Apparatus for escaping from building on fire

An apparatus for escaping from a building on fire comprising;

• a body frame provided with a gondola,
• a pin-wheel rotatably pivoted on said body frame;
• said pin-wheel being provided with a plurality of pin-rollers projected in the vicinity of an outer circumferential edge of at least one side thereof at predetermined intervals in a circumferential direction and rotatable around an axis parallel to an axis of rotation of the pin-wheel,
• a rolling drum disposed integrally with said pinwheel;
• said rolling drum being provided with a rope for hanging said pin-wheel therearound,
• an anchor hung down under the conditions that one side thereof is closer to said pin-rollers and that it is swingable around an axis shaft line parallel to the axis of rotation of said pin-wheel above said pin-wheel,
• a weight disposed on a lower end side of said anchor,
• an inside block positioned on a rotation locus of said pin-rollers under the condition that said anchor is swung and stopped,
• an guide block disposed outside in a radial direction of said inside guide block to be positioned on the rotation locus of said pin-rollers under the condition that the swing of said anchor is stopped and goes off the rotation locus when said anchor is swung in the direction going away from the rotation axis of the pin-wheel,
• a projection projected outward from an outside edge of an almost middle portion in the circumferential direction of said anchor, and
• a pair of stoppers disposed on a movement locus of said projection to control a swinging amplitude of said projection.
