Abstract
Lock indicators useable to signal the locked or unlocked state of a lock at both sides of a door selectively secured by the lock. Lock indicators include a first cuff for receiving an input causing the first cuff to transition from a first position to a second position associated with the locked state and the unlocked state. The lock indicators include a second cuff for receiving input from the first cuff via a transmission rod causing the second cuff to transition from a first position to a second position associated with the locked state and the unlocked state.
Claims20
A lock indicator mechanism for a lock on a door comprising:
- a locking lug transitionable between a locked position locking the lock and an unlocked position unlocking the lock;
- a first cuff operable to be positioned on a first side of a door, the first cuff operable to be positioned in a locked display position when the locking lug is in the locked position and operable to be positioned in an unlocked display position when the locking lug is in the unlocked position, the first cuff including a transmission actuator;
- a first lock indicator operably coupled with the first cuff;
- a second cuff positioned coaxially relative to the first cuff and operable to be positioned on a second side of the door, the second cuff including a transmission receiver;
- a second lock indicator operably coupled with the second cuff;
- and
- a transmission rod extending between the first cuff and the second cuff and operable to transmit motion from the first cuff to the second cuff via the transmission actuator of the first cuff and the transmission receiver of the second cuff, the transmission rod positioned radially outward from the first cuff and the second cuff.

A cylindrical lock comprising:
- a latch moveable between an engaged position operable to limit ingress and egress and a disengaged position not operable to limit ingress and egress;
- an egress actuator operable to receive a first operator input motion to actuate the egress actuator to move the latch from the engaged position to the disengaged position;
- an ingress actuator operable to receive a second operator input motion to actuate the ingress actuator to move the latch from the engaged position to the disengaged position;
- a lock input actuatable between a locked position and an unlocked position, the locked position of the lock input positioning the lock in a locked condition blocking the first and second the latch from moving from the engaged position to the disengaged position;
- a first indicator having a lock signal signaling the locked position of the lock input and an unlock signal signaling the unlocked position of the lock input, the first indicator selectively displaying only one of the lock signal and the unlock signal, the first indicator having a lock signal display position in which the lock signal is displayed and an unlock signal display position in which the unlock signal is displayed;
- a second indicator having a lock signal signaling the locked position of the lock input and an unlock signal signaling the unlocked position of the lock input, the second indicator selectively displaying only one of the lock signal and the unlock signal, the second indicator having a lock signal display position in which the lock signal is displayed and an unlock signal display position in which the unlock signal is displayed, the second indicator and the first indicator positioned about a first longitudinal axis;
- and
- a transmission rod operably coupling the first and second indicators such that when the first indicator displays the lock signal the second indicator displays the lock signal and such that when the first indicator displays the unlock signal the second indicator displays the unlock signal, the transmission rod having a second longitudinal axis spaced apart from the first longitudinal axis.

- a locking lug transitionable between a locked position locking the lock and an unlocked position unlocking the lock;
- a first cuff operable to be positioned on a first side of a door, the first cuff operable to be positioned in a locked display position when the locking lug is in the locked position and operable to be positioned in an unlocked display position when the locking lug is in the unlocked position, the first cuff including a transmission actuator;
- a first lock indicator operably coupled with the first cuff;
- a second cuff operable to be positioned on a second side of the door, the second cuff including a transmission receiver;
- a second lock indicator operably coupled with the second cuff;
- a transmission rod extending between the first cuff and the second cuff and operable to transmit mod on from the first cuff to the second cuff via the transmission actuator of the first cuff and the transmission receiver of the second cuff;
- and
- a hub including a first channel and a second channel, wherein the locking lug includes an engagement portion operable to be positioned in the first channel of the hub when the locking lug is in the locked position and operable to be positioned in the second channel of the hub When the locking lug is in the unlocked position.
