  • Patent number: 9890562
    Abstract: This invention relates to a locking arrangement 10 which includes a body 12 and a locking member 14 which is displaceable relative to the body 12. The locking member 14 defines at least one striker element engagement formation 18.1, 18.2 which is configured to engage a striker element 100 for part of its displacement relative to the locking arrangement 10 along a predetermined displacement path. The locking member 14 is displaceable between first and second spaced apart positions in each of which the engagement formation 18.1, 18.2 is positioned such that a said striker element 100 is releasably engageable therewith and between which a said striker element 100 is in engagement with the engagement formation 18.1, 18.2. The locking arrangement 10 further includes a securing mechanism 16 which is configured to secure the locking member 14 releasably in at least one of the first and second spaced apart positions.

  • Patent number: 8316674
    Abstract: A lock (10) which includes a body and an actuator (36) which is pivotally displaceable between a rest position and a displaced position. The lock further includes a first member (64) which is longitudinally displaceable by the actuator (36) and a second 5 member (66) which is longitudinally in register with the first member (64) and longitudinally displaceable relative to the body and the first member (64). The lock includes bias means (90) biasing the first and second members (64, 66) away from one another. The lock further includes retaining means (98) which is displaceable from a locked position, in which it inhibits displacement of the second member (66) and a 10 released position in which it permits displacement of the second member (66).
