Description

Writing implement, in particular a filling pencil or pen holder, with a conical tip and the fingers adapted contact surfaces on the Grigschaft Die The invention relates to a writing instrument, in particular a filling pencil or pen holder, with a conical tip and finger-adapted contact surfaces on the handle shaft.

The new feature of the invention is that the handle shaft immediately behind the tip in a ring part with a shaft diameter the same diameter, to which a finger shape adapted, passes through a constriction-formed section adjoins, wherein the ring part and the constriction part either angular or longitudinally or transversely grooved and the tip, the ring part and Constriction part has a uniform body that is exchangeably attached to the shaft represent. Another of one can advantageously be attached to the constriction part Connect the ring and a constriction part of the existing section. The lace, Ring and constriction parts expediently form interchangeable pieces.

This design of a writing instrument is based on the following considerations.

If you start with a common wooden pencil, it is obvious that that its working side is moved back more and more by the constant sharpening. It is therefore not possible to give a wooden pencil a cheap grip because this handle shaft is sharpened.

The usual filling pencil, the shape of which is your pencil Has a similar education is i-. its grip shape cannot be changed. The writing purpose accordingly, as shown below, the shape of the handle must be changeable. That's why the usual filling pencil handle also has disadvantages. In no way are these writing implements adapted to the particular hand of the writer and their posture, some of which are is sometimes exercised with curved fingers and even with certain writing or Drawing work with one and the same user of the device is sometimes different can be.

If you want to draw lines that are close to each other, the exact course should have, then the writing instrument is briefly touched, with the fingers if possible tight. on the working side. If you want to hatch, then the writing instrument becomes held very long in order to handle the broad side of the working side as much as possible. Neither - on the personal character nor on the peculiarity of the attitude regarding short, fine or long, coarse strokes have been given sufficient consideration up to now.

You already have on the wooden pencil or the barrel of the pen holder Sleeves pushed on, the purpose of which is to tighten the pencil or shaft and more secure to hold. The sleeves thicken the side of the hand in one place and disturb their proportion. What was left out of consideration, however, is the corresponding one Adjustment of the cone tips. The shape and length of the cone influence, however just the most effective writing position of the hand. It is already the suggestion made "order to work certain grip points into the shaft. With the peculiar and especially extraordinarily different kind of posture of the writing implements, however, it is not possible with such incorporation of the possibility of handling for increasing the number of writers, it is only suitable for one limited circle of them. Such writing tools are special devices. A but as simple an object as a pen or pen holder must be a general device be.

In order to be able to hold a writing instrument correctly, the distance must be the Finger from the working side can be changed in each case, then the writing instrument easily and securely pressed into the hand, making it easy to hold.

This is supported by the invention through the interchangeable arrangement of the particularly shaped handle parts lined up and corresponding to the shaft thickness, whereby a more favorable handling is achieved for the fingers.

With reference to the drawing, the subject matter of the invention is intended in some exemplary embodiments are explained in more detail.

On the shaft there are constrictions c for the holding fingers (thumb and middle finger) and supports, e.g. Ring pieces b, the diameter of the ring piece being equal to the diameter of the shaft. The ring part b adjoins the tip a , which, like the first support retainer b, c, can be removed so that it can be exchanged for parts of different length (tips Fig. 1 to 8; first support retainer Fig. 9 to 12) can be seen in Fig. 17. -The interchangeability of the tip means that the same pencil can be used for the same user in short or long-term use, depending on whether he has to carry out small or large-scale work. .

Figs. 1, 5, 9, 13 show threaded pins at the tip a and threaded holes on the first support retainer b, c, which in turn is threaded with the second Auflagelialtestück d. e is connected, so that a writing instrument of the example Execution arises. like this in A bb. 1S is illustrated.

Since the shaft in its strength directly for the adaptability the respective hand (finger) dimension and position must be established, it is It is important that the cone serving as a mine guide or spring clip on the base has a diameter equal to that of the shaft. Therefore corresponds to angular Shank the diameter of the cone of the diagonal of the polygon.

Incidentally, the interchangeability of the shaft parts also simplifies the Storage of writing implements to a considerable extent.

Because the writer must be able to have the device in his hand squeeze in so he can hold it properly, which a smooth cone won't do is, according to the invention, the tip cone is provided with transverse grooves or transverse depressions, which allow a strong grip. (Fig. 2 and 6).

Figs. 3, q., 7, 8 show a cone with longitudinal grooves and angularity of the same for the purpose described above and Figs. 11 and 12 show the same design of the first support retaining piece with the cross-sections V-bV (Fig. 14) and XY (Fig. 15).

The unscrewable cone also enables metal lead clamp chucks to be inserted into it to be provided with different clearances, so that thin writing leads or thick colored leads can be used.
