(57) Abstract:The invention relates to vehicles, in particular for vehicles with pedal mechanism driven by muscular power. The rod contains the main cylinder, mounted on the leading axis of a pedal mechanism, a rod with a blind hole to accommodate a spring-loaded rod, complete head pedals. The rod and the rod is made of sliding in the axial direction. The rod is supplied with an adapter and nut for adjusting the axial movement of the rod. In the rod threaded hole for screwing the adapter. Spring mounted on the end portion of the rod to lock it in one of the nuts. The invention provides for adjustment of the length of rods depending on the leg length of the driver. 1 Il. The invention relates to vehicles, in particular for vehicles with pedal mechanism, driven by the muscular force of the person's feet /paws animal/.When using the known pedal mechanism, the force is transferred legs alternately only in the anterior half of the circle stroke of the pedal in the second half of the circle have idle pedal.However, biomechanical ago mechanism /see Aruin A. S., Zatsiorsky C. M. "Ergonomic biomechanics". M. "Engineering". 1989 S. 52/.It is now established that the force of the legs, for example, the cyclist, the least efficient in the moment when the rods pass through the vertical position of the dead point and is most effective immediately after passing the dead point when the movement of the legs down.Given this fact, the experts of the American company "Durham bycicle" /Los Angeles/ installed on the bike elliptical leading asterisk, linking its greater axis with the position of the connecting rod that allows rod to move faster dead point and continue to remain in the "strong" position. This solution cyclist, less tired /see Machine Design N 3, 1974/.According to the Leningrad newspaper "Smena" N 166 from 21.07.87, in the article "How to become Edison" C. 2 the effect of the Bicycle transmission when using an elliptical sprocket is increased by fifteen percent.Presented by Bulgarian researchers comparative chart clearly recorded in a more gradual change of torque and perceived leg effort when using the elliptical sprocket /see log for "Modeler-construct the Thun, made in a single piece, although the pedal mechanism is used much more widely, for example with a conical gear drive or even directly mounted on the propeller /rotor/ water bike /see Bogdanov, C. C., Popova S. N. "The story of ordinary things." M "Pedagogy Press, 1992, S. 140, 141/.The current original bike, made in Japan, where the pedal mechanism through the bevel gear rotates the rear wheel (see the newspaper "socialist industry" from 19.11.1989, figure called "disbelief"/.In these cases, the use of asterisks excluded.Famous rod that contains a master cylinder mounted on the leading axis of a pedal mechanism, a rod with a blind hole to accommodate a spring-loaded rod, complete head pedal, the rod and the rod is made of sliding in the axial direction of /DE, N 4114649, B 62 M 1/02 19.12.91/.The purpose of the invention is included, taking into account the biomechanical characteristics of lower limb of a person, to expand the scope of application of the rod regardless of the use of a pedal drive.Essential features of the invention are the two threaded connection details;
taken into account ergonomic biomechanics;
Pets adjustable length connecting rods taking into account the anthropometric characteristics of the driver;
when the landing of the driver on the adult bike, the pedal drops below 22.5 mm;
expanding the use of a rod.The drawing shows a section of the rod with telescopic rod and two heads.The rod contains the main head 1 mounted on the leading axis of a pedal mechanism, the rod 2 with a blind hole to accommodate the rod 3, the compression spring 4 and the screw hole for screwing the adapter 5, which has a keyway 6 /mobile connection/.The rod has a round cross-section and a tapered end portion on which is mounted a spring 4, a locking nut 7. The head 8 of the pedal rod ends 3, which has a threaded hole for attaching pedals. The alignment of the heads 1 and 8 is set using the adjustable strip 9. The axial displacement of the rod 3 is regulated by the nuts 7 and 10.The principle of operation of a rod.When using a pedal mechanism, the force is transferred alternately feet. However, with the passage of pedals and heads pedal 8 through the vertical axis of the leg Negruzzi out of the dead point and to continue in the long version of "strong" position.At the bottom of the pedal position decreases the effort of the legs and the compression spring 4 returns the rod 3 to its original position. And the foot pedal on a short rod in idle mode. The rod that contains a master cylinder mounted on the leading axis of a pedal mechanism, a rod with a blind hole to accommodate a spring-loaded rod, complete head pedal, the rod and the rod is made of sliding in the axial direction, characterized in that it is equipped with an adapter and nut for adjusting the axial movement of the rod, and the rod threaded hole for screwing the adapter, the spring mounted on the end portion of the rod to lock it in one of the nuts.
SUBSTANCE: pedals are supplied with devices fastening footwear and are installed on cranks with possibility to automatically change crank length. Pedal frame (1) contains rectangular horizontal plate (2) having on its upper surface devices (5, 6) fastening bicyclist footwear and girdle (3) on one of its longitudinal edges with pedal axle (4) secured on crank. Plate (2) is connected with girdle (3) so that its upper surface is located below pedal axle (4) at distance (a) and axis (7) of footwear support on plate (2) of pedal located in frontal plane crossing bicyclist metatarsus of hallux when bicyclist revolves pedal is placed in front of pedal axle (4) at distance (b) so that axis (7) of footwear support circumscribes circle with centre (O') and radius (r') displaced below at distance (a) and at distance (b) forward in respect of circle with centre (O) circumscribed by pedal axle (4), where (O) is axis of carriage unit with radius (r).
EFFECT: acceleration of dead points passing and increase of torque.

SUBSTANCE: invention relates to bicycles with reciprocating foot levers that make pedals move as in walking or running. Proposed drive comprises swinging supports 16 and levers 7 fitted via ratchets 6 on crosswise drive shaft 3, gear with drive sprocket coupled via chain with driven sprocket fitted on drive wheel axle. Swinging levers 7 incorporates top and bottom hinges 15, 24. Bottom hinges 15 allow bicyclist to bend and straighten knees in pedaling supports 16. Top hinges 24 reduce air drag by allowing crosswise drive shaft 3 to go down, as well as transparent cabin 1 that features minimum air drag.
EFFECT: reduced air drag, higher comfort.
SUBSTANCE: invention relates to bicycles with pedal drive crank mechanisms that comprises levers of self-adjusting length that run along elliptic trajectory or other noncircular rotational trajectory. Pedal drive with chain or belt transmission comprises pinion frame 1 with its first end coupled with shaft of carriage 2, lever 3 with pedal 4 rigidly fixed with sun gear 5, stationary gear 6 with gear ratio of 2:1 with respect to sun gear 5. Stationary gear 6 is fixed relative to bicycle and coupled with sun gear 5 by chain or belt transmission. Second end of pinion frame 2 is articulated with sun gear 5 at the point shifted from its center while stationary wheel 6 features shape other than circle.
EFFECT: reduced drive forces due to mismatch between passing top dead center and bottom dead center of pedals.
