An adjustable support panel assembly for positioning a book, brochure, newspaper or the like in a predetermined orientation, wherein a support panel includes a pair of laterally adjustable frame members, with each frame member supporting a pair of relatively moveable clamping members. A first clamping member of each pair is fixedly attached to one of the frame members and a second clamping member is attached to a pusher shaft slidably received in a support rod also attached to the frame member, with a spring member biasing the second clamping member toward the first clamping member to fixedly clamp a book, brochure, newspaper or the like in a predetermined orientation therebetween.
The apparatus comprises a post having a floor-engaging base, an arm having its rear end pivotally connected to the top of said post for horizontal swinging movement, a connector pivoted to the front end of the arm for rotation about a vertical axis, said connector defining a rearwardly- upwardly-inclined plate-like element having upwardly-converging side edges which are also rearwardly converging thicknesswise of the plate-like element. A reading material support plate, having a bottom ledge, is provided at its back face with a pair of flat, elongated retainer elements which define between themselves a series of cavities with upwardly-converging side edges, which are also rearwardly converging thicknesswise for mating with and selectively receiving the plate-like element of the connector. It is a simple matter to insert the plate-like element in a selected cavity. The support plate is thus supported at a selected level and prevented from detachment from the connector. The apparatus is more particularly adapted to support a book or the like in reading position for a person seated in a chair.
