1 Claim.
This invention relates to electrically operated window regulators.
It is the object of the invention to provide power operated window operator which will easily and noiselessly raise and lower a window, particularly a window of an automobile body. With the advent of the wide torpedo type of body it is now extremely difficult for a driver to raise and lower` the window on the right hand side. The window regulator handle is beyond his reach when he is in the ordinary posture, and in order to grasp it he has to lean way over to one side, which may interfere with his driving.
Power operated window regulators are not new, but I believe that a lever type of regulator operated in the way hereinafter described and shown in the drawings is new and is a distinct advance over other types of power operated window regulators heretofore proposed.
In the drawings Fig. 1 is an elevation of the window regulator showing the parts in several positions.
Fig. 2 is a similar view of a modied form of the invention.
Fig. 3 is a vertical section of the form shown in Fig. 1.
Fig. 4 is a cross-section showing the motor drive of the screw shaft and the slip clutch.
Fig. 5 isa cross-section on the line 5-5 of Fig. 3.
The type of cross arm regulator need not be described in detail. It comprises a pair of cross levers I and 2. The lower end 3 of lever 2 slides on a horizontal guide channel and the upper end 4 slides in a guide channel 5 secured to the bottom of the window panel. The actuating lever I has its swinging end secured in the guide channel 5 by means of roller B. This lever I is part of a bell crank lever which is pivoted at 'I in the supporting plate 3. A clock type of counterbalancing spring 9 has one end fastened to the pivot pin 1 and the other end to the bracket I Il. The power arm I I of this bell crank lever is operated by a means hereinafter described. (This type of regulator is shown, described and claimed in the Graf Patent No. 2,010,075.)
0n the lower end of the power arm II is spot welded a'channel track I3. In this track travels a pin I5 fastened to nut I4. Washers I6 and I1 of fibrous material are located on the outside and inside of the channel track. The metal washer I8 is provided on the end of the pin I'I which is riveted over to hold the assembly in place. Screw I9 is supported on the fixed arm 20 which is secured by screws to the transmission case 2 I. As the screw is revolved, the nut travels along the screw and can pivot in the opening of the channel track and can also slide up and down in the channel track.
A motor M has an armature shaft 22 which is keyed to the pinion 23 which in turn drives the large gear 24. This gear is free to rotate on bushing 25 which is keyed to the screw shaft I9. Screw shaft I9 is supported in the transmission case 2| by the roller bearings 26 and also at its end by bushing 21. Splined to the bushing 251s a driving disc 28 of a multiple disc clutch 29. Discs 33 are spiined at 34 to the hub of the gear 24. Discs 35 are splined to the driving disc 28. Spring 30 puts the discs under sufficient pressure to raise and lower the window panel, but when the panel reaches the limit of its movement, these discs can slip. This provides a slip clutch drive.
In the form of the invention shown in Fig. 2, the lower end of the power arm of the bell crank lever is pivoted at 3l to the nut I4 which travels on screw I9. Here the screw supporting arm 20 together with the motor and the transmission M is fulcrumed at 32 on the supporting bracket 33. This accommodates the driving mechanism to the swing of the actuating lever.
What I claim is:
In a power operated window regulator, the
combination of a window lifting mechanism havv ing a lifting arm, a track on the power arm of the lifting mechanism, said track being a channel with turned-in flanges, a nut having a pin slidable and rotatable in said track, fibre washers surrounding said pin and engaging opposite sides of said flanges, a screw shaft flxedly supported for causing said nut to travel therealong and power operated means for rotating said screw shaft.
