Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of provisional patent application Ser. No. 61/995,156, filed 2014 Apr. 2 by the present inventor. 
     The mechanics of attaching items to the ground vary from the simple to the complex. Generally speaking, a mechanism is driven into the ground with varying degrees of holding capability. 
     The majorities of these anchors are meant to be semi-permanent due to the limited capability they possess. Some of the more permanent anchors involve drilling holes in the earth and filling with cement, followed by placing a coupler into the wet cement and then waiting for the application to set up and cure before being able to be utilized. 
     Common ground anchor systems are known to suffer from a number of disadvantages: 
     (a) their applications lack strength in performance and durability; 
     (b) their semi-permanent nature give them a probability of failure when tested; 
     (c) an anchor required for a large application tends to be an expensive and time consuming installation, yet still deals with the probability of failure. 
     SUMMARY 
     In accordance with one embodiment, the ground anchor comprises a coupler, a ground plate, and a main shaft giving direction of installation into ground. 
     Advantages 
     Accordingly, several advantages of one or more aspects are as follows: to provide ground anchors that are permanent, minimally invasive to the ground, relatively inexpensive, easily installed, and supply extreme durability in usage. Other advantages of one or more aspects will be apparent from an examination of the drawings and ensuing description.

     DETAILED DESCRIPTION 
     FIGS.  1   a  and  1   b , FIG.  2 , and FIG.  3   
     First Embodiment 
     Ground anchor device  18  comprises a main shaft  28  connecting a ground plate  20 , which in turn is connected to a coupler  24 . Length of main shaft  28  is designed for quick and secure placement of ground anchor device  18 . Coupler  24  has bolt holes  26  which allow whatever is inserted to be secured with a bolt. Top of coupler area  48  provides additional area for securing. 
     Ground plate  20  has oblong holes  22  for insertion of additional shafts into ground plate  20 . The width of the oblong holes  22  are sized according to the diameter of the additional shafts creating a snug fit, while the length of the oblong holes  22  are sized to allow varying angles of installment of additional shafts. After additional shafts are installed they are connected in place. 
     Main shaft  28  with top of main shaft protruding  42  and bottom of main shaft  28  showing chamfer  32 . Main shaft  28  is connected to ground plate  20  of ground anchor device  18  and additional shafts are driven in place. In addition, additional shafts are left protruding slightly out of ground plate  20  prior to connecting. 
     Operation 
     Initially, chamfer  32  end of main shaft  28  is driven vertically into ground to the bottom of ground plate  20 . Driving of main shaft  28  into ground is accomplished with a powered device such as a demolition hammer with driver bit placed over main shaft  28  that is protruding  42  to accompany driver bit. Once ground anchor device  18  is driven snugly into the ground, the next step is driving additional shafts through oblong holes  22  into the ground. Once additional shafts are driven into place, it is time to connect them at areas to connect  44 . 
     Once the additional shafts are connected, the installed ground anchor device  18  is now ready to accept pipe, pole, cable, chain, rope, wire, also different shaped items such as square or triangle post by the use of an adapter to connect up to coupler  24 , secure attachment by bolt at bolt holes  26 , or a connection at top of coupler connection area  48  or both. 
     To summarize, my invention comprises a coupler, ground plate, and main shaft able to be accurately driven into the ground where needed and, along with driven additional shafts, becoming more secure with each additional shaft added and then connected in place forming an expanded underground anchorage and support structure. 
     ADVANTAGES 
     From the description, a number of advantages of one embodiment of my ground anchor device becomes evident. 
     (a) The ground plate is able to hold many secondary shafts at a centralized location, providing a reinforced center point of anchor placement and structure. 
     (b) The nature of additional shafts, uniformly spread out, supplies a broad base of strength, increasing anchor durability. 
     (c) The connecting of all pieces involved provides a more permanent application, fortifying durability and duration of installation. 
     CONCLUSION, RAMIFICATIONS, AND SCOPE 
     Furthermore, the reader will see that the embodiments of the ground anchor device have the additional advantages in that: 
     It is more durable; 
     It is quicker to install; 
     It is minimally disturbing to the ground; 
     It is more versatile; 
     It is suitable for a wide range of ground conditions; 
     It is cost effective; 
     It is frost heave resistant; 
     It is suitable for a wide range of anchoring and support duties; 
     It is earthquake resistant; and 
     It is suitable for anchoring most anything to the ground. 
     Although the description above contains many specificities, these should not be thought as to limit the scope of the embodiments, but as simply providing illustration as one of several embodiments. For example, the coupler can have other shapes, such as rectangular, square, etc.; the main shaft and ground plate can have other shapes also. 
     Thus, the scope of the embodiments should be determined by the appended claims and their legal equivalents, rather than by examples given.
