Locking device with configurable electrical connector key and internal circuit board for electronic door locks

Abstract

Locks, systems and methods of monitoring a lock, the lock having a hub with a slot rotatable by a handle to open and close a latchbolt. A locking member is moveable into and out of engagement with the hub slot to prevent and permit movement of the hub and latchbolt. A sensor on the lock, adjacent the hub and locking member, monitors a moving lock component. The sensor may sense the position of the locking member in or out of engagement with the hub slot. The sensor may be a reed switch actuated by a magnet on the moving lock component. The lock may further include a magnet mounted on the hub and the sensor may comprise a reed switch capable of being actuated by the magnet on the hub. The lock and system may include an external control unit having an alarm for controlling operation of the lock.

Overall, this patent provides a unified design that enables flexibility and future-proofing capabilities.

Problems solved by technology

Problems arise in making multiple connections between the electronic door lock components and an external control unit.

Such problems also encompass the connectors, the wiring harness and the selection of sensors within the lock that are to be made available to the external control unit.

This is labor intensive and expensive as well as making it difficult to keep the many variations in stock for rapid delivery to customers.

Due to constrained real estate in a majority of currently available locks, it has also become difficult and burdensome to provide the necessary wiring into and throughout the lock for the electrical connection between the switches, sensors and actuators in the lock and the electronic circuitry external to the lock.

Concerns are also raised when too much electrical wiring resides external to the locking device.

Insulated wire harnesses routed through a lockbody are subject to damage from contact with mechanical components.

It is also undesirably burdensome, time consuming, expensive and expends valuable real estate within the lock by requiring the lock casing to be fabricated with a number of holes and slots for accommodating the inserted wiring, as well as to be fabricated with brackets or harnesses inside the lock for securing and positioning the wiring accommodated therein.

As such, these conventional mortised recess and escutcheon-type lock assemblies suffer from fabrication difficulties as well as performance limitations in providing accurate wire routing to switches, actuators, and wire harnesses within existing mechanical lock mechanisms having constrained real estate.
