Abstract: A window fastener including: a base configured for connection to a window sash; a handle carrying a latching tongue, pivotally connected to the base between a latched position and an unlatched position; and an interface between the base and the handle, wherein the interface causes the latching tongue to move axially closer to the base when the handle pivots from the unlatched position to the latched position; and wherein the interface causes the latching tongue to move axially away from the base when the handle pivots from the latched position to the unlatched position.

Abstract: A lock assembly comprising: a hand-operable member configured to move laterally relative to a fore-end of the lock assembly; wherein lateral movement of the hand-operable member causes the lock assembly to move between a locked mode and an unlocked mode. A lock assembly comprising: a latch, the latch configured to move rotationally relative to the lock assembly; and a hand-operable member configured to move laterally relative to a fore-end of the lock assembly; wherein the hand-operable member is coupled to the latch such that lateral movement of the hand-operable member drives rotational movement of the latch. Methods of installing a lock assembly, comprising setting a hub of a lock assembly to one of a first unlocked position, a first locked position, a second unlocked position, a second locked position, or a deadlocked position, and installing a cylinder lock for engagement with the hub.

Abstract: A panel carriage hanger designed to travel slidable along a track, the panel carriage hanger having a cylindrical bore in a body, the bore having a lip substantially at a first end, the lip having a plurality of castellations. An anti-rotating sleeve having a plurality of castellations is located in the bore, and a biasing mechanism provides a substantially downwards force to the anti-rotating sleeve to mate the castellations. The anti-rotating sleeve movable substantially upwards from a first position in the bore where the castellations of the anti-rotating sleeve and the castellations of the bore mate such that the anti-rotating sleeve cannot rotate into a second position in the bore where the anti-rotating sleeve can rotate. A rod passing through and keyed to the anti-rotating sleeve such that the rod and the anti-rotating sleeve can rotate together, or both cannot rotate.

Abstract: A closure mechanism is described, the closure mechanism comprising: a base; a carriage movable along the base; a catching mechanism movable along the carriage; a first resilient mechanism connecting the base and the catching mechanism; and a second resilient mechanism connecting the carriage and the catching mechanism.

Abstract: A latch includes a protrusion that extends from a latch body. The protrusion moves from a fully extended position to a partially extended position when the door or window to which the latch is mounted is moved to a closed position. This movement of the protrusion disengages an anti-slam mechanism, allowing movement of a latch mechanism. Further, the partially extended protrusion engages in an anti-lift recess in the strike. Alternatively, the protrusion may extend from the strike and engage with an anti-lift recess in the latch body.

Abstract: A roller assembly comprising: a roller housing comprising first and second side walls and first and second end walls forming an enclosure; a carriage assembly comprising a carriage body and at least two carriage wheels rotatably attached to the carriage body, wherein the carriage assembly is located within the enclosure such that the at least two carriage wheels are arranged to protrude from the bottom of the enclosure during use; wherein the carriage body comprises a support portion and at least two concentric pivot points arranged to locate within slanted passages formed in the first and second side walls to allow the carriage body to rotatably pivot about the pivot points; an intermediate adjusting mechanism slidably engaged with the roller housing and arranged to move lengthwise within the enclosure, the intermediate adjusting mechanism comprising a first engagement surface located on an extending member, wherein the extending member extends in a direction substantially perpendicular to the lengthwise mov

Abstract: The invention relates to an adjustable strike having a striker plate, an end cap removably attached to an end of the striker plate, and the end cap having a first protrusion and a second protrusion, each for attaching the end cap with a door frame. The end cap also has a tab for removably attaching the striker plate with the end cap. The invention also relates to a method of providing the adjustable strike.

Abstract: A latch which is suitable for latching a window in a closed and sealed position. The latch has latch furniture 10 adapted to fit into a window section S with minimal protrusion from the section. The furniture includes a sealing lever handle 17 and a latch release handle 16 located in a recess 15 in the latch furniture. The latch further includes a latch mechanism 11 adapted to engage with the latch furniture 10. The latch mechanism 11 has one or more latch bolts 65 operable by the latch release handle 16 and a latch pin 41 engageable with a striker assembly which is mounted to a section of a window frame. The latch pin 41 is coupled to the sealing lever 17 whereby operation of the sealing lever 17 moves the window section S into a sealing position relative to the striker assembly.
