ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to air mattresses and more particularly pertains to a new articulated air mattress for maneuvering bed-ridden patients.
2. Description of the Prior Art
The use of air mattresses is known in the prior art. More specifically, air mattresses 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. 3,935,604; U.S. Pat. No. 3,875,599; U.S. Pat. No. 5,072,468; U.S. Pat. No. 5,070,599; U.S. Pat. No. 5,103,519; and U.S. Pat. No. 5,560,057.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new articulated air mattress. The inventive device includes a base portion. The base portion has a top wall, a bottom wall, and a peripheral side wall. At least one lifting member comprises a top surface, and a bottom surface. A perimeter wall is integrally coupled to and extends between the top and bottom surfaces. The lifting member is generally wedge-shaped such that the bottom surface and the top surface each have a first edge positioned generally adjacent to each other and a second edge spaced from each other. The first edges define a proximal edge and the second edges defined a distal edge. The lifting member is comprises of a flexible and air impervious material. The lifting member has an opening therein adapted for receiving and expelling air. The opening is adapted to be selectively opened and closed. The proximal edge is hingedly coupled to the top wall. Wherein the lifting member is inflated such that a top surface of the lifting member is in an angular relationship with the base portion.
In these respects, the articulated air mattress 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 maneuvering bed-ridden patients.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of air mattresses now present in the prior art, the present invention provides a new articulated air mattress construction wherein the same can be utilized for maneuvering bed-ridden patients.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new articulated air mattress apparatus and method which has many of the advantages of the air mattresses mentioned heretofore and many novel features that result in a new articulated air mattress which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art air mattresses, either alone or in any combination thereof.
To attain this, the present invention generally comprises a base portion. The base portion has a top wall, a bottom wall, and a peripheral side wall. At least one lifting member comprises a top surface, and a bottom surface. A perimeter wall is integrally coupled to and extends between the top and bottom surfaces. The lifting member is generally wedge-shaped such that the bottom surface and the top surface each have a first edge positioned generally adjacent to each other and a second edge spaced from each other. The first edges define a proximal edge and the second edges defined a distal edge. The lifting member is comprises of a flexible and air impervious material. The lifting member has an opening therein adapted for receiving and expelling air. The opening is adapted to be selectively opened and closed. The proximal edge is hingedly coupled to the top wall. Wherein the lifting member is inflated such that a top surface of the lifting member is in an angular relationship with the base portion.
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 articulated air mattress apparatus and method which has many of the advantages of the air mattresses mentioned heretofore and many novel features that result in a new articulated air mattress which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art air mattresses, either alone or in any combination thereof.
It is another object of the present invention to provide a new articulated air mattress which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new articulated air mattress which is of a durable and reliable construction.
An even further object of the present invention is to provide a new articulated air mattress 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 articulated air mattress economically available to the buying public.
Still yet another object of the present invention is to provide a new articulated air mattress 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 articulated air mattress for maneuvering bed-ridden patients.
Yet another object of the present invention is to provide a new articulated air mattress which includes a base portion. The base portion has a top wall, a bottom wall, and a peripheral side wall. At least one lifting member comprises a top surface, and a bottom surface. A perimeter wall is integrally coupled to and extends between the top and bottom surfaces. The lifting member is generally wedge-shaped such that the bottom surface and the top surface each have a first edge positioned generally adjacent to each other and a second edge spaced from each other. The first edges define a proximal edge and the second edges defined a distal edge. The lifting member is comprises of a flexi
