Abstract

Claims (31)

1. A door handle assembly comprising:

a bracket including a clip having a flexible arm and a catch disposed at an end of the arm;

a slide member coupled to the bracket and configured to translate between a first position and a second position;

an actuation screw that is rotatably coupled to the bracket and threadably coupled to the slide member via threads on the actuation screw and corresponding threads on the slide member, the actuation screw translating the slide member from the first position to the second position upon rotation of the actuation screw;

a lock cylinder including a cylindrical body having a projection extending outwardly from the cylindrical body, the projection being configured to engage with the catch to couple the lock cylinder to the bracket, wherein the slide member engages the lock cylinder in the second position; and

a counterweight pivotally coupled to the bracket and configured to rotate between a first rotational position and a second rotational position,

wherein, upon translation of the slide member from the second position to the first position, the slide member is operable to (i) rotate the counterweight in a first direction from the second rotational position to the first rotational position and (ii) prevent rotation of the counterweight in a second direction from the first rotational position.

2. The door handle assembly of claim 1 , further comprising an actuator operably coupled to the counterweight, wherein, upon translation of the slide member from the first position to the second position, the actuator is operable to rotate the counterweight in the second direction.

3. The door handle assembly of claim 1 , further comprising a handle rotatably coupled to the bracket, the handle including a body and a leg extending from the body and coupled to the counterweight, wherein the counterweight is configured to rotate the handle relative to the body upon rotation in the first direction and the second direction.

4. The door handle assembly of claim 3 , wherein the counterweight includes a hook and the leg includes a pin pivotally coupled to the hook.

5. The door handle assembly of claim 1 , wherein the counterweight includes an engagement surface and the slide member includes a guide surface, the guide surface configured to slidably engage the engagement surface to rotate the counterweight in the first direction.

6. A door handle assembly comprising:

a bracket including a clip having a flexible arm and a catch disposed at an end of the arm;

a slide member translatably coupled to the bracket and including an aperture;

an actuation screw that is rotatably coupled to the bracket and threadably coupled to the slide member via threads on the actuation screw and corresponding threads on the slide member, the actuation screw translating the slide member from the first position to the second position upon rotation of the actuation screw;

a lock cylinder configured to engage with the catch to having a cylindrical body disposed within the aperture and including projection extending outwardly from the cylindrical body, the projection being couple the lock cylinder to the bracket, wherein the slide member engages the lock cylinder in the second position;

a counterweight pivotally coupled to the bracket and having a handle-receiving portion;

a handle rotatably coupled to the bracket and having a leg portion pivotally received by the handle-receiving portion; and

an actuator operably coupled to the counterweight and configured to pivot the counterweight in a first direction,

wherein, the slide member is operable to pivot the counterweight in a second direction opposite the first direction.

7. The door handle assembly of claim 6 , wherein the slide member includes a stop surface operable to abut the counterweight and inhibit rotation of the counterweight in the second direction.

8. The door handle assembly of claim 6 , wherein, upon translation of the slide member from a first position to a second position, the actuator is operable to rotate the counterweight in the first direction.

9. The door handle assembly of claim 6 , wherein the counterweight is configured to rotate the handle in the first direction relative to the bracket.

10. The door handle assembly of claim 6 , wherein the handle-receiving portion includes a hook and the leg portion includes a pin pivotally coupled to the hook.

11. The door handle assembly of claim 6 , wherein the counterweight includes an engagement surface configured to slidably engage the slide member to pivot the counterweight in the second direction.

12. A method of assembling a door handle assembly, the method comprising:

coupling a door handle to a bracket and a counterweight, the counterweight pivotally supported by the bracket and the bracket including a clip having a flexible arm and a catch disposed at an end of the arm;

translating a slide member relative to the bracket by rotating an actuation screw that is rotatably coupled to the bracket and threadably coupled to the slide member via threads on the actuation screw and corresponding threads on the slide member to allow the counterweight to pivot relative to the bracket;

coupling a lock cylinder having a cylindrical body including extending outwardly from the cylindrical body to the bracket by engaging the projection with the catch; and

engaging the counterweight with the door handle to rotate the door handle relative to the bracket.

13. The method of claim 12 , wherein the lock cylinder is coupled to the bracket prior to coupling the door handle to the bracket, wherein rotating the door handle relative to the bracket includes disposing the lock cylinder within an aperture of the door handle.
