Description

dient ein Tastenführungsblech 4 sowie eine obere Abdeckhaube, die in den Zeichnungen nicht gezeigt ist. Zwischen je zwei Tasten 1 sind Sperrplättchen 5 angeordnet. Diese Sperrplättchen 5 sind in einer Halteplatte 6 befestigt, welche oberhalb des Tastenführungsbleches 4 angeordnet ist und mittels Schrauben und Abkröpfungen 7, 8 und 9 mit dem Tastenführungsblech 4 verbunden ist.serves a key guide plate 4 and an upper cover, which is not shown in the drawings. Locking plates 5 are arranged between every two buttons 1. These locking plates 5 are in a holding plate 6 attached, which is arranged above the key guide plate 4 and by means of screws and bends 7, 8 and 9 are connected to the key guide plate 4.

Jedes der Sperrplättchen 5 hat eine Form, wie sie sich in vergrößerter Darstellung aus F i g. 5 ergibt. Demnach ist das Sperrplättchen 5 an seiner oberen Kante mit einer Nase 10 versehen. Die obere Begrenzungsfläche 11 des Sperrplättchens 5 ist wie ein Satteldach ausgebildet, d. h., sie besitzt eine obere KanteEach of the locking plates 5 has a shape as shown in an enlarged view from FIG. 5 results. Accordingly, the locking plate 5 is provided with a nose 10 on its upper edge. The upper boundary surface 11 of the locking plate 5 is designed like a gable roof, d. i.e., it has a top edge

13 und 14. An ihrem unteren Ende sind die Sperrplättchen 5 mit zwei verlängerten Teilen 15 und 16 versehen, die über die untere Begrenzungskante 17 der Sperrplättchen 5 hinausragen und dazu dienen, in Ausnehmungen 18 der Halteplatte 6 eingesetzt zu werden. Zur Befestigung der Sperrplättchen 5 in der Halteplatte 6 sind an den unteren Teilen 15 und 16 noch Vorsprünge 19 vorgesehen, mittels derer sich die Sperrplättchen 5 mit ihren unteren Teilen 15 und 16 in den Ausnehmungen 18 abstützen. Die Sperrplättchen sind vorzugsweise aus einem elastischen Kunststoffmaterial gefertigt, derart, daß man die unteren Teile 15 und 16 beim Einsetzen der Plättchen auseinanderpressen kann und diese sich dann selbsttätig in den Ausnehmungen 18 der Halteplatte 6 verhaken. 13 and 14. The locking plates 5 with two elongated parts 15 and 16 are at their lower end provided, which protrude beyond the lower boundary edge 17 of the locking plate 5 and are used in Recesses 18 of the holding plate 6 to be used. For fastening the locking plate 5 in the Holding plate 6 are also provided on the lower parts 15 and 16 projections 19, by means of which support the locking plates 5 with their lower parts 15 and 16 in the recesses 18. The lock tokens are preferably made of a resilient plastic material, such that the lower Parts 15 and 16 can press apart when inserting the platelets and these then automatically hook in the recesses 18 of the retaining plate 6.

Wie F i g. 4 zeigt, hat die Halteplatte 6 ganz bestimmte Ausnehmungen, und zwar je zwei für jedes Sperrplättchen 5, derart, daß jeweils zwischen zwei benachbarten Tasten je ein Sperrplättchen 5 vorhanden ist. So ist beispielsweise zwischen den Tasten »S« und »9« ein Sperrplättchen 5 vorgesehen, aber auch zwischen den Tasten »8« und »5« und zwischen den Tasten »9« und »6«. So wird beispielsweise das Sperrplättchen 5 zwischen den Tasten »8« und »9« innerhalb der Platte 6 in die Ausnehmungen 20 und 21 eingesteckt, das Sperrplättchen 5 zwischen den Tasten »8« und »5« in die Ausnehmungen 22 und 23 und das Sperrplättchen 5 zwischen den Tasten »9« und »6« in die Ausnehmungen 24 und 25.Like F i g. 4 shows, the holding plate 6 has very specific recesses, two for each Locking plate 5 in such a way that a locking plate 5 is present between two adjacent keys is. For example, a locking plate 5 is provided between the "S" and "9" keys, but also between the »8« and »5« keys and between the »9« and »6« keys. For example, that is Locking plate 5 between the buttons "8" and "9" inside the plate 6 in the recesses 20 and 21 inserted, the locking plate 5 between the buttons “8” and “5” in the recesses 22 and 23 and the locking plate 5 between the buttons “9” and “6” in the recesses 24 and 25.

F i g. 2 zeigt die Lage der Sperrplättchen 5 in ihrer Ruhestellung. In dieser Stellung ist die Nase 10 in dem freien Raum zwischen je zwei Tastenknöpfen 2. Wird dagegen eine Taste betätigt, wie dies die F i g. 3 zeigt, dann werden zwei Sperrplättchen 5 verschwenkt, was durch die satteldachförmige Ausbildung der oberen Begrenzungsfläche 12 der Sperrplättchen 5 begünstigt wird. Die beiden Flächen 13 und 14, die der gedrückten Taste abgewendet sind, verhindern nun das Herabdrücken der benachbarten Tasten, wie sie sich eindeutig aus F i g. 3 ergibt.F i g. 2 shows the position of the locking plates 5 in their rest position. In this position, the nose is 10 in the free space between two key buttons 2. If, on the other hand, a key is pressed, as shown in FIG. 3 shows, then two locking plates 5 are pivoted, which is due to the gable roof-shaped training the upper boundary surface 12 of the locking plate 5 is favored. The two surfaces 13 and 14, which are turned away from the pressed key, now prevent the next one from being pressed down Keys as clearly shown in FIG. 3 results.
