Definitions
- tulip means for the present invention any device facilitating the introduction of the apron into the guide rails and having means for supporting the stop of the roller shutter in the direction of the winding of the deck in the trunk and in to limit this winding.
- a rolling shutter of this type is known with the document DE 296 11 369 , comprising two flexible stops respectively mounted at each lateral end of the last deck blade.
- the V-shaped flexible stops the opening of the V being turned upwards, allow the automatic crossing of the tulips in the direction of the unwinding of the deck, by elastic compression of the branches of the V towards each other, and prevent the crossing of the tulips in the opposite direction of winding apron because the branches of the V resume under the effect of their elasticity their initial position.
- Such a shutter stop technology works pretty well, but has a disadvantage with respect to the disassembly of the apron: indeed, it is necessary in this case to use a suitable tool to reach the branches of the V inside the guide rails in an inaccessible place in the upper part of the opening, and compress them to allow the apron to cross the tulips in the direction of winding.
- a roller shutter is in principle provided with two stops respectively placed at each end of the last deck blade, the operation is to be repeated twice and at two different locations making disassembly of the apron even more delicate.
- the need for a compression of the elastic branches of the V induces an effort for the crossing of the tulips in the direction of the unfolding of the deck, an effort that can actually turn into a blocking of the deck if it is too important compared to the unwinding force of the deck, all the weaker at this time that almost the entire deck is wrapped in the trunk and that the weight of the deck then plays very little.
- DE 102 58 374 which relates to an abutment device for limiting the winding of the apron in a roller shutter box, comprising an abutment adopting a rigid T-shape having an extension intended to slide inside a shutter blade, the abutment being movable as a whole in longitudinal translation in the profile defining the last blade of the shutter.
- the stop can thus adopt two positions as follows: a first position in which the T is partially retracted inside the blade having a recess for this purpose so that it can not serve as a stop in the direction of winding roller shutter, and a second position in which the T is moved outwardly of the blade so that it can be arranged opposite the tulip and thus serve as a stop in the winding direction of the rolling shutter.
- the device comprises a return spring for blocking the entire stop in the second position.
- Such a rigid stop device loses the advantages of a stop with flexible branches.
- the document is still known DE 1,266,476 which relates to an articulated angle shutter device for roller shutter, comprising two rigid branches, a first abutment leg or movable branch, rotatable acting as a stop or abutment, and a second branch or fixed branch, adapted to be rigidly attached to the shutter rolling and supporting the rotating mobile branch.
- a rotation of 90 ° of the movable arm allows to put the latter in support on rigid advances integral fixed branch, thereby constituting an active position of the stop.
- the movable branch comprises a flexible blade which, in this active position, is clipped into a housing made in the fixed branch of the stop, to lock the active position of the movable arm. In the inactive position, the two branches of the abutment are aligned in the same plane.
- Such a rigid stop device loses the advantages of a stop with flexible branches.
- EP 0 092 122 which relates to a rolling shutter stop, mounted at the end of the blade, T-shaped, and rotatable along an axis of rotation parallel to the longitudinal axis of the blade corresponding to the main leg of the T, so that, according to two positions at 90 ° to one another, the stop blocks the winding of the flap or authorizes it.
- the device further comprises a system of spring and balls engaged with notches on the stop, to index the two positions.
- An alternative embodiment of the abutment according to this document is to move the stop T in translation along the longitudinal axis of the shutter blade. Such a rigid stop device loses the advantages of a stop with flexible branches.
- the present invention provides a stop with two positions, a rest position in which the crossing of the tulip is free in both directions of movement of the deck, that is to say it does not oppose any active resistance, except for a natural resistance of friction or sliding, and an active position in which the crossing in the opposite direction of the tulip is no longer possible, this position being advantageously used after the stop has passed the tulip in the direction of the unfolding of the apron ; the presence of two flexible branches between which said activation means are arranged, allows cooperation of the flexibility of the flexible branches of the stop with the activation means to establish the two positions of the stop.
- Such cooperation provides a stop with flexible branches, reinforced in that the activation means are adapted to be inserted between the branches defining the stop, thus able to define an abutment by obstacle, while allowing thanks to the flexibility of the branches, for example the possibilities of automatic return of the flexible branches of the stop in the rest position under the effect of the elasticity of these branches.
- Activation of the stop may be performed manually by an operator, or advantageously automatically according to a feature of the invention detailed below.
- the roller shutter according to the invention comprises means for guiding in translation of said activation means in a direction parallel to said lateral guide rails.
- This feature makes it possible to use the movement of the apron in the guide rails to automatically maneuver the activation means.
- said two flexible branches of the abutment adopt a shape of V whose longitudinal axis is parallel to said guide rails and whose opening of the flexible branches is turned downwards of said opening made in a building or similar.
- This characteristic allows a practical access of the activation means when they are arranged between the branches of the V, or manually by an operator because the opening of the V is directed towards the operator thus having a direct access to the activation means, either automatically as detailed below.
- said activation means comprise a movable element capable of coming into contact with the bottom of said opening made in a building or the like, said movable element being able to pass from the rest position to the active position when the hinged blade apron comes to bear at the bottom of said opening made in a building or the like.
- This feature allows an automatic activation of the activation means in the active position, by moving the apron which actuates the activation means during the end of its course when it arrives at low support, on the bottom of the opening or any other means of support low.
- This characteristic specifies a particularly advantageous mode of cooperation between a mobile element of the activation means and the flexible branches. V-shaped abutment, to obtain the two defined positions, rest and active.
- the shutter according to the invention comprises means for locking said activation means in the activated position.
- This feature ensures the maintenance of the activation means in the active position to ensure the active operation of the stop.
- the shutter according to the invention comprises means for unlocking said activation means, in order to allow the latter to pass from the active position to the rest position.
- This feature allows easy disassembly of the deck by placing in the rest position of the stop, allowing a crossing of the tulip without additional effort.
- the roller shutter according to the invention comprises means for driving said two flexible branches of the stop, to bring them closer to each other when said activation means pass from the active position to the position rest.
- This feature makes it possible to overcome a loosening of the elasticity of the flexible branches over time, by guaranteeing a return of the branches to the rest position even if these branches tend to remain in their active position despite the displacement of the activation means. rest position.
- the roller shutter according to the invention comprises means for connecting said activation means to said stop in the rest position, so that said activation means remain integral with it regardless of the adopted, resting or active position.
- This feature makes it possible to provide a compact and complete stop assembly, constituting a functional whole, and makes it possible to avoid, for example, the loss of an element of the assembly, in particular the loss of the activation means.
- said drive means and said connecting means are combined, and take the form of two lugs or pins respectively integral with said activation means or flexible branches.
- This feature is a particularly advantageous embodiment of the drive means and the connecting means combined.
- the roller blind according to the invention comprises means for embedding, in the lateral end of a blade of said apron, said abutment and said integral actuating means so as to form a blade tip.
- This feature allows quick and easy mounting of the stop in the appropriate deck blade, particularly the last blade that comes into contact with the bottom of the opening.
- a stop 3 preferably comprises two flexible branches 10 advantageously adopting a shape of V whose longitudinal axis 11 is parallel to the guide rails 1, and whose opening 12 of the flexible branches 10 is turned downwards 4 of the opening carried out in a building or the like; the activation means 7 are advantageously arranged between the two flexible branches 10.
- the V-shaped abutment 3 is advantageously fixed on the outer face of a plate 13 serving as a tip of the end of the blade on which the abutment 3 is mounted; in order to rigidly fix the abutment 3 at the end of a blade of the apron 6, embedding means 14 are arranged on the face of the plate 13 opposite to that on which the V-stop is fixed, as shown in FIGS. figures 5 or 7 .
- embedding means 14 are arranged on the face of the plate 13 opposite to that on which the V-stop is fixed, as shown in FIGS. figures 5 or 7 .
- These means in the known manner, for example, formed by one or more protuberances 18 adapted to engage, preferably in force, in the tubular end of the blade until the plate 13 comes into abutment on the lateral edge of said blade, playing its role of tip.
- the V-stop is attached to the plate by the root of the V as shown on the Figures 1 to 7 , so that the branches of the V can be free in a movement, preferably transversely along a plane perpendicular to the plane of the deck 6, to reach the two positions of rest and active stop 3, as will be explained later with the description activation means 7.
- the root of the V may be constituted by a cylinder 15 whose base is integral with the plate 13, or any other geometric shape adapted according to the dimensions of the flexible branches, in order to determine a sufficient grip of the stop on the plate 13.
- a rib 19 may, possibly where space permits, additionally attach the cylinder 15 or any other geometry adapted to the plate 13, on the opposite side to the departure of the flexible branches 10 from a generator of the cylinder, as shown for example on the figure 5 .
- each flexible branch 10 is provided with a stop face 16, substantially perpendicular to the outer surface of the branch of the V, and integral therewith, facing the end 17 of the tulip 2 in the example shown, either towards the root of the V, and intended to come into contact with the latter as shown on the figure 4 , in order to limit the winding of the apron in the trunk.
- the stop face 16 of each flexible branch 10 is for example formed by the face of a bearing prism 20, whose bases are for example triangular rectangles, one of the faces of the prism being attached to the outer surface of the branch flexible 10 and at the end thereof.
- the activation means 7 advantageously comprise a movable element 21, able to come into contact with the bottom of the opening made in a building or analogous, this movable element 21 being able to pass from the rest position to the active position when the apron 6 articulated blades comes to bear at the bottom 4 of the opening made in a building or the like, as shown in Figures 2 and 3 .
- the corner 23 can be hollowed in its center as shown for its lightening.
- the plate 22 of the movable element 21 cooperates with the space 29 for guiding the activation means 7 in a plane perpendicular to the plane of the deck 6, and the wedge 23 integral with the plate 22 cooperates with the faces internal flexible branches 10 for guiding the activation means 7 in a direction of this plane, namely the longitudinal direction of the V constituted by the branches 10.
- the part partially represented on the Figures 1 to 7 advantageously comprises locking means 31 of the activation means 7 in the activated position.
- These locking means 31 may for example take the form of two projections 32 respectively disposed on the two inner faces of the two flexible branches 10, respectively able to penetrate into two complementary housing 33 formed on the movable member 21, for example on the corner 23, under the effect of an elastic return of the flexible branches, when the movable element 21 is in the active position, that is to say in place inside the V, the branches 10 of the latter then being sufficiently spaced for that the stop faces 16 are vis-à-vis the ends of the tulip, as shown on the figure 4 .
- the part partially represented on the Figures 1 to 7 comprises advantageously means for unlocking the activation means 7, to allow the passage of the latter from the locked active position to the rest position.
- These unlocking means comprise a suitable shape of the projections 32 and complementary housing 33 constituting the locking means 31 so that, when the projections 32 are in the recesses 33, respectively, they can emerge by pulling the movable element 21 in the opposite direction to that which allowed the locking of this movable element 21 in the abutment 3.
- the appropriate form of the projections will for example be a prismatic shape extending over the width of a flexible strip 10, the cross section is for example triangular and having a stop face parallel to an opposite complementary face of the housing 33, having an inclination angle for example between 30 ° and 60 ° relative to the longitudinal axis of the V branches of the stop 3.
- pulling the movable member 21 to extract it from the V will separate the branches 10 from each other so that the protrusions 32 are extracted from the box 33.
- the unlocking means furthermore advantageously comprise an opening 34 made in the movable element 21 in the lower part thereof, as shown in FIGS. Figures 1 to 7 , in order to allow the passage of a suitable hook-type tool in the opening 34, to exert a pull down and thus unlock the activation means 7 to make the abutment 3 passive (rest position).
- This opening can be achieved by crossing the plate 22 of the movable member 21 and the corner 23 as shown.
- the unlocking of the activation means by traction on the movable element 21, can be performed regardless of the position of the shutter in the opening of the building or the like, and in particular according to the most appropriate position for the operator.
- the opening 34 will preferably be performed in an area of the movable member 21 closest to the bearing face 27, in order to be easily accessible to the operator. It should be noted that this opening 34 may be placed near the lower edge of the final blade, and therefore will be much more accessible than the branches of the V-stop themselves.
- At least one additional projection similar to a projection 32 described above, associated respectively with at least one housing (not shown) additional like a housing 33 described above, can be formed respectively on the face of the plate 22, opposite the fixing face of the wedge 23, and on the plate 13 of the abutment 3 opposite the plate 22.
- This additional projection and housing may strengthen the locking means 31 described above, by constituting an additional locking means of the movable member 21 on the stop 3 in a plane transverse to the plane of the deck 6.
- This additional locking means can intervene in the two active and passive positions of the movable element 21, for example by producing a projection on the plate 13 and two corresponding housings on the plate 22, one for each position distinct from the movable element .
- the part partially represented on the Figures 1 to 7 advantageously comprises connecting means 35 of the activation means 7, to the stop 3, in the rest position, so that the activation means 7 remain integral with it regardless of the position adopted, rest or active .
- the locking means 31 rigidly and removably connect the activation means 7 to the stop 3 in the active position.
- connection means 35 of the activation means 7, to the abutment 3, in the rest position advantageously comprise two lugs 36 attached to the plate 22 of the movable element 21 and extending perpendicularly thereto towards the branches flexible 10, so as to respectively bear on the stop faces 16 of each flexible branch 10 when the movable member 21 is in the rest position, as shown in the figures 5 , 1 , and 2 , thus preventing a complete dissociation of the activation means 7 of the abutment 3.
- the two lugs 36 may advantageously serve, for a part of the displacement at least, for guiding the movable element 21 on the two flexible branches 10, the latter being trapped between the corner 23 on their inner faces, and respectively the two lugs 36 on their outer faces, as shown in FIG. figure 6 .
- the two lugs 36 can be away from the branches, as shown on the figure 4 .
- the two lugs 36 may advantageously take the form of two bumpers perpendicular to the plate 22 and each having a bearing surface 40, for example flat or other surface suitable for this function, vis-à-vis the two outer surfaces of the two branches flexible 10 respectively.
- This bearing surface 40 also serves to ensure the return of the flexible branches 10 in the rest position when the movable member 21 moves from the active position to the rest position, that is to say ensure the approximation of flexible branches 10 towards each other.
- the lugs 36 guarantee the return of the flexible branches 10 in the rest position by forcing them to approach each other during the movement of the movable element 21 towards the rest position.
- the two lugs 36 are preferably placed in the tapered zone of the end 41 of the wedge 23 and on either side thereof, as shown in FIGS.
- the distance separating the two lugs 36 is fixed, in a direction perpendicular to the surface of the deck 6, and it is found that when the wedge 23 passes from the rest position to the active position, the end of the branches 10 is spacing apart from one another under the effect of the wedge 23, but the lugs 36 are simultaneously approaching the root of the flexible branches 10, so that the distance separating the flexible branches 10 remains substantially constant during the movement of the movable element 21 at the two lugs 36: and the fixed spacing of the two lugs 36 does not interfere or oppose, the variable spacing of the flexible legs 10 during the transition from the rest position to the position active stopper 3.
- the lugs 36 via their support surfaces 40 at least partially supported during the transition from a rest state to an active state of the stop 3 or vice versa, participate in the guide means 28 in translation of the activation means 7 in a direction parallel to the lateral guide rails 1.
- the Figures 1 to 4 show that the distance separating the two outer surfaces of the flexible branches 10 is substantially the same at the end of the branches where the bearing faces 16 are and in the rest position on the one hand, and at the root of the flexible branches 10 and in the active position on the other hand. It can be assumed as explained above that this distance is slightly lower in the second situation with respect to the first, so that the lugs 36 no longer touch the flexible branches 10 in the active position.
- the connecting means of the activation means to the stop are constituted by the pins 136 housed and guided in the slots 150 and 151 which constitute a limit of the displacement of the movable element 121 towards the position of rest when the upper end of the lights abuts against the pins 136 formed on the flexible branches in the rest position.
- the lights 150 and 151 assist the wedge for the spacing of the flexible branches 110, the wedge 123 giving the stop 103 its resistance in the active position.
- the abutment 3 or 103 and the activation means 7 or 107 may be made of rigid plastic material having elastic properties for the flexible branches 10 or 110, and obtained by molding.
- the stop 3, 103 the plate 13, 113 and the embedding means 14, 114 are advantageously made integrally in a first piece, and the activation means comprising the plate 22, 122 and the wedge 23, 123 may advantageously be made in one piece in a single piece, linked to the first by a link having at least one degree of freedom in translation as explained above.
- the abutment assembly 3, 103 and activation means 7, 107 is a push-fit end piece of rolling shutter deck blade, as described above.
- the apron can then be unwound in the opening of the building or the like, by crossing the tulips, and the arrival of the deck at the bottom of the opening will automatically place the activation means in the active position as explained above; when the apron is raised the active stops come to limit the winding of the apron in the trunk.
- the active positioning of the activation means of the stop can be performed manually by an operator before the arrival at the end of travel of the apron at the bottom of the opening.

Abstract
Description
La présente invention se rapporte au domaine de la construction, plus particulièrement à un volet roulant destiné à être monté dans une ouverture réalisée dans un bâtiment ou analogue, ledit volet roulant comportant :
- un tablier à lames articulées apte à se dérouler dans ladite ouverture et à s'enrouler dans un coffre voisin de ladite ouverture,
- deux rails de guidage latéraux dudit tablier, fixés respectivement sur les deux montants verticaux opposés de ladite ouverture,
- deux tulipes de guidage, pour guider l'entrée dudit tablier dans lesdits rails de guidage, respectivement,
- au moins une butée pour limiter l'enroulement dudit tablier dans ledit coffre, disposée à une extrémité d'une lame dudit tablier, apte à permettre le franchissement d'au moins une desdites deux tulipes de guidage dans le sens du déroulement du tablier, et l'empêchement du franchissement de ladite au moins une tulipe de guidage dans le sens de l'enroulement du tablier.
- an apron with articulated blades adapted to unfold in said opening and to be wound in a box near said opening,
- two lateral guide rails of said apron, respectively fixed on the two opposite vertical uprights of said opening,
- two guide tulips for guiding the entrance of said apron into said guide rails, respectively,
- at least one stop for limiting the winding of said apron in said trunk, disposed at one end of a blade of said apron, adapted to allow the crossing of at least one of said two guide tulips in the direction of the unwinding of the apron, and preventing the crossing of said at least one guide tulip in the direction of the winding of the deck.
Par tulipe, on entend pour le présent mémoire tout dispositif facilitant l'introduction du tablier dans les rails de guidage et comportant des moyens servant d'appui à la butée du volet roulant dans le sens de l'enroulement du tablier dans le coffre et en vue de limiter cet enroulement.By tulip means for the present invention any device facilitating the introduction of the apron into the guide rails and having means for supporting the stop of the roller shutter in the direction of the winding of the deck in the trunk and in to limit this winding.
On connaît un volet roulant de ce type avec le document
Une telle technologie de butée de volet roulant fonctionne assez bien, mais présente un inconvénient relativement au démontage du tablier : en effet, il est nécessaire dans ce cas d'utiliser un outil approprié permettant d'atteindre les branches du V à l'intérieur des rails de guidage dans un endroit peu accessible en partie haute de l'ouverture, et de les comprimer afin de permettre au tablier le franchissement des tulipes dans le sens de l'enroulement. En outre, un volet roulant étant en principe doté de deux butées placées respectivement à chaque extrémité de la dernière lame du tablier, l'opération est à renouveler deux fois et à deux endroits différents rendant le démontage du tablier encore plus délicat.Such a shutter stop technology works pretty well, but has a disadvantage with respect to the disassembly of the apron: indeed, it is necessary in this case to use a suitable tool to reach the branches of the V inside the guide rails in an inaccessible place in the upper part of the opening, and compress them to allow the apron to cross the tulips in the direction of winding. In addition, a roller shutter is in principle provided with two stops respectively placed at each end of the last deck blade, the operation is to be repeated twice and at two different locations making disassembly of the apron even more delicate.
En outre, la nécessité d'une compression des branches élastiques du V induit un effort pour le franchissement des tulipes dans le sens du déroulement du tablier, effort qui peut en fait se transformer en blocage du tablier s'il est trop important par rapport à la force de déroulement du tablier, d'autant plus faible à ce moment que la quasi totalité du tablier se trouve enroulée dans le coffre et que le poids du tablier joue alors très peu.In addition, the need for a compression of the elastic branches of the V induces an effort for the crossing of the tulips in the direction of the unfolding of the deck, an effort that can actually turn into a blocking of the deck if it is too important compared to the unwinding force of the deck, all the weaker at this time that almost the entire deck is wrapped in the trunk and that the weight of the deck then plays very little.

La présente invention se propose de pallier ces inconvénients, et d'apporter d'autres avantages. Plus précisément, elle consiste en un volet roulant tel que défini en début de mémoire et comprenant en outre des moyens d'activation de ladite au moins une butée, coopérant avec cette dernière en sorte qu'elle soit apte à adopter les deux positions distinctes suivantes :
- une première position, lorsque lesdits moyens d'activation sont au repos, dite position de repos, permettant un franchissement libre par la butée, de ladite au moins une tulipe de guidage,
- une deuxième position, lorsque lesdits moyens d'activation sont activés, dite position active, empêchant le franchissement par la butée, de ladite au moins une tulipe de guidage,
- a first position, when said activation means are at rest, said rest position, allowing a free crossing by the stop, of said at least one guide tulip,
- a second position, when said activation means are activated, said active position, preventing crossing by the stop, of said at least one guide tulip,
Ainsi, la présente invention propose une butée à deux positions, une position de repos dans laquelle le franchissement de la tulippe est libre, dans les deux sens de déplacement du tablier, c'est à dire qu'il n'oppose aucune résistance active, exceptée une résistance naturelle de frottement ou de glissement, et une position active dans laquelle le franchissement en sens inverse de la tulipe n'est plus possible, cette position étant avantageusement utilisée après que la butée ait franchi la tulipe dans le sens du déroulement du tablier ; la présence de deux branches flexibles entre lesquelles lesdits moyens d'activation sont disposés, permet une coopération de la flexibilité des branches flexibles de la butée avec les moyens d'activation pour établir les deux positions de la butée. Une telle coopération offre une butée à branches flexibles, renforcée en ce que les moyens d'activation sont aptes à être insérés entre les branches définissant la butée, donc aptes à définir une butée par obstacle, tout en permettant grâce à la flexibilité des branches, par exemple des possibilités de retour automatique des branches flexibles de la butée en position de repos sous l'effet de l'élasticité de ces branches. L'activation de la butée peut être effectuée manuellement par un opérateur, ou avantageusement automatiquement selon une caractéristique de l'invention détaillée plus loin.Thus, the present invention provides a stop with two positions, a rest position in which the crossing of the tulip is free in both directions of movement of the deck, that is to say it does not oppose any active resistance, except for a natural resistance of friction or sliding, and an active position in which the crossing in the opposite direction of the tulip is no longer possible, this position being advantageously used after the stop has passed the tulip in the direction of the unfolding of the apron ; the presence of two flexible branches between which said activation means are arranged, allows cooperation of the flexibility of the flexible branches of the stop with the activation means to establish the two positions of the stop. Such cooperation provides a stop with flexible branches, reinforced in that the activation means are adapted to be inserted between the branches defining the stop, thus able to define an abutment by obstacle, while allowing thanks to the flexibility of the branches, for example the possibilities of automatic return of the flexible branches of the stop in the rest position under the effect of the elasticity of these branches.

Par commodité de représentation, et pour simplifier, cette dernière lame n'a pas été représentée sur les
Une butée 3 comprend de préférence deux branches flexibles 10 adoptant avantageusement une forme de V dont l'axe longitudinal 11 est parallèle aux rails 1 de guidage, et dont l'ouverture 12 des branches flexibles 10 est tournée vers le bas 4 de l'ouverture réalisée dans un bâtiment ou analogue ; les moyens d'activation 7 sont avantageusement disposés entre les deux branches flexibles 10.A
La butée 3 en forme de V est avantageusement fixée sur la face extérieure d'une plaque 13 faisant office d'embout de l'extrémité de la lame sur laquelle est montée la butée 3 ; afin de fixer rigidement la butée 3 à l'extrémité d'une lame du tablier 6, des moyens d'encastrement 14 sont disposés sur la face de la plaque 13 opposée à celle sur laquelle est fixée la butée en V, comme représenté sur les
L'extrémité extérieure de chaque branche flexible 10 est munie d'une face d'arrêt 16, sensiblement perpendiculaire à la surface extérieure de la branche du V, et solidaire de celle-ci, tournée vers l'extrémité 17 de la tulipe 2 dans l'exemple représenté, soit vers la racine du V, et destinée à venir en contact avec cette dernière comme montré sur la
Les moyens d'activation 7 comportent avantageusement un élément mobile 21, apte à venir en contact avec le bas de l'ouverture réalisée dans un bâtiment ou analogue, cet élément mobile 21 étant apte à passer de la position de repos à la position active lorsque le tablier 6 à lames articulées arrive en appui au bas 4 de l'ouverture réalisée dans un bâtiment ou analogue, comme représenté sur les
Cet élément mobile 21 comprend avantageusement :
une plaque 22 apte à coulisser suivant l'axe longitudinal 11 du V, avantageusement confondu avec l'axe longitudinal des rails de guidage, dans l'espace 29 crée entre le bord des branches flexibles 10 etla plaque 13 de la butée 3,un coin 23 rattaché à laplaque 22, qui présente deux faces 24, 25 formant coin, perpendiculaires à laopposées plaque 22, destinées à pénétrer entre les deux branches flexibles 10 de la butée 3 afin de les écarter l'une de l'autre pour placerla butée 3 en position active, lors d'un déplacement en translation de l'élément mobile 21 suivant l'axe du V, comme représenté sur lafigure 3 avec la flèche 26,une face d'appui 27 tournée vers le bas 4 de l'ouverture ou analogue, destinée à venir au contact du bas de l'ouverture ou d'un élément similaire, afin de déplacer l'élément mobile 21 en translation automatiquement pendant le déplacement du tablier en fin de déroulement de celui-ci.
- a
plate 22 capable of sliding along thelongitudinal axis 11 of the V, advantageously coinciding with the longitudinal axis of the guide rails, in thespace 29 created between the edge of theflexible branches 10 and theplate 13 of theabutment 3, - a
wedge 23 attached to theplate 22, which has two 24, 25 forming a wedge, perpendicular to theopposite faces plate 22, intended to penetrate between the twoflexible branches 10 of thestop 3 in order to separate them from each other to place thestopper 3 in the active position, during a displacement in translation of themovable element 21 along the axis of the V, as shown in FIG.figure 3 witharrow 26, - a bearing
face 27 facing downwards 4 of the opening or the like, intended to come into contact with the bottom of the opening or a similar element, in order to move themobile element 21 in translation automatically during the displacement apron at the end of this one.
Le coin 23 peut être évidé en son centre comme représenté en vue de son allègement. L'espace 29 crée entre le bord des branches flexibles 10 et la plaque 13 de la butée 3 d'une part, et l'espace 30 compris entre les branches flexibles 10 d'autre part, servent de moyens de guidage 28 en translation des moyens d'activation 7 suivant une direction parallèle aux rails 1 de guidage latéraux. En effet, la plaque 22 de l'élément mobile 21 coopère avec l'espace 29 pour un guidage des moyens d'activation 7 dans un plan perpendiculaire au plan du tablier 6, et le coin 23 solidaire de la plaque 22 coopère avec les faces internes des branches flexibles 10 pour un guidage des moyens d'activation 7 suivant une direction de ce plan, à savoir la direction longitudinale du V constitué par les branches 10.The
Ainsi,
- lorsque les moyens d'activation 7 sont au repos, l'élément mobile 21 est disposé entre les branches flexibles 10 de la butée 3, à l'entrée du V, comme par exemple représenté sur les
figures 1 ou 2 ; de telle sorte que ces branches flexibles 10 soient proches l'une de l'autre selon une direction transversale perpendiculaire à l'axe longitudinal des rails 1 de guidage, afin de placer la butée 3 en position de repos en sorte que le franchissement de la tulipe 2 de guidage correspondante soit possible dans les deux sens de déplacement du tablier (enroulement et déroulement), et - lorsque les moyens d'activation 7 sont activés, l'élément mobile 21 est disposé entre les branches flexibles 10 de la butée 3, vers le fond du V, comme représenté sur la
figure 3 ou 4 , de telle sorte que ces branches flexibles 10 soient écartées l'une de l'autre selon la direction transversale perpendiculaire à l'axe longitudinal des rails 1 de guidage, afin d'activer la butée 3 pour limiter l'enroulement du tablier 6 dans le coffre, en empêchant le franchissement de la tulipe 2 de guidage correspondante dans le sens de l'enroulement.
- when the activation means 7 are at rest, the
movable element 21 is arranged between theflexible branches 10 of theabutment 3, at the entrance of the V, as for example represented on thefigures 1 or2 ; such that theseflexible branches 10 are close to one the other in a transverse direction perpendicular to the longitudinal axis of theguide rails 1, in order to place thestop 3 in the rest position so that the crossing of thecorresponding guide rod 2 is possible in both directions of travel apron (winding and unwinding), and - when the activation means 7 are activated, the
movable element 21 is disposed between theflexible branches 10 of theabutment 3 towards the bottom of the V, as shown in FIG.figure 3 or4 , such that theseflexible branches 10 are spaced from each other in the transverse direction perpendicular to the longitudinal axis of theguide rails 1, in order to activate thestop 3 to limit the winding of thedeck 6 in the trunk, preventing the crossing of thecorresponding guide rod 2 in the direction of winding.

Les moyens de déverrouillage comprennent en outre avantageusement une ouverture 34 réalisée dans l'élément mobile 21 dans la partie inférieure de celui-ci, comme représenté sur les
Au moins une saillie (non représentée) supplémentaire semblable à une saillie 32 décrite ci-dessus, associée respectivement à au moins un logement (non représenté) supplémentaire semblable à un logement 33 décrit ci-dessus, peuvent être formés respectivement sur la face de la plaque 22, opposée à la face de fixation du coin 23, et sur la plaque 13 de la butée 3 en regard de la plaque 22. Cet ensemble saillie et logement supplémentaires peut venir renforcer les moyens de verrouillage 31 décrits plus haut, en constituant un moyen de verrouillage supplémentaire de l'élément mobile 21 sur la butée 3 dans un plan transversal au plan du tablier 6. Ce moyen de verrouillage supplémentaire peut intervenir dans les deux positions, active et passive, de l'élément mobile 21, par exemple par la réalisation d'une saillie sur la plaque 13 et de deux logements correspondants sur la plaque 22, un pour chaque position distincte de l'élément mobile.At least one additional projection (not shown) similar to a

A l'effet de guidage de l'élément mobile 21 sur les branches flexibles 10, les deux ergots 36 peuvent avantageusement adopter la forme de deux butoirs perpendiculaires à la plaque 22 et présentant chacun une surface d'appui 40, par exemple plane ou autre surface appropriée pour cette fonction, en vis-à-vis des deux surfaces externes des deux branches flexibles 10 respectivement. Cette surface d'appui 40 a en outre pour fonction d'assurer le retour des branches flexibles 10 en position de repos lorsque l'élément mobile 21 passe de la position active à la position de repos, c'est à dire assurer le rapprochement des branches flexibles 10 l'une vers l'autre. Une telle caractéristique est particulièrement avantageuse dans la mesure ou les branches flexibles 10 pourraient, avec le temps, perdre de leur élasticité et avoir tendance à rester écartées l'une de l'autre même en cas de retrait du coin 23 hors du V : dans ce cas, les ergots 36 garantissent le retour des branches flexibles 10 en position de repos en les contraignant à se rapprocher l'une de l'autre durant le déplacement de l'élément mobile 21 vers la position de repos. Les deux ergots 36 seront de préférence placés dans la zone effilée de l'extrémité 41 du coin 23 et de part et d'autre de celle-ci, comme représenté sur les
La distance séparant les deux ergots 36 est fixe, selon une direction perpendiculaire à la surface du tablier 6, et l'on constate que lorsque le coin 23 passe de la position de repos à la position active, l'extrémité des branches 10 s'écartent l'une de l'autre sous l'effet du coin 23, mais les ergots 36 se rapprochent simultanément de la racine des branches flexibles 10, de telle sorte que la distance séparant les branches flexibles 10 reste sensiblement constante durant le déplacement de l'élément mobile 21 au niveau des deux ergots 36 : ainsi l'écartement fixe des deux ergots 36 ne vient pas gêner, ni s'opposer à, l'écartement variable des branches flexibles 10 durant le passage de la position de repos à la position active de la butée 3.The distance separating the two
En outre, il y a lieu de noter que les ergots 36 via leur surfaces d'appui 40 en appui au moins partiellement durant le passage d'un état de repos à un état actif de la butée 3 ou inversement, participent aux moyens de guidage 28 en translation des moyens d'activation 7 suivant une direction parallèle aux rails 1 de guidage latéraux.In addition, it should be noted that the

Figures 8 and 9 , the locking means take the form of twoprojections 132 respectively disposed on the two 124, 125 forming a wedge of theopposite faces movable member 121, able respectively to penetrate into twocomplementary housings 133 formed on the two inner faces of the twoflexible branches 110.
Ainsi, dans ce deuxième mode, les pions 136 sont logés dans les lumières 150 et 151 qui obligent le rabattement des branches flexibles 110 en position de repos et en outre l'écartement de ces branches en position active selon que l'élément mobile 121 passe de la position de repos à la position active ou inversement lors d'un déplacement en translation suivant l'axe longitudinal du V. L'inclinaison des lumières est telle qu'elles forment entre elles un angle apte à faire passer les branches flexibles 110 de la position écartée à la position rapprochée d'une extrémité à l'autre des lumières 150 et 151, correspondant sensiblement à la course de l'élément mobile 121. Comme représenté sur les
- les extrémités supérieures des lumières sont rapprochées l'une de l'autre, cette zone correspondant au rapprochement maximal des branches flexibles l'une de l'autre, et donc à la position de repos de l'élément mobile, et
- les extrémités inférieures des lumières 150
et 151 sont écartées l'une de l'autre, cette zone correspondant à l'éloignement maximal des branches flexibles l'une de l'autre, et donc à la position active de l'élément mobile, - les lumières 150
et 151 étant sensiblement parallèles aux deux facesopposées 124et 125 ducoin 123.
- the upper ends of the lights are brought closer to one another, this zone corresponding to the maximum approach of the flexible branches of one another, and therefore to the rest position of the movable element, and
- the lower ends of the
150 and 151 are spaced from one another, this zone corresponding to the maximum distance of the flexible branches from each other, and therefore to the active position of the movable element,lights - the
150 and 151 being substantially parallel to the twolights 124 and 125 of theopposite faces corner 123.
Dans ce deuxième mode de réalisation, les moyens de liaison des moyens d'activation à la butée sont constitués par les pions 136 logés et guidés dans les lumières 150 et 151 qui constituent une limite du déplacement de l'élément mobile 121 vers la position de repos lorsque l'extrémité supérieure des lumières vient buter contre les pions 136 formés sur les branches flexible en position de repos. Lors du passage de l'élément mobile 121 de la position de repos à la position active, les lumières 150 et 151 assistent le coin pour l'écartement des branches flexibles 110, le coin 123 conférant à la butée 103 sa résistance en position active.In this second embodiment, the connecting means of the activation means to the stop are constituted by the
On remarquera que dans ce deuxième mode de réalisation, les faces d'appui 116 de la butée 103 restent libres de tout ergot en position de repos.Note that in this second embodiment, the bearing faces 116 of the
La butée 3 ou 103 ainsi que les moyens d'activation 7 ou 107 peuvent être réalisés en matière plastique rigide présentant des propriétés d'élasticité pour les branches flexibles 10 ou 110, et obtenus par moulage. La butée 3, 103 la plaque 13, 113 et les moyens d'encastrement 14, 114 sont avantageusement réalisés de manière monobloc en une première pièce, et les moyens d'activation comportant la plaque 22, 122 et le coin 23, 123 peuvent être avantageusement réalisés de manière monobloc en une deuxième pièce, liée à la première par une liaison comportant au moins un degré de liberté en translation comme expliqué plus haut.The
L'ensemble butée 3, 103 et moyens d'activation 7, 107 constitue un embout emboîtable en bout de lame de tablier de volet roulant, comme décrit plus haut. Lors du montage du volet roulant, un tel embout est placé à chaque extrémité de la lame appropriée, de préférence la dernière, en position de repos ; le tablier peut alors être déroulé dans l'ouverture du bâtiment ou analogue, en franchissant les tulipes, et l'arrivée du tablier en bas de l'ouverture placera automatiquement les moyens d'activation en position active comme expliqué plus haut ; lorsque le tablier est remonté les butées actives viennent limiter l'enroulement du tablier dans le coffre. II est à noter que la mise en position active des moyens d'activation de la butée peut être effectuée manuellement par un opérateur avant l'arrivée en fin de course du tablier au bas de l'ouverture.The
