Abstract: A toy is constructed to include two unique linkages with the first linkage including a series of links located in a sequential array with each link pivotally connected to its next immediate adjacent neighbor and every other link operatively connected such that each link can pivot with respect to its neighbor and motion of a link pivotally connected to one side of a link is communicated to the link pivotally connected to the other side of that same link. This allows the linkage to propagate motion along the totality of the sequence in response to movement of any one link. The second linkage includes a first member which is pivotally connected to a rotating crank pin and connected at its upper end to a second lever which is pivotally connected to a body on which the crank pin rotates.

Abstract: A toy block constructed into one geometrically regular block formed from at least two nestingly interengagingly configured three-dimensional components having adjacent pairs of couplers interconnected by a generally H-shaped unitary hinge, the hinge having first and second opposing sides with an interconnecting web and a transversely extending plate portion. The sides are provided with axially aligned pairs of inwardly extending pivot stub projections. The plate portion includes a pair of oppositely extending, generally resilient, aligned catch arms with depending tangs which engage detents formed between the couplers for retaining the components in preferred position. The blocks may form humanoid objects, quadrupeds, or articles such as vehicles or furniture, or the like.

Abstract: This invention extends and generalizes a family of N-pronged (N=3,4,5,6, . . . ) star-based right prism puzzles given in the references cited. Here the overall shapes of the puzzles and the shapes of their various component structures need no longer be right prisms. Futhermore, each prong can have 3L component structures where L is no longer restricted to be one (L=1). Each N-pronged puzzle is comprised of three layers of component structures, each group of component structures in a layer can rotate together around a principal axis of the puzzle. The component structures in a prong of a puzzle appear in sets, each set is comprised of three component structures which can rotate jointly relative to all other component structures in a plane parallel to the principal axis of the puzzle. Each surface of a puzzle is to be initially assigned a unique color or picture. Various possible rotations (twists and turns) result in mixing up the surface configurations.

Abstract: A toy that can be used to simulate a vehicle or an aircraft is presented. The toy has a hood rotatably coupled to its front end which may be opened and closed. A rear portion is rotatably coupled to the rear end of the toy and may be rotated to two positions in order to simulate the tail portion of an aircraft and the back of a vehicle. Wing extensions are rotatably coupled to wing supports extending from the sides of the toy. A wheel is rotatably coupled to each wing extension. The wing extensions may be rotated to a vertical position so that the wheels will rest on a supporting surface and support the rear end of the toy. As such, the toy simulates a vehicle when the wing extensions are rotated to a vertical position and simulates an aircraft when the wing extensions remain in a horizontal position. Swingarms supporting simulated guns are rotatably coupled to the sides of the toy. A toy doll may be placed inside the toy and used in conjunction with the swingarms.

Abstract: A decorative device for hanging in and revolving in the wind to create a pleasant effect. The device has a number of slats of selected material mounted for arcuate positioning with respect to one another on a longitudinally extending strut also serves as a hanging device. The slats are rotatable on the strut and are held thereon in such a manner to provide positioning and holding friction between adjacent slats which allows the arcuate positioning of one slat to another to provide for the creation of a spiral design of any desired lead or pitch. By coloring selected areas of the slats while they are in a flat, unformed position, a particular decorative effect is obtained when the spiral is formed.

An operating button accessible when the case is closed can be depressed to actuate a mechanism which opens the lid of the case simultaneously causing the figure to rise from its stored position and to turn through a 90.degree. angle to an erect position in which it stands out from the case.

Abstract: A toy or novelty is disclosed which is in the form of standing mobile and has a series of parts each pivoted to another and each provided with eccentric weights. The weights and the arrangement of the pivots may be operative to pivot the parts from a position aligned with each other to a position extending from each other when the stability of the parts is sufficiently disturbed from the condition of stability when such parts are filed or folded. Alternatively, the parts may simply rock in an undulating fashion from the extended condition of stability. Some of the parts may have printed matter thereon which make sense or nonsense in one condition of stability or make sense or more sense in the other condition of stability. Some of the parts may include two parallel walls substantially to enclose other of said parts in the filed position. The parts may be circular in form and of reduced diameter in ascending order in one condition of stability.

Abstract: A toy having two modes of locomotion includes a body having a fly wheel rotatably mounted thereon. A further wheel is also rotatably mounted on the body. A plurality of appendage members each having ends are also mounted to the body about one of their ends. The appendage members are movable on the body between a retracted and extended position. When in the retracted position, the body is supported on a support surface by the fly wheel and the other wheel and can be moved across a support surface by energizing the fly wheel. When the appendage members are in the extended position, they contact the support surface such that the body is then supported by the appendage members. The fly wheel is connected to the appendage members via a gear train and appropriate crank disks and crank followers. Motion of the fly wheel can be transferred via the gear train, the crank disks and the crank followers to the appendage members so as to move the appendage members with respect to the body.

Abstract: An amusement device consisting of a manipulative puzzle having a plurality of hollow prism-shaped pieces rotatably connected by swivel joints. Each swivel joint comprises a base centrally formed in a wall of one prism and inserted through a hole located in a confronting wall of an adjacent prism. The base is secured by a screw passing through a washer fitting over the swivel joint base. In addition, a set of projections fit into corresponding depressions located on the respective confronting walls to hold the prisms in place until moved. An infinite number of configurations may be imparted to the puzzle by manipulating the prisms, however, it is preferred that the player manipulate an elongated rectangular shaft of interconnected prisms to attain a substantially spherical configuration.
