Claim 3:
4. An orthodontic appliance as claimed in claim 2, and wherein the multiple section, elongated, telescoping assembly further comprises an outer, cylindrically shaped tube having opposite first and second ends, inwardly and outwardly facing surfaces, and a longitudinal axis which extends between the opposite first and second ends, and wherein the inwardly facing surface of the outer, cylindrically shaped tube defines an internal cavity which extends between the first and second ends thereof;
a first attachment member made integral with the outside facing surface of the outer, cylindrically shaped tube, and which has a distal second end which is positioned laterally outwardly relative to the cylindrically shaped tube, and wherein an aperture is formed in the distal end of the first attachment member, and is sized so as to allow the distal end of the first portion of one of the fasteners to pass therethrough, and wherein the first attachment member is oriented within the gap that is defined between the second portion of one of the fasteners, and the main body of the respective archwire couplers, and where the first attachment member rotates freely about the gap;
a first, intermediate tube which is defined by an elongated main body, and which further has opposite first and second ends, and an outside and inside facing surface; and wherein the inside facing surface of the first intermediate tube defines an internal cavity extending between the first and second ends thereof, and wherein the first intermediate tube is telescopingly received within the internal cavity which is defined by the outer, cylindrically shaped tube, and is further reciprocally moveable relative thereto;
a second, intermediate tube which is defined by an elongated main body, and which further has opposite first and second ends, and an outside, and inside facing surface; and wherein the inside facing surface of the second intermediate tube defines an internal cavity extending between the first and second ends thereof, and wherein the second, intermediate tube is telescopingly received within the internal cavity of the first, intermediate tube, and is reciprocally moveable relative thereto;
an inner, elongated rod having a main body, and which further has opposite first and second ends, and an outside facing surface, and wherein the inner elongated rod is telescopingly received within the internal cavity of the second, intermediate tube, and is further reciprocally moveable relative thereto; and
a second attachment member which is made integral with the second end of the inner elongated rod and which further defines an aperture which is sized so as to allow the distal end of the first portion of another one of the fasteners to pass therethrough, and wherein the first attachment member is received in the gap that is defined between the second portion of the fastener, and the main body of the respective archwire couplers, and rotates freely about the gap, and wherein the first and second attachment members are individually affixed to one of the pair of archwires by way of the respective archwire couplers, and individual cooperating fasteners.
