Aquatic exercising device

A variable resistance underwater exercising device comprising a support structure, a pair of support arms carried by said support structure, a pair of disc assemblies carried by said support arms and means for adjusting the orientation of said disc assemblies with respect to said support structure, each of said disc assemblies including a rotatably mounted disc, a handle member secured to said disc, a plurality of blades carried by said disc for rotation therewith, a shroud disposed about at least a portion of said blades, means for allowing fluid flow through said shroud, and means for collectively varying the angular orientation of said blades with respect to said disc to vary the resistance of the water on the blades upon the blades being rotated under water by said handle member.

A variable resistance underwater exercising device comprising a support structure, a pair of support arms carried by said support structure, a pair of disc assemblies carried by said support arms and means for adjusting the orientation of said disc assemblies with respect to said support structure, each of said disc assemblies including a rotatably mounted disc, a handle member secured to said disc, a plurality of blades carried by said disc for rotation therewith and means for varying the angular orientation of said blades with respect to said disc to vary the resistance of the water on the blades upon the blades being rotated under water by said handle member, said means comprising a primary gear member, a plurality of secondary gear members, each of said secondary gear members being carried by one of said blades and engaging said primary gear member and means for rotating said primary gear member with respect to said disc for rotating said secondary gear members and varying the angular orientation of said blades with respect to said disc.

A variable resistance underwater exercising device comprising a support structure, a pair of support arms adjustably mounted on said support structure, and a pair of disc assemblies adjustably mounted on said support arms, each of said disc assemblies comprising disc rotatably mounted thereon, a handle member secured to said disc for manual rotation of said disc, a plurality of blades carried by said disc and rotatable therewith, an annular wall disposed about said blades, said wall defining a plurality of apertures therein, a bottom plate member defining a plurality of apertures therein and means for collectively varying the angular orientation of said blades with respect to said disc.

A variable resistance underwater exercising device comprising a support structure defining a base member and a vertical support member, a horizontal support bar, a pair of support arms carried by said support bar, a bracket slidably mounted on said support member, releasable means for securing said bracket to said support member at a desired height thereon, a pair of disc assemblies, and means for pivotally mounting said disc assemblies on said support means, each of said disc assemblies comprising a rotatably mounted disc, a handle member secured to said disc, a plurality of blades carried by said discs for rotation therewith and means for varying the angular orientation of said blades with respect to said discs to vary the resistance of the water on the blades upon the blades being rotated under water by said handles.

A variable resistance underwater exercising device comprising a support structure and a pair of disc assemblies carried by said support structure, each of said disc assemblies comprising a disc rotatably mounted on said assembly, a handle member secured to said disc for manual rotation of said disc, a plurality of blades carried by said discs and rotatable therewith, an annular wall disposed about said blades, said wall defining a plurality of apertures therein, a bottom plate defining a plurality of apertures therein and means for collectively varying the annular orientation of said blades with respect to said discs and means for adjustably mounting said disc assemblies on said support structure such that the axes of rotation of said disc assemblies can bed selectively varied.
