Abstract
A toggle member comprising an elongated cylindrical tube having a slot from one end to approximately the center of the tube, defining an opening and channel to receive a fastening bolt; a pivoting threaded bolt engaging with a round ball, the ball threaded to engage the bolt, the ball acting as a pivotally mounted system to allow the bolt to pivot in a manner relocating itself inside and parallel with the tube, said ball being attached to an elastomeric spring bias material tongue fixably seated within the tube so as to exert a spring bias in a direction to force the bolt perpendicular to the tube. The toggle member is meant to be used with a threaded bolt or screw. The elastomeric spring being thinner in the direction facing the bolt entrance allows the bolt to swivel or pivot parallel and into the tube. When the bolt resumes its perpendicular position relative to the tube it is further restricted against the torque exerted by the rotation of the bolt, when the bolt is tightened, by the spring width being greater, in this axis, and having greater strength and moment of inertia, statically restricting the ball from rotating and always keeping it located to its center position withi…
