ABSTRACT:
TECHNICAL FIELD
This invention relates to apparatus that is used to hold components of a high pressure rescue air bag system so that the components may be readily transported to a desired location as a unit carried by an individual.
BACKGROUND OF THE INVENTION
High pressure air bags are well known devices for use in rescue situations, such bags being employed, when inflated by high pressure air, to lift or separate structures. A common application is to lift a structure to facilitate or enable removal of a person involved in an accident. The terms “rescue air bag” and “rescue air bag system” refer to any air bag or air bag system which is utilized to lift or move structures, including but not limited to rescue situations.
A number of components are employed in a high pressure rescue air bag system. In addition to the bag itself, the system typically includes a high pressure bottle for providing pressurized air or possibly other gas, a high pressure regulator with associated regulator gauge, a high pressure air line extending between the valve/connector of the bottle and the high pressure regulator, and a deadman switch which is associated with another high pressure line extending between the high pressure regulator and the air bag to control flow of high pressure air to the air bag.
The apparatus of the present invention is utilized to releasably hold the bottle, regulator and regulator gauge, high pressure air line extending between the regulator and the bottle, and a deadman switch. The bottle, regulator and regulator valve and air line are maintained in positions of use so that setup at a work site is facilitated. The deadman switch is readily positionable for use upon removal from the apparatus.
Prior art devices are known which are utilized to transport high pressure bottles equipped with high pressure regulators and multi-outlet high pressure manifolds with male and female couplings. Examples of these devices are a working air cart made available by Paratech Incorporated of Frankford, Illinois and the Air Source C.A.R.T. (continuous air resource transport) made available by Interspiro U.S., Incorporated of Branford, Conn. It is also a well known practice to carry a high pressure bottle on one's back. The Walkaway bracket made available by Ziamatic Corporation (also known as Zico) of Yardley, Pa. is employed to store an SCBA unit for accessability.
Related devices are disclosed in the following United States patents: U.S. Pat. No. 5,396,885, U.S. Pat. No. 4,168,0078, U.S. Pat. No. 4,788,973, U.S. Pat. No. 3,791,403, and U.S. Pat. No. 4,944,292.
None of the patents or other prior art indicated above teach or suggest the combination of structural elements disclosed and claimed herein.
DISCLOSURE OF INVENTION
This invention relates to apparatus for holding and transporting high pressure rescue air bag system components. As mentioned above, the terms “rescue air bag” and “rescue air bag system” encompass any airlift bag and airlift bag system whether or not actually employed in a rescue operation.
The apparatus includes a framework of rigid, unitary construction including a base member and an elongated stanchion attached to and extending upwardly from the base member.
The apparatus includes deadman switch retainer means for releasably retaining the deadman switch of a high pressure rescue air bag system on the framework at a first location. The apparatus further includes high pressure regulator and regulator gauge retainer means for releasably retaining the high pressure regulator and regulator gauge of a high pressure rescue air bag system on the framework at a second location.
High pressure air bottle retainer means is provided for releasably retaining the high pressure air bottle of a high pressure rescue air bag system on the framework at a third location. The apparatus and the equipment held thereby can readily be carried as a unit by one or more handles associated therewith. The apparatus is compact and may be deployed and used in tight quarters.
Other features, advantages, and objects of the present invention will become apparent with reference to the following description and accompanying drawings.
