Definitions

  • the present invention relates to a pressure adjustable writing instrument for different color leads or inks and, more particularly, to such a writing instrument, for instance pressure adjustable ball point writing instrument, in which by applying pressure upon a push button or pressure spindle, the lead or pen cartridge is moved into its writing position in which it is locked.
  • a writing instrument for instance pressure adjustable ball point writing instrument
  • the lead or pen cartridge is moved into its writing position in which it is locked.
  • further pressure is applied to the push button or pressure spindle so as to slightly further advance said lead or pen cartridge whereby it is unlocked and by means of a spring is returned to its rest position in the interior of the casing of the writing instrument.
  • FIG. 1 is a longitudinal section through a writing instrument according to the invention with four different leads, one lead being shown in its writing position.
  • FIG. 2 illustrates a portion of FIG. l but on a larger scale than the latter.
  • FiG. 3 is a cross section through the -arrangement of FIG. 2 taken along the line III-III thereof.
  • FIG. 4 represents a cross section of the arrangement shown in FIG. 2, said section being taken along the line IV-IV of FlG. 2.
  • FIG. 5 represents a section taken along the line V-V of FIG. 2.
  • the writing instrument according to the present invention is characterized primarily in that the leads are guided by a cylindrical insert which is non-displaceably mounted in the casing or housing of the writing instrument.
  • a rotatable feed spindle provided with two serially arranged cam members, namely a follower cam member and a return member, between which hook-shaped ends of resilient tongues of the lead carrier-s can be adjusted by rotation of the feed spindle for moving the respective lead carrier into writing position.
  • the respective lead carrier can be held in its writing position by means of a spring-urged transverse bolt. When the spindle is advanced further, the respective lead carrier is released and by means of a return spring is returned to its rest position.
  • the arrangement according to the invention furthermore comprises a locking ring non-disp1aceably mounted in the guiding insert.
  • the hook-shaped ends of the resilient tongues of the lead carriers when in rest position will engage said locking ring in such a way that when the feed spindle is moved into its writing position, said resilient hooloshaped ends and tongues will -be retained in their rest position and only the respective adjusted lead guiding means will be moved ⁇ into Writing position.
  • the outer periphery of the guiding insert is provided with a plurality of longitudinal slots corresponding to the number of the lead guiding means, sald resilient tongues of the carriers being inserted into said slots.
  • the rear portion of the guiding insert comprises further continuous slots through which extend the hook-shaped ends of said resilient tongues in such a way that the resilient tongues of the respective lead carrier -being moved will be guided in said slots during its advancing or feed movement.
  • a cylindrical transverse bore Near the front end of the feed spindle there is provided a cylindrical transverse bore in which is guided a transverse 'bolt acted upon by a locking spring.
  • the locking ring is rotatably but axially non-displace ably connected to the feed spindle.
  • the follower cam and the return cam engage slots in the guiding insert so that a rotation of the spindle during its movement into writing position will not be possible.
  • the locking bolt acted upon by a spring will, when occupying its rest position, serve as locking means for the retracted leads while allowing a selection thereof for the movement of a lead into its writing position.
  • the said locking bolt also serves to retain a lead in its Writing position.
  • the construction of the lead advancing mechanism is such that it can be screwed as an entirety into an inner thread of the instrument casing.
  • the writing instrument shown therein comprises a casing l.
  • a guiding insert 21 which has ⁇ a plurality of external axial grooves 20 corresponding to the number of colored lead carriers to be received by said writing instrument.
  • the various color leads or ball point pen cartridges 17 are detachably mounted in carrier members i8 which in their turn are provided with extensions or tongues ll9 ⁇ of resilient sheet metal.
  • the radially inwardly bent hooks 22 ⁇ of the resilient extensions or tongues 19 extend over a rotatably journalled locking ring Z7 which is axially non-adjustably mounted in the guiding insert 2l.
  • Ring 27 rests against an annular abutment 28 of the guiding insert and has one portion thereof provided with an axial milledout portion 29 through which a follower nose or cam 2.4 on a fee-d spindle 3 may pass.
  • the feed spindle 3 has furthermore an yaxial guiding groove 30 engaged by a guiding pin 31 on the locking ring 27 in such Ia way that the spindle may be ⁇ axially displaced along the said guiding pin 3l, while the spindle and ring remain keyed together.
  • Spindle 3 is guided in clip screw 32 cl-osing the rear end of the casing l and is furthermore guided within the guid-v ing insert by means of an abutment nut 34.
  • One side of spindle 3 ⁇ is in addition to the follower nose or cam 24 provided with a return cam 35 which is spaced from follower cam 24 in such a way that the bent-over hook 22 of one of the lead supports can extend between the two cams, when the feed spindle is rotated by means of a push button 23 and is eadjusted for a certain lead.
  • the feed spindle is near the front end thereof provided with a transverse bore 48 in which by means of a pressure spring 317, a locking ⁇ and adjusting bolt 36 with cone-shaped tipi portion is adjustable transverse to the feeding direction of the spindle.
  • the said spring 37 is located in a cylindrical hollow chamber 38 of the locking bolt 36 and rests on one hand against the outer closure closed end of bolt 36 and on the other hand rests against the bottom 39 of the transverse bore 48.
  • a return spring 14 which has both ends guided by extensions 41, 42.
  • the lead carrier or support can be disengaged from writing position by means of an abutment ring or release sleeve as will be described hereinafter.
  • the rear marginal portion 43 of abutment ring il() is shaped conically so as to taper toward the longitudinal axis of said abutment ring 16.
  • the release sleeve is about the same diameter as guiding insert 20 yand when lthe feed spindle retracts, the locking bolt will pass from the release sleeve into the guiding insert without engaging abutment 45, whereby the feed spindle and t-he carrier connected therewith will move to retracted position.
  • the guiding insert 21 is provided with Ia thread 47 so that the entire feeding mechanism can as an entirety be screwed into a corresponding hollow thread of the casing l.
  • lead and ball pen cartridge have been used interchangeably because it is intended to include within the purview of the present invention not only pencils using plural leads but also pens having plural ink supply cartridges.
