Abstract:
1. An interlocking fence system comprising: first and second spaced-apart upright posts attached to a grade; a tubular locking rail and an alignment rail extending between the first and second posts; a picket with a transverse profile and a locking slot extending inwardly from a side surface thereof, wherein the picket passes through the rails at a locking aperture and is then pivoted into alignment with an axis of a plurality of spaced apart, coaxial alignment apertures; the plurality of alignment apertures in the rails comprising-at least one alignment aperture in the alignment rail and at least one alignment aperture is formed in a lower surface of the tubular locking rail, wherein the alignment apertures have a profile matching the transverse profile of the picket and are in upright alignment with respect to an axis of the picket to restrict lateral movement of the picket; and the locking aperture formed in the locking rail spaced from the alignment apertures and having a profile matching the transverse profile of the picket to receive the picket at an angle offset from an axis of the alignment apertures for assembly, wherein the locking aperture is offset laterally with respect to the axis of the picket, wherein the lateral offset of the locking aperture defines a tab inserted into the locking slot with the picket aligned by the alignment apertures.
