In installations of the present tvpei'thedoor "construction issiich that co'nventionalregulator mechanism can not 'be employed. 'As indicated in Figiire 3 "the dom nates 9 and! o areeurved, so that the major portion of each lie's er itirely outside of the plane of movement of the window panel. It will be noted also that the plane of motion of the sector gear 26 and arm 2| lies parallel to the direction of movement of the window. Thus it is necessary to provide suitable operating mechanism including an operating crank, indicated in broken lines at 30 (Figures 2 and 3), operable in a plane of rotation which is substantially parallel with the inner door panel.

In order to accomplish this a drive shaft 3| is supported in a conventional friction clutch device 32 secured to the mounting plate 25 in a position permitting a drive pinion 33 carried by the shaft 3| to engage gear teeth Ed on the sector member 26. It should be noted that the drive pinion 33 is in an intermediate position of an imaginary quadrant, the lower line of which is horizontal and passes through the axis of the stud 21. This upper position of the drive pinion is important so that the operating handle on the inside of the door is in a position convenient to the operator.

Referring to Figures 3 and 4, the broken line A indicates a horizontal base plane passing through the normal center of the drive pinion 63 and lies at a right angle to the plane of rotation. of the gear 26 (Figure 2). The line B indicates the angle of inclination of the shaft 3! along the vertical line C of Figure 4 to place the shaft substantially normal or at right angles to the surface of inner door panel. This positioning of the shaft and pinion 33 requires the rim portion 26 of the gear sector 26 hearing the teeth to be dished or inclined normal to the line B to facilitate engagement of the gear teeth and pinion.

Since the vertical plane indicated by line C is not in alignment with a line 35 (Figure 4) passing through the respective centers of the sector 25 and pinion 33, the teeth of the pinion are formed helically to accommodate their angular relation. This assures positive driving engagement between the pinion and sector gear.

Figures -5 to 8 show diagrammatically the relative positions of the operating parts of the regulator mechanism and the relation of the handle shaft 35 and handle crank 36 to the inside door panel. In Figure 5, it will be observed that the operating shaft 3! inclines straight upwardly and that the teeth of the pinion 33 properly mesh with the teeth of the dished rim 26' of the sector 26. In Figure 6, it will be noted that the handle crank 36 can be freely rocked without interfering with the inside door panel 9 and the shaft 35 inclines upwardly from the helical pinion 33. ihe proper meshing between the pinion and gear sector teeth is shown in Figure 8. Figure 7 shows the freedom afforded the handle crank 3% to rotate on the inside of the panel 9.

By way of contrast, reference is made to Figures 9 to 12 which show the same parts as cle-= scribed above and in corresponding positions, the only difference being that the gear sector is flat throughout and is not provided with the dished rim portion. The same reference numbers are used but with the exponent a. lhe differences are apparent. The teeth of the pinion 33a do not mesh properly with the teeth of the The above graphically shows advantages gained by dishing the sector rim and using the helically toothed pinion, particularly in the illustrated location of the pinion. In fact, where the pinion is raised above a horizontal line passing through the operating sector axis, it is necessary that both dishing of the sector rim and the use of the helical pinion be employed.

This application constitutes a continuation of my application Serial No. 587,761, filed April 11, 1945, and entitled Window Regulator Drive Mechanism, now abandoned.

While I have shown and described one embodiment of the invention which is the best form known to me at this time, it is to be understood that numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention especially as defined in the appended claim.

What I claim is:

In a vehicle having a window well, a window movable in and cut of said well to and from a closed position, an inside panel at the inner side of the well disposed out of parallelism to the plane of window travel, regulator mechanism for operating said window, said regulator mechanism comprising a window engaging arm, a pivotal mounting for one end of said arm disposed at substantially right angles to the plane of window travel, a gear sector for actuating said arm having a body portion substantially parallel to the plane of Window travel, a pivotal mounting for said gear sector, the teeth of said sector being inclined laterally relative to said sector body portion and out of parallel relation to the plane of window travel, a driving pinion for said gear sector, said pinion being disposed intermediate the ends of a quadrant, having a lower end which is horizontal and passing through the axis of said pivotal mounting, and having an upper end which is vertical and passing through the axis of said pivotal mounting helical teeth on said driving pinion meshing with the sector teeth, those teeth of the pinion in engagement with the teeth of the sector being normal thereto, a shaft coaxial with said pinion disposed at substantially right angles to and projecting through the inside panel, said shaft inclining upwardly from said driving pinion, and a crank handle on said shaft on the inner side of the inside panel and rotatable in a plane parallel to the inside panel.
