Abstract
A protrusion anchor assembly is provided that utilizes a plurality of extendable pins to secure the anchor body within a bore in any hard material, such as concrete. The anchor body is rotated within the bore while the pins are simultaneously and gradually extended, carving out a groove or grooves within which the pins can sit. After installation, the device is secured within the bore by tightening a jamb nut against the surface of the concrete wall and in some embodiments placing a security plug within the anchor body to ensure that the pins are held in place. The pins prevent the anchor from being withdrawn because they act as protuberances that catch against the edges of the groove and cannot be drawn past that point.
Claims13
1) A protrusion anchor fastener, comprising:
- an anchor body having an upper threaded portion and a lower portion;
- said lower portion having an end cap hole at its terminal end and a plurality of anchor holes;
- said anchor body having an internal bore extending therethrough;
- a protrusion actuator having a driver end and a tapered end;
- a plurality of pins having an inner rounded end and an outer end, said pins adapted to be pushed through said anchor holes by said protrusion actuator and engage with surrounding material as said protrusion actuator is depressed;
- a jamb nut adapted to engage with said external thread and secure said anchor body against a concrete surface.
7) A protrusion anchor installation tool, comprising:
- a driver rod with a pad;
- a body portion having an upper tool portion and a lower tool threaded portion;
- said body portion having a channel through which said driver rod is inserted;
- said lower tool threaded portion adapted to engage with said upper threaded portion and be secured thereto;
- said driver rod adapted to push said protrusion actuator through said internal bore;
- said upper tool portion having an engagement means.
8) A protrusion anchor assembly, comprising:
- an anchor body having an upper threaded portion and a lower portion;

- said anchor body having an internal bore extending therethrough;
- a protrusion actuator having a driver end and a tapered end;
- a plurality of pins having an inner rounded end and an outer end, said pins adapted to be pushed through said anchor holes by said protrusion actuator and engage with surrounding material as said protrusion actuator is depressed;
- a jamb nut adapted to engage with said external thread and secure said anchor body against a concrete surface;
- an anchor installation tool having a driver rod with a pad and a body portion having an upper tool portion and a lower tool threaded portion;
- said body portion having a channel through which said driver rod is inserted;
- said lower tool threaded portion adapted to engage with said upper threaded portion and be secured thereto;
