Abstract
Abstract A flotation device for supporting a person in water comprises an elongate tubular frame including at least one body-support member, and front and rear float assemblies mounted on the frame. The rear float assembly comprises two float elements spaced apart transversely of the elongate frame, and the float elements are so disposed that, when the device is floating in the water, the body-support member is below water level, so that a person using the device is partly in the water.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
171 words
A flotation device for supporting a person in water comprising an elongate frame including at least one body-support member, and front and rear float assemblies mounted on the frame, at least one of said float assemblies comprising two float elements spaced apart transversely of the elongate frame, and locating means on the frame providing a push-fit connection between the float elements and the frame, whereby the float elements are easily attachable and detachable to and from the frame by hand, each float element comprising a body of buoyant material connected to the elongate frame by a respective mounting element, each mounting element being shaped to define an aperture into which said body of buoyant material is received, each mounting element being round aluminum tubing bent into a loop to define said aperture, each body of buoyant material including notches between two portions of greater cross-sectional area, the buoyant material being retained in the aperture by forcing it through the loop of bent aluminum tubing until the tubing snaps into the notches.
Claim 2
Dependent Claim
171 words
A flotation device for supporting a person in water comprising an elongate frame including at least one body-support member, and front and rear float assemblies mounted on the frame, at least one of said float assemblies comprising two float elements spaced apart transversely of the elongate frame, and locating means on the frame providing a push-fit connection between the float elements and the frame, whereby the float elements are easily attachable and detachable to and from the frame by hand, each float element comprising a body of buoyant material connected to the elongate frame by a respective mounting element, each mounting element being shaped to define an aperture into which said body of buoyant material is received, each mounting element being round aluminum tubing bent into a loop to define said aperture, each body of buoyant material including notches between two portions of greater cross-sectional area, the buoyant material being retained in the aperture by forcing it through the loop of bent aluminum tubing until the tubing snaps into the notches.
Claim 3
Dependent Claim
28 words
A flotation device according to claim 1, wherein the two transversely spaced float elements are separately formed and are connected to the elongate frame by rear mounting elements.
Claim 4
Dependent Claim
35 words
A flotation device according to claim 1, wherein the front float assembly comprises a single float element disposed on the longitudinal axis of the frame and connected to the frame by a front mounting element.
Claim 5
Dependent Claim
17 words
A flotation device according to claim 1, wherein the buoyant material comprises cross-linked closed cell polyethylene foam.
Claim 6
Dependent Claim
24 words
A flotation device according to claim 1, wherein the body-support member comprises a substantially flat panel on which a person may sit or lie.
Claim 7
Dependent Claim
40 words
A flotation device according to claim 5, wherein the body-support member further comprises an additional panel disposed at an angle to the first said panel for use as a back rest by a person sitting on the first said panel.
Claim 8
Dependent Claim
39 words
A flotation device according to claim 2, wherein the rear mounting elements are adjustably mounted on the elongate frame whereby the positions of the float elements may be adjusted with respect to one another and to the body-support member.
Claim 9
Dependent Claim
48 words
A flotation device according to claim 7, wherein the rear mounting elements are adjustable so as to bring the rear float elements closer to or further from the body-support member so as to adjust the distance below water level of the body-support member when the device is floating.
Claim 10
Dependent Claim
29 words
A flotation device according to claim 8, wherein the rear mounting elements are also adjustable so as to move the rear float elements towards or away from one another.
Claim 11
Dependent Claim
36 words
A flotation device according to claim 3, wherein the front mounting element is adjustably mounted on the elongate frame whereby the position of the front float element may be adjusted with respect to the body-support member.
Claim 12
Dependent Claim
20 words
A flotation device according to claim 1, and incorporating laterally extending hand grips in addition to the aforesaid body-support member.
Claim 13
Dependent Claim
28 words
A flotation device according to claim 1, wherein the elongate frame includes two body-support members symmetrically disposed on either side of the central longitudinal axis of the frame.
Claim 14
Dependent Claim
21 words
A flotation device according to claim 1, further including a sail mounting device and a rudder mounted on the elongate frame.
