Crash protection device for exit or escape hatch of house roof or sloping surface

摘要

The protection device has hand rails, which lie in a rest position on the three sides of a previously or simultaneously mounted grid or step grating that are opposite the tilted side of the sloping surface, such that they do not look like rails, but like extensions of the edge of the grating or grid. One, two or three cables are pulled to release catches, which activated springs, or other mechanical, hydraulic or similar devices. The force of the devices erect telescopic pipes to erect the hand rails of the device.
