Abstract
A wall anchor attachable to a wall, the wall defining a wall aperture. The wall anchor includes a body; a retention element operatively coupled to the body so as to be reversibly movable between a retracted configuration and an expanded configuration, wherein, when the retention element is in the retracted configuration, the wall anchor is insertable into and removable from the wall aperture, and, when the retention element is in the expanded configuration and the body is operationally extending through the wall aperture, the retention element cooperates with the body to attach the wall anchor to the wall; and an actuator operatively coupled to the retention element for selectively moving the retention element between the expanded and retracted configurations. Inserting the wall anchor through the wall aperture with the retention element in the retracted configuration and subsequently using the actuator to move the retention element to the expanded configuration attaches the wall anchor to the wall. Using the actuator to move the retention element from the expanded configuration to the retracted configuration with the wall anchor attached to the wall allows for the removal of the w…
