Abstract
A portable floatation apparatus comprising a platform, a ramp, and a buoyancy structure non-removably attached to the platform. At least one buoyancy structure may be removably attached under the platform to adjust the buoyancy of the floatation apparatus. The platform may be perforated to allow liquids to drain through the perforations. A membrane structure may be removably attached to a bottom side of the floatation apparatus to capture any liquid draining through the perforations. The floatation apparatus is adapted to support an animal, such as a pet dog or a pet cat, over the body of water.
Claims28
A floatation apparatus, comprising:
- a platform structure, wherein the platform structure comprises perforations adapted to drain a liquid from the platform structure;
- a permanent buoyancy structure physically attached to a first side of the platform structure;
- and
- at least one removable buoyancy structure removably attached to the platform apparatus, wherein the floatation apparatus is portable, wherein the floatation apparatus is adapted to float on water, wherein the platform structure is adapted to support a pet over the water;
- and a membrane structure removably attached to a bottom side of the floatation apparatus, wherein the membrane structure is adapted to capture the liquid draining through the perforations.
A flotation apparatus, comprising:
- a platform having an upper surface, a lower surface, and a perimeter;
- a buoyancy structure having a top surface and a perimeter, wherein the buoyancy structure is non-removably attached to the platform along the perimeter of the platform so that the upper surface of the platform is recessed with respect to the top surface of the buoyancy structure;
- a plurality of nested endless tubular structures extending proximate the perimeter of the platform, wherein each endless tubular structure is buoyant and removably attached to the lower surface of the platform, wherein the largest of the endless tubular structures is adjacent the non-removably attached buoyancy structure and has a perimeter less than or equal to the perimeter of the platform, wherein each succeeding adjacent tubular structure has a smaller perimeter than a preceding endless tubular structure.
