Definitions

  • the invention relates to a system for locking and unlocking an opening.
  • the opposite second end of the workpiece is operable to disengage the first end of the bolt lock, thereby allowing the bolt to disengage from the striker and the door to open.
  • the strike is retractably mounted in the frame to be able to return the bolt to its locking position when the door is closed.
  • This system has the disadvantage including having to change the waste to be implemented.
  • All three parts forming the locking / unlocking system is mounted on the leaf without the striker needs to be modified (standard strike, of any shape, without the strike is retractable). It is even possible to have no striker, the frame of the frame then acting strike if its height is sufficient.
  • the invention also relates to an assembly for locking and unlocking an opening which comprises at least one locking and unlocking system as briefly described above and an anti-panic bar associated with said at least one system and whose the actuation causes the passage of the locking piece from its locking position to its unlocking position.
  • the locking and unlocking assembly 10 (without the door and the frame) is illustrated in perspective on the figure 2 .
  • the anti-panic bar 16 of the assembly 10 is articulated pivotably about two half-shafts 17 which are respectively fixed to two support members 20 and 22 axis framing the bar along its dimension longitudinal. Only the half-axis 17 fixed to the axle support part 20 is represented on the figure 2 .
  • the axis support 22 is covered with a hood while the cover of the axis support 20 which is visible on the figure 1 was removed on the figure 2 for the sake of clarity of the presentation.
  • the axis support 20 is for example a generally square part.
  • the half-axis 17 of the bar 16 is secured to the part 20a (platinum) of the part 20 which extends perpendicularly to a large face of the door.
  • Part 20b parallel to the large face of the door is fixed, for example by screwing (screw holes are shown on the figure 2 ), on the door 12.
  • a part 24 called body is mounted on the axis support 20.
  • the body 24 comprises, on the one hand, a part 26 having a general gantry shape which is backed to the part 20a of the part 20 and, on the other hand two side portions 28a, 28b, which extend laterally in the lower part of the frame, on either side thereof and outwards.
  • the lateral portions 28a, 28b are fixed to the portion 20b of the axis support and serve as attachment bases for the body 24.
  • the portion 26 comprises two parallel uprights (vertical on the figure 2 ) 26a, 26b which, at the bottom, are connected to the side portions 28a, 28b and, at the top, are joined by a horizontal wall 26c.
  • the body 24 serves as mounting support for the locking and unlocking system 14 which will now be described with reference to the figures 2 and 3a-c .
  • the figure 3a illustrates the system 14 of the figure 2 in isolation, that is to say without the panic bar 16, the body 24 and the axis support 20.
  • the bolt 30 and the counter-bolt 34 are both rotatably mounted about a first pivot axis A1 parallel to the surface of the large face of the door and to the elements 20b, 28a and 28b mentioned above ( figure 2 ).
  • the axis A1 is fixed perpendicular to the two parallel uprights 26a, 26b of the gantry 26, in the lower part thereof.
  • Axis A1 is oriented vertically on the figure 1 .
  • the locking piece 32 is rotatably mounted about a second pivot axis A2 parallel to the first axis A1.
  • the axis A2 is fixed perpendicular to the two uprights 26a, 26b of the gantry 26, in the upper part thereof ( figure 2 ).
  • Separate elastic means are provided for holding, on the one hand, the bolt 30 and the counter-bolt 34 and, on the other hand, the locking piece 32 in a locked position of the system 14 (closed door) which is illustrated schematically on the figures 1 and 4a-b .
  • system 14 is shown mounted on the large face 12a of the door near one, noted 12b, of the two vertical longitudinal edges 12b, 12c (on the figure 1 ) of the door, opposite a keeper 36 attached to the frame 18.
  • the bolt 30 is a hollow part in which is housed the counter-bolt 34.
  • the bolt 30 comprises two parallel lateral arms 38 and 40 in the lower part of which the axis A1 is mounted through ( figures 2 and 3a ) perpendicular to the arms.
  • the two arms 38, 40 extend in a direction perpendicular to the axis A1 (upwards on the figures 2 and 3a ) and away from it.
  • the two arms then widen to each form an advance 42, 44 such that the arms and their respective advance extend respectively in two parallel planes.
  • Each arm and its advance have a general shape of beak or pick head in profile view ( figure 3a ) and each form a lateral amount of the bolt 30.
  • the two lateral uprights are joined on the front face by a curved (convex) end wall or face 46 which extends in arcuate form from the front free end 42a, 44a of each projection upwards up to the plumb. free rear edge 38a, 40a of each arm.
  • the profile of the end face 46 is for example a portion of a circle centered on the centering axis of the front face B1.
  • the centering axis B1 and the first axis of rotation A1 are parallel to each other but staggered so as to create a pair of forces allowing the closing of the opening when the end face 46 of the bolt comes into contact with the striker 36 and / or the frame 18 on which the striker is mounted. In closed position ( figs 4a-b ), this offset of the axes also contributes to keeping the bolt 30 in its deployed position in contact with the striker 36.
  • the design of the bolt 30 mentioned above provides a free space inside the envelope delimited by the lateral uprights 38, 42 and 40, 44 and the front wall (front face) 46.
  • This free space serves to accommodate the counter-bolt 34 visible as a whole on the figure 3e , as well as on Figures 3a, 3b and 4a .
  • the bolt 30 is open in its lower part located under the front wall 46 and under each projection 42, 44 so as to provide an opening 45 in which the counter-bolt 34 partially engages.
  • the front face of the bolt is formed by the front (outer) face of the front wall 46 and its lower edge 46a ( fig 2 ), the outer faces of the two arms 38, 40, the lower faces of the two projections 42, 44 and the opening 45.
  • the counter-bolt34 is also hollow ( fig.3e ) but it is closed on all its front face and its side faces unlike the bolt.
  • the counter-bolt 34 comprises two side walls or flanks 50 and 52, parallel to each other, in the lower part of which the axis A1 is mounted through ( figures 2 and 3a ), perpendicular to the walls.
  • the bolt 30 and the counter-bolt 34 are both mounted rotatably about the axis A1 and can rotate each about this axis independently of one another within certain limits that will be defined later.
  • the side walls 50 and 52 each have a general V shape in profile view.
  • the walls are joined at the front (at their front edge) by a front wall 54 also curved (convex).
  • This convexity allows the counter-bolt 34 to establish in the center of the front wall points of contact with the keeper 36
  • the end face 46 of the bolt 30 has a double curvature: a first curvature centered on the centering axis B1 of the figure 3c (aid in closing the opening) and a second curvature perpendicular to the first and which has the same orientation as the curvature of the counter-bolt 34.
  • the respective curvatures of the same orientation of the bolt 30 and counter-bolt 34 play the same role as that described above for the counter-bolt and allow to accept misalignment of the system 14 (during installation).
  • the points of contact with the strike are located in the center of the two parts 30 and 34 and the operation of the system 14 is therefore little disturbed.
  • the counter-bolt 34 is arranged inside the bolt 30 so as to project through the opening 45 formed in the lower part of the bolt ( figures 2 and 3a ), below a plane defined by the advances 42 and 44 and the free lower edge 46a ( fig 2 ) of the front wall 46.
  • the counter-bolt 34 thus configured has the general shape of a wheelbarrow of which one of the two arms has been removed.
  • the counter-bolt is supported on the striker 36 of the figure 4a (closed door) via its front wall 54 independently of the bolt 30 and thus serves as strike detector.
  • the counter-bolt 34 also comprises an arm 56 which extends, from the rear upper free edge of the side wall 50, towards the rear, away from this wall and in alignment thereof.
  • the arm 56 has a shape configured to form, simply and with little material, a retaining element intended to cooperate with a fastening element of the locking piece 32.
  • the arm has a wavy shape, namely curved downwards and curved upwards at its free end 56a.
  • the free end curved upwards serves as retaining element against the bolt 34.
  • the arm 56 also comprises near its base with the side wall 50, a member 56b forming a stop.
  • This element 56b protrudes laterally outwardly from the counter-bolt relative to the arm 56, (perpendicularly to the latter and to the wall 50) over a distance that is greater than the lateral spacing between the side wall 50 and the lateral amount (lateral arm 38 and advanced 42) of the bolt 30.
  • the element 56b is thus arranged in alignment with the advance 42 and therefore on its path during the rotational movement of the bolt.
  • the counter-bolt has in the lower part of its front wall 54 a dropped edge 54a which is configured to abut against the outer edge of the plate 20b ( fig 2 ) after pivoting about the axis A1 by a predetermined amplitude.
  • This arrangement makes it possible to limit the movement of the counter-bolt when it deploys (in case of opening of the door).
  • the arm 56 may alternatively be arranged on the side wall 52 (the locking piece 32 is then configured in correspondence).
  • the counter-bolt may adopt a different shape and include a centered arm and not located on one of the two flanks of the counter-bolt.
  • the arm may be replaced by a rearward extension of the side wall 50, the side wall 52 is also extended symmetrically.
  • the retaining member 56b of the arm may be replaced by another type of element or retaining member, requiring or not to modify accordingly the latching element of the locking piece 32.
  • the abutment element 56b can take another form.
  • the system 14 comprises elastic means 60 which exert on the bolt 30 and against the bolt 34 a force tending to maintain each in the deployed position, particularly in the first deployed position of the bolt of the figure 4a (system 14 locked and door closed).
  • elastic means 60 take for example the form of spiral springs 60a, 60b wound around the first axis A1 on the part of the latter disposed inside the counter-bolt 34 ( Figures 3a and 3b ).
  • a first spiral spring 60a is mounted wound on a first portion of the axis A1 and comprises a branch whose free end 60a1 bears on a portion of the inner portion of the bolt 30 ( figure 3b ) which is configured to laterally lock said free end in a housing.
  • the side walls of this housing allow to guide the free end 60a1 during subsequent movements of the bolt and counter-bolt during the opening and closing of the door.
  • a second spiral spring 60b is mounted wound on a second portion of the axis A1 (remote from the first portion longitudinally) and has a free end not shown which bears against the rear inner face of the bolt 34.
  • spiral springs 60a and 60b are joined together by a flat branch 60c in the general shape of a frame. This branch is supported on the part 20b (plate) of the shaft support part 20 ( figure 2 ).
  • the bolt 30 comprises at its upper part a so-called locking rear face 62 ( figs 3a-b ) which is profiled or configured to cooperate with the locking piece 32.
  • this rear face has a concavity (visible on the figure 3c ) oriented towards the locking piece and which is centered on a centering axis coinciding with the axis A2. This configuration thus makes it possible to return the forces to which the bolt 30 is subjected on the axis A2.
  • the bolt also comprises a central projection 64 which extends from the inner wall of said bolt, away from it and beyond. beyond the rear face 62. This projection acts as a possible support for the locking piece 32.
  • the locking piece 32 is rotatably mounted about the second axis of rotation A2 which passes through the head 72 in its intermediate portion between the two parts 76 and 78.
  • the axis A2 is substantially arranged in the alignment of the vertical leg 70b of the L and is attached to two side flaps 72a, 72b of the head 72 through which it passes. This axis is rotatably mounted in the two uprights 26a, 26b ( fig 2 ).
  • Second resilient means 82 are mounted on the head and about the second axis A2 to exert on the first portion 76 of the head an elastic force tending to maintain the first portion 76 in the locking position. Given a functional clearance between the first portion 76 (free end 76a thereof) and the rear locking face 62, the locking piece is not necessarily in contact with the bolt. This arrangement makes it possible not to favor either an over-locking or an unlocking. The bolt 30 is thus locked whatever the angular position of the locking piece 32. It will be noted that the free end 76a is convex so as to match the shape of the concavity of the rear locking face 62.
  • the second portion 78 forms a lever which, under the action of a support (F), causes the pivoting of the locking piece 32 about the axis A2 as indicated by the arrows on the figures 3a and 3d .
  • the elastic means 82 take the form of two spiral springs 82a, 82b wound around the axis A2, respectively on either side of the head.
  • the two springs 82a, 82b each have a free end and are joined at their opposite end by a branch 82c which bears on the top of the first portion 76 of the head.
  • the elastic means 82 exert on the first part 76 (and thus on the locking piece 32) a force which tends to keep the free end 76a in its locking position.
  • the locking piece 32 also comprises a lateral structure 84 (laterally offset structure) which extends laterally from the horizontal branch 70a of the L towards the arm 56 of the counter-bolt 34.
  • the lateral structure 84 has an upper portion 86 which is provided with a fastening element 86a extending laterally towards the
  • the latching element 86a has a lateral extension which places it on the trajectory of the retaining element 56a of the arm 56 during the pivoting movement of the counter-bolt 34. hooking 86a and retaining 56a are thus made to cooperate as illustrated on the figure 3a during the kinematics of the different pieces that will be detailed later with reference to Figures 4a to 14 .
  • Lateral structure 84 also has a lower portion 88 whose free descending end 88a is enlarged.
  • the system 14 also comprises a third axis of rotation A3 (parallel to the axes A1 and A2) materialized by a bar 79 on which is provided a fork or crankshaft 90 for receiving the enlargement 88a ( figures 3ab and 3d -).
  • the bar 79 is bent in its central part ( 3B ) so as not to interfere with the follower 75 shown on the figure 3d .
  • the entire axis A3 / bar 79 and the fork forms a linkage element.
  • the linkage element more particularly the bar 79 has at each of its two opposite ends a member 92 such as a ball support which is intended to be connected to another linkage element (not shown here but on the Figures 18 and 19
  • the axle A3 is also mounted perpendicularly between the two lateral uprights 26a and 26b of the gantry 26 and fixed thereto ( Fig. 2 ).
  • FIGS 4a and 4b illustrate the system 14 and its mechanism in the locked position (closed door).
  • the bolt 30 is held in abutment in its first deployed position against the upper face 36a of the striker 36 via its profile-shaped beak (shoulder), under the action of the elastic means 60a.
  • the first portion 76 of the head 72 of the piece 32 is held in its position locking under the action of the resilient means 82 facing the inner rear profiled face (locking face) 62 of the bolt 30 and kept away from it by the functional game mentioned above.
  • the locking piece 32 via the end 76a of its first portion 76, thus serves as a backstop for the bolt which can not retract under the action of a force applied directly to the door (without use the panic bar 16).
  • the bolt in this position, is in its locking position.
  • the counter-bolt 34 ( Fig. 4a ) is, for its part, maintained in abutment against the side face and / or the upper edge 36b of the striker 36 under the action of the elastic means 60b.

  • the retraction of the bolt 30 during this movement passes it under the locking piece 32 ( Figs. 6 and 7 ), which prevents the latter from returning to its locking position of the figure 4a .
  • the locking piece 32 is indeed no longer solicited by the action of the user on the panic bar 16 and, subjected to the action of its elastic means 82, it tends to return to its locking position by the absence of the retracted bolt.
  • the bolt 30 and counter-bolt 34 When the door is open ( figure 9 ), the bolt 30 and counter-bolt 34 have exceeded the frame 18 of the figure 8 (it is above the bolt and counter-bolt) and are no longer constrained by the latter in their retracted position. They can then be deployed under the action of their respective resilient means 60a and 60b and occupy an extended position ( figure 9 ) which is a second extended position for the bolt and a first deployed position for the counter-bolt (this deployed position is limited by the flange 54a which abuts on the outer edge of the plate 20b.
  • the bolt 30 can not be locked in its second position deployed by the locking piece 32.
  • the bolt 30 Due to the geometry of the bolt 30 (convex front face 46), the latter gradually fades by contact of its curved end face 46 with the frame 18.
  • the contact forces between the face 46 and the frame are oriented towards axis B1 (axis of the figure 3c ).
  • the offset of the axes A1 and B1 creates a pair of forces which gradually tends to cause the bolt 30 to pivot from its extended position to its retracted position as indicated by the arrow on the Figures 10 to 12 .
  • the bolt 30 thus retracts from its second deployed position because the locking piece 32 is always retained in its unlocking position by the counter-bolt 34.
  • the positioning of the boss 56b relative to the rear face of the bolt is such that, when this rear face contacts the boss, the upper part of the end face 46 of the bolt is located under the first part 76 of the head of the locking piece 32 ( figure 11 ).
  • the locking piece 32 is thus always maintained in the unlocking position.
  • the opening force of the door and therefore the unlocking / unlocking force of the locking and unlocking system 14 is reduced compared to a conventional anti-panic bar mechanism.

Description

L'invention est relative à un système de verrouillage et de déverrouillage d'un ouvrant.The invention relates to a system for locking and unlocking an opening.

On connait du document EP 1 222 350 un système de verrouillage et de déverrouillage d'une porte qui comprend un pêne demi-tour mobile coopérant avec une gâche pour exercer une fonction de verrouillage lorsque la porte est fermée. Le pêne est maintenu en position de verrouillage contre la gâche sous l'action d'une première extrémité d'une pièce de blocage qui occupe une première position de blocage.We know of the document EP 1 222 350 a locking and unlocking system of a door which comprises a movable latch bolt cooperating with a latch to exert a locking function when the door is closed. The bolt is held in the locking position against the striker under the action of a first end of a locking piece which occupies a first locking position.

La deuxième extrémité opposée de la pièce est susceptible d'être actionnée afin de désengager la première extrémité de la pièce de blocage du pêne, permettant ainsi au pêne de se désengager de la gâche et à la porte de s'ouvrir.The opposite second end of the workpiece is operable to disengage the first end of the bolt lock, thereby allowing the bolt to disengage from the striker and the door to open.

Pour pouvoir refermer la porte, il est prévu que la gâche soit montée de façon rétractable dans l'huisserie afin de pouvoir ramener le pêne dans sa position de verrouillage lorsque la porte est refermée.To close the door, it is expected that the strike is retractably mounted in the frame to be able to return the bolt to its locking position when the door is closed.

Ce système présente comme inconvénient notamment le fait d'avoir à modifier la gâche pour pouvoir être mis en place.This system has the disadvantage including having to change the waste to be implemented.

On connait du document US 5 890 752 un système de verrouillage et de déverrouillage d'un ouvrant qui comprend un pêne et un contre pêne qui sont montés chacun sur un même axe de rotation. Il serait utile d'avoir un système de verrouillage et déverrouillage d'une porte ou, de façon plus générale d'un ouvrant, qui puisse être installé avec la porte sans avoir besoin de modifier l'environnement de la porte et notamment la gâche montée sur l'huisserie.We know of the document US 5,890,752 a locking and unlocking system of an opening which comprises a bolt and an against bolt which are each mounted on the same axis of rotation. It would be useful to have a locking and unlocking system of a door or, more generally of an opening, which can be installed with the door without having to change the environment of the door and in particular the mounted strike on the frame.

La présente invention a ainsi pour objet un système de verrouillage et de déverrouillage d'un ouvrant, le système comprenant :

  • un pêne mobile qui est apte à se déployer et à se rétracter lors de la fermeture et de l'ouverture de l'ouvrant, le pêne étant apte à occuper une première position déployée lorsque l'ouvrant est fermé et une deuxième position déployée lorsque l'ouvrant est ouvert,
  • une pièce de verrouillage mobile qui est apte à coopérer avec le pêne, dans lequel la pièce de verrouillage est conçue pour, d'une part, occuper une position de verrouillage dans laquelle elle empêche le passage du pêne de sa première position déployée à sa position rétractée en l'absence d'action extérieure sur ladite pièce et, d'autre part, passer de sa position de verrouillage à une position de déverrouillage sous l'action d'une force extérieure afin de permettre l'ouverture de l'ouvrant, le système comprenant un contre pêne mobile qui est apte à se déployer et à se rétracter lors de la fermeture et de l'ouverture de l'ouvrant, le contre pêne étant apte à empêcher le retour de la pièce de verrouillage de sa position de déverrouillage à sa position de verrouillage lorsque le pêne est dans sa deuxième position déployée et l'ouvrant est ouvert,
  • le pêne et le contre pêne sont montés chacun sur un même premier axe de rotation et sont aptes à pivoter autour de l'axe de rotation indépendamment l'un de l'autre sur une plage angulaire de rotation donnée ;
  • le pêne comprend une face frontale destinée à coopérer avec une gâche et une face arrière dite de blocage configurée pour coopérer avec la pièce de verrouillage ;
  • la face frontale du pêne présente une convexité qui est centrée sur un axe dit de centrage de la face frontale ;
  • l'axe de centrage de la face frontale et le premier axe de rotation sont décalés de manière à créer un couple de forces permettant la fermeture de l'ouvrant lorsque la face frontale du pêne entre en contact avec la gâche et/ou l'huisserie sur laquelle la gâche est montée.
The present invention thus relates to a system for locking and unlocking an opening, the system comprising:
  • a movable bolt which is able to deploy and retract during the closing and opening of the opening, the bolt being adapted to occupy a first deployed position when the door is closed and a second position deployed when the opening is open,
  • a movable locking piece which is adapted to cooperate with the bolt, wherein the locking piece is designed to, on the one hand, occupy a locking position in which it prevents the passage of the bolt from its first deployed position to its retracted position in the absence of external action on said part and, secondly, from its locking position to an unlocking position under the action of an external force to allow the opening of the opening, the system comprising a mobile against bolt which is adapted to deploy and retract during closing and opening of the opening, the against bolt being able to prevent the return of the locking piece from its unlocking position to its locking position when the bolt is in its second extended position and the opening is open,
  • the bolt and the against bolt are each mounted on the same first axis of rotation and are pivotable about the axis of rotation independently of one another over a given angular range of rotation;
  • the bolt comprises a front face intended to cooperate with a keeper and a so-called rear locking face configured to cooperate with the locking piece;
  • the front face of the bolt has a convexity which is centered on a so-called centering axis of the front face;
  • the centering axis of the end face and the first axis of rotation are offset so as to create a pair of forces allowing the opening of the opening when the front face of the bolt comes into contact with the strike and / or the frame on which the strike is mounted.

L'ensemble des trois pièces formant le système de verrouillage/déverrouillage est monté sur l'ouvrant sans que la gâche n'ait besoin d'être modifiée (gâche standard, de forme quelconque, sans que la gâche soit rétractable). Il est même possible de ne pas avoir de gâche, l'huisserie du dormant faisant alors office de gâche si sa hauteur est suffisante.All three parts forming the locking / unlocking system is mounted on the leaf without the striker needs to be modified (standard strike, of any shape, without the strike is retractable). It is even possible to have no striker, the frame of the frame then acting strike if its height is sufficient.

Dès lors que l'ouvrant est en position ouverte le pêne et le contre pêne sont déployés. Le contre pêne agit en même temps sur la pièce de verrouillage afin d'empêcher qu'elle ne revienne en position de verrouillage et n'empêche la rétractation du pêne lors du mouvement de refermeture de l'ouvrant.As soon as the opening is in the open position, the bolt and the bolt are deployed. Against the bolt acts at the same time on the locking piece to prevent it from returning to the locking position and prevents the retraction of the bolt during the closing movement of the opening.

Selon d'autres caractéristiques possibles prises isolément ou en combinaison l'une avec l'autre :

  • le pêne est apte dans sa position rétractée, à empêcher le retour de la pièce de verrouillage à sa position de verrouillage ;
  • la pièce de verrouillage comporte un premier élément d'accrochage et le contre pêne comporte un deuxième élément d'accrochage ou de retenue, le premier élément d'accrochage étant placé sur la trajectoire du deuxième élément d'accrochage et apte à venir en butée contre lui lorsque le contre pêne passe de sa position rétractée à sa position déployée et que le pêne passe à sa deuxième position déployée ;
  • la pièce de verrouillage comporte une première partie apte à coopérer avec le pêne et une deuxième partie apte à recevoir une force extérieure ; la force extérieure peut être exercée d'un côté de l'ouvrant sur une barre anti-panique avec laquelle la pièce de verrouillage est amenée à coopérer ou, du côté opposé de l'ouvrant, sur un demi-ensemble (béquille) qui est relié à un fouillot avec lequel la pièce de verrouillage est amenée à coopérer ;
  • le système comprend des premiers moyens élastiques qui sont aptes à exercer sur le pêne et le contre pêne un effort élastique tendant à les maintenir en position déployée ;
  • la pièce de verrouillage est montée sur un deuxième axe de rotation parallèle au premier axe de rotation et est apte à pivoter autour du deuxième axe de rotation ;
  • le système comprend des deuxièmes moyens élastiques qui sont aptes à exercer sur la pièce de verrouillage un effort élastique tendant à la maintenir en position de verrouillage ;
  • les premiers moyens élastiques sont aptes à exercer sur le contre pêne un effort de plus grande intensité que l'effort exercé par les deuxièmes moyens élastiques ;
  • au moins l'un des deux éléments que sont le pêne et le contre pêne comporte une butée qui est placée sur la trajectoire de l'autre élément lors du mouvement de pivotement du pêne à partir d'une position déployée, la butée étant agencée pour que, d'une part, le pêne et le contre pêne pivotent indépendamment l'un de l'autre, à partir d'une position déployée, sur la plage angulaire de rotation donnée et, d'autre part, au-delà de cette plage angulaire, le pêne entre en contact avec le contre pêne par l'intermédiaire de la butée et entraine ledit contre pêne dans la poursuite du mouvement de pivotement ;
  • la face arrière de blocage présente une concavité qui est orientée vers la pièce de verrouillage et centrée sur un axe dit de centrage de la face arrière ; la face arrière ainsi profilée permet d'orienter les efforts vers l'axe de centrage ;
  • l'axe de centrage de la face arrière de blocage correspond au deuxième axe de rotation de la pièce de verrouillage ; ainsi, les efforts de blocage ne perturbent pas le comportement de la pièce de verrouillage et la position de cette dernière reste stable quels que soient les efforts appliqués sur l'ouvrant ;
  • lors du passage de sa position de verrouillage à sa position de déverrouillage et inversement, la pièce de verrouillage est apte à coopérer avec un élément de tringlerie monté rotatif autour d'un axe de rotation afin de provoquer sa rotation dans un sens ou dans le sens opposé ;
  • le pêne est creux et accueille à l'intérieur le contre-pêne, une ouverture étant pratiquée dans le pêne pour le passage du contre-pêne en vue de sa coopération avec la gâche.
According to other possible characteristics taken separately or in combination with each other:
  • the bolt is adapted in its retracted position, to prevent the return of the locking piece to its locking position;
  • the locking part comprises a first fastening element and the against bolt comprises a second fastening element or retainer, the first fastening element being placed on the path of the second fastening element and adapted to abut against him when the against bolt passes from its retracted position to its deployed position and the bolt moves to its second deployed position;
  • the locking piece comprises a first portion adapted to cooperate with the bolt and a second portion adapted to receive an external force; the external force can be exerted on one side of the opening on an anti-panic bar with which the locking piece is brought to cooperate or, on the opposite side of the opening, on a half-assembly (stand) which is connected to a follower with which the locking piece is made to cooperate;
  • the system comprises first resilient means which are capable of exerting on the bolt and the against bolt an elastic force tending to maintain them in the deployed position;
  • the locking piece is mounted on a second axis of rotation parallel to the first axis of rotation and is pivotable about the second axis of rotation;
  • the system comprises second elastic means which are able to exert on the locking member an elastic force tending to maintain it in the locking position;
  • the first elastic means are capable of exerting on the against bolt a force of greater intensity than the force exerted by the second elastic means;
  • at least one of the two elements that are the bolt and against bolt has a stop which is placed on the path of the other element during the pivoting movement of the bolt from an extended position, the stop being arranged to that, on the one hand, the bolt and counter bolt pivot independently of one another, from an extended position, on the given angular range of rotation and, secondly, beyond this angular range, the bolt comes into contact with the against bolt through the abutment and causes said bolt against in the continuation of the pivoting movement;
  • the rear locking face has a concavity which is oriented towards the locking piece and centered on a so-called centering axis of the rear face; the thus profiled rear face makes it possible to orient the forces towards the centering axis;
  • the centering axis of the locking rear face corresponds to the second axis of rotation of the locking piece; thus, the locking forces do not disturb the behavior of the locking piece and the position of the latter remains stable regardless of the forces applied to the leaf;
  • when passing from its locking position to its unlocking position and vice versa, the locking piece is adapted to cooperate with a linkage element rotatably mounted about an axis of rotation to cause its rotation in one direction or in the direction opposite;
  • the bolt is hollow and accommodates inside the counter-bolt, an opening being made in the bolt for the passage of the counter-bolt for cooperation with the strike.

L'invention a également pour objet un ensemble de verrouillage et de déverrouillage d'un ouvrant qui comprend au moins un système de verrouillage et de déverrouillage tel que brièvement exposé ci-dessus et une barre anti-panique associée audit au moins un système et dont l'actionnement provoque la passage de la pièce de verrouillage de sa position de verrouillage à sa position de déverrouillage.The invention also relates to an assembly for locking and unlocking an opening which comprises at least one locking and unlocking system as briefly described above and an anti-panic bar associated with said at least one system and whose the actuation causes the passage of the locking piece from its locking position to its unlocking position.

Selon d'autres caractéristiques possibles :

  • l'ensemble comprend plusieurs systèmes de verrouillage et de déverrouillage qui sont reliés entre eux par un mécanisme de tringlerie rotatif qui est actionné par le mouvement de rotation de l'élément de tringlerie rotatif mentionné ci-dessus ;

Comme représenté à la figure 1 et désigné par la référence générale notée 10, un ensemble de verrouillage et de déverrouillage d'un ouvrant tel qu'une porte 12 comprend :

  • un système de verrouillage et de déverrouillage 14,
  • une barre anti-panique 16 associée au système 14 et qui coopère avec ce dernier (par appui d'un utilisateur sur la barre) pour commander le déverrouillage du système 14 et donc l'ouverture de la porte 12 par rapport au dormant 18 (huisserie) qui l'encadre.
As represented in figure 1 and designated by the general reference denoted 10, a set of locking and unlocking of an opening such as a door 12 comprises:
  • a locking and unlocking system 14,
  • an anti-panic bar 16 associated with the system 14 and which cooperates with the latter (by pressing a user on the bar) to control the unlocking of the system 14 and thus the opening of the door 12 relative to the frame 18 (frame ) who frames it.

Sur la figure 1, le système 14 est en position verrouillée (donc l'ensemble 10 est verrouillé) et la porte est maintenue fermée.On the figure 1 , the system 14 is in the locked position (so the assembly 10 is locked) and the door is kept closed.

L'ensemble de verrouillage et de déverrouillage 10 (sans la porte et le dormant) est illustré en perspective sur la figure 2.The locking and unlocking assembly 10 (without the door and the frame) is illustrated in perspective on the figure 2 .

La barre anti-panique 16 de l'ensemble 10 est montée articulée à pivotement autour de deux demi-axes 17 qui sont respectivement fixés à deux pièces de support d'axe 20 et 22 encadrant la barre suivant sa dimension longitudinale. Seul le demi-axe 17 fixé à la pièce de support d'axe 20 est représenté sur la figure 2.The anti-panic bar 16 of the assembly 10 is articulated pivotably about two half-shafts 17 which are respectively fixed to two support members 20 and 22 axis framing the bar along its dimension longitudinal. Only the half-axis 17 fixed to the axle support part 20 is represented on the figure 2 .

Le support d'axe 22 est recouvert d'un capot tandis que le capot du support d'axe 20 qui est visible sur la figure 1 a été retiré sur la figure 2 par souci de clarté de l'exposé.The axis support 22 is covered with a hood while the cover of the axis support 20 which is visible on the figure 1 was removed on the figure 2 for the sake of clarity of the presentation.

Le support d'axe 20 est par exemple une pièce en forme générale d'équerre. Le demi-axe 17 de la barre 16 est assujetti à la partie 20a (platine) de la pièce 20 qui s'étend perpendiculairement à une grande face de la porte. La partie 20b parallèle à la grande face de la porte est fixée, par exemple par vissage (des trous de vissage sont représentés sur la figure 2), sur la porte 12.The axis support 20 is for example a generally square part. The half-axis 17 of the bar 16 is secured to the part 20a (platinum) of the part 20 which extends perpendicularly to a large face of the door. Part 20b parallel to the large face of the door is fixed, for example by screwing (screw holes are shown on the figure 2 ), on the door 12.

Une pièce 24 appelée corps est montée sur le support d'axe 20. Le corps 24 comprend, d'une part, une partie 26 ayant une forme générale de portique qui est adossée à la partie 20a de la pièce 20 et, d'autre part, deux parties latérales 28a, 28b, qui s'étendent latéralement en partie basse du portique, de part et d'autre de celui-ci et vers l'extérieur. Les parties latérales 28a, 28b sont fixées à la partie 20b du support d'axe et font office de socles de fixation pour le corps 24. La partie 26 comprend deux montants parallèles (verticaux sur la figure 2) 26a, 26b qui, en partie basse, sont raccordés aux parties latérales 28a, 28b et, en partie haute, sont réunis par une paroi horizontale 26c.A part 24 called body is mounted on the axis support 20. The body 24 comprises, on the one hand, a part 26 having a general gantry shape which is backed to the part 20a of the part 20 and, on the other hand two side portions 28a, 28b, which extend laterally in the lower part of the frame, on either side thereof and outwards. The lateral portions 28a, 28b are fixed to the portion 20b of the axis support and serve as attachment bases for the body 24. The portion 26 comprises two parallel uprights (vertical on the figure 2 ) 26a, 26b which, at the bottom, are connected to the side portions 28a, 28b and, at the top, are joined by a horizontal wall 26c.

Le corps 24 sert de support de fixation au système de verrouillage et de déverrouillage 14 qui va maintenant être décrit en référence aux figures 2 et 3a-c.The body 24 serves as mounting support for the locking and unlocking system 14 which will now be described with reference to the figures 2 and 3a-c .

La figure 3a illustre le système 14 de la figure 2 de façon isolée, c'est-à-dire sans la barre anti-panique 16, le corps 24 et le support d'axe 20.The figure 3a illustrates the system 14 of the figure 2 in isolation, that is to say without the panic bar 16, the body 24 and the axis support 20.

Le système 14 comprend :

  • un pêne mobile 30 qui est apte à se déployer, d'une part, dans une première position déployée lorsqu'il est dans une position de verrouillage/blocage de la porte (système 14 en position verrouillée) et, d'autre part, dans une deuxième position déployée lorsqu'il est dans une position de déverrouillage/déblocage de la porte (système 14 en position déverrouillée) et que la porte est ouverte ; le pêne est également apte à adopter une position rétractée pour ouvrir et fermer la porte ;
  • une pièce de verrouillage mobile 32 qui est apte à coopérer avec le pêne en empêchant sa rétractation (lorsque la porte est verrouillée) lors d'une tentative d'ouverture de la porte sans passer par le déverrouillage de la pièce 32 ;en l'absence de tentative d'ouverture le pêne n'est pas nécessairement en contact avec la pièce de verrouillage 32 ;
  • un contre-pêne mobile 34 qui est apte à se déployer dans une position déployée lorsque le pêne est dans sa deuxième position déployée (porte ouverte) et à adopter une position rétractée pour ouvrir et fermer la porte ; le contre-pêne est apte à coopérer avec la pièce de verrouillage lors de l'ouverture et de la fermeture de la porte.
The system 14 comprises:
  • a moveable bolt 30 which is able to deploy, on the one hand, in a first deployed position when it is in a locking / locking position of the door (system 14 in the locked position) and, on the other hand, in a second deployed position when in a position of unlocking / unlocking the door (system 14 in position unlocked) and the door is open; the bolt is also adapted to adopt a retracted position to open and close the door;
  • a movable locking piece 32 which is adapted to cooperate with the bolt by preventing its retraction (when the door is locked) during an attempt to open the door without going through the unlocking of the piece 32; in the absence attempting to open the bolt is not necessarily in contact with the locking piece 32;
  • a moveable counter-bolt 34 which is able to deploy in an extended position when the bolt is in its second deployed position (open door) and to adopt a retracted position to open and close the door; the counter-bolt is adapted to cooperate with the locking piece when opening and closing the door.

Le pêne 30 et le contre-pêne 34 sont tous deux montés à rotation autour d'un premier axe de pivotement A1 parallèle à la surface de la grande face de la porte et aux éléments 20b, 28a et 28b précités (figure 2). L'axe A1 est fixé perpendiculairement aux deux montants parallèles 26a, 26b du portique 26, en partie basse de ceux-ci. L'axe A1 est orienté verticalement sur la figure 1.The bolt 30 and the counter-bolt 34 are both rotatably mounted about a first pivot axis A1 parallel to the surface of the large face of the door and to the elements 20b, 28a and 28b mentioned above ( figure 2 ). The axis A1 is fixed perpendicular to the two parallel uprights 26a, 26b of the gantry 26, in the lower part thereof. Axis A1 is oriented vertically on the figure 1 .

La pièce de verrouillage 32 est montée à rotation autour d'un deuxième axe de pivotement A2, parallèle au premier axe A1. L'axe A2 est fixé perpendiculairement aux deux montants 26a, 26b du portique 26, en partie haute de ceux-ci (figure 2).The locking piece 32 is rotatably mounted about a second pivot axis A2 parallel to the first axis A1. The axis A2 is fixed perpendicular to the two uprights 26a, 26b of the gantry 26, in the upper part thereof ( figure 2 ).

Des moyens élastiques séparés sont prévus pour maintenir, d'une part, le pêne 30 et le contre-pêne 34 et, d'autre part, la pièce de verrouillage 32 dans une position de verrouillage du système 14 (porte fermée) qui est illustrée schématiquement sur les figures 1 et 4a-b.Separate elastic means are provided for holding, on the one hand, the bolt 30 and the counter-bolt 34 and, on the other hand, the locking piece 32 in a locked position of the system 14 (closed door) which is illustrated schematically on the figures 1 and 4a-b .

Sur ces figures, le système 14 est représenté monté sur la grande face 12a de la porte près de l'un, noté 12b, des deux bords longitudinaux verticaux 12b, 12c (sur la figure 1) de la porte, en regard d'une gâche 36 fixée à l'huisserie 18.In these figures, the system 14 is shown mounted on the large face 12a of the door near one, noted 12b, of the two vertical longitudinal edges 12b, 12c (on the figure 1 ) of the door, opposite a keeper 36 attached to the frame 18.

L'un des deux montants latéraux du pêne 30 a été retiré sur les figures 4a-b et 5 à 9 par souci de clarté. Sur la figure 4b et les figures suivantes 4b et 5 à 8 le contre-pêne 34 n'est pas représenté.One of the two side posts of the bolt 30 has been removed from the Figures 4a-b and 5 to 9 for the sake of clarity. On the figure 4b and the following figures 4b and 5 to 8 the counter-bolt 34 is not shown.

Comme représenté sur la figure 3a, le pêne 30 est une pièce creuse dans laquelle est logé le contre-pêne 34.As shown on the figure 3a , the bolt 30 is a hollow part in which is housed the counter-bolt 34.

Le pêne 30 comprend deux bras latéraux parallèles 38 et 40 en partie basse desquels l'axe A1 est monté de manière traversante (figures 2 et 3a) perpendiculairement aux bras.The bolt 30 comprises two parallel lateral arms 38 and 40 in the lower part of which the axis A1 is mounted through ( figures 2 and 3a ) perpendicular to the arms.

Les deux bras 38, 40 s'étendent dans une direction perpendiculaire à l'axe A1 (vers le haut sur les figures 2 et 3a) et en éloignement de celui-ci.The two arms 38, 40 extend in a direction perpendicular to the axis A1 (upwards on the figures 2 and 3a ) and away from it.

Les deux bras s'élargissent ensuite pour former chacun une avancée 42, 44 telle que les bras et leur avancée respective s'étendent respectivement dans deux plans parallèles.The two arms then widen to each form an advance 42, 44 such that the arms and their respective advance extend respectively in two parallel planes.

Chaque bras et son avancée ont une forme générale de bec ou de tête de pioche en vue de profil (figure 3a) et forment chacun un montant latéral du pêne 30.Each arm and its advance have a general shape of beak or pick head in profile view ( figure 3a ) and each form a lateral amount of the bolt 30.

Les deux montants latéraux sont réunis en face avant par une paroi ou face frontale 46 bombée (convexe) qui s'étend sous forme arquée depuis l'extrémité libre avant 42a, 44a de chaque avancée en remontant vers le haut jusqu'à l'aplomb du bord arrière libre 38a, 40a de chaque bras. Comme représenté sur la figure 3c (vue de côté), le profil de la face frontale 46 est par exemple une portion de cercle centrée sur l'axe de centrage de la face frontale B1. L'axe de centrage B1 et le premier axe de rotation A1 sont parallèles entre eux mais décalés de manière à créer un couple de forces permettant la fermeture de l'ouvrant lorsque la face frontale 46 du pêne entre en contact avec la gâche 36 et/ou l'huisserie 18 sur laquelle la gâche est montée. En position fermée (figs 4a-b), ce décalage des axes contribue également à maintenir le pêne 30 dans sa position déployée en contact avec la gâche 36.The two lateral uprights are joined on the front face by a curved (convex) end wall or face 46 which extends in arcuate form from the front free end 42a, 44a of each projection upwards up to the plumb. free rear edge 38a, 40a of each arm. As shown on the figure 3c (Side view), the profile of the end face 46 is for example a portion of a circle centered on the centering axis of the front face B1. The centering axis B1 and the first axis of rotation A1 are parallel to each other but staggered so as to create a pair of forces allowing the closing of the opening when the end face 46 of the bolt comes into contact with the striker 36 and / or the frame 18 on which the striker is mounted. In closed position ( figs 4a-b ), this offset of the axes also contributes to keeping the bolt 30 in its deployed position in contact with the striker 36.

La conception du pêne 30 mentionnée ci-dessus ménage un espace libre à l'intérieur de l'enveloppe délimitée par les montants latéraux 38, 42 et 40, 44 et la paroi frontale (face avant) 46.The design of the bolt 30 mentioned above provides a free space inside the envelope delimited by the lateral uprights 38, 42 and 40, 44 and the front wall (front face) 46.

Cet espace libre sert à accueillir le contre-pêne 34 visible dans son ensemble sur la figure 3e, ainsi que sur les figures 3a, 3b et 4a.This free space serves to accommodate the counter-bolt 34 visible as a whole on the figure 3e , as well as on Figures 3a, 3b and 4a .

Le pêne 30 est ouvert dans sa partie basse située sous la paroi frontale 46 et sous chaque avancée 42, 44 de manière à ménager une ouverture 45 dans laquelle s'insère partiellement le contre-pêne 34.The bolt 30 is open in its lower part located under the front wall 46 and under each projection 42, 44 so as to provide an opening 45 in which the counter-bolt 34 partially engages.

La face avant du pêne est formée par la face (extérieure) frontale de la paroi frontale 46 et son rebord inférieur 46a (fig 2), les faces extérieures des deux bras 38, 40, les faces inférieures des deux avancées 42, 44 et l'ouverture 45.The front face of the bolt is formed by the front (outer) face of the front wall 46 and its lower edge 46a ( fig 2 ), the outer faces of the two arms 38, 40, the lower faces of the two projections 42, 44 and the opening 45.

Le contre-pêne34 est également creux (fig.3e) mais il est fermé sur toute sa face avant et ses faces latérales contrairement au pêne.The counter-bolt34 is also hollow ( fig.3e ) but it is closed on all its front face and its side faces unlike the bolt.

Le contre-pêne 34 comprend deux parois latérales ou flancs 50 et 52, parallèles entre eux, en partie basse desquels l'axe A1 est monté de manière traversante (figures 2 et 3a), perpendiculairement aux parois.The counter-bolt 34 comprises two side walls or flanks 50 and 52, parallel to each other, in the lower part of which the axis A1 is mounted through ( figures 2 and 3a ), perpendicular to the walls.

Le pêne 30 et le contre-pêne 34 sont tous deux montés de manière rotative autour de l'axe A1 et peuvent pivoter chacun autour de cet axe indépendamment l'un de l'autre dans certaines limites qui seront définies plus loin.The bolt 30 and the counter-bolt 34 are both mounted rotatably about the axis A1 and can rotate each about this axis independently of one another within certain limits that will be defined later.

Comme représenté sur les figures 3a, 3e et 4a, les parois latérales 50 et 52 ont chacune une forme générale de V en vue de profil.As shown on figures 3a , 3rd and 4th , the side walls 50 and 52 each have a general V shape in profile view.

Les parois sont réunies à l'avant (au niveau de leur bord avant) par une paroi frontale 54 également bombée (convexe). Cette convexité permet au contre-pêne 34 d'établir au centre de la paroi frontale des points de contact avec la gâche 36 On notera que la face frontale 46 du pêne 30 présente une double courbure : une première courbure centrée sur l'axe de centrage B1 de la figure 3c (aide à la fermeture de l'ouvrant) et une deuxième courbure perpendiculaire à la première et qui a la même orientation que la courbure du contre-pêne 34. Les courbures respectives de même orientation du pêne 30 et du contre-pêne 34 jouent le même rôle que celui décrit ci-dessus pour le contre-pêne et permettent d'accepter des défauts d'alignement du système 14 (lors de la pose). Ainsi, même avec une pose non parfaitement alignée du système 14 (un peu en biais), les points de contact avec la gâche sont localisés au centre des deux pièces 30 et 34 et le fonctionnement du système 14 est donc peu perturbé.The walls are joined at the front (at their front edge) by a front wall 54 also curved (convex). This convexity allows the counter-bolt 34 to establish in the center of the front wall points of contact with the keeper 36 It will be noted that the end face 46 of the bolt 30 has a double curvature: a first curvature centered on the centering axis B1 of the figure 3c (aid in closing the opening) and a second curvature perpendicular to the first and which has the same orientation as the curvature of the counter-bolt 34. The respective curvatures of the same orientation of the bolt 30 and counter-bolt 34 play the same role as that described above for the counter-bolt and allow to accept misalignment of the system 14 (during installation). Thus, even with a not perfectly aligned installation of the system 14 (a little bias), the points of contact with the strike are located in the center of the two parts 30 and 34 and the operation of the system 14 is therefore little disturbed.

Le contre-pêne 34 est agencé à l'intérieur du pêne 30 de manière à faire saillie à travers l'ouverture 45 ménagée en partie basse du pêne (figures 2 et 3a), en-dessous d'un plan défini par les avancées 42 et 44 et le bord inférieur libre 46a (fig 2)de la paroi frontale 46.The counter-bolt 34 is arranged inside the bolt 30 so as to project through the opening 45 formed in the lower part of the bolt ( figures 2 and 3a ), below a plane defined by the advances 42 and 44 and the free lower edge 46a ( fig 2 ) of the front wall 46.

Le contre-pêne 34 ainsi configuré a la forme générale d'une brouette dont un des deux bras a été retiré. Le contre-pêne est en appui sur la gâche 36 de la figure 4a (porte fermée) par l'intermédiaire de sa paroi frontale 54 indépendamment du pêne 30 et fait ainsi office de détecteur de gâche.The counter-bolt 34 thus configured has the general shape of a wheelbarrow of which one of the two arms has been removed. The counter-bolt is supported on the striker 36 of the figure 4a (closed door) via its front wall 54 independently of the bolt 30 and thus serves as strike detector.

Le contre-pêne 34 comprend également un bras 56 qui s'étend, à partir du bord libre supérieur arrière de la paroi latérale 50, vers l'arrière, en éloignement de cette paroi et dans l'alignement de celle-ci.The counter-bolt 34 also comprises an arm 56 which extends, from the rear upper free edge of the side wall 50, towards the rear, away from this wall and in alignment thereof.

Le bras 56 présente une forme configurée de manière à former, simplement et avec peu de matière, un élément de retenue destiné à coopérer avec un élément d'accrochage de la pièce de verrouillage 32.The arm 56 has a shape configured to form, simply and with little material, a retaining element intended to cooperate with a fastening element of the locking piece 32.

A titre d'exemple, le bras présente une forme ondulée, à savoir incurvée vers le bas puis incurvée vers le haut au niveau de son extrémité libre 56a. L'extrémité libre recourbée vers le haut fait office d'élément de retenue du contre-pêne 34.For example, the arm has a wavy shape, namely curved downwards and curved upwards at its free end 56a. The free end curved upwards serves as retaining element against the bolt 34.

Le bras 56 comporte également à proximité de sa base avec la paroi latérale 50, un élément 56b formant butée. Cet élément 56b (bossage) fait saillie latéralement vers l'extérieur du contre-pêne par rapport au bras 56, (perpendiculairement à ce dernier et à la paroi 50) sur une distance qui est supérieure à l'écart latéral entre la paroi latérale 50 et le montant latéral (bras latéral 38 et avancée 42) du pêne 30. L'élément 56b est ainsi agencé dans l'alignement de l'avancée 42 et donc sur sa trajectoire lors du mouvement de rotation du pêne.The arm 56 also comprises near its base with the side wall 50, a member 56b forming a stop. This element 56b (boss) protrudes laterally outwardly from the counter-bolt relative to the arm 56, (perpendicularly to the latter and to the wall 50) over a distance that is greater than the lateral spacing between the side wall 50 and the lateral amount (lateral arm 38 and advanced 42) of the bolt 30. The element 56b is thus arranged in alignment with the advance 42 and therefore on its path during the rotational movement of the bolt.

On notera que le contre-pêne comporte en partie basse de sa paroi frontale 54 un bord tombé 54a qui est configuré pour venir en butée contre le bord extérieur de la platine 20b (fig 2) après avoir effectué un mouvement de pivotement autour de l'axe A1 d'une amplitude prédéterminée. Cet agencement permet de limiter le déplacement du contre-pêne lorsqu'il se déploie (en cas d'ouverture de la porte).It will be noted that the counter-bolt has in the lower part of its front wall 54 a dropped edge 54a which is configured to abut against the outer edge of the plate 20b ( fig 2 ) after pivoting about the axis A1 by a predetermined amplitude. This arrangement makes it possible to limit the movement of the counter-bolt when it deploys (in case of opening of the door).

Selon une variante, le bras 56 peut alternativement être agencé sur la paroi latérale 52 (la pièce de verrouillage 32 est alors configurée en correspondance).According to a variant, the arm 56 may alternatively be arranged on the side wall 52 (the locking piece 32 is then configured in correspondence).

Selon une autre variante non représentée la contre-pêne peut adopter une forme différente et notamment comporter un bras centré et non localisé sur un des deux flancs du contre-pêne.According to another variant not shown the counter-bolt may adopt a different shape and include a centered arm and not located on one of the two flanks of the counter-bolt.

Selon une autre variante non représentée, le bras peut être remplacé par une extension vers l'arrière de la paroi latérale 50, la paroi latérale 52 étant également étendue de façon symétrique.According to another variant not shown, the arm may be replaced by a rearward extension of the side wall 50, the side wall 52 is also extended symmetrically.

Selon une autre variante non représentée, l'élément de retenue 56b du bras peut être remplacé par un autre type d'élément ou d'organe de retenue, nécessitant ou non de modifier en conséquence l'élément d'accrochage de la pièce de verrouillage 32.According to another variant not shown, the retaining member 56b of the arm may be replaced by another type of element or retaining member, requiring or not to modify accordingly the latching element of the locking piece 32.

Selon encore une autre variante non représentée, l'élément de butée 56b peut revêtir une autre forme.According to another variant not shown, the abutment element 56b can take another form.

Comme mentionné plus haut, le système 14 comprend des moyens élastiques 60 qui exercent sur le pêne 30 et le contre-pêne 34 un effort tendant à les maintenir chacun en position déployée, notamment dans la première position déployée du pêne de la figure 4a (système 14 verrouillé et porte fermée).As mentioned above, the system 14 comprises elastic means 60 which exert on the bolt 30 and against the bolt 34 a force tending to maintain each in the deployed position, particularly in the first deployed position of the bolt of the figure 4a (system 14 locked and door closed).

Ces moyens élastiques 60 (premiers moyens élastiques) prennent par exemple la forme de ressorts en spirales 60a, 60b enroulés autour du premier axe A1 sur la partie de celui-ci disposé à l'intérieur du contre-pêne 34 (figures 3a et 3b).These elastic means 60 (first elastic means) take for example the form of spiral springs 60a, 60b wound around the first axis A1 on the part of the latter disposed inside the counter-bolt 34 ( Figures 3a and 3b ).

Un premier ressort spirale 60a est monté enroulé sur une première portion de l'axe A1 et comporte une branche dont l'extrémité libre 60a1 est en appui sur une portion de la partie intérieure du pêne 30 (figure 3b) qui est configurée pour bloquer latéralement ladite extrémité libre dans un logement. Les parois latérales de ce logement permettent de guider l'extrémité libre 60a1 lors des mouvements ultérieurs du pêne et du contre-pêne durant l'ouverture et la fermeture de la porte.A first spiral spring 60a is mounted wound on a first portion of the axis A1 and comprises a branch whose free end 60a1 bears on a portion of the inner portion of the bolt 30 ( figure 3b ) which is configured to laterally lock said free end in a housing. The side walls of this housing allow to guide the free end 60a1 during subsequent movements of the bolt and counter-bolt during the opening and closing of the door.

Un deuxième ressort spirale 60b est monté enroulé sur une deuxième portion de l'axe A1 (éloignée longitudinalement de la première portion) et comporte une extrémité libre non représentée qui vient en appui contre la face interne arrière du contre pêne 34.A second spiral spring 60b is mounted wound on a second portion of the axis A1 (remote from the first portion longitudinally) and has a free end not shown which bears against the rear inner face of the bolt 34.

Les ressorts en spirales 60a et 60b sont réunis entre eux par une branche 60c plane en forme générale de cadre. Cette branche prend appui sur la partie 20b (platine) de la pièce 20 de support d'axe (figure 2).The spiral springs 60a and 60b are joined together by a flat branch 60c in the general shape of a frame. This branch is supported on the part 20b (plate) of the shaft support part 20 ( figure 2 ).

Le pêne 30 comprend à sa partie supérieure une face arrière dite de blocage 62 (figs 3a-b) qui est profilée ou configurée pour coopérer avec la pièce de verrouillage 32. En particulier, cette face arrière présente une concavité (visible sur la figure 3c) orientée en direction de la pièce de verrouillage et qui est centrée sur un axe de centrage confondu avec l'axe A2. Cette configuration permet ainsi de renvoyer sur l'axe A2 les efforts auxquels est soumis le pêne 30. Le pêne comprend également une saillie centrale 64 qui s'étend à partir de la paroi intérieure dudit pêne, en éloignement de celle-ci et au-delà de la face arrière 62. Cette saillie fait office d'appui éventuel pour la pièce de verrouillage 32.The bolt 30 comprises at its upper part a so-called locking rear face 62 ( figs 3a-b ) which is profiled or configured to cooperate with the locking piece 32. In particular, this rear face has a concavity (visible on the figure 3c ) oriented towards the locking piece and which is centered on a centering axis coinciding with the axis A2. This configuration thus makes it possible to return the forces to which the bolt 30 is subjected on the axis A2. The bolt also comprises a central projection 64 which extends from the inner wall of said bolt, away from it and beyond. beyond the rear face 62. This projection acts as a possible support for the locking piece 32.

La pièce de verrouillage ou de blocage 32 comprend de façon générale, notamment en référence à la figure 3d :

  • une structure centrale 70 formant un corps ayant sensiblement une forme générale de L avec une branche horizontale 70a et une branche verticale 70b,
  • une structure supérieure 72 formant une tête montée à l'extrémité supérieure de la branche verticale 70b du L,
  • une structure inférieure 74 formant des jambes 74a, 74b qui s'étendent parallèlement entre elles, vers le bas, à partir de l'extrémité libre de la branche horizontale 70a du L. Les jambes prennent appui sur un fouillot 75 qui reçoit un carré (non représenté) traversant la porte dans son épaisseur de manière à déboucher sur la face (extérieure) de la porte opposée à celle portant la barre anti-panique. Le carré est activé par un demi-ensemble extérieur (béquille généralement débrayée et qui nécessite une clé pour son embrayage) disposé de l'autre côté de la porte lorsque l'utilisateur veut débloquer la porte du côté extérieur La tête 72 comporte une première partie 76 qui est apte à coopérer avec la face arrière 62 du pêne 30 et une deuxième partie 78 qui est apte à recevoir une force extérieure F (figures 3a et 3d). Cette force est transmise à la deuxième partie 78 par l'intermédiaire de la barre anti-panique 16 lorsque l'utilisateur appuie sur celle-ci.
The locking or locking part 32 generally comprises, in particular with reference to the figure 3d :
  • a central structure 70 forming a body having substantially a general shape of L with a horizontal branch 70a and a vertical branch 70b,
  • an upper structure 72 forming a head mounted at the upper end of the vertical leg 70b of the L,
  • a lower structure 74 forming legs 74a, 74b which extend parallel to each other, downwards, from the free end of the horizontal leg 70a of L. The legs rest on a follower 75 which receives a square ( not shown) through the door in its thickness so as to open on the (outer) face of the door opposite to that carrying the anti-panic bar. The square is activated by an outer half-assembly (kickstand generally disengaged and which requires a key for its clutch) arranged on the other side of the door when the user wants to unlock the door on the outside side The head 72 has a first part 76 which is able to cooperate with the rear face 62 of the bolt 30 and a second part 78 which is able to receive an external force F ( figures 3a and 3d ). This force is transmitted to the second part 78 via the panic bar 16 when the user presses it.

La pièce de verrouillage 32 est montée à rotation autour du deuxième axe de rotation A2 qui travers la tête 72 dans sa partie intermédiaire entre les deux parties 76 et 78. L'axe A2 est sensiblement agencé dans l'alignement de la branche verticale 70b du L et est fixé à deux rabats latéraux 72a, 72b de la tête 72 qu'il traverse. Cet axe est monté à rotation dans les deux montants 26a, 26b (fig 2).The locking piece 32 is rotatably mounted about the second axis of rotation A2 which passes through the head 72 in its intermediate portion between the two parts 76 and 78. The axis A2 is substantially arranged in the alignment of the vertical leg 70b of the L and is attached to two side flaps 72a, 72b of the head 72 through which it passes. This axis is rotatably mounted in the two uprights 26a, 26b ( fig 2 ).

Des deuxièmes moyens élastiques 82 sont montés sur la tête et autour du deuxième axe A2 afin d'exercer sur la première partie 76 de la tête un effort élastique tendant à maintenir la première partie 76 en position de verrouillage. Compte tenu d'un jeu fonctionnel entre la première partie 76 (extrémité libre 76a de celle-ci) et la face arrière de blocage 62, la pièce de verrouillage n'est pas nécessairement en contact avec le pêne. Cet agencement permet de ne pas favoriser soit un sur-verrouillage soit un déverrouillage. Le pêne 30 est ainsi bloqué quelle que soit la position angulaire de la pièce de verrouillage 32. On notera que l'extrémité libre 76a est convexe afin d'épouser la forme de la concavité de la face arrière de blocage 62.Second resilient means 82 are mounted on the head and about the second axis A2 to exert on the first portion 76 of the head an elastic force tending to maintain the first portion 76 in the locking position. Given a functional clearance between the first portion 76 (free end 76a thereof) and the rear locking face 62, the locking piece is not necessarily in contact with the bolt. This arrangement makes it possible not to favor either an over-locking or an unlocking. The bolt 30 is thus locked whatever the angular position of the locking piece 32. It will be noted that the free end 76a is convex so as to match the shape of the concavity of the rear locking face 62.

La deuxième partie 78 forme un levier qui, sous l'action d'un appui (F), entraine le pivotement de la pièce de verrouillage 32 autour de l'axe A2 comme indiqué par les flèches sur les figures 3a et 3d.The second portion 78 forms a lever which, under the action of a support (F), causes the pivoting of the locking piece 32 about the axis A2 as indicated by the arrows on the figures 3a and 3d .

Plus particulièrement, les moyens élastiques 82 prennent la forme de deux ressorts spirale 82a, 82b enroulés autour de l'axe A2, respectivement de part et d'autre de la tête.More particularly, the elastic means 82 take the form of two spiral springs 82a, 82b wound around the axis A2, respectively on either side of the head.

Les deux ressorts 82a, 82b présentent chacun une extrémité libre et sont réunis à leur extrémité opposée par une branche 82c qui prend appui sur le dessus de la première partie 76 de la tête. Ainsi agencés, les moyens élastiques 82 exercent sur la première partie 76 (et donc sur la pièce de verrouillage 32) un effort qui tend à maintenir l'extrémité libre 76a dans sa position de verrouillage.The two springs 82a, 82b each have a free end and are joined at their opposite end by a branch 82c which bears on the top of the first portion 76 of the head. Thus arranged, the elastic means 82 exert on the first part 76 (and thus on the locking piece 32) a force which tends to keep the free end 76a in its locking position.

La pièce de verrouillage 32 comprend également une structure latérale 84 (structure déportée latéralement) qui s'étend latéralement à partir de la branche horizontale 70a du L en direction du bras 56 du contre-pêne 34.The locking piece 32 also comprises a lateral structure 84 (laterally offset structure) which extends laterally from the horizontal branch 70a of the L towards the arm 56 of the counter-bolt 34.

La structure latérale 84 comporte une portion supérieure 86 qui est munie d'un élément d'accrochage 86a s'étendant latéralement en direction du bras 56 du contre-pêne 34. L'élément d'accrochage 86a possède une extension latérale qui le place sur la trajectoire de l'élément de retenue 56a du bras 56 lors du mouvement de pivotement du contre-pêne 34. Les deux éléments d'accrochage 86a et de retenue 56a sont ainsi amenés à coopérer comme illustré sur la figure 3a lors de la cinématique des différentes pièces qui sera détaillée plus loin en référence aux figures 4a à 14.The lateral structure 84 has an upper portion 86 which is provided with a fastening element 86a extending laterally towards the The latching element 86a has a lateral extension which places it on the trajectory of the retaining element 56a of the arm 56 during the pivoting movement of the counter-bolt 34. hooking 86a and retaining 56a are thus made to cooperate as illustrated on the figure 3a during the kinematics of the different pieces that will be detailed later with reference to Figures 4a to 14 .

La structure latérale 84 comporte également une portion inférieure 88 dont l'extrémité libre descendante 88a est élargie.Lateral structure 84 also has a lower portion 88 whose free descending end 88a is enlarged.

Le système 14 comprend également un troisième axe de rotation A3 (parallèle aux axes A1 et A2) matérialisé par une barre 79 sur laquelle est prévue une fourche ou vilebrequin 90 destiné à recevoir l'élargissement 88a (figures 3ab et 3d-). La barre 79 est coudée dans sa partie centrale (fig.3b) afin de ne pas entrer en interférence avec le fouillot 75 représenté sur la figure 3d. L'ensemble de l'axe A3/barre 79 et de la fourche forme un élément de tringlerie. L'élément de tringlerie, plus particulièrement la barre 79 comporte à chacune de ses deux extrémités opposées un organe 92 tel qu'un support boule qui est destiné à être connecté à un autre élément de tringlerie (non représenté ici mais sur les figures 18 et 19).L'axe A3 est également monté de façon perpendiculaire entre les deux montants latéraux 26a et 26b du portique 26 et fixé à ces derniers (fig. 2).The system 14 also comprises a third axis of rotation A3 (parallel to the axes A1 and A2) materialized by a bar 79 on which is provided a fork or crankshaft 90 for receiving the enlargement 88a ( figures 3ab and 3d -). The bar 79 is bent in its central part ( 3B ) so as not to interfere with the follower 75 shown on the figure 3d . The entire axis A3 / bar 79 and the fork forms a linkage element. The linkage element, more particularly the bar 79 has at each of its two opposite ends a member 92 such as a ball support which is intended to be connected to another linkage element (not shown here but on the Figures 18 and 19 The axle A3 is also mounted perpendicularly between the two lateral uprights 26a and 26b of the gantry 26 and fixed thereto ( Fig. 2 ).

On notera que dans l'exemple de réalisation de la figure 1 (version monopoint) l'axe A3 n'est pas utile. Il sera utilisé dans le mode de réalisation multi-points des figures 17 à 19.It will be noted that in the embodiment of the figure 1 (single-point version) the A3 axis is not useful. It will be used in the multi-point embodiment of Figures 17 to 19 .

On va maintenant décrire en référence aux figures 4a à 14 la cinématique de mouvement des différentes pièces constitutives du système de verrouillage et de déverrouillage 14 lors de la mise en oeuvre dudit système pour ouvrir et pour fermer la porte 12.We will now describe with reference to Figures 4a to 14 the kinematics of movement of the various components of the locking and unlocking system 14 during the implementation of said system for opening and closing the door 12.

Les figures 4a et 4b illustrent le système 14 et son mécanisme en position verrouillée (porte fermée).The Figures 4a and 4b illustrate the system 14 and its mechanism in the locked position (closed door).

Le pêne 30 est maintenu en appui dans sa première position déployée contre la face supérieure 36a de la gâche 36 par l'intermédiaire de son profil en forme de bec (épaulement), sous l'action des moyens élastiques 60a. La première partie 76 de la tête 72 de la pièce 32 est maintenue dans sa position de verrouillage sous l'action des moyens élastiques 82 en regard de la face interne arrière profilée (face de blocage) 62 du pêne 30 et maintenue écartée de celle-ci par le jeu fonctionnel mentionné ci-dessus. La pièce de verrouillage 32, par l'intermédiaire de l'extrémité 76a de sa première partie 76, fait ainsi office de butée arrière pour le pêne qui ne peut se rétracter sous l'action d'un effort appliqué directement sur la porte (sans avoir recours à la barre anti-panique 16). Le pêne, dans cette position, est dans sa position de verrouillage.The bolt 30 is held in abutment in its first deployed position against the upper face 36a of the striker 36 via its profile-shaped beak (shoulder), under the action of the elastic means 60a. The first portion 76 of the head 72 of the piece 32 is held in its position locking under the action of the resilient means 82 facing the inner rear profiled face (locking face) 62 of the bolt 30 and kept away from it by the functional game mentioned above. The locking piece 32, via the end 76a of its first portion 76, thus serves as a backstop for the bolt which can not retract under the action of a force applied directly to the door (without use the panic bar 16). The bolt, in this position, is in its locking position.

Le contre-pêne 34 (fig. 4a) est, quant à lui, maintenu en appui contre la face latérale et/ou l'arête supérieure 36b de la gâche 36 sous l'action des moyens élastiques 60b.The counter-bolt 34 ( Fig. 4a ) is, for its part, maintained in abutment against the side face and / or the upper edge 36b of the striker 36 under the action of the elastic means 60b.

Dans cette position, les éléments de retenue 56a et d'accrochage 86a respectifs du contre-pêne 34 et de la pièce d'accrochage 32 ne coopèrent pas.In this position, the retaining elements 56a and hooking 86a respectively counter-bolt 34 and the attachment piece 32 do not cooperate.

La figure 5 illustre la mise en oeuvre du déverrouillage du système 14 pour ouvrir la porte 12 (le contre-pêne et l'axe A3 n'ont pas été représentés par souci de clarté).The figure 5 illustrates the implementation of unlocking the system 14 to open the door 12 (the counter-bolt and the axis A3 have not been shown for the sake of clarity).

Pour ce faire, l'utilisateur appuie de façon conventionnelle sur la barre anti-panique 16 des figures 1 et 2, provoquant ainsi son pivotement autour du demi-axe 17 comme indiqué par la flèche notée P sur la figure 2.In order to do this, the user conventionally presses on the panic bar 16 of the Figures 1 and 2 , thereby causing it to pivot about the half-axis 17 as indicated by the arrow marked P on the figure 2 .

La deuxième partie 78 de la tête de la pièce de verrouillage 32 traverse (de façon non représentée) la paroi 20a du support d'axe et s'étend sous la barre 16 (figure 2).The second portion 78 of the head of the locking piece 32 (not shown) crosses the wall 20a of the axis support and extends under the bar 16 ( figure 2 ).

Un appui sur la barre provoque un appui F sur la deuxième partie d'appui 78 et le pivotement de la pièce de verrouillage 32 comme indiqué sur la figure 5.Pressing on the bar causes a support F on the second support portion 78 and the pivoting of the locking piece 32 as indicated on the figure 5 .

Le pivotement de la pièce de verrouillage 32 de sa position de verrouillage (figures 4a-b) à sa position de déverrouillage (figure 5) entraine le pivotement de l'axe A3 (barre 79) par l'intermédiaire de la coopération élargissement 88a - fourche 90. Ce mouvement sera utile pour le mode de réalisation de la figure 17.The pivoting of the locking piece 32 from its locking position ( Figures 4a-b ) to its unlocking position ( figure 5 ) causes the pivoting of the axis A3 (bar 79) via the widening cooperation 88a - fork 90. This movement will be useful for the embodiment of the figure 17 .

On notera que la barre anti-panique 16 vient en butée sur la platine 20a (de façon non représentée sur les figures) et cette butée détermine la position déverrouillée extrême de la pièce de verrouillage 32. Ce dispositif limiteur de course permet d'éviter que la pièce de verrouillage 32 ne soit soumise à des efforts de trop grande intensité (résultant directement de l'appui de l'utilisateur sur la barre) et donc qu'elle ne soit abîmée.Note that the anti-panic bar 16 abuts on the plate 20a (not shown in the figures) and this stop determines the extreme unlocked position of the locking piece 32. This stroke limiter device prevents that the locking piece 32 is not subjected to excessive force (resulting directly from the support of the user on the bar) and therefore it is damaged.

Le pivotement de la pièce de verrouillage 32 libère le pêne 30 mais celui-ci reste dans sa première position déployée sous l'action des moyens élastiques 60a. La porte 12 est ainsi toujours maintenue en position fermée mais devient manoeuvrable. L'utilisateur peut ainsi continuer à appuyer sur la barre anti-panique qui est en butée et transmettre un effort de poussée à la porte via les platines ou transmettre directement l'effort de poussée à la porte avec son autre main, comme illustré par la flèche sur la figure 6.The pivoting of the locking piece 32 releases the bolt 30 but it remains in its first extended position under the action of the elastic means 60a. The door 12 is thus always maintained in closed position but becomes manoeuvrable. The user can continue to press the anti-panic bar which is in abutment and transmit a thrust force to the door via the plates or directly transmit the thrust force to the door with his other hand, as illustrated by the arrow on the figure 6 .

Lorsque l'effort d'appui sur la porte est supérieur à l'effort exercé par les moyens élastiques 60a sur l'arrière du pêne 30 (effort de retenue), le pêne 30 glisse par son bec ou épaulement sur la face supérieure 36a de la gâche et s'efface ainsi progressivement en pivotant autour du premier axe A1 (fig. 6).When the bearing force on the door is greater than the force exerted by the elastic means 60a on the rear of the bolt 30 (retaining force), the bolt 30 slides by its beak or shoulder on the upper face 36a of the striker and thus erases progressively by pivoting around the first axis A1 ( Fig. 6 ).

La rétractation du pêne 30 durant ce mouvement fait passer celui-ci sous la pièce de verrouillage 32 (figs. 6 et 7), ce qui empêche cette dernière de revenir à sa position de verrouillage de la figure 4a. La pièce de verrouillage 32 n'est en effet plus sollicitée par l'action de l'utilisateur sur la barre anti-panique 16 et, soumise à l'action de ses moyens élastiques 82, elle tendrait à revenir dans sa position de verrouillage en l'absence du pêne rétractée.The retraction of the bolt 30 during this movement passes it under the locking piece 32 ( Figs. 6 and 7 ), which prevents the latter from returning to its locking position of the figure 4a . The locking piece 32 is indeed no longer solicited by the action of the user on the panic bar 16 and, subjected to the action of its elastic means 82, it tends to return to its locking position by the absence of the retracted bolt.

Le mouvement de rétractation du pêne 30 se poursuivant, ce dernier entre en contact avec l'élément formant butée 56b (bossage) du contre-pêne 34 (figure 3a) et entraîne ainsi le contre-pêne dans un mouvement de rétractation (non représenté sur la figure 7).As the retraction movement of the bolt 30 continues, the latter comes into contact with the abutment member 56b (boss) of the counter-bolt 34 ( figure 3a ) and thus causes the counter-bolt in a retracting movement (not shown on the figure 7 ).

L'appui sur la porte se poursuivant (figures 7 et 8), le pêne 30 franchit l'arête supérieure 36b de la gâche et glisse le long de celle-ci, puis de l'huisserie 18. Le contre-pêne toujours non représenté (en position rétractée) glisse lui aussi le long de la gâche et de l'huisserie. Le pêne 30 en position rétractée empêche toujours le retour de la pièce de verrouillage 32 en position de verrouillage.The pressing on the door continues ( figures 7 and 8 ), the bolt 30 crosses the top edge 36b of the striker and slides along it and the frame 18. The latch still not shown (in the retracted position) also slides along the striker and the doorframe. The bolt 30 in the retracted position still prevents the return of the locking piece 32 in the locking position.

Lorsque la porte est ouverte (figure 9), le pêne 30 et le contre-pêne 34 ont dépassé l'huisserie 18 de la figure 8 (celle-ci se trouve au dessus du pêne et du contre-pêne) et ne sont plus contraints par cette dernière dans leur position rétractée. Ils peuvent alors se déployer sous l'action de leurs moyens élastiques respectifs 60a et 60b et occuper une position déployée (figure 9) qui est une deuxième position déployée pour le pêne et une première position déployée pour le contre-pêne (cette position déployée est limitée par le bord tombé 54a qui vient en butée sur le bord externe de la platine 20b.When the door is open ( figure 9 ), the bolt 30 and counter-bolt 34 have exceeded the frame 18 of the figure 8 (it is above the bolt and counter-bolt) and are no longer constrained by the latter in their retracted position. They can then be deployed under the action of their respective resilient means 60a and 60b and occupy an extended position ( figure 9 ) which is a second extended position for the bolt and a first deployed position for the counter-bolt (this deployed position is limited by the flange 54a which abuts on the outer edge of the plate 20b.

Lorsque le contre-pêne 34 passe de sa position rétractée à sa position déployée, la partie arrière incurvée (recourbée) 56a du bras 56 entre en contact avec le doigt formant élément d'accrochage 86a de la pièce de verrouillage 32. Le doigt 86a est alors maintenu en position haute par le bras 56, ce qui empêche le retour de la pièce 32 à sa position de verrouillage. Ainsi, dans cette position où le pêne est déployé, c'est le contre-pêne qui assure le blocage de la pièce de verrouillage.When the counter-bolt 34 moves from its retracted position to its deployed position, the curved rear portion (bent) 56a of the arm 56 comes into contact with the fastener finger 86a of the locking piece 32. The finger 86a is then held in the upper position by the arm 56, which prevents the return of the piece 32 to its locking position. Thus, in this position where the bolt is deployed, it is the counter-bolt which ensures the locking of the locking piece.

Le pêne 30 ne peut donc pas être bloqué dans sa deuxième position déployée par la pièce de verrouillage 32.The bolt 30 can not be locked in its second position deployed by the locking piece 32.

Sous une action de fermeture de la porte exercée par un utilisateur (flèche montante sur la figure 10), le pêne 30 entre en contact avec l'huisserie 18 (bord inférieur 18a).Under a closing action of the door exerted by a user (rising arrow on the figure 10 ), the bolt 30 comes into contact with the frame 18 (lower edge 18a).

En raison de la géométrie du pêne 30 (face frontale convexe 46), ce dernier s'efface progressivement par contact de sa face frontale bombée 46 avec l'huisserie 18. Les efforts de contact entre la face 46 et l'huisserie sont orientés vers l'axe B1 (axe de la figure 3c). Le décalage des axes A1 et B1 crée un couple de forces qui tend progressivement à provoquer le pivotement du pêne 30 de sa position déployée à sa position rétractée comme indiqué par la flèche sur les figures 10 à 12. Le pêne 30 se rétracte ainsi à partir de sa deuxième position déployée car la pièce de verrouillage 32 est toujours retenue dans sa position de déverrouillage par le contre-pêne 34.Due to the geometry of the bolt 30 (convex front face 46), the latter gradually fades by contact of its curved end face 46 with the frame 18. The contact forces between the face 46 and the frame are oriented towards axis B1 (axis of the figure 3c ). The offset of the axes A1 and B1 creates a pair of forces which gradually tends to cause the bolt 30 to pivot from its extended position to its retracted position as indicated by the arrow on the Figures 10 to 12 . The bolt 30 thus retracts from its second deployed position because the locking piece 32 is always retained in its unlocking position by the counter-bolt 34.

Dans la mesure où le bossage 56b du contre-pêne est décalé angulairement par rapport au pêne 30 (notamment par rapport à sa face arrière ; voir figure 3a), un mouvement de rotation du pêne 30 indépendant de celui du contre-pêne 34 est autorisé par rapport à l'axe A1 sur la plage angulaire qui correspond au décalage angulaire précité.Insofar as the boss 56b of the counter-bolt is offset angularly with respect to the bolt 30 (in particular with respect to its rear face; figure 3a ), a rotation movement of the bolt 30 independent of that of the counter-bolt 34 is allowed relative to the axis A1 on the angular range corresponding to the aforementioned angular offset.

Le positionnement du bossage 56b par rapport à la face arrière du pêne (bord arrière de l'avancée 42) est tel que, lorsque cette face arrière entre en contact avec le bossage, la partie supérieure de la face frontale 46 du pêne est située sous la première partie 76 de la tête de la pièce de verrouillage 32 (figure 11).The positioning of the boss 56b relative to the rear face of the bolt (rear edge of the projection 42) is such that, when this rear face contacts the boss, the upper part of the end face 46 of the bolt is located under the first part 76 of the head of the locking piece 32 ( figure 11 ).

Ainsi, le mouvement de rétractation du pêne 30 entraîne à son tour le mouvement de rétractation du contre-pêne 34 qui se désengage alors du doigt 86a de la pièce de verrouillage 32. Le blocage de cette pièce 32 n'est plus assuré par le contre-pêne 34 mais de nouveau par le pêne 30 qui poursuit sa rétractation en passant sous la tête de la pièce de verrouillage (figure 12).Thus, the retraction movement of the bolt 30 in turn causes the retracting movement of the bolt 34 which then disengages from the finger 86a of the locking piece 32. The locking of this piece 32 is no longer provided by the against -pene 34 but again by the bolt 30 which continues its retraction passing under the head of the locking piece ( figure 12 ).

La pièce de verrouillage 32 est ainsi toujours maintenue en position de déverrouillage.The locking piece 32 is thus always maintained in the unlocking position.

Pendant le mouvement de fermeture de la porte le contre-pêne 34 rétracté glisse le long de l'huisserie 18, puis de la gâche 36.During the closing movement of the door the counter-bolt 34 retracted slides along the frame 18, then the striker 36.

L'action de fermeture se poursuit (figure 13) et le pêne 30 commence à se déployer à partir de sa position rétractée lorsque la face frontale 46 franchit le bord ou arête supérieur 36b de la gâche (figure 14). Le contre-pêne 34 reste en position rétractée et la pièce de verrouillage 32 est maintenue en position de déverrouillage.The closing action continues ( figure 13 ) and the bolt 30 begins to deploy from its retracted position when the end face 46 passes the top edge or edge 36b of the striker ( figure 14 ). The counter-bolt 34 remains in the retracted position and the locking piece 32 is held in the unlocked position.

Lorsque la porte est complètement fermée (figure 15), le pêne retrouve sa première position déployée (pêne ressorti), libérant ainsi la pièce de verrouillage 32 qui reprend sa position de verrouillage/blocage du pêne comme sur les figures 4a-b.When the door is completely closed ( figure 15 ), the bolt returns to its first deployed position (bolt out), thus releasing the locking piece 32 which takes up its locking position / bolt lock as on the Figures 4a-b .

Le contre-pêne 34 reste, quant à lui, en position rétractée (enfoncée) en appui sur l'arête supérieure de la gâche 36.Against the bolt 34 remains, in turn, in the retracted position (pressed) resting on the upper edge of the striker 36.

L'effort d'ouverture de la porte et donc l'effort de déverrouillage/déblocage du système de verrouillage et de déverrouillage 14 est réduit par rapport à un mécanisme à barre anti-panique conventionnel.The opening force of the door and therefore the unlocking / unlocking force of the locking and unlocking system 14 is reduced compared to a conventional anti-panic bar mechanism.

En effet, comme illustré sur les figures 4a-b et 5, il suffit de déverrouiller/débloquer le pêne 30 en actionnant la pièce de verrouillage 32 qui forme un levier pivotant.Indeed, as illustrated on Figures 4a-b and 5 it is sufficient to unlock / unlock the bolt 30 by actuating the locking piece 32 which forms a pivoting lever.

On notera que le système de verrouillage et de déverrouillage 14 comporte un nombre réduit de pièces (trois pièces que sont le pêne 30, le contre-pêne 34 et la pièce de verrouillage 32), ce qui se traduit par un coût économique relativement réduit par rapport à des systèmes conventionnels.Note that the locking and unlocking system 14 comprises a reduced number of parts (three parts that are the bolt 30, the counter-bolt 34 and the locking piece 32), which results in a relatively low economic cost by compared to conventional systems.

La figure 15 illustre un autre avantage du système 14 selon l'invention.The figure 15 illustrates another advantage of the system 14 according to the invention.

Le système 14 coopère par l'intermédiaire du pêne 30 avec une surface d'appui (face 36a) de la gâche 36 qui est parallèle à la surface de la grande face 12a de la porte. Cet agencement permet au système 14 de fonctionner de la même manière (notamment le contre-pêne agit de la même manière en coopération avec la gâche et avec le pêne et la pièce de verrouillage) sur une grande plage de réglage de jeu J entre le dormant 18 et la porte 12. En l'absence de l'invention, il est nécessaire de régler la position de la gâche pour que le contre-pêne et la gâche soient correctement positionnés. Grâce à l'invention le contre-pêne est actif sur une plus grande plage de jeu qu'auparavant. La gâche n'a plus besoin d'être réglée, il suffit pour cela que la gâche soit d'une hauteur suffisante.The system 14 cooperates via the bolt 30 with a bearing surface (face 36a) of the keeper 36 which is parallel to the surface of the large face 12a of the door. This arrangement allows the system 14 to operate in the same way (in particular the counter-bolt acts in the same way in cooperation with the striker and with the bolt and the locking piece) over a wide range of clearance J between the frame 18 and the door 12. In the absence of the invention, it is necessary to adjust the position of the striker so that the counter-bolt and strike are correctly positioned. Thanks to the invention the counter-bolt is active on a wider range of play than before. The striker does not need to be adjusted, it suffices for the striker to be of sufficient height.

Selon une variante non représentée, la surface d'appui 36a peut ne pas être parallèle et/ou pas plane.According to a variant not shown, the bearing surface 36a may not be parallel and / or not flat.

Les figures 17 à 19 illustrent un autre mode de réalisation selon l'invention dans lequel le système décrit en référence aux figures précédentes est appliqué pour le verrouillage et le déverrouillage d'un ouvrant dans une version multi-points.The Figures 17 to 19 illustrate another embodiment according to the invention in which the system described with reference to the preceding figures is applied for the locking and unlocking of an opening in a multi-point version.

La figure 17 représente la porte 12 de la figure 1 affectée des mêmes références et portant le système 14 décrit ci-dessus.The figure 17 represents the door 12 of the figure 1 assigned the same references and carrying the system 14 described above.

Ce système 14 fait partie d'un ensemble de verrouillage et de déverrouillage 100 qui comprend également en position haute et en position basse respectivement deux systèmes de verrouillage et le déverrouillage similaires au système 14 et qui sont reliés audit système 14 par un mécanisme de tringlerie rotatif.This system 14 is part of a locking and unlocking assembly 100 which also comprises in the up position and in the down position respectively two locking and unlocking systems similar to the system 14 and which are connected to said system 14 by a rotary linkage mechanism. .

Le mécanisme de tringlerie rotatif comprend un premier et un second élément de tringlerie rotatifs 102, 104 qui sont tous deux connectés respectivement aux organes 92 (supports boule) équipant les deux extrémités opposées de l'élément de tringlerie A3/79 su système 14 des figures 3a-b et 3d. L'élément de tringlerie rotatif 102 (resp. 104) est connecté en partie supérieure (resp. inférieure) à un système de verrouillage et de déverrouillage 106 102 (resp. 108) formant le point de fixation bas.The rotary linkage mechanism comprises a first and a second rotary linkage element 102, 104 which are each connected respectively to the members 92 (ball supports) fitted to the two opposite ends of the linkage element A3 / 79 of the system 14 of FIGS. Figures 3a-b and 3d . The rotary linkage member 102 (respectively 104) is connected at the top (or bottom) to a locking and unlocking system 106 102 (or 108) forming the bottom attachment point.

Sur la figure 18 le capot de protection du système 108 a été conservé alors que celui du système 106 a été retiré pour faire apparaître la pièce de verrouillage 132 modifiée par rapport à la pièce 32. Le contre-pêne 134 a lui aussi été modifié.On the figure 18 the protective cover of the system 108 has been kept while that of the system 106 has been removed to reveal the locking piece 132 modified with respect to the piece 32. The counter-bolt 134 has also been modified.

Comme représenté à titre d'exemple sur la figure 19, la pièce de verrouillage 132 comporte une tête 172 dont l'extrémité avant destinée à entrer en contact avec le pêne 30 reste inchangée. Toutefois, l'extrémité arrière ne comprend plus de partie d'appui 78. La pièce comprend un corps 170 qui s'étend sensiblement perpendiculairement à la tête et qui, à sa base, comporte deux jambes 170a, 170b qui sont relevées vers le haut de manière à former une fourche. Un tube 180 est équipée à une extrémité d'une tête 180a qui est positionnée entre les jambes 170a-b et qui est configurée de manière à provoquer le pivotement de la pièce de verrouillage 132 autour de son axe de pivotement A2 lorsque ledit tube est lui-même entrainé en rotation autour de son axe. Le tube est équipé à son extrémité opposée d'un organe 180b identique à l'organe 92, à savoir par exemple un support boule. Cet organe 180b est raccordé à son tour à l'élément de tringlerie 102 qui est dans son alignement.As shown by way of example on the figure 19 , the locking piece 132 comprises a head 172 whose front end intended to come into contact with the bolt 30 remains unchanged. However, the rear end no longer includes a bearing portion 78. The part comprises a body 170 which extends substantially perpendicular to the head and which, at its base, has two legs 170a, 170b which are raised upwards. to form a fork. A tube 180 is equipped at one end with a head 180a which is positioned between the legs 170a-b and which is configured to cause the locking piece 132 to pivot about its pivot axis A2 when said tube is - even rotated around its axis. The tube is equipped at its opposite end with a member 180b identical to the member 92, namely for example a ball support. This member 180b is connected in turn to the linkage element 102 which is in alignment.

Le contre-pêne dans cet exemple porte un bras central 156 dont l'extrémité libre vient sous la pièce de verrouillage afin d'empêcher que celle-ci ne puisse entraver le retour du pêne à sa première position déployée une fois qu'il aura été déployée dans sa deuxième position. Le système 108 a la même structure que celle qui vient d'être décrite et est raccordé de façon identique à l'élément de tringlerie 104.The counter-bolt in this example carries a central arm 156 whose free end comes under the locking piece to prevent it from impeding the return of the bolt to its first deployed position once it has been deployed in his second position. The system 108 has the same structure as that just described and is connected identically to the linkage element 104.

Dans la position illustrée sur la figure 17 la porte 12 est fermée et les systèmes 14, 106 et 108 sont verrrouillés.In the position illustrated on the figure 17 the door 12 is closed and the systems 14, 106 and 108 are locked.

Pour déverrouiller la porte, on procède comme pour le mode de réalisation des figures 1 à 16 en appuyant sur la barre anti-panique 16 (ou à partir de l'autre côté de la porte avec une clé spécifique).To unlock the door, proceed as for the embodiment of the Figures 1 to 16 pressing the panic bar 16 (or from the other side of the door with a specific key).

Lors du mouvement de pivotement de la pièce de verrouillage 32 des figures 3a-b et 3d, l'élargissement 88a reste maintenu entre les deux branches de la fourche 90, ce qui entraîne celle-ci, et donc l'axe A3/ barre 79, en pivotement. Ce mouvement de pivotement de l'élément de tringlerie A3/79 permet d'entrainer à son tour en rotation les deux autres éléments de tringlerie 102, 104 auxquels chaque organe 92 est respectivement connecté.During the pivoting movement of the locking piece 32 of the Figures 3a-b and 3d the widening 88a remains held between the two branches of the fork 90, which causes the latter, and therefore the axis A3 / bar 79, to pivot. This pivoting movement of the linkage element A3 / 79 allows in turn to drive in rotation the other two linkage elements 102, 104 to which each member 92 is respectively connected.

La rotation simultanée des éléments de tringlerie 102, 104 provoque à son tour la rotation des tubes 180 (fig. 19) des deux systèmes 106 et 108 et donc le pivotement de la pièce de verrouillage 132, ce qui libère les pênes respectifs 30 desdits systèmes.The simultaneous rotation of the linkage elements 102, 104 in turn causes the rotation of the tubes 180 ( Fig. 19 ) of the two systems 106 and 108 and thus the pivoting of the locking member 132, which frees the respective bolts 30 of said systems.

Ainsi, l'ensemble 100 qui vient d'être décrit comprend un système de tringlerie rotative qui travaille en rotation au lieu de travailler en translation.Thus, the assembly 100 which has just been described comprises a rotary linkage system which works in rotation instead of working in translation.

De manière conventionnelle les tringles des mécanismes anti-paniques multi-points doivent être réglées en longueur lors de leur pose sur la porte. Généralement, les tringles hautes doivent toujours être recoupées au moment de la pose. Ainsi, un réglage systématique de la tringle haute et/ou de la pièce qui la reçoit est à prévoir.Conventionally, the rods of the anti-panic multi-point mechanisms must be adjusted in length when they are placed on the door. Generally, the high rods must always be cut at the time of installation. Thus, a systematic adjustment of the upper rod and / or the part that receives it is expected.

Grâce au mécanisme à tringles rotatives décrit ci-dessus, la longueur des tringles (dans une certaine plage de longueurs) peut ne pas être parfaitement adaptée aux dimensions de la porte sans que cela ne gêne le fonctionnement. On supprime ainsi une opération de réglage fastidieuse au moment de la pose.Thanks to the rotary rod mechanism described above, the length of the rods (in a certain range of lengths) may not be perfectly adapted to the dimensions of the door without this hindering the operation. This eliminates a tedious adjustment operation at the time of installation.
