  • Patent number: 11443664
    Abstract: There is disclosed a transformative display that, in a first configuration, appears as a first scene. A mechanism is provided to cause elements of the display to move from the first configuration to a second configuration, displaying a second, different scene. The elements are in the form of panels that fit into recesses in a platform in the first configuration. These panels may include features that extend above the surface of the platform to form other elements of the first scene. When the display moves to the second configuration, the panels swing upward from the platform, creating elements of the second scene. In the second configuration, features extending from the panels meet to other elements of the second scene.

    Abstract: A construction/puzzle toy comprised of pairs of half-polyhedrons that are connected along one margin by a living plastic hinge. A chain is formed by permanently attaching adjacent pairs to each other by an axle-like component that rotatably joins two half-polyhedrons to form an entire polyhedron. This combination of a rotatable joint within each whole polyhedron and a hinge joint between adjacent polyhedrons allows the chain to be rearranged into a large number of different shapes. A preferred assembled shape for a chain of the polyhedrons is that of a cube. A closed ring of eight cuboidal polyhedrons forms a challenging puzzle that can be reconfigured to form a large cube with four cuboidal polyhedrons on each face. Likewise, a closed chain of 27 cubes can create a large cube with 9 cuboidal polyhedrons per face. Chains that are not closed to form a ring can be used to construct a wide variety of interesting shapes. The invention can be equipped with small knob-shaped tips to the axle-like component.
