DETAILED DESCRIPTION

(8) In the following detailed description of embodiments of the invention, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to one of ordinary skill in the art that the invention may be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.

(9) Objects and Advantages

(10) An object of the invention is to provide an anchor that is equally effective regardless of the type of holding, whether that holding be sand, rock, coral, mud or the like.

(11) Another object of the invention is for anchoring a small boat or the like water-borne vessel at a given locale.

(12) Yet another objective of the invention is to provide an anchor especially suited for use with small fishing and pleasure craft whereby little strength is required to pull the anchor onboard after heaving a much heavier anchor off board.

(13) Another object of the invention is to provide and anchor effective regardless of the type of holding, whether that holding is sand, rock, coral, mud or the like.

(14) Yet another object of the invention is to create variable weight anchors, eliminating some of the inefficient structural weight associated with swing-type or fluke anchors.

(15) The present invention discloses several embodiments for making a variable weight boat anchor. Furthermore in an aspect of the invention, one or more flukes, with and without added matter storage cavities can be integrated with the anchor housing for containment of a releasable heavy weight substance. The weighting substance can be rocks, gravel, aggregate, sand and combinations of these.

(16) FIG. 1 illustrates a two line semi-hollow fluke variable weight boat anchor in an embodiment of the invention. In a two line embodiment there are two lines or ropes shown 101 102. An anchor drop line 101 is tied 103 attached to a rigid loop 105 at one end of the anchor body 107 and another line 102, the anchor pull line is tied attached to and opposite end of the anchor body, call it the bottom end. The line 102 attached to the opposite or bottom end of the anchor can be color coded at the boat end so an individual will know to pull on that end for pulling anchor for departure. An emptying mechanism employed in an embodiment of the invention when provide a tug or pull from a boat being anchored, the anchor housing base containing weighting matter will overturn to empty it contents of the loaded material as it is pulled to the boat. Proximate to bottom end 115 of the anchor body 107 are hollowed flukes 113 providing a kind of pocket 111 or volume along each fluke 113 as heavier than water weighting material 112 such as rocks, gravel, aggregate or sand can be stored to provide a securing weight. Upon pulling up anchor, the pull line 102 is lifted. The pulling line 102 can be color coded or of lesser line tension weight to differentiate its function, so that any loose heavy matter 112 contained in the anchor fluke 113 pockets are discarded submerged and a weight matter discarded lighter anchor is pulled up with less weight. The anchor body fluke 113 can have a partial covers 109 110 to reduce unwanted spillage if the anchor is dragged.

(17) An embodiment of a variable weight boat anchor has an anchor base 107 integral with a housing cavity for temporary storage of solid matter integrated with at least one anchor fluke 111, and the anchor base 107 rigidly coupled to at least one line attachment loop 105 for at least one boat line 101 102 secured to the anchor base housing 107 with the anchor base housing storage volume 111 providing a cavity or volume 113 integrated with a fluke 113. A boat anchor drop line 101 is attached to a mechanism to release or unload added weight matter 112 stored within the cavity or volume anchor housing volume 113 while submerged, and a mechanism for releasing stored matter 112 with the release mechanism integrated with a remotely operated trigger. Thus a trigger can emanate from an anchored boat set to release the added weighted material within the boat anchor cavity to unload the submerged anchor providing a much lighter anchor lift or pull back.

(18) FIG. 2 shows a one anchor line semi-hollow fluke variable weight boat anchor in an embodiment of the invention. An embodiment of a variable weight boat anchor has an anchor base 207 integrated with a storage volume for temporary storage of solid matter. The anchor's at least one anchor fluke 209, and the anchor base 207 rigidly coupled to at least one line coupling loop 205 for at least one boat line 201 secured to the anchor base 207, with the anchor base integrated with a storage volume 210 from a hollow space or cavity within a fluke 209. A boat anchor drop line 201 functions partly as a mechanism to release and unload materials within the fluke 209 integrated storage cavity 210 while submerged.

(19) A release mechanism includes a remotely operated trigger at the line 201 boat end. The trigger can come in the form of the drop anchor line 201 which when pulled in a certain way transfers the line lead 211 to the anchor opposite end 213 and will initiate a release of the stored matter from the storage volume 210 by overturning the anchor. In and embodiment of the invention the integrated fluke 209 may be partially closed with holding surfaces 208 such that the stored matter will not be released from typical anchor water bottom movement. Thus the trigger from an anchored boat sent to release the heavy material within the boat anchor would unload the submerged anchor providing a much lighter anchor lift or pull back.

(20) FIG. 3 illustrates anchor content release mechanism of a variable weight boat anchor in an embodiment of the invention. In and aspect of the invention a mechanical release mechanism is shown. A drop anchor line 319 with an upward pull to push a bead 311 or other agent against a spring loaded closure bar 313 integral with an anchor loop 315 rigidly coupled to the anchor body 317 and acts as a simple gate to release the line 319 from the loop 315. The closure bar 313 is integral to the loop 315 and is shown closed firmly holding the line 319 from leaving the loop. The line 319 end is tied coupled to an anchor bottom or content release mechanism from which line 319 freedom from the loop 315 from tension or pull from the boat will initiate the line 319 coupled to the overturning to empty the anchor storage cavity and dispose of the weighting material.

(21) In an alternate embodiment of the invention, an electro mechanical release mechanism is described. The water tight release mechanism will have an acoustic transducer 325 coupled to a power sourced 327 solenoid 323. A sonar signature from the boat will be sensed by the transducer 325 and will energize the solenoid 323 and cause the coupler 321 open a spring loaded closer bar 301 303, shown open, to release the anchor line 307. The line 307 end is tied coupled to an anchor bottom or content release lever from which line 307 freedom from the loop 305 with tension or pull from the boat will initiate the line 307 triggering the release mechanism to empty the anchor storage cavity and dispose of the weighting material.

(22) FIG. 4 depicts a hollow anchor housing with bottom opening release mechanism in a two-line embodiment of the invention. A boat 401 on the surface is shown having two lines 403 405, one line to the anchor body 407 409 and the other line to a release mechanism. Slack shown in the two lines 407 depicts the anchor at rest on the water bottom, and a taught pulled line anchor 409 depicts an engaged release mechanism spilling its heavy material out as the anchor is pulled up.

(23) In a very basic embodiment of the invention, there are two ropes or lines: one attached to the top of the anchor and one to metal loop at the bottom. The rope attached to the bottom of the anchor or release lever can be color coded at the boat 401 end so a person can know to pull on that end when leaving. The anchor empties 409 of the loaded material as it is pulled up. The anchor cavity portion of the anchor contains a kind of pocket along each anchor fluke or alternatively an anchor housing volume such that heavy material such as rock, gravel, aggregate, etc. can be contained. When the anchor is ready to be pulled up the color coded rope is pulled first so that the loose heavy material contained in the anchor cavity is discarded and a much lighter anchor is pulled up.

(24) FIG. 5 shows a anchor integrated housing cavity for storage of heavy material and release mechanism in an embodiment of the invention.

(25) A two-line variable weight anchor is shown with the main drop and pull anchor line 502 tried coupled to the anchor loop 503 which is rigidly coupled to a housing 505 and integrated cavity 507. The housing cavity 507 has a closed opening 511 which is opened by lever 509 connected to a release line 501. A pull from a boat above will release the weighty material from inside the housing cavity 507 and draw the anchor to the boat wishing to pull anchor. The release line maybe a much less tension test line as the release opens the cavity 507 and the action of pulling the anchor towards the boat will release the weighting material.

(26) A one-line variable anchor embodiment is shown attached to a single line 523 connected to an loop 519. The loop 519 is coupled to a housing with an internal cavity 520 for storage of weighty matter. Upon triggering with a pairing signature acoustic signal from a boat received by an electro-mechanical device 521 release mechanism coupled to a lever 517 opening 515 the housing cavity 520 and releasing housing storage cavity 520 weighting material 513. The electro-mechanical device 521 releasing mechanism will include a transducer to receive acoustic signal and logic to decode a paired signature signal from a boat to energize a solenoid or pulling gear with a power supply. The device 521 release mechanism will be water tight sealed and coupled to the anchor housing 520.

(27) FIG. 6 illustrates a one-line variable weight anchor having a body housing cavity with stored material release mechanism and integrally coupled flukes in an embodiment of the invention.

(28) A one-line variable weight anchor is shown with the main drop and pull anchor line 601 coupled to the anchor loop 603 which is rigidly coupled to an anchor body housing 605 having and integrated storage cavity 605. The body housing 607 having an internal storage cavity with a door 611 621 which is opened by lever 613 or alternate mechanical device connected to a release puller 615. A known signature acoustic signal from a boat above will trigger release of the weighty matter 609 from inside the housing cavity 605 and allow drawing the lightened matter-free anchor to the boat signaling to pull anchor. In an embodiment of the invention the release coupler 615 is a component of a electro-mechanical releasing device 617 having an acoustic transducer with logic to receive an authorized trigger from the boat for opening the anchor storage cavity 605 and power with mechanical coupling to open the storage cavity 611 door. The release mechanism and the action of pulling the anchor towards the boat will unload the weighting material and present with a much less weighty anchor for pulling up to the boat. The anchor body 605 is rigidly coupled with one or more flukes 607 to add resistance to movement along certain water body bottoms.

(29) In another embodiment, a one-line variable weight anchor with integrated flukes can use a loop release mechanism whereby by the one-line 619 is used both for the release trigger and for the upward anchor pull.

(30) Therefore, while the invention has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this invention, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed herein. Other aspects of the invention will be apparent from the following description and the appended claims.
