Abstract: A rolling flexure bearing. The bearing is formed of a thin sheet of elastic material that is attached to a surface of a first object. The sheet extends a short distance along the surface of the first object. The sheet then makes a 180 degree elastic bend off the surface of the first object to reverse the direction of the sheet. After making the bend, the sheet then extends a short distance along the surface of the second object substantially parallel to the surface of the first object. The sheet is attached at its end to the surface of the second object.In this configuration, the flexure bearing is stiff along an axis parallel to the bend axis to constrain movement along this axis. The flexure bearing, along the axis normal to the surfaces of the objects, has a high compliance rate to provide damping between the objects. Along the third orthogonal axis, normal to the bend axis, the bearing allows free relative movement between the two objects, until it approaches either of the two attachment areas.

The clip may be preassembled to the bushing before the crank pin is inserted through the bushing. If so, as the crank pin is inserted through the bushing, a pilot portion on the crank pin is effective to radially spread the clip until a retaining groove on the crank pin becomes aligned with the clip.

The crosspiece is made of elastomeric material formed with forward sloping faces and associated radial, inwardly directed lugs shaped to be retained in the latch groove. When the spool is inserted onto the shaft the lugs drop into the latch groove to releasably retain the spool on the shaft. To remove the spool, the push button is depressed causing ramp faces thereon to engage the sloped faces of the crosspiece and withdraw the lugs from the groove freeing the spool for removal over the end of the shaft.
