Abstract
A bearing assembly is disclosed, which comprises at least two slidable fasteners interengaged with at least two bearing pieces such that the slidable fasteners have substantially unrestricted biaxial motion relative to one another. The bearing pieces are comprised of self-closable fastener film comprising a base sheet and a multiplicity of ribs projecting from the base sheet, wherein the flat side of the first bearing piece is attached to the flat side of the second bearing piece such that the ribs of the first bearing piece are not parallel relative to the ribs of the second bearing piece.
Claims25
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;
- and
- wherein the first and second slidable fasteners have substantially restricted motion in the axial direction perpendicular to the slidable fasteners.
