Abstract (en)
A cylindrical lock has a barrel (1) turnable in a cylinder (2), the barrel (1) carrying 5 longitudinally orientated rods (3) in slotted holes (41), each rod (3) having a stop (4) at a selectable position to establish a combination and a tab (5) at a further selectable position to establish a further combination, the rods (3) slideable in the slotted holes (41) and spring loaded (7), the stops (4) entering longitudinally arranged grooves (10) in the inner surface of the cylinder (2) to normally lock the barrel (1) irrotationally in the cylinder (2) but moveable on application of a key (16) with correct combination to bring the stops (4) in line with a single circumferentially arranged groove (11) in the inner surface of the cylinder (2) to free the barrel (1) and allow its rotation in the cylinder (2) in an unlocked state. A front plate (12) with a slotted hole (13) retains the key (16) in the lock until it is turned to the position in which it was initially inserted.
