Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a writing instrument having an operating member which can be operated without essentially changing the entire position of the writing instrument in the hand.

DE 1020256 A1 discloses a hand-held writing instrument with a lead that is actuated by lateral pressure on the transversely elastic part of the writing instrument 1III. In this case, the shaft and the clip are integrally formed. Manipulation of the lead takes place without essentially changing the overall position of the writing instrument in the hand.

However, the inner knock mechanism for operating the lead (D is significantly different from the normal knock mechanism in ballpoint pens).

It is technically difficult to manufacture the inner wall knock part precisely to fit the conical part, and when used for a long period of time, the friction between the two conical surfaces may cause trouble when operating a hand-held writing instrument.

It is therefore an object of the present invention to provide a writing instrument which is easy to assemble and which has an entire upper shank end which is significantly tapered by shaping, such as is used in many cases which essentially change the position of the writing instrument in the hand. An object of the present invention is to provide an operating member for the well-known knocking mechanism.

In order to solve such problems, in the present invention, the operation slider is frictionally connected (C-coupled) to the knock mechanism via a web that completely penetrates and engages with the slit-shaped opening in the sleeve wall.
Furthermore, said web is integrally molded in the center of the operating slide and further has a pawl-like cylindrical receptacle at the end of said web towards the knocking mechanism, said receptacle being able to pin the knocking member during assembly. such end of the web is adapted to snap into engagement with the knocking mechanism via a I made it seem like it was.

By designing the actuating slide with a web in this way, the actuating slide can be connected in a simple manner via the snap seat with the knocking mechanism. At the same time, the actuating slide is positioned in the shaft and prevented from falling during the preparatory stage for assembling the knocking mechanism.

In an advantageous embodiment of the invention, the width of the web molded in the center of the operating slide is the same as the width of the slit-like opening in the sleeve wall, so that the web is held and guided within the opening. This likewise serves for an advantageous positioning of the actuating slide before assembly of the knocking mechanism.

In a further advantageous embodiment (/?:), the actuating slide is arranged in a tray-shaped recess in the sleeve wall in such a way that it extends up to a groove in which the outer contour of the writing instrument is approximately maintained, and in addition the length of the web is The cylindrical receptacle at the end of the web is configured to center, hold and guide the pin of the knocking part when the actuating slide is inserted into the recess. This ensures that the operating slide hardly curves out of the design of the writing instrument, and that a fixed connection between the knocking mechanism and the operating slide is ensured.

In yet another embodiment, the operating slide is arranged offset by 90 degrees with respect to the clip of the shaft. The advantage obtained by this is that the position of the writing instrument in the hand hardly needs to be changed for lead operation, and that the writing instrument can be moved in two straight lines on the index finger of the writing hand when pressing the operating slider. It is to be in contact with the point bearing part.

It is further advantageous if the surface of the actuating slide has knots, lips, corrugations or depressions. This prevents your thumb from slipping during operation.

FIG. 1 shows a longitudinal section through the upper half of a writing instrument having a shaft 1, on one side of which a clip 2 is integrally molded. Due to the shape of modern writing instruments, the upper part of the shaft 1 is tapered, inter alia by making the upper part 3 of the writing instrument approximately uniform in thickness and forming the clip 2 integrally molded into the writing instrument. There is. This means that the knocking member of the knocking mechanism 5, which is normally arranged centrally at the upper end of the shaft 1, can now be operated by the clip 2 without risk of material destruction.
and the axis 1 can no longer be accommodated in the area 17. Therefore, the knocking mechanism 5 (-1) is arranged in the cylindrical central part of the shaft 1 on the underside of the tapered upper part of the shaft.

Since the well-known knock mechanism 5 is used in this type of writing instrument, as can be seen from the enlarged longitudinal sectional view in FIG.
An operation slider 6 is provided shifted by 90 degrees with respect to the main body. A web 7 is integrally molded in the center of the operating slide 6, which web is held and guided in a slit-like opening δ of the shaft 1, and the knocking mechanism 5 and the operating slide 6 are connected by the web 7. Ru. Operation slider 6
has a claw-like cylindrical receiving part 9 at the end facing the knocking mechanism 5 (see FIG. 3), and this receiving part has a shape similar to the pin 11 of the knocking mechanism 5 integrally formed with the knocking member 10. Connectively and frictionally coupled.

Jin dl has two struts ξ12.13',
The mutual spacing of the stops corresponds to the height of the web 7. The end of the 2-in 11 above the strut horn ξ13 is
12. Tapered frustoconically to a diameter smaller than the diameter of the cylindrical area of the pin between 1'3. The pawl-like cylindrical receptacle 9 in FIG. 3 has an outer wall diameter slightly larger than one of the webs 7, without completely enclosing the pin ll', and is therefore able to operate by deflecting during assembly. Due to the weight of the slide 6, the receptacle 9 can easily pass through the slot-like opening 8 of the shaft 1 without falling out again. The inner diameter of the receptacle 9 is chosen such that the pawl tightly surrounds the cylindrical area of the pin 11 in the assembled state.

The operating slide 6 is fitted into a tray-shaped cutout in the sleeve wall, so that the outer contour of the writing instrument is approximately maintained up to the groove. In short, the operating slide is integrated into the design of the writing instrument, with the exception of the wavy or rounded surface 15. In this case, what about operation slider 6? On the ftD surface, pin 11 is
A distance is provided from the center point of the entire receiving part 9 so that the slider 6 will not be bent or twisted when the slider 6 is slidably fitted into the sliding part 14 in the tray-shaped notch part 16.

Automatic belt conveyor assembly of writing instruments is carried out in a simple manner as follows.

In the slit-like opening δ of the cutting shaft 1, the web 7 is compressed into the claw-like receiving part 9 and is sized to the desired size.

Since the width of the web 7 corresponds exactly to the slit width of the opening 8, the actuating slide 6 is clamped into the recess 16, so that the receptacle 9 is forced to be centered in the shaft 1. ing. In the next assembly step, the knocking mechanism 5 is brought into the shaft 1 of the writing instrument from below. If the truncated conical end of the pin 11 is inserted into the pawl-like cylindrical receptacle 9 from below, the receptacle 9 is inserted between the webs or the receptacles 612, 13 of the pin 11. is expanded during movement until it snaps into engagement based on material elongation.

This ensures simple and reliable fixing of the operating slider 6 and the knock mechanism 5. It is particularly advantageous in this case for the actuating slide to be arranged offset by 90 degrees with respect to the clip 2 molded on the shaft, so that the actuating slide can be operated by the thumb of the writing hand and by the hand. This is possible without changing the position of the writing implement you are holding.

In this case, the narrow side of the clip becomes articulatingly advantageous,
And the writing instrument should be securely attached to the first joint of the index finger of the writing hand.
r, i It is supported to ensure a linear two-point support. Therefore, even if the pressure of the thumb on the operating slider is not centered, the writing instrument is supported without twisting via the two-point support in another area.
