Abstract:
A hanger device for sheet display material with non-damaging easy opening and closing capability, the hanger device comprising:a first extrusion piece having a mounting means and having a downwardly facing space adapted for receiving at least one piece of sheet material freely insertable therein, the space having a vertically oriented surface having at least one flexible tab protruding from the vertically oriented surface; a second extrusion piece pivotally mounted to the first extrusion piece by a hinge means, the second extrusion piece having a smooth holder surface facing the at least one flexible tab, the holder surface adapted for moving from a first position spaced apart from the flexible tab a sufficient distance to admit the sheet material with a non-contact insertion therebetween to a second position pressing against the at least one flexible tab to retain the at least one piece of sheet material sandwiched therebetween, the second extrusion piece further comprising a snap closure means for engaging the first extrusion piece, the snap closure means spaced apart from the holder surface, so that the second extrusion piece is adapted for being pivoted toward the first extrusion piece to engage the snap closure means to maintain the holder surface in the second position to retain the sheet material and further adapted for being pivoted away from the first extrusion piece to disengage the snap closure means and move the holder surface to the first position to release the sheet material; wherein the snap closure means comprises a flexible downwardly angled ridge of the first extrusion piece adapted for receiving an upwardly angled ridge of the second extrusion piece with a snap fit therebetween.
