Abstract: A wall anchor having a first inclined plane secured to a second inclined plane by a connector. The connector is resilient to allow the inclined planes to move relative to one another. The inclined planes are oriented opposite one another, in a manner which increases their combined height as the inclined planes slide in a first direction relative to one another, and which decreases their combined height as the inclined planes slide in a second direction relative to one another. A retainer is secured to the first inclined plane and is used to insert the inclined planes into a hole in a wall. After the inclined planes have been inserted, the retainer is withdrawn slightly, which causes the inclined planes to slide relative to one another and increase their combined height to wedge the inclined planes against an interior surface of the hole. In this manner, a retainer may be securely and manually anchored to a wall.
