DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] With reference to FIGS. 1 to 6, the embodiments of the present invention are described. The description does not limit the scope of the embodiments but is one of the embodiments of the present invention.

[0021] FIG. 1 to FIG. 5 illustrate an omnibearing writable fountain pen according to the first embodiment of the present invention, comprising: a shaft component 1 in which an ink reserve chamber 11 is contained; a feed component 2 arranged at the front end of the shaft component 1 to deliver ink reserved in the ink reserve chamber 11; a nib component 3 including two nibs 31a, 31b, each nib 31a, 31b having a middle slit 32, the two nibs 31a, 31b being stacked with each other in such a manner that a horizontal gap 33 is disposed between the two nibs 31a, 31b so as to form a nib tip 34 having at least four ink channels 32a, 33a in a front end of the two nibs, wherein each ink channel 32a, 33a is connected through the middle slit 32 and the feed component 2 to the ink reserve chamber 11.

[0022] In this embodiment, the nib component 3 is two detachable nibs 31a, 31b in order to facilitate the cleaning and maintenance of the nib component 3. The nib tip 34 at the front end of the two nibs 31a, 31b is Iridium point which is in form of a sphere in such a manner that the writing feeling remains the same no matter what writing angle and direction are. In the other embodiments, however, the nib tip 34 can also be in form of an ellipsoid or other shapes in order to create line variety through shape-changing of the nib tip 34.

[0023] Moreover, the middle slit 32 and the horizontal gap 33 of the omnibearing writable fountain pen 100 according to the first embodiment of the present invention, as shown in FIG. 2 to FIG. 5, can both produce capillarity so as to attract the ink-flow to the nib tip 34 by means of the adhesion of the ink to the side wall surface of the middle slit 32 and the horizontal gap 33. The middle slit 32 extends along the center line of the nibs 31a, 31b to form the ink channels 32a on the front and rear sides of the nib tip 34 and the horizontal gap 33 forms the ink channels 33a on the left and right sides of the nib tip 34, these ink channels 32a, 33a being communicated with the ink reserve chamber 11 in such a manner that the front, rear, left and right sides of the nib tip 34 can have ink-flow. This advantageous characteristic combining with the adhesive force between ink and paper makes the omnibearing writable fountain pen of the present invention omnibearing writable

[0024] More specifically, the middle slit 32 and the horizontal gap 33 are disposed perpendicular to each other. The two ink channels 33a formed on the sphere by the horizontal gap 33 extends along a bisecting line of the sphere to bisect the sphere into two hemispheres located on the upper nib 31a and the lower nib 31b respectively; The two ink channels 32a formed on the sphere by the middle slit 32 extends along a center line of the nibs 31a, 31b to bisect the two hemispheres. As a result, a uniform distribution of the four ink channels 32a, 33a appears on the nib tip 34. In the other embodiments, however, more than three nibs can also be stacked with each other in such a manner that more than four ink channels can be formed on the nib tip 34.

[0025] As shown in FIG. 5, the omnibearing writable fountain pen 100 according to the first embodiment of the present invention, an angle between two side wall surfaces, in up and down direction, of the ink channel 32a formed at the upper nib 31a is between 0200 and 0300. The two side wall surfaces of the ink channel 32a formed at the lower nib 31b can be parallel or form, in up and down direction, an angle between 0200 and 0300. As a result, there is a writing line thickness difference between writing right side up and writing upside down when using the omnibearing writable fountain pen 100 of the present invention, because of the difference existing in contact area between the nib tip 34 and paper and in volume of attracted ink-flow. Of course, depending on a special need of a user for writing line thickness in a certain orientation, the side wall surfaces of one or more corresponding ink channels 32a, 33a can be parallel or form an angle within an angle range between 0200 and 0300.

[0026] As shown in FIG. 1 and FIG. 2, the two nibs 31a, 31b of the nib component 3 each has a buckle element 35. In this embodiment, the buckle elements 35 are bumps arranged protruding out from the two sides of the two nibs 31a, 31b toward the center to buckle a buckle correspondence 21 of the feed component 2 in order to fix the nib component 3 to the feed component 2.

[0027] The omnibearing writable fountain pen according to the second embodiment of the present invention, as shown in FIG. 6, whose structure is generally the same as the omnibearing writable fountain pen of the first embodiment, and is different in that: the nib component 3 is a integrally formed structure in which the two nibs 31a, 31b are located at the front end of the nib component 3 and the buckle elements 35 are two bumps which fix the nib component 3 to the feed component 2.

[0028] The above description is only an explanation of the preferred embodiments of the present invention. One having ordinary skill in the art can make various modifications according to the above description and the claims defined below. However, those modifications shall still fall within the scope of the present invention.
