(57) Abstract:

Usage: in the design of the monitoring devices placed on the hat. The inventive device includes a holder with one hand grip to hold the device surveillance, on the other hand is a longitudinal window that allows the holder with the surveillance device to move in a vertical plane up and down, and bend forward and backward. Holder through the bracket with the two teeth that are fixed in the grooves of the casing, crown nut is pressed into the ferrule axis with the tooth. The balls are placed simultaneously in the holes of the cage axis and in the holes of the flat semicircular rack bushings installed on the bracket base, attached to the front of the headdress of the observer. The balls are placed in four holes, forming a square with one diagonal of which is parallel to the axis of the sleeve. 3 Il.

The invention relates to placement of a surveillance device on the head-dress of the observer and can be used when driving vehicles at night during the blackout.

Known devices for placing the optical device on the headdress of the observer, nweho headdress with a single hinge, axis is located above the observer's eye. Therefore, the surveillance device can only change the direction of the optical axis of the observation device in the vertical plane, but the surveillance device may not be close or remote from the observer's eye, or moved up or down with the parallel movement of the optical axis of the observation device that is needed to account for such anthropological data of the observer, as the eye position of the observer relative to the frontal part of the head, and the depth of the eye sockets.

In the device mounting the optical device on the hat [1] installing the optical device in front of the eyes is observed by using the four screws located on the hat in the elements of the articulated parallelogram. A disadvantage of this device is that it does not allow the observer to take extra optical device from the eyes and re-install it before your eyes, making it impossible to use the bracket [1] for example, for the installation of electro-optical surveillance device on the hat of the driver of the vehicle while driving in the blackout.

The proposed device provides a means of adjustment project with bracket, mounted on criminal hat, sleeve with window and a flat semi-circular counter which is within the length of the window can be moved on the bracket base to the observer and the observer, as well as to fix the lock screw at the location of the observer position holder with grip, holding the electro-optical device, and a window in the flat part of the holder, allowing the holder within the window to move up and down, and also be tilted forwards and backwards; a ball retainer with a spring stop, the axis of which is perpendicular to the axis of the bracket base and passes through the window of the holder; holder crown nut through the bracket with two bent prongs, located on the opposite sides of the bracket, pressed against the cage axis with two cutouts, including the prongs of the staples; on the opposite side of the bracket axis is pressed cylindrical spring which is located between the two thrust sleeves, one of which is pressed against the holder axis; the force of the cylindrical spring is regulated shaped nut; ball bearing between the thrust sleeve and shaped nut prevents samootvinchivaniya thrust nut during rotation of the holder of the instrument about the axis of the clip; flat semicircular Seiki, whose diameter is greater than the thickness of the shroud axis; a holder of a surveillance device, turning about the axis of the ferrule, can rise up, removing the monitor from the eyes of the observer and down, establishing a surveillance device in front of the eyes; when turning the holder, through balls compressing coil spring moves the balls up until not coincide with balls these holes in the ferrule axis and in a flat semicircular rack bushing, fixing the position of the monitor relative to the observer's eye; in the extreme upper and lower positions of the holder with the surveillance device relative to the observer's eye a tooth on the ferrule axis rests on a ledge on a flat semicircular rack bushings located on the bracket base, preventing further movement of the observation device in the direction of the observer's eye, and further movement of the observation device up.

The proposed device is shown in Fig.1-3.

The holder 1 having on one side of the grip 2 to hold the electro-optical Priora 3, and on the other longitudinal side window 4, which allows the holder with the electro-optical device to move in a vertical plane up and down and lean forward the I to the ferrule axis with the teeth 8. The balls 9 are placed simultaneously in the holes of the cage axis 6 and the holes semicircular rack 10 axis that is installed on the bracket 11 of the base 12 attached to the front of the headdress 13 observer. The balls 9 are placed in four holes, forming a square with one diagonal of the square is parallel to the axis of the sleeve 10. The spring 14 presses the ferrule 6 axis to a semi-circular rack bushing 10. The contact force is adjusted figured nut 15. The bearing 16 reduces friction between the thrust bushing 17 and the flange of the nut 15. The sleeve 10 has a longitudinal window 18 through which passes the stud 19, screwed one side of the bracket 11 of the base 12. Nut 20 presses the sleeve 10 to the bracket 11 of the base 12. The power supply unit 21 electro-Opti - ical device 3, mounted on the back of the headdress 13, balances the electro-optical device, increasing the resistance of the provisions of the electro-optical device in front of the driver while driving the vehicle at night during the blackout. When wearing headgear for mounting the electro-optical device in front of the eyes weaken the clamping holder 1 crown nut 7 and clutching at the electro-optical device, p is the unit located before the eyes of the observer in a convenient position. After that the castle nut 7 wrap hand. If necessary to bring the electro-optical device to the eyes or to alienate him from the eyes of the observer by loosening the nut 20 moves the sleeve together with mounted on it the electro-optical device in the desired direction and avertive nut 20. For emergency discharge of the electro-optical device from the eyes of the observer, clutching at the electro-optical device, raise it up. However, due to the fact that the diameter of the balls 9 greater than the thickness of the flat semicircular rack 10 of the sleeve holder 1 together with the yoke axis 6, resting on the balls, compresses the spring 14 and moves the ball up until not coincide with the balls 9, the following holes in the holder 6 axis and in a flat semicircular rack 10. In the extreme positions of the tooth 8 of the shroud axis 6 abuts against the ledge 22 is a flat semi-circular rack 10, further limiting the movement of the electro-optical device up or down when approaching the electro-optical device to the eyes of the observer.

In the proposed device will provide reliable fixation of the electro-optical device in the working and non-working positions, as well as emergency discharge from the eye of the observer and return to the previous polynom, the sleeve and the holder, wherein the holder is equipped with a grip and a longitudinal window, and the sleeve is installed on the bracket base and equipped with a flat semi-circular stand with the two tabs located parallel to and offset from the axis of the sleeve when the holder is located on axis with the clip with the notches on opposite sides, which include the teeth of the clamps and clamped to the bracket by a nut to the other side of the cage axis through a thrust bearing adjacent cylindrical spring, and between the holder axis and a flat semicircular rack bushings with four ball, which are located in the corners of the square, one diagonal of which is parallel to the axis of the sleeve, the diameter of the balls is greater than the thickness of the shroud axis.
