DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field Of The Invention
This invention relates to a ground anchor.
Throughout the ensuing description and claims reference will be made to an especially preferred embodiment of, the arrangement in accordance with the present invention, namely as and in a ground anchor. It should be realised, however, that the invention is not to be considered to be limited to such preferred embodiment and usage. Indeed, the arrangement in accordance with the present invention lends itself to usage in a variety of different contexts, in effect in any context or environment where an anchoring means is required.
2. Description Of The Prior Art
Off-road vehicles, such as 4-wheel drive vehicles, tractors and agricultural machinery which venture off made roads, will occasionally become bogged or stuck in mud or in soft sand.
While many such vehicles have powerful winches which might be used to winch the vehicle to safe ground, it is necessary to attach a cable of such a winch to a relatively immovable object so that the winch has something to act against.
However in so terrains it may be difficult, if not almost impossible, to find a relatively immovable object at sufficiently close proximity to be useful.
Accordingly, the present invention seeks to provide a device which might be used for debogging a vehicle.
SUMMARY OF THE INVENTION
In accordance with the present invention, therefore, there is provided an anchor comprising: an elongate, substantially cylindrical member; two substantially triangular shaped plate members adapted to be pivotally mounted on or to said elongate member whereby to be selectively and pivotally movable relative to said elongate member between a first storage position, wherein said plate members abut or overlie one another, and a second in-use position, in which said plate members extend away from one another; a shank attached to said elongate member and adapted to extend substantially parallel thereto; and a further member attached to said elongate member, and operatively connected to said shank, said further member acting as a carrying means for said anchor and as a handle or control means to assist in ground-engagement thereof.
There may be retaining means for releasably retaining the plates in said second position.
The triangular plates may have holes in them. Such holes are useful in allowing water and/or sand or mud flow from one side of the anchor to another and may also be useful to create a handhold for carrying the anchor when the triangular plates overlie one another
A shank for the anchor may be provided.
The shank is preferably inclined at an angle of from 10.degree.-30.degree. to said axis, more preferably from 10.degree.-20.degree. and most preferably about 15.degree..
The shank may be releasably attachable to the anchor.
Bolts may be provided for releasably bolting the shank to the anchor.
The shank may be non-pivotable with respect to the anchor.
The trailing end of the anchor is preferably provided with plates which can be weighted or struck or stood upon to drive the anchor into the ground.
The trailing end of the anchor may be provided with handles or tie points to assist in retrieval of the anchor.
The pivotal mounting means may be a substantially circular bar or tube on which sleeves are mounted and at least one of the plates is mounted to the sleeves The bar or tube preferably has a pointed ground-engaging end. The bar or tube preferably carries a retrieval ring.
A handle or the like means may be provided for guiding the anchor in entering the ground. The guiding is preferably done at an end away from the ground-entering end. That handle may fold and, in folded condition, function as carrying means or handle. The handle preferably can be releasably attached to the shank in the folded condition, such attachment being preferably by means of a linkage.
The handle preferably carries latch means for releasably holding the plates in a first, not-in-use or storage position.
Preferably there is a foot which will raise the trailing end of the anchor with r
