JPH0660547B2 - Safety device for automobile window regulator - Google Patents

Description

TECHNICAL FIELD The present invention relates to a safety device for an automobile window regulator, and more particularly to a safety device for an automobile window regulator that is suitable for use in a sliding door of a one-box car or the like.

[Conventional technology]

Conventionally, as a safety device for such a window regulator for an automobile, one described in Japanese Utility Model Laid-Open No. 62-96476 is known.

This is composed of a bottom dead center position switching means for switching the bottom dead center position when the door glass is opened to a plurality of upper and lower stages by a stopper which releasably abuts on the carriage of the door glass. The operating means for switching operation is composed of a manual lever and a link or wire connecting the manual lever and the stopper.

[Problems to be Solved by the Invention]

However, in such a conventional device, the stopper operated by the manual lever prevents the downward movement of the window glass on the way, so that the stopper will be damaged if an adult forcibly applies a load, and the stopper will be reused. There was a fear of becoming impossible.

Further, if an attempt is made to improve the safety by providing a manual lever at the end of the door or the like so that an infant or the like cannot operate it, there is a disadvantage that even if an adult wants to fully open the window glass, it cannot be fully opened. .

An object of the present invention is to solve such a conventional problem and prevent a window glass from being fully opened by a descending operation with a weak force by an infant or the like, and a safety device for an automobile window regulator which is not damaged even if an excessive load is applied. To provide.

[Means for Solving the Problems]

In order to achieve the above object, the present invention relates to a window regulator for an automobile that vertically moves a window glass arranged in a window portion of a door, in accordance with a switching operation of operating means, a window outside a carrier plate movement locus of the window regulator. It can be switched between an unlock position and a lock position where it abuts the carrier plate in the movement locus, and can be moved to an operating position that allows the carrier plate to move downward when a pressing force greater than a predetermined value is applied by the carrier plate at the lock position. It is characterized in that a stopper mechanism is provided.

[Action]

According to the present invention, the stopper mechanism is switched between the unlock position outside the carrier plate movement locus of the window regulator and the lock position where it abuts against the carrier plate within the movement locus according to the switching operation of the operating means. Therefore, when the window glass is lowered while in the locked position,
The carrier plate comes into contact with the stopper mechanism, and further lowering is restricted, which functions as a safety device.

However, when in this lock position and a pressing force of a predetermined amount or more is applied, the stopper mechanism moves to the operating position that allows the downward movement, and the carrier plate and thus the window glass can be lowered.

Therefore, even if an excessive force is applied, the stopper mechanism will not be damaged.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2 show an embodiment of the present invention.

FIG. 1 shows a one-box type vehicle to which the present invention is applied, 1 is a sliding door, 2 is a window, 3 is a window glass, 4 is a carrier plate fixed to the lower end of the window glass 3, and 5 is a It is a geared cable that drives the carrier plate 4.

The geared cable 5 is slidable in a guide tube 6 fixed to the door 1 as shown in FIG. 2, and meshes with a gear rotated by a window regulator handle (not shown) as is well known.

Further, the guide tube 6 has a slit 6A in its axial direction.
And the leg portion 4A of the carrier plate 4 is projected.

Reference numeral 7 is a base plate fixed to the door 1 together with the guide tube 6, and has a partial cutout 7A on the outer circumference.
Reference numeral 8 denotes an actuating lever pivotally supported by a shaft 9 planted in the base plate 7 so as to be rotatable. It is bent and formed. The claw 8C engages with the notch 7A of the base plate 7 described above, and the swing range of the operating lever 8 is limited.

A stopper lever 10 is also rotatably supported on the shaft 9 and has first and second arm portions 10A and 10B which are separated substantially at right angles.

Reference numeral 11 denotes a spring, which urges both levers in a direction in which the second arm portion 10B of the stopper lever 10 comes into contact with the claw 8B of the actuating lever 8, that is, counterclockwise in the drawing.

A stopper mechanism 15 is configured by the base plate 7, the operating lever 8, the shaft 9, the stopper lever 10 and the spring 11 described above.

Further, the means for operating the stopper mechanism will be described with reference to FIG.

Although shown in one drawing for convenience of explanation, what is shown on the left side in the figure is an example when it is attached to the vertical wall surface of the door 1, and what is shown on the right side is an example when it is attached to the indoor side surface of the door 1. It goes without saying that either of them may be selected according to the size of the vehicle or the like. Since both are functionally the same, they will be described using the same reference numerals.

That is, 20 is a mounting bracket, which is fixed to the door 1. Reference numeral 21 is an operation lever, which can be rotated around a pin 22 implanted in the mounting bracket 20. Reference numeral 23 denotes a connecting link, one end of which is engaged with a hole 21A formed in the operating lever 21, and the other end of which is engaged with the engaging hole 8A of the operating lever 8 described above.

Next, the operation of this embodiment will be described with reference to FIGS. 3 and 4.

When the operating lever 21 is rotated in the direction of arrow A shown in FIG. 2, the operating lever 8 is rotated around the shaft 9 together with the stopper lever 10 via the connecting link 23 to be in the lock position shown by the solid line in FIG. At this time, the claw 8C of the operating lever 8 contacts the side wall of the notch 7A of the base plate 7 and the stopper lever 8C.
The first arm portion 10A of 10 is the slit 6A of the guide tube 6.
It is located above, that is, within the movement trajectory of the carrier plate 4.

In this state, the window regulator handle (not shown) is rotated, and when the geared cable 5 is moved to lower the carrier plate 4, the leg portion 4A of the carrier plate 4 is moved.
Comes into contact with the first arm portion 10A, and further downward movement is prevented by the biasing force of the spring 11. Therefore, if the set load of the spring 11 is set in consideration of the force of an infant or the like, the window glass 3 stops at the half-opened position and safety is secured.

When a stronger force is applied by an adult or the like in this state, the stopper lever 10 rotates against the urging force of the spring 11, and the first arm portion 10A moves to the operating position shown in FIG. The downward movement of the carrier plate 4 is allowed.

When the operating lever 21 is rotated in the direction of arrow B in the second illustration, the operating lever 8 is unlocked together with the stopper lever 10 at the position shown by the chain double-dashed line in FIG. After moving to the position, the carrier plate 4 can be moved downward without any constraint.

〔The invention's effect〕

As is clear from the above description, according to the present invention, the window glass cannot be fully opened by a descending operation with a weak force such as an infant, so that safety is ensured and, even when the window is locked, if the operating force is strong, the window can be fully opened. Since it is possible, it is possible to obtain an automobile window regulator that is easy to use and is not likely to be damaged.
