发明名称 Tethered flying disc with two-piece bearing means
摘要 A tethered flying disc toy having a conventional inverted saucer body and an elongated flexible tether attached to the body by an annular ball bearing providing full freedom of rotation of the disc relative to the tether. In another form, the tether line slides through a bore in an upwardly projecting shank of a plug inserted into the inner race of a ball bearing having an axis of rotation coincident with the axis of rotation of the disc body so that the disc can move freely along the tether line while spinning.
