Abstract: The present invention includes: a base section configured such that, taking the unit edge length D1 to be 1 and a cube expressed as 1×1×1 to be one unit size, the base section has a parallelepiped shape in which one or more 1-unit sizes are conjoined, and is composed of an open, hollow face taken to be the bottom, four lateral walls 3B, and a roof 3A; and cylindrical projections having a cylindrical shape and provided on the outer face of one or more of the roof 3A and the lateral walls 3B, with a diameter D2 being equal to or greater than 0.4 but less than 0.6 with respect to the unit edge length D1, and a height being (1?diameter)×(0.4 to 0.5 inclusive).

Abstract: A detachably coupling device for a detachably coupling two bodies. The detachable coupling device on each of the bodies comprises a magnet movably mounted on the body and having a north pole and a south pole. The strength of the magnetic field existing between the magnets on the first body the second body may be selected to allow, preferably, manual detachable coupling of the two bodies. As the two bodies are placed closer together until the magnets are contiguous, the movement of the magnets will cause the magnets under the influence of the magnetic field to move until the north pole of one magnet is contiguous the south pole of the other magnet thereby coupling the two bodies together.

Abstract: A toy vehicle adapted to run on a track wherein the track defines a preselected pathway with a preselected geometrical configuration. A plurality of motion command modules are mounted at predetermined locations on the track and each motion command module has a detectable motion pattern array and the motion pattern array of each command module may be different than the other motion command modules. The toy vehicle has a motion producing device such as an electric motor for providing movement characteristics of the toy vehicle on the track in response to receipt of a motion control signal. A pattern detection unit is mounted on the vehicle and detects, for example, by optical detection, the detectable movement pattern array of each motion command module and generates the motion control signal in response thereto.

Abstract: An articulated doll arrangement having a head, a body, arms, upper legs, lower legs and hands. The parts of the articulated doll are interconnected to provide simulated anthropomorphic movements between various of the parts. A central connecting member extends through the hollow body means and projects from the top of the body upon which the head having a simulated neck is pivotally mounted. The remote end of the central connecting has the two upper legs pivotally mounted thereon adjacent the bottom edges of the body. A simulated shoulder joint is provided on the sides of the body adjacent the top and the arms are pivotally connected at the shoulder connecting joints. Hands are detachably mounted in the remote ends of the arms. Lower legs are pivotally connected to the upper legs at a simulated knee joint.
