Description

Heinrich Morlock company, Pforzheim. Exchangeable writing pen, especially ballpoint pen The innovation relates to an exchangeable writing pen, in particular special ballpoint pens with two parallel in the pen casing lying, preferably by means of push handles reaching through guide slots, brought from the rest to writing position and locked in place, writing medium carriers, in particular sleeves for writing cartridges.

Bs are two-color and multi-color interchangeable pens in numerous designs known in which when a cartridge is brought forward in the writing position is triggered automatically and is retracted into the rest position under the action of a spring. The mechanical designs developed for this are relatively complicated and therefore expensive. The long ones used in single-color ballpoint pens can also be used Writing cartridges with a very long writing time are bad in these so-called automatic ones Place exchangeable pens.

Furthermore, two-color interchangeable pens are not automatic Execution known in which the writing cartridges by hand by means of guide slots The push handles reaching out to the pen jacket must be brought back and forth * With these interchangeable pens there is a partition in the pen casing Guide the parallel writing medium carrier provided. On one of these not automatically working two-color Weohsel pen now refers to the present innovation, with a particularly expedient and safe working configuration is achieved.

The change pen according to the innovation is now marked in that in the pen casing a leaf spring bulging on both sides; in particular a leaf spring loop for guiding and resilient locking of the appropriate means Push handles in jacket slots running both writing material carriers, in particular sleeves is provided. This makes it easier to install the two writing medium carriers or sleeves in the pen casing by pressing down the leaf spring loop, the push handles being held in the guide slots under the action of a spring will.

In detail, the leaf spring loop can spring apart into two The leaf spring struts run out and at the end of the loop with the one inserted at the end of the jacket Clip brackets connected, in particular screwed, thereby making it easy to manufacture and assembly of the Change pen achieved according to the innovation will.

Furthermore, it is practical to use the guide slots in the Pen jacket as well as locking slots in the middle for resilient locking of the means End tabs engaging writing material carrier provided in the rest and writing position. The guide slots are provided in the pencil jacket end part, in which then a pencil sheath tip part can be inserted, in the drawing is for example an embodiment of the interchangeable pen according to the innovation shown and 1 and 2 show the front and side views of a novel two-color ballpoint pen in the rest position in longitudinal section and FIG. 3 shows the side view of the two-color ballpoint pen corresponding to FIG. 2 in the writing position and partially cut open, as well as FIG. 4 shows the cross section along the lines IV-IV of FIG.

The illustrated two-color ballpoint pen has a pencil jacket end portion 1, in which a pencil sheath tip part 2 is inserted. In the end of the coat is according to the innovation the leaf spring loop 3, which in two spring apart Leaf spring struts runs out, connected to the inserted clip bracket 4 by the end head screw 5. On both sides of the leaf spring loop 3 writing material sleeves 6 run, which means Slide it 7 through guide slots 8 in the pen casing. over the guide slots 8 and in the middle thereof locking slots 9 are provided in which the writing material sleeves 6 spring into place by means of end tabs 10 with the intermediary of the spring loop 3 and thereby in rest or. Writing position are held. In the two of them in the pencil case The parallel writing material sleeves 6 are then the ballpoint pen cartridges 11 held interchangeably by pushing in up to the stop ring 12 under friction.

As can be seen from this, it is not just a simple assembly achieved with the new two-color ballpoint pen from a few individual parts, rather Long ballpoint pen cartridges with a very long service life can also be accommodated here. Finally, there is the operation and functionality of the new two-color ballpoint pen simply ud not susceptible to failure. The Individual parts made possible.
