Patent

CA 2472873

A two-piece locking fastener which includes a first shaft having a head with a chamfered opening leading into a key way which extends part way down one side of the shaft having an outward taper towards the bottom of the key way, A second shaft is also provided which fits into said vertical key way, preferably having a tapered blunt end at the bottom, which corresponds to the tapered bottom of the key way of the first shaft. Both the key way and the second shaft are specially shaped for proper orientation of the second shaft within the key way. After the first shaft is driven into a medium, the second shaft (which is longer than the groove) is inserted into the key way and then driven downward such that the bottom of the second shaft protrudes outward into the medium at a different angle than the first shaft. One or more friction wedges on the sides of the second shaft cut into the sides of the vertical key way as the second shaft is driven downward, causing firm interengagement between the second shaft and the vertical groove, This interaction helps lock the two shafts together and firmly in place in the medium. Several alternative embodiments are available including rounded and squared spikes, nails, and screws.
