Description

Mihelič Niko, dipl. ing.Sklopljivo koloMihelič Niko, B.Sc. ing. Collapsible wheel

Predmet izumaThe subject of the invention

Predmet izuma je sklopljivo kolo, kije predvideno, da se enostavno in hitro brez orodja in posebnega znanja in spretnosti sklopi v tako obliko in s takimi dimenzijami, daje shranljivo v poljubnih prtljažnikih povprečnih osebnih vozil, je pa tudi prenosljivo, pri čemer ohrani vozne lastnosti nesklopljivega kolesa.The object of the invention is a collapsible wheel, which is designed to be easily and quickly assembled without tools and special knowledge in such a form and with such dimensions, it is stored in any luggage compartments of average passenger cars, but also is portable, while maintaining the driving characteristics of the non-collapsible bikes.

Tehnični problemA technical problem

Tehnični problem, ki ga rešuje izum je, kako zasnovati tako sklopljivo kolo. ki bo imelo v voznem stanju enako geometrijo tistih točk, ki določajo vozne lastnosti kolesa in ergonomijo z oziroma na kolesarja kot običajno kolo, medtem ko bo imelo v stanju, ki je predvideno za transport ali hrambo take gabarite, da ustreza dimenzijam prtljažnika manjših osebnih vozil, pri čemer se bo sklapljal brez uporabe orodja in bo v voznem stanju brez zračnosti med sklopljenimi deli.The technical problem solved by the invention is how to design such a collapsible wheel. which in running order will have the same geometry of those points that determine the running characteristics of the bicycle and ergonomics with or on the rider as a normal bicycle, while in the condition intended for transport or storage, such dimensions shall be such as to fit the dimensions of the trunk of smaller passenger cars. , which will be assembled without the use of tools and be in running order with no clearance between the assembled parts.

Znano stanje tehnikeThe prior art

Znana sklopljiva kolesa imajo praviloma dvodelen okvir, ki se razstavlja, prelomi ali teleskopsko krajša. Za zmanjšanje gabaritov v transportnem stanju se lahko še sname kolesi, ki sta manjše dimenzije. Pomanjkljivost vseh rešitev je, da so spoji obeh delov okvira taki, da pride sčasoma do zračnosti ali pa je spoj šibka konstrukcijska točka, v kateri pride do porušitve. Druga pomanjkljivost tehKnown folding wheels generally have a two-piece frame that folds, breaks or is telescopically shorter. Wheels that are smaller in size can still be removed to reduce dimensions in the transport condition. The disadvantage of all the solutions is that the joints of the two parts of the frame are such that over time there is a gap or the joint is a weak structural point at which failure occurs. Another disadvantage of these

28943.doc/XII-02/D31-Vr sklopljivih koles je v tem, da so okvari praviloma krajši in zato ergonomsko neskladni z velikostjo kolesarja. Posledica je, da se s takimi kolesi ni moč udobno voziti na daljše razdalje, izkoristek kolesarjeve energije je manjši, prav tako so vozne lastnosti slabše zaradi spremenjenega predteka prvega kolesa glede na predtek pri kolesih s togim okvirom in večjima kolesoma.28943.doc / XII-02 / D31-Vr of folding wheels is that failures are generally shorter and therefore ergonomically inconsistent with the size of the rider. As a result, such wheels cannot be driven comfortably over longer distances, the cycler's energy efficiency is reduced, and the driving performance is worse because of the altered forebrain of the first wheel relative to that of rigid frame and larger wheels.

Rešitev tehničnega problemaThe solution to a technical problem

Opisani tehnični problem je rešen s kolesom po izumu, katerega bistvena značilnost in novost je v tem, da ostane okvir enak po obliki in dimenzijah okviru običajnega nesklopljivega opziroma togega kolesa, tako moškega kot ženskega, pri čemer pa so nove prve vilice, ki ob enakem predteku, kot pri običajnih kolesih omogočajo za sklaplanje zasuk okoli svoje osi v ležaju krmila za 180θ in nato zasuk kolesa v smeri spodnje prečne cevi okvira, kije dvojna v razmiku tako, da se zasukano kolo ujame v režo med obe cevi, s čimer je fiksirano, obenem pa se tudi krmilo sklopi ob prednjo kolo oziroma ob srednji del okvira. Ker sta kolesi manjši,s premerom okoli 16 palcev·, je s takim zasukom prednjega kolesa pri isti velikosti okvira dolžina sklopljenega kolesa taka, da ga je moč shraniti v običajnem prtljažniku manjšega vozila.The described technical problem is solved with the wheel according to the invention, whose essential feature and novelty is that the frame remains the same in shape and dimensions within the usual non-collapsible rigid wheel, both male and female, with the new first forks being identical such that for conventional wheels, it is possible to swivel about its axis in a 180θ handlebar bearing and then rotate the wheel in the direction of the lower transverse tube of the frame, which double in spacing so that the twisted wheel is trapped in the gap between the two tubes, thereby fixing , and at the same time the handlebars are coupled to the front wheel or the middle of the frame. Because the wheels are smaller, about 16 inches in diameter, with the front wheel swivel at the same frame size, the length of the folded wheel is such that it can be stored in the normal trunk of a smaller vehicle.

Zadnje vilice so zasukljive navzgor pod sedež skupaj z zadnjim kolesom. Zaradi poenostavitve zasuka zadnjih vilic in kolesa je verižni prenos s sprednjega verižnika do zadnjega verižnika izveden z vmesno gredjo in dvema verižnikoma. oziroma dvema zaporednima verigama, s čimer dosežemo še dodatno prenosno razmerje. Hkrati je ta gred tudi vrtišče zasuka zadnjih vilic in zadnjega kolesa. Zato ostaja prva veriga med sprednjim verižnikom in verižnikom na vmesni gredi na istem mestu, medtem ko se druga veriga med sprednjim verižnikom in verižnikom na zadnjem kolesu zasuka z zadnjimi vilicami in zadnjim kolesom, ne da bi se spremenila razdalja med navedenima verižnikoma. Za zmanjšanje bočnega gabarita je predvideno sklapljanje stopalk na gonilkah.The rear forks are swiveled upwards under the seat together with the rear wheel. In order to simplify the rotation of the rear forks and the wheel, the chainring from the front sprocket to the rear sprocket is made with an intermediate shaft and two sprockets. or two successive chains, thus achieving an additional transmission ratio. At the same time, this shaft is also the pivot point of the rear fork and rear wheel. Therefore, the first chain between the front sprocket and the sprocket on the intermediate shaft remains in the same place, while the second sprocket between the sprocket and sprocket on the rear wheel rotates with the rear forks and the rear wheel without changing the distance between the sprockets. To reduce the side gauge, it is intended to fold the pedals on the gears.

Tako kolo je možno prirediti tudi kot tandem, ne da bi ga podaljšali. Prav tako je zaradi normalne velikosti okvira in manjših koles možno pred zadnje kolo v okviru vgraditi pomožen motor, električni ali z notranjim izgorevanje, ne da bi povečali gabarite. Ker je vozna geometrija kolesa po izumu popolnoma enaka vozni geometriji običajnega kolesa, sc vozne lastnosti ne spremenijo in je zato tako kolo primerno tudi za daljše vožnje. Prestave, prednostno notranje, povečujejo vozne lastnosti. Prestavna enota je lahko vgrajena v osi zadnjega kolesa, na vmesni gredi ali pa v gredi gonilk.Such a bicycle can also be tandem without being extended. Also, due to the normal size of the frame and smaller wheels, it is possible to install an auxiliary motor, electric or internal combustion, before the rear wheel, without increasing the dimensions. As the driving geometry of the wheel according to the invention is exactly the same as the driving geometry of a conventional wheel, the sc characteristics do not change, and thus the bike is suitable for longer journeys. Gears, preferably internally, increase driving performance. The gear unit may be mounted in the rear wheel axle, on the intermediate shaft or in the gearbox shaft.

Teža takega kolesa ostane enaka ali manjša glede na težo običajnih koles, zato je v sklopljenem stanju primemo za nošnjo, tudi v posebni torbi ali na nahrbtniku, kije v posebni izvedbi lahko tudi ukrojen posebej za kolo.The weight of such a bicycle remains the same or less in relation to the weight of conventional bicycles, so it is foldable when carried, even in a special bag or backpack, which can also be tailored specifically to the bicycle in a special design.

Prednje vilice omogočajo vgradnjo amortizerjev, ki izboljšujejo vozne lastnosti tako glede stabilnosti kolesa, kot udi glede udobja.The front forks allow for shock absorbers that improve ride performance in terms of wheel stability and limbs for comfort.

Zunanje prestave ob zadnjem kolesu je prav tako možno uporabiti, vendar so manj primerne zaradi majhnega premera koles in sorazmerno visokega napenjalnika verige, ki bi bil s svojim spodnjim delom neugodno malo odmaknjen od podlage.In the ears 27 is mounted a rear wheel 18 which is connected via a second chain 31 through its sprocket 32 to a sprocket 24, further via a sprocket 23 of a chain 25, a front sprocket 15 with gears 16. The rear wheel 18 may have an internal gear assembly which are not shown in the figures. Internal gears may also be provided in the bearing housing 21 of the intermediate shaft 22 or in the gearbox housing 16. Exterior gears at the rear wheel can also be used, but are less suitable because of the small diameter of the wheels and the relatively high chain tensioner, which would be with its lower partly annoyingly slightly off the base.

Zadnje vilice 17 skupaj z zadnjim kolesom 18 in zadnjo verigo 31 se po sprostitvi razstavljive povezave 30, prednostno vijaka, zasukajo okoli vmesne gredi 22The rear forks 17 together with the rear wheel 18 and the rear chain 31 are rotated around the intermediate shaft 22 after releasing the detachable connection 30, preferably screws 22.

28943.doc/Xll-02/D31-Vr naprej proti okviru 1, ne da bi se spremenila razdalja med verižnima paroma, na' katerih sta nameščeni verigi. Zato ni bojazni, da bi se verigi sneli med sklapljanjem in razklapljanjem kolesa. Ta zasnova tudi omogoča popolno zaprtje obeh verig v zaščitna okrova, ki ne ovirata sukanja zadnjega kolesa z zadnjimi vilicami. Zaščitna okrova verig nista prikazana na slikah.28943.doc / Xll-02 / D31-Back to frame 1 without changing the distance between the chain pairs on which the chains are mounted. Therefore, there is no fear that the chain will come off while folding and unblocking the wheel. This design also allows the two chains to be completely enclosed in protective housings that do not obstruct the rear wheel from twisting with the rear forks. The chain guards are not shown in the pictures.

V drugem izvedbenem primeru so zadnje vilice 17 izvedene tako, da sta spodnja kraka 26 zasukljiva okoli osi 19 in tudi opremljena s sredstvom 32 za fiksiranje v voznem stanju kolesa, pri čemer je to sredstvo prednostno izvedeno kot zaskočni element, po potrebi opremljen tudi z blažilnikom in/ali vzmetjo, kar ni prikazano na slikah. Pri tej izvedbi zadnjih vilic odpadeta zgornja kraka.In another embodiment, the rear forks 17 are arranged such that the lower arms 26 are rotatable about the axle 19 and also provided with a means 32 for fixing in the running state of the wheel, the means preferably being engaged as a snap element, and, if necessary, provided with a shock absorber and / or spring, which is not shown in the figures. In this embodiment, the rear forks fall off the upper arms.

Za zmanjšanje širine kolesa sta predvideni znani skl opij i vi stopalki 33 gonilk 16.To reduce the width of the wheel, a known set of pedals 33 of the gears 16 are provided.

Krmilo 34 je večdelno in sicer je srednji del, kije uležajen v krmilnem drogu 35, zasukljiv nazaj in navzdol, hkrati pa sta oba kraka 36 še zasukljiva k okviru 1, da tečeta ročaja 37 tik ob okviru 1.The handlebar 34 is multifaceted, with the middle portion, which is mounted in the steering column 35, pivoting backwards and downwards, while the two arms 36 are further rotatable to frame 1 to flow the handles 37 at frame 1.

Vmesna gred 22 nadalje omogoča predelavo kolesa v tandem, kolo za dve osebi, ne da bi podaljšali okvir 1 s tem, da obe osebi sedita tik ena za drugo. S poljubno izvedeno oporo drugega sedeža 38 druga oseba sedi tik za prvo, na vmesni gredi 22 pa sta lahko izvedeni dodatni gonilki 39, pri čemer sta prednji in zadnji par gonilk usmeijena enako ali v zamiku za 90°, s čimer se pedaliranje obeh oseb ne moti oziroma ovira. Neposreden verižni prenos med verižnikoma 23 in 24 zagotavlja sinhronizirano vrtenje gonilk. Lahko pa vmesna gred 22 ni izvedena z dodatnima gonilkama in je namesto njiju na zadnjih vilicah 17 nameščen par stopalk 40.The intermediate shaft 22 further allows the wheel to be converted into a tandem bicycle for two persons without extending frame 1 by having both persons sit side by side. With the optional support of the second seat 38, the second person sits just behind the first one, and additional gears 39 may be provided on the intermediate shaft 22, with the front and rear pairs of gears smiling in the same direction or 90 ° offset, thus not pedaling the two persons. disturb or obstruct. The direct chain transmission between sprockets 23 and 24 ensures synchronous rotation of the gear units. Alternatively, the intermediate shaft 22 may not be provided with additional cranks and a pair of feet 40 may be mounted on the rear forks 17.

Ker sta kolesi manjši, prednostno 16 palcev, je obremenitev na napere manjša, zato bi isti okvir za eno osebo prenesel tudi obremenitev dveh oseb.Because the wheels are smaller, preferably 16 inches, the load on the spokes is less, so the same frame for one person would withstand the load of two people.

Kolo je nadalje opremljeno z zavorami, svetlobnimi telesi, blatniki, stojalom in drugim, enako kot znana kolesa, ne da bi vse to vplivalo na bistvo izuma.The wheel is further equipped with brakes, luminaires, mudguards, tripods and more, in the same way as known wheels, without affecting the essence of the invention.

Oblika okvira dopušča tudi oblikovne in dimenzijske variacije, v osnovi kot moško, žensko in tudi otroško, pa tudi druge v čisto estetskem smislu, ne da bi spreminjali bistvo izuma, kot je opredeljeno v sledečih patentih zahtevkih.The shape of the frame also allows for design and dimensional variations, essentially as masculine, feminine and also childish, as well as others in a purely aesthetic sense, without changing the essence of the invention as defined in the following patent claims.

Prav tako je možno namesto verižnih prenosov uporabiti jermenska prenosa, prednostno z zobatima jermenoma.Alternatively, it is also possible to use belt transmissions instead of chain transmissions, preferably with timing belts.

Druga oprema, npr. zavore, prestave, svetlobna telesa, stojalo ipd. vplivajo na zasnovo opisanega kolesa po izumu, vendar ne tako, da bi spremenili bistvo izuma, kot je opredeljeno v sledečih patentnih zahtevkih.Other equipment e.g. brakes, gears, light fixtures, stand, etc. affect the design of the described wheel according to the invention, but not by altering the essence of the invention as defined in the following claims.
