Abstract
Abstract A strapless ring buoy and method of making the same in which an elongated rope is formed into a circle having a plurality of spaced inwardly directed loops. The rope is placed around a mold in which the ring body portion of the buoy is to be molded, with the loops extending across the midportion of the mold. The loops are coated with a heat-reacting adhesive composition so that the expanded polystyrene foam material forming the ring is bonded to the loops at the same time and through the same means used for molding the ring. The loops are held within the ring securely to attach the rope without straps or other fastening means of any kind either inside or outside of the ring. The portions of the rope between the loops substantially encircle the ring. The strands forming the loops may be crossed and/or passed through eyelet fittings to provide added strength.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
143 words
A method of making a strapless ring buoy comprising forming an elongated rope into a circle having a plurality of spaced inwardly directed loops, placing said rope around a mold in which the ring body portion of said ring buoy is to be molded, with said loops being disposed within said mold, coating said loops with a heat-reacting adhesive composition, applying heat to said mold to form a ring of expanded polystyrene foam material or the like around said loops so that said loops are enclosed within said ring and securely bonded to said ring at the time and through the same means used to mold said ring, to secure said rope to said ring without straps or other fastening means of any kind either within or outside of said ring, the portions of said rope between said loops substantially encircling said ring.
Claim 2
Independent Claim
143 words
A method of making a strapless ring buoy comprising forming an elongated rope into a circle having a plurality of spaced inwardly directed loops, placing said rope around a mold in which the ring body portion of said ring buoy is to be molded, with said loops being disposed within said mold, coating said loops with a heat-reacting adhesive composition, applying heat to said mold to form a ring of expanded polystyrene foam material or the like around said loops so that said loops are enclosed within said ring and securely bonded to said ring at the time and through the same means used to mold said ring, to secure said rope to said ring without straps or other fastening means of any kind either within or outside of said ring, the portions of said rope between said loops substantially encircling said ring.
Claim 3
Dependent Claim
49 words
The structure described in claim 1, and disposing said loops in a position extending in a horizontal plane transversely across the midportion of said mold, so that said loops extend in a horizontal plane transversely across the midportion of the interior of said ring after said ring is molded.
Claim 4
Dependent Claim
40 words
The method described in claim 1, and covering the entire outer surface of both sides of said ring with a layer of polyvinyl chloride foam material or the like, and adhering said material to said ring with an adhesive composition.
Claim 5
Dependent Claim
28 words
The method described in claim 2, and crossing the strands forming each of said loops to provide added resistance to the separation of said rope from said ring.
Claim 6
Dependent Claim
45 words
The method described in claim 3, and adhesively securing beading to seal the junction along the inner and outer edges of said ring where the edges of said covering material abut, and spraying the outside of said ring buoy with vinyl material or the like.
Claim 7
Dependent Claim
106 words
A strapless ring buoy comprising a body portion in the form of a ring of expanded polystyrene foam material or the like, a rope substantially encircling the entire outer periphery of said ring, said rope having a plurality of spaced inwardly directed loops extending a substantial distance into said ring, said loops being adhesively secured within said ring by a heat-reacting adhesive composition forming a bond between said loops and said ring at the same time that said ring is formed, so that said rope is secured to said ring without straps or other fastening means of any kind either within or outside of said ring.
Claim 8
Dependent Claim
106 words
A strapless ring buoy comprising a body portion in the form of a ring of expanded polystyrene foam material or the like, a rope substantially encircling the entire outer periphery of said ring, said rope having a plurality of spaced inwardly directed loops extending a substantial distance into said ring, said loops being adhesively secured within said ring by a heat-reacting adhesive composition forming a bond between said loops and said ring at the same time that said ring is formed, so that said rope is secured to said ring without straps or other fastening means of any kind either within or outside of said ring.
Claim 9
Dependent Claim
26 words
A ring buoy as described in claim 6, in which said loops extend in a horizontal plane transversely across substantially the entire midportion of said ring.
Claim 10
Dependent Claim
35 words
A ring buoy as described in claim 7, in which the strands of said rope forming each of said loops are crossed to provide added resistance to the separation of said rope from said ring.
Claim 11
Dependent Claim
62 words
A ring buoy as described in claim 6, the entire outer surface of both sides of said ring being covered with a layer of polyvinyl chloride foam material, beading sealing the joints along the inner and outer edges of said ring where the edges of said covering material abut, and a coating of vinyl material covering the outside of said ring buoy.
