Having Permanent Magnet (not Motor Associated) Patents (Class 446/129)
  • Patent number: 4990117
    Abstract: A toy vehicle travels on the surface of a travel board, following a path of magnetically attractive material. The toy vehicle has a single drive wheel located centrally on the bottom of the vehicle's body. The center of gravity of the vehicle resides substantially over the single drive wheel so that the vehicle is balanced. A magnet located in the front of the vehicle is attracted to the magnetic path on the travel board. The magnetic attraction directly steers the vehicle about the central drive wheel along the path.

  • Patent number: 4938730
    Abstract: A toy house has a lamp for illuminating an interior of the toy house and a switch which is magnetically actuated by placing a play piece having magnet disposed in its bottom surface area in proximity to an end of a lever which carries magnetically attractable material. When the end of the lever moves towards the play piece due to magnetic attraction, the opposite end of the lever causes two contacts to come into electrical contact with each other.

  • Patent number: 4917644
    Abstract: This magnetic toy includes a figure which may roll, where a part of the figure is magnetized with poles forming a magnetic force line around the figure. Also included is a belt with poles disposed along the length, the poles forming a magnetic force line. The figure is placed on the belt with the magnetic forces adhering the figure but allowing it rolling movement along the belt. The belt may be used around a person's extremities or torso. The belt may be incorporated into an article of apparel which does not have surface obstructions that would prevent rolling of the figure along the track of the belt.

  • Patent number: 4902011
    Abstract: A game apparatus which utilizes a plurality of magnetized playing pieces is disclosed. The magnetized playing pieces are in the shape of two-sided circular discs, one side having a north polarity and other side a south polarity. The common polarities are identified by a surface color or by indicia printed thereon.The playing pieces are displayed on a flat, horizontal playing surface, preferably within a circular boundary on a rough-textured surface such as provided by canvas, leather or etched glass. The pole strengths of the magnetic playing pieces are sufficient to permit the balancing of a playing piece obliquely on its edge in proximity to but spaced from a flat-lying piece of like upward-facing polarity.

    Abstract: A toy hot air balloon effectively utilizes a cover positionable over an inflated toy balloon. The toy includes a suspended gondola, and the interiorly positioned toy balloon is substantially hidden from view within the balloon cover. An optional lightweight circular plate positioned on a topmost portion of the cover allows the toy to float against a ceiling structure. When a lighter-than-air gas is not used to inflate the toy balloon, the top circular plate may be constructed from a material which permits the balloon to be attached to ceiling structures, such as over-head lamps, drop ceiling supports, etc.

  • Patent number: 4743214
    Abstract: A device for controlling the steering and direction of movement of an electrically operated toy vehicle wherein the toy vehicle has a rear axle driven by a gear train from an electric motor and a worm gear on the rear axle engaging a helical gear. The front wheels are connected by a tie rod and are adjustable together from a normal straight line position to an angular position to cause the vehicle to run in a curved path. An adjusting arm on the helical gear presets the angular position of the helical gear in which a reversal of direction will occur and a plurality of such angular positions may be provided. The direct current source or battery for motor power for the unit includes a pair of electromagnets in circuit with the source of electrical current, which is direct current, and with contact members. Energization of one of the electromagnets will, through a link, connection to the tie rod, cause the front wheels to turn in one direction.

  • Patent number: 4658928
    Abstract: An operable toy utilizes a metal sensing apparatus which includes a tuned circuit which includes a pick-up coil. The resonance frequency of the resonance circuit shifts when the pick-up coil senses a metal or magnetic object. A motor is normally driven in the absence of the sensing of a metal or magnetic object. When the metal or magnetic object is sensed, the frequency shift of the tuned circuit including the pick-up coil attenuates the frequency produced by an oscillator and as the voltage of the signal produced by the oscillator is attenuated, a level detection circuit produces a low output to thereby disconnect the power from the motor. Alternatively, the power to the motor may be reversed. Two metal sensing apparatuses may be utilized in an operable toy to cause the toy to follow a track of metallic or magnetic material.

  • Patent number: 4462596
    Abstract: A plurality of magnetized game pieces are inserted one by one in a piece holder frame of nonmagnetic material along a piece guide formed therein. In the row of game pieces, two adjacent pieces are held in contact with or spaced apart from each other under magnetic attraction or repulsion acting therebetween and the row length is variable and unpredictable. The piece holder frame may be formed with any desired number of piece guides in the form of a blind piece-insertion hole or an upstanding post. The game pieces may be permanent bar magnets themselves or take a composite form including a body portion of nonmagnetic material and one or more magnet pieces embedded in the body portion at each and thereof. To make the game further changeful, the game pieces may each be divided into two axial half sections which are joined together for relative rotation to enable reversion of its polarity.
