Abstract

A focussing mechanism for a telescope or pair of binoculars uses a spring (1) which can be controlled by the operator whilst holding the glasses with both hands. The instrument is lightly pressed against the eyes or released so that the spring causes the distance between the eyepiece section (3) and the lens section (7) to alter and so change the focus. A fixing screw (8) may be provided to lock the position at any preset-focus, or to act as a precision focussing adjustment.

Description

Bildschärfeeinstellung beim Kernrohr mittels einer Feder.Focus adjustment on the core tube by means of a spring.

Die erfindung betrifft eine Vorrichtung mit der man die Bildschärfeeinstellung beim Fernrohr ohne zusätzliche Handbedienung einstellen kann.The invention relates to a device with which you can adjust the focus on the telescope without additional manual control.

Zur Bildschärfeeinstellung beim Fernrohr, hauptsächlich beim Doppelfernrohr, dient meist der itteltrieb, der beide Okulare gleichzeitig verstellt, indem eine Stellschraube, von Hand gedreht, über ein Gewinde, die Achse auf der die beiden Okulare über die Knickbrücke, befestigt sind, auf und ab bewegt werden.To adjust the focus of the telescope, mainly with the double telescope, The middle drive is usually used, which adjusts both eyepieces at the same time by one Adjusting screw, turned by hand, via a thread, the axis on which the two Eyepieces are attached via the folding bridge, can be moved up and down.

Bei dieser Vorrichtung ist also immer eine Hand nötig, die die Stellschraube des leitteltriebs bedienen muß, um das Bild scharf einzustellen.With this device, one hand is always required to turn the adjusting screw the Leitteltrieb must operate in order to focus the image.

Nun sind in letzter Zeit immer größere Fernrohre auf den Markt gekommen, die gröbere micntstärke, Vergrößerung und Dämmerungsleistung haben und somit mechanisch schwerer geworden sind.Larger and larger telescopes have recently come onto the market, the coarser micnt strength, magnification and twilight performance and thus mechanical have become heavier.

Die Bildschärfeeinstellung dieser Fernrohre, wird also für die Person, die as benutzt immer schwieriger, da sie das schwere Fernrohr mit einer Hand halten muß, während sie mit der Anderen das Bild scharf stellt.The focus setting of these telescopes is therefore determined for the person the as uses more and more difficult because they hold the heavy telescope with one hand must while she focuses the picture with the other.

Will, die das Fernrohr benutzende Person, ein sich schnell bewegendes Objekt beobachten oder ihren Blick schnell hin und her schweifen lassen, mal in die Ferne schauen, mal das Nahe betrachten, so müßte sie dauernd mit der einen Hand die VDrrichtung zum Scharfstellen des Bildes betätigen, während die andere Hand das Fernrohr halten muß und somit schnell ermüdet.Will, the person using the telescope, is a fast-moving one Observe the object or let your gaze wander quickly back and forth, sometimes in To see the distance, sometimes to look at the near, she would have to keep one hand on operate the control to focus the image while using the other hand has to hold the telescope and thus tires quickly.

Die Erfindung benutzt nun eine Vorrichtung, mit der es möglich ist, daß Fernrohr mit beiden Händen zu halten und gleichzeitig das Bild scharf einzustellen.The invention now uses a device with which it is possible hold the telescope with both hands and focus the image at the same time.

Die Abbildung zeigt nun die Bildschärfeeinstellung beim Fernrohr mittels einer Feder.The figure now shows the focus setting for the telescope using a feather.

Die Feder 1 ist auf der Achse 2 so angebracht, daß sie in der Mitte des Brückenstegs 3 für die beiden Okulare 4 und auf den Anfang des ittelrohres 5 liegt.The spring 1 is mounted on the axis 2 so that it is in the middle of the bridge web 3 for the two eyepieces 4 and on the beginning of the central tube 5 lies.

Die Achse 2 geht durch das Mittelrohr 5, das über die Brückenstege 6 mit den Fernrohrkörper 7 verbunden ist, durch und trägt am unteren Ende ein Gewinde 9, auf das die Stellschraube 8 aufgeschraubt ist.The axis 2 goes through the central tube 5, which is over the bridge webs 6 is connected to the telescope body 7, through and has a thread at the lower end 9, onto which the adjusting screw 8 is screwed.

Will nun der Benutzer das Bild scharf stellen, so nimmt er das Fernrohr in beide, oder auch nur in eine Hand und drückt leicht die beiden Okulare 4 gegen die Augen0 Der Druck bewirkt, daß die Okulare 4 und der Fernrohrkörper 7 ihren Abstand zueinander gegen den Druck der Feder 1 verringern.If the user now wants to focus the image, he takes the telescope in both, or only in one hand and lightly presses the two eyepieces 4 against die Augen0 The pressure causes the eyepieces 4 and the telescope body 7 to be spaced apart reduce each other against the pressure of spring 1.

Will man den Abstand wieder vergrößern, so läßt man im Druck nach und die Feder 1 vergrößert den Abstand wieder.If you want to increase the distance again, you let up in the pressure and the spring 1 increases the distance again.

Auf diese Weise findet man schnell und leicht die richtige Einstellung zum Scharfstellen des Bildes und kann es ebenso schnell und leicht wieder für ein anderes Objekt scharfstellen.This is a quick and easy way to find the right setting to focus the image and can just as quickly and easily get it back for one focus on another object.

Die optische Achse des Fernrohrs zum Scharfstellen des Bildes, wird also mittels Augen- und Federdruck so verändert, bis die gewünschte einstellung erreicht ist0 Will man eine Einstellung festhalten, so dreht man an der Stellschraube 8 soweit, während man das Fernrohr gegen die Augen gedrückt hält, bis sie an das Mittelrohr 5 anliegt.The optical axis of the telescope for focusing the image is so changed by means of eye and spring pressure until the desired setting is reached 0 If you want to hold on to a setting, turn the adjusting screw 8 while holding the telescope against the eyes until they touch the Center tube 5 is applied.

Will man die Einstellung nicht mit dem leichten Druck gegen die Augen vornehmen, sondern von Hand, so dreht man die Stellschraube 8 gegen den Druck der Feder 1, so hin und her bis die gewünschte Einstellung erreicht ist.You don't want the setting with the light pressure on the eyes make, but by hand, so you turn the adjusting screw 8 against the pressure of the Spring 1 back and forth until the desired setting is reached.
