Underwater viewing facility

Abstract

An underwater viewing facility consisting of a buoyant platform, having a through-hole, the hole employs an underwater observation device in form of a transparent viewing chamber, preferred of a semi-spherical configuration, a chamber in which a person lying prone on the platform, can insert his entire head or at least his face, enjoying a panoramic wide angle sight.

1 . An underwater facility comprising of a buoyant platform, having a through-hole, the hole's diameter is slightly bigger than the size of a human head, the hole employs an underwater observation device, the observation device consists of a transparent viewing chamber, the chamber protruding the bottom of the buoyant platform and means to secure the viewing chamber in the correct position to said hole and in said hole, enabling an observer to lie in a prone position on the buoyant platform with at least his face resting in the transparent viewing chamber. 
     
     
         2 . An underwater facility according to  claim 1 , wherein the buoyant platform is of a rigid material. 
     
     
         3 . An underwater facility according to  claim 1 , wherein the rigid buoyant platform is sloped at its top. 
     
     
         4 . An underwater facility according to  claim 1 , wherein the rigid buoyant platform is foldable. 
     
     
         5 . An underwater facility according to  claim 1 , wherein the buoyant platform is a sea mattress. 
     
     
         6 . An underwater facility according to  claim 1 , wherein the buoyant platform is an inflatable air mattress. 
     
     
         7 . An underwater facility according to  claim 1 , wherein the front of the mattress consists of several rings, of which at least one ring is provided with an inflatable valve of its own. 
     
     
         8 . An underwater facility according to  claim 1 , wherein the buoyant platform's hole is surrounded by a soft protecting ring on the top of the platform, avoiding water to reach the hole, when a viewer's head occupies the hole. 
     
     
         9 . An underwater facility according to  claim 1 , wherein the transparent viewing chamber is slightly bigger than the size of a human head, enabling an observer to put his whole head into the chamber. 
     
     
         10 . An underwater facility according to  claim 1 , wherein the transparent viewing chamber is of a semi-spherical configuration. 
     
     
         11 . An underwater facility according to  claim 1 , wherein the means to secure the viewing chamber in its correct position are an inflatable sleeve provided with its own valve to serve as a lock-belt. 
     
     
         12 . An underwater facility according to  claim 1 , wherein the means to secure the viewing chamber in its position are an integral part of the buoyant platform. 
     
     
         13 . An underwater facility according to  claim 1 , wherein the means to secure the viewing chamber in its position, are part of the observation device. 
     
     
         14 . An underwater facility according to  claim 1 , wherein in addition to other means, the viewing chamber has also a flat ring in a perpendicular position to its upper edge to help to secure the viewing chamber into its position. 
     
     
         15 . An underwater facility according to  claim 1 , wherein the means to secure the viewing chamber in its position, are independent, being neither part of the buoyant platform, nor of the observation device.
