101 ADJUSTABLE SHIELD Abstract of the Disclosure An adjustable shield for a lamp, a camera, a viewing screen, or other interface, comprising at least three shield panels hinged to a rectangular base and a series of corner units, each composed of two corner panels, bridging the corner gaps between the shield panels; each corner panel is slidingly mounted on one end of a shield panel by guide means, in one instance a series of pin and slot guide connections that continuously maintain the corner panels and shield panels in pivotal alignment and that also define an outer limit for angular movement of each shield panel. For maximum angular range, the corner panels of each corner unit are hinge-connected. In an alternate construction, pivotal connections for the corner units are employed in the guide means. Friction pads on the shield panels, engaging the corner panels, may be used to increase the friction contact area.
