This application claims priority to U.S. Provisional Application Ser. No. 61/030,955, filed Feb. 23, 2008, the contents of which is incorporated by reference herein in its entirety.
TECHNICAL FIELD OF THE INVENTIONThe present invention relates in general to the field of multi-purpose, versatile magnetic tool holders.
BACKGROUND OF THE INVENTIONIn both industrial and consumer settings there has been a growing need for a tool holder that can restrain a wide variety of tools through relying on magnetism. While present day tool holders sometimes use magnetism to supplement a separate restraint, very few are able to rely on magnetic forces alone. Those tool holders that supplement their restraints with magnetism often implement such limited forces that any resulting magnetic restraint remains incidental to the tool holder's functionality. On the other hand, those tool holders that rely purely on magnetism to perform their functions often include so much magnetism, mainly using electromagnets, that the functionality precludes tools with electronic components. Furthermore, modern tools holders that rely on magnetic restraint remain subject to a tool's ferrous properties.
Often, wrench racks provide predefined receptacles often having magnets to supplement restraining capability. While the wrench rack's magnetism is not essential to the restraint it may supplement the rack in keeping a tool in place. When such racks include magnets, such incorporation is usually inconsequential to overall functionality. Furthermore, when magnets are incorporated in such wrench racks and the like, the magnets are usually non-movable and bound to a receptacle. Tool restraints that rely purely on magnetic forces are generally usable only for certain types of tools, due to the use of electromagnets, which although powerful, can cause significant damage to electric motors incorporated in such tools. Thus, while an end user may rely on electromagnetism to hold a standard screwdriver, that user may think twice before holding an electric screwdriver by that same electromagnetic force.
As a consequence of the foregoing, a longstanding need exists for an apparatus and method allowing for the quick, simple, and effective magnetic storage and retrieval of tools whether or not a tool has magnetic properties.
SUMMARY OF THE INVENTIONIn accordance with the present invention, an apparatus and method are provided to allow for the more efficient magnetic storage and retrieval of tools. The present invention provides a magnetic tool holder that includes a tool holder's magnetic restraint and/or a restraint independent of an individual tool's ferrous properties. One embodiment of the present invention can rely on a tool's ferrous properties to provide restraint, another embodiment provides a restraint for almost any tool by relying on the magnetic attraction of the ball bearings alone or in combination with a surrounding channel.
One embodiment of the present invention is a base with one or more first recesses and one or more first magnetic ball bearings disposed within the one or more first recesses to magnetically restrain one or more tools. The base may include one or more non-magnetic ball bearings disposed within the one or more first recesses. Alternatively the base may have one or more planar faces each having one or more first recesses.
Still another embodiment of the present invention may include a base with one or more first recesses, wherein the base may have one or more apertures spaced about the one or more first recesses. Alternatively, the present invention may include a base, in which at least a portion of the base is magnetic or non-magnetic or metallic or non-metallic or elastomeric or non-elastomeric or malleable or non-malleable or ferrous or non-ferrous. Also another embodiment may have a base wherein, at least a portion of the one or first magnetic ball bearings are metallic or non-metallic or elastomeric or non-elastomeric or malleable or non-malleable or ferrous or non-ferrous. Furthermore, at least a portion of the base may be plastic or rubber.
The present invention may include a base with one or more first recesses and one or more first magnetic ball bearings disposed within the one or more first recesses to magnetically restrain one or more tools, wherein the one or more first magnetic ball bearings have differing diameters. Alternately, the one or more non-magnetic ball bearings of differing diameters may be disposed within one or more first recesses. Also the present invention may include a base, wherein the one or more first magnetic ball bearings have at least one inner core encased by a shell of an opposite polarity.

Conversely, the tool may be rendered magnetic and the material embedded or placed into a base for attachment of the tool may be ferrous.
While the bearings depicted in the figures are shown as generally spherical, the skilled artisan will recognize that the magnetic or ferrous attachment point of the present invention may have any shape, for example, linear, triangular, cubic, rectangular, polyhedral, oval, round, polygonal, as long as a contact portion is available to magnetically attract and retain a tool.
The isometric view depicts two rows one or more first magnetic ball bearings 32a, 32b, 32c, 32d, 32e, 32f substantially aligned with one row of one or more non-magnetic ball bearings 50a, 50b, 50c, 50d, 50e, 50f. This does not necessarily have to be the case in another embodiment. Any number of first magnetic ball bearings 32 may be placed anywhere about the base 20. Furthermore any number of non-magnetic ball bearings 50 may be placed anywhere about the base 20. Neither one or more first magnetic ball bearings 32a, 32b, 32c, 32d, 32e, 32f nor do one or more non-magnetic ball bearings 50a, 50b, 50c, 50d, 50e, 50f need to be placed in rows, or organized in any fashion. Accordingly, any non-magnetic ball bearing 50 could be placed next to, behind, in front of, in parallel with, adjacent to, and any number of first magnetic ball bearings 32.
Furthermore, though this particular embodiment depicts a base 20 taking a generally rectangular shape, this need not be the case. The base 20 may have any variety of shapes and any number of planes. For example, the base may take a generally trapezoidal shape, a generally ovular shape, a generally pyramid-like shape. Also, any number of first magnetic ball bearings 32 and any number of non-magnetic ball bearings 50 may be placed about any location, face, or plane of the base 20.
The top view of this particular embodiment depicts two rows one or more first magnetic ball bearings 32a, 32b, 32c, 32d, 32e, 32f substantially aligned with one row of one or more non-magnetic ball bearings 50a, 50b, 50c, 50d, 50e, 50f. This does not necessarily have to be the case in another embodiment. Any first magnetic ball bearing 32 and any non-magnetic ball bearing may be located anywhere about the base 20.
The side view in this particular embodiment depicts one or more first recesses 30a, 30b, 30c, 30d, 30e, 30f in which first magnetic ball bearings 32a, 32b, 32c, 32d, 32e, 32f are disposed. Though this particular view only depicts first magnetic ball bearings 32a, 32b, 32c, 32d, 32e, 32f, another embodiment may have non-magnetic ball bearings 50a, 50b, 50c, 50d, 50e, 50f disposed within any one or more first recesses 30a, 30b, 30c, 30d, 30e, 30f in any combination. For example non-magnetic ball bearings 50a, 50b, 50f and first magnetic ball bearings 32c, 32d, 32e may be disposed accordingly in one or more first recesses 30a, 30b, 30c, 30d, 30e, 30f.
The front view of this particular embodiment is included to show that any non-magnetic ball bearing 50 or any first magnetic ball bearing 32 may be disposed in one or more first recesses 30. Though the base 20 of this particular embodiment does not include any apertures 34, this may be the case in other embodiments.
