ARRANGEMENT IN THE SILL OF AN ELEVATOR CAR, AND SKIRTING

摘要

The object of the invention is an arrangement in the sill of an elevator car, in which arrangement the sill of the elevator car comprises at least a sill profile (2) disposed on the front edge of the floor (1) of the elevator car, which sill profile comprises a guide groove (4) in the direction of movement of the door (3) of the elevator car, along which guide groove the guide shoe (5) of the door (3) is configured to travel, and in which bottom of the guide groove (4) are apertures (6) for dropping assorted debris and small stones out of the guide groove (4). An air duct (8) forming an air space (8a) is fitted below each aperture (6), the bottom end of which air duct is disposed below the raised air pressure zone produced by movement of the elevator car in such a way that the velocity of the air flowing into the air space (8a) from the bottom end of the air ducts (8) is essentially lower than the velocity of the air flowing at the level of the bottom edge of the sill profile (2).
