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 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).
  • 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 .
  • the second portion 78 of the head of the locking piece 32 crosses the wall 20a of the axis support and extends under the bar 16 ( figure 2 ).
  • 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 .
  • 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.
  • 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 .
  • 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.
  • 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.
  • the figure 15 illustrates another advantage of the system 14 according to the invention.
  • 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.
  • 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.
  • the bearing surface 36a may not be parallel and / or not flat.
  • FIGS. 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.
  • the figure 17 represents the door 12 of the figure 1 assigned the same references and carrying the system 14 described above.
  • 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. .
  • 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.
  • 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.
  • 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.
  • the assembly 100 which has just been described comprises a rotary linkage system which works in rotation instead of working in translation.
  • the rods of the anti-panic multi-point mechanisms must be adjusted in length when they are placed on the door.
