Description

LOCK ASSEMBLY WITH ACTIVITY TRI NG

The invention relates to a lock assembly with actuating rods.

It would be useful to have a lock assembly with an increased level of security (first aspect).

A second useful aspect (in addition to the first aspect or replacement) would be to have a set of motorized lock with an increased level of security, especially so that in case of power failure the motorized lock assembly is configured so that the opening on which is installed the assembly provides the firewall function.

It could also be useful to have a lock assembly that can be operated in several ways or in several independent actions such as by a motor system, a crutch and a key (third aspect in addition to or in replacement of the one or both of the above aspects). The invention relates to a lock assembly which satisfies at least one of the above aspects. This lock assembly comprises: at least one first housing comprising at least one bolt and at least one half-turn which are each adapted to adopt an extended and / or retracted position, two actuating rods which are able to move independently of one another, one said bolt rod being configured to actuate the deployment or retraction of said at least one bolt, the other said half-turn rod being configured to actuate the deployment or retraction of said at least one bolt a half-turn, a second housing comprising at least one drive system of the two actuating rods.

Such a lock assembly allows, thanks to the independent rods in their movement, to separately control the deployment or retraction of said at least one bolt and said at least one half-turn. This set also makes it possible to sequence the movements to the reclosing of the opening on which is installed all. When the opening opens the half-turn rod is first actuated (for example by a motor system). When the door closes the rod bolt is actuated (for example by a motor system) to automatically relock said at least one bolt, thus obtaining a high level of security with this lock assembly. The two aforementioned actuating rods can act directly on said at least one bolt and said at least one half-turn respectively, or through one or more other rods or actuating elements. For example, each actuating rod can act itself on another actuating rod which acts directly on said at least one bolt or said at least one half-turn depending on the rod concerned.

According to other possible characteristics taken separately or in combination with each other: the assembly comprises an electromagnetic effect connecting mechanism of the two bolt and half-turn actuating rods which, when activated, makes the two actuating rods integral with one another and, when it is deactivated, makes the two actuating rods mechanically dissociated from each other; the half-turn rod can be released in case of power failure and ensures the reclosing of the opening on which the lock assembly is installed, without the need for a backup battery to complete the task of reclosing of a motor system and return to a position where said at least one bolt is deployed; at least one drive system of the two actuating rods comprises at least one of the following three drive systems: a motor drive system, a drive follower drive system and a drive train; cylinder drive system; the lock assembly can thus be used in three different ways: by motorization to carry out a conventional access control, by a key for an entrance generally from outside the room which is closed by the opening on which is installed the lock assembly, by a maneuvering member (such as a stand) disposed on the inner side of the door, the latter mode of use of the lock assembly is in particular provided on an escape route so that the output is always possible even in case of power failure; the motor drive system comprises: a motor, a driving rod which is driven in displacement by said motor and which is engaged with the actuating rod bolt; this mode of use of the lock assembly is the most used because it is a motorized lock assembly; the motor drive system is configured to drive: the drive rod, the actuating rod bolt engaged with the drive rod, and the half-turn actuating rod which is secured to the actuating rod bolts by effect electromagnetic, thereby causing the retraction of said at least one bolt and said at least one half-turn; the half-turn actuating rod is subjected to the action of return means which tend to bring it back into an extended position in which the at least one half-turn is deployed when the electromagnetic binding mechanism of the two rods latch and latch actuation is disabled; this arrangement is useful for actuating the half-turn actuating rod in case of power failure (release of the rod) and thus ensure the reclosing of the opening on which is installed the lock assembly and therefore the maintenance of the firewall function; the return means are elastic means; the actuator follower drive system and the cylinder drive system each comprise a disengagement mechanism which is actuated, as the case may be, by a rotational movement of the follower or cylinder in a first angular stroke in rotation and which disengages the actuating rod bolt engaged with the drive rod; the disengagement maneuver is easy (the start of movement of the follower or cylinder corresponds to a "dead" stroke) and, after disengagement, the opening force to the follower (via the operating member such as a crutch) or to the cylinder (via a key) is easy; the drive follower drive system comprises a first drive mechanism for the two half-turn actuating rods and bolt which is actuated, following the disengagement of the actuating rod bolt from the drive rod, by continuing the rotational movement of the follower following a second angular travel in rotation of said follower; following the run of the follower can drive the rods latch and bolt to cause the retraction of said at least one bolt and unlocking the lock assembly to the follower (via a crutch) and, therefore, the opening of the opening to which it is subject (in the presence or in case of power failure); the first drive mechanism of the two half-turn and bolt actuating rods comprises a drive lever which, by continuing the rotational movement of the follower following the second angular stroke, is rotated to cooperate simultaneously with the two actuating rods turn latch and bolt and drive them in a translational movement; the two rods are mechanically driven because, even in the event of a power failure, it must be possible to open the door by maneuvering the operating member such as a stand so that the exit is always possible on an escape route; the cylinder drive system comprises a second drive mechanism for the two half-turn and bolt actuating rods which is actuated, following the disengagement of the actuating rod of the driving rod, by the continuation of the movement; rotation of the cylinder following a second angular stroke of rotation of the cylinder; following the stroke of the cylinder allows to drive the rods latch and bolt to cause the retraction of said at least one bolt and unlocking the lock assembly to the cylinder (via a key) and, therefore, the opening of the opening to which it is subject (in the presence or in case of power failure); the second drive mechanism of the two half-turn and bolt actuating rods comprises at least one cylinder rod which is configured to be driven in translation by the continuation of the rotational movement of the cylinder following the second angular rotation stroke of the cylinder; and to drive, in turn, simultaneously the two actuating rods half-turn and bolt via a drive member; the two rods are driven to unlock the lock assembly to the cylinder (via a key) and, therefore, the opening opening to which it is subject (in the presence or in case of power failure); the drive member is for example carried by the rod cylinder or by a part connected to it; at least one roller rod is configured, on the one hand, to occupy a first position in which the at least one roller rod is engaged with a fixed element of the lock assembly and, on the other hand, to occupy a second position in which it is disengaged from the fixed element and is then configured to be driven in translation, the second drive mechanism of the two actuating rods half-turn and bolt comprising a disengagement mechanism which is configured to disengage said at least one cylinder rod of the fixed element during the first angular displacement in rotation of the cylinder, said at least one roller rod being driven in translation by the second angular rotational stroke of the cylinder, this arrangement represents a mechanism for unlocking the cylinder; lock assembly via the cylinder of the latter which is particularly reliable and secure; this mechanism is independent of the engine; the aforementioned disengaging mechanism may comprise a part movably mounted on said at least one roller rod: the moving part is able to occupy, on the one hand, a first position in which it cooperates with the fixed element of the assembly lock and said at least one roller rod is then in the engaged position and, secondly, a second position in which it no longer cooperates with the fixed element of the lock assembly and said at least one roller rod is then in the disengaged position and free to move in translation; the moving part carries for example the drive member which is configured to move the bolts and latch rods during displacement of the roll rod; in general, the lock assembly may comprise a cam which is rotated by the rotation of the cylinder (for example by a mechanism or gear system) and which, when rotating during the first rotary angular stroke, of the cylinder, cooperates with the moving part to move it from the first position to the second position. Other features and advantages will become apparent from the following description given solely by way of nonlimiting example and with reference to the accompanying drawings, in which: FIG. 1 is a general schematic view of an equipped door a lock assembly according to one embodiment of the invention; FIG 2 is a schematic perspective view of the two actuating rods bolt and half-turn of the housing 24 of Figure 1; FIG 3 is a schematic side perspective view of the two actuating rods bolt and half-turn of the housing 24 of Figure 1; FIG 4 is an exploded perspective view of the bolt rod disposed on one of its flanks with different members mounted on its opposite side; FIG. 5 is another perspective view of the assembly of the rods and the mechanism for opening to the follower; FIG. 6 is a view of the assembly shown in FIG. 5 taken on the side of the side opposite to that shown in FIG. 5; FIGS. 7 and 8 are successive views of the assembly of FIG. 6 showing different angular races of the follower; FIGS. 9 to 11 and 14 represent, in front view, all the parts forming a cylinder drive system; FIG. 12 is an enlarged perspective view of a roller rod and a driving part of the bolt and half-turn rods carried by the roller rod; FIG. 13 illustrates schematically and partially the support against which the roller rod is slidably positioned; FIG 15 is a partial enlarged view of the edge of all the actuating rods.

As shown schematically in Figure 1 and designated by the general reference denoted 10, an opening such as a partially shown door is equipped with a lock assembly 12 according to one embodiment of the invention. The lock assembly 12 generally comprises (in an example of a minimum version): a first housing or trunk 14 which comprises at least one bolt (safety bolt which is for example a hook or a round bolt) 16 ( in this example only one bolt is present) and at least one half-turn 18 (in this example a single half-turn is present) which are each adapted to adopt a deployed and / or retracted position relative to the housing and the door 10, two-actuating rods 17, 19 which are able to move each independently of one another, -a second housing or trunk 24 which comprises two other actuating rods 20, 22 (visible in perspective on Figure 2 which partially illustrates the housing 24 whose formwork has been removed) respectively connected to the rods 17, 19 (for example by interlocking) and which are able to move each independently of one another. The second housing 24 also comprises at least one drive system of the two actuating rods 20, 22 which in turn drive the two rods 17, 19. The rods 17, 19 are arranged between the housings and will be called thereafter inter-housing rods. In a variant not shown the lock assembly may comprise only two actuating rods which replace all of the rods 17, 19, 20, 22. The shapes of the rods may also vary without their main function being changed. One of the two rods 20, 22 of FIG. 2 is a bolt rod 20 and is configured to actuate the deployment or retraction of the said at least one bolt 16 in cooperation with the inter-casing bolt rod 17. The actuation The driving of the rod 20 causes the actuation / driving of the rod 17 to which it is mechanically linked. The other rod is a half-turn rod 22 which is configured to actuate the deployment or retraction of said at least one half-turn 18 in cooperation with the inter-housing turnbuckle 19. The actuation / training of the rod 22 causes the actuation / driving of the rod 19 to which it is mechanically linked. The actuation / driving of the rods causes the deployment or retraction of said at least one bolt or said at least a half-turn depending on the rod which is driven by the drive system.

Note that the same housing 14 may comprise both one or more bolts and one or more half-turn or a single bolt and a single half-turn or one or more bolts or one or more half-turn.

One or more other boxes of this type not shown can alternatively equip the door 10. Thus, the lock assembly 12 may comprise a housing comprising one or more bolts and another housing comprising one or more half-turn. Alternatively at least one of the housings may comprise both one or more bolts and one or more half-turn.

In Figure 1 the rods 17 and 19 are shown parallel and laterally spaced from each other to be able to view them while in practice they can, for example, be superimposed one above the other in being facing the door and a single rod should normally be visible in Figure 1. The rods 20 and 22 are also shown one above the other and contiguous. Other configurations of the rods are conceivable.

The various views that will be described below represent sets of parts, mechanisms and other mechanical systems that are integrated in the housing 24 of Figure 1. The housing is not shown in these figures or only part of it is shown as in Figure 2. The sets of parts, mechanisms and other mechanical systems are connected to the housing and are for example mounted on axes, some of which are illustrated in Figure 2. However, in general, in the views of which the description follows the fixing elements / connection to the housing will not be represented or described because they are conventional elements known to those skilled in the art.

FIG. 2 illustrates in perspective the set of two rods 20 and 22 superimposed flat and linked in translation by means of pins 23 integral with one of the rods and which are engaged and free to slide inside lights 25 practiced in the other rod. In this example the pins 23 are subject to the rod bolt 20 and the lights 25 are formed in the half-turn rod 22. According to a variant not shown, the opposite is possible. The set of two rods which are configured to slide freely relative to each other (parallel to the Z axis of FIGS. 1 and 2) is fixed to a plate 30 of the housing 24.

3 illustrates in perspective in a side view (the plate 30 of FIG. 2 has been removed), on the one hand, all of the two rods 20 and 22 arranged vertically on the wafer and, on the other hand, a mechanism 32 for binding by electromagnetic effect of the two rods. This mechanism (eg electromagnet) makes it possible, when it is activated, to make the two actuating rods 20, 22 integral with each other in axial translation and, when it is deactivated, to mechanically dissociate the two actuating rods from each other.

The mechanism 32 comprises two parts 32a, 32b which are each connected to one of the two rods 20, 22. One 32b of the two parts is made of a magnetizable magnetic material. Part 32b is axially movable relative to the other fixed part 32a and is attracted magnetically by this other part when an electric current is applied in the fixed part 32a and creates a magnetic field in the latter. Thus, in the presence of electric current in the portion 32a, the two parts 32a and 32b are bonded or "glued" to one another by electromagnetic effect and are therefore indissociable mechanically from each other. When the current is cut off, the electromagnetic effect ceases and the two rods are again mechanically independent in their translational movement.

In this example, the portion 32a is integral with the latch rod 20, while the other movable portion 32b is integral with the half-turn rod 22. However, the reverse arrangement is also conceivable.

The drive system of the two actuating rods 20, 22 (and therefore of the two rods 17, 19) comprises, in the embodiment described, the following three systems or drive means: a system of motor drive, -a follower drive system for operating member (the operating member can be a crutch, a pallet, a panic bar ...), - and a drive system cylinder or barrel for actuation via a key.

Note that in other embodiments not illustrated here, the drive system of the two actuating rods 20, 22 may comprise only one of the systems listed above (the motor system, the system or the cylinder system) or two of these systems (the engine system and the follower system or the engine system and the cylinder system or the follower system and the engine system).

We will now describe a motor drive system of the lock assembly.

FIG. 3 also shows a third rod 34 called a driving rod which is driven in displacement (translation in the same axial direction as the rods 20, 22) by a motor 36. According to a variant not shown, the driving rod is driven by via an electromagnetic linear actuator.

The motor 36 is connected to the drive rod 34 via, successively, a gear train with perpendicular axes 38 which comprises a wheel 38a carrying a pinion 38b, and a rack 40 (arranged on one end). two opposite edges of the rod) in which engages the pinion 38b. The rotation of the motor (controlled for example by an external access control system not shown such as a badge reader ...) makes it possible to move the motor rod 34 in axial translation.

The driving rod 34 is engaged with the actuating rod bolt 20 via a clutch which, here, is formed by a drive finger 42 integral with the rod 20 and which is engaged in a groove 44 of the rod 34 (fig.3). The reverse arrangement can be envisaged.

As shown in Figure 4, the bolt rod 20 carries a part 46 which is fixed on one 20a of the two opposite sides of the rod by a mechanical fastener 48a. The piece 46 is resiliently pivotally mounted along the sidewall 20a by means of an elastic element such as a spiral spring 50. The part 46 is thus pivotable as indicated by the arrow F around the axis of rotation. rotation / pivot 48a. A guide pin 48b fixed to the side 20a and engaged in a slot 46a of the piece 46 serves as a guide during the pivoting movement of the piece. The spring 50 is fixed to the side 20a by a fastener 48c and is held in position at its two opposite ends respectively by a stop 48d fixed directly to the side 20a and a boss 46f of the piece 46. The action of the spring under the boss 46f exerts a permanent effort on the piece 46 which tends to maintain it in the high position. The pivot 48a fixes an end 46b of the piece 46 to the sidewall 20a. An element 48f is fixed to the sidewall 20a near the opposite end 46c of the piece 46 and caps the end 46c to ensure that it is held flat against the sidewall 20a.

The drive finger 42 extends from a lower edge 46d of the piece 46, perpendicularly to the large face of said piece 46 and away from it and the flank 20a. The finger 42 thus forms a projection relative to the flat piece 46.

In view of the foregoing, the motor drive system shown in FIG. 3 is configured to drive: - the drive rod 34 via the gear train 38 and the rack 40, - the actuating rod bolt 20 which is engaged with the drive rod 34 via the finger 42 in axial stop in the groove 44 (the piece 46 is held elastically in the upper position so that the finger 42 fits into the groove and is held against the bottom of the groove; in FIG. 3 the piece 46 projects upwards beyond the upper edge of the rod 20), and the half-turn actuating rod 22 which is secured to the actuating rod 20 by electromagnetic effect via the connecting mechanism 32, thus causing, via the rods 17 and 19, the retraction of said at least one bolt 16 and said at least one half-turn 18 and thus the opening of the door 10 (FIG 1) .

Means or return members of the half-turn actuating rod 22 are present in the lock assembly 12. These means have the function of bringing the rod 22 (by sliding it axially) into an extended position in which said at least one half-turn 18 is deployed when the electromagnetic effect connecting mechanism 32 of the two bolting and half-turn actuating rods is deactivated (no current) and the two rods 20 and 22 are thus again independent in their displacement. The bolt rod 20 remains, in turn, in a fixed position engaged with the driving rod 34.

As represented in FIG. 5, these means or return members are, for example, resilient means or members 60 (eg spring (s)) which exert on the rod 22 a restoring force in the direction indicated by the arrow R and which removes part 32b from part 32a of connecting mechanism 32.

We will now describe with reference to Figures 5-8 a follower drive system for operating member such as a crutch. Alternatively, the operating member may be a pallet. This system is independent of the motor drive system and allows to unlock the lock assembly (retract bolts and latch (s)) and thus open the door at any time, especially in case of power failure.

In order to be able to unlock the lock assembly independently of the motor, this drive system comprises a disengaging mechanism which is actuated by a rotational movement of the follower in a first angular rotational stroke and which makes it possible to disengage the actuating rod 20 engaged with the motor rod 34.

Figure 5 shows a set of parts comprising a follower 70 which includes a female square 72 for receiving a conventional stand not shown. The stand allows to rotate the follower 70 about its axis which is perpendicular to the flanks of the rods (and the plane of Figure 6 which will be described later). A follower spring 73 is mounted around a rod 74 and the follower is thus mounted resiliently support to be held elastically in the position of Figure 5 when the support on the stand stops. In case of support on the stand, the spring 73 is compressed.

The follower 70 carries on one side an element 76 which is mounted around a guide and abutment member 78 (eg guide cylinder). The element 76 has an external toothing 76a forming an angular sector which meshes with a pinion 80. In this example the element 76 has a generally false shape with a toothed arm whose hollow is wound around the element guide and stop 78. Other forms are alternatively possible. The set of parts also comprises a piece 82 forming a cam and rotatably mounted about an axis perpendicular to the plane of FIG. 5. All the parts shown in FIG. 5 are rotatably mounted about axes parallel to one another (These axes are perpendicular to the plane of Figure 6).

As shown in FIG. 6, the pieces of FIG. 5 are seen from the opposite side (face hidden in FIG. 5). Thus, the cam member 82 includes a center pinion 82a and a portion of its outer periphery (on an angular sector) is configured to form a cam 82b. In the example described, the cam shape is formed by a flat shape. The part 82 is configured and mounted in the assembly of parts so that its cam-shaped periphery 82b is in contact with the upper edge 46e (FIG 4) of the piece 46 in order to act on it and to cause its displacement (lowering the movable part 46 in FIGS. 3 and 4).

In FIG. 6 the follower 70 has not yet been maneuvered and the two actuating rods 20 and 34 are always engaged with each other by means of the finger 42 engaged in the groove 44.

When pressing on the stand, the follower rotates (FIG. 7) according to a first angular rotation stroke (in the direction indicated by the arrow FO), which has the effect of causing rotation of the toothed element 76, pinion 80, central pinion 82a and cam 82b. In Figure 4 the upper edge 46e has a cut / crenelated shape while in Figures 6 to 8 the shape has been shown rectilinearly for the sake of simplification. However, the respective shapes of the peripheral portion 82b and the upper edge 46e may vary to the extent that the cooperation between these two forms, during the rotation of the piece 82 (as in Figure 7), allows to move the piece 46 relative to the drive rod 34 and out the finger 42 of the groove 44. In the position of Figure 7, the finger 42 therefore no longer serves as an axial stop in the groove 44 and the two rods 34 (motor) and 20 (bolt) are no longer engaged with each other (disengaged position). The bolt rod can be freely driven independently of the drive rod.

The mechanism that has just been described is therefore a mechanism that allows to disengage the rod bolt 20 of the drive rod 34.

On the side of the follower 70 which is opposed to that carrying the element 76, the follower is provided with a series of teeth 70a which meshes with the teeth of a pinion 84 which, themselves, meshes with the teeth of a pinion 86a carried by one of the faces of a workpiece 86. The workpiece 86 is called a coach and has the function of driving in rectilinear translation all of the two actuating rods bolt 20 and half turn 22 when they are no longer mechanically associated with the drive rod (disengaged position of the rod bolt 20). The piece 86 carries a drive lever 86b (or drive finger) which is arranged opposite the rods 20 and 22. The rods have cut edges so that the lever 86b is facing a shoulder (in Figure 7 only the shoulder 20b of the rod 20 has been shown, the corresponding shoulder of the rod 22 is hidden because it is placed behind the rod 20).

During the first angular disengagement stroke (FIG. 7), the driver 86 has rotated (see the arrow illustrating the rotation of the lever 86b) and has moved closer to the shoulders of the rods 20 and 22 placed in the trajectory of the lever 86b. . The coach, however, has a race "dead" in that it does not yet perform its function of training rods.

When the support movement on the stand continues, the follower continues to rotate about its axis (arrow F1 in Figure 8) of rotation, the lever 86b continues to rotate (arrow F2) and engages simultaneously with the shoulders rods 20, 22 to drive in translation along the arrow F3. The finger 42 out of the groove 44 bears against one of the edges of the drive rod 34 and slides along it. This drive in translation also causes the translation of the rods 17 and 19 of Figure 1, which allows to unlock the lock assembly (retraction bolts (s) 16 and half-turn 18) and thus to open the door. The driving rod 34 remains, in turn, in a fixed position, because the rod bolt is always in the disengaged position.

Note that the two rods 20, 22 are still electromagnetically linked by the connecting mechanism 32 in this operating mode of opening to the stand as the electric current is present ..

When the support on the stand is released, the follower 70 returns to its initial position under the counteracting action of the elastic element 73 mounted on the rod 74. The parts of the set of parts of FIG. disengaging mechanism (parts 70, 76, 82 with the exception of the part 46 connected to the rod 20) and the driving mechanism of the rods (parts 70, 84, 86) return to their initial position of FIG. The bolt rod 20 remains, in turn, in the deployed position while the half-turn rod 22 is resiliently biased (deployment of the half-turn) under the action of the elastic means 60 (Figure 5). The two rods 20, 22 are mechanically dissociated from each other because when the door 10 opens a sensor (eg magnetic) not shown detects the open position, which controls the power cut in the mechanism 32 and so its deactivation. The U-turn (s) of the housing 14 are deployed and the door can then be closed again.

In this position the finger 42 is always outside the groove of the drive rod 34 (disengaged position) and resting on the edge thereof. The opening can be performed identically with another actuator such as one of those listed above, or another.

A cylinder drive system will now be described with reference to FIGS. 9 to 15. This system is independent of the motor drive system and makes it possible to unlock the lock assembly (retractation of the bolt (s) and a half-turn (s)) and therefore open the door at any time.

The cylinder drive system comprises a first disengagement mechanism of the actuating rod bolt 20 of the driving rod 34. The lock assembly 12 comprises a conventional cylinder (not shown) provided with a paneton in its lower part. and the housing 90 is shown in Figure 9. In Figure 9 the follower 70 has only been shown to show its position relative to the cylinder drive system. The follower 70 does not touch the teeth of the crown 98 which are however very close. A first ring gear 92 toothed on its outer periphery partially surrounds the housing (and therefore the cylinder) and is rotated about an axis perpendicular to the plane of Figure 9 when a user enters his key into the cylinder. A lock block provided with a plate 93 with the outer cutout of the housing 90 is shown in FIG. 9.

This ring 92 cooperates with two satellites 94, 96 arranged symmetrically above the ring 92 and which each cooperate with a second ring 98 of continuity. The continuity ring 98 carries, on the one hand, on one of its faces a pinion 100 with several pins (for example five in this example) and, on the other hand, on its opposite face (FIG. 102. The function of the cam 102 is to make contact with the upper edge 46a of the rotating / pivoting piece 46 and to release the finger 42 from the groove 44 of the driving rod 34 (in the direction of the horizontal arrow). in FIG. 10) following a first stroke of rotation of the cylinder (in the direction of the curve arrow in FIG. 10) in order to disengage the bolt rod 20 from the driving rod 34. The disengagement is carried out as already described with reference to the preceding figures but with means s / different mechanisms. In the disengaged position, the bolt rod 20 is no longer secured to the driving rod 34.

During the rotational movement of the cylinder, the pinion 100 co-operates simultaneously with another set of elements or mechanism for driving the bolt and half-turn rods, which will now be described with reference to FIGS. 11 and following.

The drive mechanism more particularly comprises a rod cylinder 110 whose sliding (axial translation) will allow to simultaneously drive in translation the two rods 20, 22.

The drive mechanism of the two rods 20, 22 comprises a mechanism for disengaging the cylinder rod 110 from a fixed element of the lock assembly (element 140 in FIG. 13) which is actuated during the first angular stroke in rotation of the cylinder as described above for disengaging the bolt rod.

As shown in FIG. 11, the roller rod 110 is slidably mounted axially on a fixed support 140 of the lock assembly shown in FIG. 13 (such as a cover). The rod 110 is mounted on the support by means of guiding pins 112 sliding in grooves 114 of the rod (FIG 11). The rod 110 is also provided with a portion which carries on one edge a plurality of meshing teeth 116 intended to cooperate with the pans of the pinion 100 for the translation drive of the rod 110.

A piece 118 is rotatably mounted relative to the rod 110 along a 110a of its two opposite flanks. FIG. 12 illustrates in an isolated manner the moving part 118 on the opposite side to that illustrated in FIG. 11. The part 118 is thus mounted articulated in rotation by an end 118a fixed to the rod 110. The piece 118 rests on an element resilient 120 (such as a coil spring) attached to the sidewall 110a by a support 121 and which tends to push up the workpiece so that it is held in the up position of FIG. 12 (first position of the moving part 118) and that it hides the teeth 116. In this position (it is also the position of FIG. 11) the teeth 116 are not accessible to the bonnet of the pinion 100. The roller rod is in a position engaged with the support fixed 140 of the lock assembly shown in Figure 13 and can not be moved in axial translation.

More particularly, the piece 118 carries a drive finger 122 on its face opposite that facing the rod 110 and extending perpendicular to the face of the workpiece 118. This finger 122 bears on the elastic element 120 (eg spring), in particular on one of the ends thereof. This finger 122 forms a drive member which will be used to drive in axial translation rods 20 and 22, for example by pushing axially.

As shown in FIG. 11, a pin 130 is carried by the face of the piece 118 which is opposite to that bearing the finger 122. This pin 130 is engaged in a groove 132 (perpendicular to the axial direction of translation of the rods) practiced in the thickness of the rod 110 and is slidable in this groove when the moving part 118 is lowered.

FIG. 13 illustrates a portion of the fixed support 140 on which the rod 110 is mounted and slidably mounted. A light 142 (aligned in the axial translation direction of the rods) made in this support reveals the perpendicular groove 132 and the rod 110.

FIG. 14 illustrates the assembly described in FIG. 11 viewed from the side opposite to that of FIG. 11.

In operation, the rotation of the cylinder following the first angular stroke of rotation of the cylinder has the effect, on the one hand, to disengage the rod bolt of the drive rod and, secondly, to disengage the rod 110 cylinder which is engaged with the fixed member 140 of the lock assembly of Fig. 13 (support 140).

More particularly, the disengagement of the rod rod is carried out as follows: the pinion gear 1 00 rotates (according to the arrow in FIG 11) and the peripheral shape of the pinion plays the role of a cam which cooperates with the upper edge 118a of the movable piece 118 (Figs 11 and 12) to lower said piece (by fighting against the elastic force of the resilient means 120). In lowering, the pin 130 (Figs 11 and 12) slides in the groove 132 (Fig.13).

As shown in Figure 13, the pin 132 is then disposed in the axis of the light 142 and is free to slide there. The rod 110 is thus disengaged from the fixed element 140 when the moving part 118 is in its second position in which it no longer cooperates with the fixed element 140.

By continuing the rotation of the cylinder in a second angular rotation of the cylinder the bonnet of the pinion 100 can mesh with the teeth 116 to the extent that the piece 118 (unlocking groove of the rod cylinder) has cleared. Panets thus intermeshed and the cylinder rotating, the rod cylinder 110 is driven in axial translation. The pin 130 slides in the light 142.

As the rod 110 carries the drive pin 122 and that it is disposed opposite a shoulder of the bolt rods 20 and half-turn 22 (in Figure 14 only the rod bolt 20 is shown, the rod half -turn being concealed behind), the axial displacement of the rod cylinder 110 causes the axial displacement of the rods bolt and half-turn (in the same direction indicated by the vertical arrow in Figure 14).

Figure 15 illustrates in top view (view of the edge or edge of each rod) all parts and the finger 122 pushing the two rods 20, 22 at a stall / shoulder thereof.

Note that the rotation of the cylinder in the other direction of rotation causes the rod cylinder in the opposite direction of translation and raises the piece 118 in the position of Figure 11 (closing / locking of the lock assembly and therefore closing of the door).

The various components of the motor drive, follower for actuator and cylinder systems can vary in their structure and in their arrangement with respect to each other. It is the same for the different mechanisms of disengagement of the rod bolt / rod motor and the rod cylinder.
