Description

Technical Field

[0001] This invention relates to a writing instrument, particularly a fountain pen, comprising a nib and, particularly, a writing portion having the nib, the writing portion accommodating a (elongated) writing medium reservoir, particularly an ink reservoir containing ink, and including a detachable removal aid connected to the writing portion for assisting in removing such a provision or provision in the writing portion of the writing medium reservoir, the removal aid having a receiving space, particularly a hollow cylindrical shape, for a connectable section of the writing medium reservoir, preferably located at the end, and one or more connecting members for detachably connecting the removal aid to the connectable section of the writing medium reservoir. Background Technology

[0002] Writing instruments including removal aids are known in the prior art, which facilitate the removal of an ink-filled ink reservoir. For example, JP 5448250 B2 illustrates a removal aid as a cap covering the pen tip at the front of the writing instrument. This cap is correspondingly detachably connected to the writing part of the writing instrument and, in its detached state, can be used to disengage the threaded ink reservoir, screwed into the writing part, from the screwed-on state or to unscrew it from the writing part. For this purpose, the ink reservoir has ribs at the connectable section, i.e., the rear end, which rest against a connecting member of the cap, which is constructed as a channel. This achieves a (temporary, detachable) form-locking connection between the cap and the ink reservoir, and more precisely, it achieves such that by rotating the cap, rotational force can be transmitted to the rear end of the ink reservoir, ensuring that the ink reservoir automatically gains axial movement out of the writing instrument based on the here-detached threaded connection between the ink reservoir and the writing part. A particularly disadvantageous aspect of this solution is that the use of the removal aid shown therein forces the assumption that the ink reservoir is screwed into the writing instrument via a threaded connection. Conversely, standard reservoirs with substantially smooth surfaces and, in particular, without threads, cannot be used. However, manufacturing ink reservoirs with (external) threads is expensive and complex. Summary of the Invention

[0003] Therefore, the objective of this invention is to further improve the writing tool of the type described at the beginning.

[0004] This task was solved using a writing tool.

[0005] Therefore, according to the present invention, the writing instrument described at the beginning is characterized in that the connecting parts, or each connecting part (each of the "multiple" connecting parts of the retrieval aid considered: this may be, but is not necessarily, all the connecting parts of the retrieval aid that contribute to a detachable connection), are constructed such that the retrieval aid is frictionally locked to or detachably connected to the writing medium reservoir when the connecting parts are abutted against the connectable section of the writing medium reservoir, especially when the wall of the connectable section of the writing medium reservoir is deformed by the connecting parts, preferably when the deformation causes an additional detachable topographic locking connection between the retrieval aid and the connectable section.

[0006] The removable friction-locking connection between the removal aid and the writing medium reservoir, according to the present invention, further enables the removal of standard ink reservoirs from the writing section using such a removal aid, unlike prior art. These standard ink reservoirs are often made of plastic containers with a more or less smooth outer surface (and especially without threads). This is achieved even when the ink reservoir may not be easily or barely held by the user's hand.

[0007] However, the solution according to the invention can also be conceived in other writing instruments, including fountain pens which may optionally contain other writing medium reservoirs. For example, various other writing instruments include writing medium reservoirs containing very different, particularly water-based and / or paste-like, writing media, such as ink, gel, etc.

[0008] The writing portion constitutes, or preferably within the scope of this application, one or more of, the writing instrument, on which the user grips the writing instrument for writing.

[0009] Of course, the pen tip, for example in a fountain pen formed by the pen tip, can be directly and fixedly mounted on and connected to the writing part. However, the pen tip can also be, for example, a component of a writing medium reservoir (detachably mounted in the writing part).

[0010] When the writing medium reservoir is installed in the writing instrument or the writing part of the writing instrument in a friction-locked connection with the removal assist, the user can, for example, detach the removal assist, which is detachably connected to the writing part, from the writing part to replace the writing medium reservoir. Then, the user can completely remove the removal assist, along with the writing medium reservoir (which is still detachably connected to the removal assist at that moment), from the writing part, and the writing medium reservoir will be automatically and completely pulled out of the writing part automatically, without first forcibly contacting the writing medium reservoir. Subsequently, the user can, for example, detach the writing medium reservoir from the removal assist in the next step next to the writing part, insert a new (optionally even one that the user has detachably connected to the removal assist) writing medium reservoir into the writing part, and then reconnect the removal assist to the writing part.

[0011] Regarding the removal aid device or each connecting component, the removal aid device may have an inner side that surrounds (and defines) a receptacle for a connectable section for a writing medium reservoir, particularly a side that is substantially circular or round in cross-section or substantially (particularly regular) polygonal in cross-section, wherein the inner side or each connecting component is formed by the inner side and / or by (optionally each) a particularly flat section of the inner side and / or the inner side is provided, particularly formed, on the inner side, especially when it is one-piece connected to the inner side.

[0012] In other words, the inner side of the surrounding structure itself (optionally one or more segments of the inner side) may form the aforementioned or each connecting component.

[0013] Only, for example, may be specified herein, that the inner side of the surrounding (polygonal in cross-section in this example) or the inner contour of the receiving space is square or rectangular in cross-section (optionally including rounded corners). A detachable friction-locking and form-locking connection can be achieved in such a way that the outer contour of the connectable section of the writing medium reservoir is suitably adapted to the inner contour of the receiving space or to the inner side of the surrounding (e.g., in a way that the connectable section is constructed in the shape of a right parallelepiped or its outer contour is correspondingly square or rectangular in cross-section), such that the connectable section or its outer side can be introduced into the receiving space with an interference fit when it abuts against the inner side of the surrounding or each of the four flat or unbent sections of the inner side.

[0014] However, it is also particularly preferred that the inner side be shaped such that the inner side respectively forms one or more tabs or ribs, the one or more tabs or ribs forming each / every connecting component.

[0015] However, it can also be stipulated that the inner side itself does not form the or each connecting component, but rather one or more separate connecting components are disposed on the inner side. In this way, the or each tab / rib may also be constituted as itself or a separate component and fastened to the inner side.

[0016] It can be generally stipulated that the aforementioned or each connecting component, when configured as a tab or rib, extends into the receiving space.

[0017] Each or every tab / rib may also be oriented parallel to the longitudinal (central) axis of the writing instrument and / or the removal aid.

[0018] When the retrieval aid has multiple connecting parts, it can be specified that the connectable sections of the writing medium reservoir, for example in the state where the writing medium reservoir is connected to the retrieval aid, are respectively arranged in the receiving space of the retrieval aid between optionally multiple pairs of connecting parts that are respectively (more or less) opposite each other in the receiving space, and more precisely in the case of radial or lateral pressing, so that the ink reservoir is thereby held, especially in the axial direction, and cannot be moved axially out of the retrieval aid.

[0019] Preferably, the writing medium reservoir or the connectable section can also be held or fixed in the radial direction relative to the retrieval aid, so that relative rotation between the retrieval aid and the ink reservoir is not possible.

[0020] When the connecting parts are constructed as tabs or ribs as described above, the connecting parts are particularly preferably evenly distributed on the inner side of the column, and more precisely, adjacent connecting parts have an angular distance from each other, which is the same in all adjacent connecting parts.

[0021] Each of the connecting components may also be elongated and oriented parallel to the central longitudinal axis of the extraction aid.

[0022] If we are referring to the removal aid in a completely general sense, it is also conceivable that the removal aid is an injection-molded part made of plastic.

[0023] If a detachable connection is involved between the writing section and the retrieval aid, they can preferably be screwed together.

[0024] This can be achieved, for example, by means of a threaded connection having threads, particularly external threads, on the extraction aid and particularly internal threads, on the writing part, wherein, in order to connect the extraction aid and the writing part, the threads of the extraction aid are screwed into the threads of the writing part. Preferably, the external threads of the extraction aid are screwed into the internal threads of the writing part.

[0025] Further preferably, according to the invention, each connecting component is constructed in such a way, and particularly in coordination with a writing medium reservoir mounted in or provided for the writing portion, that a detachably frictionally locked connection is achieved or can be achieved between the removable aid and the connectable section of the writing medium reservoir, particularly the ink reservoir, during the connection, particularly the screwing, of the removable aid and the writing portion (and optionally, additionally, deformation of the connectable section or the resulting form-locking connection). This is particularly true during the screwing of the removable aid into the threads of the writing portion, after the removable aid has been previously received in the receiving space of the removable aid in the connectable section, by the user onto the writing medium reservoir, particularly the ink reservoir, or its connectable section, or after the removable aid has been fitted onto the writing medium reservoir or its connectable section in this manner.

[0026] The friction locking and optionally additional terrain locking connection is achieved or can be achieved by the following manner: the removal aid or each connecting component is at least partially inserted into the wall of the connectable section of the writing medium reservoir during connection or screwing, so that the writing medium reservoir is held in the receiving space of the removal aid in the axial direction, especially by lateral or radial pressing, as described above.

[0027] Within the range of access, a recess extending particularly in the axial direction or parallel to the longitudinal (central) axis of the writing instrument may be formed for each connecting component, for example, in the connectable section of the writing medium reservoir, with the corresponding connecting component resting in the recess.

[0028] Preferably, the connection, which induces frictional locking and optionally additional topographic locking during or through the linear and / or axial relative movement of the writing medium reservoir and the retrieval aid, is located within the wall of the connectable section of the aforementioned writing medium reservoir, particularly the ink reservoir. When the writing portion and the retrieval aid are interconnected, for example, by screwing as described above, the resulting linear or axial relative movement components between the writing portion and the retrieval aid may ensure, preferably only ensure, that the or each connecting component moves linearly and / or axially along the connectable section, particularly in the case of deformation forming the connectable section, preferably in the case of forming a corresponding recess.

[0029] Optional additional deformations of the connectable sections or optional additional form-locking connections with the writing medium reservoir, especially the ink reservoir, can additionally cause sufficient fixation or tightening of the writing medium reservoir relative to the retrieval aid in the radial direction after the connection process or optional threaded connection process is completed, so that the writing medium reservoir automatically rotates together with the retrieval aid, especially during the user's (optionally further or subsequent) rotational movement, and completely or minimally prevents relative rotation between the writing medium reservoir and the retrieval aid.

[0030] Regarding the extended design of the extraction aid, the extraction aid is preferably a component of, or forms, a cap-shaped end member that is detachably connected to the writing part at the rear of the writing instrument, particularly via the aforementioned threaded connection. Here, the cap-shaped end member is detachably connected to the writing part on the side opposite to the side where the pen tip is located.

[0031] Furthermore, the construction of the writing instrument or retrieval aid according to the present invention enables the realization of specific proportions of the various components of the writing instrument.

[0032] Therefore, it can be stipulated that (in the state of interconnection between the end component and the writing part), the longitudinal (axial) extension dimension of the outer side of the end component from the free end of the rear part of the end component to the end of the end component adjacent to the writing part is less than half, preferably less than 7 / 16, of the longitudinal (axial) extension dimension of the writing part from the end of the writing part adjacent to the end component to the pen tip.

[0033] Furthermore, the writing portion may be specified to have a receiving space for a writing medium reservoir, at least laterally surrounded by the walls of the writing portion—particularly open towards the (rear or rearward) receiving side. Preferably, this receiving space, in the case of an ink reservoir (for ink or similar writing media), has a piercing mandrel for the ink reservoir, through which the writing medium reservoir can be introduced. This receiving space may be directly adjacent to the receiving space of the retrieval aid, either directly or via a connecting gap.

[0034] Furthermore, it can be specified that when the writing medium reservoir is in a position for using a writing instrument within the receiving space of the writing portion, especially in a position where the writing medium of the writing medium reservoir can be guided to the pen tip, the writing medium reservoir does not protrude from the receiving space (in the direction of removing the auxiliary device) by at most half of its length, preferably at most one-third of its length, and particularly preferably at most one-quarter of its length.

[0035] The relatively small protrusion or complete submersion of the writing medium reservoir, especially the ink reservoir, within the receiving space makes it either poorly grippable or completely ungripable by hand for the user. However, with the aid of a removal device (to which the writing medium reservoir, especially the ink reservoir, is detachably connected), the writing medium reservoir can be easily removed by the user.

[0036] When the writing medium reservoir is positioned in the receiving space for use of a writing instrument, especially when the writing medium in the writing medium reservoir can be guided to the pen tip, the connectable section of the writing medium reservoir can be fully or partially located in the receiving space of the writing portion.

[0037] Alternatively or additionally, the connectable section may (in this position of the writing medium reservoir) be spaced apart from the free rear end of the writing medium reservoir (especially in the receiving space of the retrieval aid) by an end section of the writing medium reservoir having the free end, the retrieval aid being connected in particular based on the radial distance between the end section and each connecting member, without frictional locking with the end section and optionally additionally topographically locked.

[0038] In other words, the frictional engagement or optionally the form-locking engagement is achieved not in the end section of the writing medium reservoir directly above the free end of the writing medium reservoir, but in a region spaced apart from the free end of the writing medium reservoir.

[0039] Finally, regarding the writing medium reservoir (or optionally the ink reservoir) itself, as explained above, it is preferred that at least the portion of the writing medium reservoir having the connectable section, but particularly preferably the entire ink reservoir, be made of a plastic that is especially deformable, preferably elastic. Attached Figure Description

[0040] Other features of the invention will become apparent from the following description of preferred embodiments and the accompanying drawings.

[0041] Here:

[0042] Figure 1 A simplified longitudinal sectional view of the writing instrument according to the present invention is shown;

[0043] Figure 2 A partial sectional perspective view of the writing instrument according to the present invention is shown. Detailed Implementation

[0044] The writing instrument 10 shown is currently known as a fountain pen. The fountain pen, in particular, includes a nib 11 (currently made of metal) with a nib 12 in the area at its front or at its front end.

[0045] The pen tip 11 is a component of the writing portion 13 of the writing instrument 10, which has a housing 17 that functions as a gripping part and can be gripped by the user during writing. The housing 17 also has a receiving space 14 in which an elongated writing medium reservoir, currently configured as an ink reservoir 15, is mounted on a pierced spindle 16 in a known manner.

[0046] The ink is in the ink reservoir 15, and the ink is guided to the pen tip 11 and therein, in particular, to the pen nib 12, in the same known manner via ink guide channels, etc.

[0047] Of course, as mentioned at the beginning, although the present invention is illustrated with the example of a fountain pen, it is not limited to such a fountain pen. The present invention can also be used with other writing instruments, which may optionally also have another type of writing medium reservoir.

[0048] The writing instrument 10 shown has a cap-shaped end member 18 at its rear end, which is detachably screwed to the writing part 13, i.e., screwed to the end of the writing part 13 or the housing 17 of the writing part 13 facing the end member 18, and more precisely screwed to the end member 18 via a threaded connection 21.

[0049] Here, the end component 18 for this purpose has a hollow cylindrical pin 19 located at the end, which is fitted into a cooperating, in particular, hollow cylindrical pin receiving portion 20 of the rear end of the housing component of the housing 17.

[0050] The pin 19 and the pin receiving part 20 are then connected by an external thread on the pin 19, which is screwed into a mating internal thread provided in the pin receiving part 20 or screwed in for subsequent connection of these components in the initially unconnected state.

[0051] Specifically, in this case, the internal thread of the pin receiving portion of the housing 17 is provided on or machined into the inner side of the pin receiving portion 20, which is particularly cylindrical.

[0052] Of course, the threaded connection 21 may also be constructed differently. For example, it is conceivable that the end member 18 has an internal thread and the writing portion 13 has an external thread.

[0053] The pin receiving part 20 forms the end portion of the receiving space 14 of the housing 17 of the writing part 13, which has an open (end-facing) receiving side in the unconnected state of the end member 18 and the writing part 13, through which the ink reservoir 15 is introduced into the receiving space 14.

[0054] End member 18 also has (especially a substantially cylindrical) receiving space 26, in contrast Figure 1 and 2 The rear portion of the ink reservoir 15 is positioned within the receiving space in the connected state of the end member 18 and the writing portion 13. The receiving space 26 here comprises the internal space currently including the pin 19 of the end member 18 and another internal space segment flush with which the end member 18 is connected.

[0055] It is of particular importance now that the end component 18 is currently configured as an extraction aid for easily removing the ink reservoir 15 from the housing 17 of the writing section 13, so that the ink reservoir 15 can be easily replaced when needed.

[0056] As in Figure 1 and 2 As can be seen, the ink reservoir 15, in the proportion selected for the writing instrument 10, protrudes from the receiving space 14 at most 1 / 4 of its length in the position where ink can be dispensed, so that the user may only be able to grip the ink reservoir poorly at the rear end or the user may find it difficult to apply enough force.

[0057] To facilitate the removal of the ink reservoir 15, the end member 18 currently has a plurality of elongated, ribbed connecting members 27 extending axially. These connecting members are arranged around the perimeter and angularly spaced from each other on the inner side of the receiving space 26. The inner side is currently formed by corresponding shaping of the inner side, extends into the receiving space, and forms a detachable connection with the (rear / currently also cylindrical) section 25 of the ink reservoir 15 that is connectable to these connecting members.

[0058] Currently, the connecting member 27 here defines a slightly narrower portion of the receiving space 26, and more precisely, the space is narrowed relative to the radially rearward (and further radially outwardly disposed) sections that surround the inner side of the receiving space 26.

[0059] Of course, the connecting parts can also be constructed differently. Of particular importance is that the detachable connection is generally configured such that, on the one hand, when the end part 18 is removed from the writing part 13—after unscrewing the threaded connection 21 or after disengaging the threaded connection—the ink reservoir 15 automatically moves with the end part 18 and is pulled out of the receiving space 14 of the writing part 13; but on the other hand, the user can then easily manually detach the connection so that the ink reservoir 15 can be separated from the end part 18 again.

[0060] For this purpose, the diameter of the narrowed portion of the space defined by the connecting member 27 is coordinated with the connectable section 25 of the ink reservoir 15 (in particular the outer diameter of the connectable section) so that the connectable section is held at least frictionally in the receiving space 26 under radial or lateral pressure (interference with respect to the narrowed portion of the space), but is also currently held in a form-locking manner in the receiving space, as will be explained later.

[0061] However, in a very simple case, when the diameter of the receiving space 26 defined by the connecting member is coordinated with the connecting segment 25 at least in the region of the connecting segment 25 such that the connecting segment can be press-fitted into the region, it is possible, alternatively, to theoretically also abandon such a ribbed connecting member 27 and only the (perhaps smooth) inner side of the receiving space 26 functions as the connecting member.

[0062] Furthermore, the connectable section 25 of the ink reservoir 15 currently does not have the free end of the ink reservoir 15 located in the receiving space 26 of the end member 18, but is separated from that free end by the end section of the ink reservoir 15 having that free end, wherein the connecting member 27 is radially spaced from the end section and there does not correspondingly abut against the ink reservoir 15 or the end section, nor does it form a connection there. This is because the ink reservoir 15 is tapered in that end section or has a smaller outer diameter than the connectable section 15. But of course, the connectable section 25 may also—in the case of including the free end—extend to that free end of the ink reservoir 15.

[0063] In the current application of the ribbed connecting member 27, the wall of the connectable segment 25 is additionally, advantageously, deformed radially inward, perhaps almost imperceptibly, by the connecting member 27 in such a manner that the connecting member 27 slightly penetrates into the wall of the connectable segment 25, resulting in a form-locking connection in addition to the friction-locking connection (the connecting member 27 acts in or abuts against the connectable segment 25 in said location). This form-locking additionally prevents relative rotational movement between the connectable segment 25 on one side and the end member 18 on the other side.

[0064] The connecting member 27 is further configured and coordinated with the ink reservoir 15 such that the state in which the ink reservoir 15 is already disposed in the writing portion 13 or the receiving space 26 of the writing portion causes, or—in proper operation—at least may cause, the aforementioned connection of the connectable section 25 to the ink reservoir 15 during the screwing of the end member 18 and the writing portion 13.

[0065] In practice, when the connecting part 27 or the connecting part is coordinated with the ink reservoir 15, after the user has previously fitted the end part 18 into the receiving space 26 in the connectable section 25 and onto the ink reservoir 15 or the connectable section 25 of the ink reservoir, or after the end part 18 is fitted into the ink reservoir 15 or the connectable section 25 of the ink reservoir in this way, the user may subsequently screw the end part 18 onto the writing part 13, thereby causing the friction-locked and currently additional terrain-locked connection.

[0066] Currently, within the range of linear and / or axial relative movements generated in the threaded connection of the writing portion 13 and the end member 18 (or correspondingly the reservoir 15 and the end member 18) (outside of or during relative rotational movement), each connecting member 27 enters into the connectable section 25 or the (outer) wall of the connectable section, and more precisely, in the case where corresponding elongated recesses are formed, parallel to the longitudinal extension orientation of the reservoir 15 or the writing instrument 10, the corresponding connecting members 27 then rest in the recesses to terminate the threaded connection.

[0067] In this way, the ink reservoir 15 is correspondingly held in the receiving space 26 of the end member 18 by lateral or radial pressing in the axial direction.

[0068] Additional deformation of the connectable section 25 or additional form-locking connection with the ink reservoir 15 further achieves sufficient fixation or fastening of the ink reservoir 15 relative to the end member 18 in the radial direction, so that the ink reservoir 15 automatically rotates together with the end member 18, especially in the (further or subsequent) rotational movement of the user, and completely or largely prevents relative rotation between the ink reservoir 15 and the end member 18.

[0069] Alternatively to the above-described manner of causing the connection, the user may theoretically establish the connection fully or partially by inserting the ink reservoir 15 with its rear end into the end member 18 with sufficient axial force while the writing portion 13 and the end member 18 are unconnected, or by pushing the ink reservoir until the connectable section 25 is connected to the connecting member 27 in the manner described above.
