As attorney for the inventor of an innovative patented Escape Chute we are currently seeking
manufacturing companies to license, purchase patent rights or enter into a royalty agreement for this
timely invention.
This unique Escape Chute is hinged to a wall of a stairwell, to allow people a safe and rapid exit from a
high-rise building during an emergency situation, when an elevator is not to be used. The Escape Chute
contains spring counter balance support arms and integral handrails, to control the rate of decent and
safety for the people exiting the high-rise building on a slide bed.
The Escape Chute consists of a pivotally mounted slide assembly in an angular condition to the wall above the stairwell. The slide assembly can go from the stored position against the wall to an extended position over the stairwell, allowing safe exit during an emergency.
Objects of the present invention:
Now for the first time a Escape Chute is available for millions of potential users. The low manufacturing cost of the Escape Chute is of major importance.
