摘要：A vertically adjustable fixture, such as a ceiling hook, comprises a base memberadapted to be secured to an overhead surface, e.g. a ceiling, a beaded cable retractablein 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. Anextension/retraction mechanism provided in the base member includes a fixed axle and areel rotatable around the axle, with a spring force existing therebetween, the cable beingpartly wound around the reel. The elevation of the hook is maintained by one of thebeads of the cable firmly lodging, in a locked position thereof, in a recess defined at thebottom of the cover. Manipulation of the cable to dislodge the bead from the recessunlocks the cable, thereby allowing the elevation of the hook to be adjusted.
