Definitions

  • the present invention relates to the field of writing instruments, and more particularly to their assembly.
  • writing instrument means any instrument that can be used to manually trace a writing on a suitable surface.
  • the writing instruments it is possible to count, for example, pencils, feathers, ballpoint pens or markers, and even adapted pens. All of these writing instruments typically have an elongated shape allowing a front portion of the writing instrument to be grasped between the tips of the thumb and at least one of the index and middle finger, while a back portion is supported in the grip angle between the thumb and index finger to stabilize the writing instrument in the hand.
  • Some of these ergonomic writing instruments comprise a front body and a rear body rotatable relative to the front body relative to a longitudinal axis, for example to actuate an extension and retraction mechanism of a dart. as disclosed for example in the patent application US 2011/318083 A1 .
  • a disadvantage of such writing instruments with a front body and a rear body rotating relative to each other is that of the difficulty of ensuring a reliable mechanical connection between the front body and the rear body, with connecting means for a simple assembly and easily industrializable.
  • a screw connection or for example that disclosed in the international patent application WO 2007/010323 A1 , do not seem suitable.
  • the present invention aims to remedy these disadvantages.
  • the invention aims to provide a writing instrument comprising a front body, and a rear body adapted to rotate, relative to the front body, about a longitudinal axis a front body, which can be assembled in a simple economic manner and reliable.
  • the clipping is a method of assembling two parts by engagement and elastic deformation (in general local deformation, for example of a tongue).
  • elastic deformation in general local deformation, for example of a tongue.
  • the two parts can also cooperate to oppose, or even block, their relative movements in the direction of the extension of the engagement, beyond the latching position.
  • this elastic detent may be radial, that is to say, a snap in which the tubular member expands radially towards its detent position after engagement.
  • This tubular piece may have shoulders opposed to corresponding shoulders of the front and rear bodies to axially retain said tubular piece relative to the front and rear bodies.
  • This configuration simplifies the mechanical assembly of the writing instrument, which can thus be assembled by simple axial engagement of the front and rear bodies, in opposite directions, against the tubular piece.
  • the tubular piece may have a certain radial elasticity to allow snapping, its radial shoulders bearing against those of the front body and the rear body after resilient expansion to retain them axially. This tubular piece can in particular be received in the writing instrument, thus allowing an invisible connection between the front body and the rear body.
  • the tubular piece may be integral in rotation with one of said front and rear bodies and have two abutments in rotation relative to each other of said front and rear bodies. Thus, this piece can be used to limit the relative rotation between the two bodies.
  • this elastic piece may comprise a longitudinal slot.
  • it can also receive, in this longitudinal slot, a rib integral with one of said front or rear body.
  • the longitudinal slot can thus also serve to lock the tubular piece in rotation with respect to one of said front or rear body.
  • the rib can be engaged by force in the longitudinal slot, so as to cause the radial expansion of the tubular piece and the engagement of the tubular piece with internal shoulders in at least one of the front or rear body to ensure the axial connection between the front and rear bodies through the tubular piece.
  • the writing instrument may further comprise a writing tip, and a retraction mechanism and extension of the writing tip, actuated by relative rotation of the front body and the rear body.
  • this retraction and extension mechanism may comprise a cam surface rotatably connected to one of said front body and rear body and an element integral in rotation with the other of said front body and rear body and in contact with each other. with said cam surface, the cam surface or said element in contact with the cam surface being able to move in the writing instrument along said longitudinal axis and being integral with the writing tip at least in translation following the longitudinal axis.
  • the cam surface thus makes it possible to convert the rotational movement between the front and rear bodies into a translation movement of the writing tip along the longitudinal axis.
  • the retraction and extension mechanism may also include an elastic member installed to urge the second member against the cam surface.
  • Some of these ergonomic writing instruments such as the one disclosed in the international patent application WO 01/97653 , a front body with an ergonomic grip segment asymmetrical with respect to a first longitudinal plane, and an asymmetrical rear body with respect to a second longitudinal plane, different from the first longitudinal plane.
  • the gripping segment is thus adapted to grip between the fingertips, while the asymmetry of the rear body makes it possible to better match the shape of the grip angle, that is to say the space between the thumb and the index finger of a hand.
  • the front body may comprise an asymmetrical ergonomic grip segment relative to in a first longitudinal plane, and the rear body being asymmetrical with respect to a second longitudinal plane the rear body and rotatable, relative to the front body, between a position adapted to a grip with a right hand and a position adapted to a taken with a left hand.
  • the shape of the writing instrument can be adapted to ergonomic use alternately with the left hand or with the right hand, so that the ergonomics of this instrument is no longer in conflict with its versatility .
  • the ergonomic gripping segment In order to separate the index finger and the thumb on the ergonomic gripping segment, it can have, on one side of said first longitudinal plane, a rib oriented longitudinally, and radially projecting with respect to a gripping surface of said segment.
  • this rib can be protruding at least 2 mm from the gripping surface of said segment. This rib can facilitate the learning of writing, helping schoolchildren to position correctly fingers on the ergonomic grip segment. In addition, it also provides a more stable grip of the writing instrument.
  • the ergonomic gripping segment may furthermore have a finger-stop flange towards a front end of the front body, for example at a distance of at least 10 mm from this distal end, so as to ensure a sufficient distance fingers in relation to the writing surface, in order to clear the field of view of the user, which is not only advantageous during the learning of writing to schoolchildren, but also makes it more comfortable to other users.
  • this flange can in particular be inclined relative to the longitudinal axis.
  • said ergonomic grip segment may furthermore have a flexible gripping surface, preferably overmolded on the front body.
  • the rear body may comprise, on one side of said second longitudinal plane, a concave surface configured to bear on the base of the index finger.
  • this writing instrument may further comprise a writing tip, and a mechanism for retraction and extension of the writing tip, actuated by relative rotation of the front body and the rear body, and configured so that the writing tip is retracted into the front body when the rear body and the front body are in an intermediate position between the position adapted to the grip with the right hand and the position adapted to the grip with the left hand, and protruding beyond a front end of the front body when the rear body and the front body are in the position adapted to grip with the right hand or in the position adapted to the pr ise with the left hand.
  • this cam surface may be symmetrical.
  • This writing instrument 1 which in the illustrated embodiment takes more specifically the form of a ballpoint pen, comprises a front body 2 and a rear body 3 which can rotate, relative to each other, around a longitudinal axis X.
  • the front body 2 comprises two parts: an ergonomic grip segment 4 and a tip 5 forming a distal end of the front body 2.
  • the segment 4 is asymmetrical with respect to a longitudinal plane A, since it has, in particular, on one side only of this longitudinal plane A, a rib 6 radially projecting. When using the instrument 1, this rib 6 functions as a key to facilitate the decision by separating the thumb of the index finger.
  • the segment 4 also has a flange 7 radially projecting, opposing the fingers in the direction of the front end of the front body 2, and also facilitating in this way the catch of the index fingers and major and thumb around the segment 4. In the illustrated embodiment, this flange 7 is inclined in the axial direction for a better setting comfort of the segment 4.
  • the segment 4 also has a grip surface 8 overmoulded, a softer material than the rest of the segment 4.
  • This surface grip 8 slightly concave, may also have a texture in relief or protruding for a more certain grip.
  • the tip 5 has a conical outer surface and a complementary thread of an internal thread inside the segment 4 for attachment to the front end of the segment 4.
  • the rear body 3 is asymmetrical with respect to a longitudinal plane B, since it has in particular, on one side of this longitudinal plane B, a concave bearing surface 9 to facilitate the support of the rear body on the base of the index finger in the grip angle of the user's hand.
  • the index finger will be on one side or the other of the rib 6.
  • the rear body 3 can rotate relative to the front body 2, about the longitudinal axis X, between the position illustrated on the figure 2 , which is adapted for use with the right hand with the concave surface 9 to the right of the rib 6, and the position illustrated on the figure 3 , which is adapted for use with the left hand with the concave surface 9 to the left of the rib 6.
  • the instrument 1 can also adopt the intermediate position illustrated on the figure 1 , between the positions of Figures 2 and 3 in which the longitudinal plane A of the front body 2 coincides with the longitudinal plane B of the rear body 3.
  • the instrument 1 comprises a retractable writing tip 10, and a retraction mechanism and extension of this writing tip 10 which is actuable by relative rotation of the front body and rear body 2,3, and configured so that the writing tip 10 is retracted into the front body 2 when the front and rear bodies 2, 3 are in the intermediate position shown on the figure 1 , and protruding beyond the front end of the front body 2 when the front and rear bodies 2,3 are in the positions illustrated on the Figures 2 and 3 .
  • the angle of rotation ⁇ of the rear body 3 with respect to the front body 2, between the intermediate position illustrated on the figure 1 and each of the positions illustrated on the Figures 2 and 3 can be, for example, 120 °.
  • the figure 4 illustrates an exploded perspective of the instrument 1, to appreciate its internal components.
  • a resilient element 11 in the form of a helical spring, a standard ballpoint refill 12, a slide 13 and a tubular piece 14.
  • the refill 12 comprises the writing tip 10 and an ink tank 15 and is received within the slider 13, which is open forwards and at least partially closed towards the rear.
  • FIG 5 which is a cross section of the instrument 1 according to the VV plane of the figure 1 , ribs 16, 17 on the inner surface of the front body 2 cooperate with grooves 18, 19 on the outer surface of the slider 13, so as to make the slider 13 integral with the front body 2 rotated about the longitudinal axis X while permitting axial displacement of the slide 13 along the longitudinal axis X.
  • the slider 13 also has a finger 20 on its outer surface. As we can see on the figure 6 this finger 20 is in contact with a cam surface 21 formed in the inner surface of the rear body 3 and constitutes with it a mechanism for extending and retracting the writing tip 10.
  • the cam surface 21 has a contour helical adapted to push the finger 20 forward when the rear body 3 rotates in one or the other direction from the intermediate position illustrated on the figure 1 .
  • the finger 20 is connected to the writing tip 10 through the slider 13 and the refill 12
  • the rotation of the rear body 3 in one or the other direction about the longitudinal axis X with respect to the front body 2 will actuate the movement of the writing tip 10 between its retracted position, illustrated in FIG. figure 6 , and its writing position, illustrated on the figure 7 .
  • the writing tip 10 is received in the front body 2, and more specifically, in the illustrated embodiment, in the mouthpiece 5. In the writing position, illustrated in FIG. figure 7 the writing tip 10 protrudes beyond the front end of the front body 2.
  • the cam surface 21 is more clearly visible on the Figures 8 and 9 , illustrating, respectively, a partial cutaway of the rear body 3, and a partial longitudinal section along an IX-IX plane perpendicular to the plane B.
  • the cam surface 21 is symmetrical with respect to the longitudinal plane B , so as to actuate the same extension movement of the writing tip 10 when the rear body 3 is rotated in either direction from the intermediate position illustrated on the figures 3 and 6 .
  • this cam surface has, on each side, a notch 22 at the end of stroke intended to hook the finger 20 and thus block the writing tip 10 in its writing position.
  • each notch 22 is such that it offers only a slight resistance to the rotation of the rear body 3 when the user rotates it, relative to the front body 2, from this position to its intermediate position to retract the writing tip 10 in the front body 2.
  • the rear body 3 also comprises, on its inner surface, radial shoulders 24 and a longitudinal rib 25 intended to cooperate with the tubular part 14.
  • the segment 4 also has, on its rear end, lips 26, 27 intended to cooperate with the tubular piece 14, as well as a rotation stop 28.
  • This tubular piece 14 is illustrated in greater detail on the Figures 12 to 14 . In these figures, one can appreciate how it has a longitudinal slot 29. On the one hand, thanks to this longitudinal slot, the tubular member 14 is more easily elastically deformable in a radial plane.
  • this slot 29 is adapted to receive the rib 25 of the rear body 3, so as to cooperate with it to make the tubular part 14 integral with the rear body in rotation, as shown in particular on the figure 5 .
  • the width of the slot 29 when the tubular piece 14 is free of stresses is however less than that of the rib 25, so that when the rib 25 is inserted into the slot 29, it causes the radial expansion of the piece.
  • tubular 14 On the Figures 12 to 14 it can also be appreciated how the tubular member 14 has radial shoulders 30 on its outer surface.
  • the rear edge 31 of the tubular part 14 also forms a radial shoulder against which the lips 26, 27 of the segment 4 rest to thus axially retain the front body 2 by resilient snapping, without, however, preventing its rotation relative to the tubular part 14. and rear body 3.
  • the tubular piece 14 also has axial protuberances on its front edge 32, forming stops 33 in rotation, which abut against the corresponding stop 28 of the front body 2 to limit the relative rotation of the rear body 3 relative to the front body 2.

  • the slider 13 is introduced into the segment 4, and the tubular piece 14 is threaded, thanks to its radial elasticity, onto the rear end of the segment 4 until that its rear edge 31 can bear on the front faces of the lips 26. Then, the rear end of the segment 4, with the tubular piece 14 and the slider 13, is introduced into the rear body 3, with the slot 29 of the tubular part 14 aligned with the rib 25 of the rear body 3, and the grooves 18, 19 of the slide 13 aligned with the ribs 16, 17 corresponding to the inner surface of the segment 4.
  • the rear end of the segment 4 and the tubular piece 14 can penetrate into the front end of the rear body until that the commitment to force of the rib 25 in the slot 29 causes the radial expansion of the tubular part 14, so that its radial shoulders 30 bear on the radial shoulders 24 of the rear body 3 and axially locking the segment 4 relative to the rear body 2
