PCT No. PCT/FI95/00680 Sec. 371 Date Sep. 25, 1997 Sec. 102(e) Date Sep. 25, 1997 PCT Filed Nov. 8, 1995 PCT Pub. No. WO96/15023 PCT Pub. Date May 23, 1996A locking mechanism for large gates and hatches, such as visor, deck, bow and stem gates located on the side of a vessel. The locking mechanism includes an elongated hard-surface guide part having a hard-surface guide slot. The locking mechanism also includes one or more elongated hard-surface locking parts for securing within the guide slot. The elongated locking parts can include parts of unequal dimensions that simultaneously move in order to center themselves inside the hard-surface guide part. The locking part and the guide part each include two long sides that are beveled in a similar manner for forming a tight fit between the two parts when locked together. At least one locking pin passing through a respective slot in each of the parts tightly locks the two parts together to form a rigid construction in every direction. The construction can be unlocked and dismantled by undoing the locking pin or pins. Unlocking can also be facilitated by means of an opener pin.
