Patent ID: 7387317

Claim:
A reinforced hose coupling, said reinforced hose coupling comprising: an annular inner sleeve having a first end, a second end opposite said first end, and a pair of annular upset beads therebetween, said annular inner sleeve further having an inner diameter and an outer diameter thereon, said outer diameter having at least one projection thereon; a hose having an inner diameter positioned over said outer diameter of said annular inner sleeve, said at least one projection of said annular inner sleeve interlocking with said hose to resist axial movement of said hose relative to said reinforced hose coupling; an annular outer sleeve having a terminating end sandwiched between said pair of annular upset beads of said annular inner sleeve to prevent axial movement relative to said annular inner sleeve, said annular outer sleeve further having an inner diameter circumscribing said hose, said inner diameter of said annular outer sleeve further including at least one depression therein formed by a crimping operation, said at least one depression defining an area of peak crimp force of a predetermined longitudinal length and interlocking with said hose to further resist axial movement of said hose relative to said reinforced hose coupling; and at least one reinforcing ring positioned within said inner diameter of said annular inner sleeve, said at least one reinforcing ring having a predetermined longitudinal length less than said predetermined longitudinal length as defined by said area of peak crimp force, whereby said at least one reinforcing ring provides localized support along said predetermined longitudinal length of said at least one depression to resist deformation of said annular inner sleeve during said crimping operation.
