Abstract

The writing implement, esp. propelling pencil, has an outer casing, an inner transport mechanism, a storage container for pencil leads, etc, and an outer operating device for the mechanism. The device (8) is located in the front holding area (4) of the pencil (1). It consists of a slide or similar, which is connected to the mechanism (12), and the lead container (11). The slide has a profile (14), complementary to a finger tip.

Description

The invention relates to a pen traceable writing lead, especially a print pencil with an outer case body and one transport mechanism located therein as well as given if a storage container for pencil leads or the like and an external actuator for this transport mechanism.

With such mechanical pencils it is from time to time required to wear the writing lead after to transport. This is done by one or more pressing down on the back of the Stylus located push button. It is for that required the pen regarding the hold able to implement, the write-stop position - usually with three fingers - be changed must and the pen held with four fingers while the thumb presses the push button. On then the pen must be in writing again position to be implemented.

This is cumbersome and also comparatively time elaborate, which is especially in a hurry low fonts - dictation, journalistic notes and with  writings, etc. - adversely affects. This disadvantage expresses u. a. also in the fact that some users for pressing the push button as an emergency solution "Head" and your forehead help, but what basically just an alternative solution due to the represents predetermined actuation design.

The object of the present invention is to be operation of a pen of the type mentioned Way to simplify and in particular hand to facilitate and the necessary to operate shorten overall time.

To solve this problem, according to the invention particularly suggested that an actuator in front holding area of the mechanical pencil provided is.

By this arrangement of the actuator in the hold area of the pen is a cumbersome environment no longer required. The subsequent transport the writing lead can be practically uninterrupted here be made during the writing process.

The actuator is expediently essential lichen by one with the transport mechanics or the same related actuating slide or the like.

As a result, the pen can still be firmly locked will hold because the pressurization also when operating and moving the operating slide can be maintained.

It is particularly easy when the operating slide or the like at the lower end of the with  Transport mechanics in operating connection Mine storage container is connected to this. This can be done with the usual pen designs tions well and with comparatively little effort realize.

An embodiment of the invention provides that the loading actuation slider approximately the shape of a fingertip has complementarily adapted profiling, in particular an indentation with one of the pen tip turned bead.

This is a cheap thumb or possibly pointing finger rest formed, on the one hand favorable for the Hold the stylus and that when pressed the slider prevents slipping.

If necessary, there is a sliding guide for the actuator supply slide provided at an angle to the longitudinal axis of the pen runs, in particular at an acute angle approximately in adaptation to a downward pivoting movement of the Hold your thumb.

The direction of actuation for the slide thus gives way on the axial direction of the pen and thus also from the essentially axial direction of the slide pressurization when pressure is applied to the writing tip. This can result in unwanted incorrect actuation of the slide to be avoided because they deviate from the axial direction an oblique sliding or swiveling movement for loading is required.

Additional embodiments of the invention are in the further subclaims listed. Below is the invention with its essential details based on of the drawings explained in more detail.

It shows  

Fig. 1 is a side view of a writing pen,

Fig. 2 a z. T. in longitudinal section side view of the front holding area of a pen,

Fig. 3 is a partial side view of a pen in the front area with an oblique operating slide and

Fig. 4 is a view corresponding approximately to Fig. 3, but here with indicated holding fingers.

Fig. 1 shows a mechanical pencil 1 having an outer housing body 2, at the front, the writing tip 3 facing the end of the holding portion 4 is located. The pen is held in this holding area, being held between the middle finger 5 , index finger 6 and thumb 7 .

In this front holding area 4 , an actuator is now provided, which is designed as an actuating slide 8 . In the exemplary embodiment shown in FIG. 1, this actuating slide 8 is additionally to the actuating pushbutton provided at the rear end, as was previously also provided on printing pencils.

Fig. 2 shows the internal structure of such a lead pencil 1 can be seen. Within the tubular housing body 2 is located in its longitudinal cavity 10, then a push button 9 to a reservoir 11 for pencil leads, to which a writing mechanism 12 connects to the writing tip towards the holding area 4 . A return spring 13 can also be seen in the transition area between the storage container 11 and the transport mechanism 12 .

The actuating slide 8 is connected in this embodiment, for example, to the reservoir 11 . Optionally, the reservoir 11 , which carries the actuation movement to the transport mechanism 12 via, can be moved longitudinally with the aid of the push button 9 or by means of the actuating slide 8 for tracking the writing. After releasing the actuating slide 8 or after a corresponding relief, this automatically returns to the starting position shown in FIG. 2. The refill of the writing lead can thus be carried out in the writing position and almost without interrupting the writing process. Annoying moving the stop position of the mechanical pencil can be eliminated. Nevertheless, for the user in the embodiment shown in FIG. 1 there is still the possibility of actuation via the pushbutton 9 , so that an order of the previous actuation habits is also possible without problems.

As can be seen in Fig. 2, the outside of the actuating slide 8 is profiled, this here having an indentation 14 for supporting the pointing finger or the thumb and a bead 15 adjoining the writing tip. This provides a good finger rest and also prevents the actuating finger from slipping when the actuating slide 8 is advanced.

In the exemplary embodiment according to FIGS. 1 and 2, the actuating slide 8 runs approximately axially parallel to the mechanical pencil 1 in the direction of displacement. FIGS. 3 and 4 show in deviation to an actuating slide 8 a, the somewhat obliquely disposed in the displacement direction. Since an inadvertent actuation of the actuating slide 8 is avoided even with stronger axial pressurization when pressing strongly with the stylus. In order to actuate it, an oblique sliding or pivoting movement is required here, in deviation from the axially parallel longitudinal direction, as indicated by the arrow Pf 1 in FIG. 4. This movement corresponds to actuation with the thumb 7 , rather the "anatomy", since the finger does not perform an exact linear movement, but rather a swiveling movement around the rear thumb joint.

The connection of the actuating slide 8 or 8 a can be seen depending on the internal structure of the mechanical pencil, whereby in the embodiment according to FIGS. 3 and 4 the inclined movement of the actuating slide relative to the axis-parallel movement of the reservoir 11 or the transport mechanism 12 is taken into account can be.

In Fig. 2 it is indicated that the actuating slide 8 with the aid of locking, attached to the actuating slide 8 small push buttons in corresponding recesses from the reservoir 11 can be clipped.

It should also be mentioned that the actuating slide 8 or 8 a can also be provided on its own without an additional push button 9 at the rear end of the mechanical pencil 1 .
