The housing assembly is rotably mounted and partially houses the common shaft and a chain member connects the shank assembly to the housing.
Description




II. BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a boat anchor, and more particularly, to the type that has a self release mechanism.




2. Description of the Related Art




Boating is a popular sport enjoyed by many. While boating, it is often necessary to set anchor to remain stationary. Various anchors have been designed in the past of many shapes and sizes. However, typically when an anchor is set, it becomes entangled with vegetation or structures on the floor of the body of water. Often, boaters spend much time and energy trying to free an anchor when severely entangled. In extreme cases, one may have to dive into the water to physically disentangle the anchor from the floor or structure it is entangled with.




There is a need for an anchor with a self release mechanism. One that serves the purpose to effectively keep a vessel stationary when anchored, but with a built-in release mechanism to facilitate the deanchoring process.




There are no similar boat anchors to the best of applicant's knowledge, that have a built-in self release mechanism and release when properly positioned.




III. SUMMARY OF THE INVENTION




It is one of the main objects of the present invention to provide a boat anchor that will free itself upon the application of a pulling force opposite from the angle where anchored.




It is another object of this invention to provide an anchor that is easy to raise.




It is yet another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.




Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.











IV. BRIEF DESCRIPTION OF THE DRAWINGS




With the above and other related objects in view, the invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:





FIG. 1

represents a perspective view of the present invention.





FIG. 2

shows a top view of the present invention.





FIG. 3



a


illustrates an elevational side view of the present invention in the anchored position with a water craft in phantom.





FIG. 3



b


illustrates an elevational side view of the present invention deanchoring with a water craft in phantom.





FIG. 4

shows an isometric view of the housing assembly.











V. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawings, where the present invention is generally referred to with numeral


10


, it can be observed that it basically includes shank assembly


30


, arm assembly


40


, and housing assembly


50


.




As seen in

FIG. 1

, boat chain


20


has links


22


interconnected, forming a chain and is fastenly secured to shank assembly


30


by ring


24


. Shank


36


, as an elongated member, is swively secured to arm assembly


40


by pin


44


and anchor chain


32


by ring


34


.




Arm assembly


40


has arms


42


which contain shaft


62


of common shaft assembly


60


and meet at either side of shank


36


. In the preferred embodiment, housing assembly


50


has generally triangular flukes


52


and


52


′ connected to housing


68


. Perpendicularly extending from housing


68


are vertexes


61


and


61


′. When placed on a surface, vertex


61


creates a fulcrum effect which causes either end of fluke


52


or


52


′ to contact the surface. Hingedly secured to vertex


61


′ is connector


38


. Connector


38


has ring


34


at its end, which connects to anchor chain


32


. Anchor chain


32


is of a length to limit the rotation of housing assembly


50


.




As seen in

FIG. 2

, shaft


62


, fixedly secured to arms


42


, rotates within housing


68


. Shank assembly


30


is swively secured inbetween arms


42


by pin


44


.




As seen in

FIG. 3



a


, instant invention


10


has been placed upon floor F of water W and has anchored. To successfully anchor, fluke


52


or


52


′ will drag upon floor F momentarily until wedging into floor F or a fixture upon it. In the preferred embodiment, flukes


52


and


52


′ have identical shapes, and are shaped to facilitate a wedging action. After instant invention


10


secures itself to floor F, water craft WC will generally drift with the current until boat chain


20


is extended. When in the anchored position, fluke


52


, in this example, is secured into floor F. Arms


42


raise until tabs


64


of shaft


62


make contact against edges


66


. Pulling pressure from boat chain


20


keeps tabs


64


biased against edges


66


, thus keeping fluke


52


under pressure and in floor F.




As seen in

FIG. 3



b


, water craft WC is in position to deanchor. As water craft WC is positioned to deanchor, boat chain


20


slacks. In this position, as arms


42


lower, tab


64


pressure is removed from edge


66


, thus unlocking. This allows arm assembly


40


, and shaft


62


to rotate within housing


68


. In the unlocked position, fluke


52


easily deanchors as boat chain


20


is pulled.




As best seen in

FIG. 4

, shaft assembly


60


has shaft


62


with tabs


64


partially covered within generally cylindrical housing


68


. In the locked configuration, tab


64


is biased against either edge


66


. To unlock and deanchor, arm assembly


40


, seen in

FIG. 1

, is lowered. Upon lowering arm assembly


40


, tab


64


pressure is removed from edge


66


. This causes shaft


62


to drop within housing


68


, allowing tabs


64


to maneuver within and deanchoring is facilitated.




The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
