Patent ID: 8046970

Claim:
A telescoping tower comprising: a) a first tower section having a first pressure member mounted on a length of a rung on a flat side of the first tower section and a first overlap region; further comprising a corner member at the end of each rung and the first pressure member mounted between two corner members and b) a second tower section having a second pressure member mounted on a length of a rung on a flat side of the second tower section and a second overlap region and being movable relative to the first tower section from a nested position to an extended position, further comprising a corner member at the end of each rung and the second pressure member mounted between two corner members wherein the space to be occupied by the second pressure member is at least partially common to the space occupied by the first pressure member when in the extended position; c) wherein the second pressure member engages the first pressure member upon movement of the second tower section from the nested position to the extended position such that the first and second pressure members give way relative to each other over the at least partially common space to increase stability of the telescoping tower and reduce unwanted play between the first and second overlapping regions by causing a pressure or force to act between a rung of the first tower section and a rung of the second section on the other flat sides of the first and second tower section respectively; and d) wherein the increased stability at the overlapping regions prevents disengagement of the first and second pressure members through gravity alone.
