CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application is based on and claims priority to U.S. Provisional Application No. 60/569,555, filed May 10, 2004, the contents of which is incorporated fully herein by reference. 
     
    
     BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     This invention is in the field of exercise equipment, particularly, to an exercise method involving omni-directional use of a treadmill and, more particularly, to an exercise device that facilitates such omni-directional use.  
         [0004]     2. Description of the Related Art  
         [0005]     A treadmill is a piece of exercise equipment that simulates the action of walking or running while allowing the user to remain essentially in one place. A typical treadmill consists of a flat stationery member, sometimes referred to as a deck, and a substantially vertical member resembling a podium, sometimes referred to as the neck.  
         [0006]     The deck typically has a moving surface of some kind, usually a belt driven by motorized rollers at the front and back of the deck. The surface of the belt on which the user treads moves in a direction away from the podium, and the user walks or runs in a direction towards the podium, thereby creating a moving walkway on which to exercise. Most treadmills have user-definable variables, such as speed, incline of the deck, and the like, all of which allow the user to simulate various walking and running conditions. Using prior art treadmills allows the user to develop muscles that are typically exercised during forward running or walking.  
         [0007]     As part of a training regimen, many athletes perform exercises designed to develop muscles other than those that are developed from forward running or walking. Since treadmills are designed for forward operation only, some athletes forgo the use of the treadmill and do exercises in a gym or on a field whereby they move from side to side, or walk or run backwards, to develop the muscles associated with such movements. It would be desirable, therefore, to be able to simulate the same sideways and backwards movements in a stationary location, such as on a treadmill.  
       SUMMARY OF THE INVENTION  
       [0008]     In accordance with the first embodiment of the present invention, a standard treadmill is utilized in a manner contrary to that suggested by the manufacturer, to increase the benefit to be gained from use of the treadmill. More specifically, in accordance with the present invention, a user stands in a side-ways position on the platform of a treadmill (e.g., so that the podium is situated either to the left or right of the user, depending upon which sideways direction the user is standing), and then operates the treadmill platform. The user then performs a side-to-side striding technique whereby he or she is essentially walking sideways on the treadmill platform. This provides a workout for various portions of the body that are not typically worked out during use of the treadmill in the traditional manner.  
         [0009]     Similarly, turning 180° from the recommended position (so that the user is facing away from the podium) and then walking on the treadmill platform while it is in a moving state allows the user to simulate a backwards walking movement, which, again, works out different muscles than those that are worked out while operating the treadmill in the recommended forward-walking orientation.  
         [0010]     A second embodiment of the present invention is an exercise device incorporating a treadmill platform and treadmill podium, whereby the user may walk/run on the treadmill, not only in the forward direction, but also in the side-to-side and backwards directions described above, while still facing the podium. This embodiment of the present invention provides a treadmill having a podium that can be adjusted with respect to the platform, so that regardless of the direction of travel in which the user is traveling on the platform (forward, side-to-side, or backwards), the user will always be facing the podium. This is accomplished by providing a pivoting podium element that pivots with respect to the platform.

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0017]      FIGS. 1A and 1B  illustrate the present invention in the “normal” treadmill position. A deck assembly  102  and a podium assembly  104  are integrated in such a way that they resemble the typical treadmill. More specifically, deck assembly  102  includes a moving belt  122  bordered on either side by non-moving side elements  124  and  126 . Side elements  124  and  126  are frequently used by users to stand on when the user wants to stop immediately and does not want to wait for the moving belt  122  to come to a complete stop. In a well known manner, drive motors and rollers (not shown) are controllable to move the moving belt  122  in a direction along the longitudinal axis of deck assembly  102  such that the moving surface on which the user treads is moving away from the podium assembly  104 , as indicated by the directional arrows  120  shown on the moving belt  122 .  
         [0018]     The podium assembly  104  includes a display/control area  106 . The display/control area  106  typically will include operational controls, displays for displaying speed of the belt, calories burned, time elapsed, etc. Many treadmills also included handles  108  to give the user something to grab onto for support in the event of a stumble.  
         [0019]     Legs  110  and  112  of podium assembly  104  provide a support means for display/control area  106  and are connected to a base  114 . In accordance with the present invention, base  114  is connected to a pivoting platform  116 . Pivoting platform  116  is situated between deck assembly  102  and a base platform  118 . Pivoting platform  116 , when positioned as shown in  FIGS. 1A and 1B , has a longitudinal axis that is parallel with the longitudinal axis of deck assembly  102 . As will be described in more detail below, pivoting platform  116  is pivotally mounted between deck assembly  102  and base platform  118 , so that it may move about the perimeter of deck assembly  102 .  
         [0020]      FIGS. 2A and 2B  illustrate the present invention in a right-facing sideways position. In this position, the podium assembly  104  has been rotated 90° to the right from “normal” so that a user facing the podium assembly  104  is facing perpendicular to the direction of movement of the belt  122 , with the belt moving from the user&#39;s left to the user&#39;s right. In this position, the longitudinal axis of pivoting platform  116  is perpendicular to the longitudinal axis of deck assembly  102 . Since the pivoting platform  116  can pivot between deck assembly  102  and base platform  118 , the podium assembly  104  is movable to this position. In a preferred embodiment, a locking mechanism may be used to assure that the podium assembly  104  remains in this position during use. Numerous locking mechanisms are known in the art and the specific locking mechanism used is a matter of design choice and will be apparent to a designer of ordinary skill in the art.  
         [0021]     Once the device has been pivoted to this position, the user simply stands on the deck assembly  102  facing the podium assembly  104 , and activates the movement of the belt  122 , and begins sideways striding. It is recommended that, at least at first, the speed of the belt  122  be kept very low, e.g., 2 mph or less, at least until the user gets used to the sideways motion. By using the device in this position, the user will develop muscles needed to stride from side to side.  
         [0022]      FIGS. 3A and 3B  illustrate the present invention in the backward position. As can be seen, the podium assembly has been pivoted 180° from “normal” so that now a user facing the podium assembly  104  must walk backwards when the belt  122  is operating. By using the device of the present invention in this manner, the user develops muscles that are utilized during the act of walking backwards.  
         [0023]     Finally,  FIGS. 4A and 4B  illustrate the device of the present invention in the left-facing sideways position. As can be seen, the podium assembly  104  has been pivoted 90° to the left of normal, and a user of the device facing the podium assembly  104  will be standing perpendicular to the direction of movement of the belt  122 . In this position, a user will start the belt  122  and will stride side-to-side, with the belt  122  moving from the user&#39;s right to the user&#39;s left. This action will develop muscles used during this side-to-side motion.  
         [0024]     As noted above, the present invention requires that the pivoting platform  116  be able to pivot with respect to the deck assembly  102  and base platform  118 . Numerous methods of enabling such a pivot motion will be apparent to a designer of ordinary skill in the art. One such method is illustrated in  FIG. 5 .  FIG. 5  illustrates, in exaggerated form, a side and rear view (looking along arrow “A” in the side view) of a configuration enabling pivoting platform  116  to pivot as described.  
         [0025]     Referring to  FIG. 5 , a bracket  530  is affixed to deck assembly  102  along the side elements  124  and  126 . Since belt  122  wraps around and underneath deck assembly  102  in a well known manner, there must be clearance between bracket  530  and deck assembly  102  to allow free travel of the belt  122 . A bolt  532  affixes bracket  530  to base platform  118 . Bolt  532  passes through pivoting platform  116  such that bracket  530  (and deck assembly  102  attached thereto) is fixedly attached to base platform  118  while allowing pivoting platform  116  to move freely therebetween. As noted above, locking mechanisms may be provided to lock pivoting platform  116  in a desired position.  
         [0026]     Although the example of  FIG. 5  illustrates the rotation of podium assembly  104  around a fixed point (bolt  532 ), it is understood that the movement of the podium  104  about the perimeter of deck assembly  102  can be achieved using numerous other methods. For example, the pivoting platform  116  could be slotted and engage with a stud or other member cooperating with the slot(s) of pivoting platform  116 , and the podium assembly  104  could thus be moved about the perimeter by pulling the pivoting platform  116  outward, moving it around to the desired position, and then sliding it back to engage it in place, in the new position, between deck assembly  102  and base platform  118 . These methods are included as part of the present invention.  
         [0027]     Further, although the figures illustrate the podium assembly pivoted to positions whereby the longitudinal axis of the pivoting platform is either perpendicular to or parallel to the longitudinal axis of deck assembly  102 , the podium assembly can as well be pivoted to any position whereby the longitudinal axis of pivoting platform  116  is between a parallel orientation and a perpendicular orientation with respect to the longitudinal axis of the deck assembly  102 .  
         [0028]     For the display/control area  106  to be functional, the only requirement different from that of the ordinary treadmill is that electrical connections between the podium assembly  104  and the deck assembly  102  (including the motor and any sensors) be maintained in an operational state. There are numerous methods known in the art for accomplishing the maintaining of these connections, including the use of wiring harnesses that are of sufficient length to enable such movement and/or the use of sliding electrical contacts that slide along a conductive area so that, even when rotated, the electrical contacts maintain contact with the conductive area on which it slides, thereby maintaining the electrical connections. Further, it is contemplated that wireless connections could be used between the controls and the elements that they control, and/or the display devices and the elements driving them, to thus avoid the need for physical electrical connections between the display/control area  106  and the deck assembly  102 .  
         [0029]     By providing an upper support assembly and display that rotates in the described manner, a user may safely use a treadmill to exercise muscles used in normal frontward movement, side-to-side movement, and backwards movement. The user is always facing the display device and thus does not have to turn to see them. Further, if the podium is equipped with handles, the handles are oriented for use to give the user stability. The present invention provides a treadmill having a podium that can be adjusted with respect to the platform, so that regardless of the direction of travel in which the user is traveling on the platform, the user will always be facing the podium.  
         [0030]     Although the present invention has been described with respect to a specific preferred embodiment thereof, various changes and modifications may be suggested to one skilled in the art and it is intended that the present invention encompass such changes and modifications as fall within the scope of the appended claims.
