10 Claims.

This invention relates to window regulator mechanism particularly adapted for use in vehicle bodies or the like for raising and lowering the windows thereof. Although susceptible of various uses and adaptations the invention is the vehicle into and out of position to provide a Ventilating slot or opening at the forward upright edge of the glass.

An object of the invention is to provide a regulator mechanism of the type having oppositely swinging arms wherein means is provided for developing a diiferential frictional resistance between the arms and window whereby the window will be urged or moved longitudinally during the vertical travel thereof.

A further object of the invention is to provide a regulator mechanism for moving the window .glass horizontally or longitudinally in its plane vfrom fully closed position into position whereby a Ventilating slot is produced at the forward edge of the glass and thence in a downward vertical direction, and wherein meansV such Vas springs of dierent characteristics are provided between the arms of the regulator and the window glass rail eiective to produce sufficient differential friction to change the path of movement of the glass ,min the accompanying drawing, in which:

Figure 1 is a side elevation of a portion of an automobile door viewed from the inside with the upholstery removed and showing the window in its closed position, dot and dash line showing the window moved rearwardly to provide a ventilating opening;

Figure 2 is an enlarged edge view of the upper end of the forward regulator arm showing the rail-engaging stud and spring pressedV washer;

and

Figure 3 .is a view similar Yto Figure 2 showing the rear regulator arm, stud and spring pressed washer. V- f 1;.The. illustrated embodiment ofthe invention has the usual window opening II and windowlZ guided in its vertical movements by front and rear runways I3 and I4 respectively. The runway I3 is relatively narrow, vwhereas runway I4 is relatively deep and extends from its upper end downwardly to a point below the window opening II where it inclines downwardly and forwardly, as indicated at I5. By providing the inclined portion I5 of the runway, ample clearance is afforded for the operating spindle IB of the door latch (not shown), a handle Il being Vdisposed on the outside of the door and operatively connected to the outer end of the spindle I6 for actuation thereof. The lower portion of the runway I3 is made deeper, as indicated at I8, and inclines downwardly and forwardly similar to the runway portion I5. Y

Embracing the lower edge of the window I2 is a channel stripl I9 of U-shape, and between the strip I9 and thewindow is disposed suitable packing. Fixed to one side of the channel strip I9 are rails, 23, which are slotted to receive pins 2I and 22 carried by the outer ends of regulator arms 23 and 24 respectively. Secured to the lower end of the regulator arm 23 is a gear sector 25 meshing with a similar gear sector 2,6. Integral with the gear sector 26 and concentric therewith is alarger sector 21 with which a pinion 28 meshes. The pinion is operated by a suitable handle (not'shown) disposed on the inside of the door, and these parts are carried by a mounting plate 29, on which pivot pins 30 and 3| for the sectors 25 and 26 respectively, are carried. A counterbalance spiral spring arrangement 33 is provided for the gear sectors, as will be readily understood by those skilled in this art, a suitable clutch 34 associated with the pinion being also provided to retain the parts in Vadjusted position. Fixed to the upper end of the regulator arm 23 is a plate 35 having a downwardly inclined finger-like extension 36, which isprovided with an upwardly and rearwardly curved surface 31, terminating in a notch 38. Secured-to the rail Y20 and Vprojecting outwardly therefrom is a pin 38a engageable by the notch 38. The plate 35 inclines downwardly and rearwardly from the notch 38 to the arm 23, as indicated at 39., 1 As shown in Figure 2,.w ashers 40 are mounted on the studsV 2I and 2,2 between the headed end ythereof and the respective regulator arms.V Mounted on the stud 2I and arranged -to bear against the washer is a coil springV 4I, the Vinner end bearing against the plate 35. A coil' spring 4Ia on the stud 22 bears against the respective washer 40 for urging the latter outwardly. It will be understood that the washers i4!) bear against-A 55 Vl follows?v y Assuming that the window is in its raised position with the Ventilating slot closed, the operata may be four times stronger than the spring AI..

The advantage of this arrangement will hereinafter appear.

The Voperation of the above mechanism-iis as ing handle is moved to actuate the'jpinionZa;

which, through the gearing above described, s

Thenotched lator arm 23 to the right, the window I.2.is caused to move to the right or rearwardly of the vehicle softhat thegffrontvertical cdg'eof the windowfis (moved out of the channel I3'and therear'vertical 4edge is movedintothe relatively'deep channel "H, as indicated by the ,doti and 'dash lines A.

It will be apparent that the characteristic feature of the invention resides in the provision of differential friction developed between'the outer ends of the regulator arms and the rail, which, in this instance, operates to cause the window to Vtravel-.in an., inclined path duringits vertical in a straight verticalpath, particularly for the lpu'rposefof avoidingfjamming or cramping of the window during. the "raising and lowering moveportion 38 of the plate 35 is in engagement withr the pin 38a so that upon movement. of rtheire'gu-.L
