Description

GERMAN

Various designs and possibilities are known for target shooting with handguns to enable even at night. All of these devices basically consist of an infrared spotlight and a viewing device as well as the high-voltage supply means required to power the visor. These known constructions have two major disadvantages, which are theirs Make use in the field much more difficult, on the one hand the considerable weight (Weight of the set-up with power supply approx. 15 kg) and, on the other hand, the uncomfortable and cumbersome one High-voltage cable connection between the battery and the weapon itself.

It is already known to use a small incandescent lamp attached to the barrel of the weapon Target field illumination with visible light is used to supply from a battery fastened in or on the shaft; however, the accumulator can also be carried in a backpack-like bag. Here the incandescent lamps are operated with normal battery voltage and there is no conversion into high-voltage energy necessary. The switch of such lighting systems is on or in near the pusher.

Furthermore, it has already been proposed that a special stock be interchangeable with the normal firearm stock to be trained in such a way that the high voltage generating means for the image converter of the in it Infrared visors and a small battery are housed, with the actual infrared visor the headlight is firmly connected to the shaft and pushed onto the barrel of the weapon.

In the device according to the invention, the aforementioned disadvantages of the previously known devices are avoided. The weight of the kit according to the invention including power supply means amounts to to about 5 kg. In the construction according to the invention, in which a combination of an infrared sight and an infrared spotlight is present, the high voltage supply means are for feeding the image converter tube of the visor partly housed in the visor housing itself, partly in the headlight base. This constructive solution does not require any enlargement of the external dimensions of the visor housing. This is done between the visor housing and the lens optics or between the visor housing and the headlight used space. The basic arrangement can be seen in the schematic diagram in Fig. 1, namely, the image converter tube 1, the correction lens 2 and are located in the visor housing Rectifier 5 and capacitors 6 of the high-voltage cascade. There are those in the headlight base Transistor 3 and the oscillating transformer 4 under infrared night aiming device

Here, the voltage supplied by the battery is initially transformed to 1 kV. From the subsequent multi-stage high-voltage cascade of any number of stages, depending on the number of Cascade steps, decrease a voltage of 8 to 14 kV according to the needs of the electron optics. Due to the extremely short path between the high-voltage cascade and electron optics, there is no need practically all isolation difficulties for the voltages mentioned. This is related a significant advantage in terms of handiness of the device.

The entire infrared night target device is supplied by a 6 V battery, which is in a bag - similar to a cartridge pouch - is housed and is worn as the only part on the body. the average operating time is 2 to 3 hours. The connection between battery and weapon is, since the high-voltage generating means are built into the visor housing, with a normal low-voltage cable possible and therefore does not cause any hindrance for the wearer.

The visor itself consists of infrared-permeable optics and electron optics, with their Help it is possible to see objects on the screen that are invisible to the normal eye. The electron optics are fed from the high-voltage generating means, and the

The headlight, which is attached to the infrared visor with the help of a foot, is powered directly the 6 V battery.

Claims (1)

Patent claims: 1. Infrared night aiming device for handguns and machine guns, consisting of one Infrared visor, an infrared spotlight mounted on this and a battery, characterized in that that the entire high-voltage generating means are housed partly in the visor housing itself, partly in the headlight foot, with the high-voltage means via low-voltage cables from the battery to be carried separately be fed. 2 "Device according to claim 1, characterized in that that the high-voltage cascade for the operation of the electron optics is in the with optics and electron optics equipped visor housing is located and the transistor (3) and the Vibration transformer (4), which is used to generate an intermediate voltage of about 1 kV before the Transformation in the cascade are provided, are housed in the foot of the headlight. 1 sheet of drawings © 009 S48 / 61 6.60
