Abstract
Abstract A deep water exercise belt, which supports the user in deep water in an upright, running position so as to allow vigorous exercise without placing body weight on the legs, involves a waist encircling belt of flexible buoyant material of uniform thickness which is shaped to provide greater flotation at the back of the user. Shaping includes an increased width of the belt on the back while forming the bottom of the belt to avoid hip motion of the user. The belt may be constructed of a chemically cross-linked polyethylene having an extremely fine closed-cell structure. The interior surface of the belt is smoothed so as to provide a suction effect against the body, while the exterior surface may be roughly textured to provide additional resistance to movement through water. A separate band of elasticized material is intertwined through the buoyant belt so as to buckle at the front of the user and hold the exercise belt in close contact with the waist. Holes may be formed through the exercise belt across the back portion and below the band to permit any entrapped water or air to escape therethrough.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
A deep water exercise belt, for placement about the waist of a user, comprising: a. a single homogeneous member of flexible buoyant material which is formed of uniform thickness and of varying width, the width of the buoyant material being substantially uniform at the sides of the user and expanding both upwards and downwards at the back of the user; b. the upward and downward expansion of the single homogeneous member of flexible buoyant material being mutually asymmetrical, the upward expansion being of greater extent than the downward expansion and including flexible buoyant material within and bounded by a single upwardly extending arc, having a single peak, and the downward expansion including flexible buoyant material within and bounded by two downward extending arcs which are symmetrically positioned about a vertical line extending downward from the peak of the upwardly extending arc; and c. A band for securing said single homogeneous member of flexible buoyant material tightly and securely about the waist of the user.
Claim 2
Dependent Claim
164 words
A deep water exercise belt, for placement about the waist of a user, comprising: a. a single homogeneous member of flexible buoyant material which is formed of uniform thickness and of varying width, the width of the buoyant material being substantially uniform at the sides of the user and expanding both upwards and downwards at the back of the user; b. the upward and downward expansion of the single homogeneous member of flexible buoyant material being mutually asymmetrical, the upward expansion being of greater extent than the downward expansion and including flexible buoyant material within and bounded by a single upwardly extending arc, having a single peak, and the downward expansion including flexible buoyant material within and bounded by two downward extending arcs which are symmetrically positioned about a vertical line extending downward from the peak of the upwardly extending arc; and c. A band for securing said single homogeneous member of flexible buoyant material tightly and securely about the waist of the user.
Claim 3
Dependent Claim
74 words
The deep water exercise belt, as recited in claim 1, wherein said member of buoyant material is formed with a plurality of openings about its length and said band intertwines through said openings about the entire length of said member of buoyant material, so that the band encircles the waist of the user and holds said buoyant material tightly against the waist of the user from the outside at a plurality of separate locations.
Claim 4
Dependent Claim
30 words
The deep water exercise belt, as recited in claim 1, where the single homogeneous member of flexible buoyant material is formed of chemically cross-linked polyethylene having a fine closed-cell structure.
Claim 5
Dependent Claim
67 words
The deep water exercise belt, as recited in claim 1, wherein the single homogeneous member of flexible buoyant material encircling the waist of the user is without additional covering, and, having an inside surface which faces adjacent the user's skin and an opposing outside exterior surface, the inside surface is formed to be smooth so as to provide a suction effect against the skin of the user.
Claim 6
Dependent Claim
61 words
The deep water exercise belt, as recited in claim 1, wherein the single, homogeneous member of flexible buoyant material encircling the waist of the user is without additional covering, and, having an inside surface which face adjacent the user's skin and an opposing outside exterior surface, the outside exterior surface is roughly textured to provide additional resistance to movement through water.
Claim 7
Dependent Claim
41 words
The deep water exercise belt, as recited in claim 1, wherein the uniform thickness of the single homogeneous member of flexible buoyant material is varied between different belts so as to alter the buoyancy for different sizes and builds of user.
Claim 8
Dependent Claim
294 words
A deep water exercise belt, for placement about the waist of a user, comprising: a. a single homogeneous member of flexible buoyant material, without additional covering, which is formed of uniform thickness and of varying width, the width of the buoyant material being substantially uniform at the sides of the user and expanding both upwards and downwards at the back of the user; b. the upward and downward expansion of the single homogeneous member of flexible buoyant material being mutually asymmetrical, the upward expansion being of greater extent than the downward expansion and including flexible buoyant material within and bounded by a single upwardly extending arc, having a single peak, and the downward expansion including flexible buoyant material within and bounded by two downward extending arcs which are symmetrically positioned about a vertical line extending downward from the peak of the upwardly extending arc; c. the single homogeneous member of buoyant material without additional covering, having an inside surface which faces adjacent the user's skin and an opposing outside exterior surface, the inside surface is formed to be smooth so as to provide a suction effect against the skin of the user, and the outside exterior surface is roughly textured to provide additional resistance to movement through water; and d. a band for securing said single, homogeneous member of flexible buoyant material tightly and securely about the waist of the user, said member of buoyant material being formed with a plurality of openings about its length and said band intertwining through said openings about the entire length of said member of buoyant material, so that the band encircles the waist of the user and holds said buoyant material tightly against the waist of the user from the outside at a plurality of separate locations.
Claim 9
