Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an improvement in a window glass lifting device for lifting and lowering a window glass of an automobile door in order to open and close it.

(Prior art) Generally, as a device for moving the window glass of an automobile door up and down, a plurality of guide rails are provided in the door panel, and the window glass is moved up and down using a glass lifting means such as an X-link type or a cable type. It was designed to do so.

For example, as seen in Utility Model Application No. 56-143372, guide rails are provided in the front and rear of the door panel in the vertical direction, and guide pieces such as rollers and sliders at the front and rear of the window glass are inserted into the guide rails to raise and lower the window glass. Structures adapted to move are known. However, in the above structure, the guide pieces provided at the front and rear of the window glass are installed at the bottom of the window glass at approximately the same height so that they fit into the guide rails even when the window glass is raised to the uppermost position. located at the location. Therefore, when the window glass is raised, there is little effect of fixing the deflection of the window glass in the door inward and outward directions, that is, in the vehicle width direction, and this deflection is likely to occur. especially,
The above-mentioned vibration in the vehicle width direction is noticeable in a door of the doorless type because there is no member for regulating the raised window glass.

It is also possible to increase the number of fixing points of the windshield by adopting a stabilizer, etc., but the difference in the vertical position of the fixing points is small and the effect of suppressing the deflection of the windshield in the width direction of the vehicle will not improve much. At the same time, the number of restraint points on the window glass increases, causing distortion when the window glass is raised and lowered, and the smooth movement of the window glass may be hindered.

On the other hand, in order to ensure positional regulation in the longitudinal direction of the vehicle body, including the direction of rotation of the windshield, the number of sliders whose position is regulated in the longitudinal direction of the vehicle body relative to the guide rail is 3 or more. If the relative position of the guide rails deviates due to the processing accuracy of the guide rails, the accuracy of assembly to the door panel, etc., problems such as prying may occur between the impulse element and the guide rails when the window glass is raised or lowered. ,
This reduces the ability to ascend and descend.

(Object of the invention) In view of the above circumstances, the present invention supports the window glass with the minimum necessary restraint points shifted vertically,
It is an object of the present invention to provide a windshield lifting device for an automobile door that effectively controls the deflection of the windshield in the vehicle width direction and allows stable holding and lifting/lowering operation.

(Structure of the Invention) The window glass lifting device of the present invention includes a first guide rail that extends substantially vertically on a decorative member provided at least at a triangular corner portion of a door panel, and a first guide rail that extends in the longitudinal direction of the vehicle body. A second guide rail and a third guide rail are sequentially installed at predetermined intervals, respectively, in a substantially vertical direction without overlapping each other, and the first guide rail and the third guide rail are installed on the window glass.
One each of a first slider, a second slider, and a third slider are attached to the second guide rail and the third guide rail in a slidable manner and supported with position control in the vehicle width direction. , when the window glass is in a substantially fully closed state, the first slider is positioned on the first guide rail of the decorative member part above the door panel body, and the second slider and third slider are placed inside the door panel body. The second slider is positioned on the second guide rail and the third guide rail respectively, and the second slider is placed on the third guide rail.
The first slider is positioned lower than the slider, and furthermore, the first slider is provided so as to be movable in the longitudinal direction of the vehicle body with respect to the first guide rail, while the second slider and the third slider are provided. This is characterized in that the second guide rail and the third guide rail are provided with their respective positions regulated in the longitudinal direction of the vehicle body.

(Effects of the Invention) According to the present invention, the first guide rail is disposed on the decorative member provided at least at the triangular corner above the end of the door panel, and the first guide rail and the second
When the first to third sliders, each of which is attached to the windshield, are held in position in the vehicle width direction by the third guide rail and the third guide rail, and the windshield is raised to a substantially fully closed state. In this case, the first slider is placed above the door panel to ensure a large difference in the vertical direction of the support points, and the intermediate second slider is placed below the third slider to increase the distance between adjacent supports. Increase the vertical difference between the points to 3
Support points can be effectively distributed, and vibrations of the windshield in the vehicle width direction can be effectively controlled.

In addition, the positions of the second and third sliders are restricted in the longitudinal direction of the vehicle body, and the first slider is not restrained in the longitudinal direction, so that the second and third slider Support in the longitudinal direction of the vehicle body including the rotational direction of the windshield can be ensured using the minimum necessary two support points of the child. Therefore, even in the case of a door of the chassisless type, it is possible to stably hold the window glass and drive it up and down.

In particular, if the first slider is configured to restrict its position in the longitudinal direction of the vehicle like the second and third sliders,
The installation space in the vehicle width direction increases, making it difficult to install it in decorative parts where the space in the vehicle width direction is narrow compared to door panels. By regulating the position only in the vehicle width direction, the first guide rail can be provided and the first slider can be slid even on a decorative member with a narrow space as described above.
