Abstract

En trapp med omstillbare trinn om-fatter to sidestykker (10, 11), som er. stivt forbundet med hverandre, og mellom. hvilke flere trinn (16-19) er anordnet.Hvert trinn er ved sine ender svingbart. om en aksel (25-28) i det inntil liggende. sidestykket og er forbundet med en for-bindelsesarm (29-32), som igjen er forbundet med et innstillbart forbindelsesorgan (33) . Dette forbindelsesorgan kan. ved hjelp av en manøvreringsarm (20) om-stilles slik at trinnene svinges om sine. aksler under opprettholdelse av parallel-litet mellom trinnenes oversider, slik at. vinkelen mellom trinnenes oversider og. sidestykkenes lengderetning forandres.Trinnene (16-19) er utformet slik at de endog kan svinges til ett felles plan, slik at trinnene danner en praktisk talt kontinuerlig plan flate.Ved omstilling av trinnene kan trinnenes oversider innstilles praktisk talt horisontale uavhengig av sidestykkenes helning i forhold til horisontalplanet, slik at trappen blir bekvem å bruke, eller trinnene kan også bringes til å danne en plan flate, slik at trappen kan anvendes som en rampe, f.eks. for transportvogner. og rullestolerA staircase with adjustable steps comprises two side pieces (10, 11), which are. rigidly connected to each other, and between. which several steps (16-19) are arranged. Each step is pivotable at its ends. about a shaft (25-28) in the adjacent. the side piece and is connected to a connecting arm (29-32), which in turn is connected to an adjustable connecting member (33). This connecting means can. by means of a maneuvering arm (20) is adjusted so that the steps are pivoted about their own. shafts while maintaining parallelism between the upper sides of the steps, so that. the angle between the tops of the steps and. The longitudinal direction of the side pieces changes. The steps (16-19) are designed so that they can even be pivoted to a common plane, so that the steps form a practically continuous flat surface. relative to the horizontal plane, so that the stairs become comfortable to use, or the steps can also be made to form a flat surface, so that the stairs can be used as a ramp, e.g. for transport wagons. and wheelchairs
