    Device for adjusting the braking force of a trackball or trackball and associated control ball
    The general field of the invention is that of control balls, also known as "trackballs". These devices are used to control a graphics cursor on one or more display screens. It is thus possible to select and / or modify a display unit, a display window or a displayed parameter. The more particular field of the invention is that of trackballs used in aircraft cockpits.
    The cockpits of modern aircraft include a visualization system comprising several display screens. The control and modification of the information displayed is done by means of different man-machine interfaces. The trackball is one of its interfaces. It consists mainly of a trackball whose upper part is accessible to the user. The lower part is based on motion sensors which can be of different types and which detect rotations of the ball in two perpendicular directions. The sensor information is used to move a graphic cursor on a display screen.
    In aeronautical applications, the control ball is subjected, during certain phases of flight, to vibrations or accelerations that can be high. Also, it is not possible to let it spin freely. It must be braked to prevent any parasitic movement during these critical phases. This adjustment is difficult insofar as the ball must be sufficiently braked to not be sensitive to vibration but the rotation must remain flexible enough for a user to turn the ball without significant effort.
    Currently, the adjustment of the brake is ensured by a mounting shown in FIG. 1. A ring 2 comprising a flexible seal 3 is fixed on the body 4 of the device which comprises the control ball 1. This ring surrounds the upper part of the ball of ordered. The braking force of the flexible seal is provided by shims 5 arranged between the lower part of the ring 2 and the body 4. It is symbolized by the two inclined white arrows of Figure 1. This solution has two disadvantages. It is complex to implement. Moreover, in operation, the braking forces increase gradually. This hardening is due to a fouling of the various mechanical elements such as the axes, the rings, the bearings, linked to an intensive use on plane. Eventually, the trackball must be removed, dismantled and cleaned.
    The device according to the invention does not have these disadvantages. Indeed, it allows easy adjustment without having to disassemble or change or clean mechanical parts. More specifically, the subject of the invention is a device for adjusting the braking force of a trackball or "trackball" ball, characterized in that it comprises: a rotating ring in the form of a straight circular hollow cylinder; said ring comprising a flexible annular braking joint, the outer periphery of the cylinder comprising: a first oblong inclined at an angle of a few degrees with respect to the base of the cylinder; a first plurality of identical notches perpendicular to said base of the cylinder, the inside diameter of the hollow cylinder being of a diameter greater than that of the control ball and the inside diameter of the annular seal being smaller than that of the control ball; - A fixed support comprising: - a circular recess of diameter equal to that of the outer periphery of the cylinder; - A fixed pin and an indexing finger arranged so that, the ring being mounted in the recess of the fixed support, the fixed pin is housed in the oblong of the ring and the indexing finger in one of the notches of the ring, the rotation of the ring causing the displacement of the pin in the oblong, the change of indexed notch and a translational movement of the ring parallel to the axis of revolution of the cylinder.
    Advantageously, the hollow cylinder of the ring comprises at least a second oblong identical to the first oblong and a second plurality of notches identical to the first plurality of notches.
    Advantageously, the outer periphery of the cylinder comprises a handle of the ring.
    Advantageously, the fixed support has markings for identifying the position of the operating lever.
    Advantageously, the outer periphery of the cylinder comprises at the entrance of the oblong a slot for entering the rotating ring in the support.
    Advantageously, the support comprises means for closing the slot so as to avoid any withdrawal of the rotating ring mounted in its support.
    Advantageously, said control ball device comprises a device for adjusting the braking force of said ball according to one of the preceding claims. The invention will be better understood and other advantages will become apparent on reading the description which follows given by way of non-limiting example and by virtue of the appended figures among which:
    Figure 1 shows the mounting of a control ball according to the prior art;
    FIG. 2 represents the technical principle of the device for adjusting the braking force of a control ball according to the invention;
    FIG. 3 represents an exploded front view of a device for adjusting the braking force of a control ball according to the invention;
    Figure 4 shows a sectional view of the rotating ring;
    Figure 5 shows a front view of the previous adjustment device, once assembled.
    FIG. 2 represents the technical principle of the device for adjusting the braking force of a control ball according to the invention. To obtain the desired force on the control ball, the ring 2 comprising the flexible seal 3 is no longer fixed on the support but is mechanically adjustable in height as indicated by the white double arrows of FIG. user raises the ring in its support, the pressure exerted by the seal on the ball decreases and this pressure increases in the opposite case. This provision has three main advantages. The first is a considerable reduction in the adjustment and assembly time of the trackball. The second advantage is the ability to adjust the adjustment effort without dismantling by the end user. Finally, it ensures a longer life of the trackball insofar as, when the ball fouls, it can reduce the effort required for rotation by a simple movement of the ring.
    There are different mechanical means to ensure the translation of the ring. However, this translation has a number of characteristics. Its amplitude is small, of the order of a millimeter. We must therefore ensure the adjustment with great precision. The position of the ring must also be maintained when the user rotates the trackball. Finally, the adjustment must be done simply by the user.
    The device for adjusting the braking force of a control ball according to the invention fulfills these various criteria. The ring comprises mechanical means for transforming its rotation into a translational movement of small amplitude, the transformation being provided by a fixed pin sliding in a moving oblong.
    This device is shown in the exploded front view of FIG. 3. This comprises a rotating ring 20, a control ball 10 and a support 30 shown in partial section.
    The rotating ring 20 is in the form of a straight circular hollow cylinder. The ring 20 is surmounted by an annular joint 21 of flexible braking. It comprises a circular shoulder 22. This shoulder has an operating lever 27. The outer periphery 23 of the cylinder comprises: a first oblong 24 inclined at an angle of a few degrees with respect to the base of the cylinder. The lower this angle, the greater the rotation of the ring must be to cause its displacement in rotation; a first plurality of identical notches 25 perpendicular to said base of the cylinder.
    The inner diameter of the hollow cylinder is of greater diameter than that of the control ball and the inner diameter of the annular seal is smaller than that of the control ball. The outer periphery of the cylinder comprises at the entrance to the oblong 24 a slot or loophole 26 for entering the rotating ring into the support 30. This slot may comprise closure means to prevent unintentional removal of the ring in its support.
    The fixed support 30 comprises: - a circular recess 31 of diameter equal to that of the outer periphery of the cylinder; a fixed pin 32 and an indexing finger 33; - markings to identify the position of the operating lever 27.
    Figure 4 shows a sectional view of the rotating ring 20. It comprises the notches 25 and the slot 26. The shape of the notches allows to adjust the force required to move from one notch to another. The deeper the notches, the more the jump of the screen requires a big force. The interval between two notches determines the sensitivity of the braking force adjusting device. The number of notches determines the number of possible positions of the ring and its rotational stroke.
    FIG. 5 shows the rotating ring 20 mounted in its support 30. The ring 20 is mounted in the recess 31 of the fixed support and rests on its shoulder 22. The fixed pin 32 is housed in the oblong 24 of the ring and the indexing finger 33 in one of the notches 25 of the ring.
    The rotation of the ring is provided by the operating lever 27. It causes the displacement of the pin 32 in the oblong 24, the indexed notch change and a translational movement of the ring parallel to the axis of revolution of the cylinder. The flexible seal 21 which rests on the control ball 10 then exerts a greater or lesser pressure depending on the elevation of the ring 20.
    The hollow cylinder of the ring may comprise at least a second oblong identical to the first oblong and a second plurality of notches identical to the first plurality of notches. This second set oblong-notches being arranged symmetrically with respect to the first set oblong-notches. This avoids the effects of buttressing of the ring in its support.
    The realization of the various mechanical parts of the device does not pose particular problems insofar as they do not require high precision of realization.
