Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Supplementary or in addition to the advantageous embodiments and further developments of the teaching already discussed, embodiments of devices according to the invention shown to the extent of FIGS. 1 and 2 are explained in more detail in the drawings. However, the examples discussed with reference to the drawings do not limit the invention to the examples shown. In discussing the embodiments with reference to the drawings, generally preferred embodiments and further developments of the teaching are also shown.

[0044] Further developments of the advantageous embodiments described above with features of the embodiments described below, just like further developments of the embodiments described below with features of the embodiments described above, expressly form further advantageous embodiments of the invention, and thus form part of the present disclosure.

[0045] FIG. 1 shows a preferred embodiment of a numbering unit according to the invention, which in turn comprises an upper part and a lower part; and

[0046] FIG. 2 shows an embodiment from FIG. 1 in an exploded view, with the upper part and the lower part of the numbering unit shown at a distance from each other.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0047] FIG. 1 shows a preferred embodiment of a numbering unit 1 according to the invention. The numbering unit 1 comprises an upper part 2 and a lower part 3.

[0048] Here and exemplary, the lower part 3 is reversibly fixed to the mounting ring 4 of a numbering machine (not shown). For this purpose, screws 5 extend through the clamping hook 6A on the front side. The clamping hook 6A and clamping lever 6B are clamped against each other by the opposite clamping lever 6B, whereby the lower part 3 is fixed to the mounting ring 4.

[0049] In the upper part 2, two tiltable tensioning levers 7 are arranged diagonally opposite each other. The tensioning levers 7 extend essentially vertically and comprise an actuation section 701 at the top for the user and a hook section 702 at the bottom (see FIG. 2) for engagement in the lower part 3.

[0050] A spring 8 acts between the upper part 2 and each tensioning lever 7, pretensioning the tensioning lever 7 in a suitable manner.

[0051] In a similar way, the clamping lever 6B of the lower part 3, which acts on the mounting ring 4, is pretensioned by its own springs. In this respect, a reversible fixation of the lower part 3 on the mounting ring 4 is also provided here.

[0052] The upper part 2 comprises the numbering mechanism 21 with the type wheels 22.

[0053] Further in relation to the upper part 2, the user can pivot the tensioning levers 7 away from the lower part 3 by actuating them against the force of the springs 8 and thus remove the upper part 2 from the lower part 3 very quickly. Conversely, the upper part 2 can in this way be moved towards the lower part 3 and be arranged or engaged on the latter. By withdrawing the actuating force on the tensioning levers 7, these then pivot into the lower part 3, and thus the upper part 2 is fixed and/or clamped to the lower part 3. This connection between upper part 2 and lower part 3 can also be established in just a few seconds.

[0054] FIG. 2 shows the embodiment from FIG. 1 in an exploded view, with the upper part 2 and the lower part 3 of the numbering unit 1 shown at a distance from each other.

[0055] It can be clearly seen here that the underside 201 of the upper part 2 engages with a lug 202 in a central groove 301 of the lower part 3. The tensioning levers 7, whose lower hook section 702 is clearly visible here, also engage in further suitable lateral recesses 302 or grooves in the lower part 3.

[0056] Furthermore, both the lug 202 and the central groove 301 comprise a corresponding cross shape, i.e. the lug 202 and the central groove 301 each comprise portions oriented perpendicularly to one another. This inevitably leads to an exact positioning of the upper part 2 relative to the lower part 3 when the upper part 2 is advanced to the lower part 3, as there no longer exist any degrees of freedom in the positioning of the upper part 2 perpendicularly to the underside 201 of the upper part 2.

[0057] With regard to FIG. 2, it should otherwise be noted that reference signs already shown in FIG. 1 and already explained above in this respect are not explained again in part with reference to FIG. 2. For the explanation of such reference signs and the associated technical features, reference is made in full to the above description of FIG. 1 in order to avoid repetition.
