DETAILED DESCRIPTION

(13) The invention includes a pre-assembled canvas for painting, which allows flat storage/transportation. It is easy to assemble to make up supports with assorted thicknesses. FIG. 1 and FIG. 2 show the pre-assembled canvas (1) made up of a foldable supporting structure (3) and a layered substrate for painting or printing (2). The substrate is a flexible flat piece. The supporting structure is made up of various flat/rigid panels, coplanar when deployed. When folded they are perpendicular among each other and interlocked.

(14) The layered substrate (2) has the same width and length of the foldable supporting structure (3). The shape of the layered substrate (2) for painting is square or rectangular with some square cuts (23) in each vertex.

(15) FIG. 3 shows the painting substrate (2) has a front face (21) and a rear face (22). The foldable supporting structure (3) is glued onto the rear face (22), made up of several panels separated by “V” longitudinal grooves (5) with a 90° angle. This allows perpendicular folding of each of the panels.

(16) FIG. 4 shows this foldable supporting structure (3) made up of a central panel (31), four side panels (32) forming a perimeter around the central panel and four rear panels (33) interlocked to each of those side panels (32).

(17) The central panel (31) of the supporting structure is quadrangular. It has a front face (311), a rear face (312), (FIG. 3). Its four edges have a bevel (313) between 45°/50°. This central panel is the rear support of the layered substrate (2) for painting.

(18) The side panels (32) are interlocked to each of the four edges of the central panel (31). They are rectangular and make up the thickness of the frame. Each of its four edges has a bevel (321) between 45°/50°.

(19) The rectangular rear panels (33) have smaller sides (331) and are cut on a side with an angle between 45°/50°. The edges have a bevel (332) between 45°/50°. These panels made up the rear edge of the supporting structure (3).

(20) FIG. 3 shows the sides of the square cut (23) on the layered substrate (2) matching the width of the side panels (32) plus the width of the rear panels (33).

(21) FIGS. 5, 6 and 7 show side panels (32) are folded perpendicularly to the central panel (31). The painting substrate (2) lies on the outer face. The remaining rear panels (33) are folded perpendicularly to the side panels (32) and parallel to the central panel (31). The ends (331) of the rear panels (33) are cut in an angle of 45° make up a continuous rear edge of the canvas.

(22) FIG. 8 shows the rear panels (33) with through holes (333) and interlocked to each of the smaller sides (331). FIGS. 9 and 10 show the fastening means are made up of a square-shaped piece (41) lying under each corner of the rear panels (33) when the structure is folded. It has through holes (42) and snap-on connectors (43).

(23) FIG. 11 shows the second option to attach the painting substrate (2) to the foldable support (3) on the supporting structure (3) by using staples (6) forming a perimeter on the rear panels (33) once the painting substrate has been assembled (6).
