  • Patent number: 7823857
    Abstract: A collapsible easel for holding items to be displayed, the easel having a top assembly and a base assembly. The base assembly includes two front legs and a rear leg, each leg pivotally mounted to the top assembly with cushion members forcing part of the top assembly to provide a slight restriction against pivoted movement of the two front legs. A V-shaped spring assembly is pivotally mounted on the rear leg, and is removably attached to each front leg. Insertion of portions of the spring assembly into apertures in the front legs, allows the easel to stand in a tripod configuration. Removal of portions of the V-shaped spring assembly from the apertures in the front legs allows the legs to be folded together. In another embodiment, a collapsible brace assembly connects the rear leg to the front legs. The collapsible brace assembly comprises a pair of lateral struts extending between and engaging each of the front legs and a bracket connecting the lateral struts.

  • Patent number: 4296946
    Abstract: 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.

  • Patent number: 4171116
    Abstract: 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.

  • Patent number: 4116414
    Abstract: A book holder utilizes a flat rigid sheet having a bar fixedly secured thereto and extending along the marginal edge of the sheet and outstanding therefrom. Another sheet is hingeably secured to the bar carrying sheet at an opposed marginal edge. A flexible slat is secured to an opposite edge of the hingeable sheet and is also secured to the bar carrying sheet on a surface opposite to the location of the bar. A pair of clothespin-like pinching devices are attached to a pair of flexible cord-like members on the surface of the bar carrying sheet. In use, the book holder may be supported on a horizontal resting surface by having the bar carrying sheet left inclined relative to the supporting surface and utilizing the clamping devices to maintain the pages of a book open when the cover of the book rests on the bar carrying surface of the bar carrying sheet.

  • Patent number: 4042203
    Abstract: 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.

  • Patent number: 4017049
    Abstract: An easel having a tripod stand each of whose legs are telescopically mounted in tubular sleeves. A traveller unit is mounted on one of the sleeves and it has attached thereto cross brace members whose opposite ends are connected to the other respective sleeves. The traveller unit has a pair of legs extending angularly downwardly from the sides of a platform to form a channel between the legs. A cross member connects the tips of the legs and forms an opening into which a middle sleeve is received and which acts as a guide for the traveller unit as it slides upwardly and downwardly when setting up or collapsing the easel. A pair of pad holder units are attached to the other sleeves and are positionable on the sleeves at an infinite number of heights due to the frictional clamping nature of their structure when a load is supported thereon. Cooperating structure is formed on the sleeves and leg members which allow the length of the legs to be varied by utilizing resiliently biased leaf springs.
