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 fixed to a moving guide rail 2 with screws 3, 3, and the moving guide rail 2 is 4. First arm combined in an X shape. The second arm 5 is slidably supported at its upper end on the glass side, and a fan-shaped rack 6 provided at the lower end of the first arm 4 is engaged with a pinion (not shown) rotated by a handle 7. Its lower end is slidably locked to a stationary guide rail 8 fixed to a door panel (not shown), and by rotating the fan-shaped rack 6 by operating the handle 7, the window glass 1 can be raised and lowered. I am trying to open and close it.

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.

If each part is provided with play, especially the play in the width direction of the vehicle, it will be possible to raise and lower the vehicle, but the value as a product is low and it cannot be used in practice.

This idea was made in view of the above-mentioned problem, and the connecting piece that connects the window glass and the moving guide rail is made of flexible synthetic resin, and the connecting piece is made parallel to the moving guide rail. A thin hinge part is formed, and the windshield and the moving guide rail are rotatably connected in the direction perpendicular to the windshield via a connecting piece to absorb the curvature of the windshield. It is an object of the present invention to provide a window regulator for an automobile that can be smoothly raised and lowered.

Hereinafter, this invention will be explained in detail with reference to the embodiments shown in FIGS. 3 and 4.

Both front and rear lower ends of the windshield 10, which has a large curvature, are connected to the movable guide rail 12 via connecting pieces 11.11.

The movable guide rail 12 has the same shape as the conventional device shown in FIG.
The upper ends of the first arm 13 and the second arm 14 and the pin 15 are shown in b.
．． A fan-shaped rack 17 is provided at the lower end of the first arm 13, and is engaged with a pinion (not shown) rotated by an operating handle shaft 18. The lower end of the second arm 14 is slidably engaged with a stationary guide rail 19 via a pin 20, and when the operating handle is rotated, the first arm 13. The movable guide rail 12 is moved up and down via the second arm 14.

The pair of front and rear connecting pieces 11 are made of flexible synthetic resin and integrally formed into a shape as shown in FIG. 4.

That is, an engaging portion 11b that protrudes outward is provided on the upper side of the main body 11a, which has a substantially elongated parallelepiped shape, and a thin hinge portion 11c is formed by cutting an arcuate cross section from the outer surface slightly below the center portion. An insertion hole 11d is formed below the hinge portion 11C.

The engaging portion 11b is provided with a collar portion 11b2 protruding in the outer circumferential direction at the tip of the columnar portion 11b1.
b2 is formed so as to be tapered from the distal end toward the proximal end, and the cylindrical portion 11b is formed from the distal end surface of the collar portion 11b2.
There are 11 grooves cut into a V-shape towards the base end of the +.

On the other hand, through holes 1 are provided at the lower ends of both the front and rear sides of the windshield 10.
The cylindrical portion 11b1 and the collar portion 11b2 of the engaging portion 11 are normally larger in diameter than the through hole 10a, but when bent, the diameter becomes smaller than the through hole 10a. It is formed so that it can be inserted.

Further, a piece 11e projecting inward is provided above the insertion hole 11d of the connecting piece 11, and the piece 11e and the hinge portion 11c are formed in parallel.

The connecting piece 11 is first connected by inserting the engaging portion 11b into the through hole 10a of the window glass 10.

At this time, since the tip flange 11b2 has a tapered shape with a small diameter at the tip, it can be easily inserted into the through hole 10a, and is bent by the split groove 11bl+ to become a small diameter and inserted beyond the flange 11 to the cylindrical portion 11b1. do.

When the flange portion 11b2 exceeds the through hole 10a, it restores its shape and becomes larger in diameter, comes into contact with the outer surface of the windshield 10, and the main body 11
The window glass 10 is held between the

Further, the cylindrical portion 11b1 also comes into pressure contact with the circumferential surface of the through hole 10a due to the outward restoring force, so that the window glass 10
is securely connected to the connecting piece 11.

Next, the piece lie of the connecting piece 11 is connected to a movable movable member having a U-shaped cross section, f
The screw hole 12e drilled in the central vertical wall 12d of the moving guide rail 12 is brought into contact with the upper surface of the upper water wall 12c of the trail 12, and the insertion hole 11d of the connecting piece 11 is aligned, and the screw 21 is screwed into the connecting piece. do.

At this time, the movable guide rail 12 comes into contact with the piece 11e, and since the piece 11e and the hinge portion 11c are parallel, the hinge portion 11c is parallel to the movable guide rail 12.

In the case of the above configuration, when the handle is rotated and the movable guide rail 12 is raised and lowered via the first arm 13 and the second arm 14, the window glass 10 is raised and lowered via the connecting piece 11.11, and the window is opened and closed. do.

At this time, although the windshield 10 has a large curvature, the hinge portions 11c and llc of the connecting pieces 11, 11 can freely rotate in a direction perpendicular to the windshield 10, so the movable guide rail 12 can be moved around the windshield. The windshield 10 rotates following the bending of the windshield 10, absorbing the windshield bending, and allowing the windshield 10 to move up and down smoothly.
