Such pens have two refills, each of which a certain color, e.g. blue or red, and you can after. Write your wish with one or the other of the mines while the other is withdrawn.

The basic object of the invention is to to create such a two-tone penis, its Control mechanism extremely simple and robust is.

The two £ «r & £ g $ writer according to the invention has one

Holder, the upper part of which with »a diametrical partition is stranding, on both sides of which actuating tappets for the "two leads adjustable in the longitudinal direction inside the holder against the force of a spring slidably lies. A cradle is mounted on the diametrical partition wall in the lower part, which two on the side has protruding pins, each of which cooperates with a recess in one or the other control tappet, the recesses, with the exception of a mounting groove, symmetrical to one another to the plane of the partition wall lie.

The profile of each recess is such that under the action of one or the other φ & χβ return springs of the mines, the cradle is always swiveled back positively to the same side. It is moved slightly out of this position when one of the plungers is pressed in, the locking of which in the writing position then takes place through the action of the other plunger, which remains retracted and which moves back into its starting position.

The invention is described below with reference to the drawings explained in more detail using an example:

The upper part of the cap 2 ends in a diametrical one. Partition 3> which determines the height of the ballpoint pen and the lower part of which has a cylindrical transverse bearing in which the cylindrical head part 4 of a cradle 5 is inserted. In the interior of the cap 2 and on both sides of the partition 3, two actuating plungers 6, 7 are attached, each of which encompasses the head of a writing refill 8 with its lower part. The cap 2 is open at the level of the upper part of the plungers 6, 7. These latter can be pressed against the force of return coil springs 9, which are located around the corresponding mines 8. Each spring 9 is between the plunger 6 or 7 and one inside. of the holder 1 lying and firmly connected to this guide bush 10 clamped.

the effect of the return springs 9 is limited upwards.

The cradle 5 and its cylindrical head 4 with which it is stored in the bore 3 are almost the same Thickness as the partition 3 made. In contrast, in our part of the cradle 5 there are two pins 17 and 18, which protrude on both sides in such a way that they with the corresponding recesses 12 and 14 of the plunger 6 and 7 'as shown in FIGS. 5 and 10, interact.

The mode of operation of the arrangement is as follows:

When the two mines 8 in the Pig. 1 and 2 shown are in the retracted position, the two plungers 6 and 7 are also pushed back upwards by their springs 9 and lie with their edges 15 and 15a, respectively

on the edge 16 'of the cap 2. Due to the simultaneous

Effect of the pin 17 pressed into the ridge 12d between the ramps 12b and 12c and the pin 18 pressed into the part 14d between the ramps 14b and 14c
the cradle 5 is held in a predetermined inclined position, ie it is _{pivoted x} to the right in FIGS.

If you now move the plunger 7 vertically into the interior of the

909850/0103

8, the cradle 5 is pivoted to the left under the action of the ramp 14c cooperating with the pin 18, whereby at the same time the counterpressure of the plunger 6 is shifted somewhat downwards, since the pin 17 fmS the cradle 5 in turn is pressed along the ramp 12b of the recess 12. When the plunger 7 is pushed in so far that the transverse part 14a reaches the height of the pin, the latter, under the action of the restoring force of the spring 9 of the plunger 6, which moves the ramp 12b of the cradle to the right in FIG. 9, is in this transverse part 14a swiveled in. At this moment there is a slight increase in the plunger 6 until it has reached its starting position, while the cradle 5 is pivoted completely to the right and is held by the pin 17, which rests on the part 12b ₃ during which then on the bottom of the transverse part 14a of the Pin 18 resting against the plunger 7 causes this plunger 7 to be locked in the writing position.

When the plunger 6 is then pressed in, the cradle 5 is first pivoted to the left by an analogous action of its ramp 12c, until its pin exits from part 14a. The unlocked in this way plunger 7 is reset by its leather 9,

909850/0103 - ⁸ ~

whereupon, when the plunger 6 is pushed in further, it is locked in the writing position, as explained above with the plunger 7 remaining in the retracted position.

The groove 13 is used to assemble the pen. First the plunger 7 is inserted in the retracted position, whereupon the cylinder head 4- of the cradle 5 is inserted into the bore 3 and the cradle is guided at right angles to the axis of the recorder. After the cradle has been inserted, the plunger 6 is pushed in through the interior of the pen and, as a result of the arrangement of the groove 13, can be pushed over the pin 17 until it lies in the recess 12.

According to the invention, the edges 15 and 16 be replaced by other known stop devices that limit the movement of the plungers 6 and 7 upwards.
