A telescopic sight includes at least one main tube and a reticule with a reticule adjusting device arranged on the main tube for adjusting the reticule and an optical focusing means with a focus adjusting device arranged on the main tube for focusing the optical focusing means, characterised in that the reticule adjusting device and the focus adjusting device are arranged in the form of an integrated adjusting device, preferably in the form of an integrated adjusting turret, jointly on the main tube.

Telescopic sight

A pair of binoculars includes a compact focusing mechanism providing an open reach-through space between the body tubes of the binoculars with an enhanced area for the user to grasp and hold each body tube. The focusing mechanism further provides for adjustment of the body tube spacing without affecting focusing. The focusing mechanism includes a compact focusing knob structure situated on an outside of an articulated bridge connecting the body tubes and used for adjusting and maintaining a desired distance between the tubes. The focusing mechanism includes respective arms extending from the focusing knob to each of the body tubes, the ends of the levers riding on the inside of a conically shaped plunger coaxial with a pivot point of the bridge so that adjusting a spacing between the body tubes does not affect focusing. When positioned inwardly, the focusing knob produces a longitudinal movement of the plunger to effect focusing of both focusing elements simultaneously. When pulled out, the focusing knob causes movement of an eccentric used to radially translate a pivot point of one or both of the levers thereby effecting the position of the single focusing element and providing a diopter adjustment. If desired, a second pivoted bridge may be included, longitudinally spaced from the first bridge along the body tubes so that a substantially contiguous opening is provided for grasping of the binoculars. The binoculars may use a variety of optical components including roof prisms, Porro prisms or be configured as field glasses.

Binocular telescope

An eyepiece cover for binoculars has two cover parts (,) connected by a joint (,). By rotation around the joint (,) the cover parts (,) are adjusted to the distance between the eyepieces. The adjusted distance is fixed by the friction in the joint, whereby said friction can also be formed by a catch.

A device for adjusting the reticle of an aiming telescope has a pair of threaded spindles disposed at right angles to each other and engaging a thread in an intermediate housing on the main tube. The threaded spindles act on an inner tube with the reticle mounted movably within the main tube. The threaded spindles are connected in rotationally firm fashion with a snap-in locking device which engages snap-in recesses in the intermediate housing distributed about the threaded spindle. The index plate provided is an axially displaceable turning knob to be coupled with the snap-in locking device by positive locking.

Device for adjusting the reticle of an aiming telescope

An aiming telescope has an inner tube mounted within the main tube on the eyepiece side, e.g. with a ball-and-socket joint, for receiving an inversion system and a reticle. For adjusting the reticle, a pair of adjusting spindles disposed at right angles to each other are provided, the restoring forces being applied by a spring which is supported on the ball of the ball-and-socket joint at a distance from the center of the ball, on the one hand, and on the main tube, on the other hand.
