Patent ID: 8128329

Claim:
A wall anchor attachable to a wall, said wall defining a wall aperture, said wall anchor being substantially elongated and comprising: a proximal body element and a substantially longitudinally opposed distal body element, said proximal and distal body elements being substantially longitudinally movable relatively to each other, said proximal body element defining a substantially radially extending flange for abutting against said wall when said proximal body element is inserted in said wall aperture; a substantially elongated retention element provided between said proximal and distal body elements and pivotally coupled to each of said proximal and distal body elements so as to be reversibly movable between a retracted configuration and an expanded configuration, wherein, in said retracted configuration, said retention element extends substantially longitudinally between said proximal and distal body elements, and, in said expanded configuration, said retention element extends substantially transversally between said proximal and distal body elements; an actuator operatively coupled to said retention element for selectively moving said retention element between said expanded and retracted configurations; a proximal linking element extending between and pivotally coupled to both said proximal body element and said retention element; and a distal linking element extending between and pivotally coupled to both said distal body element and said retention element; wherein said actuator is operatively coupled to said proximal and distal body elements so as to be able to move substantially longitudinally proximal and distal body elements relatively to each other to cause movements of said retention element between said retracted and expanded configurations; and wherein said proximal and distal linking elements are substantially diametrically opposed with respect to each other.
