Abstract
A quick-connect mast step assembly has a round main body bolted to the surface of a sail board wherein the upper surface of the body has a T-slot for receiving a mast shoulder bolt and a plug associated with the T-slot which, when rotated, prevents disengagement of the shoulder bolt from the T-slot, the body being bolted to a fin box in the upper surface of the sail board which allows easy adjustment of the position of the assembly.
Claims4
A mast stepping device for securing a mast to a sail board comprising,
- a body having upper and lower surfaces, a central bore, and t-slot means formed in the upper surface for receiving a mast shoulder bolt, and
- a mounting bolt extending downwardly from the central bore and being perpendicular to the lower surface.
- wherein the t-slot means comprises,
- inner, middle and outer circular spaces arranged in ascending order with the inner space being concentric with the central bore, and
- a circular plug rotatably mounted in the outer space, the circular plug having an arcuate indentation which, when aligned with the middle space forms an opening for receiving the mast shoulder bolt, the inner space and middle space having a slot formed at a bottom portion thereof which facilitates movement of the mast shoulder bolt to a central position in the central bore, the mast shoulder bolt being held in the central position by rotating the circular plug such that a circumferential edge abuts the mast shoulder bolt.
