Convertible stretched canvas for artists

摘要

A multi-panel stretched canvas for artists which is capable of being selectively converted from a 2-dimensional configuration suitable for mounting on a vertical surface such as a wall, for instance, to a plurality of 3-dimensional configurations suitable for mounting on a vertical surface as a bas relief-like wall hanging or resting on a horizontal surface such as a table, for instance. The apparatus in its simplest sense is comprised of three panels of stretched canvas, each in the shape of an equilateral triangle, arranged in a specific configuration and joined together in series by pivotable connection means, preferably hinges. In 2-D form, the panels together form a trapezoid which may be wall mounted in the traditional fashion. By rotating the two end panels a distance behind the center panel the apparatus forms a 3-D bas relief like structure which when mounted to a vertical surface has three sides of the trapezoid in contact with the vertical surface. By rotating the two end panels further until their top edges contact each other, the apparatus forms a pyramid shape having a hollowed trilateral base and is suitable for display on a horizontal surface. Each panel is comprised of a triangular stretcher to which a linen or cotton canvas is mounted in conventional fashion.

1. An artist canvas for painting having a planar trapezoidal configuration and a pyramid configuration, said planar trapezoidal configuration comprising:
a planar trapezoidal shaped painting surface of paintable canvas, wherein the planar trapezoidal shaped painting is an isosceles trapezoid shape having reflection symmetry, said isosceles trapezoid shape having a longer base and a shorter base connected by a first and second edge of the isosceles trapezoid shape, wherein a center point of the longer base of the isosceles trapezoid shape includes a first separating line extending to a first endpoint of the shorter base, wherein the center point of the longer base of the isosceles trapezoid shape includes a second separating line extending to second endpoint of the shorter base; said pyramid configuration comprising: a pyramid shape having three outwardly facing planar surfaces of paintable canvas, wherein an apex of the pyramid shape is the center of the longer base, wherein one base edge of the pyramid shape is the shorter base, wherein the other two base edges of the pyramid shape are the first and second edges of the isosceles trapezoid shape, said artistic canvas further comprising: a first triangular canvas panel; a second triangular canvas panel having a first side adjacent to a side of said first triangular canvas panel; said first and second panels being pivotally connected; and a third triangular canvas panel having a first side adjacent to a second side of said second triangular canvas panel; said second and third panels being pivotally connected.
