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.

Claims

1. Firearm sighting device, with an electrical illumination device that can be turned on and off by means of a switch, characterized in that 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 an armed state.

2. Sighting device according to claim 1, characterized in that 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 off the illumination device when the firearm is disabled.

3. Sighting device according to claim 1, characterized in that the switch can be activated using a non-contact method.

4. Sighting device according to claim 3, characterized in that the switch is a reed contact that can be closed by the force of a magnetic field.

5. Sighting device according to claim 3, characterized in that the switch is an electronic semiconductor switch that can be controlled by an optical, inductive, or capacitive proximity sensor and an evaluation circuit associated with this sensor.

6. Sighting device according to claim 1, characterized in that the switch can be activated by a mechanical force transfer.

7. Sighting device according to claim 1, characterized in that for the conventional attachment of the sighting device to the firearm, the switch or an activation element of this switch is located on the side of the sighting device facing the firearm.

8. Retrofit kit for a firearm sighting device, characterized in that the sighting device has an electric illumination device that can be turned on and off by means of a switch;

in that the retrofit kit contains a switch suitable for replacing a standard switch that is operated by hand separately from the firearm; and

in that the switch of the retrofit kit is embodied and arranged such that after mounting the retrofit kit in or on the sighting device, 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.

9. Retrofit kit according to claim 8, characterized in that the switch of the retrofit kit is embodied and arranged such that after mounting the retrofit kit in or on the sighting device, for the conventional attachment of the sighting device on the firearm the switch is activated mechanically to turn off the illumination device when the firearm is disabled.

10. Retrofit kit according to claim 8, characterized in that the switch of the retrofit kit can be activated using a non-contact method.

11. Retrofit kit according to claim 10, characterized in that the switch of the retrofit kit is a reed contact that can be closed by the force of a magnetic field.

12. Retrofit kit according to claim 10, characterized in that the switch is an electronic semiconductor switch that can be controlled by an optical, inductive, or capacitive proximity sensor and an evaluation circuit associated with this sensor.

13. Retrofit kit according to claim 8, characterized in that the switch of the retrofit kit can be activated by a mechanical force transfer.

14. Retrofit kit according to claim 8, characterized in that, after mounting of the retrofit kit, the switch of the retrofit kit or an activation element of this switch is located on the side of the sighting device facing the firearm for the conventional attachment of the sighting device on the firearm.
