Abstract
A hose with connector end fittings for carrying pressurized fluid having longitudinally displaced internal ribs. These ribs run along inside walls of the hose to prevent flow termination due to kinking or compression.
Claims16
A kink resistant flexible plastic or rubber hose for spraying water having opposite open ends for the delivery of pressurized water therethrough comprising:
- a hose having an inside wall surface and an outside wall surface, said inside wall surface having integrally molded therewith a plurality of radially spaced ribs, said ribs extending substantially continuously longitudinally between said open ends, said hose having sufficient flexibility to be double-backed upon itself to form a kink, said plurality of ribs extend only a short distance from the inside wall surface allowing for inside wall surface areas to provide an opening for said pressurized water when said kink is formed, said ribs adapted to provide a plurality of functions including resistance to hose kinking, water delivery through the hose when kinked and equalization of water pressure on both sides of said kink causing the hose to unkink and straighten itself, said ribs occupying about 3% of the internal volume of the hose,
- one said hose end for coupling to a pressurized water supply for delivery of water under pressure through said hose and the other hose end for coupling to a flow restricting device for spraying a pressurized stream of water that provides sufficient back pressure in said hose for said equalization of water pressure on both sides of the kink to cause said hose to unkink and straighten itself for said delivery of water therethrough.
A kink resistant flexible plastic or rubber household water hose for spraying water having opposite open ends for the delivery of pressurized water therethrough comprising:
- a hose having an inside wall surface and an outside wall surface, said inside wall surface having integrally molded therewith a plurality of radially spaced ribs, said ribs extending substantially continuously longitudinally between said open ends, said hose having sufficient flexibility to be double backed upon itself to form a kink, said plurality of ribs extend only a short distance from the inside wall surface allowing for inside wall surface areas to provide an opening for said pressurized water when said kink is formed, said ribs adapted to provide a plurality of functions including resistance to hose kinking, water delivery through the hose when kinked and equalization of water pressure on both sides of said kink causing the hose to unkink and straighten itself, said ribs occupying about 3% of the internal volume of the hose,
- one said hose end for coupling to a pressurized water supply for delivery of water under pressure through said hose and the other hose end for coupling to a spray nozzle for spraying a pressurized stream of water that provides sufficient back pressure in said hose for said equalization of water pressure on both sides of the kink to cause said hose to unkink and straighten itself for said delivery of water therethrough.
