'f 'This invention relates `to handle assemblies, fpar-tioulafrly aninside handle for an automobile ,b-ody.

It is the object of the invention f to provide a 'rhandle assembly in which the handle unit may be easily'finstalled andxeasily removed. It is customary with inside handles for automobile AVbodies, particularly the regulator'handle and the lock handle, to use amescutcheon. This'escutchfreen is held out against the handle by means of feitherfthepadding on the door panel orfby a 4coil spring. This invention relates toan assembly Yof this type in which ythe escutcheon may be f pressed inwardly,'exposlng a sleeve which may A"be manipulated lby aproper tool to engage or `disengage the handle and spindle unit from the housing'member in which the handle spindle isy 'supported.

`= ,Int'he mass production `of automobile doors and automobile bodie'sthev doors are `often man- '-;u"factured in a. plant remote from the plant ifwhere the vbodies are manufactured. Heretofore, itha's been-customary to insert the hardware, :such asthe window regulator, locks, etc., inthe "doors in' the fplant where they are. manufactured andbefore they are shipped. In most,if not all, :'o'f' the designs heretofore produced, the window regulator and lock spindles are a part of thelock "or Window regulator rmechanismfand protrude .from the inside panel of the door. Consequently,

it 'is'v diicult to` stack and Iship these Without lthe vprotruding spindles interferr'ing wlth'the :stacking and'often marring or injuringvthe 1pane'1s.'

`It is lthe object ofthe present invention to 'afford a rhandle assembly in which the spindle `.is lpart; `of the handle itself so `that the -spindle control lock may be inserted inthe door panel after Yit is `Fig.4 is a section on the line 4-4 .of Fig. 3.

A stamped metal .escutcheon .is pressed outwardly yagainst fthe shoulderfof -thegripfportion fof the handle by ffmeans y01 thecoil spring 2l. Referring to lFig. 6 it will be seen that the rotatable sleeve .has at its lower ends stamped-'out lugsgz22. Each of these :lugs has stamped 'thereina `detent 23 l(see V4)y arranged -to yengage the recess24 stamped in the outer-housing -memberf5 (-see FigsqZ and 4).

This completes the sub-assembly of the driving parts.

The driven parts and housing are assembled by first projection-welding the flanged hub 8 to the crank. See these parts so welded in Fig. 2. The flanged hub, before it is Welded, has a boss 21 to permit this projection-welding (see Fig. 8). The hanged bearing sleeve 1 is then spot or projection-welded to the outer housing stamping 5 as shown in both Fig. 2 and the exploded view (Fig. 6). The crank 9 has a sleeve portiong28 which form a hub for the crank and fits into thev bearing sleeve 29 stamped out of the inner housing stamping 6. The welded unit comprising the hub 8 and the crank 9 is first set in place inthe housing plate 6, the hub 28 being set in the bearing sleeve 29. Thereupon, the outer housing stamping 5, together with the bearingsleeve 1 Welded thereto, is telescoped over the hub 8 as shown in Fig. 2. Then the two housing stampings 5 and 6 are riveted together with the rivets 30 shown in Fig. 1. This-completes the' driven sub-assembly. This sub-assembly is then bolted to the indented portion 2 of the inner panel I by means of the bolts 3 which pass through slots 3| and 32 in the housing stampings. Nutsr 33 are threaded on the ends of the bolts.

Now to assemble the two sub-assemblies: trimming material has already been stretched over the space formed by the indented portion 2 '2 of the inner door panel I and the spring 2l set in between the housing and the'trimming material. The escutcheon 20 is then placed over the trimming material as shown in Fig. 2. Then the handle sub-assembly is passed through the opening in the escutcheon and the lugs 33 are passed through'the two recesses 3'I of the housing (see Fig. 3). The handle and the sleeve are then pressed down, the teeth 34 of the spindle passing andtakes a tool, such as shownat 38 in Fig. 11, '.and inserts the nub 39 of the tool in one of the recesses 48 of the sleeve. The sleeve may then be turned, bringing the lugs from a position of registry with the recesses 3'I (Fig. 3) to a right- :angular position with respect to said recesses,` as shown in the dotted lines of Fig. 3. Spring 25 is now allowed to expand and it causes the lugs to press against the under side of the housing member 5, the detent 23 locking in the detent recess 24, as shown in Fig. 4. This completes the assembly.

The disassembly may be made by simply pressing in the escutcheon, inserting the tool 38 with the nub in the recess 4U, and turning the sleeve 'gone quarter of a turn.

` sembly partially into the drivensub-assembly and then turning the sleeve with a tool through `a part of a turn on the said spindle.
