Definitions

• the technical solution relates to a fountain pen comprising a stylus set with the stylus and ink container, a stylus set case and a cap.
• the projection gradually wears out, the connection ceases to be strong, and usually loosens over time.
• Another variant is the friction connection of the cap to the body of the pen, which, however, generally damages its surface at the points of the friction surfaces.
• the pen stylus caps are not necessary for pen writing and they are often discarded by users thoughtlessly, while being often lacked when writing is finished. Therefore, it is preferable to slide the stylus cap on the opposite end of the pen body, which however changes the ergonomics of writing.
• the base of the technical solution of a fountain pen consisting of the stylus set with the stylus, an ink container, pen stylus set housing and a cap is an arrangement in which a spacer tube with an ink cartridge inside is connected to the stylus set housing, closed at the opposite end with a stopper, while all the inner parts of the fountain pen are slidably mounted in the pen housing provided with an inner magnetic ring and a fixing ring at the end facing the stylus set.
• the pen housing is terminated by a hollow fixing screw provided with an internal magnetic ring.
• the pen cap is formed by a tube the outer diameter if which is determined by the sliding placement in the magnetic ring of the pen housing and in the fixation ring and the inner diameter of the cap tube is determined by the outer dimension of the pen stylus around which the cap is freely and slidably mounted in the pen housing.
• the extreme positions are defined by the fixing ring inside the pen housing and the cap in the position inserted into the hollow fixing screw, that is to say with the pen stylus extended and the annular hollow fixing screw on the spacer tube and cap inserted into the pen housing on the side equipped with the magnetic ring and fixing ring, with the pen stylus retracted.
• the extended part of the cap has an identical outer profile with the outer profile of the fountain pen housing.
• the fountain pen is supplemented with a hous- ing with a through hole, not shown in the figures, provided with a magnet at one end which interacts with the magnetic ring of the hollow fixing screw or the magnetic ring of the cap to fix the position of the pen inserted in the housing.
• Fig. 1 is a perspective view of the fountain pen components
• Fig. 2 is a side elevational view of the fountain pen when being closed
• Fig. 3 shows a partial enlarged longitudinal section of the fountain pen when being closed, with the ink cartridge
• Fig. 4 shows a side view of the fountain pen in the ready-for-writing state
• Fig. 5. shows a partial enlarged longitudinal section of the fountain pen in the ready-for-writing state, with the ink converter.
• the slim cylindrical shape of the entire fountain pen including the cap 6 is evident.
• the fountain pen comprises, on the one hand, the known components, namely the stylus set 1 fitted with a writing stylus 11 and an ink reservoir in the form of an ink cartridge 12. All the other parts of the fountain pen are new.
• the stylus set 1 shell 2 has a fitting on the side adjacent to the ink cartridge 12 on which the spacer tube 3 is mounted; the opposite end of the tube is tightly closed by a plug 31-
• the connection of the spacer tube 3 with the plug 31 may possibly be detachable, but this is not a production or user friendly embodiment.
• the part of the cylindrical plug 31 that extends beyond the end of the spacer tube 3 has a fitting on an outside diameter that is smaller than the inner diameter of the spacer tube 3. On this fitting of the plug 31 the hollow fixing screw 4 is slidably mounted with its inner hole.
• a thread with parameters corresponding to an inner thread in the edge of the housing 5, consisting of a tube with inner diameter bigger than the outer diameter of the distance tube 3.
• the screw connection of the hollow fixing screw 4 to the housing 5 can be replaced by another, known detachable connection, but in terms of pen design according to the technical solution it will not be more advantageous.
• a magnetic ring 41 is mounted in the inner fitting, with its inner diameter corresponding to the sliding fit on the fixed part of the hollow fixing screw 4.
• the housing 5 there are slidably placed the distance tubes 3 with the ink cartridge 12 inside and the tube 3 continuously adjoining shell 2 of the stylus set 1, inside with the stylus set 1 provided with the writing stylus 11
• the housing 5 is provided at its end adjacent to the writing stylus H with a magnetic ring 51 fixed by the fixing ring 52, adjacent to it from the inside of the housing 5.
• the inner diameters of the magnetic ring 51 and the fixing ring 52 are identical and the writing stylus 11 is slidably mounted therein with some clearance.
• the cap 6 is formed by a tube with its outer diameter determined by the sliding fit in both the magnetic ring 51 and the fixing ring 52 of the housing 5.
• the inner diameter of the cap 6 tube is determined by the outer dimension of the pen stylus 11, around which the cap 6 is freely and slidably mounted in the housing 5 of the fountain pen.
• a cylindrical fitting At the op- posite end of the cap 6 there is a cylindrical fitting, the outer diameter of which corres- ponds to the outer diameter of the pen housing 5 and also the outer diameter of the hollow fixing screw 4.
• the magnetic ring 61 In this part of the cap 6, extended by the fitting, on the side of the annulus adjacent to the tube part of smaller diameter, there is fixed the magnetic ring 61.
• the magnetic ring 51 of the housing 5 interacts with the magnetic ring 61 of the cap 6.
• the cap 6 covers and protects the writing stylus H of the pen, it fixes the po- sition of the inner slidable parts of the pen and forms the end of the continuous cyl- indrical shape of the closed pen.
• the part of the cap 6 enlarged with the fitting may have an outer diameter different than the outer diameter of the fountain pen housing 5.
• the outer shape of the enlarged part of the cap 6 may be arbitrary, for example spherical.
• the ink converter 13 may be replaced by other known ink filling solutions, such as piston filling or obsolete dropper filling.
• the shell 2 of the stylus set 1 is detachably connected to the stylus set 1 and it has a fitting on the side adjacent to the ink converter 13 on which a spacer tube 3 is slipped on with its inner diameter; it is formed by a tube the opposite end of which is firmly closed by a stopper 31-
• the connection of the spacer tube 3 with the plug 31 may optionally be detachable, but it is neither a user nor a production advantageous embodiment.
• the part of the cylindrical plug 31 that extends beyond the end of the spacer tube 3 has a fit- ting to an outside diameter that is smaller than the inner diameter of the spacer tube 3.
• the hollow fixing screw 4 is slidably mounted with its inner hole.
• the outer surface of the screw is provided with an external thread having a dimen- sion corresponding to the internal thread in the housing 5.
• the fixing screw 4 is connected to the internal thread of the housing 5, which is formed by a tube.
• This screw connection can be replaced by another, known, detachable connection, but it will not be more advantageous from the point of view of the con- struction of the fountain pen according to the invention.
• a magnetic ring 41 On the side opposite to the thread, inside the annulus of the hollow fixing screw 4, a magnetic ring 41, the inner diameter of which is equal to the inner diameter of the hole in the hollow fixing screw 4, is fixed in the inner fitting.
• the fountain pen housing 5 is at the end adjacent to the writing stylus 11 , inside and immediately at its edge, provided with a magnetic ring 51 fixed by a fixing ring 52 adjacent to it from the inside of the housing 5.
• the lid 6 is formed by a tube the outer diameter of which is de- termined by the sliding fitting in the magnetic rings 41 and 51 of the hollow fixing screw 4 and the housing 5 of the pen and also in the fixing ring 52.
• a cylindrical fitting is formed, the outer diameter of which corresponds to both the outer diameter of the housing 5 and the outer diameter of the hollow fixing screw 4.
• the magnetic ring 61 of the lid 6 In this part of the lid 6 enlarged by the fitting, on the annulus side adjacent to the tube part of smaller diameter, there is fixed the magnetic ring 61 of the lid 6.
• the tubular part of the cap 6 In the writing position of the pen, shown in figures 4 and 5, the tubular part of the cap 6 is inserted into the hollow fixing screw 4 on the side of the pen housing 5 opposite to the stylus set 1. In this position of the cap 6, the magnetic ring 41 and the magnetic ring 6 ⁇ of the cap 6 interact.
• the lid 6 fixes the position of the inner slidably placed parts of the pen, including the stylus set 1 of the pen, in a position when the writing stylus 1 ⁇ of the pen is extended from the housing 5. Simultaneously, the lid 6 makes the end of the continuous cylindrical shape of the pen in the writing position and its fitted part adjoins the fixation hollow screw 4 and forms a continuous cylindrical surface together with it and with the housing 5 of the pen.
• connection of the cap 6 is secured in both functional positions, both for pen writing and for writing stylus H protection and to prevent ink from drying out, by magnetic rings 41. 51 and 61. These are preferably made of neodymium magnets that are not subject to atmospheric impacts and they create sufficient holding force required for the correct functioning of the fountain pen in both operating positions of the cap 6.
• the visible part of the hollow fixing screw 4 connected to the housing 5 is substantially identical in shape to the visible part of the lid 6, it is advantageous to distinguish these components in their particular embodiment by colour and / or surface treatment and / or materials used.
• Well-known clips for attaching and fixing the pen according to the owner's preference and preference, for example in a garment, can be attached to the fountain pen housing 5 according to the invention.
• the cylindrical slim shape of the fountain pen allows it to be inserted into a protective and / or decorative tubular shape case, not shown in the figures, preferably closed at one end by a magnet.
• This in interaction with the magnetic ring 41 of the hollow screw 4 respectively the magnetic ring 61 of the cap 6, fixes the position of the pen in the housing without any need to close the other side of the housing and it accelerates the removal of the fountain pen from the protective and / or decorative tubular housing.
• the fountain pen housing 5 is made of a slim, non-round profile with a longitudinal cylindrical bore inside, wherein the cap 6 extension and the hollow screw 4 have the same outer profile as the outer profile of the housing 5.
• the cap 6 extension may have a different external profile than the fountain pen housing 5 and the hollow screw 4, which facilitates distinguishing the cap 6 from the other components of the fountain pen.
• the pen according to the technical solution is suitable for industrial use and mass production, changing long-term stable and unchangeable construction of fountain pens.
