  • Patent number: 8091466
    Abstract: The invention relates to a breech for a repeating rifle with a lock guide, a bolt head arranged in the lock guide, a locking sleeve arranged concentrically with the bolt head with several locking elements that can be moved by an expansion device between an inner unlocked position and an outer locked position, and a locking lever that is arranged in the lock guide and that can be activated by means of a bolt handle with which is associated a first cam element that is arranged so that it can rotate in the lock guide with a rear contact surface for support against a fixed control element. To allow especially smooth-running and safe locking action, a second cam element, which can rotate independently of the first cam element and that has a rear control cam for support against the fixed control element is associated with the locking lever.

  • Patent number: 7644530
    Abstract: For a firearm sighting device with an electrical illumination device that can be turned on and off by means of a switch, the switch is embodied and arranged in or on the sighting device such that, for the conventional attachment of the sighting device on the firearm, the switch is activated mechanically to turn on the illumination device by the activation of an actuator provided in or on the firearm for setting the firearm into the armed state. By disabling the firearm, the switch is activated mechanically to turn off the illumination device. Preferably, the activation of the switch is performed using a non-contact method, for which, in particular, the configuration of the switch as a reed contact is suitable. The switch can also be part of a retrofit kit, by means of which a sighting device for a firearm can be equipped at a later time with the previously mentioned function. Here, the switch of the retrofit kit replaces a standard switch operated by hand separately from the firearm.

  • Patent number: 7434346
    Abstract: A sighting device for a firearm exhibits a display device, which is a component of a measuring device for the distance to the target and which displays this target in the field of vision of the marksman. Of the other components of the measuring device, at least one part is not arranged in or on the sighting device. The sighting device exhibits an interface, through which the components of the measuring device arranged in or on the sighting device may be connected to components of the measuring device arranged in or on the firearm in an assembly in accordance with the intended use of the sighting device on the firearm, in such a way that, as a result, collectively a measuring device in working order arises. To this end, the firearm also exhibits a corresponding interface as well, as one of the components of the measuring device.
