DESCRIPTION:
BRIEF SUMMARY
The invention relates to an automotive vehicle having at least two side windows, at least one of the panes being arranged in a door and wherein the door comprises a frame which receives the pane together with its rear marginal portion for longitudinal movement along a substantially vertical guide track.
In known arrangements a substantially vertical gap is present within the area of the window, between the window frame and an adjacent structural member which also supports a pane. Four door vehicles comprising a center body pillar which forms part of the exterior shell of the vehicle even have two gaps. These gaps require very precise positioning of the structural members relative to each other, and often they are the cause of noise at higher speeds. Known solutions by and large provide for wide structures thus impeding visibility in this area.
The invention is based upon the task of avoiding the formation of gaps within the window area, with simple means.
The task is accomplished by the characterizing features of claim 1.
By structuring the frame which supports the first pane in such a manner that it extends to the second pane and overlaps an outer portion thereof, the formation of open gaps is avoided. In this manner the often annoying hissing and whistling noises generated at higher speeds are prevents by eliminating their cause, rather than by attempting to improve the noise by additional means (e.g. gaskets). By covering all vertical glass edges time-consuming adjustments in tolerances become unnecessary.
The invention may advantageously be employed in the area of a window at the transition between the front door and a rear side door, at the transition between a rear side door and an adjacent rigidly mounted third side window, or in the case of two-door vehicles, at the transition between the driver's door, or passenger's door, and a fixed or movable second side window.
The invention may be employed for windows in many different frames, even though certain embodiments--as pointed out in the subclaims--are preferred. Thus it is possible to utilize conventional frames, i.e. U-shaped profiles, as well as frames arranged on the rear surface of the panes in which the panes are guided by means of slide members. Combinations of both kinds of frames are equally useful, as is the use of a frame guiding the pane at its rear edge outside of the body of the frame. Such a window guide, in which the invention may be utilized with particular advantage has been shown in U.S. Pat. No. 3,703,053.
Advantageously the frame covers an outer portion of a body pillar arranged between the windows, thus providing for an enlarged window surface as well as a good seal.
It is particularly advanateous to provide the frame at it inner surface with a covering which affects a marginal portion of the second window when the door is closed. This would provide for a guide for the second pane, in case it is recessable. More particularly, the covering would prevent lifting off of the pane at high speeds and dampens vibrations of the pane. In case the second window is fixed, such covering may essentially serve as a seal.
In vehicles comprising two doors at each side, and a body pillar between them, it is especially advantageous to guide the second pane mounted in the rear door at its rear edge only and to arrange the forward edge between gasket members at the frame between the forward door and the body pillar. The two gaskets provide for a true guide for the second pane without requiring a separate frame or a guide rail.
Claim 5 characterized an advantageous embodiment of the frame relative to the guiding of the first pane.
An embodiment of the invention has been depicted in the drawing and will hereafter be described more fully.
FIG. 1 schematically depicts a forward and a rear door of a passenger car,
FIG. 2 depicts the doors of FIG. 1 as mounted into a vehicle, and
FIG. 3 is a sectional view along line III--III of FIG. 2.
A passenger car forward door 5 as shown in FIG. 1 comprises a door body portion 7 with a substantially vertical frame
