Frembringelsens anvendelsesområdeScope of production

Frembringelsen angår en pedaldrevet trehjulet cykel for transport af gods og personer.The production relates to a pedal-driven tricycle for transport of goods and persons.

Kendt teknikPrior art

Trehjulede transport- og ladcykler har været kendt siden cyklens barndom. Trehjulede transportcykler er typisk opbygget på en af tre måder: 1: med to hjul på linie efter hinanden på hver sin akse og det tredie på seperat akse ved siden af denne linie, hvor det transporterede bæres ved siden af føreren (sidevogn) 2: med to hjul bagtil på fælles akse og et enkelt hjul fortil, hvor det transporterede bæres bag føreren 3: med et enkelt hjul bagtil og to hjul foran på fælles akse, hvor det transporterede bæres foran førerenTricycles transport and charging bicycles have been known since the childhood of the bicycle. Tricycles are typically constructed in one of three ways: 1: with two wheels in a row on each axis and the third on a separate axis next to this line, where the transport is carried next to the driver (sidecar) 2: with two wheels at the rear of the common axis and a single wheel at the front where the transport is carried behind the driver 3: with a single wheel at the rear and two wheels at the front of the common axis where the transport is carried in front of the driver

Denne frembringelse angår en transportcykel opbygget på sidst nævnte måde, hvor føreren hele tiden har overblik over den transporterede last.This provision relates to a transport bicycle constructed in the last-mentioned manner, in which the driver constantly has an overview of the transported cargo.

Fælles for de kendte transportcykler er, at de styrer på det forreste eller de forreste hjul. Foruden stor venderadius medfører det for transportcykler med to hjul og lad foran føreren, enten en transport cykel med højt tyngdepunkt for at muliggøre, at hjulene svinger frit under et fast lad; - eller at det transporterede indgår i styringen, hvor hele ladet med last under styring drejer om en lodret akse under eller umiddelbart bag ladet. Herved øges ved drejning afstanden mellem de i drejningen yderligst liggende hjuls kontaktpunkter med underlaget væsenligt, og da centrifugalkræfterne netop søger at tvinge massen væk fra centrum af drejebevægelsen, mindskes stabiliteten, og føreren er nødsaget til at læne sig kraftigt kontra for at undgå at vælte.Common to the known transport bikes is that they control the front or front wheels. In addition to the large turning radius, this means for two-wheeled transport bicycles and the cargo in front of the driver, either a high-gravity transport bicycle to allow the wheels to swing freely under a fixed charge; - or that the transport is part of the steering, where the entire load with the load under control revolves around a vertical axis below or immediately behind the load. As a result, the distance between the outermost reel's contact points with the support is substantially increased, and as the centrifugal forces precisely seek to force the mass away from the center of the turning motion, stability is reduced and the driver is forced to lean heavily to avoid overturning.

For denne type transportcykler er de kendte udførelser af en sådan art, at steldelen med det drivende hjul og førerens vægt, og steldelen med de styrende hjul og den transporterede vægt er forbundet i det for styringen nødvendige drejende led, hvor en uønskelig del af den pedaltilførte energi afsættes i stellets dele i stedet for i fremdrift.For this type of transport bicycle, the known embodiments are of such a nature that the frame part with the driving wheel and the weight of the driver, and the frame part with the steering wheels and the transport weight are connected in the rotational link necessary for the steering, where an undesirable part of the pedal supplied energy is deposited in the parts of the frame rather than in propulsion.

Ifølge patent DE 33 21 142 Al af den 10. juni 1983 er baghjulsstyring på trehjulede pedaldrevne køretøjer kendt, men både formålet og udførelsen er en ganske anden end denne frembringelse. Formålet er et trædepedal fartøj med hjælpemotor til transport af enkeltpersoner uden gods.According to patent DE 33 21 142 A1 of June 10, 1983, rear-wheel steering on three-wheel pedal-driven vehicles is known, but both the purpose and the embodiment are quite different from this production. The purpose is a pedal pedal vessel with auxiliary motor for transporting individuals without cargo.

Den er udført med to uafhængigt akslede forhjul, der drives hver for sig af henholdvis pedaltræk og hjælpemotor.It is equipped with two independently shafted front wheels that are driven separately by pedal drag and auxiliary motor respectively.

Styringen er udført med et over baghjulet lodret kronrør med een gaffel, der krummer bagud for at opnå efterløb, og et andet foran baghjulet liggende omdrejningspunkt med en skråtstillet styregaffel for at opnå kontrol over hjulet, -altså en udførelse med to gafler, hvor det styrende baghjuls drejeradius begrænses kraftigt af denne topunkts fastholdelse.The steering is made with an overhead rear vertical crown tube with one fork cranked backwards to achieve a trailing edge, and another front of the rear wheel with an oblique steering fork to gain control over the wheel, that is, a two-fork version where the steering rear wheel turning radius is severely limited by this two-point retention.

Det tekniske problem, der skal løsesThe technical problem to be solved

Med frembringelsen ønskes tilvejebragt en trehjulet pedaldrevet transportcykel af typen med ladet foran føreren, hvor der opnås en markant lille venderadius uden at indrage det transporterede i styrebevægelsen og uden nævneværdigt at ændre på afstandene mellem de tre hjul under drejning, så den indbyrdes geometri mellem hjulenes kontaktpunkter med underlaget og dermed cyklens stabilitet opretholdes.With the production, it is desired to provide a three-wheel pedal-driven transport bicycle of the type with the front of the driver, where a markedly small turning radius is obtained without involving it transported in the steering movement and without appreciably changing the distances between the three wheels during rotation so that the mutual geometry between the contact points of the wheels with the support and thus the stability of the bike is maintained.

Der ønskes endvidere tilvejebragt et stift cykelstel, hvor både førerens vægt og den transporterede masse befinder sig på samme steldel med de drivende hjul, så den tilførte energi fra føreren mest muligt afsættes i fremdrift og ikke i stellet. Stel, styre-, bremse- og drivmekanisme ønskes endvidere at være konstruktivt og funktionelt uafhængigt af ladet, så dette kan udskiftes, undværes og udformes efter behov.It is further desired to provide a rigid bicycle frame in which both the driver's weight and the transported mass are on the same frame part with the driving wheels, so that the energy supplied by the driver is deposited as much as possible in the propulsion and not in the frame. Furthermore, the frame, steering, braking and driving mechanism is desirable to be constructive and functionally independent of the load, so that this can be replaced, removed and designed as required.

Der ønskes endvidere tilvejebragt trafiksikre egenskaber, som ud over den nævnte lille venderadius, styringen uden at aktivere den transporterede last og bibeholdelsen af den indbyrdes afstand mellem hjulene under drejning, omfatter lavt tyngdepunkt, hvor ladet søges anbragt så lavt som muligt, kort bremselængde, hvor primærbremsen påvirker forhjulene og endelig stor stabilitet, hvor ladet anbringes imellem et hjulpar.Furthermore, it is desired to provide traffic-safe features which, in addition to the said small turning radius, the steering without activating the transported load and the maintenance of the spacing between the wheels during rotation, include low center of gravity, where the load is sought to be placed as low as possible, short brake length, where the primary brake affects the front wheels and finally great stability where the load is placed between a pair of wheels.

Den nye teknikThe new technique

Det nye ved frembringelsen er, at denne trehjulede transport cykel styrer på baghjulet og trækker på forhjulene via et differentiale, og at den har et udskifteligt lad uafhængigt af selve stellet.What's new about the production is that this tricycle transport bike controls the rear wheel and pulls on the front wheels via a differential and that it has a replaceable bar independent of the frame itself.

Styringen, der foregår med et konventionelt styr, er ny idet den foregår på baghjulet via eet kronrør uden gaffel over styrestænger, som overfører drejemomentet direkte ned i det ene af baghjulets to gaffelben, hvis krone er monteret i et andet kronrør, der er udført i en stump vinkel med vandret i kørselsretningen.The steering with a conventional steering wheel is new in that it is mounted on the rear wheel via one crown tube without a fork over the control rods, which transmit the torque directly into one of the two fork legs of the rear wheel, the crown of which is mounted in another crown tube, which is made in a blunt angle with horizontal in the direction of travel.

Det nye ved fremdriftsmidlet er, at den af føreren i pedalerne afsatte energi overføres til et differentiale, der igen overfører energien til forhjulenes aksel.What is new about the propulsion means is that the energy deposited by the driver in the pedals is transferred to a differential which in turn transfers the energy to the front wheel axle.

Det nye ved stellet, der er opbygget med et lavt tyngdepunkt, er, at det er udført som et konstruktivt stift hele uafhængigt af udformningen af ladet, der er anbragt foran føreren over de trækkende hjul.The new feature of the low center of gravity frame is that it is constructed as a structural pin all independently of the design of the cargo positioned in front of the driver over the towing wheels.

Den tekniske virkningThe technical impact

Styringen er udført således, at cyklen drejer i den retning, man drejer imod med det konventionelle styr, idet den ene styrestang krydser over, så baghjulet reelt drejer modsat.The steering is designed so that the bike rotates in the direction you rotate with the conventional steering wheel, with one steering link crossing over, so that the rear wheel actually turns opposite.

Når styringen foregår på baghjulet opnås en meget lille venderadius især ved lav hastighed, hvor cyklens inderste forhjul i en 180 graders drejebevægelse forbliver stående i centrum af bevægelsen. Dette opnås især på grund af baghjulets montering i eet kronrør, om hvilket baghjulet drejer frit kun begrænset af påsvejste stop i den ønskede drejeradius.When steering takes place on the rear wheel, a very small turning radius is achieved, especially at low speeds, where the inner front wheel of the bicycle in a 180 degree turning motion remains standing in the center of the movement. This is achieved especially because of the rear wheel mounting in one crown tube, about which the rear wheel rotates freely limited only by welded stops in the desired turning radius.

Den indbyrdes geometri mellem de tre hjuls kontaktpunkter med underlaget og dermed cyklens stabilitet ændres kun ganske lidt 2 DK 97 00227 U3 i drejebevægelsen, og den transporterede masse inddrages lKke i styrebevægelsen. Endvidere befinder den samlede masse af fører og det transporterede sig tæt på centrum af drejebevægelsen, hvorved nødvendigheden af at læne sig kontra mindskes væsentligt.The mutual geometry between the three wheel contact points with the support and thus the stability of the bicycle is only slightly changed in the turning movement, and the transported mass is not included in the steering movement. Furthermore, the total mass of the driver is located and it is transported close to the center of the pivotal motion, thereby significantly reducing the need to lean against.

Disse tre egenskaber medfører stærkt mindsket risiko for styrt forårsaget af centrifugalkræfter og mindsket stabilitet eller af, at lasten forskubbes.These three properties result in greatly reduced risk of crash caused by centrifugal forces and reduced stability or by displacement of the load.

Når transportcyklen udføres som anført i krav nr. 2 og 3 opnås, at en linie trukket langs med kronrøret møder det vandrette underlag i et punkt foran baghjulets akses lodrette nedfældning på samme underlag, og at disse linier samtidig krydser hinanden. Herved opnås både efterløb og opretningseffekt, idet kronrørets vinkel forskellig fra lodret bevirker, at baghjulet ikke svinger ukontrollabelt fra side til side som hjulet på en indkøbsvogn.When the transport cycle is carried out as claimed in claims 2 and 3, it is achieved that a line drawn along the crown tube meets the horizontal support at a point in front of the vertical folding of the rear wheel on the same support and that these lines intersect at the same time. This results in both a trailing and rectifying effect, since the angle of the crown tube different from the vertical causes the rear wheel not to swing uncontrollably from side to side like the wheel of a shopping cart.

Når transportcyklen udføres som anført i krav nr. 4 opnås, at uønskede "arme" og beslag ikke skal påsvejses baggaffel eller krone for at overføre drejemomentet fra styrestængerne, men at bevægelsen foregår direkte ned i det ene gaffelben.When the transport cycle is carried out as claimed in claim 4, it is achieved that undesirable "arms" and brackets do not have to be welded to the rear fork or crown to transmit the torque from the guide rods, but that the movement takes place directly down one fork leg.

Når transportcyklen udføres som anført i krav nr. 5 opnås, at cyklen trækker på begge forhjul både ved ligeudkørsel og også under drejébevægelser, hvor forhjulene ikke tilbagelægger lige stor distance. Dette giver et ligeligt slid på begge forhjul.When the transport cycle is carried out as stated in claim 5, it is achieved that the bicycle pulls on both front wheels both at straight ahead and also during turning movements where the front wheels do not cover equal distance. This gives equal wear to both front wheels.

Når transportcyklen udføres som anført i krav nr. 6 opnås, dels at cyklen kan udstyres med et lad udformet efter behov, dels at ladet kan udskiftes til en anden udformning på 10 minutter uden indgriben i selve cyklens grundstel og konstruktion, og dels at den via pedalerne afsatte energi i al væsentlighed omsættes til fremdrift og ikke afsættes i stellet.When the transport cycle is carried out as claimed in claim 6, the bicycle can be equipped with a barge designed as required, and the barge can be changed to another design in 10 minutes without interfering with the basic frame and structure of the bicycle itself and partly by the pedals deposited energy are essentially converted into propulsion and not deposited in the frame.
