    Abstract: In a writing utensil according to the present invention, when a rearward outer cylinder is rotated in either direction, a cam engaging projection, which is integral with the rearward outer cylinder, slides pressingly on either of the respective cam surfaces of first and second sliders. This causes one of the first and second sliders to advance, which in turn causes a first of the first and second refills to project forwardly while the other remains retracted. Similarly, when the rearward outer cylinder is rotated in the opposite direction, the cam engaging projection slides pressingly on the other of the cam surfaces of the first and second sliders. This causes advancement of the other of the sliders, and in turn causes the second of the first and second refills to be projected while the first remains retracted. The construction allows these operations to be smoothly, stably and positively performed.

  • Patent number: 5026190
    Abstract: A dual writing element retractable pen includes coaxial upper and lower barrel members, an upper cylindrical cam part being integrally formed with the upper barrel member and having a bottom cam surface. A matching lower cylindrical cam part telescopes the upper barrel member and is oriented so that the confronting end faces of the cam parts delineate a cam groove having opposite oppositely inclined sections. A rotatable guide member longitudinally slideably supports pen cartridge coupled chucks having followers engaging respective cam groove sections, the guide member being coaxial with the barrel. In one form, the lower cam member is integrally formed with the lower barrel member and, in another form, the lower cam and barrel members are an integrally molded unit and the guide member terminates in an external finger knob.

  • Patent number: 4999017
    Abstract: A writing utensil for three different leads is provided in which due to the use of a special front part and a pusher housing being easily insertable into the same, a conventional writing utensil with only one lead can be converted in a simple and robust fashion to a three-color writing utensil. The pusher housing loosely inserted into the shaft housing, which supports the leads, has a profiled contour and can tilt freely into one of several predetermined tilting positions under the effect of gravity and as a function of the rotary position of the shaft housing in order to bring a selected lead into a ready position from which it can be displaced into the writing position.

  • Patent number: 4948285
    Abstract: A writing instrument in the form of a ball pen has two cartridges capable of being alternately moved into the writing position by rotating the barrel. A provision is made for a space in the top part of the barrel for accommodating or receiving various accessory devices such as stamping mechanisms, marker pens or the like. The invention includes a guide tube housed within the barrel and having two longitudinal slots therein. Two slides having small tubes for receiving the writing cartridges, are movable back and forth on offset guide rails on the guide tube. The slides are forced into contact with a curve switching cam surface of a switching casing by springs. By rotating the switching casing, the one or other slide and thus the small tubes with the writing cartridges inserted therein are alternately pushed toward the bottom of the writing instrument and into the writing position.

  • Patent number: 4904101
    Abstract: A writing instrument has an inner barrel defining a compartment for storing writing leads, an outer front barrel encircling a forward portion of the inner barrel and an outer rear barrel encircling a rearward portion of the inner barrel. The outer rear barrel is angularly displaceable about the inner barrel but not axially displaceable relative thereto. An eraser holder is mounted within the rearward portion of the inner barrel and holds an elongate eraser which can be extended and retracted in response to angular displacement of the outer rear barrel in opposite directions.

    Abstract: A writing instrument comprises a plurality of slots for holding writing implements such as colored leads, the slots being formed radially in the inner wall of a cylindrical body. The instrument comprises a guide tube mounted coaxially within the cylindrical body and having an opening which can be aligned any one of the slots, a cover plate provided at the opening of the guide tube and adapted to be tilted by the operation of a knock cap, and a chuck provided to the front end of the guide tube. A selected writing implement in the slot is allowed to drop by gravity into the guide tube from the tilted cover plate and then is clamped by the chuck.

  • Patent number: 4270869
    Abstract: A composite writing instrument having a lower tubular casing accommodating therewithin two retractable mechanical pencil units spaced by about 180.degree.. An upper tubular casing encloses a cam mechanism for effecting a reciprocal rotational motion through about 180.degree. around the axis of the instrument and engaging both pencil units for alternately shifting them in the axial direction whereby the two pencil units can be alternately advanced to a writing position through an opening at the lower end of the lower tubular casing, or retracted to a retracted position within the lower tubular casing. A feeding operation for advancing the lead of the pencil unit in the writing position is effected by reciprocating of the upper tubular casing in the axial direction.

  • Patent number: 4202641
    Abstract: A mechanical pencil unit of the pushbutton-action type and a ballpoint pen unit are housed in a common holder having top and bottom sections which are rotatable in oppposite directions relative to each other. Mounted within the holder and substantially secured to its bottom section only is a cradle which supports and constrains the two writing units for independent longitudinal motion with respect to the holder. The writing units are spring-biased into sliding engagement with an overhanging, downward-facing cam ledge on the inside surface of the holder top section, such that the writing units are selectively moved from a retracted to a writing position upon manual rotation of the holder top section in either direction relative to its bottom section. Upon movement of the mechanical pencil unit to the writing position, an offset pusher finger extending downwardly from a pushbutton on the holder is moved into alignment with the pencil unit for actuating and making the same ready for writing or marking.
