ABSTRACT:
Two hinge members are pivotally mounted about edges of a clamp. Thrust bearings are disposed in recesses in both hinge members for preventing relative movement between the hinge members along the clamp length. Antirotation portions of the bearings resist rotation of the bearings caused by torque produced by the hinge members on the bearings. In one embodiment, the clamp has a longitudinal key that is engaged within a keyway in the bearings that prevents bearing rotation. In another embodiment, the bearings have a longitudinal free extension on at least one side of a bearing body. The extensions increase the effective length of the bearings, limiting rotation. The extensions are preferably meshable with other bearings for transferring torque between adjacent bearings, or bearings may overlap the extensions. More preferably, the extensions are lockable to other bearings. The clamp may have notches extending between its walls and a clamp base such that the clamp base remains unaltered upon bending of the walls. Additionally, the thrust bearings may have lateral free extensions that increase the width of the bearing and that have a smaller width once mounted within the clamp to reduce gaps therebetween.
