Chair lift installed on staircase - has chair guides detachable from holders on staircase

摘要

The chair travels up and down a slope along two guides (12,13). The guides are positioned one above the other, and they are joined to each other by holders (2), from which they are detachable. The guides can each have two legs (3,4) extending downwards, and which are fixed to different steps. Each leg can be telescopic and lockable in different positions, to give different lengths. Each guide can be formed by lengths of tube detachable from each other. Each holder can have a locking device fixed in position so as to join it and the guide at the desired angle, automatically determining the distance between the guides in the process.
