Description

■ $. on one side of which a container for writing fluid is attached

; ä is on which a hollow handle shaft is placed and in the other

■ The other side has a pen tip holder inserted by means of static friction

or is screwed in.

In the case of fountain pens with tube and cleaning wire, users mainly use several devices with different line widths put into use. To remove the nib holder from the housing of individual fountain pens for cleaning or replacement being able to take out is usually a tool for example a key or a withdrawal sleeve required.

It is known to attach the nib support by means of a cone in a housing with a conical receiving hole in fountain pens with tubes. In order to do this without particularly soiling the operator's hands , a sleeve with an internal thread is used, with which the nib holder can also be pressed out of the housing and held during cleaning after it has been removed.

In writing implements of this type with writing tip support screwed into the housing, it is known to form key surfaces.

Using a small key, it is possible to unscrew the writing tip from the housing. The key must However, they have a certain size around the smallest size to offer an effective attack surface for twisting even a heavily encrusted writing implement.

In the case of auxiliary tools of this type, which must be kept separately, there is a risk of getting lost. In addition, these parts are required in addition to the disposable writing instrument.

The innovation is therefore based on the task of all Use of the writing instrument to be able to safely perform the necessary disassembly and assembly work without additional aids. Soiling of the operator's hands should also be largely eliminated.

This object is achieved according to the invention in that a thread matching the pen housing is formed on one side in the interior of a hollow handle shaft, while on the other End the inside of the grip shaft to the tip holder. Purpose of the transmission of a torque and / or a tensile force is adapted.

As can be seen from the figures, the fountain pen according to the invention consists of a fountain pen housing 1 on which a container for the writing fluid 2 is attached .

Another threaded collar 5 is used to accommodate the not shown

Protective cap. In addition, there is a conical bore 0 in the housing 1

arranged, which serves to receive the nib support 7, the

U has a tube 8. A thread 9 is in a known manner on Nib support 7 is provided to remove it from the housing of the Fountain pen 1 to draw.

The hollow> handle shaft 4 is designed so that at one end in the. A thread 10 is formed inside, which ends in a conical mouthpiece 11. To match this mouthpiece 11, a conical surface 12 is seen on the pen housing 1 in front of. On the opposite side of the handle shaft 4 there is a further internal thread 13 which fits & .of the threaded projection 3 of the pen housing 1. By means of a suitable shape or color design of the handle shaft 4 , it is possible to connect this unmistakably at the right place with the pen housing 1 zn.

In order to remove the nib support 7 from the pen housing with the fountain pen according to the invention, only the handle shaft 4 has to be separated from the preferably multi-thread tz 3

It is then possible to use the handle shaft 4 as an auxiliary tool Use 1 xu to pull the nib holder 7 out of the housing. In order to ensure that the hollow, thin-walled handle shaft 4 rests securely on the pen housing 1 reach, this is provided with a conical surface 12 and the handle shaft 4 has a mouthpiece 11 on.

It is also possible to use the handle shaft 4 as an auxiliary tool

See below for FiÖleehpeibem with a nib holder ΐ screwed into the housing 1. For this purpose, key surfaces are only required on the nib support 7 in a known manner and corresponding mating surfaces in the hollow handle shaft 4 instead of the thread 10.

The object of the innovation makes it possible to remove the nib holder from the pen housing without additional tools. It is therefore not a fool's writer To supply auxiliary tools, and there is also no additional work, since the grip shaft 4 and the container 2 have to be removed in a known manner to fill up the writing fluid are.
