Claim:
A security apparatus comprising: at least one door, which has a first retracted position and a second extended position, a closing mechanism comprising: a door outer slide tube, which is connected to the at least one door, a door inner slide tube, the door outer slide tube slides along the door inner slide tube, the at least one door being stationary relative to the door outer slide tube, a door closure cable, at least one pulley, and an elasticized cord, which is able to store a potential energy; the door closure cable is connected to the door outer slide tube and runs through the at least one pulley and is further connected to the elasticized cord; a release apparatus comprising: a release lever, a release cable, and a door keeper, wherein the door keeper is rotatably movable between a locking position and a release position, the release lever is connected to a first end of the release cable; the door keeper is connected to a second end of the release cable; the release lever having a first position and a second position; in the first position, the release lever, which is connected by the release cable to the door keeper, positions the door keeper against the outer slide tube in the locking position to block the door outer slide tube from moving along the inner slide tube, in the second position, the release lever is moved such that the door keeper is moved away from the outer slide tube to the release position and no longer blocks the door outer slide tube from moving along the door inner slide tube and allows the release of the potential energy of the elasticized cord to move the at least one door to the second extended position.
