Description

- 1 - "Lock and security system equipped with such a lock" La

  The present invention relates to a lock for a door, window or window leaf comprising a housing containing at least one movement mechanism, actuated by a user, of at least one closing means between a first position in which the lock is in a state open and a second position in which the lock is in a closed state. It also relates to a security system for a dwelling comprising at least one

  leaf equipped with a lock of this type.

  It relates more particularly to a built-in lock for example of the cremone bolt type which is intended for the closing of French windows and service doors. It consists of a housing containing a mechanism for actuating two rods provided with locking elements cooperating with strikes made in the fixed frame of the French window. The rods and the casing are concealed by a metal headrest fixed to the door joinery. The cremone bolt can adopt a locked state in which the rods are deployed and the locking elements are engaged in the keepers and an unlocked state in which the rods are

retracted.

  The cremone bolt may further include a means of blocking the movement of the rods when they are deployed allowing it

  to adopt a third state known as condemned.

  The cremone bolt can be fitted with a 1/2 turn bolt which allows

close the door by pushing it.

  The locking mechanism is operated by raising the handle, which then makes it possible to lock the door with a turn

key activating the barrel.

  Unlocking is carried out by pressing the handle, which has

  also for retracting the bolt 1/2 turn.

  In the case of such a lock, it is therefore after having carried out the two operations of lifting the handle and then giving a turn of the key that the user can be assured that the intrusion without break-in

is prohibited.

  However, the user cannot know if the door is locked simply by looking at it. He has only the possibility of checking by pressing the handle. If it is blocked, the lock is locked. If it opens, you have to redo both

operations described above.

  This problem also arises for cylinder locks provided with a deadbolt. There is no other way to check if the door is properly

  doomed to press the handle.

  Another problem also arises concerning the cremone bolts. The function of the multipoint locking system is to limit the deformation of the window frames over time, the lifting of the handle

  allowing to obtain a greater pushing force than with the key.

  However, it has been found that users often do not lock their French windows due to the complexity of the operation. This results in significant risks of malfunction of joinery and burglary without burglary which can hardly be taken into account.

i 5 charged by insurance.

  The object of the present invention is to overcome the drawbacks mentioned above and to propose a means of signaling the state of the lock. It provides a lock for a leaf comprising a housing containing at least one movement mechanism, actuated by a user, of at least one closing means between a first position in which the lock is in an open state and a second position in which the lock is in a closed state, characterized by a device for visual signaling of the state of the lock comprising: - means for establishing in a display means data representative of the state of the lock; and a means of changing said data in said means

  display subject to the movements of said movement mechanism.

  The lock thus provided with an automatic signaling means of the state of the lock which is slaved to the actions of the user. This allows the latter to see at a glance whether the lock is open

  or closed without having to act on the handle.

  The present invention relates to any type of lock, in particular embedded, comprising a deadbolt, or of the type

simple cremone bolt or barrel.

  - 3 - In the case of a cremone bolt, the user will be encouraged to operate it correctly. The security level will therefore be increased and

  limit the deformation of the amount of the leaf.

  According to a first embodiment, the signaling device is mechanical. The display means is a mobile indicator comprising at least one sector having a visual appearance chosen from a color, white, black and a shade between white and black, said sector being visible outside the lock. through a display mask and its visual appearance corresponding to the data representative of the state of the lock. You can choose for example to display through the display mask white, gray or black when the closure means is open and the color red when it is closed or else

  classic green for the open state.

  The mobile indicator is located near the cleanliness plate of the lock, the means for establishing the data representative of the state of the lock comprising means for connecting said mobile indicator to a mobile means controlled by the change means of said data. An opening

  is made in the housing for the passage of the connecting means.

  Advantageously, the indicator is rotary capable of being rotated by a connecting means such as a square section axis connected to a rotary disc controlled by means of change formed on the

  movement mechanism of the closure means.

  The control can be achieved by a lug formed on the closure means cooperating with a groove formed on the rotary pinion, for example in the case of a displacement in translation of the closure means. The control can also be achieved by a toothing formed on the drive mechanism of the closure means

meshing a pinion.

  In the case of a built-in lock, the signaling device can be integrated in the housing of the lock and requires for its installation only the drilling of an additional hole in the material of the leaf, for example the joinery, and in the cleanliness plate on or under which the display means is installed, the square axis connecting

  the housing and the rotary indicator.

  In the particular case of a barrel cremone bolt, which can adopt three states, and comprising two closing means (rods and rod locking bolt), a declutching means is provided to allow the two means of changing the data - 4 - representative of the state of the lock to act independently of one another. This declutching means can be useful in particular for

  display both a locked and locked state of the cremone bolt.

  According to a second embodiment of the invention, the signaling device is electric and comprises at least one diode visible outside the lock supplied by an energy means and a fixed contact area formed in the boot cooperating with a mobile microswitch arranged on the means of displacement of the closure means, the contact between the contact zone and the microswitch

  being produced at the end of travel of said displacement means.

  The diode (s) can be placed on a plate installed below or attached above the cleanliness plate of the lock. The open state of the lock can be indicated by an off LED

  i 5 and the state closed by a lit LED or a slow flashing.

  It is also possible to use a two-color diode reproducing the two colors or two diodes of different color, each diode being connected to a fixed contact area formed in the housing cooperating with a mobile microswitch arranged on the means of displacement of the closure means, the contact between each contact zone and the associated microswitch being produced at the end of the travel of said displacement means. A connector constituted by a rod of square section can advantageously be used to define contact terminals for connecting the contact zones and the diodes, the support plate of the

  diodes being provided at the end of the connector.

  The device can be supplied with energy by a lithium battery housed under the cleanliness plate outside the housing of the

  lock or any other suitable energy source.

  According to yet another embodiment, the signaling device comprises electronic components and in particular a means of transmitting the data representative of the state of the lock, for example to a centralized management panel which can be

  advantageously coupled for example with an alarm.

  The present invention indeed provides a security system for a housing comprising at least one door, French window or window, characterized in that it comprises a lock provided with an electronic signaling device according to the invention and a housing

  receiver of the data representative of the state of the lock.

  In addition, the system may include a means of displaying the representative data transmitted allowing the user to quickly check the entire state of its locks. According to a preferential aspect, the system will be coupled to a

  alarm to increase the security level.

  According to another aspect, the system could be connected to a device for managing the cut-out of heating depending on the data.

  representative of the state of the transmitted lock.

  The present invention will be better understood and others

  characteristics and advantages will appear in the light of the description

In the example chosen and shown in FIGS. 1 to 15, the cremone bolt 1 comprises a barrel 2, a bolt Y2 round 3, two high rods 4 and low 5, a mechanism 6 for moving the rods back and forth and for retracting the Y2 turn bolt and a mechanism 7 for moving a locking bolt 8 for the rods, the assembly being housed at least in part in a housing 9 the bottom 10 of which extends in the plane of FIG. 1 and which is closed using screws cooperating with tapped holes 11 by a cover 1 6 (shown in Figures 10 and 12). The rods 4 and 5 are in two separate parts which can be connected to the assembly: a first part constituted by a rod slide, respectively 4A, 5A, which cooperates with the mechanism 6 for moving the rods and a second part (not shown in the figures) comprising at its end locking elements (not visible in the figures) cooperating with

  strikes made as part of the French window.

  For the purposes of the description, we arbitrarily define the

  top and bottom with reference to the top and bottom of Figure 1 and the front and

  the rear with reference to the left and right of Figure 1.

  This type of cremone bolt is typically intended to equip a French window with one or two leaves, a recess being formed in the part of the frame of the leaf opposite the hinge and comprising a central part for embedding the housing 9 closed by its cover and through grooves on the top and bottom edges of the leaf to accommodate the rods. A headrest 12, consisting of a longitudinal metal plate and fixed with two screws 13 to the housing 9, closes this recess once the housing 9 is installed. It includes an opening 14 for the passage of the latch 1/2 turn 3 and holes 15 for the

  passage of the screws 13 and to accommodate their heads.

  -7- The cremone bolt can adopt three operating states. A first state known as unlocked in which the rods are retracted (Figure 1), a second state known as locked in which they are deployed (Figure 2), the locking elements cooperating with the strikes of the frame of the French window, and a third state (Figure 3) said locked and locked, intervening after a turn of the key, in which the

  movement of the rod slides once deployed is blocked.

  The detailed operation of the cremone bolt will be explained later.

  The mechanism 6 for moving the rod slides and retracting the 1/2 turn latch 3 comprises a rotary actuator commonly called a follower made up according to the present invention of two half-shanks which are driven either simultaneously or

  individually rotated when the handle is operated: half

  follower said master 18 planned to move the bolt 2 turn 3 and a half

  said auxiliary follower 17 which acts on the bottom rod slide 5A, the master half follower 18 being disposed against the bottom of the housing. As best seen in FIGS. 8 and 9, the master half-follower 18 comprises a square opening 20 into which the square shaft of the window door handle engages, a first disc 22 shaped to serve as rotation shaft with master half-follower 17 and a second disc 24, of diameter larger than the diameter of the first disc 22, provided with an actuating finger 25 of a transmission bar 26 serving to retract the bolt Y2 turn (as will be explained below) and a notch 27 for indexing the handle in

  rest position, that is to say substantially horizontal. The half

  auxiliary follower 17 is constituted by a flat annular ring 30

  the central opening 29 of which fits onto the disc 22 of the half

  master follower 18 and has radially projecting two toothed sectors 32, 33 (the teeth of which are not shown), respectively one after the other counterclockwise, the first sector 32 of a larger diameter as the second 33. The first toothed sector 32 is adapted to cooperate with a rack formed on the bottom rod slide 5A so as to move it back and forth. The second toothed sector 33 is adapted to mesh a toothed pinion 188 (not shown in FIGS. 1 to 3) in the context of the device for signaling the state of the lock which will be described below. The second toothed sector 33 has a chamfered front edge 34 which comes into contact with the rear wall 60 of the housing when the cremone bolt is locked as in FIG. 2 by

example.

  The master 18 and auxiliary half-spindles 17 are disengageable thanks to a system of cams cooperating with recesses. More specifically, the ring 30 of the auxiliary half-follower 17 comprises two drive cams 41a and 41b constituted by zones of material in relief (represented by hatching in FIG. 8) which are diametrically opposite one of the 'other and which each represent 1/8 of the ring. One of the cams 41a is situated on the side of the toothed sectors 32 and 33. The disc 24 of the master half-follower 18 comprises two diametrically opposite recessed sectors 42a and 42b in which the cams 41 a and 41b are housed respectively when the half - master and auxiliary threads are assembled. The recessed sectors 42a, 42b represent Y4 of the disc 24 and are therefore

  larger than the drive cams 41a, 41b.

  Conversely, the hollowed-out sectors 44a and 44b formed between the cams 41a and 41b of the auxiliary half-follower 17 cooperate with the raised cams 45a and 45b defined between the hollowed-out sectors 42a and 42b of the master half-follower 18 (shown hatched on the figure 9). Thus, for each cam, a declutching zone is defined in which it is inactive. The cams are located near the axis of rotation of the

  handle which allows balancing of efforts.

  The two half-spindles are therefore driven together in rotation under the action of the handle within the limit of the cam strokes

  drive. Detailed operation will be explained later.

  To allow the two rod slides to move together in opposite directions, two reversing toothed pinions 21, 21 ′ are arranged one above the other between the top rod slides 4A and bottom rod 5A. Their respective axis of rotation extends perpendicularly to the bottom 10 of the housing and their respective toothing meshes on the one hand with the rack 35 of the bottom rod slide 5A and on the other hand with a rack 36 formed at this

  effect on the lower part of the high rod slide 4A.

  -9- A leaf spring 40 is used to index the handle in the rest position, substantially horizontally. It has at one end a boss 41 cooperating with the indexing notch 27 of the master half-follower 18 and at the other end a return at right angles 42 towards the boss 41 for its retention in the housing as it will

explained further.

  The actuation mechanism of the Y2 turn 3 bolt comprises the transmission bar 26, which extends at rest parallel to the rod slides, the rear face 54 of its lower end 55 being biased by a return spring 57 extending perpendicularly , The rear end of the spring 57 being in abutment against the rear edge 60 of the housing, while the front face 62 of the lower end 55 of the bar 26 is located in the field of travel of the finger 25 of the half-follower master 17. The spring 57 is used to permanently return the handle to the rest position. At its upper end 65 the transmission bar 26 has a "U" shape, inverted in FIGS. 1 to 4, with a lumen for the passage of a shaft 67 of circular section which extends perpendicularly on the one hand towards the back of the bolt 2 turn 3 where it is

  fixed and, on the other hand, opposite, behind the transmission bar 26.

  A front return spring 68 is formed around the portion of the shaft 67 located between the bolt 72 turn and the front face of the transmission bar 26. A rear return spring 69 is formed around the portion of the shaft 67 located behind the bar 26 bearing at the end of the shaft on a rivet 70. The rear spring 69 allows reversibility of the bolt 2 turns without tools as will be explained below. Figure 10 shows on the left the top rod slider 4A in the unlocked position and on the right the rod slider in the locked position. In the example chosen, the Y2 lathe bolt has determined dimensions that we want to be close to the products existing on the market. The thickness of the bolt Y2 turn is therefore substantially the same as the thickness of the top rod slider 4A and to allow the retraction of the bolt 72 turn 3 in the housing, the top rod slider 4A has in the upper part a shape in tune, with an enlarged part 72 allowing the arrangement of a

- 10 -

  longitudinal window 73 having a width authorizing the passage of the bolt Y2 round 3, and a terminal part comprising an oblong opening 75 used for the connection of the associated upper rod part. A connection light of the same type is also provided at the lower end of the bottom rod slide 5A. This figure shows the housing 9 and its cover 16. In order not to widen the housing due to the enlarged part 72 of the rod slide, the cover 16 and the housing 9 each include an opening 9A and 16A respectively, the dimension corresponds to the enlarged part 72 to which the travel of displacement of the rod slide is added, the walls of the enlarged part 72 flush with those of the housing and the cover being substantially in the same plane. Thanks to the window 73, the high rod slide 4A can be moved back and forth between its extreme unlocking positions (situation on the left in FIG. 10) and locking (situation of

  right of Figure 10), with the bolt Y2 extended out of the headrest 12.

  The top rod slider has a stopper 77 near the lower edge of the longitudinal window which prevents the retraction of the Y2 latch when the rod sliders are in the locked position, which increases the security conferred by the lock (see also

Figure 2).

  The enlarged portion 72 also has a greater thickness than the rest of the rod slider so that the latter is guided between a wall 128 protruding into the bottom of the

housing and headrest 12.

  The locking bolt 8 has the function of blocking the movement of the rods in the locked position in order to obtain the locked position of the cremone bolt. It is moved back and forth from the rear towards the front of the housing and vice versa under the action of a rotating bit 80 with which the barrel 2 is provided between a withdrawal position shown in FIGS. 1 and 2 and a active position shown in Figure 3 in which it blocks the movement of the top rod slider by being inserted below the latter. A part 82 called groove serves to immobilize the locking bolt 8 in these two extreme positions. The

  paneton 80 is used to lift the groove 82 to release the locking bolt.

  The groove 82 is disposed in the bottom of the housing 9.

- 11 -

  As best seen in Figures 6 and 7, the locking bolt 8 is provided with a front projection 84 with a planar upper surface 85 intended to serve as a stop at the lower end of the high rod slide when the latter is in the locked position (see Figure 3). In the lower edge of the blocking bolt is formed a cutout 87 which cooperates with the rotating bit 80 of the barrel. For this, the cutout 87 has a rear inclined wall 89 followed by a rear wall at a right angle 90, then a flat bottom 91 and symmetrically followed by a front wall at a right angle 92 and a front inclined wall 93, said walls. inclined being divergent in the direction of the opening of the cutout 87. The walls at right angles 90

  and 92 serve as drive stops for the rotating bit 80.

  On its upper edge 95 the locking bolt has rear 96 and front 97 grooves having a trapezoidal profile. The portion 99 of the locking bolt located between the two grooves 96 and 97 has a height reduced, for example by half, relative to the portions 99a and 99b bordering said grooves, so as to be able in particular to provide a lug 98 between the two grooves 96 and 97 without disturbing the crossed movement of the groove and the locking bolt which will be explained later. This lug 98 is intended to mesh a pinion 188 of the device for signaling the state of the lock which will also be described below. To simplify the figures and the explanation of the operation of the signaling device, lug 98 is in

  revenge shown in projection in Figures 1 to 3, 11 and 13 to 15.

  The groove 82 is provided with two front blockers 101A and rear 101B projecting perpendicularly from its upper edge 102 and having a trapezoidal profile complementary to that of the front 97 and rear 96 grooves of the locking bolt, so as to cooperate either either one with one of the grooves for

  lock the bolt in its two extreme positions.

  The groove has a rectangular opening 103, the planar upper face 104 of which is intended to come into contact with a bar protruding into the bottom of the housing perpendicular to the rear wall 60 of the housing and at a distance therefrom, said bar being inserted. in said opening. A spring 106 is disposed perpendicularly between the bar 105 and the groove 82. Its lower end is housed in a recess 108 provided in the flat lower face 109 of the opening in the groove and the upper end of the spring is housed in a housing (not visible in the figures) provided in the underside 112 of the bar 105. The spring 106 is in the compressed state so as to urge the groove in contact with the bar. In this position, one of the blockers 101 A or 101 B is embedded in one of the grooves 96 or 97 of the blocking bolt as will be explained below. To allow lifting and then lowering of the groove in contact with the bit 80 from one operating position to another, the lower edge of the groove has in the center a concave portion 139 forming a symmetrical lifting ramp in one or the other direction of passage of the paneton. The lowering of the throat is carried out under the return pressure of the

spring 106.

  The bar 105 projects through the rectangular opening 103 of the groove and serves as a rail cooperating with a slide 113a formed on the opposite face of the locking bolt to guide the lateral movement of the latter. Similarly, a slide 1 1 3b is formed on the other face of the locking bolt to cooperate with a rail

  formed in the housing cover.

  The housing 9 is manufactured by die-casting of a zinc / aluminum alloy known under the trade name or the brand <zamak ". Thanks to this technique, various walls, housings, raised area of material or openings can in particular be produced by projection in the housing so as to house and wedge the various elements of the cremone bolt and to guide their movement.

  This is the case of the bar 105 which has just been described and of the wall 128 for guiding the top rod slide which has been described.

also above.

  Likewise, a wall 120 is provided inside the housing parallel to the rear wall 60. Its front face 121 serves with the headrest 12 to guide the movement of the top rod slide and its rear face 123 serves with the rear wall 60 of the housing to guide the movement of the groove 82. The wall 120 is located in the housing so as to allow the projection to pass under its lower end 124

front 84 of the locking bolt 8.

  -13- The wall 128 for guiding the top rod slide extends parallel to the rear wall 60 of the shoemaker, its front face 129 serving to guide the movement of the high rod slide 4A and its rear face 130 serving as a support for the transmission bar 26 of the Y2 lathe bolt. The wall 128 also comprises at its lower end a housing 132 for a square nut cooperating with the fixing screw of the

housing 9 to the headrest 12.

  A wall 135 extends perpendicularly from the rear face 130 of the wall 128, the transmission bar 26 of the bolt 1/2

tower being located below.

  The walls 128 and 135 extend over the thickness of the housing. A recess 140, bordered by these walls is thus formed in the upper part of the housing, to advantageously allow the fixing of the cleanliness plates with a screw 141 to the joinery without causing dirt to fall inside the housing which risk seizing up

  the different actuation mechanisms.

  The rear wall 60 of the housing is provided in the upper part with an opening 131 allowing access from the rear of the housing to the shaft 67 of the bolt Y2 tower to allow its reversibility as will be explained below. From the rear wall 60 also extends perpendicularly a wall 136 whose length is such that a displacement stroke

  of the transmission bar 26 is arranged towards the rear of the housing.

  A boss 142 is provided in the bottom of the housing, under the wall 136, at a distance from the rear wall 60, to allow the perpendicular passage of the leaf spring 40 for indexing the handle, comprising a hole 11 for a fixing screw. of the housing and of the cover and a planar upper face 137 at a right angle serving to maintain the bent return of said leaf spring. The flat upper face of the boss also serves as a support for the rear end of the spring 57

  which urges the transmission bar towards the wall 128.

  In the lower part, the rear wall 60 of the housing is provided with an opening 150 which is provided to allow rotation of the bit 80 of the barrel 2. This feature makes it possible to advantageously reduce

the thickness of the housing.

  In the lower part of the housing is also provided a zone of material 152 comprising a housing 126 of shape corresponding to the oblong part 154 of the barrel intended to wedge the latter and a passage perpendicular to the headrest 12 passing through the housing 126 for

  receive the rod of a screw fixing the barrel 2 to the headrest 12.

  Parallel above the corridor 155 is formed a corridor 160 for receiving the rod of a fixing screw 13 of the housing to the headrest 12, a housing 161 being provided for a square nut. A bore 11 is also provided in the zone 152 perpendicular to the bottom of the housing for a screw for fixing the cover to the housing. The zone 152 includes a front edge 165 which is set back to allow the passage and guidance of the bottom rod slide 5A. The upper edge of the zone 152 has a flat part 166 at the front of the housing in contact with which the lower end 167 of the top rod slide 4A can come, and a circular part 168 up to the rear wall 60 of the housing which allows the rotation of the paneton 80 and in which

  1 5 opens the housing 126 for the oblong portion 154 of the barrel.

  Finally, under the follower is formed a cylindrical boss 182

  with a hole 11 for a screw for fixing the cover to the case.

  The various component parts of the housing, with the exception of the springs, are also made of an alloy of the type known under the brand "Zamak". This manufacturing technique advantageously makes it possible to obtain precise mechanical parts of smaller dimensions compared to the prior art. This allows

  in particular to clear a space 180 between on the one hand the half

  master 18 and auxiliary 17 and, secondly, the throat 82 and the

locking bolt 8.

  This space 180 is advantageously used to insert the device for visual signaling of the state of the lock which is now described with reference to FIGS. 11 and 12. The cylindrical outer surface of the boss 182 is used as a rotation shaft for the intermediate toothed pinion 100, which has been described above, which has a first level of engagement 100a with the toothed sector 33 of the auxiliary half-follower 17 and a second level b, on a larger diameter, of engagement with a pinion toothed 188. The first level 100a is guided in rotation by a shaft 184 cooperating with a circular opening 190 formed in the cover 16 of the housing. The intermediate pinion 100 extends over the

- 15 -

  height of the housing, its meshing portion 100b comprising a circular opening 190 engaged on the boss 182 thus serving as a rotation shaft. The pinion 188 is in two parts, a first toothed part 188a which cooperates with the second level 100b of the intermediate pinion 100 and a second part 188b which cooperates with the lug 98 of the locking bolt and which for this purpose has a groove 191 in arc of a circle and of trapezoidal section having front 192 and rear 193 drive edges (see FIG. 11) adapted to cooperate with the lug 98 of the locking bolt inserted in the groove 1 91. The second level 188b comprises a square opening 196 in which comes to engage the end of a rod of square section 197 carrying at its other end a rotary indicator 199 (also shown in elevation in FIG. 12), and an opening 189 is provided in the cover 16 for the passage of the square axis 197 of the rotary indicator 199. At its base, the part 88a is guided in rotation by a shaft 230 cooperating with a

  circular opening 231 formed in the bottom 60 of the housing.

  The two parts 188a and 188b are disengageable, similar to the two half-spindles, by means of a cam 195 projecting from the part 188b cooperating with a hollow sector 194 formed on the part 188a and of larger dimension than the cam 195. A return spring (not shown in the figures) allows, when the two parts 188a and 188b are assembled, to urge the cam 195 so that the lug 98 is located opposite the front edge 192 of the

  groove 191 (as shown in Figure 11).

  The rotary indicator 199 is fixed under the cleanliness plate 205 of the handle using a clipping element 200 to the joinery 201. It is divided into three sectors of three different colors, a sector V of representative green color from the unlocked open state of the cremone bolt, a sector J of yellow color representative of the locked state and a sector R of red color which with the color yellow is representative of the locked and condemned state. The size of the sectors is defined as a function of the angles of rotation which it is planned to have parts 188a and 188b of the signaling pinion perform when the cremone bolt changes state. Overall, the green sector V extends over a semi-circle, the other semi-circle comprising the yellow sector -16- J for 3/4 and 1/4 the red sector R. In the clockwise direction, we have the sector V, then sector R then sector J. An opening 209 is made in the cleanliness plate

  forming a display mask next to the indicator.

  The detailed operation of the cremone bolt and then of the

  signage is now described.

  The reversibility of the bolt 1/2 turn, so as to change the opening direction of the French window, is illustrated in Figure 5. It can be achieved without tools thanks to the presence of the rear spring 69 and the fact that the bolt 1/2 is mounted on a rotating shaft. If the cremone bolt is already attached to the French window, reversibility can be achieved by simply pulling the bolt 2 turns forward according to arrow F1, compressing the rear spring 69, then reversing the bolt 1/2 thanks to its rotary shaft 67 and by releasing the bolt Y2 which, under the effect of the rear spring 69, returns to its operating position. If the cremone bolt is not yet installed, one can also push the rear rivet 70 accessible through the window 131 from the rear edge of the housing, to compress the spring 69 and extract the bolt 2 turns. We can also

combine these two actions.

  Figure 1 shows the cremone bolt in the unlocked position. The top rod slider 4A is retracted into the housing while the bottom rod slider 5A has its connection end with the second part of the low rod exiting the housing. The locking bolt

  8 is immobilized by the groove 82 against the rear wall 60 of the housing.

  This situation corresponds to Figure 6 and as shown in dotted lines the rear blocker 101B is embedded in the rear groove 96 of the locking bolt. The front blocker 101A is located in front of the front groove 97 opposite the upper flat surface of the projecting part 84 of the locking bolt. The Y2 lathe bolt is in the extended position, closing the French window. The return spring before 68 of the bolt 2 is decompressed as well as the return spring of

the handle 57.

  The unlocked French window is opened by lowering the handle which has the effect of turning the half-nut

  master 18 along arrow F1 of figure 1. Finger 25 of the half

  follower then comes to bear against the front face 62 of the -17inferior end 55 of the transmission bar 26, which has the effect of compressing the return spring of the handle 57 formed behind the transmission bar and the front spring 68 formed around the Y2 latch rotation shaft at the front of the bar. We find ourselves in the situation of Figure 4. In the unlocked position, the position of the cams corresponds to a superposition of Figures 8 and 9. We understand that when the cremone bolt was opened, the cams 45a and 45b were inactive. They moved in the recesses 44a and 44b respectively. The auxiliary half-follower 17 has therefore not been driven. The spaces of freedom present in the recesses have been consumed. When the handle is released, the springs 57 and 68 return the handle to the rest position until the boss 41 of the indexing spring 40 is found in

  the indexing notch 27 of the master half-follower 18.

  i15 The locking of the cremone bolt takes place by raising the handle which has the effect of rotating the master half-nut 18 towards the rear of the housing according to the arrow F2 in FIG. 1. The cams 45a, 45b are

  in this active case, in abutment against the cams 41a, 41b, and the half

  auxiliary follower 17 is also rotated along arrow F2. The toothed sector 32 then meshes with the bottom rod slider downwards, the reversing pinions 21 and 21 ′ jointly moving the high rod slider upwards. We find ourselves in the position of FIG. 2: the upper end of the top rod slider has reached the top of the housing while the lower end of the bottom rod slider is found well outside the housing. The retraction of the 1/2 turn latch is blocked by the ascent of the stopper 77 formed on the high rod slide behind the Y2 turn latch. It is then no longer possible to retract it even by pushing it

outside by hand.

  The locking mechanism is locked in place by giving a turn of

  key in barrel 2 which has the effect of rotating the bit 80.

  This first raises the groove 82 by interacting with the rear of the ramp 139 so that the blocker 101B is completely disengaged from the groove 96 of the locking bolt and the latter is released. Secondly, the paneton comes into contact

  with the wall 92 of the cutout 87 of the locking bolt and pushes it

  - 18- towards the front of the housing until it finds itself in the situation in FIG. 3 o the front projection 84 of the locking bolt is inserted under the top rod slide. Conjointly the paneton is found on the front of the ramp 139 of the groove which causes its lowering under the thrust of the spring 106 until the immobilization of the locking bolt again. We are then in the situation of FIG. 7. This time, it is the front blocker 101A which is fitted into the front groove 97 of the blocking bolt, the rear blocker 101B

  located at the rear of the locking bolt.

  The unlocking of the cremone bolt takes place by the reverse movement of the pin and in the same way as previously thanks in particular to the symmetry of the cutout 87 of the locking bolt and of the

ramp 137.

  Unlocking, like opening the door, is effected by pressing the handle, which has the effect of moving the half-nut

  master according to arrow F3 in FIG. 3 towards the front of the housing. The half

  master follower acts on the transmission bar to retract the bolt

  Y2 turn and in this case the cams 45a and 45b are active and the half

  auxiliary follower 17 is driven so that the rod slides

  are retracted to return to their unlocked position in FIG. 1.

  The operation of the device for signaling the state of the lock is now explained with reference more particularly to FIGS. 13 to 15 in which the viewing window 209 and the rotary indicator 199, the sectors are also shown in elevation.

  not visible through the window 209 being marked with dotted lines.

  Figure 13 shows the cremone bolt in the unlocked position, the locking bolt is behind the housing. Through the window 209 of the cleanliness plate 205 it is the green sector of the rotary indicator which

is visible.

  The locking of the rods causes the toothed sector 33 of the auxiliary half-follower to move towards the rear of the housing according to arrow F4, which causes the rotation of the intermediate toothed pinion, according to arrow F5 itself causing the rotation of the part 188a of the signaling pinion 188 to which it is controlled. This is in the situation in FIG. 14. During this operation the cam 195 moves in the hollowed-out area 194 of the part 1 88b without driving it in rotation. The rotation of the part 1 88a of the pinion causes the indicator 199 to rotate through its square rod 1 96 so that it is the yellow sector J which is now visible at

  through window 209 of the cleanliness plate.

  The lock is then locked by moving the blocking bolt towards the front of the case according to arrow F7. The lug 98 in contact with the front edge 191 of the recess 192 drives the rotation of the second part 188b of the signaling pinion 188 and jointly of the first part 188a and of the indicator 199 according to the arrow F8 in a direction opposite to the previous case. The red sector R is now visible through the window 209 at the same time as the remaining part 221 of the sector

  yellow. We are in the situation of figure 15.

  Unlocking and unlocking the cremone bolt

  are performed by reverse operations.

  Thus, a signaling of the state of

  the cremone bolt controlled by the movements of the handle and the barrel.

  It goes without saying that alternative embodiments are possible, in particular the rods can be made in one piece. Furthermore, provision may be made for bringing an indicator provided with a fixed display mask to the cleanliness plate instead of

integrate it below.

  Furthermore, an electrical variant of the device for signaling the state of the lock is also possible. It is schematized on

Figures 16 to 19.

  In this variant, there are no intermediate gears 100 and 188, nor lug formed on the locking bolt. At the location of the pinion 188, there is provided a connector 210 comprising a rod of square section 211. For the display of the state of the lock, a display plate 212 with three diodes 213a, 213b and 213c is used. different colors of LED / LCD type, each representative of a state of the lock, said plate being attached to the cleanliness plate for example above the handle and a hole being made in the cleanliness plate and the joinery for the connection to the housing. Each diode 213a, 213b and 213c is thus connected by two wires on the one hand to a lithium battery 217 and on the other hand

- 20 -

  to an electrical contact terminal, respectively 214a, 214b, 214c,

  formed on one of the four faces of the square axis 211 of the connector.

  On the fourth face is provided a common terminal 214. Each terminal 214a, 214b, 214c is moreover connected by a wire, respectively 215a, 215b, 215c to a fixed micro-contact respectively 220a, 220b, 220c arranged in the space 180 so as to cooperate each in turn with a movable lug. The first movable lug 216a corresponding to the unlocked state is arranged on sector 33 of the auxiliary half-follower 17, near its rear end, and the corresponding fixed microswitch 220a is located towards the rear of the housing so that when the demi-fououots

  are in the rest position, contact is established (as in Figure 1).

  The second movable lug 216b corresponding to the locked state is disposed on sector 32 of the auxiliary half-follower 17 on its rear edge 222 and the associated fixed micro-contact 220b is located at the end of travel of sector 32 towards the rear of the housing. The third movable lug 21 6c is located at the front of the upper edge 95 of the locking bolt and the corresponding fixed micro-contact 216c is located at the end of the travel of the locking bolt in the locking position of the rod slides on the rear face. of the wall 120. Each micro-contact has a wire 222a, 222b, 222c for connection to the common terminal 214

of connector 212.

  The operation of the device is as follows. In the unlocked position, corresponding to FIG. 17, it is the lug 216a at the end of the sector 33 which is in contact with its microswitch 220a. The corresponding green diode 213a is thus lit. When the cremone bolt is locked by lowering the handle, the sectors 32 and 33 of the auxiliary half-nut are offset towards the rear of the case. We find ourselves in the situation of Figure 18: the pins have been moved; The lug 216a is no longer in contact with its micro-contact 220a but it is now the lug 216b which is in contact with its micro-contact 220b causing the corresponding orange diode to light up. And finally, when we lock the cremone bolt, as shown in Figure 19, it is the lug 216c of the locking bolt which comes into contact with its micro-contact 220c and the red diode lights up

  in addition to the orange diode or in place of the latter.

  -21 - As a variant, it is possible to provide a single multicolored diode reproducing the three colors. It can also be provided that the energy is supplied by the supply of a rolling shutter with which the French window would be fitted. Furthermore, the display plate can be fixed under the cleanliness plate in which one or more holes will be made

next to the diode (s).

  There is also an electronic variant of the lock status signaling device in which a light signal is provided on a CAD remote control device capable of transmitting the status of the lock by radio link to a receiver signaling unit. centralized comprising means for displaying said state. Signal transmission can also be done using wires, infrared or by carrier currents delivered by the electrical network. With such a system, the user can thus advantageously at a glance on a housing

  check the condition of its locks for example before going out.

  It can also be provided that the signal representative of the state of the lock is also transmitted to a centralized alarm management device, means for processing data representative of the state of the lock being provided in said housing for determining an instruction to trigger said alarm. When the user wants to activate his alarm, the device will check that the locks are closed, which will be one of the best guarantees of security. The present invention, thus thanks to this system, makes it possible to reduce the risks of burglary, since the information according to which a door or a French window has been fractured will be transmitted to the alarm unit, even before conventional detection of presence.

or shock.

  The representative signal can also advantageously be transmitted to a device managing the shutdown of the heating in the event, for example, of prolonged opening of the French window, the instruction for stopping electric convectors can in particular be transmitted by the carrier currents or by the one of the means of transmission

mentioned above.
