Abstract:
1. A pylon attachment device for coupling a pylon to a floor joist, said attachment device comprising: a bearing plate for fixed attachment to said floor joist; a plurality of biasing members, each biasing member having a first end operatively coupled to said pylon and a second end operatively coupled to said bearing plate to allow said bearing plate to move relative to said pylon in a direction generally perpendicular to an imaginary center axis of said pylon and then return to a preset position; wherein said plurality of biasing members are equi-angularly positioned about said imaginary center axis of said pylon; wherein at each said biasing member is a dampened biasing member that includes at least one item selected from the group consisting of a hydraulic dampener and a pneumatic dampener; a cap lowerly adjacent said bearing plate; a shear pin extending from said cap to said bearing plate to maintain said bearing plate at said preset position until a predetermined amount of force shears said shear pin and allows said bearing plate to move relative to said pylon in a direction generally perpendicular to said imaginary center axis of said pylon; a support ring fixedly coupled to said pylon, and wherein said first end of each said dampened biasing member is pivotably coupled to said support ring; a telescoping member telescopically coupled to said pylon and being movable along said imaginary center axis of said pylon, said telescoping member having an upper end coupled to said cap; and means for biasing said telescoping member to a preset position relative to said pylon.
