Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for an automobile door window glass.

In the window glass of a sashless door of an automobile, a roller provided at the bottom of the window is fitted into a sash provided inside the door, and as the roller rolls within the sash, the window glass moves up and down. is normal.

However, in order to reduce the operating force required to open and close the window glass up and down and ensure smooth operation, it is necessary to maintain an appropriate clearance between the roller and the sash, and this clearance makes it unstable to support the window glass in the half-open state. This causes the problem that the window glass vibrates while driving.

The present invention is aimed at dealing with the above-mentioned problems, and will be described below with reference to embodiments shown in the accompanying drawings.

In Figures 1 to 3, 1 is a sashless door, 2 is a window glass, and the window glass 2 is attached to the lower part of the window glass to channel-shaped sashes 3, 3 provided in the front and rear parts of the door 1. roller 4,
4 is fitted, it is guided by the sashes 3, 3 and can move up and down.

Incidentally, the vertical movement of the window glass 2 is performed by the operation of a window regulator (not shown).

As shown in FIGS. 2 and 3, the sash 3 includes vehicle body width direction guide surfaces 3a, 3b and vehicle body longitudinal direction guide surfaces 3.
Normally, it is formed in a channel shape with c and 3d, but in the present invention, as shown in the figure, a convex portion 3a' that protrudes inward of the sash is continuous in the vertical direction on one of the guide surfaces 3a in the width direction of the vehicle body. The roller 4 is formed so that the tip of the convex portion 3a' is fitted into the sash 3.
The structure is such that it comes into contact with the

The height (amount of protrusion) of the protrusion 3a' is approximately equal to or slightly larger than the clearance between the roller 4 and the sash 3 in the vehicle width direction, so that the tip of the protrusion 3a' and the roller 4 are It is desirable that the tip of the convex portion 3a has an acute-angled cross-section or an arc-shaped cross-section as shown in the figure so as to achieve a line contact or a contact state close to the line contact.

Further, as shown in FIG. 3, the convex portion 3a' is formed so as to disappear within a predetermined range below the upper part of the sash 3, and the vanishing point of the convex portion 3a' is located at the window glass 2.
The position of the roller 4 is set to approximately match the position of the roller 4 when the roller 4 rises to a height where it starts to come into contact with the weather strip provided on the window frame of the vehicle body.

The convex portion 3a' may be formed in one line as in the illustrated embodiment, or may be formed in a plurality of lines in parallel.

According to the present invention constructed as described above, the protrusion 3a' provided on the sash 3 completely eliminates the looseness of the roller 4 in the vehicle width direction, and not only can the shaking of the window glass in the half-opened state be prevented. ,
Since the contact between the convex portion 3a' and the roller 4 is a line contact or a near-line contact, the operating force is slightly heavier than the conventional type b as shown in Fig. 4, but the operating force is still small. The value is much lower than the limit value L, and from the point X when the front and rear edges of the window glass start sliding into contact with the weather strip on the window frame on the vehicle body side, the convex portion 3a' disappears, so the upper edge of the window glass comes into contact with the weather strip. The operating force required from time point Y until the upper edge pushes up the weather strip to bring it into the fully closed state is exactly the same as in the prior art, and there is no risk of any problem in terms of operating force.

As described above, according to the present invention, with an extremely simple structure, it is possible to accurately prevent the door glass from swinging without increasing the operating force, and it can bring about great practical effects.
