Abstract: A ramp for a ride-on toy includes a base adapted to be positioned on a surface. The base has a top, sidewalls and an interior space. An end ramp section is also adapted to be positioned on the surface. A middle ramp section is removably connected between the base and the end ramp section. The end ramp section and the middle ramp section are sized to be removably positioned within the interior space of the base for storage. The ramp sections include a track formed on their top surfaces sized for miniature toy vehicles. The base features a roller wheel and a handle for pulling the base along the surface when the ramp sections and ride-on toy are stored in the base.

Abstract: An apparatus and method of controlling a mobile body that travels around a sound source which generates a sound. This apparatus includes a traveling information producer for producing traveling information, which is information about traveling of the mobile body; a direction estimator for estimating a direction in which the mobile body is located with respect to the sound source; and a position determiner for determining a position of the mobile body using the traveling information and the estimated direction of the mobile body.

Abstract: A toy submarine consisting of three components. Two of the components are an injection molded thermoplastic and the other is an ordinary rubber band. The plastic is slightly positively buoyant in typical tap water. The first molded component is the tailpiece and it includes a generally cylindrical body with an integrated propeller. The second molded component is the headpiece and it includes a generally cylindrical body with an integrated propeller that spirals in the opposite direction of the tailpiece propeller. Together they form a counter rotating propeller system. The bodies of both the tailpiece and the headpiece are hollow and open at both ends. One end of the tailpiece's body mates with one end of the headpiece's body such that their axes are aligned and the bodies are able to easily rotate relative to each other. The other ends of the tailpiece and headpiece each have a longitudinal slot.

Abstract: A toy bow-n-arrow bubble shooter system including a bow. The bow has a frame with a cylindrical member centrally interconnected thereto and an elastomeric string. The cylindrical member has a channel therein and a plunger member positioned within the channel. The plunger member has an interior end capable of engaging the channel of the cylindrical member. The plunger has an exterior end with a handle capable of engaging the elastomeric string of the frame. Included are a plurality of head attachments. Each head attachment has a hub-like member with a plurality of blades fixedly attached thereto. Lastly, a plurality of arrows are provided. Each arrow has a shaft with an upper portion that has a bulb head. The bulb head of each arrow snap couples within the hub-like member. Each arrow, with one of the head attachments coupled thereto, is positioned within the cylindrical member of the bow and capable of being released therefrom by action of the plunger member thereon.

Abstract: The present invention relates to a model glider having twin propellers, which includes a central frame which forms a body of the glider, a vertical tail and a pair of horizontal tails respectively provided on the rear part of the body, a pair of main wings horizontally provided on the middle part of the body, a rotating member, a power transmitting part, an elastic band member, a stopper, a driving part to rotate the twin propellers, and a link lever, wherein the elastic band member is elastically twisted by the rotation of the link lever and while the elastic band member is restored, its rotary power is transmitted to the propellers via the transmitting part and the driving part, so that the model glider has strong propulsive force by means of the twin propellers to increase gliding distance and user' interest.

Abstract: A main rotor is provided for use in a rotary winged model aircraft. The main rotor includes a rotor hub assembly rotatable about a vertical axis and at least two main rotor blades. Each of the main rotor blades extends in a radial direction from the rotor hub assembly. The main rotor blades each include a tip end positioned to lie in spaced-apart relation to the rotor hub assembly and a root end coupled to the rotor hub assembly for pivotable folding movement from an initial horizontal position perpendicular to the vertical axis about a horizontal axis through a desired folding angle of about 90.degree.. Forces transmitted to the rotor hub by the rotor blade during a crash-landing of a rotary winged model aircraft including the main rotor are minimized due to movement of the rotor blades through the desired folding angle.

Abstract: A slot track raceway has two side-by-side slots for enabling two racing cars to run around a closed loop track. A lap counter individually associated with each closed loop is set to a selected number of laps for establishing the length of a race. Each completion of a lap causes the associated lap counter to count down. When the lap counter counts down to zero, a spring biased hinged track section snaps into alignment with an upwardly inclined ramp so that the car winning the race flies off the track, thus escaping or leaping from the track.

Abstract: A hobby aircraft arranged for vertical flight aerodynamics. A substantially-planar body is symmetrical about a central axis. An upper blade is fixed to the bottom of the body. An elastic band is aligned with the central axis for powering a lower blade that is in spaced relation to the upper blade. Rotation of the second blade is controlled by means of a locking mechanism to assure that gravity alone powers the final stage of aircraft flight.

Abstract: A multi-disc flying device is disclosed in which outer and middle discs rotate in opposite directions by a force generated by the unwinding of a torsion spring. Downwardly extending deflecting plates on each disc generate an upward force during rotation to prolong the flight of the device. An inner disc rotatably attached to the middle disc has a normally curved rudder assembly to impart a curved flight path to the device so that it will return to its launching point. A propeller is driven by relative movement between the rudder and the inner disc to provide a propulsive force to the flying device.

Abstract: In a helicopter toy, a plurality of rotor blades are mounted to a flying body for rotation about a rotational axis and for angular movement about their respective pivotal axes extending perpendicularly to the rotational axis so that the rotor blades have their respective angles of attack which can be altered in pitch. An attack-angle altering unit is provided for altering the angles of attack of the respective rotor blades such that, when a power is transmitted to the rotor blades from a power source to rotate the rotor blades about the rotational axis, the angles of attack of the respective rotor blades are brought to their respective plus pitches to climb the flying body, while, when the transmission of the power from the power source to the rotor blades is released, the angles of attack of the respective rotor blades are brought to their respective minus pitches to cause the flying body to descend.

Abstract: An autorotative flyer comprises a circular root portion integral with a wing portion; the root being generally circular and providing a counterweight of from 55-85%, preferably 70-72%, of the total weight of the flyer and locating the center of gravity of the flyer behind the leading edge of the wing a distance equal to from 28-29% of the mean aerodynamic chord of the wing and at a spanwise distance from the root end of the flyer of from 10-21% of the root end to wing tip span; the wing of the flyer having curved leading and trailing edges and a curved tip with an integral spar along the leading edge and a wing area providing a wing loading of not more than about 0.5 lbs./ft.sup.2 ; and, optionally, scallops on the trailing edge of the wing and a vane on the edge of the root section concentric with the center of gravity.

Abstract: A flying disc toy has at least two circular spinners rotatably mounted upon a centered axle. Each spinner has a number of fins which cause the spinner to rotate when thrown into the air. The spinners rotate in counter direction, thereby causing the toy to lift when thrown with a twisting motion. The subject matter of this application is disclosed in Disclosure Document #254258, dated June 4, 1990.

Abstract: This hand flyer is so designed as to be of a specific one piece construction that includes certain aerodynamic characteristics that enable it to be thrown upward vertical, whereupon its descent will perform a spiral motion. Primarily, it consists of a body having a tapered wing portion and a forward head portion projects outward from the body.
