Patent ID: 6910357

Claim:
A lock, comprising: a lock housing ( 3 ; 40 ); a bolt or catch ( 20 ; 50 ) mounted in said housing for movement between an inwardly withdrawn position and an outwardly extended position and which includes a weakened region ( 36 ; 68 ); a blocking element ( 5 ; 42 ) comprising a lock post of the lock housing; a moveably mounted interlocking device ( 12 , 14 , 16 ; 58 ); and a bolt-mounted abutment element ( 34 ; 66 ) adapted to coact with the interlocking device in an interlocking position so that when a part of the bolt exposed outside the lock housing, in said outwardly extended position, is subjected to an external force that strives to return the bolt to its inwardly withdrawn position and that exceeds a generally predetermined force, the bolt will deform in said weakened region upon stress in the form of a force caused by the co-action between said abutment element and said interlocking device, wherein the deformed bolt has a shape such that said blocking element blocks movement of the bolt from said outwardly extended position to said inwardly withdrawn position, wherein the bolt ( 20 ; 50 ) is comprised of at least three lamella ( 24 , 26 , 28 ; 52 , 54 , 56 ) and the abutment element ( 34 ; 66 ) and the weakened region ( 36 ; 68 ) are arranged on at least one intermediate lamella ( 24 ; 52 ).
