Definitions

  • the object of the invention is a wheeled vehicle, in particular a wheeled vehicle with mechanical propulsion using the rocking motion of a drive column, useful for moving people.
  • the bicycle is one of the basic wheeled vehicles for moving people using muscle power.
  • a typical bicycle has a frame with a front and rear wheel. Handlebars are embedded in the frame and are used to turn the front wheel.
  • the bicycle is propelled by the muscular power of the rider's legs using a crank mechanism, from which the propulsion is transmitted via an endless link, in particular a chain link, to the rear wheel.
  • WO 2019/184644 discloses a bicycle comprising a front wheel, a rear wheel, handlebars, a pedal, a frame, a connecting rod, a rocking column, a saddle and a gear mechanism for tran smitting the swinging force of the rocking column to the rear wheel assembly.
  • the pedal is pivotally mounted at the lower end of the centre of the frame, the rocking column and the pedal are hinged to the two ends of the connecting rod, the saddle is attached to the hinged end of the connecting rod of the rocking column, and one end of the rocking column, which is far from the saddle, is hinged to the front end of the frame and connected by gearing to the rear wheel assembly through the gear mechanism.
  • the movement of the rider's body weight allows the bike to be propelled.
  • a bicycle is known from the description of US 5042828, in which the rear driving wheel axle is journaled in a yoke at one end of the elongate frame and the front steerable wheel is mounted at the other end of the frame.
  • a rocking column is pivotally mounted on the frame for rotation around an axle which is concentric with the driving wheel axle, a backed seat being saddle mounted at the other end of the column.
  • the bicycle includes a mechanism for converting the speed of the column into the speed of the driving wheel, with the high speed component of the concentric speed converting mechanism being connected to the axle and the low speed component coupled to it by a gearing being connected to the rocking column.
  • Polish patent description PL 221914 B presents a muscle-powered vehicle, the user of which assumes a standing position and propulsion is carried out using the hands.
  • the vehicle contains two driving wheels, inside which independent mechanisms are attached, converting the rocking motion of the lever into unidirectional rotary motion of the driving wheel axles, with at least one passive wheel, the attachment of which enables rotation about a vertical axle, and a low-slung platform attached directly to the housing of the mechanisms.
  • the single propulsion mechanism comprises a central axle, on which two gearwheels equipped with overrunning clutches are mounted, together with a lever-operated ring with a pair of gearwheels thereto attached, the first outer axle with two gearwheels mounted thereon, and the second outer axle with two further gearwheels mounted thereon.
  • the whole is interconnected in such a way that when the inner gearwheel mounted on the lever- operated ring drives the first gearwheel mounted on the first outer axle and further through the second gearwheel mounted on this axle drives the first gearwheel mounted on the central axle, the second external gearwheel mounted on the same ring drives the first gearwheel mounted on the second outer axle and accordingly through the second gearwheel mounted on this axle drives the second gearwheel mounted on the central axle.
  • the two gearwheels located on the central axle always rotate in opposite directions, with the result that when one of these gearwheels, using the overrunning clutch principle, transmits the propulsion from the hand lever to the central axle and further to the driving wheel, the other gearwheel rotates freely.
  • the aim of the invention is to develop a wheeled vehicle design which, while providing the typical advantages of a bicycle, such as a reasonably fast and healthy means of locomotion, will furthermore enable the rider's muscles other than the leg muscles, in particular the skeletal muscles in the upper body, to be worked out and kept in shape.

  • the rocking column is connected to the main gearwheel by a set of gearwheels.
  • the component for bracing is understood to be that which allows the rocking column to be attached to the rider's hips or settling the rider’s hips in it, so that the rocking motion of the column is made possible by alternate forward and backward movements of the rider's hips.
  • the rider performs a reciprocating movement with the hips while simultaneously clasping onto the fixed points, i.e. the handlebars and the footrests, with the legs and hands.
  • This movement of the rider results in a rocking motion of the column, which propels the vehicle.
  • both the forward and backward movement of the hips translates into propulsion, many of the muscles of the rider's upper body are involved in the movement, particularly the skeletal muscles, which enables the rider's spine to remain in good condition.

  • the third gearwheel is rigidly connected to the second gearwheel, and the first gearwheel is further meshed with the fifth gearwheel, which is seated on an axis of rotation fixed to the frame component.
  • the sixth gearwheel rigidly connected to the fifth gearwheel, is mounted on this axle of rotation, this sixth gearwheel being meshed with the seventh gearwheel, freely rotating rel ative to the rocking column only in the same direction as the fourth gearwheel.
  • the first gearwheel , the fourth gearwheel and the seventh gearwheel rotate about the main axle of the propulsion mechanism.
  • the first gearwheel has an internal toothing and the fourth gearwheel and the seventh gearwheel rotate freely only in the direction opposite to the direction of rotation of the main gearwheel.
  • the first gearwheel has an external toothing and the fourth gearwheel and the seventh gearwheel rotate freely only in the direction of rotation of the main gearwheel.
  • the bracing component takes the form of a rider's seat with the backrest and the front rest facing upward.
  • the wheeled vehicle comprises a propulsion mechanism that allows the vehicle to be driven by both a forward movement of the column and a rearward movement.
  • the mechanism is based on two gearwheels spinning in one direction only and four other gearwheels.
  • the mechanism has a compact design, as in practice it can fit into a cylinder with a diameter of about 20 centimetres, i.e. it will not exceed the diameter of the main gearwheel.
  • This design of the propulsion mechanism it is possible for the rider to control the speed of the vehicle on an ongoing basis by selecting the rocking range of the rocking column.
  • the proposed design of the bracing component is convenient and safe, as it provides the possibility for the rider to be seated while moving, and furthermore, in the event of a tip-over, the rider is not tied to the column.

Abstract

L'invention concerne un véhicule à roues équipé d'un cadre (5) doté d'une roue avant pivotante (1) dirigée par un guidon (3) et une roue arrière (4). Le cadre (5) comporte des repose-pieds (7) destinés aux pieds du conducteur sur ses deux côtés latéraux. De plus, le véhicule est équipé d'un mécanisme de propulsion (8) doté d'une colonne basculante (9), qui, à son extrémité supérieure libre, est pourvue d'un appui de hanche destinée au conducteur. Le mécanisme de propulsion (8) comprend l'axe principal (10) intégré dans le cadre (5), autour duquel la colonne basculante (9) tourne et sur lequel la roue dentée principale (11) est fixée, reliée par une liaison d'entraînement sans fin au pignon de roue arrière (4). La colonne basculante (9) est reliée à la roue dentée principale (11) par l'intermédiaire d'un ensemble de roues dentées. Des mouvements alternatifs vers l'avant et vers l'arrière des hanches du conducteur se traduisent en un mouvement de balancement de la colonne (9) et propulsent par conséquent la roue arrière (4) du véhicule.
