Roller assisted low friction reefing grommet

Abstract

A roller assisted low friction reefing grommet that facilitates movement of a reefing line through the grommet. The roller assisted low friction reefing grommet includes a grommet ring having a roller therein that reduces friction of the line traveling through the grommet. A line channeling guide is formed within the interior of the grommet ring by a low friction material positioned on either side of the grommet, with a channel formed by the line channeling guide and the roller for receiving and guiding the reefing line.

Description

BRIEF DRAWING DESCRIPTION

(1) FIG. 1 is an elevation of the roller assisted low friction reefing grommet according to an embodiment of the invention.

(2) FIG. 2 is a side elevation of the roller assisted low friction reefing grommet, with the grommet ring in an exploded view.

DESCRIPTION OF PREFERRED EMBODIMENTS

(3) Referring to FIG. 1, the roller assisted low friction reefing grommet according to an embodiment of the invention is shown. A grommet ring 2 has a roller 4 positioned inside the grommet ring. The roller rotates about a shaft and bearing 6. The shaft is fixed to the interior of the grommet ring at each end of the shaft. The grommet ring may be circular.

(4) A line channeling guide has a first side 10 and a second side 12. The first side of the line channeling guide is opposite the second side of the channel guide. A channel 8 is formed between the first side of the line channeling guide and the second side of the line channeling guide, and the roller 4. As shown, and in a preferred embodiment, the roller is positioned between the first side of the line channeling guide and the second side of the line channeling guide and extends into the channel formed between the first side 10 and the second side 12. In one embodiment, the channel is formed by the first side of the line channeling guide, the second side of the line channeling guide, the roller and an upper portion of the interior of the grommet ring.

(5) The line channeling guide 10,12 is formed of low friction material. The low friction material may be a plastic. The low friction material may comprise, for example, polytetrafluoroethylene, polyethylene, polyimide, polyetheretherketone, polyphenylensulfide, nylon, polyoxymethylene, and polyester, or a combination thereof.

(6) FIG. 2 shows the roller assisted low friction reefing grommet as attached to a sail according to an embodiment of the invention. The grommet ring 2 is formed in two parts. One part of the grommet ring is constructed and arranged to attach to one side of a sail 18 and the opposite side of the grommet ring is attached to the opposite side of the sail. As shown in the embodiment of FIG. 2, one side of the grommet ring has threads 14 that extend through the sail into an opposite side of the sail. These threads engage corresponding threads 14 on the opposite side of the grommet ring. Accordingly, the grommet ring is attached to the sail by placing one side of the grommet ring through a hole or void formed in the sail and the opposite side of the grommet is threaded onto the other side of the grommet ring from the opposite side of the sail. This feature permits the grommet to be moved from sail to sail if the owner obtains new sails.

(7) In use, a reefing line 16 is pulled through the channel formed in the grommet ring 2 and over the roller 4 and through to the other side of the grommet ring. The roller and the line channeling guides 10,12 guide the reefing line through the grommet ring, while the roller and the line channeling guides reduce friction as the reefing line passes through the grommet. Pulling the reefing line through the grommet of the invention is expedited by the reduced friction provided.
