Abstract
An anchor comprising a shank having a forward and a rear end with a plurality of flukes secured to the rear end of the shank. The plurality of flukes are secured to the shank by a fluke mounting element. The plurality of flukes are radially oriented and angularly spaced apart and positioned on the fluke mounting element. A plurality of arm elements are radially aligned and oriented with respect to the fluke mounting element. Each of the plurality of flukes may be provided with an inwardly sloped bill segment at a distal end thereof.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to anchors for marine use and other aquatic uses, and in particular to anchors having multiple flukes and multiple arm elements.
2. Description of Related Art
Many different anchor types have been proposed and implemented for holding a boat in a particular place by means of a fluke which digs into the bottom of an ocean, lake, or river. Numerous shapes of anchors have been proposed including grapnel, “A” frame, yachtsman's, mushroom, and Danforth (limited pivoting fluke).
One serious limitation of prior anchors, and in particular the Danforth type of anchor is that they have a tendency to roll in the direction of a sideways pull, such as which may occur with a shift of wind, tide, or current. Such a roll is often the precursor of one or both of the flukes breaking out of the sea floor. Often the anchor in such situations fails to reset itself, and skates along on the edge of one fluke and the shackle end of the shank.
Although there have been prior attempts to solve the problem of anchor rolling and breakout by providing various modifications and accessories to conventional anchors, all such attempts have been cumbersome, un eliable, and ill-suited for serious use. Such limitations. have undoubtedly been a reason such anchor modifications have not received widespread acceptance.
It is of critical importance for an anchor to have the ability to catch and grab on uneven ground. The present invention provides a very simple yet extremely efficient and reliable solution to such limitations in prior anchors. Accordingly, it is the primary object of this invention to provide an anchor with a plurality of radially oriented and angularly spaced flukes which are combined with a plurality of radially aligned and oriented arm elements to provide quick and considerable grip and holding potential. Because of its unique configuration the anchor of the present invention also has a minimum level of dragging and fouling when pivoting and/or swinging with the change of tides and winds.
Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentality's and combinations particularly pointed out in the appended claims.
SUMMARY OF THE INVENTION
To achieve the foregoing objects, and in accordance with the purposes of the invention as embodied and broadly described herein an anchor comprising a shank having a forward and a rear end has a plurality of flukes secured to the rear end of the shank. The plurality of flukes are secured to the shank by a fluke mounting element. The plurality of flukes are radially oriented and angularly spaced apart and positioned on the fluke mounting element. A plurality of arm elements are radially aligned and oriented with respect to the fluke mounting element. Each of the plurality of flukes may be provided with an inwardly sloped bill segment at a distal end of the fluke.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to the present preferred embodiments of the invention as illustrated in the accompanying drawings.
In accordance with the present invention, there is provided an anchor comprising a shank having a forward and a rear end with a plurality of flukes secured to the rear end of the shank. The plurality of flukes are secured to the shank by a fluke mounting element. The plurality of flukes are radially oriented and angularly spaced apart and positioned on the fluke mounting element. A plurality of arm elements are radially aligned and oriented with respect to the fluke mounting element. Each of the plurality of flukes may be provided with an inwardly sloped bill segment at a distal end thereof. The flukes may be provided in a fixed or adjustable configuration.
In
FIG. 1
, a secure mooring connection anchor
10
is shown according to a preferred embodiment of the invention. Anchor
10
includes a shank
12
with a forward end
14
and a rear end
16
. Shank
12
may be variously configured, for example, cylindrical or rectangular, or other configurations well known in the art. A plurality of flukes
18
are secured to rear end
16
of shank
12
. Preferably the plurality of flukes
18
are secured to shank
12
by a fluke mounting element
20
, sometimes referred to in the art as an anchor crown, which may be variously configured and provided, for example, as a expanded late-like member as shown, or alternatively, be a fastening element for securing flukes
18
to shank
12
. Examples of fastening elements include a weld, a molded one piece unit, bolts, screws or the like. However, a fluke mounting element
20
, configured as seen in
FIG. 1
, or similarly, is preferred.
The plurality of flukes
18
, as seen in
FIGS. 1
,
2
and
3
, are preferably radially oriented with respect to shank
12
, and angularly spaced apart and positioned on fluke mounting element
20
, or alternatively to shank
12
. Flukes
18
are preferably composed of a durable resilient material such a metal. In a preferred embodiment, flukes
18
are configured with a inwardly sloped bill segment
24
at a distal end
26
of flukes
18
. Of course, various bill and fluke configurations may be provided, and the slope, angle, and size of bill
24
may alter depending on the embodiment.
As seen in
FIGS. 1
,
2
, and
3
a plurality of arm elements
22
are radially aligned and oriented in respect to shank
12
, and preferably one arm element is aligned with each of the plurality of flukes
18
. In different embodiments, however, it is possible to have some flukes without a corresponding arm element, or to have some or all of the arm elements not in corresponding alignment with the flukes.
With reference now to
FIG. 4
, a preferred configuration of an arm element
22
is shown. In this configuration a pointed tip and substantially triangular or pointed end is provided. In
FIG. 5
, another fluke and arm configuration and arrangement is shown, with arm
22
upwardly curved from fluke
18
. Many configurations of flukes
18
and arms elements
22
are possible. Of critical importance is the radial orientation and positioning of the plurality of flukes
18
and the plurality of arm element
22
about shank
12
, which provides significant gripping and holding power by the use of multiple flukes and arm elements in a radial configuration.
In operation and use, secure mooring connection anchor
10
is extremely versatile, reliable, easy to use, easy to transport and store, and highly efficient in gripping and holding a boat in position. In use, anchor
10
is used like any conventional anchor. However, because of the configuration of multiple flukes
18
and arm elements
22
very quick gripping and holding power is provided while also having a minimal level of dragging and fouling when pivoting and/or swinging with changes in wind and tide. The plurality of multiple flukes
18
and arm elements
22
allows for both deep rooting qualities and for providing security while riding at anchor. Anchor
10
will remain set securely or resets quickly after swinging at anchor.
Additional advantages and modifications will readily occur to those skilled in the art. The invention in its broader aspects is, therefore, not limited to the specific details, representative apparatus and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the applicant's general inventive concept.
