Patent number: 4296946Abstract: A book support consists of a book supporting plate and a back plate hinged to the top of the front plate and extending outwardly and downwardly when extended, to form an inverted V when viewed in side elevation. A cord is secured by each end thereof to the sides of the front plate and extend through guide apertures at the sides of the back plate to be hooked over one of several projections on the back plate to adjust the angle between the plates. A pair of slide members extend one from each side of the front plate to adjust to the width of the book and a further cord is detachably secured by one end thereof to one of said slides, passes across the open book and detachably hooks onto the other of said slides to hold the pages relatively flat. This cord is disengaged from the other slide when a page is to be turned and rehooked afterwards to hold the pages open and relatively flat. The holder can be folded relatively flat for storage, without removing the book from the holder.Type: GrantFiled: August 27, 1979Date of Patent: October 27, 1981Inventors: Frank J. Larre, Jeannine G.

Patent number: 4171116Abstract: An adjustable and collapsible easel having a plurality inner and outer telescoping leg sections. The upper ends of the outer leg sections are connected to a common connecting member for articulated movement between fully spread and fully folded positions. The outer ends of a plurality of foldable brace members are connected to respective ones of the outer leg sections and the inner ends of the brace members are connected to a common fitting. The brace members reinforce and hold the legs in an operative, spread position. Cam surfaces on the outer ends of the brace members engage and prevent telescoping movement of the inner leg sections relative to the outer leg sections when the legs are in either fully spread or fully folded positions. The length of the legs and locking of the same in their operative, fully spread position is effected by depressing the fitting which interconnects the inner ends of the brace members.Type: GrantFiled: March 3, 1977Date of Patent: October 16, 1979Assignee: Beckley-Cardy CompanyInventors: George E.

Patent number: 4042203Abstract: A folding artist's easel, particularly suited for a classroom or teaching environment, utilizes square steel tubing to form a rigid triangular base, a supporting column, and a telescopic brace, with pivotal connections therebetween. The pivotal connections are substantially free of side play and along with connection of the supporting column to a mid-point of one side of the triangular base and connection of the brace to an apex opposite this side, superior stability is provided as well as a minimum required floor space to the rear of the easel, a feature which is particularly desirable in a classroom. A workpiece, such as a drawing board or canvas stretched on a frame, is securely and gently clamped to the easel by means of individually adjustable upper and lower steel cross-members which permit adjustment in the elevation of the workpiece as well as clamping a workpiece of great height. The top of the column is adapted to receive an extension for further increasing the effective height of the easel.Type: GrantFiled: October 7, 1975Date of Patent: August 16, 1977Inventor: Verona D.
