Description

The present invention relates to a device for locking and unlocking an opening which comprises a closing system of the door, window or the like type.

This invention relates to the field of the building and, more particularly, that of the hardware intended to equip a closure system designed to close an opening that includes a construction.

In fact, such a closure system comprises, usually, a fixed frame, intended to be secured to the masonry of the building, and at least one opening mounted in displacement relative to such a frame.

The present invention will find a particularly suitable application (but however not limiting) for a closure system comprising at least one opening slidably mounted relative to the frame, or even compared to another opening.

Such a closure system comprises a locking and unlocking device, associated with an opening or the frame of this system, and designed to ensure the locking and unlocking of such an opening relative to said frame.

Such a locking / unlocking device comprises a housing equipping the opening or the frame, a follower rotatably mounted relative to this housing, and a rod mounted in translation relative to this housing. Said rod is driven in translation by the follower and comprises at least one locking member designed to cooperate with a striker that includes the frame or the opening.

In this respect, it will be observed that such a locking / unlocking device is actuated by means of an operating member. In fact and according to the type of closure system considered, such an operating member may adopt different forms (in particular, a handle, a crutch, a lever ...) and present different kinematics (rotation, translation ...) but also adopt different positions (angular or linear) and / or have different travel distances. In particular, for a window called "sliding pocket", the actuating member can adopt a rotational movement whose stroke can be 180 ° while for a conventional sliding window, the actuating member can adopt a movement of rotation whose stroke can be 90 ° or less.

Thus, for the same locking / unlocking device, the stroke may be different depending on the intended application. This results in a wide variety of locking / unlocking devices and, therefore, extended ranges of these devices for functions that may be similar.

The document GB-2,237,601 discloses a locking and unlocking device having the features of the preamble of claim 1. However, this device has a number of disadvantages. In particular, this device comprises a follower whose travel is limited substantially to 90 ° which does not allow to consider the use of such a device for a closure system whose actuator has a greater than 90 °, in particular a run of 180 °.

The present invention aims to overcome the disadvantages of locking / unlocking devices of the state of the art.

In addition, the object of the present invention is to propose a rationalization of the ranges of these locking / unlocking devices by introducing into the operating chain a specific transmission means capable of compensating for certain variables related to the installation environment, in particular the positions start and end of the race as well as the overall race. Thus, different actuators can be used with a single compatible locking / unlocking device.

• un boîtier destiné à équiper ledit ouvrant ou un cadre dormant que comporte le système de fermeture ;
• un fouillot, monté en rotation par rapport audit boîtier selon un axe de rotation ainsi que selon une course de rotation déterminée, et comportant des moyens d'entraînement ainsi que des moyens de réception pour recevoir un organe de manoeuvre ;
• une tringle de verrouillage, d'une part, montée en translation par rapport audit boîtier selon une direction et selon une course de translation déterminées ainsi qu'entre une position de verrouillage et une position de déverrouillage, et, d'autre part, comportant des moyens d'entraînement complémentaires coopérant avec les moyens d'entraînement du fouillot, ceci pour un entraînement de ladite tringle par ledit fouillot ;
• les moyens d'entraînement et les moyens d'entraînement complémentaires qui sont conformés pour adopter, d'une part, une position active de coopération sur une partie seulement de la course de rotation du fouillot et, d'autre part, une position inactive de coopération sur au moins une autre partie de la course de rotation du fouillot ;
• des moyens d'opposition pour s'opposer au déplacement en translation de la tringle par rapport au boîtier, ceci en position inactive de coopération entre les moyens d'entraînement et les moyens d'entraînement complémentaires.

To this end, the invention relates to a device for locking and unlocking an opening which comprises a closing system of the door, window or the like type. This device comprises:

• a housing intended to equip said opening or a fixed frame that includes the closure system;
• a follower, rotatably mounted relative to said housing along an axis of rotation as well as according to a determined rotational stroke, and comprising drive means as well as receiving means for receiving an operating member;
• a locking rod, on the one hand, mounted in translation relative to said housing in a determined direction and in a translation travel as well as between a locking position and an unlocking position, and, on the other hand, comprising complementary drive means cooperating with the driving means of the follower, this for a drive of said rod by said follower;
• the drive means and the complementary drive means which are shaped to adopt, on the one hand, an active position of cooperation on only a part of the fool's rotation path and, on the other hand, an inactive position of cooperating on at least one other part of the fool's rotation stroke;
• opposition means for opposing the displacement in translation of the rod relative to the housing, this in the inactive position of cooperation between the drive means and the complementary drive means.

In fact, this locking and unlocking device is characterized in that the opposing means comprise, on the one hand, two stops that includes the rod and, on the other hand, two bodies, that includes the follower, which are each designed to cooperate with one of these stops in the inactive position of cooperation between the drive means and the complementary drive means, and which are staggered axially and angularly along the axis of rotation X of the follower.

Another characteristic is that the drive means and the complementary drive means are shaped to adopt at least one inactive position of cooperation beyond the execution of a given rotation stroke of the follower.

Yet another feature is that, on the one hand, the stops of the opposing means are constituted, each by a border that comprises a housing that comprises the complementary drive means and, on the other hand, the organs these means of opposition are each constituted by a disk portion, which comprises the follower, which extends in a plane perpendicular to the axis of rotation X of the follower and at least inside the housing complementary drive means.

An additional feature relates to the fact that the rod comprises two long-shaped orifices extending in the direction Y of translational movement of the rod and parallel to one another, while the opposition means comprise both organs, one of which extends inside one of the longiform orifices while the other extends inside the other longiform orifice.

Yet another feature is that the abutments and / or the organs and / or the longiform orifices are offset laterally relative to each other and / or longitudinally with respect to the Y direction of movement of the rod.

An additional feature relates to the fact that the device comprises limiting means for limiting the angular travel of the follower, these limiting means being, in particular removable or retractable type.

According to another characteristic, the receiving means of an operating member are designed to receive such an operating member in a plurality of positions angularly offset, this along the axis of rotation of the follower.

• le dispositif de verrouillage et de déverrouillage présente les caractéristiques décrites ci-dessus ;
• l'axe de rotation du fouillot de ce dispositif de verrouillage et de déverrouillage est perpendiculaire au plan, selon le cas, de l'ouvrant ou du cadre dormant ;
• la direction de translation de la tringle de verrouillage est parallèle au plan, selon le cas, de l'ouvrant ou du cadre dormant.

The invention also relates to a closing system of the door, window or the like type, this closure system comprising a fixed frame extending in a plane, an opening extending in a plane, a locking and unlocking device. said opening, this locking and unlocking device equipping, as the case, said opening or said frame. This closure system is characterized by the fact that:

• the locking and unlocking device has the characteristics described above;
• the axis of rotation of the follower of this locking and unlocking device is perpendicular to the plane, as appropriate, the opening or the fixed frame;
• the direction of translation of the locking rod is parallel to the plane, as appropriate, the opening or the frame.

Thus, the locking / unlocking device according to the invention comprises drive means and complementary drive means shaped to adopt, on the one hand, an active position of cooperation on only part of the fool's rotation path. and, on the other hand, an inactive position of cooperation on at least one other part of the foolish rotation path.

This characteristic then allows the follower to present, on the one hand, a stroke during which the follower drives the rod and, secondly, a vacuum stroke during which the follower, although rotatable, does not lead not the rod which, then, remains motionless and does not move.

The presence of this vacuum stroke allows, then advantageously, this follower to ensure a discontinuous transmission of a control maneuver exerted by an actuator engaged with the follower. This actuator (and, therefore, the follower it drives) is then likely to adopt a vacuum stroke relative to the rod, more particularly when the rod adopts a locking position and / or unlocking.

In particular, in the case of an operating member operating at 180 ° and comprises a closing system whose sliding leaves intersect, the locking / unlocking device according to the invention requires the user to exceed 90 ° of stroke to obtain the locking / unlocking of the locking points and, consequently, encourages the user to complete the entire 180 ° stroke, for example necessary to store a maneuvering member in the form of a lever in a handle -coquille that includes this closure system.

Another feature is that the device comprises opposition means to oppose the translational movement of the rod relative to the housing, this in the inactive position of cooperation between the drive means and the complementary drive means . These opposition means advantageously make it possible to prevent the rod from moving, particularly under the effect of an action (for example of a break-in) exerted on this rod or on a locking member associated with this rod, this in the inactive position of cooperation between the drive means and the complementary drive means, therefore in the absence of drive control of this rod by the follower and / or outside (more particularly beyond) a race of the follower on which it drives the rod and / or for a position of the follower corresponding to the idle stroke of this follower, in particular beyond (especially on both sides) of the race of the nut on which this one drives the rod. In particular, these opposing means make it possible to prevent, in the locking or unlocking position of the device, an actuation (unlocking or unlocking) of the rod or the locking member.

The presence of this vacuum stroke also makes it possible to compensate for certain variables related to the installation environment, in particular the starting, end of travel, locking and unlocking positions as well as the overall race.

This also makes it possible to use a locking / unlocking device according to the invention both for a closure system comprising an operating member requiring a rotational stroke of 90 ° and for a closure system comprising an operating member. requiring a rotation stroke of 180 °.

This vacuum stroke allows, again, to use different actuators with the same locking / unlocking device compatible and / or different closure system.

The present invention then makes it possible, advantageously, to rationalize the ranges of the locking / unlocking devices.

Another advantage is that the locking / unlocking device can very easily be made interchangeable with existing closure systems, since the elements object of the invention, such as, for example, a square-shaped follower and its connecting rod. transmission, are widely standardized elements in the chain of transmission between actuators and locking systems.

Finally, the locking / unlocking device according to the invention comprises, as the devices of the state of the art, elements (receiving means of a maneuvering member, rod) which are widely standardized in the transmission chain between the actuating member and the locking members. This advantageously makes it possible to substitute a locking / unlocking device according to the invention for a device of the state of the art.

Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

• the figure 2 is a schematic perspective view, in detail of the follower and the rod that comprises the device according to the invention;

• the Figures 4a to 4c are schematic and perspective views of the device according to the invention, this in different positions of the follower and the rod.

The present invention relates to the field of the building and, more particularly, that of the hardware intended to equip a closure system, constituted by a door, a window or the like, and designed to close an opening that includes a construction.

In this regard, it will be observed that such a closure system comprises, usually, firstly, a dormant frame intended to be secured to the masonry of the construction and extending in a usually vertical plane, and, d ' on the other hand, at least one opening, mounted in displacement relative to such a frame, and extending in a plane usually vertical and at least parallel to the plane in which extends the frame. In fact, the present invention will find a particularly suitable application (but however not limiting) in the case of a closure system comprising a plurality of openings, at least one of which is slidably mounted relative to the frame and compared to another opening.

Additionally, such a closure system comprises a locking and unlocking device 1, associated with an opening or the fixed frame of this closure system, and designed to ensure the locking and unlocking of such an opening relative to said sleeping frame.

For reasons of simplification, in the remainder of the description, reference will more particularly be made to a configuration in which such a locking and unlocking device 1 is associated with an opening of the closure system knowing that the invention is in no way limited to this configuration and also relates to an alternative configuration in which such a locking device and unlocking 1 is associated with the fixed frame of such a closure system.

The invention relates, then, more particularly, such a device 1 for locking and unlocking.

Such a locking and unlocking device 1 comprises a housing 2 intended to equip the opening (or the frame according to the abovementioned alternative configuration) that includes the closure system.

In fact, this housing 2 is, more particularly, engaged (even and preferably immobilized) within a reservation that includes such an opening (or that includes the frame according to the abovementioned abovementioned configuration), more particularly in rebate of this opening (or of this sleeping frame).

Said locking and unlocking device 1 also comprises a follower 3, rotatably mounted relative to said housing 2 (more particularly at least partly inside this housing 2), this along an axis of rotation X as well as according to a race (more particularly angular) of rotation determined.

In this regard, it will be observed that said follower 3 is rotatably mounted between two extreme (angular) positions, delimiting the determined rotational stroke of this follower 3, and substantially corresponding to the locking and unlocking positions of the device 1.

Another characteristic of this follower 3 consists in that it comprises drive means 30.

As can be seen in the appended figures, these drive means 30 may take the form of at least one tooth 300 or the like extending radially with respect to the axis of rotation X.

Yet another feature of this follower 3 consists in that it comprises receiving means 31 for receiving an actuator (not shown) that includes the closure system.

More particularly, these receiving means 31 are designed to receive a maneuvering square that includes such a maneuvering member which further comprises a gripping means including a handle, a crutch, a lever or other.

In this regard, it will be observed that such receiving means 31 may be designed to receive such a maneuvering square (and, consequently, such an actuator) in a plurality of positions angularly offset by a given angle, this according to the axis of rotation X of the follower 3.

The locking and unlocking device 1 also comprises a locking rod 4 comprising at least one locking member (designed to cooperate with a latch that includes the frame or the opening) or cooperating with a transmission means comprising a such locking member, this for locking the opening relative to the frame.

Such a locking rod 4 is mounted in translation relative to said housing 2, in a direction Y and in a determined travel path and between a locking position and an unlocking position.

The Y direction of translation of the locking rod 4 is substantially perpendicular to the axis of rotation Y of the follower 3.

This locking rod 4 comprises complementary drive means 40 cooperating with the drive means 30 that includes the follower 3, this for a drive of said rod 4 by said follower 3, more particularly under the influence of the organ mentioned above and between the locking position and the unlocking position.

As can be seen in the appended figures, these complementary drive means 40 may take the form of at least one housing 400 that comprises said locking rod 4. In fact, such a housing 400 is preferably a through-type and is constituted by a cutout that comprises the locking rod 4.

According to the invention, the drive means 30 and the complementary drive means 40 are shaped to adopt, on the one hand, an active position of cooperation on only a part of the rotation path of the follower 3 and, of on the other hand, an inactive cooperation position on at least one other part of the fool's rotation path 3.

In fact, these drive means 30 and these complementary drive means 40 are shaped to adopt an active position of cooperation in which the follower 3 drives the locking rod 4 in translation, this between the locking position and the position of unlocking adopted by this rod 4.

These drive means 30 and these complementary drive means 40 are then also shaped to adopt an inactive position of cooperation in which the follower 3, despite its rotation, does not cause the rod 4 in translation. In fact, this inactive position of cooperation is adopted, more particularly, after the rod 4 has been brought into the locking or unlocking position by the follower 3.

As mentioned above, these drive means 30 and these complementary drive means 40 are shaped to adopt an inactive position of cooperation on at least one other part of the rotation stroke of the follower 3. In this regard, observe that these means (30; 40) are preferably shaped to adopt such an inactive position of cooperation on two parts of the rotational stroke of the follower 3 other than the part on which the drive means 30 and the drive means complementary training 40 adopt an active position of cooperation. In fact, these two other parts are located on either side of this part of the race of the follower 3 on which the drive means 30 and the complementary drive means 40 adopt an active position of cooperation.

According to a preferred embodiment, these means (30; 40) adopt an inactive position of cooperation, on the one hand, on a first part of the rotational path of the follower 3 corresponding to a position in which the rod 4 adopts a position locking and movement of this nut 3 towards the locking position of the device 1 and, secondly, on a second part of the rotational stroke of the follower 3 corresponding to a position in which the rod 4 adopts a unlocking position and a movement of this follower 3 towards the unlocking position of the device 1.

Anyway and as mentioned above, these drive means 30 and these complementary drive means 40 are shaped to adopt an inactive position of cooperation on at least a part of the fool's rotation path 3 other than the part on which the drive means 30 and the complementary drive means 40 adopt an active position of cooperation.

Thus and according to an additional characteristic, these drive means 30 and these complementary drive means 40 are shaped to adopt at least one inactive position of cooperation beyond the execution of a given rotational stroke of the follower 3.

In this regard, it will be observed that this given rotational stroke of the follower 3 corresponds, more particularly, to the rotational stroke, on the one hand, on which the drive means 30 and the complementary drive means 40 adopt a position active cooperation and, secondly, necessary to drive the rod 4 in translation between the locking or unlocking positions.

Anyway, in the inactive position of cooperation between the training means 30 and the means 40, the follower 3 has a vacuum stroke, this with respect to the rod 4.

In fact, said follower 3 has at least one idle stroke, this between the extreme positions of this follower 3 corresponding, more particularly, to the locking and unlocking positions of the operating member and the device 1 itself.

In this regard, it will be observed that, between these extreme positions, this follower 3 has, more particularly, two vacuum strokes, each of which preferably covers an angular sector smaller than 90 °. Such an embodiment advantageously makes it possible to guarantee that the user of the locking and unlocking device 1 will perform the complete travel of the operating member if he wishes to obtain the complete locking or unlocking of the device 1 whose positions are generally spaced by an angle multiple of 90 °.

Another feature of the device 1 according to the invention consists in that it comprises opposition means (5; 5 ') for opposing the translational movement of the rod 4 relative to the housing 2, this in position inactive cooperation between the drive means 30 and the complementary drive means 40.

In this regard, it will be observed that these opposition means (5; 5 ') are designed to brake or (and preferably) immobilize the bead wire 4 relative to the housing 2.

Since these opposition means (5; 5 ') are designed to oppose the movement of the rod 4 in the inactive cooperation position, these opposition means (5; 5') oppose such displacement. of the rod 4 in the absence of control of the rod 4 by the follower 3 (and, therefore, in the absence of control of this rod 4 by the operating member through the follower 3) and / or then this rod 4 adopts a locking position or unlocking.

In fact, these opposing means 5 oppose the movement of the bead wire 4 beyond the determined travel of the follower 3.

As can be seen in the appended figures, these opposing means (5; 5 ') comprise, on the one hand, at least one abutment (50; 50') that comprises the bead wire 4 and, on the other hand, least one member (51; 51 '), which comprises the follower 3, and which is designed to cooperate with such a stop (50; 50'), this in the inactive position of cooperation between the drive means 30 and the drive means complementary training 40.

Such a member (51; 51 ') constitutes, then, and depending on the case, a brake or (and preferably) a stop.

As mentioned above, the drive means 30 adopt the shape of at least one tooth 300 while the complementary drive means 40 comprise and / or adopt the shape of at least one housing 400. , more particularly, within such a housing 400 that engages such a tooth 300 and with a border of such a housing 400 that cooperates with such tooth 600 for driving the rod 4.

Also and according to another characteristic, the abutment (s) (50; 50 ') of the opposing means (5) consist of a border that includes such a housing (400) while the one or more members (51; 51') consist of a disk portion (510; 510 '), which comprises the follower 3, which extends in a plane perpendicular to the axis of rotation X of the follower and at least within such a housing 400.

As mentioned above, such a housing 400 is of the through type so that the device 1 can be designed such that such a member (51; 51 ') passes through such a housing 400.

Another characteristic illustrated in the appended figures is that such a member (51; 51 ') extends from a tooth 300 of the drive means 300 and / or that the tooth 300 of these means drive 30 is constituted by an end of such a member (51; 51 ').

Another characteristic consists in that the bead wire 4 comprises at least one longiform orifice (6; 6 '), extending in the direction Y of displacement in translation of the rod 4, and within which extends such a member (51; 51 ') of the opposition means 5.

According to a first embodiment, such an orifice (6; 6 ') can be of the blind type.

However, according to a preferred embodiment of the invention, such an orifice (6; 6 ') is of the through type (in particular in the form of a light, a cutout or the like) and is traversed by said member (51 51 ').

According to a preferred embodiment, such an orifice (6; 6 ') extends from the housing 400 of the complementary drive means 40 and / or such a housing 400 constitutes a part (in particular end) of a such orifice (6; 6 ').

In fact and according to a particular embodiment not shown, the opposing means 5 may comprise a single stop 50 and a single member 51 as described above. Such an embodiment corresponds, more particularly, to opposition means 5 designed to oppose the movement of the rod 4 when it adopts an unlocking position or (and preferably) a locking position.

However, according to a preferred embodiment of the invention illustrated in the appended figures, the opposing means (5; 5 ') comprise, firstly, two stops (50; 50') that includes the rod 4 and, on the other hand, two members (51; 51 '), which comprises the follower 3, and which are designed, each (51; 51'), to cooperate with one of these stops (50; 50 '), this in the inactive position of cooperation between the drive means 30 and the complementary drive means 40.

In this regard, it will be observed that these opposition means (5; 5 ') comprise, then, on the one hand, a first member 51 which cooperates with a first stop 50, this in the locking position of the rod 4 ( figure 4a ) and, secondly, a second member 51 'which cooperates with a second stop 50', in the unlocked position of the rod 4 ( figure 4c ).

In fact, said stops (50; 50 ') are each formed by a border which comprises the housing 400 which comprises the complementary drive means 40 while the members (51; 51') are each constituted by a portion of disc (510; 510 '), which comprises the follower (3), and which extends in a plane perpendicular to the axis of rotation X of the follower 3 as well as at least inside the housing 400 of complementary training means 4.

Such a border may be constituted by the edge of the housing 400 with which the drive means 30 (more particularly the tooth 300) cooperate for driving the rod 4.

Another characteristic consists in that the members (51; 51 ') of the opposition means 5 are offset axially and angularly along the axis of rotation X of the follower 3.

Yet another feature is that these members (51; 51 ') extend, on the one hand, on either side of the drive means 30 which the follower 3 comprises and on the other hand, to from these drive means 30.

More particularly, these members (51; 51 ') extend from these drive means 30, in the opposite direction, one with respect to the other 51', in particular in the direction Y of translation of the locking rod 4.

As can be seen in the appended figures, the stops (50; 50 ') and / or the members (51; 51') are offset laterally one (50; 51) relative to the other (50; 51 ') and / or longitudinally with respect to the Y direction of movement of the bead wire 4.

In fact and as visible in the appended figures, the drive means 30 may then be constituted by an end portion of these members (51; 51 ').

In this preferred embodiment, the bead wire 4 comprises two longiform orifices (6; 6 ') extending in the direction Y of translational movement of the bead wire 4, or even (and preferably) in the opposite direction. report to the other 6 '. The opposing means (5; 5 ') comprise two members (51; 51 ') of which one 51 extends inside one of these longiform orifices (6; 6') while the other 51 'extends inside the other longiform orifice 6 '.

In fact, these two longiform orifices (6; 6 ') extending parallel to one another 6 relative to the other 6'.

As can be seen in the appended figures, these longiform orifices (6; 6 ') are offset laterally one with respect to the other 6' and / or longitudinally with respect to the direction Y of displacement of the bead wire 4.

In addition, these two longiform orifices (6; 6 ') may lie in the extension of one 6 of the other 6'.

In fact and preferably, these two longiform orifices (6; 6 ') extend from the housing 400 of the complementary drive means 40, this in the opposite direction 6 with respect to the other 6'.

In this case, these two longiform orifices (6; 6 ') communicate with each other, this through the housing 400 of complementary drive means 40 which is, more particularly, constituted by a portion (in particular end) of these orifices (6; 6 ').

In an alternative or (and preferably) additional manner, said stops (50; 50 ') of the opposing means (5; 5') may each be constituted by a border that comprises such a longiform orifice (6; ), more particularly an edge opposite the edge of the housing 400 with which the drive means 30 (more particularly the tooth 300) cooperate for driving the rod 4.

Another feature is that the locking and unlocking device 1 comprises limiting means 7 for limiting the angular travel of the follower 3.

In fact, these limiting means 7 are, more particularly, designed to limit the angular travel of the follower 3 to 90 °.

According to another characteristic, such limiting means 7 may be of removable or retractable type.

The presence of these limiting means 7 then advantageously makes it possible to choose the angular travel of the follower 3 more particularly as a function of the type of maneuver corresponding to the actuating member envisaged for the locking and unlocking device 1. In particular, this makes it possible to choose an angular stroke of the follower 3 corresponding to an operation of this operating member in a stroke, as the case may be, of 90 ° (while retaining said limiting means 7), of 180 ° (by withdrawing or retracting these limitation means 7) or other.

Such removable or retractable limiting means 7 make it possible, also and advantageously, to limit, temporarily, the travel of the follower 3, more particularly between the manufacture of the device 1 and its mounting on a closure system, in particular between its manufacture and its preparation for its assembly, such a preparation being made according to the nature of the closing system and / or the implementation of the device 1. These limiting means 7 allow, therefore, to choose such a race (and, therefore, the type of maneuver as described above), this before and after the installation of the opening on the frame to be equipped.

Anyway and according to an additional feature, said limiting means 7 comprise, on the one hand, at least one relief 70 that includes the follower 3 and, on the other hand, at least one stop 71 that includes said housing 2, more particularly that comprises a part 20 that includes said housing 2.

As can be seen in the appended figures, such a part 20 covers at least a portion of said follower 3 which is positioned at least partly inside this part 20 and which is, more particularly, rotatably mounted to the inside this room 20.

As mentioned above, the limiting means 7 are of removable or retractable type.

Also and according to a first embodiment, the piece 20 comprises the stop or stops 71 mentioned above and can be defined of the removable type thus conferring on the abutment 71 or on the stops 71 of this piece 20 and therefore on the means of limitation 7, their removable nature.

However, according to another embodiment, the abutment (s) 71 themselves may be of removable type, respectively retractable, conferring on said limitation means 7 their removable or retractable character.

In particular, such a stop 71 may be constituted by a breakable pin.

A particular embodiment consists in that the relief or reliefs 70 of these limiting means 7 may consist of a tooth 300 of the drive means 30.

The invention also relates to a closure system which, as described above, comprises, on the one hand, a fixed frame intended to be secured to the masonry of the construction and extending in a generally vertical plane , and, secondly, at least one opening, mounted in displacement relative to such a fixed frame, and extending in a plane usually vertical and at least parallel to the plane in which extends the frame.

The closure system according to the invention also comprises a locking and unlocking device 1 having the characteristics described above and equipping, as the case, the opening or the fixed frame of this closure system.

In fact, in this closure system, the axis of rotation X of the follower 3 of the locking and unlocking device 1 is perpendicular to the plane, as the case may be, of the opening leaf or the frame

In addition, in this closure system, the Y direction of translation of the locking rod 4 is parallel to the plane, as appropriate, of the opening or the frame.

Another feature is that the housing 2 of the locking and unlocking device 1 extends substantially in a plane which, again, is parallel to the plane, as the case may be, of the sash or the fixed frame.

In this regard, it will be observed that the axis of rotation X of the follower 3 of the locking and unlocking device 1 is, then, perpendicular to the plane of the housing 2 while the Y direction of translation of the locking rod 4 is parallel to this plane of the housing 2.
