Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a regulator handle drive section of a window regulator for an automobile or the like.

Conventionally, there are two types of window regulators: link type and wire type. For example, the wire type window regulator of the following type is shown in Figs. 1 and 2.
In order to move the window glass 3 up and down along the window sash 2 provided in the door 1, a flexible core wire 7 is placed in the door interior space 6 between the door inner panel 4 and the door outer panel 5. A flexible wire 9 for transmitting driving force for raising and lowering a window glass, which is formed by winding a coil 8 spirally to form a rack, is guided by a wire guide tube LO and attached to the door inner panel using a suitable mounting bracket 11. It is fixed at 4.

The flexible wire 9 is connected to the lower end of the window glass 3 by a connecting fitting 12, and the continuous fitting 12 is connected to a wire guide tube 1 extending parallel to the window sash 2.
It is guided by a slit 13 of 0. Further, a pinion gear 14 is engaged with the other end of the flexible wire 9, and this pinion gear 14 is connected to the regulator handle 1.
Flexible wire 9 by rotating by 5
The wire guide tube 10 is driven longitudinally into the wire guide tube 10 and the window glass 3 is pulled up or pushed down via the connecting fitting 12, thereby raising and lowering the window glass 3 along the window sash 2 to open and close the window. Conventionally, as shown in FIG. 3, in the handle drive section of the above-mentioned wire-type window regulator, the regulator pinion gear 14 is integrally fixed to the shaft 16 of the regulator handle 15 by sliding or other means. is rotatably supported by the gear case 17, the wire guide tube 10 is coupled to the gear case 17, and the regulator pinion gear 14 is engaged with the rack portion of the flexible wire 9, thereby connecting the regulator pinion gear 14 and the regulator handle shaft 16. , a gear case 17 are assembled with the wire guide tube 10, and a handle shaft 16 protrudes from the gear case 17.

Therefore, when installing such a window regulator on a door, the window regulator is inserted into the door interior space 6 through the window glass entry/exit gap 18 that closes between the upper ends of the door inner panel 4 and the door outer panel 5, and is assembled. As shown in Figure 1,
It is necessary to provide a working hole 19 in the door inner panel so that the window regulator can enter and exit the door interior space 6, which results in a very disadvantageous structure in terms of the door layout and rigidity. There was a problem. In view of the above-mentioned points, an object of the present invention is to provide a structure in which the regulator handle shaft and the pinion gear shaft can be separated and retrofitted separately, thereby reducing the thickness of the handle drive section that is assembled integrally with the wire guide tube. This allows the window regulator to enter and exit the door interior space using the door window glass entry/exit gap, and by reducing or eliminating the door working hole, the door layout and door This is an attempt to resolve problems with the rigidity of the inner panel.

The invention will now be explained with reference to the drawings.

FIG. 4 is an enlarged sectional view showing an example of a window regulator handle drive unit according to the present invention. The gear shaft 20 is made of a hollow shaft, the pinion gear 14 is fixed integrally to this using a competitive bonding brush, and both ends of the gear shaft are attached to both side walls 17 of the gear case 17.
The gear shaft 20 is rotatably supported by the support holes 22a and 22b formed in the gear shafts 20a and 17b, and is attached so as not to come off by engaging with the stepped portions 23a and 23b.
The length A is large enough to enter and exit the door upper gap 18,
Preferably, the length A of the gear shaft 20 is smaller than the dimension B of the upper gap 18.

Reference numeral 24 denotes a notch groove (see FIG. 6) formed at one end of the gear shaft 20, which is provided for holding a locking clip 25 in the notch groove 24 and locking the handle shaft 21 as described later. ing.

The handle shaft 21 has serrations cut at both ends 21a and 21b, and a circumferential groove 26 for clip engagement is formed in the center to provide a small diameter portion.
1 into the hollow shaft hole 27 of the gear shaft 20, the serrations of the end portion 21a bite into the inner peripheral wall of the bore hole 27 to prevent relative rotation between the gear shaft 20 and the handle shaft 21. The elastic locking clip 25 installed in the cutout groove 24 of the gear shaft 20 elastically enters the circumferential groove 26 on the handle shaft 21, so that the handle shaft 21 is held in a predetermined position against the two gear shafts. Configure so that it can be locked. In FIG. 5, a cutout groove 24 is provided at the end, that is, the inner end, of the gear shaft 20, the handle shaft 21 is correspondingly lengthened, and an elastic locking clip 25 is engaged with the inner end of the handle shaft 21. A circumferential groove 26 is provided, and the gear shaft 2
0 and the handle shaft 21 are engaged with each other by a spline 28.

7 shows an example in which the handle shaft 21 shown in FIG. 5 is provided with a rectangular section 29 instead of the spline 28, and FIG. 8 shows an example in which a key 30 is also provided.

The present invention is not limited to the above-mentioned wire type window regulator, but, for example, as shown in FIG. The same can be applied to a handle drive part of a link type window regulator (not shown) that engages with the handle drive part of the link type window regulator.

According to the present invention, since it is possible to enter and exit the window regulator into the interior space of the door using the gap for entering and exiting the window glass of the door, the window regulator mounting hole is provided in the door inner panel. 4. It is also possible to eliminate the work hole, which eliminates the restriction of the door layout by the installation work hole, and also eliminates the disadvantage of reducing the rigidity of the door inner panel. .
