Abstract
A sailboat spar track cleaner for cleaning a sail track on a mast or other spar comprises a U-shaped housing that fits over the track, with adjustable track cleaners having abrasive contact surfaces extending inwardly from the sides of the housing into contact with the track. An adjustable spacer attached to a back of the U-shaped housing bears against the track and controls the position of the housing so that the track cleaning elements are properly aligned with grooves in the track. The track cleaner is mountable on a track in a sailboat and movable along the length of the track using conventional lines, such as the halyard and a downhaul in the case of a mast.
Description




BACKGROUND OF THE INVENTION




The present invention relates to a cleaning fixture for cleaning a sail track on a mast or other spar of a sailboat.




A sailboat mast, as well as other sail-supporting spars on a sailboat, is fitted with a longitudinal track in one form or another that extends the length of the mast. Sails usually have connector fixtures, such as slides, slugs, or cars, attached to the edge of the sails that interconnect the sails with the track and permit the sails to slide along the edges of the track.




A problem encountered with most sailboats is that the tracks, over a period of time, become dirty and clogged. This impairs the free movement of the sail connector on the track and makes it more difficult to raise and lower the sail. This is especially a problem in lowering a sail, wherein sails are generally lowered from a mast by means of gravity. Where the track is so clogged that the cars or connectors stick on the mast, it becomes difficult to lower the sail.




The upper portion of the track on a sailboat mast is difficult to access. There are devices that are designed to travel along the track in order to spray a lubricant on the track. However, lubricants tend to attract more grime and dirt and sometimes increase problems with track clogging. When a track is clogged in a larger sailboat, a person has to climb the mast in order to clean the track. An object of the present invention is to provide an improved sailboat track cleaner that is adjustable for different conditions and can be raised or lowered from the deck using conventional sailboat lines.




SUMMARY OF THE INVENTION




The present invention comprises a sailboat spar track cleaner for cleaning a sail track on a mast or other spar comprising a U-shaped housing that fits over the track, with adjustable track cleaners extending inwardly from the sides of the housing into contact with the track. An adjustable wheel attached to a back of the U-shaped housing bears against the track and controls the position of the housing so that the track cleaning elements are properly aligned with grooves in the track. The track cleaner is mountable on a track in a sailboat and movable along the length of the track using conventional lines, such as the halyard and a downhaul in the case of a mast.




The track cleaner elements can take different form is, depending upon the particular style and configuration of the track being cleaned. An abrasive pad can be used as the track cleaning material, so that grime is removed by abrasion and polishing the track instead of by depositing additional grime-collecting liquid on the track surface.




These and other features of the present invention are described below and shown in the appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT




Referring now to the drawings, a sailboat


10


comprises a mast


12


and a hull


14


. The mast includes a track


16


to which a sail is mounted by means of a connector fitting, such as a slide, slug, or a car or other conventional fitting. The sail is raised up the mast by means of a halyard line


18


. The halyard extends over a pulley or block


20


at the top of the mast and then downwardly on a rear side of the mast where it connects to the upper end of the sail.




One exemplary configuration of a track on the sailboat is shown in

FIGS. 2 and 3

. In this type of construction, the track comprises an elongated strip


22


of metal or other suitable material, with grooves


24


being formed in opposite side edges of the track. The track is mounted over a slot


25


in mast


12


by means of screws


27


that extend through slot


25


into threaded contact with nuts


29


positioned on the inner side of the mast. Wheels or slides attached to spaced connectors along the edge of the sail ride in grooves


24


and hold the edge of the sail on the track. The accumulation of dirt and grime on the sail connector contact surfaces, such as in grooves


24


, is the primary problem addressed by the present invention. These grooves are cleaned effectively by means of the track cleaner


26


of the present invention. The particular grooved track described herein is for exemplary purposes. The invention can be used with other types and shapes of tracks.




Track cleaner


26


comprises a U-shaped housing


28


having spaced sides


30


, a back


32


, and an open front side


33


. The housing is formed of metal or other suitable material. Forward ends


35


of sides


30


of the housing fit over the grooves


24


in the outer edges of the track.




Adjustable cleaner members


34


are mounted adjacent ends


35


of the housing


28


. In the preferred practice of the present invention, there are two cleaner elements spaced longitudinally along the housing.




Each cleaner element includes a threaded shaft


36


that extends through a threaded opening


38


in side


30


, with a lock nut


40


serving to lock the shaft in any desired axial position. A knob


42


on the shaft is grasped for rotation of the shaft. A head piece


44


having a nose


46


thereon is threaded on the end of shaft


36


. Nose


46


has a domed shape that is positioned to fit into the opposed groove


24


in track


22


. Rotation of the knobs


42


bring the noses of the cleaners into juxtaposition with the grooves in the track. An abrasive material


45


, such as a pad of material sold commercially as “Scotch Brite”, is positioned between nose


46


and groove


24


and then the cleaner elements are moved into a light compressive or abrasive contact with the grooves in the track. The two spaced cleaner elements on each side of the housing hold the housing in vertical alignment with the track as the housing is moved upwardly and downwardly and prevent the housing from skewing into a binding position in the track.




The track cleaner elements


34


are further maintained in proper alignment with the grooves in the track by means of an adjustable spacer mechanism


50


mounted on the back of the channel. The adjustable spacer mechanism includes at least one threaded shaft


52


that extends through a threaded opening


54


in the back of the channel. The shaft terminates in a wheel support


56


positioned at the end of shaft


52


. The wheel support supports one or more wheels


58


on axles


60


. The wheels are positioned in alignment with the outer surface


62


of the track and are designed to ride along the outer surface. Rotation of knob


64


on the outer end of shaft


52


causes the wheel support and attached wheel to be moved toward and away from the track in order to properly position the housing and track cleaner elements with respect to the track and the grooves in the track. As shown in

FIG. 4

, the wheel support


56


can be an elongated channel member wherein the axles extend across sides of the channel member. The wheel support


56


can be supported on a pair of shafts


52


that are longitudinally spaced along the back of the housing. By using a pair of support shafts


52


, the proper vertical alignment of the wheel support


56


can be adjusted and maintained more effectively.




With the apparatus of the present invention, the track cleaner housing can be adjusted as desired to fit on any particular sailboat track and the elongated housing will be maintained in proper vertical alignment by the spaced track cleaners on each side of the housing and the spacer mechanism on the back of the housing.




In operation, the track cleaner is raised and lowered on the track of a mast as shown in FIG.


1


. The end of halyard


18


is clipped on an eye bolt


70


at the top of the housing


28


, and a downhaul line


72


is attached to an eye bolt


74


at a lower end of housing


28


. A person


76


can then raise the track cleaner up the track by pulling on the halyard, as shown in

FIG. 1

, and then he can lower the track cleaner on the track by pulling downhaul


72


downward. This action can be repeated until the track is cleaned and buffed as desired. The clean track will let the wheels or slide of the sail connector travel smoothly upwardly and downwardly along the track without the use of dirt collecting lubricants.




It should be understood that various modifications of the arrangements and details of construction of the present invention may be made without departing from the spirit and scope of the present invention.
