Easel

Claim 2

An easel comprising a. at least three sleeves, b. means pivotally securing said sleeves together at one of their ends to form the top of the easel, c. a leg telescopically mounted in each of said sleeves, d. brace means connecting said sleeves at a position spaced downwardly from the top of said easel, said brace means comprising a traveller unit mounted on one of said sleeves, said one of said sleeves having a cap member at the end remote from the top pivotal means, cross brace members connecting said other sleeves to said traveller unit, said traveller unit comprising a platform, a pair of legs extending angularly downward from the sides of the platform to form a channel between the legs and receiving said one of said sleeves therein and means extending between said traveller legs closing the open end of the channel whereby an opening is formed which receives the sleeve as the traveller moves downwardly within said opening during setting up, said cap member limiting the downward movement of the traveller, the traveller unit platform extending toward the said one of said sleeves at the cap member at an angle whereby a force tending to collapse the opened legs will engage the platform with the sleeve and tend to move the traveller unit downwardly.

Claim 3

An easel as recited in claim 1 further comprising pad holder means having at least two units, each unit being formed with an outwardly extending arm member, a pair of legs extending angularly upwardly from the sides of the arm member to form a channel between the legs and means closing the open end of the channel whereby an opening is formed which receives the sleeve upon which the pad holder units travel when their height is adjusted upwardly or downwardly.

Claim 4

An easel as recited in claim 1 wherein said sleeves are square and said legs are tubular and further comprising nylon bearing shoe means attached to the outer surface of said legs across one diameter thereof to reduce friction when the legs are telescopically moved within said sleeves and to provide a bearing for a tubular leg in a square sleeve.

Claim 5

An easel comprising a. at least three sleeves, b. means pivotally securing said sleeves together at one of their ends to form the top of the easel, c. a leg telescopically mounted in each of said sleeves, d. pad holder means having at least two units, each unit being formed with an outwardly extending arm member, a pair of legs extending angularly upwardly from the sides of the arm member beyond said sleeve to form a channel between the legs in which said sleeve is located and means beyond said sleeve closing the open end of the channel whereby an opening is formed which slidably receives the sleeve upon which the pad holder units travel when their height is adjusted upwardly or downwardly.

Claim 6

An easel comprising a. at least three sleeves, b. means pivotally securing said sleeves together at one of their ends to form the top of the easel, c. a leg telescopically mounted in each of said sleeves, d. pad holder means having at least two units, each unit being formed with an outwardly extending arm member, a pair of legs extending angularly upwardly from the sides of the arm member beyond said sleeve to form a channel between the legs in which said sleeve is located and means beyond said sleeve closing the open end of the channel whereby an opening is formed which slidably receives the sleeve upon which the pad holder units travel when their height is adjusted upwardly or downwardly.

Claim 7

An easel comprising a. at least three tubular sleeves, b. means pivotally securing said tubular sleeves together at one of their ends to form the top of the easel, c. a leg telescopically mounted in each of said tubular sleeves, d. brace means connecting said tubular sleeves at a position spaced downwardly from the top of said easel, said brace means comprising a traveller unit mounted on one of said sleeves, and cross brace members connecting said other sleeves to said traveller unit, said traveller unit comprising a platform, a pair of legs extending angularly downward from the sides of the platform to form a channel between the legs and means closing the open end of the channel whereby an opening is formed which receives the sleeve that travels upwardly and downwardly within said opening during setting up and collapsibly folding said easel, e. each of the ends of said cross brace members spaced from the traveller unit being pivotally connected to pins mounted on the said sleeves, the ends of said brace members having a oversized aperture as compared to the diameter of said pins, the area around said apertures being curved upwardly to provide a concave bearing surface for a mating convex surface on said pins thereby producing a form of a universal joint.

Claim 8

An easel comprising a. at least three tubular sleeves, b. means pivotally securing said tubular sleeves together at one of their ends to form the top of the easel, c. a leg telescopically mounted in each of said tubular sleeves, d. brace means connecting said tubular sleeves at a position spaced downwardly from the top of said easel, said brace means comprising a traveller unit mounted on one of said sleeves, and cross brace members connecting said other sleeves to said traveller unit, said traveller unit comprising a platform, a pair of legs extending angularly downward from the sides of the platform to form a channel between the legs and means closing the open end of the channel whereby an opening is formed which receives the sleeve that travels upwardly and downwardly within said opening during setting up and collapsibly folding said easel, e. each of the ends of said cross brace members spaced from the traveller unit being pivotally connected to pins mounted on the said sleeves, the ends of said brace members having a oversized aperture as compared to the diameter of said pins, the area around said apertures being curved upwardly to provide a concave bearing surface for a mating convex surface on said pins thereby producing a form of a universal joint.
