Laminar spread for beds, transformable into a bathtub

Abstract

LAMINAR SPREAD FOR BEDS, TRANSFORMABLE INTO A BATHTUB; being applied as covering means of a bed, stretcher or similar thing, is characterized because it includes: a square sheet, of waterproof and flexible material, defined by two longitudinal borders and two traverse borders, parallel by twos; two longitudinal fold lines that, in respectively parallel disposition to said longitudinal borders, extend the complete length of the sheet to finish in the traverse borders of the same; so that among such longitudinal fold lines and said longitudinal borders longitudinal walls are conformed, foldable around their own fold lines; two traverse fold lines that, in respectively parallel disposition to said traverse borders, extend the complete width of the sheet crossing the longitudinal fold lines and finishing in the longitudinal borders of the same; so that among such traverse fold lines and those mentioned traverse borders, bolster walls are conformed, being foldable around their fold lines; four oblique fold lines that, uniting the respective intersections of the lines of longitudinal fold and traverse with the corner proximal of the sheet, they define corresponding corner folds foldable against one of said walls; a bottom that, defined by the longitudinal and traverse fold lines, has a mouth for the discharge of liquid, with closing means of the same; a means for supplying rigidity of at least one of the lateral walls, constituted by a rigid member supportable to the border of the wall of application; and means of positional support among the corner folds and the proximal lateral wall against which the same is foldable.

Having thus especially described and determined the nature of the present utility model, and how it can be put into practice, it is declared to claim, as of exclusive right and property:  
     
         1 . LAMINAR SPREAD FOR BEDS, TRANSFORMABLE INTO A BATHTUB; being applied as covering means of a bed, stretcher or similar thing, is characterized because it includes: 
 a square sheet, of waterproof and flexible material, defined by two longitudinal borders and two traverse borders, parallel by twos;    two longitudinal fold lines that, in respectively parallel disposition to said longitudinal borders, extend the complete length of the sheet to finish in the traverse borders of the same; so that among such longitudinal fold lines and said longitudinal borders longitudinal walls are conformed, foldable around their own fold lines;    two traverse fold lines that, in respectively parallel disposition to said traverse borders, extend the complete width of the sheet crossing the longitudinal fold lines and finishing in the longitudinal borders of the same; so that among such traverse fold lines and those mentioned traverse borders, bolster walls are conformed, being foldable around their fold lines;    four oblique fold lines that, uniting the respective intersections of the lines of longitudinal fold and traverse with the corner proximal of the sheet, they define corresponding corner folds foldable against one of said walls;    a bottom that, defined by the longitudinal and traverse fold lines, has a mouth for the discharge of liquid, with closing means of the same;    a means for supplying rigidity of at least one of the lateral walls, constituted by a rigid member supportable to the border of the wall of application; and    means of positional support among the corner folds and the proximal lateral wall against which the same is foldable.    
     
     
         2 ) LAMINAR SPREAD FOR BEDS, TRANSFORMABLE INTO A BATHTUB, in accordance with claim  1 ; characterized because the longitudinal and traverse fold lines, starting from their intersection, define respective corner tracts that finish in the borders of the square sheet.  
     
     
         3 ) LAMINAR SPREAD FOR BEDS, TRANSFORMABLE INTO A BATHTUB, in accordance with claim  1 ; characterized because the foldable corner folds are defined by the respective oblique fold lines and by the respective corner tracts of the longitudinal and traverse fold lines.  
     
     
         4 ) LAMINAR SPREAD FOR BEDS, TRANSFORMABLE INTO A BATHTUB, in accordance with claim  1 ; characterized because the corner folds is foldable against the longitudinal lateral walls in which the means of positional support are found.  
     
     
         5 ) LAMINAR SPREAD FOR BEDS, TRANSFORMABLE INTO A BATHTUB, in accordance with claim  1 ; characterized because the corner folds is foldable against the lateral bolster walls in which the means of positional support are found.  
     
     
         6 ) LAMINAR SPREAD FOR BEDS, TRANSFORMABLE INTO A BATHTUB, in accordance with claim  1 ; characterized because it includes rigid members supportable to each one of the lateral walls.
