Skoog, 322 Kent Road, Hoyt Lakes, Minn. 55750 Filed Aug. 29, 1968, Ser. No. 756,150 Int. Cl. B63b 21/30 US. Cl. 114--206 4 Claims ABSTRACT OF THE DISCLOSURE A ring-like body having a flexible elongated retainer connected at each end to said body on a diameter thereof together with a connector slidably mounted on the re tainer for connection with an anchor line, the inner surface of said ring converging inwardly from one edge to the other.

SUMMARY OF THE INVENTION The invention relates to an improvement in anchors for boats and more particularly to an anchor which when lowered onto the bottom of a body immediately starts to sink into the bottom material. The anchor includes a ring-like body having a flexible retainer member connected at each end to the ring on a diameter thereof, the length of the retainer being greater than the diameter of the ring. A connector is slidably mounted on the retainer and with an anchor line connected to the connector and a pull exerted on the line the portion of the ring body opposite to the direction of pull digs into the bottom upon which the anchor is placed. Further, as the ring body is placed on the bottom, sand and/or mud is positioned within the ring. As a pull is exerted on the anchor line the ring body digs in progressively as a pull is exerted on the anchor line. On a rocky bottom the ring can easily engage a projection of a rock and weighing of the anchor is easily accomplished by drawing the same upwardly from the bottom by means of a vertical pull somewhat in the position shown in FIG. 3.

These and other more detailed and specific objects will be disclosed in the course of the following specification, reference being had to the accompanying drawings, in which- FIG. 1 is a side elevational view of an anchor embodying the invention positioned on the bottom of a body of water.

FIG. 2 is a top plan view of the anchor with the retainer chain held in an upright position.

FIG. 3 is a sectional view on the line 33 of FIG. 2.

Referring to the drawings in detail, the anchor A includes the circular ring body 10. The body includes the outer surface 12 which is substantially parallel to the axis XX of the ring. The inner surface 14 of the ring body 10 is angularly disposed to the axis XX converging toward the axis from top to bottom of the ring body. As a result the ring in cross section is larger on the lower edge than on the upper edge.

Secured to the ring body 10 adjacent the top edge thereof is a first connecting link 16 and secured to the ring body adjacent the top edge is a second connecting link 18, both connecting links being oppositely disposed and located on a single diameter of the ring body.

The numeral 20 designates a flexible retainer member in the form of a chain which is connected at one end to the link 18 and at the other end to the link 16. In the drawn up'position of FIG. 3, the chain forms an angle at its apex of approximately 125 degrees to 130 degrees. Briefly, the retainer 20 is longer than the extent of the diameter of the ring.

Further provided is the connector 22 which has a closed loop formation and through which the chain 20 freely extends so that the loop can be freely moved to various points along the chain. The numeral 24 designates a line which may be connected to the connector by any wellknown conventional means.

In use the anchor A is lowered into the water W by means of the line and the line automatically centers upon the chain 20 due to the free movement of the chain 20 through the connector 22. As the anchor is lowered, the same contacts and rests substantially flat upon the bottom B in the position illustrated in FIG. 3. In such a position on a mud or sandy bottom, mud or sand is positioned within the confines of the ring body 10. From such a position the line 24, when attached to a boat, will pull and move the connector 22 upon the retainer chain 20 to substantially the position illustrated in FIG. 1. As such pulling occurs a segment of the ring body 10 opposed to the line of pull, such as at Y, is caused to dig into the bottom due to the angular disposition of the inner surface 14 of the ring body. With such a digging in the anchor becomes firmly entrenched in the bottom.

As the ring is pulled by the line 24 sand and mud piles up within the ring, and when such pulling movement is stopped, mud and sand within the ring body settles within the ring body thereby aiding the positioning of the ring body well within the mud and/or sand. With continued pulling the anchor ring body tend to go deeper into the sandy or mud bottom.

Due to the circular formation of the angularly disposed surface 14, the digging in is progressive starting at a point on a diameter of link 18. With reference to a rocky bottom the ring very eifectively snares and catches onto rocks. The anchor A is easily released from either a soft or rock bottom by pulling the anchor upwardly from a position directly over the anchor, for in such a position it will be seen that the ring body will easily lift free of rocks, debris, mud or the like for there are no protrusions to engage under rocks, etc. Further, the line 24 may pull from the connector 22 at either side of the ring, for the connector is slidable on the retainer.

When the anchor A is dropped onto the bottom B and a pulling force exerted, the anchor begins to dig in in the attitude shown in FIG. 1 and as heretofore described. With a pulling force to the right as viewing FIG. 1 the left or inner degrees of surface of the ring body provides resistance and tends to dig in due to the angular disposition of the surface 14, while the outer or right 180 degrees of surface of the ring also provides resistance and to a lesser degree digs in.

It is understood that suitable modifications may be made in the structure as disclosed.

Having now therefore fully illustrated and described my invention, what I claim to be new and desire to protect by Letters Patent is:

1. A boat anchor comprising:

(a) a body having a ring formation,

(b) a flaccid elongated retainer member connected at each end to said ring body on a diameter thereof,

(c) a connector carried by said flaccid retainer for connection with an anchor line.

2. The device of claim 1 in which the connector is slidably mounted on said retainer whereby a pulling force exerted on the line causes said connector to slide upon said retainer to a point removed from the center of the retainer thereby causing a portion of the ring body to dig into the bottom of a body of water on which the anchor is placed.

3. The device of claim 2 in which the length of the retainer is greater than the diameter of the ring body.

4. A boat anchor comprising:

(a) a body having a ring formation,

(b) a flaccid elongated retainer member connected at each end to said ring body on a diameter thereof,

(c) a connector carried by said flaccid retainer for (f) the inner circular surface of said ring body conconnection with an anchor line, verging inwardly from the top edge to the bottom (d) said connector being slidably mounted on said reedge to increase the digging in of the ring.
