Abstract: Wheeled personal mobility vehicles with extremely thin stowed profiles are provided, which in one embodiment, include a plurality of movable, collapsible wheel axle assemblies which are supported on a support frame and movable between an operative state where the wheels provide rolling support, and a collapsed state where the wheels are moved into the side elevational profile of the device. The embodiment provides for both integrated propulsion and steering linkage to the wheels when they are manually moved into their operative position, along with a collapsible steering mechanism, a support base and at least one collapsible seat. This embodiment may also provide for pedal power, battery, fuel cell or motive power as well as remote control operation.

Abstract: There is a walking cane, for supporting and balancing a user, and allowing a user to retard forward motion. The walking cane includes a base, having a wheel rotatably coupled thereto. The cane further includes a braking member, coupled to and positioned relatively above the base, having a contact portion that contacts the wheel to retard the wheel's rotation when a threshold downward force is applied to the cane.

Abstract: A device for attachment to a bicycle which includes a flat strap of semi-rigid plastic a substantial portion of which is straight terminating in a free distal end. A portion of the strap is bent at a proximal end thereof against itself forming an area of double thickness. A fastener is engageable with the strap at the proximal end thereof to affix the apparatus to the bicycle so that the distal end of the strap may be sequentially engaged by the spokes of a rotating bicycle wheel to simulate the sound of a motor.

Abstract: A ride-on vehicle for children comprising a body with a seat, a plurality of wheels rotatably coupled to the body, a steering mechanism operable by a child seated on the seat, and a frame forming a portion of the body. The frame includes a plurality of interconnected frame members, with at least one of the frame members comprising an audio-visual device configured to emit at least one of a light and a sound upon the occurrence of a triggering event. The audio-visual device has opposing end regions that are connected to other frame members such that the audio-visual device forms a portion of the frame and maintains other frame members in a spaced-apart relationship. In some embodiments, the frame at least partially defines a riding space, and the audio-visual device is configured to be activated by a child seated within the riding space.

Abstract: The present invention relates to an operation arrangement, particularly to an operation arrangement for a twist vehicle having a sliding slot located on an end portion of an driving frame, a pivot shaft located opposite to the sliding slot, a sliding shaft with one end sliding freely along the sliding slot and another end being connected to a rocking arm, a steering shaft being connected directly and perpendicularly to the rocking arm and operated by a steering wheel. As a result, the steering wheel for the twist vehicle can be extended backwardly towards the rear portion of the operating wheels, close to the user's operation position. This arrangement can improve ease of operation by moving the steering wheel towards the user and also maintain better stability by extending the length of the wheelbase and effectively causing the center of gravity to be shifted toward the idle wheel axle.

Abstract: The disclosure teaches a flywheel power unit that can be inserted into a variety of machines. The standardization of the power unit means that the more expensive gearing, clutch and flywheel components do not have to be duplicated in each human powered machine. Standard bicycle gearing components can be assembled with a modified clutch for a typical motorcycle to create an inexpensive human powered flywheel power unit. As the user pedals, power is stored in the flywheel. The flywheel axle is connected to a transmission transfer gear that turns a transmission input gear for a transmission with multiple gears in a gearing ratio of 10:1 to 0.8:1 (which is typical for a motorcycle transmission.). A transmission input gear and the transmission transfer gear are approximately a 1:1 gearing ratio. A transmission output gear is attached to the transmission that provides power output from the flywheel only when a clutch within the transmission in engaged.

Abstract: The two-wheeler in the form of a dandy horse is propelled by the user by pushing (walking) with his or her feet on the pavement. The dandy horse having a frame (1), a front and a back wheel (3, 4) rotationally mounted therein, a saddle (5) supported by the frame (1) and handlebars (6) supported on the frame (1) for the front wheel (3).

Abstract: A folding bicycle includes a folding mechanism that permits the folding bicycle in its extended state to be folded at an intermediate region between a front wheel and a rear wheel. The folding bicycle is folded by the folding mechanism such that the front wheel is brought to a position at one side of the rear wheel. An axle shift mechanism permits a axle of the rear wheel to be shifted to a position toward the intermediate region. A chain-holding mechanism holds a sprocket chain at a predetermined position when the axle is shifted to the position toward the intermediate region by the axle shift mechanism, to thereby release engagement between a rear wheel-side sprocket and the sprocket chain.

Abstract: A housing (2) for an electronic control unit for use aboard a bicycle and a battery container (3) for powering electrical devices fitted aboard, are provided with quick coupling means (6, 10), that, when coupled, also provide the electrical connection between the batteries and the control unit.

Abstract: Embodiments of a human-powered bumper car are shown and described, each embodiment allowing the occupant of the car to power the car's movement on a surface with his/her feet. Preferably, no motor, fuel, electricity, or pedal mechanism are needed, and no moving parts are needed except for the wheel assemblies and a seat belt. The bottom of the car has an opening which allows the occupant's feet to reach through the car to the ground. The bumper of the car encircles the car and is typically raised up slightly above the elevation of the driver's seat. The resulting distribution of mass of the car and its occupant results in a safe and fun bumper car that is not prone to leaving its stable, horizontal orientation.

Abstract: The present apparatus consists of a frame with a tubular structure, made of the following elements: a number of vertical studs supporting atop cushioned member of a nearly circular shape, the studs rest on a lower frame component having the same bowed shape and a number of casters with braking devices. The frame is selectively completed by a bow-shaped component also cushioned and with fastening means at it sends to allow mounting to the cushioned member. The apparatus also includes a removable an d interchangeable square-shaped seat and a cross-shaped seat having detachable fastening elements, respectively, in relation to ring-shaped pieces in the studs. A flexible and non-extensible band is also provided to be attached to the rings and to surround the body of the user.

Abstract: A transmission wherein power is transmitted between a camshaft and a rotating cylinder block through a pair of pistons reciprocally and slidably disposed within a pair of adjacent cylinders in the cylinder block. In one mode of operation, the transmission provides a direction connection between the camshaft and the cylinder block. In this mode of operation, the pistons are prevented from moving relative to the cylinder block and accordingly rotate therewith, and the camshaft and the cylinder block rotate at the same velocity. In a second mode of operation, the relative speeds of the camshaft and the cylinder block are varied with respect to one another, and the pistons are driven in reciprocating movement 180.degree. out of phase with one another by a pair of cams disposed eccentrically on the camshaft and fixed thereto.

Abstract: This disclosure pertains to a one wheeled vehicle rotatably affixed to a yoke. One arm of the yoke is provided with a stationary foot rest. The other arm of the yoke contains a rack which when reciprocated operates a gear train causing the wheel to rotate. A platform is secured to the uppermost portions of the rack and is biased upwardly by a spring urging the rack in an uppermost position. A pole extends upwardly from the yoke providing steering control to the apparatus and a balancing aid to the user thereof.
