Description

AluPro technical floor access covers. They are used to conceal floor access openings above basements and unused rooms. They are not suitable for attics: the actuators and the entire mechanism are located under the hatch, in the room below, while the aesthetic side of the hatch is on top, in the floor of the room above. The hatch design is suitable for floors covered with parquet or terracotta tiles. The frame and hatch are installed in the opening at “level 0” below the actual floor (terracotta tiles/boards); the surface of the hatch should be finished with the same material as the rest of the floor—this makes the access hatch aesthetically pleasing and inconspicuous.

Functional Diagram

The flap has a rotating sleeve hinge and is mounted on two gas springs. The power of the gas springs should be matched to the weight of the hatch finish (wood is lighter than ceramics with cement glue). Suggested spring powers in the table. The flap opens after overcoming the force of the magnetic lock (neodymium and sheet metal). Breaking the magnet triggers the process of automatic lifting of the flap. The flap stops in the open position. Closing the flap involves applying a force that breaks the moment of the gas springs until it closes by re-contacting the magnet with the sheet metal. The opening action is initiated by screwing the screw into the hole in the flap and pulling it upwards (the through hole in the flap skin must be maintained).
