Abstract

A safety hose apparatus delivers water from a standard threaded hose bib to an appliance or plumbing fixture. The apparatus includes an outer hose and an inner hose that extends through the outer hose. A first threaded connector is rotatably attached to the outer hose and is in communication with the inner hose. The first threaded connector is threadably engagable with the spout to communicably connect the inner hose to the hose bib. A second threaded connector is rotatably attached to the outer hose and is in communication with the second end of the inner hose. The second threaded connector is threadably engagable with the inlet to communicably connect the inner hose to the inlet. A first closure is engaged with the first end of the outer hose and a second closure is engaged with a second end of the outer hose for sealing the space between the inner and outer hoses and retaining within the space water leaking through a rupture in the inner hose. The first threaded connector is peripherally exposed by the first end of the outer hose sufficiently to prevent unhindered rotation of the first threaded connector about the outer hose so that the first connector may be threadably with and disengaged from the spout and the second threaded connector is peripherally exposed by the second end of the outer hose sufficiently to permit unhindered rotation of the second threaded connector relative to the outer hose so that the second connection may be threadably engaged with and disengaged from the inlet.

Dependent claims

A safety hose apparatus for delivering water from a threaded spout of a hose bib to a threaded appliance inlet, said apparatus comprising:

an outer hose;
an inner hose extending through said outer hose such that a space is formed between said inner and outer hoses;
a first pipe communicably connected to a first end of said inner hose;
a first threaded connector rotatably and sealably attached to said outer hose at a first end of said out hose and communicating with said first pipe, said first threaded connector being threadably engagable with the threaded spout to communicably connect said first pipe and said inner hose to the hose bib;
a second pipe communicably connected to a second end of said inner hose;
a second threaded connector rotatably and sealably attached to said outer hose at an opposite, second end of said outer hose and communicating with said second pipe, said second threaded connector being threadably engagable with the threaded inlet to communicably connect said second pipe and said inner hose to the inlet;
and
a first closure engaged with said first end of said outer hose, and a second closure engaged with said second end of said outer hose for sealing the space between said inner and outer hoses, at least when said first and second connectors are engaged with the spout and appliance inlet respectively, to retain within said space water leaking through a rupture in said inner hose;
said first threaded connector being peripherally exposed by said first end of said outer hose sufficiently to permit unhindered rotation of said first threaded connector about said outer hose so that said first connector may be threadably engaged with and disengaged from the spout, and said second threaded connector being peripherally exposed by said second end of said outer hose sufficiently to permit unhindered rotation of said second threaded connector relative to said outer hose so that said second connector may be threadably engaged with and disengaged from the inlet.

An apparatus for delivering water from a threaded spout of a hose bib to a threaded appliance, said apparatus comprising:

an outer conduit;
an inner conduit extending through said outer conduit such that a space is formed between said inner and outer conduits;
a first threaded connector rotatably and sealably attached to said outer conduit at a first end of said outer conduit and in communication with said inner conduit, said first threaded connector being threadably engagable with the threaded spout to communicably connect said inner hose to the hose bib;
a second threaded connector rotatably and sealably attached to said outer conduit at an opposite, second end of said conduit and communicably attached with said inner conduit, said second threaded connector being threadably engagable with the threaded inlet to communicably connect said inner conduit to the inlet;
a first closure engaged with said first end of said outer conduit and a second closure engaged with said second end of said outer conduit for sealing the space between said inner and outer conduits, at least when said first and second connector are engaged with the spout and appliance inlet respectively, to retain within said space water leaking through a rupture in said inner conduit;
said first threaded connector being peripherally exposed by said first end of said outer conduit sufficiently to permit unhindered rotation of said first threaded connector about said outer conduit so that said first connector may be threadably engaged with and disengaged from the spout, and said second threaded connector being peripherally exposed by said second end of said outer conduit sufficiently to permit unhindered rotation of said second threaded connector relative to said outer conduit so that said second connector may be threadably engaged with and disengaged from the inlet.
