Description
Die Erfindung betrifft eine Vorrichtung zum Einstellen der Entfernung bei geschlossenen Spreizenkameras durch einen mit den Scherenspreizen in Verbund tretenden auslösbaren Stellteil. Bei bekannten Kameras dieser Art ist dieser an der Kamera selbst angebracht und umfaßt einen Vorsprung an einem Schieber, in dessen Aussparung sich ein Stift an dem frei beweglichen Ende der ίο Spreizen verschiebt.The invention relates to a device for adjusting the distance when closed Spreader cameras by a trigger that joins the scissor spreader Control part. In known cameras of this type, this is attached to the camera itself and includes a projection a slide, in the recess of which there is a pin on the freely movable end of the ίο Spreading moves.
Demgegenüber besteht die Erfindung darin, daß der Stellteil an einem durch an sich bekannte Mittel, z. B. eine Schraubenspindel, verstellbaren Zahnsektor angelenkt ist und mit einer Aussparung einen Stift umfaßt, der sich am einen verschiebbaren Spreizenende befindet.In contrast, the invention consists in the fact that the actuating part is connected to a known per se Means, e.g. B. a screw spindle, adjustable tooth sector is articulated and comprises a pin with a recess which is located at a sliding end of the spreader.
Die Erfindung ist zeichnerisch wiedergegeben. The invention is shown in the drawing.
so Abb. ι zeigt eine Aufsicht hierzu bei geschlossener Kamera,so Fig. ι shows a plan view of this with the closed Camera,
Abb. 2 nach erfolgtem Spreizenauszug. Am oberen Ende a1 der Hilfsachse α innerhalb des Kameragehäuses b befindet sich ein *5 Gewindesegment c. In dieses greift eine Mikrometerschraube d ein. Ein Hebel e ist mit seinem einen Ende am Segment bei c1 angelenkt. Eine Feder f preßt den Hebel c der Innenseite d1 der Kamerarückwand zu. Am anderen Ende des Hebels e befindet sich eine Aussparung e1, die oberhalb einer Füh- | rung g, in welcher die Scherenspreizenachse h sich entlang bewegt, das Einfedern des Teiles g zur Spreizenachse h veranlaßt. Die Wirkungsweise der Vorrichtung ist folgende: Durch Drehung der Mikrometerschraube d bei geschlossener Kamera wird das Gewindesegment c um seine Achse α gedreht. Dabei bewegt sich der Hebel e, den seine Feder f der Innenseite b1 der Kamerarückwand zupreßt, mit seinem äußeren Ende an dieser entlang und bringt die dort vorhandene Aussparung e1 in bestimmte Entfernung zur Spreizenachse h, die in zurückgeschobenem Zustande sich am äußersten Ende der Führung g befindet.Fig. 2 after the spreading mechanism has been pulled out. At the upper end a 1 of the auxiliary axis α within the camera housing b there is a * 5 thread segment c. A micrometer screw d engages in this. One end of a lever e is hinged to the segment at c 1. A spring f presses the lever c on the inside d 1 of the rear wall of the camera. At the other end of the lever e there is a recess e 1 which is above a guide | tion g, in which the scissor spreading axis h moves along, causes the deflection of the part g to the spreading axis h . The operation of the device is as follows: By turning the micrometer screw d with the camera closed, the thread segment c is rotated about its axis α. The lever e, which its spring f presses on the inside b 1 of the camera rear wall, moves with its outer end along this and brings the recess e 1 present there at a certain distance from the spreading axis h, which in the pushed-back state is at the extreme end of the Guide g is located.
Wird nun der Kameravorderteil erfaßt und die Scherenspreizen aus dem Kamerainneren herausbewegt, so wird die Spreizenachse h in der Führung g der Ausparung e1 verschoben. Sobald diese über die Achse h schnappt, wird diese festgehalten und dadurch der Auszug der Scherenspreizen begrenzt. Die vor dem öffnen der Kamera erfolgte Einstellung des Hebels e und damit der Auszug der Scheren ist in bekannter Weise oberhalb der Hilfsachse α mittels Skala und Index ablesbar.If the front part of the camera is now detected and the scissors spreaders are moved out of the interior of the camera, the spreading axis h is shifted in the guide g of the recess e 1. As soon as this snaps over the axis h , it is held and the extension of the scissor braces is limited. The setting of the lever e made before opening the camera and thus the extension of the scissors can be read in a known manner above the auxiliary axis α by means of a scale and index.
