Abstract
Abstract A bracket to support instruments, lamps and other equipment is detachably connected to the lipped channel used in hospital wall and cart constructions. The bracket has a hollow housing having a hole at one end to receive a rod on which the instrument is mounted with a set screw to hold the rod in place. The opposite end of the housing has a first projecting lug to fit inside one lip of the channel. A dog member fits inside the housing and has a projecting second lug to fit inside the other lip of the channel. An adjustment screw fits inside the housing and threadedly engages the dog to move the second lug toward and away from the first lug. When the lugs are close together, they may be inserted between the channel lips at any point along the length of the channel. By turning the adjustment screw, the second lug may be drawn away from the first lug to lock against the channel lips, securing the bracket in position.
