Abstract
A handle operably coupled to rotating door handle assembly is disclosed. The handle may include a first rotatable member configured to engage a door latch mechanism. The handle may further include a second member mechanically engaged with the first member and the second member may be extended a length between a non-extended position and an extended position. A handle cavity may be defined within at least a portion of the second member and a bar may be enclosed within the handle cavity. Furthermore, an extension mechanism may be incorporated with the bar and the second member and configured to extend the bar from the cavity when the second member is in the extended position and retract the bar within the cavity when the second member is in the non-extended position.
Claims21
A handle comprising:
- a first rotatable member configured to engage a door latch mechanism;
- and
- a second member having a first end mechanically engaged with the first rotatable member and a second end opposite the first end, wherein the second member includes a non-extendable portion mechanically engaging the first rotatable member and an extendable portion operatively coupled to the non-extendable portion and moveable relative to the non-extendable portion between a non-extended position and an extended position, wherein the non-extendable portion and the extendable portion are in contact when the second member is in the retracted position and the non-extendable portion and the extendable portion are separated from each other when the second member is in the extendable position, and wherein a length of the second member from the first end to the second end is adjustable between the non-extended position with a first handle length and the extended position with a second handle length that is greater than the first handle length such that a lower external force at the second end of the second member is required to rotate the first rotatable member when the second member is in the extended position than when the second member is in the non-extended position.
A door handle assembly operably coupled to a door, the door handle assembly comprising:
- a latch mechanism operably coupled to the door;
- a mounting plate attached to a surface of the door;
- a first rotatable member coupled to the mounting plate and configured to engage the latch mechanism;
- and
- a second member having a first end mechanically engaged with the first rotatable member and a second end opposite the first end, wherein the second member includes a non-extendable portion mechanically engaging the first rotatable member and an extendable portion operatively coupled to the non-extendable portion and moveable relative to the non-extendable portion between a non-extended position and an extended position, wherein the non-extendable portion and the extendable portion are in contact when the second member is in the retracted position and the non-extendable portion and the extendable portion are separated from each other when the second member is in the extendable position, and wherein a length of the second member from the first end to the second end is adjustable between the non-extended position with a first handle length and the extended position with a second handle length that is greater than the first handle length such that a lower external force at the second end of the second member is required to rotate the first rotatable member when the second member is in the extended position than when the second member is in the non-extended position.
A door handle assembly operably coupled to a door, the door handle assembly comprising:
- a latch mechanism operably coupled to the door;
- a mounting plate attached to a surface of the door;
- a first rotatable member coupled to the mounting plate and configured to engage the latch mechanism;
- an extendable handle including a non-extendable portion having a first end of the extendable handle and an extendable portion having a second end of the extendable handle opposite the first end, the extendable handle mechanically engaged with the first rotatable member at the first end;
- and
- a bar extendably coupled between the non-extendable portion and the extendable portion, wherein the bar extends a length between the non-extendable portion and the extendable portion to adjust the extendable handle between a non-extended position with a first handle length and an extended position with a second handle length that is greater than the first handle length such that a lower external force at the second end of the extendable handle is required to rotate the first rotatable member when the extendable handle is in the extended position than when the extendable handle is in the non-extended position.
