Abstract:
1. A mounting fixture comprising: a first tubular member having a first end, a second end and a central longitudinal axis extending therethrough; a second tubular member having a first end, a second end and a central longitudinal axis extending therethrough; and an articulation joint coupled between the first tubular member and the second tubular member to position the longitudinal axis of the first tubular member at a desired angle relative to the longitudinal axis of the second tubular member; the articulation joint including: a first monolithic articulation member including a first head and a first post, the first post configured to extend into the first tubular member; a second monolithic articulation member including a second head and a second post, the second post configured to extend into the second tubular member; a first monolithic clamping member including a first head portion and a first post portion, the first post portion configured to extend into the first tubular member; a second monolithic clamping member including a second head portion and a second post portion, the second post portion configured to extend into the second tubular member; a first threaded stud extending through the first and second heads of the first and second articulation members, and including a first threaded end portion having right-handed threads and a second threaded end portion having left-handed threads, the first threaded end portion threadably engaging a threaded bore extending into one of the first head portion of the first clamping member and the second head portion of the second clamping member, and the second threaded end portion threadably engaging a threaded bore extending into the other of the first head portion of the first clamping member and the second head portion of the second clamping member; a second threaded stud including a first threaded end portion having right-handed threads and a second threaded end portion having left-handed threads, the first threaded end portion threadably engaging a threaded bore extending into one of the first post portion of the first clamping member and the first post of the first articulation member, and the second threaded end portion threadably engaging a threaded bore extending into the other of the first post portion of the first clamping member and the first post of the first articulation member; and a third threaded stud including a first threaded end portion having right-handed threads and a second threaded end portion having left-handed threads, the first threaded end portion threadably engaging a threaded bore extending into one of the second post portion of the second clamping member and the second post of the second articulation member, and the second threaded end portion threadably engaging a threaded bore extending into the other of the second post portion of the second clamping member and the second post of the second articulation member; wherein the first post of the first articulation member and the first post portion of the first clamping member are configured to cooperatively exert a radially outward force on an interior surface of the first tubular member; wherein the second post of the second articulation member and the second post portion of the second clamping member are configured to cooperatively exert a radially outward force on an interior surface of the second tubular member; and wherein the first head portion of the first clamping member and the second head portion of the second clamping member are configured to cooperatively exert a compressive force against the first head of the first articulation member and the second head of the second articulation member to clamp the first articulation member from pivotable movement relative to the second articulation member with a clamping surface of the first head portion of the first clamping member engaging a clamping surface of the second head of the second articulation member and a clamping surface of the second head portion of the second clamping member engaging a clamping surface of the first head of the first articulation member.
