ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a storable and deployable fire escape and more particularly pertains to a new fire escape system for providing a means for escape from building structures.
2. Description of the Prior Art
The use of storable and deployable fire escape is known in the prior art. More specifically, storable and deployable fire escape heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. No. 3,692,145; U.S. Pat. No. 4,434,871; U.S. Pat. No. 2,529,112; U.S. Pat. No. 4,815,561; U.S. Pat. No. 3,946,833; and U.S. Pat. No. Des. 370,736.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new fire escape system. The inventive device includes a container having an open front, a back wall, and a door hingedly attached to the container and closeable over the open front, and further includes a motor, a switch member connected to the motor, a battery connected to the switch member, a rotatable first shaft journaled inside the container and driven by the motor, a pair of elongate flexible members carried by the rotatable first shaft, a plurality of rungs having a plurality of stand-off members at the ends thereof and being securely attached to the elongate flexible members with the stand-off members being moveably received in tracks. As a second embodiment, a winch which includes a motor carries a flexible line which is carried about two four-way bearing members and is connected to a lift member which is operated by remote control. As a third embodiment, a spool member carries a flexible line which is carried about two pulleys and is connected to a pair of elongate flexible members which support a plurality of rungs with the bottom rung being weighted.
In these respects, the fire escape system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of providing a means for escape from building structures.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of storable and deployable fire escape now present in the prior art, the present invention provides a new fire escape system construction wherein the same can be utilized for providing a means for escape from building structures.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new fire escape system which has many of the advantages of the storable and deployable fire escape mentioned heretofore and many novel features that result in a new fire escape system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art storable and deployable fire escape, either alone or in any combination thereof.
To attain this, the present invention generally comprises includes a container having an open front, a back wall, and a door hingedly attached to the container and closeable over the open front, and further includes a motor, a switch member connected to the motor, a battery connected to the switch member, a rotatable first shaft journaled inside the container and driven by the motor, a pair of elongate flexible members carried by the rotatable first shaft, a plurality of rungs having a plurality of stand-off members at the ends thereof and being securely attached to the elongate flexible members with the stand-off members being moveably received in tracks. As a second embodiment, a winch which includes a motor carries a flexible line which is carried about two four-way bearing members and is connected to a lift member which is operated by remote control. As a third embodiment, a spool member carries a flexible line which is carried about two pulleys and is connected to a pair of elongate flexible members which support a plurality of rungs with the bottom rung being weighted.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new fire escape system which has many of the advantages of the storable and deployable fire escape mentioned heretofore and many novel features that result in a new fire escape system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art storable and deployable fire escape, either alone or in any combination thereof.
It is another object of the present invention to provide a new fire escape system which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new fire escape system which is of a durable and reliable construction.
An even further object of the present invention is to provide a new fire escape system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such fire escape system economically available to the buying public.
Still yet another object of the present invention is to provide a new fire escape system which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new fire escape system for providing a means for escape from building structures.
Yet another object of the present invention is to provide a new fire escape system which includes includes a container having an open front, a back wall, and a door hingedly attached to the container and closeable over the open front, and further includes a motor, a switch member connected to the motor, a battery connected to the switch member, a rotatable first shaft journaled inside the container and
