Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile window glass lifting device using a wire, and in particular to a structure of a fixing portion at the end of the wire.

Conventionally, in automobile window glass lifting devices using wires, a means is provided to apply a required tension to the wires in order to prevent the wires from loosening due to dimensional variations during component manufacturing or wire elongation due to aging. ing.

For example, as shown in FIG.
The distal end portion of the first wire b whose proximal end portion is wound up is
After winding the fixed pulley d at the upper end of the guide rail c, the second wire f, which is fixed to the carrier plate e and symmetrical thereto, has its base end wound around the winding drum a, and its tip end After winding around a fixed pulley g, the part is fixedly attached to a carrier plate e. A flexible outer case h is fitted into the intermediate portions of the first wire b and the second wire f, and between one end surface of the outer case h and the side edge of the guide rail c. The structure was such that compression coil springs j were each compressed.

When installing the wire, these compression coil springs
By compressing the wires, each wire is loosened, and each wire is wound around the fixed pulleys d and g. After installation, the effective distance of the outer case h is set by the biasing force of the compression coil spring j. By increasing the tension, the wire was prevented from loosening and tension was applied to the wire.

However, with such a structure, when the handle is operated, the compression coil spring j is compressed before the carrier plate moves, reducing the effective distance of the outer case h, resulting in so-called play in the handle. In addition, each time the outer case h moves within the door, it collides with the window glass or door panel, causing unpleasant noises.

The present invention was made to eliminate the above-mentioned drawbacks, and a caulking metal fitting with a groove cut therein is fitted into a window hole drilled in a rail plate or a carrier plate, and the end of the wire is inserted into the groove. An object of the present invention is to provide an automobile window glass lifting device which simplifies the work of attaching wires by caulking and fixing the wires in a tensioned state.

Reference numeral 10 denotes a winding device, which has a substantially horizontal triangular shape and has a substrate 11 with a rising wall 11a on the outer periphery.
It consists of a mounting plate 12 attached to the base plate 11 with three legs, and a winding drum 14 housed within the base plate 12 and attached to a shaft 13 passing through the base plate 11 and the attachment plate 12. An operating handle 15 is attached to the end of the winding drum 14 on the inside of the vehicle.

In addition, there are rising walls 1 at the upper and lower corners of the board 11.
Bushes 16 and 16 made of an elastic material are respectively attached to the notches 1a.

Reference numeral 17 shown in Fig. 3 is a caulking metal fitting, in which the upper surface of the cubic main body 17a is chamfered in four directions in a trapezoidal shape, a narrow groove 17b is cut in the longitudinal direction in the center, and a wide groove is formed on the back surface. It is provided with a rectangular flange portion 17c.

As shown in FIG. 2, rectangular window holes 18, 18 are formed on the right side of the upper and lower ends of the rail plate 1, and the caulking metal fittings 17 are inserted into each window hole 18 from the back side. A narrow groove 17b is exposed on the front side of the rail plate 1.

The proximal end of the first wire 19 for pulling up the carrier plate 2 is wound around the winding drum 14, and then its end is fixed to the winding drum 14, and the free end is connected to the winding drum 14. After passing through the bush 16 and being inserted into the guide groove 6 of the upper guide plate 7, it heads downward, wraps around the lower half of the pulley 4, and then heads upward again.
7b, the end portion 19a slightly protrudes from the rail plate 1, and while pulling the end portion 19a and applying tension to the wire, the narrow groove 17 of the caulking fitting 17 is pulled.
The first wire 19 is fixed to the rail plate 1 by caulking b with an appropriate tool (not shown).

Similarly, the proximal end of the second wire 20 for pulling down the carrier plate 2 is attached to the winding drum 14.
After being wound in the opposite direction to the first wire 19,
The end thereof is fixed to the winding drum 14, and the free end passes through the lower bush 16, is inserted into the guide groove 8 of the lower guide plate 9, and then heads upward.
After winding the upper half of the pulley 4, it heads downward again, and after passing through the narrow groove 17b of the caulking fitting 17,
The terminal portion protrudes slightly from the rail plate 1, and the second wire 20 is fixed to the rail plate 1 by pulling the terminal portion 19a and caulking the narrow groove 17b of the caulking fitting 17 while applying tension to the wire. (See Figures 4 and 5).

Note that 21 is a wire end member fixed to the final ends of the first wire 19 and the second wire 20, and 22 and 23 are outer cases that cover the intermediate portions of the first wire 19 and the second wire 20, respectively. It is.

The operation of the automobile window opening/closing device configured as above will be explained.

Turn the operating handle 15 clockwise in Figure 2,
When the first wire 19 is wound onto the winding drum 14,
By rotation of the shaft 13, the second wire 20 is uncoiled from the winding drum 14, the carrier plate 2 is pulled upwards and the window of the motor vehicle door is closed.

Conversely, if you turn the operating handle counterclockwise,
the second wire 20 is wound on the winding drum 14;
The first wire 19 is unraveled, the carrier plate 2 is lowered, and the window of the motor vehicle door is opened.

The operation handle tends to become loose after long-term use, but in the automobile window opening/closing device according to the present invention, the required tension is applied to the first wire and the second wire in advance during assembly. After being applied, the end is fixed to the rail plate with caulking metal fittings, so it is unlikely to come loose.

What is shown in FIGS. 6 and 7 differs from the first embodiment described above in that the ends of the first wire and the second wire are directly fixed to the carrier plate 24 without using the pulley 4 on the carrier plate 2. This is a second embodiment of the present invention having a similar structure, and the same parts will be described using the same reference numerals.
