  • a movable arm 170 disposed between the fixed table 105 and the inner face 106 of the door, said movable arm having at least one tab forming a return above said fixed table in the area of the scripting member 110: according to a characteristic of this new variant, the movable arm 170 can be moved by an associated actuation means between a retracted position, in which the abovementioned tab or tabs are adjacent to the edge of the fixed table 105, and a release position, in which the one or more legs are released from said fixed table and protect the scripting member 110, the latter being automatically disposed under the return of said one or more legs when the movable table is raised, which then considerably facilitates the installation of a diagram-carrying disc on said fixed table.
  • the protective stop system associated with the scripting member is no longer rigidly secured to the fixed table, but on the contrary carried by a movable member authorizing the release of said legs relative to the periphery of the fixed table.
  • the parts used to make this movable stop system should be reduced to the absolute minimum, without this affecting the efficiency of the system.
  • the movable arm 170 is advantageously mounted to pivot about an axis substantially perpendicular to the plane of the interior face 106 of the door, this axis preferably being the fixed axis 112 around which the support 111 of the scripting organ.
  • the movable arm 170 has substantially the shape of a flat U, one branch 171 of which is crossed by the pivot axis 112 of said arm, and the other branch 172 of which slides under the fixed table 105 during the movement of said arm , so as to favor the guidance thereof.
  • the movable arm 170 carries two protective tabs 140, 141, under which is housed the front portion 146 of the scripting member 110 when the movable table 107 is raised; the movable arm 170 also carries an additional tab 174 under which the outer edge of the rear portion 145 of the scripting member 110 permanently passes, which provides additional guidance of the scripting member in all the angular positions of the support 111 of this one.
  • the movable arm 170 carries two protective tabs 140, 141, under which is housed the front portion 146 of the scripting member 110 when the movable table 107 is raised; the movable arm 170 also carries an additional tab 174 under which the outer edge of the rear portion 145 of the scripting member 110 permanently passes, which provides additional guidance of the scripting member in all the angular positions of the support 111 of this one.
  • FIG. 8 there is only a partial distinction between the rear portion 145 of the scripting member, but the views of FIGS.
  • this function is performed by the scripting member 110 itself, which directly drives said movable arm when the movable table 107 is raised.
  • the slide 117 pivots the support for the scripting member 111 from its writing position to a partial release position corresponding to the illustration in FIG. 9.
  • the front portion of the scripting member is housed under the protective tabs 140, 141. It is then that begins, when we continue to raise the movable table 107, a new additional release phase, here performed by direct drive.
  • the scripting member rotates the movable arm 170 against the action of the spring 173, until one reaches the position illustrated in Figure 11.
  • this new release position it is easy to see that the access to the upper face of the fixed table 105 is practically total, so that the operator can set up a diagram-carrying disc without risk of catching the scripting member, and without having to carry out an insertion from the periphery of it in a space of very low height.
  • the movable table 107 is then folded down, which brings the various elements first into the position of FIG. 9, then into the recording position in which the scripting member has still rotated toward the center of the disc.
  • a stop system is advantageously provided, here illustrated by a lug 184 of the fixed table 105, and a homologous tab 185 projecting from the periphery of said movable table.
  • the movable table 107 also has, as in the context of the device of the previous variant, a peripheral notch 142 dimensioned in such a way that passage is possible for the upper part 115 of the support for the scripting member when said movable table is folded: this allows for direct contact between the scripting member 110 and the movable table 107 in the folded position thereof.
  • a locking member making it possible to keep the movable table 107 open when the movable arm 170 is in the extended position, and when the scripting member 110 has reached a release position in which it is located at -beyond the periphery provided for the chart disc.
  • This function is here provided by a locking member 176, illustrated with a slight lateral offset in Figure 1 so as not to complicate the understanding thereof.
  • the locking member 176 is preferably disposed between the fixed table 105 and the inner face 106 of the door, and it is designed so as to be able to cooperate with the elongated slider 117, so that the locking takes place automatically when said slider has reached a position corresponding to a predetermined degree of opening of the movable table 107.
  • the locking member 176 is mounted oscillating around an axis substantially parallel to the inner face 106 of the door ; this axis is represented here by two lateral pins 177 which can be clipped under two tabs (not shown) projecting from the underside of the fixed table 105.
  • the locking member thus has a rear portion 180 cooperating with a flange 181 with a lateral extension 183 of the elongated slide 117, and a front portion 178 the end of which is opposite an associated notch 179 formed in the fixed table 105.
  • a spring 182 provided for constantly recalling the locking member 176 to a latching position with the lateral extension 183 of the slide 117.
  • FIG. 12 makes it possible to better distinguish the zone of the locking member 176. It will be noted in particular the presence of a groove 190 provided on the underside of the fixed table 105, making it possible to receive part of the rim 181 when the locking member 176 is not in the latching position.
  • the lateral extension 183 of the slide 117 slides under the rear portion 180 of the locking member 176: this corresponds for example to the position illustrated in FIG. 9.
  • the slide back 117 makes it possible to reach the snap point at which the rim 181 of the locking member suddenly switches to the stop position under the action of the spring 182: this corresponds to the position illustrated in FIG. 11.
  • this function is fulfilled by a torsion spring 187, housed in a notch 186 of the rear extension 109, and acting at the hinge of the movable table 107, for example according to a cooperation with the pinion 116 coaxial with the axis of said movable table.
  • this cooperation is illustrated by a notch 188 formed in the periphery of the pinion 116, notch receiving a branch of the torsion spring 187.
  • This notch is also visible in FIG. 10, which illustrates the articulation zone when the movable table 107 is in the raised position.
  • This writing device again allows a particularly precise recording mode by means of a scripting member arranged between two diagram-carrying discs, which are perfectly fixed and centered, without the risk of a relative sliding which would introduce an error in the interpretation. recordings.
