Kink, crush, and burst resistant flexible hose

摘要

The flexible hose (10) of the present invention is crush resistant. The hose design of the present invention is particularly applicable to garden hoses for the delivery of water. The present invention discloses a hose having a longitudinal axis (30) and a lumen (28) for conveyance of a fluid comprising an inner tubular layer, a fabric reinforcing layer wherein said fabric reinforcing layer (22) is comprised of a first plurality of reinforcing cords (56) which extend spirally through the hose and are substantially parallel to each other and a second plurality of reinforcing cords (57) which extend spirally through the hose (10) and are substantially parallel to each other, wherein the first plurality of reinforcing cords (56) are oriented at an angle α which is within the range of 20° to 50° of the longitudinal axis (30) of the hose, and wherein the second plurality (57) of reinforcing cords are oriented at an angle β which is within the range of 60° to 85° of the longitudinal axis (30) of the hose, wherein the angle α and the angle β are mutually opposite with respect to the longitudinal axis (30) of the hose, an outer tubular layer, and at least one reinforcing strip (12,14,16) which is at least partially embedded within the outer tubular layer and helically wound in the direction of β with respect to the orientation of the reinforcing cords (57) and a pitch about the lumen (28) of said hose (10).
