Inflatable pool cover assembly

An inflatable pool cover assembly being configured to be selectively inflated to cover a pool, said assembly comprising:

• a top disk being positionable in a pool wherein said top disk is configured to float on water in the pool, said top disk having a top surface and a bottom surface, said top surface having a prominence extending away from said bottom surface to define a housing on said top disk;
• a bottom disk being positionable in the pool wherein said bottom disk is configured to float on water in the pool, said bottom disk having an upper surface;
• a bladder being positioned between said top disk and said bottom disk, said bladder being inflatable to a selected diameter having said bladder engaging an inside surface of a perimeter wall of the pool wherein said bladder is configured to cover the water in the pool, said bladder having a top surface, a bottom surface and an outer surface extending therebetween, said outer surface being continuous such that said bladder has a circular shape, said bottom surface of said top disk being coupled to said top surface of said bladder, said top disk being centrally positioned on said top surface of said bladder, said upper surface of said bottom disk being coupled to said bottom surface of said bladder, said bottom disk being centrally positioned on said bottom surface of said bladder, said outer surface being spaced outwardly beyond a perimeter edge of each of said top disk and said bottom disk when said bladder is inflated such that said outer surface abuts the inside surface of the perimeter wall of the pool wherein said bladder is configured to accommodate pools of varying diameters;
• a plurality of engaging members, each of said engaging members being coupled to said bladder, each of said engaging members releasably engaging the perimeter wall of the pool when said bladder is inflated thereby retaining said bladder in the pool, each of said engaging members being positioned on said outer surface of said bladder, said engaging members being spaced apart from each other and being distributed around an entire circumference of said outer surface, each of said engaging members including a leg extending away from said outer surface and a foot extending downwardly from said leg and being spaced from said outer surface to define a space between said foot of each of said engaging members and said outer surface, said perimeter wall being positioned in said space in each of said engaging members;
• and
• an inflation unit being coupled to said top disk, said inflation unit being in fluid communication with said bladder, said inflation unit comprising:
• a receptacle being positioned within said top disk, said receptacle extending through each of said top surface of said top disk, said bottom surface of said top disk and said top surface of said bladder such that said receptacle is in fluid communication with an interior of said bladder, said receptacle being positioned on said housing, said receptacle being actuatable into an open position to facilitate a gas to pass through said receptacle and into said bladder when said receptacle is turned on, said receptacle being actuatable into a closed position to inhibit the gas to pass through said receptacle when said receptacle is turned off, said receptacle having an input being positioned within said housing;
• and
• a switch being slidably coupled to said top disk, said switch being coupled to said receptacle, said switch turning said receptacle on and off;
• and
• a cartridge being filled with a compressed gas, said cartridge having an output, said cartridge being fluidly coupled to said inflation unit thereby facilitating said compressed gas to exit the cartridge and inflate said bladder, said cartridge being insertable into said receptacle having said output being fluidly coupled to said input.
