The present invention relates to recreational vehicles (RVs) and, more particularly, a manually operated, nonpowered waste disposal system for disposal of waste from a RV, wherein the waste disposal system has a proximal end connected to the sewer outlet of a sanitation unit of the RV, and wherein the distal end of the waste disposal system is rotatable relative to and selectively extendable from the proximal end.
RVs are synonymous with freedom, a mobile house that can roam the open roads, allowing users to explore remote parts of the country. The process of waste disposal (both sewage and gray water) that is required during this exploration is, however, laborious as it currently demands handling and assembling of various, disparate equipment and hardware as well as their disassembly and storage when travelling. The current process of connecting and operating a RV sewer hose is time-consuming and requires manual removal, assembly, and connection before each use. It also demands, subsequent use, disconnection, disassembly and storage after each use. The current capability to store RV sewer hoses is a separate process that is inconvenient, cumbersome as well as requiring storage space and valuable time to setup before use and breakdown and storage after use.
As can be seen, there is a need for a manually operated, nonpowered waste disposal system for disposal of waste from a RV to eliminate the current need to perform the cumbersome and time-consuming steps of removing, assembling, connecting, and restoring a sewage drain hose for RVs. The present invention embodies a multi-purpose and systemic device that attaches to an RV's sewage disposal outlet and engages the RV's sewage drain hose, thereby enabling its rotation and selective linear positioning and repositioning during use and thereafter. By way of the systemic device, the RV's sewage drain hose can maintain a constant stored position and be selectively expandable for its positioning and repositioning during and after use, without having to disconnect or reconnect the sewage drain hose to and from the RV, or even directly handle the flexible sewage drain hose, that can be unwieldy.
As a result, the present invention simplifies the RV waste tank drainage process through installing an efficient, nonpowered connection and rotational conduit system that safely stores the flexible sewage drain hose(s) during nonuse and transport, and thereby eliminates the laborious need to disconnect and store the hose after each use.
In one aspect of the present invention, a waste disposal system for a recreation vehicle with an external sewage outlet includes: a conduit assembly extending from an upstream portion and a downstream portion; the upstream and downstream portions define a bearing connection, wherein the downstream portion is rotatable relative the upstream portion; and the downstream portion defines a telescopic arrangement of a plurality of conduits, wherein the telescopic arrangement is movable between an extended position and a nest position.
In another aspect of the present invention, the waste disposal system includes upstream portion having a proximal end connected to the RV's external sewage outlet, wherein the proximal end connector has an access opening operatively associated with a clamp bridging at the proximal-most end of the access opening to provide a secure connection as well as access to the waste hose connection point. The bearing connection comprises two interfacing flange portions, each flange portion having a radial connection slot and one or more flange holes radially spaced apart thereto, wherein the radial connection slot concentrically aligns with the one or more flange holes of the interfacing flange portion. Each of the plurality of conduits have a linear connection slot and a conduit hole equally spaced apart.
In yet another aspect of the present invention, a waste disposal system for a recreation vehicle with an external sewage outlet provides the following: a conduit assembly extending from an upstream portion and a downstream portion; the upstream and downstream portions define a bearing connection enabling the downstream portion to be rotatable relative the upstream portion; the downstream portion is movable between an extended position and a contracted position; and the downstream portion defines an extension arrangement of a plurality of threaded conduit sections configured to store two waste hoses in the extended condition. These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
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.
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.
Referring now to
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
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.
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.
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.
