DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window regulator for raising and lowering a window glass for opening and closing a window formed in a vehicle door in the vertical direction of the door.

[0002]

2. Description of the Related Art Conventionally, as this type of window regulator device, one disclosed in Japanese Patent Application Laid-Open No. Hei 9-119260 is known. The lift arm includes a lift arm having one end linked to the window glass and rotatably supported on the door panel via a base plate, a sector gear fixed to the other end of the lift arm, and a pinion gear supported by the base plate and meshing with the sector gear. And a driving mechanism.

In this conventional apparatus, the lift arm is rotated via a sector gear meshing with the pinion gear by the rotation of the pinion gear by the operation of the drive mechanism, whereby the window glass is raised and lowered in the vertical direction of the vehicle door, and the vehicle door is moved up and down. The windows are opened and closed.

Further, in the conventional apparatus, the sector gear and the lift arm are fixed to each other by inserting a projecting portion formed in the sector gear by half punching into a through hole formed in the lift arm and caulking the tip (diameter of the through hole). Plastic deformation so as to be larger than that).

[0005]

However, in the above-mentioned conventional apparatus, the sector gear and the lift arm are fixed by caulking, but their strength is not sufficient. In particular, when the lift arm is thinned, its strength is reduced. May be further reduced. Therefore, there is a limit to the thickness of the lift arm, and in order to further reduce the thickness of the lift arm, it is necessary to improve the strength of the fixing portion.

Therefore, an object of the present invention is to improve the strength of a fixed portion between a lift arm and a sector gear.

[0007]

The technical means taken in the present invention to solve the above-mentioned technical problems includes a through hole formed at one end of a lift arm, and a half hole formed in a sector gear, and a through hole formed in a sector gear. A projection that is inserted and the tip is caulked against the through hole, supports the drive mechanism and the lift arm on a door panel, and holds the lift arm in cooperation with the sector gear from the tip side of the projection. And a base plate.

According to this technical means, the fixed portion of the lift arm with the sector gear is sandwiched between the sector gear and the base plate. Therefore, the deformation of the lift arm can be suppressed, and the strength of the portion can be improved.

More preferably, a plurality of the protrusions are formed at predetermined intervals along the arc shape of the tooth portion of the sector gear.

[0010] More preferably, the protrusion and the through hole are arranged around a center of a support portion of the lift arm to the base plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a lift arm 2 is rotatably supported at its base end by a pin 3 on a base plate 1 fixed to a door panel (not shown) of a vehicle door. ing. The tip of this lift arm 2
It is slidably supported via a roller 6 on a rail 9 fixed to the lower part of a window glass 8 which moves up and down in the door up-down direction (the up-down direction in FIG. 1) to open and close the window of the vehicle door.
A pin 4 is provided upright at the approximate center of the lift arm 2 in the longitudinal direction, and two equalizer arms 5 and 7 are rotatably supported at one end of the pin 4. The other end of the equalizer arm 5 is slidably supported on a rail 9 via a roller 5a, and the other end of the equalizer arm 7 is mounted on a rail 10 fixed to a door panel.
It is slidably supported via a. Rails 9, 10
Extend parallel to each other in a door front-rear direction (left-right direction in FIG. 1) orthogonal to the door vertical direction.

Lift arm 2, equalizer arms 5, 7
Are made of a thin plate (0.8 mm thick) of a high-tensile steel material, are formed with innumerable irregularities, are subjected to so-called staring, and are increased in strength. Also, plating is applied to prevent rust.

A drive mechanism 11 is supported on the base plate 1. The drive mechanism 11 includes a well-known motor and a manual handle, and a pinion gear 12 (shown in FIG. 2) that is rotated by the operation of the motor and the manual handle.
It has.

As shown in FIGS. 2 and 4, a sector gear 13 is fixed to the base end of the lift arm 2 in a structure described later. The sector gear 13 is made of a galvanized steel plate and meshes with the pinion gear 12 at its arcuate teeth 13a. The rotation of the pinion gear 12 causes the lift arm 2 to rotate integrally around the pin 3.

As shown in FIGS. 2 to 4, a shaft stopper 21 (through which the pin 3 is inserted) at the base end of the lift arm 2 has three pins equally spaced around the pin 3. A through hole 22 is formed. In the sector gear 13,
An arm-shaped mounting portion 13b overlapped on the shaft stopper 21 is formed to extend from the arc-shaped tooth portion 13a. This mounting portion 13b
Is provided with a through hole 14 through which the pin 3 penetrates, and three projections 15 arranged equally around the through hole 14 similarly to the through hole 22.
Are formed half-blanked. Projection 15 of sector gear 13
Is inserted into the through hole 22 of the lift arm 2 and its tip is swaged. As a result, the sector gear 13 is fixed to the lift arm 2. As shown in FIG. 4, the mounting portion 13b of the sector gear 13 is
The lift arm 2 is clamped from the caulking side of the projection 15 in cooperation with the base plate 1 in a state where the projection arm 15 is superposed. Thereby, the strength of the shaft stopper 21 of the lift arm 2 is increased. In addition, around the pin 3 of the lift arm 2,
A circular beat 23 is formed, and the beat 23 contacts the base plate 1. Thereby, surface contact between the shaft stopper 21 of the lift arm 2 and the base plate 1 is avoided, and the rotation of the lift arm 2 is facilitated. The beat 23 may be formed on the base plate 1 and abut the shaft stopper 21 of the lift arm 2.

As shown in FIG. 5, the fixing of the sector gear 13 to the lift arm 2
A base end other than 1 may be used. Further, a plurality of projections 15 may be formed in the arc tooth portion 13a of the sector gear 13 so as to be arranged along the arc shape. Thereby, the fixing position of the lift arm 2 to the sector gear 3 can be freely set along the arc shape of the arc tooth portion 13a, and the initial angle of the lift arm 2 to the sector gear 13 can be freely set according to the size of the vehicle door to be mounted. Can be set to

[0017]

According to the present invention, the sector gear is fixed to the lift arm by inserting the protrusion formed in the sector gear into the through hole formed in the lift arm and caulking the tip thereof, so that the conventional gear is fixed to the lift arm. Adhesion by welding can be eliminated. Thereby, the thickness of the lift arm can be reduced, and the weight and cost can be reduced.

Further, according to the present invention, since the lift arm is sandwiched between the sector gear and the base plate, the strength of the fixed portion between the lift arm and the sector gear can be improved, and the lift arm can be made thinner. It becomes possible.
