Claims20
A self-drilling expandable anchor comprising:
- an expandable member including:
- a base including a front surface, a back surface, and four side edges, and
- an expandable tube connected to and extending from the front surface of the base, the expandable tube including:
- a first section including inner threads, and
- a second section not including inner threads,
- the second section extending between the first section and the base,
- the second section being expandable relative to the first section and relative to the base,
- the base and the expandable tube defining an inner passageway;
- a member partially extending through the expandable member, the member including:
- a head, and
- a shaft including:
- a first section including a first end connected to the head,
- no outer threads on the first section,
- a second section including a second end opposite the first end, and
- outer threads on the second section, the outer threads engaging the inner threads of the first section of the expandable tube;
- a drill head including:
- a connector, and
- a drill tip connected to and extending from the connector, the connector including inner threads engaging the outer threads on the second section of the shaft;
- a friction reducing element journaled about the second section of the shaft and positioned between the base of the expandable member and the head of the member;
- and
- a hanger including:
