ABSTRACT:
A locking method and device applicable to lock a linearly retractable device includes a locking plate in a first direction and a second direction perpendicular to each other. In the first direction, the locking plate is movable in a release position and a safety position. In the second element, the locking plate is movable in a latched and an unlatched position. When the locking plate is in the safety position, it is unmovable from the latched position to the unlatched position so as to prevent any unintentional force to release the lock.
