Definitions

  • the invention relates to a lock for bolt with two locking catches. More particularly, the present invention relates to such a lock having a switch to indicate not only the "open” state but also the "closed” state of the lock.
  • this type of lock comprises two switches, one of the two being dedicated to provide the indication of the "open or poorly closed” state of the door and the other being dedicated to provide the indication relating to the door in the "closed" state of the door.
  • the door closed at the first lock notch of the bolt is simply equivalent to an indication "open door” given by a switch.
  • the first switch is usually located on the bolt between the first and second lock while the second switch is located on the retention pawl.
  • This type of lock has the major disadvantage of requiring two switches, which is particularly expensive. Moreover, the electrical circuit necessary for the operation of these two switches is bulky while the space available in a lock is very small.
  • Locks having a single switch are also known, as in the document US 6175202 , which discloses a lock using a single switch adapted to detect the pre-closing position, just before the retention pawl cooperates with the second bolt closing notch, to engage or stop a closing assist mechanism.
  • Another lock having a single switch is also known from US 5,785,364 which corresponds to the preamble of claim 1.
  • the problem of the locks of the state of the art using a single switch lies in the fact that they are not reliable as to the information of the state, open or closed, lock. Indeed, with a single switch, they can correctly indicate only one state of the lock, either the "open” state or the "closed” state.
  • the switch is necessarily at least switched just before or just after the second lock.
  • the invention intends to remedy the disadvantages of the devices of the prior art by proposing a lock for opening having a single switch able to indicate with certainty the "open” and "closed” state of the lock, that is to say the open position of the bolt and the closed position complete (to the second lock notch) of the bolt, thanks to a simple and effective means not requiring a complex connectivity.
  • the present invention relates to a lock for an opening according to claim 1.
  • a tab of the retaining pawl comes into contact with the holding pawl to force the latter to release the control lever, this contact intervening substantially at the moment when the tooth of the retaining pawl passes the second locking catch bolt.
  • control lever holding pawl does not switch the switch when lowering the pawl to the first locking position so that the information relating to the "closed" state of the lock will be obtained only when the tooth of the retention pawl actually cooperates with the second locking latch of the bolt.
  • the figure 1 is a schematic representation of the lock in the "open” state, the two latches not closing the latch cooperating with the retention pawl,
  • FIGS. 2a and 2b are two views of a schematic representation of the lock shown on the figure 1 in the "pre-closed” state, the tooth of the retention pawl having just passed the first latch of the bolt,
  • FIGS. 3a and 3b are two views of a schematic representation of the lock shown on the figure 1 in the "pre-closed” state, the tooth of the retention pawl being located between the first and the second locking latch of the bolt, close to the latter,
  • FIGS. 4a and 4b are two views of a schematic representation of the lock shown on the figure 1 when the top of the tooth of the retention pawl is substantially against the top of the second closing catch,
  • FIGS. 5a and 5b are two views of a schematic representation of the lock shown on the figure 1 when the tooth of the retention pawl has just passed the second locking latch of the bolt, that is to say that the lock, or the bolt, is in the "closed" state,
  • the figure 6 illustrates the state of the switch, closed (position 1) or open (position 0) of a lock according to the invention, during the opening and closing of the lock according to the position of the tooth of the pawl of retention with respect to locking notches of the bolt.
  • FIGS 1 to 5 illustrate chronologically the closing kinematics of a lock according to the invention, since the open position of the bolt 1 illustrated on the figure 1 up to the position of closure of the bolt 1 illustrated on the Figures 5a and 5b .
  • the term "closure” is used to designate the state of the lock when the tooth 2 of the retention pawl 3 cooperates with the second locking catch 4 of the bolt 1 so as to block the latter 1.
  • the opening of the lock will here be indicated by the switch 8 when the tooth 2 of the retention pawl 3 is between the first 7 and the second 4 locking notch, against the first notch closure 7 , or beyond the first notch; the tooth 2 of the retention pawl 3 can no longer cooperate with the closing notches 4, 7.
  • the lock conventionally comprises a bolt 1 having a housing 5, or recess, to accommodate a striker, not shown in the accompanying figures.
  • the bolt 1 shown in the accompanying figures comprises a circular orifice 6 defining its axis of rotation, said bolt 1 mounted in the lock being fixed, for example by means of an axis fixed to the counterplate of the lock, not shown in the figures, by
  • the bolt 1 is rotatably mounted in an XOY plane and is connected to a return spring, not shown in the accompanying figures, acting in pressure on the bolt 1 to bring it into its position. opening, in which it does not cooperate with the retaining pawl 3.
  • the direction of the force exerted by the return spring of the bolt 1 is the clockwise direction on the views of the Figures 2a , 3a , 4a and 5a presenting for example the front face of the bolt 1 and the counterclockwise direction on the views of the figures 2b , 3b , 4b and 5b presenting the rear face of the bolt 1.
  • the retention pawl 3 is also a conventional element of a lock. he comprises a tooth 2 which will come into contact or abut with the first 7 or the second 4 locking notch of the bolt 1.
  • the retention pawl 3 is rotatably mounted and rotates in a plane parallel to the plane of rotation XOY of the bolt 1.
  • the lock according to the invention also comprises a switch, or switch 8, adapted to be in an activated state and a deactivated state, characteristic of the "open” or “closed” state of the lock, this switch 8 comprises a pin plunger 18 axially slidable to occupy a protruding position out of the switch 8 and a position retracted into the switch 8, its two positions of the plunger pin 18 marking the two states on / off of the switch 8 corresponding to the two states open / closed bolt 1 or lock.
  • the teat-plunger 18 is slidably mounted in a conduit of the switch 8 and has a spring or the like, not shown in the accompanying figures, acting in pressure on said pin-plunger 18 to bring it into its protruding position out of the switch 8. Arbitrarily, it was chosen here to consider that the protruding position of the plunger nipple 18 would mean the closed state of the lock while the retracted position of the plunger nipple 18 indicate the open state of the lock.
  • the control lever 9, also called probe, has the function of cooperating with the switch 8, via its contact with its pin-plunger 18, to position it in its two states.
  • the contact between the control lever 9 and the switch 8 is thus achieved via a pin-plunger 18, said pin-plunger 18 being movable between a protruding position out of the switch 8 and a position retracted into said switch 8.
  • the bolt 1, the retention pawl 3, the switch 8 and the control lever 9 are conventional elements of a lock and have no particular characteristic. Moreover, the respective functions of these different elements 1, 3 and 8 are identical in the present invention to those they have in the locks of the state of the art.
  • the retention pawl 3 has a tab 10 intended to come into contact or abutment with the holding pawl 11 of the control lever 9 so that the holding pawl 11 releases the control lever 9.
  • This tab 10 extends perpendicularly to the plane of rotation XOY of the bolt 1 and retention pawl 3.
  • the lock according to the present invention is characterized in that it comprises a mechanical means comprising a holding ratchet of the control lever adapted to hold the control lever in position, the holding of the control lever in position preventing the change of the first to second state of the switch.
  • a mechanical means comprising a holding ratchet of the control lever adapted to hold the control lever in position, the holding of the control lever in position preventing the change of the first to second state of the switch.
  • the control lever 9, or probe here comprises a substantially rectangular portion 12 intended to come to contact the switch 8 when the control lever 9 is in its rest position.
  • the control lever 9 further comprises a protruding portion 13 in the shape of a beak.
  • Lever 9 is rotatably mounted and is rotatable perpendicular to the plane of rotation XOY of the bolt 1 and the retention pawl 3, from its rest position to its end position, when the lock is closed, where the control lever 9 comes in abutment against a sidewall 14 of the bolt 1.
  • a spring, or pressure means acts on the control lever 9 to bring it to its extreme position.
  • control lever 9 is rotatable in a plane perpendicular to the plane of rotation XOY of the bolt 1. This allows in particular that the portion 13 of the control lever 9 comes into contact with a side of the bolt 1 so that this last 1, when opening the lock, returns the control lever 9 from its extreme position to its rest position.
  • the mechanical means chosen to illustrate the invention here consists of a holding pawl 11 formed by a circular ring 15 comprising two levers 16, 17. These two levers 16, 17 extend from the circumference of the ring 15, symmetrically. on both sides of said ring 15. As can be seen on the Figures 2 to 4 , the holding pawl 11, via one of the two levers 16, prevents the control lever 9 from tilting and thus switching the switch 8.
  • the retaining pawl 11 is rotatable in a parallel plane, and shifted, to the XOY plane rotation of the bolt 1 and the retention pawl 3.
  • the holding pawl 11 is located at proximity of the bolt 1 and the retaining pawl 3 on one side of the XOY plane.
  • the bolt 1 is in the open position, the tooth 2 of the retaining pawl 3 and the locking notches 4, 7 of the bolt 1 not cooperating, the control lever 9 is in its rest position, that is, that is to say that the control lever 9 presses the plunger 18.
  • the protruding portion 13 of the control lever 9 is simply based on a face 19 of the bolt 1, the retaining pawl 11 of the control lever 9 is not active, that is to say it is not necessary that the retaining pawl 11 maintains the control lever 9, the latter 9 already occupying its rest position.
  • the holding pawl 11, or more exactly one of its two levers is placed under the control lever 9, plus exactly under the protruding portion 13 of said control lever 9, to maintain it in its rest position.
  • the control lever 9 under the effect of its spring, switch to its extreme position. Indeed, during the rotation of the bolt 1 to its closed position, the control lever 9 is no longer supported by one of the faces of the bolt 1, because of the particular geometry of a conventional bolt so that the holding pawl 11 takes over and keeps the control lever 9 in its rest position, the switch 8 is not switched.
  • the retaining pawl 11 holds the control lever 9 during the entire path of the tooth 2 of the retention pawl 3 between the first 7 and the second 4 locking notch of the bolt 1.
  • the control lever 9 is held in its position resting until the passage of the tooth 2 of the retention pawl 3 beyond the top of the second locking notch 4, when the tooth 2 retention pawl 3 abuts against the second closing notch 4 to lock the bolt 1 in its closed position.
  • the holding pawl 11 still maintains the control lever 9 in the rest position when the top of the tooth 2 of the retention pawl 3 is substantially opposite the top of the second locking catch 4.
  • the control lever 9 actuates the switch 8 so that the switch 8 is in the closed position.
  • This closed position of the switch 8 is maintained as the tooth 2 of the retention pawl 3 has not passed the second closure 4, that is to say that the bolt 1 is in the closed position.
  • the control lever 9 no longer actuates the switch 8 so that the switch 8 is in the open position.
  • the opening kinematics of the lock, or bolt 1, not shown in the accompanying figures, consists of raising, or tilting, the control lever 9 from its extreme position to its rest position.
  • the control lever 9 In its extreme position, illustrated on the Figures 5a and 5b , occupied when the bolt 1 is in the closed position, the control lever 9 abuts against a sidewall 14 of the bolt 1 so that when the bolt 1, under the effect of its return spring, starts to turn back from its closed position to its open position, the bolt 1 drives the control lever 9 and forces it to return to its rest position.
  • the protruding portion 13 of the control lever 9 tilts under the driving action of the bolt 1 and comes to rest on the face 18 of the bolt 1.
  • the control lever 9 actuates the switch 8 so that the plunger 18 of the switch 8 is depressed.
  • the figure 6 highlights when the switch 8 changes state (0 or 1) to indicate the closing or opening of the lock.
  • the figure 6 allows to illustrate the specific characteristic of the lock according to the invention, namely the fact that the change of state of the switch 8, indicating the open / closed state of the lock, does not take place at the same time, or more exactly at the same relative position of the tooth 2 of the retention pawl 3 with respect to the closing catches 4, 7 of the bolt 1, when the lock is opened and when it is closed.
  • the switch 8 indicates the open state of the lock when the tooth 2 of the retention pawl 3 passes between the first 7 and the second 4 locking notch of the bolt 1 (and before the closed state ) but when the lock is closed, the switch 8 indicates the closed state only when the tooth 2 of the retention pawl 3 cooperates with the second closing catch 4, that is to say when the tooth 2 of the retention pawl 3 blocks the second locking catch 4 of the bolt 1.
  • the control lever 9 is held by the retaining pawl 11 thus only when the lock is closed.
  • the tooth 2 of the retention pawl 3 like the second locking notch 4 of the bolt 1, have a shape of V, the vertices of these two elements 4 and 2 being oriented towards one another. It is only when one of the faces of the tooth 2 of the retention pawl 3 is placed against one of the faces of the second locking latch 4, blocking the bolt 1, by rotation of the retention pawl 3, that the lug 10 of the retention pawl 3 pushes the retaining pawl 11, by its portion 17, releasing the control lever 9 which tilts. The tilting of the control lever 9 releases the plunger stud 18 of the switch 8, causing the change of state of said switch 8 which then indicates the open state of the lock.
