1. An anchor element for an anchor and support assembly, comprising an upper clamp element, wherein the clamp element is a sheet element having a uniform thickness D, and having a planar central portion with a nominal periphery P, and extending along and about a principal plane along an upper clamp axis transverse to a central axis, wherein the sheet element has:
A. a coupling region disposed about the central axis and within the central portion, and B. at least three elongated tab elements, each tab element extending along an associated tab axis from the nominal periphery P, from a proximal portion at a proximal end thereof to a distal tab end, wherein a principal plane of the proximal portion extends along and is parallel to the principal plane, i. wherein each of the tab axis is co-planar and transverse to and extend radially outward from the central axis, ii. wherein each of the tab elements includes at its distal tab end, a capture bend region, whereby the tab axis of a distal portion of the tab element extends from an intermediate point, away from the principal plane in a first direction, and thereafter extends toward and across the principal plane in a second direction to the distal tab end, iii. wherein each of the tab elements includes a primary bend region between its proximal portion and the intermediate point, whereby a distal portion of the tab element extending from the intermediate point to the distal tab end extends transverse to the tab axis in a direction perpendicular to the principal plane, between a first lateral edge on one side of the principal plane and a second lateral edge on the other side of the principal plane, and wherein each distal portion includes a slot having a predetermined width W extending from the first lateral edge into the distal portion along an associated slot axis parallel to and a distance S from the central axis. |
