[0023] On the cylinder-shaped two-segment offset 4 for the base 1, there is mounted the lower end of a metal sleeve-shaped handpiece 9 having on its side surface a vertically positioned rectangular pass-through slot 10 and coaxially and horizontally positioned mounting holes 11 and 11', with a pass-through hole 12 arranged above the hole 11', whereas the handpiece 9 between the holes 11, 11' and 12 has on its outer sleeve-shaped side surface evenly spaced and vertically arranged trapezoid-shaped grooves 13 so that the control handle can be easily held by hand. In the vertically positioned slot 10 for the handpiece 9, there is mounted a profile plate-shaped lever 14 having a triangle-like profile in the side view, the lower end of said lever being fitted with an inwardly facing, diagonally arranged, rectangular lower offset 15 with its rounded end and a pass-through mounting hole 16 made therein, whereas the upper end of the lever 14 is also provided with an inwardly facing upper U-shaped offset 17 with magnet M1 mounted therein, wherein the offset 17 is fitted loosely to a pin 18 push fitted into an upper hole 12 of the handpiece 9, whereas, above the lower offset 15, the lever 14 is also provided with an inwardly facing cylinder-shaped offset 19. The lower offset 15 for the lever 14 is pivotally connected to the sleeve-shaped handpiece 9 and connected to the two-segment offset 4 using a pin 20 mounted in the hole 16 of the offset 15 for said lever and partially in the holes 7 and 7' of both segments 6 and 6' of the offset 4, wherein, onto the threaded ends of the pin 20, there are screwed mounting nuts 20' that are also partially mounted in the holes 7 and 7' of both segments 6 and 6' of the offset 4 and in the holes 11, 11' of the handpiece 9. Whereas the offset 19 for the lever 14 is fitted with a cylinder-shaped spring 21 with its end adjacent to the inner surface of the sleeve-shaped handpiece 9.

[0025] Both said offsets 26 and 26' of the housing 22 are mounted inside the upper end of the sleeve-shaped handpiece 9 so that the lower face of the ring-shaped offset 24 is adjacent to the upper face of said handpiece; and in the pass-through hole 28 of the offset 26' and in the blind hole 29 of the offset 26, there is mounted the pin 18 that connects said handpiece to the housing 22. Whereas, above the bottom 25 and in the circumferential recess 25' of the sleeve-shaped housing 22, there is mounted an electronic board 32 with a microprocessor (not shown in the drawing), said board 32 having a profile encoder 33 and three Hall sensors H1, H2 and H3 soldered thereto, wherein the Hall sensors H2 and H3 are arranged on the upper surface of said board 32 on both sides of the encoder 33 in its front part, and the third Hall sensor H1 is soldered to the lower surface of said board in its back part and detects the magnetic field generated by magnet M1 of the inner offset 17 for the lever 14 when the control handle operator presses said lever 14. The board 32, together with electronic elements arranged thereon, is covered from the top by a two-stage sleeve-shaped lid 34 fitted in the upper part of its side surface with a circumferential groove 34' (larger in diameter). In the upper face of the lid 34, there are positioned two opposing round pass-through holes 35 and 35' having cylinder-shaped compression springs 36 and 36' mounted thereon with metal balls 37 and 37' mounted on their upper faces. On the lid 34, there is provided a sleeve-shaped knurled knob 38 with an upper bottom 39 whose inner surface has a vertically positioned coaxial sleeve-shaped offset 40 with an upper end of the profile encoder 33 fitted therein, whereas the side surface of said knob 38 has along its perimeter and every 90° four threaded mounting holes 41 for screws 42 with their inner ends mounted in the groove 34' of the lid 34, thereby stabilising the position of the knob 38.

[0026] Moreover, thirty-two blind holes 43 are arranged on the inner surface of the bottom 39 of the knurled knob 38, evenly spaced on a circle with a diameter adjusted to the spacing of the holes 35 and 35' of the lid 34, for the metal balls 37 and 37' of the springs 36 and 36', thereby enabling step changes in the position of the knob 38.

[0027] Whereas, in the side surface of the ring-shaped offset 24 of the housing 22, there are provided, next to the Hall sensors H2 and H3 of the board 32, two rectangular sockets 44 and 44' with bistable slide function switches 45 and 45' with an inner channel 46 mounted thereon, said channel 46 being fitted with magnets M2 and M3 whose magnetic field is detected by said sensors when the operator of the control handle changes the position of the function switches 45 and 45'.

[0028] Electric wires (not shown in the drawing) for electronic elements of the board 32 are led out of said board 32 and led out of the control handle through the holes 31, 31", 8 and 3, said wires being connected to the central electronics system of the vehicle (not shown in the drawing) that receives and processes control signals, including the signal from the electronics system of the control handle.

[0029] In another exemplary embodiment (not shown in the drawing), in the bottom 39 of the knurled knob 38, there were provided eight or sixteen blind holes 43 for the metal balls 37 and 37' of the springs 36 and 36', wherein the number of said holes 43 was adapted to the type of the encoder 33'; moreover, the control handle had only one socket 44 with the function switch 45 fitted with M2 magnet and its board 32 was equipped with only one Hall sensor H2; whereas in the holes 7 and 7' of both segments 6, 6' of the offset 4 for the base 1, in the holes 11 and 11' of the lower end of the handpiece 9 and in the hole 16 of the inner offset 15 for the lever 14, there is push fitted the longitudinal pin 20.

[0030] The plate-shaped base 1 of the control handle according to the present invention is fastened to a hull 48 of an underwater vehicle 49 by means of screws 47 arranged in the corner holes 2 of said base, wherein, in the front part of the hull, two control handles are preferably mounted symmetrically to the longitudinal axis of the underwater vehicle 49 (as shown in Fig. 9), whereupon the electric wires (not shown in the drawing) are connected to the central electronics system of the underwater vehicle 49.

[0031] In order to start engines 50 of the underwater vehicle 49, the lever 14 of the control lever is pressed such that its magnet M1 is moved into the area covered by the Hall sensor H1 that sends a signal to the central electronics system of the underwater vehicle 49, whereupon the knurled knob 38 of said control handle that controls both engines 50 of the underwater vehicle 49 is turned to select the appropriate gear (from 0 to 9) of the engines 50, and, if the gear is set to 0 (neutral), the engines 50 do not start independently of the signals from any other systems that control and support the operation of said engines 50. The position of the knurled knob 38 is read by the encoder 33 that transmits the signal to the central electronics system of the underwater vehicle 49. Whereas, when one of the bistable function switches 45 or 45' of the housing 22 is moved, magnet M2 or M3 is moved into the area covered by the Hall sensor H2 or H3 that transmits the signal to the central electronics system of the underwater vehicle 49 to stop the vehicle and engage the reverse gear. When the bistable function switches 45 and 45' are moved again, the engines 50 accelerate until the preset speed of the knurled knob 38 is reached.

[0032] In the case where the vehicle is equipped with two control handles, the knurled knob 38 of the second control handle is used for vehicle trimming, i.e. weight distribution (vehicle balancing), such that the vehicle can be appropriately positioned on the water surface and controlled by changing its trimming angle. Whereas the second bistable function switches 45 or 45' can be freely programmed as appropriate, e.g. so as to maintain a constant speed of the underwater vehicle 49.
