Lock with movable knob

A lock, comprising:

• a retractable knob;
• a knob release mechanism for retaining the retractable knob in a retracted position, the knob release mechanism including a damper with a gear that is slidably received within a set of grooves located in the retractable knob, the gear prevents rotation of the retractable knob unless the retractable knob is in an extended position;
• and
• 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 has a hook portion that is received in a cavity of the retractable knob when the retractable knob is in the retracted position and the secondary arm is in the first position.

A lock, comprising:

• a retractable knob;
• a knob release mechanism for retaining the retractable knob in a retracted position, the knob release mechanism including a damper with a gear that is slidably received within a set of grooves located in the retractable knob, the gear prevents rotation of the retractable knob unless the retractable knob is in an extended position;
• and
• a primary arm and a secondary arm, wherein the secondary arm is configured to retain the retractable knob in the retracted position and the primary arm has a protrusion configured to engage a slot of the secondary 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;
• and
• damping movement of the retractable knob from the retracted position to the extended position with a damper that includes a gear that is slidably received within a set of grooves located in the retractable knob, wherein the set of grooves include a first set of grooves and a second set of grooves, the second set of grooves having a greater length than the first set of grooves, and the first set of grooves are closer to a forward surface of the retractable knob than the second set of grooves.

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 including a damper with a gear that is slidably received within a set of grooves located in the retractable knob, the gear prevents rotation of the retractable knob unless the retractable knob is in an extended position, wherein the set of grooves includes a first set of grooves and a second set of grooves, the second set of grooves having a greater length than the first set of grooves, and the first set of grooves are closer to a forward surface of the retractable knob than the second set of grooves;
• a receiver configured to receive wireless transmissions and wherein the receiver is in operable communication with a motor for actuating the knob release mechanism so that the retractable knob can be moved into the extended position;
• and
• a wireless key that communicates wirelessly with the receiver.
