<p>A multi-point lock comprises a main lock unit 1 and upper and lower end units 2 and 3. Each end unit comprises a hook bolt 6 which is extended and retracted in the opposite pivotal sense to the other. Within each end unit there is a reciprocable rack 16 for pivoting the respective bolt 6 and a detent plate 24 for blocking forced retraction of the bolt when extended. In order to retract the bolt 6 the detent plate 24 is released by a pivoted link 19 operated by a drive bar 7 from the main unit 1 and through which the rack 16 is also operated. <IMAGE> <IMAGE></p> |
