Definitions

  • the hinged plate or swinging door for engaging the selected writing tip.
  • the selector responds to gravity or inertial forces. Any suitable mechanism can keep the writing tip projected.
  • the push button or clip Upon retraction, the push button or clip is retracted further than the writing tip to free the swinging door from engagement with the writing tips so that any new selection can be made by the hinged selector swinging to the desired writing point.
  • FIG. 1 is an elevation view in full section of a writing instrument showing one writing tip projected to a writing position.
  • FIG. 2 is an elevation view in full section taken along the line Il-II of FIG. 1 and showing the upper part of the writing instrument.
  • FIG. 3 is an elevation view in full section similar to FIG. 2, but showing the glide holding the writing tip in a retracted position.
  • FIG. 4 is an exploded view in three dimensions of the clip, blade, swinging door selector, glide and retraction retainer of FIGS. 1 through 3.
  • FIG. 5 is a sectional view along the line VV of FIG. 4 on an enlarged scale showing the lug that interconnects the blade and the clip.
  • FIG. 6 is a sectional view along the line VI-VI of FIG. 1, but on an enlarged scale, showing the structure for retaining a writing cartridge within a glide.
  • FIG. 7 is an elevation view partly in section of the cap portion of a modified form of the invention wherein the point projection mechanism has a sliding button on the exterior of the cap.
  • FIG. 8 is an elevation view of the modification of FIG. 7 showing the bayonet slot for selectively holding a writing tip in a projected position.
  • FIG. 9 is an elevation view partly in section of the cap portion of a modified form of the invention wherein the point projection mechanism is actuated by a push button.
  • a pen 10 has a cartridge 12 having a writing tip 14 projecting from an opening 16 in a barrel 18.
  • a second cartridge 20 is retracted within the barrel 18 and within a cap 22.
  • the cap and barrel are joined by a connector sleeve 24 which may have a threaded or a friction fit connection.
  • Each cartridge 12 and 20 is held at its upper end by identical glides 26 and the connection to the glides (FIG. 6) allows angular movement as illustrated in FIG. 1.
  • FIG. 1 the cartridge 12 is projected because its glide 26 is engaged by a hinged selector plate or swinging door 28 which may be connected to a push button or sliding clip or other projecting mechanism.
  • the swinging door fits within a cut out portion 30 in the glide 26, and this cut out has an inclining contact surface 32.
  • the provision of surfaces 32 that incline away from the line of contact between the glides prevents the door 28 from straddling the line and projecting both tips.
  • the swinging door 28 is mounted on two apertured ears 34 and 36 that are formed on a sliding blade 38 which, in turn, is reciprocated within the cap 22 by a sliding clip 40 projecting into a cap sidewall slot 42.
  • the blade is formed of stiff material such as sheetmetal and the ears are bent inwardly. Pro jecting from the door are pins 44 that fit within the apertured ears 34 and 36.
  • the glide 26 is urged upwardly by a compression spring 46 resting on the connector sleeve 24.
  • the clip 40 maintains the writing tip 14 projecting from the body, by means of a clip ball 48 having a flat 50 (on its upper end) engaging the cap wall 22 at sidewall aperture 52.
  • the upper end of the clip 40 slidingly engages a cap projection 58, rotating the ball end tightly against the cap 22 to strongly grip fabric'of a pocket.
  • Another structure to increase the gripping action of the clip ball 48 is a second cap projection 60 against which the ball 48 rests in its retracted position shownin FIG. 3.
  • the user of the instrument tilts the instrument to cause the hinged selector plate 56 to swing to the desired glide that is next to be projected. If the writing tips have different colored ink, colored spots 62 on the clip indicate the selected color.
  • the selector door 28 must be free to swing and therefore the blade 38 must be moved upwardly after the glides are at rest. This is conveniently accomplished by connecting the blade to an intermediate point in the compression spring 46.
  • the blade 38 has formed on its lower end a tube 66 (FIGS. 4, 2 and 3) having an inwardly projecting prong 68 disposed between turns in the coil spring 46. One spring thus moves different pieces different distances.
  • a tongue 70 Formed on blade 38 between the hinge ears-34 and 36 is a tongue 70.
  • a lug 72 Projecting from the clip 40 is a lug 72 having an aperture 74 therein '(FIG. 5). The lug 72 is pressed into cap slot 42 and pulled downwardly until the blade tongue enters the lug aperture 74.
  • the tongue may have a barb 76 that locks the lug 72 to the tongue 70.
  • Projecting from the clip 40 are a pair of ribs 80 which limit upward movement of the clip 40 and the blade 38, but only after it and the blade 38 have moved slightly past the retracted position of the glides. The ribs 80 also track the clip in its slot 42.
  • FIG. 6 Shown in FIG. 6 is the connection of the cartridge 12 to the glide.
  • a bore 82 in the glide has inwardly projecting pimples 84 that press against the cartridge and frictionally hold it like a socket while allowing limited angular movement between cartridge and glide.
  • FIGS. 7 and 8 Illustrated in FIGS. 7 and 8 is a slide button 86 connected to a blade 38a that has a swinging door selector (not shown) connected to it.
  • the button slides downwardly in a bayonet shot 88 against the compression of a spring (not shown) which locks the blade 38a in the tip-projecting position.
  • the writing instrument is retained in a pocket by a stationary clip 40a which may have a color spot 62a on the clip for the writing tip selected or a cap spot 63.
  • FIG. 9 Illustrated in FIG. 9 is a cap having a reciprocating push button 102 connected through a slot 104 to a blade 3812 on which may be hinged a door selector (not shown) operating similarly to FIGS. 1 through 4.
  • a color spot 62b may indicate the color of the writing tip selected. Any well-known mecahanism may be employed to keep the writing tip extended and then retracted by operating the button .102.
  • the invention has been described with reference to two generally semi-cylindrical glides 26. It will be appreciated that three or more glides with individual writing tips could be used as long as they have a surface against which the swinging door can bear. Means to hold the glides retracted can be located at any point in the length of the instrument;
  • a writing instrument having a plurality of writing tips comprising;
  • a body member elongated on an axis
  • a plurality of glides mounted on the body member for movement generally parallel to the axis;
  • a manually movable projector mounted on the body for axial movement for projecting writing tips
  • a m ulti-tip writing instrument as set forth in claim 1 having means for releasably holding the selected tip in a projected position.
  • a writing instrument as set forth in claim 1 wherein a compression spring mounted on the bodyengages the glides to normally urge them to a tipretracted position, and the projector contacts the same spring but at a point on the spring that retracts the projector more than the glides, to move the swinging door off of the glides so that it freely swings for a new selection of glides.
  • a writing instrument as set forth in claim 1 wherein there are two glides in sliding contact with each other and the surface of each glide contacted by the swinging door is angled away from the place of contact of the glides, so that the door will not straddle the contact line and instead be disposed positively on one glide or the other.
  • detent means are provided for releasably holding the glides in a tip-retracted position so that only the selected glide will have its writing tip projected for writ- 9.
  • detent means are provided for releasably hold ing the glides in a tip retracted position, and the swinging door is located between the writing tip and the glide holding means, and the glides have a cut out area to accommodate the swinging door and to provide a place of contact between the glides and the door.
  • a writing instrument as set forth in claim 1 having a clip for retaining in a pocket, and the writing tips make different colored writings and the color designation is coded on the clip ball to indicate the color selected by the swinging door, when that color code is uppermost when the instrument is somewhat horizontal, and the clip ball is recessed in the pen body when a writing tip is projected, requiring release of the clip ball and swinging door before a color selection canbe made.
  • a clip reinforcing structure comprising a bulge in the cap, and a clip extension at the end of the clip opposite the ball, whereby sliding the clip disposes the clip extension on the bulge to reinforce the clipping action of the clip.
