Abstract:
An improved anchor ( 20 ) for securing the floatation units ( 12 ) of marker buoys ( 10 ), waterfowl decoys ( 36 ), and the like at selected locations on a body of water. The anchor ( 20 ) has an anchor weight ( 24 ) portion of non-lead material and a pair of clamping arms ( 30 ) extending outwardly from the anchor body ( 22 ), and configured and adapted to springably spread apart to open, to close about, and to releasably clamp onto the floatation unit ( 12 ), thus preventing the release and tangling of anchor line ( 14 ). This provides convenient storage for the marker buoy ( 10 ) or the waterfowl decoy ( 36 ) with its wound anchor line ( 14 ) and the attached anchor ( 20 ). Currently, marker buoy anchors and waterfowl decoy anchors frequently consist of a thin lead strip capable of being bent around a portion of the floatation unit ( 12 ) of the marker buoy ( 10 ) or the waterfowl decoy ( 36 ) for secure storage. For use, the lead strip can be unbent to release it from the floatation unit ( 12 ). My present invention is uncomplicated, easy to use, and easy to manufacture. It provides a superior alternative to the current technique of using bendable lead anchors, thus eliminating the need for this particular use of lead, a potential source of pollution.

     FIELD OF THE INVENTION 
     This invention relates generally to the weighted anchors used with marker buoys by fisherman and boaters to mark particular selected locations, and by hunters to anchor buoyant waterfowl decoys on a body of water. 
     BACKGROUND OF THE INVENTION 
     Weighted anchors are frequently employed by fishermen, boaters and others to maintain positioning of floating marker buoys used to mark underwater objects or selected locations on the surface of a body of water. Similar sized weighted anchors are also often employed by waterfowl hunters to tether their floating decoys at selected locations on the water surface. 
     Marker buoy anchors can be used to mark fishing areas, navigation routes, and underwater points of interest. Marker buoys in general use often consist of a floatation unit connected to one end of an anchor line, with the other end of the anchor line tied to a weighted anchor. In use, the marker buoy and the anchor are tossed or placed onto the water surface, and the anchor line pays out as the anchor descends to the bottom of the water body. 
     The anchors of currently available marker units are typically of a homogeneous material with high specific gravity such as lead or steel. Steel anchors are often U-shaped to allow them to be conveniently placed over the wound line on the anchor line spool of the floatation unit for compact and tangle-free storage. Lead anchors have a slightly higher specific gravity than steel, but their primary advantage over steel is their malleable quality. When shaped as a rectangular strip, these anchors can be manually bent and formed around the anchor line spool or other part of a marker buoy for neat and secure storage. They stay in place on the floatation unit and prevent the anchor line from unwinding or getting tangled. To be disengaged from the floatation unit for use, they are easily unbent to free them. 
     U.S. Pat. No. 4,443,203 issued to Maertens on Apr. 17, 1984; U.S. Pat. No. 4,501,563 issued to Johnson et al. on Feb. 26, 1985; U.S. Pat. No. 4,544,364 issued to Bankston on Oct. 1, 1985; and U.S. Pat. No. 5,188,551 issued to Keller on Feb. 23, 1993, all disclose examples of anchors composed of bendable lead so that they can be formed around the marker body for storage when not in use. They all have one major disadvantage. Lead is a serious pollutant. Lead shot used in shotgun loads is being replaced by shot made of steel, bismuth, and other materials. Lead bullets sometimes fragment and cause problems when ingested by birds and animals. In recent years, efforts have begun to replace lead fishing sinkers with steel sinkers. When a marker buoy is in use, the anchor line can be accidentally severed, severed from abrasion, or severed after deterioration over time. When this occurs, the anchor is likely to be abandoned on the bottom of the water body constituting a pollutant. If the marker buoy with its lead anchor eventually ends up in a landfill, the lead can be a pollutant there also. 
     Steel, while considered much less of a pollutant, is less frequently used as an anchor material, because it doesn&#39;t have the malleability to be easily bent around the marker buoy to clamp onto the marker buoy to prevent tangling of the anchor line when it is not being used. 
     Decoy anchors are used by waterfowl hunters to keep their floating decoys at the selected locations and in the pattern of which they were positioned on the water surface. Floating waterfowl anchors usually have a length of cord attached to their keel at one end, and an anchor attached at the other end. When not being used, these decoys are typically stored with the anchor cord wound around the decoy or its keel, and with the anchor secured to some portion of the decoy or its keel. Often the anchor is a thin lead strip that can be bent around the neck or keel of the decoy to hold it in place for storage. But the repeated bending and unbending can cause the lead anchor to break. Lead anchors also have the disadvantage of being a serious pollutant. With the large number of decoys employed by many hunters and frequent broken anchor lines, many of these lead anchors may not be recovered from the bottom of the water body. 
     To use the decoy, the anchor is disengaged from the decoy body, and the anchor and decoy are tossed or placed onto the water surface. The anchor, which is attached to the decoy by a fixed length of decoy cord, sinks to the bottom, thus preventing the decoy from drifting very far from its initial position on the water surface. A small amount of slack is usually provided in the decoy cord to allow the decoy to move in a life-like manner. 
     Decoy anchors are generally made of high specific gravity materials such as lead or steel. An essential feature of decoy anchors is that they must function in combination with their attached decoys to be tangle-free while in use, while in transport, and while in storage. 
     Decoy anchors are often used and stored in large quantities, and tangling of the anchors and cords is a particularly annoying and bothersome problem. Decoys are often set out or retrieved in the dark, and sometimes during cold weather. These adverse conditions tend to exacerbate the difficulty if cords and anchors get intertwined or tangled. Another problem occurs with loose fitting anchors or with anchors that become separated from their attachment point on the decoy. These loose anchors can strike the decoys and damage their finishes. 
     Over many years, waterfowl hunters and other practitioners have devised and revised various methods and decoy/anchor arrangements to minimize the potential for tangling. Most of these methods involve winding the anchor cord around the body or keel of the decoy, and then securing the anchor to some part of the decoy. Some designs include reels to deploy and retrieve the anchor cord. Malleable lead shapes have very often been used for decoy anchors, because thin lead can be bent and formed around the neck, bill, or keel of the decoy when not in use. When steel anchors have been used, they have often been configured to fit over the neck of the decoy, or they may be secured by an elastic band or other means to the keel of the decoy. 
     U.S. Pat. No. 5,461,816 issued to Gazalski on Oct. 31, 1995; U.S. Pat. No. 5,899,014 issued to Bornhoft et al. on May 4, 1999; U.S. Pat. No. 6,543,176 issued to McGhghy on Apr. 8, 2003; and U.S. Pat. No. 6,857,216 issued to Merin on Feb. 22, 2005, all disclose anchors designed to prevent anchor line tangling when used for waterfowl decoys. 
     The Gazalski anchor is plastic and filed with shot, sand, water and sand or other materials. The anchor slides onto the keel of the decoy for storage, but the keel must be shaped and adapted uniquely to receive and grip this anchor. The decoy keel and the anchor must be designed to fit in combination. Thus, this anchor would not likely fit or be properly secured with most existing decoys. 
     The Bornhoft et al. anchor has a clasp of deformable resilient material to grip the anchor cord after the cord is wound onto to decoy for storage. The clasp must be manually manipulated to slip onto the cord and is subject to slippage and degradation over time and use. 
     The McGhghy anchor has a bail, and the anchor cord is wrapped around this bail for storage. The bail end of the anchor attaches to one end of the decoy keel, and there is a stretchable band used to attach the other end of the anchor to the other end of the decoy keel. The keel of the decoy must have a notch at both ends, one notch for the bail and the other for the stretchable band. The stretchable band is a separate article that can easily become lost, and it can deteriorate with time and use. This anchor must also be matched with a particular keel configuration having the two notches to function properly. Thus, the anchor and keel must be designed in combination to fit properly. Also, having to wind the anchor cord around the bail, and using the separate stretchable band for each decoy would be somewhat time consuming if one were using a large number of decoys. 
     The Merin anchor cord is wrapped around the decoy keel. It has a stretchable latex tube to facilitate securing the anchor to the decoy. During storage the ball shaped anchor fits in a slot between the decoy and its keel at the rearward end of the decoy/keel. Again, the design of the decoy/keel interconnection must be configured to fit this specific ball-shaped anchor. 
     BRIEF SUMMARY OF THE INVENTION 
     The objects of the invention are: 
     (a) Provide a durable anchor for marker buoys, waterfowl decoys, and the like that is uncomplicated, easy to use, and easy to manufacture. 
     (b) Provide an anchor that is of high specific gravity and is of sufficient weight to facilitate the operation of the anchor but does not contain a significant amount of lead. 
     (c) Provide an anchor of streamline shape so that it does not collect soil, weeds, and other debris when in use. 
     (d) Provide an anchor that has the capability to releasably clamp and hold onto the floatation unit of a marker buoy or waterfowl decoy for secure storage and to prevent the unwinding and tangling of the anchor line when it is not being used. There is a need for a non-lead anchor for marker buoys, waterfowl decoys, and the like, having the capability of releasably clamping and holding onto the marker buoy or waterfowl decoy when the anchor is not being used.
 
(e) Provide an anchor that the user can easily release from its storage position on the marker buoy or waterfowl decoy for use.
 
     This invention is an anchor for use with a marker buoy, waterfowl decoy, or the like. It is of a generally U-shaped configuration having a weighted portion and two outwardly extending, opposed, springable arms shaped and adapted to clamp and hold onto the floatation unit of a marker buoy or waterfowl decoy to prevent the release and tangling of anchor line, and for convenient storage when not in use. In order to provide proper operation, the anchor is composed substantially of high specific gravity material and is of sufficient weight to hold the floatation unit of a marker buoy or waterfowl decoy at a location nearly directly above the anchor, despite the action of wind, waves, or currents. This anchor is of non-lead material and does not rely on the malleable characteristic of lead to be bent and formed around a portion of the floatation unit of a marker buoy or waterfowl decoy when not in use. This eliminates the use of lead, a commonly used material for marker buoy and decoy anchors, and a potential source of pollution. 
     The advantages of the invention are: 
     (a) This anchor is quite simple and easy to manufacture and use. 
     (b) Currently available anchors are often made of thin leads strips such that they can be easily bent and formed around some portion of a marker buoy or decoy for secure, tangle-free storage. However the anchor of this invention can be made of corrosion-resistant steel. It does not rely on the use of malleable lead, a serious pollutant, to be formed around a portion of the floatation unit of a marker buoy or decoy.
 
(c) This anchor has the capability to releasably clamp and hold onto the floatation unit of a marker buoy or decoy for secure storage, and to prevent the unwinding and tangling of the anchor line when it is not being used.
 
     These and other objects, features, aspects, and advantages of the invention will become more clearly understood from the following detailed description when read together with the claims and drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the drawings in detail wherein like numerals designate like parts, and with particular reference to  FIG. 1 , the first embodiment incorporating the concepts of the invention of an anchor, generally designated by reference numeral  20 , is shown in a perspective view. Anchor  20  of this invention is designed to be used with marker buoys, floating waterfowl decoys, and the like. 
     As illustrated in  FIG. 2 , an anchor line  14  is connected to one end of the floatation unit  12  of a marker buoy  10 , and at its other end to an anchor line connection member  34  at the base end or some other point of anchor  20 . Floatation unit  12  is the floating portion of a marker buoy, waterfowl decoy, or the like. Anchor line connection member  34  is composed of steel or other high strength material, shaped as an eye, ring, snap, or other effective means of providing a strong, secure attachment to anchor line  14  by using a knot or equivalent connection. Anchor  20  of this embodiment is of a modified u-shaped configuration with an enlarged anchor body  22  and a pair of spaced, opposed clamp members, gripping claws, or arms  30  extending outwardly from anchor body  22 . Anchor body  22 , with its two integral arms, has an outer shell cover  32 . Shell cover  32  is composed of flexible, abrasion-resistant material that can be repeatedly bent without degradation such as polyethylene-tere-phthalate, polypropylene, vinyl, nylon, hard rubber or other plasticized materials, and it contains segmented anchor weight  24 . 
       FIG. 3  is a perspective view of anchor  20  with a cut-away view showing segmented anchor weight  24  and at least one elongated stiffener  28  positioned inside of shell cover  32 . Segmented anchor weight  24  is composed of non-lead material having a specific gravity of at least 4.0, such as iron, steel, or mineral aggregate, and is of sufficient weight to confine floatation unit  12  to a small area on the water surface nearly directly above anchor  20  when anchor  20  is deployed at the bottom of the water body. Segmented anchor weight  24  comprises a plurality of individual anchor weight segments that are substantially rounded and have generally smooth surfaces to allow these individual anchor weight segments to easily slide against adjacent surfaces of one another for the purpose of allowing anchor  20  and arms  30  to easily flex. 
     Elongated stiffener  28  traverses through the interior of anchor body  22  and extends longitudinally through the interior of at least one-half of the length of arms  30 , and is composed of malleable steel, plastic, or other suitable material that can be easily and repeatedly manually bent and unbent without degradation. Elongated stiffener  28  has a cross-sectional configuration with sufficient stiffness to allow arms  30  to clamp and hold onto floatation unit  12  without easily becoming dislodged therefrom when not in use. Elongated stiffener  28  allows arms  30  to be easily and repeatedly bent to partially close together about floatation unit  12  to clamp and hold onto floatation unit  12  to prevent the inadvertent release and tangling of anchor line  14 , and to provide convenient storage of floatation unit  12 , anchor line  14 , and anchor  20  when not in use. Elongated stiffener  28  also allows arms  30  to be easily and repeatedly unbent to spread apart to release anchor  20  from floatation unit  12 . Arms  30  may be angled slightly outward from each other or they may have recurved tips to facilitate urging arms  30  apart when positioning anchor  20  onto floatation unit  12 . 
     When the user wants to use marker buoy  10  or waterfowl decoy  36  and anchor  20 , he or she grasps floatation unit  12  in one hand and grasps anchor body  22  in the other hand. Then he or she pulls anchor  20  outwardly away from floatation unit  12 , thus urging arms  30  and elongated stiffener  28  to bend and spread outwardly apart as arms  30  slide off from floatation unit  12 , resulting in the release of anchor  20  from floatation unit  12 . When arms  30  are free of floatation unit  12 , floatation unit  12  and anchor  20  are ready for deployment. This bending of elongated stiffener  28  and arms  30  is facilitated by the contained segmented anchor weight  24  being of segmented form, and the segments having sufficiently smooth surfaces to allow them to slide against each other as arms  30  flex. 
     The user can then place or toss floatation unit  12  and anchor  20  onto the water surface at a selected location. Gravity will cause anchor  20  to descend downwardly until anchor  20  reaches the bottom of the water body. Anchor  20 , being of sufficient weight, will then hold floatation unit  12  in close proximity to its selected position on the water surface despite the action of wind, waves, or currents. 
     When the user wants to discontinue use and return anchor  20  to its storage position on floatation unit  12 , he or she retrieves floatation unit  12  and rewinds anchor line  14  thereon. Then the user grasps floatation unit  12  in one hand and grasps anchor body  22  in the other hand and pushes the two outward ends of arms  30  against opposite sides of the attachment point of floatation unit  12 . With arms  30  being in the outwardly bent position, arms  30  easily slide over the opposite sides of the attachment point of floatation unit  12 . When arms  30  are in position, the user manually bends arms  30  along with elongated stiffener  28  back to the substantially closed position, closing about, loosely gripping, and holding onto floatation unit  12 , thus preventing the inadvertent release and tangling of anchor line  14 . This provides a convenient and secure storage arrangement for floatation unit  12  with its wound anchor line  14  and its attached anchor  20 . 
       FIG. 5  and  FIG. 6  depict a second embodiment of the invention. In this embodiment, it can be seen that segmented anchor weight  24  is, again, composed of non-lead material comprising a plurality of individual anchor weight segments as described for the first embodiment. Elongated stiffener  28  is replaced with at least one spring  26 . Spring  26  can be of similar configuration to that of elongated stiffener  28 , but is of flexibly resilient material such as spring steel or resilient plastic material. Spring  26  can be configured as a leaf spring, bar-shaped, or circular in cross-section. Spring  26  is configured to facilitate the two arms  30  to be easily and repeatedly flexed to partially close together about the attachment point of floatation unit  12  to clamp and hold onto floatation unit  12  when not in use. Spring  26  also allows arms  30  to be easily and repeatedly flexed to springably spread apart to release anchor  20  from floatation unit  12 . 
     When the user wants to use marker buoy  10  or waterfowl decoy  36  and anchor  20 , he or she pulls anchor  20  outwardly away from floatation unit  12 , thus causing arms  30  to slide over the opposite sides of the attachment point of floatation unit  12  to release anchor  20  therefrom. The user can then deploy floatation unit  12  and anchor  20  by tossing or placing them onto the water surface. 
     When the user wants to discontinue use and return anchor  20  to its storage position on floatation unit  12 , he or she rewinds anchor line  14  onto floatation unit  12 . Then the user pushes the two ends of arms  30  against opposite sides of the attachment point of floatation unit  12  causing arms  30  to springably spread apart to allow arms  30  to slide onto floatation unit  12 . The closing force of spring  26  then causes arms  30  to return to their original configuration, partially closing about, loosely gripping, and holding onto floatation unit  12 . 
       FIG. 7  and  FIG. 8  depict a third embodiment of the invention. In this embodiment, segmented anchor weight  24  is, again, composed of non-lead material in segmented form as described for the first and second embodiments. The spring  26  of the second embodiment is absent, but the shell cover  32  is, itself, of flexibly resilient material to act as a spring. Anchor  20 , with its integral arms  30 , is therefore springably capable of releasably clamping and holding onto floatation unit  12 . The material of shell cover  32  of this third embodiment can be of hard rubber, neoprene, or resilient plastic material to allow arms  30  to releasably clamp and hold onto floatation unit  12  when not in use. Except for the spring function, the second and third embodiments and their use are identical. 
       FIG. 9 ,  FIG. 10 , and  FIG. 11  depict a fourth embodiment of the invention. In this embodiment, the anchor body consists of a spring  26  or a similarly shaped member powered by a coil spring (not shown). Spring  26  is of spring steel, resilient plastic, hard rubber, or other suitable flexibly resilient material capable of acting as a spring to releasably clamp and hold onto floatation unit  12 . One or two non-lead elements of integral anchor weight  25  are fixedly attached to one or both of the arms  30 . Integral anchor weight  25  can be attached to arm  30  by welding, metal fasteners, or other means of fixed permanent attachment. This embodiment of the invention does not require a shell cover  32 , but may include a protective coating of flexible, abrasion-resistant plastic or other similar material. Arms  30  and spring  26  are integrally formed. Other aspects of this embodiment and its use are as described for the three previously described embodiments of the invention. 
       FIG. 12 ,  FIG. 13 ,  FIG. 14 ,  FIG. 15 , and  FIG. 16  illustrate a fifth embodiment of the invention. In this embodiment, a resilient spring  26  is, again, included in the arms  30 , and the non-lead integral anchor weight  25  is attached at the rearward end of the anchor  20 . Spring  26  and integral anchor weight  25  are enclosed within a shell cover  32 . Shell cover  32  is integrally formed with the two arms  30 . In this embodiment, integral anchor weight  25  can be a single element. Spring  26  is as described for the second embodiment but can be of a slightly different configuration as shown. It should be understood that, in a variation of this embodiment, spring  26  can be absent (not shown absent in drawings) if arms  30  are, themselves, composed of flexibly resilient material capable of springably clamping and holding onto floatation unit  12 . Other aspects of this embodiment and its use are as described for the previously described embodiments of this invention. 
       FIG. 16  Shows the fifth embodiment of anchor  20  of the invention releasably clamped onto the floatation unit  12  of a typical waterfowl decoy  36  in the storage position. Anchor  20 , when used with waterfowl decoy  36 , is of the same design as for use with marker buoy  10 . The operation and use of anchor  20  are also the same for both marker buoy  10  and waterfowl decoy  36 . 
     CONCLUSION 
     Marker buoy anchors and waterfowl decoy anchors are sometimes made of steel, but steel is rigid and does not allow the anchor to be easily bent and formed around a portion of the floatation unit of a marker buoy or waterfowl decoy to securely grip the marker buoy or decoy when not in use. This can often result is loose and tangled anchor line. Because it is easily bendable, lead is commonly used for marker buoy anchors and waterfowl decoy anchors. It can be configured to be readily formed around a portion of the marker buoy or waterfowl decoy when not in use, to secure the anchor to the marker buoy or decoy. This malleable quality of lead provides for convenient storage, and effectively prevents the unwanted release and tangling of anchor line. 
     While lead has this advantage over currently available steel anchors, lead is increasingly recognized as a serious pollutant of our land, water, and air. There is, therefore, a need for a non-lead anchor with the capability of clamping and holding onto the marker buoy or decoy when not in use. The reader can see that the various embodiments of this invention provide such an anchor that has the advantages of currently used lead anchors but do not require the use of lead. 
     While the above description contains many specifications, these should not be construed as limitations on the scope of the invention, but rather an exemplification of certain embodiments thereof. The embodiments described above merely illustrate principles of the invention and some possible variations in form. Other variations are possible. For example, it should be understood that the size and configuration of the anchor of this invention might vary widely depending upon the size and configuration of the specific marker buoy or waterfowl decoy used therewith. Also, in the above-described appended drawings, the attachment point for the anchor is the line storage spool of a marker buoy or the keel of a waterfowl decoy. Depending upon the configuration of the marker buoy or decoy with which the anchor is to be used, other attachment points may be more suitable for attaching the anchor for storage. 
     Workers skilled in the art will recognize additions, deletions, and other modifications that can be made in form and detail without departing from the spirit and scope of this invention. Thus the scope of the invention should be determined by the appended claims, and not by the examples given.
