Patent attributes
The present invention is a wall anchor having a novel finger configuration. This wall anchor has a head and barrel portion with a bore extending therethrough and laterally expandable fingers in general alignment with the bore. Instead of a straight channel, a channel having curved portions separates the fingers. The curved portions of the channel define ramp surfaces that at least partially extend into the path of a securing member created by the bore. Thus, when a securing member, such as a bolt, pin, screw, nail or similar object is inserted into the bore to secure the wall anchor to the wall, the securing member contacts the two ramp surfaces, separating the fingers. As the fingers separate, a portion of the fingers near the ramp surfaces deform such that the ramp surfaces rest on an outer portion of the securing member, thus providing a securing force for connecting the wall anchor to the wall and relieving stress on the area at which the fingers are connected to the barrel.
