Description

Foreliggende oppfinnelse angår en rullestol for kombinert bruk utendørs og innendørs, samt som arbeidsstol.. The present invention relates to a wheelchair for combined use outdoors and indoors, as well as as a work chair.

Rullestolbrukere har vanligvis to rullestoler, mange har tre, nemlig en rullestol beregnet for innendørs bruk, dvs for bruk kun på plant underlag, især på gulv. Slike stoler kan ved forsiktig bruk også kjøre på for eksempel asfalt ol. Wheelchair users usually have two wheelchairs, many have three, namely a wheelchair intended for indoor use, i.e. for use only on level ground, especially on the floor. With careful use, such chairs can also drive on, for example, asphalt etc.

Rullestoler som er beregnet for utendørs bruk, er i regelen store og nesten umulig å bruke innendørs. Det finnes videre en type rullestol som i prinsipp er beregnet for utendørs bruk, men som med noen begrensninger, også kan brukes inne. Wheelchairs intended for outdoor use are generally large and almost impossible to use indoors. There is also a type of wheelchair which, in principle, is intended for outdoor use, but which, with some limitations, can also be used indoors.

Elektriske rullestoler er kostbare ved innkjøp og dette medfører store utbetalinger for staten, i tillegg til at det for den enkelte bruker medfører store ulemper å vedlikeholde og lagre to, kanskje tre rullestoler. Electric wheelchairs are expensive to purchase and this entails large payments for the state, in addition to the fact that maintaining and storing two, perhaps three wheelchairs entails great inconvenience for the individual user.

Med rullestolen ifølge foreliggende oppfinnelse unngås de foran nevnte ulemper ved at den ene rullestol dekker alle bruksområder. Rullestolen ifølge oppfinnelsen er likeledes velegnet som barnestol og kombinerer dermed ennå flere varianter, idet det i dag tilbys en egen serie med barnestoler. With the wheelchair according to the present invention, the aforementioned disadvantages are avoided by the fact that one wheelchair covers all areas of use. The wheelchair according to the invention is also suitable as a children's chair and thus combines even more variants, as today a separate series of children's chairs is offered.

De foran nevnte ulemper med kjente rullestoler og fordeler med rullestolen ifølge foreliggende oppfinnelse oppnås med de i kravene anførte trekk. The aforementioned disadvantages of known wheelchairs and advantages of the wheelchair according to the present invention are achieved with the features stated in the claims.

På tegningen viser figur 1 et skjematisk sideriss av en rullestol ifølge oppfinnelsen og figur 2 viser et grunnriss av rullestolens understell. In the drawing, figure 1 shows a schematic side view of a wheelchair according to the invention and figure 2 shows a ground plan of the wheelchair's chassis.

Hvert av rullestolens fremre hjul 1, drivhjulene, er montert med en motor på en dreiearm 3 som i avstand fra hjulopplagringen er forbundet med en aksel 4. Akselen 4 fra hvert hjul er ført i en bøssing 5 som er fast forbundet med understellets ramme. Each of the wheelchair's front wheels 1, the drive wheels, is mounted with a motor on a pivot arm 3 which, at a distance from the wheel bearing, is connected to an axle 4. The axle 4 from each wheel is guided in a bushing 5 which is firmly connected to the chassis frame.

Når dreiearmene 3 vippes opp, vil understellet senkes inntil rullestolens fotstøtte 6 kommer til anlegg mot underlaget. Dersom dreiearmene 3 roteres ytterligere vil hjulene 1 løftes opp slik at hjulene går fri fra underlaget. I denne stilling kan akslingene 4 kjøres ut og inn av bøssingen 5 for å endre hjulenes 1 sporvidde, eksempelvis fra en smal utførelse for innendørs bruk til en bred og stabil utførelse for utendørs bruk. When the swivel arms 3 are tilted up, the undercarriage will be lowered until the wheelchair's footrest 6 comes into contact with the ground. If the pivot arms 3 are rotated further, the wheels 1 will be lifted up so that the wheels are free from the ground. In this position, the axles 4 can be driven out and in by the bushing 5 to change the track width of the wheels 1, for example from a narrow design for indoor use to a wide and stable design for outdoor use.

I denne stilling kan også hjulene renses ved at de føres opp mot på rullestolen monterte børster og roteres med rullestolens vanlige fremdriftsanordning. Rullestolens bakre hjul 2 er fullt dreibare og festet til en triangelplate hvis andre hjørne er dreibart forbundet med et føringsstag 9. Triangelplatens 7 tredje hjørne er montert dreibart til en tverrplate 8 som igjen er forskyvbar i rullestolens lengderetning. I tverrplatens 8 inntrukne stilling vil hjulene 2 befinne seg relativt kort bak de fremre hjul 1 og relativt tett sammen, slik at rullestolen er velegnet for innendørs bruk når også de fremre hjul 1 er ført mot hverandre. In this position, the wheels can also be cleaned by moving them up against the brushes mounted on the wheelchair and rotating them with the wheelchair's normal propulsion device. The wheelchair's rear wheels 2 are fully rotatable and attached to a triangular plate, the second corner of which is rotatably connected to a guide rod 9. The third corner of the triangular plate 7 is rotatably mounted to a transverse plate 8 which is again displaceable in the wheelchair's longitudinal direction. In the retracted position of the transverse plate 8, the wheels 2 will be relatively short behind the front wheels 1 and relatively close together, so that the wheelchair is suitable for indoor use when the front wheels 1 are also moved towards each other.

Ved å forskyve tverrplaten 8 bakover, fortrinnsvis med en teleskopføring, vil føringsstag 9 styre triangelplatene 7 slik at når føringsarmenes fremre ender 10 kommer til anlegg mot hver sin føringsring 11, vil triangelplatene 7 svinges ut når tverrplaten 8 fremdeles beveges bakover, slik at hjulene 2 bringes ut til en maksimal bredde og dermed stabilitet. By displacing the cross plate 8 backwards, preferably with a telescopic guide, the guide rod 9 will control the triangular plates 7 so that when the front ends of the guide arms 10 come into contact with their respective guide rings 11, the triangular plates 7 will swing out when the cross plate 8 is still moved backwards, so that the wheels 2 brought out to a maximum width and thus stability.

Med dreiearmene 3 kan rullestolens sete etter ønske innstilles fra en negativ tilting, dvs med seteflaten hellende fremover, til en ønsket positiv tilting og videre avhengig av dreiearmenes 3 lengde. With the swivel arms 3, the wheelchair's seat can be set as desired from a negative tilt, i.e. with the seat surface sloping forward, to a desired positive tilt and so on depending on the length of the swivel arms 3.

Alle bevegelser utføres elektrisk, dvs rotasjon av dreiearmene 3 om akslingene 4, aksial bevegelse av akslingene 4 og bevegelse av tverrplaten 8 i rullestolens lengderetning. All movements are performed electrically, i.e. rotation of the pivot arms 3 about the shafts 4, axial movement of the shafts 4 and movement of the transverse plate 8 in the longitudinal direction of the wheelchair.

Med mulighet til en 180° sving av rullestolens sete egner rullestolen med understellet ifølge foreliggende oppfinnelse seg også meget godt som arbeidsstol ved tilsvarende innstillinger av hhv drivhjulene 1 og de bakre hjul 2. With the possibility of a 180° turn of the wheelchair's seat, the wheelchair with the chassis according to the present invention is also very well suited as a work chair with corresponding settings of the drive wheels 1 and the rear wheels 2.
