Abstract

A handle for a vehicle door is mounted on a frame by a pivot assembly for swinging movement from a door latching position to a door unlatching position. The frame is secured in an interior space of the door in a position such that when the handle is in the latching position, the handle registers with an opening in a door panel, and when the handle is in the unlatching position, the handle extends into the interior space. The pivot assembly has a hinge which provides a floating axis for the swinging movement of the handle, enabling the handle to be shifted laterally outwardly into contact with a flange on the panel when in the latching position, thereby positioning the outer surface of the handle flush with the outer surface of the door panel. A spring urges the handle laterally outwardly into contact with the flange.

Claims

1. A door handle assembly for a vehicle door, comprising:

a mounting frame adapted to be mounted on a vehicle door,

a door handle, and

a pivot assembly comprising interengaging hinge parts on said frame and on said door handle mounting said door handle on said frame for swinging movement from a door latching position to a door unlatching position,

said hinge parts having a loose interengagement providing a floating axis for the swinging movement of said door handle and enabling said door handle to be shifted laterally inwardly and laterally outwardly, wherein

said door handle is biased laterally outwardly.

2. The door handle assembly of claim 1, wherein one of said hinge parts comprises a hinge pin and another of said hinge parts comprises a hinge knuckle having an aperture receiving said pin, said aperture being oversized relative to said pin.

3. The door handle assembly of claim 2, wherein said hinge pin is on said frame and said hinge knuckle is on said door handle.

4. The door handle assembly of claim 3, further including a switch for actuating a door latch unlatching mechanism to unlatch the vehicle door, wherein said switch is activated in response to the swinging movement of the door handle to the door unlatching position.

5. The door handle assembly of claim 4, further comprising a movable stem on said switch, the stem activating said switch when the stem is moved to an operative position, and a cam on said door handle engagable with said stem and moving said stem to said operative position in response to the swinging movement of said door handle to said door unlatching position.

6. A vehicle door and door handle assembly, comprising:

a vehicle door having an interior space defined in part by an outer door panel having an opening communicating with said interior space,

a mounting frame,

a door handle,

a pivot assembly comprising interengaging hinge parts on said frame and on said door handle mounting said door handle on said frame for swinging movement from a door latching position to a door unlatching position,

said mounting frame being secured to said vehicle door in the interior space of the vehicle door in a position such that when the door handle is in the door latching position, the door handle registers with and is generally parallel to the opening, and when the door handle is in the door unlatching position, the door handle extends into the interior space at a substantial angle to the opening,

said hinge parts having a loose interengagement providing a floating axis for the swinging movement of said door handle and enabling said door handle to be shifted laterally outwardly into contact with an abutment to a position of use in which an outer surface of said handle is flush with an outer surface of said door panel surrounding said opening, and

said door handle being biased laterally outwardly into contact with said abutment.

7. The vehicle door and handle assembly of claim 6, wherein said abutment comprises a flange on an inner surface of the door panel adjacent to said opening.

8. The vehicle door and handle assembly of claim 7, wherein said flange surrounds said opening and extends inwardly from the inner surface of said outer door panel.

9. The door handle assembly of claim 6, wherein one of said hinge parts comprises a hinge pin and another of said hinge parts comprises spaced apart hinge knuckles having aligned apertures receiving said pin, said apertures being oversized relative to said pin.

10. The door handle assembly of claim 9, wherein said hinge pin is on said frame and said hinge knuckles are on said door handle.

11. The vehicle door handle assembly of claim 10, wherein said abutment comprises an annular flange on an inner surface of the door panel adjacent to said opening, said annular flange surrounding said opening and extending inwardly from the inner surface of the outer door panel.

12. The vehicle door and handle assembly of claim 11, wherein said door handle has locator pads which engage said flange in the position of use.

13. The door handle assembly of claim 12, further including a switch for actuating a door latch unlatching mechanism to unlatch the vehicle door, said switch being activated in response to the swinging movement of the door handle to the door unlatching position.

14. The door handle assembly of claim 13, wherein said switch includes a movable stem, the stem activating said switch when the stem is moved to an operative position, and a cam on said door handle engagable with said stem and moving said stem to said operative position in response to the swinging movement of said door handle to said door unlatching position.

15. The door handle assembly of claim 14, wherein said door handle comprises a base to which said locator pads are attached, and a cover plate on which said outer surface of said handle is formed, said cover plate being removably attached to said base.
