Aquatic play equipment

Abstract

An aquatic play equipment formed by a flexible thin film to define a space inside for floating on water is provided. The aquatic play equipment has a floating part into which air is supplied for floating on the water, a guiding part which is provided under the floating part and into which water is supplied; and, a planer partition provided between the floating part and the guiding part to prevent fluid-communication therebetween; a lower surface of the guiding part having a convex shape which protrudes into the water. When a person has dived below the aquatic play equipment, since the lower surface has the convex shape, the person can rise to the water surface easily.

What is claimed is: 
     
         1 . An aquatic play equipment which is formed by a flexible thin film to define a space inside for floating on water, comprising:
 a floating part into which air is supplied for floating on the water;   a guiding part which is provided under the floating part and into which water is supplied; and,   a planer partition provided between the floating part and the guiding part to prevent fluid-communication therebetween;   a lower surface of the guiding part having a convex shape which protrudes into the water.   
     
     
         2 . The aquatic play equipment according to  claim 1 , wherein the convex shape is a circular arc column shape. 
     
     
         3 . The aquatic play equipment according to  claim 1 , wherein the convex shape is a triangular column shape. 
     
     
         4 . The aquatic play equipment according to  claim 1 , wherein the floating part and the guiding part are formed separately; and the guiding part is detachably connected to a lower surface of the floating part. 
     
     
         5 . The aquatic play equipment according to  claim 1 , wherein the lower surface of the floating part has same size as an upper surface of the guiding part. 
     
     
         6 . The aquatic play equipment according to  claim 5 , wherein a plurality of eyelets is provided on a periphery of the floating part and the guiding part, and the eyelet provided on the floating part and the eyelet provided on the guiding part are tied by a rope and brought into tight contact. 
     
     
         7 . The aquatic play equipment according to  claim 1 , wherein an air layer is provided by filling the water in a lower part of the guiding part, and by sealing the air in an upper part of the guiding part. 
     
     
         8 . The aquatic play equipment according to  claim 1 , wherein the guiding part makes a person dived below the aquatic play equipment rise to the water surface along the convex shape of the lower surface owing to the force of buoyancy.
