Description
kulisse 3 mittels eines Mitnehmers 4 verbunden ist, der in einem Führungsschlitz 5 der Kulisse 3 gleitet.Link 3 is connected by means of a driver 4 which slides in a guide slot 5 of the link 3.
An der Kulisse 3 ist mit einer seiner Drehachsen ein Spiegel 6 im Punkt 7 gelenkig befestigt. Über eine zweite Drehachse, die parallel zu der ersten liegt, ist der Spiegel mittels eines schwenkbaren Zwischengliedes 8 gelenkig mit dem Kameragehäuse (im Bild nicht dargestellt) verbunden.A mirror 6 is articulated at point 7 on the backdrop 3 with one of its axes of rotation. Over a The second axis of rotation, which is parallel to the first, is the mirror by means of a pivotable intermediate member 8 articulated to the camera housing (not shown in the picture).
Die Kulisse 3 wird in ihrer unteren Lage an einem Vorsprung 9 mittels eines Hebels 10 festgehalten, der durch eine Feder 11 an einem Primärhebel 12 angedrückt wird. Der Primärhebel 12 steht unter der Wirkung der Zugkraft einer Feder 13 und ist unmittelbar unter einem Auslöseknopf 14 des Verschlusses angeordnet. Eine Achse 15 des Primärhebels 12 ist durch Einwirkung des in Ruhestellung eingeschalteten federangetriebenen Ausrückmechanismus (Fig.2) axial verschiebbar, bei dem eine in Ruhestellung zusammengedrückte Feder 16 vorgesehen ist. Die Achse 15 wird durch einen Sperrhebel 17 festgehalten, der unter der Wirkung einer Feder 18 steht, der in einen Ausschnitt der Achse 15 gedrückt wird.The link 3 is held in its lower position on a projection 9 by means of a lever 10, the is pressed against a primary lever 12 by a spring 11. The primary lever 12 is under the Effect of the tensile force of a spring 13 and is immediately below a release button 14 of the shutter arranged. An axis 15 of the primary lever 12 is switched on by the action of the in the rest position spring-driven release mechanism (Fig.2) axially displaceable, in which one in the rest position compressed spring 16 is provided. The axis 15 is held in place by a locking lever 17, which is under the action of a spring 18 which is pressed into a section of the axis 15.
Ferner ist ein zwischenliegender Drehhebel 19 mit drei in verschiedene Richtungen weisenden Armen 20,21, 22 vorgesehen. Der Hebel 19 ist im Schnittpunkt 23 der drei Arme drehbar gelagert. Der Arm 20 ist mit dem Ende des Sperrhebels 17 verbunden. Der Arm 21 ist so ausgebildet und angeordnet, daß der mit einem Vorsprung 24 der Kulisse 3 in Eingriff steht; der Arm 22 liegt frei zwischen einem Bauteil 25, durch den der Verschluß ausgelöst wird, und einem beweglichen Bauteil 26 des Verschlusses.Furthermore, there is an intermediate rotary lever 19 with three arms pointing in different directions 20, 21, 22 are provided. The lever 19 is rotatably mounted at the intersection 23 of the three arms. The arm 20 is connected to the end of the locking lever 17. The arm 21 is designed and arranged so that which is in engagement with a projection 24 of the link 3; the arm 22 lies freely between a component 25, by which the shutter is released, and a movable component 26 of the shutter.
Beim Herunterdrücken des Auslöseknopfes 14 des Verschlusses bringt der Primärhebel 12 den Hebel 10 außer Eingriff mit der Kulisse 3, die unter der Wirkung der Antriebstrommel 2 gedreht wird und den Spiegel 6 in die obere Stellung hochklappt. Hierbei drückt der Vorsprung 24 der Kulisse 3 auf den Arm 21 des Hebels 19, der mit dem Arm 22 den Auslösebauteil 25 des Verschlusses betätigt und mit dem Arm 20 die Freigabe der Achse 15 durch den Sperrhebel 17 bewirkt.When the release button 14 of the lock is pressed down, the primary lever 12 brings the lever 10 out of engagement with the link 3, which is rotated under the action of the drive drum 2 and the Mirror 6 folds up into the upper position. Here, the projection 24 of the link 3 presses on the arm 21 of the lever 19, which actuates the release component 25 of the lock with the arm 22 and with the Arm 20 causes the axis 15 to be released by the locking lever 17.
Die Achse 15 (F i g. 2) wird zusammen mit dem Primärhebel 12 durch die Feder 16 verschoben und aus dem Bereich des Auslöseknopfes 14 gebracht, wodurch ein weiteres Einwirken des Knopfes 14 auf den Auslösemechanismus ausgeschlossen ist.The axis 15 (FIG. 2) is moved together with the primary lever 12 by the spring 16 and brought out of the area of the release button 14, whereby a further action of the button 14 on the trigger mechanism is excluded.
Zum Zurückführen der Achse 15 in ihre Ausgangsstellung dient ein Stößel 27 (F i g. 2).A plunger 27 (FIG. 2) is used to return the axle 15 to its starting position.
Der Arm 21 hält infolge des Zuges einer Feder 28 die Kulisse 3 und den Spiegel 6 in der hochgeklappten Stellung fest.The arm 21 stops as a result of the tension of a spring 28 the backdrop 3 and the mirror 6 in the folded up Position fixed.
Beim Schließen der zweiten Verschlußbahn des Schlitzverschlusses (nicht dargestellt) drückt der Bauteil 26 auf den Arm 22 und bringt den Vorsprung 24 der Kulisse 3 außer Eingriff mit dem Arm 21, wonach der Spiegel 6 in seine Ausgangsstellung zurückkehrt.When closing the second fastener web of the focal plane shutter (not shown) pushes the Component 26 on the arm 22 and brings the projection 24 of the link 3 out of engagement with the arm 21, after which the mirror 6 returns to its original position.
