CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority from U.S. provisional application No. 61/395,350 filed 12 May 2010; entitled Pendant Button Cover. The entire contents being hereby included by reference and for which benefit of the priority date is claimed. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention is directed toward ornamentation for clothing and in particular to a button cover for garments. 
       BACKGROUND OF THE INVENTION 
       [0003]    In the prior art those wishing to dress up their dress cloths have been reticent to incorporate high value ornamentation to their covers in fear that such covers could become separated from the garment and lost. Existing button covers are generally designed as a one piece unit with a hinge joining the button and the holder. 
       SUMMARY OF THE INVENTION 
       [0004]    In accordance with the present invention, there is provided a button cover which is easy to apply and remove yet holds reliably. The button cover can be used to add bling to a button down shirt face or as a cufflink replacement on a sleeve. The cover is easy to use as one simply places the cover over a button and slides the back in place. Once the back is in proper location to hold fast to the button which is preferably sewn or otherwise attached to the garment, to opposing magnets engage to hold the cover in place to enshroud the button. It is anticipated that the movement of the back would function as a saucer hinge, however other types of hinge or backing arrangement can be envisioned which do not depart from the spirit of the present invention. 
         [0005]    It is therefore an object of the invention to provide an ornamental button cover which holds reliably, but is easy to release. 
         [0006]    It is therefore an objective of the invention to provide an ornamental button cover which can be made in different sizes. 
         [0007]    It is therefore an objective of the invention to provide an ornamental button cover which uses magnetic force a at least a portion of the latching mechanism. 
         [0008]    It is therefore an objective of the invention to provide an ornamental button cover which has a redundant latch and catch locking mechanism. 
         [0009]    It is therefore an objective of the invention to provide an ornamental button cover which can be opened and closed without the user resulting to using fingernails. 
         [0010]    It is therefore an objective of the invention to provide an ornamental button cover which is easy for those with arthritis to use. 
         [0011]    It is therefore an objective of the invention to provide an ornamental button cover in which the ornamentation is interchangeable.

     DETAILED DESCRIPTION 
       [0020]    There is generally provided a button cover ( 56 ) for ornamenting a button ( 58 ) as found on clothing as found in the embodiment of  FIG. 1 . Generally the non-claimed matter is shown in broken lines in this instant. Generally a button ( 58 ) for shirt measures about 1 cm in diameter and 3-4 mm in height. A typical button cover ( 56 ) being 2 cm in diameter and having capacity for enshrouding a button ( 58 ) into the interior. It is anticipated that the dimensions above can be scaled as desired without departing from the spirit of this invention. 
         [0021]      FIG. 2  shows a back member or fastening back ( 10 ) having a thumb latch ( 12 ) and being generally arched or curvilinear in shape and having a relief ( 14 ), preferably arched, for providing a void for the button thread or other such fastening means. A first magnet inset ( 16 ) and a second magnet inset ( 18 ) are provided for holding a first backing magnet ( 32 ) and a second backing magnet ( 34 ). The backing magnets ( 32 ) ( 34 ) being approximately 3 mm in diameter with a thickness of approximately 0.75 mm and having a magnetic strength in the order of 2900-3000 Gauss. The backing magnets ( 32 ) ( 34 ) being held in the insets ( 16 ) ( 18 ) by means of an adhesive such as epoxy or cyanoacrylate glue or the like. 
         [0022]    The fastening back ( 10 ) is made to pivot about a pin or screw, which in this instance, comprises a head ( 26 ) having a tool engagement means, a flair ( 27 ) for spreading forces, a post ( 28 ) for providing a moment of pivot, and in this preferred embodiment, a threaded portion ( 30 ) which attaches to a fastener receiver ( 52 ), which is typically threaded and held fast by means of an adhesive such as Lock Tight™ or like adhesive. A pivot hole ( 22 ) and chamfer ( 24 ) are provided for flush setting the head and providing a larger surface to minimize binding. 
         [0023]    A base ( 40 ) comprising a perimeter ( 44 ) being suited to a top ( 54 ) are firmly affixed together generally by means of a solder, welding, or gluing process. The base having a void portion ( 50 ) comprising a volume suited to encasing a button ( 58 ) is provided. The base further comprising a lip ( 43 ) preferably comprising a latch ( 42 ) opposite the fastener receiver ( 52 ) and suited to interface with a catch ( 20 ) as provided on the fastening back ( 10 ). A first magnet seat ( 46 ) and a second magnet seat ( 48 ) are disposed for holding a first base magnet ( 36 ) and a second base magnet ( 48 ) are provided. The location of the first and second base magnets ( 36 ) ( 38 ) are situated to align with the first and second backing magnets ( 32 ) ( 34 ) respectively when the fastening back ( 10 ) is pivoted or rotated into the closed position, as in  FIG. 4 . Also the base magnets ( 36 ) and ( 38 ) and the backing magnets ( 32 ) ( 34 ) are arranged such that the poles are in opposite orientation, i.e. attracting mode. Those skilled in the art can appreciate that it is anticipated that various arrangements of magnetic orientations can devised to achieve the present objective. 
         [0024]    It is also anticipated that base magnets ( 32 ) ( 34 ) of approximately 3 mm diameter by 3 mm height and comprising approximately 6,000 Gauss would be sufficient for the present purposes. It is anticipated that Neodymium material for all magnets and a stainless steel base ( 40 ) are also sufficient. 
         [0025]      FIG. 3  shows that in the open position, the void portion ( 50 ) is fully exposed allowing a button ( 58 ), not shown, to seat into the chamber.  FIG. 4  shows that with the fastening back ( 10 ) rotated into the closed position, forms a closure to enshroud the button ( 58 ) holding the ornamentation ( 56 ) and the button ( 58 ) together. It is preferred that in the closed position that the catch ( 20 ) and the latch ( 42 ) are engaged to provide an alternative or redundant point of attachment with the pin ( 28 ) head ( 26 ) combination. 
         [0026]      FIGS. 5 and 6  show a fastening back in a partially closed position. It will be noted that, as defined by the pivot head ( 26 ), magnets ( 34 ) and ( 38 ) lie in an arc defined by radius R 1  and magnets ( 32 ) and ( 36 ) lie in an arc defined by radius R 2 . As backing magnet ( 32 ) advances radially past base magnet ( 38 ) the two do not interact appreciably as they lie on different radiuses. However, as the fastening back ( 10 ) advances to the closed position, backing magnet ( 32 ) interacts with base magnet ( 36 ) substantially at the same point that backing magnet ( 34 ) interacts with base magnet ( 38 ). This multiplies the affect of the sets of magnets working in concert to hold the fastening back ( 10 ) in the closed position. 
         [0027]    In an alternate embodiment, as shown in  FIG. 7 , one or more of the base magnets ( 36 ) in this case can be advanced to cause a slight over travel of the fastening back ( 10 ). The effect being that magnet ( 32 ) will be slightly out of equilibrium with magnet ( 36 ) in this case providing a motive force for the fastening back ( 10 ) to move counter clockwise. This compelling the catch ( 20 ) to more securely engage with the latch ( 42 ), thus providing a stronger latching force between the latch ( 42 ) and the catch ( 20 ). 
       CONCLUSION, RAMIFICATIONS, AND SCOPE 
       [0028]    Although the present invention has been described in detail, those skilled in the art will understand that various changes, substitutions, and alterations herein may be made without departing from the spirit and scope of the invention in its broadest form. The invention is not considered limited to the example chosen for purposes of disclosure, and covers all changes and modifications which do not constitute departures from the true spirit and scope of this invention. 
         [0029]    For example, although the foregoing refers to magnets and in particular neodymium magnets, it is contemplated that other magnetic and ferrous materials may be used. Further, shapes and ornamentations may vary from the generally cylindrical forms for example; rectangular, polygonal or the like, and vary in terms of dimensions and exact position of structural members. Depending on the physical arrangement of the structural members such as latches, other arrangements for magnets may be used. 
         [0030]    Having thus described the invention, what is desired to be protected by Letters Patent is presented in the subsequent appended claims.
