Abstract

A device for displaying multiple images in an animation-like manner is provided. The device includes an outer shell having a pair of opposed transparent lenticular surfaces and a pair of opposed side walls extending between opposed outer edges of the lenticular surfaces thereby forming a hollow rectangular cavity. The device also includes a generally rectangular slide insertable through an opening in the first end of the cavity. Interleaved images are positioned on the opposed faces of the slide. The device further includes a part for reciprocating the slide in the cavity thereby altering the appearance of the displayed image. The reciprocating part includes a detent slot formed in an interior region of each of the side walls of the outer shell and a corresponding pair of spring bar mounted detent tabs for engaging the detent slots. A spring bar is positioned generally parallel to the second end of the slide and dihedral spring leaves are positioned in a center of the spring bar. The spring bar and the spring leaves bias the slide away from the second end of the outer shell. A push bar extends from the first end of the slide through the opening. The push bar enables the slide to be reciprocated in the outer shell. Pushing the push bar against the force of the spring bar and spring leaves alters the appearance of the displayed image.
