Fountain pen with a cuff pen

The innovation concerns a "fountain pen with a fixed on your conical inde of the fountain pen front part Cuff spring.

Until now it was common to use the clip nibs in fountain pens to be clamped between the ink feed and the inner bore of the front part of the filler holder, or when using Coil springs with a tubular shaft, the ink feed or comprise part of the ink guide from the spring shaft to leave in order to get a certain hold of the pen for the writing process.

It has already been suggested for fountain pens with concealed ink feed, screw an idant spring with a cuff-shaped shaft over the ink feed, or to slide it over the front of the fountain pen. These spring fastenings all have the disadvantage that they are cumbersome to manufacture and often too give the spring insufficient support.

The hiring has now set itself the task, one To create a fountain pen with a fountain pen front part that preferably covers the multi-part ink feed, in which a pen with a cuff-shaped shaft, a so-called cuff pen, directly and is therefore particularly firmly connected to the front part of the fountain pen.

This is achieved by the fact that the cuff pen, which is inside its cuff-shaped Shaft has several recesses, at the same time during the manufacture of the fountain pen front part in the plastic injection molding process is injected on the front part in such a way that the cuff holds so tight as a result of the recesses, as if it were made in one piece with the front part of the fountain pen, but the suspension properties of the front part of the nib are fully preserved. The recesses of the sleeve shaft of the pen can be arranged so that both on all sides limited openings, as well as slit-shaped ones that are open on one side Incisions are provided, which are distributed particularly effectively on the circumference of the cuff shaft. In this embodiment, the ink feed is designed in such a way that it can be pushed in from the rear, shaft-side The end of the fountain pen is possible and at the same time

a position fixation in the fountain pen front part, by appropriate flat, nose-shaped spreads on the ink feeder or groove-shaped recesses within the bore of the fountain pen front part., achieved

In the drawing are two different embodiments of the fountain pen according to the invention and then explained in more detail.

I ¹ Ig. 5 shows a cross section through the subject matter of the Pig. 4 according to the section line V - V,

Fig. 6 that of the Pig. 4 used cuff spring in a perspective view.

Pig's fountain pen. 1 and FIG. 2 consists of the fountain pen shaft, which is designed in the usual quiet manner, on which the fountain pen front part 1 is screwed. Injected into this fountain pen requirement part 1 is the pen 3, which encloses the conical end of the fountain pen front part 1 with its sleeve-shaped shaft. In order to achieve an intimate bond between the cuff pen 3 and the fountain pen front part 1, recesses 3 ^f and 3 ″ are provided in the cuff shaft of the pen 3, with one recess 3 'on the top of the nib 3 being enclosed on all sides, while the approximately opposite recess 3 "is designed in the form of a slot * that it remains open towards the tip of the nib. This particular design of the pen 3 is shown in FIG.

In the fountain pen front part 1 is the one from the ink supply part 4 and the concentrically arranged ring

Chamber part 2 existing ink feed inserted from the shaft end. The ink supply part 4 has the ink supply channels 5 and the ventilation channels 6 in the usual arrangement, and is widened at the tip-side end 4 'in the height direction, while it is kept correspondingly narrow in the lateral direction. The tip front part 1 has the same channel shape at the spring-side end, as a result of which the ink supply part 4 can be pushed into the pen holder front part ^{despite the widening of the head part 4 1.} At the same time, a twist-preventing bracket is achieved through this special shape. The ink collector 2 has ring-shaped ink chambers 2 in a known manner ^! The ink chamber part 2 is fastened in the fountain pen front part 1 in a known manner by means of the ring nut 7 * S ¹ .

The front part of the fountain pen according to FIGS. 4 and 5 is constructed in a similar way, only here the front part of the fountain pen 9 is up to just below the writing tip of the cuff nib 11 out, and the ink supply member 12, which

RA. 192 348 * 14.16if

the ink channel 13 ″ and the ventilation channel 14, is cylindrical in its entire length. That Ring chamber part 10 has the ink ring chambers in the usual way 10 'and the ventilation ducts 10 "and is held by the washer nut 15. The continuation of the ventilation channel 10 "up to the spring gap takes place in the Fountain pen front part 9 through the ventilation channel 9 '. In addition, the lower ventilation channel 16 is in the ink supply part 12 provided.

In this embodiment according to FIG. 6, the cuff spring is designed in such a way that the cuff is on the underside has a continuous longitudinal slot 11a and a trapezoidal incision lib on the top. In addition, two recesses lic are also provided on the side of the cuff part.

This design enables the cuff spring 11 to be injected into the front part 9 of the fountain pen but still the gate part that a possibly necessary Replacement of the cuff spring 11 can be made, since this can spring up laterally.
