Abstract

A door handle assembly includes a door handle having an operator portion, and a shank extending from the operator portion, the shank having a first opening. A door latch mechanism has a rotatable actuator, the rotatable actuator having a second opening. A spindle assembly includes a spindle and a spring. The spindle has a first end and a second end. The spring is attached to the first end of the spindle. The spring and the first end of the spindle of the spindle assembly are inserted as a unit into the first opening of the shank of the door handle, and the second end of the spindle is inserted into the second opening of the rotatable actuator of the door latch mechanism.

Claims (31)

1. A door handle assembly, comprising:

a door handle having an operator portion, and a shank extending from said operator portion, said shank having a first opening;

a door latch mechanism having a rotatable actuator, said rotatable actuator having a second opening; and

a spindle assembly including a spindle and a coil spring, said spindle having a first end and a second end, said coil spring having a normal inside diameter that is expandable to a second diameter, said first end of said spindle having a cross sectional diameter that is greater than said normal inside diameter of said spring, said coil spring being attached to said first end of said spindle by inserting said first end of said spindle into said coil spring when at said second diameter and permitting said coil spring to release back toward said first diameter to form a snug fit of said coil spring to said first end of said spindle,

wherein said coil spring and said first end of said spindle of said spindle assembly are inserted as a unit into said first opening of said shank of said door handle, and said second end of said spindle is inserted into said second opening of said rotatable actuator of said door latch mechanism.

2. A door handle assembly, comprising:

a door handle having an operator portion, and a shank extending from said operator portion, said shank having a first opening;

a door latch mechanism having a rotatable actuator, said rotatable actuator having a second opening; and

a spindle assembly including a spindle, a coil spring and a limiter, said spindle having a first end and a second end, said coil spring being attached to said first end of said spindle in a snug fit attachment wherein said coil spring is expanded from a normal diameter to an expanded diameter, said first end of said spindle is inserted into the expanded coil spring, and said coil spring is released from said expanded diameter to return toward said normal diameter,

said limiter forming a part of said spindle assembly being attached to said spindle near said second end of said spindle to limit an extent that said second end of said spindle is inserted into said second opening of said rotatable actuator of said door latch mechanism.

3. The door handle assembly of claim 2 , wherein said limiter is a C-clip that engages a groove in said spindle.

4. A door handle assembly, comprising:

a door handle having an operator portion, and a shank extending from said operator portion, said shank having a first opening;

a door latch mechanism having a rotatable actuator, said rotatable actuator having a second opening; and

a spindle assembly including a spindle and a spring, said spindle having a first end and a second end, said spring being attached to said first end of said spindle,

wherein said spring and said first end of said spindle of said spindle assembly are inserted as a unit into said first opening of said shank of said door handle, and said second end of said spindle is inserted into said second opening of said rotatable actuator of said door latch mechanism, wherein:

said spring is a coil spring having a proximal end and a distal end, said proximal end of said coil spring having a normal inside diameter that is expandable to a second diameter;

said spindle includes a spindle body and a spindle post axially aligned with said spindle body along an axis, said spindle post having a dimension perpendicularly intersecting said axis, said dimension is greater than said normal inside diameter of said spring; and

said spindle post of said spindle is inserted into said proximal end of said coil spring to form a snug fit attachment of said coil spring to said spindle.

5. A spindle assembly for a door handle assembly, comprising:

a spindle having a first end and a second end; and

a coil spring having a normal diameter and an expanded diameter, said spring being attached to said first end of said spindle by a snug fit of said spring to said first end of said spindle wherein said coil spring is expanded from said normal diameter to said expanded diameter, said first end of said spindle is inserted into the expanded coil spring, and said coil spring is released from said expanded diameter to return toward said normal diameter wherein said coil spring and said first end of said spindle of said spindle assembly are insertable as a unit into a first opening of a shank of a door handle, and said second end of said spindle is insertable into a second opening of a rotatable actuator of a door latch mechanism.

6. A spindle assembly for a door handle assembly, comprising:

a spindle having a first end and a second end; and

a spring attached to said first end of said spindle, wherein:

said spring is a coil spring having a proximal end and a distal end, said proximal end of said coil spring having a normal inside diameter that is expandable to a second diameter;

said spindle post of said spindle is inserted into said proximal end of said coil spring to form a snug fit attachment of said coil spring to said spindle wherein said coil spring and said first end of said spindle of said spindle assembly are insertable as a unit into a first opening of a shank of a door handle, and said second end of said spindle is insertable into a second opening of a rotatable actuator of a door latch mechanism.

7. The spindle assembly of claim 6 , further comprising a limiter attached to said spindle body.

8. The spindle assembly of claim 7 , wherein said limiter is a C-clip that engages a groove in said spindle body.
