Abstract

An anchor device including an expansion section expandable when an expansion screw is screwed into the anchor device, and a tubular shank into which the expansion screw can be screwed. The anchor device has a joining device with an elongated offset element as well as a joining element. The first end of the offset element is connected to the tubular shank in such a way that the offset element extends essentially perpendicular to the tubular shank and to the expansion section. The second end of the offset element is connected to the first end of the joining element in such a way that the joining element extends essentially perpendicular to the offset element and essentially parallel to the tubular shank and to the expansion section.

First claim

What is claimed is:

1. An anchor device comprising:
an expansion section extending over part of a total length of the anchor device and expandable when an expansion screw is screwed into the anchor device;
a tubular shank, the expansion screw insertable into the tubular shank; and
a joining device having an elongated offset element as well as a joiner, the elongated offset element having a first end as well as a second end, and the joiner having a first end as well as a second end, the first end of the offset element being connected to the tubular shank in such a way that the offset element extends perpendicular to the tubular shank and to the expansion section, and the second end of the offset element is connected to the first end of the joiner in such a way that the joiner extends perpendicular to the offset element and parallel to the tubular shank and to the expansion section.

2. The anchor device as recited in claim 1 wherein the joining device has a tubular insertion shank situated at the first end of the offset element, the tubular shank accommodatable in the tubular insertion shank in order to be joined to the offset element.

3. The anchor device as recited in claim 2 wherein the expansion section is made of plastic.

4. The anchor device as recited in claim 2 wherein the expansion section has two longitudinal slits.

5. The anchor device as recited in claim 2 wherein the expansion section has two expansion legs.

6. The anchor device as recited in claim 2 further comprising the expansion screw attached to the expansion section.

7. The anchor device as recited in claim 2 wherein the offset element has a first side and a second side, the expansion section being situated on the first side and the joining device solely on the second side.

8. The anchor device as recited in claim 2 wherein the expansion element is placeable in a hole in an outer surface of a material, the offset element having a first side and a second side, the expansion element being situated on the first side, the first side for being outside the outer surface and facing the outer surface.

9. The anchor device as recited in claim 1 wherein the joiner is a setscrew.
