DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved aquatic exercise system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the aquatic exercise system 10 is comprised of a plurality of components. Such components in their broadest context include a housing assembly, an operational assembly, and a belt. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
From a specific standpoint, first provided is a housing assembly 14. The housing assembly includes a plurality of hollow pipes. The hollow pipes are fabricated of polyvinyl chloride. The housing assembly includes a base section 16. The base section is horizontally disposed. The base section is in a rectangular configuration. The housing assembly includes a support section 18. The support section is vertically disposed. The support section is also in a rectangular configuration. The support section has a top pipe. The housing assembly also includes an intermediate section 20. The intermediate section is angularly disposed. The intermediate section couples the base section. The intermediate section further couples the intermediate region of the support section. The housing assembly includes a water inlet port 24. The water inlet is provided adjacent to the intermediate region of the housing assembly. In this manner water is provided below the inlet port as a weight. Further in this manner the housing assembly is stabilized the housing. The housing assembly also includes a water outlet port 26. The water outlet portion has a removable cover 28. In this manner emptying the water from the housing assembly when not in use is facilitated.
An operational assembly 32 is provided. The operational assembly includes four block and tackle subassemblies 34. Each block and tackle sub assembly includes a fixed block 36. Each fixed block has a plurality of upper pulleys 38. The upper pulleys depend from the top rail. The upper pulleys are rotatable around a common upper axis. Each block and tackle sub assembly includes a movable tackle 40. Each movable tackle has a plurality of lower pulleys. The lower pulleys are rotatable around a common lower axis. Each block and tackle subassembly includes a cord 44. The cord has a fixed end. The cord also has a movable end. The cord further has an intermediate section. The fixed end is attached to an associated block. The intermediate section winds back and forth between the lower pulleys and the upper pulleys. In this manner pulling the movable end of any cord will raise its associated tackle.
Provided last is a belt 46. The belt has a clip 48. The clip is attached to the movable end of each cord. The belt is positionable around a waist of a swimmer during use while swimming for exercise. A water bucket 50 is provided. The water bucket is attached to each tackle. The water bucket depends from each tackle. In this manner an increased resistive force is provided to the swimmer during use. A pool 54 is provided. A fixed eyelet 52 is provided. The fixed eyelet is attached to the pool 54 during use with the cord passing through the fixed eyelet for guiding purposes. A movable eyelet 56 is provided. The movable eyelet is attached to the bucket during use with the cord passing through the movable eyelet for guiding purposes.
The housing assembly has two vertical end pipes 58, 60 and a vertical center pipe 62. The vertical center pipe is equally spaced between the two vertical end pipes. Two operational subassemblies/block and tackle subassemblies are located on each side of the vertical center pipe. The pipes on one side of the vertical central pipe are adapted to be removed along with the respective two operational subassemblies/block and tackle subassemblies. In this manner the system is rendered for use by two swimmers rather than for use by more swimmers. The pipes on one side of the vertical central pipe are adapted to be separated. A supplemental vertical central pipe may be added with associated horizontal pipes and supplemental operational subassemblies. In this manner the system is rendered for use by six swimmers rather than for use by fewer swimmers.
An alternate embodiment of the invention is shown in FIG. 5. In this embodiment, five upper pulleys 38 are provided and five lower pulleys are provided. The cord 44 provided is of a length to accommodate a swimmer exercising by swimming 25 meters.
In an alternate embodiment 100 of the present invention, nine upper pulleys 104 are provided and nine lower pulleys are provided. A cord 106 is also provided. The cord is of a length to accommodate a swimmer exercising by swimming 50 meters. Note FIG. 6.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
