Description
MAGNETIC BRACKET FOR HOLDING "A MULTI-BIT DUAL-MODE
SCREWDRIVER FOR EITHER MANUAL OR POWERED ACTUATION"
Background of the Invention The present invention is a means for temporarily attaching a screwdriver to the plastic housing of a handheld drill. More specifically: the invention is a bracket for attaching my "Multi-Bit Dual-Mode Screwdriver For Either Manual Or Powered Actuation" to a handheld electric drill such that it can be more effectively used in both its manual and its powered its operational modes..
The present invention is conceived to exploit the physical and magnetic characteristics of my previous invention entitled "Multi-Bit Dual-Mode Screwdriver For Either Manual Or Powered Actuation". That invention is a pending PCT
application (WO/2006/102737). This dual-mode screwdriver has been commercialized under the trade name "Scruzol" and for brevity is hereinafter referred to as a "Scruzol" when describing the present invention.
A Scruzol utilizes a reversible shape that enables it to be either handheld or chucked in an electric drill. Users will therefore often wish to keep their Scruzol and electric drill in close proximity to each other so that both handheld and power-driven usage modes can be more easily applied to varying task requirements. When used in its power-driven mode, the Scruzol's shaft is held in the drill's chuck, thereby forming a single tool.
However when the drill is being used for piercing holes, the Scruzol must be removed and replaced with a drill bit, thereby requiring that the Scruzol be temporarily stored until it is needed again for power-driving screwdriver bits. Ideally, the Scruzol would be stored integral to the drill for convenience and to prevent loss however, since drills are not designed to accommodate such storage, there is no obvious way to do so. It is therefore a goal of the present invention to provide a specialized bracket that efficiently holds a Scruzol onto the body of typical existing electric drills.
When devising such a holding bracket it's important to consider certain details and characteristics of the preferred embodiment of a Scruzol (see Figure 3). That preferred, commercialized embodiment utilizes a strong internal ring-shaped magnet to retain spare screwdriver bits within six open-sided storage slots disposed around the exterior its cylindrical handle. The presence of this strong bit-storage magnet suggests that an optimal drill holding bracket should exploit the magnetic force of said magnet to store the entire Scruzol onto the drill housing. It is also important to consider the disposition the 12 stored '/4" hexagonal, steel screwdriver bits inside their six open-sided storage slots. Their disposition with respect to the large central ring magnet engenders a magnetic circuit through all the stored bits that will cause their storage handle to stick to a metal object such as a steel filing cabinet, thereby providing a magnetic means of conveniently storing the Scruzol in various work scenarios. For example; a mechanic working underneath automobile can conveniently store their Scruzol onto its muffler while dismantling nearby components.
Another pertinent characteristic of a Scruzol's configuration is that, due to the protrusion of its cylindrical handle in between its six storage slots, only a single vertex of each stored screwdriver bit can come into contact with a flat external anchor object such as the side of a filing cabinet. The six plastic handle protrusions thereby prevent the coplanar facets of circumferentially adjacent stored bits from simultaneously contacting the flat external anchor surface which would provide a large magnetic contact surface which would stabilize the stored Scruzol from rolling along the flat anchor surface.
Another pertinent characteristic of a Scruzol is that small metal objects such as steel drill bits, screws, washers etc are magnetically attracted to its handle and once they've become stuck onto it will remain there until removed by the user.

Furthermore, it would be desirable to provide a Scruzol storage bracket that is integral to the housing of newly manufactured drills.
Summary of the Invention To achieve the desired functionality while exploiting the above mentioned characteristics of my previous "Scruzol" invention, a metal bracket is affixed to an electric drill using an adhesive strip. Said bracket that is formed from a length of U-shaped channel having a channel depth sufficient to permit the protrusions of a Scruzol's plastic handle from preventing the bracket from making magnetic contact onto the full length of the magnetically energized screwdriver bits stored in its handle.

Detailed Description.
Figure 1 illustrates usage of a "Scruzol" in its power-driven mode. The shaft of Scruzol 1 is gripped in the chuck of typical battery-powered electric drill 2, thereby permitting the user to power-drive a screwdriver bit. Handle 6 stores a plurality of interchangeable spare bits configured to drive different screw head shapes.
Figure 2 illustrates the drill of Figure 1 when configured for drilling holes with a twist drill 3. The Scruzol 1 has been removed from the drill and replaced with drill 3 and is therefore available for use in its handheld mode of operation. While not in use, the Scruzol must be stored separately from drill 2, thereby posing an inconvenience to the user.
Figure 3 is a large-scale view showing details of a Scruzol. Plastic handle 6 is formed over shaft 5 for gripping while the Scruzol is being used in its manually driven mode. The exposed portion of shaft 5 is for affixing into the chuck of a drill while the Scruzol is being used in its power-driven mode. Shaft 5 has a first bit socket 9 formed in its handle end for use in power-driven mode and a second bit-socket formed in its exposed end for use in manual-driven mode. Handle 6 includes six open-sided hexagonal screwdriver bit storage slots 10, each slot being bisected by axially polarized ring magnet 4 to magnetically retain the set of 12 variously-tipped screwdriver bits 7. When magnetically retained from sliding out of their storage slots, the 12 bits form a magnetic circuit which will attract nearby magnetically attractable objects. Since ring magnet 4 typically has a high-performance neodymium composition, the Scruzol handle 6 is attracted strongly enough that it can remain stuck onto vertical surfaces such as a fridge door. The present invention exploits this unique characteristic of a Scruzol to provide a storage bracket.
Figure 4 is an axial view onto the Scruzol of Fig. 3 illustrating how the magnetic and non-magnetic portions of its handle interact to limit the strength of the magnetic storage effect described above. Rectangle 12 represents a metal, magnetically attractable planar object such as a steel fridge door onto which a user might wish to conveniently store their Scruzol. It's evident that the stored screwdriver bit 7a exerts a strong magnetic attraction to planar object 12 however it's also evident that the curved protrusion of the plastic handle 6 that is required to retain the bits in their respective storage slots will be tangent to object 12 and thereby prevent adjacent bit 7b from coming into contact with object 12. Handle 6 thereby limits the combined magnetic attraction of bits 7a and 7b and weakens the Scruzols desired magnetic storage effect. Furthermore, since the contact points of handle 6 and bit 7a onto object 12 are very close together, any rotational force that is applied to the Scruzol will easily pry bit 7a away from object 12 and thereby cause the storage effect to rapidly fail. In order to prevent gravity from causing this failure mode, the Scruzol must be magnetically stored into a flat surface with its axis vertical and while that is easy to do in a static application, it prevents securely attaching the Scruzol to a dynamic object such as a handheld electric drill.
Figure 4 also illustrates the present invention and how it works. Bracket 11 is a U-shaped channel of magnetically attractable metal having a channel deep enough that the curved portion of handle 6 cannot interfere with the bracket's contact onto adjacent screwdriver bits 7c and 7d. Thus the magnetic attraction onto both bits is fully realized and its anti-rotational geometry is more spaced apart and thus far more stable than that provided by flat anchoring surface 12.
Figure 7 illustrates a drill which has had the bracket of Figure 5 moulded into its plastic housing during its manufacture;
Figure 8 illustrates a Scruzol stored onto a drill according to the present invention and also serving as a magnetic parts holder for spare twist drills, screws, screwdriver bits or other small parts.

Figure 4 also illustrates the present invention and how it works. Bracket 11 is a U-shaped channel of magnetically attractable metal having a channel deep enough that the curved portion of handle 6 cannot interfere with the bracket's contact onto adjacent screwdriver bits 7c and 7d. Thus the magnetic attraction onto both bits is fully realized and its anti-rotational geometry is more spaced apart and thus far more stable than that provided by flat anchoring surface 12.
Figure 5 is an oblique view of a Scruzol 1 magnetically affixed to an existing electric drill 2 using the bracket 11 shown in Figure 4. Bracket 11 is long and wide enough to have significant magnetic contact onto screwdriver bits 7c, 7d and 7e and thus provides a strong and stable magnetic bond between Scruzol 1 and bracket 11. The illustrated bracket's overall dimensions are 2" x 0.5" x.125". Since drill 2 typically has a somewhat curved outer casing made of moulded plastic, adhesive strip 13 is provided for bonding bracket 11 onto any convenient location on drill 2, thereby permitting the user to store the Scruzol conveniently onto the drill while it's being used for piercing holes as, as shown in Figure 2.
Bonding bracket 11 securely to drill requires a suitably strong double-sided tape such as to "3M Very High Bond Double-Sided Foam Tape #4955". This type of tape provides a strong adhesive action and it also has a compliant foam core that conforms to the gentle curvature typically found on electric drill housings.
Figure 6 is a large-scale view of the metal bracket shown in Fig. 5. It is U-shaped channel having a base portion 16, a left side portion 14 and a right side portion 15, said side portions having a height that is sufficient to provide adequate clearance for the curved cylindrical handle of a Scruzol as illustrated in Figure 4. In the case of the illustrated Scruzol, the height of sides 14 and 15 above base portion 16 is approximately 1/16th of an inch and the interior width of the channel is approximately 3/8ths of an inch.
The illustrated thickness of the foam dual-sided adhesive strip 13 is approximately 3/32".
If affixed to a fairly flat drill housing using a suitable adhesive strip, the simple channel bracket shown in Figure 5 will perform adequately however in some instances an existing drill housing drill housing will be sufficiently curved that the foam core of adhesive strip 13 isn't deep and compliant enough to provide a strong bond. To accommodate such scenarios, base 16 may optionally include weakening groove 18 that permits the user to bend bracket 11 longitudinally to better match their drill housing. Weakening groove also provides a slight convexity that permits adhesive strip 13 to better mate to typical drill housings. To enable a user to mount bracket I 1 onto particularly difficult to bond drill housing materials or to enable the bracket to be screwed onto a desirable, non-drill object such as a wooden workbench, one or more countersunk mounting holes 17 may optionally be provided.
Figure 7 illustrates a custom manufactured drill 19 that has been optimized for use with a Scruzol by moulding the left and right side portions of the bracket 11 shown in Figure 6 directly into the drill's plastic housing. The resulting left and right magnetically attractive ridges 21 a and 21 b protrude from the drill in the optimal configuration for attaching said Scruzol as required. The integrated bracket comprised of ridges 21a and 21b may also be positioned on the sides of drill 19 or onto its battery base. Multiple instances of the integrated Scruzol bracket may also be provided to permit the user to store it in a variety of convenient locations.
Figure 8 illustrates the use of a Scruzol 1 stored onto a custom manufactured drill 19 according to the present invention. The stored Scruzol 1 also serves as a convenient magnetic holder for loose parts such as spare twist drill 3, spare screwdriver bit 7, screw 22 or other sundry small parts; thereby expanding the utility of both the Scruzol and the drill to which it is attached.
It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention that are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination.
