Abstract

The door handle assembly includes a housing which is mounted in the door of a vehicle. A lever handle is pivotally connected to the front side of the housing by a pin, while a pivot plate is pivotally connected to the back side of the housing. The back side of the housing includes a curved channel in which is mounted a compression spring. The pivot plate lies in covering relation to the channel so as to retain or close the spring in the channel. The pivot plate includes an elongated arm which is linked to the door latch. Upon actuation of the handle, the pivot plate 14 is pivoted by a leg of the handle extending through the housing. The pivotal movement of the pivot plate compresses the spring between one end of the channnel and an arm on the pivot plate. The linkage between the pivot plate and one door latch releases the latch when the pivot plate is rotated by actuation of the handle. Upon release of the handle, the compression spring 36 biases the pivot plate to its normal at-rest position. A pin retention member extends from the housing for retaining the door handle pin in position. The pin retention member is integrally formed with the housing and is resilient. As the pin is inserted in aligned holes in the housing and the handle, the pinhead is pushed beyond the pin retention member so as to be captured thereby and preclude accident removal or inadvertant loss of the pin from the holes, without the use of additional hardware to retain the pin. The pin is installed in the holes and retained by the retention member in a single step.

Claims

1. An improved door handle assembly including a housing, a handle pivotally connected to the housing for movement about a first axis, and a pivot plate pivotally mounted on the housing and linked to a door latch, the pivot plate being actuated by the handle to release the door latch, the improvement comprising:

a curved channel formed on the housing;

a compression spring housed within the channel and engaged with the pivot plate to normally bias the plate and handle to a closed position, and the spring being compressed about a second axis by the pivot plate upon lifting of the handle; and

the first and second axes being substantially perpendicular to one another.

2. The improved assembly of claim 1 wherein the channel has an open top for receipt of the spring, and the spring is retained in the channel by the pivot plate.

3. The improved assembly of claim 1 wherein spring has opposite ends, the channel has one closed end to retain one end of the spring, and the pivot plate has a tab for retaining the opposite end of the spring.

4. The improved assembly of claim 1 wherein the channel is free from protrusions extending into the spring.

5. The improved assembly of claim 1 wherein the spring is retained without use of protrusions extending into the spring.

6. The improved assembly of claim 1 wherein the spring has a first end engaged by an arm on the pivot plate and a second end engaged by an end wall of the channel, such that upon actuation of the pivot plate, the spring is compressed between the pivot plate arm and the channel end wall.

7. The improved assembly of claim 1 wherein the channel has opposite side walls to control compression of the spring.

8. A door handle assembly comprising:

a housing with front and bask sides;

a handle pivotally connected to the front side of the housing for movement about a handle axis;

a curved channel formed on the back side of the housing;

a compression spring in the channel;

a pivot plate pivotally mounted on the back side of the housing for movement about a plate axis and being in covering relation to the channel to retain the spring in the channel;

the handle having a leg extending through the housing to engage the pivot plate and pivot the plate upon actuation of the handle; and

the handle axis and plate axis being non-coextensive with one another.

9. The door handle assembly of claim 8 wherein the spring has a first end engaged by an arm on the pivot plate and a second end engaged by an end wall of the channel, such that upon actuation of the pivot plate, the spring is compressed between the pivot plate arm and the channel end wall.

10. The door handle assembly of claim 8 wherein the channel has opposite side walls to control compression of the spring.

11. The door handle assembly of claim 8 wherein spring has opposite ends, the channel has one closed end to retain one end of the spring, and the pivot plate has a tab for retaining the opposite end of the spring.

12. The door handle assembly of claim 8 wherein the channel is free from protrusions extending into the spring.

13. The door handle assembly of claim 8 wherein the spring is retained without use of protrusions extending into the spring.

14. The door handle assembly of claim 8 wherein the handle axis is substantially perpendicular to the plate axis.
