Abstract

The present invention is a safety hose system for use in delivering water from a water supply source to an inlet connector of a washing machine. In one embodiment, the system comprises a first connector engageable with the inlet connector of the washer machine and a second connector engageable with the water supply source. The system further comprises a first hose having first and seconds end connected to the first and second connectors, respectively. The system further comprises a second hose disposed concentrically and sealed about the first hose and extending from the first connector to the second connector. The system further comprises a sealing material. The first and second ends of the second hose are molded to the first and second connector, respectively, by the sealing material to form an unitary one piece structure. The system may further comprise an over-spill portion formed by said second hose being disposed about the first hose. The over-spill portion comprises a water reactive material which will change the color of any water entering into the over-spill portion. The system further comprises a third hose having a first end engaged with the second hose and in communication with the over-spill portion. The third hose is made from a transparent material such that the color of any water passing there through can be visually observed. In operation, if the first hose should become damaged any water flowing through the first hose will be passed into the over-spill portion and into the third hose where it is safely discarded.

Dependent claims

A safety hose system for use in delivering water from a water supply connector to an inlet connector of a washing machine, the safety hose system comprising:

(a) an inner hose having first and second end portions and an outside surface;
(b) an outer hose having first and second end portions and an inside surface;
(c) a first connector having a first engagement portion engageable with the inlet connector of the washing machine and a first tube member having a first end portion extending outward from said first connector, said first connector being rotatable about said first tube member;
(d) a second connector having a second engagement portion engageable with the water supply connector and a second tube member having a second end portion extending outward from said second connector, said second connector being rotatable about said second tube member;
(e) said first and second end portions of said inner hose being engaged with said first and second end portions of said first and second tube members, respectively;
(f) first and second plug members each having first and second end portions;
(g) said first end and second portions of said outside hose being engaged with said first and second plug members, respectively;
(h) said first plug member being disposed about said first tube member such that said second end portion of said first plug member ends extends substantially to said first end portion of said first tube member;
(i) said second plug member being disposed about said second tube member such that said second end portion of said second plug member ends extends substantially to said first end portion of said second tube member;
and
(j) a water leakage chamber having a first portion and a second portion formed by said second end portion of said first plug member, said outside surface of said inner hose, said inside surface of said outside hose, said water leakage chamber, said water leakage chamber does not substantially extend into said first and second plug members.
