Description

DEVICE FOR TRIGGERING A SWITCH OR SWITCH.

  The present invention relates to a trigger device.

  setting a switch or switch for triggering

  expensive switch or switch under the influence of a mo-

  Mechanical movement so as to trigger the switch from a first state to its second state at the start of a forward movement and to effect the inverse triggering from the second state to the first state at

  start of a return movement in the opposite direction to the forward movement.

  More particularly, the present invention proposes

  to provide such a device, applicable in particular to a bot-

  tier of central locking command, for example,

  in a motor vehicle, a device in which the movement

  mechanical outward and / or return movement may have a variable or arbitrary amplitude, the tripping in one direction or the other of the switch or of the switch being nevertheless carried out at each change of direction of movement whatever the amplitude of that -this within the stroke limit

switch flipping.

  The applicant company has already proposed in a French patent application No. 2 457 366 and a request for a certificate

  addition N O 2 459 346 a central locking device

  usable for the locking of door locks

  res of a motor vehicle; this electro-mechanical device

  was relatively complicated to achieve and, therefore,

  quent, relatively expensive The plaintiff also proposed

  posed in its French patent applications N O 79 24957 and

  13642 of centralized locking devices

  The purpose of the present invention is to describe

  another interesting realization of the locking devices

  centralized nation of this type using a system

  particularly original switch release.

  The subject of the invention is therefore a device for triggering

  a switch or switch in which the inter-

  breaker or switch has an actuator, such as for example a pusher capable, when it is moved in a first direction, of triggering the switch or switch from a first state to a second state, and when it is actuated in opposite direction, to trigger the switch or switch from the second state to the first state, said device having means for actuating said actuator member, characterized in that said actuating means are movable,

  on the one hand, in a forward direction, on the other hand, in a re- direction

  turn, relative to said actuator, the amplitude of said forward and / or return movement being variable or arbitrary,

  said actuating means cooperating with said actuating body

  so as, when they move in a first forward direction, to drive the actuator member at the start of this movement to trigger the switch or switch from a first state to the second state, said actuator member remaining stationary

  in the position corresponding to this second state during the

  following this first movement, and driving said actuator in the opposite direction at the start of a return movement in the opposite direction to trigger said switch switch from a second state to the first state and then leaving the actuator stationary in the position corresponding to said first

  state during the continuation of this second return movement.

  In a particularly preferred embodiment

  rée of the invention, said actuating means act on the actuator member by means of friction means, the friction force being sufficient to make kinematically

  together with the actuator and the actuation means

  during the movement of said actuator body between its two positions

  trigger, the actuator being on the contrary

  enhanced with the organ of the actuating means when the latter continue their movement after the triggering caused by the organ actuator, the relative movement between them being effected

then in the presence of friction.

  So, for example, in one embodiment such as

  Particularly simplified, the actuator member, such as for example a pusher or an operating arm or lever of a switch or switch, is frictionally mounted in an actuating means capable, for example, of sliding or tilting around an axis. , the friction means being such that the friction contact

  between the actuator and the actuator remains main-

  regardless of the amplitude of the movement, in one direction or the other, of the actuating means relative to the actuator member.

  The actuator body, for example an information pusher

  switch, can be secured to an intermediate piece whose movement controls the movement of the pusher, said intermediate piece being friction mounted in or on a movable actuating piece, the friction force between these two pieces being greater than the force necessary to trigger the actuator from one position to the other, and the friction contact between the two parts being maintained whatever the position

  relative of the niobile actuating member with respect to the

breaker.

  Advantageously, the friction piece can be slidably mounted in or on the actuating piece, the

  friction piece which may for example have a tubular form

  air with a central passage into which frictionally penetrates a

  rod secured to the actuating part.

  In a variant of this embodiment used

  readable in particular with microswitch type switches,

  a similar intermediate piece may be provided, at the re-

  gard of the push-button of the microswitch or of the switch, of a cam surface, said intermediate piece further having at least one abutment surface arranged so that as soon as the triggering is obtained by a relative movement of the cam surface by compared to the actuator pusher of the microswitch, the intermediate part, initially driven frictionally by the actuating part, is blocked, so that the part

  actuation continues its course with a sliding of money

  tion relative to the intermediate piece which remains stationary.

  Thus, in accordance with the invention, it is possible to keep the intermediate piece immobile either by the effect of

  the actuator member itself movable between two stops in the

  breaker and secured to the intermediate piece, either by means

  one or more stop surfaces outside the interrup-

  the actuator of the latter then cooperating with the

  intermediate piece by a cam or ramp effect.

  The friction connection allowing, in a first step, the kinematic joining and, in a second step, the friction release, can comprise different

  known means Preferably, however, this link to money

  tion can be obtained between the two parts to be joined temporarily

  raire, by mounting on one of the parts an elastic element capable of causing friction of determined size

  on a friction surface of the other part Particularly

  Lierly simple, provision may be made, in accordance with the invention, for producing one of the parts in the form of a sliding rod in a recess in the other part, said rod having a transverse groove in which is housed a curved spring,

  for example, an O-ring spring which tends to expand relatively

  dial out of the throat to rub against the surface of the

  passage in which the rod slides.

  Other advantages and characteristics of the invention

  will appear on reading the following description, made to

  die and in cross section of this device at the friction means; Figure 12 shows an enlarged sectional view

  according to Figure 10 at this friction means.

  We first refer to Figures 1 to 5.

  The device described has a fixed switch 1 which can be seen in the case, this switch 1 having a vertical control rod 2 emerging at its upper part La

  control rod 2 is movable, from its position shown

  -tée on Figure 1, towards a second position in the direction of

  arrow F 1 corresponding to a triggered state of the switch.

  As seen in the drawing, the rod 2 is inserted between two parallel friction linings 3 bordering the two

  edges of a longitudinal slot 4, crossed by the rod 2, pra-

  ticked in a long actuating part 5 having for example a passage 6 at one of its ends to be made integral with a control means The linings 3 are applied against the rod 2 so as to make a friction contact with that -here This friction contact can be obtained either by

  due to the inherent elasticity of the linings 3, i.e.

  seeing elastic means tending to push these linings somewhat towards each other towards the rod 2 placed

between them.

  Assuming that the switch is, with its rod, in the position shown in FIG. 1 corresponding to a first state, it can be seen that if, in accordance with FIG. 3, the part 5 is animated with a translational movement in the direction of the arrow F1, that is to say of a forward movement, the friction between the linings 3 and the rod 2 causes the rod 2 to be brought from its position shown in FIG. 2 to its second position 2 'shown in Figure 3, causing the tripping of the switch 1 In this position 2' the rod 2 is blocked and can no longer continue to move

  in the direction of arrow Fl because it comes into its posi-

  limit stop position in the interrupter's boot

  tor 1 If the forward movement continues, as seen on

  Figure 4, in the direction of arrow Fl, the rod in its po-

  sition 2 'then remains stationary, the linings 3 sliding with

  friction with respect to the rod 2 in position 2 '.

  It is therefore understood that the movement in the direction of the arrow Fl caused the triggering of the switch from the start of the movement but that this movement can then

  continue on any amplitude, lower although

  stretched to the length of slot 4, being bothered by the new

  position of the actuator member as shown in 2 '.

  We see more particularly in Figure 4 the end of the movement going in the direction of the arrow F1 If now, as we see in Figure 5, we move in the direction of the arrow F 2 the part 5, the friction between the linings 3 and the rod in its position 2 'causes immediate drive

  from the stem by the fittings to position 2, next

  what the switch rod remains in its po-

  sition 2 while the return movement can continue until, for example, in the position shown in FIG. 1. Consequently, whatever the direction of movement, go or return, of the actuating means constituted by the part 5, and what , whatever the amplitude of its movement, we

  in any case, at the start of a movement, obtains the decen-

  in one direction or, as the case may be, in the other of the

  actuator gane 2 The stroke of part 5 must be at least equal to the stroke between position 2 and position 2 'of the

switch rod.

  It is also understood that instead of being sliding with respect to the case 1 in the direction of the arrows Fl and F 2,

  the actuator rod or stud 2 could on the contrary

  like an ordinary rocker switch button

  around an axis located in the case 1 and extending perpetually

  particularly in the plan of the figure The effect would be well understood

of the same.

  Likewise, instead of being animated by a sliding movement,

  ment in the direction of arrow Fl or F 2, it is understood that the part 5 could be moved in a tilting movement,

  for example around a fixed axis crossing the trans-

  versal 6 In this case, the actuator member 2 would then be a rod or a pusher moving along its own geometrical axis, that is to say up and down, if one

  look at figure 1, between two extreme positions.

  We now refer to Figures 6 to 9.

  In this embodiment the device according to the

  vention comprises, inside a shoemaker 7 an interrup-

  bi-stable double reverser tor schematically shown in 8 and fixed relative to the case 7 This switch 8 has a pusher 9 made integral with a connecting element 10 of a slide in the form of a sleeve It having a cylindrical internal passage 12 La posterior part of

  sleeve 11 may for example include a position tab

  13 cooperating with the underside of the boot 7.

  In the case 7 can also slide, parallel to the sliding movement of the pusher 9 and the sleeve 11, an actuating part 14 having means for fixing to a control member outside the case 7 and, inside thereof, on the one hand, a guide shoe 16 cooperating with the bottom of the boot 7, on the other hand, a friction rod 17 fully penetrating the passage 12 of the sleeve 11- when the device is in the position shown in Figure 6 in which the part 14 is

  retracted as much as possible inside the case 7.

  If we refer more particularly to Figures 11 and 12, we see that the rod 17 has, towards its free end, a circular groove 18 inside which is disposed

  a toric spring 19 which tends, spontaneously, to increase

  ter diameter Therefore, the spring 19 comes into friction contact with the inner surface of the passage 12 so that the parts 16 and It remain kinematically integral as long as the effort tending to separate them has not overcome the

  friction force of the spring 19 against the wall of the passage 12.

  If starting from the position shown in FIG. 6, the part 14 is driven, in a forward movement, in the direction of the arrow Fl, it can be seen that at the start of the movement the parts II and 14 remain united, the effort of friction of

  spring 19 being greater than the force necessary to drive

  ner pusher 9 in the direction of arrow Fl and switch

switch 8.

  If the movement in the direction of the arrow F1 then continues, the pusher 9 has reached full travel and can no longer continue, immobilizing the intermediate part 11, which does not prevent the actuating part 14 from continuing

  sa.course as seen in Figure 8, the rod 17

  smoothing inside the part or sleeve 11.

  If, then, starting from the extreme position shown in FIG. 8, the actuating part 14 is animated with a return movement in the direction of the arrow F 2, as seen in FIG. 9, the beginning of the movement causes entrainment by the rod 17 of the sleeve II since the pusher

  in this sense, switch 9 only offers resistance

  this reduced significantly less than the friction force The

  switch is then tilted back to its original position

  tial and after that the movement in the direction of arrow F 2

  of part 14 can continue up to any position

  conch, at most the position shown in Figure 6.

  We now refer to Figure 10.

  In this embodiment, the actuating part 14 remains identical to the previous embodiment and slides in the same manner in the boot-maker 7 The part 11 has, for its part, on its upper face, a double cam surface intended to cooperate with two microswitches

  reversers 20, 21 fixed relative to the shoemaker, these microrup-

  teurs being actuated by the small pushers 22, 23 verti-

  movably located on their lower faces. It can be seen that for the microswitch 20, the part II has, at the level of the cam surface, a first raised surface 24 followed by a second lowered surface 25, the surfaces 24, 25 being

joined by an inclined panel.

  Likewise, at the second microswitch, the part 11 has a first surface 26 similar to the surface 24 and a second lower surface 27 similar to the surface 25,

  the surfaces 26 and 27 being likewise separated by a pan

cline.

  The operation is as follows: starting from the posi-

  tion shown in Figure 10, if we move the part 14 in the direction of arrow Fl, the rod 17 thereof, by

  its spring 19, initially carries with it the part 11.

  Quickly, from the start of this movement, the surfaces 24 and 26 abandon the pushers 22, 23 of the microswitches, and after scrolling in front of these pushers of the inclined surfaces, the pushers 22, 23 which are now free to descend downward to tilt the microswitches, are located at the lowered surfaces 25, 27 After a certain

  time, the surface 28 of the sleeve 11 abuts against the over-

  face 29 of the bootmaker 7 and the part 11 is then prevented from following the movement of the part 14 and comes to a standstill The part 14 can continue its movement to any position Upon return, the movement of the part 14 causes the part II which is no longer blocked and inclined surfaces

  then the surfaces 24, 26 bring back the microrup pushers

  in their elevated position causing the trigger

reverse.

  Although the invention has been described in connection with a particular embodiment, it is understood that it does not

  is in no way limited and that various modalities can be brought to it

  changes in shape or material without departing from it

neither of its frame nor of its spirit.
