Abstract
Abstract Apparatus for use in hydro-therapy comprises a pair of parallel rods 2 extending between rigid flotation bodies 4. Each rod 2 is formed at each end with a vertical extension 6 passing through a slot 8 in the respective body 4. Each extension 6 is screw threaded and carries clamping nuts 12 and 14 respectively above and below the upper and lower surfaces of the body 4. Adjustment of the spacing between the rods 2 is obtained by relative movement of the extensions 6 along the slots 8 and vertical adjustment of the rods 2 is obtained by nuts 12 and 14.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
Hydrotherapy apparatus for supporting a patient in a body of water comprising a pair of flotation bodies, a pair of parallel bars extending substantially horizontally between the flotation bodies and having vertically oriented end portions extending upwardly through the flotation bodies such that a patient may be supported in a generally vertical position in the body of water by the parallel bars disposed under the armpits of the patient and with the flotation bodies being disposed in front of and behind the patient and adjustable means for securing said bars to said flotation bodies whereby the spacing between said bars is adjustable to position the bars under the armpits so that the patient may be supported in the body of water between the flotation bodies.
Claim 2
Dependent Claim
125 words
Hydrotherapy apparatus for supporting a patient in a body of water comprising a pair of flotation bodies, a pair of parallel bars extending substantially horizontally between the flotation bodies and having vertically oriented end portions extending upwardly through the flotation bodies such that a patient may be supported in a generally vertical position in the body of water by the parallel bars disposed under the armpits of the patient and with the flotation bodies being disposed in front of and behind the patient and adjustable means for securing said bars to said flotation bodies whereby the spacing between said bars is adjustable to position the bars under the armpits so that the patient may be supported in the body of water between the flotation bodies.
Claim 3
Dependent Claim
36 words
Apparatus according to claim 1 wherein said securing means is such as also to permit adjustment of said bars in relation to said flotation bodies in a direction perpendicular to the common plane of said bars.
Claim 4
Dependent Claim
53 words
Apparatus according to claim 1, wherein each said end portion is formed with screw-threaded portions, said apparatus including pairs of nuts engaging corresponding threaded portions of said end portions, each said pair of nuts when tightened engaging opposite faces of said respective flotation body whereby to clamp the respective end portion in position.
Claim 5
Dependent Claim
63 words
Apparatus according to claim 3 wherein each said flotation body has a central, flat-surfaced recess and two narrower, deeper outer flat-surfaced recesses formed in its edge adjacent said parallel bars and said nuts which engage said edge of said respective flotation body adjacent said parallel bars, each have a transverse dimension in one direction only slightly greater than the thickness of said extension.
Claim 6
Dependent Claim
33 words
Apparatus according to claim 1 wherein each said flotation body is formed with flat surfaces joining one another substantially at right angles to form square corners whereby to promote water turbulence during use.
Claim 7
Dependent Claim
25 words
Apparatus according to claim 5 wherein each said flotation body is formed in its edge adjacent said parallel bars with at least one flat-surfaced recess.
Claim 8
Dependent Claim
22 words
Apparatus according to claim 6 wherein each said flotation body has a central, flat-surfaced recess and two narrower, deeper outer flat-surfaced recesses.
