Abstract: One embodiment of an occupant propelled roundabout (“roundabout”) may have a body. The roundabout may also have a carrier, which may be rotatably carried by the body and may also have a seat assembly adapted to carry an occupant. In addition, the roundabout may also have a drive mechanism pivotally coupled to the seat assembly such that the drive mechanism may be movable between a deployed position and a retracted position. The drive mechanism may be moved toward the deployed position in response to the occupant operating the drive mechanism. Also, the roundabout may have a biasing member, which may be operably connected between the drive mechanism and the carrier so that the biasing member may move the drive mechanism toward the retracted position.

Abstract: The present invention relates to a multi-functional balance rotary disk includes a circular disk body having a center provided with a circular base. The circular base is recessed to form a plurality of successive tracks, so that a ball can roll in the tracks. The disk body has a bottom formed with an arc-shaped face for allowing rotation of the disk body. A plurality of holding handles are secured on corners of the disk body, for allowing hold of a user. The child may stand on the disk body for training balance of his hands, while the child can use swinging action of his feet to swing the disk body, whereby the ball continuously rolls in the tracks so that the child can watch the rolling ball for training his eyes. The disk body can also function as a skateboard or a swing.

The circular base is recessed to form a plurality of successive tracks, so that a ball can roll in the tracks. The disk body has a bottom formed with an arc-shaped face for allowing rotation of the disk body. A plurality of holding handles are secured on comers of the disk body, for allowing hold of a user. The child may stand on the disk body for training balance of his hands, while the child can use swinging action of his feet to swing the disk body, whereby the ball continuously rolls in the tracks so that the child can watch the rolling ball for training his eyes.

Abstract: A conical recreational device for providing recreation and exercise. The conical recreational device includes a tubular housing having a first open end and a second open end. The tubular housing has a generally frusto-conical shape. A peripheral lip is attached to and extends around an edge of the first open end. A sleeve for extending into the first open end of the housing has a first end, a second end and a peripheral wall extending between the first and second ends. The first end of the sleeve is open and has a perimeter edge has a flange thereon. The flange comprises a hook extending toward the second end. The flange may be extended over the lip on the housing for rotationally coupling the sleeve to the housing.

Abstract: An implement to be used as a plaything by children and as training equipment by grownups, includes a hoop of a diameter larger than the height of a person standing on its inside surface and treading forwards with the aim to roll the hoop along a floor surface. A chassis frame is slidingly attached to the two lateral edges of the hoop. The chassis frame supports a front wheel and a steering handle extending towards the hands of the person in the hoop. Treading on the hoop's inside surface propels the hoop along the floor while the front wheel is steered by the user. A hoop sized for adults can be used as a training implement by mounting it in rotatable alignment on a stationary base. The training implement may be configured for use in various positions, either upright, or when sitting and even while laying down.

Abstract: A playing wheel rotatably secured on a base fixed on a fixture of a playground includes a solid spoke portion diverging radially outwardly from a central hub portion of the playing wheel and a plurality of finger slots cut out in a periphery portion of the wheel adjacent to an outermost rim portion of the wheel to prevent injury to a child's fingers or hand as protected by the solid spoke portion of the wheel by eliminating the big openings easily entrapping a child's hand as formed in the spoke portion of a conventional playing wheel.

Abstract: A vehicle that provides safe and stable transportation of passengers, yet allows passengers, including wheelchair-bound passengers, to quickly enter and exit the vehicle without climbing up or down and without stepping on the seats has been provided. The preferred embodiment of the vehicle of the present invention, which is towed by an underwater cable system, has a double hull construction with a fixed outer hull and a moveable inner hull or seating platform, which may be raised or lowered. In the ride dispatch area, the inner hull is raised so that the floor of the inner hull is even with that of the vehicle gunwales and the dispatch floor level. During the ride, the hull is lowered so that the floor of the inner hull is below the level of the vehicle gunwales, and thus the vehicle forms a secure and stable seating compartment configuration for the duration of the ride. The vehicle is further equipped to secure wheelchair-bound guests to the inner hull quickly and easily.

Abstract: A portable rider-propelled roundabout includes a platform having a circular track formed by a pair of semi-circular halves, a plurality of pedal-propelled riding cycles, and a revolving mechanism operable for supporting the riding cycles upright on the circular track for undergoing revolving movement therealong about a center point defined by the circular track. The platform also including reinforcing frameworks extending between and rigidly connected with spaced portions of the respective track halves and pivotal hinges connecting the track halves together for pivotal movement about a longitudinal axis so as to permit converting the platform between a transport condition in which the track halves are disposed in a side-by-side folded relation to one another and a deployed condition in which said track halves are disposed in an unfolded coplanar relation with one another.
