<p>The invention relates to a modular stair lift, which is mounted on the stairs of a construction, for being used by persons with locomotor or other dysfunctions. According to the invention, the lift consists of a driving and transporting module (), which carries one of the seating modules (), in multiple constructive variants, conceived for various weights or positions of the carried person and which shows, between itself and an optional seating module (), depending on the stairs construction, an auxiliary descending module (), the driving and transporting module () carrying a travelling carriage (), which supports, in its turn, some displacing rollers, supported by a box () and shows a stabilizer () which comprises a body (), wherethrough there passes a rod () mounted with a spring (), which is fastened on a pressure plate (), having a mobile part in mechanical contact with a surface () of an arm () and when between the arm () and a lower pipe () there are formed angles tending to 90°, the arm () presses the rod () which compresses the spring () and the more the angle between the arm () and the pipe () approaches closer to 90°, the higher and higher is the force applied, in opposite sense, upon another arm (), so that the wedging effect is completely eliminated, the carriage () supporting the rollers consisting of a main flat support () whereon there are fastened a body () and the box (), any of the seating modules () being mounted on the carrying module () by means of some connectors placed in front of some orifices machined in a plate () of the stabilizer ().</p> |
