Utførelsesform I ( fig. 1 og 2).Embodiment I (fig. 1 and 2).

Det nedre trinnet ved en sidedør til et kollektiv-kjøretøy, f.eks. en buss, er erstattet av et ytre parti av en plattform 1 som fortsetter innover under bussens chassi. Platte formen 1 bæresaav fire bærere- og løftearmer 536 som er svingbart lagret på hver sin, fra plattformens 1 begge sider ut-stående akseltapper 7>8. Armene 5,6 er alle like lange. To av akseltappene 7 er koaksiale og anbragt nær plattformens 1 The lower step at a side door of a public transport vehicle, e.g. a bus, is replaced by an outer part of a platform 1 which continues inwards under the chassis of the bus. The flat form 1 is supported by four carrier and lifting arms 536 which are pivotally supported on axle pins 7>8 protruding from both sides of the platform 1. The arms 5,6 are all the same length. Two of the axle pins 7 are coaxial and placed close to the platform's 1

ytre ende 3- De to andre 8 er også koaksiale og anbragt såouter end 3- The other two 8 are also coaxial and arranged so

langt fra plattformens 1 indre ende at armene 6, når den indre ende befinner seg i jevn høyde med bussgulvet 2 og ligger an far from the inner end of the platform 1 that the arms 6, when the inner end is at the same height as the bus floor 2 and rests

mot dette, og armene 6 er rettet loddrett nedover, går fri fra bussens øverste trappetrinn 4. Armenes 5,6 andre ender er stivt festet på akseltapper 9,10 som er roterbart lagretii"to bæreskinner 11 og anbragt like langt fra hverandre som akseltappene 7,8. Akseltappene 9,10 bærer hvert sitt kjedehjul against this, and the arms 6 are directed vertically downwards, go free from the top step of the bus 4. The other ends of the arms 5, 6 are rigidly attached to axle studs 9, 10 which are rotatably supported on two carrier rails 11 and placed as far apart as the axle studs 7 , 8. The axle pins 9, 10 each carry their own sprockets

15,16, alle like store. Kjeder 14 er anbragt over kjedehjulene, 15,16, all the same size. Chains 14 are placed over the sprockets,

en på hver side av plattformen li To ikke viste servomotorer er anordnet for å manøvrere kjedene 14 direkte eller in- one on each side of the platform li Two servo motors not shown are arranged to maneuver the chains 14 directly or in-

direkte, slik at bærearmene 5,6 kan svinges synkront og innbyrdes parallelt omkring akseltappene 9,10, og på'den måte forflytte plattformen 1 oppover og nedover under opprettholdelse av dens horisontale stilling. directly, so that the support arms 5,6 can be swung synchronously and parallel to each other around the axle pins 9,10, and in that way move the platform 1 up and down while maintaining its horizontal position.

Bæreskinnene 11 er forsynt med på sine fra plattfdrmenThe support rails 11 are provided with theirs from the plattfdrmen

1 vendende sider anbragte roterbare bærehjul 12,13, innrettet til å rulle mellom i"flensene på to U-bjelker 20, som er anbragt på hver sin side av'plattformen 1 og utenfor bæreskinnen 11. 1 facing sides are arranged rotatable carrier wheels 12,13, designed to roll between the flanges of two U-beams 20, which are placed on each side of the platform 1 and outside the carrier rail 11.

Av bærehjulene 12,13 som er parvis koaksiale, er et par 12 anbragt inntil bæreskinnenes 11 indre ender og et par 13 nær og innenfor bæreskinnenes 11 midtdel. U-bjeikene 20 er i sine to ender forsynt med i og for seg kjente, ikke viste stbppeorganer. Bæreskinnene 11 er anordnet for ved hjelp av ikke viste servomotorer og kunne forskyves mellom to eridestillinger når løftearmene 5,6 er rettet utover langs plattformen 1 sider. Of the carrier wheels 12,13, which are coaxial in pairs, a pair 12 is placed next to the inner ends of the carrier rails 11 and a pair 13 near and within the middle part of the carrier rails 11. The U-beams 20 are provided at their two ends with per se known, not shown, support members. The support rails 11 are arranged by means of servomotors, not shown, and could be moved between two eride positions when the lifting arms 5,6 are directed outwards along the sides of the platform 1.

Av disse endestillingene er den ene plassert slik at plattr formen 1'i denne stilling er inntrukket;.under bussens øverste trappetrinn 4 med sin ytre ende 3 jevnt med bussdøren. Plattformens 1 ytre del tjenestegjør da som bussens nedre trappetrinn. I den andre;-:stillingen, som vist i fig. 1, befinner plattformen 1 seg helt utenfor bussdøren og kan svinges ned til anlegg mot bakken og derfra opp til jevnhøyde med bussgulvet 2, idet den indre ende ligger an mot dette. Under denne svingebevegelse går plattformens 1 bakre ende fri fra det eller de øvre trappetrinn . 4. Of these end positions, one is positioned so that the flat form 1' in this position is retracted under the top step of the bus 4 with its outer end 3 flush with the bus door. The outer part of the platform 1 then serves as the bus's lower step. In the second position, as shown in fig. 1, the platform 1 is completely outside the bus door and can be swung down to rest against the ground and from there up to the same height as the bus floor 2, with the inner end resting against this. During this swing movement, the rear end of the platform 1 is released from the upper step or steps. 4.

Alle i heisen inngående elementer er dimensjonert for med betryggende sikkerhet å kunne bære an rullestol av tyngst type med pasient*-.•. Ved at løftearmenes 5,6 bevegelser er tvangs-koordinært ved hjelp av kjedehjulene 15,16 og kjedenc-14, har man sikret seg mot at plattformen 1 i den høydestilling da løftearmene 5,6 er rettet rett utover, tipper med løftearmene 5 svingenfe nedover og armene 6 svingende oppover. All elements included in the lift are dimensioned to be able to safely carry the heaviest type of wheelchair with a patient*-.•. By the fact that the movements of the lifting arms 5,6 are forced-coordinated with the help of the sprockets 15,16 and the chain 14, it has been ensured that the platform 1 in the height position when the lifting arms 5,6 are directed straight out, tips with the lifting arms 5 swingenfe downwards and the arms 6 swinging upwards.

Utførelsesform II ( fig. 3).Embodiment II ( fig. 3).

Denne utførelsesform skiller seg fra den ovenfor beskrevende ved at kjedehjulene 15,16 og kjeden lM er sløyfet. Sikringen mot plattformens 1 tipping oppnås i stedet ved at løftearmene 5,6 er forsynt med vinkelstilte sidearmer 17,18, This embodiment differs from the one described above in that the sprockets 15,16 and the chain 1M are looped. The protection against tipping of the platform 1 is achieved instead by the lifting arms 5,6 being provided with angled side arms 17,18,

alle like lange og i samme vinkel mot løftearmene 5,6, hvilke all of the same length and at the same angle to the lifting arms 5,6, which

sidearmers 17,18 frie ender er leddbart forbundet med hverandre ved hjelp av leddstenger 19. Svingeservomotorene er anordnet for direkte eller indirekte å påvirke disse sidearmene 17,18. the free ends of the side arms 17,18 are articulately connected to each other by means of connecting rods 19. The swing servomotors are arranged to directly or indirectly influence these side arms 17,18.

Selv om det ovenfor bare er beskrevet og vist to utførelsesformer, akn det allikelvel forekomme andre ut-f ørelsesf ormer innen oppfinnelsens ramme.. Although only two embodiments have been described and shown above, there may still be other embodiments within the scope of the invention.
