(7) Reference will now be made in detail to the present preferred embodiments of the magnetic parts holder and tailgate assembly, examples of which are illustrated in the accompanying drawing figures.

DETAILED DESCRIPTION

(8) Reference is now made to FIG. 1 illustrating a pickup truck 10 including a cargo bed 12 and a tailgate assembly 14.

(9) Reference is now made to FIG. 2 which is a detailed perspective view of the tailgate 14 and, more specifically, the inner face or wall 16 of the tailgate incorporating or including a magnetic parts holder generally designated reference numeral 18. As illustrated in FIGS. 2-4, the magnetic parts holder 18 comprises the inner tailgate body panel 20 which includes a cavity/opening 22. A non-ferromagnetic cover or access panel 24 closes the cavity and may, for example, be secured in place by means of a plurality of fasteners such as screws 26. One or more magnetic elements 28 are carried on a back side 30 of the access panel or cover 24. Each magnetic element 28 may take the form of a thin sheet of magnetic material so as to require very little space within the cavity/opening 20 thereby leaving that space available for other components such as, for example, a cargo bed entry assist ladder of the type disclosed in published U.S. Patent Application 2014/0203587 (not shown).

(10) In the embodiment illustrated in FIG. 3, three magnetic elements 28 are provided. One of the magnetic elements 28 is secured to the backside or rear face 30 of the access panel 24 by means of an adhesive 32 (see also FIG. 4). The other two magnetic elements 28 are secured in place by means of a fastener such as the illustrated rivet 34 (see FIG. 5).

(11) As illustrated, the access cover 24 includes one or more recesses 36, 38 of varying shape. Recesses 36 are circular in shape and they may be a part of a broader or larger recess of oval shape 38. As illustrated, the magnetic elements 28 may correspond in size and shape to the overlying recess (note the circular magnetic elements 28 under the circular recesses 36 at the left side of FIG. 3 and note FIGS. 4 and 5) or they may extend substantially across the entire recess (note the magnetic element 28 at the right side of FIG. 3 extending across the oval recess 38).

(12) In any embodiment, the access cover 24 is preferably made from a non-ferromagnetic material. In one possible embodiment, the access cover is made from a paramagnetic material. In one particularly useful embodiment, the access cover 24 is made from aluminum or an aluminum alloy. While a ferromagnetic material would serve to disperse the magnetic field of the magnetic element 28 throughout the ferromagnetic material of the tailgate so that no part holding quality would exist, non-ferromagnetic/paramagnetic materials such as aluminum and aluminum alloy allow the magnetic field to pass relatively freely through the cover with the strength necessary to positively hold parts such as the nuts and bolts 40 in the recess 36 at a convenient and easily accessible location. This positive force is typically sufficient to prevent screws or other ferromagnetic parts from rolling away and being lost when inadvertently bumped or disturbed.

(13) When a ferromagnetic rivet 34 is used to secure the magnetic element 28 to the non-ferromagnetic/paramagnetic access cover 24, that rivet extends through both the magnetic element and the cover. The exposed portion of the rivet 34 at the outer surface of the cover 24 acts as a concentration point for the magnetic field of the magnetic element 28 providing an even higher force to hold a ferromagnetic object 40 in place on the surface of the cover.

(14) It should also be appreciated that a method of providing a tailgate 14 with a magnetic parts holder 18 is disclosed. That method may be broadly described as comprising the steps of providing the tailgate 14 with an access cover 24 of paramagnetic material and mounting a magnetic element 28 inside the tailgate 14 against the access cover. Further, the method may include providing the access cover 24 with a recess 36, 38 overlying the magnetic element 28.

(15) Still further, the method may be described as further including the step of fastening the magnetic element 28 to the access cover 24 by means of an adhesive 32 or a fastener such as a rivet 34. Still further, the method may include using a magnetic element 28 sized and shaped to correspond to the overlying recess 36, 38 if desired.

(16) In summary, numerous benefits result when employing the concepts disclosed in this document. The tailgate assembly 14 incorporates a magnetic parts holder 18 on an inner surface thereof that rest substantially horizontal when the tailgate is open. The combination of the recesses 36, 38 and cooperating underlying magnetic elements 28 ensure that small ferromagnetic parts such as nuts, bolts, screws and washers 40 are positively held in place in the recess at a location that may be conveniently accessed when one wishes to retrieve a nut, bolt, screw or washer and use it to complete the task at hand. Advantageously, the positive holding force provided by the magnetic element 28 through the access cover 24 of non-ferromagnetic material aids in preventing small ferromagnetic parts such as nuts, bolts, screws and washers 40 from being inadvertently lost while working. Accordingly, the tailgate assembly 14, as set forth and described in this document, provides a significant advantage and represents an advance in the art.

(17) The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
