The side surfaces incorporate ridges (8, 8') which can be either continuous or segmented. On their inner sides, the spring leaves are provided with corresponding connecting elements (7, 7', 7") which snap behind the ridges described above. The production of a connection between two plug-in modules is effected first by a slight outward deflection of the spring blades from their rest position and by them subsequently snapping into position behind the ridges described above. The plug-in modules entail the advantage that even after a long time and frequent use, they can still be connected to each other easily or released from each other with equal ease.

    Abstract: The present invention relates to an improved rotational movement training device which includes a mounting board and a plurality of rotation devices which, when mounted on a mounting board, provide a training device which permits a user through experimentation to develop mathematical expressions and mechanical systems from elementary scientific facts and basic mathematics. The rotational devices includes gears or wheels of different diameters, pistons, torque levers, force and load pans, fulcrum-levers and devices to interconnect the wheels and pistons such as levers, belts, and adjustable spacers. The devices may be used in various combinations to develop and demonstrate mechanical movement concepts and expressions.

  • Patent number: 4950197
    Abstract: A modular crank toy includes a group of interchangeable elements which may be arranged creatively in multiple patterns. Rotary motion is transmitted from a drive unit with a crank handle to the other elements to provide entertaining and educational animated movements throughout various branches of the system assembled by the user. The movement is exhibited through a variety of different animated display-producing elements which rotate about their axes. Branches and circuits are created by joining such multiple, different animated display-producing elements together through a variety of junction units through which the rotational movement is transmitted.

  • Patent number: 4813903
    Abstract: A running toy having an integral and concealed transmission member permits easy construction of running toys having a desirable appearance. A block unit of the running toy includes a hollow cube or block having a concave portion for receiving other block units and a convex portion for coupling to other block units. The concealed transmission member is rotatably mounted within the hollow cube so as to permit successive block units to be connected, and top permit a drive force inputted to one end of a succession of block units, from a power unit and through a power transmission, to be output at another end of the succession of block units. The succession of blocks can be configured in any desired shape, such as a crane.

  • Patent number: 4784387
    Abstract: A game is provided for educational and recreational use which includes an outer housing with a cut out opening, having a main drive gear and a plurality of ball control gears around the cut out. A spring impelled pop up plate is provided within the housing onto which magnetically retained gear devices are placed to provide gear trains between the main drive gear and the ball control gears for rotation and discharge of balls used with the game. The plate position is controlled by a timer to cause the plate to pop up at the end of a predetermined time interval and to break up the gear trains formed by the gear devices. The game can then be reset for the same or for a different time interval.

  • Patent number: 4547160
    Abstract: An educational and building toy including a set of blocks of different lengths, having spaced-apart holes the number of which is determined by the proportional length of the block relative to a unit length. A plurality of discs and wafers are also provided, having holes and also indicia opposed thereon for the arithmetical operations of addition, subtraction, multiplication and division, and the cardinal numerals from one to ten, respectively. A plurality of flexible rods having axially-extending and circumferentially spaced ridges are provided. The peaks of the ridges define an outer diameter slightly larger than the diameter of holes in the blocks, discs and wafers, whereby a friction fit is obtained between the rods and perforated pieces to build different objects. The discs have a peripheral flange and a hub. The flange of some of the discs has inner gear teeth for meshing with the rod ridges. The hub hole of some of the discs have indentations for making a spline connection with the rod ridges.

  • Patent number: 4508348
    Abstract: The block game of the invention comprises an open-top box, including side walls and at least one floor. A plurality of similar regular blocks, designed to be removably contained by the box, are provided, wherein at least one of the blocks includes a movable part embedded therewithin. The movable part includes a top face, occupying a restricted portion of one of the faces of at least one of the blocks, to constitute an animatable portion. A manually-operated handle is carried by the box for driving the movable part within the associated block. At least two of the faces of each block are each adapted to carry a different graphical representation, each forming part of a different large image, wherein the animatable portion appears animated when the handle is activated.

  • Patent number: 4493669
    Abstract: A motorized toy is described which consists of self-propelled toy vehicles, station sections which can be incorporated along the course of a track for the vehicle and toy objects with movable parts which can be coupled with the station sections. Each toy vehicle can be operated both in a forwards and a backwards travel direction and can be stopped in both travel directions in a defined position in order to drive the toy object at a station section. Alternative hand-operated drive means may be provided at the station sections, and the track of the station section includes a start member having a transverse slot relative to the track section, the start member being able to adopt two positions relative to the track. A stop pin on the vehicle in one position of the start member is capable of latching into the slot thereof, latching being prevented in the other position.
