Title: Motorised drive device for a system for retracting a bed up to the ceiling
Inventor: RICHARD DEVOY
IPC: A47C17/84
Filed: 1990-10-26
Abstract: In this system, the bed is guided on rollers which carry it up or down vertical posts (1) which are permanently installed. The bed is driven manually with the aid of cable means of suspension with pulleys and balancing counterweights [a balancing counterweight]. The suspension cables (15a, 15b) emerge from each of the two posts over a top pulley vertically above the posts (17a, 17b, respectively), are led towards each other and meet in a single direction, for example vertically, joining together to form a single end (23) as they pass over guide pieces such as blocks or wheels (19a, 19b) located in some suitable manner on the structure of the system. Said end (23) formed after said guide pieces is connected to a drive means for bringing about a translational movement of the bed, e.g. a geared motor (27) having a winch (25) onto which said end is wound.
