Patent ID: 11280104

Abstract:
A device is disclosed for facilitating the anchoring and release of a structure to a medium, such as sand. The device is operable to inject a liquefying fluid into a medium upon a down stroke so as to facilitate liquefication within an area of the medium. The structure is simultaneously inserted into the area of the medium where liquefication has occurred by creating a vacuum within the structure, upon an upstroke, which facilitates the insertion operation. The distal end of the structure to be anchored is fitted with at least one protrusion for increasing the holding force of the medium. If desired, the distal end of the structure is also fitted with at least one fin operable under selective control of a user for reducing the holding force on the structure. In one embodiment, the user, when desiring to release the structure, rotates the structure, thereby rotating the fin. The fin, rotating within the liquefied medium, serves to reduce the holding force of the medium with respect to the structure, thereby allowing for easier removal of the structure by a user.
