TH10193B - Two wheeled bicycle - Google Patents

Abstract

A two-wheeled bicycle that is interchangeable between a standard bicycle shape for normal riding and an exercise style where the bicycle is propelled forward by alternating the effect of the saddle stroke. and the effect of the pedal stroke Which the saddle stroke consists of dropping the weight of the rider on the saddle, which moves downwards to drive the crankshaft and bring the 2 pedals, which are in a position together up to the top. and the pedal stroke consists of exerting pressure on both pedals to bring the saddle back up again, in an exercise manner the bicycle is prevented from tripping over power by Arrange in such a way that when pedaling pedals are at the bottom dead center the weight is on top. The saddle is applied to the crank at an angle to the vertical. in order to maintain the forward propulsion And with this arrangement, when the saddle is at the bottom dead center, the pedal is positioned slightly forward of the top dead center to maintain forward propulsion. In an exercise style, pedal pedals may be limited to turning in one direction only by means of a sawtooth gear wheel mechanism. This will prevent the pedals from hitting the rider's shin.

Claims (6)

1.Two-wheel bicycles, whose rotation of the caster can be achieved by the effect of force in the manner alternating with the pedals and the saddle, are characterized in such a way that the saddle (5) and the pedals (4a, 4b). ) Is connected to or can be connected to the crankshaft (6) in such a way that when the crank of the pedals (6a, 6b) and the pedals (4a, 4b) are in the lower dead center position, the Relay between the saddle (5) and the crank of the saddle. (6c) The saddle crank angle (6c) is angled in such a way that the rider's weight is applied to the crank of the reading (6c) to propel the bicycle forward and when the saddle (5) is at the dead center position. Below, the crank of the pedals. (6a, 6b) and the stairs (4a, 4b) are located slightly ahead of the top dead center. 2. Two-wheeled bicycles, as claimed in claim 1, in which the crank mechanism consists of a mechanism (12) for limiting the spin in the forward direction only. 3.Two-wheeled bicycles, as claimed in claim 2, the mechanism for such restriction is a serrated cogwheel mechanism (12). 4. Two-wheeled bicycle, as claimed in claim 2, the mechanism for such restriction is a clutch mechanism. 5. Two-wheeled bicycles as claimed in any of the 2 to 4 claims The mechanism for controlling the rotation can be released. 6.Two-wheel bicycles, according to one of the above claims, are convertible between the characteristics in which the saddle (5) and pedals (4a, 4b) are connected to the crankshaft (6). In general, different positions, so that the bicycle can be driven forward by an alternating force effect on the pedals (4a, 4b) and with the saddle (5) and the normal riding style in the saddle. (5) will be connected. To the bicycle frame (1) and the 2 pedals (4a, 4b) are connected to the crankshaft (6) in different positions so that the bicycle can be driven in a normal way.
