CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority of U.S. Provisional Patent Application No. 60/862,377, filed on Oct. 20, 2006, in the United States Patent &amp; Trademark Office, the disclosure of which is incorporated herein by reference in its entirety. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present general inventive concept relates to a hinged magnetic support and positioning assembly and method thereof, and more particularly, to an assembly having at least two industrial strength magnets connected by a hinge to support and position elements during construction. 
         [0004]    2. Description of the Related Art 
         [0005]    Construction applications generally involve connecting various pieces of material together. Some applications involve very large pieces of material and/or pieces of material having awkward shapes. Such pieces present a user with significant difficulty with respect to maneuvering the pieces prior to joining. This process is further aggravated if the pieces must be joined at precise points with little or no tolerance for error. 
         [0006]    Convention methods generally require a user and several assistant users to assist with maneuvering and joining large and/or awkward pieces of material. As such, conventional methods present a difficult process, require additional manpower, and are therefore inefficient. 
         [0007]    Also involved in construction applications is a variety of construction equipment, some of which is required to be secured in place during use. One such piece of equipment is a hole former, which is used in the Precast Industry to create a hole for pipes to enter manholes. Manholes range in diameter from 4′ to over 10′ with varying depths. 
         [0008]    Convention methods either bolt the hole former to a steel core of the manhole or shell, or position and tie the hole former to steel wire mesh, which is around the core. Both methods are time consuming, requiring the user to spend extra time attaching and detaching the hole former. Other disadvantages of these methods include that the hole former and steel core must both be pre-drilled with a bolt hole, which lowers the mechanical integrity of both. Further, tying the hole former does not present a secure means of engagement. 
       SUMMARY OF THE INVENTION 
       [0009]    A principal object of the present general inventive concept is to provide a hinged magnetic assembly having a plurality of industrial strength magnets. 
         [0010]    Another object of the present general inventive concept is to provide at least two industrial strength magnets connected by a hinge capable of holding construction elements in a desired orientation. 
         [0011]    Another object of the present general inventive concept is to provide at least two industrial strength magnets connected by a hinge capable of holding utility hole formers in place.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0026]    Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept be referring to the figures. 
         [0027]      FIG. 1  illustrates a hinged magnet assembly  1  including at least one magnet  5  of industrial strength coupled with at least one other magnet  6  of industrial strength. The magnets  5  and  6  are respectively sandwiched between attachment layers  3  and  8  to respectively secure the magnets  5  and  6  to outer plates  4  and  7 . The magnets  5  and  6  can be cam magnets with notched or floating sides, flat magnets, or any other like magnets. 
         [0028]    The outer plates  4  and  7  and attachment layers  3  and  8  coordinate to provide a buffer zone  9  between the magnets  5  and  6  and arms  10  and  11 . The buffer zone  9  prevents the magnets  5  and  6  from interfering with movement of the arms  10  and  11 , and provides increased magnetization in a desired direction, i.e., on a top face surface  20  and  30  or a bottom face surface  21  and  31  of the magnets  5  and  6 . 
         [0029]    The two arms  10  and  11  of the hinged magnet assembly  1  engage the magnets  5  and  6  at respective side surfaces  25  and  35 . The two arms  10  and  11  connect the magnets  5  and  6  to each other with each magnet  5  and  6  having a point of rotation  15  and  16 . 
         [0030]    In the preferred embodiment, the magnets  5  and  6  are identically sized and shaped. However, the magnets  5  and  6  may be sized and shaped differently depending on factors such as, but not limited to, the intended application of the magnets  5  and  6 . 
         [0031]    The arms  10  and  11  hold the two magnets  5  and  6  together and are coupled to define a specific range of motion with respect to rotation of the magnets  5  and  6 . The range of motion allows either or both magnets  5  and  6  to independently rotate around the points of rotation  15  and  16  with respect to each other. 
         [0032]    Lock bolts  40  and  41  may be used to secure either or both magnets  5  and  6  at desired orientations with respect to each other to allow a user to configure the magnet assembly  1  to facilitate its use in a specific application. The length, width, height, and magnetic strength as well as desired orientation of the magnets  5  and  6  will vary from one application to another. 
         [0033]    In use, the magnets  5  and  6  are positioned in a desired orientation and positioned between two steel parts (not illustrated) that are to be joined. Upon position the magnets  5  and  6 , the lock bolts  40  and  41  can be tightened to lock the magnets  5  and  6  at the desired angle to avoid inadvertent repositioning during use, e.g., upon engagement with the steel parts. 
         [0034]    The hinged magnet assembly  1  holds the steel parts in place to facilitate engagement of the steel parts via soldering, welding, bonding, or the like. The steel parts can be held in any position, e.g., in contact with each other or with space therebetween. 
         [0035]    The hinged magnet assembly  1  allows for less movement during bonding. If the two steel pieces are above the head of the user pre-engagement, it is advantageous to be able to securely position the pieces. 
         [0036]    The hinged magnet assembly  1  may be used for many applications, including, but not limited to use with utility plant products, including manholes, catch basins, and another other applications where two steel parts are to be joined together. 
         [0037]    In another embodiment, the hinged magnet assembly  1  may be used with a utility hole former. The hole former is a large diameter hole former used in the precast industry to create a hole for pipes to enter a manhole. Manholes range in diameter from 4′ to 10′ plus and come in various heights. 
         [0038]    It is known in the precast industry to either bolt the hole former to the steel core or shell and tie to it steel wire mesh which is around the core. The hinged magnet assembly  1  may be used to hold the hole former in place. The hole former is made of steel or other metal material that is attached to magnets  5  and  6 . One magnet  5  and  6  of the hinged magnet assembly  1  attaches to the steel of the hole former and the other magnet  5  and  6  assembly of the hinged magnet assembly  1  is placed in position on the core or shell. 
         [0039]    Several advantages of the present general inventive concept for use with hole formers is that the hinged magnet assembly  1  provides flexibility for placement without putting holes in the core or jacket. 
         [0040]    The hinged magnet assembly  1  also provides for less movement than attaching to steel wire mesh. The use of the hinged magnet assembly  1  eliminates the need for holes in forms and eliminates the movement of floating hole formers. 
         [0041]    Having now described the features, discoveries and principles of the general inventive concept, the manner in which the general inventive concept is constructed and used, the characteristics of the construction, and advantageous, new and useful results obtained; the new and useful structures, devices, elements, arrangements, parts and combinations, are set forth in the appended claims. 
         [0042]    It is also to be understood that the following claims are intended to cover all of the generic and specific features of the general inventive concept herein described, and all statements of the scope of the general inventive concept which, as a matter of language, might be said to fall therebetween.
