Description

The present invention relates to a device for limiting the folding of the apron of a closure system, at the end of the folding race of this apron. The invention also relates to a closing system apron comprising a final blade and such a limiting device. Finally, the invention relates to a closing system of an opening of a construction and comprising such an apron.

The present invention relates to the field of the building and, more particularly, that of the manufacture of systems designed to ensure the closure of an opening defined at a construction. In fact, such a closure system can be constituted by a shutter, a mosquito net, a blind, a garage door or other. This invention relates, more particularly, to a closure system incorporating a device for limiting the folding of the apron that includes such a closure system.

Such closure systems are known from now on.

In particular, the document EP-0092122 discloses a closure system comprising an apron and lateral slides within which slide the lateral ends of this apron. This closure system comprises, again, a device for limiting the folding of the apron.

This limiting device comprises, inside at least one slide, a support means for interrupting the folding of the apron. This limitation device comprises, again, a support engaged inside a lateral end of a blade of the apron of the closure system and a movable member rotatably mounted relative to said support. The end of this movable element is provided with a retractable abutment capable of occupying, by rotation of said movable element, an active position in which this abutment retractable can cooperate with the support means to interrupt the folding of the apron at the end of the apron folding stroke, an inactive position in which the retractable stop is cleared with respect to this support means and thus allows the continuation of the folding the apron beyond the end position, this in order to more easily remove the apron blocked high abutment in the event of a failure of the drive motor of a shaft which is associated with said apron. Finally, this limitation device also comprises a means for locking the retractable stop in its active position.

In fact, this locking means is constituted by a removable pin designed to cooperate with a plurality of holes in the movable member. Thus, to ensure the locking of the movable element, this pin cooperates with a first piercing of the movable element. When it comes to unlock the retractable stop, the pin is removed from the first hole to engage in a second hole (perpendicular to the first hole) before acting on the pin to rotate the movable member. Access to this second bore and the rotational drive of the movable member are permitted due to the presence of a notch in the final plate of the deck.

The limitation device described in this document EP-0092122 presents, however, a plurality of disadvantages.

Thus, according to a first drawback, this device comprises a pin which constitutes an additional element to the closure system and which is therefore added to the many parts that include such a system. In addition, this pin is an essential element for both locking and unlocking the retractable stop so that in the absence of this pin it is impossible to lock or unlock the stop. In addition, this pin is removable type so that during manufacture, installation, manipulation or intervention on the closure system, this pin is likely to to escape from its piercing or to be voluntarily removed from this piercing with a significant risk of losing this pin resulting in the disadvantages mentioned above.

It will also be observed that, at each interruption of the folding of the deck, the movable element alone suffers the constraints of this interruption of folding. The presence of a plurality of holes for the reception of a pin has the effect of weakening this movable element which, under the effect of these constraints, can be damaged or even broken, resulting in the blocking of the retractable abutment in its active position and the impossibility of manipulating this stop to bring it to its inactive position.

Finally, to allow rotation of the movable member by the pin, the final blade of the apron has a slot whose presence has the effect of weakening the final blade and reduce its resistance to a stress exerted on it either by wind or as part of an attempted break-in.

In the patent application EP-0242317 a device for limiting the folding of the apron of a closure system is described. This device comprises a support made integral with a deck blade and an element movable relative to this support, and secured to a final blade of this deck. This device also comprises a retractable abutment, which comprises the movable element, and which can occupy, on the one hand, an active locking position in which this abutment cooperates with a support means to interrupt the folding of the apron and on the other hand, an inactive blocking position in which this stop is erased relative to this support means to allow the folding of the apron. This device also comprises a means for mounting the movable element sliding relative to the support and a means for mounting the retractable stop in displacement relative to the movable element, this between the active position of blocking and inactive blocking position.

In fact, the device described in the document EP-0242317 is designed to prevent the folding of the apron of a closure system, this when the apron adopts a fully deployed position and in the case of an attempted burglary consisting in exerting, under the final blade of the deck, a pressure towards the high, more particularly by levering on this final blade. Consequently, this device constitutes an anti-lifting device of the apron which, in the context of a normal folding / unfolding maneuver of this apron, comprises a retractable stop adopting an inactive position of blocking thus making it possible, in no way, to limit the folding of the apron at the end of the folding race of this apron. In addition, at the end of the apron folding stroke and after stopping the apron folding operation, a pressure exerted upwards and on the final blade brings the retractable stopper into an active locking position preventing, then, the continued folding of the deck beyond the end position (especially inside a box) and thus making it much more difficult dismantling the apron blocked high abutment, this in the case of a maintenance or repair operation of the closure system.

We know, also and by the document EP-2014864 , a rolling shutter type closure system intended to equip an opening defined at the level of a construction.

This system comprises an apron comprising a final blade, lateral slides inside which move the lateral ends of the apron, and a device for limiting the folding of the apron at the end of the apron folding stroke. This device comprises a support provided with means for receiving the final blade of the deck and a movable element relative to this support. This device also comprises a retractable abutment which, at the end of the folding stroke of the apron, can occupy, on the one hand, and in the absence of intervention on the limitation device, an active locking position in which this abutment cooperates with a
support means that comprises at least one of the slides, this to interrupt the folding of the deck, and, on the other hand and under the effect of an intervention on the limiting device, an inactive blocking position in which this stop is erased with respect to this support means, this to allow the continuation of the folding of the apron beyond the end position. This device also comprises means for locking the retractable stop in the active blocking position. This device also comprises a means for mounting the movable element sliding relative to the support and a means for mounting the retractable stop in displacement relative to the movable element, this between the active position of blocking and inactive blocking position.

The object of the present invention is to overcome the drawbacks of limitation devices of the state of the art.

  • un support pourvu d'un moyen pour la réception de la lame finale du tablier;
  • un élément mobile par rapport à ce support ;
  • une butée escamotable qui, en fin de course de repliement du tablier, peut occuper, d'une part et en l'absence d'intervention sur le dispositif de limitation, une position active de blocage dans laquelle cette butée coopère avec un moyen d'appui que comportent l'ouverture et/ou l'une au moins
    des coulisses et/ou le caisson du système de fermeture, ceci pour interrompre le repliement du tablier, et, d'autre part et sous l'effet d'une intervention sur le dispositif de limitation, une position inactive de blocage dans laquelle cette butée est effacée par rapport à ce moyen d'appui, ceci pour autoriser la poursuite du repliement du tablier au-delà de la position de fin de course ;

  • un moyen pour le montage de l'élément mobile en coulissement par rapport au support ainsi qu'un moyen pour le montage de la butée escamotable en déplacement par rapport à l'élément mobile, ceci entre la position active de blocage et la position inactive de blocage.

To this end, the invention relates to a shutter type shutter, mosquito net, blind, garage door or other, intended to equip an opening defined at a construction, this system comprising:

• an apron with a final blade;
• lateral slides inside which move the lateral ends of the deck and / or at least one box inside which is wound and from which the deck is unwound;
• a device for limiting the folding of the apron at the end of the apron folding stroke, this device comprising:
  • a support provided with means for receiving the final blade of the apron;
  • an element movable relative to this support;
  • a retractable stop which, at the end of the folding stroke of the apron, can occupy, on the one hand and in the absence of intervention on the limitation device, an active locking position in which this stop cooperates with a means of support provided by the opening and / or at least one
    slides and / or the box of the closure system, this to interrupt the folding of the apron, and, secondly and under the effect of an intervention on the limiting device, an inactive blocking position in which this stop is erased relative to this support means, this to allow the continuation of the folding of the deck beyond the end position;
  • means for locking the retractable stop in the active locking position;
  • a means for mounting the movable member sliding relative to the support and a means for mounting the retractable stop moving relative to the movable member, this between the active locking position and the inactive position of blocking.

This closure system is characterized in that the movable element comprises the retractable stop while the locking means of the retractable stop is constituted by
the support which, by sliding of the movable element relative to the support, can occupy, on the one hand, a locking position of the retractable stop in the active locking position and, on the other hand, an unlocking position of this retractable stop.

The device for limiting the folding of the deck according to the invention comprises a means of locking the retractable stop constituted by the support that incorporates this device. Advantageously, this locking means is, therefore, an integral part of the device and in no way constitutes a removable part that can be lost or lost.

The limiting device according to the invention comprises a support, a movable element and a retractable stop. This device consequently comprises, and advantageously, a limited number of parts. In addition, these parts have a simple shape, easily achievable and reproducible, and requiring no additional intervention as a drilling operation for parts of the state of the art.

These parts are, therefore, in no way weakened by such additional intervention which allows these parts to maintain their integrity and ensure a high level of reliability.

Additionally, these parts are designed and arranged so as to be able to move relative to each other in accordance with simple movements (sliding, rotation) and in a simplified kinematics advantageously to make reliable the operation of this device.

Another advantage is that mounting the limiting device on the closure system simply involves engaging a portion of this device within the final blade. Such an assembly requires no modification of the deck of this closure system, including a modification that would lead to weaken this deck as is the case for devices of the state of the art. This apron retains, therefore advantageously, all its features, including its rigidity.

Another characteristic is that, during normal operations of folding / unfolding the deck as well as at the end of the apron folding stroke, the retractable stop adopts an active blocking position, this in the absence of particular intervention on the closure system and, in particular, in the absence of intervention on the apron or on the device for limiting the folding. This allows, at the end of the apron folding stroke and in the absence of such intervention, to limit the folding of the apron and, thus, prevent the complete engagement of this apron inside a box and / or the release of this apron out of the guide slides.

Yet another characteristic is that, at the end of the apron folding stroke, the retractable stop can adopt an inactive blocking position, this under the effect of intervention (manual) on the closure system, in particular under the effect of an intervention on the limitation device, more particularly on the retractable stop. Also and under the effect of such an intervention, the retractable stop adopts an inactive position of blocking allowing the continuation of the folding of the deck beyond the end position, more particularly in order to push the deck completely to the end. inside a box and / or extract the apron out of its guide slides, especially in the context of a maintenance operation or repair of the closure system.

In addition and advantageously, during these normal operations of folding / unfolding the deck as well as at the end of the apron folding stroke, the retractable stop is locked in its active locking position which allows this retractable abutment always ensure a limitation of the folding of the apron at the end of the race of folding of this apron.

Unlocking the retractable stop is made simply by ensuring the sliding of the movable member relative to the support (or support relative to the movable member), more particularly by exerting pressure upwards and on this support. This sliding is, in fact, controlled by a simple intervention (manual) on the final telescopic blade of the deck and consisting of pushing the movable section of the final blade towards the fixed profile of the final blade.

This unlocking allows, then and at the end of the apron folding stroke, to make (manually) adopt the retractable stop an inactive blocking position.

Advantageously, the limiting device according to the invention can equip a closure system directly during its manufacture but also after, especially after implantation of this closure system at the construction.

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 present invention relates to the field of manufacturing systems 1 designed to ensure the closure of a defined opening at a construction.

In fact, such a closure system 1 may be constituted by a roller shutter, a mosquito net, a blind, a garage door or other. In the following description, it will be more particularly refers to a closure system 1 consisting of a shutter knowing that the present invention is in no way limited to this embodiment.

Whatever the case may be, whatever the closure system 1, it comprises an apron 2 incorporating at least one blade, or even constituted by an assembly (particularly longitudinally) of a plurality of blades.

In particular, such a deck 2 comprises a final strip 20 constituting a free end of this deck 2. This final deck 20 comprises, on the one hand, a fixed section 21 connected to an upstream part of the deck 2, on the other hand, a movable section 22 forming a distal end of this deck 2 and, secondly, a means 23 for mounting the movable section 22 in displacement relative to the fixed section 21.

In fact, such a mounting means 23 is designed to allow a sliding of these sections (21; 22) one (21; 22) relative to the other (22; 21), more particularly by engagement of a such profile (more particularly the movable section 22) partly inside the other section (more particularly the fixed section 21).

A preferred embodiment of the invention consists in that this mounting means 23 is of the telescopic type.

The closure system 1 also comprises lateral slides (3; 3 '), implanted on either side of the opening, and usually adopting a "U" section or the like. It is, more particularly, within these lateral slides (3; 3 ') that are engaged and scroll the lateral ends (24; 24') of the deck 2, more particularly the lateral ends of the blades of this deck 2 .

This closure system 1 comprises, again, an assembly, which the apron 2 is made integral, and designed to ensure the folding and deployment of the apron 2.

Such an assembly comprises at least one driving means of the deck 2 (in particular in the form of a motor), or even a means (for example in the form of a chain, a belt, a rod or analog) for connecting this drive means to said apron 2.

However, and according to a preferred embodiment, such an assembly may comprise a shaft, from which the deck 2 is made integral, on which is folded (more particularly by winding) and from which is deployed (more particularly by unwinding) this deck 2 .

This assembly comprises, then again, a means for driving said shaft in rotation, in order to ensure the folding or the deployment of the deck 2.

Such a drive means may be of the manual type or, preferably, of the motorized type (more particularly in the form of an electric motor).

As can be seen in the appended figures, the closure system 1 may also comprise a box 4, surmounting the lateral slides (3; 3 '), receiving internally the winding / unwinding shaft of the deck 2, and inside which is folded this apron 2.

According to an additional characteristic, this closure system 1 also comprises a device 5 for limiting the folding of the apron 2, this at the end of the folding of this deck 2.

As can be seen in the appended figures, this limiting device 5 comprises a support 6 provided with a means 60 for receiving the final blade 20 of the apron 2, more particularly for the reception of the mobile section 22 that comprises this final blade. 20.

In fact, this means 60 for receiving the final blade 20 is constituted by a tip, extending laterally relative to the support 6, and intended to be engaged (more particularly by interlocking) and immobilized (more particularly by clamping, in particular through a tight engagement, or by deformation of the profile) within a housing that includes this final blade 20 (more particularly that includes the movable section 22 of the final blade 20). In this regard, it will be observed that the tip is engaged within the housing of the final blade 20, this laterally with respect to this final blade 20. The support 6 equips, then, the final blade 20 (and, therefore, the apron 2) and extends laterally with respect to this final blade 20 (and, therefore, with respect to this apron 2), this in the plane in which this final blade 20 extends (and, therefore, this apron 2 ), especially in the deployed position of this apron 2.

This limiting device 5 further comprises an element 7 movable relative to the support 6. This movable element 7 comprises, on the one hand, two side and spaced walls (not shown) and two parallel longitudinal walls (70; 70 '). ) and spaced apart, defining between them (70; 70 ') an internal volume 71 to the movable element 7. On the other hand, this movable element 7 comprises a bottom 72, extending in a manner lateral (more particularly perpendicular) from a longitudinal wall 70 and towards the other longitudinal wall 70 ', and defining with this other longitudinal wall 70' an opening 73.

This movable element 7 may, again, comprise a means for receiving a final blade 20 (more particularly the fixed profile 21 that includes this final blade 20) that comprises the apron 2 of the closure system 1. Such a receiving means may again take the form of a tip, extending laterally relative to this movable member 7, and intended to be engaged (more particularly by interlocking) and immobilized (more particularly by clamping, in particular through a tight fitting, or by deformation of the profile) inside a housing that includes this fixed profile 21 of the final blade 20.

Alternatively (and as illustrated Figures 2 to 5 ), this movable element 7 may comprise a means 74 for receiving a piece 8 (more particularly in the form of a strip or the like) that comprises the closure system 1 and which is designed to control the orientation of the adjustable blades that comprises the apron 2 of the closing system 1. Such a receiving means can take the form of a housing inside which is engaged and immobilized a free end of said part 8.

In addition, the limiting device 5 comprises means for mounting this mobile element 7 in sliding relative to the support 6.

Such a sliding mounting means is constituted, on the one hand, by a housing 61, which comprises said support 6, and which receives, internally and in sliding, at least a part of the mobile element 7. As visible on the Figures 4 and 5 , this housing 61 has an opening 62 for the passage of the control part 8 mentioned above.

On the other hand, this sliding mounting means is constituted by a slider 75, which comprises said movable member 7 (at least partly constituted by such a slider 75), and which is slidably mounted inside the housing 61 of the support 6, this between a retracted position inside this housing 61 ( figure 2 and 4 ) and a deployed position outside the housing 61 ( figure 3 and 5 ).

As can be seen in the appended figures, it is, more particularly, at this slider 75 that at least the side walls, the parallel longitudinal walls (70; 70 '), the internal volume 71, the cooling means are defined. reception 74, or even the bottom 72 and the opening 73.

The limitation device 5 also comprises a retractable stop 9 which can occupy, on the one hand, and as visible figures 2 and 4 an active blocking position in which this stop 9 cooperates with a bearing means (not shown), consisting of a portion of at least one lateral slide (3; 3 ') or a part of the casing 4, or that comprises at least one such lateral slide (3; 3 ') or this box 4, or that comprises the opening of the construction (more particularly the masonry which defines this opening) or an element associated with this opening. Such cooperation is provided at the end of the folding race of the deck 2, this to interrupt the folding of the deck 2 (more particularly inside said housing 4).

In fact, the retractable stop 9 adopts this active locking position in the absence of intervention (direct or indirect) on the limitation device 5. In particular, this retractable stop 9 occupies this active locking position at the end of the race. folding of the apron 2 as well as in the normal operation of the apron 2 of the closure system 1, particularly during the folding / unfolding maneuvers of the deck 2.

On the other hand and as visible figures 3 and 5 this retractable stop 9 may occupy an inactive blocking position in which this stop 9 is erased relative to said support means. In particular, this retractable stop 9 can occupy such an inactive position blocking end of the folding stroke of the deck 2, this under the effect of intervention (More particularly manual, especially with the aid of a tool) on the limitation device 5, more particularly on the retractable stopper 9. The adoption of this inactive blocking position advantageously allows to allow the continuation of the folding apron 2 beyond the end position.

In fact, this retractable stop 9 adopts this inactive blocking position outside the normal operation of the deck 2 of the closure system 1, more particularly when it comes to carrying out an intervention on this system 1, particularly in the context of after sales service and / or in case of failure of the drive motor of the deck 2 as will be described below.

According to a first feature, this retractable stop 9 is designed to pass (more particularly by tilting) from the inactive blocking position to the active blocking position, this under the effect of gravity and / or under the effect of a return means (spring or the like) and / or under the action of an action (pressure, repulsion) exerted by the support 6 on this retractable stop 9. In fact, such action can be exerted by deployment of the final blade 20, more particularly of the movable section 22 of the final blade 20, this after intervention on the deck 2 (folding beyond its end of folding position) and when the apron 2 or the system is put back into operation This action is, more particularly, exerted under the effect of a downward force exerted on the support 6, more particularly via the mobile section 22 of the final blade 20 (in particular under the effect of a traction of extenant exerted on this movable section 22).

As can be seen in the appended figures, the retractable stop 9 takes the form of a jumper comprising an inner branch 90, an outer branch 91, and a connection member 92 of these two branches (internal 90, external 91). .

According to another feature, at least the outer branch 91 (or even the inner branch 90) extends from the connecting member 92 diverging.

The outer branch 91 has a length greater than the inner branch 90, more particularly to allow the tilting of this retractable stop 9 from the inactive position to the active position, this under the effect of gravity.

In addition, this external branch 91 comprises at least one free end (or even an extension of this free end towards the connecting member 92) shaped bevel to facilitate a support on a support means to interrupt the folding of the apron 2 and / or to allow the support 6 to slide relative to the retractable stop 9 in order to push the latter 9 towards its active position.

It will be observed that the connecting member 92 comprises a flat portion, which has a common edge with the inner leg 90, and which is designed to rest on the bottom 72 of the movable member 7, this in the active position of the retractable stop 9.

As can be seen in the appended figures, it is, more particularly, the mobile element 7 which comprises such a retractable stop 9.

Thus and at least in the active locking position of the retractable stop 9 ( figures 2 and 4 ), the inner branch 90 of this retractable stop 9 extends inside the movable member 7 (more particularly within its internal volume 71) while the outer branch 91 extends outside of this movable element 7. This retractable stop 9 (more particularly its connecting member 92) then passes through the opening 73 that this movable element 7 has.

According to another characteristic, the limitation device 5 comprises, again, a means for mounting the retractable stop 9 in displacement with respect to the movable element 7, this between the active blocking position and the inactive blocking position of this retractable stop 9.

According to the invention, this means for mounting the retractable abutment 9 in displacement relative to the movable element 7 is constituted by a means for mounting this retractable abutment 9 in rotation relative to this movable element 7.

In fact, this rotational mounting means is designed to allow rotation of the retractable stop 9 about an axis perpendicular to the direction of sliding of the movable member 7 relative to the support 6. This axis is, then, also parallel to the longitudinal walls (70; 70 ') and perpendicular to the side walls of this movable element 7.

It will be observed that this rotational mounting means is designed to allow free rotation at an angle of between 20 and 40 °, preferably of the order of 30 °.

According to a preferred embodiment of the invention, the rotational mounting means of the retractable stop 9 relative to the movable member 7 is constituted by means for clipping the retractable stop 9 between the parallel side walls of the element. mobile 7.

In fact, the means for clipping comprise nipples equipping laterally the retractable stop 9 (or respectively the side walls), as well as housings, designed to cooperate with the nipples, and defined in correspondence in the side walls (respectively in the retractable stop 9).

Yet another feature of the invention consists in that the device 5 for limiting the folding has at least one means 10 for limiting the displacement, at least in rotation and / or in translation, of the retractable stop 9 relative to the moving element 7.

As can be seen in the appended figures, the means 10 for limiting the displacement in rotation of the retractable abutment 9 with respect to the mobile element 7 comprises at least one finger equipping a longitudinal wall 70 of the movable element 7, extending from this longitudinal wall 70 and in the direction of the retractable stop 9, and against which this retractable stop 9 comes to bear.

In fact, it is, more particularly, against this finger that comes to bear, or the inner branch 90 of the retractable stop 9 in the active locking position ( figures 2 and 4 ) of the retractable stop 9, the outer branch 91 in the inactive blocking position ( figures 3 and 5 ) of the retractable stop 9.

With regard to the means for limiting the movement in translation, this can be constituted, on the one hand, by at least one tongue equipping the connecting member 92 and extending from this connecting member 92 and towards the bottom 72 of the movable member 7 and, secondly, by at least one housing that comprises the bottom 72 of the movable member 7 and arranged corresponding to such a tab.

Finally, the limiting device 5 comprises means for locking the retractable stop 9 in the active blocking position.

In this regard, it will be observed that the means for locking the retractable stop 9 in the active locking position is designed to ensure such locking, this under the effect of gravity and / or under the effect of a means of return (spring or the like) and / or under the effect of a downward force exerted on the support 6, more particularly by means of the movable profile 22 that includes the final blade 20 (in particular under the effect of a traction downward exerted on this movable section 22).

This locking means advantageously makes it possible to lock the retractable stop 9 in the active blocking position, this at least during the folding operation of the deck 2 (in particular at the end of the folding stroke of the deck 2), or even during all the folding / unfolding maneuvers of this apron 2.

In fact, this locking means of the retractable stop 9 is constituted by the support 6 which, by sliding of the movable element 7 relative to the support 6 (or by sliding of the support 6 relative to the movable element 7), can occupy, on the one hand, a locking position of the retractable stop 9 in the active blocking position ( figures 2 and 4 ) and other part, an unlocking position of this retractable stop 9 ( figures 3 and 5 ).

It is, more particularly, in this unlocking position that this retractable stopper 9 is free in displacement (in rotation) with respect to the movable element 7 and is capable of being brought into an inactive position of blocking ( figures 3 and 5 ), more particularly under the effect of an intervention on the limitation device 5 (more particularly on the retractable stop 9), as mentioned above.

In this regard, it will be observed that this locking means (more particularly the support 6) is designed to allow such an unlocking, this under the effect of a pressure exerted upwards and on the support 6, more particularly by the intermediate of the movable section 22 that includes the final blade 20 (in particular under the effect of an upward pressure exerted on the movable section 22).

The invention relates, then, to a device 5, having the characteristics described above, and designed to ensure the limitation of the folding of the deck 2 of a closure system 1, this at the end of the folding of this deck 2.

This invention also relates to an apron 2 of closure system 1, more particularly of the shutter type, mosquito net, blind, garage door.

As mentioned above, this apron 2 comprises a final blade 20 comprising a fixed profile 21, a movable profile 22, and a means 23 for mounting the movable profile 22 in displacement (sliding) with respect to the fixed profile 21.

This apron 2 then also includes a device 5 for limiting the folding of this apron 2 having the characteristics described above.

In particular, this limiting device 5 comprises a support 6 provided with a means 60 for receiving the final blade 20 (more particularly the movable profile 22 of this final blade 20) of the apron 2.

In such a case and as described above, the means 60 for receiving the final blade 20 is constituted by a tip (extending laterally relative to the support 6, more particularly with respect to the housing 61 of this support 6 ) while this final blade 20 (more particularly its movable section 22) has a housing inside which said tip is engaged and immobilized.

With regard to the movable element 7, which comprises this device 5 for limiting the folding of the apron 2, the latter 7 is provided with a means 74 for receiving either the final blade 20 (more particularly the fixed profile 21 of this final blade 20) of the apron 2, that is to say a part 8 (more particularly in the form of an illustrated strip Figures 2 to 5 ) for controlling the orientation of adjustable blades that includes the apron 2, as mentioned above.

Regarding the means 23 for mounting the movable section 22 in displacement relative to the fixed profile 21, the latter 23 is designed to allow sliding of these profiles (21; 22) one (21; 22) by relationship to the other (22; 21).

This mounting means 23 is constituted by a sliding type mounting means and / or telescopic.

Finally, the present invention relates to a closure system 1 for equipping an opening defined at a construction. Such a closure system 1 may be constituted by a shutter, a mosquito net, a blind, a garage door or other.

• un tablier 2 ;
• des coulisses latérales (3 ; 3') à l'intérieur desquelles se déplacent les extrémités latérales (24 ; 24') du tablier 2 ;
• au moins un caisson à l'intérieur duquel est enroulé et à partir duquel est déroulé le tablier 2 ;
• un dispositif 5 de limitation du repliement du tablier 5 en fin de course de repliement du tablier 2.

This closure system 1 comprises:

• an apron 2;
• lateral slides (3; 3 ') within which the lateral ends (24; 24') of the apron 2 move;
• at least one box inside which is wound and from which the apron 2 is unwound;
• a device 5 for limiting the folding of the apron 5 at the end of the folding stroke of the apron 2.

According to the invention, the deck 2 has the characteristics described above. In particular, this apron 2 comprises the limiting device 5 having the characteristics mentioned above.

In addition, at least one of the slides (3; 3 ') and / or the box comprise at least one support means designed to cooperate with the retractable stop 9 in the active blocking position, this to interrupt the folding of the apron 2 at the end of the folding race of this apron 2.

Another feature is that at least a part of the limitation device 5 (more particularly at least the support 6, the movable member 7 and the retractable stop 9 that comprises the device 5) is positioned and moves to the inside a lateral slide (3; 3 ').

This invention will find a particular use when it comes to intervene on such a closure system 1 in case of failure of the drive means (more particularly motorized) of the winding shaft / unfolding of the deck 2, more particularly when this apron 2 is in the end of folding position.

In such a case, an operator exerts an action on the movable section 22 of the final blade 20 of repelling, by sliding, this movable section 22 in the direction and inside the fixed profile 21 of the final blade 20.

This action is constituted by a pressure exerted upwards and on the movable section 22.

By this action, the movable section 22 drives the support 6 of the limitation device 5 in sliding relative to the mobile element 7. This support 7 then passes from the locking position of the retractable stop 9 ( figures 2 and 4 ) to an unlocking position of this retractable stop ( figure 3 and 5 ).

Then, the operator causes a tilting of the retractable stop 9 (unlocked) from its active locking position to its inactive blocking position, this in particular by introducing a tool (for example a screwdriver) inside a lateral slide . This causes, then, the interruption of the cooperation between the retractable stop 9 and the support means, which releases the deck 2 whose folding is no longer limited.

It becomes, then, possible to push the deck 2 beyond its end position, especially inside the box. This allows the operator to easily dismount the deck 2 and access the defective body for repair or replacement.

After intervention on the defective member, the operator exerts traction on the deck 2 (in particular on the final strip 20, more particularly on the movable section 22) and / or actuates the drive means of this deck 2. The positioning of the retractable stop 9 in its active blocking position and the locking of this retractable stop 9 in its active locking position is done automatically (more particularly by gravity and / or by action on the final blade 20, in particular on the profile mobile 22 of this final blade 20 as described above) at the entrance of the final blade 20 in the lateral slide (3; 3 ').
