Abstract:
Various embodiments of a side-by-side flexible twin bicycle are disclosed. In at least one embodiment, the side-by-side flexible twin bicycle includes two bicycles joined together sideby-side by means of a plurality of interconnecting pivoted link bars. One or more driver riders may simultaneously or independently operate said side-by-side flexible twin bicycle. In at least one embodiment, the side-by-side flexible twin bicycle may be configured employing different size bicycles, in-line multi-rider tandem bicycles, recumbent bicycles, mountain bicycles, and motorcycles of various types. These embodiments provide the vertical stability of a four-wheel vehicle while retaining the ability to lean into turns and ride over irregular surfaces affording for each of the riders the handling, ride and •feel similar to that of a single conventional bicycle.
Abstract:
An adapter for interconnecting two bicycles in a side-by-side configuration, wherein the adapter comprises a plurality of articulating joints to permit the joined bicycles to articulate or tilt in coordination while being ridden. The present invention further includes various tilting mechanisms and braking systems to achieve and maintain desired tilted positions of the joined or interconnected bicycles.
Abstract:
A frame (2, 20, 200) for a cycling vehicle (1, 10, 100) of the type comprising a front steering wheel (3a), a rear drive wheel (3b, 3b', 3b"), a first front pedalling position (4a) and a second rear pedalling position (4b), each including a seat (5a, 5b) and a crankset (6a, 6b), wherein said first (4a) and second (4b) pedalling positions are offset from each other relative to a direction of forward motion of the vehicle (1, 10, 100).
Abstract:
The present invention relates to a tandem bicycle having a front wheel and a rear wheel, a main frame which separates the front wheel and the rear wheel, and a pair of saddles supported by the main frame. A characterizing feature of the present invention is that it comprises: a main rotational shaft provided in such a way as to be able to rotate on the main frame; a pair of main pedals for making the main rotational shaft rotate; a rear-wheel shaft which is provided in such a way as to be able to rotate on the main frame, and which has the rear wheel mounted on it; a main power-transmission part for transmitting, to the rear-wheel shaft, a rotational force generated at the main rotational shaft; an auxiliary rotational shaft which is positioned between the main rotational shaft and the rear-wheel shaft, and which is provided in such a way as to be able to rotate on the main frame; a pair of auxiliary pedals for making the auxiliary rotational shaft rotate; an auxiliary drive sprocket located on the auxiliary rotational shaft; an auxiliary driven sprocket located on the rear-wheel shaft; an auxiliary chain for transmitting power, which links the auxiliary drive sprocket and the auxiliary driven sprocket with each other; and a one-way clutch which is provided between the auxiliary driven sprocket and the rear-wheel shaft, and which imposes a break in such a way that rotational force from the rear-wheel shaft is not transmitted to the auxiliary driven sprocket. In this way, not only can the machine move as a rider sitting at the rear rotates the pedals as they themselves desire, but also the enjoyment to be had from riding on a bicycle can be multiplied. Additionally, two riders can sit back to back, and can move safely while ascertaining conditions to front and rear.
