Abstract:
A locking device for inhibiting movement of an arm relative to a second arm comprising:a) a tubular main shaft body having a longitudinal axis, a first end, an opposite second end and a round cross section, with two opposing apertures near the first end; b) a first hook base plate oriented substantially perpendicular to the longitudinal axis of the main shaft body and rigidly connected to the opposite end and centered over said end of said main shaft body; c) a tubular telescopic shaft body having a longitudinal axis, a first end, an opposite second end, a round cross-section, a diameter adapted for insertion into the first end of the main shaft body having a plurality of aligned opposing pair apertures; d) a second hook base plate oriented substantially perpendicular to the longitudinal axis of the telescopic shaft body and rigidly connected to the opposite end and centered over said end of said telescopic shaft body; e) a first pair of hooks, said pair of hooks positioned at the opposite ends of the outer face of the first hook base plate, said hooks rigidly connected to said first hook base plate in such manner as the said pair of hooks are substantially parallel to the longitudinal axis of the main shaft body and further oriented such that the openings of said hooks are substantially one hundred and eighty degrees from each other, wherein the opening of the first hook is oriented towards to the top edge of the hook base plate and the opening of the second hook is oriented towards to the bottom edge of the hook base plate; f) a second pair of hooks, said pair of hooks positioned at the opposite ends of the outer face of the second hook base plate, said pair of hooks rigidly connected to said second hook base plate in such manner as the said pair of hooks are substantially parallel to the longitudinal axis of the telescopic shaft body and further oriented such that the openings of said hooks are substantially one hundred and eighty degrees from each other, wherein the opening of the first hook is oriented towards to the top edge of the hook base plate and the opening of the second hook is oriented towards the bottom edge of the hook base plate; g) whereby the opening of the first hook of the first hook pair is substantially one hundred and eighty degrees relative to the opening of the first hook of the second hook pair and the opening of the second hook of the first hook pair is substantially one hundred and eighty degrees relative to the opening of the second hook of the second hook pair; h) whereby the hooks of each end of the device are interchangeably adapted to extend on two sides of said arm and said second arm; i) whereby the said main shaft and said telescopic shaft are rotated to engage said hooks on said arm and said second arm; j) whereby apertures of both shafts align to receive a locking device therethrough to prevent rotation or any telescoping movement of the shafts; and k) thereby preventing any movement of the arm toward or away from the second arm.
