Description

FLEXIBLE MAGNETIC TOOL HOLDER AND METHOD OF MAKING SAME
BACKGROUND OF THE INVENTION
[0001] Users of tools in assembly or repair work, or even home and office work, often encounter a need to have easy access to and portability of tools, parts, and hardware. The flexible magnetic tool holder of the present invention is portable and can conform to various contoured mounting surfaces, including the human body.
[0002] There are several devices in the prior art which are used to hold metallic items or tools. U.S. Patent No. 361,248, entitled HOLDER FOR METAL ARTICLES, to Winton; U.S. Patent No. 2,580,099, entitled DOUBLE MAGNETIC HOLDING DEVICE, to Jaeger; U.S. Patent No. 3,204,776, entitled MAGNETIC TOOL BOARD, to Brown et al.; U.S. Patent No. 3,229,820, entitled MAGNETIC HOLDER, to Hentzi et al.; and U.S. Patent No. 4,451,810, entitled. MAGNETIC TOOL HOLDER, to Miller; all disclose the use of rigid, inflexible magnetic holders which will not conform to various contoured mounting surfaces Each device requires a permanent mounting base and each must be nailed or otherwise affixed in place. The magnets of these devices are used solely to hold the tools and are not used to mount the holder in position.
[0003] U.S. Patent No. 3,886,508, entitled MAGNETIC TOOL HOLDER, to Lavrard, discloses several garment supports for magnetic tool holders. However, the garment supports are extremely bulky, making the tool holder uncomfortable to wear. Because of these bulky supports, the tool holder cannot be easily positioned on surfaces other than a human body.
[0004] Several prior art patents disclose the use of magnets incorporated into a flexible material to protect automobile fenders. French Patent No. 1,359,867, entitled PROTEGE- ALLE MAGNETIQUE, to Mounier, discloses a curtain that is placed over a fender to protect the fender paint while the automobile is being serviced. The curtain is held in place by a series of single magnetic bars placed within one edge of the curtain. This patent does not disclose or imply using the magnetic bars to hold tools.
[0005] U.S. Patent No. 3,924,212, entitled FENDER PROTECTOR CLOTH WITH FLEXIBLE MAGNETIC STRIPS, to Brown, discloses the use of magnetic rubber strips in a fender protector. The strips are spaced at predetermined intervals on the exterior of both sides of the protector to hold the protector in place. The strips run across the entire width of the protector so that the protector can be rolled up or contoured to the shape of the automobile fender. However, this protector cannot be easily flexed across its width due to the long magnetic strips and thus the protector cannot be folded widthwise for storage or ease in portability. Another disadvantage is that this protector must be used on relatively large span, fairly flat surfaces due to its unbendable long magnetic strips. The fender protector is not capable of supporting somewhat flexible but heavier tools because its two inch spaced narrow magnetic strips are not capable of providing sufficient magnetic field strength for heavy items.
[0006] U.S. Patent No. 4,826,059, entitled MAGNETIC TOOL HOLDER, to Bosch et al. ("the Bosch tool holder"), discloses a magnetic tool holder comprising a main body, having a front face and a rear face, and an interior magnet holding portion for holding at least one set of magnets. Each set of magnets comprises a plurality of juxtaposed (side-by-side) magnetic bars which are positioned in the interior portion of the main body such that the faces of the magnetic bars will attract metal on both the front face and the rear face of the main body. With this positioning of the magnetic bar, the tool holder can be attached to and pulled away from a mounting surface and repositioned on another mounting surface. One face of the main body is mounted on a metallic surface to position the tool holder so that a user can access tools. The other face of the main body is used to hold tools. The main body is made of a flexible material such that the tool holder can be positioned on mounting surfaces having varying contours, such as an uneven or a curved surface, due to the flexible main body and the side by side positioning of the plurality of magnetic bars. [0007] However, the flexibility of the Bosch tool holder is limited due to the side-by-side positioning of the plurality of magnetic bars. Because the plurality of magnetic bars in the Bosch tool holder are positioned side-by-side, the tool holder can only flex a predetermined amount (in terms of radius of curvature) depending on the width of the magnetic bars and whether the edges of the magnetic bars are sharp or rounded. Not only is the flexibility of the Bosch tool holder limited in terms of the radius of curvature, the flexibility of the Bosch tool holder is also limited in that it is only flexible in one direction (i.e., along the edges of the side-by-side positioned magnets). For example, the tool holder may be flexed around a pipe only when the side-by-side positioned magnets are oriented parallel to the longitudinal axis of the pipe. However, if the side-by-side positioned magnets are oriented perpendicular to the longitudinal axis of the pipe, the tool holder will not flex around the pipe. This limitation prevents the Bosch tool holder from being able to conform to surfaces that are spherical, or curved or uneven in more than one direction. Additionally, the foldability of the Bosch holder is limited, in that it can only be folded at the space provided between the sets of magnets. The options available to the end user are restricted. Another shortcoming of the Bosch holder is requirement of the sets of magnets to be installed with opposing polarity, increasing the manufacturing costs. Additionally, the set of magnets is fairly large, resulting in a substantially heavy holder, thereby reducing it's ease of portability.

DETAILED DESCRIPTION OF THE INVENTION
[0021] In the description that follows, like parts are indicated throughout the specification and drawings with the same reference numerals, respectively. The figures are not drawn to scale and the proportions of certain parts have been exaggerated for convenience of illustration. [0022] One embodiment of the present invention provides a flexible magnetic tool holder for use as a tool and parts holder which can be positioned on magnetically attractable mounting surfaces having varying contours. The flexible magnetic tool holder can be used by mechanics, plumbers, oil drillers, or the like, to hold tools, such as screwdrivers, pliers, or wrenches; by office workers for office tools such as scissors and letter openers; by dentists and doctors for holding the tools of their trade; restaurant or household workers for tools, i.e. kitchen or garden; and by sports enthusiasts, including underwater activities such as holding scuba diving tools. .The use of the word "tool" throughout the specification and claims includes any metallic object. Such objects can include hand-held tools, industrial tools, parts, and hardware (nails, nuts, bolts, paperclips, and the like). The use of the term "metal" or "metallic" throughout the specification and claims means any material, metal or alloy which is attracted to a magnet.
[0023] Referring to FIGS. 1-3, a flexible magnetic tool holder 10 according to one embodiment of the present invention is illustrated. Tool holder 10 is substantially flat and includes a first layer 20 having a inner surface 22 and an outer surface 24 and a second layer 30 having an inner surface 32 and an outer surface 34. Alternatively, one skilled in the art would recognize that a single sheet of material may be used and folded in half to create two layers. In the case where a single sheet of material is used, the single sheet of material exhibits a hypothetical longitudinal, line that divides the sheet of material into a first layer and a second layer when the sheet of material is folded along the longitudinal hypothetical line. Once the sheet of material is folded, the inner surface of the first layer is facing the inner surface of the second layer.
[0024] Both first and second layers 20, 30 are made from a flexible material such as PVC sheet material that is 0.1 mm thick. Although it is preferable to use PVC sheet tool material as the flexible material for first and second layers 20, 30, other materials may be used such as leather, neoprene, cloth, or other flexible plastic materials. Also, although it is preferable that the PVC sheet material is 0.1 mm thick, other thicknesses may be used depending-on the application.
[0025] Disposed between the inner surfaces 22, 32 of first and second layers 20, 30 are a plurality of thin, square magnets 40 such that the faces of magnets 40 will attract metal on both the outer surfaces 24, 34 of first and second layers 20, 30. Magnets 40 are arranged in a staggered array as shown in FIG. 2A such that no magnet 40 is contiguous with another magnet 40 leaving a predetermined space Ly between adjacent magnets 40 in the y-direction and a predetermined space Lx between adjacent magnets 40 in the x-direction (i.e., perpendicular to the y-direction). Alternatively, magnets 40 may be arranged in a linear array as shown in FIG. 2B such that no magnet is contiguous with another magnet leaving a predetermined space Ly between adjacent magnets 40 in the y-direction and a predetermined space Lx between adjacent magnets 40 in the x-direction. Furthermore, the arrangement of magnets 40 is not limited to the arrays illustrated in FIGS. 2A and 2B; thus, magnets 40 may be arranged in any pattern so long as magnets 40 are not contiguous with each other.
[0026] Arranging magnets 40 in an array such that a predetermined space is present, between adjacent magnets 40 in the x and y directions permits tool holder 10 to be flexible any combination of directions, including curvilinear, thereby allowing tool holder 10 to conform to surfaces having various contours such as flat surfaces, curved surfaces (e.g., convex or concave), spherical surfaces (e.g., convex or concave), and uneven surfaces (e.g., dimpled, wavy, or stepped). Also, the spacing between magnets 40 allows tool holder 10 to be flexed at a tighter radius of curvature than the prior art magnetic tool holders. Further, the spacing between adjacent magnets 40 permits tool holder 10 to be foldable along multiple axes wherein each axis is located between adjacent magnets 40 as shown in FIGS. 2A and 2B (see axes At, A2, and A3). Another advantage created by the spacing between adjacent magnets is that the weight of tool holder 10 is reduced compared to prior art tool holder having magnets positioned side-by-side one another.
[0027] Preferably, magnets 40 are of the hard, permanent type such as Neodymium Iron Boron (NdFeB) magnets, but other types of hard magnets may be used alone or in combination with NdFeB magnets such as Samarium Cobalt (SmCo), Aluminum Nickel Cobalt (AlNiCo), Ferrite, or Ferrite/Ceramic magnets. Also, it is possible to use flexible magnets to replace the hard magnets. Furthermore, although magnets 40 are square, magnets 40 may be round, rectangular, or any other shape.
[0028] Preferably, magnets 40 have a single pole on each pole surface, but it is possible to utilize magnets 40 having multiple poles on each pole surface alone or in combination with magnets 40 having a single pole on each pole surface. Optionally, magnets 40 may be randomly oriented between first and second layers 20, 30 with respect to polarity. For example, assuming that magnets 40 having a single pole on each pole surface are utilized, the "north" face of some magnets 40 may face first layer 20, while the "south" face of other magnets may also face first layer 20.
[0029] The ability to flex tool holder 10 along multiple axes permits tool holder 10 to be bent and shaped as desired by a user. For example, tool holder 10 can be mounted on surfaces having varying contours, such as an uneven or a curved surface (e.g., convex or concave), due to the flexibility of first and second layers 20, 30 and the spaces between magnets 40.
[0030] Because magnets 40 are arranged such that the faces of magnets 40 will attract metal on both the outer surfaces 24, 34 of first and second layers 20, 30, tool holder 10 can be attached to and easily pulled away from a mounting surface and repositioned on another mounting surface. Outer surface 24 of tool holder 10 may be mounted on a metallic surface to position tool holder 10 so that a user can access tools. Consequently, outer surface 34 of tool holder 10 is then used to hold tools. For example, if the outer surface 24 of tool holder 10 is attached to an automobile hood, then the outer surface 34 of tool holder 10 can be used to hold tools.
[0031] To prevent magnets 40 from moving around between first and second layers 20, 30 thereby maintaining magnets 40 in its particular array, first and second layers 20, 30 are heat sealed around each magnet 40 forming a heat seal ring 42 (or other shape) around each magnet 40 as shown in FIG. 2A. Other possible methods to keep magnets 40 in place is to stitch around each magnet 24 forming a stitching ring (or other shape) or glue each magnet 40 to either or both inner surfaces 22, 32 using an epoxy or other adhesive.
[0032] The peripheral edges of first and second layers 20, 30 may be heat sealed or sonic welded together thereby forming edge seams 50 to prevent first and second layers 20, 30 from separating apart. Optionally, first and second layers 20, 30 may be stitched together along peripheral edges to form edge seams 50. Alternatively, first and second layers 20, 30 may be glued together along the peripheral edges of tool holder 10 using an epoxy or other adhesive. Further, first and second layers 20, 30 may be heat sealed together across the length of tool holder 10 to form seams 52 as shown in FIG. 2A. Seams 52 may serve as a guide for folding tool holder 10 in a similar fashion as folding a letter. Of course, those skilled in the art will recognize that seams 52 can be spaced apart at any distance desirable for serving as guides for folding tool holder 10.
[0033] Tool holder 10 further includes two hollow grommets 54 to permit the user to hang tool holder 10 on hooks, pegs, or the like. Optionally, tool holder 10 may be provided with two openings that extend through both first and second layers 20, 30 to permit the user to hang tool holder 10 on hooks, pegs, or the like. Although tool holder 10 includes two hollow grommets 54 to permit the user to hang tool holder 10, one skilled in the art would recognize that less than two or more than two hollow grommets 54 may be provided.
[0034] Referring to FIGS. 4-6, a magnetic tool holder 10 according to another embodiment of the present invention is illustrated. Tool holder 10' is similar to tool holder 10, yet further comprises a flexible jacket 58 that includes a third layer 60 having an inner surface 62 and an outer surface 64 and a fourth layer 70 having an inner surface 72 and an outer surface 74 to protect the outer surfaces 24, 34 of first and second layers 20, 30. Alternatively, one skilled in the art would recognize that a single sheet of material may be used and folded in half to create two layers. In the case where a single sheet of material is used, the single sheet of material exhibits a hypothetical longitudinal line that divides the sheet of material into a first layer and a second layer when the sheet of material is folded along the longitudinal hypothetical line. Once the sheet of material is folded, the inner surface of the first layer is facing the inner surface of the second layer.
[0035] In this embodiment, first and second layers 20, 30 with magnets 40 disposed therebetween are provided between third and fourth layers 60, 70. Both third and fourth layers 60, 70 are made from a flexible tool material such as PVC sheet tool material that is 0.8 mm thick. The increased thickness of third and fourth layers provides extra protection against magnet damage to magnets 40. Although it is preferable to use PVC sheet tool material as the flexible tool material for third and fourth layers 30, 36, other tool materials may be used such as leather, neoprene, cloth, or other flexible plastic tool materials. Also, although it is preferable that the PVC sheet tool material is 0.8 mm thick, other thicknesses may be used depending on the application. [0036] To couple third layer 60 to fourth layer 70, third layer 60 and fourth layer 70 are heat sealed together (either alone or in combination with first and second layers 20, 30) along the peripheral edges of third and fourth layers 60, 70 to form edge seams 50 and across the length of flexible jacket 58 to form seams 52 as shown in FIG. 5. The edge seams 50 formed along the peripheral edges prevent third and fourth layers 60, 70 from separating apart at the edges. The coupling of third and fourth layers 60, 70 to first and second layers 20, 30 through seams 52 serve to strengthen tool holder 10' and prevent first and second layers 20, 30 from bunching up between third and fourth layers 60, 70. Optionally, third and fourth layers 30, 36 and first and second layers 20, 30 may be stitched together along peripheral edges of flexible jacket 58 to form edge seams 50 and across the length of flexible jacket 55 to form seams 52. Another possible method is to glue third and fourth layers 60, 70 together the peripheral edges of tool holder 10 using an epoxy or other adhesive.
[0037] Tool holder 10' further includes two hollow grommets 54 to permit the user to hang tool holder 10' on hooks, pegs, or the like. Optionally, tool holder 10' may be provided with two openings that extend through first, second, third, and fourth layers 20, 30, 60, 70 to permit the user to hang tool holder 10' on hooks, pegs, or the like. Although tool holder 10' includes two hollow grommets 54 to permit the user to hang tool holder 10', one skilled in the art would recognize that less than two or more than two hollow grommets 54 may be provided.
[0038] Although the figures depict tool holders 10 and 10' as rectangular in shape, it is possible to form tool holders 10 and 10' in any geometric shape such as circular, triangular, pentagonal, hexagonal, octagonal, or any other shape. Optionally, the tool holder may be formed in the shape of a company's logo or trademark.
[0039] With respect to FIG. 7, an assembled view of magnetic tool holder 10 is illustrated. Tools 90 may be placed on tool holder 10 so that tools 90 are not easily disturbed from the location. Tools 90 are held to the tool holder 10 by magnetic attracting forces emanating from outer surface 24 of first layer 20. If tool holder 10 is placed on a magnetic surface, then tool holder 10 is held to the magnetic surface by magnetic attracting forces emanating from outer surface 34 of second layer 30. Tool holder 10 is also useful in keeping nuts 92 and bolts 94 from rolling away from the work area defined by tool holder 10. In some instances, tool holder 10 is placed on a flat, horizontal surface, h contrast, tool holder 10 may be placed on a vertical, magnetic surface such as a cabinet or the like. Tools 90 may be attracted to tool holder 10 on a vertical surface similar to the attraction between tools 90 and tool holder 10 on a horizontal surface.
[0040] With respect to FIG. 8, a view of magnetic tool holder 10 attached to a nonplanar surface 96 (e.g., curved surface) is shown. Because tool holder 10 is flexible and includes spaces between each magnet 40, the surface on which tool holder 10 rests does not need to be planar. Tool holder 10 is magnetically attracted to the nonplanar surface 96 and further attracts magnetizable tools 90 to tool holder 10. Tool holder 10 may be used, for example, when a mechanic is working under a hood and needs a plurality of tools 90 at his disposal. The mechanic may attach the tools 90 to tool holder 10 so that he does not have to travel to and from a tool bench whenever a different tool is needed.
[0041] In another embodiment, tool holder 10 may include a lip or ledge at the bottom of tool holder 10 to catch or hold anything that may accidentally slide off tool holder 10. Alternatively, a pouch or pocket may be provided on tool holder 10 to serve as a safety feature in case tools accidentally slide off of tool holder 10. The pouches may be made of a netting material or translucent plastic material so that the user can see the tools that fell into the pouches or pockets.
[0042] In yet another embodiment, a removable, washable cover or lining may be provided for tool holder 10 to maintain the cleanliness of tool holder 10 including the removal of metal shavings from tool holder 10. If provided, a user may remove the cover and wash or shake the cover to remove dirt, metal shavings, and/or debris.
[0043] Although the embodiments discussed above refer to only tool holder 10, it is obvious that tool holder 10' may be used and modified in similar fashions as tool holder 10.
[0044] In accordance with another embodiment of the present invention, FIG. 9 illustrates an apron 100 having an apron portion 110, a magnetic attractive portion 120, and straps 130 to be tied around a user's waist. The magnetic attractive portion 120 is defined by a plurality of magnets 140 disposed in apron 100 (between the two layers of tool material that comprise apron 100) in an array such that no magnet 140 is contiguous with another magnet 140. Alternatively, magnets 140 may be provided in a flexible tool holder, similar to the ones described above (tool holder 10, 10' shown in FIGS. 1-6) that is disposed on apron 100 (front or rear outer surface) or between the layers comprising apron 100. The magnetic attractive portion 120 of apron 100 functions in a similar manner as the flexible magnetic tool holder 10, 10' as described above. The apron portion 110 may include a pocket 150 and/or loop(s) 160 which are attached to the front outer surface of the apron portion 110 to hold various objects such as plastic or non- metallic parts, rubber washers, wooden objects such as pencils, or measuring devices such as rulers. Pocket 150 could also be used to hold bulky items such as tape measurers, rolls of adhesive tape or a work cloth. The apron portion 110 could also include a slit (not shown) for holding such objects.
[0045] In accordance with another embodiment of the present invention, FIG. 10 illustrates a wristband 200 comprising a strap 205, a ring 210, a magnetic attractive portion 220, and a hook 225a and loop 225b arrangement for attachment to a user's wrist. The magnetic attractive portion 220 is defined by a plurality of magnets 240 disposed in wristband 200 (between the two layers of tool material that comprise wristband 200) in an array such that no magnet 240 is contiguous with another magnet 240. Alternatively, magnets 240 may be provided in a flexible tool holder, similar to the ones described above (i.e., tool holders 10, 10' shown in FIGS. 1-6) that is disposed on wristband 200 (front or rear outer surface) or between the layers comprising wristband 200. The magnetic attractive portion 220 of wristband 200 functions in a similar manner as the flexible magnetic tool holder 10, 10' as described above.
[0046] In accordance with another embodiment of the present invention, FIG. 11 illustrates a vest 300 having vest portion 310 and a magnetic attractive portion 320 defined by a plurality of magnets 340 disposed in vest 300 (between the two layers of tool material that comprise vest 300) in an array such that no magnet 340 is contiguous with another magnet 340. Alternatively, magnets 340 may be provided in a flexible tool holder, similar to the ones described above (tool holder 10,10' shown in FIGS. 1-6) that is disposed on vest 300 (front or rear outer surface) or between the layers comprising vest 300. The magnetic attractive portion 320 of vest 300 functions in a similar manner as the flexible magnetic tool holder 10, 10' as described above. The vest portion 310 may include a pocket 350 that is attached to the front outer surface of the vest portion 310 to hold various objects such as plastic or non-metallic parts, rubber washers, wooden objects such as pencils, or measuring devices such as rulers. Pocket 350 could also be used to hold bulky items such as tape measurers, rolls of adhesive tape or a work cloth.
[0047] Although the invention has been described with reference to the preferred embodiments, it will be apparent to one skilled in the art that variations and modifications are contemplated within the spirit and scope of the invention. The drawings and description of the preferred embodiments are made by way of example rather than to limit the scope of the invention, and it is intended to cover within the spirit and scope of the invention all such changes and modifications.
