Abstract

A lockset is actuable by pivoting a handle about a longitudinal axis of the lockset by rotating the handle and by pivoting the handle about an axis transverse to the lockset axis, such as by pushing or pulling. The lockset includes an inside handle and an outside handle, each associated with an independent mechanism, each of which can independently actuate the lockset. A locking mechanism prevents actuation of a first one of the independent handle mechanisms without affecting operation of the other handle mechanism. Upon actuation of the other handle mechanism, a retractor engages a surface of the locking mechanism and removes it from engagement with the first locking mechanism. An adjustment ring has a first configuration that centers the lockset in a door having a first standard thickness and a second configuration that centers the lockset in a door having a second standard thickness.

Claims21

Dependent claims

A lockset, comprising:

a first actuating mechanism configured to receive an input from a first handle so that when the first handle is actuated, the first actuating mechanism urges a first retractor arm to rotate;
a second actuating mechanism configured to receive an input from a second handle so that when the second handle is actuated, the second actuating mechanism urges a second retractor arm to rotate;
the first and second retractor arms being disposed on opposite sides of a lockset axis;
a retractor constrained so as to be movable in a direction transverse to the lockset axis, the retractor having first and second ends;
the first retractor arm extending through the first end of the retractor so that a distal end of the first retractor arm is within the retractor, and when the first retractor arm rotates, the first retractor arm distal end engages a contact surface of the retractor and urges the retractor to move in the direction transverse to the lockset axis;
the second retractor arm extending through the second end of the retractor so that a distal end of the second retractor arm is within the retractor, and when the second retractor arm rotates, the second retractor arm distal end engages the contact surface of the retractor and urges the retractor to move in the direction transverse to the lockset axis;
and
an elongate locking member movable between a locked position and an unlocked position, a control arm extending from and moving with the locking member, the control arm having a lock portion configured so that when the locking member is in the locked position the lock portion blocks the second retractor arm from rotating sufficient to engage the retractor contact surface;
wherein the first retractor arm is not blocked from rotation when the locking member is in the locked position;
and
wherein the control arm is configured so that when the retractor is moved by the first retractor arm when the locking member is in the locked position, the moving retractor engages a control surface that is attached to the locking member so as to urge the locking member from the locked position toward the unlocked position.

8 more elements

A method of operating a lockset having first and second actuating mechanisms that are configured so that when one of a first or second handles is actuated, a respective first or second retractor arm is urged to rotate, the method comprising:

moving an elongate locking member from an unlocked position to a locked position so that a control arm that extends from and moves with the elongate locking member is moved into a blocking position at which the control arm blocks the second retractor arm from rotating, the elongate locking member having a locking member axis that is spaced from a lockset axis;
actuating the first handle so that the first retractor arm rotates and a portion of the first retractor arm engages a retractor so as to push the retractor in an opening direction that is transverse to the lockset axis;
wherein as the retractor moves in the opening direction the retractor engages a control surface that is attached to the locking member, the control surface disposed at an angle oblique to the opening direction so that as the retractor moves in the opening direction the retractor engages and slides over the control surface, pushing the control surface and locking member toward the unlocked position;
wherein actuating the first handle moves the locking member from the locked position to the unlocked position.
