<p>System for vertically displacing, in translation, between a high storage position and a lower position of service, a substantially horizontal platform. The system is of the type comprising at least one vertical support column (1) along which the platform (4) slides by means of a support element (2), a device providing a drive for the platform so that the displacement can occur. The system is characterized in that the support element (2) is a tubular element outwardly mounted on the column, at least one part of said tubular element's inner surface contacting the column's (1) outer surface. The invention can be used as a system for displacing a platform forming a bed.</p> |
