DETAILED DESCRIPTION OF THE INVENTION
With reference now to the drawings, and in particular to FIGS. 1 through 3 thereof, a new Recreational Vehicle holding tank disposal system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 3, the Recreational Vehicle holding tank disposal system 10 may generally comprise a duct assembly 11 including a rigid first pipe 12 with inlet and outlet ends 15, 16 and a bore 17 extending therethrough, a rigid second pipe 18 with an open first end 20, a second end 21, and a bore 22 extending therethrough with the second pipe 18 in operable communication with the first pipe 12, and a flexible hose 28 with open first and second ends 29, 30 and a bore 31 extending therethrough with the flexible hose 28 conventionally fastened with a hose clamp at the inlet end 15 of the first pipe 12, and may also comprise a holding tank connector assembly 62 conventionally connected to the duct assembly 11 and adapted to be removably connected to a sewage holding tank 63, and may further comprise a sewer adapter 52 attachable to the duct assembly 11 and adapted to be removably disposed in a sewer inlet.
As illustrated in FIG. 1, the first pipe 12 may have a perimetrical dimension smaller than that of the second pipe 18 with the first pipe 12 slidably disposed in and telescopingly extendable from the second pipe 18. The first pipe may be slidably disposed through the open first end 20 of the second pipe 18 with the inlet end 15 of the first pipe 12 exposed outside of the second pipe 18. The duct assembly 11 may also include an annular seal 27 conventionally adhered with adhesive to an inner side 64 of a side wall 19 of the second pipe 18 and engagable to an outer side 14 of a side wall 13 of the first pipe 12 to prevent sewage leakage between the first and second pipes 12, 18. The annular seal 27 may be disposed at the first end 20 of the second pipe 18 and may extend a selected distance along and inside the bore 22 of the second pipe 18. The annular seal 27 may be made of rubber silicone. The duct assembly 11 may also have a tubular end portion 23 conventionally disposed at the second end 21 of the second pipe 18 with an opening 24 disposed through a side wall 65 of the tubular end portion 23. The duct assembly 11 may also include a drainage spout 25 conventionally attached to and extending from the tubular end portion 23 and disposed about the opening 24 with the drainage spout 25 having external threads 26 and a longitudinal axis extending perpendicular to a longitudinal axis of the bore 22 through the second pipe 18. The duct assembly 11 may further include a spout member 68 conventionally attached to and extending through an end wall 69 of the tubular end portion 23 with a cap member 70 removably and conventionally attached about the spout member 68 with the spout member 68 adapted to be connected to a garden hose for cleaning out the duct assembly 11.
As shown in FIGS. 1-3, the hose 28 may have a concertinaed side wall 32 for flexibility to connect to the sewage holding tank 63. The duct assembly 11 may further include an end cap 58 removably and conventionally attached to the drainage spout 25 over the opening 24, and also includes a tether 59 having one end 60 conventionally attached to the end cap 58 and another end 61 conventionally attached to the tubular end portion 23 to prevent loss of the end cap 58 when removed from the drainage spout 25.
As illustrated in FIGS. 1-3, the holding tank connector assembly 62 may include a rigid collar 33 conventionally and securely attached at and about the first end 29 of the hose 28, and may also include posts 35, 36 spacedly and conventionally attached and welded to an outer side 34 of the collar 33 and extending outwardly therefrom and adapted to removably connect to the sewage holding tank 63. The holding tank connector assembly 62 may further include fastening members 37, 38 pivotally and conventionally attached to the outer side 34 of the collar 33 with each of the fastening members 37, 38 having a hook 39, 40 at a distal end 41, 42 thereof.
As shown in FIGS. 1-3, the Recreational Vehicle holding tank disposal system 10 may further include a cap assembly 43 removably attached to the collar 33 and including a main cap 66 having an end wall 44 and a side wall 45 depending from a perimeter of the end wall 44. The main cap 66 may have post members 46, 47 conventionally attached to an outer side 67 of the side wall 45 and extending outwardly therefrom and removably engaged to the hooks 39, 40 of the fastening members 37, 38 to removably retain the main cap 66 over and close the first end 29 of the hose 28. The main cap 66 may also have a hole 48 disposed through the end wall 44 with an inlet spout 49 conventionally disposed about the hole 48 and extending outwardly from the end wall 44 with the inlet spout 49 having external threads 50 for connecting to a garden hose to rinse and clean the sewage out of the duct assembly 11. The cap assembly 43 may further include a secondary cap 51 threadable upon the inlet spout 49 to close the hole 48 through the main cap 66.
As illustrated in FIGS. 1-3, the sewer adapter 52 may be a funnel having an upper portion 53 and a lower portion 57 with the upper portion 53 tapered inwardly and downwardly towards the lower portion 57 and having threads 56 on the inner side 55 of a side wall 54 of the upper portion 53. The funnel 52 is removably threaded to the drainage spout 25 with the lower portion 57 adapted to extend into the sewer inlet to drain the sewage from the sewage holding tank 63.
In use, the user could remove the main cap 66 from the collar 33 by unfastening the hooks 39, 40 from the post members 46, 47 on the main cap 66 and then secure the collar 33 to the sewage holding tank 63 using the posts 35, 36 on the collar 33 and remove the end cap 58 from the drainage spout 25 and attach the funnel 52 to the drainage spout 25 and insert the funnel 52 into the sewer inlet and open the sewage holding tank 63 to allow the sewage to drain from the sewage holding tank 63 through the duct assembly 11 and into the sewer inlet. Once the sewage holding tank 63 is completely drained, the user could disconnect the collar 33 from the sewage holding tank 63 and reattach the main cap 66 to the collar 33 and also then remove the secondary cap 51 and attach a garden hose to the inlet spout 49 and turn on a water source connected to the garden hose to rinse and clean the duct assembly 11. In the alternative, the user could attach the end cap 58 to the drainage spout 25 and not attach the main cap 66 to the collar 33 and remove the cap member 70 from the spout member 68 and attach the garden hose to the spout member 68 and run water through and clean out the duct assembly 11.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the RV holding tank disposal system. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
