Multi-positioning therapeutic and comfort pillow

Abstract

A multi-positioning support cushion or support device, such as a pillow is provided. The device is constructed with dual generally opposed convex surfaces being convex about axes that may intersect and are substantially normal to one another. In other embodiments, different angular relationships between the generally opposed convex surfaces may be selected. The pillow is constructed of a multi-layer design, in which a fill material is selected with properties desired for the relative level of comfort and support sought. The fill material then is optionally surrounded by one or more layers of materials, such as a casing and/or a second fill layer. Optionally there are no additional layers.

What is claimed is:  
     
         1 . A multi-positioning pillow comprising: 
 a first convex surface; and    a second convex surface, the second convex surface being generally opposed to the first convex surface.    
     
     
         2 . The multi-positioning pillow of  claim 1  wherein: 
 the first convex surface is convex about a first axis; and  
 the second convex surface is convex about a second axis intersecting the first axis.  
 
     
     
         3 . The multi-positioning pillow of  claim 2  wherein the first and second axes are substantially perpendicular in relation to one another.  
     
     
         4 . The multi-positioning pillow of  claim 2  wherein the first and second axes are substantially co-planar.  
     
     
         5 . The multi-positioning pillow of  claim 1  wherein: 
 the first convex surface has a first curvature; and  
 the second convex surface has a second curvature, the second curvature being different from the first curvature.  
 
     
     
         6 . The multi-positioning pillow of  claim 1  wherein the first convex surface has approximately the same curvature as the second convex surface.  
     
     
         7 . The multi-positioning pillow of  claim 1  further comprising third and fourth convex surfaces, the third convex surface being generally opposed to the fourth convex surface.  
     
     
         8 . The multi-positioning pillow of  claim 7  wherein: 
 the third convex surface is convex in the same general direction as the first convex surface; and  
 the fourth convex surface is convex in the same general direction as the third convex surface.  
 
     
     
         9 . The multi-positioning pillow of  claim 1  wherein the pillow is constructed of a formed polyurethane based foam, the first and second convex surfaces being surfaces of the polyurethane based foam.  
     
     
         10 . The multi-positioning pillow of  claim 1  wherein the pillow is constructed of a polyurethane based foam enclosed within a casing, the first and second convex surfaces being outer surfaces of the casing.  
     
     
         11 . The multi-positioning pillow of  claim 1  wherein the pillow further comprises: 
 a first fill layer; and  
 a casing generally enclosing the first fill layer, the first and second convex surfaces being surfaces of the casing.  
 
     
     
         12 . The multi-positioning pillow of  claim 1  wherein the pillow further comprises: 
 a first fill layer, the first and second convex surfaces being surfaces of the casing; and  
 a casing generally enclosing the first fill layer.  
 
     
     
         13 . The multi-positioning pillow of  claim 11  wherein the first fill layer includes a polyurethane based foam.  
     
     
         14 . The multi-positioning pillow of  claim 11  wherein the first fill layer includes at least one pelletized or particulate material.  
     
     
         15 . The multi-positioning pillow of  claim 12  wherein the first fill layer includes a polyurethane based foam.  
     
     
         16 . The multi-positioning pillow of  claim 12  wherein the first fill layer includes at least one pelletized or particulate material.  
     
     
         17 . The multi-positioning pillow of  claim 1  wherein the pillow further comprises: 
 a first fill layer;  
 a second fill layer generally enclosing the first fill layer; and  
 a casing generally enclosing the second fill layer, the first and second convex surfaces being surfaces of the casing.  
 
     
     
         18 . The multi-positioning pillow of  claim 1  wherein the pillow further comprises: 
 a first fill layer;  
 a second fill layer generally enclosing the first fill layer; and  
 a casing generally enclosing the second fill layer, the first and second convex surfaces being surfaces of the casing.  
 
     
     
         19 . A cushioning or support device comprising: 
 a first convex surface; and    a second convex surface, the second convex surface being generally opposed to the first convex surface.    
     
     
         20 . A toy comprising the cushioning or support device of  claim 19 .  
     
     
         21 . A cushioning or support means comprising: 
 a means for providing a first convex surface; and    a means for providing a second convex surface wherein the second convex surface means is generally opposed to the first convex surface.
