Underwater platforms supported by inflatable sacks

Abstract

A platform structure surrounded by water is disclosed. The platform structure is put together with hollow tubes passing through recesses and internal passages of inflated sacks floating on the water surface, so as to hold a stretched net underwater, thereby providing an underwater platform. The apparatus additionally provides above the water platforms in the form of floating inflatable sacks, which also serve as bumpers having cushioned surfaces in opposite sides of the underwater platform, so that sudden waves do not thrust the underwater platform users against a rigid structure. The apparatus is designed to be disassembled and compactly stored inside the trunk of an automobile.

I claim as my invention:  
     
         1 . An assembly comprising at least two inflatable sacks, supporting at least one underwater platform; 
 wherein the whole assembly floats surrounded by the same body of water;    and wherein said underwater platform is stable enough in calm waters to enable a group of people to stand on their feet and walk around easily, without supporting themselves with their hands, in the whole area within the perimeter of said underwater platform;    and wherein the firm but still cushioned surfaces of said inflated sacks serve as bumpers for the users of said underwater platform, allowing them to relax as they stand on their feet and walk around with their upper bodies over the surface of the water, without fear of being hurt in case a sudden wave thrusts them towards either one of said inflatable sacks;    and wherein to enhance the stability in the water of the entire assembly as said underwater platform is used, and to protect as much as possible the users of said underwater platform from nearby watercrafts, the underwater platform is located at least partially in the middle of said inflatable sacks.    
     
     
         2 . An assembly comprising at least one underwater platform supported by a buoyant structure; 
 wherein the whole assembly floats surrounded by the same body of water;    and wherein said underwater platform is stable enough in calm waters to enable a group of people to stand on their feet and walk around easily, without supporting themselves with their hands, in the whole area within the perimeter of said underwater platform;    and wherein said buoyant structure has firm but still cushioned surfaces which serve as bumpers for the users of said underwater platform, allowing them to relax as they stand on their feet and walk around with their upper bodies over the surface of the water, without fear of being hurt in case a sudden wave thrusts them towards said buoyant structure;    and wherein to enhance the stability in the water of the entire assembly as said underwater platform is used, and to protect as much as possible the users of said underwater platform from nearby watercrafts, the underwater platform is located at least partially in the middle of said buoyant structure.    
     
     
         3 . An assembly comprising a buoyant structure supporting at least one underwater platform; 
 wherein the whole assembly floats surrounded by the same body of water;    and wherein said underwater platform is stable enough in calm waters to enable a group of people to stand on their feet and walk around easily, without supporting themselves with their hands, in the whole area within the perimeter of said underwater platform;    and wherein said buoyant structure has firm but still cushioned surfaces which serve as bumpers for the users of said underwater platform, allowing them to relax as they stand on their feet and walk around with their upper bodies over the surface of the water, without fear of being hurt in case a sudden wave thrusts them towards said buoyant structure.
