Patent ID: 7780148

Claim:
A drift fence, comprising: an upstanding central post; about six upstanding walls each directly connected to the upstanding central post and disposed in radial relation thereto; each of the about six walls terminating at a free radially outermost end post having a lower end mounted into a ground surface; each wall of the about six walls being formed by a plurality of upstanding, imperforate slat members disposed in spaced apart, lateral relation to one another wherein a transverse cross-section of each slat member is in a triangular configuration; each slat member being connected to an adjacent slat member by a weaving wire attached to one side of the triangular cross-section of the slat member; each slat member having a hypotenuse side that is oriented about 45 degrees to the weaving wire; whereby the lateral spacing and the triangular cross-section eliminate parallel surfaces between adjacent sides of adjacent slat members to generate vortices as a depositional force to accrete wind-blown sand that is blown between the slats.
