Description

[Detailed Description of the Invention] The present invention relates to the structure of attaching a tape to a glass bracket in a tape-type window regulator for an automobile.

In this type of window regulator, a sprocket wheel of a drive unit is engaged with a series of holes in a flexible tape, and the tape slides along a guide, raising and lowering the windshield fixed to the tape, thereby opening the window. This adjusts the opening and closing of the glass.

Conventionally, the tape and the window glass were locked together by simply inserting a pin protruding from a glass bracket fixed to the window glass into a hole in the tape.

In the above-mentioned method of securing the tape and windshield, the pin and tape become unattached due to the load applied to the tape and the distortion and deformation of the pin and associated parts during long-term use. Therefore, there was a possibility that the tape could not be driven.

The present invention provides a tape and windshield locking means that avoids the above-mentioned conventional drawbacks,
The above-mentioned pin has a head at one end, and a portion in which the head engages and slides is attached to the guide.

Since the pin is held at both ends by the glass bracket and its head engaging portion, it is possible to eliminate disengagement of the pin and the tape.

The structure of the tape installation according to the present invention will be explained with reference to the figures below.

In FIG. 1, the upper part 1 is the windshield of an automobile.

A bracket 2 is fixed to the lower edge of this window glass with a rivet 3.

The guide 4 has a curved shape as shown, and the flexible driving tape 5 slides while being guided by the guide 4.

The bracket 2 is fixed to this tape 5.

Therefore, when the tape 5 is slid on the guide 4, the window glass 1 moves up and down in the direction of the arrow, opening and closing the window glass of the automobile door.

Reference numeral 6 on the left side of FIG. 1 is a drive device for the tape 5.

Each of the parts described above is housed in a thin space between the inside panel 7 and the outside panel 8 of the automobile door, as shown in FIG.

Reference numeral 9 at the top of FIG. 1 is an upper bracket for fixing the guide 4 to the inside panel 7, and reference numeral 10 at the bottom of the figure is a lower bracket for fixing the guide 4 to the inside panel 7.

The drive device 6 is fixed to the inside panel 7 by a base 11 (FIG. 2).

The drive device 6 has a handle shaft 12 to which a manual operation handle is attached.

FIGS. 3 and 4 show enlarged views of the drive device.

The base 11 has three elongated holes 13 for use in tightening bolts to the inside panel 7.

The drive device 6 has a configuration as shown in FIG. 4, in which a core 14 is spline-coupled to the drive shaft 12, the core 14 engages with a pinion plate 15, and the pinion plate 15 rotates integrally with the pinion 16. is combined with

The pinion 16 engages with a gear 17, and the gear 17 engages with a pin 19 of a sprocket wheel 18, and is connected to the sprocket wheel 18 in an integral rotational relationship.

Each tooth 20 of the sprocket wheel 18 engages with each hole in the tape 5, as shown at the left end of FIG.

A coiled torsion spring 21 surrounding the outer periphery of the core 14 has both ends bent inward and engages with an axial groove 22 of the core 14, and a finger 15a of the pinion plate 15 is interposed between the two ends. and prevents the well-known windshield from rolling back.

The device is configured.

The torsion spring 21 cooperates with the case 23 surrounding it to prevent backlash.

24 in FIG. 1 is a tape cover.

The above description is about the general structure of this type of window regulator/turbine guide mechanism.

The features of the present invention will be explained below.

5 and 6, the glass bracket 2 is integrally fixed with a U-shaped support piece 26, and a pin 27 is attached to this.
One end portion of is caulked by a caulking portion 28.

The pin 27 passes through the hole 30 of the tape 5 and forms a head 29 at the other end.

The head 29 slides within the sliding groove 25 that the guide 4 has.

31 is a spacer. The left end of the pin 27 in the figure is caulked to the support piece 26 by the caulking part 28, and the right end is caulked to the support piece 26 by the caulking part 28.
9 is held in the sliding groove 25 to secure both ends,
Since the hole 30 of the tape 5 is penetrated in the middle thereof, the engagement between the tape 5 and the glass bracket 2 is reliable and highly reliable, and there is no possibility that the engagement will be disengaged.

As shown in FIG. 7, the left end of the conventional pin 27' is locked to the support piece 26' of the glass bracket 2' by an E ring 32 and a head 33, but the other end remains a free end. .

Therefore, due to deformation or distortion of the surroundings, the free end may come out of the hole 30 of the tape 5, and the tape 5 may disengage from the pin 27'.

The present invention is different from the above-mentioned conventional one in that the head 29 is
The caulking portion 28 can ensure a highly reliable pin-to-tape engagement relationship.
