Description

[Detailed Description of the Invention] The present invention relates to a wire-type automobile window opening/closing device.

In a conventional wire-type automobile window opening/closing device, a pair of wires formed in a loop around a rotating drum are wound or unraveled by operating an operating handle.

For example, as shown in FIG. 1, a carrier plate b fixed to the lower end of a window glass a is supported so as to be movable up and down along a guide rail c, and is wound around a drum e of an operating handle d. The end of one of the wires f is fixed to the upper end of the carrier plate b. Further, the end of the other wire g is fixed to the lower end of the carrier plate b after being wound around a fixed roller h, and the pair of wires f and g are approximately It was arranged in a loop.

However, in the window opening/closing device having the above-mentioned structure, since the entire weight of the window glass a is applied to the wire f, the wire f must be made considerably strong, and a large operating force is required to raise and lower the window glass. There were drawbacks such as the need for

This invention supports the weight of the window glass on the window glass lifting wire by dividing it into two parts, and also supports the lowering wire as it is with a single wire, thereby reducing the operating force when opening and closing the window glass. The present invention aims to provide an automobile window opening/closing device which is designed to equalize the following.

Hereinafter, the present invention will be explained in detail based on an illustrated embodiment.

1, the opening edge of the channel material having a U-shaped cross section is further bent outward at right angles to form the rail portion 1.
It is a rail plate formed with a and 1a, and is arranged vertically so as to be slightly curved toward the outside of the vehicle as a whole, and has a pair of upper and lower brackets 2, 2, and is attached to the door 3 shown by the imaginary line. It is fixed to the inner surface of the inner panel 3a.

Reference numeral 4 denotes a carrier plate having a substantially rectangular plate shape, and the upper half of the carrier plate on the outside of the vehicle is in contact with the inside of the lower end of the window glass 5, and a pin 6 passes through both.
It is fixed with 6.

As shown in FIG. 4, a pair of left and right protrusions 4a, 4a each having an inverted L-shaped cross section and facing inward are provided on the inside surface of the carrier plate 4, and these protrusions 4a, 4a The carrier plate 4 is slidably engaged with the rail portions 1a, 1a of the rail plate 1, respectively, so that the carrier plate 4 is movable in the vertical direction.

The carrier plate 4 in the groove 1b of the rail plate 1 is provided with a pair of left and right guide pieces 4b, 4b, and a guide member having an annular groove 7a on the outer circumferential surface, that is, a pulley 7, is connected to a horizontal axis. 8
It is rotatably supported with.

Reference numeral 9 in FIG. 2 is a winding device attached to the inner panel 3a, which consists of a case 10 having a substantially cylindrical shape with a bottom, and a shaft 1 passing through the case 10.
The drum 12 consists of a pair of large and small drums 12a, 12a, arranged concentrically in parallel with each other and housed in a case 10, and an operation handle 13 attached to the end of the shaft 11 protruding inward of the vehicle. .

The case 10 has wire insertion holes 10 on the upper and lower edges.
a, 10b are provided protrudingly, and after the proximal ends are wound around the drum 12 in opposite directions, each end is wound around the drum 12.
A pair of upper and lower first wires 14 respectively fixed to
The second wire 15 is drawn out from the wire insertion openings 10a and 10b, respectively.

The first wire 14 for pulling up a window glass has its base end wound around a large drum 12a, and its tip end passing through a guide groove 16a of a guide plate 16 attached to the upper end of the rail plate 1. 1 and hangs down, and the pulley 7
After turning the groove 7a by half a turn, the carrier plate 4 is suspended upward by turning the groove 7a upward again, and the tip 14a is prevented from coming off in the chamber 17 of the guide plate 16 in the following manner. There is.

That is, as shown in FIG.
A disk-shaped stopper 19 is fixed to the end of the first wire 14 inserted through the wire insertion port 18 formed in the lower surface of the wire, and the stopper 19 is fitted into the chamber 17 and fixed.

The second wire 15 for lowering the window glass has its base end wound around a small drum 12b whose radius is 1/2 that of the large drum 12a, and its distal end connected to a guide attached to the lower end surface of the rail plate 1. After passing through the guide groove 20a in the plate 20 upward and passing through the wire insertion opening 4c formed in the lower edge of the carrier plate 4, a stopper 21 is fixed to the end thereof.
A chamber 4d formed above the wire insertion port 4c
It is fitted and fixed.

22 and 23 are the first wire 14 and the second wire
This is an outer case that covers the wire 15.

Next, the operation of the automobile window opening/closing device of the present invention constructed as above will be explained.

When the operating handle 13 is turned counterclockwise in FIG. 2, as the first wire 14 is wound around the drum 12a, the pulley 7 moves as a moving pulley, and the pulley 7 moves with half the conventional operating force. When the carrier plate 4 is raised and the window is closed, the second wire 15 is unwound from the drum 12b by half the length of the first wire 14.

In this case, the first wire 14 has 1/2 of the weight of the window glass 5 or a downward external load applied to the window glass (for example, a downward load such as when an elbow is placed on the open window glass 5). It only takes a while.

Conversely, when the operating handle 13 is turned clockwise in FIG. 2, the second wire 15 is wound around the drum 12b, the carrier plate 4 is lowered, the window is opened, and the first wire 14 is teeth,
It is unraveled from the drum 12a.

In the above embodiment, the guide member provided on the carrier plate 4 was a pulley.
For example, a semi-circular guide piece, a shaft-shaped projection, or a semi-circular hole may be formed integrally with the carrier plate, and the wire may be wound around these.

As explained in detail above, in the present invention, the window glass lifting wire and the window glass lowering wire, each of which has its base end wound around the drum of a winding device installed inside the door, are placed inside the door. The winding device is capable of sliding along a rail plate arranged in a substantially vertical direction, and is connected to a carrier plate that supports the window glass, and the winding device winds up one wire and unwinds the other wire. By this,
In an automobile window opening/closing device that raises and lowers a window glass, the intermediate portion of one of the lifting wires, the base end of which is wound around the first drum of the winding device, is inserted into a U-shape from the top of the rail plate. hang in the shape of
The lower part of the wire is wrapped around a guide member provided on the carrier plate, the end is fixed to the upper part of the rail plate, and the base end of the other pull-down wire is connected coaxially with the first drum and one of the ends thereof. Since the wire is wound onto a second drum with a radius of The tensile force of the pulling wire can be halved compared to conventional wires.

Therefore, it is possible to use a relatively thin wire, and if the diameter of the drum in the winding device is the same as that of the conventional one, the window glass can be removed with half the operating force compared to the conventional one. The steering wheel operating force can be reduced without the need for a separate speed reduction device or the like.

Furthermore, when opening a window, the weight of the window glass applies a downward force, so the force needed to pull the window up is smaller than the force needed to pull it up. If the load is pulled by a single wire instead of dividing the load into two as in the case of a wire, the structure of the pulley on the carrier plate can be simplified and costs can be reduced.

Another advantage is that the length of the pull-down wire can be shortened.

Furthermore, when opening and closing a window, the operating force for raising and lowering the window glass can be equalized, and since there is no extreme difference in operating force, the handle can be operated smoothly and conveniently.
