ABSTRACT:
A rescue chute suitable for attachment to a fixed structure or to an aerial ladder is disclosed. The chute has two concentric fabric chutes (2,4) supported by a multi-purpose mounting bracket (6). The chutes (2, 4) are made of a heat-resistant material. The outer chute has guying rings (8) along its length and is closed with snap hook-and-ring closures (14). The inner chute (4) has a zipper (18) running the entire length of the chute. Zipper-stops and zipper-pulls allow the inner chute to be opened at the different points to allow people to exit the chute. A snap hook (20) at the end of each zipper (18) ensures that the zipper remains closed as the chute is used. An elastic panel (24) runs the entire length of the chute. The elastic (104) may be sandwiched to protect it from heat. The rescue chute includes a non-abrasive entry flap (26). The multipurpose bracket (6) is adaptable to support the chute on a building wall or on an aerial ladder. The bracket (6) is made of coated tubular aluminum and includes an adjustable clamp (34-40) for securing the rescue chute to a wall or balcony. To secure the rescue chute to an aerial ladder, clamp arms (48) and a leveling arm (50) are provided. A metal spoked adjusting wheel (52) allows the rescue chute to be leveled. Hook clamps (58) are used to grasp the ladder rungs. The chutes (2) and (4) are secured to the multi-purpose bracket by means of grommets, reinforced nylon webbing, bolts, and aluminum strips.
