Description

[Detailed Description of the Invention] This invention relates to a window regulator that raises and lowers the curved windshield of an automobile.

Conventionally, an automobile window regulator generally has a structure shown in FIGS. 1 and 2, in which both the front and rear sides of the lower end of a windshield 1 are press-fitted and fixed into a glass holder 2, and the glass holders 2, 2 are attached to a movable guide rail 3. It is fixed to the upper end fixing surfaces 3a on both the front and rear sides, and the upper ends of the first arm 4 and the second arm 5, which are the guide rails 3 combined in an X shape, are slidably locked, and the lower end of the first arm 4 is fixed. The provided fan-shaped rack 6 is engaged with a pinion (not shown) rotated by a bundle shaft 7, and the lower end of the second arm 5 is slidably latched to a static guide rail 8 fixed to a door panel (not shown). By rotating the fan-shaped rack 6 by operating the bundle, the window glass 1 is raised and lowered to open and close the window.

Incidentally, recently, window glasses with a large curvature have been adopted for design reasons.

If a windshield with a large curvature is used, the movement guide rail will move around the windshield because the conventional window regulators described above do not take into account movement in the direction perpendicular to the windshield (i.e., in the vehicle width direction). It cannot be used because it cannot follow.

Therefore, if each part is provided with play, especially if the play is large in the vehicle width direction, it is possible to raise and lower the vehicle, but the value as a product is low and it cannot be used practically.

This idea was made in view of the above problems,
The support piece fixed to the window glass holder and the movable guide rail are provided with curled parts in a staggered manner through which pins are rotatably inserted, so that the movable guide rail can be freely rotated with respect to the support piece in a direction substantially perpendicular to the windshield. It is an object of the present invention to provide a window regulator for an automobile that absorbs the curvature of the windshield and allows the curved windshield to move up and down smoothly.

This invention will be explained in detail below with reference to embodiments shown in the drawings.

In FIG. 3, glass holders 11, 11 are attached to the lower ends of both the front and rear sides of the windshield 10, which has a large curvature.
The supporting pieces 12.degree. 12 are rotatably connected to both the front and rear sides of the movable guide rail 13 via pins 14.

The glass guide 11 has a U-shaped cross section and is dimensioned to tightly fit the window glass 10, so that the window glass 10 is press-fitted and fixed therein.

The support piece 12 has a substantially P-shape, and extends from the inner wall 11a of the glass guide 11 to the outer surface of the bottom wall 11b at an upper side 1.
The central bending portion 12b of 2a1 is fixed, and the lower portion 12c is suspended from the center of the glass guide bottom wall 11b.

At the lower end of the lower portion 12c, there are hook-shaped curled portions 12 that are curved upward at three locations at intervals on both front and rear sides and in the center.
d.

Note that the glass guide 11 and the support piece 12 may be formed integrally.

The movable guide rails 13 are long in the front-rear direction and have a box-shaped cross section, and two moveable guide rails 13 are spaced apart from each other in the front-rear direction on both sides in the front-rear direction, and are curved downward after protruding upward from the upper end of the vertical wall 13b. A hook-shaped curled portion 13a is provided.

The curled portions 13a are fitted between the curled portions 12d of the support piece 11, so that the curled portions 12d and 13a are combined in a staggered manner.

Curl parts 12d and 13 combined in a series in a staggered manner
The pin 14 is rotatably inserted into the curved part of the support piece 1.
2, a movable guide rail 13 is connected to the window glass 10 so as to be freely rotatable in a direction substantially perpendicular to the window glass 10.

A moving guide rail 1 rotatably connected to the support piece 12
3, similar to the conventional example shown in FIG. and are slidably engaged via pins 18 and 17.

A fan-shaped rack 19 is provided at the lower end of the first arm 15 and engages with a pinion (not shown) rotated by the handle shaft 20, and is rotatably connected to the center of the first arm 15 so that The lower end of the letter-shaped second arm 16 is slidably locked in a long hole 21a formed in the stationary guide rail 21 via a pin 22.

In the case of the above structure, when the handle shaft 20 is rotated, the fan-shaped rack 19 rotates, the first arm 15 and the second arm 16 move up and down, and the movable guide rail 13 and the support piece 1
2. The window glass 10 is raised and lowered via the glass guide 11 to open and close the window.

At this time, although the windshield 10 has a large curvature, since the movable guide rail 13 is rotatably connected to the support piece 12 fixed to the windshield 10 in a direction perpendicular to the windshield 10, window glass 10
The movable guide rail 13 follows and rotates according to the curvature of
To absorb the bending of the windshield 10.

Therefore, even if the windshield has a large curvature, it can be raised and lowered smoothly.

Further, since the structure is simple, just providing staggered curls on the support piece and the moving guide rail, it has the advantage of being easily and inexpensively put to practical use.

Claims (1)

[Claims for Utility Model Registration] The above-mentioned support piece is fixed to the glass holder that fixes the window glass, and the movable guide rail is slidably engaged with the end of the arm that is moved up and down by the rotation of the operating bundle. The support piece and the movable guide rail are provided with curled parts in a staggered manner through which pins can be inserted, and the pins are inserted into the curled parts to enable the movable guide rail to rotate relative to the support piece.
