Description
Mecanisme de propulsion pour blcyclette Ort connait des bicyclettes dont 1e m6canisme de propulsion comprend deux longues p6dales oscillant autour d'un axe situd ä 1'arriere du cycle, Feffort exerc6 sur chacune des p6dales 6tant transmis par des bielles ä des roues ä chaine situ6es au-dessus de la roue arriere, les chaines engrenant avec des pi- gnons d'accouplement du moyeu de la roue arriere. Les deux bras de pedales sont relies ä un dispositif ä roues coniques synchronisant leurs mouvements de va-et-vient. Propulsion mechanism for bicycles Ort knows bicycles whose propulsion mechanism comprises two long pedals oscillating around an axis located at the rear of the cycle, the force exerted on each of the pedals being transmitted by connecting rods to chain wheels located at the rear of the cycle. above the rear wheel, the chains meshing with the coupling sprockets of the rear wheel hub. The two pedal arms are connected to a device with bevel wheels synchronizing their reciprocating movements.
Dans un autre m6canisme de propulsion connu, 1e mouvement de va-et-vient de deux courtes p6dales est transform6 en mouvement rotatif d'un arbre soli- daire dune roue ä chaine normale pour 1'entraine- ment de la roue arriere. In another known drive mechanism, the reciprocating motion of two short pedals is transformed into the rotary motion of a shaft integral with a normal chain wheel for driving the rear wheel.
Un autre mecanisme de propulsion pr6voit deux pedales oscillant autour d'un axe situe verticalement en dessous de la selle, chaque pMale 6tant solidaire d'un bras se terminant par un secteur ä 1'extr6mit6 avant duquel est fix6e une chaine de traction trans- mettant son mouvement de va-et-vient ä un pignon d'accouplement ä roue hbre de la roue arriere. Dans une variante de ce m & anisme, 1e mouvement de va- et-vient vertical des p6dales est transform6 en un mouvement de va et-vient horizontal de tiges dentdes engrenant avec des pignons d'accouplement ä roue libre de la roue arriere. Another propulsion mechanism provides for two pedals oscillating around an axis located vertically below the saddle, each pole being attached to an arm ending in a sector at the front end of which is fixed a traction chain transmitting its reciprocating movement to a main wheel coupling pinion of the rear wheel. In a variant of this mechanism, the vertical reciprocating movement of the pedals is transformed into a horizontal reciprocating movement of toothed rods meshing with freewheel coupling sprockets of the rear wheel.
La pr6sente invention, tout en prAentant les avantages du rendement sup6rieur des p6dales oscil- lantes ä grand bras de levier, supprime entierement la transmission de mouvement par chaine ou tiges dent6es, ainsi que 1e dispositif d6railleur. The present invention, while presenting the advantages of the superior efficiency of oscillating pedals with a large lever arm, entirely eliminates the transmission of movement by chain or toothed rods, as well as the derailleur device.
Le mecanisme de propulsion pour bicyclette se- Ion 1'invention est caractdris6 par 1e fait que chaque bras de pMale porte un secteur dentd qui, par Fin- term6diaire d'un train de roues dentees attaque un dispositif d'accouplement ä roue libre morste sur 1e The propulsion mechanism for a bicycle according to the invention is characterized by the fact that each arm of the shaft carries a toothed sector which, via the intermediary of a train of toothed wheels, engages a freewheel coupling device on the 1st

Le dessin annexd montre, ä titre d'exemple, une forme d'execution du mecanisme de propulsion selon 1'invention, ainsi qu'une variante. The attached drawing shows, by way of example, one form of execution of the propulsion mechanism according to the invention, as well as a variant.
La fig. 1 est une vue en 616vation du m6canisme de propulsion, et la fig. 2 en est une vue en plan. fig. 1 is an elevated view of the propulsion mechanism, and FIG. 2 is a plan view.
La fig. 3 est une vue partielle dune variante du train de roues dentdes, la fig. 4 une vue en plan de cette variante. fig. 3 is a partial view of a variant of the set of toothed wheels, FIG. 4 a plan view of this variant.
Le mecanisme de propulsion repr6sent6 sur les fig. 1 et 2 comporte deux bras pedale 1 et 2 oscillant autour d'un axe 3 cdincidant avec Faxe de la roue arriere 4, les plans d'oscillation dtant paralleles au plan du cadre 5. Les extr6mit6s libres des bras 1 et 2 portant les p6dales 6 et 7 peuvent d6crire des arcs de cercle I, a1, II repr6sentds par des traits-points sur la fig. 1. The propulsion mechanism shown in Figs. 1 and 2 comprises two pedal arms 1 and 2 oscillating around an axis 3 cincidant with the axis of the rear wheel 4, the planes of oscillation being parallel to the plane of the frame 5. The free ends of the arms 1 and 2 carrying the pedals 6 and 7 can describe circular arcs I, a1, II represented by dotted lines in FIG. 1.
A la place du moyeu de p6dalier dune bicyclette ordinaire, est dispos6 un moyeu 8 dann lequel tourne une manivelle double comportant un arbre 9 et deux bras 10 et 11 solidaires de celui-ci, 1e bras 11 dtant plus Jong que 1e bras 10. Instead of the bottom bracket hub of an ordinary bicycle, there is a hub 8 in which rotates a double crank comprising a shaft 9 and two arms 10 and 11 integral therewith, the first arm 11 being longer than the first arm 10.
A 1'extr6mit6 du bras 10 est mont6 un galet 12 qui peut couhsser ä Fint6rieur dune ferste 13 prati qu66 dans 1e bras 1. At the end of the arm 10 is mounted a roller 12 which can run inside a hollow 13 provided in the arm 1.
Un galet 14 est mont6 sur 1e bras 1 dans 1e pro longement de la ferste 13.A Fextr6mit6 du bras 11 est mont6 un galet 15 qui peut coulisser ä 1'int6rieur dune ferste 16 pratiqu6e dans 1e bras pMale 2. La fourche 17, 17' presente deux mdplats 18, 18' sur lesquels sont mont6es les roues dentdes pour la trans- mission du mouvement des bras de p6dales. Un pi- gnon dente interchangeable 19 coaxial ä et solidaire en rotation de la roue dentee 20, engrene avec un seeteur dent6 21 bloqu6 Sur le bras de p6dale 1. Le secteur 21 peut coulisser Sur une courte longueur du bras 1 et peut eire bloqu6 Sur ce demier par un dis- positif de blocage 22. La roue dent6e 20 engrene avec une roue interm6diaire 23 et cette derniere avec la denture de 1'accouplement ä roue libre 24 de la roue arri#re. De meme le bras de pMale 2 porte un secteur dente 21' engrenant avec un pignon inter- changeable 19', solidaire en rotation de la roue den- t & 20', celle-ci engrenant avec la roue dent6e inter- mediaire 23', cette derniere engrenant avee la denture 24' de 1'accouplement ä roue libre. A roller 14 is mounted on the arm 1 in the extension of the ferste 13. At the end of the arm 11 is mounted a roller 15 which can slide inside a ferste 16 practiced in the first main arm 2. The fork 17, 17 'has two flats 18, 18' on which are mounted the toothed wheels for the transmission of the movement of the pedal arms. An interchangeable toothed pinion 19 coaxial with and integral in rotation with the toothed wheel 20, meshes with a toothed seator 21 blocked on the pedal arm 1. The sector 21 can slide over a short length of the arm 1 and can be blocked on the latter by a locking device 22. The toothed wheel 20 meshes with an intermediate wheel 23 and the latter with the toothing of the overrunning coupling 24 of the rear wheel. Likewise, the arm of the male 2 carries a toothed sector 21' meshing with an interchangeable pinion 19', integral in rotation with the toothed wheel 20', the latter meshing with the intermediate toothed wheel 23', the latter meshing with the toothing 24' of the overrunning coupling.
Le fonetionnement du m6canisme de propulsion est 1e suivant Lorsqu'on abaisse par exemple la pMale 6 (fig. 1), celle-ci d6crit Farc I, a1, II. Le galet 14 (qui d6crira un arc parallele ä 1'are 11I, a4, IV) appuie Sur le cdt6 du bras de manivelle 10 et amorce le d6placement du galet 12 selon 1'are III, a5, IV dann la fente 12 du bras de pMale 1. The operation of the propulsion mechanism is as follows When the blade 6 is lowered, for example (fig. 1), this describes Farc I, a1, II. The roller 14 (which will describe an arc parallel to the area 11I, a4, IV) presses on the side of the crank arm 10 and initiates the movement of the roller 12 along the area III, a5, IV in the slot 12 of the arm. from pMale 1.
Simuitanement la manivelle 11 solidaire en rota- tion de la manivelle 10, d & rit Farc V, a2, VI et le galet 15, cöulissant dans la fente 16, entraine le bras 2 vers 1e haut, la p6dale 7 d6crivant 1'arc II, a1, I. L'extr6mite de la fente 13 dirig6e vers la pedale 6 et 1'extr6mit6 de la fente 16 dirig6e vers laxe 3 de la roue arriere forment but6es darret pour les galets 12 et 15 respectivement. 0n pourra y pr6voir des tampons amortisseurs de choc, en caoutchouc par exemple. Simultaneously the crank 11 integral in rotation with the crank 10, deflects Farc V, a2, VI and the roller 15, sliding in the slot 16, drives the arm 2 upwards, the pedal 7 describing the arc II , a1, I. The end of the slot 13 directed towards the pedal 6 and the end of the slot 16 directed towards the axle 3 of the rear wheel form stop stops for the rollers 12 and 15 respectively. Shock-absorbing pads, for example made of rubber, can be provided.
Pendant 1e deplacement de la p6dale 6 vers 1e bas c'est-ä-dire suivant Farc I, a1, II, 1e secteur 21 en- grene avee le pignon 19 solidaire en rotation de la roue dent & 20 qui par 1'interm6diaire de la roue dentee 23 fait toumer la roue dentee 24 dans 1e sens contraire ä celui des aiguilles dune montre. La roue dentee 24 6tant solidaire de 1'accouplement ä roue libre (non dessin6) de la roue arriere entraine cette derniere en rotation. Pendant ce temps le bras 2 de la p6dale 7 d6crivant 1'are II, a1, I, 1e seeteur 21' en- traine 1e pignon 19' en rotation dann le sens des aiguilles dune montre, et, par Fintermediaire des roues dent6es 20' et 23', fait tourner la roue dent6e 24' dans le meme sens, Faccouplement avec le moyeu solidaire de la roue 24 travaillant RTI ID="0002.0278" WI="7" HE="3" LX="828" LY="2236"> alors en roue libre. During the movement of the pedal 6 downwards, that is to say along Farc I, a1, II, the sector 21 meshes with the pinion 19 integral in rotation with the toothed wheel & 20 which, through the intermediary of the gear wheel 23 rotates gear wheel 24 counterclockwise. The toothed wheel 24 being integral with the freewheel coupling (not drawing 6) of the rear wheel drives the latter in rotation. During this time the arm 2 of the pedal 7 describing the are II, a1, I, the seator 21' drives the pinion 19' in rotation clockwise, and, through the intermediary of the toothed wheels 20' and 23', rotates the toothed wheel 24' in the same direction, the coupling with the hub integral with the wheel 24 working RTI ID="0002.0278" WI="7" HE="3" LX="828" LY=" 2236"> then coasting.
L'inverse se produit lorsque la pgdale 7 d6crit 1'arc descendant I, a1, 1I, et la pMale 6 Farc ascen- dant II, a1,1, Fentrainement de la roue arriere 4 se faisant alors par la roue dentee 24', la roue dent6e 24 tournant ä vide. The reverse occurs when the pedal 7 describes the descending arc I, a1, 1I, and the pedal 6 Farc ascending II, a1,1, the driving of the rear wheel 4 then being done by the toothed wheel 24 ', the toothed wheel 24 rotating empty.
Äu lieu de faire osciller les bras de p6dale 1 et 2 autour d'un axe commun coincidant avee laxe de la roue arriere, an pourrait faire osciller le bras de p6 dale 1 autour d'un axe cöincidant avec celui de la roue dent6e intermediaire 23 et 1e bras de p6dale 2 autour d'un axe coincidant avec celui de la roue dentee intermediaire 23'. Instead of oscillating the pedal arms 1 and 2 around a common axis coinciding with the axis of the rear wheel, one could oscillate the pedal arm 1 around an axis coinciding with that of the intermediate toothed wheel 23 and the first pedal arm 2 around an axis coinciding with that of the intermediate toothed wheel 23'.
Les fig. 3 et 4 montrent une variante du m6ca- nisme de propulsion. Pour simplifier 1e dessin et aussi pour montrer un autre emploi de la bicyclette ä lon- gues pedales oseillantes, an a supprim6 1e dispositif de synchronisation du mouvement des bras de p6da- les. La remontee de la p6dale ä vide est assuree par Je pied chaussant un chausse-pied 25, la course du bras de pMale gtant limitee par une double but & 26 munie d'amortisseurs de chocs 61astiques 2.6'. Cette disposition permet ä une personne ne disposant que dune Jambe pour pMaler, d'utiliser la bicyclette en actionnant une pMale seulement, la Jambe malade reposant Sur la pMale non utilisee qui reste constam- ment dans la position basse. Figs. 3 and 4 show a variant of the propulsion mechanism. To simplify the drawing and also to show another use of the bicycle with long swaying pedals, the device for synchronizing the movement of the pedal arms has been eliminated. The ascent of the vacuum pedal is ensured by the foot fitted with a shoehorn 25, the travel of the pedal arm being limited by a double goal 26 fitted with 2.6' elastic shock absorbers. This arrangement allows a person with only one leg to wear to use the bicycle by operating only one leg, the diseased leg resting on the unused leg which remains constantly in the low position.
Les fig. 3 et 4 ne montrent que la pMale gauche et son mecanisme de propulsion. Figs. 3 and 4 show only the left pMale and its propulsion mechanism.
Le bras de pMale 28 est plus long que le bras de pedale 2 des fig. 1 et 2 et oscille autour d'un axe 30 solidaire d'un prolongement 31' de la fourche 31. Le secteur 32 qui peut etre d6plac6 1e long et blo- que sur 1e bras 28 engrene avec un pignon interchan- geable 33, solidaire en rotation de la roue dentee 34 engrenant avec la roue dentee 35 montee Sur Faxe 29 de la roue arriere 36, la roue dent@e 35 Etant soli- daire de Faccouplement ä roue libre du moyeu de la roue arriere. Le mouvement oscillant deseendant du bras de pedale 28 et par cons6quent du secteur solidaire 32 fait toumer le pignon 33 et la roue den- t & solidaire en rotation 34 dans 1e sens des aiguilles dune montre tandis que la roue dentee 35 engrenant avec la roue 34 tournera dans 1e sens contraire ä celui des aiguilles dune montre et 1'aecouplement ä roue libre (non dessin6) solidaire de la roue 35 en trainera la roue arriere 36 en rotation. The pMale arm 28 is longer than the pedal arm 2 of FIGS. 1 and 2 and oscillates around an axis 30 integral with an extension 31' of the fork 31. The sector 32 which can be moved along and locked on the first arm 28 meshes with an interchangeable pinion 33, integral in rotation of the sprocket 34 meshing with the sprocket 35 mounted on the axle 29 of the rear wheel 36, the sprocket 35 being integral with the overrunning coupling of the hub of the rear wheel. The oscillating movement coming from the pedal arm 28 and consequently from the integral sector 32 causes the pinion 33 and the cog wheel 34 to rotate in the clockwise direction while the cog wheel 35 meshes with the wheel 34 will rotate counter-clockwise and the overrunning coupling (not shown) integral with wheel 35 will cause rear wheel 36 to rotate.
Lors de la remont & de la pMale, la roue 35 toumant dans 1e sens des aiguilles dune montre n'en- traine pas 1e RTI ID="0002.0552" WI="10" HE="4" LX="1368" LY="1836"> moyeu de la roue arriere, (roue libre). When winding up the pMale, wheel 35 rotating clockwise does not drive the RTI ID="0002.0552" WI="10" HE="4" LX="1368" LY= "1836"> rear wheel hub, (freewheel).
Il est Evident que 1e dispositif de Synchronisation du mouvement de va-et-vient des bras de pddales d6erit avec 1e m6canisme de propulsion des fig. 1 et 2, peut egalement s'adapter au m6canisme de propul- sion selon les fig. 3 et 4. It is obvious that the device for synchronizing the to-and-fro movement of the pedal arms derives from the propulsion mechanism of FIGS. 1 and 2, can also be adapted to the propulsion mechanism according to FIGS. 3 and 4.
