GONILNI MEHANIZEM ZA POGANJANJE DVOKOLESA Z ENOTHE DRIVING MECHANISM FOR DRIVING TWO WHEELS WITH ONE

NOGONOGO

Predmet izuma je gonilni mehanizem za poganjanje dvokolesa z eno nogo, ki omogoča enostavno poganjanje dvokolesa osebam, ki ne morejo pregibati ene noge v kolenu. Izum spada v razred B 62M 5/00 mednarodne patentne klasifikacije.The object of the invention is a driving mechanism for propelling a two-wheeled bicycle with one foot, which makes it easy to propel the two-wheeler to persons who cannot bend one leg in the knee. The invention belongs to Class B 62M 5/00 of the International Patent Classification.

Tehnični problem, ki ga predložen izum uspešno rešuje je konstrukcija in izvedba gonilnega mehanizma, oziroma takšnega is pogonskega sistema, ki bo omogočal vožnjo z dvokolesom tudi hendikepiranim osebam, predvsem takšnim, ki ne morejo pregibati ene noge v kolenu.The technical problem that the present invention successfully solves is the construction and implementation of the driving mechanism, or one with a propulsion system, which will allow two-wheeled people to drive even with handicapped persons, especially those who cannot bend one leg in the knee.

Dosedaj znani načini poganjanja dvokolesa z eno nogo, temelje predvsem na odmiku nefunkcionalne noge od prosto vrteče se gonilke s pedalom, ki je nameščena na prednjem zobniku verižnega pogonskega mehanizma. Problem, ki se pojavlja pri takem načinu vožnje je, da kolesar s potiskanjem samo ene gonilke z zdravo nogo v določenem delu obrata doseže mrtvo točko, ki jo lahko premaga samo tako, da porine to gonilko, oz. pedalo na tej gonilki (ponavadi s hrbtnim delom stopala) preko te mrtve točke. Tak način poganjanja dvokolesa je nepraktičen in za marsikaterega tudi nevaren, saj kolesar v takem položaju ni stabilen. Za preprečevanje odmikanja noge od pedala gonilke v mrtvi točki ima lahko pedalo na poganjani strani izvedeno zaponko v katero vtaknemo stopalo in na ta način »potegnemo« pedalo in gonilko preko mrtve točke. Tudi tak način je nepraktičen in nevaren, saj je možnost padca kolesarja, ki ima že tako eno nogo nefunkcionalno, drugo pa ima vtaknjeno v zanko na pedalu, zelo velika.The known methods of propelling two-wheeled two-wheelers so far are based primarily on the deviation of the non-functional foot from the freewheel pedal mounted on the front sprocket of the chain drive mechanism. The problem with this type of driving is that by pushing only one gear with a healthy leg, the rider reaches a dead point in a certain part of the turn, which can only be overcome by pushing that gear, or. pedal on that gear (usually with the back of the foot) over this dead end. This way of driving a bicycle is impractical and dangerous for many, since the rider is not stable in this position. In order to prevent the leg from moving away from the dead pedal pedal, the pedal on the driven side may have a buckle in which the foot is inserted and thus "pull" the pedal and the pedal over the dead point. Also, this method is impractical and dangerous, since the chance of a rider falling, who already has one foot dysfunctional and the other stuck in the pedal loop, is very high.

Gonilni mehanizem za poganjanje dvokolesa z eno nogo po izumu, ki je nameščena na strani nefunkcionalne noge, je izvedena tako, da je v trenutni aktivni smeri potiskanja prosto vrteča in istočasno v trenutno neaktivni smeri potiskanja togo povezana preko mehanizma z osjo verižnika, po katerega obodu teče veriga za pogon.The driving mechanism for propelling a two-wheeled two-wheeler according to the invention, which is mounted on the side of the non-functional leg, is configured to be rigidly rotated in the current active pushing direction and at the same time in the currently inactive pushing direction rigidly coupled via a mechanism to the sprocket axis along which the circumference running the drive chain.

is Izum bomo podrobneje obrazložili na osnovi izvedbenega primera in pripadajoče slike, ki kaže:is The invention will be explained in more detail on the basis of an embodiment and an accompanying figure showing:

slika 1 prikaz izvedbe gonilnega mehanizma po izumu v prerezu1 is a cross-sectional view of an embodiment of the driving mechanism of the invention

Namestitev gonilnega mehanizma za poganjanje dvokolesa z eno nogo po izumu je prikazana na sliki 1.The arrangement of the driving mechanism for propelling one-legged two-wheelers according to the invention is shown in Figure 1.

Na verižniku je pri normalnem dvokolesu nameščen par gonilk tako, da sta obe togo povezani z verižnikom in medsebojno razmaknjeni za kotIn a normal two-wheeler, a pair of gears are mounted on the sprocket so that they are both rigidly connected to the sprocket and spaced by an angle

180° . V takem položaju gonilk lahko kolesar z zdravimi okončinami poganja dvokolo tako, da potiska tisto aktivno gonilko, ki je trenutno v zgornjem položaju. Istočasno s prehajanjem aktivne gonilke v spodnji položaj (zaradi opisane namestitve gonilk) neaktivna gonilka sama prihaja v zgornji - aktivni položaj. Na ta način se pretvarja izmenično potiskajoče gibanje gonilk v vrtenje verižnika, preko katerega teče veriga, ki je povezana z zobnikom ponavadi zadnjega pogonskega kolesa.180 °. In this gear position, the rider with a healthy limb can drive the bicycle by pushing the active gear currently in the up position. At the same time as moving the active gearbox to the lower position (due to the described mounting of the gearboxes), the inactive gearbox itself comes into the upper - active position. In this way, the alternating thrusting movement of the gearboxes is transformed into a rotation of the sprocket through which a chain connected to the sprocket of the usually rear drive wheel flows.

Hendikepirane osebe, ki ne morejo potiskati gonilke z eno nogo pri takem normalnem dvokolesu ne morejo izkoriščati ene gonilke, pač pa jim io je vrtenje gonilke na strani neuporabne noge celo v napoto. Zato je po izvedbenem primeru pričujočega izuma gonilka 1 na strani hendikepirane noge na os 4, ki povezuje obe gonilki 1,1’ pritrjena preko sklopa 3, ki omogoča prosto vrtenje gonilke 1 v aktivni smeri in togo povezavo z osjo 4 v nasprotni smeri. Sklop 3 je lahko izdelan kot zobato kolo z enosmerno is sklopko ali na podoben način konstruiran sklop, ki omogoča v eni smeri togo povezavo gonilke 1 z osjo 4, v drugi smeri pa prosto vrtenje gonilke 1. Na ta način nameščena gonilka 1 ima dve prednosti pred znanimi namestitvami gonilk. Prvič je gonilka 1 na strani hendikepirane noge vedno v spodnjem položaju tako, da lahko hendikepirana noga na njej počiva, toga povezava v neaktivni smeri potiska te gonilke pa omogoča premagovanje »mrtvega kota« aktivne gonilke, saj kolesar za prehod te točke samo malo sune z nogo naprej, kar omogoča prehod aktivne gonilke preko »mrtve točke«. Na ta način lahko kolesar, ki ima negibljivo nogo v kolenu normalno poganja dvokolo z zdravo nogo, ne da bi mu bilo potrebno vtikati zdravo ali neaktivno nogo v zanke na pedalih in je na ta način tudi vožnja s kolesom hendikepirane osebe bolj varna. Gonilka 1, ki je na os 4 pritrjena preko sklopa 3 je po pravilu vedno tista gonilka, ki ni pritrjena direktno na verižnik 2. Pri normalnem dvokolesu je ponavadi to vedno leva gonilka. V primeru hendikepirane desne noge potrebno prestaviti verižnik 2 na levo stran in zato obrniti tudi poganjano kolo, kar pa ne omejuje izvedbe pričujočega izuma.People with disabilities who cannot push the one-legged gear in such a normal two-wheeler cannot use the one-gear, but even rotate the gear on the side of the unusable leg. Therefore, according to an embodiment of the present invention, the crank 1 on the handicapped leg side on the axis 4 which connects the two crank arms 1,1 'is secured through the assembly 3, which allows the crank 1 to rotate freely in the active direction and rigidly connect the axle 4 in the opposite direction. The assembly 3 can be designed as a gear wheel with a one-way clutch or similarly designed assembly, which allows rigid connection of the crank 1 in one direction with the axis 4, and in the other direction the free rotation of the crank 1. prior to known crank mounts. For the first time, the handler 1 on the side of the handicapped foot is always in the lower position so that the handicapped foot can rest on it, and the rigid connection in the inactive direction of pushing this handler allows overcoming the "dead corner" of the active handler, since the cyclist only moves slightly with the foot forward, allowing the active gearbox to pass through the "blind spot". In this way, a cyclist who has a fixed leg in the knee can normally drive a two-wheeler with a healthy leg without having to fit a healthy or inactive foot into the pedal loops, making it easier for the disabled person to ride a bicycle. The gearbox 1 that is attached to the axle 4 via the assembly 3 is, as a rule, always the gearbox not directly attached to the sprocket 2. In a normal two-wheeler, this is usually always the left gearbox. In the case of a handicapped right leg, it is necessary to shift the sprocket 2 to the left and therefore to turn the driven wheel, which does not limit the implementation of the present invention.
