Description

Reißschiene mit zur Gerad- bzw. Parallelführung eingerichtetem Führungskopf Es sind Spa-ninvorrichtungen fÜr Reißschknen bekanntgeworden, bei denen ein Führungskopf unter der Wirkung abgefederter Spannhebel nachgiebig an der Reißbretts,elte, anliegt. Diese SpannvorrichtungenIegen die Schiene auf dem Reißbrett verschieblich fest, aber sk sind nicht -geeignet, gleichzeitig als Gerad- oder Parallelführungen zu wirken.Tear bar with guide head set up for straight or parallel guidance There are clamping devices for drawbars have become known in which a guide head under the action of the spring-loaded tension lever, it is yielding against the drawing board. These clamping devices fix the rail on the drawing board so that it can be moved. but sk are not suitable, at the same time as straight or parallel guides works.

Es ist die Aufgabe der Erfindung, eine derartige Spannvorrichtung zu schaffen, die zugleich als Geradführung für die Reißschiene wirkt. Erfindungsgemäß wird diese Aufgabe dadurch gelGst, daß die an oder in dem Fährungskepf angeordneten Spannliebel als beweglich miteinander gekuppelte Hebel .ausgebildet sind,- an deren einen Enden, je eine Rolle angebracht ist und an deren anderen miteinander gekuppelten Enden eine Feder angreift.It is the object of the invention to create a tensioning device of this type which at the same time acts as a straight guide for the tear bar. According to the invention this object is gelGst that arranged on or in the Fährungskepf Spannliebel are .ausgebildet than movably coupled to one another lever - on whose one ends, one each roller is mounted and which engages a spring at the other ends coupled together.

Die Zeichnung zeigt als Ausführungsbeispiel eine. Reißschiene, die mit ebner Spann-und Geradführungsvorrichtung nach der Erfradung versehen ist.The drawing shows an exemplary embodiment. Tear bar that is provided with an even clamping and straight guiding device after the erfradung.

Die auf dem Zelchenbrett 2 nach auf- oder abwärts verschlebbare Reißschiene i, die zweaIrmäßigeine obere Griffleiste i' hat, weist an beiden Enden je einen gegen die beiden Seltenkanten des Brettes anliegenden An.-schlag- oder Führungskopf 3 und 4 auf. Der Führungskopf 3 ist fest an der Schiene i angebracht und liegt an Üer einen Brettseite an. Der Führungskopf 4 liegt gleichfalls fest an der anderen Brettseite an; an, ihm sind Spannhebel 7 befestigt, die als miteinander gekuppelte, z. B. um die Drehpunkte 6 schwenkbar gelagerte Hebel ausgehildet sind.The i on the Zelchenbrett 2 after up or down verschlebbare tear rail zweaIrmäßigeine upper handle strip has i ', has at both ends a bearing against the both side edges of the board An.-impact or guide head 3 and 4. The guide head 3 is firmly attached to the rail i and rests on one side of the board. The guide head 4 also rests firmly against the other side of the board; on, him clamping levers 7 are attached, which as coupled together, z. B. pivotally mounted levers about the pivot points 6 are formed.

An den freien Enden dieser Spannhebel 7 ist je eine Rolle 5 angebracht, während an den anderen beiden miteinander gekuppelten Enden dieser Spannhebel. eine Feder 8 angreift, die sich gegen. die Reißschiene i oder Z> den Führungskopf 4 abstützt.A roller 5 is attached to each of the free ends of these tensioning levers 7 , while these tensioning levers are attached to the other two ends which are coupled to one another. a spring 8 engages, which is against. the tear bar i or Z> supports the guide head 4.
