Abstract
A rotary lock has a shank with a latch at each end mounted to be rotated in a housing. The latch has three positions with a basic position with both latches in a locking position being disposed between the other two positions in which one latch is locked and the other latch is unlocked. The lock includes a handle connected to the shank to move the lock from the basis position to the other two positions against a force of a single spring which biases the latches and shank back toward the basis position.
Claims24
A rotary lock comprising a locking pin mounted for rotation in a housing on a longitudinal axis of the pin, said pin having a shank with a transverse latch at each end and being connected to a hand lever, the rotary lock being adapted to be brought basically into three positions relatively to the corner fittings of a container for the purpose of releasably connecting two containers one upon the other, said three positions being the locking position of one transverse latch and the unlocking of the other latch, unlocking position of the one transverse latch and the locking of the other transverse latch and a locking position of both transverse latches, the improvement comprising only one spring means being provided and being connected between the hand lever and the locking pin, and the housing having detent means to lock the hand lever and the locking pin in each of the three positions of the transverse latches, the locking position of both transverse latches being a basic position of the rotary lock and any rotation of the locking pin out of the basic position, irrespectively of whether to the left or right, is against the force of the spring means which stores energy for subsequent return to the basic position for automatic locking.
