Patent attributes
A cover assembly has a support defining a pivot axis, a cover pivotal relative to the support about the pivot axis between an open position and a closed position, and a torque spring having first and second ends, a biasing coil part from which the first end extends, and a gripping coil part extending from the biasing coil part and from which the second end extends. The first end is seated in the cover, and the gripping coil part, except when is installed or adjusted, frictionally tightly and elastically engages the support and nonrotatably secures the second end to the support against rotation relative to the pivot axis. The gripping coil part is elastically deformable during installation or adjustment to disengage from the support and allow angular or axial movement of the gripping coil part and repositioning on the support.
