WINDOW REGULATOR MECHANISM June 13, 1944.
Filed Oct. 20, 1942 I John B. pavdmd INVENTOR ATTORNEY Patented June 13, 1944 UNITED STATES PATENT OFFICE WINDOW REGULATOR MECHANISM 7 John B. Parsons, Toledo, Ohio Application October 20, 1942, Serial No. 462,676
5 Claims.
This invention relates to regulators for vehicle windows particularly windows of automobiles and an object is to produce a new and improved vehicle window regulator of the swinging arm type having a cam feature by which increased force is imparted to the swinging arm in the region of the closed and fully opened positions of the window at which time a greater force is desirable in view of the increased frictional resistance to the movement of the window at those points.
Another object is to produce a vehicle window regulator of the abovecharacter which is constructed and arranged to be operated eificiently by a piston rod forming a part of a piston cylinder assembly.
Other objects and advantages will hereinafter appear and for purposes of illustration but not of limitation, an embodiment is shown on the accompanying drawing in which Figure 1 is a fragmentary side elevation of a vehicle window regulator;
Figure 2 is a fragmentary edge view of a portion of the mechanism shown in Figure 1; and
Figure 3 is a side elevation of the regulator mechanism viewed from the side opposite to that shown in Figure 1.
The illustrated embodiment of the invention comprises a vehicle window glass II], in this instance the rear quarter window glass for an automobile, the same being mounted in a channel H which embracingly engages the lower edge portion of the panel. A bracket I 2 on one end of the channel H is pivotally mounted at Is to enable the window glass Hi to rock about the pivot I3 to and from closed position. In Figure 1, the window is shown in its raised or closed position and it will be understood that by rocking the same in a counterclockwise direction, the window glass l swings into its well in the vehicle body, thereb moving the same to its open position. Fixed to the under side of the channel II is a depending retainer from which projects a stud l5 slidable in a longitudinally elongate slot IS in a swinging arm l1. of the regulator mechanism.
The inner end of the swinging regulator arm I! is pivotally mounted on a stud l8 which is carried by a mounting plate IS. The arm I! is provided with an extension 20 which forms with the arm I! an acute angle and disposed longitudinally of the extension 20 is an elongate slot 2| which receives the stud i8. The extension 20 is relatively short as compared to the arm I! and is provided with a pin 22 in its outer end portion which fits an arcuate vertically disposed slot 23 in the mounting plate l9. It will be observed in Figure 1 that the slot 23 is arranged in advance of the pivot stud I8 and is eccentric with respect thereto. In other words, the curvature of the slot 23 is not co-axial with the stud [8 but as will be observed is a relatively flat arc. This requires the inner end of the arm IT to shift along the slot 2| during the swinging movement of the arm.
As above mentioned, the pin 22 which fairly closely fits the sides of the arcuate slot 23, projects therethrough and pivoted to the pin 22 on the opposite side of the mounting plate [9 is a piston rod 24 which is vertically disposed and has a piston on its lower end which is reciprocable with a cylinder 26. Fluid such as oil under pressure may be introduced in any suitable manner to the cylinder 26 below the piston 25 through a connection 21 for forcing the piston upwardly. thereby to swing the regulator arm I! upwardly and move the window In to its closed position.
The arcuate slot 23 is so designed that the pin 22 cooperates therewith to effect a camming ac' tion for imparting increased force to the arm adjacent its upper extreme position. This is advantageous because of the resistance imposed upon the window during its final closing movement and when the window is forced into its channel which receives the free edge portion of the window. It will be apparent that not only is the force of the piston rod 24 brought into play during such closing movement, but also the camming action is imposed by'the edges of the Mom ate slot 23 on the pin 22-. It will also be apparent that since the arcuate slot 23 is in the form of a relatively flat arc, the intermediate movement of the pin is relatively free, the efiective camming action being brought into play adjacent the upper and lower end portions of the slot. A camming action similar to that above described is brought into play when the window glass Iii approaches its fully lowered or opened position at which time increased resistance is imposed on the glass by the window molding into which the upper edge of the glass fits snugly, as will be readily understood by those skilled in this art. The curvature of the slot 23 is so chosen with relation to the movement of the piston 24 as to afford a desired camming action adjacent the lower end of the window travel.
As shown, the cylinder 26 has a depending leg 28 which is pivoted to an intermediate portion of an arm 29. The arm 29 is pivoted at 30 to a bracket 3| and the outer end of the arm projects through a notch 32 in a flange 33 on the bracket 31 to afford limited swinging movement the pin 22 and is disposed between the piston rod 24 and the mounting plate Hi.
It will be manifest that as the swinging regulator arm I! swings upwardly or in a clockwise direction (Figure 1) under the action of the piston 25, the coil spring 34 is stretched or placed under tension. To effect lowering movement or movement of the glass panel I to open position,
the pressure fluid from the cylinder 26 is released, a
thereby enabling the coil spring 34 to rock the arm I! in a counterclockwise direction and thus move the window glass II) to its-open position.
In the event that the window glass H1 is moved I to its closed position, and the pressure fluid expands due to temperature conditions, the cylinder 26, due to its mounting on the arm 29, enables the arm 29 to rock to compensate for such fluid expansion.
With very slight change, the above described regulator can be manually operated by replacing the piston rod 24. with a rack bar, the actuating pinion forwhich may be manually operated. It will be manifest, therefore, that the regulator mechanism will function as above described except that a manually operated arm would be substituted for the piston rod 24.
.=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 claims.
What I claim is:
1. A regulator for a vehicle window comprising a swinging arm adapted to be operatively connected to the window, a pivotal mounting for theinner end of the arm, an arcuate cam guide in 1 advance of and eccentric to said pivotal mounting, a member in fixed relation to and movable with said arm and engaging said cam guide during swinging movements of the arm, and means to apply actuating force to said member, said last means including a piston pivoted tov said member for moving the arm in one direction and a spring for moving the arm in the opposite direction.
2, A regulator for a vehicle window comprising a swinging arm connected at one end portion to thewindow, means providing a pivotal mounting for the opposite end of said arm, an arcuate cam guide in advance of and eccentric to said pivotal mounting, an extension on said arm, a member on said extension engaging said guide during swinging movements. of said arm, said guide cooperating with said member to impart increased force to said arm during extreme portions of arm movement, and means connected to said member for actuating said arm.
