ABSTRACT:
A universal adaptor (10) to facilitate the connection, and retention, of a drain hose (12) with the standpipe of a household sanitary system. One end portion (11) of the drain hose (12) has an inlet cuff (15) adapted to be secured to the discharge tube (16) of a household appliance (18). The universal adaptor (10) is presented from the other end portion (11) of the drain hose (12). The universal adaptor (10) has a generally cylindrical body portion (20) which terminates in oppositely disposed proximal and distal ends (23 and 28, respectively). A passageway (21) extends axially through the body portion (20) and opens through the oppositely located proximal and distal ends (23 and 28). The proximal end (23) is adapted to be secured to the drain hose (12). The body portion (20) also has outer surfaces (25 and 26). A plurality of flexible, frustro-conical fins (30) project conically outwardly from the outer surfaces (25 and 26). The fins (30) have progressively stepped outer diameters (D.sub.A through D.sub.G), with that fin (30A) having the smallest outer diameter (D.sub.A) located on proximity to the distal end (28) and with that fin (30G) having the largest outer diameter (D.sub.G) located in proximity to proximal end (23) for engaging standpipes (13) having inner, diametral dimensions falling within a predetermined range.
