  In the description which follows, as well as in the

  claims, the terms above will be used without limitation,

  low, vertically, horizontally, upper, lower, etc. with reference to the figures. In these same figures, identical, similar or analogous components and elements

  will be designated by the same reference numbers.

  FIGS. 1 and 2 show an emergency closing assembly 20 intended to equip a door 22 which is pivotally mounted, here around a vertical axis, with respect to fixed elements including a frame including the upper part 24 and the lower part 26 are partially illustrated and

schematically in the figures.

  According to a known general design, the assembly 20 comprises a cremone bolt 28 allowing the operation of two vertical rods high 30 and low 32 respectively, each of which makes it possible to act on a high 34 and low 36 sub-assembly each of which comprises in particular a bolt 38 , 40 and a strike

42, 44 respectively.

  In the example illustrated in the figures, and this without limitation, it is the top sub-assembly 34 which includes

  automatic tail means while the sub-

  bottom set 36 is simpler in design while using a large number of components common to both

types of bolt.

  Without departing from the scope of the invention, the low sub-assembly 36 could be equipped by itself with automatic tailplane means, the two subassembly can of course also be each of the automatic tailplane type. The design of the cremone bolt 28 will now be described in detail, more particularly with reference to FIGS. 3 to 6.

B354DOC 2781003

  which is arranged an operating mechanism the design of which is that it can cause the longitudinal and simultaneous translation of the rods 30 and 32, in the

both directions.

  For this purpose, the operating box 44 comprises a fixed support of 46 which is a piece of cut and folded sheet metal comprising a bottom plate 47 intended to be fixed on the inner face 49 of the door and two vertical and opposite lateral wings 48 between which are received

  lo main components of the operating mechanism.

  In the vicinity of the upper end of the fixed support 46, the two wings 50 have a fixed axis 52 horizontal and parallel to the plane of the inner face 49 of the door 22, around which the upper end 54 of a plate is pivotally mounted. push 56 allowing the user to control

the operating mechanism.

  The push plate 56 is of generally rectangular shape with its length oriented in the vertical direction and the lower end 58 of which extends, in the direction of the bottom plate 47 of the fixed support 46, by a

  perpendicular and therefore substantially horizontal plate 60.

  The maneuvering box comprises a cover 61 of generally rectangular parallelepipedic form, which is open in its rear face to surround, protect and dress the operating mechanism and whose external vertical face 66 has an opening 62 of complementary rectangular general outline that of the thrust plate 56 which, in the example illustrated in the figures, is practically completely visible through the opening 62, only its upper part 54 being hidden

  by the upper part 64 of the external face 66 of the cover 61.

B354DOC 2781003

  Thus, the thrust plate 56 can protrude outside of the maneuvering box 44 through the opening 62 to come to occupy its extreme angular position of closure illustrated in FIGS. 1, 3 and 4, or else it can be pressed horizontally inside the operating box 44 to occupy its extreme angular opening position illustrated in FIGS. 2, 5 and 6 in which the plate 56 extends substantially vertically in the general plane of the

external face of the cover 61.

  In order to improve the external appearance of the cremone bolt when the push plate 56 is in the closed position and to increase the security of the assembly 20 by preventing the user from trapping his fingers under the push plate 56, the latter also comprises two i5 parallel and opposite vertical lateral cheeks 68 which give the push plate 56, in association with the lower horizontal plate 60, a shell shape which can

  be made for example by molding.

  On its internal face 70, the thrust plate 56 comprises a piece 72 in the shape of a stirrup, added for example by welding, two parallel and opposite vertical wings 74 each having a buttonhole 76 of generally longitudinal orientation which is delimited vertically towards the top by a rounded bottom 78 and which is

open vertically down.

  The open ends of the buttonholes 76 make it possible to mount an axis 80 which is produced in the form of a horizontal cylindrical rod, of geometric axis A2 parallel to the fixed geometric axis A1 of pivoting of the thrust plate 56. L axis 80 is carried by the lower end 81 of a double lever 82 whose upper end 83 is mounted at

B354.DOC 2781003

  It rotates on the wings 48 of the fixed support around a fixed axis 85 of geometric axis A3 parallel to the geometric axes A1 and A2. Thus, the axis 80 carried by the thrust plate 56 always moves in a circle centered around the axis A3 and

  remains inside the buttonholes 76.

  The axis 80 also constitutes the articulation axis, relative to the thrust plate 56, of the upper end 86 of a double connecting rod 88, the lower end 90 of which carries a movable control rod 92 which is a rod cylindrical axis

  geometric A4 parallel to the axis of articulation 80.

  As can be seen in FIGS. 3 and 5, the opposite free ends 94 of the control rod 92 are received and guided in longitudinal sliding each in a longitudinal guide light 96 formed in a corresponding wing of the fixed support. Each guide light 96 is delimited by an upper end 98 and by a lower end 100. Thus, the deflection faculties of the movable control rod 92 in the guide lights

96 perfectly defined.

  The central section 102 of the rod 92 is, for its part, slidably received in two control slots 104 which are parallel slots of longitudinal orientation, each of which is formed in a vertical lateral wing 105 belonging to a first slide 106 of the operating mechanism. which is a piece of cut and folded sheet metal which has a bottom plate 108 which connects the wings together and which are guided in sliding between the internal faces opposite the lateral wings 48 of the fixed support 46 so as to ensure a longitudinal sliding guide of the first slide 106, also called high slide 106,

in both opposite directions.

B354.DOC

B354DOC 2781003

  The guide lights 96 and the control lights 104 are formed, respectively in the fixed support 46 and in the slide 106, in the vicinity of the lower vertical ends 110 and 112 of these two elements 46 and

106.

  The first slide 106 extends substantially over the entire height of the fixed support 46 and of the operating box 44 inside which it can slide longitudinally between its upper upper closed position in which the upper upper edge 114 of its bottom plate 108 is located near the upper transverse face 116 of the cover 61, and its lower lower opening position in which the lower edge 112 of the wings 105 is located near the

  lower transverse face 118 of cover 61.

  The operating mechanism includes a spring

reminder 120.

  In the embodiment of the invention illustrated in FIGS. 3 to 6, the return spring 120 is a helical tension spring whose upper end 122 is hooked on the fixed axis 85, and whose other lower end 124 is hooked on the movable control rod 92 so as to permanently urge the latter vertically towards the

  high, that is to say in the direction of the fixed axis 85.

  Thus, the return spring 120 permanently biases the lever 82 and the control rod 88 in their angular positions illustrated in FIG. 3 in which the thrust plate 86 is in its closed position. This angular position of closure of the thrust plate 56 is determined precisely by the coming into abutment of a tab 130 formed at the free end of the plate 60 and which cooperates with a portion facing 132 of the wings 48 of

fixed support 46.

B354.DOC 2781003

  From this closed position of the thrust plate 56, if one acts on the latter to rotate it clockwise in the direction of its angular closed position, one causes the longitudinal extension of the return spring 120 and the sliding of the control rod 92, vertically downwards, inside the guide lights, the central section of the control rod 92 cooperating with the lower longitudinal ends of the control lights to cause the longitudinal sliding, vertically down the slide 106 relative to the fixed support and this until the free ends of the control rod abut against the lower longitudinal ends of the guide lights

  to reach the unlocking position of the door.

  To this end, the upper free end 114 of the bottom plate 108 of the slide 106 is connected in longitudinal translation to the proximal lower end 136 of the upper rod by a pin 137. Thus, the operating mechanism allows direct control longitudinal displacements in both directions of the upper rod. The operating mechanism, still acting on the push plate 56, also makes it possible to control the longitudinal movements in both directions of the bottom rod 32 by means of a second slider 138, also called bottom slider, which is mounted and guided in sliding

  between the lateral wings 105 slide 106.

  The bottom slider 138 also comprises two parallel lateral wings 139 which are received between the wings 105 of the slider 106 and each of which comprises, in the vicinity of its upper end 140, a light 141 for guiding the

B354.DOC 2781003

  bottom slide 138 in which the central section is received

  a fixed guide rod 143 carried by the fixed support 46.

  In order to ensure the sliding of the bottom slide 138 indirectly by the top slide 106, there is provided a movement return device 142 which

  intervenes between these two slides 106 and 138.

  The device 142 is here constituted by a double deflection lever 144 mounted for rotation around the fixed guide rod 143 and each of the free ends opposite to 146 and 148 comprises a drive pin 150, 152 which is received in a corresponding hole 151, 153 of slide 106

  and slide 138 respectively.

  The invention is of course not limited to this single design of the movement return device, this i5 can for example be of the crankpin or pinion and rack type. For driving the bottom rod, the proximal end 154 of the latter and fixed to the lower end

  156 of the bottom slide 138 by a pin 159.

  The upper sub-assembly 34 will now be described in detail. The latch 34 comprises a lower part which houses the bolt 38 and an upper part which constitutes the fixed strike 42. The lower part is a block 158 comprising a plate 160 forming a fixed support which comprises a bottom plate 162 and two vertical and opposite lateral wings 164. The bottom plate 162 and designed to be fixed by screws on the

inner face 49 of door 22.

  In the vicinity of their upper ends 166, the

  lateral wings 164 of the plate 160 carry a fixed axis 168 -

  with horizontal geometric axis A5 parallel to the articulation axis

B354.DOC 2781003

  A1 of the thrust plate 56 - articulation of the bolt 38 and which extends transversely between the two lateral wings 164 between which the body 170 of the bolt 38 is pivotally received, the transverse width of the body 170 of the bolt 38, delimited by its two opposite lateral faces 172, being slightly less than the distance separating the internal faces

facing the two wings 164.

  The body 170 of the bolt 38 carries, in a fixed manner, a cylindrical drive rod 176 whose geometric axis A6 io is parallel to the axis of rotation A5 of the bolt 38 and which is arranged in the vicinity of the axis 168 substantially To the same

altitude than the latter.

  Under the action of the drive rod 176, the bolt 38 is capable of pivoting in both directions around its 1is pivot axis A5 to cooperate with the keeper 42 or to

  be retracted outside the strike.

  The upper part of the body 170 of the bolt 38 is delimited by a flat outer transverse face 180 and by an inner transverse face 182 of profile in the shape of a convex cylinder arc and, in the closed position illustrated in particular in FIG. 8, it is received in a housing of complementary shape 184 of the keeper 42 which is open vertically downwards and which is delimited by two walls

correspondents 186 and 188.

  The keeper 42 is for example a molded part which comprises, adjacent to the cavity 184, a lateral recess 190 which is open horizontally in the external vertical face 192 of the body of the keeper 42 and vertically in the lower horizontal face 194 thereof. . The recess 190 is bounded horizontally inwards at a vertical face of

background 196.

B354DOC 2781003

  The function of the lateral recess 190 will be explained later in association with the trigger arm of the

automatic tail means.

  The drive rod 176 is received by its opposite ends in two parallel drive holes 200 each of which has an L-shaped bent profile and is formed in a vertical lateral wing 202

belonging to a coach 204.

  The two parallel and opposite wings 202 of o10 the coach are connected together by a vertical plate

  206 which is parallel to the bottom plate 162 of the plate 160.

  The plate 206 of the coach 204 is guided in sliding under tabs 207 each belonging to one

  lateral wings 164 of plate 160.

  The drive lights 200 are formed in the vicinity of the upper ends 208 of the two wings 202 of the coach 204, while the lower end 210 of the plate 206 thereof is linked in translation with the end

  distal upper 212 of the upper rod 30, by a screw 214.

  Starting from the position illustrated in FIG. 8, a vertical sliding movement towards the bottom of the rod causes an identical displacement of the driver 204 relative to the plate 160. This displacement of the coach causes a relative displacement of the rod training 176

  relative to the drive light 200.

  Thus, the drive rod begins by traversing the first section 220 of longitudinal orientation, from bottom to top while considering FIGS. 8 and 13, then it comes into contact with the elbow 222 which automatically causes it to enter

  the substantially horizontal section 224.

  Due to the pivoting mounting of the bolt 38 around its fixed axis of rotation 168, the path of the section 224 causes

B354.DOC 2781003

  automatic pivoting of the bolt 38 anti-clockwise

  timetable considering figure 8.

  The bolt 38 then passes from its projecting position illustrated in FIG. 8 to its retracted position illustrated in particular in FIG. 11 in which it can be seen that it is then possible to move the door relative to the frame, that is to say that the

  sub-assembly 34 forming a top lock is unlocked.

  The unlocking stroke of the bolt 38 is accomplished against an elastic restoring force which permanently urges the driver 204 and the bolt 38 to their locking position illustrated in particular in FIG. 8. This elastic restoring force is exerted by a return spring 226 which, in the example illustrated in the figures, is a helical compression spring which is interposed longitudinally between the

  1s plate 160 and the coach 204.

  More specifically, the plate 160 comprises a tab 228 produced from the bottom plate 162 and against which the lower end 230 of the spring 226 bears, the other upper end 231 of which is hooked on a return rod 232 of horizontal orientation and which is received in notches in an arc 236 which are formed in the wings

side of coach 204.

  During the opening stroke of the lock 34, the driver

  204 compresses the return spring 226.

  In accordance with another characteristic of the invention, means are provided for causing the automatic tail, that is to say means which retain the bolt 38 in the retracted opening position as long as the door is open, and this even if the user has released his opening force previously applied to the thrust plate 56 of the operating mechanism. In addition, these means must

B354DOC 2781003

  cause the lock to automatically lock again 34

when the door 22 is closed.

  For this purpose, the lock 34 includes a lever 240 for blocking the driver 204. The lever 240 is a piece of folded and cut sheet metal which extends in a plane parallel to the lateral and vertical wings 164 of the plate 160 and more precisely along the right wing considering FIG. 9. The plate-shaped locking lever 240 is articulated relative to the plate 160 by its lower end 242, around a horizontal fixed axis A7 parallel to the axis of

pivoting the bolt 38.

  In its central part 244, locking lever 240 has a locking tab 246 which is folded transversely at a right angle so as to extend opposite the outer longitudinal edge 248 of the right side wing of the driver 204. This edge 248 comprises, as can be seen in particular in FIGS. 8 and 13, a notch 250 delimited by a longitudinal edge, of vertical orientation 252

  and by a transverse edge 254 of horizontal orientation.

  The locking tab 246 is thus capable of being received in the notch 250 so that its inner face 256 comes to bear against the longitudinal edge 252 and so that its lower edge 258 comes into abutment against the

horizontal edge 254.

  In the closed position illustrated in FIGS. 8 and 9, the locking tab 246 bears by its internal face 256 against the portion facing the longitudinal edge 248 of the wing of the driver 204 and it is permanently resiliently biased in this position by a locking spring 260 which is a helical compression spring interposed between the

  plate 160 and the outer face of the locking tab 246.

B354.DOC 2781003

  Thus, the locking lever 240 is permanently biased in rotation about its articulation axis A6

  clockwise considering figure 8.

  During the opening stroke of the lock 34, the driver 204 moves vertically downward relative to the locking lever 240 and the locking tab 246 then comes opposite the notch 250. Under the action of the spring 260, the locking tab automatically enters

  the notch 250 to occupy the position illustrated in FIG. 11.

  In this position, if the vertical traction force applied to the driver 204 is released, the latter tends to rise under the action of the return spring 226, but this movement is immediately stopped because the lower edge 258 of the locking tab 246 abuts against the edge

horizontal 254 of the notch 250.

  To allow the latch to close again and therefore to release the driver 204, the free upper end of the locking lever 240 is shaped as an arm of

trigger 270.

  This trigger arm 270 extends longitudinally vertically upwards beyond the lower part 158 of the latch 34 to be received, when the door 22 is in the closed position, in the lateral recess 190

strike 42.

  When the door 22 is closed, that is to say when the lower part 158 of the latch 34 moves from left to right, considering FIG. 11, with respect to the striker 42, the outer face 274 of the trigger arm 270 will come into contact with the vertical bottom 196. This results in a rotation of the locking arm 240 counterclockwise which has the effect of causing the locking tab 246 to come out of the notch 250 and therefore of

B3 54.DOC

B354.DOC 2781003

  again allow relative movement of the driver 204, vertically upward, relative to the plate 160

  under the action of return spring 226.

  The combined actions of the return springs 226 and of the blocking 260 therefore make it possible, by virtue of the design of the blocking lever 240, to ensure the tail function

  automatic defined by standardization.

  To improve the external appearance of the lower part of the top lock 34, a covering hood 280 surrounds the assembly

of its components.

  As can be seen by referring to FIG. 16, the upper part 282 of the bottom latch 36 is of generally identical design to that of the lower part 158 of the top latch 34 and it notably uses the same components which allows a large standardization during

the making.

  When a lock is simple, that is to say when it does not include automatic tailing means and as is for example the case of the bottom lock 36 illustrated in the figures, it suffices to remove the lever blocking, all the other components being also identical to those of a complex lock, that is to say a lock comprising the blocking lever.
