    摘要： A detachable luggage caster roller for suitcases, luggage and the like is comprised of a roller support bracket formed of synthetic resin and including a cylindrical male member and a base plate adapted to be secured directly or indirectly through a seat member to the luggage and formed of synthetic resin, said base plate including a cylindrical female member adapted to be slidably engaged, directly or indirectly with said cylindrical male member of said roller support bracket through point and line contact. The roller is formed of different kinds of synthetic resin and comprised of a tread reinforced by a bridge-shaped rib embedded therein and a sleeve bearing formed of synthetic resin impregnated with lubricating oil.

    摘要： A combination thrust and radial bearing including inner and outer housing members. Each housing member includes a longitudinally extending portion and a radially outwardly extending portion. A bearing insert made from synthetic resin is positioned between the housing members and includes a longitudinally extending portion having radially extending ribs thereon, and a radially outwardly extending portion having longitudinally extending ribs thereon. The ribs reduce the contact area, and therefore, the friction between the insert and the adjacent components of the bearing.

    摘要： There is provided a mounting assembly for connecting a wheel fork to a walker apparatus. The assembly comprises a frame portion of the walker apparatus having an upper bore, lower bore, and passageway extending between and positioned radially inwards relative to the bores. The frame portion has a first annular seat located between the upper bore and the passageway. A second annular seat is located between the lower bore and the passageway. The mounting assembly comprises a shaft assembly having a threaded upper end and an annular shoulder positioned below and extending radially outwards relative to the upper end. The annular shoulder is shaped to abut the second annular seat. The shaft assembly includes a lower portion spaced-apart from the upper end and rotatably connecting to the wheel fork. The mounting assembly comprises a connecting member threadably engageable with the upper end and abuttable with the first annular seat.
