Abstract: A vertically adjustable fixture, such as a ceiling hook, comprises a base member adapted to be secured to an overhead surface, e.g. a ceiling, a beaded cable retractable in and extendable out of the base member, and a hook at a lower end of the cable for connection to an article such that the article may be suspended from the ceiling. An extension/retraction mechanism provided in the base member includes a fixed axle and a reel rotatable around the axle, with a spring force existing therebetween, the cable being partly wound around the reel. The elevation of the hook is maintained by one of the beads of the cable firmly lodging, in a locked position thereof, in a recess defined at the bottom of the cover. Manipulation of the cable to dislodge the bead from the recess unlocks the cable, thereby allowing the elevation of the hook to be adjusted.

Abstract: A ceiling hook (H) comprises a fastener (F) for anchoring in a support structure, and a locking ring in the form of an anti-rotation washer (W). The washer (W) includes anchoring teeth (34) for stationarily mounting the washer (W) to the ceiling. The hook member (12) and the washer (W) comprise co-operating locking ratchet elements (22, 28) for locking the fastener (F) to the washer (W) and thus preventing the fastener (F) from loosening from the ceiling. The washer (W) defines at a central opening (30) thereof at least one notch (32) with the fastener (F) defining at least one tab with (26), the notch (32) being slidable through the tab (26) for mounting the washer (W) to the fastener (F) and then allowing it to rotate between the tab (26) and the book member (12), whereby the washer (W) is prevented from being removed from the fastener (F) unless the tab (26) and notch (32) are aligned.
