US 5,706,680 A · Surfboard locks

Abstract

Locking devices for surfboards, sailboards and skateboards which clamp about tapered sides of surfboards and sailboards adjacent the fins. The devices clamp about skateboard sides between the two sets of wheels. One version has a hook ended rod that grips about a board side and another end that attaches by a padlock to a second rod which hooks about another board side. The first rod end has through holes that insert into a cylinder end of the second rod. The further one rod is inserted into the second cylindrical rod end, the closer the spacing between the hooks. A padlock in the through-holes connect the rods. Another version has a padlock in the second cylindrical rod where grooves on the first rod end are locked in place. Another version has a perpendicular extension bracket that wraps about one surfboard or sailboard fin. Another version uses a top flat plate that hingedly connects to a curved bottom plate. Opposite ends of the plates have matching through-holes for a padlock. Another version has side-by-side holes in both plates to accommodate different board widths. A cable connects the devices to a pole or bikerack.

A locking device in combination with a recreation board, the recreation board chosen from one of a surfboard and sailboard, the device comprises:

a top planar plate having a first end and a second end, the second end having a through-hole, the top plate overlying an upper surface of the recreation board having fins with first and second tapered sides, the recreation board having a narrow width end adjacent to the fins and a wide width middle;
a hinge having one side connected to the first end of the top plate adjacent the first tapered side of the recreation board in front of the fins;
a lower curved plate having a first end and a second end, the first end of the lower curved plate connected to a second side of the hinge, the second end of the lower curved plate having a through-hole, wherein the top plate and the lower curved plate rotate relative to the hinge and the through-holes of each plate match together, the lower curved plate abutting against a lower curved surface and the first and the second tapered sides of the recreation board;
and
a padlock for connecting through the top plate through-hole and the lower curved plate through-hole adjacent the second tapered side, the top plate and the lower curved plate being positioned between the narrow width end and the wide width middle of the recreation board.
