An anchoring device for insertion in a hole provided in a structure such as a wall (hollow or solid) comprises proximal and distal sections. The proximal section includes a head defining an aperture for receiving a fastener, and the distal section includes a pair of expandable wings displaceable between collapsed and expanded positions. Each wing is biased towards its expanded position such that the wings can engage the structural material delimiting the hole or a distal surface of the structure. The distal section comprises, proximally of the wings, a variable-length flexible portion for allowing the wings to engage the distal surface of the structure for various structure thicknesses. The distal section comprises, distally of the wings, a tip section adapted to spread outwardly when engaged by the fastener. The proximal section comprises a pair of legs each having a toothed rack for engaging the structural material.
An anchoring device for insertion in a hole provided in a structure, comprising proximal and distal sections, said proximal section comprising a head defining an aperture for receiving a fastener, said distal section comprising at least one expandable wing displaceable between inwardly collapsed and outwardly expanded positions, said wing being biased towards said expanded position such that said wing is adapted to at least one of engaging structural material delimiting the hole and engaging a distal surface of the structure.
An anchoring device as defined in claim 17, wherein there are provided two said legs separated by a pair of slots.
An anchoring device for insertion in a hole provided in a structure, comprising proximal and distal sections, said proximal section comprising a head defining an aperture for receiving a fastener, said proximal section comprising at least one leg, said distal section comprising a spreading member, said distal and proximal sections being displaceable towards one another such that said spreading member causes said leg to displace outwardly into engagement with the structural material delimiting the hole.
