DETAILED DESCRIPTION OF THE INVENTION

[0020] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0021] Broadly, an embodiment of the present invention provides a recreational vehicle (RV) waste disposal system, wherein the waste disposal system has a proximal end connected to the sewer outlet of the RV's sanitation unit, and wherein the distal end of the waste disposal system is rotatable relative to and extendable from the proximal end.

[0022] Referring now to FIGS. 1 through 3, the present invention may include a waste disposal system 10. The waste disposal system 10 may be designed for a sanitation system 10A having an external sewer connection 10B or sewage outlet connectable with a sewage conduit 10C. The sanitation system 10A may be associated with a stationary or mobile structure, such as a recreational vehicle.

[0023] The disposal system 10 may include a partial open holder 12A. The partial open holder 12A may have a conduit portion 121 that extends from a proximal end 123 to a distal end 125. The proximal end 123 may include a partial flange 133. An access opening 12C may be formed in the conduit portion 121, wherein the access opening 12C communicates to the proximal end 123, defining the bounds of the partial flange 133. Accordingly, the access opening 12C allows for access to the sewer connection 10B through the conduit portion 121. A holder clamp 12B may be dimensioned to interconnect the opposing bounds of the partial flange 133, as illustrated in FIG. 3, and thereby fasten to the sewer connection 10B when fasteners 14 connect ends of the holder clamp 12B to complementary ends of the partial flange 133.

[0024] In certain embodiments, a first bearing ring 18 having an upper cylindrical portion slides into the distal end 125, wherein the first bearing ring 18 provides a first flange portion with a first radial connection slot 18A and connection holes 18B radially spaced apart between opposing ends of the first radial connection slot 18A.

[0025] A second bearing ring 20 having a second cylindrical portion that extends away from the distal end 125, wherein the second bearing ring 20 provides a second flange portion with a second radial connection slot 20A and holes 20B radially spaced apart between opposing ends of the second radial connection slot 20A.

[0026] The first and second flanges portions abut and are connected through their respective radial connection slots 18A and 20A by way of pins 22A and complementary connectors 22B. A cap 16 may be dimensioned and adapted to collar the distal end 125 while shielding the first and second flanges portions.

[0027] Referring to FIGS. 4 through 5B, a downstream conduit 24 may slide its proximal end into or over the second cylindrical portion. The downstream conduit 24 may have a handle 24A that is pivotable about a pivot point 12C. The downstream conduit 24 may be one or various conduit types and associated fittings, including but not limited to an elbow section.

[0028] The bearing point defined by the interfacing first and second flanges portions allowing for rotation of the downstream conduit 24 without movement to the holder 12A, through the pins 22A riding along the respective radial connection slots 18A and 20A, as illustrated in FIGS. 5A and 5B. As a result, the downstream conduit 24 rotates about a longitudinal axis of the holder 12A.

[0029] Referring to FIGS. 6 through 7, one or more linear conduits 26, 28, 30, each providing a linear connection slot 26B, 28B, 30B, respectively, spaced apart from a respective connection hole 26A, 28A, 30A. The connection slot of one conduit may engage the connection hole of an adjacent conduit by way of a guide pin 32. As a result, the present invention enables selective interconnectivity between the two adjacent, operatively associated conduits, whereby the length that one conduit protruded from its operatively associated adjacent conduit can be selected by the user. Thereby, facilitating moving the disposal system 10 between the extended position (FIG. 6) or a storage position (FIG. 8). As a result, the linear conduits 26, 28, 30 can be sequentially connected and be in either the extended position or the storage position, whichever suits the user. Conceptually, this selectivity enables a telescopic or collapsible functionality between the one or more linear conduits 26, 28, 30.

[0030] Alternatively, the one or more linear conduits 26, 28, 30 may have complementary threading 50 (e.g., male and female), as illustrated in FIG. 7, for interconnecting adjacent conduits.

[0031] Referring to FIGS. 8 through 9, the linear conduit 30 may have an access opening 12C to enable access to the sewage conduit 10C extending from the sewer connection 10B to the distal-most linear conduit 30. The access opening 12C may communicate to the distal end 42. A collar portion 44 may bridge the bounds of the distal end 42 defined by the access opening 12C, as illustrated in FIG. 9. Connectors 46 may facilitate a removable connection between the collar portion 44 and the distal end 42. In certain embodiments, other fittings 40A may be used to define the path of the sewage conduit 10C, as illustrated in FIG. 8.

[0032] Referring to FIG. 10, in other embodiments the lower conduit 24 connects directly to the sanitation compartment floor 10D of the sanitation system 10A.

[0033] A method installing the waste disposal system 10 disclosed above may include the following. The holder clamp 12B facilitates joining the holder 12A to the to the main sewer connection 10B outlet, wherein the holder 12A has a partial access opening 12C to allow access to the sewer connection 10B and sewage conduit 10A. Bearing assisted connectors 18 and 20 may interconnect an upstream conduit and the downstream conduit 24, allowing for independent movement of the downstream conduit 24. The handle 24A may be attached thereto allowing for easy rotation of the downstream conduit 24. A linear connection slot with a stopping pin may be manufactured at the end of the downstream conduit 24. A plurality of conduit sections 26, 28, and 30 may each have a similar linear connection slot (“lips”) and stopper. The distal-most collapsible conduit 30 has an access opening 12C to a handle the sewage conduit 10A.

[0034] The waste disposal system 10 connects directly to the RV's sewer outlet with an easy-to-use handle for rotating of the storage device from an in-use position to a stored position under the recreational vehicle when traveling, where a user can set the appropriate stops for the storage/travel position and the extended/operational positions. Then the user connects the sewer hose to the sanitation unit and places the hose within the device, however it is configured. When needing to dump the waste, the handle allows the user to rotate and extend the hose to the correct distance for the dumping of waste. When complete, the user may rotate the device and store it back under the vehicle for travel.
