Patent ID: 7547171

Claim:
A convertible anchor for friable walls, comprising a fixture for holding an article to a support and anchoring means being connected to and extending from said fixture, wherein said anchoring means is rotatable about an axis thereof to engagingly extend into a friable wall for securing said fixture to the wall, wherein said fixture is selectively separable from said anchoring means for allowing said fixture to be used alone with an appropriate fastener that mounts said fixture to a rigid structure, wherein a frangible connection is provided between said fixture and said anchoring means, said frangible connection being adapted to allow the assembly of said fixture and said anchoring means to be rotatably installed to the friable wall while being adapted to be selectively broken for separating said fixture from said anchoring means, wherein said anchoring means comprises a toggle support extending from said fixture and being frangibly connected thereto, a toggle bolt pivotally mounted to said toggle support between a first and second position, and a fastener, wherein in said first position said toggle bolt is substantially parallel to said toggle support to allow said anchoring means to be engaged in the friable wall, whereas in said second position said toggle bolt is substantially transversal to said toggle support, said fastener being adapted when introduced along said toggle support to cause said toggle bolt to displace from said first to said second position and to then threadably engage said toggle bolt for drawing said toggle bolt towards said fixture and against a non visible side of the friable wall thereby securing said anchor to the friable wall, and wherein said frangible connection comprises a pair of parallel elements extending parallelly to said toggle support and connecting a proximal end of said toggle support to said fixture.
