Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to an automobile window regulator in which a window glass is raised and lowered by a wire. This invention relates to a wire-type window regulator that can be raised and lowered from the side.

(Prior Art) Generally, an openable window of an automobile is opened and closed by raising and lowering the window glass. In that case, it would be good if the glass could be raised and lowered while maintaining a horizontal position, but as in the case of quarter windows, for example, the rear end of the glass interferes with the rear wheel house, etc. may not be able to be stored. Therefore, in such a case,
The front end of the glass is raised and lowered more than the rear end, and the glass is stored in a state where the front end is lowered.

A wire type window regulator is normally used to raise and lower a window glass whose front end side is tilted up and down. This wire-type window regulator has a carrier plate attached to the lower end of the glass, and the glass is raised and lowered by driving a wire fixed to the carrier plate in the vertical direction. be.
The glass is guided by a guide plate attached to the vehicle body, and the front end of the glass moves faster than the rear end as the glass moves up and down.

Conventionally, even in the case of a wire type window regulator for a window glass in which the front end side rises and falls more than the rear end side, the carrier plate has been fixed to the glass.

(Problems to be Solved by the Invention) In the wire type window regulator, the wire is stretched between guide members provided at the upper and lower ends of the guide rail that guides the carrier plate. It's summery. Therefore, the direction of the wire is always approximately constant. On the other hand, in the case of a window glass whose front end side rises and falls more than the rear end side, the glass rotates vertically within its plane as it moves up and down. Therefore, if the carrier plate is fixed to the glass, the carrier plate also rotates relative to the vehicle body as the glass moves up and down.

As a result, when the glass is raised and lowered, the wire is bent at the connection to the carrier plate, making the ends of the wire susceptible to fatigue. Therefore, the durability of the wire decreases.

The present invention has been made in view of these problems, and its purpose is to raise and lower the window glass, which rotates within its plane during lifting and lowering, using a wire-type window regulator. , the ends of the wire should not be bent.

Another object of the present invention is to enable the window glass to be raised and lowered smoothly.

(Means for Solving the Problems) In order to achieve this object, in the present invention, a carrier plate supporting a window glass is rotatably attached to the window glass.

The center of rotation of the carrier plate is located on a straight line connecting the locking portions of the wires that are locked at the top and bottom of the carrier plate. Further, the movement locus of the carrier plate is linear.

(Function) With this configuration, the carrier plate can rotate independently from the window glass. Therefore, the carrier plate can be oriented in a constant direction even if the glass rotates in its plane when the glass is raised or lowered.

By moving the carrier plate along a linear locus, the wires can be arranged in a straight line. Further, since the glass is rotated on a straight line formed by the wire, no external force is applied to the wire even when the glass is rotated. Therefore, the wire can be driven smoothly, and the window glass can be smoothly raised and lowered.

(Example) Hereinafter, an example of the present invention will be described using the drawings.

In the drawings, FIG. 1 is an overall schematic view of the wire type window regulator according to the present invention, and FIGS. 2 and 3 are a cutaway front view and a cross-sectional plan view of the main parts of the window regulator.

As is clear from FIG. 1, three rollers 2, 3, and 4 are attached to the lower end of the window glass 1. The center roller 4 has front and rear (first
It is positioned below the rollers 2 and 3 on the left and right sides in the figure.

These rollers 2, 3, and 4 are guided by a guide plate 5 attached to a door panel or the like of the vehicle body. This guide plate 5 has guide portions 6 and 7 formed at its front and rear edges for guiding the front and rear rollers 2 and 3, respectively, and a guide portion for guiding the central roller 4 in the center portion. A hole 8 is provided. The front and rear guide portions 6 and 7 are substantially parallel and inclined toward the lower rear. On the other hand, the guide hole 8, which is the central guide portion, is inclined more rearward than the front and rear guide portions 6, 7. Rollers 2, 3, 4 and guide parts 6, 7
A certain amount of play is provided between the guide hole 8 and the guide hole 8. In this way, the window glass 1 is
The guide portions 6, 8 or 8, where the rollers 2, 4 or the respective mounting positions of the rollers 4, 3 are non-parallel to each other,
7.

When such a window glass 1 is in the highest position as shown by the solid line in FIG. 1, its front and rear edges and upper edge are in close contact with the window frame of the vehicle body, sealing the window. It's becoming like that.
When the glass 1 is lowered from this state, the central roller 4 attached to the lower end of the glass 1 moves into the guide hole 8.
As the glass 1 moves backward while being guided by the glass 1, its front end side descends faster than its rear end side, and as shown by the imaginary line, the glass 1 gradually falls forward. In this way, when the glass 1 is lowered to its lowest position, the glass 1 is housed in the vehicle body with the rear end at a relatively high position, and the window is fully opened.

Further, when the glass 1 in the lowered position is raised, the front end side rises more than the rear end side, and the glass 1 gradually becomes horizontal.

The glass 1 is raised and lowered by a wire 9. The wire 9 is stretched approximately parallel to the rear guide portion 7 by guide members 10 and 11 supported by the vehicle body near the upper and lower rear edge of the guide plate 5, and is engaged with the glass 1 at that portion. It has been stopped. The wire 9 is driven in the longitudinal direction by a drive device 12 provided at a suitable location on the vehicle body.
The drive device 12 is configured such that a pinion that engages with a rack-shaped portion provided on the wire 9 is rotated by a motor 13 or a regulator handle (not shown).

In such a wire type window regulator, when the glass 1 is raised and lowered, the glass 1 rotates within its plane as described above, so the angle between the glass 1 and the wire 9 changes. Therefore, the locking portion of the wire 9 to the glass 1 is configured to be able to rotate relative to the glass 1.

The configuration will be explained in detail with reference to FIGS. 2 and 3.

As is clear from these figures, roller 2,
Reference numerals 3 and 4 have grooves, and the grooves engage with the guide portions 6 and 7 formed by the front and rear edges of the guide plate 5 and the front and rear edges of the guide hole 8, respectively. The upper end of the guide hole 8 has a large diameter, and the roller 4 is attached to the large diameter portion.

These rollers 2, 3, 4 are connected to bolts 14, 15, 1 which are inserted into the lower end of the glass 1 and fixed.
6, respectively. The front bolt 14 and the center bolt 16 are connected by nuts 17 and 18 that sandwich the glass 1 from both sides.
It is designed to be fixed to the glass 1. Also,
The rear bolt 15 is fixed to the glass 1 by sandwiching the glass 1 between the flange 15a and the plate nut 19. The flange 15a of the bolt 15 is pressed down by a roller plate 20 from inside the vehicle body. A cushioning material 21 is provided between the roller 3 and the roller plate 20 to prevent rattling of the glass 1 and to prevent the glass 1 from being curved.
It is also designed to allow for lifting and lowering.

A carrier plate 22 is attached to the end of the rear bolt 15 inside the vehicle body. This carrier plate 22 is locked by a nut 23 that is tightened to the bolt 15, and is rotatably supported by the bolt 15. Both ends of the wire 9 are secured to the upper and lower parts of the center line of the carrier plate 22, that is, the straight line including the bolt 15, which is the center of rotation. In this way, the carrier plate 22 which is the locking part of the wire 9 to the glass 1
is rotatable relative to the glass 1. The glass 1 is supported at an arbitrary height by a wire 9 via its carrier plate 22.

The guide plate 5 has a guide rail 24 parallel to the guide portion 7 on the inside surface of the vehicle body at the rear edge.
is fixed. The carrier plate 22 is adapted to be guided along this guide rail 24. That is, the carrier plate 22 is configured to move along a linear trajectory.
upper and lower guide members 10 over which the wire 9 is stretched;
11 are fixed to the upper and lower ends of this guide rail 24, respectively. And the guide member 1
The wire 9 between 0 and 11 is arranged to pass inside the guide rail 24.

In the wire type window regulator configured in this way, the wire 9 is driven by the drive device 12.
When driven in the longitudinal direction, the wire 9 moves vertically between the guide members 10 and 11. Therefore, the carrier plate 22, which is engaged with the wire 9, moves up and down along the guide rail 24, and the glass 1 moves up and down accordingly. At this time, the glass 1 rotates within its plane as described above,
The carrier plate 22 is rotatable relative to the glass 1, although the angle relative to the wire 9 changes;
Moreover, since the vertical force is applied by the wire 9, the angle of the carrier plate 22 with respect to the wire 9 is kept constant. That is, the portion of the wire 9 that engages the carrier plate 22 will not be bent. Since the direction of the carrier plate 22 is always kept constant in this way, the gap between the carrier plate 22 and the guide rail 24 can be reduced, and the glass 1
can be raised and lowered smoothly.

In the above embodiment, the carrier plate 22 is attached coaxially with the rear roller 3;
can also be attached to the glass 1 separately from the rollers 2, 3, and 4.

(Effects of the Invention) As is clear from the above description, according to the present invention, the carrier plate to which the wire for raising and lowering the window glass is fixed is rotatably attached to the window glass. Even when the glass rotates within its plane as it moves up and down, the carrier plate can always be oriented in a constant direction regardless of the rotation of the glass. Therefore, the wire is no longer bent at the portion where it engages with the carrier plate, and breakage at that portion is prevented.
In this way, a wire-type window regulator for a window glass whose front end side rises and falls more than the rear end side can be made highly durable.

Furthermore, since the movement locus of the carrier plate is a straight line, the wire for moving the carrier plate can be arranged in a straight line. Since the center of rotation of the carrier plate is located on the straight line, even when the glass rotates, the rotational force is prevented from being transmitted to the wire. Therefore, the wire can be driven smoothly, and the window glass can be raised and lowered smoothly.
