  • Patent number: 5971438
    Abstract: 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.

  • Patent number: 5897083
    Abstract: A retainer (10) for holding and protecting a sewer hose for a recreational vehicle is provided. The retainer (10) has an elongate hollow tubular body portion (20) with a flat base (40) attached to a bottom end (23) of the body portion (20). A cap (50) is removably attachable to a top end (22) of the body portion (20). Drain holes (34) provide for ventilation between a hollow interior region (36) of the body (20) and the environment surrounding the retainer (10). Bores (48), (58) pass through the base (40) and the cap (50) to allow for thorough ventilation of the hollow interior region (36) of the body portion (20). The body portion (20) is provided with a width which is less than a width of the sewer hose (H). The base (40) and removable cap (50) are provided with a width which is greater than a width of the sewer hose (H). Hence, the sewer hose (H), when it is located upon the body portion (20) of the retainer (10), is prevented from falling off of the body portion (20).
