Definitions

  • the present disclosure relates to the field of writing devices. More specifically, the present disclosure relates to writing devices with a writing tip that can be extended and retracted.
  • Writing instruments comprising a barrel and a writing tip that can be extended outside the barrel for wrtiting purpose when a user actuates a writing tip extension-retraction system inside the barrel and retracted inside the barrel when the user does no longer need to use the writing instrument are largely known.
  • the present disclosure aims to address one or more problems in the prior art.
  • the present disclosure relates to a writing instrument.
  • the writing instrument comprises a barrel having a longitudinal axis, a writing tip, and a writing tip extension-retraction system configured to slide axially inside the barrel between a first extended forward position wherein the writing tip extends outside the barrel and a second retracted rearward position wherein the writing tip is retracted inside the barrel from the first extended forward position along an axial rearward direction.
  • the writing instrument further comprises a locking system movable between a locked position wherein the locking system is engaged with the writing tip extension-retraction system in the first extended forward position to lock the latter in this position and an unlocked position wherein the locking system is disengaged from the writing tip extension-retraction system.
  • the writing tip extension-retraction system comprises a movable unlocking member configured to be moved in the axial rearward direction when the writing instrument is moved from a writing position to a rest position, wherein the rest position is a horizontal position or a position with the writing tip oriented upwardly relative to the floor, the movement of the movable unlocking member in the axial rearward direction causing the locking system to move from the locked position to the unlocked position under magnetic attraction between the movable unlocking member and at least one permanent magnet associated with the locking system.
  • the writing tip extension-retraction system may be easily and reliably caused to move to a second retracted rearward position by merely moving (through a user) the writing instrument to an horizontal position or a position with the writing tip oriented upwardly without carrying out any other action such as exerting an effort on an actuation member, e.g. pulling, pressing etc.
  • An horizontal position or a position with the writing tip oriented upwardly or facing up may be considered as a rest position; i.e. a position in which the writing instrument is no longer configured for writing purpose.
  • the horizontal orientation or upward orientation is defined relative to the floor or ground or a lying surface or support, e.g. a table, on which the writing instrument can be laid down in a rest position.
  • the upward orientation of the writing tip more particularly defines an orientation that is opposed to the floor/ground (or a lying surface or support) where the writing tip faces up with respect to the floor/ground.
  • the writing tip of the writing instrument would, in contrast, be oriented downwardly if it were facing the floor/ground or a lying surface or support.
  • the retraction movement may be automatically achieved through re-orienting the writing instrument as described above, in particular through lifting the writing tip upwardly. More particularly, the natural movement of the user after writing is to lift the writing tip from the writing surface and positioning the writing instrument either horizontally or even with the writing tip facing up.
  • the gesture of the user may cause a metallic or magnetic member (movable unlocking member) to move relative to the writing instrument and, notably the locking system thereof, thereby causing unlocking of the latter thanks to the displacement of the metallic or magnetic member and magnetic coupling with the at least one permanent magnet associated with the locking system.
  • a metallic or magnetic member movable unlocking member
  • the locking system comprises a first part configured to be engaged with the writing tip extension-retraction system and a second part that is:
  • the second movable part is moveable between a first forward position wherein it is subject to forwardly oriented pressure forces and at least one second rearward position wherein it is no longer subject to forwardly oriented pressure forces, the first part being kept engaged with the writing tip extension retraction system in the locked position as long as the second movable part is in the first forward position, the movement of the movable unlocking member causing the second movable part to move from the first forward position to the at least one second rearward position.
  • the locking system comprises a trigger member which comprises the first part configured to be engaged with the writing tip extension-retraction system.
  • the trigger member has an head which is the first part of the locking system and a tail.
  • the trigger member or at least the head thereof is able to pivot about an axis that is perpendicular to the longitudinal axis of the barrel.
  • the tail is the second movable part.
  • the writing instrument comprises an actuation mechanism movable between a first forward position wherein it is active and configured to exert forward pressure forces through a first biasing member on the tail in order to maintain the latter in the first forward position and a second rearward position wherein the actuation mechanism is no longer active and a second biasing member is configured to exert rearward pressure forces on the tail.
  • the movable unlocking member is a metallic or magnetic member configured to be moved rearwardly when the writing instrument is moved to an horizontal position, thus creating magnetic attraction between the metallic or magnetic member and the actuation mechanism, which causes the latter to be inactive and the trigger head to pivot and disengage from the writing tip extension retraction system.
  • the locking system further comprises a locking member that is part of the writing tip extension-retraction system and configured to engage with a fixed inner part of the writing instrument, thereby defining two different locking zones.
  • the locking member has a permanent magnet.
  • the movable unlocking member is metallic or magnetic .
  • the writing instrument comprises a lateral housing fixed to the barrel and the movable unlocking member is configured to slide axially within the housing.
  • the housing has an inner forward portion that is tapered toward a forward most end of the housing.
  • the movable unlocking member moves rearwardly and passers-by the permanent magnet, thereby creating magnetic attraction between the movable unlocking member and the permanent magnet, which drives the latter rearwardly together with the locking member, thus disengaging the locking member from the fixed inner part of the writing instrument and disengaging the trigger head from the writing tip extension retraction system.
  • the writing instrument comprises a biasing member configured to bias the writing tip extension retraction system in the rearward direction.
  • the biasing member is configured to exert biasing forces on the writing tip extension-retraction system which are compensated by counter forces generated at the two different locking zones where the writing tip extension retraction system is locked.
  • Figure 1A is a schematic overall view of a writing instrument oriented in a writing position, i.e. oriented obliquely when handled by a user for writing purpose.
  • the writing instrument may be a marker, a felt pen, a highlighter, a ball point pen, a permanent or non-permanent marker or any other type of writing instrument with an extension and retraction mechanism for extending and retracting a writing tip of the instrument when necessary.
  • the writing instrument 10 may comprise a barrel or tubular body 12 having a longitudinal axis X.
  • the tubular body may be a unitary body, or may comprise multiple components.
  • Figure 1A a portion of the length of the barrel has been withdrawn to show the internal mechanism involved in the present disclosure.
  • the writing instrument 10 may comprise at a first forward end of the instrument a tip component 14 comprising a writing orifice 14a which is located at the distal end of the tip component 14.
  • the writing instrument 10 may comprise at a second opposed rearward end of the instrument a clip 16 for clipping the instrument onto a support, a piece of clothes etc.
  • the clip may be actuated by a user, e.g. by pressing the latter with a finger (e.g. the thumb) forwardly along the axis X so as to cause extension of the writing tip of the instrument through the writing orifice 14a in a known manner.
  • acuating members may alternatively be used for causing writing tip extension.
  • the writing instrument 10 may further comprise in the tubular body a tank (not shown in Figure 1A ) for storing a writing ink used by the writing tip.
  • the writing instrument 10 may further comprise a filler cap 18 disposed between the barrel 12 and the clip 16 ( figs. 1A and 1D ).
  • the clip 16 may be firmly engaged around the protruding end of the filler cap 18 so as to cover the latter as shown in figure 1D .
  • the barrel 12 may extend longitudinally from the tip component 14 toward the rear part of the instrument where the clip 16 is located. As shown in figures 1D and 1E , the barrel 12 may extend longitudinally in a rearward direction so as to cover as a sheath the internal components of the writing instrument, including a forward end of the filler cap while leaving the clip 16 uncovered.
  • the writing instrument 10 may comprise, within the barrel 12, a writing tip extension-retraction system or mechanism 20 that is configured to slide axially (along axis X) inside the barrel between a first extended forward position wherein the writing tip 20 extends outside the distal writing orifice 14a ( figures 1A and 1D ) and a second retracted rearward position illustrated in figure 1E in which the writing tip 22 has been retracted inside the barrel along an axial rearward direction (arrow R on figures 1A and 1D ) from the first extended forward position of figures 1A and 1D .
  • the writing tip extension-retraction system 20 may further comprise other internal components such as a nib 24 of which a first end forms the writing tip 22 and a nib holder 26 (e. g. a sleeve surrounding the nib) which may at least partly surround the nib 24 and firmly maintain the latter inside the nib holder 26 ( figures 1D-E ).
  • the nib 24 is fixed inside the nib holder 26 and the latter is fixed to an inner tube 28 (containing the ink tank e.g. through tight engagement or insertion of the second opposed end of the nib 24 into an opened first end of the inner tube 28.
  • the inner tube 28 extends rearwardly and is configured to move in accordance with the mechanism 20 between a position that is proximate the rear end of the barrel 12, in the first forward extended position of figure 1D , and a position beyond the rear end of the barrel 12 in the second rearward retracted position of figure 1E .
  • the filler cap 18 may be tightly mounted inside a second opposed end of the inner tube 28, e.g. by press-fit, so as to ensure air tight and prevent ink from evaporating.
  • the clip can be used as a filler cap: thus, instead of having a filler cap and a clip, one piece may serve for both elements.
  • the writing instrument 10 may further comprise a biasing member 30 (e.g. a spring) that is longitudinally disposed in the instrument and has two opposite ends along its longitudinal dimension: one end, 30a, may rest against at least one fixed stop 32 that is arranged on an inner surface of the barrel 12 ( figs. 1D-E ), e.g. under the form of a peripheral inner ridge, and the opposite end 30b of biasing member 30 may press against a rear part of the inner tube 28, here on an outside shoulder 28a thereof.
  • a biasing member 30 e.g. a spring
  • biasing member 30 is positioned between a fixed part 32 of the barrel and the inner tube 28 so as to exert permanent rearward pulling forces on the latter (in rearward direction R) which tend to pull rearwardly the inner tube 28, and therefore the writing tip extension-retraction system 20 toward the second retracted position of figure 1E .
  • the writing instrument 10 may further comprise a locking system 34 that is movable between two positions:
  • the locking system 34 may comprise both a first part which may be part of a trigger member 36 and configured to be engaged with a first portion of the writing tip extension-retraction system 20 and a second part which may be a fixed inner part 38 of the writing instrument configured to be engaged with a second portion of the writing tip extension-retraction system 20.
  • the trigger member 36 may have an head 36a which corresponds to the first part of the locking system 34 and a tail 36b.
  • the trigger member may have an overall shape of an ax or a hammer.
  • the head 36a is configured to pivot about a pin axis a1 that is perpendicular to the longitudinal axis X of the barrel in the section planes of the figures.
  • the remaining part (body) of the trigger member including the tail 36b may be fixed in embodiments whereas it may be movable, e.g. pivoting, in other exemplary embodiments.
  • the head 36a could pivot differently relative to the body of the trigger member.
  • the pin could be a separate component as a metallic pin that is assembled with the trigger member 36.
  • the head 36a may have a hooked shape at one end so as to engage with a first portion of system 20.
  • the writing tip extension-retraction system 20 may further comprise a member 40, called shock absorber, that is fixed, e.g. through snap-fit, to the first end of the inner tube 28 where the nib 24 is engaged.
  • the shock absorber 40 has an overall shape of a ring or an annular component surrounding the inner tube first end with a longitudinally (here downwardly on figs. 1B-C when the writing instrument is in a writing position) extended tab 40a provided with an externally-oriented edge, groove or the like on which the hook shape of the trigger head 36a may engage in the locked position of figures 1A-D .
  • the longitudinally extended tab 40a may extend beyond the inner tube first end so as to be able to elastically deform in a transverse or radial direction relative to the longitudinal axis X (e.g. inwardly).
  • the shock absorber 40 may further include a diametrically opposed beam member 40b which projects longitudinally (here downwardly) farther from tab 40a so as to be able to engage with the above-mentioned fixed inner part 38 of the writing instrument, in particular with an undercut 38a thereof, thereby forming a separate second locking zone.
  • the inner part 38 may define a sealing chamber together with other internal parts of the writing instrument to prevent the ink evaporation.
  • the beam member 40b which also possesses a radially-oriented elastic capacity of deformation may be equipped with a permanend magnet 42 fixed on its length, in examples on the outside of the beam member.
  • two different locking zones are provided inside the writing instrument of figures 1A-E for locking the writing tip extension-retraction system 20 in its first forward extended locked position of figures 1A-D . These two distinct zones compensate for the biasing forces exerted by the biasing member 30 on the system 20 in the rearward direction R.
  • the writing tip extension-retraction system 20 may further comprise a movable unlocking member that is configured to be moved in the axial rearward direction (R) when the writing instrument is moved from a writing position as shown in figures 1A-C to a rest position as an horizontal position as shown in figures 1D-E that is parallel to the floor or ground or to a lying surface (e.g. table etc.).
  • a movable unlocking member that is configured to be moved in the axial rearward direction (R) when the writing instrument is moved from a writing position as shown in figures 1A-C to a rest position as an horizontal position as shown in figures 1D-E that is parallel to the floor or ground or to a lying surface (e.g. table etc.).
  • the movable unlocking member takes the form of a metallic member 44 such as a sphere or a ball which is in a material that is magnetizable, i.e. it can magnetically interact under the influence of a magnetic field, e.g. it can be magnetically attracted by a permanent magnet such as magnet 42.
  • the movable unlocking member may take the form of a magnetic member.
  • the metallic member may take another form.
  • the writing instrument may further comprise a lateral housing 46 that is laterally fixed to the barrel 12 outside thereof as shown in figures 1D-E , here in an axial position that substantially corresponds to the location in the writing instrument of the trigger member 36 and the fixed inner part 38 where the beam member 40b engages in the locked position.
  • the housing 46 has an overall elongate shape and is hollow so as to accommodate the movable unlocking member 44 therein and allow the latter to slide axially within the housing, depending on the inclination of the writing instrument as shown in figures 1D and 1E .
  • the housing 46 may be mounted in the barrel by snap-fit, press-fit or by using glue.
  • the housing 46 may be further configured internally at its forward most end with an inner tapering portion that is tapered forwardly and flares out rearwardly.
  • the tapered portion may take the shape of internal inclined ribs 48 ( figs. 1C-E ).
  • Such an inner configuration makes it possible for the metallic movable unlocking member 44 to be aided in sliding rearwardly inside the housing when the writing instrument is placed in the horizontal position of figures 1D-E .
  • the writing tip extension-retraction system 20 is locked through two distinct zones inside the barrel as explained above and the metallic movable unlocking member 44 is attracted downwardly by gravity, thereby reaching the position located at the forward most end of housing 46 ( fig. 1C ).
  • the metallic movable unlocking member 44 e.g. sphere
  • the metallic movable unlocking member 44 is caused to move rearwardly along direction R thanks to the tapered inner configuration of housing 46.
  • the movable unlocking member 44 passes near the magnet 42, the magnetic field generated by the latter attracts member 44.
  • the further rearward movement of member 44 drives the magnet rearwardly due to the magnetic attraction, which therefore pulls the beam member 40b rearwardly and cause the latter to mechanically disengage from the undercut 38a.
  • the second locking zone is unlocked.
  • the first locking zone formed by the trigger member 36 engaged with the first portion 40a of the writing tip extension-retraction system 20 remains the only locking zone for system 20 and cannot withstand on its own the biasing forces exerted by biasing member 30. Therefore, the first locking zone is caused to be unlocked (released) under the action of the biasing member 30, thereby causing the locking system to move from the locked position to the unlocked position.
  • the writing tip extension-retraction system 20 is thus automatically released without any specific action from a user (except the change in position of the writing instrument from a wrting position to a rest position, i.e. an horizontal position or even to a position where the writing tip is facing upwardly and the clip 16 downwardly) and can slide rearwardly inside the barrel under the action of biasing member to occupy the second retracted unlocked position of figure 1E .
  • FIG. 2A-2E A second exemplary embodiment of a writing instrument 110 is illustrated in figures 2A-2E .
  • the trigger member is pivotally mounted and engaged through its head 136a with the first portion 140a of the shock absorber 140.

  • the first part here trigger member head 136a
  • the first part is kept engaged with the writing tip extension retraction system 120 in the locked position as long as the second movable part 136b is in the first forward position.
  • the movement of a movable unlocking member caused by the writing instrument change in position will cause the second movable part 136b to move rearwardly (R) from the first forward position to the at least one second rearward position, which will unlock the writing tip extension retraction system 120.

  • the actuator 152a may further comprise a laterally-extending portion 152a1 that bears a permanent magnet 152a2.
  • the assembly 150 comprises the first and second biasing members 154 and 156 (here helicoidal springs) which are disposed on either side of the trigger member tail 136b so that the latter is subject to biasing forces exerted by both biasing members.
  • the biasing member 156 is fixed against a stop member 160 disposed in the alignment of actuator 152a, rod 152b, and piston 158. All these components may be mounted on a supporting member 162, e.g. a longitudinal curved plate, that may be fixed to the outside of the barrel 112.
  • the actuation mechanism 152 may further comprise an engagement body 158, e.g. a piston, which is laterally provided with an engagement member 158a, here inwardly radially oriented toward the barrel, that is configured to engage with a portion 140b of the shock absorber 140, diametrically opposed to the first portion 140a that is engaged with the trigger member head 136a.

  • the housing 164 of figure 2B has been omitted in figures 2C and 2D to show the movable unlocking member 166 that is accommodated within the housing.
  • the housing 164 may have an inner cross section that tapers rearwardly so as to cause the member 166 to slide or roll on the tapered cross section rearwardly.
  • biasing member 156 which is kept on pressing against the other side of trigger tail 136b, causes the latter to move rearwardly (arrow R in figure 2D ) as it does no longer withstand biasing forces from biasing member 154.
  • the rearward motion causes both the piston 158 to push rearwardly on the shock absorber 140 through engagement member 158a and pivoting of the trigger member 136, thereby disengaging the head 136a from the shock absorber 140 at the locking zone 140a-136a. Therefore the mere change in position of the writing instrument as described above makes it possible to automatically unlock the writing tip extension-retraction system 120 and cause the latter to move to a second retracted rearward position wherein the writing tip is retracted inside the barrel ( figure 2D ).
