Abstract:
1. A bearing assembly, comprising: a reclosable fastener film comprising a base sheet and a multiplicity of parallel ribs projecting from the base sheet to form a first slidable fastener; a reclosable fastener film comprising a base sheet and a multiplicity of parallel ribs projecting from the base sheet to form a first bearing piece; a reclosable fastener film comprising a base sheet and a multiplicity of parallel ribs projecting from the base sheet to form a second bearing piece; and a reclosable fastener film comprising a base sheet and a multiplicity of parallel ribs projecting from the base sheet to form a second slidable fastener; wherein a bearing is formed when the flat side of the base sheet opposite the ribbed surface of the first bearing piece is connected to the flat side of the base sheet opposite the ribbed surface of the second bearing piece such that the ribs of the second bearing piece are not parallel to the ribs of the first bearing piece; wherein the ribs of the first bearing piece are interengaged with the ribs of the first slidable fastener and the ribs of the second bearing piece are interengaged to the ribs of second slidable fastener such that the second slidable fastener is not parallel to the first slidable fastener; wherein the first and second slidable fasteners have substantially unrestricted biaxial motion relative to one another; wherein the first and second slidable fasteners have substantially restricted motion in the axial direction perpendicular to the slidable fasteners; and wherein at least the topmost portion of the ribs includes a friction-reducing agent to facilitate interengagement of the slidable fasteners with a bearing piece.
