System For Saving And Evacuating Persons, Which Is Applied To Buildings

摘要

The invention relates to a system which is used for saving and evacuating persons and which is applied to buildings. The system is characterised in that it comprises cables (10 and 11) which are formed respectively by smaller interconnected cables (12 and 12′) and which are positioned in a spiral configuration with a calculated pitch. The system also includes a spring hook (1) which is coupled to the spiral surface and which comprises: at one end, a zone providing access (2) to the interior and a transverse projection (3); and, at the opposing end, a zone (4) which is narrower in relation to the first end. According to the invention, a lifting piece (20) is coupled to the spring hook (1) and applied to a harness (21) worn by the user (30). One end of the cable assembly (10 and 11) is fixed to a motor reducer (23) by means of a tension member (22), while, optionally, the opposing end of the assembly is fixed to a lifting body (42) that extends from the lower part of a support (40) that is attached transversely to the facade of a building (41). The support (42) is equipped with a zone (44) for fixing the upper end of the cables and, optionally, a vertical projection (43) from which a guide cable (13) extends. Said guide cable (13) is coupled to the spring hook (1) to enable the harness (21) user (30) to move vertically such as to eliminate the rotation effect. The user or person to be evacuated can descend along a fixed cable that does not turn, rotating the user thereof. In addition, the system includes a braking unit which can be fixed to the upper or lower part of the building or incorporated at the time of the incident, said unit comprising automatic mechanisms.
