Hydrotherapy vest

Claim 2

Apparatus for use by a wearer in performing within a body of water exercise movements corresponding to a land-based running activity, comprising: (a) flotation means substantially conforming to the torso of a wearer for supporting the wearer in water with his body submerged to a level above the shoulders said flotation means extending in front of and behind the wearer's body and being constructed so as to support him in a substantially upright position with a forward lean of less than approximately 30° from the vertical, said position corresponding to a body position assumed in a land-based running activity; and (b) restraining means for holding said flotation means snugly in position on said user during said exercise.

Claim 3

Apparatus as defined in claim 1 wherein said flotation means provides buoyant force proportional between the front and back of the user such that the user is supported at an angle of 10° to 30° forwardly of vertical.

Claim 4

Apparatus as described in claim 2 wherein said flotation means comprises a plurality generally planar buoyant members having a generally uniform thickness and extending from the hips of the user to the shoulder of the user along the front and back of the torso of the user.

Claim 5

Apparatus as defined in claim 1 further comprising a vest-like member encasing said flotation means and operably attached to said restraining means with said vest-like member being adjustable in girth.

Claim 6

Apparatus as defined in claim 4 wherein said restraining means comprises a strap extending between the user's legs and detachably affixed to said vest-like member.

Claim 7

Apparatus for use in performing within a body of water exercise movements corresponding to a land-based running activity comprising: (a) a vest-like member worn by the user and extending from the shoulders of the user to the hips of the user; (b) flotation means enclosed within said vest-like member for imparting a predetermined level of buoyancy to the user such that the user is supported in water with his body submerged to a point above the shoulders, said flotation means being constructed to exert a greater buoyant force on the rear of the user than the front of the user so as to support said user in an upright position inclined forwardly of vertical by less than approximately 30°, which position corresponds to that assumed in a land-based running activity; and (c) restraining means attached to said vest-like member for preventing longitudinal motion of said vest-like member along the torso of the said user.

Claim 8

Apparatus for use in performing within a body of water exercise movements corresponding to a land-based running activity comprising: (a) a vest-like member worn by the user and extending from the shoulders of the user to the hips of the user; (b) flotation means enclosed within said vest-like member for imparting a predetermined level of buoyancy to the user such that the user is supported in water with his body submerged to a point above the shoulders, said flotation means being constructed to exert a greater buoyant force on the rear of the user than the front of the user so as to support said user in an upright position inclined forwardly of vertical by less than approximately 30°, which position corresponds to that assumed in a land-based running activity; and (c) restraining means attached to said vest-like member for preventing longitudinal motion of said vest-like member along the torso of the said user.

Claim 9

Apparatus as defined in claim 6 wherein the buoyant force exerted by said flotation means is proportionally divided to support said user at a forward inclination between 10° and 30° from vertical.

Claim 10

Apparatus as defined in claim 6 wherein said vest-like member and said flotation means have a combined thickness of approximately one-sixteenth inch beneath the arms of the user, whereby the user is provided unrestricted arm motion adjacent the body of the user.

Claim 11

Apparatus as defined in claim 6 wherein said vest-like member is adjustable in girth to substantially conform to the torso of the user.

Claim 12

Apparatus as defined in claim 6 wherein said restraining means comprises a strap-like member extending between the legs of the user and detachably affixed to said vest.

Claim 13

Apparatus as defined in claim 6 wherein said flotation means comprises generally planar panels of buoyant material having a substantially uniform thickness and extending from the hips of the user upwards to the shoulders of the user.

Claim 14

Apparatus for use in performing within a body of water movements corresponding to a land-based running activity, comprising: (a) a vest-like member extending from the shoulders of a user to the hips thereof and adapted to substantially conform to the torso of the user without restricting the movement of the user's arms or legs; (b) a rear flotation element contained within said vest-like member and positioned along the back of the user; (c) a front flotation element contained within said vest-like member and positioned along the front of the user, said front flotation element providing sufficiently less buoyant force than said rear flotation element so that the user is supported by said vest at an inclination forward of vertical of less than approximately 30°, said front and rear flotation elements having a combined buoyant force calculated to support the user with his body submerged in water to a level above the shoulders and in a generally upright position corresponding to the position assumed by the body in a land-based running activity; and (d) means passing between the legs of the user and attached to said vest for restraining said vest from upward motion along the torso of the user.

Claim 15

Apparatus for use in performing within a body of water movements corresponding to a land-based running activity, comprising: (a) a vest-like member extending from the shoulders of a user to the hips thereof and adapted to substantially conform to the torso of the user without restricting the movement of the user's arms or legs; (b) a rear flotation element contained within said vest-like member and positioned along the back of the user; (c) a front flotation element contained within said vest-like member and positioned along the front of the user, said front flotation element providing sufficiently less buoyant force than said rear flotation element so that the user is supported by said vest at an inclination forward of vertical of less than approximately 30°, said front and rear flotation elements having a combined buoyant force calculated to support the user with his body submerged in water to a level above the shoulders and in a generally upright position corresponding to the position assumed by the body in a land-based running activity; and (d) means passing between the legs of the user and attached to said vest for restraining said vest from upward motion along the torso of the user.

Claim 16

Apparatus as defined in claim 12 wherein said front and rear flotation elements support the user at an angle of between 10° and 30° forward of vertical.

Claim 17

Apparatus as defined in claim 12 wherein said vest includes side portions beneath the arms of said wearer with said side portion having a thickness of approximately one-sixteenth of an inch.
