Oil filter removal tool and method of use

Abstract

An oil filter removal tool with a cavity for receiving the oil filter, a tapered base portion with reverse (e.g. left handed) threads for gripping the base of the oil filter, and a lip for capturing spilled oil. A wrench connection below the base portion of the tool fits a typical socket wrench head to allow for easy removal of the oil filter using a common tool. The reverse threads grip the base of the oil filter when being turned to the left, and as they tighten onto the filter, they grip tighter and tighter and then begin to loosen the filter. As the filter comes loose, any spilt oil will be captured within the cavity of the removal tool.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to an oil filter removal tool and method for use thereof, and more specifically to an oil filter removal tool with reverse threads and wrench connection.

2. Description of the Related Art

Anyone who has removed, or tried to remove, an oil filter from their vehicle has no doubt run into some complication, whether it is difficulty in grasping and removing the filter itself, or dealing with spilt oil upon beginning to loosen and removing the filter. While some tools exist to help deal with this issue, such as oil filter removal wrenches, these tools cannot fit or be easily used in tight locations and do not help to deal with the spilt oil.

Heretofore there has not been available a system or method for an oil filter removal tool with the advantages and features of the present invention.

BRIEF SUMMARY OF THE INVENTION

The present invention generally provides an oil filter removal tool with a cavity for receiving the oil filter, a tapered base portion with reverse (e.g. left handed) threads for gripping the base of the oil filter, and a lip for capturing spilled oil. A wrench connection below the base portion of the tool fits a typical socket wrench head to allow for easy removal of the oil filter using a common tool. The reverse threads grip the base of the oil filter when being turned to the left, and as they tighten onto the filter, they grip tighter and tighter and then begin to loosen the filter. As the filter comes loose, any spilt oil will be captured within the cavity of the removal tool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

I. Introduction and Environment

As required, detailed aspects of the present invention are disclosed herein, however, it is to be understood that the disclosed aspects are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art how to variously employ the present invention in virtually any appropriately detailed structure.

Certain terminology will be used in the following description for convenience in reference only and will not be limiting. For example, up, down, front, back, right and left refer to the invention as orientated in the view being referred to. The words, “inwardly” and “outwardly” refer to directions toward and away from, respectively, the geometric center of the aspect being described and designated parts thereof. Forwardly and rearwardly are generally in reference to the direction of travel, if appropriate. Said terminology will include the words specifically mentioned, derivatives thereof and words of similar meaning.

II. Preferred Embodiment Oil Filter Removal Tool System 2

As shown in the figures, the present invention provides an oil filter removal tool system 2 including a tool 6 for removing an oil filter 4 from a vehicle. The tool 6 includes an internal cavity 10 for receiving the filter 4 when removing it, and also includes a lip 8 for capturing oil from the vehicle as the filter 4 is being removed. The oil can be captured within the cavity 10. A wrench connection 12 at the bottom of the tool allows for the user to connect a common socket wrench 24 to the socket receiver 14 to make it easy to remove the tool. The socket receiver is a simple square receptacle for receiving a standard socket wrench.

FIG. 2 shows the reverse (e.g. left handed) threads 16 within the tapered base portion 20 of the tool. As the tool 6 is placed over the filter 4, as shown in FIG. 3, the reverse threads 16 grip the base portion 22 of the filter. Typically this base portion 22 of the filter is covered with a rubberized material to help with hand-gripping the filter when loosening or tightening, however the present invention will work with an oil filter having a base portion 22 made of any suitable material. The reverse threads 16 will grip to any material however, and as the tool 6 is turned left to loosen the filter 4, the threads will get tighter and tighter onto the base 22 of the filter 4.

The tapered base portion 20 of the tool 6 allows the tool to accommodate an oil filter 4 of virtually any typical diameter. This allows a single one-sized tool 6 to be used to remove most currently used engine oil filters 4, which generally range from 2.9 inches in diameter to 4.2 inches in diameter. The threads 16 inside of the tapered base portion 20 will grip the base portion 22 of the filter 4 no matter how large or small the filter's diameter. This means the user only needs the single tool 6 and a wrench 24 to remove any filters 4 that they may need to remove.

As the filter is loosened, the oil from the vehicle will spill over the sides of the filter and be captured by the lip 8 of the tool 6, and stored within the cavity 10 of the upper portion 18 of the tool 6.

The internal cavity 10 does not necessarily need to be able to old all oil stored within the oil pan, but is primarily designed merely to capture the oil which spills when removing the filter 4. However, it could be designed to hold more.

The tool 6 is preferably made of a single piece of material which may be cast or molded, and includes no moving parts.

It is to be understood that while certain embodiments and/or aspects of the invention have been shown and described, the invention is not limited thereto and encompasses various other embodiments and aspects.
