Claim:
An interlocking frame rail system for boat dock structures, comprising: a first frame rail member including a first side configured for securing the first frame rail member to a first side of a first boat dock structure; a second side opposing the first side and comprising a first aperture; an upper section between the first side and the second side of the first frame rail member; a lower section between the first side and the second side, and below the upper section, of the first frame rail member; an upper channel extending along a length of the first frame rail member; and a lower channel below the upper channel, the lower channel extending along the length of the first frame rail member; a second frame rail member including a first side configured for securing the second frame rail member to a first side of a second boat dock structure; a second side opposing the first side and comprising a second aperture; an upper section between the first side and the second side of the second frame rail member; a lower section between the first side and the second side, and below the upper section, of the second frame rail member; an upper channel extending along a length of the second frame rail member; and a lower channel below the upper channel, the upper channel extending along the length of the second frame rail member; an upper connector member extending along at least a portion of the length of the first frame rail member and at least a portion of the length of the second frame rail member, the upper connector member including a first coupling member extending through the upper channel of the first frame rail member in removable engagement therewith, and a second coupling member extending through the upper channel of the second frame rail member in removable engagement therewith; a lower connector member extending along at least a portion of the length of the first frame rail member and at least a portion of the length of the second frame rail member, the lower connector member including a first coupling member extending through the lower channel of the first frame rail member in removable engagement therewith, and a second coupling member extending through the lower channel of the second frame rail member in removable engagement therewith; and an alignment pin disposed between the second side of the first frame rail member and the second side of the second frame rail member and oriented in an axial direction perpendicular to the second sides, the alignment pin including a first end extending axially into the first aperture, a second end extending axially into the second aperture, and a spacer member between the first end and the second end.
