Description

the left and right protective parts.

  The present invention relates to a closing coordinator for a door with two overlapping leaves comprising a semi-fixed van tail which is only opened occasionally and a service leaf provided with the covering; the coordinator comprising a housing housing a "control panel associated with the semi-fixed leaf and a retaining latch (4) against which the mobile leaf rests when it

closing movement.

  PRIOR ART We already know of such a closing coordinator, the mechanism of which occupies a significant part of the length of the housing and offers no free space at the middle of the door. In addition, the parts of the mechanism (drive parts, support stop, voting stopper) are complicated, difficult to manufacture and relatively bulky. Guided parts such as the drive part and the support stop are badly guided in the housing and may tend to seize under the effect of significant force and cause

  truction of hinges or leaf.

  Problem posed The present invention aims to remedy these drawbacks and proposes to develop a door closing coordinator whose mechanism is simple, compact and of operation without risk of seizing up, even when the mechanism is subjected to accident.

  so much has brutal operating conditions.

  To this end, the invention relates to a coordinator of the type of find above characterized in that it comprises - a driving part connected to the "control rod, and carry a holding stop, movable relative to the latter, which comes into active position in the path of the "holding ache when not retracted by the" control ache in the neutralized position, - this stop guided in the housing relative to the drive part being maintained in the active position by a compression spring placed between the stopper and the entry piece, this stopper being able to be pushed back from its active position by the "retaining hook when the latter is subjected to a torque exerted by the service leaf, exceeding a threshold , so as to let pass the "holding ache in front of the stopper although the" control ache and the parts to which it is connected are in the active position, - a pivoting stopper controlled by the control rod of the "control ache for block the movement of the drive piece in the direction of neutralization, when the "control arch is not neutralized, s the drive piece and the retaining stop comprise - means for guiding in translation and - a surface in dovetail cooperating when the retaining stop is in the active position relative to the drive part, the surfaces being inclined so as to reach the contact position, the retaining stop

  o be pulled against the workpiece by wedge effect.

  The coordinator according to the invention has the advantage of grouping together the different elements of the mechanism in a reduced space on the side of the "holding hook and leaving a large part of the housing free between the mechanism and the" controlling hook. This free, important part can be used to advantage for the passage of equipment elements and in particular the cremone cited by the firefighter. This cremone bolt is installed in some cases on the semi-fixed leaf near the edge of it (middle of the door) and must in fact allow the semi-fixed leaf to be fixed in the iron position

  meture in certain applications or conditions of use.

  The precise guidance of the retaining stop relative to the drive part prevents any jamming of the retaining stop between the drive part and the housing under exceptional thrust conditions when the mechanism is still in the active position and that the service leaf is closed. Generally, thanks to: 5 different guide means, the parts of the mechanism slide very

  well in relation to each other and in relation to the case.

  According to another interesting characteristic, the means for guiding the wind holding stop constituted by a central rib guided in a groove made in the drive part and constituted

o killing its guiding means.

  This assembly avoids that, in the long run, the spring pushing the retaining stop does not tend to spread the stop or to raise it relative to the retaining piece. On the contrary, this dovetail shape applies the retaining stop by its guide surface against the surface.

  s5 for guiding the drive piece by playing on a corner effect.

  In a particularly interesting way, the pivoting stopper comprises a support branch which can be braced against the drive part and a branch substantially perpendicular thereto and carry a relic axis on the one hand to the control rod And on the other hand

to the remote link.

  And in particular, the support branch of the pivoting buffer, the offset link and the wind extension spring located next to each other

s in the case.

  In order to promote compactness and the reduction in the number of parts, the pivoting stopper has thickness reductions for the parts of these branches capable of overlapping the offset link and the end of the branch bear the articulation to which the control rod and reduced in thickness completely

  the thickness of the control rod.

  The movement of the pieces is favored in that at least some moving pieces have guide bosses for mistletoe

  der and rest against the inside faces of the case.

  is Finally, the drive part has an axis which is connected to the end of the offset link and this axis is located substantially in the middle of the height of the drive part, that is to say sensitive

halfway across the case.

Description of embodiments

  According to FIG. 1, the invention relates to a closing coordinator for a door with two overlapping leaves, namely a semi-fixed leaf 100 which is only opened occasionally and a service leaf 101 provided with the covering 102. The closing coordinator 103 has the function of authorizing the closing of the service leaf 101 only if, beforehand, the semi-fixed leaf 100 has been closed. In fact, the semi-fixed leaf in the closed position pushes back the "control sash 104 from the coordinator 103 and this" sash transmits its movement to a mechanism not shown in FIG. 1 which allows the pivoting of the

  "retaining hook 105 pushed by the service leaf 101.

  This general principle of the coordinator is known.

  According to FIG. 2, the invention relates to a coordinator for io me of a flat 1 bottler, of rectangular section housing and guiding the mechanism of the coordinator. This box 1 is intended to be fixed, in a known way, behind a door with two leaves as has been indicated in FIG. 1. The length of the box is such that the "control panel and the

  "holding ache are located near the hinges of the associated leaf.

  s "control port 2 is pivotally mounted about an axis 3 secured to the housing and the end of" control port 2 is naturally installed to protrude from housing 1 as shown. This position as well as that of the parts ordered by the

  "command display 2 will be called. <active position>.

  On the contrary, when the "control catch 2 is pressed into the housing 1 by the service leaf in the closed position, the control strike 2 and the parts which it actuates will be cited in. <Position

neutralized>.

  The "holding hook 4 is pivotally mounted near the other

  end of the housing 1 around an axis 5 secured to the housing.

  To facilitate the description of the coordinator, an arrow A

  shows the active direction and, an opposite arrow B., the direction of neu

coordination of the coordinator.

  The coordinator has a mechanism housed in the bo-

  so tier and which prohibits the "holding ache 4 from closing (at least up to a certain limit torque exerted on the" holding ache) when the "ache

  2 is in the active position.

  The coordination mechanism consists of a drive piece 6 slidably mounted in the housing 1. This piece 6 com s carries an oblong hole 7 receiving a guide pin 8 integral with the housing, so as to limit the translation of the piece of entranement 6 along the oblong hole 7. This part of entrainment 6 has, in its part 9, turned towards the "control rod 2, a section correspond appreciably to the section of the housing 1 with, as this will be seen below, bearing and guiding surfaces against the walls of the housing 1. In its part facing the "holding arch 4, the drive piece 6 is pledged to receive a holding stop 1O. This retaining stop 10 s is a cam provided, at its front end, with a ramp 11. The retaining stop 10 is slidably mounted relative to the entry piece 6 by being pushed into the left end position represented in FIG. 2 with respect to the drive part 6 by a set of springs Belleville 12 mounted on a spindle 13, one end of which is provided in the rear part 9 of the drive part 6 and the other end is housed with sliding in a bore 14 of the retaining stop 10. The stack of Belleville springs 12 tends to move the retaining stop 10 relative to the drive piece 6 in the longitudinal direction of the housing 1, c that is to say in the active direction A. The end position S of the travel of the retaining stop 10 relative to the drive part 6 is ensured by the contact of two dovetail surfaces 15, 16 belonging one (16) to the retaining stop 10 and the other (15) to the

training room 6.

  As will be seen in FIGS. 5A, 5B, 6A, 6B, the retaining stop 10 comprises a guide piece 17 housed in a groove 18 of the drive piece 6 so as to guide the movement of movement of the stop of holding 10 relative to the drive piece 6 when the stop 10 is pushed and compresses the spring 17, while the drive piece is blocked and cannot move in the direction 2s B. The mechanism also includes a stopper pivoting 17 mounts around an axis 18 integral with the housing 1. This pivoting stopper 17 is an elbow lever provided with a branch 19 turned towards the drive part 6 and a branch 20 connected by an articulation 21 to a connecting rod control 22 also connected to the "control screen 2 at the level of

  ['joint 23 carried by it.

  This pivoting stopper 17 is supported, by its front end 24,

  against the rear face 25 of the drive piece 6.

  The articulation point 21 of the pivoting stopper 17 is connected to the 3s driving part 6 by a remote link 26 connected to a pivot 27 carried by the mounting part 6. This pivot 27 is located substantially

  in the longitudinal median plane of the boftier 1.

  An extension spring 28 is installed between a lug 29 carried by the drive part 6 and a fixed point 30 secured to the bo; tier 1. This extension spring 28 has the function of pushing the driving part 6 as well as the parts kinematically attached thereto in the active direction A. The end position is. again, challenge

  negated by the oblong housing 7 bearing against the stop 8.

  This pushing movement of the extension spring 28 in the active direction (A) is also transmitted by the control rod 22 to the "control rod 2 and tends to make it come out of the housing 1 in

  o the position represented in figure 2.

  Finally, the "holding ache 4 is provided with a return spring 31 hooks on the one hand to a lug 32 of the" ache and, on the other hand, at a 5x point 33 of the boftier 1 in an attempt to tilt the "holding ache

  4 in the out-of-housing position like the one shown.

  Figure 2 shows the closing coordinator in the active position: the control strike 2 is extended, which means that the leaf

  semi-fixed (not shown in this figure) is not firm.

  In this position of the "control arch 2, the drive piece 6 and its holding stop 10 occupy the active position o (extreme position to the left according to FIG. 2). In this active position, the holding stop 10 comes with its ramp 11 in the tilting path of the "holding ache 4 and blocks the rotational movement which the" holding ache 4 might want to execute, pushed by the

service leaf not shown.

  If, however, in this position, the "holding ache 4 is subjected to a sufficient torque, the" holding ache 4 pushes the holding stop 10 by compressing the Belleville springs 12 until it can pass in front of the holding stop. This provision is a safety measure to prevent an accidental force exerted on the service leaf from destroying the pommels of the service leaf which would rest on the

  "maintenance ache and would benefit from considerable leverage.

  When the "control arch 2 is put in the neutralized position, that is to say when it is pressed into the housing 1 by the semi-fixed leaf, this pivoting movement of the" arch controls the movement of the connecting rod 22 in direction B which pulls on the pivoting stopper 17 to make it tilt and no longer brace against the drive piece 11. This pivoting movement of the stopper 17 also starts the link 26 which pulls the piece drive 6 with its retaining stop 10 always in the neutralization direction B. The movement is such that the retaining stop 10 emerges with its ramp 11 from the path of the "retaining hook 4 which can thus be retracted normally

in the case in the case 1.

  As it appears in FIG. 2, the mechanism controlled by the "control ache 2 is moved near the" holding ache 4 and the control rod 22 will be dimensioned as a function of the length of the

  coordinator, necessary depending on the width of the door with two leaves.

  But in addition, the different elements of the mechanism are grouped together so as to occupy the least possible space in the housing. The part of the housing adapted to the width of the door adapted to the length is shown to be cut (reference C). Thanks to a grouping of the elements, there is thus free space towards the middle of the coordinator, that is to say near the edge of the service leaf, which in particular allows the passage of an IS cremone bolt in the free part corresponding in the rectangle figure

with a broken line 34.

  The different elements of the coordinator will be described below

  after in more detail with the aid of Figures 3 to 8.

  FIG. 3 shows the "control screen 2 formed by two arms 40, 41 one of which ends in a cam 42 against which the semi-fe leaf rests. The smooth bearing 43 is of thickness greater than that arms 40, 41 to form the surfaces in a circle crown resting on the inner faces of the housing 1. It is also to be noted that the arm 41 is split and receives in the meantime the control rod 22 arti

culee around axis 23.

  FIGS. 4A, 4B show the "retaining hook 4 formed by an elongated rectangular body, having at one end a smooth bearing 50 extending on both sides of the" hook 4 by an extra thickness of fa

  con that the total thickness corresponds substantially to the thickness of the bo-

  so tier 1 by having bearing surfaces in a circle to slide

in the case.

  The other end of the body of "ache 4 ends with a spout 51 which makes it possible to lean on the ramp 11 of the stop and, if necessary, to push it back. The area of" ache 4 against which the s5 service leaf corresponds to the top of the body of "ache and bears the reference 52, the fulcrum moving as the leaf closes. Finally the" holding ache has on both sides a wise bos 53. The "ache is guided by these bosses between the walls of the

case 1.

  FIGS. 5A, 5B show a fitting piece 6 revealing the groove 60 for the guide piece of the stopper 10, the dovetail surface 15 and the recess 61 around and beyond the axis 27 which receives the end of the rod 26. The drive piece 6 also has on its two faces the bosses 62 and 63 for guiding

  lean against the faces of the case.

  Finally, these figures show the bearing surface 64 bordering the groove 60 and against which rests and can slide the hand stop.

yours 10.

  Figures 6A, 6B show the detail of your hand stop 10 leaving above all appear in addition to the characteristics already described, the bearing surface and the guide 70 as well as the guide piece 71 s cooperating respectively with the guide surface 64 and with the groove

of the workpiece 6.

  Figure 7 shows the very particular shape of the pivoting stopper 17. In addition to the housing 80 forming the bearing of the pivot 18, the branch 19 cites support branch, has a boss 81 by which the o stopper can come against the short side correspond of the housing 1. The support branch 19 is reduced in thickness 82 in one face to pass by pivoting under the link 26 when the stopper 17 is pivoted in the neutralization position. This thickness reduction is carried out by the part 82 of the other branch 20. These thickness reductions 82, 83 correspond: 5 substantially to the thickness of the offset rod 26. The end of the branch 20 ends with a complementary thickness reduction 84, around the bearing 85 receiving the axis 21 to allow the superimposition on this articulation point, both of the link rod 26 and of the link of com

request 22.

  FIG. 8 shows the remote link 26, that is to say of the shape with two branches 90, 91 one of which (90) allows the offset between the point of articulation on the axis 21 and the other, [ 'articulation on the axis 27 of the mounting piece 6 and which is located substantially at the middle of the width of the piece 6. The branch 90 has an oblong hole 92 for receiving the axis 27 3s with the play necessary for movement. The other branch 91 has an orifice 93 forming a bearing for the axis 21. This offset link 26 makes it possible to pass alongside the extension spring 28 and thus shorten

the size of the mechanism.

  The pivoting stopper 17 being connected to the drive piece 6 by a remote link 26 transmitting the movement of the commando link and bypassing the extension spring 28. The latter pushes the

  drive piece 6 in active position.
