CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/604,215, filed Feb. 28, 2012, entitled “Magnetic Locking Device for Attaching an Auxiliary Item to a Pull-handle Wheeled Luggage Case” which is hereby incorporated by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates, in general, to a magnetic locking device system for attaching an auxiliary item to a pull-handle wheeled bag or other item. 
       BACKGROUND OF THE INVENTION 
       [0003]    It is common practice among travelers to carry more than one piece of luggage generally one large piece (referred to herein as “wheeled luggage”) and a smaller auxiliary piece of luggage (referred to herein as an “auxiliary item” or “bag”). This invention could also be used to connect together any two items if one has a pull-handle and wheels. This auxiliary item could be, for example, a cosmetic bag, overnight bag, messenger bag or brief case. Generally the traveler places this auxiliary item on the wheeled luggage case by seating it on top of the case and sometimes strapping it to the extended handle. With this arrangement, especially with a single tube handle, rapid movement and turning of the wheeled luggage case can cause the auxiliary item to slide or twist away from its desired position on the wheeled luggage. It is cumbersome and time consuming to fasten and undo the strap attached to the handle. Further, the bag is not securely attached and can be easily stolen by a passerby. 
         [0004]    Devices allowing two pieces of luggage to be attached to one another have been around for decades however none solve the problems with the auxiliary item sliding or twisting away from its desired position or being cumbersome and time consuming to attach and detach. With current devices which attach the auxiliary item to the pull-handle or a telescoping handle of the wheeled luggage, rapid movements and quick turns of the traveler cause the auxiliary item to slide off the top of the wheeled luggage. In this description the wheeled luggage has a pull-handle, this pull-handle can either have a single tube arrangement or multiple tubes, a multi-tube pull-handle will be referred to as a telescoping handle. The instant invention can function with either a single tube pull-handle or a multi-tube telescoping handle. 
         [0005]    Inventions that modify auxiliary bags to solve the problem of sliding generally include a strap or pocket on the back side of the auxiliary bag. This strap is placed over the telescoping pull-handle of a wheeled luggage case in order to secure the auxiliary bag on top of the luggage. The problem with these systems is that the auxiliary bag can be very difficult to place over the telescoping pull-handle and the user generally has to use two hands with this operation. Auxiliary bags with straps also tend to slide off of the center of the wheeled luggage bag or other item creating both inconvenience and loss of time for the traveler. Even this method does not solve the problem of potential theft. 
         [0006]    Other inventions such as support bars fixed on the telescoping luggage handle or the wheeled luggage case itself attempt to solve the problem of preventing the auxiliary bag from twisting during travel. These inventions also do not provide significant added value to the user as they often require the user to activate additional parts on the telescoping pull-handle or wheeled luggage case apart from the telescoping pull-handle (such as supporting arms). These systems require more time from the user to set the auxiliary bag properly on the wheeled luggage case. Besides the loss of time in activating the supporting structures, additional supports often become intangled with the auxiliary bag&#39;s support strap or carrying straps, adding to the user&#39;s inconvenience. 
         [0007]    There is, thus, a need for a magnetic locking device system and method to allow users to easily attach and detach auxiliary items to a pull-handle and item with wheels. This invention will prevent auxiliary items from twisting or falling off of the wheeled item when locked into place, is very user friendly, and assists in preventing theft of the auxiliary bag. 
       SUMMARY OF THE INVENTION 
       [0008]    This invention involves a method for manufacturing and using a magnetic locking device system for attaching an auxiliary item to a pull-handle or other telescoping tubular device of a wheeled bag or other wheeled item. This system allows two bags to easily be secured together, quickly and efficiently while a user is on the go. 
         [0009]    The object of the present invention is to provide a device for attaching two items together securely so that the auxiliary item does not move or shift and is securely snapped to the wheeled item. In a preferred embodiment this invention would be used by a traveler with two bags, wherein one bag is a wheeled piece of luggage and the other is a second bag also referred to as an auxiliary item. This device allows the two bags to be attached and detached from one another quickly thus eliminating defects and drawbacks encountered in the prior art. The magnetic locking device system includes a wheeled piece of luggage with a pull-handle, one or more auxiliary bags, a magnetic locking pin located inside a luggage pull-handle tube controlled by an operating button, a locking pin hole on the handle, a mount located on the exterior surface of the pull-handle on top of the pin hole, and an auxiliary item attachment adaptor attached to at least one surface of a second bag. 
         [0010]    The system is used when a traveler snaps the second bag&#39;s auxiliary item attachment adaptor into the mount on the pull-handle of the wheeled luggage thus effectively attaching the two pieces together. If the traveler wishes to remove the second bag from the wheeled luggage, they merely need to depress the release button on the pull-handle thus removing the magnetic force which connects the two bags together through the connection with the locking pin, mount and auxiliary attachment adaptor. 
         [0011]    Although there are other systems for attaching auxiliary items to wheeled luggage this magnetic locking device is unique in that it allows the auxiliary bag to be rapidly attached to the wheeled luggage, the attachment of the two bags can be done with one hand, the auxiliary bag will not fall off the wheeled luggage once it is snapped in place, the auxiliary item can be quickly removed from the wheeled luggage, the operating button of the pull-handle controls both the refraction of the pull-handle and also the locking and unlocking of the mount (which is explained in detail below) on the wheeled luggage to the auxiliary item attachment. In this system the pull-handle and attached mount can be fully retracted into the wheeled bag and stored in the bag when the handle is in its down position.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0036]    After reading this description it will become apparent to one skilled in the art how to implement the invention in various alternative embodiments and alternative applications. However, all the various embodiments of the present invention will not be described herein. It is understood that the embodiments presented here are presented by way of an example only, and not limitation. As such, this detailed description of various alternative embodiments should not be construed to limit the scope or breadth of the present invention as set forth below. 
         [0037]    The magnetic locking device is a system which allows two pieces of luggage or other items to be securely attached together, quickly and easily when a person is traveling. It should be understood that this invention can be used with any item which has wheels and a pull-handle, however for the ease of description herein the preferred embodiment of two pieces of luggage shall be described below. The magnetic locking device includes a magnetic locking pin controlled by an operating button located in the pull-handle of an item of wheeled luggage, a magnetic locking pin hole which allows the locking pin to extrude from the handle or retract into the handle when the operating button is pressed, and an attachment mount located on the exterior surface of the pull-handle which can retract into the wheeled luggage with the handle and that connects and snaps into a auxiliary item attachment adaptor connected to the outside of a second bag. The magnetic locking device system is used by placing a second bag or auxiliary piece of luggage on top of a wheeled luggage bag with a mount on the outside of the handle and snapping the attachment adaptor to the auxiliary piece of the luggage. It is very easy to release the auxiliary item from the wheeled luggage by easily depressing the operating buttons located on the telescoping pull-handle; based on this, it enables a traveler to easily snap together two pieces of luggage on the go and release them quickly to take them a part. The following is a detailed description of the magnetic locking device system and the method of using the same. 
         [0038]    With reference to  FIG. 1 , a wheeled piece of luggage  12  is seen with the pull-handle  14  being extended and an auxiliary item mount  24  attached to the exterior surface of the pull-handle  14 . The extended position is the position the handle  14  would be in when an auxiliary item  42  is connected to the wheeled luggage  12 . Auxiliary item mount  24  quickly snaps into the auxiliary item attachment adaptor  44  ( FIG. 3 ) located on a second bag  42 . The auxiliary item mount  24  and auxiliary item attachment adaptor  44  need to be the same shape so that they can connect together, if the attachment adaptor  44  is of a different shape it can be modified to fit the auxiliary item mount  24  by the use of a form adaptor  46  ( FIG. 12A ).  FIG. 2  shows the outside of the wheeled luggage with a locking pin hole which will be described below. The auxiliary item mount sits on top of the locking pin hole  20 . The pull-handle  14  is comprised of one or more tubes  15 , a locking pin  16  with internal mechanism for control (one embodiment described below), a locking pin hole  20 , and an operating button  18  which controls the extension and retraction of the locking pin. A pull-handle  14  with multiple tubes  15  is referred to as a telescoping pull-handle. 
         [0039]      FIG. 1  shows one embodiment of an auxiliary item mount  24  on a telescoping pull-handle  14  of a wheeled luggage case  12 . The auxiliary item mount  24  may be constructed individually and fixed to the pull-handle  14  or be formed as a single piece with the pull-handle  14 . The auxiliary item mount  24  is shown in a rectangular shape however it may also be constructed in different shapes in order to be compatible with different auxiliary item attachment adaptors  44  (explained below). The auxiliary item mount  24  can also be constructed from a variety of materials such as plastic or metal among others. 
         [0040]    The telescoping pull-handle  14  is raised and lowered using the operating button  18 , which in this embodiment sits on top of the handle. The operating button  18  when depressed causes the locking pin to retract which releases the auxiliary attachment adaptor  44  from the auxiliary item mount  24  and allows the second bag  42  to be removed ( FIGS. 10A and 10B ) and the handle  14  and auxiliary item mount  24  to be retracted into the wheeled luggage case  12 . In the embodiment shown in  FIG. 1 , the locking pin hole  20  is located on the front of the telescope tube  15 , it allows for an internal magnetic locking pin  16  (as shown in  FIG. 5B ) to lock the telescoping tubes  15  in order to prevent the telescoping pull-handle from being lowered.  FIG. 3  shows an auxiliary item  42  with an attached auxiliary attachment adaptor  44  on the lower backside. 
         [0041]      FIG. 4A-4C  shows the functionality and components of a telescoping pull-handle  14 .  FIG. 4A  shows a front view of a multi-tube telescoping pull-handle  14 , it has three tubes which retract into one another and ultimately into the wheeled bag  12 . The interlocking pin hole  20  is located on the telescoping tubes  15 .  FIG. 4B  shows a side view of the telescoping pull-handle  14  shown in a locked position. Here the magnetic locking pin  16  extrudes from the telescoping tube  15 , in this position, the user is unable to retract a pull-handle  14  into the wheeled luggage case  12  as it is locked in position ready to have an auxiliary item attached. 
         [0042]      FIG. 4C  is a side view of one embodiment of a telescoping pull-handle  14  shown in the unlocked position. When the user presses operating button  18  on the pull-handle  14 , the magnetic locking pins  16  are retracted inside telescoping tubes  15 . In this position, the user is able to lower the telescoping pull-handle  14  into the wheeled luggage case  12  and release an auxiliary bag  42  if one is attached to the mount  24  ( FIG. 1 ) (not shown here). 
         [0043]      FIG. 5A  shows one embodiment of a magnetic locking pin  16 , which is a key component of the instant invention. The magnetic locking pin  16  is constructed with a magnetic locking pin tip  17  that can extrude from the telescoping tube  15  when it is in the locked position (as seen in  FIG. 2B ) or retract inside of the telescoping tube  15  when it is in the unlocked position by the means of the operating button  18  (as seen in  FIG. 2C ). In the embodiment of the locking pin shown here the locking pin  16  includes a spring  21 , locking pin base  23 , and magnetic locking pin tip  16 . In this embodiment, the magnetic locking pin tip  16  has been threaded and screwed inside of the locking pin base  23 . Numerous embodiments of the magnetic locking pin  16  are possible so that it is compatible with different internal mechanisms of the telescoping pull-handle  14 . Other examples would be constructing the magnetic locking pin tip  16  and locking pin base  23  as a single piece or using glue or adhesives to attach the magnetic locking pin  16  to the locking pin base  23 . Both the magnetic locking pin  16  and locking pin base  23  can also be constructed with a variety of materials (aluminum, steel, iron, titanium, plastic, resin, so long as the magnetic locking pin tip  16  is magnetic) and be made in different shapes and sizes. The magnetic locking pin  16  may be joined to the magnetic locking pin tip  17  by a number of means, including but not limited to fusing, gluing welding, and soldering; in the alternative the magnetic locking pin  16  and magnetic locking pin tip  17  can be constructed as one single place. 
         [0044]      FIG. 6  shows one embodiment of how the auxiliary item mount  24  can be fixed on the tube  15  of a pull-handle  14 . With each embodiment, the auxiliary item mount  24  must be positioned on top of the locking pin hole  20  in order to allow for the magnetic connection between the locking switch  30  and the magnetic locking pin  16  (explained below). In this embodiment, the tube  15  is made with auxiliary item mount studs  28  that the auxiliary item mount  24  can be screwed into. Other embodiments for fixing the auxiliary item mount  24  to the telescoping tube  15  include welding, soldering, gluing, and adhesives among others. The auxiliary item mount can also be constructed in a way that it fully surrounds the tube  15  so that it can be clamped in place. 
         [0045]      FIG. 7  is a side view of one embodiment of the auxiliary item mount  24  on the tube  15 . The locking switch  30  is shown in the locked position. The auxiliary item mount  24  covers the locking pin hole  20  (shown in  FIG. 2 ) on the pull-handle  14 . In the embodiment shown in  FIG. 7 , the mount  24  is attached via four screws to the tube  15 . 
         [0046]      FIG. 8  shows one embodiment of how the auxiliary item mount  24  can be constructed. A switch magnet  32  is attached to a locking switch  30  via a switch magnet mount  34 . The locking switch  30  and switch magnet mount  34  can also be constructed as a single piece. The locking switch  30  is then attached inside of an auxiliary item mount frame  26  using a hinge  36 . The locking switch  30  may be attached to the inside of the auxiliary item mount frame  26  by a number of means so long as the locking switch  30  is able to pivot forward and backward inside of the auxiliary item mount frame  26 . 
         [0047]      FIG. 9A  is a cross-sectional view of the auxiliary item mount  24  attached to the pull-handle  14 . The locking pin  16  is shown in the tube  15  of the pull-handle  14 . The auxiliary item mount  24  is shown in the locked position. Here, the magnetic locking pin  16  extrudes through the locking pin hole  20  because of the outward pressure exerted on the magnetic locking pin  16  by the spring  21 . In this position, the magnetic locking pin  16  magnetically connects to the switch magnet  32  and pushes the attached locking switch  30  outside of the auxiliary item mount frame  26 . If an auxiliary bag  42  with auxiliary item attachment adaptor  44  (shown in  FIGS. 10A and 10B ) was rested on top of the auxiliary item mount  24  at this stage, it would be locked into place as the locking switch  30  would engage with the auxiliary item attachment adaptor  44 . 
         [0048]    The extruding and retracting movement of magnetic locking pin  16  is controlled by the operating button  18  on top of the telescoping pull-handle  14 . There are various internal mechanisms for controlling the extruding and retracting movement of the magnetic locking pin  16  itself and this mechanism is out of the scope of the present invention. However, in some embodiments this movement is controlled by a retraction controller  40 , retraction controller shaft  41  and internal control rod  19  as shown in  FIGS. 9A and 9B . When the user presses the operating button  18 , downward pressure is exerted on the retraction controller shaft  41  by means of the internal control rod  19 . As the internal control rod  19  is depressed, the reaction controller shaft  41  makes contact with the magnetic locking pin  16  and pushes the magnetic locking pin tip  17  inside of the telescoping tube  15 . In this position, the spring  21  is compressed allowing the magnetic pin  16  to be fully housed inside of the telescoping tube  15 . 
         [0049]    Both  FIGS. 9A and 9B  show the magnetic locking pin  16  located inside of a retraction controller  40 . The retraction controller  40  is just one of the several stated internal mechanisms that could be compatible with this invention. For the invention to function properly, the magnetic looking pin  16  and auxiliary item mount  24  must be used in conjuncture with a pull-handle  14  with an internal locking pin mechanism. 
         [0050]      FIG. 9B  is a cross-sectional view of the auxiliary item mount  24  attached to the pull-handle  14 . The auxiliary item mount  24  is shown in the unlocked position. When the user presses the operating button  18  on the telescoping pull-handle  14 , the retraction controller  40  (or similar internal mechanism) draws the magnetic locking pin  16  inside of telescoping tube  15 . Because of the magnetic contact between the magnetic locking pin  16  and the switch magnet  32 , the adjoining locking switch  30  is also drawn inside of the auxiliary item mount frame  26 . When the locking switch  30  is drawn inside it releases the connection with the auxiliary adaptor  44  thus releasing the second bag  42  to from the wheeled luggage  12 . 
         [0051]      FIG. 10A  is an auxiliary bag  42  with auxiliary item attachment adaptor  44  being placed on the auxiliary item mount  24  of the wheeled luggage case  12 . In order to secure the auxiliary bag  42  on top of the wheeled luggage case  12 , the user must guide the auxiliary item attachment adaptor  44  on top of the auxiliary item mount  24 . The auxiliary item attachment adaptor  44  must be the same shape as the auxiliary item mount  24  in order to function properly. The two parts function as a male and female adaptor where the auxiliary item attachment adaptor  44  is placed on top of the auxiliary item mount  24 . 
         [0052]      FIG. 10B  shows the auxiliary bag  42  with auxiliary item attachment adaptor  44  that is secured on top of the auxiliary item mount  24  of the wheeled luggage case  12 . Here the auxiliary bag  42  is locked into place and cannot be removed from the wheeled luggage case  12  unless the traveler presses the operating button  18 . 
         [0053]      FIG. 11A  is a cross-sectional view showing the auxiliary item adaptor  44  locked on top of the auxiliary item mount  24 . The locking switch attachment  30  is engaged and prevents the user from removing the auxiliary bag  42  from the wheeled luggage case  12  (as shown in  FIG. 10B ). 
         [0054]      FIG. 11B  is a cross-sectional view showing the auxiliary item attachment adaptor  44  on top of the auxiliary item mount  24  in the unlocked position. The locking switch  30  is disengaged and allows the user to remove the auxiliary bag  42  from the wheeled luggage case  12  (as shown in  FIG. 10A ). 
         [0055]      FIG. 12A-D  shows one embodiment of an attachment adaptor  44 . The attachment adaptor  44  is constructed so that it can easily be slid on top of the auxiliary item mount  24 . This embodiment of the attachment adaptor  44  has been constructed as a single piece using molded plastic, although the attachment adaptor  44  could be made of various materials such as metal or resin and it could also be assembled using multiple parts. The main feature of the attachment adaptor  44  is that it has a sturdy catch plate  48  that prevents the auxiliary bag  42  from being removed from the wheeled luggage case  12  when the locking switch  30  is in the outward or locked position. The catch plate  48  can be integrated into the attachment adaptor  44  itself or added on as an additional part. The catch plate  48  can also be constructed in a variety of materials including but not limited to plastic, resin, or metal.  12 A shows the rear view of the attachment adaptor.  FIG. 12B  is a front view of the attachment adaptor.  FIG. 12C  is a side view of the attachment adaptor without a catch plate.  FIG. 12D  is an angled view of the attachment adaptor without a catch plate. 
         [0056]      FIG. 13A  is a front view of one embodiment of an auxiliary item mount  24  and a form adaptor  46 . The form adaptor  46  can be affixed to a auxiliary item mount  24  to change its shape so that it will fit the auxiliary item attachment adaptor  44  of the wheeled item  12 . This adaptor  46  allows a user to purchase an auxiliary item  42  which might not have the same shape as the auxiliary item mount  24  on the wheeled item  12  they want to use. The adaptor  46  solves the problem of the two different shapes allowing a different shaped auxiliary item mount  24 , to have it&#39;s shape changed making it compatible with any auxiliary item attachment adaptor  44 . The form adaptor  46  can be constructed in various shapes, sizes and materials so that different shaped auxiliary item attachment adaptors  44  can be snapped on to the auxiliary item mount  24 . 
         [0057]      FIG. 13B  is a front view of one embodiment of an auxiliary item mount  24  with a form adaptor  46  that has been fixed on the mount itself. The form adaptor  46  can be attached to the auxiliary item mount  24  by numerous means including attachment by screws, glue, adhesives, flush fit, snap-on system, etc. The auxiliary item mount  24  itself can also be constructed in different shapes and sizes so as to avoid the use of the form adaptor  46  altogether. 
       Method of Use for the Magnetic Locking Device System:
