Abstract
A painting is maintained in a clamp assembly connected to a leg of adjustable length. The leg of adjustable length and vertical bars of the clamp assembly form a tripod. The vertical bars may be connected to a pair of frame support legs at selectable locations thereon. The frame support legs and a pair of camp chair legs are respectively connected to ends of a camp chair seat. Because of the selectable locations, the seat is at a desired distance from the clamp assembly. The frame support legs are additionally connected to a tray whereon paints and brushes may be placed.
Claims16
A convertible easel having a clamp assembly that generally defines a rectangular frame of adjustable length whereon a work piece may be positionably retained, comprising:
- a first frame support leg in the general shape of an L-shaped bellcrank having a first relatively straight elongated leg portion and a first generally horizontal leg extension, said leg extension including an elongated slot therein, said slot extending substantially the entire length of said extension leg, for defining a multiplicity of positionable locations along said elongated leg slot for operably coupling said first frame support leg to said clamp assembly through said elongated slot extension;
- a second frame support leg, in the general shape of an L-shaped bellcrank having a second relatively straight elongated leg portion and a second generally horizontal leg extension, said leg extension including an elongated slot extending substantially the entire length thereof, said slot for defining a multiplicity of positionable locations along said leg extension for connection to said clamp assembly, the proximal end portions of said first and second frame support legs being adapted for resting on the ground without slipping and the like;
- a first camp chair leg rotatably connected near its mid point to the corresponding distal end portion of said first frame support leg;
- a second camp chair leg rotatably connected near its mid point to the corresponding portion of said second frame support leg;
- and
- a foldable seat having first and second ends connected to said first and second camp chair legs and to said frame support legs, respectively.

A portable chair and easel-like apparatus comprising:
- a generally rectangular frame means for operatively positioning and retaining a work surface;
- a chair means including a forwardly extending, elongated, L-shaped leg member having a first relatively straight slanted leg portion and a second generally horizontal leg extension, said leg extension including an elongated generally horizontal slot extending substantially the entire length thereof, said chair means being opperatively coupled to said frame means for enabling an artist or the like to sit down while engaging in artistic pursuits upon said work surface;
- fastening means for operatively engaging said elongated slot in said L-shaped leg member and the lower end portion of said frame for selectively moving said generally rectangular frame means toward and away from said chair means;
- and
- an elongated, positionally adjustable support means operatively coupled to said elongated slots of said leg means and responsive to said fastening means for mounting said frame means in a selected position with respect to said chair means and for selectively controlling the tilt of said frame means with respect to vertical.
2 more elements
A combination chair and easel assembly comprising:
- a first pair of generally rectangular, substantially parallel chair legs;
- a second pair of generally rectangular, substantially parallel, L-shaped elongated legs, said elongated legs having a length substantially greater then the length of said first pair of chair legs;
- a first support means operatively coupled proximate the top distal end portion of said first pair of chair legs and disposed substantially perpendicular thereto for forming a first chair support;
- a second support member operatively disposed between a corresponding portion of said elongated L-shaped leg members for supporting same and providing a second chair support;
- seat means operatively coupled between said first and second chair supports for forming a seat;
- a common support member operatively coupled between the mid portion of both said first pair of chair legs and said elongated pair of chair legs to pivotally attach said first and second pair of chair legs to enable the chair to open and close as desired;
- a pair of elongated longitudinal frame members having slot portions aligned with the axis thereof and extending substantially the entire length thereof;
- said L-shaped legs having the short portion thereof provided with a generally horizontal slot and fastening means is provided for passing through both the slot of the elongated longitudinal frame member and the slotted portion of the L-shaped leg member for selectively securing the elongated frame members against translational movement and for selectively positioning the elongated frame members in translation as desired;
- a first clamping member including clamping means thereon and having its opposite end portions secured by fastening means extending through the slot in the upper end of said elongated frame members and being loosened to allow downward positioning of said clamping member and tightened to lock the clamping member in a desired position;
- said clamping means including a curved surface and a lip portion for operatively engaging any size canvas, drafting board, or other work media and positionably retaining same during work thereon;
- a lower clamping member and means for operatively securing said clamping member within the lower portion of the elongated slot of said longitudinal frame members so as to enable selective vertical positioning and walking against movement once the correct working position has been established;
- a support member operatively coupled between the rear portion of said longitudinal frame members and generally perpendicular thereto, a two-piece telescopically adjustable leg means including locking means for selectively adjusting the length of said leg means and locking same at a desired position, positioning means operably disposed on the back of said support member for enabling said leg means to be pivoted thereabout so as to be folded toward and away from said leg portions and locked in a desired position by fastening means associated therewith.
