Surfboard tether

Claim 1

A device for securing a tether to a surfboard comprising (a) an anchor block imbedded in said surfboard, said anchor block having a non-circular internal recess in the upper portion thereof accessible at the exterior surface of said surfboard and a threaded perforation at the lower portion thereof, (b) a retainer having a portion of its exterior similarly non-circular to said recess in said anchor block said retainer having a cylindrical portion of its exterior having an external threaded surface, (c) a perforated tab having an aperture therein adapted to surround said threaded portion of said retainer, (d) a nut engaging said tab and said threaded portion of said retainer and adapted to secure said perforated tab to said retainer while permitting said perforated tab to rotate about said retainer at said aperture, (e) a tether attached to said tab at said perforation, (f) said retainer having a bolt, a threaded portion on said bolt threadedly engaging said threaded perforation of said anchor block, (g) and means at the exterior of said retainer defining a keyway for a key engageable with said bolt the use of said key enabling the rotation of said bolt with respect to said retainer and said anchor block whereby said bolt is secured to said threaded perforation in said anchor block and said tether is secured to said surfboard.

Claim 2

A device for securing a tether to a surfboard comprising (a) an anchor block imbedded in said surfboard, said anchor block having a non-circular internal recess in the upper portion thereof accessible at the exterior surface of said surfboard and a threaded perforation at the lower portion thereof, (b) a retainer having a portion of its exterior similarly non-circular to said recess in said anchor block said retainer having a cylindrical portion of its exterior having an external threaded surface, (c) a perforated tab having an aperture therein adapted to surround said threaded portion of said retainer, (d) a nut engaging said tab and said threaded portion of said retainer and adapted to secure said perforated tab to said retainer while permitting said perforated tab to rotate about said retainer at said aperture, (e) a tether attached to said tab at said perforation, (f) said retainer having a bolt, a threaded portion on said bolt threadedly engaging said threaded perforation of said anchor block, (g) and means at the exterior of said retainer defining a keyway for a key engageable with said bolt the use of said key enabling the rotation of said bolt with respect to said retainer and said anchor block whereby said bolt is secured to said threaded perforation in said anchor block and said tether is secured to said surfboard.

Claim 3

A device for removably securing a cable to a mobile object comprising: (a) an anchor fixed to said object, said anchor having a non-circular recess opening through the top of said anchor, said anchor being defined by (i) a bottom wall having an internally threaded axial opening therethrough, (ii) an opposing pair of flat axially extending anchor recess side walls, (iii) and a pair of curved axially extending anchor recess end walls; (b) a non-circular, retainer having a top, a bottom and a body portion, said body portion adapted to fit into said non-circular recess in said anchor, said body portion having a pair of flat spaced-apart axially extending retainer exterior side walls, and axially extending curved exterior retainer end walls between said top and bottom, (i) said retainer being adapted to cooperate with said flat and curved recess walls of said anchor, (ii) and said retainer side walls being shorter than said anchor side walls to leave a continuous gap between said bottom of said anchor and said axially extending end of said retainer within said recess; (c) an outstanding cap on said retainer at said top, said cap having radially extending wards defining a keyway; (d) a perforated tab having an aperture therein disposed around said retainer body portion below said cap and adapted to be nonreleasably engaged by said cable to secure said cable to said anchor, said tab being adapted (i) to nonreleasably engage said cable, (ii) and to rotate freely about said retainer body portion at said aperture; (e) said retainer having a bolt adapted to pass axially through said gap between said retainer and said anchor to engage said threaded axial opening in said anchor bottom wall, said bolt having (i) a head adapted to be disposed in said retainer below said cap, whereby a mating key having a complementary construction to said keyway in said cap and an axially extending radial ward thereon will pass axially into said retainer cap and into interengagement with said bolt to provide for rotation of said bolt within said anchor bottom wall to removably secure said cable to said mobile object.

Claim 4

A device for removably securing a cable to a mobile object comprising: (a) an anchor fixed to said object, said anchor having a non-circular recess opening through the top of said anchor, said anchor being defined by (i) a bottom wall having an internally threaded axial opening therethrough, (ii) an opposing pair of flat axially extending anchor recess side walls, (iii) and a pair of curved axially extending anchor recess end walls; (b) a non-circular, retainer having a top, a bottom and a body portion, said body portion adapted to fit into said non-circular recess in said anchor, said body portion having a pair of flat spaced-apart axially extending retainer exterior side walls, and axially extending curved exterior retainer end walls between said top and bottom, (i) said retainer being adapted to cooperate with said flat and curved recess walls of said anchor, (ii) and said retainer side walls being shorter than said anchor side walls to leave a continuous gap between said bottom of said anchor and said axially extending end of said retainer within said recess; (c) an outstanding cap on said retainer at said top, said cap having radially extending wards defining a keyway; (d) a perforated tab having an aperture therein disposed around said retainer body portion below said cap and adapted to be nonreleasably engaged by said cable to secure said cable to said anchor, said tab being adapted (i) to nonreleasably engage said cable, (ii) and to rotate freely about said retainer body portion at said aperture; (e) said retainer having a bolt adapted to pass axially through said gap between said retainer and said anchor to engage said threaded axial opening in said anchor bottom wall, said bolt having (i) a head adapted to be disposed in said retainer below said cap, whereby a mating key having a complementary construction to said keyway in said cap and an axially extending radial ward thereon will pass axially into said retainer cap and into interengagement with said bolt to provide for rotation of said bolt within said anchor bottom wall to removably secure said cable to said mobile object.
