Description

Binoculars with a camera

The present innovation relates to a binocular telescope with a camera, which takes photographs with the same magnification, as it has the binoculars, enables.

With known Pernrohren it is not possible to reach far away Photographing objects and cameras with an attachable telephoto lens, with which distant objects can be recorded, have a large weight of 300 - 3000 g.

It is the task of the innovation, a compact and lightweight binoculars to create with a camera. Another aim of the innovation is to create an easy-to-use double telescope.

According to the invention, this is achieved by means of a central tube-shaped one Element; a pair of tubular members rotatably disposed about the central member and the central tubular member Element serves as a fulcrum; Prism elements that are

On the drawings rotatable tubular elements 1, 2 are shown, which have the central tubular element 3 as a fulcrum. Prisms 4 are arranged in the rotatable elements. From the rear ends of the rotatable elements 1, 2, eyepiece elements 5 protrude, in which eyepieces 8 are screwably mounted are. On the outer circumference of the eyepieces 8 there are knobs 9 and depressions provided so that said eyepieces can be rotated easily.

On the opposite side of the rotatable tubular elements 1, 2 projecting objective elements 10 are provided, on which the tubular elements 12 with the objective lenses 11 (as shown in FIG. 5) are mounted. These elements 12 are rotatably mounted around the element 16 containing the photolenses, which is screwably mounted in the element 3 with a thread 3 ′. Elements 12 are made in one piece with an arm 13 which is axially movable together with element 16. The tubular element 14 is screw-mounted on the middle element 3 and is used for adjustment. The element 14 can be rotated by means of the knobs 15. The element 16 containing the photo lenses is mounted in the element 14 and contains the lenses 17 » 18, 19, 20. The pitch of the thread 3 ¹ between the elements 14 and 16 is ■ greater than that of the thread 14 'between the elements 14 and 3 A finder 22, which is shown in enlarged form in FIG. which corresponds to the field of view when photographing. This viewfinder 22, which is contained in at least one of the ocular elements 5, is positioned in the focus of the objective lens, as can be seen from FIGS. 5, 6 and 8. A flat fastening plate 23 is ^{fastened with screws 2 1} J (see FIG. 10) on the side of the ocular lenses, that is to say on the rear end of the element 3. The mounting plate 23 is provided with a circular hole 25 into which the rear end of the element 3 is mounted and the camera box .26 is mounted with screws 27 on the mounting plate 23. The camera box 26 is provided with a circular hole 28 into which the element 16 slidably protrudes and beyond

like in Pig. 3 and 4 shown with a closure 29 and a Iris diaphragm 30 is provided.

The handling of the described specific embodiment of the invention will now be explained. By rotating the elements 1 and 2 around the element 3, the distance between the two ocular elements 8 can be adapted to the eye distance. The device is focused on an object by turning the element 14 with the knob 15. The resulting distance when the element Ik is moved forward is shorter than that of the element 16, and the resulting distance when the element 16 is moved forward corresponds to that of the objective lens 11. This is the case because the pitch of the thread 3 'on the outside of the element 16 is greater than that of the thread I ¹ I ¹ on the outside of the element 14. Adjustments are made by moving the objective lens forwards or backwards. The 3user. 'of the device brings the lens to be photographed within the image line 21 of the viewfinder 22 and actuates the shutter 29 with a release button (not shown).

When the tubular element 16 moves forward or backward is by turning the knob 15, the position of the lenses 17-20 shifts with respect to the film surface F of the camera 26 but not relating to the objective lens 11. The camera is

so focused on the object to be photographed, if with the viewfinder is in focus. The image line 21 is provided in order to be able to recognize the image section on the film in the viewfinder »

From the above it follows that the handling of this binocular telescope with camera is not difficult. An object which can be seen in the viewfinder is projected into the camera; the element 16 is displaceable in the middle element 3 of the binoculars arranged and the camera 26 is connected to the element 16.
