Abstract

A foldable canvas blank includes a working panel, the working panel comprising a top end, a bottom end, a right side, and a left side; a top end panel flexibly attached to the top end by a first top end hinge, the top end panel defining a top end locking slot extending through the top end panel; and a right side panel flexibly attached to the right side by a first right side hinge, the right side panel defining a right side edge surface distal from the working panel, the right side panel defining a right side locking slot, the right side locking slot intersecting the right side edge surface and extending inwards towards the working panel, the right side locking slot configured to engage the top end locking slot to secure the top end panel to the right side panel.

First claim

That which is claimed is:

1. A foldable canvas blank comprising:
a working panel, the working panel comprising a top end, a bottom end, a right side, and a left side;
a top end panel flexibly attached to the top end by a first top end hinge, the top end panel defining a top end locking slot extending through the top end panel; and
a right side panel flexibly attached to the right side by a first right side hinge, the right side panel defining a right side edge surface distal from the working panel, the right side panel defining a right side locking slot, the right side locking slot intersecting the right side edge surface and extending inwards towards the working panel, the right side locking slot configured to engage the top end locking slot to secure the top end panel to the right side panel, the right side locking slot defining a curved portion, the curved portion defining a right side locking tab.

2. The foldable canvas blank of claim 1 , wherein:
the right side panel defines a top right side surface and a bottom right side surface;
the right side edge surface extends between the top right side surface and the bottom right side surface; and
the right side locking slot intersects the right side edge surface between the top right side surface and the bottom right side surface.

3. The foldable canvas blank of claim 2 , wherein a portion of the right side edge surface between the right side locking slot and the top right side surface is substantially coplanar with a portion of the right side edge surface between the right side locking slot and the bottom right side surface.

4. The foldable canvas blank of claim 2 , wherein:
the right side panel defines an insertion tab between the right side locking slot and the top right side surface; and
the top end locking slot is configured to receive the insertion tab.

5. The foldable canvas blank of claim 4 , wherein:
the right side panel comprises a first right side subpanel, a second right side subpanel, and a third right side subpanel;
the first right side subpanel is attached to the working panel;
the third right side subpanel defines the right side edge surface;
the second right side subpanel is connected between the first right side subpanel and the third right side subpanel; and
the insertion tab is defined by the third right side subpanel.

6. A foldable canvas blank assembled into a folded canvas, the foldable canvas blank comprising:
a working panel, the working panel comprising a top end, a bottom end, a right side, and a left side;
a top end panel flexibly attached to the top end by a first top end hinge, the top end panel defining a top end locking slot extending through the top end panel, the top end panel being folded into an assembled end shape to form a top frame end of the folded canvas; and
a right side panel flexibly attached to the right side by a first right side hinge, the right side panel defining an insertion tab, the right side panel being folded into an assembled side shape to form a right frame side of the folded canvas, the insertion tab extending through the top end locking slot, the insertion tab positioned substantially perpendicular to the working panel.

7. The foldable blank canvas of claim 6 , wherein:
the top end panel defines a top end edge surface distal from the working panel;
the right side panel defines a right side locking slot; and
the right side locking slot engages a portion of the top end panel defined between the top end edge surface and the top end locking slot.

8. The foldable blank canvas of claim 7 , wherein:
the top end panel comprises a first top end subpanel, a second top end subpanel, and a third top end subpanel;
the first top end subpanel is connected to the working panel by the first top end hinge;
the second top end subpanel is connected to the first top end subpanel by a second top end hinge;
the third top end subpanel is connected to the second top end subpanel by a third top end hinge;
the third top end subpanel defines the top end edge surface; and
the right side locking slot engages a portion of the third top end subpanel between the top end edge surface and the top end locking slot.

9. The foldable blank canvas of claim 8 , wherein:
the right side panel comprises a first right side subpanel, a second right side subpanel, and a third right side subpanel;
the first right side subpanel is connected to the working panel by the first right side hinge;
the second right side subpanel is connected to the first right side subpanel by a second right side hinge;
the third right side subpanel is connected to the second right side subpanel by a third right side hinge;
the third right side subpanel defines the insertion tab and the right side locking slot; and
the top end locking slot receives a portion of the third right side subpanel positioned between the right side locking slot and the third right side hinge.

10. The foldable blank canvas of claim 7 , wherein:
the right side panel defines a right side locking slot; and
the right side locking slot interlocks with the top end locking slot.

11. The foldable blank canvas of claim 10 , wherein:
the top frame end of the folded canvas defines an inner top frame surface;
the right frame side of the folded canvas defines an inner right frame surface; and
the right side locking slot interlocks with the top end locking slot at a corner defined by an intersection of the inner top frame surface and the inner right frame surface.

12. A foldable canvas blank comprising:
a working panel;
a side panel flexibly attached to the working panel by a frame hinge; and
a frame panel flexibly attached to the side panel by a frame hinge, the frame panel attached to the side panel opposite from the working panel, the frame panel defining a top frame cutout and a bottom frame cutout, a first right inner hinge and a first left inner hinge each extending from the top frame cutout to the bottom frame cutout, the frame panel comprising:
a right inner flap attached to the first inner right hinge; and
a left inner flap attached to the first inner left hinge.

13. The foldable canvas blank of claim 12 , wherein:
the right inner flap comprises a first right inner subpanel and a second right inner subpanel;
the first right inner subpanel is attached to the first right inner hinge; and
the second right inner subpanel is attached to the first right inner subpanel by a second right inner hinge.

14. The foldable canvas blank of claim 12 , wherein the right inner flap extends inward from the first inner right hinge towards the left inner flap, and wherein the left inner flap extends inward from the first inner left hinge towards the right inner flap.

15. The foldable canvas blank of claim 12 , wherein:
