Abstract

1. Велосипед, включающий раму, колеса и привод, содержащий шатун с ведущей звездочкой и рычаг одним концом шарнирно прикрепленный к раме велосипеда, а другим шарнирно к коромыслу с педалью, отличающийся тем, что рычаг одним концом шарнирно соединен с шатуном, а на другом конце его установлена педаль, аналогично установлен еще один рычаг к другому шатуну, причем шарнирные соединения рычагов с шатунами подпружинены между собой и имеют регулируемые элементы, ограничивающие угол поворота рычагов относительно шатунов и элементы зацепления, ограничивающие крайние положения рычагов относительно шатунов, а длины их равны 0,25…0,95 длины штатного шатуна, при этом ось педали в исходном положении не выходят за габариты ее оси в штатном шатуне. ! 2. Велосипед по п.1, отличающийся тем, что регулируемый угол поворота составляет 45…90° и обеспечивается с помощью винта, установленного, например, на головке шарнира шатуна, взаимодействующего с выступом на головке рычага, а ограничительные элементы зацепления шарнира, например, шатуна выполнены в виде паза взаимодействующие с выступами на шарнире рычага. ! 3. Велосипед по п.1, отличающийся тем, что шарнирные соединения подпружинены пружинами растяжения, которые одним концом закреплены на шатуне вблизи оси, а другим на рычаге снабженным рядом отверстий, с которыми взаимодействует другой конец пружины.1. A bicycle including a frame, wheels and a drive, comprising a connecting rod with a drive sprocket and a lever pivotally attached to the bicycle frame at one end and pivotally connected to the rocker arm with a pedal, characterized in that the lever is pivotally connected to the connecting rod at one end and the other end it has a pedal installed, similarly another lever is installed to another connecting rod, and the articulated joints of the levers with connecting rods are spring-loaded with each other and have adjustable elements that limit the angle of rotation of the levers relative to the connecting rods and engagement elements the corresponding extreme positions of the levers relative to the connecting rods, and their lengths are 0.25 ... 0.95 of the length of the standard connecting rod, while the pedal axis in its initial position does not go beyond the dimensions of its axis in the standard connecting rod. ! 2. The bicycle according to claim 1, characterized in that the adjustable angle of rotation is 45 ... 90 ° and is provided with a screw mounted, for example, on the head of the connecting rod hinge, interacting with the protrusion on the lever head, and the limiting elements of the hinge engagement, for example, the connecting rods are made in the form of a groove interacting with the protrusions on the lever hinge. ! 3. The bicycle according to claim 1, characterized in that the articulated joints are spring-loaded with tension springs, which are attached at one end to the connecting rod near the axis and the other at the lever equipped with a series of holes with which the other end of the spring interacts.
