Abstract:

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.

E05B 17/20
E05B 17/00

Abstract:

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.

International Classification:

E05B 63/00

Abstract:

A puller for use with a lock device is disclosed. The lock device may have an interchangeable core. The puller may include a puller assembly, the puller assembly including 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.

Appl. No.:

15/640989

Inventors:

- Carmel IN, US
John Snodgrass - Indianapolis IN, US

International Classification:

F16C 1/22

Abstract:

An assembly for adjusting a cable that includes a locking sleeve and an adapter that is connected to the cable. The adapter includes male and female-threaded portions that are coupled together. The locking sleeve is configured to be displaced between engagement and disengagement positions. When in the engagement position, securing devices of the male and female-threaded portions engage inner sections of the locking sleeve in a manner that prevents the male and female-threaded portions from being rotated relative to each other, thereby preventing a change in the length of the adapter so as to prevent an adjustment of the cable. When the cable is to be adjusted, the locking sleeve is displaced to disengagement position such that the securing device of either the male or female-threaded portion is disengaged from the locking sleeve, thereby allowing rotation of the male or female-threaded portions relative to each other.
