Leash anchor for surfboard

Abstract

An anchor for mounting on a surfboard adjacent its trailing end for connection to a leash includes a plug element defined by opposed front and back ends and elongate, spaced-apart non-parallel sides extending from the front and back ends. The elongate sides may taper inwardly, and the plug element is sized to be inserted and seat within a complementary cavity formed in the deck of the surfboard, adjacent its trailing edge. The cavity is dimensioned with tapering sides as well, thereby to inhibit rearward movement of the plug element relative to the surfboard. The plug element, in a preferred embodiment, has elongate sides which give the plug element the overall appearance of a triangle, or truncated pyramid shape.

What is claimed is: 
     
         1 . An anchor for mounting on a surfboard adjacent its trailing end for connection to a leash comprising:
 a plug element formed as a unit defined by opposed front and back ends and elongate, spaced-apart non-parallel sides extending from the front and back ends,   wherein the plug element is sized to seat within a complementary cavity formed in the surfboard, wherein the cavity is dimensioned to inhibit rearward movement of the plug element relative to the surfboard.   
     
     
         2 . The anchor as defined in  claim 1  wherein the non-parallel sides of the plug element taper inwardly from the plug element's front end to its back end. 
     
     
         3 . The anchor as defined in  claim 2  wherein an opening is provided on the back end of the plug element leading to an internal passage which emerges to an opening adjacent the upper surface of the plug element so that a cord may be threaded through the opening on the back end, the passage and outwardly through the upper opening. 
     
     
         4 . The anchor as defined in  claim 3  wherein the non-parallel sides are provided with spaced-apart ribs. 
     
     
         5 . The anchor as defined in  claim 4  wherein the spaced-apart ribs, on each of the non-parallel sides, define sides which taper to a profile conforming generally to the taper of the non-parallel sides. 
     
     
         6 . The anchor of  claim 5  wherein the non-parallel sides are dimensioned so that the plug element is formed generally in a triangular shape. 
     
     
         7 . An assembly of an anchor mounted in a cavity formed on the deck of a surfboard adjacent its trailing edge for connection to a leash comprising:
 a plug element formed as a unit defined by opposed front and back ends and elongate, spaced-apart non-parallel sides extending from the front and back ends,   a complementary cavity formed in the surfboard's deck adjacent its trailing edge, the cavity defined by sides dimensioned to enable the plug element to be inserted and seated therewithin but which also inhibit the plug element from rearward movement relative to the surfboard.   
     
     
         8 . The anchor and cavity assembly as defined in  claim 7  wherein the non-parallel sides of the plug element taper inwardly from the plug element's front end to its back end. 
     
     
         9 . The anchor and cavity assembly as defined in  claim 8  wherein an opening is provided on the back end of the plug element leading to an internal passage which emerges to an opening adjacent the upper surface of the plug element so that a cord may be threaded through the opening on the back end, the passage and outwardly through the upper opening. 
     
     
         10 . The anchor and cavity assembly as defined in  claim 9  wherein the non-parallel sides are provided with spaced-apart ribs. 
     
     
         11 . The anchor and cavity assembly as defined in  claim 10  wherein the spaced-apart ribs, on each of the non-parallel sides, define sides which taper to a profile conforming generally to the taper of the non-parallel sides. 
     
     
         12 . The anchor and cavity assembly as defined in  claim 11  wherein the non-parallel sides are dimensioned so that the plug element is formed generally in a triangular shape.
