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, 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; a second side panel hingedly connected to the second side of the main panel; and a base panel, the base panel hingedly connected to the main panel, the base panel configured to secure to the first side panel and the second side panel to form a base stand.
Claims22
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 top and a bottom, a portion of the main panel extending along the first side and the bottom defining a first leg, a portion of the main panel extending along the second side and the bottom defining a second leg, the first leg and the second leg defining a bottom main surface at the bottom of the main panel, the top positioned opposite from the bottom on the main panel, 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 by a support hinge, the support panel extending upwards from the support hinge towards the top of the main panel, the support panel defining a locking tab configured to engage the locking aperture, the locking tab extending upwards from the support panel, the locking tab positioned between the support hinge and the top of the main panel;
- a first side panel hingedly connected to the first side of the main panel;
- a second side panel hingedly connected to the second side of the main panel;
- and
- a base panel, the base panel positioned between the first leg and the second leg, the base panel defining a first base end and a second base end disposed opposite from the first base end, the first base end of the base panel hingedly connected to the main panel by a base hinge, the base panel extending downwards from the base hinge towards the bottom of the main panel, the base panel disposed between the base hinge and the bottom of the main panel, the second base end defining a bottom base surface, the bottom base surface being substantially coplanar with the bottom main surface of the first leg and the second leg, the base panel configured to secure to the first side panel and the second side panel to form a base stand.

- forming a base stand comprising:
- securing the base panel to the first side panel;
- removably stabbing the first corner through the first side aperture;
- and
- engaging the first locking key with the enclosed locking slot;
- folding the ledge subpanel in a first rotational direction about a support hinge axis towards the front main surface;
- folding the locking subpanel in the first rotational direction about a subpanel hinge axis;
- extending the retention tab away from a retention tab cutout of the ledge subpanel and away from the ledge subpanel;
- and
- engaging the locking tab with a locking aperture to form a ledge, the locking aperture defined by the main panel between the support hinge and the base hinge, the support panel contacting the front main surface.
