Abstract: Two components slide with respect to one another, and hold a stack of cards. A first component includes three members extending into a chamber formed by its C-shaped cross-section. When the components are slid apart, the first card in the stack is partially exposed. The card is pushed back past the outer members providing resistance to prevent the cards from moving while allowing only the top card to be pushed past the outer appendages to expose the next card. When the components are pushed together, a bump on an L-shaped component assures that the cards are aligned in a stack. The two outer members include tangs at their terminations that retain a stack of cards within the chamber and prevent them from sliding past. Between the outer members, a central spring extends in an angled configuration into the chamber and presses against the cards and frictionally retains them in position within the chamber.

Abstract: A sliding panel display device for displaying two different images, such as photographs, comprises front and rear panels, each bearing a different image or photograph, and each divided into a plurality of parallel strips. The strips of the front panel are arranged as slidable interleaves between the strips of the rear panel, whereby the strips of the front panel are movable between a first position, in which the strips of the rear panel are completely covered by the strips of the front panel, and a second position, in which the strips of the front panel are completely hidden behind the strips of the rear panel whereby in the first position, only the image on the front panel is visible, while in the second position, only the image on the rear panel is visible. These panels are held together in the interleaved relationship in a holder that forms a frame. The rear panel is fixed in the holder, while the front panel is held in the holder so as to be slidable between the first and second positions.

Abstract: A picture frame has a plastic rear wall wherein a bearing member is mounted so as to be pivotable about an axis orthogonal to the rear wall between a first and a second end position spaced by 90.degree.. A prop is hinged to the bearing member so as to be unfoldable from a recess of the rear wall into a first spread-apart position when the bearing member assumes the first end position and into a second spread-apart position when the bearing member is in its other end position. In either spread-apart position, the prop defines a different angle with the rear wall, said angles being determined by stops on the rear wall cooperating with stops on the prop.
