        Abstract
A water craft anchor primarily comprising a shank assembly, arm assembly, and housing. The shank assembly swively connects to the arm members at a predetermined location. The arm members having a common shaft fixedly mounted inbetween. The housing assembly is rotably mounted and partially houses the common shaft and a chain member connects the shank assembly to the housing.             
         
        
            
                    Description
  
    
      
        II. BACKGROUND OF THE INVENTION
      
    
    
      
        1. Field of the Invention
      
    
    
      
        The present invention relates to a boat anchor, and more particularly, to the type that has a self release mechanism.
      
    
    
      
        2. Description of the Related Art
      
    
    
      
        Boating is a popular sport enjoyed by many. While boating, it is often necessary to set anchor to remain stationary. Various anchors have been designed in the past of many shapes and sizes. However, typically when an anchor is set, it becomes entangled with vegetation or structures on the floor of the body of water. Often, boaters spend much time and energy trying to free an anchor when severely entangled. In extreme cases, one may have to dive into the water to physically disentangle the anchor from the floor or structure it is entangled with.
      
    
    
      
        There is a need for an anchor with a self release mechanism. One that serves the purpose to effectively keep a vessel stationary when anchored, but with a built-in release mechanism to facilitate the deanchoring process.
      
    
    
      
        There are no similar boat anchors to the best of applicant's knowledge, that have a built-in self release mechanism and release when properly positioned.
      
    
    
      
        III. SUMMARY OF THE INVENTION
      
    
    
      
        It is one of the main objects of the present invention to provide a boat anchor that will free itself upon the application of a pulling force opposite from the angle where anchored.
      
    
    
      
        It is another object of this invention to provide an anchor that is easy to raise.
      
    
    
      
        It is yet another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.
      
    
    
      
        Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

                        Claims
        
                - 1. An anchor comprising:A) a shank assembly having first and second ends, including a pin member transversely mounted through said shank assembly at a predetermined distance from said first end towards said second end without reaching said second end; B) first and second arm members each having third and fourth ends, said third ends having a shaft fixedly mounted inbetween, said shaft having tabs radially extending at its distal ends, said fourth ends with interconnecting means for connecting with said pin; and C) a fluke assembly having two fluke members rotatably mounted to said shaft, including means for limiting the rotation of said fluke assembly, said means for limiting the rotation of said fluke assembly includes said fluke assembly comprising a housing between and connecting to said fluke members, said housing having edges to cooperate with said tabs where said tabs bias against said edges, and with further including means for disengaging said means for limiting the rotation of said fluke assembly.
- 2. The anchor set forth in claim 1, wherein said fluke assembly has a chain attached, with means for limiting the rotation of said fluke assembly.
- 3. The anchor set forth in claim 2, wherein said flukes are triangular in shape.
- 4. The anchor set forth in claim 3, wherein said housing has first and second vertexes extending perpendicularly therefrom, said first vertex when placed on a surface creates a fulcrum effect, which causes either of said two fluke members to contact said surface.
