Aquatic vacuum hose swivel cuff
First Claim
1. A hose and swivel cuff, comprising, in combination:
- a flexible blow-molded hose portion which has at least one end which terminates as a substantially right cylindrical end portion and which has a hose ring provided substantially adjacent to said cylindrical end portion whereby a circumferential groove is provided between said cylindrical end portion and said hose ring; and
a molded cuff which has a seating portion for receiving said cylindrical end portion of said hose and a rigid first annular ring adapted to fit within said circumferential groove of said hose, said first annular ring being provided about the hose entrance to said seating portion of said cuff;
wherein the inner diameter of said first annular ring is less than the outer diameter of said cylindrical end portion, the cylindrical end portion of said hose is maintained within said seating portion by said first annular ring being snap-fitted within said circumferential groove such that said hose end is locked in the longitudinal direction within said cuff, and said hose portion is swivelably rotatable within said cuff and water may seep around the outer circumference of said cylindrical end portion and into said cuff.

Abstract
An aquatic vacuum hose swivel cuff coupling comprises, in combination, a blow-molded vacuum hose and a molded swivel cuff. The hose includes one end which terminates as a right cylindrical end portion and a hose ring provided substantially adjacent to the cylindrical end portion whereby a circumferential groove is provided between the cylindrical end portion and the hose ring. The swivel cuff component has a seating portion for receiving the cylindrical end portion of the hose and an annular ring adapted to fit within the circumferential groove of the hose, the annular ring being provided about the hose entrance to the seating portion of the cuff. The cylindrical end portion of the hose is maintained within the seating portion of the cuff by the annular ring being disposed within the circumferential groove whereby the hose may be swivelably rotated within the cuff. The hose end components are extruded with the continuous extrusion blow-molded hose thereby eliminating the need to weld components such as seals.
