2 Claims.

This invention relates to outside handle assemblies, particularly for automobile door locks.

It is the object of the invention to provide an assembly in which the outside pull-to handle, the escutcheon and the operating connection between the swinging handle and the rollback of the lock are all assembled together as a unit.

It is old in the art to provide an outside pull-to handle, but these pull-to handles, so far as I am aware, are not mounted in a unit, bushing or escutcheon which also contains a rotating handle spindle with an operating connection between the pull-to handle and the spindle for converting the rotary motion in a horizontal plane to a rotary motion in a vertical plane.

Referring to the drawings:

Fig. 1 is a horizontal section showing one form of the bushing or escutcheon. This is a type used in connection with the belt molding oi the car.

' Fig. 2 is a cross section of the same taken on the line 22 of Fig. 1.

3 is a horizontal cross-section of a modifi cation.

' Fig. 4 is a side elevation of the handle spindle of the modified form.

Fig. 5 is an end elevation of the same handle spindle.

l designates the pull-to or pull-out handle which is pivoted on a vertical pin 2. This pin 2 is supported in the escutcheon or bushing I (called a supporting member" in the claims). The escutcheon is held in place by a screw 4 that passes through the outside face of the escutcheon into the outer door panel 5 and a second screw 6 which passes through the lamb face of the door into the escutcheon. The escutcheon itself is on the outside covered by a shell I which is part of the belt molding of the car. 9 represents another portion of the belt molding. The escutcheon has an arm I0 which extends through the inside of the outer door panel and is provided with a bearing II which supports the rotating spindle I! which has a squared end I! which fits into the rollback ll of the lock. The outer end of the spindle is provided with a crank arm I! which is engaged by the load am It oi the handle lever I. when the handlelever is pulled out to open the door the load arm I! of the lever bears against the end of theicrank arm I! on the spindle [2. This serves to convert the rotary motion on the vertical axis into a rotary motion on a horizontal axis thereby turning the spindle l2. and the rollback ll, retracting the lock bolt.

In the form of the invention shown in Fig. 3, the escutcheon takes the form of a cylindrical bushing II on which is mounted a similar pullto handle Ia that-engages a similar rotating spindle I211 which has a crank arm l5a to be engaged by the load arm lfia of the hand lever. A spring l8 tends to rotate the handle inwardly and thereby take up any looseness between the load arm Ilia and surface 2| on the escutcheon.

This, however, is alight spring which simply keeps the parts under spring pressure to avoid rattling and helps return the handle to its normal position after it has been operated.

One of the features of this assembly is when the bushing is set into the door through the outer panel 5a, a screw is passed through the opening IS in the jamb face of the door and secures the flattened portion 20 on the inner end of the handle spindle to the rollback Ila. Hence, when the screw secures the spindle to the rollback, it also serves to fasten the entire assembly in place without the use of other fastening devices, which makes he very simple assembly,

What I claim is:

1. A unit handle assembly for a pull-to handle of a door lock, having. in combination a supporting member which can be mounted in the door,

said supporting "member having an enlarged recessed portion and a smaller bearing portion having an opening therein,-the latter at the inner end of the supporting member, a spindle passed into the bearing opening through the enlarged recess, said spindle provided with a crank' arm which remains in the recess and provided at the inner end with a non-circular portion arranged to fit into the rollback of the lock and a hand lever of the pull-to type pivoted to swing on a pin passing transversely'across the recess of the supporting member near the outer end thereof. said hand lever provided with a load arm arranged to contact with the crank arm of the spindle and to convert the rotary motion of the hand lever in one plane into rotary motion of the spindle in a plane at right angles to the first mentioned plane.

2. A handle assembly for a pull-to handle, particularly an outside handle of an automobile door lock, having in combination a supporting member which can be mounted on the outside of the door and passes into the interior of the door, said supporting member provided with a spindle bearing at its inner end, a swinging hand lever pivoted on a pin located transversely of said supporting member, said hand lever provided with a load arm and a spindle rotatably supported in the spindle bearingof the supporting member and provided with a crank arm arranged to be contacted by the load arm of the hand lever, the said supporting member andthe hand lever and spindle being a unit assembly.
