Oil drainage apparatus for a lawn mower

An oil drainage apparatus for a lawn mower including a tapered semi-cylindrical upper funnel having a semicircular top surface and a semicircular bottom surface. A semicircular bottom edge of a semi-cylindrical lip is attached to the top surface of the upper funnel. A semicircular top area of a semi-cylindrical middle funnel is attached to the bottom surface of the upper funnel. A semicircular top end of a tapered semi-cylindrical lower funnel is attached to the bottom area of the middle funnel. A substantially U-shaped channel is continuously disposed from the lip to the lower funnel. A crimp protrusion is medially disposed on the lip. A screen is disposed within the interior cavity between the bottom surface of the upper funnel and the top area of the middle funnel. The lip removably extends around a lower portion of a lawn mower oil drain plug.

BACKGROUND OF THE INVENTION

Various types of oil drainage apparatuses are known in the prior art. However, what has been needed is an oil drainage apparatus for a lawn mower including a tapered semi-cylindrical upper funnel having a semicircular top surface and a semicircular bottom surface, a semicircular bottom edge of a semi-cylindrical lip attached to the top surface of the upper funnel, a semicircular top area of a semi-cylindrical middle funnel attached to the bottom surface of the upper funnel, and a semicircular top end of a tapered semi-cylindrical lower funnel attached to the bottom area of the middle funnel. What has been further needed is a substantially U-shaped channel continuously disposed from the lip to the lower funnel, a crimp protrusion medially disposed on the lip, and a screen disposed within the interior cavity between the bottom surface of the upper funnel and the top area of the middle funnel. Lastly, what has been needed is for the lip to removably extend around a lower portion of a lawn mower oil drain plug and for the lower funnel to be disposed within an oil collection pan. The oil drainage apparatus for a lawn mower thus provides a user with a quick and easy way in which to drain used oil from a mower and protects the environment by eliminating the need for the user to drain the oil onto an outdoor surface.

FIELD OF THE INVENTION

The present invention relates to oil drainage apparatuses, and more particularly, to an oil drainage apparatus for a lawn mower.

SUMMARY OF THE INVENTION

The general purpose of the present oil drainage apparatus for a lawn mower, described subsequently in greater detail, is to provide an oil drainage apparatus for a lawn mower which has many novel features that result in an oil drainage apparatus for a lawn mower which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.

To accomplish this, the present oil drainage apparatus for a lawn mower includes a tapered semi-cylindrical upper funnel having a semicircular top surface and a semicircular bottom surface. A semi-cylindrical lip has a semicircular top edge and a semicircular bottom edge attached to the top surface of the upper funnel. A diameter of the top surface of the upper funnel is equal to a diameter of the lip, and the diameter of the top surface of the upper funnel is less than a diameter of the bottom surface of the upper funnel. A semi-cylindrical middle funnel has a semicircular bottom area and a semicircular top area attached to the bottom surface of the upper funnel. The diameter of the bottom surface of the upper funnel is equal to a diameter of the middle funnel. A tapered semi-cylindrical lower funnel has a semicircular bottom end and a semicircular top end attached to the bottom area of the middle funnel. A diameter of the top end of the lower funnel is equal to the diameter of the middle funnel, and the diameter of the top end of the lower funnel is greater than a diameter of the bottom end of the lower funnel. Each of the lip, the upper funnel, the middle funnel, and the lower funnel is optionally plastic for better durability and transportability.

The oil drainage apparatus for a lawn mower further includes a substantially U-shaped channel, a substantially circular downwardly extended crimp protrusion, and a semicircular screen. The channel is continuously disposed from the top edge of the lip to the bottom end of the lower funnel, the crimp protrusion is medially disposed on the lip, and the screen is disposed within the channel between the bottom surface of the upper funnel and the top area of the middle funnel. The lip removably extends around a lower portion of a lawn mower oil drain plug. Furthermore, the lower funnel is disposed within an oil collection pan and the middle funnel is downwardly extended from the upper funnel when the lip is extended around the lower portion of the lawn mower oil drain plug. As a result, oil is configured to drain from the lawn mower oil drain plug through the channel and into the oil collection pan when the lip is extended around the lower portion of the lawn mower oil drain plug. A combined length of the lip, the upper funnel, the middle funnel, and the lower funnel is in a range of approximately 14 inches to 15 inches in order to adequately allow the drainage of oil through the channel.

DETAILED DESCRIPTION OF THE DRAWINGS

With reference now to the drawings, and in particularFIGS. 1 through 5thereof, an example of the instant oil drainage apparatus for a lawn mower employing the principles and concepts of the present oil drainage apparatus for a lawn mower and generally designated by the reference number10will be described.

Referring toFIGS. 1 through 5the present oil drainage apparatus for a lawn mower10is illustrated. The oil drainage apparatus for a lawn mower10includes a tapered semi-cylindrical upper funnel20having a semicircular top surface22and a semicircular bottom surface24. A semi-cylindrical lip26has a semicircular top edge28and a semicircular bottom edge30attached to the top surface22of the upper funnel20. A diameter of the top surface22of the upper funnel20is equal to a diameter of the lip26, and the diameter of the top surface22of the upper funnel20is less than a diameter of the bottom surface24of the upper funnel20. A semi-cylindrical middle funnel32has a semicircular bottom area34and a semicircular top area36attached to the bottom surface24of the upper funnel20. The diameter of the bottom surface24of the upper funnel20is equal to a diameter of the middle funnel32. A tapered semi-cylindrical lower funnel38has a semicircular bottom end40and a semicircular top end42attached to the bottom area34of the middle funnel32. A diameter of the top end42of the lower funnel38is equal to the diameter of the middle funnel32, and the diameter of the top end42of the lower funnel38is greater than a diameter of the bottom end40of the lower funnel38. Each of the lip26, the upper funnel20, the middle funnel32, and the lower funnel38is optionally plastic.

The oil drainage apparatus for a lawn mower10further includes a substantially U-shaped channel44, a substantially circular downwardly extended crimp protrusion46, and a semicircular screen48. The channel44is continuously disposed from the top edge28of the lip26to the bottom end40of the lower funnel38, the crimp protrusion46is medially disposed on the lip26, and the screen48is disposed within the channel44between the bottom surface24of the upper funnel20and the top area36of the middle funnel32. The lip26removably extends around a lower portion50of a lawn mower oil drain plug52. Furthermore, the lower funnel38is disposed within an oil collection pan54and the middle funnel32is downwardly extended from the upper funnel20when the lip26is extended around the lower portion50of the lawn mower oil drain plug52. As a result, oil is configured to drain from the lawn mower oil drain plug52through the channel44and into the oil collection pan54when the lip26is extended around the lower portion50of the lawn mower oil drain plug52. A combined length of the lip26, the upper funnel20, the middle funnel32, and the lower funnel38is in a range of approximately 14 inches to 15 inches.
