Abstract

Abstract A hose coupling assembly (10) of the type adapted to secure a hose (12) to a fitting. The assembly (10) includes a hose (12). A coupling member (16) is provided which includes an insert portion (18) for disposition within an opening (14) in the hose (12). An inner collar (28) is positioned about the exterior of the hose (12) and radially spaced from the insert portion (18) of the coupling member (16). An outer collar (38) is positioned over the inner collar (28) to provide an inwardly directed force thereto. The inner collar (28) has a plurality of slots (34) therein. The slots (34) compress in response to the inwardly directed force from the outer collar (38) to reduce the inner diameter of the inner collar (28) to thereby provide radial compression completely about the hose (12). The compression prevents removal of the coupling member (16) from the hose (12).

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 222 words
A conduit coupling assembly (10) of the type connecting a conduit (12) with a fitting comprising: a conduit (12); coupling means (16) for connecting said conduit with the fitting and including an insert portion (18) having a plurality of barbs (20) thereon, said insert portion disposed within said conduit (12) and having a cylindrical bore (19) therethrough; an outer collar (38) disposed about said conduit (12) having an inner tapered surface (40) for providing a radially inwardly directed force toward said conduit (12); and annular inner collar means (26) comprising an inner tubular collar (28) including a front portion (30) and a rear portion (32) and having a plurality of slots (34) alternatively extending longitudinally from said front (30) and said rear (32) portions circumferentially about said inner tubular collar, said tubular collar (28) having a smooth inner surface for engaging said conduit (12) and an annular outer incline surface (36) for mating engagement with said inner tapered surface (40) of said outer collar (38) to receive said inwardly directed force from said outer collar (38) such that said force is applied about said outer incline surface (36) of said inner tubular collar (28) and said outer collar (38) provides radial compression circumferentially about said conduit (12) and said compression is directly applied over the axial length of said inner collar (28).
Claim 2
Dependent Claim 222 words
A conduit coupling assembly (10) of the type connecting a conduit (12) with a fitting comprising: a conduit (12); coupling means (16) for connecting said conduit with the fitting and including an insert portion (18) having a plurality of barbs (20) thereon, said insert portion disposed within said conduit (12) and having a cylindrical bore (19) therethrough; an outer collar (38) disposed about said conduit (12) having an inner tapered surface (40) for providing a radially inwardly directed force toward said conduit (12); and annular inner collar means (26) comprising an inner tubular collar (28) including a front portion (30) and a rear portion (32) and having a plurality of slots (34) alternatively extending longitudinally from said front (30) and said rear (32) portions circumferentially about said inner tubular collar, said tubular collar (28) having a smooth inner surface for engaging said conduit (12) and an annular outer incline surface (36) for mating engagement with said inner tapered surface (40) of said outer collar (38) to receive said inwardly directed force from said outer collar (38) such that said force is applied about said outer incline surface (36) of said inner tubular collar (28) and said outer collar (38) provides radial compression circumferentially about said conduit (12) and said compression is directly applied over the axial length of said inner collar (28).
Claim 3
Dependent Claim 42 words
An assembly as set forth in claim 25 further characterized by said coupling means (16) including a connecting portion extending longitudinally outwardly from said conduit (12) and away from said insert portion (18) for connecting said coupling means (16) to the fitting.
Claim 4
Dependent Claim 41 words
An assembly as set forth in claim 2 further characterized by said connecting portion having an annular flanged portion (22) including a shoulder surface (23) to engage said inner (28) and said outer collars (38) and to limit longitudinal movement thereof.
Claim 5
Dependent Claim 27 words
An assembly as set forth in claim 3 further characterized by said connecting portion having a male threaded portion (24) extending longitudinally from said flanged portion (22).
Claim 6
Dependent Claim 26 words
An assembly as set forth in claim 3 further characterized by said connecting portion having a female threaded portion extending longitudinally from said flanged portion (22).
Claim 7
Dependent Claim 26 words
An assembly as set forth in claim 3 further characterized by said inner collar (28) and said outer collar (38) being comprising an organic polymeric material.
