Boat anchor

Abstract

An anchor for mooring a water craft to a shore or beach that included a straight shaft that is pointed on one end and is arranged on connecting to a torque producing device on its other end. The shaft includes an auger fixed thereto adjacent to the pointed end and is to loosely fitted into a cylindrical tube wherefrom fins or blades are attached to extend oppositely outwardly from the cylindrical tube sides that are sloped outwardly from their lower ends to facilitate their travel into the shore or beach. A torque applying handle or driver is provided for attachment to the shaft other end, and a mooring line connector is secured to the cylindrical tube, adjacent to a top end thereof.

1 . A boat anchor comprising, a vertical shaft having a first lower and a second upper ends, where said first end is shaped to have a pointed tip, and said shaft first end, adjacent to said pointed end, includes a spiral, screw, or auger device located on the exterior surface of said shaft, and said shaft second end includes a centrally located cavity formed to receiver a driver means fitted therein; a cylindrical tube is provided for loosely fitting over said shaft between said first and second shaft ends to be in a sliding relationship; at least a pair of blades or fins are individually attached to extend outwardly from the exterior surface of said cylindrical tube and a mooring line attachment means is fixed to said cylindrical tube outer surface for maintaining a mooring line thereto; and a torque producing device is arranged for connection to said shaft second end, coupling into said cavity to provide a rotational torque on the shaft, and said torque producing device is attached to said shaft by a coupling arrangement. 
   
   
       2 . The boat anchor as recited in  claim 1 , wherein the interior diameter of said tube is greater than the outside diameter of said shaft creating a space or gap, and the width of said space or gap is such as to accommodate a passage of debris out from between opposing outer and inner surfaces of said shaft and cylindrical tube. 
   
   
       3 . The boat anchor as recited in  claim 3 , wherein, with the shaft centered in the cylindrical tube, the space or gap is from one eighth to one half of an inch. 
   
   
       4 . The boat anchor as recited in  claim 1 , wherein a pair or blades or fins are individually secured along the cylindrical tube or sleeve longitudinal axis to project outwardly from opposite sides thereof. 
   
   
       5 . The boat anchor as recited in  claim 1 , wherein the auger has at least one turn. 
   
   
       6 . The boat anchor as received in  claim 1 , wherein the torque coupling device driver means is a hand bar that includes a body with hand engaging bars extends oppositely therefrom and an attachment collar arranged for connection to the top end of the shaft. 
   
   
       7 . The boat anchor as recited in  claim 1 , wherein the torque producing device is a power device that includes a body wherefrom hand engaging means extend out from opposite sides thereof and has a sided drive extending therefrom for fitting in a sided opening formed in the shaft second or top end for turning said shaft. 
   
   
       8 . The boat anchor as recited in  claim 1 , wherein the mooring line attachment means is a ring that is secured onto, to extending outwardly from the cylindrical tube outer surface, proximate to a top end thereof. 
   
   
       9 . The boat anchor as recited in  claim 1 , wherein the mooring line attachment means includes a body for attachment onto, to extend outwardly from, the cylindrical tube outer surface, proximate to a top end thereof, and has a guide pulley pivotally mounted thereto, and a pawl secured to said body to pivot towards a sheave of said guide pulley, moving teeth formed along a side of said pawl into engagement with a mooring line that has passed around said guide pulley sheave.
