Abstract
Abstract A flotation device designed to support a person in a partially submerged position in a body of water includes a long narrow flexible main body member made of buoyant closed cell foam material. A first cylindrical float section, made of the same material, is attached to one end of the main body member. A second cylindrical section, also made of the same buoyant material, has a slot in it and slides over the second end of the main body member to frictionally engage the main body member to locate the second float section at various positions between the first and second ends of the main body member.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
116 words
A flotation device for supporting a person in a reclining or sitting position in a body of water including in combination: a flexible elongated main body member of a predetermined thickness selected to underlie the back of a person, said main body member having a length several times greater than the width thereof, made of buoyant material, and having first and second ends; a first transverse float section attached to the first end of said main body member to underlie the neck and head of a person; and a second transverse float section movably attached to said main body member between the first and second ends thereof for location at various positions along the length thereof.
Claim 2
Dependent Claim
116 words
A flotation device for supporting a person in a reclining or sitting position in a body of water including in combination: a flexible elongated main body member of a predetermined thickness selected to underlie the back of a person, said main body member having a length several times greater than the width thereof, made of buoyant material, and having first and second ends; a first transverse float section attached to the first end of said main body member to underlie the neck and head of a person; and a second transverse float section movably attached to said main body member between the first and second ends thereof for location at various positions along the length thereof.
Claim 3
Dependent Claim
72 words
The combination according to claim 1 wherein said second float section is an elongated member having a slot therein with height and width corresponding to the thickness and width of said elongated main body member for frictional engagement with said main body member to permit relative movement of said main body member through said slot to position said second float section at selected positions along the length of said main body member.
Claim 4
Dependent Claim
16 words
The combination according to claim 2 wherein said first and second float sections are cylindrical members.
Claim 5
Dependent Claim
29 words
The combination according to claim 3 wherein said first and second float sections are made of the same buoyant material of which said elongated main body member is made.
Claim 6
Dependent Claim
30 words
The combination according to claim 4 wherein said main body member has a length of between three feet and four feet and a width between four inches and eight inches.

The combination according to claim 5 wherein said buoyant material is closed cell foam material.
Claim 8
Dependent Claim
50 words
The combination according to claim 6 wherein said first and second float sections each have a length less than the length of said elongated main body member and each of said float sections are attached to said main body member at substantially the midpoint of each of said float sections.
Claim 9
Dependent Claim
19 words
The combination according to claim 1 wherein said elongated main body member is made of closed cell foam material.
Claim 10
Dependent Claim
20 words
The combination according to claim 8 wherein said first and second float sections are made of closed cell foam material.
Claim 11
Dependent Claim
14 words
The combination according to claim 1 wherein said float sections are cylindrical float sections.
Claim 12
Dependent Claim
29 words
The combination according to claim 1 wherein said first float section includes at least one elongated member attached transversely to said first end of said elongated main body member.
Claim 13
Dependent Claim
14 words
The combination according to claim 11 wherein said float sections are cylindrical float sections.
Claim 14
Dependent Claim
29 words
The combination according to claim 12 wherein said first and second float sections are made of the same buoyant material of which said elongated main body member is made.
Claim 15
Dependent Claim
72 words
The combination according to claim 13 wherein said second float section is an elongated member having a slot therein with height and width corresponding to the thickness and width of said elongated main body member for frictional engagement with said main body member to permit relative movement of said main body member through said slot to position said second float section at selected positions along the length of said main body member.
Claim 16
Dependent Claim
50 words
The combination according to claim 1 wherein said first and second float sections each have a length less than the length of said elongated main body member and each of said float sections are attached to said main body member at substantially the midpoint of each of said float sections.
Claim 17
Dependent Claim
30 words
The combination according to claim 1 wherein said main body member has a length of between three feet and four feet and a width between four inches and eight inches.
Claim 18
Dependent Claim
50 words
The combination according to claim 16 wherein said first and second float sections each have a length less than the length of said elongated main body member and each of said float sections are attached to said main body member at substantially the midpoint of each of said float sections.
Claim 19
Dependent Claim
29 words
The combination according to claim 17 wherein said first and second float sections are made of the same buoyant material of which said elongated main body member is made.
Claim 20
Dependent Claim
15 words
