4 Claims.
This invention relates to power operated window regulators. It is desirable to use power operated window regulators without providing the usual handle for hand operation. The window regulator handle on the inside of a car is undesirable, as it is in the way of the kneesand the get out.
To overcome this dimculty, I hai'e'provided an emergency release for the clutchwhich I believe to be a new and novel idea. I have also provided an effective clutch-which is self-locking and self releasing when the power is eflective.
In the drawings:
Fig. 1 is an elevation partly in section of one form oithe invention.
Fig. 2 is an elevation of a second iorm of the invention. v
3 is a section taken on the line 3-3 of The window regulator is a lever type of regulator that here happens to be shown with a lifting arm I and an auxiliary lifting arm 2. The power may be of any type but here is shown as either vacuum or positive fluid pressure. A piston 3 has a piston rod 4 connecting with the power arm 5 or the window regulator. 8 is a cylinder at the opposite ends of which are fluid connections I and 8 controlled by a. valve 9. The
source of power is here shownas a manifold ill of an automobile engine.-
The clutch is attached to the load arm 01' the regulator and is a roller clutch with a roller llstressed by the free end of the clock spring l2. Such' a clutch is described and claimed in the Simpson Patent No. 1,343,410. The roller swings about a. circumference or periphery of a disc l3 which circumference has its center at the center I -I, that is, when the window tries to drop, the
wedging surface I 4 lambs the roller (or it might be a ball) into the periphery of the fixed disc i3 when the window tries to jump or rise, it is free and locks the window from downward movement. I
to do this but it seldom will do any jumpingand. if itdoes, it will not, be harmful.
When efiort comes through. the power arm 5, the power arm will contact with the load arm I by means of lug IS on the power/arm. This will raise the window panel. When efiort comes to lower the window from the power arm 5, the lug IS on the power arm has a projection I! which first contacts the roller ll and drives the roller out of the wedglng engagement with lug l4 and the periphery of disc [3. Disc l3 can rotate .when releasedgby the emergency lever i8 which is best shown in the modified form of Fig. 3. It i's'pivoted at l9 and has at one end a push button 20 that protrudes through the door panel (as shown in Fig. 3). The other end has a turned down proiection 2i which, in the form shown in Fig. 1, engages in a slot in the plate 22 spot welded to the regulator plate and also slot 30 in the disc. This plate 22 also forms an anchor for one. end of the'usual counterbalancingspring 23 which is the clock type that is ordinarily used,
as shown in Fig. 2.
Ordinarily, the lever is held in locking position by spring 24 (Fig. 3) which causes the clutch to function in its normal way. Disc I3 is then a fixed member. In case or an accident, or in case the power fails and one desires to get the window down, all that is necessary is to release the emergency .lever by pushing on the button 20. The clutch ceases to be a clutch and the window will descend of its own weight or may be pulled down by pressing the hands against it and aiding gravity to cause its. descent.
The clutch plate (of Fig. 1) 25, which carries also the clutch wedging block i4, extends toward the center or the disc I3 and houses another roller 26. This roller moves in the segmental slot 21 so that, when the jambing action does take place on the surfaces of the disc, it is between the two rollers.
Clock spring 28 with its free arm forms a spring motor connection between the fixed disc l3 and the load arm I of the lifter. In case the emergency lever has been operated and the fixed disc I; has been released and the window opened, then, if the window is raised either with the power or by pulling by hand, the fixed disc will rotate back to a position where the lever can lever is parallel with the horizontal dimension .of the supporting plate, in place of .at right angles thereto (as shown in Fig. 1).
It is not (essential that the clutch be a roller or a ball clutch. It might be several of the other forms of clutches; such as a toothed clutch, or, conceivably, it might be a coil spring clutch. The main idea here involved is arranging the normally fixed member in such a way that it may, in an emergency, be released from its fixed position and allowed to rotate and thereby the clutch is temporarily eliminated as an operating mechanism.
What I claim' is:
i. In a window regulator and particularly-a power operated window regulator, lifting mechanism and a clutch therefor, including a fixed member with whichthe clutch mechanism ordinarily locks, said fixed member arranged to rotate when released, means for holding the same, comprising a member having a locking relation therewith and a spring motor connection between the fixed member and the window regulator for rotating the fixed member back to' its locking positionwhen the regulator mechanism is again operated and the clutch released.
2. In a window regulator and particularly a power operated window regulator, lifting mechanism and a clutch therefor, including a xed member with which ,the clutch mechanism ordinarily locks, said ffx'ed member arranged to rotate when released, means for holding the same,
comprising a member having a locking relation therewith and a spring motor connection between the fixed member andthe window regulator for rotating the fixedmember back to its locking position when the regulator mechanism is again operated and the clutch released, said spring motor member comprising a spring anchored to the fixed member and contacting one of-the movable'members of the regulator mech-- anism.
3. In a window regulator and particularly a power operated window regulator, lifting mechanism and a roller clutch therefor, having in combination a window regulator load arm, -a
on thesame pivot axis, the said two arms capable of a limited relative movement, a normally fixed disc which can be rotated on the same pivotal axis as the other two, a wedging block carried by the load arm and having a wedge surface adjacent the periphery of the disc, a rolling member engaging between the periphery of the disc and the wedging surface and serving to lock the two together when the load arm tries to descend, means on the power arm of the regulator for picking up the load arm after a limited movement to release the rolling member from its jamming engagement with the periphcry of the disc and the surface of the wedging block and means releasable from the inside of the car for holding the normally fixed disc from rotation.
4. In a window regulator and particularly a power operated window regulator, lifting mechanism and a roller clutch therefor, having in combination a window regulator load arm, a window regulator power arm pivotally supported on the same pivot axis, the said two arms capable of a limited relative movement, a normally fixed disc which can be rotated on the same pivotal axis as the other two, a wedging block carried by the load arm and having a wedge surface adjacent the periphery of the disc, a rolling member engaging between the periphery of the disc and the wedging surface and serving to lock the two together when the load arm tries to descend, meanson the power arm of the regulator for picking up the load arm after a limited movement to releasethe rolling member from its jamming engagement with the periphery of the disc and the surface of the wedging block and releasable means for holding'the normally fixed disc from rotation, comprising a spring-pressed lever releasable from the inside of the car and normally having one-portion looking with the normallyfixed disc.
