Abstract: Described is a wind-up ride on toy with wind-up mechanism to propel a rider. The ride on toy comprises a body portion having a seat portion. A first axle is rotatably connected with the body portion, while a pair of wheels are connected with the first axle. The wind-up mechanism has an elastic band and a rotatable spool. The elastic band is fixed at a first end within the body portion and is attached with the rotatable spool at a second end. Additionally, the rotatable spool is operably connected with the first axle, such that winding the elastic band around the spool causes the elastic band to transition from a relaxed state to a stretched state and, upon allowing the elastic band to return to the relaxed state, the spool rotates the first axle and pair of wheels, thereby causing the wind-up ride on toy to propel forward.

Abstract: A mouse-type rehabilitation exercise device includes a mouse body on which a hand is mounted, a wheel moving the mouse body, a first motor aligning a position of the wheel such that the mouse body moves to a desired direction, a second motor rotating the wheel such that the wheel aligned by the first motor moves to a desired position, a clutch disposed between the second motor and the wheel to enable and disable a power transmitting to the wheel from the second motor, and a controller controlling a driving of the first motor, the second motor, and the clutch.

Abstract: A miniaturized steer roping practice apparatus may comprise a mobile base comprising a frame, an axle rotatably mounted on the frame to rotate about a rotation axis in a forward rotational direction for forward movement and a rearward rotational direction for rearward movement, and at least one drive wheel mounted on the axle. The apparatus may further comprise at least one leg movable with respect to the base, a leg actuation assembly configured to move the at least one leg in conjunction with rotation of the drive wheel, a cover mounted on the mobile base and having an exterior surface with a resemblance to a steer, and a motivating assembly configured to drive the axle in the forward rotational direction using stored energy. The motivating assembly may be configured to store energy by rotation of the axle in the rearward rotational direction.

Abstract: A windup toy vehicle is provided. In some embodiments, the vehicle may include a body and a wheel assembly that is connected to the body and that defines an axis about which the wheel assembly spins. The vehicle also may include a spring extending at least generally along the axis and having a first end and a second end that are respectively fixed and pivotable with respect to the wheel assembly. An arm may be coupled to the spring at the second end such that the arm and the second end pivot as a unit. The vehicle further may include a stop supported by the body and configured to block the arm from spinning with respect to the body.

Abstract: “Drop and pop” is a new rubberband-powered plastic pop-up toy. The toy features a unique suction cup delayed-release mechanism. (FIG. 9) The toy is made from flexible polyethelene plastic. (FIG. 1) The plastic is cut, creased, and folded into a box-like shape. (FIG. 6) Rubberbands fit in slots around the embodiment. (FIG. 7) When the corners opposite the rubberbands are pressed, the toy is flattened like an accordian. A vinyl suction cup adheres to a special semi-smooth surface, holding the embodiment flat, but slightly “cupped”. The toy is now “cocked” or “set”. (FIG. 8) The toy stays “set” for 2 to 5 seconds, unless dropped. When dropped on a flat surface, concave side down, the suction cup is forced loose. (FIG. 9) The rubberbands retract and the toy pops-up several feet. (FIG.

Abstract: A system comprising a rotating device and a support structure for the rotating device, wherein the support structure provides the power to the rotational device that is required to maintain spin. The rotating device has a housing with a base upon which the housing spins. An electric motor is contained within the housing that causes the housing to spin when the motor is activated. The base of the rotating device can be selectively placed on a support structure. The support structure can promote spinning in the rotating device in one of two ways. In the first way, the support structure provides electricity to the rotating device that powers the motor in the rotating device. In the second way, the support structure can generate a magnetic field that biases the rotating device against the charging port on the support platform.

Abstract: A system comprising a rotating device and a finger supported charging assembly for powering the rotating device. The rotating device has a housing with a base upon which the housing spins. An electric motor is contained within the housing that causes the housing to spin when the motor is activated. The finger supported charging assembly includes two contacts that are coupled to opposite terminals of a battery pack. The contacts are worn on opposing fingers and come into contact with the rotating device when the base of the rotation device is supported with the opposing fingers, when contacting the rotating device, the contacts on the opposing fingers provide electricity to the rotating device that powers the motor within the rotating device.

Abstract: A toy vehicle using a rubber band drive operates in conjunction with a guide line that is associated with the vehicle. The vehicle includes a plurality of guides through which the guide line is threaded. The guide line is suspended between anchor stakes and includes a splayed end portion at a terminus of the guide line. An obstruction on the guide line will interface with a ring on the vehicle. When the ring becomes fouled by the obstruction it will cause the deployment of a parachute from the vehicle.
