Abstract
The present disclosure defines a lever handing apparatus that permits simplified changing of the handing of a lever handle between a left hand and a right hand orientation. The lever handing apparatus includes an assembly with a rotatable spring cage housing and lever spindle that can be selectively rotated within an escutcheon housing to change the handing position of a lever arm. The handing orientation of the lever can be repositioned without removing a back plate or accessing internal components positioned within the escutcheon housing assembly.
Claims19
A lockset, comprising:
- a latch assembly;
- a housing assembly;
- a lever handle movably mounted to the housing assembly for rotational movement about a rotational axis and for axial movement along the rotational axis, wherein the lever handle is operably connected with the latch assembly;
- and
- a lever handing assembly operable to selectively provide the lever handle in each of a first handing orientation and a second handing orientation different from the first handing orientation;
- wherein axial movement of the lever handle along the rotational axis from a first position to a second position moves the lever handing assembly from an engaged condition to a disengaged condition;
- wherein, with the lever handing assembly in the engaged condition, the lever handle is provided in one of the first handing orientation or the second handing orientation;
- and
- wherein, with the lever handing assembly in the disengaged condition, the lever handle is movable between the first handing orientation and the second handing orientation.
6 more elements
A lockset, comprising:
- a housing assembly;
- a spring cage housing movably mounted to the housing assembly, wherein the spring cage housing is movable relative to the housing assembly along a rotational axis between an engaged position and a disengaged position;
- and
- a spindle rotatably mounted to the spring cage housing for rotation about the rotational axis and axially coupled with the spring cage housing for joint movement with the spring cage housing along the rotational axis;
- wherein, with the spring cage housing in the engaged position, the spring cage housing is rotationally coupled with the housing assembly;
- wherein, with the spring cage housing in the disengaged position, the spring cage housing is rotatable relative to the housing assembly between a first handing orientation and a second handing orientation;
- and
- wherein the spring cage housing is configured to move between the engaged position and the disengaged position in response to joint axial movement of the spindle and the spring cage housing along the rotational axis.
5 more elements
A lockset, comprising:
- a housing assembly;
- a spring cage housing movably mounted to the housing assembly for movement between an engaged position and a disengaged position;
- and
- a spindle rotatably mounted to the spring cage housing for rotation about a rotational axis;
- wherein the spring cage housing is configured to move between the engaged position and the disengaged position in response to axial movement of the spindle along the rotational axis;
- wherein one of the housing assembly or the spring cage housing comprises a first engagement feature;
- wherein the other of the housing assembly or the spring cage housing comprises a second engagement feature and a third engagement feature;
- wherein, with the spring cage housing in the disengaged position, the first engagement feature is disengaged from each of the second engagement feature and the third engagement feature, and the spring cage housing is rotatable relative to the housing assembly about the rotational axis between a first handing orientation and a second handing orientation different from the first handing orientation;
- wherein, with the spring cage housing in the engaged position and the first handing orientation, the first engagement feature and the second engagement feature are engaged with one another to prevent rotation of the spring cage housing relative to the housing assembly about the rotational axis;
- and
- wherein, with the spring cage housing in the engaged position and the second handing orientation, the first engagement feature and the third engagement feature are engaged with one another to prevent rotation of the spring cage housing relative to the housing assembly about the rotational axis.
