<p>The invention relates to devices intended for conversion of human muscular force into the rotational movement of mechanisms, in particular to the construction of bicycles.The bicycle with oscillating lever comprises a frame with a guide column, on which is installed a guide (6) with a fork (5), installed on the shaft (25) of the front wheel. The frame consists of a rod (1), installed obliquely with an end, made branched, on the shaft (3) of the rear drive wheel, and of an oscillating lever (8), fixed by an axis (9) in one of the holes (7), made in the rod (1). On the rod (1) in the region of branching are fixed two rests (10) for the cyclist's feet and the lower end of a shock damper (11), on the upper end of which is fixed the upper arm of the oscillating lever (8), on which is mounted a T-shaped saddle (12). To the saddle (12) are fixed two traction belts. On the upper and lower arms of the oscillating lever (8) are fixed drive cables (15, 16), the opposite ends of which are fixed on pulleys (18) with the possibility of cable winding thereon. The pulleys (18) are provided with return springs in the form of a spiral and are installed on the shaft (3) of the drive wheel, on both sides of its hub, and engage unidirectionally with the hub. The bicycle may be equipped with a mechanism for regulating the arm of the oscillating lever (8).</p> |
