CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation of U.S. application Ser. No. 15/078,572, filed Mar. 23, 2016 which claims priority to U.S. Provisional Application No. 62/136,944, filed Mar. 23, 2015, the entity of each is incorporated by reference herein. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    The present invention relates, in general, to magnets and clothing and, more particularly, to a magnetic harness which enables at least one metal object to be easily coupled to a vest, armband, gown, or other article of clothing and easily removed from each other. 
         [0003]    It has been proposed to provide workers with a means to attach tools while not being used or not in a resting place elsewhere in the work area. Such means have included pockets of a work garment for carrying tools, loop-shaped straps on garments or belts for retaining tools, gloves with a magnet to hold nails or small tools to the finger of the wearer, and garments with magnets permanently placed in individual pockets such that the magnets are separated from one another and not removable. Loop-shaped straps are useful only for tools of a specific range of size. Tools which exceed a certain dimension cannot be inserted in a given pocket or loop, and tools smaller than the dimension of a loop are not retained. These arrangements are also unsatisfactory in that it is relatively time-consuming to insert a tool into a pocket or the loop of a strap, and equally inconvenient to withdraw the tool. 
         [0004]    Contrary to the inherent mode of operation of pockets and straps, magnets need not be approached by the tool in any specific direction. Permanent magnets emit a magnetic field without the need for any external source of magnetism or electrical power. Temporary magnets behave as magnets while attached to or close to something that emits a magnetic field, but lose this characteristic when the source of the magnetic field is removed. Electro-magnets require electricity in order to behave as a magnet. Rare Earth magnets are magnets that are made out of the Rare Earth group of elements. The most common Rare Earth magnets are the Neodymium-Iron-Boron and Samarium Cobalt types. 
         [0005]    A metallic tool is readily secured to the magnet by merely moving it close to the magnets, and may be withdrawn from the tool holder in a similarly simple manner. The tools magnetically retained may not be dropped accidentally in the manner always possible with pockets or straps if the workman bends low so that the opening of the pocket or strap faces downward. It has now been found that the shortcomings of known tool holders arranged to be fastened to a portion of an adult body can be avoided by providing a group of magnets of which each is separated by another magnet of the group, and which jointly define an accessible engagement surface. The groups of magnets are sewn or otherwise permanently enclosed into the material of the clothing, and this has practical drawbacks; once sewn in, the magnets are difficult or impossible to remove, and therefore do not allow for a change in the magnetic field or force on the fly to accomplish holding a variety of tools. 
         [0006]    Therefore, a magnetic structure which can facilitate coupling or removal of magnetics to deal with different needs of the user is required.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0037]    As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. It is also noted that any reference to the words top, bottom, up and down, and the like, in this application refers to the alignment shown in the various drawings, as well as the normal connotations applied to such devices. 
         [0038]    A magnet is a material or object that produces a magnetic field which is a vector field that has a direction and a magnitude (also called strength). The illustrated  FIGS. 1-3  are various illustrations to explain different concepts about magnetic technology, which can be utilized in an embodiment of the present invention. 
         [0039]    Referring to  FIG. 1 , there is illustrated an exemplary block or bar magnet  10   a  which has a South pole  12  and a North pole  14  and magnetic field vectors that represent the direction and magnitude of a magnet&#39;s moment  18 . The magnet moment  18  is a vector that characterizes the overall magnetic properties of the magnet  10 . For the bar magnet  10  illustrated, the direction of the magnetic moment points  18  from the South pole  12  to the North pole  14 . The North and South poles  14 ,  12  are also referred as positive (+) and negative (−) poles or polarity, respectively. 
         [0040]    Two magnets aligned such that their polarities are the same (not shown) direction (i.e. North aligned with North) results in a repelling spatial force (not shown) which causes the two magnets to repel each other. In contrast,  FIGS. 2-3 , depicts two magnets  10   a  and  10   b  that are aligned such that their polarities are in opposite resulting in an attracting spatial force which causes the two magnets  10   a  and  10   b  to attract (stick) to each other. 
         [0041]    In  FIG. 2 , the magnets  10   a  and  10   b  are illustrated as being aligned with one another one a top the other as a single magnet  11   a , where they “stick” to each other and maintain their positions relative to each other unless a sliding force is used to disengage them. 
         [0042]      FIG. 3  illustrates the magnets  10   a  and  10   b  as being aligned with one another one side by side, where they “stick” to each other and maintain their positions relative to each other unless a sliding force is used to disengage them. The power or strength of the combined magnets  10   a ,  10   b  will increase in a ratio with which the size of the overall magnet  11   b  increases, even if the strength of the magnets  10   a ,  10   b  are different. If the two magnets are stacked together on atop the other or side by side (with opposite poles touching), as a close approximation, the magnets  10   a ,  10   b  will act like a single magnet  11   a ,  11   b  of the same overall dimension ( FIG. 2 ). This is a close approximation because the stacked or side by side magnets have slightly less magnet material in-between each other that would not be the case for a single magnet. As more and more magnets are stacked together one atop the other, they receive diminishing returns but an increase is still seen. The more magnets  10   a ,  10   b  that are stacked up (not shown), the less increase in pull force. Therefore, the better solution is to have stacks of magnets  10   a ,  10   b  in an elongate pattern, i.e. side by side, to increase the overall strength of the magnets  10   a ,  10   b , or in a way combining the illustrated patterns seen in  FIGS. 2 and 3 . 
         [0043]    It will be appreciated that  FIGS. 4-13  teach by way of example and not limitation. The number of apparatus components may be increased or decreased with respect to what is shown. In one such example, further pockets  35 , loops  36 , magnets  20 , and further magnet pockets  21  may be incorporated into an apparatus. 
         [0044]    Referring to  FIGS. 5-11 , there is illustrated a sleeveless vest or harness  1  essentially consisting of a belt  2 , an integral front portion  3 , an integral back portion  4 , two shoulder straps  6  integral with the front and back portion  3 ,  4 , and an interior magnet holding portion  7  capable of holding at least one set of magnets  20  ( FIG. 4 ). In the preferred embodiment, the harness  1  is worn on the outside of clothing, but it is foreseen that the harness  1  may be worn under clothing, as well. 
         [0045]    The belt  2  may be a single piece interwoven between the front portion  3  and the back portion  4  or it may be two separate pieces. The belt  2  may be fastened about the trunk of the wearer by means of a buckle or fastener  13 , such as a hook and loop material. The belt  2  may consist of fabric, flexible leather, or soft plastic and it will be appreciated that the exact nature of the materials of construction employed in the supporting structure is not critical. 
         [0046]    The two shoulder straps  6  define with the front and back portions  3 ,  4  an opening  8  through which the neck of a wearer normally passes. It is foreseen that the straps  6  may include have free ends (not shown), which are fixedly fastened to either the front or back portions  3 ,  4 . It is foreseen that the harness may not include a back portion  4 , wherein the straps  6  would tie or otherwise attach around the neck of a user. 
         [0047]    The harness  1  illustrated in  FIGS. 4-12  includes pockets  35  that are attached to a front outer surface  34  of the front portion  3  to hold various objects such as plastic or non-metallic parts, rubber washers, wooden objects such as pencils, or measuring devices such as rulers. It is foreseen that the pockets  35  could also be clips or clip on attachments. Pockets  35  could also be used to hold bulky items such as tape measurers, rolls of adhesive tape or a work cloth and come in various shapes and sizes. The harness  1  also includes a loop  36  that is attached to at least one of the front outer surface  34  and a back outer surface  37 . Pockets  35  and loop  36  are merely illustrative of other conventional receptacles, which the harness  1  may have in addition to the magnetic tool retaining device of the invention. 
         [0048]    Referring to  FIG. 4 , the magnet holding portion  7  includes several sets of magnets  20 , in the illustrated example, there are four sets of magnets  20  in individual re-sealable pouches, cavities, pockets  21 . It is foreseen there may be more or less pockets  21  in the present invention. It is also foreseen that the interior magnet holding portion  7  may incorporate a single re-sealable pocket (not shown), with multiple cavities to install separate arrays or magnets  22 , each cavity large enough to hold an array of magnets, as well, as a sealable layer (see  FIG. 4 ). 
         [0049]    A pocket  21  is sewn or otherwise attached to the interior of front portion  3  to situate the magnet bars  22  therein. It is foreseen that the pouches  21  may be attached by a hook and loop fastening system or some combination thereof with some being sewn, heat sealed, pressure sealed, and some being attached by hook and loop fasteners. In the preferred embodiment the pouch is located on the interior of the front portion  3 , but it is also foreseen that the pouches  21  may be located on the exterior of the front portion  3 . It is foreseen that the pockets or pouches  21  may be different heights, width, and thickness to allow for a variety of different combinations of magnets  22  in a variety of different combinations. In the illustrated example the magnet holding portion  7  further includes a water proof or resistant sealable layer  24 , wherein the aligned magnets may be enclosed in. It is foreseen that the sealable layer  24  may be removeably situated within the pocket  21  or permanently attached to the pocket  21 . The sealable layer  24  prevents the magnets  22  from moving around within the pocket  21 , and is meant to maintain the array of magnets  22  in a proper alignment 
         [0050]    Each set of magnets  20  comprises a plurality of juxtaposed (side by side) magnetic bars  22  which are positioned in the interior portion  7  of the front portion  3  inside a pouch  21 , the polarity of the magnets  20  are such that the magnetic bars  22  will attract metal on both the front face  24  and the rear face (not shown) of the magnetic bar  22 . The magnet  22  inserted is assumed to have one pole on each face, such that the direction of a pole is situated towards the at least one of front portion  3  and the back portion  4  facing inwardly and outwardly in a longitudinal direction or axis A. It is foreseen that the bottom surface  29  of the magnet bars  22  may have a hook material and a bottom interior surface of either the pocket  21  or a sealable layer  24  may have a loop material to attach the magnet to the material or vice versa. The magnet bars  22  are uniformly situated in a transverse direction B to the front and back faces and are slightly more than 1 inch distance from another set of magnets  20 . It is foreseen that the set of magnets  20  may come in different configurations, for example, a double set or a two dimensional array of magnets  20  is envisioned (not shown), wherein the set of magnets  20  extends in both directions A and B. These configurations would allow for a greater magnetic pull either across the entire array or if only needed more on a particular side, then stacking magnets  22  atop one another on the requisite side is envisioned, and the pocket  21  is envisioned to be sized and shaped to allow for this. It is foreseen that a rubber spacer (not shown) may create spaces in-between the magnets. 
         [0051]    The front face  24  of the magnet  20 , and thereby the front portion  3  is used to hold various tools  26 . Tools  26  having an approximately flat surface automatically orient themselves in such a manner that their flat surface is adjacent the maximum possible number of magnet poles. Each magnet bar  22  is identical in shape and in strength. Preferably, magnets  22  are of the rare earth 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 foreseen to use flexible magnets to replace the hard magnets. Furthermore, although magnets  22  are rectangular, magnets  22  may be round, square, or any other shape. It is foreseen that different strengths may be introduced into the set of magnets  20 . It is also foreseen that the harness can be attached to and easily slide away from a mounting surface (not shown). 
         [0052]    The array of magnets  20  being aligned cannot wrap or fold themselves about a cylindrically arcuate surface (not shown) of a retained tool  26 , but such a surface has been found to orient itself automatically in such a manner that it is engaged by more than one adjacent magnet  22 . Although the drawing shows magnetic bars  22  having sharp edges, the edges may be rounded or smoothed to facilitate the insertion. The harness  1  may consist of strong flexible fabric that will contour to the shape of the wearer. Flexible materials which are useful for the harness  1  include, but are not limited to, leather, mesh, denim, simulated leather, plastic and cloth or some combination of the like. In the illustrated example, the front and back surfaces  34 ,  37  are not made of the same material, wherein the back surface includes a mesh fabric  38 . It is foreseen that some of the material selected for the harness  1  may also be an insulative material, such as polycarbonate, for placement of the holder on a hot or electrically conductive mounting surface. Such a material would prevent the tools from getting hot and could also offer protection for the user against the heat or electrical conductivity of the environment. 
         [0053]    In accordance with another embodiment of the present invention,  FIG. 13  illustrates a chest strap  100  having a strap portion  110 , a magnetic attractive portion  120 , and straps  130  to go around a wearer&#39;s shoulder (not shown). The magnetic attractive portion  120  is defined by a plurality of magnets  140  within pockets  141  disposed in chest strap  100  in an array such that each magnet  144  is contiguous with another magnet  144 , as described above. The magnetic attractive portion  120  of chest strap  100  functions in a similar manner as the interior magnet holding portion  7  of harness  1  as described above. It is foreseen that the magnetic attractive portion  120  may be attached to the strap portion  110  by means of a hook and loop fastener, allowing the user the ability to place the magnetic means anywhere that is best suited for the task at hand. The strap portion  110  may include a pockets (not shown) and/or loop(s) (not shown) which are attached to the front outer surface  111  of the strap 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. The strap portion  110  could also include a slit (not shown) for holding such objects. In the preferred embodiment, the chest strap  100  is worn underneath clothing, but it is foreseen that the chest strap  100  may be worn on the exterior of clothing, as well. 
         [0054]    In another alternative embodiment the magnetic tool holder shown in  FIG. 14 , a magnetic wrap  200  comprises attachment means  210 , such as clamps, clips, loops or straps to allow a user to wear the device on a wrist, waist, arm, hip, thigh, chest or other body area (not shown), a strap  230 , and an interior magnetic portion  220 . The attachment means  210  of the strap  230  is illustrated as a hook and loop material arrangement for attachment of the holder to a body area (not shown). The set of magnets  240  could be in parallel along the body area (not shown), or could be in juxtaposition perpendicular to the body area. The strap  230  being made of a flexible material to conform to the contours of the body area. 
         [0055]    In accordance with another embodiment of the present invention,  FIG. 15  illustrates a gown  300  having a gown portion  310  and a magnetic attractive portion  320 . The magnetic attractive portion  320  is defined by a plurality of magnets  340  within pockets  342  disposed in an array  342  such that each magnet  344  is contiguous with another magnet  344 , as described above. The magnetic attractive portion  320  of the gown  300  functions in a similar manner as the interior magnet holding portion  7  of harness  1  as described above. The gown portion  310  may include a pockets (not shown) and/or loop(s) (not shown) which are attached to the front outer surface  311  of the gown portion  310  to hold various objects such as plastic or non-metallic parts, rubber gloves, pens, wooden objects such as pencils, or measuring devices such as rulers. In the preferred embodiment, the magnetic portion  320  is attached on the interior of the gown, but it is foreseen that the magnetic portion  320  may be attached on the exterior of clothing, as well. 
         [0056]    In accordance with another embodiment of the present invention,  FIG. 16  illustrates a necklace  400  having a chain  410  and a magnetic attractive portion  420 . The chain  410  being sized to go around the neck of a wearer. The magnetic attractive portion  420  is defined by a plurality of magnets  440  disposed in an array  442  in a pocket  441 , such that each magnet  444  is contiguous with another magnet  444 , as described above. The magnetic attractive portion  420  of necklace  400  functions in a similar manner as the interior magnet holding portion  7  of harness  1  as described above. 
         [0057]    It is foreseen that the magnetic tool holder may be other embodiments such as cottonoid holders, vests, tool belts, etc., each foreseen to be adjustable in size and fit due to a fastening system. 
         [0058]    Referring to  FIG. 17 , a method  500  of affecting the magnetic field strength of a magnet in a magnet holding garment is illustrated. At step  510 , a garment with a magnetic attractive portion is provided. The magnetic portion having an open accessible pocket with at least one magnet within the pocket. At step  520 , a metallic object or device is attached to the magnetic attractive portion of the garment. At step  530 , if the metallic device does not stick to the magnet portion, then at step  540 , the magnetic strength of the at least one magnet may be increased by the insertion of another second magnet within the accessible pocket. It is foreseen that step  540  may include adding a second magnet atop the at least one magnet or by affixing the magnets side by side. At step  550 , if the metallic device is stuck to the magnetic portion of the garment, but is determined to be difficult to remove, then at step  560 , a magnet may be removed from the pocket to adjust the overall strength of the magnets within the pocket. At step  570 , the accessible pocket is closed. It is foreseen that the strengths of first and second magnets do not need to be the same.
