Definitions

  • the invention relates to a pen of the type stated in the preamble to claim 1. Moreover the invention relates to a method for removing a pen point according to the preamble to claim 11.
  • a type of pen which occurs frequently on the market has a pen body with an ink stick which is removably arranged therein and which at its one end has a pen point and is insertable and extractable through the open end of the pen body.
  • An ink cartridge with a pen point is referred to as ink stick.
  • Access is gained to the ink stick by removing a nose cone which is screwably arranged on the front part of the pen body and which, when being unscrewed, leaves such a long part of the cartridge behind that the user can remove the cartridge by hand from the pen body when, for instance, exchanging the cartridge.
  • the nose cone has a plurality of drawbacks. It must be unscrewed, which makes the exchange of the ink cartridge difficult.
  • the nose cone is a loose part which can easily be lost when exchanging the ink cartridge. Moreover the nose cone makes the manufacture of the pen more expensive.
  • US-4,952,088 shows how a clip arranged on the cap of the pen can be used for form-fit engagement with a specially adapted nose cone, the clip/cap serving as a lever to unscrew the nose cone from the pen body.
  • a problem of the clip according to US-4,952,088 is that the pen point must be specially designed or alternatively must be combined with a nose cone. Moreover. the possibilities of designing the pen are limited by the construction of the clip.
  • EP-0 657 301 A1 shows how a pen point can be extracted from a pen body with the aid of an engaging means arranged on the cap.
  • the engaging means is designed for form-fit engagement with a specially adapted groove in an adaptor sleeve mounted around the pen point.
  • sensors can be arranged in the pen for determining its position, for instance acceleration sensors, as disclosed in US-A-5,434,371 and US-A-6,130,666 , optical sensors, as described in US-A-5,294,792 , US-A-5,852,434 and WO 00/73983 , pressure sensors, as described in US-A-6,104,388 , or mechanical sensors, as described in US-A-5,294,792 and US-A-6,130,666 .
  • acceleration sensors as disclosed in US-A-5,434,371 and US-A-6,130,666
  • optical sensors as described in US-A-5,294,792 , US-A-5,852,434 and WO 00/73983
  • pressure sensors as described in US-A-6,104,388
  • mechanical sensors as described in US-A-5,294,792 and US-A-6,130,666 .
  • the pen body of such digital pens is frequently designed to prevent access to the interior of the pen and the sensitive components therein.
  • the ink stick is therefore inserted into a duct extending into the pen body from its writing end.
  • the present invention relates to a pen of the type described by way of introduction, which solves the above problems, the pen having obtained the features as defined in the characterising clause of claim 1.
  • the present invention further relates to a method for removing a pen point of the type described above, the method having obtained the features as defined in the characterising clause of claim 11.
  • a pen comprising a pen body 1, an ink cartridge arranged in the pen body and having a pen point 3 and a part, such as a clip 4, which is removably arranged on the pen body 1.
  • the ink cartridge 2 and the pen point 3 may form an ink stick which is exchangeable in its entirety.
  • the pen point 3 can be inserted into the ink cartridge 2 and define a distinguishable part, filling of the ink cartridge 2 being allowed after removal of the pen point 3.
  • the pen point 3 or the ink stick in its entirety can be releasably arranged in the pen body 1 in various ways.
  • ⁇ it is possible to use some kind of fit between complementary elements which may be arranged projecting from the inner wall of the pen body 1 and/or from the pen point/ink stick, and which may cooperate to cause locking or anchoring of the pen point or ink stick, which anchoring can be released under the action of a pulling force exerted on the pen point 3.
  • Such elements may comprise, for instance, flaps, beads etc.
  • a common feature of the following exemplifying embodiments is that they allow squeezing engagement with the pen point, so that the pen point can be extracted from the pen body, for instance for exchanging the ink stick or for filling the ink cartridge.
  • the application of the pulling force can, via the squeezing engagement, be executed independently of the nature of the pen point. If the pen point has, for instance, an essentially smooth peripheral surface, the squeezing engagement may result in a frictional force which is sufficient to allow application of the pulling force. If the pen point instead has a profiled peripheral surface, the component or components applying squeezing forces may engage arbitrary protrusions, grooves, flaps etc. on the peripheral surface.
  • the clip can be provided with a hole in the form of a through hole.
  • the clip and a protective cap respectively, can be provided with a hole in the form of a blind hole.
  • blind hole is meant a non-through hole.
  • the shown holes in the form of through holes and blind holes may have a constant cross-section in depth. Alternatively, this cross-section may vary (not shown) over the depth of the hole. Thus, the hole can be tapering or widening in depth.
  • the openings of a through hole may also be of different configurations, for instance different sizes or shapes.
  • the squeezing engagement can be performed by interaction between two parts, such as the cap 11 and the clip 4 in Fig. 8 .
  • the means arranged on the movable part 4 is a hole 5
  • this is formed so that it may be caused, by squeezing action, to engage the pen point 3 for extraction thereof.
  • the hole 5 is dimensioned, so that by exerting a force, for instance a frictional force, it may temporarily hold the pen point 3 to allow removal thereof from the pen body.
  • the hole may have different shapes.
  • a simple embodiment is shown in Fig. 3 , where the hole is essentially circular.
  • the hole is elongate and has wedge-shaped end portions.
  • the hole is formed as a triangle
  • the hole has the form of a "keyhole".
  • a hole 5 as described above can be used to remove the pen point 3, and thus optionally the entire ink stick, from the pen body.
  • the pen point 3 is caused to engage in the hole 5 by inclination/angling of these two relative to each other.
  • step B the pen point 3 is placed in the hole.
  • step C the pen body is angled so that the pen point 3 is fastened in the hole 5, and in step D the pen point/ink stick is extracted.
  • the actions that are taken in step C are modifiable according to the appearance of function of the hole.
  • the clip 4 may be formed as a separate elongate holding part 7 ( Fig. 2 ), which at one end is attached to the pen body or a protective cap and which at its other end possibly has a bend 6 or bead which acts to better hold the pen in place when carried, for instance, in a user's pocket.
  • the elongate holding part 7 of the clip may be elongate, for instance rectangular, in cross-section, so that a flat side is formed, as is evident from Figs 3-5 .
  • the clip has a fixing flange 8, which makes an angle with the elongate holding part 7 of the clip.
  • the angle may be right, but other, larger or smaller, angles are feasible.
  • the fixing flange 8 can be releasably anchored to the pen body 1 at the rear end thereof, for instance by means of a screw, a locking pin, a snap connection, via a press fit or some other fixing means having an equivalent function.
  • the fixing flange 8 may correspondingly be releasably anchored in a groove extending transversely of the longitudinal direction of the pen, which groove may be formed in the pen body 1 or the protective cap 11.
  • the clip in Fig. 2A has a hole 5 in the fixing flange 8, in the form of a through hole or a blind hole for the above engagement with the pen point 3.
  • the hole 5 may be formed in the holding part 7.
  • a hole 5 in the form of a blind hole in the clip, so formed that the pen point 3 can be caused to engage the boundary surfaces of the hole.
  • the hole may have a cross-section varying in depth.
  • a pen according to the invention is shown, in which the part 4, which is removably arranged on the pen body 1, is a protective cap 11 with a clip 4.
  • This clip may, like in the embodiments described with reference to Figs 1-4 , have a hole 5 on its flat side in the form of one or more through holes or blind holes.
  • Such a clip may be formed in one piece with the protective cap 11, or as a separate part.
  • FIG. 7 An alternative is shown in Fig. 7 , viz. a cap 11 with an engaging hole 5 in its one, normally closed end.
  • the hole 5 can either be a blind hole or a through hole, and that the bole 5 can be arranged in an arbitrary position in the cap 11.
  • Fig. 8 which shows one end of a cap with a clip 4, seen from the open end of the cap, there may be formed according to a further alternative, on the underside of the clip 4 at its distal end, a projection with a hole 5 for engaging the pen point projecting from the pen body.
  • the projection can be formed on the pen body to define said hole 5.
  • the pen point can be inserted into the hole 5, after which the cap 11 and the pen body 1 are angled to each other to provide the engagement similarly to the above embodiments involving a through hole or a blind hole.
