Abstract

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to high-speed bicycles. A speed bike is propelled by reciprocating movements of the legs, torso and arms. The bicycle contains a lounger with support platforms for the torso, a frame with an intermediate axle with curled or spirally curled pulleys, traction elements, rear running and steering wheels. The lounger is made in the form of a double-console beam, pivotally connected to the frame and equipped with a tie-down belt and a waist collar. The traction elements are fixed on the beam consoles and are kinematically connected to the running wheel.

EFFECT: simplification of cycling is achieved.

Description

The invention relates to cycling equipment used in everyday life, sports. It can be used as a simulator, a drive for various devices, for example, muscle power generation.

Known designs of special high-speed bicycles involving in the process of movement of all major muscle groups of the user. They are carriage, lever, combined. Known "Folding multifunctional muscle walker" patent RU No. 2757796, publication date 10/25/2021, on which the user moves while lying on a sunbed upside down.

Known "Method of using human muscular energy" patent RU No. 2752105, date of publication and registration 07/20/2021, and bicycle designs based on it are known. When using them, the air resistance is high, which reduces the energy efficiency, especially at high speeds. Movement speed is not enough.

The aim of the invention is to improve aerodynamics and, as a result, speed performance. Reduction of specific labor costs.

The bicycle differs in that its lounger is made in the form of a double-console beam and is hinged to the frame. It has a tie-down strap for pressing the user's upper torso against the support pad of the beam, and is provided with a belt clip for compressing the user's belt and creating a stop for the forces generated by the legs, by means of a flexible cord. We get, as it were, a “lying” swing. The front traction element (rod) of the beam transfers the force created by the back muscles and the extension of the user's arms to the intermediate axle, equipped with curled or spirally curled pulleys, and then to the running wheel. Curled or helically wound pulleys smoothly increase the gear ratio of the drive and harmonize the process with the physiological characteristics of a person (this is described in more detail in the prototype). The rear traction element is equipped with a recuperation mechanism, whereby potential energy is accumulated from the raised head and the front part of the body and the effort of bending the arms and partially the abdominal muscles.

Thus, the user gets the opportunity to concentrate on the running wheel the energy maximum (leg extension + back extension + arm extension + recovery increase) and with several working strokes, bringing the speed to the required level - to rest, taking an almost perfectly streamlined horizontal position. Further, including certain muscle groups in the work, maintain the necessary speed, optimizing the aerodynamic resistance. The implementation of the distinguishing features achieves the indicated technical result and can make it possible to achieve speeds unthinkable for the classics.

Figure 1 and figure 2 shows a high-speed bike with a silhouette of the user in two boundary positions.

Figure 1 and figure 2 shows an embodiment of a speed bike. The bicycle bed is represented by a double-console beam 1 connected to the frame by a hinge (not indicated) and contains a seat belt 2, a waist collar 3, which, using a cord 4, creates a support (stop) for efforts from the legs. The lounger is equipped with a headrest 5 for periodic rest of the neck muscles as needed. The front traction element 6 passes through the swivel pulley 7 and is connected to the coiled pulley 8 on the intermediate axle 9 fixed to the frame 10. The ratchets and return cords of the coiled pulleys and the road wheel pulleys are not shown. To transfer forces from the intermediate axle to the road wheel, a thrust 12 serves. The accumulative elastic band 17 is placed in the body of the frame 10. Rotary pulley 18. Pedal block 19 is connected to the foot rod 20 and has a guide 21 with side-mounted rollers.

Operating procedure. The user, having installed the beam of the lounger between the legs with the upper position of the front of the beam, puts on a belt clamp and, placing the torso on the beam, fastens the belt. He fixes his hands on the steering wheel, inserts one leg in a half-bent position into the pedal block and, with a certain inclination of the bicycle towards himself, pushes off with the other leg from the ground one or several times to obtain the initial speed. Inserts the jogging foot into its pedal block in a half-bent position already in motion. Further, the user is free in subsequent actions depending on the circumstances, for example, the state of the track, the goal set, the state of individual muscle groups, etc. Since the design of the bicycle allows the legs to support the walking mode autonomously, the user can use only them for movement, with arms extended or half-bent. However, the bike is not in vain called high-speed and the user can enjoy it. Namely, by simultaneously bending the legs and arms to the limit, assuming the “fetal position”, while connecting the recuperation mechanism, the user thereby assumes the position for the “quick start”. Further, simultaneously extending the legs and arms, including the muscles of the back and shoulders, receiving additional recuperation energy on the beam, the user concentrates his energy “muscle maximum” on the running wheel. The user makes several such strokes and, having reached the desired speed, transfers the body to a position of almost perfect streamlining, that is, to a horizontal position and spends some time in this position in the "high-speed" rest mode, etc.

A high-speed bike allows you to reach speeds that are inaccessible on the usual "classic", as well as on analogues. In this case, the specific energy consumption is significantly reduced. It is easy to transform a bicycle into a muscle-electric one, for example, by replacing the steering wheel with a motor-wheel, etc. Allows you to open a new direction in the development of bicycle technology.
