Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a window regulator for an automobile in which a window glass is raised and lowered by a wire. This relates to a wire-type window regulator.

(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 keeping it horizontal, but as in the case of quarter windows, for example, the rear edge of the glass interferes with the rear wheel house, etc. may not be able to be stored. Therefore, in such a case,
The glass is stored in a state where the front end is lowered by raising and lowering the front end or the rear end of the glass.

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

Conventionally, even in the case of a wire-type window regulator for a window glass that is raised and lowered by a large amount from the front end side or the rear end side, the carrier plate has been fixed to the glass.

(Problems to be Solved by the Invention) Incidentally, in a wire-type window regulator, the wire is stretched between guide members provided at the upper and lower ends of a guide rail that guides the carrier plate. . Therefore, the direction of the wire is always approximately constant. On the other hand, in the case of a window glass that rises and falls more greatly than the front end side or the rear end side, the glass rotates vertically within its plane as it moves up and down. Therefore, when 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 such problems, and its purpose is to prevent the end of the wire from being raised or lowered even when a wire window regulator is used to raise or lower a window glass that rotates within its plane when it is raised or lowered. This is to prevent the parts from being bent.

Means for Solving the Problems To achieve this object, the invention provides for a carrier plate supporting a window glass to be rotatably mounted relative to the window glass.

(Function) By configuring as described above, the: 1- Yarya plate can be rotated independently from the window glass. Therefore, the carrier plate can be oriented in a constant direction even when the glass rotates in its plane when the glass is raised or lowered.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

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

As is clear from the diagram, three rollers 2, 3.4 are attached to the lower end of the window glass 1. The roller 4 in the center is connected to the rollers 2 on the front and rear (left and right in Figure 1).
, 3.

These rollers 2, 3.4 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 by its front and rear edges for guiding the front and rear rollers 2 and 3, respectively, and has guide portions 6 and 7 formed in the center thereof.
A guide hole 8 for guiding the central roller 4 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 central guide hole 8 is inclined more rearward than these guide portions 6.7.

When such a window glass l 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 looks like this. When the glass 1 is lowered from this state, the central roller 4 attached to the lower end of the glass 1
As the glass l is guided by the guide hole 8 and moves rearward, it descends faster than the front end or the rear end, and as shown by the imaginary line, the glass l is gradually lowered. Become. 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 l is raised and lowered by a wire 9. This wire 9 connects to a guide member 1 supported by the vehicle body near the upper and lower rear edges of the guide plate 5.
0.11, it extends approximately parallel to the rear guide portion 7, and is locked to the glass l at that portion. The wire 9 is connected to a drive device 1 installed at a suitable location on the vehicle body.
2 to be driven in the longitudinal direction.

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 ([4 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 glass l of the wire 9
The locking portion is rotatable relative to the glass l.

Its configuration will be explained in detail with reference to FIG. 2.3.

As is clear from these figures, the rollers 2° 3.4 are grooved, and the grooves are formed on the front and rear edges of the guide portions 6, 7 and the guide hole 8 formed by the front and rear edges of the guide plate 5. They are adapted to engage with each other. Guide hole 8
The upper end has a large diameter, and the roller 4 is attached to the large diameter portion.

These rollers 2, 3.4 are supported by poles 14, 15, 16, which are inserted through and fixed to the lower end of the glass 1, respectively. The front port 14 and the center port 16 are Nara) 1 that sandwich the glass 1 from both sides.
7.18, it is fixed to the glass 1. In addition, the rear pole) 15 has its flange 15a
By sandwiching the glass 1 between the plate nut 19 and the plate nut 19, it is fixed to the glass 1.

The flange tSa of the port 15 is the roller plate 2
0 is being pressed down from inside the car body. A cushioning material 21 is provided between the roller 3 and the roller plate 20 to prevent the glass 1 from wobbling and also to allow the curved glass 1 to move up and down.

A carrier plate 22 is attached to the inner end of the rear port 15 on the vehicle body. This carrier plate 2
2 is locked by a nut 23 that is tightened to the port 15, and is rotatably supported with respect to the port 15. Both ends of the wire 9 are secured to upper and lower portions of the carrier plate 22 on the center line. Thus, wire 9
The carrier plate 22, which is a locking part to the glass 1,
It can be rotated relative to the glass l. The glass l then passes through its carrier plate 22 to the wire 9
It can be supported at any height.

A guide rail 24 parallel to the guide portion 7 is fixed to the rear end edge of the guide plate 5 on the inside surface of the vehicle body. The carrier plate 22 is guided along this guide rail 24. Upper and lower guide members 10.11, over which the wire 9 is stretched, are fixed to the upper and lower ends of this guide rail 24, respectively. The wire 9 between the guide members 10 and 11 passes through the guide rail 24.

In the wire-type window regulator configured in this manner, when the wire 9 is driven in the length direction by the drive device 12, the wire 9 moves in the vertical direction between the guide members to and it. Therefore, the wire plate 22 locked to the wire 9 is attached to the guide rail 2.
4, and the glass 1 is raised and lowered accordingly.

At this time, the glass l rotates within its plane as described above,
Although the angle with respect to the wire 9 changes, the angle of the carrier plate 22 with respect to the wire 9 remains constant because the carrier plate 22 is rotatable with respect to the glass l and the vertical force is applied by the wire 9. drooping 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 moved up and down smoothly. .

In the above embodiment, the carrier plate 22 is attached coaxially with the rear roller 3;
It is also possible to attach it to the glass 1 separately.

(Effects of the Invention) As is clear from the above description, according to the present invention, the carrier plate on which the wire for raising and lowering the window glass is fixed is rotatably attached to the window glass. Even when the glass rotates in its plane as it is raised and lowered, 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, it is possible to make a highly durable wire-type window regulator for a window glass that rises and falls more significantly from the front end side or the rear end side.
