Special reusable anchor

Abstract

A special anchoring device called a SPECIAL REUSABLE ANCHOR. This device is used to mount and secure various objects to a structure of masonry, concrete, wood, metal, gypsum wallboard, and the like. After the secure connection or attachment, the device may be released and reused if desired. This removal does not damage or weaken the structure or anchor device. The device is comprised of several structural members namely a fastener with various top portions or “heads”; a free wedge portion with a non-threaded aperture; and, a threaded wedge means for securing and connecting the SPECIAL REUSABLE ANCHOR to a structure. While the three main members are securely connected to the structure, the overall device has a means to release and reuse the SPECIAL REUSABLE ANCHOR for other connections without significant damage to the structure.
