A firefighter rescue system includes a pair of clasp members connected to opposing ends of a longitudinally extended and flexible harness. The system further includes a pair of handles respectively secured to the harness in longitudinally spaced relationship. The flexible harness includes first and second strap members. The first strap member is coupled to one of the pair of clasp members on one end thereof, and affixed on an opposing end to a length adjusting mechanism. The second strap member has a first end thereof coupled to the other of the pair of clasp members and an opposing second end threaded through length adjusting mechanism. By that arrangement, a distance between the first end of the second strap member and the length adjusting mechanism is adjustably settable.

The present invention relates to a facility comprising: a fixed frame fixedly installed on an outer wall of a veranda or a balcony of a high-rise building; a foldable evacuation box which can be unfolded in the form of a rectangular parallelepiped having an open top side and has and evacuation door on a side thereof; a fall prevention and evacuation means which can be structurally changed to an emergency stairway for fire evacuation; an evacuation box locking means which allows the foldable evacuation box to be unfolded in a rectangular parallelepiped form; a locking means which holds and fixes the fall prevention and evacuation means to the fixed frame; and an entry prevention door which prevents an evacuee from entering inside a veranda or a balcony from the foldable evacuation box through the fixed frame.

A protective cover for an emergency worker oxygen tank has a rigid protective cover member with a knob protection portion and a tank attachment member. The tank attachment member is fixedly attached to the rigid cover member. The tank attachment member is capable of being securely attached to a portion of a standard oxygen tank or a portion of the frame supporting said oxygen tank used by emergency workers. The oxygen tank is commonly strapped onto the emergency worker's back via a standard rigid frame. The rigid protective cover member includes a knob protection portion that is appointed to extend around and over an adjustment knob portion of the oxygen tank to prevent damage and facilitate transport.

Disclosed is a rescue robot for searching trapped persons for firefighting, including a mobile base. Mobile rollers with self-locking mechanisms are mounted at a bottom of the mobile base, a machine mounting seat is fixed to the mobile base, a rotating column is arranged at the top of the machine mounting seat, a driving motor is mounted at a bottom of an inner cavity of the machine mounting seat, a right output end of the driving motor is sleeved with a driving bevel gear, a bottom of the rotating column penetrates through a top of the machine mounting seat and is sleeved with a driven bevel gear, the driving bevel gear and the driven bevel gear are mutually meshed, a portion of an outer wall of the rotating column is fixedly sleeved with a fixed seat, left and right sides of the fixed seat are symmetrical bridge cranes.

A fire escape chamber includes a hermetically sealable outer cage with outer side wall elements, with an outer floor element and with an outer ceiling element. Fire protection insulation layers are provided on the inner sides of the outer elements with some fastened by pin elements, which protrude from the outer side wall elements and from the outer ceiling element into the respective fire protection insulation layers. An inner cage has inner side wall elements, an inner ceiling element and an inner floor element. The inner floor element is mounted in a supporting manner on the fire protection insulation layer of the outer floor element. The inner side wall elements and the inner ceiling element are formed by a plurality of support structure elements, on the inner sides of which panels are, in turn, fastened. The support structure elements are located at spaced locations from the pin elements.

A runner 7 has a housing 21 with two runner wheels 23 attached to the housing. The housing includes a sleeve 25 that can freely turn around the longitudinal axis 27 in a channel 29 present in the housing. The sleeve constitutes an elongated guide opening by which the runner can be moved over the guide cable. Longitudinal slots extending in axial direction are present in the walls 21A, 25A of the channel 29 and of the sleeve 25. Each slot has a middle section 31A, 33A. The width 34 of the middle section 33A of the longitudinal slot in the sleeve is smaller than the width 32 of the middle section 31A of the longitudinal slot in the housing, and, furthermore, the width 34 of the middle section 33A of the slot 33 in the sleeve is smaller than the diameter of the guide cable 3 the runner 7 is suitable for.
