Abstract
Abstract A water exercise device to be worn by a person who is desirous of acquiring increased buoyancy while exercising in water. The device includes a waist-encircling band of flexible buoyant material such as elastomeric foam through which is intertwined a flexible and inextensible belt to be strapped around the user's wait. The buoyant band extends circumferentially behind the wearer from just forward of each hip where it terminates in an enlarged lobe portion. Thus the stomach and general body area in front of the wearer are free from interference and the buoyancy of the two lobe portions and interconnecting back band tend to raise the wearer to a vertical position as opposed to a naturally occurring forward face to the water position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
A water exercise device to be worn by a wearer to increase buoyancy thereof comprising, in combination, an elongate waist-encircling band of flexible buoyant material and an inextensible flexible belt coextensive therewith for strapping about the wearer's waist, said buoyant band having a minimum uniform vertical extent surrounding the waist of the wearer, said buoyant band terminating at each end just forward of the hip on each side of the wearer, said each end having an enlarged lobe portion, said lobe portion comprising an upper part extending above said uniform minimum vertical extent and a lower part extending below said uniform minimum vertical extent, said upper part being located nearer said each end of said elongate band such that, when worn, said upper part is positioned further forward of said lower part.
Claim 2
Dependent Claim
132 words
A water exercise device to be worn by a wearer to increase buoyancy thereof comprising, in combination, an elongate waist-encircling band of flexible buoyant material and an inextensible flexible belt coextensive therewith for strapping about the wearer's waist, said buoyant band having a minimum uniform vertical extent surrounding the waist of the wearer, said buoyant band terminating at each end just forward of the hip on each side of the wearer, said each end having an enlarged lobe portion, said lobe portion comprising an upper part extending above said uniform minimum vertical extent and a lower part extending below said uniform minimum vertical extent, said upper part being located nearer said each end of said elongate band such that, when worn, said upper part is positioned further forward of said lower part.
Claim 3
Dependent Claim
29 words
The water exercise belt of claim 1 wherein said elongate waist band is a strap of closed cell foam selected from the group consisting of polyethylene, polyurethane, or polypropylene.
Claim 4
Dependent Claim
63 words
The water exercise belt of claim 2 wherein said elongate waist band is a strap of generally uniform cross-section and said lobe portions at each end thereof extending substantially above and below the minimum uniform vertical extent of said band to provide an upper part adjacent to the hips of the wearer and a lower part adjacent to the sides of the wearer.
Claim 5
Dependent Claim
142 words
A water exercise device to be worn by a wearer desirous of acquiring a different buoyancy while exercising comprising, in combination, a waist-encircling band of homogeneous elastomeric material which is attached to an inextensible belt secured about the waist of the wearer, said band having a minimum uniform vertical extent, said minimum uniform vertical extent wrapping circumferentially around the wearer's back, said band further having enlarged lobe portions which protrude a substantial distance above and below said minimum uniform vertical extent of said band, said lobe portions comprising an upper part for abutting the hip region of the wearer and a lower part for abutting the side region of the wearer, whereby said upper part is worn further forward than said lower part, whereby the buoyant force exerted upon the wearer is non-uniform due to the geometric irregularities of said lobe portions.
Claim 6
Dependent Claim
142 words
A water exercise device to be worn by a wearer desirous of acquiring a different buoyancy while exercising comprising, in combination, a waist-encircling band of homogeneous elastomeric material which is attached to an inextensible belt secured about the waist of the wearer, said band having a minimum uniform vertical extent, said minimum uniform vertical extent wrapping circumferentially around the wearer's back, said band further having enlarged lobe portions which protrude a substantial distance above and below said minimum uniform vertical extent of said band, said lobe portions comprising an upper part for abutting the hip region of the wearer and a lower part for abutting the side region of the wearer, whereby said upper part is worn further forward than said lower part, whereby the buoyant force exerted upon the wearer is non-uniform due to the geometric irregularities of said lobe portions.
