Abstract
A marker buoy is provided for use with a flexible line tied to a weighted sinker. The buoy includes a watertight, transparent dome assembly with an interior light source positioned therein. The dome assembly resides on a buoyant housing with a bottom aperture and line guide for receiving and guiding a flexible line for winding on a reel assembly positioned within the housing. The reel assembly utilizes a spiral coil spring that is wound as the line unwinds from the spool and acts to return excess line to the spool as the sinker attached to the line comes to rest on its intended submerged surface. In one embodiment a reduction gear is provided to increase the number of spool turns available before the spring winds completely.

A marker device for fishermen including a body or flotation portion made from a transparent, plastic bottle. A sheet of brightly colored fluorescent or retroreflective paper lines the inside of the bottle, making the marker highly visible. A threaded cap is secured to the core or bottom end of a spool, about which an anchor line is wound. The spool has upper and lower flanges, and the anchor line is secured to the upper flange. An anchor weight is secured to the free end of the anchor line, the anchor weight being a strip of malleable lead that may be formed to bend around the anchor line wound on the spool when not in use. Further, a counterweight is contained within the bottom portion of the spool opposite the bottle, causing the marker to stand upright in the water. After the marker has been set in the water and the anchor weight has sunk to the bottom of the lake or stream, the anchor line may be threaded through a slot in the lower flange of the spool, preventing additional anchor line from being paid out from the spool.

A marker for use by boaters to mark spots in a body of water includes a watertight, hollow cylindrical main body that floats and which serves as a buoy member. The main body is capped at its opposite ends by end caps that are apertured. An elongate hollow tube is positioned within the hollow interior of the cylindrical main body so that it extends between the apertures. A spool member having a preselected length of line coiled thereabout is rotatably mounted atop the upper end cap and line extends from the spool through the interior of the hollow tube to the bottom of the body of water when the marker is in use, there being a weight at the free end of the line. Beads of progressively larger size relative to the free end of the line are secured to the line, each bead being positioned at a preselected length of the line that represents a particular water depth. A slide plate is slidably mounted to the bottom end cap in alignment with the hollow interior of the tube and bores of differing sizes are formed in the slide plate, each size corresponding to a bead and being slightly smaller than its corresponding bead to prevent its passage through the slide plate. The user aligns a preselected bore, representing a known water depth, with the hollow interior of the tube and unreels the line until a bead is stopped from passing through its associated bore.

A highly visible container protected polyurethane foam flotation buoy, with a transparent polycarbonate housing enclosing a plastic line spool which is supported by a stainless steel axle which has a stainless steel rewind handle, with nylon roller, and a adjustable nylon brake assembly. Housing is secured to bottom of flotation buoy, housing assembly and spool assembly which are used in the deployment and take up of anchor and anchor line comprises complete flotation unit. Anchor is a five pound steel core enclosed in PVC with a stainless steel connection bolt. In use anchor will have descended to bottom and buoy will be on top surface of water connected by anchor line and will not drift off marked spot.




While these marker buoys may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described. It is thus desirable to provide a multi-purpose flotation buoy device.




SUMMARY OF THE PRESENT INVENTION




A primary object of the present invention is to provide a marker buoy constructed of material highly resistant to rust and corrosion, thereby giving the marker buoy a long life in a harsh marine environment.




Another object of the present invention is to provide a marker buoy having a reel assembly with a coil spring, line spool and crank handle.




Yet another object of the present invention is to provide a marker buoy consisting of a coil spring to maintain line tension providing a more accurate marking of the area by regulating the extension and retraction of excess line.




Still yet another object of the present invention is to provide a marker buoy having a clear dome compartment for inserting a glow stick therein.




Yet another object of the present invention is to provide a marker buoy that is easy to operate and use, constructed of material highly resistant to rust and corrosion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,

FIGS. 1-90

illustrate the Marker Buoy of the present invention, indicated generally by the numerals


10


.




The Marker Buoy


10


is shown generally in

FIGS. 1-9

and in use in the water


12


in

FIGS. 1 and 7

. In the usage shown, the device


10


is equipped with a flexible line


14


and a sinker


16


.




As shown in

FIGS. 2-6

and


8


-


9


, the device


10


has a housing


20


that is generally cylindrical, having an opening


22


for the line


14


. The line is guided from the housing


20


by a small diameter cylindrical portion


24


. The housing


20


is constructed from polyurethane foam. Additional housing structure and buoyancy is provided by a flotation ring


26


integrated with the top of the housing


20


. The ring


26


has an aperture


28


that allows hand access into the housing


20


.




A threaded upper portion


30


extends from the ring


26


, and this upper portion is sized to closely receive a buoy access cover


32


. A transparent dome


34


has threads


36


for mating with the threaded upper portion


30


providing a water-tight enclosure bounded by the dome


34


and the top of the buoy access cover


32


.




As shown in

FIG. 3

, a glow stick tube


37


with a cap


38


is centrally disposed upon, and extends upwardly from, the top surface of the buoy access cover


32


. A glow stick


39


is insertable within the tube and is chemiluminescent. Due to the glow stick's


39


positioning under the transparent dome


34


, the glow stick


39


is highly visible under low light conditions. In other embodiments, a battery or solar powered light source, or other light sources can be substituted, all in accordance with the present invention, as will occur to those of skill in the art upon review of the present disclosure.




A reel assembly


40


is positioned within the housing


20


, with a shaft


42


having a first end


44


protruding through an aperture


46


in the side of the housing


20


. A handle


52


is attached to the shaft first end


44


for hand rotation of the shaft


42


.




As shown in

FIG. 6

, a spool


54


is joined to the shaft


42


at the shaft second end


48


. The spool


54


rotatably joins the housing


20


at a housing spool post


50


for convenient winding and unwinding of the flexible line


14


by hand-rotation of the shaft


42


using the handle


52


.




Positioned on the spool


54


is a reduction gear


56


. The reduction gear


56


is mated to a larger spring gear


58


, such that rotation of the shaft


42


rotates the reduction gear


56


, which in turn rotates the spring gear


58


. A spiral coil spring


60


has a first end


62


attached to the housing


20


at a housing spring post


64


that extends from the housing


20


. The spring


60


has a second end


66


that is joined to the spring gear


58


by an attachment member


68


. As the spring gear


58


is rotated the spring second end


64


is rotated such that the coil spring


58


is either wound or unwound, depending on the direction that the handle


52


is turned. The reduction gear


56


causes a significant increase in the number of turns of the spool


54


before the spring


60


is completely wound and further spool


54


rotations are prevented.




The spring


60


is normally unwound when the line


14


is fully wound on the spool


52


. Although wound and in tension when the line


14


is unwound from the spool


52


, the spring


60


force is not sufficient to cause the device


10


to be pulled under the water


12


surface. The force is sufficient, however, to reduce or eliminate the lateral movement of the device


10


from its normal position directly above the spot marked by the sinker


16


, and to return the device


10


to such a position after the current or waves that laterally displaced the device


10


subside. To accommodate a variety of water depths, the user can attach or include additional line


14


beyond the spool


54


and spring


60


effective capacity, and leave as much line


14


as necessary before tying the line


14


to the sinker


16


, allowing excess line


14


to trail off from the sinker


16


.




In another embodiment, the coil spring is attached directly to the spool for direct rotation, with the coil spring first end attached to the housing spool post.




The device


10


and its foregoing components can be constructed using various materials, including various buoyant materials such as plastic foam, foamed polyethylene, closed cell plastic foam, styrofoam and foam rubber, and can also include fluorescent and phosphorescent materials. The reel assembly


40


components can be made from various corrosion-resistant materials, such as stainless steel and various plastics. All such material combinations and selections are in accordance with the present invention, as will occur to those of skill in the art upon review of the present disclosure.




It will be understood that each of the elements described above, or two or more together may also find a useful application in other applications differing from that described above.




While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.




Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
