Abstract:
1. Anchorage device, for use in anchoring objects to a track having a top channel opening defined between opposed overhanging channel lips, the anchorage device comprising: an elongate body having a front end, a rear end, an intermediate portion and an underside; plural track-engaging formations attached relative to and distributed along the underside of the body, for insertion into the channel opening of the track in use, said track-engaging formations including longitudinally-slidable protrusions and one or more non-slidable protrusions and operable to provide a secured condition in which the longitudinally-slidable protrusions are captive beneath the track lips and the anchorage device is held against being pulled out of the track, one or more of said track-engaging formations being movable, in an actuating operation of the device, relative to one or more other said track-engaging formations and/or relative to the elongate body; and an actuating mechanism for driving a said relative movement of one or more of said relatively movable track-engaging formations and an actuating member for driving the actuating mechanism, said actuating member being provided at the rear end of the body, the actuating mechanism comprising an elongate drive element extending longitudinally of the body and having a longitudinal axis, operatively connected at a proximal end thereof to the actuating member, and operatively connected at a distal part thereof to a said relatively movable track-engaging formation spaced along the body at a position longitudinally remote from said actuating member, whereby in said actuating operation, movement of the actuating member displaces the elongate drive element longitudinally to operate a said relative movement of said remote track-engaging formation in which one or more said longitudinally-slidable protrusions is driven longitudinally relative to one or more said non-slidable protrusions.
