Abstract
A roller reefing system for use on the existing forestay of a sailboat such that it surrounds the forestay when installed and in use. The system includes a furling member which is composed of a plurality of indentical cross section members, each of which has a longitudinal opening to receive the forestay, and a connecting sleeve for connecting adjacent members together and for locating a bearing element within the longitudinal opening. The roller reefing system may be easily installed on the existing forestay of a sailboat without modification to the forestay.
Claims7
In a roller reefing system for sailboats employing a forestay wherein the forestay of the sailboat may remain in place and wherein the roller reefing system surrounds the forestay when installed and in use, said improvement comprising:
- the roller reefing system including a furling member comprising a plurality of substantially identical cross section members and of total length slightly less than the overall length of said forestay;
- each of said plurality of substantially identical cross section members having a longitudinal opening therethrough to provide a continuous opening through said roller reefing system for receiving said forestay and for receiving support from said forestay when in use;
- a union between each of said plurality of members, said union comprising:
- a sleeve extending partially into the end of each adjoining member within the said continuous opening and surrounding the forestay;
- bearing means at each of said unions;
- said bearing means comprising a split cylindrically shaped low friction solid;
- said bearing means having a central opening dimensioned to encircle the forestay in sliding engagement therewith;
- the exterior of said bearing means having an external dimension corresponding to the internal dimension of said sleeve and in press fit therewith to retain said bearing in position;
- wherein said bearing means includes an annular groove therein;
- and
- securing means accessible from the exterior of said adjacent members for securing said sleeve to both said adjacent members;
- one of said securing means extending into the annular groove of said bearing means to additionally secure said bearing means from longitudinal movement within said roller reefing system;
- and
- means coupled to the lowermost of said members for rotating said roller reefing system.

- said bearing means having a central opening dimensioned to encircle the forestay in sliding engagement therewith;
- the exterior of said bearing means having an external dimension corresponding to the internal dimension of said sleeve and in press fit therewith to retain said bearing in position;
- wherein the ends of adjacent members include mating recesses thereon spaced from said opening therein;
- including locking pin means extending into said mating recesses to provide torsional strength to said system.
