Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small tube type writing instrument for writing with writing liquid, a slitted writing tip type writing instrument, a felt tip type writing instrument, etc., which is included in an automatic drafting and writing instrument, a coordinate type writing instrument, or a plotter. This invention relates to a device for sealing the tip of a writing device to prevent writing liquid from drying out when writing is interrupted.

For example, German Patent Application No. 2724855
No. 3104962, 1-27 (Publication No. 198)
(August 12, 2013) Automatic drafting machines having wheels or rollers, carrying a controllable writing device, and having a carriage movable over a writing surface, as well as monochromatic or multicolored In the case of Zorotsuta, coordinate type writing instruments, etc., it is necessary to dry the writing liquid on the writing surface as quickly as possible so that what is written is not rubbed off.
Despite this, when writing is interrupted, the writing fluid on the writing tip and, by extension, on its end surface is kept from drying out so that writing can be resumed at any time (there is an unresolvable contradiction between this and the necessity).

In hand-held writing instruments such as ink-type fountain pens from companies such as Co., Ltd., the above-mentioned problem is being solved by so-called small-tube pens, i.e., an ink guide tube filled with a thin wire weighted by a falling weight. is used, the wire protruding from the end face of the corresponding small tube, so that the ink film that may be present is broken at the beginning of writing, i.e. the wire tip and the guide tube rest on the writing surface. When it is written, its writing ability is instantly regenerated.

The above method is effective when the writing interruption is short or when using a hand-held writing instrument, because the obstruction to the start of writing that occurs in such cases can be avoided by, for example, shaking the writing instrument for a long time to remove the inside of the canal. It can be removed by moving the drop weight wire, or it can also be solved by repeatedly moving the writing tip back and forth over the writing surface at the beginning of writing until the writing fluid flows out. You can also start writing with a slit pen in the same way.

The above-mentioned well-known problem with automatic writing devices such as Riber is that when it is visually confirmed that the writing fluid is not flowing, the first drawing automatically written from the writing device is traced with that writing device. A solution is being attempted. The disadvantage of this method is that you have to start writing many times (
Again, although the method calls for caution and, in some cases, requires the intervention of the scribe and special instrumentation, the movement of the ink stream is no longer reliable. Furthermore, if there is a long interruption in writing, the writing tip will become extremely dry, thus requiring a lengthy cleaning of the writing instrument after it has been removed from the writing instrument, i.e. an interruption of the work. be done.

An object of the present invention is to provide a mechanically operated writing instrument that can absolutely reliably start writing with the writing tip on the writing surface even in the case of extremely fast-drying writing liquid or writing liquid with a high pigment content. It is.

According to the invention, this problem can be solved by providing a device for sealing:
a seating device arranged at a suitable point on the instrument outside the writing area for receiving the writing tip after the writing interruption exceeds a predetermined length;
This solution is achieved by designing a seat plate or a receiving surface, which seals the inlet cross section of the writing tip, or a conical receiving slit or the like. Advantageous embodiments of the invention are shown in claim 2.

According to the present invention, immediately after the end of writing, or after the end of the writing interruption when the writing interruption exceeds a predetermined length, the writing tip is placed at an appropriate location on the instrument by means of a guide member for the writing tip. is pressed onto a seat plate made of a soft elastic material, for example rubber or soft PVC. This plate is still wetted by the writing fluid, and if the writing interruption is prolonged, the writing fluid that has flowed out around the canalicular opening or slit opening is also allowed to dry, but immediately after the writing tip is released from the seating plate. A dry residue of writing fluid is left on the plate so that the writing tip is completely ready for use and no errors occur during the first draft.

The process described above can be repeated over several hours depending on the pigment and fixing agent content of the writing fluid. Also, if dried ink residue builds up, the seating plate can be easily cleaned with a wet cloth or replaced with a new plate since the cost of the plate is negligible.

The idea underlying the invention is to prevent the drying of the writing fluid at the writing tip by sealing off the dangerous inlet cross-section, which is adapted to the structure and mode of operation of the writing instrument in each case. It is possible to use various implementation shapes by making it possible.

If the invention is to be used in rank-guided instruments, for example in patent application no. If, in addition to the writing tip, dryness of other parts of the writing instrument in the vicinity of the tip endangers its function, it is advantageous to place the writing tip in a saucer-shaped soft elastic member. It is also conceivable to run the writing tip into a turnable slit or the like.

The advantage of ensuring the start and continue functions in mechanically guided automatic writing instruments by means of seals is that
This is not particularly evident only in the case of ordinary writing tasks, where the symbol to be written is entered via a keyboard and immediately output by a writing instrument, but especially text or symbols stored electronically in the instrument. It is also useful when writing down. Such text can be many lines, memorized symbols, several centimeters long, and can be written at speeds of up to 10% per second.
It can be done with a writing speed of value 0u. In this case, when in doubt, a writing instrument that becomes completely dry and completely unable to write is
This poses only a lesser disturbance than a writing device which starts writing by being dragged somewhere along the writing sequence of the symbol sequence or drawing sequence to be written. It goes without saying that the last-mentioned situation is particularly unpleasant; for example, ink overflowing results in extremely unclear drawings.

The invention will now be explained with reference to the illustrated embodiment.

FIG. 1 shows a writing instrument according to Patent Application No. 3104962.1-27, comprising a carriage having wheels or rollers, holding a controllable writing device, and capable of running on a writing surface. The sealing device according to the present invention is provided on a wheel provided with teeth so that the toothed wheel meshes with a ruler with a rack placed on a writing surface.

A writing instrument l on a ruler with a rack 2 holds a writing tip 7 in its writing instrument holder 3. When the writing interruption time exceeds a predetermined length, the end 7 of the writing instrument is removed from the writing range 5 and placed on the seating device 4 disposed on the ruler 20 portion 6 with a rack. Ru.

In another embodiment of the present invention, the entire portion 6 of the racked ruler 2 may be covered with a suitable soft elastic material, on which the tip 7 of the writing instrument 1 may be seated. Furthermore, the object of the present invention can also be achieved by providing a conical slit in the soft elastic saucer or the soft elastic molded member outside the writing area 5 and within the travel range within which the writing instrument l can reach. it is obvious.

In the so-called "Zorotsuta" 9 shown in FIG.
The writing tip 7 is arranged to receive a writing tip 7 which is not used for writing at that time. The writing tip 7 is thus mounted or inserted into the holding device 8 until it is needed for writing again.
