the above case in reverse.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, the door (5) is composed of an outer panel (5a) on the outer side of the vehicle and an inner panel (5b) on the inner side of the vehicle. On the inner panel (5b) side of the door (5),

As shown in FIGS. 2 to 4, both boards (9) and (10) have upper guide guides having a forward U-shaped cross section from the front (left side in FIG. 2) side of the vehicle toward the rear side. A rail (4), a guide rail (11) for forward / backward movement having an outward U-shaped cross section, a lower guide rail (3) having a forward U-shaped cross section, and an upper guide having a forward U-shaped cross section. The rails (4) (hereinafter, simply referred to as guide rails) are fixed to each other in a slightly rearward and upward inclined state and in parallel with each other with an appropriate interval.

That is, in this embodiment, there is one guide rail (3) for lower guide and one guide rail (4) for upper guide.
Are two of the same shape and size.

The back surface shape of each guide rail (4) (11) (3) (4) is shown in FIGS. 3 and 5.

As can be seen from these figures, the guide rail (3)
(4) (4) has a curved shape with bulging portions (3a) (4a) (4a) that bulge outwardly toward the outside, and the guide rail (11) has a slightly upper portion. It is a straight line that bends inward.

As described above, the relationship between the bulging portion (3a) of the guide rail (3) and the bulging portion (4a) of each guide rail (4) is between the starting points (3x) (4x) of the guide rails (3). The distance (d2) is equal to both guide rails (3) in the carrier plate (2).
It is larger than the vertical distance (d1) between the portions (2a) and (2b) guided by (4).

As shown in FIGS. 2 to 4 and 6, a guide roller device (12) is provided at the center of the lower portion of the inner surface of the carrier plate (2).

The guide roller device (12) includes a bracket (13) fixed to the carrier plate (2) and having a substantially L-shaped plane, and a shaft (14) facing the front-rear direction at the tip of the bracket (13). A main roller (15) pivotally supported by a shaft and a pivoting lever (17) pivotally mounted on a shaft (14) and always urged clockwise by a spring (16) in the clockwise direction in FIG. And the shaft (14) at the tip of the turning lever (17).
Swing roller (19) pivotally supported by an axis (18) parallel to
It consists of

In the guide roller device (12), the main roller (15) is moved to the outer side piece (3b) of the guide rail (3) and the swing roller (19) is moved to the inner side by the biasing force of the spring (16). By rolling the side pieces (3c) of the carrier plate under constant pressure, the lower portion (2a) of the carrier plate (2) can be smoothly guided along the guide rails (3). There is.

The outer diameters of the main roller (15) and the swing roller (19) are
By making the distance between both side pieces (3b) (3c) of the guide rail (3) slightly smaller, the lower part (2a) of the carrier plate (2) is laterally moved by an external force larger than the biasing force of the spring (16). It is possible to move a little.

As shown in FIGS. 2 to 4 and 7, guide roller devices (20) having the same structure are provided on both upper sides of the inner surface of the carrier plate (2).

Each guide roller device (20) has the same configuration as the guide roller device (12) described above, except that the turning lever (25) is oriented downward.

That is, each guide roller device (20) includes a bracket (21), a shaft (22), a main roller (23), which corresponds to the components (13) to (19) of the guide roller device (12).
Spring (24), downward turning lever (25), shaft (2
6), rocking roller (27), etc.

In each guide roller device (20), the main roller (23) is moved to the outer side piece (4b) of the corresponding guide rail (4) by the biasing force of the spring (24), and the swing roller (27). Also rolls on the inner side pieces (4c) while being constantly in pressure contact with each other, so that both sides of the upper part (2b) of the carrier plate (2) are smoothly guided along the guide rails (4). Is able to.

For the same reason as in the case of the guide roller device (12), the outer diameters of the main roller (23) and the swing roller (27) are determined from the distance between the side pieces (4b) (4c) of each guide rail (4). It is a little small.

As shown in FIG. 2, FIG. 4, FIG. 8 and FIG. 9, a guide is provided between the guide roller device (12) and the front guide roller device (20) on the inner surface of the carrier plate (2). A roller device (28) is provided.

The guide roller device (28) includes a bracket (29) fixed to the carrier plate (2) and having a crank-shaped plane, and a shaft (30) facing the left and right directions at the tip of the bracket (29). Up and down 1 pivoted with
Between the pair of main rollers (31) (31) and both main rollers (31) (31) at the tip of the bracket (29), a shaft (32) oriented in the left-right direction is pivotally attached, and the tips are appropriately attached. Of the rotary lever (34), which is always urged counterclockwise in FIG. 9 by the spring (33) of the rotary lever (34), and the eccentric part of the rotary lever (34) with the shaft (35). The rocking roller (36) is supported.

In the guide roller device (28), the upper and lower main rollers (31) are moved to the rear side piece (11a) of the guide rail (11) and the swing roller (36) is moved to the front by the biasing force of the spring (33). By rolling on the side pieces (11b) of the carrier under constant pressure, the carrier plate (2) is prevented from being displaced in the front-rear direction and is prevented from rotating around the horizontal axis in the left-right direction. It can guide smoothly along the guide rail (11).

In the guide roller device (28), the outer diameters of the main roller (31) and the swing roller (36) are set on both sides of the guide rail (11) in order to reduce the play in the front-back direction of the carrier plate (2). It is very close to the space between the pieces (11a) (11b).

On the carrier plate (2), the center of the lower end of the curved window glass (1) having a large curvature is fixed by bolts and nuts (not shown).

The lifting device (6) is the inner panel (5b) of the door (5).
The case (37) fixed to the side, the winding drum (38) rotatably provided on the case (37), and the case (3
A reversible motor (40) which is provided in 7) and rotates the winding drum (38) forward and backward through a speed reducer (39);
It is composed of an ascending cable (41) and a descending cable (42).

One end of the ascending cable (41) is fixed to the carrier plate (2), and the guide rail (11) extends from there.
After being wound around the winding drum (38), it is guided upward so as to extend parallel to the above, passes through a guide tube (43) fixed to the upper substrate (9), and faces forward and downward. The other end is fixed to the outer circumference of the winding drum (38).

One end of the descending cable (42) is fixed to the carrier plate (2), and the guide rail (11) extends from there.
And the like, and is guided downwardly through a guide tube (44) fixed to the lower substrate (10), and then directed to the winding drum (38), and a rising cable (38). After being wound in the direction opposite to the winding direction of (41), the other end is fixed to the outer circumference of the winding drum (38).

In FIG. 1, reference numeral (45) is a seal member provided at a door opening on the vehicle body side of an automobile, and when the door (5) is closed, the window glass (1) is raised to an upper limit position (X). Then, the upper end of the window glass (1) comes into close contact with the seal member (45) to prevent rainwater or the like from entering the vehicle interior.

In addition, when the back surface shape of the guide rails (3) and (4) is formed as shown in FIG. 5, when the window glass (1) is moved up and down with the door (5) opened, the window glass (1) The upper end of the window follows the ascending / descending locus (C ′) shown by the imaginary line in FIG. 1, but when the window glass (1) is moved up and down with the door (5) closed, the front and back of the window glass (1) The upper end of the edge is in sliding contact with the seal member (45), and the elasticity of the seal member (45) pushes the upper end of the window glass (1) slightly outward.
As a result, the upper end of the window glass (1) follows the ascending / descending locus (C).

The slight tilting of the window glass (1) at this time causes the outer diameters of the main rollers (15) (23) and the like to be different from those of the guide rails (3) (4) in the guide roller devices (12) (20) described above. The main rollers (15) (23) and the like can be slightly swung laterally within the respective guide rails (3) (4) by making the distance smaller than the distance between the both side pieces (3b) (3c) (4b) (4c) in. By doing so, it is allowed.

When the door (5) is opened from the fully closed state of the window glass (1), the spring (1) in each guide roller device (12) (20) is
6) Due to the urging force of (24), the upper edge of the window glass (1)
It is returned to the ascending / descending locus (C ').

Since this embodiment has the above-mentioned configuration, when the winding drum (38) is rotated clockwise by the motor (40) in the winding drum (38), the raising cable (41) is attached to the winding drum (38). ) Is wound and the descending cable (42)
Are unraveled by the same amount, and the carrier plate (2)
And the window glass (1) is raised.

At the time of this ascent, the guide roller device (12) follows the guide rail (3), the guide roller device (20) follows the guide rail (4), and the guide roller device (28) follows the guide rail (11). As they move along the respective directions, the lower end and the upper end of the window glass (1) rise along the ascending and descending loci (B) and (C) as shown in FIG.

That is, from the lower limit position (Y) of the window glass (1) shown by the solid line in FIG. 1 to the intermediate position (Z) where the guide roller device (12) approaches the bulging portion (3a) of the guide rail (3). While rising, the lower half of the guide rail (4) is oriented in a substantially vertical direction, while the lower half of the guide rail (3) is slightly upwardly inclined outward, so that the window glass (1 ), The lower part (2a) of the carrier plate (2) is gradually pushed outward with respect to the upper part (2b), and the window glass (1) is given a slight rotation in the clockwise direction in FIG. As a result, the lower end portion and the upper end portion of the window glass (1) draw up-and-down trajectories (B) and (C) that are substantially the same as the curved surface of the window glass (1) and almost the same as its extension. While the windowpane (1) rises from the intermediate position (Z) to the upper limit position (X), the windowpane (1) operates according to the same principle as that described above as the [action] of the present invention.
The upper end forms an arc shape with a curvature close to that of the window glass (1), faces the inner side of the door, and the lower end moves upward while deviating toward the outer side of the door (5), and finally again. Ascends along the curved surface of the window glass (1) and reaches the upper limit position (X).

As described above, when the door (5) is opened, the upper end of the window glass (1) follows the ascending / descending trajectory (C ′), and when the door (5) is closed, the window glass ( The upper end of 1) rides on the outer surface of the seal member (45) and is displaced outward from the ascending / descending locus (C ′).
Follow the ascending / descending trajectory (C). At this time, the urging forces of the springs (16) and (24) in the guide roller devices (12) and (20) act on the upper end of the window glass (1) so as to return to the ascending and descending locus (C '). By this biasing force, the upper end portion of the window glass (1) is brought into close contact with the seal member (45).

When you want to lower the window glass (1), use the motor (40)
Thus, the winding drum (38) may be rotated counterclockwise in FIG.

Then, the descending cable (42) is wound around the winding drum (38), and the ascending cable (41) is unraveled, and the carrier plate (2) and the window glass (1) are descended.

At this time, the lower end and the upper end of the window glass move up and down along the loci (B) and (C) or (C ') by the action opposite to the above case.
Reverse to descend.

In the above embodiment, in addition to what will be described later as [effect of the invention], each guide rail (3) (4) (4) (1
The upper and lower ends of 1) are fixed to the boards (9) and (10) respectively, and they can be integrally attached and detached in the door (5), which is an advantage that manufacturing work and maintenance and inspection work are easy. There is.

[Modification]

In the above-mentioned embodiment, the lifting device (6) is of the cable drive type, but may be of the X-arm type as disclosed in the above-mentioned Japanese Patent Laid-Open No. 56-81785, or manually. It may be an operation type or the like.

In addition, the lower guide rails (3) may be two and the upper guide rails (4) may be one, or both guide rails (3) and (4) may be one or two or more, respectively. Good.

〔The invention's effect〕

As is apparent from the above, according to the present invention, the lateral displacement amount of the upper end portion of the window glass becomes small, and when the window glass is in the half-opened state, the upper end portion of the window glass is outside the outer line of the vehicle body. As in the past, the protruding upper edge of the window glass causes wind noise when the vehicle is running, or the upper edge of the protruding window glass collides with pedestrians, buildings, etc. Can be eliminated, and the appearance can be improved.

Further, according to the present invention, the window glass is moved up and down while avoiding the outside handle device for door opening operation provided on the outer panel side of the door, the key cylinder device for locking and unlocking, or the reinforcing member, and Near the upper limit position, the lower edge of the window glass is pushed outwards, so the entire door can be made thinner, and between the window glass and the waist of the door outer surface when the window glass is fully closed. There is an advantage that the steps can be reduced as much as possible.
