Safety lock which prevents unauthorised and forced openings - has bolt with depression for additional disc actuated by coded key

摘要

The safety lock has a housing holding locking bolt and its locking mechanism. This lock mechanism prevents undesirable nonforcing or forced opening attemps by suppression of clocking noises and by using robust components. The locking bolt (5) has on its upper side a machined depression (6). The latter engages with a locking disc (3) on using a locking pin (2). A space is formed between the locking bolt head and housing. The locking disc is pushed for blocking purposes into the depression. The disc holds the rotating locking closing bolt (4) in locking position. The locking bolt head is rotated by a code key into the space between the locking bolt head and housing.
