Abstract

An oil filter wrench for use in tightening or loosening an oil filter includes a band assembly configured to be placed over the oil filter; a handle assembly attached to the band assembly for use in tightening and turning the band assembly; and a layer of flexible or compressible high friction material applied over a portion of the band assembly to reduce slippage between the band assembly and the oil filter.

Claims (21)

1. An oil filter wrench for tightening or loosening an oil filter, the oil filter wrench comprising:

a band assembly configured to be placed over the oil filter, the band assembly having an inner band surface, an outer band surface, and side edges between the inner band surface and the outer band surface;

a handle assembly attached to the band assembly for tightening and turning the band assembly to tighten or loosen the oil filter; and

a layer of high friction material applied over a majority of the inner band surface, wherein the layer includes a plurality of raised strips that extend parallel to a longitudinal axis of the band assembly and across substantially all of a length of the inner band surface to reduce slippage between the inner band surface and the oil filter,

wherein the plurality of strips covers at least 25% of the inner band surface and the high friction material is applied to the band assembly in a dipping process or in a powder coating process.

2. An oil filter wrench for tightening or loosening an oil filter, the oil filter wrench comprising:

a band assembly configured to be placed over the oil filter, the band assembly having an inner band surface, an outer band surface, and side edges between the inner band surface and the outer band surface;

a handle assembly attached to the band assembly for tightening and turning the band assembly to tighten or loosen the oil filter; and

a series of holes located on the band for securing a high friction material to the band, the high friction material being inserted into the holes via projections on the material to reduce slippage between the inner band surface and the oil filter.

3. The oil filter wrench as set forth in claim 2 , wherein the high friction material covers approximately 50% of the inner band surface.

4. The oil filter wrench as set forth in claim 2 , wherein the high friction material covers approximately 25% of the inner band surface.

5. The oil filter wrench as set for in claim 2 , wherein the series of holes includes 2-8 holes.

6. The oil filter wrench as set forth in claim 2 , wherein the high friction material is PVC material that is approximately 0.030″ thick.

7. The oil filter wrench as set forth in claim 2 , wherein the high friction material is applied to the band assembly in a dipping process, injection or compression molding process, or a powder coating process, or by mechanical or adhesive attachment.

8. The oil filter wrench as set forth in claim 2 , wherein the holes are aligned in a pattern substantially parallel to a longitudinal axis of the oil filter wrench.

9. The oil filter wrench as set forth in claim 2 , wherein the holes are aligned in a pattern substantially perpendicular to a longitudinal axis of the oil filter wrench.

10. An oil filter wrench for tightening or loosening an oil filter, the oil filter wrench comprising:

a band assembly configured to be placed over the oil filter, the band assembly having an inner band surface, an outer band surface, and side edges between the inner band surface and the outer band surface;

a handle assembly attached to the band assembly for turning the band assembly to tighten or loosen the oil filter; and

a series of holes located on the band for securing a high friction material to the band, the high friction material being inserted into the holes via projections on the material to reduce slippage between the inner band surface and the oil filter,

wherein the high friction material covers at least 25% of the inner band surface, the series of holes includes 2-8 holes, the high friction material is PVC material that is approximately 0.030″ thick, the holes are aligned in a pattern substantially parallel to a longitudinal axis of the oil filter wrench, and the high friction material is applied to the band assembly in a dipping process, mechanical or adhesive attachment, injection or compression molding process, or a powder coating process.
