Definitions

  • This invention relates to ball point pens, and more particularly to a pen casing adapted to hold a plurality of ball point cartridges, and to a control mechanism on the casing for selectively moving each cartridge between a writing position and a retracted position.
  • the invention is concerned with a push button control device on' a ball point pen casing adapted to move one of a plurality of cartridges into the writing position and thereby automatically to retract another cartridge which may have been in the writing position before.
  • An object of the invention isrthe provision of such a control device which is simple in its design and operation.
  • Another object is the provision of a control device composed of parts which are of very simple shapes so that they may be readily produced from plastics or metals by press operations.
  • FIG. 1 shows a ball point pen equipped with the casing of the invention in front elevational axial section
  • FIG. 2 shows an actuating button of the pen of FIG. 1
  • FIG. 3 shows a divider assembly of the pen in a view corresponding to that of FIG. 2;
  • FIGS. 4 to 6 illustrate the cooperation of an actuating button of FIG. 1 with the divider assembly of FIG. 3 when the button moves from the inoperative position shown in FIG. 4 through an intermediate position illustrated in FIG. 6 into the operative position seen in FIG. 5.
  • FIG. 1 there are shown two conventional ballpen cartridges h, h which have flexible tubular ink reservoirs and a ball point mounted on an end of the reservoir.
  • the cartridges are arranged in a pen casing with which this invention is more particularly concerned.
  • the casing has a generally cylindrical main portion b.
  • the ball point of the cartridge h projects axially from The other end of the main portion b isthreadedly connected to a coaxial cap portion i.
  • a portion a is fixed in the open end of the cap i in a diametrical plane.
  • a divider assembly best seen in FIG. 3 is axially secured between the partition a and a radial end face of the barrelportion b in the casing cavity.
  • the divider assembly consists of three rod portions d, d d and a circular disc portion d
  • the four integral divider assemthe divider, the rod portions d, d d and the projections f extend in the plane of the partition, a, as is evident from FIG. 1.
  • the short rod portion d abuts against the partition, and the disc portion d abuts against the bly portions constitute the four sides of an elongated 7 aforementioned radial end face of the barrel portion b.
  • the divider separates two axially coextensive portions of the casing cavity in the cap portion i.
  • Two actuating buttons 0, c are axially slidable in the respective cavity portions between an inoperative position in which the buttons 0, c are axially slidable in the respective. cavity cavity, and an operativeposition illustrated by the button c.
  • an axially elongated rib j projects from the face of the button 0 opposite the button c, and the latter is provided with a corresponding rib j.
  • the dimensions of the ribs j, j are such that they may move in theframe opening y, r without interfering with each other.
  • Each rib has a shallow V-notch j in its outer face for conforming abutting engagement with the less steeply sloping faces of the locking projections 7, h.
  • the inner end j2'0f each rib is wedged-shaped.
  • the cartridges h, h are held in respective recesses of the buttons 0, c, and the buttons are urged toward their inoperative positions by helical compression springs e, e which abut against the disc portion d of the divider assembly and against radial faces of the buttons.
  • the cartridges h, h are guided in their movement between the writing positionillustrated by the cartridge [1' and the retracted position illustrated by the cartridge h in conforming openings of the disc portion d.
  • FIGS. 4 to 6 In the position of the pen illustrated-in FIG. 1, the actuating button 0 of the reacted cartridge h .is in its inoperative position. As shown in FIG.
  • the rib j of the button 0 is located in the outer portion y of the divider opening.
  • the notched outer face of the rib engages the short rod portion of the divider frame under the urging of the spring e.
  • the long rod portions d d are in their relaxed condition in which they are arcuately bent toward each other between the short rod portion a and the disc portion d
  • the steeply sloping faces of the locking projections f, h loosely abut against the wedge shaped inner end of the rib j.
  • the actuating button c of the cartridge h which is in its Writing position is simultaneously in the operative position shown in FIG. 5.
  • the rib j is located in the inner portion r of the frame opening, and the rib is being urged outward by the spring e so that the less steeply sloping faces of the projections 1, f conformingly engage the V-notch in the outer face of the rib j, and axially lock the button 0.
  • a casing for a ball point pen comprising, in combination: I i
  • lock releasing means fixedly fastened on each actuator member and engageable with said locking means for moving the same in said transverse direction away from said lockingpositionthereof when said actuator member moves from said inoperative toward said operative position thereof; and (g) resilient means permanently urging each actuator member to move from said operativetoward said inoperative position thereof, said engagementmeans axially abutting against said locking meansunder. the V urging of said resilientmeans when said actuator member is in theoperative position thereof and said locking means is in said locking position.
  • lock releasing means each include a wedge shaped member camrningly engageable with said locking members for moving the same away from each other.
  • two of said rod members being elongated in an axial direction and being spaced from each other in a direction transverse of said axis;
  • each actuator :button (d) an axially elongated integral rib projecting from each actuator :button into said frame opening for axial movement therein, each rib having (l) a cam face obliquely inclined relative to said directions and engageable with said locking member for resiliently displacing said'locking V member outward of said opening in said transverse direction when said button moves from said inoperative toward said operative position,
  • said disc member I being formed with two openings spaced in said transversedirection; and a cartridge member secured to each of said buttons and slidably received in a respectiveopening-of said disc member for axial movement with the respective button.
