ABSTRACT:
A ground anchor for channel posts has an angle iron leg driven into the ground with a creased upright fin shroud strip or strap embracing the apex or corner of the angle iron at the trailing end of the leg and secured to the ends of the sides of the angle iron providing a V-shaped socket or barrel. The channel post straddles the angle iron with its side legs bottomed on the sides of the angle iron and a compression member bottomed on the strip forces the channel post against the angle iron to spread the legs of the post into tight gripping relation with the angle iron locking the post in the socket. The socket is open-ended and the post can slide over the angle iron leg to any desired depth so that a sign mounted on top of the post can be positioned at a selected height above the ground. The angle iron is driven into the ground to a depth sufficient to bury the shroud strip so that the post is the only portion of the assembly projecting above the ground. The spreading of the legs of the post places them under tension so that when the post is struck by a vehicle it will only bend at the impact zone, but will shear at the tensioned zone so that no metal will project above ground.
