ABSTRACT:
The present invention relates generally to fire escapes and more particularly to personal fire escapes of high rise buildings that can be purchased and installed on one's patio or near a bedroom window to be used in the event of an emergency.
Modern high rise buildings often have patios. While modern buildings are always constructed with fire escapes, it is not the case that such buildings commonly have means to escape from the patio of the apartment. In the event of a fire, the traditional means of escape may be blocked or unavailable. Furthermore it is always preferable to have an additional means of escaping a fire. Many such buildings do not have means to escape from the patio.
The present invention addresses these concerns. The following important objects and advantages of the present invention are:
(A) to provide a simple to manufacture and easy to operate fire escape device that is readily attachable to a floor of an above ground patio of an existing high rise building,
(B) to provide a fire escape assembly device that contains three stackable ring elements including a cover, a hollow center ring and a bottom disk that together contain a ladder and circumferentially spaced chain elements attached from the center ring and the bottom disc so that an individual escaping a fire can when the device hangs over an outer railing of a patio climb through the center ring and climb down the ladder to an escape floor,
(C) to provide a fire escape device that includes ring elements, including a cover, that contain and store a ladder and chain elements whereby in stored position the ring elements hang on piping by means of a hinge bracket, which piping is attached to a patio, and whereby the device is activated when the hinge bracket and ring elements are rotated on the piping approximately 270 degrees so that the hinge bracket rests on the outer railing of the patio and the ring elements extend over the outer railing of the patio and the cover is removed thereby allowing the stored ladder and chain elements to fall and provide means of escape,
(D) to provide a fire escape device that includes a ladder whereby the individual using the ladder would be surrounded on all sides by chain elements to which can be added include horizontal connective chains so that if the individual climbing down the ladder loses balance the individual can grab any part of the chain elements to restore balance,
(E) to provide a fire escape device that is made of noncorrosible 16 to 18 gauge aluminum,
(F) to provide a fire escape device that can include a mallet for braking into a window on an escape floor if necessary,
(G) to provide a fire escape device that can include an alarm that electrically and automatically signals a remote station such as a doorman in the building through wires when the fire escape device is separated from a circuitbreaking jack element extending from the railing of the patio as the device is rotated into active position;
(H) to provide a fire escape device that has added stability in active position by means of a small bracket with a central aperture extending from the center ring that can be fastened to an overhead canopy such as with a bar having a hook;
(I) to provide a fire escape device whose transverse piping can be bent so as to allow placement of a convenience step ladder under the piping safe from tampering by children in order to make it easier to climb onto the hinge bracket and into the center ring when the device is placed in active position; and
(J) to provide a fire escape device that can be used on patios or in bedrooms.
U.S. Pat. Nos. 5,842,539 to Hough, 5,311,965 to Wu, 4,705,141 to Splaine, 4,595,075 to Rodrigue, 4,383,592 to Hoffa, 4,164,991 to Marra and 1,753,798 to Martin disclose various kinds of fire escape devices and ladders that can be used in various ways but each suffers from various disadvantages. The wooden storage box of U.S. Pat. No. 5,842,539 used to store and anchor the ladder could itself catch fire and burn. The extensible ladder of U.S. Pat. No. 3,344,886 to Boscarino does not provide a series of chain elements or other structure surrounding the person using the ladder that can be used to hold on to if the person climbing down the ladder loses balance. No known prior art fire escape assembly device discloses a structure as described in the present invention that affords all the advantages of the present invention.
