Definitions

  • the present invention relates generally to writing devices having two retractible writing elements, and more particularly to twoacolor ball-pens.
  • One object of the invention is to provide a two-color ball-pen or stylograph Lhaving a particularly simple and reliable operating mechanism.
  • Another object of the invention is to provide a very cheap mechanism of the above kind.
  • the invention comprises a cap having at its upper portion a diametrical wall on each side of which may slide the operating knobs of two writing elements movable axially within the cap against a spring, which diametrical wall rotatably carries at its lower portion an oscillating member lhaving two studs protruding laterally and coacting each with a .recess located in each of the operating knobs which, with the exv ception of an assembling groove, are symmetrical relatively to the plane of this wall.
  • each recessfis such that, under action of one of the return springs of the writing elements, the oscillating member may be positively pushed always in the same direction.
  • FIG. 1 is a longitudinal section through the upper portion of a two-color ball-pen according to the invention.
  • FIG. 2 is an longitudinal section thereof on a plane perpendicular to the section plane of FIG. 1.
  • FIGS. 3, 4, 5, 6 and 7 are transverse sections respectively on the lines III-III, IV-IV, V-V, VI-VI and VII-VII (FIG. l).
  • FIGS. 8 and. 9 are diagrammatical detail views showing independently the two operating knobs and the oscillating members, respectively when one writing element is being brought into writing position, and after this operation.
  • FIG. l is an exploded perspective on a large scale showing the two operating knobs and the oscillating member.
  • the two-color ball-pen shown in the drawings comprises a barrel 1 rigidly secured to a cap 2 extending thereabove.
  • the upper portion of the cap 2 ends in a diametral wall 3 extending only in the upper portion of the ball-pen, while the lower portion of the cap 2 has a cylindrical transverse recess adapted to rotatably receive the cylindrical head 4 of an oscillating member 5 engaged therein.
  • the cap 2 is open at the level of the upper portion of the knobs 6, 7. The latter may be pushed against helical return springs 9 located on the cartridges 8.
  • Each spring 9 is compressed between the knob 6 or 7 and an inner thrust ring 10 fixed within the barrel 1.
  • a pocket clip 11 of known type is laterally mounted on the cap 2 with which it is preferably integral, the whole unit being made of plastic.
  • FIG. 10 The face of the knob 6 directed towards the wall 3 is provided with a recess 12 (FIG. 10) having a profile limited at its upper portion by a transverse zone 12a (FIG. 8), which is connected by convergent inclined cam-faces 12b and 12e to a lower end-zone 12d (FIG. 8).
  • the recess 12 is thus limited on one side of the knob 6 by a vertical edge 12e (FIGS. 8 and 9), and on the ,other side by the two Zones 12a, 12d having their ends tangent to an ideal straight line (not shown) parallel to the edge 12e.
  • a groove 13 (FIG. 10) having the same depth as the recess 12, is located above the latter, one side of the groove 13 being in line with the edge 12e.
  • the knob 7 On its face directed towards the wall 3, the knob 7 is provided with a recess 14 (FIG. 10) similar to the recess 12 and symmetrical thereto with respect to the plane of the wall 3.
  • Reference numerals 14a, 1411, 14C, 14d and 14e refer to the elements of the recess 14 respectively corresponding to the elements 12a, 12b, 12C, 12d, 12e of the recess 12 (FIGS. 8, 9, 10).
  • Each yknob 6, 7 hasat its lower portion a boss 15 directed ⁇ towards the ball-pen axis.
  • the thickness of each boss 15 is equal to half the thickness of the wall 3, so that vthe knobs 6, 7 may be both in contact by their bosses 15 (FIGS. 2 and 6), the upper faces 15a of the latter preferably coming into abutment against the lower portion of adequate shoulders 16 provided within the cap 2in Aorder to limit the upward movement of the knobs 6, 7 under action of the return springs 9.
  • the oscillating member 5 with its cylindrical head 4 hinged in the wall 3, has substantially the same thickness as the said wall 3.
  • the lower portion of the oscillating member 5 has two studs 17 and 18 (FIG. l0) protruding laterally on each side in order to cooperate respectively with the recesses 12 and 14 of the knobs 6 and 7 (FIGS. 5 and l0).
  • knob 6 is still pushed down, the latter is locked in writing position as above indicated, the knob 7 being then maintained in retracted position.
  • the groove 13 is adapted to permit assembly of the ball-pen.
  • the knob 7 is rst placed in retracted position, and whereafter the cylindrical head 4 of the oscillating member 5 is engaged through the wall 3, the said oscillating member 5 being moved in a direction perpendicular to the ball-pen axis.
  • the knob 6 is inserted from the inner space of the ball-pen and, due to the groove 13 passing over the stud 17, it is possible to bring the recess 12 around the said stud 17.
  • bosses 15 and shoulders 16 may be replaced by any other known device to limit the upward movement of the knobs 6, 7.
  • a two-cartridge retractable ball pen mechanism comprising a longitudinal housing open at its lower end and at its upper end, and having an inner thrust ring provided with two axial openings; a diametrical wall integral with said housing and extending above the upper end of the latter; two push-knobs inserted in and projecting from the upper end of said housing, each of said knobs being axially movable in said housing and each having a recess on its side facing the other push-knob; two ball-pen writing elements of predetermined color movable axially in said housing through the said openings of the thrust ring, and having their upper ends each mounted in their respective push-knobs, their lower ends each carrying a ball point adapted to project from the lower end of said housing when in operative position; a return spring disposed around each writing element between said thrust ring and the corresponding push-knob to urge the latter into its uppermost position; an oscillating member pivotally carried by the lower portion of the said diametrical wall and adapted to oscillate under the wall and
