Abstract

A rigid foamed synthetic plastic in a generally spherical shape is provided with a groove around its entire periphery fixedly receiving one end of a line having its intermediate portion generally uniformly wound within the groove. The wound line is covered and securely held within the groove by means of one or more encircling resilient bands, with the opposite end of the line extending between the bands or from underneath one band to its connection with a weight. When marking a spot in the water, the weight will pull the line from beneath the rubber band or bands, which act as an unwinding brake, until the weight strikes the bottom of the body of water with the foamed plastic sphere floating on top of the water; thereafter, the band will resist or prevent further unwinding of the line. To prevent unwinding of the line, a second resilient band may be provided in a plane perpendicular to and encircling the first band. Tabs on the bands will facilitate their removal, when desired.

OConnor Attorney, Agent, or Firm-Charles W. l-lelzer 5 7] ABSTRACT A rigid foamed synthetic plastic in a generally spherical shape is provided with a groove around its entire periphery fixedly receiving one end of a line having its intermediate portion generally uniformly wound within the groove. The wound line is covered and securely held within the groove by means of one or more encircling resilient bands, with the opposite end of the line extending between the bands or from underneath one band to its connection with a weight. When marking a spot in the water, the weight will pull the line from beneath the rubber band or bands, which act as an unwinding brake, until the weight strikes the bottom of the body of water with the foamed plastic sphere floating on top of the water; thereafter, the band will resist or prevent further unwinding of the line. To prevent unwinding of the line, a second resilient band may be provided in a plane perpendicular to and encircling the first band. Tabs on the bands will facilitate their removal, when desired.
10 Claims, 4 Drawing Figures MARKING FLOAT BACKGROUND OF THE INVENTION Braking devices are known to control the unwinding of a weighted line wound about a float, for marking purposes. However, such tensioning devices or breaking devices are usually quite complicated, expensive, or constructed of cheaper materials that may be easily fouled with corrosion and the like.
It is desirable to mark a particular spot in open water for many reasons. It may be desirable to mark the location of fish, when a strike occurs while drift fishing, trolling, or still fishing. Further, a temporary ski course may be set up with such markers. Warning markers may be set up by scuba divers to show their presence, or warning markers may be set up for dangerous areas in lakes, streams and other bodies of water. Further, there are many accidents where equipment is lost overboard, and it is desirable to immediately mark the loca- SUMMARY OF THE DISCLOSURE The main body of the marker is generally of a spherical shape and preferably constructed of rigid foamed synthetic plastic, for example polystyrene. Also, the body may be constructed of a hollow rigid or semi-rigid plastic shell, for example which may be polyethylene formed in a centrifugal mold.
An annular groove is formed around the periphery of the body, preferably in a plane that passes through the center of the sphere. One end of a suitable line of appropriate length is secured, preferably by tieing, within the groove so that the line may be wound about the groove in successive layers by hand or machine. The opposite end of the line is provided with a weight, which may be of the lead weight fishing type. To prevent the undesired unwinding of the line and to control the unwinding of the line when in use, a braking device is formed by one or more resilient, preferably rubber, bands encircling the wound line and generally closing the outer portion of the groove. When two rubber bands are employed, the line is preferably fed between the rubber bands for attachment to the weight.
To prevent unwinding of the line, for example when the device is being stored, it is desirable to provide a second resilient, preferably rubber, band encircling the body, first band and wound line, and within a plane through the center of the spherical body and perpendicular to the first mentioned plane.
' When the device is to be used, the locking or second band is removed, with the aid of integral gripping tabs on the exterior of the rubber bands. When the device is thrown into the water, the weight will sink to the bottom of the body of water, provided the line is long enough, with unwinding of the line being tensioned and controlled by the rubber band or bands, which will allow unwinding of only enough line to allow the body to float on the top of the water and the weight to engage the bottom of the body of water, with allowance for deflection caused by currents and the like. When the device is retrieved, the rubber band within the groove may be removed, with the aid of the integral tabs, to facilitate the rewinding of the line within the groove; after this, the bands may be replaced.
BRIEF DESCRIPTION OF THE DRAWING Further objects, features and advantages of the present invention will become more clear from the following detailed description of the drawing, wherein:
FIG. 1 is a perspective view of a preferred embodiment of the present invention;
FIG. 2 is a partial view of the marker body of FIG. 1;
FIG. 3 is a view similar to FIG. 2, but of a modified construction for the marker body; and
FIG. 4 is a cross sectional view of a modified form of band tensioning device usable with the body of FIGS. 2 or 3.
DETAILED DESCRIPTION OF THE DRAWING As shown in FIG. 1, a preferred embodiment of the floating marker of the present invention is shown in perspective in its storage condition, immediately prior to use.
The body 10 or float portion of the marker is generally spherical in shape and constructed preferably of a rigid foamed synthetic plastic, for example foam polystyrene. However, the body may also be constructed of a dense plastic material of generally uniform wall construction forming a hollow shell, which would be water tight. The shell may be formed by centrifugal molding of a synthetic plastic, for example polyethylene. Further, the exterior surface of the body may be brightly colored by coating or coloring the material from which it is molded so that it may be readily seen while floating upon the water. As aspecific example, the body may be approximately 6 inches in diameter.
With reference to FIGS. 1 and 2, the body 10 is provided with a groove 11, which extends around the entire periphery of the spherical body 10, preferably in a plane that passes through the center of the spherical body. The groove is formed by a recess within the body defined by a cylindrical bottom surface 12, and side walls l3, 14. The side walls are oppositely angled and preferably form an angle of 45 with the abovementioned plane. As a specific example, the width of the groove may be three-fourth inches with one-fourth inch depth, or most preferably of a width one-half inch and with a three-eighth inch depth.
The weighted line is attached and wound within the groove. The inner end of the line is preferably wrapped once around the groove and knotted so that it is securely held in position. Thereafter, most of the remaining portion of the line 15 is wound around the body 10 within the groove 11 in overlying layers 16. This tieing and winding may be manually accomplished or performed with machines. The outermost end of the line 15 will extend from the groove 11 and is secured, preferably by tieing, to a weight 17. Most preferably, the weight 17 is constructed of lead and generally of the type employed in fishing.
To control the unwinding of the line 15, when unwinding is desired, and to generally prevent unintentional unwinding of the line 15 from the groove 11, a single flat rubber band 18 is employed in the embodiment of FIG. 1 to substantially completely overlie the bottom surface 12 of the groove 11 to clamp therebetween the line winding 16. The band 18 is resilient, and preferably it is constructed of natural or synthetic rubber. Suitable tabs 19, two being shown, are provided on the band 18 to assist in gripping the band 18, preferably for its removal. The tabs 19 may be homogeneously formed with the band 18.
Further as shown in FIG. 1, a second band 20 may be provided generally in a plane passing through the center of the spherical body and perpendicular to the first mentioned plane of the band 18 to encircle the body 10, the band 18, and the winding 16 of line 15. Thus, the band 20 functions as a locking device to prevent unwinding of the line 15. It is desirable to employ the band 20 during storage of the marking device, and the band 20 is removed prior to using the marker. Preferably, the band 20 is identical in structure to the band 18 to reduce manufacturing costs, although it may take on many different forms. Tabs 21 are provided on the band 20 to assist in its removal. To retain the band 20 in its desired position, the body 10 is provided with two diametrically opposed notches 22, 23 to receive diametrically opposed portions of the band 20.
The groove structure 11 of the preferred embodiment according to FIG. 1 may be modified as shown at 11' in FIG. 3, by providing the bottom surface 12' of the groove generally coextensive with the major outer portion of the body surface, with the groove side walls 13', 14', being formed by upstanding annular ridges. This groove construction may be used for the foam plastic body, although it is particularly well suited to the shell construction. Otherwise, the embodiment of FIG. 3 is identical to the body construction of FIG. 1.
With either the body construction of FIG. 2 or FIG. 3, FIG. 2 being employed as an example, the band 18 may be replaced by two bands 24, 25, as shown in FIG. 4. Otherwise, the construction of the embodiment partially shown in FIG. 4 would be identical to that of FIG. 1, except with the possibility of modification as shown in FIG. 3. With the employment of two rubber bands 24, 25 that overlie the line winding 16, the line would be fed between the rubber bands as shown in FIG. 4 for connection to the weight, not shown. Further, it is contemplated that the bands 24, 25 may be wider than shown so that they will overlap each other to further grip the line as it is being unwound. Each of the rubber bands 24, 25, which are separate, may be provided with one or more tabs, such as shown at 19 in FIG. 1.
OPERATION Although the operation will be described with respect to the embodiment of FIG. 1, it is to be understood that the operation is substantially the same for all of the modifications, with the exceptions previously noted.
When it is desired to mark a particular location in a body of water for the reasons previously mentioned, the marking device of FIG. 1 is removed from storage and the band 20 is removed from the body 10, with the assistance of the integral tabs 21 that are grasped between the fingers. Thereafter, the remaining portion of the device may simply be thrown into the water. Thereafter, the weight 17 will pull the line from beneath the tensioning or braking band 18 as the body 10 floats or spins on the top of the water. In this manner, the band 18 will control the unwinding of the line until the weight 17 strikes the bottom of the body of water, provided that sufficient line has been provided for the particular depth. Thereafter, further unwinding of the line will be prevented or greatly limited by the braking action of the band 18. If the device is subsequently retrieved, the band 18 may be removed, with the assist ance of the tabs 19, and the line 15 reqwound within the groove 11. Thereafter, the band 20, with the assistance of the tabs 21, may be replaced and the marking device is ready to be returned to storage.
While a preferred embodiment of the present invention, with variations, has been specifically described above with the specific details being of advantage, further modifications, embodiments, and variations according to the broader aspects of the present invention are contemplated as defined by the spirit and scope of the following claims.
