- the rotary joystick can be locked in position either closing or opening lines, using an additional system based on a slider (7) movable between two positions in the rotary handle (6), a retracted position in which it is embedded inside the body (23) of the handle (6), and an extended position as it appears in Figure 1 a.
- Figure 2 shows all the components of the secondary cover (2) and their functional connections.
- a toothed wheel (8) rotatably mounted in the cover (2) serves to actuate a fork (9) whose two branches (10a, 10b) have the function of pushing the lever (5) in both directions, according to the direction communicated to the joystick (6).
- the precise shape of the toothed wheel (8) and the fork (9) appears respectively in Figures 3, 4a and 4b.
- the toothed wheel (8) in fact comprises an axial projection of central appearance with a toothed portion (11) provided to cooperate with a corresponding sector (12) of the fork (9).
- the toothed wheel (8) is rotatably mounted in the secondary cover (2) so that it can describe a displacement angular limited by stops provided in the cover (2) cooperating with corresponding stops (13a) and (13b) of the toothed wheel (8).
- the fork is also rotatably mounted in the cover (2), and it comprises for this purpose a shaft (14) whose one end is inserted into a recess (15a) of the secondary cover (see Figure 2) and the another end is rotatably mounted in an orifice (15b) of a plate (17) screwed to the secondary cover (2).

- the assembly constituting the handle (6), is clipped on the toothed wheel (8), by means of the axial journal (21) inserted into an axial cylindrical housing (25) of the plate (22).
- Clipping itself is achieved by a clipping plate (26) slidable in contact with the upper surface of the plate (22), against a spring (27).
- This plate (26) has an internal profile (28) having a central notch flanked by two lateral shoulders, said profile (28) being inserted into a slot (29) disposed at the base of the cylindrical housing (25).
- This profile has a correspondence with the upper part of the axial journal (21), having two frustoconical surfaces (30a, 30b) surrounding a central promontory (31), as shown in Figure 3.
- the clipping plate (26) further comprises an outer profile (50) adapted to house a locking pin (46) whose operation is described later.
- the drive plate (22) has slots (34) cooperating with pins (35) respectively formed in the upper surface of the toothed wheel (8) and protruding from the lower surface of the plate (22). ).
- This slider can slide in a slideway (36) of the body (23) of the rotary handle (6), and it can pivot about a shaft (37) connected to two lugs (38a, 38b) protruding from the disk forming one of the body parts (23) of the rotary handle (6).
- Two springs (39a, 39b) each having a limb which bears against the body (23) of the handle (6) and a second limb resting against lateral tabs (40) of the slider (7), exert a action tending to bring the slide (7) out of its slide (36).
- the hole (41) in which the shaft (37) passes is elongated, allowing the slide (7) to move in translation within the body (23) of the rotary handle (6).
- the slide (7) also has at one of its ends a circular orifice (42) for its lockout. It is surmounted by a handling and guiding sole (43) allowing the user to move the slide between its retracted position and its deployed position.
- the slide (7) then comprises, at the other of its ends, lateral trunnions (44) (see FIG. 7) able to move in lateral slides (45) of a locking stud (46), said slides ( 45) being oriented so as not to oppose the displacement translating the slide (7) into the slideway (36) during the first phase of its movement, and to allow the pin (44) to move the locking pin (46) downwards, in particular through the orifice (47) formed in the base plate (22) towards the cover (2) when the slider (7) is in its final rotary phase.
- the locking pin (46) when the rotary handle (6) is in the open position or the manual closure of the lines, the locking pin (46) is located in the axis of the orifices (48a, 48b) (see FIG. 6). of the secondary cover (2), and can be inserted therein if the slide (7) is in its extended position. In this case, the locking pin (46) comes into abutment in contact with the heel (49) protruding from the drive plate (22). It is the springs (39a, 39b) which, recalling the slide in its deployed position when it has undergone a first translation to the right, dynamically drive the journals (44) downwards, and consequently generate an action on the locking pin (46) when in insertion position in the orifices (48a, 48b) of the secondary cover (2).
- the clipping plate (26) is provided on its external profile (50) with studs (53a, 53b) arranged in front of a surface (54) of the locking stud (46) in the deployed position of the slide (7), and which then prevent the translation of said plate (26). Any disassembly of the joystick (6) is then impossible.
- an end lug (51) of the clipping plate (26) (see FIGS. 6 and 7), accessible via a window (52) of the drive plate (22). ), allows disassembly of the joystick.
