DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to the drawings, an anchoring system in accordance with the invention is designated generally by reference numeral 10. The anchoring system 10 comprises a peg 12 which is operable to be driven into the ground 14 and an elongate connecting element in the form of a flexible steel cable 16 which is releasably attached to the peg 12.
The peg 12 comprises, broadly, a shank 18 defining a longitudinal axis A and having an upper end 20 and a lower end 22; and a helical screw formation 24 which is fixed to and which extends around a lower end region of the shank 18.
The anchoring system includes a handle 28 in the form of a bar 30 which is removably received in a sleeve 32 which is hingedly connected to the upper end of the shank 18 by means of a pivot pin 34. When located in the sleeve 32, the bar 30 extends transversely relative to the longitudinal axis A of the shank 26. The bar 30 includes a number of holes 34 in which split pins can be received to prevent the handle 22 from sliding out of the sleeve 32. By being hingedly connected to the shank, the sleeve 32 can be pivoted relative to the shank to permit the bar 30 to be disposed adjacent the shank in a compact space-saving configuration during transportation and stowage.
The shank 26 is in the form of a round tube defining a seat formation in the form of a longitudinally-extending groove 36 in a side thereof. The anchoring system includes three holding formations in the form of rubber clips 38.1 , 38.2 and 38.3 which are fixedly located within the groove 36 and which releasably grip the cable 16 when it is seated in the groove 36. In use, part of the cable 16 is received in the groove 36 when the peg 12 is screwed into the ground 14. This prevents the cable 16 from fouling as the peg 12 is screwed into the ground.
The cable 16 has a first end 40 and a second end 42. The first end is bent so as to form an eyelet 44 which provides an anchor point to which an object can be secured. The cable 16 has an end cap in the form of a collar 46 secured to its second end, which defines an aperture 48 therethrough. The lower end 22 of the shank 18 defines an aperture 50 therethrough and has a hinge pin 52 which is receivable in the aperture 50. As such, the second end 42 of the cable 16 is hingedly attached to the lower end of the shank by introducing the collar 46 into a lower end of the groove 36, aligning the apertures 48 and 50 and passing the hinge pin 52 therethrough. The cable 16 can be released from the shank 18 by removing the hinge pin 52.
The anchoring system includes a boring attachment 54 which is attached to the lower end of the shank for boring into the ground. The boring attachment includes a pair of curved boring blades 56.1 and 56.2 which bore into the ground, in use, to form a pilot hole when the peg is caused to rotate and a downward force is applied thereto.
In use, the anchoring system 10 provides an anchor point to which a tensile load such as the pulling force exerted by of a vehicle winch cable, can be applied. The anchoring system 10 is prepared for operation by attaching the collar 46 to the shank 18 and seating the cable 16 in the groove 38. The peg 12 is then screwed into the ground 14 by applying downward pressure and a rotational force to the shank 18 via the handle 28, after a pilot hole has been bored in the ground by the boring attachment 54, leaving part of the cable 16 and the eyelet 44 above ground and forcing the second end 42 of the cable 16 below ground. The cable 16 is releasably held in the groove 36 by the clips 38 thereby preventing the cable 16 from fouling as the peg 12 is screwed into the ground. With reference to Figure 3, a vehicle 60 is illustrated, by way of example, which has a winch cable 62 hooked into the eyelet 44. The groove 36 in the shank 18 faces the vehicle 60 so that the cable 16 is pulled out of the groove 36 as the cable 16 is tensioned. As the winch cable 62 exerts a pulling force "F" on the eyelet 44, the force is transferred by the cable 16 to the lower end of the peg 12. Because the lower end of the peg is buried in the ground, the force "F" required to pull the peg out of the ground will be greater than would be of the case if the cable 16 was fixed to the upper end of the peg 12. The force "F" is applied to the peg in a direction oblique to the longitudinal axis A, which has the effect of making the cable 16 cut into the ground 14 as the force exerted by the cable on the peg increases. The eyelet 44 thus provides an above-ground anchor point to which a tensile load can be applied.
It must be appreciated that the exact configuration of the anchoring system 10 may vary greatly while still incorporating the essential features of the invention as defined and described hereinabove. It will also be appreciated that the anchoring system in accordance with the invention, may be used in a wide range of applications such as for anchoring the stays of a tent to the ground.
