TECHNICAL AREA

The invention relates to a nib for fountain pen having a

Spring tip and a capillary recess for directing ink from one

Touch area for an ink conductor to the nib. The invention further relates to a nib part for fountain pens with a feed block and a nib. The invention also relates to a fountain pen with a

Ink guide, a pen attached to the ink guide and a

Füllfederhaltergehäuse. BACKGROUND OF THE INVENTION

Nibs per se and nibs for fountain pens in particular have long been known and have already experienced a fairly strong diversification. Essentially, however, nibs typically have the same

basic features, through which a reliable supply of ink from an ink container connected to an ink carrier ink conductor is made possible only on the paper to be described. Thus, a nib of fountain pen in the prior art has a spring slot extending from a contact area for an ink conductor or a region near a mounting portion to a

Spring tip extends and acts as a capillary due to its tuned slot width. Arranged on the ink conductor, the ink stored in an ink tank is conveyed via the spring slot to the nib and from there onto the paper. The spring slot is very fine for common ink viscosities and is within a small range of a tenth of a millimeter. In addition to the

Capillary action is the spring slot also responsible for an elasticity of the nib. The preparation of a writing pen of the prior art provides, a

To write pen in the raw state of the pen tip, wherein the spring slot can open into a so-called heart hole. By the spring slot two separate and juxtaposed spring legs are formed, which can move relative to each other.

Known nibs have excessive mechanical pressure when

Write down the behavior that the spring legs move relative to each other, so that widens the spring slot. In the case of a purely planar spreading, the spring gap towards the spring tip would have an increasing width approximately from the heart hole. The design of the spring slot for a given ink type with a corresponding viscosity and a corresponding Cohesion behavior leads to spreading of the spring legs continue to retire that formed in the spring gap so-called ink meniscus, since the capillary effect with too large a distance of the spring legs to each other

collapses and thereby the pen tip can not be supplied with ink.

In addition to the spring slot also influences the making of ornaments,

Cutouts and Ziselierungen directly in the nib of the spring absorbable force, so that sometimes the material used for the production of the nib, the geometry and material thickness must be adjusted or selected accordingly. However, this often comes at the expense of an attractive appearance, so that in particular pens for high-quality writing instruments often have no elaborate outs and incisions. Due to the widespread use of gold alloys for higher quality

Fountain pen is due to the low strength and geometry and by the additional slotting only a relatively low typist compatible.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a nib for fountain pens

to propose that has a nib and a capillary for guiding ink from a contact area for an ink conductor to the nib and allows a greater creative freedom with openings, cutouts, incisions, openings or the like at the same time higher typist.

The problem is solved by a nib with the characteristics of

independent claim 1. Advantageous developments are given in the dependent claims. The gist of the invention is to provide the nib with a nib and a capillary recess for directing ink to the nib, the capillary extending from a contact area for an ink conductor to the nib. According to the invention, however, the spring tip is not severed by the capillary recess. This means, in other words, that the pen according to the invention, like all known nibs has a capillary, which directs ink to a nib, which then emits ink by sliding on paper. Due to the lack of transection, no two separate spring legs, which at

Stress with a higher typist tend to spread, resulting in retraction of the ink meniscus. According to the invention, the sections defined by the capillary recess of the pen according to the invention, which could also be referred to as spring legs for the sake of simplicity, are at one end over the not severed spring tip among all

conventional stresses occurring associated with each other and therefore can not move apart practically.

In the context of the invention, the device referred to as Kapillarausnehmung can be realized in different ways. In an advantageous embodiment of the invention, the Kapillarausnehmung is at least partially designed as a groove, which by definition forms a recess or elongated notch in the material of the nib and having a bottom. The groove is to be dimensioned such that a conventional ink to be used can be easily directed towards the tip of the pen and at the same time prevents dripping and, for example, likewise has a width of approximately one tenth of a millimeter, preferably also a depth of the same order of magnitude. The groove could be made by a forming process, such as by pressing or grooving / scoring / notching, but also by machining methods such as milling, grinding or by a laser ablation process. In an advantageous embodiment of the invention, the Kapillarausnehmung is arranged on an underside of the nib, which means that the top of the nib can be designed practically independent of Kapillarausnehmung and the nib of the invention may also have ornaments, cutouts, cuts or Ziselierungen that otherwise would be disturbed by running in the nib spring slot.

In an advantageous embodiment of the invention, a spring grain is arranged on the spring tip, which is not severed. The spring grain may have on its underside a groove or a depression, which in the

Kapillarausnehmung the remaining part of the pen according to the invention opens. As a result, the writing behavior of the pen of the invention compared to conventional nibs is practically not affected. The feather grain often consists of a very hard, wear-resistant metallic material, for example based on an iridium alloy.

In an advantageous embodiment of the invention, the Kapillarausnehmung is at least partially designed as a spring slot. This will be the

Production of a pen according to the invention simplified, since only a part of the pen according to the invention must be processed differently than in the prior art usual.

According to an advantageous embodiment of the invention, the nib has a cutout that can be virtually any shape and from a

Bottom extends to an upper side of the nib according to the invention. The capillary recess extends in a region of the nib, in which the cutout is not. The cutout is primarily for the purpose of giving the nib a pleasing appearance, wherein the ink conduit is realized independently of such a cutout design. According to an advantageous embodiment, the cutout ends in a

Herzloch and can thus in addition to the attractive shape of a

Avoid damaging the spring in the event of excessive stress while at the same time filling a significant area of the nib.

In an advantageous embodiment of the invention, the cutout opens into the KapiUarausnehmung. The ink line can therefore be realized in places over a section, which particularly the optical design of the

A writing lead from an ink conductor via a KapiUarausnehmung and a derivative of the pen tip can also be realized by a KapiUarausnehmung, which could be arranged for example on the underside of the pen according to the invention and designed as grooves. Can the neckline or the Ziselierung or the like a

can provide sufficient capillary action to direct the ink, the

KapuUarausnehmung be replaced in places hereby. This can be a completely unknown in the prior art combination between a

Ornamental neckline and a capillary are made possible. In an equally advantageous embodiment of the invention, the nib has two Kapillarausnehmungen, which open into the nib. These

Kapillarausnehmungen can run at the edge of the underside of the nib and from a common starting point in one

Turn contact area for an ink conductor to the edge sides to the outside and then merged in the pen tip or adjacent leakage under spatial separation from each other. So one is completely

independent cut-out or skeletonization of a central region of the pen of the invention possible without affecting the flow of ink thereby. For this, it should be noted that the ink conductor corresponds to the Off-centered Kapillarausnehmungen must be adjusted in order to ensure a sufficient inflow of ink into the Kapillarausnehmungen.

The object is further achieved by a pen nib for fountain pen, which has a feed block and a nib with the above

Features.

Finally, the object is also achieved by a fountain pen having an ink guide, a nib and a fountain pen housing.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Fig. La shows a writing spring 2 according to the invention in a plan view. The nib 2 according to the invention has a mounting portion 4, with which the nib 2 can be inserted together with an ink conductor in a fountain pen housing to enter into a mechanical connection. In a contact region 5, the nib 2 according to the invention can be a

Fluid communication with an ink exit slit of the ink conductor, so that ink from the ink container via capillary forces in the inventive

Quill 2 can be pulled. The nib 2 according to the invention has at its end opposite the mounting portion 4 a spring tip 6, which is equipped with a spring 8. This is preferably from a relative hard, wear-resistant metal alloy formed which does not wear when writing with the pen nib 2 according to the invention on paper as possible. Furthermore, the writing nib 2 according to the invention in the representation of FIG. 1a has a spring slot 10 which opens into a so-called heart hole 12.

As can be clearly seen, the slot 10 extends from the heart hole 12 to the spring bead 8, but this does not cut through it differently than in the prior art. The writing spring 2 according to the invention therefore has two spring legs 14 and 16, which are indeed separated by the spring slot 10, but at its end remote from the heart hole 12 by the spring 8 are firmly connected to each other. Now acts a strong typist force on the spring 8 and thus on the two spring legs 14 and 16, although occurs a bending of the nib 2, which does not lead to a spreading of the two spring legs 14 and 16. As a result, a fairly high typist can be guaranteed, which would be sufficient, for example, to achieve a breakdown on a carbon paper or the like on a second sheet of paper.

As shown in Fig. 1 b using the underside of the pen nib 2 according to the invention, always a capillary between the spring slot 10 and the spring bead 8 must be created so that ink from a

Touch area 5 for an ink conductor, in which the heart hole 12 is arranged, can be passed from the slot 10 in the spring core 8 and thus on the paper. For this purpose, a groove 18 is attached to the spring bead 8, with the

Spring slot 10 is connected. The groove 18 could be made, for example, by sawing, grinding, etching or a laser ablation process.

Fig. 2a and 2b show a further embodiment in the form of a

Inventive nib 102, which also has a heart hole 1 12 in a touch area 105 for a Tinenleiter, but without one

Spring slot. Instead, at the bottom of the writing spring 102 according to the invention, as shown in Fig. 2b, a groove 120 is arranged, which from the heart hole 1 to 12 extends to a spring bead 108 and there opens into a groove 1 18 in the spring grain. So that the groove 1 18 has the same capillary properties, it is necessary to adapt the dimensioning of a spring slot 10. Accordingly, the width of the groove could be approximately in a range of 0.04 mm-0.2 mm, while the depth of the groove corresponds thereto, depending on the thickness of the writing spring 102. By replacing the spring slot 10 with a groove 120, the optics of the writing nib 102 according to the invention are almost unaffected by the technically necessary features for conducting ink. It should be noted at this point that the heart hole 1 12 at the

Inventive nib 102 is not absolutely necessary.

The variable design capability is further enhanced in the inventive nib 202 in FIGS. 3a and 3b, which has a completely clean surface as shown in plan view in FIG. 3a. However, on its underside, according to FIG. 3b, a groove 220 is arranged, which extends from a contact area 205 for an ink conductor to a spring grain 208 and opens into a groove 218 there.

As a result, both a very high writing force can be applied to the spring, without the ability of an ink line is interrupted, as well as a very large creative scope at the top of the writing spring 202 according to the invention are provided.

In detail, according to the plan view in Fig. 4a, a cutout 322 at the top of a writing spring 302 according to the invention can be arranged, which can be configured in Fig. 4a, for example, as a centrally disposed on the writing spring 302 letter or an initial.

As shown in Fig. 4b in the bottom view, the cutout 322 extending from a contact area 305 for an ink conductor to the spring tip 308th down and there open in a groove 318 groove 320 interrupt and thereby partially act as a slot or a capillary. This means that the groove 320 at the bottom of the writing spring 302 according to the invention, although interrupted, is completed by the cutout 322 again. If the cutout 322 is to be part of a capillary, its dimensions must correlate at least in the region that overlaps the groove 320.

Another embodiment of FIGS. 5a and 5b shows a

Inventive writing spring 402, the heart hole 412 in one

An ink guide contact area 405, two cutouts 422, and a groove 420, wherein the groove 420 on the underside of the spring 402 as shown in Fig. 5b extends from the heart hole 412 to the spring bead 408 and there into the groove 418. The cutouts 422 are off-center, but arranged symmetrically to each other and do not affect the capillary function of the groove 420.

Although the cutouts 422 form a weakening of the invention

Nib 402, but there is no slotting of the spring. The writing pen 402 according to the invention can therefore still handle higher typists than would be possible with conventional writing springs from the prior art.

An equally advantageous other development is shown in Figs. 6a and 6b, in which an elaborate cutout 524 is disposed centrally of the spring 502, wherein the cutout 524 is still not part of a Kapillarausnehmung.

As shown in Fig. 6b in a view of the underside of the writing nib 502 according to the invention, two non-rectilinear grooves 526 are provided, which extend from an area 505 for an ink conductor around the cutout 524 while ink to the nib 508 and there in the Guide groove 518. Alternatively, both grooves 526 may open into two spaced apart, preferably parallel, grooves 518 adjacent to each other. This is clearly that the technical features of the invention, a very large creative freedom is created to skeletonize a quill quite strong and to customize, but still be able to provide a high stability, which allows writing even with very high typists who over those may lie of nibs, which are known from the prior art.

7a and 7b show an exemplary embodiment of a writing spring 602, in which a cutout 622 in the form of a clef is provided, which is connected to a groove 620 which is directed toward a spring 608 and which fits into a groove 618 of the groove

Federkorns 608 opens. A part of the cutout 622 is shaped so that it can take over the function of a spring gap. The cutout 622 is further connected to a heart hole 612 disposed in a contact area 605 for an ink guide.

8 further shows a writing spring part 702, on which a writing spring 704 according to the invention is applied and has a connecting region 706 for connection to a fountain pen housing. Finally, FIG. 9 shows a fountain pen 802, which has a nib portion with a writing nib 804 according to the invention and a fountain pen housing 806.

In addition, it should be noted that "having" does not exclude other elements or steps, and "a" or "an" does not exclude a multitude, and it should be noted that features that are described with reference to any of the above

Embodiments have been described, can also be used in combination with other features of other embodiments described above. Reference signs in the claims are not to be considered as limitations.
