Publication number: 20190194995Abstract: A panel carriage hanger slidable along a track and having a body, rollers attached to the body to allow the body to travel along the track and a cylindrical bore in the body. The cylindrical bore has a lip including a plurality of castellations. The panel carriage hanger includes an anti-rotating sleeve inserted into the cylindrical bore, the castellations of the anti-rotating sleeve are mateable with the castellations of the cylindrical bore. The anti-rotating sleeve is movable from a first position in the bore where the anti-rotating sleeve can rotate in the bore and a second position in the bore where the castellations of the anti-rotating sleeve and the castellations of the cylindrical bore mate such that the anti-rotating sleeve cannot rotate.Type: ApplicationFiled: December 21, 2018Publication date: June 27, 2019Inventors: Duncan Duff McGregor, Nolan Couzyn, Bryce Alan Molloy, Peter Qin

Patent number: 6598910Abstract: A fastener for a closure. The fastener has a friction joint which couples first (10) and second (23) elements such that rotational movement there between can occur. The friction joint has a head fastener (28) and a sleeve (24) to which an end load is applied upon axial movement of the fastening taking place during coupling of the first and second elements (10, 23). This end load causes the sleeve (24) to collapse. The fastener has a wedge element (37) mounted for rectilinear movement in a direction substantially transversed to the axis of rotational movement of the friction joint. A drive arrangement (35) couples the wedge element (37) with the second element (23) such that rotation of the second element (23) is translated into the rectilinear movement of the wedge element (37). A removable handle (44) couples via fingers (49) to second element (23).Type: GrantFiled: January 17, 2001Date of Patent: July 29, 2003Assignee: Interlock Group LimitedInventors: Duncan Duff McGregor, Aaron Goldsbury
