11 Claims.

This invention aims to utilize, in car doors, windows whose forward and rear edges are parallel except as to an upper portion of the forward edge which is slanted backward for the use indicated.

There being recognized advantages in the inclination of Windshields, in the minimization of windshield frame elements or door frame elements at the ends of a windshield, and in a corresponding inclination and reduction of window frame elements provided for use adjacent the ends of Windshields, it is an object of the present invention, providing a substantially trapezodial window opening in the upper portion of a car door and employing in said opening a window whose forward edge includes an obtuse angle (a lower guide-engaging portion of said edge and a rear edge of said window being preferably substantially parallel and ordinarily vertical) to provide improved means for at all times so supporting and guiding other portions of the edges of said window as to obviate necessity for so positioning any channel as to engage the extreme upper portion of said forward window edge during completion of an opening movement of said window; and advantageous embodiments of the present invention, in which an extreme upper portion of a forward window edge may even be exposed to view during the completion of such lowering movement, may include, in addition to convergent upper channel elements respectively receiving the rearward edge of said window and the upper portion of said forward edge thereof when said window is closed, a double-arm regulating means connected with the lower edge of said window, and additional channel elements whose bottoms are respectively in constant engagement with the rearward edge of said window and with the lower portion of the forward edge thereof,the last-mentioned channel element being upwardly so expanded as to provide widening flanges having edges in substantially parallel relationship with the upper portion of said forward edge, in order adequately to support the latter when said window is lowered out of engagement with the corresponding upper channel element.

Other objects of the present invention, including preferred angular relationships and various details of construction of cooperating parts, may be best appreciated from the following description of an illustrative embodiment thereof, taken in connection with the appended claims and the accompanying drawing.

Fig. l is an elevational inside view of a doorwindow organization illustrative of the present invention, parts being broken away from all adjacent parts such as windshield frame or door frame or post elements being omitted.

Fig. 2 is a view comparable with the left-hand portion of Fig. 1, but showing the window of the illustrated door as approaching its lower limit of motion.

Fig. 3 is a detail sectional view, on an enlarged scale, taken substantially as indicated by the line 3-3 of Fig. 1.

Fig. 4 is a similar sectional view, taken substantially as indicated by the line 44 of Fig. 2.

Fig. 5 is a view taken similarly to the views thereabove, but showing an optional variation in the form of the window opening.

Referring first to the more general features shown in Figs. 1-4 inclusive, the door D comprises an outside panel l0 and an inside panel I I, extending substantially parallel with one another and secured together by a Z-section peripheral element l2, of a known type. Panels [0 and II are shown as so cut and shaped as to provide a frame for a substantially trapezoidal window opening bordered by a top edge l3, a bottom edge l4, parallel therewith, a rear edge l5, and a forward edge l6,the latter being shown as downwardly divergent from both the mentioned edge l5 and an inclined edge ll, provided by the upper portion of door Dvadjacent to a correspondingly inclined windshield frame element or post, not shown.

Movable to and from a position of closure relatively to the mentioned window opening, there is shown a window l8, generally corresponding in configuration with said opening, in that it includes a top edge I 3', a bottom edge l4, and a rear edge l5, respectively extending substantially parallel with the corresponding edges of the mentioned opening and adapted to be concealed and supported by said edges, or by channel elements adjacent thereto, when said window is closed.

A lower portion of the mentioned door beingshown as defined by substantially vertical edges l9 and 20, the forward edge of the window I8 is shown as comprising not only an upper portion I6 parallel with the mentioned edge I6, but a lower portion 20 parallel with the door edge 20 and engageable with the bottom of a special channel element 2| during manipulation of the win dow l8 by any means adapted to obviate tilting thereof. Opposite and parallel to channel 21 there is shown a cooperating guide channel 22, positioned at all times to receive a portion of the edge ii of said window; and said edge is shown as perpendicular to edges l3 and I4 thereof.

When in its closed position, the window I 8 may be supported by means including not only by an upwardly open channel element 23, movable by some suitable regulator, but also

upper channel elements

24 and 25, respectively extending par- 31 and 38, entering a lateral groove provided in the channel element 23 as to operate in a known manner. 7

In preferred embodiments of this invention, although a central portion of the lower edge 14' of the window I8 is secured in the channel ,23,

terminal portions Ma and lb of said loweredge are always retained between lateral flanges 40,

40' and 4|, M of the respective channels 2| and 22; and the channel element 2| is outwardlyextended in such manner that the edges of the flanges 40 and 4| extend substantially parallel with the forward edge I6 of the window opening and the upper portions thereof are adapted to receive a considerable portion of the correspondingly inclined upper portion I 6' of the forward edge of the window l8 whenever said window is lowered to such a position that the last-mentioned edge is downwardly withdrawn from the cooperating upper channel element 25, extending substantially parallel therewith.

The general mode of operation of all parts'of the disclosed organization having been indicated in connection with the description thereof, it is suggested in Fig. 5 that, if desired, although an obtuse angle 42 between the upper portion I6 and the lower portion 20' of a forward window edge may in most or all cases be substantially greater than an angle 42 between corresponding portions [1 and 20 of a door receiving said window, in case it is considered important completely to obviate exposure of the upper portion of a forward window edge incidentally to a raising and/or lowering of the same the forward edge of a window opening may be so modified as to include not only an inclined upper portion [61 but a substantially vertical lower portion lBb,-a corresponding angle 42" between these parts being preferably similar to an angle '42 or to the more obtuse angle between the upper portion I6 and the lower portion 20 of the forward edge of the window cooperating therewith in door D; and the

upper channels

24, 25 are preferably formed integral with one of the panels [0, H or with another part providing a frame for the window.

Although the foregoing description has included details of but one complete embodiment of the present invention, and suggestion of but one alternative form, it should be understood not only that various features of this invention might be independently used but also that numerous additional modifications might easily be devised by skilled Workers, if informed of the foregoing,-all without departure from the scope of the present invention, as the latter is indicated above and in the following claims.
