Patent ID: 7374468

Claim:
A construction system comprising: an elongated connection stem extending between free tip ends and having an outer peripheral surface and a longitudinal axis and including: a central member having a uniform first dimension transverse of the longitudinal axis; opposed end members integral with the central member, each having a uniform second dimension transverse of the longitudinal axis greater than the first transverse dimension, each opposed end member having a longitudinal slot formed into the outer peripheral surface extending from its associated free tip end toward the central member; and an attachment member having a central through bore slightly smaller than the second transverse dimension of each of the end members; a cross section of each of the end members perpendicular to the longitudinal axis being of similar shape to that of the central through bore and being slightly larger in size than the central through bore; and a cross section of the central member perpendicular to the longitudinal axis being of similar shape to that of the central through bore but of smaller size than the central through bore; whereby, in one instance, the attachment member can be fittingly received, via the central through bore, on either of the opposed end members and, in another instance, the attachment member can be slidably received, via the central through bore, on the central member.
