Abstract
A moulded plastics article having a closed bore to receive a spindle, the bore being formed with at least one radially inwardly projecting annular rib adapted to locate in a circumferential groove in the spindle, characterized in that the or each rib is interrupted to form a gap for the passage of fluid from one side of the rib to the other when the spindle is inserted into the bore.
Claims10
A moulded plastics article having a closed bore for receiving a spindle, said bore being formed with at least one radially inwardly projecting annular rib, said rib being adapted to locate in a circumferential groove in the spindle, wherein the or each said rib is interrupted to form a gap for the passage of fluid from one side of said rib to the other when the spindle is inserted into said bore.
A castor wheel having a closed bore for receiving a spindle which has a first circumferential groove, wherein said castor wheel has in said bore a first radially inwardly projecting rib which is positioned and dimensioned to fit in said first groove when the spindle is inserted in said bore and wherein said first rib is interrupted to leave a gap in the circumference thereof to allow for the axial passage of fluid from one side of said rib to the other through said gap when the spindle is inserted in said bore and the rib fits in said groove, said gap extending circumferentially over a distance which is small as compared with the circumferential extent of the rib.
A assembly comprising a castor wheel having a closed bore and spindle which has a first circumferential groove, wherein said castor wheel has in said bore a first radially inwardly projecting rib which is positioned and dimensioned to fit in said first groove when the spindle is inserted in said bore and wherein said first rib is interrupted to leave a gap in the circumference thereof to allow for the axial passage of fluid from one side of said rib to the other through said gap when the spindle is inserted in said bore and the rib fits in said groove said gap, said gap extending circumferentially over a distance which is small as compared with the circumferential extent of the rib.
