Abstract
An anchor assembly including a threaded anchor and a threaded drive pin positionable in the threaded anchor, a method of using or installing the anchor assembly to attach a fixture to a substrate, and a method of removing or un-installing the anchor assembly from the fixture and the substrate to detach the fixture from the substrate.
Claims9
An anchor assembly comprising:
- a threaded drive pin including:
- a shank,
- a head integrally connected to the shank, the head defining a mechanical engaging structure to enable rotation of the threaded drive pin, and
- a helical thread formation integrally connected to and extending outwardly from the shank;
- and
- a threaded anchor including:
- an elongated tubular body including an inner surface defining a longitudinally extending inner channel, the body including at least two independently movable gripping arms,
- a head integrally connected to and extending from a first end of the body and including an inner surface that defines a longitudinally extending inner channel that is aligned with the longitudinally extending inner channel of the body, the head including a mechanical engaging structure to enable rotation of the threaded anchor, the head also defining a drive pin head receiving recess configured to receive the head of the threaded drive pin, and
- an external helical thread formation integrally connected to and extending outwardly from part of the body.

An anchor assembly threaded anchor comprising:
- an elongated tubular body including an inner surface defining a longitudinally extending inner channel configured to receive a shank of a threaded drive pin, the body including at least two independently movable gripping arms;
- a head integrally connected to and extending from a first end of the body and including an inner surface that defines a longitudinally extending inner channel that is aligned with the longitudinally extending inner channel of the body, the head including a mechanical engaging structure to enable rotation of the threaded anchor, the head also defining a drive pin head receiving recess configured to receive a head of the threaded drive pin;
- and
- an external helical thread formation integrally connected to and extending outwardly from part of the body.

A method of installing and removing an anchor assembly, said anchor assembly including a threaded drive pin including:
- (a) a shank, (b) a head integrally connected to the shank, the head defining a mechanical engaging structure to enable rotation of the threaded drive pin, and (c) a helical thread formation integrally connected to and extending outwardly from the shank;
- and a threaded anchor including:
- (i) an elongated tubular body including an inner surface defining a longitudinally extending inner channel, the body including at least two independently movable gripping arms, (ii) a head integrally connected to and extending from a first end of the body and including an inner surface that defines a longitudinally extending inner channel, the head including a mechanical engaging structure to enable rotation of the threaded anchor, the head also defining a drive pin head receiving recess configured to receive the head of the threaded drive pin, and (iii) an external helical thread formation integrally connected to and extending outwardly from part of the body, said method comprising:
- aligning a first object and a second object such that a first hole in the first object is aligned with a second hole in the second object;
- positioning the anchor assembly through the first hole partially into the second hole and such that the threaded drive pin is partially positioned in the threaded anchor;
- driving the threaded drive pin further into the threaded anchor causing the threaded drive pin to engage the interior ramps to cause the gripping arms to move outwardly to engage an interior surface that defines the second hole in the second object to secure the threaded anchor to the second object;
- causing a tool to engage the mechanical engaging structure of the head of the threaded drive pin and rotating the tool to rotate the threaded drive pin to remove the threaded drive pin from the threaded anchor;
- and
- causing the tool to engage the mechanical engaging structure of the head of the threaded anchor and rotating the tool to rotate the threaded anchor to remove the threaded anchor from the first object and the second object.
