Claims11
A combination lock, comprising:
- a housing having a lock port configured for removably receiving therein a shank;
- a locking bar received within the housing and having a shank port, said locking bar being configured for displacing at least between:
- an open position in which the shank port is aligned with the lock port to allow a locking portion of said shank to displace into said housing through both ports, and
- a securing position in which said shank port is misaligned with the lock port to prevent the locking portion of the shank from displacing outside said housing via the shank port;
- a combination mechanism associated with said locking bar and configured for switching between at least:
- an unlocked position in which said locking bar is free to displace from its securing position to its open position, and
- a locked position in which said locking bar is arrested;
- and
- a securing arrangement constituted by an arresting member of the locking bar, an arresting portion of the housing, and a biasing mechanism, wherein:
- said arresting member of the locking bar is configured for interlocking engagement with the arresting portion of the housing,
- said biasing mechanism is configured for urging said locking bar into the interlocking engagement with the arresting portion of the housing, and
- said securing arrangement being configured, when the locking portion of the shank is dislodged from the lock port, to prevent displacement of said locking bar from its open position.

A locking bar for a combination lock, said locking bar comprising:
- a shank port for axially receiving therein a locking portion of a shank;
- at least one locking surface configured for operative engagement with the locking portion of the shank during its axial displacement into said shank port, for entailing displacement of said locking bar in a first lateral direction towards a securing position thereof;
- at least one unlocking surface configured for operative engagement with the locking portion of the shank during its opposite axial displacement outside the shank port, for entailing displacement of said locking bar in an opposite lateral direction towards an open position thereof;
- and
- a tamper proof arrangement by which the at least one unlocking surface is configured for collapsing under the application of a predetermined load thereto, disabling the operative engagement with the locking portion of the shank.
