Abstract
A cylindrical locking core suitable for retrofit and new installations has a coupling to releasably engage a driver in a locking system. The coupling, for example, a clip, has a base which fits into a channel in the core, to grasp the core. The clip also includes two opposing flexible, resilient arms to releasably grasp the driver. The arms have rigid flanges which engage recesses in the driver. The core may be disengaged from the driver by rotating the core relative to the driver, using a change key. When the core is in use, an operating key extends through the core and an opening in the coupling, to engage the driver, to open and close the lock system.
Claims20
A locking core for rotational operation within a lock housing,
- the core comprising a proximate and a distal end,
- the core defining a longitudinal axis and a cylindrical longitudinal surface between the proximate end and the distal end, the surface defining a channel,
- the channel defining a plane extending transversely across the axis,
- a flexibly resilient coupling comprising a base for removably engaging the channel,
- when in use, the coupling removably engages the core with a driver in a locking assembly,
- the coupling comprising a pair of opposing flexibly resilient arms for removably engaging a pair of corresponding recesses defined by the driver.
A cylindrical locking core for rotational operation within a lock housing in a locking assembly for selectively locking and unlocking a storage unit, the locking core defining a cylindrical surface along a longitudinal axis, between a proximate end of the locking core and a distal end of the locking core,
- the cylindrical surface defining a channel extending transversely across the axis,
- a flexibly resilient coupling comprising a base for removably engaging the channel, and
- when in use, the coupling releasably secures the locking core to a driver in the locking assembly,
- the coupling comprising a pair of opposing flexibly resilient arms extending coaxially away from the base, the arms being biased inwardly for movement toward the axis to engage the driver.
