发明名称 Mobile vehicle sewage removal system
摘要 A sewage removal system 10 is provided for quickly, securely and sanitarily connecting the onboard holding tank H of a typical recreational vehicle or travel trailer to an in-ground stationary waste disposal site S. The system 10 includes two hoses 20, 21 which may be coupled via a union 50 to provide hoses 20, 21 of greater combined length to reach the site S when located too far for a single hose 20, 21. The hoses 20, 21 include quick connect couplings 30 secured to each end 22. Locking hooks 40 extend from the annular rims 39 of the couplings 30 to provide a means for securely engaging protrusions 56, 66 to create a sealed joint. The system 10 includes two elbow adapters 60 to allow simple connection to an inlet tube T of the stationary waste disposal site S. The first elbow adapter 60 includes a male threaded connector 70 for coupling with a female threaded fitting F of the inlet tube T. A second elbow adapter 60 includes a female threaded connector 80 for connection to a male threaded fitting M of the inlet tube T.
