Aquatic vacuum hose swivel cuff
First Claim
1. A hose and swivel cuff, comprising, in combination:
- a flexible blow-molded hose having substantially uniform circumferential grooves and convolutions throughout the length thereof;
a one-piece molded cuff which has a seating portion for receiving and adapted to coupled with an end portion of said hose, regardless of the point at which the hose is cut, and at least one rigid annular ring adapted to fit within one of said circumferentail grooves of said hose, said at least one annular ring being provided about the hose entrance to said seating portion of said cuff;
wherein the inner diameter of said at least one annular ring is less than the outer diameter of said circumferential convolutions of said hose, the end portion of said hose is maintained within said seating portion by said at least one annular ring being engaged within one of said circumferential grooves 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 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 corrugated end portion having circumferential grooves therein. The swivel cuff component has a seating portion for receiving the corrugated end portion of the hose and at least one annular ring adapted to fit within the circumferential grooves of the hose, the annular ring being provided about the hose entrance to the seating portion of the cuff. The corrugated end portion of the hose is maintained within the seating portion of the cuff by the annular ring being disposed within the circumferential grooves whereby the hose may be swivelably rotated within the cuff. The corrugated end portion of the hose is extruded with the continuous extrusion blow-molded hose thereby eliminating the need to weld components such as seals.
