Definitions

  • a writing instrument of the above kind avoids the use of a separable cap that can be lost, while providing a function of protection of the writing tip.
  • the document FR 2,103,492 discloses a writing instrument which has a protective sleeve with a substantially conical front end and whose retracted position which permits writing is maintained by the introduction of a locking protrusion in a cell or a stop groove formed on the outer face of the tubular body.
  • This type of protective sleeve has an elastic clip provided with a ridged zone to allow the user to push back the protective sleeve and thus engage the retracted position for writing, by engagement of the locking member.
  • the elasticity of the clip makes it possible to lift and then push the protective sleeve forward in order to obtain a return to the protection position.
  • the object of the present invention is to propose a retractable protective sleeve writing instrument whose mechanism is reliable and which remains simple in design.
  • the elastic return element minimises the locking of the respective positions (retracted position and protection position) without any other action on the part of the user. It is also interesting to note that it is the protective sleeve that forms the actuator, the rotating cam rotating towards one or the other of the locking positions in response to the rearward movement of the actuator. protective sleeve. It is thus understood that the body may be free of roughness (without staple or ratchet protruding on one side) and the actuating portion formed by the protective sleeve can then be particularly robust.
  • the protective sleeve may have a protective portion with at least one recess on its outer surface.
  • the grip between two fingers of the protective sleeve is then facilitated.
  • the user can move the protective sleeve by clamping between the index finger and middle finger, while the body is held firmly between the thumb and the index finger.
  • the index and / or the middle finger enters the recess or recesses for a better grip of the protective sleeve.
  • This type of structure allows the user to effectively push the protective sleeve back in the manner of a push button to actuate the transition from one position to another of the protective sleeve.
  • the rotary cam extends annularly around an intermediate portion of the writing member (the intermediate portion being axially distant from the front and rear ends of the writing member).
  • the elastic return member may be located rearwardly with respect to the rotary cam by extending at least partially around and / or along the writing member.
  • the protective sleeve comprises a guide portion sliding along the body along an axis parallel to the longitudinal axis of the hollow body (and preferably coincides with this longitudinal axis) and a protective portion which extends the guide portion. and has a through-hole for the tip, the protective sleeve including an annular shoulder which defines a rear face of the shield portion, the protective sleeve being freely pushable back to a support of the annular shoulder against the front end of the body.
  • This arrangement makes it possible to control the end of travel of the pusher formed by the protective sleeve, the force exerted on the elastic return element (typically a compressive force when it is a spring) always being the same.
  • This structure is particularly robust and the user's grip on the protective sleeve can be facilitated by the presence of at least one cavity or recess for the fingers.
  • the rotary cam can rotate by camming when the protective sleeve reaches the end of stroke (position bearing against the front end of the body), while the reaction force of the elastic return element is at maximum. It is understood that the passage in the next position of the protective sleeve is fast after the push back, the locking member is already vis-à-vis the corresponding stop. The advance of the rotary cam into its engagement position is simply triggered by the return to position of the elastic return element.
  • a plastic washer may optionally be interposed between the rotary cam and the elastic return element. Such a washer can minimize friction during rotation of the rotating cam.
  • the front end of the body has an opening, the body defining an internal volume, and the protective sleeve is mounted in the body through said opening, the guide portion of the protective sleeve being inserted into the internal volume of the body and extending longitudinally along the longitudinal axis of the body.
  • the support face is formed on a piston, the writing member being displaceable with the piston in translation towards the rear in the hollow body, an additional spring being arranged on the side of the rear end of the hollow body. bearing on a rear face of the piston opposite the support face, for generating a repulsive force which urges the writing member forward and is adapted to damp a writing pressure in the retracted position of the sleeve protective.
  • the passage to the protective position of the sleeve can be done by a front thrust against the front of the writing instrument.
  • the user can in this case, with one hand, press the tip then the sleeve against a rigid support in the same thrust movement (the tip moving backwards with the sleeve), so as to obtain the position protection as soon as the thrust is released.
  • the tip then protrudes to the front of the body under the elastic return effect of the additional spring (the remaining sleeve locked in the retracted position).
  • Obtaining the retracted position can be similar, the tip flush with the front end of the sleeve. It is understood that in this case the two positions of the instrument are each actuated by repoussage (same mode "puncher” than for stamping), in response to the support on a surface initiated by the hand of the user.
  • the piston bears, under the effect of the repulsive force of the additional spring, against an internal abutment of the body for said protective position and for said retracted position of the protective sleeve, thanks to which the writing member has in the protective position and in the retracted position the same relative position with respect to the hollow body.
  • the rotary cam is located in said internal volume and extends annularly about said longitudinal axis by defining an interior space, the writing member being movable in translation along the longitudinal axis in this interior space . It is thus understood that the writing member can move independently of the protective sleeve, for example to dampen the writing pressure. Thus this axial mobility during writing does not have the slightest impact on the locking of the protective sleeve.
  • the writing instrument 1 makes it possible to write by any writing, erasing or highlighting medium, hereinafter referred to as ink by means of a writing tip 2.
  • the writing instrument 1 comprises a hollow body 2 preferably tubular to form a drum.
  • This hollow body 2 extends longitudinally (along a longitudinal axis X) between a rear end 2a and a front end 2b which has an opening 2c which is here axial.
  • the writing instrument 1 is devoid of a cap and has a protective sleeve 3 movable at the front of the hollow body 2.
  • the writing member 4 housed inside the hollow body 2 may have a generally cylindrical shape of way known per se, forming for example a cartridge (possibly replaceable by removing the rear end 2a of the body 2). It is understood that the longitudinal axis X forms a central axis which passes through the hollow body 2, the protective sleeve 3 and the writing member 4.
  • the writing member 4 is mounted in the internal volume V of the hollow body 2, resting at a rear end 4a on a support face F1 defined at the front of a piston P.
  • the front end 4b of the writing member 4 has a tip 4c located outside the internal volume V and projecting in front of the hollow body 2 as is visible on the figure 1 .
  • the support face F1 of the piston P has a base which extends transversely to the longitudinal axis of the hollow body 2 and teeth and / or at least one wall which extend from the base to allow centering of the body writing 4 in the internal volume V of the body 1.
  • the writing member 4 Due to the engagement of the rear end 4a of the writing member 4 on the piston P, the writing member 4 is movable with the piston P in translation respectively rearwardly and forwards in the hollow body 2.
  • a spring R is arranged on the side of the rear end 2a of the body 2 and bears on the piston P on the side of the rear face F2 opposite to the support face F1.
  • This spring R which is axially constrained is supported on a plug 40 which closes the rear end 2a of the body 2 in a manner known per se.
  • This spring R here makes it possible to generate a repulsive force which urges the writing member 4 forward and is adapted to damp a writing pressure in the retracted position of the protective sleeve 3 (this retracted position being clearly visible on the figures 1 and 4A ).
  • the protective sleeve 3 comprises a guide portion 5, here of generally tubular shape, which slides along the body 2, in the internal volume V.
  • the guide portion 5 is extended forwards by a protective portion 6 which has a through hole 6a for the tip 4c. This passage hole 6a is axial.
  • the protective sleeve 3 forms a tapered front end of the writing instrument 1, the shielding portion 6 in particular being conical in shape or the like.
  • the guide portion 5 and the protective portion 6 extend around the same central axis, here coincides with the longitudinal axis X of the hollow body.
  • the guide portion 5 preferably has a generally cylindrical shape.
  • the longitudinal axis X is a central axis for the protective sleeve 3 and for the front part of the hollow body 2.
  • the protective sleeve 3 is mounted in the hollow body 2 through the opening 2c formed at the front end 2b, so that the guiding portion 5 of the protective sleeve 3 is inserted into the internal volume V 2.
  • the writing member 4 completely through the protective sleeve 3, the writing instrument 1 then being in a configuration for writing.
  • the protective sleeve 3 is here formed of a single piece of injected plastic material.
  • the guide portion 5 of the protective sleeve 3 may have a length less than the length of the protective portion 6, which here has a generally conical shape. Thus, the quantity of material is minimized for producing the protective sleeve 3.
  • the protective sleeve 3 extends longitudinally along a central axis, which typically coincides with the longitudinal axis X of the hollow body 2 ( figure 1 ).
  • the guide portion 5 slides in an area defined by a first tubular section 7 of the hollow body 2.
  • a second tubular section 8 of the hollow body 2 extends rearwards the first section 7 and has internal ribs 9 so that the section internal of the hollow body 2 narrows at the junction between the first tubular section 7 and the second tubular section 8.
  • the internal section defined by the first tubular section 7 is here constant and devoid of relief, with the exception of a guide member such as a slot 7a which cooperates with an anti-rotation member 5b complementary 5b (male or female) formed on the outer face of the guide portion 5 to prevent rotation of the protective sleeve 3.
  • a guide member such as a slot 7a which cooperates with an anti-rotation member 5b complementary 5b (male or female) formed on the outer face of the guide portion 5 to prevent rotation of the protective sleeve 3.
  • the slot 7a extends longitudinally to the front end 2b of the hollow body 2 and the anti-rotation member 5b is a longitudinal rib which joins the rear end of the protective part 6.
  • the anti-rotation member 5b can be shortened.
  • the guiding portion 5 can be entirely inserted into the internal volume V of the hollow body 2, being here completely covered by the first tubular section 7.
  • this insertion state can be a state intermediate between the two positions (retracted position and protective position) taken by the protective sleeve 3.
  • the guide portion 5 is extended longitudinally rearwards by a rotary cam 10 arranged coaxially with the protective sleeve 3.
  • the rotary cam 10 is attached to the guide portion 5 of the protective sleeve 3 by a connection 11.
  • this connection 11 is made by inserting an annular outer bead 10a of the rotary cam 10 into an annular retention groove 5c formed on the inner face of the guide portion 5.
  • connection 11 allows a small axial clearance between the rotary cam 10 and the protective sleeve 3 and allows the rotary cam 10 to rotate about the longitudinal axis X (unlike the sleeve 3 which has the anti-rotation member 5b).
  • This axial clearance is much lower than the axial displacement of the protective sleeve 3, so that the rotary cam 10 moves backwards in the internal volume V when the protective sleeve 3 is pushed backwards.
  • the example shown shows the coupling of an annular outer bead 10a in an annular groove 5c, it is understood that any other coupling mode can be used to make the connection 11 with an axial clearance, for example by using a or more cells for retaining a complementary projecting member such as a rib.
  • the writing instrument 1 may comprise only three tubular outer parts formed of plastic: the hollow body 2 tubular, the protective sleeve 3 and the plug 40.
  • the number of parts is thus very reasonable to obtain the locking system of the two positions, with the further advantage that the locking system is fully integrated in the internal volume V of the hollow tube 2.
  • the rotary cam 10 comprises at least one locking member, here several locking teeth 12, 13, 14 distributed over the circumference of a tubular body 15.
  • An internal space 10b is defined inside this tubular body 15.
  • L the writing member 4 passes entirely through the tubular body 15 of the rotary cam 10 via this internal space 10b, and can, if appropriate, slide independently of the movement of the assembly formed by the protective sleeve 3 and the rotary cam 10, according to the axial direction defined by the longitudinal axis X.
  • These locking teeth 12, 13, 14 are adapted to engage with a fixed cam defined by the internal ribs 9 of the second section 8.
  • the internal ribs 9 are spaced to form longitudinal cuts 9a, 9b.
  • the second section 8 provided with the fixed cam can for example look like or have a structure identical to a section used to form the barrel of the BIC Velocity® pen (the position of this second section 8 is however very different because in the first and second sections 7, 8 are provided on the side of the front end 2b of the body hollow 2 in the writing instrument 1 according to the invention).
  • the ends at the rear of the respective ribs 9 form a series of first stops B1, B2, B3, B4, B5, B6.

  • the series of first stops B1, B2, B3, B4, B5, B6 is defined by the funds. respective of these short cuts 9a.
  • a series of second stops 20 is defined by the respective bottoms of the main, longer notches 9b, the locking teeth 12, 13, 14 engaging these second stops 20 by sliding forwardly between two adjacent ribs 9.
  • the short cuts 9a and the longer notches 9b open axially towards the rear in the same annular zone of the hollow body 2, as is clearly visible in FIG. figure 6 .
  • first stops B1, B2, B3, B4, B5, B6 are shifted further back in the hollow body 2 with respect to the second stops 20 and that the rotation of the rotary cam 10 makes it possible to alternate between engagement with the first stops B1, B2, B3, B4, B5, B6 and the engagement with the second stops 20.
  • the protective sleeve 3 has at its rear end a toothing 21 adapted to engage with the rotary cam 10, in particular with projecting projections 15a which project radially outwardly from the outer surface of the tubular body 15. These projections 15a are offset axially rearwardly relative to the annular outer bead 10a or similar coupling reliefs between the protective sleeve 3 and the rotary cam 10. These projecting projections 15a have a beveled front face engaging with the toothing 21 of the protective sleeve 3.
  • the number of teeth of the toothing 21 may correspond to the cumulative number of first and second stops B1, B2, B3, B4, B5, B6 and 20.
  • the toothing 2 extends annularly at the rear end of the guide portion 5, the recesses opening towards the rear at the axial opening 5a.
  • toothing 21 By cooperating with projecting projections 15a as illustrated on the figure 7 , toothing 21, can initiate a rotation of a comparable angle and preferably less than or equal to the angular offset between the notches of a pair of notches 9a, 9b adjacent. As shown in figure 6 , the notches of such a pair extend longitudinally on the inner face of the hollow body 2, one of the notches being longer than the other.
  • This disengagement allows the rotary cam 10 to rotate by a predetermined low angle of rotation (first angle), here much lower than 45 ° and for example less than 20 °.
  • This slight rotation results from the complete insertion (closer contact) of projecting projections 15a in the recesses of the toothing 21 of maneuvering as illustrated on the figure 7 (arrow C).
  • the toothing 21 here comprises a series of ramps 16 distributed annularly and which each extend from a sharp edge or similar end edge 17 of the toothing 21 to the bottom of the recesses.
  • the protruding projections 15a slide on these ramps 16 to generate the slight rotation of the rotary cam 10.
  • the crossing of the end edges 17 is allowed thanks to the axial clearance at the connection 11, which allows sufficient relative movement between the guiding portion 5 of the protective sleeve 3 and the rotary cam 10 to allow a continuation of the rotational movement according to the arrow C.
  • the front end E of the locking teeth 12, 13, 14 is sufficiently in front of the adjacent notch to allow the rotational movement to continue at a second angle much less than 45 °.
  • the sum of the first angle and the second angle corresponds to approximately 30 °, the total number of notches 9a, 9b being equal to 12 (the number of recesses in the set of teeth 21 being here equal to 12).
  • each of the projecting projections 15a is aligned with one of the locking teeth 12, 13, 14 and the same beveled shape is used in front of these reliefs formed on the tubular body 15 of the rotary cam 10.
  • the outer surface of this tubular body 15 is generally cylindrical with an external diameter D2 slightly smaller than the internal diameter D1 of the guide portion 5.
  • the locking teeth 12, 13, 14 are formed on the rear end of the rotary cam 10 and protrude radially outwardly similarly to the projecting projections 15.
  • the radial extension e2 of the locking teeth 12, 13, 14 is greater than the radial extension e1 of the projecting projections 15a. With such a radial extension e2, it is permissible to limit the thickness of the hollow body 2 at the level of the fixed cam (minimized thickness at the internal ribs 9) and thus saves material.
  • the number of locking teeth 12, 13, 14 or similar locking members is less than the number of first stops B1, B2, B3, B4, B5, B6 and less than the number of second stops 20.
  • connection 11 the arrangement of the fixed cam formed in the second section 8 and the toothing 21 make it possible to control the movement of the rotary cam 10.

  • the coil spring could be replaced by a resilient plate secured to the piston P or possibly by a series of several springs placed end to end. More generally, any elastic return means can be used with a bearing force, directly or indirectly, against the protective sleeve 3.
  • the protective position of the protective sleeve 3 is obtained instantaneously after the disengagement of the locking teeth 12, 13, 14 with respect to the first stops B1, B2, B3, B4, B5, B6, because of the action of the spring 22 according to the arrow B.

  • the user can either grasp only the protective sleeve 3 and push it backwards, for example by placing his fingers in the recesses 25, 26, or axially pressing the writing instrument 1 (typically up and down) against a rigid surface. In all cases, this action pushes the assembly formed by the protective sleeve 3 and the rotary cam 10 towards the rear.
  • the presence of the additional spring R makes it possible to obtain a rearwards withdrawal of the tip 4c inside the protective part 6 so that a direct contact can be obtained between the rigid surface and an annular front face 6b of this protection part 6, which then allows to push the protective sleeve 3 and the rotary cam 10 backwards.

  • This bearing position is also taken for the retracted position of the protective sleeve 3.
  • the writing member 4 has, in the protection position and in the retracted position, the same relative position with respect to the hollow body 2. it is understood that the locking alternately on the first or the first stops B1, B2, B3, B4, B5, B6 and on the second or second stops 20 makes it possible to control the sliding of the protective sleeve 3 independently of the fact that the writing member 4 has axial mobility.
  • the writing instrument 1 is devoid of the additional spring R. It is understood in this case that the user can then specifically enter the protective part 6 to push back.
  • the writing member 4 is held fixedly in the hollow body 2 by resting on the support face F1 formed here at the front end of the plug 40 ', without sliding.
  • the spring 22 or similar elastic return member operates in a similar manner to the example of the figure 1 .

  • the length of the spring 22 may be greater than the length of the protective portion 6, the thrust force of the spring 22 in the protective position is preferably significantly lower than the thrust force in the retracted position.
  • One of the advantages of the invention lies in the simplicity and ergonomics of the writing instrument, a user can obtain the protection of the tip 4c without actuating a specific actuator.It is also understood that the locking system is here shortly bulky, the general shape of the front part of the writing instrument 1 tubular can remain thin.
  • the design and assembly of the writing instrument 1 remain particularly simple, which makes the manufacture less expensive.
  • the rotary cam 10 can be introduced into the internal volume V of the hollow body 2 by the rear end 2a, while the protective sleeve 3 is inserted through the opening 2c of the front end 2b.
  • the annular outer bead 10a of the rotary cam 10 is engaged in the annular groove 5c of retention to allow to attach this rotary cam 10 to the guide portion 5 of the protective sleeve 3. Due to the plastic deformation of the protective sleeve 3 the annular bead 10a can be inserted through the rear end 2a where the passage section has a diameter slightly smaller than the outer diameter of the annular bead 10a.
