Abstract

Retractable platform device intended for multiple uses without obstructing the surface of the premises where it will take place. The device comprises a platform which may take the shape of a movable box remaining in horizontal position during its vertical raising or lowering. At the four corners of the device are secured four cables or straps (129a, 129b), guided by the shieves (127, 17a) and fixed between the side plates (127a) of the driving shaft (123) forming part of a winch on which they are wound and unwound when the user actuates the driving means (101) of said winch thereby causing the lowering of the platform towards bearing points, or its lifting in order to occupy a storage position in a housing provided in the ceiling of a fixed or movable room. The driving means (101) are concentrically mounted inside or outside the winch shaft (123).
