Description

BACKGROUND

This disclosure pertains to blades for use with large and small oscillating and reciprocating power tools and related devices. More particularly, blade guides that improve speed and safety while providing protection against cutting blades and the like protruding outside of a desired area or beyond a specified surface depth are provided.

Oscillating power tools allow for the use of a range of attachments to saw, sand, rasp, grind, scrape, cut, and/or polish. The fitted blades include an offset that allows for cutting or accessing flush with a surface. Oscillating power tools, also called multi-tools, have a small form and the blades can be mounted in virtually any orientation allowing for cutting in areas that were often previously unreachable. Complex and precise cuts can be made without the need for removing the work piece from where it is located. The productivity increase is significant.

A blade or other accessory is attached to the tool by varying mechanisms that provide for oscillation or rapid rotation back and forth. The back and forth motion creates rapid cutting motions utilizing the blade attachments. Since the angle of oscillation is narrow there is no kick as with rotating tools, and the narrow angle provides for precise control of the multi-tool and of the action being taken.

Oscillating power tools utilize cutting blades that are standard saw blades of various type tooth configurations according to the type material to be cut. Straight blades have the teeth at the end of the blade and allow for cutting directly into the material. Bi-metal blades include smaller hardened teeth for cutting soft metals. Japan tooth blades utilize large teeth for cutting wood quickly, though they cannot cut metal. Oscillating power tools also provide for sanding and grinding operations that can be useful for cleaning as well as polishing or smoothing.

An arbor attachment is utilized for attaching a tool attachment portion to the oscillating power tool. Arbor attachments have varied widely and often utilize a proprietary arbor configuration. Universal arbor attachments have been developed to be compatible with many of these proprietary configurations.

Another type of saw is a reciprocating saw, and achieves the cutting action through a push and pull reciprocating motion of the blade. Reciprocating saws are commonly used in construction and demolition work. A reciprocating saw includes a large blade resembling a jigsaw type blade.

Oscillating power tools are useful for repairs where a cut is required in surfaces that may have electrical wires, water pipes, vents, and such like behind the surface. However, it is also very easy to cut into those wires, pipes, and the like by cutting too deep into the area being cut. What is needed is a tool that provides for cutting into a surface such as a wall, which may have wires or pipes behind, without inadvertently cutting into the respective wires, pipes, and the like.

DETAILED DESCRIPTION

Blade guides that improve both speed and safety while providing protection against cutting blades protruding outside of a desired area or beyond a specified surface depth are provided for use with large and small oscillating power tools and reciprocating power tools.

Oscillating power tools allow for the use of a range of attachments to saw, sand, rasp, grind, scrape, cut, and/or polish. The fitted blades include an offset that allows for cutting or accessing flush with a surface, or for accessing other difficult to reach locations. Oscillating power tools, also called multi-tools, have a small form and the blades can be mounted in virtually any orientation allowing for cutting in areas that were often previously unreachable. Complex and precise cuts can be made without the need for removing the work piece from where it is located. The resulting increase in productivity and efficiency is significant.

A blade or other accessory is attached to the tool by varying mechanisms that provide for oscillation or rapid rotation back and forth. The back and forth motion creates rapid cutting motions with blade attachments. Since the angle of oscillation is narrow there is no kick as with rotating tools, and the narrow angle provides for precise control of the action taken utilizing the multi-tool.

Oscillating power tools utilize cutting blades that are standard saw blades of various type tooth configurations according to the type material to be cut. Straight blades have the teeth at the end of the blade and allow for cutting directly into the material. Bi-metal blades include smaller hardened teeth for cutting soft metals. Japan tooth blades utilize large teeth for cutting wood quickly, though they cannot cut metal.

Oscillating power tools are handy tools that provide a vast improvement over previous methods of cutting in those situations where specialized cuts are necessary. However, as with any power tool, the oscillating power tool, or multi-tool, is not always an easy tool to steer or control. The guide blades disclosed herein provide for improved steering and control of various type blades that are used with multi-tool type devices.

At least some of the guide blades disclosed herein provide for similar improvements, with slight modifications, for other type power tools such as reciprocating power tools.

Reciprocating power tools perform the cutting action via a push and pull reciprocating motion of the blade. Reciprocating saws are commonly used in construction and demolition work. A reciprocating saw includes a large blade resembling a jigsaw type blade.

It should be noted that many variations in blade types may be used with both oscillating and/or reciprocating saws. Variations in blade type may include a saw tooth type cutting edge, a blade type cutting edge, or a combination of both types. In accordance with the disclosure below, the particular type cutting edge utilized is dependent on the material that the blade is intended to cut. It is within the scope of this disclosure to utilize any type blade and/or blade material in accordance with the particular target cutting material intended.

FIG. 1-A, FIG. 1-B, and FIG. 1-C are top views of some examples of respective prior art oscillating power tool attachment portions 10. FIG. 2 is a top view of a prior art blade portion 20 having a straight cutting edge. FIG. 3 is perspective view of a prior art cutting blade accessory 30 for an oscillating power tool.

A tool attachment portion 10 is affixed with a blade portion 20 to form the blade accessory 30. The tool attachment portion 10 includes an offset so that the blade portion 20 is offset from the attachment point. That is, in an assembled blade accessory 30, the tool attachment portion 10 is offset from the blade portion 20 so that the attachment portion of the tool attachment portion 10 is in a separate plane from the blade portion 20. The plane of the attachment portion of the tool attachment portion 10 is typically parallel to the plane of the blade portion 20. The blade accessory 30 is attached to an oscillating power tool via the tool attachment portion 10. An arbor attachment is utilized for attaching the tool attachment portion 10 to an oscillating power tool. Arbor attachments have varied widely and often utilize a proprietary arbor configuration. Universal arbor attachments have been developed to be compatible with many of these proprietary configurations.

Accessory attachment portions have also been developed so that a separate adapter can be affixed to (welding, for example) form a complete tool attachment portion. Such an accessory attachment portion includes a semi-circle type opening with no adapter present so that an adapter can be welded in place to complete a tool attachment portion.

The guide blade 100-L includes a tool attachment portion 540, a blade portion 220, and a deflector 550. The tool attachment portion angles out on both sides as it extends away from the arbor and toward the blade portion 220. The blade portion 220 matches the angular direction of the tool attachment portion 540 as the blade portion 220 widens toward a flat scraping edge opposite the tool attachment portion 540.

In an alternative embodiment (not shown), the blade portion 220 of the guide blade 100-L includes a cutting edge rather than a flat edge opposite the tool attachment portion 540.

The deflector 550 extends along the width of the blade portion 220 of guide blade 100-L. The deflector curves up and slightly away from the tool attachment portion 540 of the guide blade 100-L. The oscillating motion of the guide blade 100-L peels materials such as linoleum, wallpaper and such like and the deflector curls the materials up and away from the multi-tool. In this way, the materials are removed without the need for continuously stopping to clean out the mechanism of the multi-tool.

It should be appreciated by those skilled in the art that the scraper guide blade functionality described in regards to FIG. 18-A and FIG. 18-B are also useful for reciprocating power tools such as a recipro saw, a sabre saw, or SAWZALL®, for example. The addition of a deflector to a scraper type blade provides the same functionality of turning the materials away from the reciprocating power tool and reduces or eliminates the need for stopping to clean out the mechanism.

FIG. 19-A is a top view of an oscillating guide blade 100-M for lengthwise pipe cutting. FIG. 19-B is a side view of the guide blade 100-M. The guide blade 100-M includes a tool attachment portion 560, a rounded cutting blade 240, and a lengthwise pipe guide 570a, 570b.

The lengthwise pipe guide 570a, 570b includes two portions that extend outward from each side of the rounded cutting blade 240 and further extends beyond the cutting edge 242 on each side.

The spacing between the outer edge portions of the lengthwise pipe guide 570a, 570b approximates the diameter of the pipe to be cut. Since the spacing of the lengthwise pipe guide approximates the pipe to be cut, the edge portions of the lengthwise pipe guide 570a, 570b, provide for keeping the rounded cutting blade 240 aligned properly along the length of the pipe.

It should be appreciated by those skilled in the art that the lengthwise pipe-cutting guide blade functionality described in regards to FIG. 19-A and FIG. 19-B are also useful for reciprocating power tools such as a recipro saw, a sabre saw, or SAWZALL®, for example. The addition of a lengthwise pipe guide along both sides of the blade provides the same functionality of keeping the rounded cutting blade 240 aligned properly along the length of the pipe.

In one embodiment, the blade portion 240 includes a single cutting edge 242 extending in a semi-circular manner at a distance from the tool attachment portion 560, and extending away from the blade portion 240 in a curvilinear fashion toward separate planes equidistant from the blade portion 240 in opposite directions, and the guide portion or pipe guide 570a, 570b extends in the separate planes beyond the single cutting edge 242, to provide for cutting linearly along a pipe length.

FIG. 20 is a top view of an oscillating guide blade 100-N for cleaning paint cans and lids. The guide blade 100-N includes a tool attachment base 11, a blade portion 250, and a basin 610. In the illustrated embodiment, the blade portion 210 is made from high carbon-steel, bi-metal, titanium, and/or any other material combinations that are known in the industry for providing oscillating power tool blades. The guide blade 100-N provides for ease of cleaning the paint out of the grooves at the top edge of the paint can and/or the grooves of the lid so that the paint can is effectively sealed to prevent excess air and climatic changes in the environment from deteriorating the paint further. In this way, the paint is preserved for a longer period of time.

The blade portion 250 includes two groove patterns at the end opposite the too attachment base 11. The groove pattern 252 matches the grooves in a typical or standard paint can lid. As such, the blade portion 250 is aligned so that groove pattern 252 mates with the paint can lid, and the oscillation of the multi-tool serves to scrape the paint from the paint can grooves as the groove pattern 252 is moved around the circumference of the top of the paint can.

The basin 610 descends from the blade portion 250 and matches the inner curvature of the paint can. In the illustrated embodiment, the curvature is aligned for a counterclockwise motion of the blade portion 250 around the top of the paint can. The depth of the basin is sufficient to contain the amount of paint that will be removed from the lid portion, but not so much as to extend into the paint within the can. As the multi-tool operates the oscillating guide blade 100-N, the oscillation removes the paint, and the scraped or removed paint falls into the basin 610. The paint within the can remains clean and the lid is provided with an adequate seal to prevent air from entering the container.

In various embodiments, the basin 610 is made from plastic, canvas, metal, or any other material suitable for receiving the scraped paint from the lid.

The groove pattern 254 does not typically include a basin, though it is within the scope of this disclosure that a second basin (not shown) may be included. The groove pattern 254 is utilized in the same manner so that the oscillating guide blade 100-N, removes paint from the lid. In combination then, a clean paint can top and a clean paint can lid provide for a properly sealed can so that the paint contents may be preserved.

Those skilled in the art will recognize that various oscillating guide blades are provided as guides for use with oscillating power tools (multi-tools) and to provide for cleaner and more precise cuts.

It should be emphasized that the above-described embodiments of the present disclosure are merely possible examples of implementations set forth for a clear understanding of the principles of the disclosure. Many variations and modifications may be made to the above-described embodiment(s) without departing substantially from the spirit and principles of the disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
