It goes without saying that this is not an instrument for exacting accuracy, however, there is a practical element that allows the pen to be used for to use all of his uses-and besides you, wine it's about drawings, schemes or other work to use the compass in order to learn about its peculiarities To make use of it.

A parent advantage of this element is that the Investment or manufacturing costs of the same are very low are, after it consists of a simple plastic sleeve, the cost of which is practically negligible and in v / elcher an inner compartment is provided, which is arranged somewhat displaced with respect to the axis of the sleeve but can accommodate the flexible ballpoint pen insert.

Following the surface lines of this sleeve is aussen.eine vertical recess with sufficient cross-section for inclusion of a compass shank provided, which, when folded, completely rests against the sides of the outer surface of the sleeve.

Another special feature of the invention is that this leg has an extension at its upper end, which is attached, guided and adapted to a transverse pin provided on the sleeve head. On the sleeve head, a pair of opposed grooves is further arranged to allow the articulation of this arm, whereby ^DER: same unfolded and the radius may be set to be drawn circle of the.

Another special feature is that on this pin, which protrudes beyond the upper end of the sleeve, the grooved

In the following, an embodiment of the invention is based on schematic drawings, explained in more detail. ■

Fig; 3 is a plan of the entire object.

To explain the reference numbers in the drawings, it should be mentioned that 1 denotes the plastic sleeve, which has a compartment 2 inside, in which the flexible and exchangeable insert 4 of the ballpoint pen is housed, much of the latter ending in the writing tip 5 .

Following the dumbbell lines of this sleeve, a vertical cutout 3 is provided where the fixed point compass leg 6 housed, -is, which can be well housed with its hidden needle 8 in the recess 3, wherein To regulate this needle 8, the clamping wheel 7 is provided is. For its placement in this cutout line 3, a circular extension 3a is provided exactly at the level of its coupling.

This leg 6 has the tab at its upper end on, which led to Cuerstift 10, adjusted and attached

is, in a completely opposite sense "with respect to a pair of grooves 11, the grooves of which are diametrically opposed and allow the free articulation of this end 9 on the pin. On this pin 10 is astride on the flap 9 the hinge clamp 13 on which the handle 12 is screwed, the 'for better handling of the circle serves.

One sees clearly that when the leg β of the compass is folded, one uses the ballpoint pen for the normal Can use use, because the diameter of the sleeve 1 will increase slightly in any case, but in the usual Extent, and allow the full use of the writing implement, which when the leg 6 is unfolded and is inserted in a point with a radius corresponding to its opening, as a drawing tip serves.
