[0001] The applicant claims the benefit of the filing date of U.S. Application No. 62,895,703. TECHNICAL FIELD

[0002] The present invention relates to a rotary tool device attachment and alignment system. BACKGROUND OF THE INVENTION

[0003] Do-it-yourself (“DIY”) workers as well as skilled craftsmen often experience the need to learn, enhance, improve, and strengthen their abilities and techniques. Users of rotary equipment may seek the techniques required to perform a specific task, or may need guidance to help use a tool, such as a drill bit, correctly for the first time. Skilled craftsmen may wish to become better at their trade and may need to increase precision, or may need to simplify tasks that require precision in multiple repeated operations.

[0004] For example, it is difficult to maintain proper alignment of a rotary drilling tool with a work surface (such as a workpiece being drilled by a handheld electric drill). This is especially true when drilling over a long distance, as a slight misalignment of the rotary drilling tool relative to the work surface will ultimately result in a non-perpendicular or severely angled drill hole. Additionally, it is difficult to know the depth of a drill bit as it penetrates the work surface. This is especially true for longer drilling setups or tasks that require a specific drill bit depth in repeated drilling operations.

[0005] Many standard rotary tools are limited to their primary functions and do not provide a way to add features and functions that can be used to enhance, improve, or strengthen the tool. Many secondary features provided by standard rotary tools, such as work surface illumination or bubble level alignment on an electric drill, are often ineffective or inadequate. A bubble level is only effective on a plane where gravity is restricted, and the built-in electric drill illumination is typically off-center and too dim.

[0006] There has been a continuing need for a simple way to expand or add features and functions to enhance, improve, or strengthen the capabilities of rotary tools, thereby enhancing the abilities and skills of rotary tool users. Additionally, there is a need to provide new features and functions in a universal form so that they can work and integrate easily with various rotary tool brands and models. SUMMARY OF THE INVENTION

[0007] The present invention relates to a device designed to be magnetically attached to a chuck or rotating element of a rotary tool and to support an additional tool. The present invention relates to a rotary tool equipment attachment system that can be used in alignment systems, depth penetration measurement systems, guidance and control systems, calibration systems, lighting, and debris removal, cleaning, grinding, cutting, or polishing. In combination with some embodiments, the device or system can be used to attach an element to a rotating element in applications that do not require high torque. In other applications, powerful neodymium magnets are used to firmly hold the device in place even when a large torque is applied to the device. Embodiments of the present invention can be used with different rotary tools, including drills, rotary cutting devices such as circular saws, miter saws, grinders, or stationary rotary tools such as drill presses, milling machines, or lathes. Embodiments can include other elements that enhance, improve, add, or facilitate the use of rotary tools, including but not limited to a work surface alignment system, a drilling depth system, a work surface light, a fan for removing debris from the work surface, or a work surface guidance and control system. Embodiments of the device can also be used to hold cutting, cleaning, grinding, cutting, grinding, or polishing elements, and the user can quickly and easily replace the corresponding elements of different grades. Embodiments can also be used for calibration operations, such as mill movement, which ensures that the grinding head is perpendicular to the X and Y axes of the grinding table.

[0008] Embodiments of the present invention include a device having one or more magnets configured to be magnetically attached to a surface of a rotating portion of a rotary tool such that when the rotating portion of the rotary tool rotates, the device also rotates. In one embodiment, the device includes a spacer element for aligning the device with the rotating portion of the rotary tool such that the two are aligned during rotation.

[0009] In an embodiment, the rotary tool is a rotary drilling device such as a drill. In other embodiments, the device is used with a rotary cutting device such as a miter saw or a grinder. As disclosed herein, a device according to an embodiment of the present invention includes one or more magnets configured to be magnetically attached to a rotating element of a rotary tool such that when the rotating portion of the rotary tool rotates, the device for supporting other tools also rotates. Embodiments of the present invention optionally include an alignment spacer ring device that centers the device on the axis of rotation of the rotary tool by engaging the chuck. The implementation of these embodiments can be used for various purposes, such as a laser or a focused beam that helps the user align a cutting element or a drill bit or for depth measurement during use when attached to the rotating portion of the rotary tool.

[0010] The advantages of the present invention are that a single magnet or a set of magnets fixed to the device can be used to attach the device to a variety of rotary tools, such as electric drills of different brands and models. In addition, a single magnet or a set of magnets establish a non-permanent connection between the rotating part of the rotary tool and the device, so the device can be quickly attached to or removed from the rotary tool as needed without mechanical attachment and / or release mechanisms. The magnetic connection also serves as a safety mechanism because if the device is obstructed by an external object during rotation, the device will disconnect from the rotating part of the rotary tool.

[0011] Another advantage of the embodiment provides alignment of the rotating part of the rotary tool and the device. Device alignment allows the entire system to operate more efficiently along a single common axis of rotation, which can provide stability, balance, efficiency, and precision during operation.

[0012] The present invention and related embodiments further disclose improvements to U.S. Patent No. 7,992,311, U.S. Patent No. 10,150,167, U.S. Patent No. 10,739,127, and U.S. Patent Application No. 16 / 418,256, which are incorporated herein by reference. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The present invention generally relates to attachment and alignment systems and devices for rotary tool equipment. The rotary tool that can be used with the present invention can be anything known in the art, such as a rotary drilling device like a drill or a rotary cutting device like a circular saw, and the device can be anything that enhances, improves, adds to, or facilitates the rotary tool, including but not limited to a work surface alignment system, a drilling depth system, a work surface light, a work surface guidance system, a debris removal system, or a cutting, grinding, cleaning, polishing, or material application or removal system.

[0056] For simplicity, the embodiments described in this specification are provided in the context of an electric drill and a circular saw, but can also be applied to other types of rotary tools known in the art, including but not limited to construction tools, manufacturing tools (such as grinders, lathes, or drill presses), maintenance tools, lawn care tools, earthmoving tools, or agricultural tools. Additionally, the rotary tool can simply be a rotating element of a larger system or mechanism, such as a flywheel, a crankshaft, a gear, a pulley, or a wheel.

[0057] Magnetic Attachment Embodiments

[0058] One feature of an embodiment of the system is that a single magnet or a group of magnets can be used to attach the device to a variety of rotary tools, such as electric drills of different brands and models.

[0059] In addition, a single magnet or a group of magnets creates a non-permanent connection to the rotating portion of the rotary tool, so the associated device can be quickly attached or removed from the rotary tool as needed, without the need for mechanical attachment and release mechanisms.

[0060] The non-permanent magnetic connection also serves as a safety mechanism, because if the device is obstructed by an external object during rotation or if the load increases and there is a risk of damage to the motor and / or the work surface, the device will disconnect from the rotating portion of the rotary tool.

[0061] One or more magnets for attaching a device to a rotating portion of a rotary tool can be permanent magnets, electromagnets, or some combination thereof. Permanent magnets retain their magnetism, while electromagnets require a power source and can be turned on or off. Permanent magnets typically come in a variety of types, including but not limited to neodymium iron boron, samarium cobalt, alnico alloys, ceramic ferrites, and other types known in the art.

[0062] The magnet configuration can be a single magnet whose properties such as shape, size, magnetization direction, grade, etc. contribute to the purposes of the implementation, or two or more magnets whose individual properties such as shape, size, magnetization direction, grade, etc. and group properties such as arrangement, orientation, etc. are conducive to achieving the purposes of the implementation.

[0063] Another characteristic of the magnet configuration is the placement or position of one or more magnets within the device relative to the corresponding metal regions or surfaces of the rotary tool. When in direct contact with another metal object (or another properly oriented magnet or group of magnets), one or a group of magnets will produce its strongest magnetic attraction field. Therefore, the placement and position of the magnets within or on the device, and the resulting magnetic attraction field, must also contribute to the purposes of the implementation. In several embodiments included in this specification, there is a minimum separation or no separation between the magnet (or group of magnets) within or on the device and the metal region or surface of the rotary tool. The minimum separation or no separation produces a strong magnetic attraction field. In several other embodiments, this arrangement is opposite to the magnet (or group of magnets) in the rotary tool and the metal ring or surface within or on the device. In this embodiment, there is also a minimum separation or no separation between the magnet (or group of magnets) in the rotary tool and the metal ring or surface within or on the device. In yet another embodiment included in this specification, both the rotating portion of the rotary tool and the device contain magnets that are oriented to magnetically attract each other. In this embodiment, there is also a minimum separation or no separation between the magnet (or group of magnets) in the rotating portion of the rotary tool and the magnet (or group of magnets) within or on the device.

[0064] Now referring to Figure 1 , in a first embodiment of the present invention, the magnet (not shown) is a single permanent annular element fixed within the device 2, and the cutting tool 4 includes a drill bit. As Figure 2 can be seen, the magnet 1 is an annular element having an inner diameter 3 that is large enough to insert and pass through the largest possible cutting tool 4 that can be assembled within the jaws 5 of the rotating element 6. The magnet 1 can be neodymium iron boron, samarium cobalt, alnico alloys, ceramic ferrites, and other types known in the art. In this embodiment, the shape of the device 2 allows it to be almost transparent when rotating, which allows the user to see the surface being engaged by the cutting tool 4. Referring toFigure 2 , the inner diameter 3 of the annular magnet 1 (and the opening of the cover 7) is large enough to accommodate various sizes of cutting tools that can be held in the jaws 5 of the chuck 6. The magnet 1 is used to attach the device 2 to the surface 29 of the rotating part 6 of the rotary tool. In this embodiment, the device 2 includes a laser and optics in the optical assembly 9 for work surface alignment. One or more laser projections emerge from one or more windows 16 in the device 2. In a further embodiment, additional laser and optical combinations can be provided for depth detection, work surface alignment, or both.

[0065] Figure 3 A exploded view of the back of the device 2 is depicted, showing the exposed magnet 1 and the cover 7 that covers the magnet 1 within the device 2. Figure 3 Also depicted is the annular cavity 8 within the device 2 that receives the magnet 1, and a power switch 21 that can turn on or off one or more lasers in the device 2.

[0066] Figure 4 is Figure 1 , Figure 2 and Figure 3 A cross-sectional view of the illustrated embodiment, showing the arrangement in which the device 2 engages with the rotating element 6 of the rotary tool. As shown here, the cover 7 contacts the surface 29 of the rotating element 6 of the rotary tool. Immediately behind the cover 7 is the magnet 1, which is magnetically attracted to the surface 29 of the rotating element 6 of the rotary tool. Figure 4 Also depicted is the cavity 13 in the device 2, which is large enough to accommodate two jaws 5 of the chuck 6 and various sizes of cutting tools that can be held in the jaws 5 of the chuck 6. The hole 12 in front of the device is also large enough to accommodate various sizes of cutting tools that can be held in the jaws 5 of the chuck 6.

[0067] Figure 5 Depicts a partial cross-sectional view of the embodiment along the plane that encloses the optical assembly 9 within the device 2 and the rotating part 6 of the rotary tool from Figure 1 , Figure 2 , Figure 3 and Figure 4 . In this embodiment, the optical assembly 9 includes a laser 22, two beam splitters 23 and 24, and a first side mirror 25 that projects a light beam (not shown) through the window 16 and operates in combination to provide a work surface alignment function. Also depicted is a battery 20 that powers the laser. In a further embodiment, additional laser and optical device combinations can be provided for depth detection, or depth detection and work surface alignment, and a separate lamp or group of lamps for illuminating the work surface. Further embodiments utilize several magnets arranged in a pattern relative to a single annular magnet 1, or one or more electromagnets that are also powered by the battery 20.

[0068] Alternatively, as Figure 6 shown, a single permanent toroidal magnet 55 is attached to the rotating portion 46 of the rotary tool. In this embodiment, the device 42 includes an attached or embedded ferrous metal ring 41 having a diameter similar to that of the toroidal magnet 55 fixed to the rotating portion 46 of the rotary tool. In this embodiment, the metal ring 41 is a magnetically attractive metal material, such as iron, steel, cobalt, nickel, or other magnetically attractive materials known in the art. In this embodiment, the inner diameters of the toroidal magnet 55 and the metal ring 41 are also large enough to allow the insertion of the cutting tool 44 (e.g., a drill bit for operation) and the jaws 45. Thus, the ferrous metal ring 41 is used to attach the device 42 to the magnet 55, which is fixed or built into the rotating portion 46 of the rotary tool.

[0069] In this embodiment, the device 42 includes a laser and optics in the optical assembly 49 for work surface alignment. One or more laser projections emerge from one or more windows 56 in the device 42. In a further embodiment, additional combinations of lasers and optics may be provided for depth detection, work surface alignment, or both.

[0070] Figure 7 A disassembled view of the back of Figure 6 is depicted, showing the ferrous metal ring 41 exposed, and a cover 47 that covers the ferrous metal ring 41 within the device 42. Figure 7 Also depicted is an annular cavity 48 within the device 42 that receives the ferrous metal ring 41, and a power switch 51 that can turn on or off one or more lasers in the device 42.

[0071] Figure 8 is Figure 6 and Figure 7 a cross-sectional view of the device of Figure 8 showing the arrangement of the device 42 engaged with the rotating element 46 of the rotary tool. As shown here, the cover 47 contacts the magnet 55, which is fixed or built into the rotating portion 46 of the rotary tool. Immediately behind the cover 47 is the ferrous metal ring 41, which is connected to the magnet 55 by magnetic attraction, and the magnet 55 is fixed or built into the rotating portion 46 of the rotary tool.

[0072] In a further contemplated embodiment, an electromagnet is provided in place of a permanent magnet, the permanent magnet being powered by a separate battery in a rotary tool attached to a rotating element and activatable by a switch. In a still further embodiment, an electromagnet is provided that is powered by the main power supply of the rotary tool. In an additional embodiment, a metal ring or metal surface, other shaped magnets (or magnet(s)) are oriented on the device in positions where they are permanently or temporarily fixed to a ring magnet that is permanently or temporarily fixed to the rotating portion of the rotary tool.

[0073] In Figure 9 and Figure 10 the depicted embodiment, the device 62 includes a fixed-size slot or opening 72 for the cutting tool 64, which automatically centers the device 62 on the cutting tool 64. In this embodiment, the magnet is enclosed within the device 62. When the rotating portion 66 of the rotary tool rotates, the device 62 centered on the cutting tool 64 rotates about the same axis of rotation as the rotating portion 66 of the rotary tool, which provides balance and stability. Additionally, the fixed-size slot or opening 72 may be slightly larger than the diameter of the cutting tool 64, which allows the device 62 to disconnect safely and quickly from the rotating portion 66 of the rotary tool if the device 62 is obstructed by an external object during rotation. Figure 10 A partially exploded view of the device 62 and the cutting tool 64 is depicted, where the opening 72 for the cutting tool 64 is visible. In this embodiment, the device 62 includes a laser and optics in an optical assembly 69 for work surface alignment. One or more laser projections emerge from one or more windows 76 in the device 62. In a further embodiment, additional combinations of lasers and optics may be provided for depth detection, work surface alignment, or both.

[0074] In another embodiment related to Figure 9 the device 62 includes a fixed-size slot or opening 72 centered on the drill chuck jaws rather than the cutting tool 64.

[0075] In another embodiment related to Figure 9 the device 62 includes a large slot or opening and a set of independent adjustable centering jaws, such as vise-like clamps that can be adjusted for a cutting tool 64 of a specific diameter. When the adjustable centering jaws are tightened onto or around the cutting tool, the device 62 becomes centered with the cutting tool. In this embodiment, the adjustable centering jaws can accept and automatically adjust to multiple cutting tool diameters and are not limited to a single diameter cutting tool as Figure 9 shown.

[0076] In another embodiment related to Figure 9In another related embodiment, the device includes a large slot or opening and a set of spring steel entities that force the device 62 to center on the cutting tool. In this embodiment, the spring steel can accommodate and automatically adjust to a variety of cutting tool diameters and is not limited to a single diameter cutting tool as shown in Figure 9 as shown.

[0077] In another related embodiment, the device includes a large slot or opening and a set of spring-loaded centering jaws, such as a vise-type fixture that can be automatically adjusted for a specific diameter cutting tool. When the spring-loaded centering jaws are automatically adjusted to the cutting tool, the device will be centered with the cutting tool. In this embodiment, the spring-loaded centering jaws can accommodate and automatically adjust to various cutting tool diameters and are not limited to a single diameter cutting tool as shown in Figure 9 as shown. Figure 9 as shown.

[0078] In the embodiment shown in Figures 11 - 17 , the device 82 includes a fixed-size opening 92 through a member 91 for the cutting tool 84, and this opening 92 forces the device 82 to automatically center on the cutting tool 84. In this embodiment Figure 13 , Figure 14 and Figure 15 , magnets 81 are enclosed in a device near the rear surface of the device 82 to allow it to form a magnetically coupled attachment with the rotary tool 86. However, different from the embodiments shown in Figure 9 and 10 , the fixed-size opening 92 is part of the removable member 91 and can be added or inserted into the device 82 as needed to accommodate different sizes of cutting tools. For example, a kit or system including a series of removable elements 91 can be provided, each removable element providing a specific fixed-size opening 92 and corresponding to a drill bit of a specific diameter, such as 1 / 2" round, 3 / 8" round, 1 / 4" round, 1 / 4" hex shank. This allows a single device 82 to operate with drill bits of multiple sizes by using multiple removable members 91.

[0079] Figure 11 is an isometric view of an embodiment of a rotary tool device attachment and alignment system for attaching the device 82 to the rotary part 86 of a rotary tool. This embodiment also uses a removable entity 91 to align the device 82 with the cutting tool 84. When the rotary part 86 of the rotary tool rotates, the device 82 centered on the cutting tool 84 rotates around the same rotation axis of the rotary part 86 of the rotary tool. The tool provides balance and stability. In addition, the fixed-size slot or opening 92 can be slightly larger than the diameter of the cutting tool 84, which allows the device 82 to safely and quickly disconnect from the rotary part 86 of the rotary tool if the device 82 is obstructed by an external object during rotation. Figure 12 depictsFigure 11 Partial exploded view of an embodiment, where the removable entity 91 is depicted outside the device 82. In this figure, the removable entity 91 and the compartment or cavity 95 in the device 82 are visible. In this embodiment, the compartment or cavity 95 has a fixed size, shape, and depth, allowing a series of removable entities 91 to be inserted into the device as required, each entity 91 providing a specific fixed-size opening 92 and corresponding to a drill bit of a specific diameter.

[0080] As Figure 13 seen, the magnet 81 is an annular element with an inner diameter 83 that is large enough to insert and pass through the largest possible cutting tool 84 that can be fitted within the chuck jaws 85 of the rotating element 86. 81 can be neodymium iron boron, samarium cobalt, alnico alloy, ceramic ferrite, and other types known in the art. In this embodiment, the shape of the device 82 allows it to be nearly transparent when rotating, which allows the user to see the surface engaged by the cutting tool 84. The inner diameter 83 of the annular magnet 81 (and the opening of the cover 87) is large enough to accommodate various sizes of cutting tools that can be accepted in the jaws 85 of the chuck 86. The magnet 81 is used to attach the device 82 to the rotating part 86 of the rotary tool. In this embodiment, the device 82 includes a laser and optics in the optical assembly 89 for work surface alignment. One or more laser projections emerge from one or more windows 96 in the device 82. In a further embodiment, additional combinations of lasers and optics can be provided for depth detection, work surface alignment, or both.

[0081] Now referring to Figure 13 , Figure 14 and Figure 15 , the removable entity 91 includes one or more magnetically attractive embedded elements 94. These elements include, but are not limited to, ferromagnetic materials or actual magnets. This configuration allows the removable entity 91 to be magnetically mounted into the compartment or cavity 95 based on the magnetic attraction of the annular magnet 81. In one embodiment, the embedded element(s) 94 is a ferromagnetic material that is attracted to the magnet, such as iron, steel, cobalt, nickel, or other magnetically attractive materials known in the art. In another embodiment, the embedded element(s) 94 is a small magnet that is oriented such that it is magnetically attracted to the annular magnet 81.

[0082] Figure 14 Depicts an exploded view of the back of the device 82, showing the exposed magnet 81 and the cover 87 that covers the magnet 81 within the device 82. Figure 14 Also depicted is the annular cavity 88 in the device 82 that receives the magnet 81, and the power switch 102 that can turn on or off one or more lasers in the device 82.

[0083] Figure 15 isFigures 11 - 17 A cross-sectional view of the apparatus of the illustrated embodiment, showing the arrangement of the device 82 engaged with the rotating element 86 of the rotary tool. As shown here, the cover 87 contacts the surface 99 of the rotating element 86 of the rotary tool. Immediately behind the cover 87 is the magnet 81, which is connected to the surface 99 of the rotating element 86 of the rotary tool by magnetic attraction. Figure 15 Also depicted is a cavity 93 in the device 82, which is large enough to accommodate two jaws 85 of the chuck 86 and cutting tools of various sizes that can be received in the jaws 85 of the chuck 86.

[0084] Figure 16 Depicted Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 17 Partial cross-sectional views of the embodiments in, along the plane enclosing the optical assembly 89 within the device 82 and the rotating portion 86 of the rotary tool. In this embodiment, the optical assembly 89 includes a laser 97, two beam splitters 98 and 99, and a first side mirror 100. The first side mirror 100 projects a light beam (not shown) through the window 96 and operates in combination to provide a work surface alignment function. Also depicted is a battery 101 that powers the laser. In a further embodiment, additional combinations of lasers and optics can be provided for depth detection, or both depth detection and work surface alignment, as well as a separate lamp or set of lamps that can be used to illuminate the work surface. Other embodiments can also utilize several magnets arranged in a pattern relative to a single annular magnet 81, or utilize one or more electromagnets that are also powered by the battery 101.

[0085] Figure 17 is Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16 Side views of the embodiments in. In this embodiment, the laser projections 106, 107, and 108 originating from the optical assembly 89 within the device 82 are visible. In this figure, the work surface 105, the cutting tool 84, and the removable entity 91, as well as the rotating portion 86 of the rotary tool, are also depicted.

[0086] In Figure 18 、 Figure 19 、 Figure 20 and Figure 21In the illustrated embodiment, the device 112 includes a removable cover 127 that aligns with certain features of the rotating portion 116 of the rotary tool and forces the device 112 to be centered and automatically aligned with the rotating portion 116 of the rotary tool and thus automatically aligned with the cutting tool 124. In this embodiment, the features of the rotating portion 116 of the rotary tool are the face 130 and the front chamfer edge 129. This embodiment presents advantages over previous embodiments of automatic centering on the cutting tool because the automatic centering using the rotating portion 116 of the rotary tool allows the user to operate with any cutting tool diameter on the same rotary tool without any built-in cutting tool guidance, such as Figure 10 the hole 72 in, or the removable element Fig. 91 has Figure 12 the hole 92 in. In this embodiment, the device 112 includes a laser and optics in the optical assembly 119 for work surface alignment. One or more laser projections emerge from one or more windows 126 in the device 112. In a further embodiment, additional combinations of lasers and optics can be provided for depth detection, work surface alignment, or both.

[0087] As Figure 19 、 Figure 20 and Figure 21 shown, the side 120 of the removable cover 127 facing the rotary tool mirrors the shape of the face 130 and the front chamfer edge 129 of the rotating portion 116 of the rotary tool (drill chuck) and contacts and centers with the rotating portion 116 of the rotary tool. Immediately behind the interchangeable cover 127 is a magnet 111 that is located in the annular cavity 128 of the device 112 and is connected to the face 130 of the rotating element 116 of the rotary tool by magnetic attraction. In this embodiment, the removable cover 127 has a threaded element 121 that screws onto the threaded element 125 on the device 112. This allows for replacement of the cover 127 due to wear, or more importantly, the ability to use the same device 112 with different sets of chuck-specific removable covers 127, each cover 127 being individually mounted on a unique brand and model of chuck and aligned with the chuck center.

[0088] Figure 21 is Figure 18 、 Figure 19 and Figure 20 a cross-sectional view of the device, showing the arrangement in which the device 112 engages with the rotating element 116 of the rotary tool. As shown here, the removable cover 127 contacts both the face 130 and the front chamfer edge 129 of the rotating element 116 of the rotary tool. Immediately behind the cover 127 is a magnet 111 that is connected to the face 130 of the rotating element 116 of the rotary tool by magnetic attraction. The removable cover 127 has a threaded element 121 that screws onto the threaded element 125 on the device 112. Figure 21Also depicted in the device 112 is a cavity 120 large enough to accommodate the two jaws 115 of the chuck 116 and cutting tools of various sizes, which can be received in the jaws 115 of the chuck 116. The hole 122 in front of the device 112 is also large enough to accommodate cutting tools of various sizes that can be received in the jaws 115 of the chuck 116.

[0089] In another related embodiment, the cover 127 includes small circular, semi-circular or other shaped protrusions aligned with the chuck jaw holes in the rotating part 116 of the rotary tool.

[0090] In Figure 38 , Figure 39 and Figure 40 In the illustrated embodiments, the device 300 includes an annular or ring-shaped portion 310. The magnet is a single permanent or ring magnet 301, which is permanently or temporarily fixed to the device 300 or on the device 300. In this embodiment, the inner diameter 303 of the ring magnet 301 is generally large enough to insert and pass through the largest possible cutting tool 304 for the intended operation (e.g., a 1 / 2-inch drill bit if the rotary tool is a drill). The inner diameter 303 of the ring magnet 301 (and the opening in the cover 307) is also generally large enough to attach a cutting tool holder mechanism such as the jaws 305 of the chuck 306 to the cutting tool 304. The magnet 301 is used to attach the device 300 to the surface 315 of the rotating part 306 of the rotary tool.

[0091] Figure 39 An exploded view of the back of the device 300 is depicted, where the magnet 301 is exposed together with the cover 307 or the part of the device housing that covers or encloses the cover 307 within the device 300. Figure 39 Also depicted is a slot 308 within the device 300, into which the magnet 301 is fitted. Figure 40 Depicted is from Figure 38 and Figure 39 A cross-sectional view of the embodiments. In this embodiment, the device 300 includes one or more lasers and optics 309 for work surface alignment. In a further embodiment, additional combinations of lasers and optics can be provided for depth detection, work surface alignment, or both. Figures 38 - 40 An advantage of the embodiment in is the annular or ring-shaped element 310, which provides an additional safety element by preventing potential obstacles (such as external objects) from interfering with the device 300 during rotation. The annular or ring-shaped element 310 also includes opening portions 313 and 314, which reduce the total weight of the device 300. The same annular or ring-shaped element 310 can also be applied to other rotating embodiments herein.

[0092] In Figure 41 and Figure 42In another embodiment depicted, the magnet is a set of permanent, rectangular (or other) shaped magnets 321, which are arranged in a circular pattern (at the 0, 90, 180, and 270 degree positions in this embodiment) and are fixed either permanently or temporarily to the device 320. In this embodiment, the central space between all four magnets 323 is typically large enough to insert and pass through the largest possible cutting tool 322 for the intended operation (e.g., a 1 / 2 inch drill bit if the rotary tool is a drill). The inner diameter 323 (and the opening in the cover 326) is also typically large enough to attach a cutting tool holder mechanism such as jaws 325 of a chuck 328 to the cutting tool 322. The magnets 321 are used to attach the device 320 to the rotating part 328 of the cutting tool. Figure 42 A disassembled view of the back of the device 320 is depicted, where the magnets 321 are exposed together with the cover 326 or the part of the device housing that covers or encloses them within the device 320. Figure 42 A slot 327 within the device 320 is also depicted, into which the magnets 321 are fitted. In this embodiment, the device 320 includes one or more lasers and optics 329 for work surface alignment. In a further embodiment, additional combinations of lasers and optics can be provided for depth detection, work surface alignment, or both.

[0093] In a further embodiment similar to Figures 38 - 42 the magnet 301 or magnet 321 is an electromagnetic magnet rather than a permanent magnet. In this embodiment, one or more electromagnetic magnets can also be turned on or off and are powered by a battery internal or adjacent to the device.

[0094] Now returning to reference Figure 22 , the device 132 includes a work surface illumination system having light sources 140, 141, 142, and 143 that, when connected to the rotating part 136 of the rotary tool, are directed towards the work surface to provide illumination. The cutting tool 134 passes through the device 132, and the device 132 is held on the rotating part 136 of the rotary tool. As seen in the disassembled Figure 23 this embodiment includes a single permanent ring magnet 131 fitted into the device 132. The inner diameter 145 of the ring magnet 131 and the opening in the cover 133 are large enough to insert and transport and pass through the largest possible cutting tool 134 for the intended operation, such as a drill bit. The inner diameter 145 of the ring magnet 131 and the cover 133 is large enough to attach a cutting tool holding mechanism such as jaws 135 of a chuck 136 to various sized cutting tools. The magnet 131 is used to attach the device 132 to the rotating part 136 of the rotary tool.

[0095] Figure 24Depicts an exploded view of the back of device 132, where magnet 131 is exposed along with cover 133, which covers or encloses magnet 131 within device 132. The figure also depicts an annular cavity 146 disposed within device 132 to receive magnet 131.

[0096] In an embodiment, one or more light sources 140, 141, 142, and 143 are powered by a battery, and the illumination can be triggered by a power switch. In another embodiment, a sensor is provided that detects the rotation of device 132 and triggers a switch in response to illuminate the light sources.

[0097] Figure 25 is Figure 22 、 Figure 23 and Figure 24 A cross-sectional view of the device shows the arrangement of device 132 meshing with the rotating element 136 of the rotary tool and two of the four light sources 140 and 142. As shown, cover 133 contacts the surface 147 of the rotating element 136 of the rotary tool. Immediately behind cover 133 is magnet 131, which is connected to the surface 147 of the rotating element 136 of the rotary tool by magnetic attraction. Figure 25 Also depicted is cavity 148 in device 132, which is large enough to accommodate two jaws 135 of chuck 136 and various sizes of cutting tools that can be received in the jaws 135 of chuck 136. The hole 149 in front of the device is also large enough to accommodate various sizes of cutting tools that can be received in the jaws 135 of chuck 136.

[0098] The light sources in device 132 can be any light sources known in the art, including but not limited to LEDs. Additionally, the number, location, arrangement, and other characteristics (such as color or brightness) of the light sources may vary.

[0099] Figures 22 to 25 Other embodiments of the device in may also optionally include any method or mechanism defined to center device 132 on the rotating element 136 of the rotary tool. This can include any centering method or mechanism, or related centering method or mechanism, outlined in the embodiments depicted in Figures 9 to 21 including but not limited to static centering on the cutting tool, dynamic centering on the cutting tool, centering on the cutting tool by a removable entity 91, as in the embodiment in Figures 12 - 17 or centering on the rotating portion of the rotating element, such as in the embodiment in Figures 18 - 21 which is capable of using the same device with a set of chuck-specific removable covers 127, each chuck-specific removable cover 127 being individually assembled to a unique brand and model of chuck and being centered with the unique brand and model of chuck.

[0100] In Figure 26, Figure 27 and Figure 28 In the embodiments of the invention depicted in Figure 27 and Figure 28 , device 152 interacts with a separate device (not depicted) on a work surface (not depicted) via a laser 160. When attached to the rotating portion 156 of a rotary tool that includes a cutting tool 154, device 152 that includes laser 160 rotates with the rotating portion 156 of the rotary tool. This motion creates a generally circular rotational projection on a separate device (not depicted) disposed on the work surface (not depicted). The separate device (not depicted) on the work surface (not depicted) can use this rotational projection to determine work surface alignment and / or drill bit depth. The magnet is a single permanent toroidal magnet 151 that is permanently or temporarily fixed within or on device 152. In this embodiment, the inner diameter 160 of the toroidal magnet 151 and the opening in the cover 153 are generally large enough to allow the insertion and passage of the largest possible cutting tool 154. The inner diameter 160 of the toroidal magnet 151 and the cover 153 are large enough to allow a cutting tool holder mechanism, such as the jaws 155 of a chuck 156, to be attached to the cutting tool 154. Magnet 151 is used to attach device 152 to the surface 157 of the rotating portion 156 of the rotary tool. Laser 163 is powered by an internal battery, and its projected beam can be triggered by a power switch. In an alternative embodiment, the laser is triggered by the rotation of the device.

[0105] In [[ ]] Figure 33 , Figure 34 and Figure 35 In the embodiments shown, the rotating tool is a rotating sawing-type tool, such as a circular saw or a miter saw. In this embodiment, the device 260 includes a laser 261 attached to a side surface of a saw blade 262. As the saw blade 262 rotates, the laser 261 presents a linear path on the working surface, which serves as a guiding line for the saw blade 262. In this embodiment, the device 260 is magnetically connected to a portion of a hex bolt 263 that secures the saw blade 262 to the rotating saw. The device includes one or more magnets 264 that are magnetically attached to the hex bolt 263. Since the hex bolt 263 is located at the center of rotation, the hex bolt 263 serves as a device for aligning with the axis of rotation of the rotating saw. Various rotating saws also include a washer 265 or spacer between the saw blade 262 and the head 266 of the hex bolt 263. The device 260 may optionally cover the entire head 266 of the hex bolt 263 or some portion thereof.

[0106] In [[ ]] Figure 36 and Figure 37 In the embodiments shown, the device 270 includes a laser 271 and a magnet 272.

Those of ordinary skill in the art will appreciate that in this embodiment, the device 270 may be magnetically attached around a central portion of the saw blade 273, which is located on a rotating saw such as a circular saw or a miter saw. As the saw and the rotating portion of the saw blade 273 rotate, the laser 271 presents a linear path on the working surface, which serves as a guiding line for the saw blade 273. The inner diameter 274 of the device 270 is circular, and thus can be aligned concentrically around the central portion 275 of the saw blade.
