ABSTRACT:
TECHNICAL FIELD
The present invention relates to a variation of the invention disclosed and claimed in my U.S. Pat. No. 5,669,165, granted Sep. 23, 1997 and entitled “Picture Card”. More particularly, it relates to a display formed of two or more transparencies that are connected together in a way permitting rotation of at least one of the transparencies relative to the other transparency or transparencies, for the purpose of moving complementary images on the transparencies into and out of registry with each other.
BACKGROUND OF THE INVENTION
The Background Of The Invention set forth in my aforementioned U.S. Pat. No. 5,669,165 is hereby incorporation herein by this specific reference. An object of the present invention is to provide displays that in concept are like the displays disclosed in my U.S. Pat. No. 5,669,165, but which are characterized by new and unique structure for connecting the transparencies together and/or supporting the transparencies for rotation, one relative to another.
DISCLOSURE OF THE INVENTION
Displays of the present invention are basically characterized by a first plastic film transparency having an image on it and a second plastic film transparency having an complementary image on it. The first and second transparencies are positioned side-by-side. The first transparency has a circle of circumferentially spaced apart incisions in it. The second transparency includes film portions that project through the incisions in the first transparency and connect the transparencies together for at least some rotation, one relative to the other. Owing to this construction, one transparency can be rotated relative to the other to bring the images into a predetermined relationship, each to the other, so that the two images when viewed together will provide a predetermined combined image.
According to an aspect of the invention, the film portions of the second transparency that project through the incisions in the first transparency are peripheral portions of the second transparency.
According to another aspect of the invention, the incisions in the first transparency form radially outwardly directed flaps, and the peripheral portions of the second transparency extend radially outwardly through and beyond the incisions, along side the flaps.
According to another aspect of the invention, a third plastic film transparency is positioned along side the first transparency, on the side thereof opposite the second transparency. The first transparency has a second set of circumferentially spaced apart incisions in it. The third transparency includes film portions that project through the second incisions in the first transparency and connect the first and third transparencies together for at least some rotation of the third transparency relative to the first transparency.
The film portions of the third transparency that project through the second incisions in the first transparency may be peripheral portions of the third transparency. The second incisions in the first transparency may also form radially directed flaps. The peripheral portions of the third transparency may extend radially through and radially outwardly from the second incisions, along side the flaps formed by the second incisions.
According to yet another aspect of the invention, the second transparency may include incisions that form radially directed flaps constituting the film portions of the second transparency that project through the incisions in the first transparency. These flaps are circumferentially shorter than the incisions in the first transparency, so that some rotation of the transparencies is permitted.
According to yet another aspect of the invention, first and second circular transparencies of different diameters are connected together, one for rotation relative to the other, and the transparencies are slid, into an envelope that includes opposite sides and openings in the sides that are smaller than the diameters of the transparencies. The envelope is adapted to permit one to grasp the transparencies through the windows and move a peripheral edge portion of the larger transparency into contact with an interior portion of the envelope. This contact of the peripheral edge portion of the larger transparency with the envelope holds the larger transparency against rotation, allowing one to touch the smaller transparency where it is exposed through a side opening in the envelope, and rotate it relative to the larger transparency.
These and other advantages, and objects of the present invention will become apparent from the following detailed description of the best mode, when read together with the drawings, and the claims, which are all incorporated herein as part of the disclosure of the invention.
