Abstract:
1. A detachable surrogate top tube assembly for a bicycle comprising: an inner tube member having an insert portion that is telescopically inserted within a receiving portion of an outer tube member, the insert and receiving portions each having a lengthwise centered longitudinal axis that is oriented substantially coincident, one with the other, in a retracted configuration; a first yoke non-rotatably coupled to a first end of the tube assembly; a second yoke non-rotably coupled to a second end of the tube assembly; a first gate assembly coupled to the first end of the tube assembly and having a first end, a second end and a pivot portion, wherein the first end and second end pivot about the pivot portion that is located between the first end and the second end; a second gate assembly coupled to the second end of the tube assembly and having a first end, a second end and a pivot portion, wherein the first end and second end pivot about the pivot portion that is located between the first end and the second end; the insert portion and the receiving portion each having a length; and the insert portion and the receiving portion each having a non-round cross-sectional shape running along a substantial entirety of their lengthwise centered longitudinal axes for a substantial entirety of their lengths with a sufficiently narrow clearance space therebetween such that rotation of the insert portion relative to the receiving portion is limited by abutting interference between an exterior surface of the inner tube member and an interior surface of the outer tube member; wherein the insert portion has a substantially uniform cross-sectional shape along a length thereof and the longitudinal axis centered therein is arc-shaped, and the receiving portion has a substantially uniform cross-sectional shape along a length thereof and the longitudinal axis centered therein is arc-shaped.
