Abstract
A coupling having an extending repositionable discharge tube for engagement with a discharge hose is mechanically lockably attachable to either of two different conventional waste water discharge outlets mounted on a recreational vehicle. Each of the waste water discharge outlets includes a set of four equiangularly spaced dogs and the set of dogs on each discharge outlet is differently configured. The coupling includes a different set of locking slots disposed at each end for receiving and lockingly engaging a corresponding one of the two sets of dogs. The discharge tube is relocatable to extend from one end of the coupling to permit engagement of the set of slots in the other end of the coupling with the set of dogs corresponding with the discharge outlet.
Claims13
A coupling for engaging either of a first waste water outlet having a first configuration of a set of dogs or a second waste water outlet having a second configuration of a set of dogs to direct waste water into a discharge hose, said coupling comprising in combination:
- a) a hollow section having opposed first and second terminal ends, said hollow section including an interior surface;
- (b) a first set of slots disposed at said first terminal end for engaging in locking engagement with said first configuration set of dogs associated with the first waste water outlet;
- (c) a second set of slots disposed at said second terminal end for engaging in locking engagement with said second configuration set of dogs associated with the second waste water outlet;
- (d) a discharge tube having an inlet end and an outlet end for directing waste water flowing into said hollow section, through said outlet end and into the discharge hose, said discharge tube including a radial first flange disposed at said inlet end positionable in juxtaposed relationship with a second flange;
- and
- (e) a retainer mechanism for retaining said inlet end of said discharge tube within said hollow section and for extending said outlet end from said hollow section, said retainer mechanism including said second flange extending inwardly radially from said interior surface.
A coupling useable with either of a first conventional water discharge outlet or a second conventional water discharge outlet that may be used with a recreational vehicle to interconnect the discharge outlet with a discharge hose, said coupling comprising in combination:
- (a) an hollow section having a first terminal end selectively engageable with one of the first and second water discharge outlets and a second terminal end selectively engageable with the other of the first and second water discharge outlets, said hollow section including an interior surface;
- (b) a discharge tube having an inlet end and an outlet end extending from said hollow section to support the discharge hose for discharging waste water flowing into said hollow section and through said outlet end into the discharge tube, said discharge tube including a radial first flange disposed at said inlet end positionable in juxtaposed relationship with a second flange;
- and
- (c) a retainer mechanism for retaining said inlet end of said discharge tube within said hollow section and for extending said outlet end of said discharge tube from said hollow section, said retainer mechanism including said second flange extending inwardly radially from said interior surface.
A method for interconnecting a discharge hose through a coupling with either of two different but conventional types of water discharge outlets that may be used with a recreational vehicle, said method comprising the steps of:
- (a) selectively lockingly engaging a terminal end of the coupling corresponding with the type of discharge outlet present at the recreational vehicle, said step of lockingly engaging including the step of mating slots disposed at a terminal end of the coupling with dogs extending from the discharge outlet;
- (b) positioning one end of a discharge tube within the coupling to permit extension of the other end of the discharge tube from the other terminal end of the coupling not in engagement with the discharge outlet;
- (c) retaining the one end of the discharge tube within the coupling;
- and
- (d) attaching the discharge hose to the other end of the discharge tube extending from the coupling.
