ABSTRACT:
A rescue device for use in combination with a hollow basket used to support a workman. The hollow basket includes a floor and an upwardly projecting peripheral sidewall. The upper edge of the sidewall forms an open mouth for the basket to enable a workman to stand within the basket. The rescue device is arranged to raise the workman out of the basket in the event that the workman becomes incapacitated and comprises an inflatable bag having a top and bottom surface, a rigid plate mounted on the top surface and a flexible tube connected to and communicating with the bag. The bag is disposed in the basket so that its bottom surface is on the floor. The plate encompasses the full area of the floor of the basket. The tube extends upward along the sidewall of the basket so that its free end is located adjacent the mouth of the basket for connection to a supply of gas for inflating the bag to cause the plate to move upward toward the mouth of the basket, thereby raising the workman.
