BESKRIVELSEDESCRIPTION

Benævnelse Kædebaseret løftesystem til handicaplifte med skrå løftebevægelse.Name Chain-based lift system for handicapped lifts with oblique lifting movement.

Frembringelsens anvendelsesområdeScope of production

Denne frembringelse angår et løftesystem til kørestolslifte mm, hvor det ønskes, at liften bevæges langs trappen uden at røre denne, og hvor det tilstræbes, at indbygningsmålene begrænses.This provision relates to a lifting system for wheelchair lifts etc., where it is desired that the lift be moved along the stairs without touching it, and where the aim is to limit the installation dimensions.

Kendt teknikPrior art

Allerede tilgængelige typer af løftsesystemer til kørestolslifte med skrå bevægelse er: - Platform monteret på og styret af én eller flere skinner på væg eller trappevæm. Løftebevægelsen sker ved hjælp af kædetræk, spindel eller wiretræk.Already available types of lifting systems for wheelchair lifts with oblique movement are: - Platform mounted on and controlled by one or more rails on the wall or staircase. The lifting movement is done by means of a chain pull, a spindle or a wire pull.

- Stol med sikkerhedsseler. Stolen er monteret på og styret af én eller flere skinner på væg eller trappevæm. Løftebevægelsen sker ved hjælp af kædetræk, spindel eller wiretræk.- Seat belt. The chair is mounted on and controlled by one or more rails on the wall or staircase. The lifting movement is done by means of a chain pull, a spindle or a wire pull.

Problemer, der skal løsesProblems to be solved

De allerede tilgængelige typer er meget pladskrævende.The types already available are very space consuming.

Da både den/de bærende skinner og løftesystemet er placeret på væg eller væm langs trappen, optager konstruktionen en del plads, også når liften ikke er i brug.As both the support rail (s) and the lifting system are located on a wall or hanger along the stairs, the structure occupies a lot of space, even when the lift is not in use.

Endvidere er den synlige konstruktion ofte svær at indpasse arkitektonisk i ældre bygninger.Furthermore, the visible construction is often difficult to fit architecturally into older buildings.

Den ny teknikThe new technology

Det nye ved frembringelsen udgøres af, at 4 kæder, der varetager løftebevægelsen, er udformet på en sådan måde, at de tillige varetager styringen af liftens bevægelsesretning.What is new in the production is that 4 chains that handle the lifting movement are designed in such a way that they also control the direction of movement of the lift.

Kædens led er udformet, så kæden kun kan bøjes til én side.The chain link is designed so that the chain can only be bent to one side.

Liftens platform er understøttet af en kæde i hvert hjørne.The platform of the lift is supported by a chain in each corner.

Når løftebevægelsen startes, skubbes kæderne ved hjælp af tandhjul på de forreste kæder op, så platformen bevæges parallelt med trappen. Da kæderne ikke kan bøjes "bagover" vil bevægelsen være lineær, eller svagt buet, afhængig af kædens eventuelle udbøjning.When the lifting movement is started, the chains are pushed up by means of gears on the front chains, so that the platform moves parallel to the stairs. Since the chains cannot be bent "backwards", the movement will be linear, or slightly curved, depending on the possible bending of the chain.

En justeringsmulighed i forbindelse med tandhjulenes fastgørelse sikrer, at hældningen kan tilpasses til trappen, og der kan kompenseres for evt slitage. Når platformen sænkes, kan kæden "miles op" på en begrænset plads.An adjustment option in connection with the gears attachment ensures that the slope can be adjusted to the stairs and any wear can be compensated. When the platform is lowered, the chain can "miles up" in a confined space.

Claims

1. Wheelchair lift support system, which is new in that the platform is supported by 4 chains. The chains are designed so that they cannot "bend backwards". The result is that the chains both lift and control the direction of the platform. The principle enables the lifting system and the lifting device to be placed under the platform.
