Claims18
A lock, comprising:
- a retractable knob;
- and
- a knob release mechanism for retaining the retractable knob in a retracted position, the knob release mechanism retains the retractable knob in the retracted position until a motor of the knob release mechanism is actuated by an input provided to a keypad located on a surface of the lock wherein movement of the retractable knob from the retracted position to an extended position is dampened by a damper, wherein the retractable knob is spring biased into the extended position.
A lock, comprising:
- a retractable knob;
- and
- a knob release mechanism for retaining the retractable knob in a retracted position, the knob release mechanism retains the retractable knob in the retracted position until a motor of the knob release mechanism is actuated by an input provided to a keypad located on a surface of the lock, the knob release mechanism including a primary arm pivotally mounted to the knob release mechanism for movement between a first position and a second position and a secondary arm pivotally mounted to the knob release mechanism for movement between a first position and a second position, wherein the secondary arm is configured to retain the retractable knob in the retracted position when the secondary arm is in the first position, and wherein the motor further comprises a worm and the worm pivots the primary arm by engaging teeth of the primary arm.
A method releasing a retractable knob of a lock, comprising:
- spring biasing the retractable knob into an extended position;
- retaining the retractable knob in a retracted position by a knob release mechanism;
- releasing the retractable knob from the retracted position by actuating the knob release mechanism through an input provided to the lock;
- and
- damping movement of the retractable knob from the retracted position to the extended position with a damper.

A lock system, comprising:
- a lock, comprising:
- a retractable knob;
- a knob release mechanism for retaining the retractable knob in a retracted position, the knob release mechanism retaining the retractable knob in a retracted position until a motor of the knob release mechanism is actuated;
- a receiver configured to receive wireless transmissions, the receiver being in operable communication with the motor;
- a wireless key that communicates wirelessly with the receiver;
- and
- a microprocessor in operable communication with the motor and the receiver and wherein the knob release mechanism includes a damper that dampens movement of the retractable knob from the retracted position to an extended position, wherein the retractable knob is spring biased into the extended position.
