FILLING DEVICE FOR FILLER

The invention relates to an ink filling device for a fountain pen, " which is intended for use with ink cartridges and whose passage of the spring holding portion is so formed is that it cooperates with an ink cartridge.

More and more cartridge fills are used that consist of a front part or section for supporting the spring and a body or shaft which is detached from the front part and attached to it can be attached with the ink contained in a cartridge which is inserted into the rear end of the section, whereby it empties, and the fountain pen is given its ready-to-write shape by the fact that the barrel is reattached in place will.

209849/0665

When the ink in a cartridge is used up, the shaft of the Section removed, the empty cartridge removed and replaced with a full one, the barrel reattached, thereby replacing the fountain pen is ready to use.

If the ink in a cartridge has run out and the cartridge is not full more is available, then the fountain pen as such can no longer be used to be used.

An object of the invention is to provide a device that does in connection with such a fountain pen allows this to be used as long as ink is available from a bottle.

The device according to the invention therefore makes it possible to use a fountain pen to create, which at the same time has the advantages of the cartridge fountain pen and the piston fountain pen and thus practically always is ready to write, as in most cases a bottle of ink is available.

The device according to the invention is characterized in that it has an ink chamber which can be accommodated in the body of the fountain pen and at one end has connection means which to the passage of the fountain pen section are tight, as well as means for sucking ink into the ink space from a bottle into which the spring of the section has been immersed, as is usual with a conventional piston fountain pen.

The following description, by way of example, relates to the attached drawing:

Figure 1 is a partial view in longitudinal section of an embodiment the device according to the invention,

209849/0 665

Figure 2 shows the same item as Figure 1-, but in a different way Position,

FIG. 3 is a top view of the device according to the invention in FIG Position according to FIG. 2 and is around 90 compared to this figure rotated, and

Figure 4 is a fragmentary view, on a smaller scale, of one incorporating that of the present invention Device provided fountain pen.

The device according to the invention consists of a cylindrical Body 11, which is preferably made of clear plastic and the front end of which consists of a connection 12 which, on the front end wall 13, has an input 14 with a frustoconical bore 15, which is extended by a cylindrical bore 16 and is designed to cooperate with the end of a passage C of the section S, the other end in connection with the pen P is (Figure 4). Inside the bore 17 of the body 11 is a displaceable piston 18 is arranged, on the shaft 19 of which a Lever 21 is pivotally mounted about "a pin 20; the lever is long enough to be around its preferably curved extension 22 over the protruding rear edge 23 of the body when the piston 1Θ at the front end of the bore 17 is located.

To use the device in the absence of an ink cartridge, the The body or shaft F of the fountain pen is removed from the section S in the manner that is usually done to insert a cartridge, and after dismantling, the device according to the invention is used in place of the cartridge in the same way as a cartridge, by inserting its front end so that the entrance

cooperates with the end of the passage of the fountain pen section. the The position then corresponds to that shown in FIG.

The assembly formed by the section and the device according to the invention is dipped into an ink glass and the piston 18 [FIG. 2) is moved backwards by pulling on the lever 21 in the direction of the arrow _f: with the same effect as with a syringe, ink is drawn into the chamber 24 sucked in until it is filled. Upon completion of the
Movement (Figure 2) is the pin 20 outside the body 11, so that it is possible by pivoting the lever 21 about this pin to fold the lever along the body 11 (Figures 2 and 3) on which it rests, without one to form substantial projection while the wings 25 and 26 of the end 22 encompass the body 11 and the
Hold lever 21 resiliently on the body. The shaft F of the fountain pen is reattached in the usual manner by being attached to the section S, and the user has a filled fountain pen which does the same service to him as one with a cartridge
filled holder.

This process can be repeated as long as the user does not have any
Has ink cartridge, the lever 21 initially by rotating it
erecting the pin 20 after separating the end 22 from the body 11; then this end is actuated with the ^c ingern.

Claims (6)

Claims 1.) Ink filling device for a fountain pen for use with Ink cartridge is provided and the passage of the spring holding portion thereof is formed to be connected to an ink cartridge cooperates, characterized in that it has an ink space which can be accommodated in the body of the fountain pen can and has connection means at one end which are sealed to the passage of the section, as well as means for sucking ink into the ink chamber from a bottle into which the nib of the section has been dipped, as is the case with a conventional piston fountain pen is common. 2. Filling device according to claim 1, characterized in that the Ink chamber is a cylindrical body inside which a piston can move. 3. Apparatus according to claim 2, characterized in that on the Piston an actuator is attached. 4. Apparatus according to claim 3, characterized in that the actuating member can be folded along the ink space. 5. Apparatus according to claim 4, characterized in that the actuating member is a lever which, at the end opposite that serving for its rotatable mounting on the piston is, expires in resilient wings, which are designed to encompass the body of the ink chamber to hold the lever in place, as long as it is not actuated. - 5 - 209849/0665 6. Fountain pens, designed for use with ink cartridges and provided with a device according to any one of the preceding claims. :> ο <i 8 4 9/0 6 6 B
