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 pneumatic mattress construction wherein the same can be utilized for providing a lightweight inflatable resting surface.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new pneumatic 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 pneumatic 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.
United States Patent F PNEUMATIC MATTRESS Paul Francois Bose, Villefranche-de-Rouergue (Aveyron), France, assignor to Etablissements Youpa-La, Dijon (Cote-dOr), France, a French company Filed June 1, 1961, Ser. No. 114,194 Claims priority, application France June 7, 1960 Claims. (Cl. 5-448) has for its object a pneumatic mattress which fulfils a double purpose: to improve the comfort of the person lying on it, and in the case of a baby or a sick person subject to enuresis, to avoid the bed remaining wet.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new pneumatic mattress. The inventive device includes a tubular perimeter member having a pair of end portions and a pair of side portions extending between the end portions of the tubular perimeter member. A number of tubular cross members are extended between the side portions of the tubular perimeter member. The lumens of the tubular cross members are in fluid communication with the lumen of the tubular perimeter member.
