Abstract
A lock joins two bodies together. The first body has a first hole and the second body has a second hole, and the lock includes a rail on the first body adjacent to the first hole, two spaced-apart cradles movable on the rail, a spring between and attached to the two cradles that urges the two cradles toward each other, a plunger that moves perpendicular to a longitudinal axis of the spring through the first hole, where the plunger has a locking end that moves into the second hole to join the bodies together. The lock has two levels that are each hinged to a different one of the cradles and to the plunger and that cause the locking end of the plunger to retreat from the second hole to unlock the bodies when the cradles move toward each other.
Claims20
A plunger lock comprising:
- a rail and two spaced-apart cradles that are each movable on said rail;
- a longitudinally extended coil spring that is between and attached to said two cradles;
- a plunger that is between said two cradles and that is movable perpendicular to a longitudinal axis of said coil spring between a lock position and an unlock position, said plunger being in the lock position when a locking end of said plunger is spaced a first distance from said rail and in the unlock position when said locking end is closer to said rail than the first distance;
- and
- two levers that are each hinged to a different one of said two cradles and that are each hinged to said plunger and that cause said plunger to retreat from the lock position to the unlock position when said two cradles move toward each other.
A plunger lock comprising:
- a rail and two spaced-apart cradles that are each separately movable on a first surface of said rail;
- a tensioning device that is between and attached to said two cradles and that urges said two cradles toward each other;
- a plunger that is between said two cradles and that is movable perpendicular to said rail between a lock position and an unlock position, said plunger being in the lock position when a locking end of said plunger is nearer to a second surface of said rail that is opposite said first surface than to said first surface and when said locking end is spaced a first distance from said second surface, and said plunger is in the unlock position when said locking end is closer to said second surface than the first distance;
- and
- two levers that are each hinged to a different one of said two cradles and that are each hinged to said plunger and that cause said plunger to retreat from the lock position to the unlock position when said two cradles move toward each other.
A combination of a first body, a second body, and a lock that joins said first and second bodies to each other,
- said first body having a first hole entirely through said first body and said second body having a second hole at least partially through said second body, said first and second holes being in registration when said first and second bodies are joined by said lock;
- and
- said lock comprising,
- a rail that is on a first surface of said first body opposite said second body and that is adjacent to said first hole,
- two spaced-apart cradles that are each separately movable on said rail,
- a tensioning device that is between and attached to said two cradles and that urges said two cradles toward each other,
- a plunger that is between said two cradles and that extends from said first surface through said first hole, said plunger having a locking end that is selectively movable into said second hole to join said first and second bodies, and
- two levers that are each hinged to a different one of said two cradles and that are each hinged to said plunger and that cause said locking end of said plunger to retreat from said second hole when said two cradles move toward each other.
