Abstract (en)
A positionable jam cleat for use on a wind propelled vehicle. e.g. a surfboard, comprising a positioning sleeve (12) having an expandable circumference, slidably mounted on a respective one of the booms (30,31) and a cleat sleeve (18) having an inner diameter of a size such that when brought in contact with the outer surface of the positioning sleeve (12), the cleat sleeve (18) will compress the positioning sleeve (12), thereby increasing the frictional engagement of the boom (30,34) by the positioning sleeve (12), and with the cleat sleeve (18) having a jam cleat (20) formed on the outer surface thereof. The positioning sleeve (12) has an open seam (16) extending the length thereof and an inner diameter sufficiently smaller than the outer diameter of the boom (30,31). A lip (14) on the positoning sleeve (12) prevents the cleat sleeve (18) from being drawn over the line-receiving end of the positioning sleeve (12). The jam cleat (20) is formed by a pair of upstanding channel sides (21) on the outer surface of the cleat sleeve (18) and has a row of teeth (22) on the inward facings of the channel sides (21) and a bridge (26) joining the upper edges of the channel sides (21) at the line-receiving end thereof.
