ABSTRACT:
A multishaft combination lock includes a lock body, an alignment sleeve, and a detachable pin. The alignment sleeve has a hole and is rotatably coupled to the lock body to provide access into the lock body. The alignment sleeve has an angled cutout at a first end, with the alignment of the cutout being adjusted by rotating the alignment sleeve. The detachable pin has a floating bushing that can be misaligned with the principle axis of the detachable pin. To lock the multishaft combination lock, the lock body is fitted to the detachable pin through the hole of the alignment sleeve with the floating bushing misaligned with the angled cutout. When the detachable pin is fully inserted into the lock body, the floating bushing is positioned beyond the end of the alignment sleeve within the lock body and becomes misaligned or offset with the alignment sleeve. To unlock the lock, the alignment sleeve is rotated so that the angled cutout is aligned with the floating bushing of the detachable pin. When the detachable pin is withdrawn from the lock body, the cutout of the alignment sleeve causes the floating bushing to become aligned with the alignment sleeve, thereby allowing the detachable pin to be removed.
