ABSTRACT:
A concealable anchor which can be buried or cemented in the ground such that the top end thereof is flush with ground level, wherein the anchor has an elongated tubular pipe which is open on both its top and bottom ends, and an attachment chain fixedly connected at one end to the exterior surface of the bottom end portion of the tubular pipe. The chain extends through the opening in the bottom end of the tubular pipe into the inner confines thereof. The other end of the chain is connected to a removable end cap which seats upon and covers the open top end of the tubular pipe. The attachment chain is of sufficient length such that it may be pulled outwardly from within the pipe through the open top end thereof for attachment of an object thereto, when desired. The attachment chain is constructed such that it may also retract into smaller compass for storage within the tubular pipe when the anchor is not in use.
