The present disclosure relates to door lock assemblies, and particularly to a motor driven locking system that selectively engages and disengages a deadbolt or other latch to extend or retract the same.
An illustrative embodiment of the present disclosure provides an electro-mechanical lock assembly that is configured to automatically engage or disengage a latch, such as a deadbolt. For example, upon entry of an authorized pass code or other indication of authorization, a motor will cause engagement of mechanical parts coupled to the bolt or latch to allow it to be moved under manual means. In other words, upon entrance of a proper code, a motor moves a clutch-like member to engage both a drive and driven component. The drive component may then be manually moved, which moves the driven component, which moves the latch from the locked to unlocked position, or vice versa.
An illustrative embodiment of the present disclosure includes a keypad or another like system that requires a correct combination or key in order to engage the latch. If the correct combination is entered, power is supplied to a motor that rotates a shaft. A pin is attached to the shaft and rotates therewith with the motor. A spring wraps around the shaft that is configured to compress or expand by the pin and depending on the direction of rotation of the shaft. The spring engages a carriage that engages a spline-driver or flower that is moveable between a driver-torque housing and a gear part. When the flower engages both the driver-torque housing and the gear part at the same time, an illustrative bezel attached to the female gear part can be manually moved. Moving, such as rotating the bezel, will rotate the male gear part which rotates the driver-torque housing and blade, which causes the latch to move in one direction or another.
Another illustrative embodiment of the present disclosure provides an electro-mechanical lock assembly. The electro-mechanical lock assembly comprises a keypad, a motor, a gear, a spline-driver, a torque member, a housing, and a bezel. The motor is operable upon selective input to the keypad. The motor is also coupled to the spline-driver to engage both the gear and the housing when the motor is in operation. The bezel is attached to the gear such that when the spline-driver is engaged with both the gear and the housing, manual rotation of the bezel will rotate the housing. The housing is attached to the torque member which is configured to move a latch such that when the bezel rotates the latch is moved.
In the above and other illustrative embodiments, the electro-mechanical lock assembly may further comprise: a base located adjacent the bezel and configured to fit against a door; the keypad being configured to receive a combination code as the selective input to operate the motor; a cable ribbon in communication with a PCB board that determines if a proper combination code as the selective input is entered into the keypad to direct a signal to the motor to operate the motor; the cable ribbon being extendable from the electro-mechanical lock assembly and connectable to a battery case in a turnpiece assembly; the cable ribbon being supported by a support attached to the electro-mechanical lock assembly so the cable ribbon does not interfere with any backset assembly components that move a door latch or bolt; a drive rod being attachable to the motor; wherein the drive rod rotates as the motor operates; a pin extends transversely through the drive rod and rotates with the drive rod; a spring is wound around the drive rod; a second spring extends from the spline-driver to the housing; wherein the pin acts as a cam follower by engagement of the coil wire of the spring; engagement of the coil wire of the spring compresses or extends the spring along the longitudinal length of the drive rod; a carriage is movable back and forth along the drive rod such that as the spring expands or compresses the carriage is engagable with the spline-driver such that as the pin extends or retracts the spring, the spline-driver is likewise pulled or pushed; the second spring is in compression so it biases the spline-driver towards the pin; when the spline-driver is moved to a location that is between both the housing and the gear, manually rotating the bezel which is attached to the gear, it rotates the housing which is attached to and rotates the torque member; when the spline-driver is not engaged to both the housing and the gear, the housing will not rotate the torque member; the torque member being attached to the housing by a second pin; the turnpiece assembly includes a plate; a battery case; a button; vibration dampening pads; a rose; and a knob; and the button may engage a switch mechanism that is in communication with at least one battery in the battery case to send a signal through the ribbon cable to operate the motor.
Another illustrative embodiment provides an electro-mechanical lock assembly. It comprises a motor, a coupling, a driver, a torque member, a housing, and a bezel. The motor is coupled to the driver to engage both the coupling and the housing when the motor is in operation. The bezel is attached to the coupling such that when the driver is engaged with both the coupling and the housing, manual rotation of the bezel will rotate the housing. Lastly, the housing is attached to the torque member which is configured to move a latch such that when the bezel rotates the latch is moved.
In the above and other illustrative embodiment, the electro-mechanical lock assembly may further comprise: a base located adjacent the bezel and configured to fit against a door; a keypad configured to receive a combination code to operate the motor; a cable ribbon in communication with a PCB board that determines if a proper combination code as the selective input is entered into the keypad to direct a signal to the motor to operate the motor; the cable ribbon being extendable from the electro-mechanical lock assembly and connectable to a battery case in a turnpiece assembly; the cable ribbon being supported by a support attached to the electro-mechanical lock assembly so the cable ribbon does not interfere with any backset assembly components that move a door latch or bolt; a drive rod that is attached to the motor; wherein the drive rod rotates as the motor operates; a pin extends transversely through the drive rod and rotates with the drive rod; a spring is wound around the drive rod; a second spring extends from the driver to the housing; wherein the pin acts as a cam follower by engagement of the coil wire of the spring; engagement of the coil wire of the spring compresses or extends the spring along the longitudinal length of the drive rod; a carriage being movable back and forth along the drive rod such that as the spring expands or compresses, the carriage is engagable with the driver such that as the pin extends or retracts the spring the driver is likewise pulled or pushed; the second spring being in compression so it biases the driver towards the pin; when the driver is moved to a location that is between both the housing and the coupling, manually rotating the bezel which is attached to the coupling, rotates the housing which is attached to and rotates the torque member; when the driver is not engaged to both the housing and the coupling, the housing will not rotate the torque member; the torque member being attached to the housing by a second pin; the turnpiece assembly including a plate, a battery case, a button, vibration dampening pads, a rose, and a knob; and the button may engage a switch mechanism that is in communication with at least one battery in the battery case to send a signal through the ribbon cable to operate the motor.
