Фиг.З - элемент для фиксации, закрепленный на рычаге (увеличено). Fig.Z - element for fixing, mounted on a lever (enlarged).
Устройство содержит кулачок (1), закрепленный на оси вращения шатуна (2), подшипник (3), выполненный с возможностью взаимодействия внешнего кольца с кулачком (1), и пружину (4), первый конец которой соединен с крепежным элементом (5), зафиксированным на нижнем пере (6) рамы. Подшипник (3) установлен в корпусе (7) и закрыт пластиной (8). Корпус (7) с подшипником (3) и закрывающей пластиной (8) закреплены на рычаге (9), один конец которого соединен со вторым концом пружины (4), а другой конец шарнирно соединен с крепежным элементом (10), зафиксированным на нижней трубе (11) рамы. Устройство дополнительно содержит переключатель (12), шарнирно закрепленный на крепежном элементе (13), зафиксированном на подседельной трубе (14) рамы, и удерживающую пружину (15), закрепленную одним концом на крепежном элементе (13), зафиксированном на подседельной трубе (14) рамы, а другим - на переключателе (12). Кулачок (1) закреплен на шатуне (2) при помощи крепежного элемента (17). Крепежные элементы (10), (13) и (17) зафиксированы посредством хомутов (18). Переключатель (12) выполнен в виде рычага, на один конец которого выполнен в виде крюкообразного элемента (19), посредством которого переключатель (12) зацепляется с элементом (16) для фиксации, закрепленным на рычаге (9). На другом конце переключатель (12) содержит лапку (20) для удобства перевода переключателя из отключенного положения во включенное.
Устройство работает следующим образом. The device comprises a cam (1) mounted on the axis of rotation of the connecting rod (2), a bearing (3) made with the possibility of interaction of the outer ring with the cam (1), and a spring (4), the first end of which is connected to the fastening element (5), fixed on the lower feather (6) of the frame. The bearing (3) is installed in the housing (7) and is closed by a plate (8). A housing (7) with a bearing (3) and a cover plate (8) is mounted on a lever (9), one end of which is connected to the second end of the spring (4), and the other end is pivotally connected to a fastener (10) fixed to the lower pipe (11) frames. The device further comprises a switch (12) pivotally mounted on a fastener (13) fixed to the seatpost tube (14) of the frame, and a holding spring (15) fixed at one end to a fastener (13) fixed on the seatpost (14) frame, and the other on the switch (12). The cam (1) is secured to the connecting rod (2) using a fastener (17). Fixing elements (10), (13) and (17) are fixed by means of clamps (18). The switch (12) is made in the form of a lever, at one end of which is made in the form of a hook-shaped element (19), by means of which the switch (12) is engaged with the element (16) for fixing, mounted on the lever (9). At the other end, the switch (12) contains a tab (20) for the convenience of moving the switch from the off position to the on position. The device operates as follows.
Когда переключатель (12) находится в отключенном положении механическое устройство оказывает давление на ось вращения педалей велосипеда (рабочее положении). Подпружиненный рычаг (9), вместе с закрепленными на нем корпусом (7) с подшипником (3) и закрывающей пластиной (8), давит усилием сжатия пружины (4) через внешнее кольцо подшипника на кулачок (1). В результате чего устройство делает неравномерным вращение педалей. В согнутом под углом 90° положении ноги велосипедиста нагрузка снимается с ноги велосипедиста. Нагрузка перераспределяется на ногу в более развёрнутом положении. Механическое устройство эффективно работает только на средней и высокой скорости вращения педалей велосипеда. При включении переключателя (12) давление механического устройства на ось вращения прекращается (нерабочее положение). When the switch (12) is in the off position, the mechanical device exerts pressure on the axis of rotation of the pedals of the bicycle (working position). The spring-loaded lever (9), together with the housing (7) attached to it with the bearing (3) and the closing plate (8), presses the compression force of the spring (4) through the outer bearing ring onto the cam (1). As a result, the device makes the rotation of the pedals uneven. In the position of the cyclist's leg bent at an angle of 90 °, the load is removed from the cyclist's leg. The load is redistributed to the leg in a more deployed position. The mechanical device only works efficiently at medium and high speed pedals of the bicycle. When the switch (12) is turned on, the pressure of the mechanical device on the axis of rotation is stopped (inoperative position).
Предлагаемое устройство обеспечивает снятие нагрузки с ноги велосипедиста в её согнутом под 90° положении и перераспределяет нагрузку на ногу в более развёрнутом положении, что в свою очередь уменьшает усталость, в целом, от процесса вращения педалей велосипеда. Предлагаемое механическое устройство в работающем состоянии задействует верхнюю группу мышц бедра в отличии от обычного механизма велосипеда, который задействует в работе по вращению педалей, в первую очередь, мышцы нижней части бедра. The proposed device provides removal of the load from the cyclist’s leg in its bent position at 90 ° and redistributes the load on the leg in a more extended position, which in turn reduces fatigue, in General, from the process of rotation of the bike’s pedals. The proposed mechanical device in working condition involves the upper thigh muscle group, in contrast to the usual bicycle mechanism, which engages in the work on pedaling, primarily the muscles of the lower thigh.
Таким образом, предлагаемая полезная модель позволяет расширить арсенал технических средств для облегчения вращения педалей велосипеда при средней и высокой скоростях.
Thus, the proposed utility model allows you to expand the arsenal of technical means to facilitate the rotation of the bicycle pedals at medium and high speeds.
