ABSTRACT:
A locking easel stand display mount apparatus has a display panel and a backing panel having attached to the display panel. An easel stand is cut into the backing panel so that the easel stand can have angular movement away from the backing panel on a hinge. An easel locking tongue is formed in the easel stand for movement with respect thereto when the easel stand is moved away from the backing panel and engages the first panel to lock the easel stand in place. A hinge stiffening portion is formed in the easel stand hinge and includes a pair of parallel cuts in the backing panel at predetermined positions transverse to the easel stand hinge bending line in the panel. The hinge stiffening portion has a pair of bending lines between the two cuts and spaced from the hinge bending line so that an easel stand will bend on a plurality of interrupted hinge lines and produce a hinge stiffening portion. When the easel stand portion is rotated, the hinge stiffening portion pops up to form a bridge-like stiffening portion.
