Patent ID: 7600956

Claim:
An anchoring device for insertion in a hole provided in a structure, the device comprising: a proximal section and a distal section disposed along a longitudinal anchor axis; the proximal section including a head portion defining an aperture for receiving a fastener and including at least one leg adapted to move between a retracted position and an expanded position, the leg, when in the expanded position, being adapted to radially exert pressure on a wall material delimiting the hole to secure the anchoring device within the hole; the distal section including a wedge and at least one expandable wing adapted to move between a retracted position and an expanded position, the distal section being adapted to longitudinally move toward the proximal section thereby causing the at least one expandable wing to engage the structure in the expanded position thereof and also causing the wedge to displace the leg from the retracted position to the expanded position thereof for securing the anchoring device within the hole, wherein the distal section includes a flexible portion disposed between the wedge and the at least one expandable wing.
