Abstract
An exemplary rotation converter includes an input component, an output component, and an intermediate component engaged between the input component and the output component. The input component is rotatable from an input component home position in each of a first direction and an opposite second direction. The intermediate component is configured to move to an actuated position in response to rotation of the input component in either direction, and to rotate the output component in an actuating direction as the intermediate component moves to the actuated position.
Claims20
A method, comprising:
- positioning a rotation converter at a location within a door having a first side and a second side, the rotation converter comprising an output member, an input member, and a shuttle engaged between the output member and the input member, wherein the shuttle is configured to rotate the output member in a first rotational direction in response to each one of (a) rotation of the input member in the first rotational direction, and (b) rotation of the input member in a second rotational direction opposite the first rotational direction;
- wherein, with the rotation converter positioned at the location within the door, the shuttle is positioned between the first side of the door and the second side of the door, and at least a portion of the input member is positioned between the first side of the door and the second side of the door.
A rotation converter, comprising:
- a housing comprising a first bearing aperture and a second bearing aperture aligned with the first bearing aperture along a rotational axis;
- an input member rotatably supported by the first bearing aperture for rotation about the rotational axis;
- an output member rotatably supported by the second bearing aperture for rotation about the rotational axis, the output member comprising a toothed region;
- and
- a shuttle engaged between the input member and the output member, the shuttle comprising a first rack and a second rack;
- the shuttle configured to rotate the output member in an output member actuating direction in response to each one of (a) rotation of the input member in a first rotational direction and (b) rotation of the input member in a second rotational direction opposite the first rotational direction;
- wherein the rotation converter has a first configuration in which the toothed region is engaged with the first rack and the output member actuating direction is the first rotational direction;
- and
- wherein the rotation converter has a second configuration in which the toothed region is engaged with the second rack and the output member actuating direction is the second rotational direction.
A system, comprising:
- a pushbar assembly comprising a first rear surface configured to abut a first side of a door;
- a trim assembly comprising a second rear surface that faces the first rear surface and is configured to abut a second side of the door opposite the first side of the door;
- and
- a rotation converter removably engaged with each of the pushbar assembly and the trim, wherein the rotation converter comprises an input member and a shuttle configured to rotate an output member in an output member actuating direction in response to each one of (a) rotation of the input member in a first rotational direction and (b) rotation of the input member in a second rotational direction opposite the first rotational direction;
- wherein the shuttle is positioned between the first rear surface and the second rear surface;
- and
- wherein the input member is positioned at least partially between the first rear surface and the second rear surface.
