SUPPORT ANCHOR

Japanese Patent JPS6175123

A

A ground anchor (10) for channel posts (11) has an angle iron leg (19) driven into the ground with a creased upright fin shroud strip (21) embracing the apex or corner (26) of the angle iron (19) at the trailing end of the leg (19) and secured to the ends (27) of the sides (25) of the angle iron (19) providing a V-shaped socket (29). The channel post (11) straddles the angle iron (19) with its side legs (15) bottomed on the sides (25) of the angle iron (19) and a compression member (31) bottomed on the strip (21) forces the channel post (11) against the angle iron (19) to spread the legs (15) of the post (11) into tight gripping relation with the angle iron (19) locking the post (11) in the socket (29). The socket (29) is open-ended and the post (11) can slide over the angle iron leg (19) to any desired depth so that a sign (12) mounted on top of the post (11) can be positioned at a selected height above the ground. The angle iron (19) is driven into the ground to a depth sufficient to bury the shroud strip (21) so that the post (11) is the only portion of the assemply projecting above the ground. The spreading of the legs (15) of the post (11) places them under tension so that when the post (11) 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.
