Abstract

A restrictor for a window or a door comprises a first connector (10) adapted to be secured to a frame or sash of the window or door and a second connector (3) adapted to be secured to the other of the frame or sash. A cable or link (6) is secured at one end to the second connector (3) and has a spigot (11) secured to its other end. A lock (13) is housed within the first connector (10) and defines a channel (12) that receives the spigot (11). The lock (13) comprises a movable locking member (19) that in a first position engages the spigot (11) to lock the spigot (11) within the channel (12) and that is movable into a second position to unlock the spigot (11) allowing its withdrawal from the channel (12). The movable locking member (19) is biased into its first position and moved into its second position against the force of the bias (26) by the spigot (11) on its insertion into the channel (12). Movement of the spigot (11) further into the channel (12) releases the locking member (19) to return to its first position under the influence of its bias (26) wherein it engages the spigot (11) to secure it in the channel (12) of the lock (13). Hence, the restrictor of the invention may always be deployed to restrict window or door opening as no key is required to lock the cable to the first connector via the spigot.

Abstract

A lock cylinder, in particular a euro-lock cylinder, is provided for a locking mechanism for doors and other similar closures. The lock cylinder comprising a casing (1) defining a longitudinal axis with a rotatably mounted cam (4) comprising a radially projecting lever (5) that is adapted to actuate the locking mechanism on rotation of the cam (4). First and second cores (6, 7) are rotatably mounted within the casing (1) on either side of the cam (4) respectively. A clutch arrangement is located between the first and second cores (6, 7) and comprises first and second clutch members (16, 17) for placing either the first or the second core (6, 7) into engagement with the cam (4) by movement along a longitudinal axis of the lock cylinder against the force of a biasing means (18, 19). First and second spring-loaded engagement mechanisms (23, 24, 25; 32, 33, 34) are acted on respectively by the first and second clutch members (16, 17) and are adapted to releasably connect either the first or the second clutch member (16, 17) and thereby the first or the second core (6, 7) to the cam dependent on which of said first and second cores (6, 7) is engaged by a user The connection of one of the first and second engagement mechanisms (23, 24, 25; 32, 33, 34) to the cam (4) releases the other of the first and second engagement mechanisms (23, 24, 25; 32, 33, 34) from such connection. The second clutch member (17) is adapted to move the second engagement mechanism (23, 24, 25; 32, 33, 34) into a position wherein it locks into engagement with the cam (4) if the casing (1) is broken and the first core (6) removed.

Abstract

A key-operated pin tumbler lock comprises a shell (20) in which is rotatably disposed a plug (21) that defines a keyway (23) and a plurality of bores (24). The bores communicate with the keyway (23) through the plug (21) and in a locked position of the lock communicate with corresponding bores formed in the shell (21). A plurality of spring-loaded pin stacks (25) are located within the bores (24) and are moveable within the bores (24) against the spring-loading (31) by a key (40) inserted in the keyway (23) into a position wherein the plug (21) can be rotated relative to the shell (20). A stop means (32) is provided in one (26) of the bores and is adapted to engage the pin stack (27) which is located therein such that a key pin (34) of the stack (27) is prevented from penetrating into the plug (21) to a level reached by key pins (29) of the other pin stacks (25). Such a lock is significantly less susceptible of being opened by a lock bumping technique than a conventional key- operated pin tumbler lock. Preferably, the plurality of spring-loaded pin stacks (25) each have a height randomly selected from a bitting range, and a second additional pin stack (53) is provided in the lock that has a height greater than the greatest height of said bitting range. A key adapted to lock and to unlock said key-operated pin tumbler lock is also provided.
