Abstract: A mount that secures a projector to a ceiling is disclosed. The mount includes an upper element which is attached to the ceiling, and a lower element which is attached to the projector. The two elements are adapted to slidably engage and disengage for quick mounting without having to detach the upper element from the ceiling and the lower element from the projector. The mount may include a spring-biased latch which locks the two elements together to prevent accidental disengagement. The latch may include a safety lock feature which prevents inadvertent actuation of the latch and subsequent disengagement of the elements.

Abstract: A security mounting assembly for an electrical appliance, such as a color television monitor, includes a mounting ring which may be attached to a flat mounting surface by a series of fasteners. The mounting ring includes glide members disposed thereon radially outwardly of the fasteners and the mounting ring is captured between two flanges attached to a flat support tray. The support tray is attached to the television with fasteners and swivels in place upon the attachment ring.
