Patented Mar. 28, 1944 UNITED STAT HANDLE ASSEMBLY Emory Glenn Simpson, Detroit, Mich., assignor to Ternstedt Manufacturing Company, Detroit, Michs a corporation of Michigan- Application March 1s, 1942, Serial its- 34,930

-4' 'Claims. (01. 28753) This invention .relatesto a. handle assembly and more particularly to a handle assembly for an automobile window regulator.

It is the object of this invention to produce a handle assembly which is of simple construction, cheap tomanufacture and easily assembled.

In particular, it is the object of the invention to produce a handle assembly wherein the handle can be easily assembled to, and disengaged from, the remaining members of the assembly.

In the drawing: I Fig. 1 is asectional view through the handle assembly anda portion of the vehicle body upon which it is mounted. f

Fig. 2 is a section along the line 2- 2 of Fig.1.

Fig. 3 is a detail section of the driving spindle of the window regulator clutch taken along the line 3-3 of Fig. 4.

Fig. 4 is an end elevation of the drivingmember of the clutch.

Figs. 5 and 6 are details of the retainer or seat for the dog.

Fig. '7 is a fragmentary detail sectional view of the handle.

Fig. 8 is a fragmentary sectional View corresponding to Fig. 1 but showing a modified form of the handle assembly.

Referring more particularly to the drawing, there is shown an inner metal vehicle body panel I which is covered by trim material 2. The regulator support plate is designated 3 and the clutch housing, which is welded or otherwise secured thereto, is designated 4. A coil spring 5 is positioned over the clutch housing and reacts between the housing and the trim 2 to maintain the trim 2 and escutcheon 6 outwardly against the handle I. The handle I is provided with a hub 8 provided with an external screw thread 9.

The driving spindle of the clutch is designated l0 and is internally threaded as at H so that the hub 8 of the handle I can be screwed into the driving member ID. The driving member ID is joumaled in housing 4 which provides a bearing for the driving member ID as at l2. The driven member of the clutch is designated [3. The clutch pinion I4 is fixed on the driven member I3. The pinion I4 is journaled on the support bracket 3 as at l5. The driving member ID of the regulator is a die-casting and has cast therein a steel pintle l6 which is journaled in the pinion l4 to provide an additional bearing for the driving member of the clutch.

Although the handle I has a screw fit in the driving member I l it is essential that the handle be locked to the driving member so that it will not turn out. To this end the hub is provided with a diametrically extending recess I! in which is pivotally mounted the dog I8. The dog It is provided with a heel l9 which is pivoted in the socket 20 0f retainer 2|. A U-spring22 is positioned between the dog and the bottom wall 23 0f the recess I1. This spring at all times pivots the dog outwardly into interengagement with one of the axially extending slots 24 in driving member Ill. The handle is also provided with an opening 25 in which is positioned the plunger 26 having a tapered end 21 which engages thedog l8asat28. I To assemble the handle I in the driving mem-. ber II], the plunger 26', dog l8, spring 22 and retainer 2| are first mounted in the handle l. Retainer plate 2| is pressed into the recess ll so that it will retain the dog I8, spring 22 and plunger 26 in the handle. While plunger 26 is pushed inwardly of the handle to hold dog l8 in retracted position, the hub 8 is then screwed into the driving member 10. After the handle has been screwed into the driving member to a suificient distance so that the escutcheon 6 has a nice fit with the trimming 2, the plunger 26 is released to permit the dog to interengage recess 24. There are six recesses in driving member It) so that handle I has a wide range of rotational adjustment relative to member I0. Recesses 24 act as keepers, any one of which can be interengaged with the dog l8 to lock the handle on member H).

To remove the handle 1 from member ID it is only necessary to push in on plunger 26 which releases dog [8 from keeper 24 and permits the handle to be screwed out of member In.

In the modified form shown in Fig. 8, instead of a retainer plate 2!, the retainer 30 is formed as an integral part of the die-cast handle I. To assemble this form of the handle the spring 22 is first inserted through the mouth 3| of recess l1 and dog I8 is inserted into the recess I! so that the heel l9 pivots on socket 32. The handle 1 is provided with a hole 33, the outer end of which is closed by escutcheon 6 when the handle is in final assembled position on member II].

To assemble the handle on the driving member ID, a pin or wire, or a. similar instrument is passed through hole 33 into contact with dog l8 to retract the same, and. while thus retracted the handle can be screwed into member l0 whereupon the pin or wire is withdrawn from hole 33 and the do is forced by spring 22 into interengagement with a keeper 24 in member 10.

To remove the handle from member ID, the

escutcheon 6 and trimming 2 are first pushed down to uncover hole 33 whereupon a pin or wire can be inserted through hole 33 into contact with dog I8 to release the same preparatory to tuming the handle out of member I 0.

I claim:

1. A handle assembly comprising a handle, a rotatable spindle, cooperating means on said spindle and handle whereby the handle is secured to the spindle by rotating the handle relative to the spindle, a diametrically extending re cess in the handle, a spring pressed dog mounted in the recess, a plurality of circumferentially spaced recesses in the spindle one of which is adapted to interengage the dog to lock the handle the spindle can be rotated by turning said handle in either direction, and a plunger carried by the handle engageable with the dog for retracting.

the dog preparatory to disconnecting the handle from the spindle.

2. A handle assembly comprising a handle having a threaded hub, a spindle having a threaded opening therein whereby the hub of the handle can be screwed into the threaded opening in the spindle, a radially extending recess in the hub, a pivoted dog in said recess, a spring in said recess for projecting said dog into interengagement with said spindle, an axially extending opening in the handle communicating with the recess, a plunger reciprocably mounted in the axial opening, one end of which engages the dog and the other end of which extends to the outside of said handle whereby the plungercan be manually depresscd to retract the dog and permit the handle to be turned out of the spindle.

3. A handle assembly comprising a handle member, a rotatable spindle member, cooperating .15 against turning relative to the spindle whereby tion, the said handle member being provided with a plunger one end of which engages the dog and the other end of which is accessible from without the handle whereby the plunger can be depressed to retract the dog from its keeper to permit the handle to be removed from the spindle.

4. A handle assembly comprising a handle having an externally threaded hub, a rotary spindle havin a threaded openin therein whereby the hub of the handle can be screwed into the threaded opening in the spindle, a radially extending recess in the hub, a dog pivoted in said recess on a pivot offset from the axis of said hub, a longitudinally extending recess in the spindle adapted to interengage the dog to lock the handle against turning relative to the spindle, a spring in said first named recess for projecting said dog into interengagement with the recess in said spindle, an opening passing through said handle and communicating with said" diametrical recess, said dog having a projection extendin adjacent the inner end of said last mentioned opening whereby said dog can be disengaged from the recess in the spindle by means of an instrumentality passing through said last mentioned opening and contacting said projection on the dog.
