1. Field of the Invention
The subject invention relates to adapters for two armed powered rescue tools and the methods of using them.
More specifically, the subject invention relates to adapters of two different constructions for connection to one arm of a powered rescue tool and the methods of using the adapters with the powered rescue tool to open a metal door.
2. Description of Related Art including Information Disclosed under 37 CFR 1.97 and 1.98
Two-armed powered rescue tools are well known in the art. They are sometimes referred to as “The Jaws of Life” and by other names. They have various attachments or adapters that are connectable to one of the arms of the tool. A typical two-armed rescue tool is disclosed in U.S. Pat. No. 3,819,153, herein incorporated by reference. The rescue tools are helpful in prying, cutting and squeezing metal in order to gain access to the interior, for example the interior of a vehicle.
The subject adapter is specifically constructed for use with the powered rescue tools and have been found to be highly efficient for use in prying open a metal door.
In one aspect of the invention, a rescue tool adapter is provided for a powered two armed rescue tool utilized for opening metal doors. The adapter has first and second end portions. The first end portion is of general “U” configuration and has first and second legs. The first and second legs are spaced apart a distance greater than the thickness of a door to be opened. The second end portion is connectable to one of the arms of a rescue tool at one end and is connected to the adapter second end portion at the other end.
In another aspect of the invention, a method of using the adapter is described. In this method of using, the adapter set forth immediately above is selected and installed on one leg of the powered rescue tool. The first end portion of the adapter is then hooked over the door and the second rescue tool arm is placed in contact with the door frame at a location spaced from said door. The powered rescue tool is then actuated.
Referring to
Referring to
By providing the apparatus of this invention with a second leg 26 of longer and varying dimensions, an operator can position the second arm 14 of the powered rescue tool at the most advantageous location for exerting force on the door. This is an important aspect of the adapter in that, as is known, in vehicle accidents, doors and door frames become quite distorted resulting in varying positions at which the door can be most conveniently and efficiently opened.
Referring to
The first and second legs 24,26 are spaced apart a distance greater than the thickness of a door to be opened. The second end portion 20 of the adapter 16 is of a construction to be connectable at one end to one of the arms 12 of the powered rescue tool 10 and connected at the other end to the first end 18 portion of the adapter.
For reasons as describe above with reference to
In the method of opening a door 32 with a powered rescue tool 10 comprises selecting one of the rescue tool adapters 16 as set forth above, assembling and installing the rescue tool adapter 16 on one arm 12 of the powered rescue tool 10. The first end portion for the adapter 16 is hooked over the door 32 and the second arm 14 is positioned in contact with the door frame 34 at a location spaced from the door 32. The powered rescue tool 10 is then actuated.
Other aspects, objects and advantages will become apparent from a study of the drawings, the specification and appended claims.
