  • Retractable ball-point pen
    Patent number: 5997204
    Abstract: An operating mechanism of a retractable ball-point pen including a ring mounted over a pin. The pin has at one end thereof a push button and at the other end thereof a portion having a greater diameter. Additionally, the pin has at least one pair of ribs which interact with grooves and saw-toothings on at least one end of the ring. The ends of the ribs are preferably provided with inclined lifting surfaces. To facilitate assembly, the saw-toothings may be symmetrically formed such that the direction of insertion into a pen housing is not critical. Preferably, the saw-toothings of the ring extend only over an inner partial portion of the wall thickness of the ring and the outer partial portion of the wall thickness of the ring forms a plane end face. A pen housing in which the operating mechanism may be positioned has axially extending supports configured to support the ring, preferably by engaging the plane end face of the ring.
