Abstract
A lock includes a stationary key mass having a key mass bore and a keyway, and a movable spring mass having a spring mass bore. A spring mass pin is mounted in the spring mass bore, and a key mass pin is mounted in the key mass bore for reciprocation between a locked position immobilizing the spring mass and an unlocked position unconstraining motion. The unlocked position is a function of the presence of a matching key in the keyway. Multiple key mass and spring mass pins can be used, and some can have stepped configurations. Corresponding single-bladed or multi-bladed keys, or multiple keys, can be used. The keys can be straight or curved or flexible to match curved keyways.
Claims78
A lock comprising:
- a lock body;
- a key mass rigidly coupled to the lock body, the key mass including a first key mass bore and a keyway in communication with the first key mass bore;
- a spring mass movable relative to the key mass, the spring mass including a first spring mass bore;
- a stopper coupled to the spring mass and movable thereby between a locked position and an unlocked position of the lock;
- a first key mass pin mounted for reciprocation in the first key mass bore;
- and
- a first spring mass pin mounted for reciprocation in the first spring mass bore,
- wherein the keyway is configured to receive a matching key for motivating the first key mass pin between first and second positions corresponding respectively to the locked and unlocked positions of the lock, at least one of the first spring mass pin or first key mass pin interfering with the relative motion in the first position and not interfering with the relative motion in the second position.

A lock comprising:
- a stationary key mass including a first key mass bore and a keyway in communication with the first key mass bore;
- a movable spring mass including a first spring mass bore;
- a first spring mass pin mounted for reciprocation in the first spring mass bore;
- a first key mass pin mounted for reciprocation in the first key mass bore between a locked position in which the spring mass is immobilized and an unlocked position in which spring mass motion is unconstrained in at least one direction, wherein the unlocked position is a function of the presence of a matching key in the keyway.

A lock comprising:
- a key mass having a keyway for receiving a matching key;
- and
- a spring mass that is movable from a first position to a second position when the matching key is disposed in the keyway and when an unlocking force is applied to the lock, the first and second positions corresponding to a locked state and an unlocked state of the lock, respectively,
- wherein the unlocking force is applied along a force path that is independent of the key.
