Definitions

  • the present invention relates to a manual actuation device cooperating with an electrical switch device such as a motor circuit breaker housed in a box and fitted with a run control button and a control button stop with alternating movements.
  • an electrical switch device such as a motor circuit breaker housed in a box and fitted with a run control button and a control button stop with alternating movements.
  • Such control devices are well known and include a impulse start button and a lockable emergency stop button, these buttons having parallel axes, being associated with a wall of the cabinet and cooperating respectively with the device on and off.
  • a impulse start button and a lockable emergency stop button, these buttons having parallel axes, being associated with a wall of the cabinet and cooperating respectively with the device on and off.
  • the emergency stop button is pressed in position stop and is locked in this position, it is however possible to set the motor circuit breaker in the operating state by pressing the on button strongly of the box; such an operation is caused by deformations and tolerances that manifest themselves in the montage.
  • the document GB 1 079 012 describes a switching device, the housing of which is fitted with an on and off button which act on a mechanism trigger and reset lock.
  • This device has no layout able to prevent, when the device is housed in a cabinet, the inconvenience described above, due to complex transmission kinematics and deformations and tolerances which alter this kinematics.
  • the invention aims to avoid this drawback and aims to make inoperative actuation of the cabinet on button when the emergency stop button on the cabinet is locked in the off position.
  • the aim is therefore achieved by simple means, preferably involving for the triggerable transmission member, an abruptly triggered member, for example a toggle lever whose elbow is applied against a wall of sliding provided on a lever otherwise bearing on an erasable stop when the emergency stop button is pressed.
  • an abruptly triggered member for example a toggle lever whose elbow is applied against a wall of sliding provided on a lever otherwise bearing on an erasable stop when the emergency stop button is pressed.
  • the actuating device 10 illustrated in the figures is associated with a motor circuit breaker 11 housed in a box 12 whose front wall 13 is provided with pushbuttons with parallel axes X1 and X2, namely a pulse on button 14 and an emergency stop button 15 of the so-called punch type, for controlling, by via transmission elements described below, a control member on 16 and a stop control member 17 of the motor circuit breaker 11.
  • the members 16,17 are buttons pressed by pressure, of the rocking type as described in document EP-559 507, but which can also be of the sliding type ; these organs can take two positions by alternating movements, each remaining maintained in one or the other position, that is to say in the running state of. motor circuit breaker the on-board member 16 is pressed in and the off-member 17 is out, while that in the stop state of the motor circuit breaker the on member 16 is out and the off member 17 pressed.
  • the on button 14 of the box is connected to the member operation 16 of the motor circuit breaker via a transmission member 20 triggerable, preferably abruptly triggered; the transmission member 20 can take a normal position in which transmission to the organ is activated 16 of an impulse exerted on the button 14 and a safety position in which this transmission is disabled.
  • a security 30 which acts on the transmission member 20 so that it is put in its safety state when the emergency stop button is pressed, in order to activate the transmission when an attempt is made to force the start button 14.
  • the abruptly triggered transmission member 20 here comprises a articulated toggle lever 21 cooperating at one end 22 with a movable element of the start button 14 and at the other end 23 with a lever 24 capable of acting by thrust on the walking member 16.
  • the lever 24 can rotate around an axis Y1 orthogonal to the axes X1, X2.
  • the elbow 25 of the toggle lever 21 is applied against a sliding wall of a pivoting lever 31 which is part of the safety 30.
  • the abruptly triggered transmission member 20 can alternatively be constituted by any other transmission organ, capable of assuming a normal state active and an inactive safety state, between the start button 14 and the start member 16 of the breaker-motor.
  • the lever 31 has an approximate T shape, the core 32 of which pivots at its end 32a around an axis X3 parallel to the axes X1, X2 and the wing 33 of which carries a side the sliding wall 34 for the knee elbow and on the other side a bearing 35 normally applied against a stop 41 formed on a pivoting lever 40.
  • a weak return spring 36 which is for example a hairpin spring (see Figures 2 to 8) is associated with the lever 31 to tend to apply the wall 34 against the elbow 25 of the kneepad.
  • the lever 40 is disposed between the emergency stop button 15 and the stop member 17 of the motor circuit breaker so as to pivot around an axis Y2 parallel to or coincident with the axis Y1; it cooperates with the mobile part 15a of the button 15 by a support 42 and with the member 17 by a finger 43.
  • a return spring 44 can be associated with lever 24 assigned to actuate the button market.
  • the mobile element of the latter drives the toggle lever 21 whose elbow 25 slides on the wall 34 of the lever 31.
  • the lever 40 is in the high position (see FIG. 4) and maintains by its stop 41 the lever 31; the wall 34 being unable to move, the toggle does not does not deform and forces the lever 24 to pivot to put the walking member 16 in active position; simultaneously and under the effect of the internal lock of the motor circuit breaker, the stop member 17 is brought to its extended position, near finger 43 of the lever 40.
  • the operator lets it go up under the effect an internal spring; the button returns to its position indicated in dashes in Figure 3 and the various elements of the organs 20, 30 occupy the positions visible in FIG. 5.
