Adapter for pens and pens

The invention relates to a working and auxiliary means for adapting writing and drawing pens to the writing hand. Additional functions: erasing, tip and heat protection.

For drawing and writing pens, especially those with circular or Hexagonal cross-section results in a relair .- / small in writing position Grip and pressure surface between thumb and fingers. The holding beltd typing pressure forces therefore create unpleasant furrows (scribes' dents), especially on the uppermost part of the middle finger.

There are pens known (Rotring, ballpoint pen), the cross-section of which a Triangle with curved sides is similar, so that the pens on the handle parts adapt to the anatomical triangle that is in the writing position is made up of down, index and middle fingers. The surface pressure between pen and fingers can thus be reduced.

With the now frequently used pressure pens with steel or metal surfaces This creates rapid heat dissipation from the skin and a deposit of sweat on the grip areas. This makes the pen slip more easily and a higher holding pressure must be applied. For this reason, ring corrugations (e.g. PENTEL-GRAPH) are used in some brands. or straight cross-corrugation pressed in, but this leads to increased stress the skin.

Thin lead pens (e.g. 0.5 TK pen, Faber-Castel) usually have less than the Feed print head in combination with the cleaning needle a small eraser, which, however, due to its small dimensions, has been used up after almost seven lines of etching and can only be viewed as a weak makeshift because the needle will appear after a short time. and on the paper scratches.

Another disadvantage, especially of the thin lead pencils, is the up to five Thin guide sleeve protruding a millimeter, which when inserted into pockets of clothing May cause damage or marks by the mine. Push-on sleeves are available as a remedy, but when using the Plugged in or separated from the pen and cannot be found.

The invention wants to remedy the disadvantages mentioned and has to Task set:

1) An adapter for the usual writing and drawing pens to create at the same time

2) provides thermal insulation between the skin and the pen,

3) Can be held in the hand with a minimum of holding force can,

4) can be used as an eraser and

5) cover securely just by sliding the tip of a pen.

According to the invention, the object is explained as follows and in the drawing shown:

Fig. 1 shows the thick-walled tube (1) of the adapter in perspective Illustration, attached to a pressure pin (3). Including the corresponding height sections A-A, B-B and C-C without a pin, Fig.2 the tube (1) in half section with inserted slide rail (2), Fig.3 the possible shape of a slide rail (2) with punched and bent retaining pins (2.1).

On the thick-walled tube (1) there are three inclined, cross-corrugated grip points (1.1) - of which the foremost is visible - each at an angle about 60 ° for the thumb, index and middle finger. Internally of the tube three sliding pieces (2) nestle against the inner wall and become fixed in place by small retaining pins (2.1). The bore of the tube (1) is in the lower part corresponding to the tip of the cone a pressure pin is smaller, so that a kind of hollow truncated cone (1.2) forms which limits the depth of insertion of the pressure pin (3).

The outer shape of the adapter with the three corrugated grip points thus fits into the geometric shape formed by the fingers and thumb and thus enables fatigue-free and pressure-free writing and drawing. When making the tube (1) from eraser rubber or plastic the surface pressure is reduced even further and the heat insulation restricts the secretion of perspiration. The simple advance of the Adapter over the tip of the pen, it is disarmed and the lead case is protected.
