DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved drain P-trap, embodying the principles and concepts of the present invention and generally designated by the reference numeral 10, will be described.

(9) The present invention, the drain P-trap 10 is comprised of a plurality of components. Such components in their broadest context include an inflow pipe, an intermediate pipe, an outflow pipe, and a baffle. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

(10) A drain P-trap 10, comprising several components, in combination is herein described.

(11) There is first provided an inflow pipe 12. The inflow pipe has a first internal diameter. The inflow pipe has a round configuration 14. The inflow pipe has a continuous circumferential wall 16, with a rearward portion 18 and a forward portion 20. The rearward portion of the inflow pipe has an upper extent 22 and a lower extent 24. The forward portion of the inflow pipe has an upper extent 26 and a lower extent 28.

(12) The upper extent of the rearward portion of the inflow pipe and the upper extent of the forward portion of the inflow pipe are continuous, thereby forming a round opening 30 of the inflow pipe. The inflow pipe has an internal surface 32 and an external surface 34 with a width there between.

(13) There is next an intermediate pipe 40. The intermediate pipe has a lower surface 42. The intermediate pipe lower surface has a curved rearward portion 44 and a curved forward portion 46. The curved rearward portion of the lower surface of the intermediate pipe is continuous with the lower extent of the rearward portion of the inflow pipe.

(14) The intermediate pipe has an internal surface 48 which is continuous with the internal surface of the inflow pipe. The intermediate pipe has an external surface 50 which is continuous with the external surface of the inflow pipe.

(15) The intermediate pipe has the width between the internal surface of the intermediate pipe and the external surface of the intermediate pipe. The intermediate pipe internal surface of the lower surface has a first radius of curvature 52.

(16) There is an outflow pipe 60. The outflow pipe has the first diameter. The outflow pipe has a round configuration. The outflow pipe has a continuous circumferential wall 62, with an upper portion 64 and a lower portion 66.

(17) The upper portion of the outflow pipe has a forward extent 68 and a rearward extent 70. The lower portion of the outflow pipe has a forward extent 72 and a rearward extent 74. The forward extent of the upper portion of the outflow pipe and the forward extent of the lower portion of the inflow pipe are continuous with each other, thereby forming a round opening 76 of the outflow pipe.

(18) The upper portion of the outflow pipe and the lower portion of the outflow pipe have an internal surface 78 and an external surface 80, with the width there between.

(19) The radius of curvature of the internal surface of the intermediate pipe runs from the internal surface of the lower extent of the rearward portion of the inflow pipe to the internal surface of the rearward portion of the lower portion of the outflow pipe. The radius of curvature of the internal surface of the intermediate pipe comprises a first distance.

(20) Lastly, there is a baffle 90. The baffle has an upper extent 92 and a lower extent. The baffle has an inflow surface 94 and an outflow surface 96, with the width there between.

(21) The upper extent of the baffle is located at the internal surface of the rearward portion of the upper portion of the outflow pipe. The lower extent of the baffle has a linear configuration.

(22) The lower extent of the baffle is located at a second distance from the internal surface of the lower portion of the intermediate pipe. The second distance of the lower extent of the baffle to the internal surface of the lower portion of the intermediate pipe is less than the first distance of the radius of curvature of the intermediate pipe.

(23) The herein described drain P-trap differs from the well known myriad of drain P-traps which exist in the marketplace. The baffle is the key to the different function of the herein described device.

(24) The P-trap has a lower top to bottom profile, which is possible because of the baffle inside of the internal passageway. The lower extent of the baffle is located in alignment with the internal surface of the lower portion of the outflow. The distance from the lower extent of the baffle to the internal surface of the intermediate pipe is less than the diameter of the opening of the inflow pipe and the outflow pipe.

(25) The lessening of distance between the lower extent of the baffle and the internal surface of the intermediate pipe, which is less than the diameter of the inflow pipe and the outflow pipe, causes an increase in the rate of flow through the passageway between the baffle and the lower internal surface of the intermediate pipe. The reduced distance between the baffle lower extent and the intermediate pipe internal wall effectively causes a reduction in pipe diameter. Even slow flowing liquid increases in relative velocity as it moves through the smaller opening, thereby causing a flushing action of the intermediate pipe. The flushing action, caused by the reduction in effective pipe diameter, causes a cleaning of the P-trap of any debris and algae buildup.

(26) As to 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.

(27) 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.

(28) Therefore, the foregoing is considered as illustrative only of the principles of the invention. 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.
