Anchoring Device

Abstract

An anchoring device comprising a shaft, at least part of whose length comprises a tapered portion, with at least one helical flange which runs substantially along the length of said tapered section and an engagement means to allow the device to engage with a lever wherein in use rotation of the lever about the axis of the shaft results in rotation of the device such that the tapered portion and the helical flange co-operate to drive the device into the ground.

1 . An anchoring device comprising a shaft, at least part of whose length comprises a first tapered portion, with at least one helical flange which runs substantially along the length of said first tapered portion and an engagement means to allow the device to engage with a lever wherein in use rotation of the lever about the axis of the shaft results in rotation of the device such that the first tapered portion and the helical flange co-operate to drive the device into the ground. 
   
   
       2 . An anchoring device as claimed in  claim 1  wherein the first tapered portion occupies a majority of the length of the shaft. 
   
   
       3 . An anchoring device according to  claim 1  wherein the diameter of the helical flange is uniform along the majority of the length of the first tapered portion of the shaft. 
   
   
       4 . An anchoring device according to  claim 1  which further comprises a plate positioned perpendicular to the length of the shaft at or adjacent the end of the device distal from the said first tapered portion. 
   
   
       5 . An anchoring device according to  claim 1  which further comprises a masonry bit attached to the end of the shaft adjacent of said first tapered portion. 
   
   
       6 . An anchoring device according to  claim 1  wherein the shaft further comprises a second tapered portion proximal to the end of the shaft distal to the first tapered portion wherein the cross-section of the shaft increases in a direction away from the first tapered portion of the shaft. 
   
   
       7 . An anchoring device according to  claim 1  wherein the shaft of the device is hollow and further comprises a threaded section in the hollow. 
   
   
       8 . An anchoring device according to  claim 1  wherein small protrusions are present on the first tapered portion of the shaft. 
   
   
       9 . An anchoring device as claimed in  claim 8  wherein the protrusions are pyramidal. 
   
   
       10 . An anchoring device according to  claim 1  wherein the device is colour coded. 
   
   
       12 . An anchoring device according to  claim 1  wherein the device incorporates drainage holes to prevent the retention of water in the hollow shaft and/or in the engagement means of the device.
