Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
A flexible hose comprising: a polymeric tube; a plurality of circumferentially spaced ribs integral with and radially extending from the exterior of the tube; a reinforcement of oppositely wound textile strands twined over the tube, the strands deforming portions of the ribs at points of contact therewith, undeformed portions of the ribs extending radially past the strands, and the ribs deformed to a point near the tube whereby the ribs mechanically hold and substantially maintain the strands of the reinforcement in spaced relationship on the tube; and a cover formed over the tube, reinforcements, and ribs, the undeformed portions of the ribs extending into portions of the cover mechanically interlocking their width.
Claim 2
Dependent Claim
112 words
A flexible hose comprising: a polymeric tube; a plurality of circumferentially spaced ribs integral with and radially extending from the exterior of the tube; a reinforcement of oppositely wound textile strands twined over the tube, the strands deforming portions of the ribs at points of contact therewith, undeformed portions of the ribs extending radially past the strands, and the ribs deformed to a point near the tube whereby the ribs mechanically hold and substantially maintain the strands of the reinforcement in spaced relationship on the tube; and a cover formed over the tube, reinforcements, and ribs, the undeformed portions of the ribs extending into portions of the cover mechanically interlocking their width.
Claim 3
Dependent Claim
28 words
A hose as set forth in claim 1 wherein the ribs have a cross-section shape that is generally triangular with an apex oriented substantially radially from the tube.
Claim 4
Dependent Claim
29 words
A hose as set forth in claim 1 wherein the ribs have a maximum width that is generally equal to or less than the strand gauge of the reinforcement.
Claim 5
Dependent Claim
19 words
A hose as set forth in claim 1 wherein the ribs are substantially equally circumferentially spaced around the tube.
Claim 6
Dependent Claim
109 words
A flexible hose of the type having a tube and a cover sandwiching an oppositely spiralled twined textile reinforcement of yarn strands in which the improvement comprises: at least one rib integral with and extending generally radially from the exterior of the tube, the rib deformed by the reinforcement at each point of contact therewith, undeformed portions of the rib extending radially past the strands, and the rib deformed to a point near the tube; whereby the rib mechanically holds and substantially maintains the strands of reinforcement in fixed spaced relationship with the tube, the undeformed portions of the ribs extending into portions of the cover mechanically interlocking therewith.
Claim 7
Dependent Claim
109 words
A flexible hose of the type having a tube and a cover sandwiching an oppositely spiralled twined textile reinforcement of yarn strands in which the improvement comprises: at least one rib integral with and extending generally radially from the exterior of the tube, the rib deformed by the reinforcement at each point of contact therewith, undeformed portions of the rib extending radially past the strands, and the rib deformed to a point near the tube; whereby the rib mechanically holds and substantially maintains the strands of reinforcement in fixed spaced relationship with the tube, the undeformed portions of the ribs extending into portions of the cover mechanically interlocking therewith.
