Abstract
Abstract A shape retention hose contruction and method of making the same are provided, the hose construction comprising a length of flexible tubular hose formed mainly of polymeric material and having opposite end portions and an intermediate body portion that defines internal and external peripheral surfaces of said hose, and a shape retention unit carried by the hose and being adapted to generally retain the shape of the hose construction when the hose and its carried shape retention unit are jointly bent into a particular shape, the shape retention unit comprising a deformable tubular member having opposed ends and a continuous sidewall between the ends that defines an internal and external peripheral surface of the tubular member, the hose and tubular member being telescoped together with the surfaces of the tubular member being disposed closely adjacent the surfaces of the hose.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
In a shape retention vehicle radiator hose construction comprising a length of flexible tubular hose formed mainly of polymeric material and having opposite end portions and an intermediate body portion that defines internal and external peripheral surfaces of said hose, said end portions comprising mounting cuffs of said hose construction, said body portion being corrugated, and shape retention means carried by just said body portion of said hose and being adapted to generally retain the shape of said hose construction when said hose and its carried shape retention means are jointly bent into a particular shape, the improvement wherein said shape retention means comprises a deformable metallic corrugated tubular member having opposed ends and a continuous sidewall between said ends that is thinner than said body portion of said hose and that defines internal and external peripheral surfaces of said tubular member and corrugations of said body portion of said hose, said hose and said tubular member being telescoped together with one of said surfaces of said tubular member being disposed closely adjacent one of said surfaces of said hose.
Claim 2
Dependent Claim
