Abstract

A foldable easel blank includes a main panel defining a first side and a second side, the first side positioned opposite from the second side, the main panel defining a locking aperture extending through the main panel from a front main surface to a rear main surface; a support panel hingedly connected to the main panel, the support panel defining a locking tab configured to engage the locking aperture; a first side panel hingedly connected to the first side of the main panel by a first side hinge; a second side panel hingedly connected to the second side of the main panel by a second side hinge; and a base panel positioned between the first side hinge and the second side hinge, the base panel configured to engage the first side panel and the second side panel to form a base stand.

First claim

That which is claimed is:

1. A foldable easel blank comprising:
a main panel defining a first side and a second side, the first side positioned opposite from the second side, the main panel defining a locking aperture extending through the main panel from a front main surface to a rear main surface, the front main surface positioned opposite from the rear main surface;
a support panel hingedly connected to the main panel, the support panel defining a locking tab configured to engage the locking aperture;
a first side panel hingedly connected to the first side of the main panel by a first side hinge;
a second side panel hingedly connected to the second side of the main panel by a second side hinge; and
a base panel positioned between the first side hinge and the second side hinge, the base panel configured to engage the first side panel and the second side panel to form a base stand; and
wherein:
the main panel defines a top and a bottom;
the base panel is hingedly connected to the main panel by a base hinge;
a first base panel cutout extends from the bottom to the base hinge;
a second base panel cutout extends from the bottom to the base hinge;
a first leg is defined between the first base panel cutout and the first side hinge;
a second leg is defined between the second base panel cutout and the second side hinge;
the base panel is positioned between the first leg and the second leg;
the first leg and the second leg define a bottom main surface at the bottom;
the base panel defines a bottom base surface at the bottom; and
the bottom main surface is substantially coplanar with the bottom base surface.

2. The foldable easel blank of claim 1 , wherein:
the first side panel defines a first front surface and a first rear surface;
the first front surface is positioned opposite from the first rear surface;
the first side panel defines a first side aperture extending from the first front surface to the first rear surface; and
the first side aperture is configured to receive a first corner of the base panel.

3. The foldable easel blank of claim 2 , wherein:
the base panel defines an enclosed locking slot disposed proximate to the first corner;
the first side panel defines a first locking key disposed within the first side aperture; and
the first locking key is configured to engage the enclosed locking slot when the first corner of the base panel is inserted through the first side aperture of the first side panel.

4. The foldable easel blank of claim 1 , wherein the support panel comprises:
a ledge subpanel defining a first ledge end and a second ledge end, the first ledge end positioned opposite from the second ledge end, the first ledge end hingedly connected to the main panel; and
a locking subpanel defining a first locking end and a second locking end, the first locking end positioned opposite from the second locking end, the first locking end hingedly connected to the second ledge end by a subpanel hinge, the second locking end defining the locking tab.

5. A method for assembly a folded easel comprising:
obtaining a foldable easel blank in an unfolded position, the foldable easel blank comprising:
a main panel defining a top and a bottom, the main panel defining a front main surface and a rear main surface, the front main surface positioned opposite from the rear main surface;
a first side panel hingedly connected to the main panel by a first side hinge;
a second side panel hingedly connected to the main panel by a second side hinge; and
a base panel hingedly connected to the main panel by a base hinge, a first base panel cutout extending from the bottom to the base hinge, a second base panel cutout extending from the bottom to the base hinge, the base panel positioned between the first side hinge and the second side hinge, a first leg defined between the first base panel cutout and the first side hinge, a second leg defined between the second base panel cutout and the second side hinge, the base panel positioned between the first leg and the second leg, the first leg and the second leg defining a bottom main surface at the bottom, the base panel defining a bottom base surface at the bottom, the bottom main surface being substantially coplanar with the bottom base surface in the unfolded position; and

folding the first side panel about the first side hinge towards the rear main surface;
folding the second side panel about the second side hinge towards the rear main surface;
folding the base panel about the base hinge towards the rear main surface; and
forming a base stand, forming the base stand comprising:
securing the base panel to the first side panel and the second side panel.

6. The method of claim 5 , further comprising folding a support panel about a support hinge towards the front main surface to form a ledge of the folded easel, the support panel being hingedly connected to the main panel by the support hinge.

7. The method of claim 5 , wherein:
folding the base panel about the base hinge towards the rear main surface comprises folding the bottom base surface of the base panel away from the bottom main surface of the main panel;
the base panel defines a first base end and a second base end;
the first base end is disposed opposite from the second base end;
the first base end hingedly is connected to the main panel; and
the second base end defines the bottom base surface.

8. The method of claim 5 , wherein securing the base panel to the first side panel and the second side panel comprises engaging a corner of the base panel with a side aperture defined by the first side panel.

9. The method of claim 8 , wherein securing the base panel to the first side panel comprises engaging a locking key with an enclosed locking slot, the locking key defined by the first side panel within the side aperture, the enclosed locking slot defined by the base panel.
