Abstract:
A structure including a rigid infill supported by an outer frame comprising outer frame members extending between spaced comer joints, at least one of said outer frame members connected by a telescopic joint associated with a said corner joint, said telescopic joint adjustable to change the effective length of the corresponding said outer frame member. A structure including a rigid infill supported by an outer frame comprising outer frame members extending between spaced comer joints wherein at least one corner joint is adaptable to change the included angle defining the relative disposition of the outer frame members participating in the comer joint, said corner joint including a fastener, a cupped member and a protruding shoulder wherein tightening of the fastener urges the cupped member and protruding shoulder towards each other to form a frictional joint able to resist relative angular displacement between the outer frame members participating in the corner joint

A lock for a displaceable wing including a casing and slide means including a driven slide and a counteracting slave slide supported by the casing each including a leading end displaceble between relatively most spaced and relatively least spaced configurations, remote engaging means Including a first and/or second remote engaging member each operably connected by a respective drive member relative to a respective leading end for displacement between an operative and an inoperative configuration, operating means including a hand operable handle by which to actuate the slide means, safd handle having passage through an aperture in a side of the wing to be accessible from a side of the wing, the lock characterized by the handle being substantially at one end of its loci of movement when each remote engaging member is in its operative configuration.
Abstract:
An assembly (3) including a displaceable retainer, a base (5) and a handle having a substantially cylindrical shank (6) that extends into an aperture (7) of the base (5), the shank (6) having an axial recess (16) and a peripheral groove (10), the assembly (3) characterized by a first configuration where the retainer (11) extends into the axial recess but not into the peripheral groove (10), and a second configuration where the retainer (11) extends into the peripheral groove (10), the second configuration further characterized by the shank (6) being restrained by the retainer (11) relative to the base (5).
Abstract:
A pin cylinder housing comprising a longitudinally extended member having an axially extended bore and multiple orthogonal substantially cylindrical pin recesses each extending from the bore to an opening in a side surface, and a plug by which to terminate pin recesses, said plug occupying a plug recess within the housing comprising the sum of a slotted recess having a depth and extending between spaced pin recesses, said plug comprising a member having side cap portions defined in part by an arcular peripheral cap edge and an outer surface sharing the same form as the side surface, said arcular peripheral cap edge being defined in part by a radius substantially the same as the radius that defines the pin recesses.
Abstract:
A security screen door (1) for vehicles comprises a frame (2) forming an opening, at least one sliding section (10, 12) within the frame and a quick action lever (21) on an inside of the door for locking and unlocking the door via a first lock (20). The sliding section comprises a second lock (14) for securing the sliding section in a closed position, the second lock being unlocked from an outside using a key to allow the sliding section to be moved from a closed position to an open position to allow access from the outside to the quick action lever.
Abstract:
A structure comprising infilling material bounded by a peripheral frame that is adaptable to change the shape of the structure said structure including a substantially continuous peripheral recess occupied by an outer frame that includes outer frame members and corner covers which together extend from the channel to have a substantially uninterrupted form.
Abstract:
An adjustable engagable member of a striker box mounted on a door frame member, for engagement with a conventional security locking bolt mounted on a hinged door leaf, whereby adjustment can be made in a perpendicular direction to the door frame member on which the striker box is mounted in order to change the clearance between the hinged door leaf and the engagable member.
Abstract:
A lock mountable to a displaceable wing (1) including a casing (5) and operating means including at least one hand operable unlatching lever (109) operable in an unlatching direction to cause a corresponding unlatching cam (101) to displace in an unlatching direction, an engaging member (7) supported by the casing and displaceable between a fully displaced disposition and a fully retracted disposition, the unlatching cam being operably connected to the engaging member by an angularly displaceable unlatching rocker (87) supported at a pivotal joint (333) disposed between the engaging member and the unlatching cam, the unlatching rocker having a first arm (88) operably associated with an unlatching arm of the unlatching cam and a substantially opposed second arm (90) operably associated with the engaging member, the unlatching cam being displaceable in an unlatching direction to cause unlatching arm to displace the first arm of the rocker to displace the second arm in the opposite direction to thereby cause the engaging member be displaced towards the fully retracted disposition. A lock as described above and including an angularly displaceable driver member (158) having an undisplaced disposition and being connectable to at least one remote engaging member to actuate the remote engaging member, said driver member being displaceable towards the undisplaced disposition by displacement of an unlatching cam in an unlatching direction, said driver member being displaceable from the undisplaced disposition by displacement of an unlatching cam in the opposite direction.
Abstract:
A member including a first portion assembled to a second portion, said first portion (1) having at least one sloping surface (12) disposed relative to an adjacent fixing shoulder (13), said second portion (7) having a fixing pin (6) for each fixing shoulder disposed relative to the sloping surface (12), said fixing pin in the assembled member overlapping both the sloping surface and the fixing shoulder (13) to restrain the portions against separation.
