Bearings attached to the leading wheel eccentric and diametrically opposed relative to the axis of the wheel. 2 Il. The invention relates to the field of mechanical engineering and sports, and more specifically to the manufacture of bicycles.Famous bike that contains the frame with the wheel, leading and steering wheel and pedal chain drive, which is its disadvantage (see U.S. patent N 1443887, class B 62 M 1/04, 1923).The closest analogue of the claimed invention is a Bicycle that contains the frame with the wheel, leading and steering wheel and pedal drive with pedals, pivotally connected to the frame (see French patent N 1498970, class B 62 M 1/04, 1967).The technical result of the invention is to simplify the design.This technical result is achieved by the fact that the bike that contains the frame with the wheel, leading and steering wheel and pedal drive with pedals, pivotally connected to the frame, according to the invention of the pedal cover bearings, kachani the ptx2">The invention is illustrated by drawings, where
in Fig. 1 shows a Bicycle;
in Fig. 2 - node setup of pedals.The bike contains a frame with the wheel 1, host 2, and 3 steering wheels, pedals 4 and bearings 5 in the respective pedals.One of the pedals 4, pivotally connected with the frame 1 and are in the upper position when the downward movement as the lever acts on the bearing 5 and turns it due to the eccentricity of the axis of the drive wheel 2, and therefore the wheel itself, in diametrically opposite bearing raises another pedal 4 in the top position and returns it to its working position. Alternate effects pedal cause the rotation of the impeller, and with him and the bike. The bike contains a frame with the wheel, leading and steering wheel and pedal drive with pedals, pivotally connected to the frame, characterized in that the pedal cover the bearings attached to the leading wheel eccentric and diametrically opposed relative to the axis of the wheel.
FIELD: sportive exercisers for working out of main group of muscles, may be used for providing normal general health state of users, as well as for special preparing of sportsmen.
SUBSTANCE: cycle exerciser has base mounted on supports and equipped with axle, on which loading unit is fixed. Loading unit has flexible members and pedals and is made in the form of variable-radius disk-shaped member fixed on axle, and at least one loading member positioned for rotation around base axis and comprising two concentrically arranged outer and inner bushings with outer end surfaces, between which flexible member is located. End surface of outer bushing is adapted for regulating force applied by flexible member. Inner bushing is positioned for displacement in outer bushing equipped with stops for inner bushing. Bushings are provided with axle, on which body of rotation is positioned, said body of rotation being in contact with disk-shaped member. Disk-shaped member is made in the form of ellipse and is composed of two parts, each of which is fixed on axle through plates with fastening members. In order to rotate loading member, base axle is equipped with bushing. Loading member is rigidly connected with bushing by means of special plates. Loading unit is provided with additional disk immovably fixed on base axle and equipped with circumferential openings for fixation of loading unit in predetermined position. Inner surface of outer bushing of loading member is furnished with thread allowing outer bushing outer surface to move with changing of force applied by flexible member.
EFFECT: wider operational capabilities of cycle exerciser by providing changing of kind of action upon user's muscles by increased number of peak loadings per cycle of rotation of pedals, and owing to displacement of position of peak loading during cycle.

FIELD: sportive exercisers for working out main group of muscles, may be used for providing normal general health state of users, as well as for special preparing of sportsmen, as well as in medicine as rehabilitation means during post-traumatic period.
SUBSTANCE: cycle exerciser has base, posts fixed to base, and axle. Pedals are secured on axle by means of connecting rods. Cycle exerciser is further provided with loading unit including flexible members, at least two variable-profile members formed as washers, each of said members changing their position around axis for changing type of loading, and at least two loading members fixed on connecting rods, each of them being made in the form of ball arranged in cylindrical casing, said ball being engageable, at one side, with washer-shaped members and, at other side, with flexible member arranged in casing. Said casing is equipped with supports for ball, and its end part is positioned for regulation of force applied by flexible member. Furthermore, posts and supports may be positioned for rotation around base axis and are provided with fastening members for attachment to washer-shaped member. In order to provide rotation of posts and base, base axle is equipped with bushings. Inner surface of cylindrical casing of loading member is furnished with thread allowing outer bushing outer surface to move with changing of force applied by flexible member. Loading member is provided with insert arranged between ball and flexible member.
EFFECT: wider operational capabilities of cycle exerciser by providing changing type of action upon user's muscles by increased number of peak loadings per cycle of rotation of pedals, and owing to displacement of position of peak loading during cycle, and as well as the possibility of changing force acting upon user's left-hand and right-hand limbs.

SUBSTANCE: device for motor rehabilitation and training contains base, pedal unit, support of pedal unit, back vertical support. Pedal unit contains pedals and connecting rods, pedals being made in form of elongated support sites for patient's upper and lower extremities, each of which is with one side hingedly fixed on connecting rod, and the other side is connected with movable bar, which is hingedly connected with horizontal bar. Bar is fixed on vertical support, connecting rods of pedal unit are made with possibility to change connecting rod length.
EFFECT: application of claimed invention allows to extend possibilities of effecting muscles of musculoskeletal apparatus with simultaneous reduction of size and increase of convenience in application.
FIELD: medicine, sport.
SUBSTANCE: stationary bicycle comprises a frame with feet pedals mounted on the frame, as well as a seat with an inflatable chamber; the user can train the cardiovascular system, as well as the main abdominals and muscles of the back. A sensor can be used to measure the compression level of the inflatable chamber when an individual sits on the inflatable seat with a properly adjustable inner pressure of the chamber. The frame can have two sections detachable so that one of the sections and the inflatable seat can be used as a seat kit when detached.
EFFECT: structural improvement.

SUBSTANCE: in null-gravity condition disrupt of eupraxia occurs, cardiovascular system weakens, metabolic disorder, weight absence leads to muscle atrophy, loss of calcium and bones strength reduction. The most acceptable method to withstand said disorders is movement and physical activity. Biokinetic training device for strengthening human supporting-motor system under null-gravity condition allows to some extent simulate gravity, compensate lack of movements and maintain normal coordination of movements the musculoskeletal system. Foundation of biokinetic training device for strengthening human supporting-motor system under null-gravity condition is made up of: biokinetic module, consisting of kinetically united hand supports and foot pedals, which ensures coordination of movements of musculoskeletal system and involves in the development of almost all the major muscle groups of body; and a device to simulate Earth's gravity, consisting of lining for the back and ties. Use of biokinetic training is considered viable to strengthen human supporting-motor system under null-gravity condition both separately and in complex in combination with a treadmill and a special space simulator ARED.
EFFECT: biokinetic training device for strengthening human supporting-motor system under null-gravity condition does not contain complex elements, it is easy to manufacture, does not take up much space, is convenient and effective in application.
