Abstract: A toy projectile launcher includes a body having a magazine for storing at least one cylindrical projectile. The body has an elongate barrel in communication with the magazine. The barrel is shaped for travel of the projectile from the magazine to an exit end. The barrel has an intermediate opening between the magazine and the exit end. A drive wheel is powered by a motor to spin about an axis of rotation. The drive wheel can be coupled to the body by a drive wheel biasing member. The drive wheel intrudes into the barrel though the intermediate opening to contact and propel the projectile down the barrel. The drive wheel can include a resilient part. The axis of rotation of the drive wheel can deviate from being perpendicular to the length of the barrel by a predetermined angle selected to impart spin to the projectile.

Abstract: An inexpensive apparatus for powering a toy plane including a rubber band motor which is connectable to the plane's propeller and to a winding mechanism, including a gear mechanism which is activated by a handle. As the handle is repeatedly squeezed and released by the user, the motor is wound up. An anti-reversing ratchet is coupled with the motor to prevent unwinding until the user wishes to launch the plane.

Abstract: The present invention is directed to providing a biased releasable connection system that is compact, lightweight, inexpensive and low-power. The system comprises a releasable object that is biased against a retaining mechanism until the connection is released. The system further comprises a small and lightweight shape memory alloy member to actuate the release of the connection. When the connection is released, the biasing mechanism propels the releasable object in a particular direction. The compact design of the system is partly attributable to the strategic utilization and positioning of the shape memory member within the system.

Abstract: There is provided a gyro helicopter generally comprising a fuselage, a rotor mast extending upwardly from the top of the fuselage, a rotor adapted to autorotate when the gyro helicopter moves forward, and drive means mounted to the fuselage for driving the gyro helicopter in at least a forward direction and for causing the gyro helicopter to perform yawing motions. The rotor of the gyro helicopter includes a hub mounted to the rotor mast, at least two rotor arms extending radially from the hub, and at least two corresponding lifting blades, a leading edge of each of the lifting blades fixedly mounted to a corresponding one of the rotor arms.

Abstract: A vehicle with a novel vehicle body formed of polyvinylchloride plastic (“PVC”) or similar plastics. Generally, the vehicle body is formed by folding or vacuum forming one or more sheets of PVC into shapes specific to one type of vehicle. The type of vehicle can be any type of vehicle, including planes, cars, trains, tanks, of the like. The vehicle body also incorporates novel structural elements such as curves, folds or troughs that stiffen the PVC and facilitate assembly of the vehicle body.
