A small man-powered bump car that requires only human muscle as its energy source. Extended play, either individually or in a group, can be enjoyed by riders of the bump car in a relatively level ground. Riders are safely enclosed in a body panel while engaging in a healthy sport.

A twist vehicle which includes a rear operation system wherein the steering unit of twist vehicle is mounted in a relatively rear position with respect to the vehicle frame, such that a rider can drive the twist vehicle without leaning forwardly and uncomfortably. The function is achieved by connecting the steering unit by a driving member which is further mechanically connected to a driven member by a transmission belt, so that when clockwise and anti-clockwise movements are subsequently impart...

A manpower-driven cycle comprising a driving mechanism transforming a reciprocating motion of a handle into a rotary motion of a rear wheel. A steering and maintaining device comprises a telescopic actuating system with articulated tubes along parallelograms deformable in the direction of a longitudinal supporting rod. A pair of toothed meshing gears are linked by connecting rods to the telescopic actuating system to permanently maintain the handle axis in a vertical median plane passing through...

An exercise vehicle is provided with excellent stability in turns and realistic rowing motion for propulsion. An operator sits on a moveable seat with his feet straddling a drive member which is moved in a forward and backward plane for propulsion, while grasping steering handles at the end of the drive member. A front axle is pivoted between a pair of inclined planes against which the axle bears, pushing down the frame during a turn to induce a sideways cant of the frame when turning. The devic...

A tricycle which may be propelled by the arms of the rider as he is supported thereon in a prone position. The forward or drive wheel is driven by the rider as he grasps a pair of hand-grips which respectively are rotatably attached to a pair of opposing crank members. A typical coaster-brake couples the crank members to the drive wheel to enable the rider to cease turning the crank members for coasting, steering, and braking purposes. A slide-bar is included which is established in part by one ...

A mounting assembly on a hand cycle for the shift and brake handles which includes a collar clamp carried on the end of the front post for detachably connecting with an elongated support member having opposite ends. The clamp member is releasably coupled to the midsection of the support member and the rear-most end of the support member carries a bearing assembly for operably mounting a crank handle with hand pedals. The hand crank further includes sprocket gearing which rotates with the hand cr...

A skateboard which can be propelled with both hands through manpowered propelling devices, and which has been designed in such a manner that a rider can both propel and steer from a body position favorable for high performance, is disclosed.

There is disclosed a wheeled type ridable amusement device adapted to be driven and steered by man power, comprising a frame constructed of a metal or synthetic resin pipe shaped into an annular form, two opposed main wheels mutually independently and rotatably mounted on opposite sides of the frame, handles for independently manually driving the respective main wheels for rotation, a seat with its backrest secured to the rear region of the frame, a footrest disposed in the front region of the f...

A mobile vertical supporting apparatus for a child having an elongated support frame, an elongated front support leg and an elongated rear support leg is shown. The elongated support frame, front support leg and rear support leg are operatively coupled together and support an axle having two opposed wheel support ends operatively attached thereto. A foot support is operatively attached to and extends between the elongated support frame and a lower portion of the elongated rear support leg and is...

The invention provides a propulsion, braking and anti-rollback control assembly for use in manually propelled vehicles such as wheelchairs. In one embodiment, the invention provides a wheelchair with a control lever assembly and related force conveyance connecter that propel, brake and steer the wheelchair in a mechanically advantageous way while minimizing rollback. A seat-activated auxiliary braking system is also provided. Additionally, the invention provides a selective anti-rollback disenga...
