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.

Abstract
Description
- 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 toUS-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. Some problems of the engaging means according toEP-0 657 301 A1 are its restriction of the possibilities of designing the pen, the risk of it getting stuck, for instance, in the user's clothes, and the necessary cooperation with a specially adapted adaptor sleeve. - Besides conventional writing materials, also so-called digital pens have recently been developed, which contain sensors and electronics for digital recording of what is being written by means of the pen on a base. Different types of sensors can be arranged in the pen for determining its position, for instance acceleration sensors, as disclosed in
US-A-5,434,371 andUS-A-6,130,666 , optical sensors, as described inUS-A-5,294,792 ,US-A-5,852,434 andWO 00/73983 US-A-6,104,388 , or mechanical sensors, as described inUS-A-5,294,792 andUS-A-6,130,666 . For reasons of security, 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. Like in ordinary pens of this type, it is difficult for the user to exchange the ink stick, whether the pen has a nose cone or not. - Thus 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. - Embodiments of the invention according to its different aspects are evident from the dependent claims and the following description, reference being made to accompanying schematic drawings.
-
Fig. 1 is a longitudinal sectional view of an embodiment of a pen according to the invention. -
Figs 2A-2C are side views of releasable clips according to different embodiments of the invention. -
Fig. 3 is a perspective view of a clip with a hole in its flat side. -
Figs 4A-C are plan views of clips with holes according to three different embodiments. -
Figs 5A-5B are a sequence of perspective views to illustrate an embodiment of a method for removing a pen point according to the invention. -
Fig. 6 is side view of one more embodiment of a pen according to the invention with inner parts indicated by dashed lines. -
Fig. 7 is a side view of a removable cap according to an embodiment of the invention. -
Fig. 8 is an end view of a removable cap provided with a clip having a hole for engagement with a pen point. - With reference to
Fig. 1 , an embodiment of a pen according to the invention is shown, comprising apen body 1, an ink cartridge arranged in the pen body and having apen point 3 and a part, such as aclip 4, which is removably arranged on thepen body 1. - The
ink cartridge 2 and thepen point 3 may form an ink stick which is exchangeable in its entirety. Alternatively, thepen point 3 can be inserted into theink cartridge 2 and define a distinguishable part, filling of theink cartridge 2 being allowed after removal of thepen point 3. - In the embodiment according to
Fig. 1 , thepen point 3 or the ink stick in its entirety can be releasably arranged in thepen body 1 in various ways. - According to one embodiment, 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 thepen point 3. Such elements may comprise, for instance, flaps, beads etc. Alternatively, it is possible to form the inside of the pen body so that the pen point or ink stick is kept in place by press fit, which can also be neutralised under the action of a pulling force. - Various examples of means for adequate exertion of the above-mentioned pulling force follow below. In all cases, these means are included in a part which is removably arranged on the
pen body 1. 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 accompanying drawings illustrate several examples of how the squeezing engagement can be performed.
- According to
Figs 2A and3-5 , the clip can be provided with a hole in the form of a through hole. According toFigs 2C and7 , the clip and a protective cap, respectively, can be provided with a hole in the form of a blind hole. By "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.
- According to
Fig 8 , the squeezing engagement can be performed by interaction between two parts, such as thecap 11 and theclip 4 inFig. 8 . - According to the embodiments where the means arranged on the
movable part 4 is ahole 5, this is formed so that it may be caused, by squeezing action, to engage thepen point 3 for extraction thereof. Thehole 5 is dimensioned, so that by exerting a force, for instance a frictional force, it may temporarily hold thepen point 3 to allow removal thereof from the pen body. The hole may have different shapes. A simple embodiment is shown inFig. 3 , where the hole is essentially circular. According to an alternative embodiment, shown inFig. 4A , the hole is elongate and has wedge-shaped end portions. In the embodiment according toFig. 4B , the hole is formed as a triangle, and in the embodiment according toFig. 4C , the hole has the form of a "keyhole". - With reference to
Fig. 5 , it is shown how ahole 5 as described above can be used to remove thepen point 3, and thus optionally the entire ink stick, from the pen body. Thepen point 3 is caused to engage in thehole 5 by inclination/angling of these two relative to each other. In step B, thepen point 3 is placed in the hole. In step C, the pen body is angled so that thepen point 3 is fastened in thehole 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 abend 6 or bead which acts to better hold the pen in place when carried, for instance, in a user's pocket. The elongate holdingpart 7 of the clip may be elongate, for instance rectangular, in cross-section, so that a flat side is formed, as is evident fromFigs 3-5 . - According to an embodiment, which is shown in
Fig. 2A , the clip has a fixingflange 8, which makes an angle with the elongate holdingpart 7 of the clip. The angle may be right, but other, larger or smaller, angles are feasible. The fixingflange 8 can be releasably anchored to thepen 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. Alternatively, the fixingflange 8 may correspondingly be releasably anchored in a groove extending transversely of the longitudinal direction of the pen, which groove may be formed in thepen body 1 or theprotective cap 11. The clip inFig. 2A has ahole 5 in the fixingflange 8, in the form of a through hole or a blind hole for the above engagement with thepen point 3. Alternatively (not shown), thehole 5 may be formed in the holdingpart 7. - According to an embodiment as shown in
Fig. 2C , there is ahole 5 in the form of a blind hole in the clip, so formed that thepen point 3 can be caused to engage the boundary surfaces of the hole. Also in this embodiment, the hole may have a cross-section varying in depth. - With reference to
Fig. 6 , one more embodiment of a pen according to the invention is shown, in which thepart 4, which is removably arranged on thepen body 1, is aprotective cap 11 with aclip 4. This clip may, like in the embodiments described with reference toFigs 1-4 , have ahole 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 theprotective cap 11, or as a separate part. - An alternative is shown in
Fig. 7 , viz. acap 11 with anengaging hole 5 in its one, normally closed end. It will be appreciated that thehole 5 can either be a blind hole or a through hole, and that thebole 5 can be arranged in an arbitrary position in thecap 11. - With reference to
Fig. 8 , which shows one end of a cap with aclip 4, seen from the open end of the cap, there may be formed according to a further alternative, on the underside of theclip 4 at its distal end, a projection with ahole 5 for engaging the pen point projecting from the pen body. Alternatively or besides (not shown), the projection can be formed on the pen body to define saidhole 5. For removing the pen point or the ink stick, the pen point can be inserted into thehole 5, after which thecap 11 and thepen body 1 are angled to each other to provide the engagement similarly to the above embodiments involving a through hole or a blind hole. - Finally, it should be emphasised that the invention is not limited to the embodiments described and may be varied within the scope of the appended claims.
