Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a wind regulator for a vehicle, particularly a manual wind regulator.

Conventional technology Conventionally, this type of wind regulator is disclosed in "Automotive Engineering Complete Book, Volume 10, Passenger Car Body", published by Sankaido Co., Ltd., April 20, 1981, pages 134 to 137. There are link type and wire type types. Therefore, to explain this wire-type one as shown in FIG. 5, this window regulator has a drive section 2 that raises and lowers the window glass 1, and a manual handle 3 that drives this drive section 2.
(hereinafter simply referred to as the handle).
The drive unit 2 includes a guide rail 4 vertically fixed to the vehicle body inner panel A, a slider 5 attached to the guide rail 4 so as to be vertically slidable, and one side of the guide rail 4 on the vehicle body inner panel A. Base plate 6 fixed to the part located at
and a drum 7 that is pivoted on this base plate 6.
and a wire 8 which is fixed to the slider 5, has both ends wound around the upper and lower pulleys 4a, 4b of the guide rail 4, and is wound around the drum 7 multiple times in opposite directions and moored.

By the way, some of this type of wind regulators are disclosed in Japanese Utility Model Application Publication No. 54-21326 and Japanese Utility Model Application Publication No. 56-1989.
As disclosed in Japanese Patent No. 121862, the drive shaft that connects the drive part and the handle is divided into a drive-side shaft connected to the drive part and a handle-side shaft integrally formed with the handle, and these drive-side shafts The end of the shaft and the end of the handle-side shaft are coaxially fitted while being prevented from rotating, and a retaining member is attached across this fitted part, so that the two shafts are assembled into one body. Are known.

Problems to be Solved by the Invention In a wind regulator, the above-mentioned drive shaft is divided into a drive side shaft and a handle side shaft, and these two shafts are coaxially fitted and assembled together while being prevented from rotating. By forming a spline hole in the axial center of the end face of one split shaft, forming a spline shaft part in the end of the other split shaft, and male-femally fitting the spline shaft part into the spline hole, It is necessary to fit the two divided shafts together while preventing them from rotating coaxially. Therefore, when fitting the end of the handle-side shaft to the end of the drive-side shaft located at the back of the insertion hole formed in the interior material assembled to the door, the spline shaft and the spline hole must be connected. After adjusting the position so that the spline shaft part and the spline hole are coaxial and aligning the spline shaft part and the spline hole so that the many uneven lines of the spline hole are aligned as a whole, the spline shaft part must be pushed into the spline hole, There is an inconvenience that this combination work requires a great deal of effort and time.

Means for Solving the Problems In the present invention, a circular alignment hole is formed at the axial center of the end face of the divided driving shaft, and a non-circular locking hole is formed at the axial center of the bottom face of the alignment hole. At the same time, a center shaft portion is formed at the end of the divided handle-side shaft to fit with the alignment hole with substantially the same diameter, and a center shaft portion of the center shaft portion is fitted into the center portion of the distal end surface with substantially the same shape as the locking hole. A locking protrusion is formed that matches the alignment hole and has a protrusion less than the depth of the alignment hole.

Function When assembling the handle-side shaft to the drive-side shaft, insert the center shaft of the handle-side shaft into the alignment hole of the drive-side shaft with the locking protrusion at the beginning, and a part of the center shaft of the handle-side shaft is inserted into the alignment hole. When the locking protrusion comes into contact with the bottom of the alignment hole, while applying a slight pushing force to the handle-side shaft, slowly rotate the handle-side shaft in the circumferential direction around the center shaft that fits into the alignment hole. Rotate to find the connection between the locking protrusion and the locking hole, and when the locking protrusion meets the locking hole, push the handle-side shaft. As a result, the locking protrusion fits into the locking hole, and the entire center shaft portion fits into the alignment hole, and is coaxially fitted into the handle-side shaft and the drive-side shaft while being prevented from rotating.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, in which the same parts as the conventional structure are denoted by the same reference numerals.

In FIGS. 1 and 2, the drive shaft 9A is divided into a drive shaft 15 and a handle shaft 16. This drive side shaft 15 includes
A drum 7 of the drive unit 2 and a clutch 10 for preventing reverse rotation are attached. The clutch 10 includes a core 11 fixed to the outer periphery of a drive shaft 15, a cover 12 fixed to the base plate 6 and having a cylindrical portion 12a forming a housing chamber for the core 11, and a cylindrical portion of the cover 12. a coil spring 13 which is housed between the inner periphery of the core 12a and the outer periphery of the core 11 and has bent portions 13a at both ends folded into notches 11a carved in the axial direction on the outer periphery of the core 11; and the drive portion. A flange 14a connected to the end of the drum 7 on the inside side of the vehicle interior, rotatably fitted to the drive shaft 15, and bent on one side is sandwiched between the bent portions 11a of the coil spring 13. It consists of a supporter 14. Therefore, when the driving shaft 15 is rotated, the driving shaft 15 and the core 1
1, the driving force is transmitted in this order to the supporter 14, the drum 7, and the wire 8, and the coil spring 13
The slider 5 is moved up and down by the guide rail 2, and the window glass 1 is moved up and down. Conversely, in response to the dead weight applied to the windshield 1 or an external force trying to lower it, the external force is transmitted to the slider 5, the wire 8, the drum 7, and the supporter 14 in this order, and the flange 14a of the supporter 14 is connected to the bent portion of the coil spring 13. Press 13a,
A force is applied in the direction of enlarging the outer diameter of the coil spring 13, and the friction between the coil spring 13 and the outer periphery of the cylindrical portion 12a of the cover 12 applies a brake, preventing the windshield 1 from sliding down. ing.

The driving shaft 15 includes a shaft portion 17 on which the drum 7 of the driving portion 2 and the supporter 14 of the clutch 10 are rotatably fitted, and a core 1 of the clutch 10 made of zinc die-casting adjacent to the shaft portion 17.
1 and a receiving part 19 adjacent to the knurled part 18 and rotatably inserted into the cover 12 of the clutch 10. A circular alignment hole 20 is provided at the axial center of the end surface of the receiving portion 19, a non-circular locking hole 21 is formed at the axial center of the bottom surface of the alignment hole 20, and the opening of the alignment hole 20 is connected to the circular alignment hole 20. A edging hole 22 with a larger diameter than that is provided. Two long holes 24 are formed in the circumferential wall of the edging hole 22 so as to face each other in the radial direction and open substantially flush with an annular stepped surface 23 communicating with the edging hole 22 and the alignment hole 20.

On the other hand, the handle-side shaft 16 is made of hard synthetic resin integrally molded on the back surface of the base of the handle 3A, and includes, in order from the handle 3A side toward the tip, the large-diameter portion 25 inserted into the edge hole 22, the alignment a central shaft portion 26 that is fitted with approximately the same diameter as the hole 20;
and a locking protrusion 27 that is fitted in substantially the same shape as the locking hole 21. The amount of protrusion of this locking protrusion 27 is smaller than the depth of the alignment hole 20, as shown by the imaginary line in FIG. This locking protrusion 27
The fitting between the locking hole 21 and the locking hole 21 constitutes a rotation preventing means. A receiving groove 28 corresponding to the elongated hole 24 is formed in an annular shape on the circumferential surface of the boundary between the large diameter portion 25 and the center shaft portion 26 .

Reference numeral 30 indicates a retaining member made of an elastic material that is attached to the outer periphery of the receiving portion 19, and has locking members at both ends thereof that protrude in the axial direction from the inner periphery of the alignment hole 20 through the elongated hole 24. A portion 31 is formed.

According to the structure of the above embodiment, the base plate 6 on which the drum 7, clutch 10, and drive shaft 15 are assembled is brought between the vehicle body inner panel A and the vehicle body outer panel (not shown), and the drive shaft 15 is moved. After inserting the base plate 6 into the escape hole of the vehicle body inner panel A and fixing the base plate 6 to the outer surface of the vehicle body inner panel A with screws (not shown), hold the handle 3A and insert the handle side shaft 16 with the locking protrusion 27 first. By pushing it into the alignment hole 20 through the edge hole 22 of the drive side shaft 15 from an insertion hole (not shown) made corresponding to the tip of the drive side shaft 15 of the interior material B covering the inner surface of the vehicle body inner panel A. After the locking portion 31 of the retaining member 30 is pushed outward on the tapered surface 26a of the center shaft portion 26 of the handle-side shaft 16, the center shaft portion 2
6, a part of the center shaft part 26 fits into the alignment hole 20, and the distal end surface of the locking protrusion 27 fits into the alignment hole 20, as shown by the imaginary line in FIG.
is located at the entrance of the locking hole 21, in contact with the bottom surface of the locking hole 21. Therefore, while softening the pushing force to the handle-side shaft 16 and applying a slight pushing force to the handle-side shaft 16, the handle-side shaft 16 is moved in the circumferential direction around the center shaft portion 26 fitted in the alignment hole 20. Slowly rotate the locking protrusion 27 and the locking hole 21, and when the locking protrusion 27 meets the locking hole 21, push the handle-side shaft 16 again to lock it. The protrusion 27 fits into the locking hole 21, and the retaining member 30
The locking portion 31 is locked across the receiving groove 28 and the elongated hole 24, and the drive side shaft 15 and the handle side shaft 16 have a rotation prevention function by fitting the locking protrusion 27 and the locking hole 21. It is coaxially assembled with a pull-out prevention function by the pull-out prevention member 30, and the driving force centered on the drive shaft 9A of the handle 3 is transmitted to the handle-side shaft 16, the drive-side shaft 15, the drum 7, and the wire. 8 in order, the window glass 1 can be raised and lowered.

In addition, the presence of the alignment hole 20 into which the center shaft portion 26 of the handle-side shaft 16 is fitted prevents rattling at the connecting portion of the two shafts 15 and 16 on the handle-side and drive-side, thereby preventing the handle-side shaft 16 from wobbling. There is no problem with rotational operation.

Furthermore, when assembling the drive unit 2 and interior material B to the vehicle body inner panel A, the drive side shaft 1
Since the amount of protrusion from the vehicle body inner panel A of the drum 7, the clutch 10, and the drive shaft 15 is much smaller than the protrusion dimension of a single drive shaft from the vehicle body inner panel A, the drum 7, clutch 10, and drive shaft 15 are assembled. By bringing the base plate 6 between the vehicle body outer panel (not shown) and the vehicle body inner panel A, the tip of the drive shaft 15 can be easily inserted into the escape hole of the vehicle body inner panel A, and the interior material B can be inserted into the vehicle body inner panel. The moving distance for overlapping the panel A with the driving shaft 15 as a reference becomes shorter, and the work becomes easier.

Here, in the above embodiment, the wire type was explained as an example, but in the case of the link type, as shown in FIGS. This can be applied by replacing the pinion gear 7A that meshes with the sector gear 34 provided in the drum 7 of the above embodiment.

Effects of the invention As described above, according to the invention, the alignment hole is formed in a circular shape, the center shaft portion is formed to have approximately the same diameter as the alignment hole, and the amount of protrusion of the locking protrusion is made smaller than the depth of the alignment hole. Therefore, when fitting the drive side shaft and the handle side shaft, insert the locking protrusion and the center shaft part into the alignment hole, and when the locking protrusion comes into contact with the bottom of the alignment hole,
While softening the pushing force applied to the handle-side shaft, slowly rotate the handle-side shaft around the center shaft fitted in the alignment hole to find the connection between the locking protrusion and the locking hole, and then When the locking protrusion meets the locking hole, the handle-side shaft can be pushed in, making it easier to engage the locking hole with the locking protrusion that prevents rotation of the drive-side shaft and handle-side shaft. .

In addition, since the center shaft portion is formed to have approximately the same diameter as the alignment hole, when the drive side shaft and handle side shaft are coaxially fitted while being prevented from rotating,
By fully fitting the alignment hole and the center shaft portion, it is possible to prevent rattling at the connecting portion between the drive side shaft and the handle side shaft. In addition, a non-circular locking hole is formed at the axial center of the bottom surface of the alignment hole, and a locking protrusion that fits in the locking hole in approximately the same shape is formed at the axial center of the end surface of the central shaft. By forming the stop hole and the locking protrusion to a maximum size smaller than the alignment hole and the center shaft portion, the mechanical strength of the connecting portion between the drive side shaft and the handle side shaft can be strengthened, and thus , the function of raising and lowering the window glass can be fully demonstrated.

Furthermore, the amount of protrusion of the drive-side shaft connected to the drive section is made shorter than the amount of protrusion of a conventional drive shaft with a single configuration, making it easier to assemble the drive section to the inner panel of the vehicle body, and improve the ease of assembling the drive section to the inner panel of the vehicle body. The durability of the rotating parts of the drive shaft has been improved by improving the assemblability of the materials, by making the drive side shaft which requires a rotatable fitting part made of metal, and by constructing the handle side shaft from synthetic resin. Another advantage is that weight reduction can be achieved while ensuring smoothness.
