Abstract
A fluid conduit includes a flexible member having a tubular wall and a plurality of geometric segments located adjacent to the tubular wall. The geometric segments are disposed about a central axis of the conduit and spaced apart relative to each other to define a gap therebetween. The gap is sized to be closed by contact between adjacent geometric segments upon a predetermined flexure of the flexible member. A method of forming the conduit includes forming a flexible member with a tubular wall and forming a plurality of grooves about the central axis in the tubular wall. The geometric segments in one embodiment are formed from the intersections of a first plurality of helical grooves formed at a first angle relative to the central axis and a second plurality of helical grooves formed at a second angle mutually opposite from the first angle.
Description
[0001] This application claims the benefit of US Provisional Application No. 61 / 787,749, filed March 15, 2013, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to fluid conduits, and more particularly to flexible hoses. Background technique [0003] Flexible hoses are widely used in various industrial, household and commercial applications. One commercial application of hose is a garden or water hose for domestic or industrial use. For example, hoses are used to water lawns, trees, shrubs, flowers, vegetable plants, vines, and other types of vegetation, to clean houses, buildings, boats, equipment, vehicles, and animals, or to transfer between fluid sources and instruments . For example, an appliance may be a sink, a faucet, etc. that provide cold or hot water. Another commercial application for hoses is automotive hoses for fuel delivery, gasoline, and other petroleum-based products. Ano...
