An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.

Electro-mechanical lock core

A surgical footswitch for controlling a surgical instrument. The surgical footswitch includes a base. A treadle is rotatably coupled to the base to operate the surgical instrument. A foot guard is also rotatably coupled to the base. A blocking portion of the foot guard is configured to prevent physical access to the treadle in a lateral direction in a first position and permit access to the treadle in a lateral direction in a second position. A floor engagement portion of the foot guard engages a floor surface when the blocking portion is in the first position. The floor engagement portion is spaced from the floor surface when the blocking portion is in the second position. The floor engagement portion permits physical access to the treadle in a longitudinal direction when the blocking portion is in both the first position and the second position.

Footswitch for controlling surgical instruments and related accessories

A removable lock core for use with a lock device having a locked state and an unlocked state is disclosed. The removeable lock core may include a cam member tailpiece which is moveable between a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which permits removal of the removeable lock core from the lock device which corresponds to the lock device being in the unlocked state. The removeable lock core may include an electro-mechanical drive assembly which in a disengaged state is decoupled from the cam member tailpiece and in an engaged state is coupled to the cam member tailpiece. A cam lock having a locked state and an unlocked state for use with a catch is disclosed.

The present disclosure generally relates to a lock including a blocker (e.g., a bolt) useable to selectively prevent access through a portal such as a door. The blocker can be retained in a blocking position to prevent access through the portal by a retainer. In alternative embodiments, the blocker can also be retained in an open position to allow access through the portal. A retainer can be utilized to retain the blocker in the blocking position preventing access through the portal and can also be utilized, in certain embodiments, to retain the blocker in the open position to allow access through the portal. A retainer blocker can be utilized to maintain the retainer in position to retain the blocker (e.g., bolt) in a fixed position. An actuator may, in certain alternative embodiments, be employed to position the retainer blocker. In certain embodiments, the actuator is controlled by an electronic controller.

Electronic lock

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to the envelope of the lock core body to permit removal.

An exemplary electric strike includes a housing and a keeper pivotally mounted in the housing. The strike also includes a plunger having an extended position and a retracted position, a cage including an aperture, and a locking element movably seated in the aperture. The locking element is engaged with the plunger, and the plunger is structured to urge the locking element radially outward as the plunger moves from an extended position toward a retracted position. The strike also includes a sleeve, a transmission engaged with the sleeve, and a motor drivingly coupled to the transmission. The sleeve is structured to selectively prevent radially outward movement of the locking element and retraction of the plunger. The strike also includes at least one of a lost motion connection and an anti-tamper mechanism.

Motorized electric strike

An electro-mechanical lock for use with a lock device having a locked state and an unlocked state is disclosed. The electro-mechanical lock incorporates an actuation motor susceptible to lockdown and features a variety of lockdown mitigation structures and arrangements to combat the same.

Knob

A puller assembly for use with a lock device is disclosed. The lock device may have an interchangeable core. The puller assembly includes a puller core body having an opening sized to receive at least a portion of an operator actuation assembly of the lock device, a first engagement surface positioned to engage a portion of a rear end of the operator actuation assembly of the lock device, a second engagement surface positioned to engage a portion of a front end of a core assembly of the lock device, and an actuator which is moveable to alter a separation between the first engagement surface and the second engagement surface.
