Definitions

  • the present invention relates to a rapid control device according to the preamble of claim 1.
  • the drawback of this mechanism is notably due to the fact that the angle of work, namely the angle at which the rod is coupled to the spring rod is much less than 180 °.
  • the present invention provides a rapid control device such as defined in the preamble, and having two stable locking points arranged 180 ° apart.
  • This device is characterized in that the pivoting arm and the second part are mounted respectively on two coaxial axes, and in that he is equipped with the means locking arranged to cooperate with said second part rotary to define two stable positions.
  • the pivoting arm is freely mounted on a hollow axis rigidly linked to the second rotating part.
  • the mechanical energy storage spring is preferably a spring helical. It is advantageously coupled to the pivoting arm by a coupling.
  • This coupling member is preferably a chain. Chain preferably goes through a deflection pulley, which ensures a gain of square.
  • the pins consist of two ends of a section of axis crossing the arm Swivel.
  • the first rotary part 18 is mounted on the shaft 26 of the toothed wheel 17 and has two bearing surfaces 18a and 18b, radial and diametrically opposite, which are arranged to cooperate, as stops, with a pin 27 mounted parallel to the shaft 26 on a part 28 articulated on the pivoting arm 19, and to which is fixed the free end of the chain. 20.
  • the pin 27 cooperates respectively with the bearing surface 18a when the first part 18 is in a first position illustrated in particular by Figure 1 and with the bearing surface 18b when this first rotating part 18 is in a second position illustrated in particular by FIG. 3, said rotary part 18 having undergone a rotation of 180 ° between the two positions.
  • the pin 27 is preferably formed by the end of a through axis the pivoting arm 19 and which extends on the other side of this arm, under the shape of a pin 27a arranged to cooperate with two bearing surfaces 21a and 21b of the second rotary part 21 which is integral with a hollow axis 29 on which the pivoting arm 19 can rotate.
  • This hollow axis 29 is in the form of a coaxial cylindrical part to a solid axis 29a.
  • the pivoting arm 19 can rotate freely around the axis hollow 29, and the assembly constituted by the hollow axis 29 and the second part rotary 21 is freely rotatable around the solid axis 29a which is fixed.
  • the pin 27a is in abutment against the surface support 21a of this second rotary part 21.
  • the drive mechanism 25 of the movable contact 24 has an axis 30 carrying a rocking lever 31 on which is fixed a fixed pivot axis 32 which is connected by a link 33 to a pivot axis 34 fixed eccentrically on the second rotary part 21.
  • the bearing surfaces 21a and 21b of this second rotary part 21 are arranged to cooperate respectively with a movable lock 35 carrying the dead center stops 22 and 23 and which is housed inside a housing 36.
  • a thrust spring 37 is disposed in this housing and tends to push the movable lock 35 forward in a position where the bearing surfaces 21b and 21a are respectively in support against the dead center stops 22 and 23 (see respectively Figures 1 and 3).
  • the motor 13 has been activated so as to drive the gear 17 in the direction of arrow A at an angle of 180 °.
  • the first rotary part 18 has made a rotation of 180 ° by driving the pivoting arm 19 by means of the pin 27 and by arming the spring 11 by means of the articulated part 28 and the chain 20. Therefore, the pin 27a swivels 180 ° to come to rest on the bearing surface 21 b of the second rotary part 21 after having pushed the movable lock 35 towards the inside of the housing 36, against the action of the thrust spring 37.
  • the movable contact 24 remains closed and the drive mechanism 25 remains in the same position as in FIG. 1.
  • the spring 11 is armed and the rapid control device is operational. So that this command can take place, the motor 13 must drive the toothed wheel 17 in the direction arrow A until the first rotating part 18 and, by Consequently, the pivoting arm 19 has passed their neutral point.
  • the force of the spring 11, transmitted by the chain 20 exerts a very traction powerful on the articulated part 28 and causes the pivoting arm 19 to rotate at an angle of 180 °, to the position shown in Figure 3.
  • the rotation of the pivoting arm 19 causes the rotation of the second part rotary 21 driven by the pin 27a, also integral with the pivoting arm 19.
  • the pin 27a releases the movable lock 35, which is pushed back in front of the housing 36 by the thrust spring 37.
  • the bearing surface 21a of the second rotary part 21 comes to bear against the neutral stop 23 of the movable lock 35, which has been pushed into position by the thrust spring 37 in the initial phase of the movement.
  • the 180 ° rotation of the second moving part 21 generated the displacement of the rod 33 in the direction of arrow B causing the tilting of the tilting lever 31 and the rotation of the axis 30 which causes the opening of the movable contact 24.
  • the motor 13 is controlled to drive the toothed wheel 17 in the direction indicated by arrow C, i.e. in the opposite direction to that indicated by arrow A in figure 2. This rotation of the wheel generates the rotation of 180 ° of the first rotary part 18, which has the effect of tilting 180 ° the swivel arm 19 actuated by pin 27.
  • the displacement of the articulated part 28 on the pivoting arm 19 causes the tension of the spring 11 for mechanical energy accumulation.
  • the pin 27a causes the movable lock 35 to be removed inside the housing 36, against the spring pushing force 37.
  • the other components of the device do not undergo no displacement during this phase.
  • the cycle can be repeated indefinitely by an alternative training of the motor 13 in one direction or the other.
