• the device comprises a resilient means for repositioning 45 towards the rest position, such as a helical or conical spring (see in particular FIGS. 1 and 5), supporting on the one hand on the lower face 33 of the handle base and on the other hand on the support base 37.
• a resilient means for repositioning 45 towards the rest position such as a helical or conical spring (see in particular FIGS. 1 and 5), supporting on the one hand on the lower face 33 of the handle base and on the other hand on the support base 37.
• the base 19 also bears on its lower face 33 at least one, preferably two actuating pistons 47, each piston being able to actuate an associated switch carried by the electric circuit 15.
• the electrical circuit 15 comprises on the one hand a printed circuit board 49 and on the other hand a flexible membrane 51 disposed on the board 49, the membrane comprising each piston 47 a contact elastic mound 53 by pressing a piston on the membrane to close an electric loop and deliver a control signal.
• the printed circuit board 49 has contact pads 55 with a pattern, for example in a serpentine pattern, of two overlapping electric tracks.
• the mounds 53 comprise inside a pellet made of metal or carbon which, when it comes into contact with an associated pad 55, ensures electrical contact between the two tracks and thus closes an electric loop and thus makes it possible to deliver a control signal.
• the problem of lighting the controller has also been addressed. This aspect of the invention can also be considered independently.
• the handle 11 is made of a light transmitting material and the printed circuit board 49 comprises a lighting means such as a light emitting diode 57, centered with respect to the axis defined by the lever 11 in position rest.
• a lighting means such as a light emitting diode 57
• light-transmitting material is meant both a transparent material and a translucent material.
• the membrane 51, the support base 37 and the handle base 19 each comprise a central opening respectively bearing the reference numerals 59.
• the spherical portion 23 of the lever 11 acts as an optical lens facilitating the coupling of the light in the lever 11 by its large opening angle which minimizes light loss.
• the right portion of the handle 11 acts as a waveguide which confines the light inside the handle until it is expelled at the end 21.
• the handle is made of plastic, in particular polycarbonate.
• plastic in particular polycarbonate.
• any other optically transparent or translucent material may be used.
• This rotary member 13 is supported by a cardan link 65 so as to connect the rotary member 13 pivotally to the control lever 11. This has the effect that when the joystick pivots in the predefined directions TX1,
• the rotary control member 13 has the general shape of a bell whose apex 67 has a passage opening 69 (FIG. 5) for the control lever 11.
• the bell-shaped member 13 is surmounted by a mechanical connection means 71 with a gripping element of the rotary member (not shown).
• the means 71 may comprise means for screwing or gluing.
• the bell portion of the member 13 has on opposite sides two small axes 73 ( Figure 2) intended to cooperate with two bearings 75 formed in a cardan ring 77.
• This ring 77 itself has two tilting axes 79 which are hooked via a clipping link to a part 81 called “carousel”, for a reason which will appear clear later in the description, and which has a circular shape.
• the carousel 81 has two bearing gantries 83 capable of receiving by simple clipping the axes 79 of the ring 77.
• the piece 81 is called “carousel” because it is carried free in rotation by the support base 37.
• the carousel 81 can therefore rotate freely with the rotary member 13 and maintains the universal joint 65 with the rotary control member 13. It is therefore easily understood that a rotational movement applied to the member 13 is transmitted via the cardan link 65 to the carousel 81, this independently of any pivoting movement that can be applied to the handle and therefore also to the body 13.
• the support base comprises on its circular periphery protrusions 83 called gadroons. It is actually part of caps so that at each gadroon, there is only one point contact between the carousel 81 and the base 37.
• the support base further comprises edges 85 for guiding and centering the carousel 81 in rotation.
• the device according to the invention is equipped with means 87 for detecting the rotational movement of the carousel 81 for holding.
• these means 87 are optical means as shown in FIG. 2.
• the means 81 for detecting the rotational movement of the carousel 81 comprise portions of screens 89 arranged in a regular manner on a circle on the lower face 91 of the carousel 81 and at least one, preferably two components 93 with a barrier of light carried by the electric circuit and arranged so that the screens can interrupt a light beam measurement.
• the scrolling of the screens in front of the cells 93 creates square signals which make it possible to measure the rotation of the carousel and thus of the rotary member 13.
• the device comprises at least two light-barrier components which are arranged in offset.
• the components 93 therefore have the shape of a fork which passes through an associated opening 95 of the membrane 51 (see FIG. 2). At this stage, the entire structure and operation of the device for the movements in TZ1 and in rotation which are completely dissociated are explained, even with respect to the pivoting movement that the lever 11 and the member 13 can make.
• This circuit 49 comprises four double switches 99 arranged in pairs on opposite sides with respect to the center of the circuit defined by the joystick and defining perpendicular axes of pivoting.
• control edge 97 co-operates with the double switches formed by contact pads 99 on the printed circuit 49 and contact mounds 100, these switches enabling the detection of a pivoting movement by means of pistons 101. It is found that these switches are identical in structure and operation to the switches formed by the mounds 53 and the contact pads 55.
• the pistons 101 are received in cross-shaped openings 103 similar to the shapes formed in the base 37 for the actuating pistons 47 of the joystick base 19. The pistons are thus slidably guided by the support base 37.
• the device 1 further comprises means for indexing the rotary movement of the rotary control member 13.
• these indexing means are made in the form of magnetic indexing means.
• the magnetic indexing means comprise a stator 105 and a rotor 107, each being in the form of a ring with alternating north and south poles.
• These rings are for example made by composite materials and obtained by a sintering or molding process.
• the stator 105 is fixed in the cover 7 of the casing via a capping mechanism formed for example of lugs 109 on the ring 105 and of clipping tabs 111 made in one piece with the cover 7.
• the cover 7 further comprises means for setting position of the stator in a direction parallel to the control handle in the rest position.
• these means of implementation comprise flexible tongues 121, made in one piece with the cover 7 and having punctual support ends 123 on the stator.
• this support in three points, it is ensured that the stator is always well set up and that the distance between the stator 105 and the rotor 107 is always the same and identical over the entire circumference of the rings 105 and 107.
• the rotor 107 As for the rotor 107, it is fixed to the holding carousel 81, preferably also by clipping means, that is to say for example protuberances 113 made in one piece with the ring 107 and flexible gantry with chamfer 115.
• the device further comprises a conical spring 117 for holding in the rest position relative to a pivoting movement of the rotary member 13 and the handle 11.
• This spring 117 is supported on the one hand on the upper edge of the bell of the rotary member and on the other hand on retaining means carried by the rotor.
• These retaining means are made in one piece with the rotor and preferably comprise lugs 119.
• the device has many advantages. Among these advantages, there is mentioned in particular a good dissociation at the mechanical level of the various types of control movements that are pivotal movements, support or rotation which allows a clear and pleasant haptic for the user.
