Recreational flotation device and method of manufacturing same
This invention relates to recreational flotation devices, and particularly to floating mattresses or lounges, and to a method for manufacturing same.
1. A recreational flotation device, comprising:
an inner member having a first end and a second end;
a first buoyant member attached to the first end of the inner member, the first buoyant member comprising:
a first sheet having a first and a second peripheral portion;
a second sheet having a first and a second peripheral portion; and
a single welding seam fusing the first peripheral portions of the first and second sheets, and further fusing the second peripheral portions of the first and second sheets and the first end of the inner member, wherein the first end of the inner member is positioned between the second peripheral portions of the first and second sheets of the first buoyant member; and
a second buoyant member attached to the second end of the inner member, the second buoyant member comprising:
a first sheet, separate and distinct from the first and second sheets of the first buoyant member, having a first and a second peripheral portion;
a second sheet, separate and distinct from the first and second sheets of the first buoyant member, having a first and a second peripheral portion; and
a single welding seam fusing the first peripheral portions of the first and second sheets, and further fusing the second peripheral portions of the first and second sheets and the second end of the inner member, wherein the second end of the inner member is positioned between the second peripheral portions of the first and second sheets of the second buoyant member.
2. The recreational flotation device of claim 1 , wherein each of the first buoyant member and the second buoyant member comprises an air-impermeable material.
3. The recreational flotation device of claim 1 , wherein each of the first buoyant member and the second buoyant member comprises PVC.
4. The recreational flotation device of claim 1 , wherein the first sheet of the first buoyant member and the second sheet of the first buoyant member are substantially the same shape and size.
5. The recreational flotation device of claim 1 , wherein the first sheet of the second buoyant member and the second sheet of the second buoyant member are substantially the same shape and size.
6. The recreational flotation device of claim 1 , wherein the first end of the inner member is positioned between the first peripheral portion of the first sheet of the first buoyant member and the first peripheral portion of the second sheet of the first buoyant member.
7. The recreational flotation device of claim 1 , wherein the second end of the inner member is positioned between the first peripheral portion of the first sheet of the second buoyant member and the first peripheral portion of the second sheet of the second buoyant member.
8. The recreational flotation device of claim 1 , wherein the first buoyant member further comprises an inflation valve positioned in the first sheet of the first buoyant member.
9. The recreational flotation device of claim 1 , wherein the second buoyant member further comprises an inflation valve positioned in the first sheet of the second buoyant member.
10. The recreational flotation device of claim 1 , wherein the inner member comprises a mesh material.
11. A method of manufacturing a recreational flotation device comprising a first buoyant member and a second buoyant member attached to an inner member, the method comprising:
aligning first and second peripheral portions of a first sheet with first and second peripheral portions of a second sheet;
positioning a first end of the inner member between the second peripheral portions of the first and second sheets;
welding the first sheet to the second sheet to form the first buoyant member, such that the formed first buoyant member comprises a continuous welding seam continuing between the first peripheral portions of the first and second sheets and between the second peripheral portions of the first and second sheets and the first end of the inner member, thereby attaching the first and second sheets to each other and to the first end of the inner member;
aligning first and second peripheral portions of a third sheet with first and second peripheral portions of a fourth sheet;
positioning the second end of the inner member between the second peripheral portions of the third and fourth sheets; and
welding the third sheet to the fourth sheet to form the second buoyant member, wherein the second buoyant member is spaced apart from the first buoyant member, such that the formed second buoyant member comprises a continuous welding seam continuing between the first peripheral portions of the third and fourth sheets and between the second peripheral portions of the third and fourth sheets and the second end of the inner member, thereby attaching the third and fourth sheets to each other and to the second end of the inner member.
12. The method of claim 11 , wherein the inner member comprises a mesh material.
