Abstract: A combination of a door, a door-jamb and a magneto-mechanical-latching-assembly is provided. The door is mounted to close an opening adjacent to the door-jamb. The latching-assembly operates to secure the door in a closed position. The latching-assembly includes a latch-component and an actuator-component. The latch-component is associated with one of the door and door-jamb. The latch-component includes a latch that includes a latch-magnet having a latch-magnet-polar-axis. The latch is mounted relative to the latch-component to reciprocate along a substantially horizontal and linear latching-path between an extended-latching-position and a retracted-non-latching-position. The actuator-component is associated with the other of the door and door-jamb. The actuator-component includes an actuator that includes an actuator-magnet having an actuator-magnet-polar-axis.

Abstract: A spring-biased hinged assembly (10) including a spool (30) associated with a first hinged member (20) a spring (70) associated with a second hinged member (60) and a tensile member (100) extending from the spool (30) to the spring (70).

Abstract: The present invention relates to engagemnent devices and coupling members for forming a structural frame work for hollow tubes. One form of engagement device comprises a hollow sleeve (1) through which a tube (31) may be passed. The hollow sleeve has a deformable flared portion (2). A further hollow sleeve member (12) is immovable on the outside of the first sleeve and has a surface (13) arranged to co-operate the flared portion to cause it to deform to grip the tube (31). A further engagement device comprises a hollow sleeve portion (100) which is distendable to grip a tube mounted on its surface. A trustoconical wedge (101) is movable within the hollow sleeve potion (100) to cause to distend. A number of engagement devices may be connected together to form coupling members for connecting tubes to form a structural frame work.

Abstract: The hinge comprises a first hinge member (11) and a second hinge member (12). The first hinge member comprises a cylindrical housing (16) having first and second open ends (17 and 18 respectively). The cylindrical housing (16) is located between flange members (26 and 27) of the second hinge member (12). A torsion spring (20) is provided inside the cylindrical housing (16) and one end (21) fits into a recess (22) at end (18) of the cylindrical housing (16) and the other end fits into a recess (36) in a coupling element (30) which is located at the other end (17) of the cylindrical housing (16). The coupling element (30) has a hexagonal engagement surface (39) which engages a matching engagement surface in flange (27).
