Very high strength swivel anchor

摘要

A method and an anchor for supporting items on a substrate such as drywall. The anchor comprises a structure configured to carry the anchoring element in a minimal cross section configuration through an insertion hole and to effect a first expansion. The anchor further comprises an adjustable cap member configured to be moved to fixedly position the anchoring element to the non-accessible side of the substrate. The anchoring element comprises a base channel member, a top channel member, and a connector-pivoting element configured to pivotally connect the top channel member to the base channel member. The top channel member is configured to be nested with the base channel member in the minimal cross section configuration and to be pivotally rotatable via the connector pivoting element in the plane parallel to the non-accessible side of the wall, with the pivotal rotation of the top channel member providing the second expansion.

1. An anchor, in combination with a substrate providing support therefor, the substrate comprising an accessible side and a non-accessible side, and the anchor being configured for supporting objects on the accessible side of the substrate, the anchor comprising:
an anchoring element configured for insertion into a minimal sized insertion hole formed in the substrate, for placement of the anchoring element for anchoring support on the non-accessible side of the substrate, the anchoring element comprising: first and second expansion anchoring elements which are configured for assuming a minimal cross section configuration for insertion through the minimal sized insertion hole and being positioned and expanded on the non-accessible side of the substrate, and a connector-pivoting element configured to closely pivotally connect the first expansion anchoring element to the second expansion anchoring element, to enable the second expansion anchoring elements to be pivotally rotatable via the connector pivoting element only in a plane parallel to the first expansion anchoring element, and wherein the first and second expansion anchoring elements are held only in respective planes substantially parallel with each other, with the first expansion anchoring element being configured to be moved after said insertion to a first expansion position for load bearing in a fixed position against the non-accessible side of the substrate, wherein the second expansion anchoring element is configured to thereafter be moved to a second load bearing expansion position of the anchoring element after the first expansion is fixedly held in the position of bearing support against the non-accessible side of the substrate with the pivotal rotation of the second expansion anchoring element providing the second expansion, and wherein the connector-pivoting element permits the second expansion anchoring element to be rotationally pivoted only in a plane substantially parallel to the first expansion anchoring element, and wherein the first and second expansion anchoring elements of the anchoring element are configured to extend in at least two different expanded directions and in at least three different directions relative to the insertion hole and with at least part of the anchoring element proximally crossing the insertion hole.
