Abstract
An anchor for anchoring a structure to the ground includes an anchor shank (10) having a connection point (18) at which a connecting member is coupled to the anchor shank (10). An anchor body (12) is pivotally connected to the anchor shank (10) at a point (14) remote from the connection point (18).
Claims15
An anchor for anchoring a structure to the ground, the anchor operable to couple to the structure through a connecting member, the anchor comprising:
- an anchor shank having:
- a first end and a second end, the first end providing a driving surface for the anchor;
- a connection feature positioned proximate the first end, remote from the driving surface and offset from a central axis of the anchor shank, the connection feature for coupling the connecting member to the anchor shank;
- a pivot slot positioned proximate the second end and offset from the central axis of the anchor shank in the same direction as the connection feature, such that the pivot slot is substantially in-line with the connection feature;
- and
- an anchor body pivotally connected to the anchor shank at the pivot slot, the anchor body having:
- a first end and a second end, the anchor body connected to the pivot slot intermediate the first end and the second end of the anchor body;
- and
- the first end of the anchor body formed with an angled portion that extends away from the central axis of the anchor shank in the same direction as the offset of the connection feature, the angled portion for engaging with the ground when the anchor is set;
- the anchor having a pre-set state in which the anchor body is pivoted in the pivot slot to be parallel with the anchor shank with the first end of the anchor body extending towards the first end of the anchor shank and to be substantially in-line with the connection feature and the pivot slot;
- and
- the anchor having a set state in which the anchor body is pivoted in the pivot slot to no longer be parallel with the anchor shank.

- an anchor shank having:
- a first end and a second end, the first end providing a driving surface for the anchor;
- a connection feature for receiving the connecting member, the connection feature proximate the first end and remote from the driving surface of the anchor shank;
- and
- a pivot slot positioned proximate the second end and remotely disposed from the connection feature;
- and
- an angled shoulder positioned between the connection feature and the pivot slot, the angled shoulder extending away from a center axis of the anchor shank and extending towards the second end of the anchor shank to form an acute angle;
- and
- an anchor body pivotally connected to the anchor shank at the pivot slot, the anchor body having:
- a first end and a second end, the anchor body connected to the pivot slot intermediate the first end and the second end of the anchor body;
- and
- a cross-portion extending across the first end of the anchor body;
- the anchor having a pre-set state in which the anchor body is pivoted in the pivot slot to be parallel with the anchor shank with the first end of the anchor body extending towards the first end of the anchor shank and with the cross-portion of the anchor body positioned proximate the angled shoulder of the anchor shank;
- the anchor having a set state in which the anchor body is pivoted in the pivot slot to no longer be parallel with the anchor shank;
- and
- the angled shoulder of the anchor shank contacting the cross-portion of the anchor body when the anchor is set such that the angled shoulder directs the anchor body in the pivoting direction.
