Abstract
A waste evacuation attachment for a recreational vehicle comprises a rigid cylindrical housing readily mountable to the existing fittings of a sewage discharge outlet of the recreational vehicle, there being a telescoping hose contained within the housing and having a fitting on the extendable end to adapt the hose to waste receiving receptacles, the assembly eliminating the difficulties inherent in conventional recreational vehicles which require the attachment and removal of a separate hose unit whenever the vehicle hooks up at an overnight site.
Claims6
A waste evacuation attachment for a recreational vehicle having a stub pipe waste outlet, said attachment comprising:
- (a) a rigid cylindrical housing having means to connect one end thereof rigidly to said stub pipe in communication therewith, whereby said housing when so connected defines an integral, immobile extension of said stub pipe;
- (b) an axially expandable hose mounted in said housing and having a fixed end connected to said one end of said housing and having a free end extendable externally of said housing;
- (c) Said hose being of length when expanded which is large compared to the length of said housing to permit the free end of said hose to reach a stationary sewage receiving tank, and the compressed length of said hose being such that said hose is completely contained in said housing when compressed;
- (d) an end piece element mounted on the free end of said hose and being adapted to connect to the inlet of a stationary sewage receiving tank to define a continuous waste flow passageway from said waste containment facility through said housing and hose into said stationary sewage receiving tank;
- (e) a cap element and means to mount same in sealed relation to said end piece element when said attachment is not in use;
- and
- (f) said and piece element having means to engage same to said housing when the attachment is not in use to define a compact, self-contained sealed unit completely containing said hose.
In a recreational vehicle having a waste containment facility, a self-contained waste discharge system for delivering waste to a stationary sewage receiving tank comprising:
- (a) a rigid housing mounted on said vehicle and having one end thereof communicating with said discharge system and the other end being open;
- (b) an axially expandable hose having a fixed end mounted internally in said housing and having a free end extendable externally of said housing through the open end thereof;
- (c) said hose being of length when expanded which is large compared to the length of said housing to permit the free end of said hose to reach a stationary sewage receiving tank, and the compressed length of said hose being such that said hose is completely contained in said housing when compressed;
- (d) an end piece element mounted on the free end of said hose and being adapted to connect to the inlet of a stationary sewage receiving tank to define a continuous waste flow passageway from said waste containment facility through said housing and hose into said stationary sewage receiving tank;
- (e) a cap element and means to mount same in sealed relation to said end piece element when said waste discharge system is not in use;
- and
- (f) said and piece element having means to mount same to the free end of said housing to completely contain said hose and define a self-contained, sealed unit.
