Abstract
A hybrid eccentric wedge anchor includes a cylindrical anchor body, an eccentric wedge unit, and cylindrical leading end. The eccentric wedge unit includes a tapered body, a shoulder between the tapered body and the anchor body, and a crescent shaped clip rotatably positioned around the tapered body. The longitudinal axis of the tapered body is different from the longitudinal axis of the anchor body. The shoulder varies in width around the circumference of the anchor body. As the crescent shaped clip rotates around the tapered body, its outer circumference varies from being flush with the outer circumference of the cylindrical anchor body to extending beyond the outer circumference of the cylindrical anchor body. The hybrid eccentric wedge anchor can be configured in many useful anchor forms having the eccentric wedge unit. Examples include, but are not limited to, expansion bolt or drop-in configurations.
