Definitions

  • the present invention relates to a closing device comprising a flexible curtain, such as that a tarpaulin, the lateral edges of which are guided in guide paths allowing the curtain to be moved between a closed position and a position opening.
  • the lower edge of the latter is provided with a ballast bar extending over the entire width of the curtain to allow the closure of the latter essentially under the weight of this ballast bar and maintain it in a tense state.
  • ballast bar has various significant disadvantages. So, as a result of its inertia, the opening and closing speeds are limited and special precautions should be sockets for braking the upward movement and lowering the curtain sufficient time before stopping this last. In addition, the weight of such a ballast bar requires relatively large energy to bring the curtain in its open position. Finally, means reliable safety devices must be provided in the curtain control to prevent accidents when a anyone or any object is below the curtain when it descends to its closed position.
  • Document FR-A-2 683 258 relates to a door with a curtain that can move along a vertical direction.
  • the curtain of this door has side edges made of flexible and elastic sheets to improve the tightness of this door.
  • One of the essential purposes of this invention is to provide a device for closing a flexible curtain that no longer requires a bar stiffening and ballasting.
  • the side edges of the curtain are substantially incompressible or made incompressible along their length, drive means being provided allowing to cause a pushing force on these edges according to the longitudinal direction of these in their paths guide to move the curtain to its position closing and possibly back to its position opening.
  • the curtain is provided, at or near the aforementioned side edges, of a succession of substantially rigid organs according to the longitudinal direction of these lateral edges, these organs can lean against each other according to the direction of these lateral edges, and preferably being able be articulated with each other so as to allow the curtain to roll up or bend in its open position.
  • the rigid members surround the side edges of the curtain, projecting from relative to the surface of the latter, this projection being maintained in the aforementioned guideways and is moving into these.
  • the curtain has, at proximity of at least one of its lateral edges and outside the aforementioned guideways, means for stiffening to make the above edges substantially incompressible in the direction of their length, these stiffening means being advantageously formed by a toothed belt integral with the curtain and extending the along at least one of the lateral edges of the latter, aforementioned drive means cooperating with said toothed belt.
  • the following closing device the invention and including some embodiments particular have been shown in the accompanying figures comprises a flexible curtain 1, the lateral edges 2 of which are guided in guideways 3 to allow the curtain 1 to move between a closed position and an open position. These edges are preferably protruding from the plane of the curtain so as to allow them to be easily maintained in the paths of guide.
  • any planar element which may form a closure or a separation and can wrap around an axis or fold such as a tarp, a plastic strip, etc ..., intended for the closure of a bay, for the realization a partition wall, roof, swimming pool or the realization of an awning.
  • a pronounced preference is given to watertight doors therefore comprising a curtain which moves between two vertical guide paths.
  • the closure is characterized by the fact that the side edges 2 of the curtain 1 are substantially incompressible or made incompressible in the sense of their length, so as to allow to apply on these edges a longitudinal thrust in the guideways 3 without them being able to form gathers that are likely to block these edges in these guide paths.
  • training means 4 are also provided for acting on these edges 2 in their guideways 3 to bring the curtain 1 in its closed position and possibly in its open position.
  • the means 4 are arranged to allow create a pushing force on the side edges 2 of the curtain 1 in the longitudinal direction of these last, causing the curtain to move towards its closed position, as shown in Figure 1.
  • the opening of the curtain 1 is caused by a spring 31 fixed between the free end of a belt 32 and a fixed point at base 33.
  • this belt 32 is wound on a pulley 34 wedged on a drive shaft 20 which is actuated by a gear motor 36, the latter being controlled from a control box 37.
  • the spring 31 is brought into a stretched state when curtain 1 is in its closed position, as shown in figure 1. This thus allows the automatic winding of the curtain towards its open position when unlocked in this closed position.
  • the curtain 1 is formed of a tarpaulin in which are arranged three windows 38 made in one transparent plastic material which is rolled up in its open position in a square section box 39 closed at both ends by flanges 40.
  • spiral guideways 18 extend into the extension of straight guideways 3.
  • the curtain 1 is provided, at its lateral edges 2, with a succession of members projections 5 which are at least rigid in the direction longitudinal of these lateral edges 2.
  • These organs 5 lean against each other following this longitudinal direction and are hinged together by relation to others, so as to allow the winding of the curtain 1 inside the box 39, when it is brought in its open position.
  • these rigid members 5 surround the lateral edges 2 of the curtain 1 by forming a projection 6 on either side by compared to the plan of the latter and slide with a certain friction in guideways 3 and 18, so to prevent the curtain from moving between the position opening and closing under its own weight.
  • This has as an advantage that it is not necessary to provide special braking means for the limit switches of the curtain.
  • the side edges 2 of the curtain 1 have a substantially continuous bead 7 around which are fixed rigid bodies 5.
  • this bead comprises a hollow pipe 8 which can for example contain a fluid or conductor of electric current.
  • this pipe contains a gas, such air 41, a pneumatic safety system any not shown.
  • a gas such air 41
  • pneumatic safety system any not shown.
  • Such conduct 8 is therefore perfectly protected as well by rigid bodies 5 only by the guideways 3 in which these members are moving.
  • the rigid members 5 have the appearance of protruding sleeves 6 having in their wall a longitudinal slot 9 by which the curtain 1 comes out of the sleeves thus defining two wings 10 and 11 extending on either side of this latest.
  • Wing 10 has a length in the direction side edges 2 of the curtain lower than that of the other wing 11, so that a recess 12 is formed on one side of the curtain 1 between two consecutive members 5 thus allowing the bending of the edge 2 transversely to the plan of the curtain on the above side (see Figure 9).
  • Others wings 11 of these members 5 bearing end to end against the others in the longitudinal direction of the edges side 2 of curtain 1 (see Figure 8).
  • the shortest wing 10 of the rigid member 5 has a length equal to half that of the other wing 11 and is symmetrically relative to this other wing 11, so as to thus form opposite the latter and on either side of the most short 10 a recess 12 having the length of a quarter that of wing 11.
  • Figure 7 illustrates, in a way schematic, the behavior of these rigid organs specific 5 when rolling up the curtain. We aknowledge that the rolled side edges can gather freely in the recesses 12 thus facilitating the bending of these.
  • wing 10 located on the side of the center of curvature of spiral guideway 19 east shorter than the opposite wing 11 of the rigid members 5 also makes it possible to avoid the displacement of these organs 5 on the side edges 2 of the curtain 1 during winding of the latter in its open position. Indeed, as clearly illustrated in Figure 7, two organs rigid lines are articulated along the neutral axis of side edges 2 while remaining in contact with each other the others at location 11 'located on this neutral axis.
  • the sleeves 6 have a section rectangular and are mounted with some play transverse to curtain 1 in the paths of spiral guidance 18. Thus, a certain translation of the edges 2 of the curtain is possible in the plane of the flanges 40.
  • the radial distance between the turns of the guideways 18 is such that in the rolled up position, the layers of the curtain coiled do not touch, as shown clearly to Figures 4 to 7.
  • Spiral guideways 18 delimit a substantially tubular channel 22, of preference of polygonal section, having in its wall 23, on the side of the curtain 1, a longitudinal slot 24 for the passage of the latter.
  • the central spiral axis 25 of this channel 22 being located in the plane of symmetry of the slot 24, while the curtain extends along plane 27.
  • Figure 10 shows the position of the rigid members 5 in the guideways 18 during unwinding of the curtain towards its closed position.
  • the center of curvature, which is located on axis 17 is located in this case on the right side of figure 10.
  • the side edges 2 of curtain 1 are applied against the face outside of the guideways with respect to this center curvature.
  • the drive means 4 comprise near the flanges 40, inside the box 39, a telescopic arm 19 cooperating with the end upper side edges of curtain 1.
  • This telescopic arm 19 is mounted transversely on a drive shaft 20 extending along the aforementioned axis 17 and is fixed to a bar 21 parallel to this shaft 20.
  • This bar cooperates with the end of the side edges 2 of the curtain, which are engaged in the spiral guideways 18 by through a connecting piece 35, on the one hand, fixed to the transverse edge 41 of the curtain 1 and, on the other hand, sliding in a longitudinal groove 42 of this bar 21.
  • the telescopic arm 19 includes two U-shaped guide pieces parallel 43, fixed on either side on the shaft 20, in which sliding tubes are mounted square section 43 one end of which is rendered integral with the bar 21, which is also formed of a tube square.
  • the shaft 20 is brought into rotation in the direction of arrow 46 by the motor 36 and the intermediate piece 35 pushes on the lateral edge 2 in the direction of its length, while the bar 44 undergoes a move in the direction of arrow 47.
  • the connecting piece 35 can slide in the groove 42 of the bar 21 during the unwinding of the curtain.
  • the curtain may open either by the spring 31, as already described above, or by driving the shaft 20 in the opposite direction to the arrow 46.
  • the guideways rectilinear 3 comprise a U-shaped profile 48 made in a semi-elastic material, so as to allow, when a pulling force is exerted on the curtain 1 in the direction arrow F exceeding a certain limit, to clear the lateral edges 2 of the curtain of the guide tracks 3.
  • a pulling force is exerted on the curtain 1 in the direction arrow F exceeding a certain limit, to clear the lateral edges 2 of the curtain of the guide tracks 3.
  • Such force could for example result from the fact that a vehicle hangs curtain 1 when it is still in its closed position.
  • the base of the U-shaped profile 48 is maintained in a metal support 50 also having a U-shaped section.
  • Figures 14 and 15 show very schematically a second embodiment of the closing device according to the invention.
  • edges side 2 have the look of a hinged chain moving in the guideways 3.
  • the straight guide path 3 is interrupted before entering the box 40 and, at this place of interruption, on either side of the lateral edge 2, are provided the drive means 4.
  • These means drive include two pairs of gears 51 on which moves an endless belt 52 provided externally of teeth capable of engaging in the links of the articulation chain 15.
  • Figure 16 is a representation simplified of a third embodiment of the closing device according to the invention.
  • the curtain 1 is brought into an open position horizontal, being guided along a ceiling 53 in guide tracks 18, after having undergone a deviation 90 °.
  • the drive means 4 include an endless chain transmission 16 capable of move along the horizontal part of the paths guide 18 in a back-and-forth movement, as indicated by the arrows 54.
  • a connecting piece 35 is provided between the upper end of the side edges 2 of the curtain and chain 16 therefore allowing to move the curtain between its open position and its position closing during movement of the chain 16.
  • the chain 16 can be fixed to the upper end of the side edges 2 and be also guided in the guideways 18, so to be able to push on this end, in the axis of these edges 2, to bring the curtain into its position closing.
  • Figures 17 and 18 show a fourth embodiment of a closure device according to the invention which differs from previous embodiments by nature of paths straight guide 3 and the rigid members 5.
  • the rigid members are formed by clips, preferably metallic, having the shape of a U whose free ends of the two wings 10 and 11 form outwardly curved portions 10a and 11a which, as shown in Figure 17, are housed in an inner recess 56 located near the outer edge of the roads guidance 3.
  • these organs 5 have, between these curved parts 10a and 11a and their projecting end 6 tight around the bead 7 of the curtain, part stamped 57 serving as support for the various organs 5 one against the other on the side edges 2 of the curtain, inside the guideways 3.
  • Figures 19, 20 and 21 relate to a fifth embodiment of the invention particularly interesting, which stands out basically compared to the embodiments previous by the fact that the rigid members 5, fixed at the lateral edges 2 of the curtain 1, cooperate between them by via a ball joint 28.
  • this ball joint coupling includes a housing spherical 29 at one end of the rigid member 5 and a ball head pivot 30 at the opposite end of this rigid member 5.

  • both the housing 29 and the pivot 30 are split in the longitudinal direction of edges 2.
  • the pivot 30 is slightly compressed then that the housing can undergo a certain expansion, so as to thus ensure a reliable fixing of two organs rigid successive with respect to each other, while allowing an articulation of these following all directions.
  • the nature of this compression and this expansion is of course a function of the materials of which constituted the organ 5.
  • the rigid members 5 extend as well with their pivot 30 as with their corresponding housing 29 around the bead 7, as illustrated clearly in Figure 20.
  • Figures 22 and 23 relate to a sixth embodiment of the closure device, according to the invention, which is essentially distinguished by compared to the previous embodiment by the fact that each rigid member 5 is provided with two rollers 26 thus considerably reducing friction side edges 2 when moving in the guideways 3.
  • Figures 24 to 26 relate to a seventh embodiment of the invention of a relatively simple execution with regard to the fixing the rigid members to the lateral edges 2 of the curtain.
  • This embodiment stands out basically compared to the embodiments previous by the fact that no particular finish is provided at the side edges 2. For example, contrary to what is the case in practically all the previous embodiments, a bead is not therefore not planned.
  • the rigid members 5 with ball joint 28 are formed of two wings 10 and 11 articulated to each other in 59. As clearly illustrated by Figures 25 and 26 these two wings are rigidly fixed on either side of the side edges 2 of the curtain.

  • These are housings analogous to those provided in the embodiment shown in Figures 19-21.
  • Figures 30 to 32 relate to a ninth embodiment of the closure device according to the invention.
  • This embodiment stands out basically compared to previous forms of realization by the fact that one makes use of a curtain 1 whose side edges 2 are not necessarily incompressible in themselves following their direction longitudinal but were rendered indirectly incompressible by the presence of a stiffening zone 1 'which extends near these lateral edges 2, in outside the guideways 3.
  • lateral edge rendered incompressible designates any type of lateral edge which, combined with a stiffening zone, located either in outside the guideways either inside these last, avoids that when a push is exerted on this edge or on this stiffening zone 1 ' in the closing direction of the curtain, this edge can be deform by jamming in these guide paths or by creating exaggerated friction forces which would harm to the proper functioning of the entire device closing.
  • the aforementioned stiffening zone 1 ' is formed by a toothed belt fixed to the curtain 1, while the drive means include a pulley notched 4 rotating around a 4 'axis and meshing with the toothed belt 1 '.

  • the improvement consists in interposing, in the access passage 49, between the two separate fixed portions 3a and 3b of the guide extending in the extension of each other a movable guide fitting 58, which is hinged at its edge upper, through hinges 64, to the portion 3a of the guide tracks 3, so that switch between a first position, in which this fitting 58 extends in the extension of portions 3a and 3b of the guide tracks, as shown in FIG. 33, and a second position, in which it is oriented by its lower opening outside the guideways 3, as shown in Figure 35.
  • a spring 65 makes it possible to maintain or return the fitting to said first position.
  • An interesting variant of the device according to the invention consists in providing, as means to avoid edge compression side 2 of curtain 1 in the direction of their length at least when moving the latter towards its closed position, a drive mechanism for example comprising a cable and pulleys applying traction on these side edges to cause the curtain to close.
  • a drive mechanism for example comprising a cable and pulleys applying traction on these side edges to cause the curtain to close.

  • the curtain is stretched between the guide tracks 3, in which move these edges, at least when it's in its closed position.
  • the curtain is preferably fully flexible, without no transverse stiffening element.
  • the side edges 2 of the curtain 1 could be made substantially incompressible in the direction of their length by predicting, near these edges, a succession of rigid plates fixed to the curtain and located outside the guideways or by fixing against curtain 1 a strip of reinforced fabric following the direction of movement of the curtain thus allowing to avoid that in this area and therefore also in the place from the side edges the curtain may gather when a pushing force is exerted, in the closing direction of the curtain, either directly on the side edges or on this armed band.
  • the side edges could simply consist of the bead 7, for example.
  • edges side could be made noticeably incompressible in the sense of their length in introducing into it a succession of balls some not very similar to the balls 62 of the embodiment shown in Figures 27 to 29. Where appropriate, these balls could be introduced into the hollow pipe 8, which would form a sheath for the balls and which, in this case, would have a section somewhat larger than that of embodiments shown in the accompanying figures.
  • plan small rigid blocks which would for example be molded on the side edges of the curtain, for example like the teeth of a zipper, between which would provided a flexible, but non-compressible seal.
  • this tree can be formed by two coaxial sections near the side edges of the curtain for driving the telescopic arm 19. Also, if we makes use of other training means 4, not requiring not such a tree 20, as it is for example the case in the embodiments shown in Figures 14 to 16, such a tree could be omitted.
  • the curtain does not necessarily have to roll up but can for example move in a plane any incline, horizontal or vertical from its position closing to its open position.

PCT No. PCT/BE95/00038 Sec. 371 Date Jan. 3, 1997 Sec. 102(e) Date Jan. 3, 1997 PCT Filed Apr. 20, 1995 PCT Pub. No. WO95/30064 PCT Pub. Date Nov. 9, 1995According to the invention, the lateral edges of the screen are substantially incompressible or rendered incompressible in their lengthwise direction. A driving device is provided making it possible to apply a thrust force to these edges in the longitudinal direction of the edges in their guide channels in order to move the screen towards its closed position and towards its open position. The screen is provided, near or on the lateral edges mentioned above, with a series of members which are substantially rigid in the longitudinal direction of these edges. These members are able to bear against one another in the direction of the lateral edges, and are preferably able to be articulated with respect to each other such as to allow the rolling up or flexion of the screen in its open position.

Description

La présente invention est relative à un dispositif de fermeture comprenant un rideau souple, telle qu'une bâche, dont les bords latéraux sont guidés dans des chemins de guidage permettant ainsi de déplacer le rideau entre une position de fermeture et une position d'ouverture.The present invention relates to a closing device comprising a flexible curtain, such as that a tarpaulin, the lateral edges of which are guided in guide paths allowing the curtain to be moved between a closed position and a position opening.

Dans un premier type des dispositifs de fermeture de ce genre connus jusqu'à présent à rideau souple, le bord inférieur de ce dernier est pourvu d'une barre de lestage s'étendant sur toute la largeur du rideau pour permettre la fermeture de ce dernier essentiellement sous le poids de cette barre de lestage et maintenir celui-ci dans un état tendu.In a first type of devices closing like this known so far curtain flexible, the lower edge of the latter is provided with a ballast bar extending over the entire width of the curtain to allow the closure of the latter essentially under the weight of this ballast bar and maintain it in a tense state.

La présence d'une telle barre de lestage a divers inconvénients non négligeables. Ainsi, par suite de son inertie, les vitesses d'ouverture et de fermeture sont limitées et des précautions particulières doivent être prises pour le freinage du mouvement de montée et de descente du rideau suffisamment de temps avant l'arrêt de ce dernier. De plus, le poids d'une telle barre de lestage nécessite une énergie relativement importante pour amener le rideau dans sa position d'ouverture. Enfin, des moyens de sécurité fiables doivent être prévus dans le circuit de commande du rideau pour éviter des accidents lorsqu'une personne ou un objet quelconque se trouve en-dessous du rideau lors de sa descente vers sa position de fermeture.The presence of such a ballast bar has various significant disadvantages. So, as a result of its inertia, the opening and closing speeds are limited and special precautions should be sockets for braking the upward movement and lowering the curtain sufficient time before stopping this last. In addition, the weight of such a ballast bar requires relatively large energy to bring the curtain in its open position. Finally, means reliable safety devices must be provided in the curtain control to prevent accidents when a anyone or any object is below the curtain when it descends to its closed position.

Dans un autre type des dispositifs de fermeture connus du genre précité, on prévoit des moyens d'entraínement qui, par l'intermédiaire de poulies de renvoi, tirent sur les bords latéraux du rideau pour amener ce dernier dans sa position de fermeture. Quoique dans un tel type de dispositif de fermeture, il ne soit théoriquement pas indispensable de prévoir une barre de lestage et de raidissement au bord inférieur du rideau, du point de vue pratique, toutefois, une telle barre de raidissement et de lestage est généralement nécessaire pour assurer le bon fonctionnement de la fermeture.In another type of devices known closure of the aforementioned genre, means are provided which, via pulleys of return, pull on the side edges of the curtain to bring the latter in its closed position. Albeit in one this type of closing device, it is not theoretically not essential to provide a bar of ballasting and stiffening at the lower edge of the curtain, practical point of view, however, such a bar of stiffening and ballasting is usually required to ensure the proper functioning of the closure.

Le document US-A-3 092 170 décrit une porte qui effectue un mouvement horizontal et qui est suspendue dans un rail de guidage supérieur. Cette porte est équipée de barres verticales, entraínées par une chaíne, sur lesquelles un rideau est suspendu.Document US-A-3,092,170 describes a door that moves horizontally and is suspended in an upper guide rail. This door is equipped with vertical bars, driven by a chain, on which a curtain is suspended.

Le document FR-A-2 683 258 est relative à une porte avec un rideau pouvant se déplacer suivant une direction verticale. Le rideau de cette porte présente des bords latéraux constitués de feuilles souples et élastiques afin d'améliorer l'étanchéité de cette porte.Document FR-A-2 683 258 relates to a door with a curtain that can move along a vertical direction. The curtain of this door has side edges made of flexible and elastic sheets to improve the tightness of this door.

Dans le document DE-A-2 736 936 un store à lamelles non souples est décrit. Une chaíne attachée au bord inférieur du store permet de bloquer le store vis-à-vis d'un soulèvement non souhaité. Pour la fermeture du store, un arbre d'entraínement tourne autour de son axe afin de dérouler le store par gravité.In document DE-A-2 736 936 a blind with non-flexible lamellae is described. A chain attached to the lower edge of the blind allows to block the blind vis-à-vis unwanted uplift. For closing the blind, a drive shaft rotates around its axis to unwind the blind by gravity.

Un des buts essentiels de la présente invention est de proposer un dispositif de fermeture d'un rideau souple qui ne nécessite plus une barre de raidissement et de lestage.One of the essential purposes of this invention is to provide a device for closing a flexible curtain that no longer requires a bar stiffening and ballasting.

A cet effet, suivant, l'invention, les bords latéraux du rideau sont sensiblement incompressibles ou rendus incompressibles dans le sens de leurs longueur, des moyens d'entraínement étant prévus permettant de provoquer une force de poussée sur ces bords suivant la direction longitudinale de ces derniers dans leurs chemins de guidage pour déplacer le rideau vers sa position de fermeture et de éventuellement vers sa position d'ouverture.To this end, according to the invention, the side edges of the curtain are substantially incompressible or made incompressible along their length, drive means being provided allowing to cause a pushing force on these edges according to the longitudinal direction of these in their paths guide to move the curtain to its position closing and possibly back to its position opening.

Avantageusement, le rideau est pourvu, aux ou à proximité des bords latéraux précités, d'une succession d'organes sensiblement rigides suivant la direction longitudinale de ces bords latéraux, ces organes pouvant s'appuyer les uns contre les autres suivant la direction de ces bords latéraux, et pouvant de préférence être articulés les uns par rapport aux autres de manière à permettre l'enroulement ou la flexion du rideau dans sa position d'ouverture.Advantageously, the curtain is provided, at or near the aforementioned side edges, of a succession of substantially rigid organs according to the longitudinal direction of these lateral edges, these organs can lean against each other according to the direction of these lateral edges, and preferably being able be articulated with each other so as to allow the curtain to roll up or bend in its open position.

Suivant une forme de réalisation particulière de l'invention, les organes rigides entourent les bords latéraux du rideau en formant une saillie par rapport à la surface de ce dernier, cette saillie étant maintenue dans les chemins de guidage précités et se déplaçant dans ces derniers.According to an embodiment particular of the invention, the rigid members surround the side edges of the curtain, projecting from relative to the surface of the latter, this projection being maintained in the aforementioned guideways and is moving into these.

Suivant une forme de réalisation préférentielle de l'invention, le rideau présente, à proximité d'au moins un de ses bords latéraux et à l'extérieur des chemins de guidage précités, des moyens de raidissement permettant de rendre les bords susdits sensiblement incompressibles dans le sens de leur longueur, ces moyens de raidissement étant avantageusement formés par une courroie crantée solidaire du rideau et s'étendant le long d'au moins un des bords latéraux de ce dernier, des moyens d'entraínement précités coopérant avec ladite courroie crantée.According to an embodiment preferential of the invention, the curtain has, at proximity of at least one of its lateral edges and outside the aforementioned guideways, means for stiffening to make the above edges substantially incompressible in the direction of their length, these stiffening means being advantageously formed by a toothed belt integral with the curtain and extending the along at least one of the lateral edges of the latter, aforementioned drive means cooperating with said toothed belt.

    Le dispositif de fermeture suivant l'invention et dont quelques formes de réalisation particulières ont été représentées aux figures annexées comprend un rideau souple 1 dont les bords latéraux 2 sont guidés dans des chemins de guidage 3 pour permettre au rideau 1 de se déplacer entre une position de fermeture et une position d'ouverture. Ces bords sont de préférence saillants par rapport au plan du rideau de manière à permettre de les maintenir aisément dans les chemins de guidage.The following closing device the invention and including some embodiments particular have been shown in the accompanying figures comprises a flexible curtain 1, the lateral edges 2 of which are guided in guideways 3 to allow the curtain 1 to move between a closed position and an open position. These edges are preferably protruding from the plane of the curtain so as to allow them to be easily maintained in the paths of guide.

    Par l'expression "rideau souple", il y a lieu de comprendre, dans le cadre de la présente invention, tout élément plan pouvant former une fermeture ou une séparation et pouvant s'enrouler autour d'un axe ou se plier, telle qu'une bâche, une bande en matière plastique, etc..., destiné à la fermeture d'une baie, à la réalisation d'une cloison de séparation, à couverture, d'une piscine ou la réalisation d'un auvent. A cet égard, il y a lieu de noter que, suivant l'invention, une préférence prononcée est donnée aux portes étanches comprenant donc un rideau qui se déplace entre deux chemins de guidage verticaux.By the expression "flexible curtain", there is instead of understanding, in the context of the present invention, any planar element which may form a closure or a separation and can wrap around an axis or fold, such as a tarp, a plastic strip, etc ..., intended for the closure of a bay, for the realization a partition wall, roof, swimming pool or the realization of an awning. In this regard, there is reason to note that, according to the invention, a pronounced preference is given to watertight doors therefore comprising a curtain which moves between two vertical guide paths.

    D'une façon générale, le dispositif de fermeture, suivant l'invention, est caractérisé par le fait que les bords latéraux 2 du rideau 1 sont sensiblement incompressibles ou rendus incompressibles dans le sens de leur longueur, de manière à permettre d'appliquer sur ces bords une poussée suivant leur sens longitudinal dans les chemins de guidage 3 sans qu'ils puissent former des fronces qui sont de nature à bloquer ces bords dans ces chemins de guidage. Ainsi, des moyens d'entraínement 4 sont également prévus permettant d'agir sur ces bords 2 dans leurs chemins de guidage 3 pour amener le rideau 1 dans sa position de fermeture et éventuellement dans sa position d'ouverture.Generally speaking, the closure, according to the invention, is characterized by the fact that the side edges 2 of the curtain 1 are substantially incompressible or made incompressible in the sense of their length, so as to allow to apply on these edges a longitudinal thrust in the guideways 3 without them being able to form gathers that are likely to block these edges in these guide paths. Thus, training means 4 are also provided for acting on these edges 2 in their guideways 3 to bring the curtain 1 in its closed position and possibly in its open position.

    Suivant l'invention les moyens d'entraínement 4 sont agencés de manière à permettre de créer une force de poussée sur les bords latéraux 2 du rideau 1 suivant la direction longitudinale de ces derniers, provoquant ainsi le déplacement du rideau vers sa position de fermeture, tel que représenté à la figure 1.According to the invention the means 4 are arranged to allow create a pushing force on the side edges 2 of the curtain 1 in the longitudinal direction of these last, causing the curtain to move towards its closed position, as shown in Figure 1.

    Dans la forme de réalisation illustrée à la figure 1, l'ouverture du rideau 1 est provoquée par un ressort 31 fixé entre l'extrémité libre d'une courroie 32 et un point fixe à la base 33. Lors de la fermeture du rideau 1, cette courroie 32 s'enroule sur une poulie 34 calée sur un arbre d'entraínement 20 qui est actionné par un moteur-réducteur 36, ce dernier étant commandé à partir d'une boíte de contrôle 37. De cette façon, le ressort 31 est amené dans un état tendu lorsque le rideau 1 est dans sa position de fermeture, comme montré à la figure 1. Ceci permet ainsi l'enroulement automatique du rideau vers sa position d'ouverture lorsqu'il est débloqué dans cette position de fermeture.In the embodiment illustrated in Figure 1, the opening of the curtain 1 is caused by a spring 31 fixed between the free end of a belt 32 and a fixed point at base 33. When closing the curtain 1, this belt 32 is wound on a pulley 34 wedged on a drive shaft 20 which is actuated by a gear motor 36, the latter being controlled from a control box 37. In this way, the spring 31 is brought into a stretched state when curtain 1 is in its closed position, as shown in figure 1. This thus allows the automatic winding of the curtain towards its open position when unlocked in this closed position.

    Dans cette forme de réalisation particulière, le rideau 1 est formé d'une bâche dans laquelle sont agencées trois fenêtres 38 réalisées en une matière plastique transparente et qui est enroulée dans sa position d'ouverture dans un caisson de section carrée 39 fermé à ses deux extrémités par des flasques 40.In this embodiment particular, the curtain 1 is formed of a tarpaulin in which are arranged three windows 38 made in one transparent plastic material which is rolled up in its open position in a square section box 39 closed at both ends by flanges 40.

    Ces deux flasques 40 présentent, dans leurs faces intérieures dirigées l'une vers l'autre, des chemins de guidage en spirale 18, comme montré en détail aux figures 4 et 5.These two flanges 40 have, in their interior faces facing each other, spiral guideways 18, as shown in detail in Figures 4 and 5.

    Comme illustré par la figure 4, ces chemins de guidage en spirale 18 s'étendent dans le prolongement des chemins de guidage rectilignes 3.As illustrated in Figure 4, these spiral guideways 18 extend into the extension of straight guideways 3.

    Dans la première forme de réalisation du dispositif de fermeture suivant l'invention, montrée plus particulièrement aux figures 4 à 13, le rideau 1 est pourvu, à ses bords latéraux 2, d'une succession d'organes saillants 5 qui sont au moins rigides suivant la direction longitudinale de ces bords latéraux 2. Ces organes 5 s'appuient les uns contre les autres suivant cette direction longitudinale et sont articulés les uns par rapport aux autres, de manière à permettre l'enroulement du rideau 1 à l'intérieur du caisson 39, lorsqu'il est amené dans sa position d'ouverture.In the first embodiment of the closure device according to the invention, shown more particularly in Figures 4 to 13, the curtain 1 is provided, at its lateral edges 2, with a succession of members projections 5 which are at least rigid in the direction longitudinal of these lateral edges 2. These organs 5 lean against each other following this longitudinal direction and are hinged together by relation to others, so as to allow the winding of the curtain 1 inside the box 39, when it is brought in its open position.

    Comme surtout montré par les figures 8 à 13, ces organes rigides 5 entourent les bords latéraux 2 du rideau 1 en formant une saillie 6 de part et d'autre par rapport au plan de ce dernier et coulissent avec un certain frottement dans les chemins de guidage 3 et 18, afin d'éviter que le rideau puisse se déplacer entre la position d'ouverture et de fermeture sous son propre poids. Ceci a comme avantage qu'il n'est pas nécessaire de prévoir des moyens de freinage particuliers aux fins de course du rideau.As especially shown in Figures 8 to 13, these rigid members 5 surround the lateral edges 2 of the curtain 1 by forming a projection 6 on either side by compared to the plan of the latter and slide with a certain friction in guideways 3 and 18, so to prevent the curtain from moving between the position opening and closing under its own weight. This has as an advantage that it is not necessary to provide special braking means for the limit switches of the curtain.

    Toujours dans cette même forme de réalisation, les bords latéraux 2 du rideau 1 présentent un bourrelet sensiblement continu 7 autour duquel sont fixés les organes rigides 5.Always in this same form of embodiment, the side edges 2 of the curtain 1 have a substantially continuous bead 7 around which are fixed rigid bodies 5.

    Avantageusement, ce bourrelet comprend une conduite creuse 8 pouvant par exemple contenir un fluide ou un conducteur de courant électrique.Advantageously, this bead comprises a hollow pipe 8 which can for example contain a fluid or conductor of electric current.

    Dans la forme de réalisation illustrée par les figures 6 à 13, cette conduite contient un gaz, tel que de l'air 41, d'un système de sécurité pneumatique quelconque non illustré. Une telle conduite 8 est donc parfaitement protégée aussi bien par les organes rigides 5 que par les chemins de guidage 3 dans lesquels ces organes se déplacent.In the illustrated embodiment in FIGS. 6 to 13, this pipe contains a gas, such air 41, a pneumatic safety system any not shown. Such conduct 8 is therefore perfectly protected as well by rigid bodies 5 only by the guideways 3 in which these members are moving.

    Dans la première forme de réalisation spécifique illustrée notamment aux figures 6 à 13, les organes rigides 5 ont l'allure de manchons saillants 6 présentant dans leur paroi une fente longitudinale 9 par laquelle le rideau 1 sort des manchons en définissant ainsi deux ailes 10 et 11 s'étendant de part et d'autre de ce dernier. L'aile 10 présente une longueur dans la direction des bords latéraux 2 du rideau inférieure à celle de l'autre aile 11, de manière à ce qu'un évidement 12 soit formé d'un côté du rideau 1 entre deux organes consécutives 5 permettant ainsi la flexion du bord 2 transversalement au plan du rideau du côté susdit (voir figure 9). Les autres ailes 11 de ces organes 5 s'appuyant bout à bout les unes contre les autres dans le sens longitudinal des bords latéraux 2 du rideau 1 (voir figure 8).In the first embodiment specific illustrated in particular in FIGS. 6 to 13, the rigid members 5 have the appearance of protruding sleeves 6 having in their wall a longitudinal slot 9 by which the curtain 1 comes out of the sleeves thus defining two wings 10 and 11 extending on either side of this latest. Wing 10 has a length in the direction side edges 2 of the curtain lower than that of the other wing 11, so that a recess 12 is formed on one side of the curtain 1 between two consecutive members 5 thus allowing the bending of the edge 2 transversely to the plan of the curtain on the above side (see Figure 9). Others wings 11 of these members 5 bearing end to end against the others in the longitudinal direction of the edges side 2 of curtain 1 (see Figure 8).

    Plus particulièrement, dans cette forme de réalisation, l'aile la plus courte 10 de l'organe rigide 5 présente une longueur égale à la moitié de celle de l'autre aile 11 et se situe symmétriquement par rapport à cette autre aile 11, de manière à former ainsi en regard de cette dernière et de part et d'autre de l'aile la plus courte 10 un évidement 12 présentant la longueur d'un quart de celle de l'aile 11.More specifically, in this form embodiment, the shortest wing 10 of the rigid member 5 has a length equal to half that of the other wing 11 and is symmetrically relative to this other wing 11, so as to thus form opposite the latter and on either side of the most short 10 a recess 12 having the length of a quarter that of wing 11.

    La figure 7 illustre, d'une façon schématique, le comportement de ces organes rigides spécifiques 5 lors de l'enroulement du rideau. On constate que les bords latéraux enroulés peuvent se froncer librement dans les évidements 12 facilitant ainsi la flexion de ces derniers.Figure 7 illustrates, in a way schematic, the behavior of these rigid organs specific 5 when rolling up the curtain. We aknowledge that the rolled side edges can gather freely in the recesses 12 thus facilitating the bending of these.

    Le fait que l'aile 10, située du côté du centre de courbure du chemin de guidage en spirale 19 est plus courte que l'aile opposée 11 des organes rigides 5 permet, de plus, d'éviter le déplacement de ces organes 5 sur les bords latéraux 2 du rideau 1 lors de l'enroulement de ce dernier dans sa position d'ouverture. En effet, comme illustré clairement par la figure 7, deux organes rigides consécutifs s'articulent suivant l'axe neutre des bords latéraux 2 tout en restant en contact les uns contre les autres à l'endroit 11' situé sur cet axe neutre.The fact that wing 10, located on the side of the center of curvature of spiral guideway 19 east shorter than the opposite wing 11 of the rigid members 5 also makes it possible to avoid the displacement of these organs 5 on the side edges 2 of the curtain 1 during winding of the latter in its open position. Indeed, as clearly illustrated in Figure 7, two organs rigid lines are articulated along the neutral axis of side edges 2 while remaining in contact with each other the others at location 11 'located on this neutral axis.

    Comme on peut le remarquer aux figures 6, 10 et 11 les manchons 6 présentent une section rectangulaire et sont montés avec un certain jeu transversal par rapport au rideau 1 dans les chemins de guidage en spirale 18. Ainsi, une certaine translation des bords 2 du rideau est possible dans le plan des flasques 40.As can be seen in Figures 6, 10 and 11 the sleeves 6 have a section rectangular and are mounted with some play transverse to curtain 1 in the paths of spiral guidance 18. Thus, a certain translation of the edges 2 of the curtain is possible in the plane of the flanges 40.

    Par ailleurs, par suite de la forme rectangulaire de la section de la saillie 6 et de la forme correspondante de l'intérieur des chemins de guidage 18 le déplacement angulaire des organes rigides 5 dans ces chemins de guidage est très réduit et comporte de tout au plus 10° autour de l'axe central 25 de ces derniers.Furthermore, because of the shape rectangular of the section of the projection 6 and of the shape inside the guideways 18 the angular displacement of the rigid members 5 in these guide paths is very small and involves everything plus 10 ° around the central axis 25 of these.

    De plus, la distance radiale entre les spires des chemins de guidage 18 est telle que, dans la position enroulée, les couches superposées du rideau enroulé ne se touchent pas, comme montré clairement aux figures 4 à 7. De plus, il peut être important de tendre le rideau 1 entre les flasques 4. Ceci a comme avantage important que l'on évite que les fenêtres 38 peuvent se griffer lors de l'enroulement du rideau.In addition, the radial distance between the turns of the guideways 18 is such that in the rolled up position, the layers of the curtain coiled do not touch, as shown clearly to Figures 4 to 7. In addition, it may be important to stretch curtain 1 between the flanges 4. This has the advantage important to avoid that windows 38 can get scratch when rolling up the curtain.

    Les chemins de guidage en spirale 18 délimitent un canal sensiblement tubulaire 22, de préférence de section polygonale, présentant dans sa paroi 23, du côté du rideau 1, une fente longitudinale 24 pour le passage de ce dernier.Spiral guideways 18 delimit a substantially tubular channel 22, of preference of polygonal section, having in its wall 23, on the side of the curtain 1, a longitudinal slot 24 for the passage of the latter.

    L'axe central en spirale 25 de ce canal 22 étant situé dans le plan de symmétrie de la fente 24, tandis que le rideau s'étend suivant le plan 27.The central spiral axis 25 of this channel 22 being located in the plane of symmetry of the slot 24, while the curtain extends along plane 27.

    La figure 10 montre la position des organes rigides 5 dans les chemins de guidage 18 lors du déroulement du rideau vers sa position de fermeture. Le centre de courbure, qui est situé sur l'axe 17 se trouve dans ce cas du côté droit de la figure 10. Ainsi, les bords latéraux 2 du rideau 1 sont appliqués contre la face extérieure des chemins de guidage par rapport à ce centre de courbure.Figure 10 shows the position of the rigid members 5 in the guideways 18 during unwinding of the curtain towards its closed position. The center of curvature, which is located on axis 17 is located in this case on the right side of figure 10. Thus, the side edges 2 of curtain 1 are applied against the face outside of the guideways with respect to this center curvature.

    Par contre, lors de l'enroulement du rideau 1, les organes rigides 5 subiront un déplacement en sens inverse, comme représenté à la figure 10. Dans ce cas, les bords latéraux 2 du rideau 1 sont donc appliqués contre la face intérieure des chemins de guidage 18, du côté du centre de courbure précité.On the other hand, during the winding of the curtain 1, the rigid members 5 will undergo a displacement in reverse, as shown in Figure 10. In this case, the side edges 2 of the curtain 1 are therefore applied against the inner face of the guideways 18, of the side of the aforementioned center of curvature.

    Ces différentes dispositions pour les organes rigides 5 permettent d'éviter que ces derniers se déplacent sur les bords latéraux 2 du rideau 1 lors de son enroulement et déroulement.These different provisions for rigid members 5 make it possible to prevent the latter from move on the side edges 2 of the curtain 1 when it winding and unwinding.

    Comme illustré par les figures 4 et 5, lorsque, dans la position d'ouverture, le rideau est enroulé en spirale, les moyens d'entraínement 4 comprennent à proximité des flasques 40, à l'intérieur du caisson 39, un bras télescopique 19 coopérant avec l'extrémité supérieur des bords latéraux du rideau 1.As shown in Figures 4 and 5, when, in the open position, the curtain is wound in a spiral, the drive means 4 comprise near the flanges 40, inside the box 39, a telescopic arm 19 cooperating with the end upper side edges of curtain 1.

    Ce bras télescopique 19 est monté transversalement sur un arbre d'entraínement 20 s'étendant suivant l'axe précité 17 et est fixé à une barre 21 parallèle à cet arbre 20. Cette barre coopère avec l'extrémité des bords latéraux 2 du rideau, qui sont engagés dans les chemins de guidage en spirale 18 par l'intermédiaire d'une pièce de liaison 35, d'une part, fixée au bord transversal 41 du rideau 1 et, d'autre part, coulissant dans une rainure longitudinale 42 de cette barre 21.This telescopic arm 19 is mounted transversely on a drive shaft 20 extending along the aforementioned axis 17 and is fixed to a bar 21 parallel to this shaft 20. This bar cooperates with the end of the side edges 2 of the curtain, which are engaged in the spiral guideways 18 by through a connecting piece 35, on the one hand, fixed to the transverse edge 41 of the curtain 1 and, on the other hand, sliding in a longitudinal groove 42 of this bar 21.

    Plus particulièrement, le bras télescopique 19 comprend deux pièces de guidage en U parallèles 43, fixées de part et d'autre sur l'arbre 20, dans lesquelles sont montées à coulissement des tubes de section carrée 43 dont une des extrémités est rendue solidaire à la barre 21, qui est également formée d'un tube carré.More specifically, the telescopic arm 19 includes two U-shaped guide pieces parallel 43, fixed on either side on the shaft 20, in which sliding tubes are mounted square section 43 one end of which is rendered integral with the bar 21, which is also formed of a tube square.

    Ainsi, pour déplacer le rideau 1 dans le sens de la flèche 45, c'est-à-dire pour amener le rideau dans sa position de fermeture, l'arbre 20 est mis en rotation dans le sens de la flèche 46 par le moteur 36 et la pièce intermédiaire 35 pousse sur le bord latéral 2 dans le sens de sa longueur, tandis que la barre 44 subit un déplacement dans le sens de la flèche 47. Au cas de besoin, la pièce de liaison 35 peut coulisser dans la rainure 42 de la barre 21 lors du déroulement du rideau.So, to move curtain 1 in the direction of arrow 45, i.e. to bring the curtain in its closed position, the shaft 20 is brought into rotation in the direction of arrow 46 by the motor 36 and the intermediate piece 35 pushes on the lateral edge 2 in the direction of its length, while the bar 44 undergoes a move in the direction of arrow 47. In case of if necessary, the connecting piece 35 can slide in the groove 42 of the bar 21 during the unwinding of the curtain.

    L'ouverture du rideau peut être provoquée soit par le ressort 31, comme déjà décrit ci-dessus, soit en entraínant l'arbre 20 dans le sens opposé à la flèche 46.The curtain may open either by the spring 31, as already described above, or by driving the shaft 20 in the opposite direction to the arrow 46.

    Avantageusement, comme montré plus en détail aux figures 12 et 13, les chemins de guidages rectilignes 3 comprennent un profilé en U 48 réalisé en une matière semi-élastique, de manière à permettre, lorsqu'une force de traction est exercée sur le rideau 1 dans le sens de la flèche F dépassant une certaine limite, de dégager les bords latéraux 2 du rideau des chemins de guidage 3. Une telle force pourrait par exemple résulter du fait qu'un véhicule accroche le rideau 1 au moment où celui-ci est encore dans sa position de fermeture. Advantageously, as shown more in detail in Figures 12 and 13, the guideways rectilinear 3 comprise a U-shaped profile 48 made in a semi-elastic material, so as to allow, when a pulling force is exerted on the curtain 1 in the direction arrow F exceeding a certain limit, to clear the lateral edges 2 of the curtain of the guide tracks 3. Such force could for example result from the fact that a vehicle hangs curtain 1 when it is still in its closed position.

    Grâce au passage d'accès 49, que présentent chacun de ces chemins de guidage à l'entrée du caisson 39, lorsqu'un bord latéral 2 s'est dégagé de son chemin de guidage 3, comme illustré par la figure 13, lors du déplacement du rideau dans le sens opposé à la flèche 45, ce bord se réengagera automatiquement par ce passage d'accès 49 dans son chemin de guidage, à l'entrée du caisson 39 (voir figure 4).Thanks to access passage 49, that have each of these guide paths at the entrance to the box 39, when a lateral edge 2 has cleared of its guide path 3, as illustrated in FIG. 13, when moving the curtain in the opposite direction to the arrow 45, this edge will automatically reengage by this passage access 49 in its guide path, at the entrance to the box 39 (see Figure 4).

    De telles mesures technologiques ont fait l'objet du brevet européen 272.733.Such technological measures have made the subject of European patent 272,733.

    La base du profilé en U 48 est maintenue dans un support métallique 50 présentant également une section de forme en U.The base of the U-shaped profile 48 is maintained in a metal support 50 also having a U-shaped section.

    Ces supports 50 sont avantageusement montés sur des éléments élastiques non représentés. Un tel système de montage a fait l'objet de la demande de brevet européen n° 92909384 du même déposant.These supports 50 are advantageously mounted on elastic elements not shown. Such mounting system was the subject of the patent application n ° 92909384 by the same applicant.

    Les figures 14 et 15 montrent très schématiquement une deuxième forme de réalisation du dispositif de fermeture suivant l'invention.Figures 14 and 15 show very schematically a second embodiment of the closing device according to the invention.

    Dans cette forme de réalisation les bords latéraux 2 présentent l'allure d'une chaíne à articulation se déplaçant dans les chemins de guidage 3.In this embodiment the edges side 2 have the look of a hinged chain moving in the guideways 3.

    Le chemin de guidage rectiligne 3 est interrompu avant l'entrée dans le caisson 40 et, à cet endroit d'interruption, de part et d'autre du bord latéral 2, sont prévus les moyens d'entraínement 4. Ces moyens d'entraínement comprennent deux paires de roues dentées 51 sur lesquelles se déplace une bande sans fin 52 munie extérieurement de dents pouvant s'engager dans les maillons de la chaíne à articulation 15.The straight guide path 3 is interrupted before entering the box 40 and, at this place of interruption, on either side of the lateral edge 2, are provided the drive means 4. These means drive include two pairs of gears 51 on which moves an endless belt 52 provided externally of teeth capable of engaging in the links of the articulation chain 15.

    Pour la clarté, sur la figure 15 ont uniquement été représentés les axes de rotation 55 des roues dentées 51.For clarity, in Figure 15 have only the axes of rotation 55 of the cogwheels 51.

    Une autre différence de cette deuxième forme de réalisation par rapport à la première est que, dans le caisson 39, le rideau est replié en zig-zag lorsqu'il est amené dans sa position d'ouverture.Another difference from this second embodiment compared to the first is that, in box 39, the curtain is folded in a zig-zag when brought into its open position.

    La figure 16 est une représentation simplifiée d'une troisième forme de réalisation du dispositif de fermeture suivant l'invention.Figure 16 is a representation simplified of a third embodiment of the closing device according to the invention.

    Dans cette forme de réalisation, le rideau 1 est amené dans une position d'ouverture horizontale, en étant guidé le long d'un plafond 53 dans des chemins de guidage 18, après avoir subi une déviation de 90°. Par ailleurs, les moyens d'entraínement 4 comprennent une transmission à chaíne sans fin 16 pouvant se déplacer le long de la partie horizontale des chemins de guidage 18 suivant un mouvement de va-et-vient, comme indiqué par les flèches 54. Une pièce de liaison 35 est prévue entre l'extrémité supérieure des bords latéraux 2 du rideau et la chaíne 16 permettant donc de déplacer le rideau entre sa position d'ouverture et sa position de fermeture lors du mouvement de la chaíne 16.In this embodiment, the curtain 1 is brought into an open position horizontal, being guided along a ceiling 53 in guide tracks 18, after having undergone a deviation 90 °. In addition, the drive means 4 include an endless chain transmission 16 capable of move along the horizontal part of the paths guide 18 in a back-and-forth movement, as indicated by the arrows 54. A connecting piece 35 is provided between the upper end of the side edges 2 of the curtain and chain 16 therefore allowing to move the curtain between its open position and its position closing during movement of the chain 16.

    Dans une variante intéressante de cette forme de réalisation, la chaíne 16 peut être fixée à l'extrémité supérieure des bords latéraux 2 et être également guidée dans les chemins de guidage 18, de manière à pouvoir ainsi pousser sur cette extrémité, dans l'axe de ces bords 2, pour amener le rideau dans sa position de fermeture.In an interesting variant of this embodiment, the chain 16 can be fixed to the upper end of the side edges 2 and be also guided in the guideways 18, so to be able to push on this end, in the axis of these edges 2, to bring the curtain into its position closing.

    Les figures 17 et 18 montrent une quatrième forme de réalisation d'un dispositif de fermeture suivant l'invention qui se différencie par rapport aux précédentes formes de réalisation par la nature des chemins de guidage rectilignes 3 et les organes rigides 5.Figures 17 and 18 show a fourth embodiment of a closure device according to the invention which differs from previous embodiments by nature of paths straight guide 3 and the rigid members 5.

    Dans cette quatrième forme de réalisation les organes rigides sont formés par des clips, de préférence métalliques, présentant l'allure d'un U dont les extrémités libres des deux ailes 10 et 11 forment des parties courbées vers l'extérieur 10a et 11a qui, comme montré à la figure 17, sont logées dans un creux intérieur 56 ménagé à proximité du bord extérieur des chemins de guidage 3.In this fourth embodiment the rigid members are formed by clips, preferably metallic, having the shape of a U whose free ends of the two wings 10 and 11 form outwardly curved portions 10a and 11a which, as shown in Figure 17, are housed in an inner recess 56 located near the outer edge of the roads guidance 3.

    De plus, ces organes 5 présentent, entre ces parties courbées 10a et 11a et leur extrémité saillante 6 serrée autour du bourrelet 7 du rideau, une partie emboutie 57 servant d'appui pour les différents organes 5 l'un contre l'autre sur les bords latéraux 2 du rideau, à l'intérieur des chemins de guidage 3.In addition, these organs 5 have, between these curved parts 10a and 11a and their projecting end 6 tight around the bead 7 of the curtain, part stamped 57 serving as support for the various organs 5 one against the other on the side edges 2 of the curtain, inside the guideways 3.

    Lorsqu'une force de traction, suivant la direction de la flèche F, est exercée sur le rideau 1, les bords latéraux 2 peuvent se dégager de leurs chemins de guidage 3 par le fait que les parties courbées 10a et 11a se replient élastiquement vers l'intérieur, comme montré à la figure 18.When a tensile force, depending on the direction of arrow F, is exerted on the curtain 1, the side edges 2 can be cleared from their paths guide 3 by the fact that the curved parts 10a and 11a fold inwards elastically, as shown in Figure 18.

    Les figures 19, 20 et 21 concernent une cinquième forme de réalisation de l'invention particulièrement intéressante, qui se distingue essentiellement par rapport aux formes de réalisation précédentes par le fait que les organes rigides 5, fixés aux bords latéraux 2 du rideau 1, coopèrent entr'eux par l'intermédiaire d'un accouplement à rotule 28.Figures 19, 20 and 21 relate to a fifth embodiment of the invention particularly interesting, which stands out basically compared to the embodiments previous by the fact that the rigid members 5, fixed at the lateral edges 2 of the curtain 1, cooperate between them by via a ball joint 28.

    Dans cette forme de réalisation particulière cet accouplement à rotule comprend un logement sphérique 29 à une des extrémités de l'organe rigide 5 et un pivot à tête sphérique 30 à l'extrémité opposée de cet organe rigide 5. La tête du pivot 30 d'un organe rigide est articulée dans le logement 29 de l'organe rigide suivant adjacent, comme illustré clairement par la figure 21.In this embodiment particular this ball joint coupling includes a housing spherical 29 at one end of the rigid member 5 and a ball head pivot 30 at the opposite end of this rigid member 5. The pivot head 30 of a rigid member is articulated in the housing 29 of the rigid member next adjacent, as clearly illustrated in the figure 21.

    De plus, aussi bien le logement 29 que le pivot 30 sont fendus suivant la direction longitudinale des bords 2. Ainsi, en pressant le pivot 30 dans son logement correspondant 29, le pivot est légèrement comprimé alors que le logement peut subir une certaine dilatation, de manière à assurer ainsi une fixation fiable de deux organes rigides successifs l'un par rapport à l'autre, tout en permettant une articulation de ces derniers suivant toutes les directions. La nature de cette compression et cette dilatation est bien entendu fonction des matériaux dont est constitué l'organe 5.In addition, both the housing 29 and the pivot 30 are split in the longitudinal direction of edges 2. Thus, by pressing the pivot 30 in its housing corresponding 29, the pivot is slightly compressed then that the housing can undergo a certain expansion, so as to thus ensure a reliable fixing of two organs rigid successive with respect to each other, while allowing an articulation of these following all directions. The nature of this compression and this expansion is of course a function of the materials of which constituted the organ 5.

    Lorsque les bords latéraux 2 du rideau 1 sont pourvus d'un bourrelet 7, comme c'est le cas dans la présente forme de réalisation, les organes rigides 5 s'étendent aussi bien avec leur pivot 30 qu'avec leur logement correspondant 29 autour du bourrelet 7, comme illustré clairement par la figure 20.When the side edges 2 of the curtain 1 are provided with a bead 7, as is the case in the present embodiment, the rigid members 5 extend as well with their pivot 30 as with their corresponding housing 29 around the bead 7, as illustrated clearly in Figure 20.

    Les figures 22 et 23 concernent une sixième forme de réalisation du dispositif de fermeture, suivant l'invention, qui se distingue essentiellement par rapport à la précédente forme de réalisation par le fait que chaque organe rigide 5 est pourvu de deux galets 26 permettant ainsi de réduire considérablement le frottement des bords latéraux 2 lors de leur déplacement dans les chemins de guidage 3.Figures 22 and 23 relate to a sixth embodiment of the closure device, according to the invention, which is essentially distinguished by compared to the previous embodiment by the fact that each rigid member 5 is provided with two rollers 26 thus considerably reducing friction side edges 2 when moving in the guideways 3.

    Les figures 24 à 26 se rapportent à une septième forme de réalisation de l'invention d'une exécution relativement simple en ce qui concerne la fixation des organes rigides aux bords latéraux 2 du rideau.Figures 24 to 26 relate to a seventh embodiment of the invention of a relatively simple execution with regard to the fixing the rigid members to the lateral edges 2 of the curtain.

    Cette forme de réalisation se distingue essentiellement par rapport aux formes de réalisation précédentes par le fait qu'aucune finition particulière n'est prévue aux bords latéraux 2. Par exemple, contrairement à ce qui est le cas dans pratiquement toutes les formes de réalisation précédentes, un bourrelet n'est donc pas prévu.This embodiment stands out basically compared to the embodiments previous by the fact that no particular finish is provided at the side edges 2. For example, contrary to what is the case in practically all the previous embodiments, a bead is not therefore not planned.

    De plus, dans cette forme de réalisation, les organes rigides 5 à accouplement à rotule 28 sont formés de deux ailes 10 et 11 articulées l'une à l'autre en 59. Comme illustré clairement par les figures 25 et 26 ces deux ailes sont fixées rigidement de part et d'autre des bords latéraux 2 du rideau. A cet égard, la face de l'aile 10 dirigée vers l'aile 11 est munie d'ergots 14, qui percent dans les bords latéraux 2 du rideau 1 pour pénétrer et se fixer dans des trous correspondants 60 prévus dans la face en regard de l'aile 11.Additionally, in this embodiment, the rigid members 5 with ball joint 28 are formed of two wings 10 and 11 articulated to each other in 59. As clearly illustrated by Figures 25 and 26 these two wings are rigidly fixed on either side of the side edges 2 of the curtain. In this regard, the face of the wing 10 directed towards wing 11 is provided with lugs 14, which pierce in the side edges 2 of the curtain 1 to penetrate and fix in corresponding holes 60 provided in the opposite the wing 11.

    Ces organes 5 peuvent, par exemple, être réalisés en une matière plastique relativement dure, mais présentant une élasticité suffisante pour permettre de fixer élastiquement les ergots 14 dans les trous 16. Au cas de besoin, les pointes 61 des ergots 14 peuvent être pourvues d'un capuchon métallique, non représenté, pour faciliter le perçage des bords latéraux du rideau 1.These organs 5 can, for example, be made of relatively hard plastic, but having sufficient elasticity to allow Elastically fix the pins 14 in the holes 16. Au if necessary, the points 61 of the pins 14 can be provided with a metal cap, not shown, for facilitate the drilling of the side edges of the curtain 1.

    Les figures 27 à 29 concernent une huitième forme de réalisation qui se distingue par rapport à celle suivant les figures 19 à 21 par le fait que l'accouplement à rotule 28 comprend, entre chaque organe rigide 5, une bille fendue 62 s'engageant partiellement dans un logement correspondant 29 prévu aux deux extrémités opposées de chaque organe rigide 5. Il s'agit de logements analogues à ceux prévus dans la forme de réalisation montrée aux figures 19 à 21.Figures 27 to 29 relate to a eighth embodiment that stands out compared to that according to FIGS. 19 to 21 by the fact that the ball joint 28 comprises, between each member rigid 5, a split ball 62 partially engaging in a corresponding housing 29 provided at both ends opposite of each rigid member 5. These are housings analogous to those provided in the embodiment shown in Figures 19-21.

    Les figures 30 à 32 sont relatives à une neuvième forme de réalisation du dispositif de fermeture suivant l'invention.Figures 30 to 32 relate to a ninth embodiment of the closure device according to the invention.

    Cette forme de réalisation se distingue essentiellement par rapport aux précédentes formes de réalisation par le fait que l'on fait usage d'un rideau 1 dont les bords latéraux 2 ne sont pas nécessairement incompressibles en eux-mêmes suivant leur direction longitudinale, mais ont été rendus indirectement incompressibles par la présence d'une zone de raidissement 1' qui s'étend à proximité de ces bords latéraux 2, en dehors des chemins de guidage 3.This embodiment stands out basically compared to previous forms of realization by the fact that one makes use of a curtain 1 whose side edges 2 are not necessarily incompressible in themselves following their direction longitudinal but were rendered indirectly incompressible by the presence of a stiffening zone 1 'which extends near these lateral edges 2, in outside the guideways 3.

    Ceci présente notamment l'avantage que des précautions particulières ne doivent pas être prises pour la réalisation de ces bords latéraux 2 et que l'on peut par exemple faire usage de bords latéraux formés d'un simple bourrelet ou d'une succession de petits blocs rigides juxtaposés articulés les uns par rapport aux autres, comme par exemple décrits et représentés dans le brevet européen 272.733.This has the particular advantage that special precautions should not be taken for the realization of these side edges 2 and that one can for example make use of side edges formed of a single bead or a succession of small blocks rigid juxtaposed articulated with respect to others, as for example described and represented in the European patent 272,733.

    Ainsi, d'une façon générale, l'expression "bord latéral rendu incompressible" utilisée dans le présent texte désigne tout type de bord latéral qui, combiné avec une zone de raidissement, située soit en dehors des chemins de guidage soit à l'intérieur de ces derniers, permet d'éviter que, lorsqu'une poussée est exercée sur ce bord ou sur cette zone de raidissement 1' dans le sens de fermeture du rideau, ce bord puisse se déformer en se bloquant dans ces chemins de guidage ou en créant des efforts de frottement exagérés qui nuiseraient au bon fonctionnement de l'ensemble du dispositif de fermeture.So, generally speaking, the expression "lateral edge rendered incompressible" used in the this text designates any type of lateral edge which, combined with a stiffening zone, located either in outside the guideways either inside these last, avoids that when a push is exerted on this edge or on this stiffening zone 1 ' in the closing direction of the curtain, this edge can be deform by jamming in these guide paths or by creating exaggerated friction forces which would harm to the proper functioning of the entire device closing.

    Plus concrètement, dans cette neuvième forme de réalisation, la zone de raidissement précitée 1' est formée par une courroie crantée fixée au rideau 1, tandis que les moyens d'entraínement comprennent une poulie crantée 4 tournant autour d'un axe 4' et s'engrenant avec la courroie crantée 1'. Un galet de pression 4" est appliqué élastiquement contre le rideau 1 du côté opposé de celui-ci par rapport à la courroie crantée 1', de manière à assurer un engrenage parfait entre cette dernière 1' et la poulie 4.More concretely, in this ninth embodiment, the aforementioned stiffening zone 1 ' is formed by a toothed belt fixed to the curtain 1, while the drive means include a pulley notched 4 rotating around a 4 'axis and meshing with the toothed belt 1 '. A 4 "pressure roller is applied elastically against curtain 1 on the opposite side of this with respect to the toothed belt 1 ', so that ensure a perfect gear between the latter 1 'and the pulley 4.

    Pour ce qui concerne le bord latéral 2, celui-ci est réalisé par les petits blocs d'une des parties d'une fermeture à glissière connue qui présente donc une certaine compressibilité en soi suivant sa direction longitudinale, mais qui est rendue sensiblement incompressible, suivant la signification donnée ci-dessus.Regarding side edge 2, this is achieved by the small blocks of one of the parts a known zipper which therefore has a some compressibility in itself following its direction longitudinal but which is made substantially incompressible, according to the meaning given above.

    Comme variante à cette neuvième forme de réalisation, on peut envisager de remplacer les petits blocs d'une fermeture à glissière dans les bords latéraux par exemple par une courroie crantée qui fera donc simultanément partie des moyens d'entraínement et du bord latéral 2 même du rideau 1 se déplaçant dans les chemins de guidage 3. As a variant to this ninth form of realization, we can consider replacing the small zipper blocks in the side edges for example by a toothed belt which will therefore simultaneously part of the drive means and the edge lateral 2 even of the curtain 1 moving in the paths of guidance 3.

    Les figures 33 à 35 concernent un perfectionnement apporté au passage d'accès 49 pour la réintroduction automatique d'un bord latéral 2 du rideau 1 qui se serait dégagé de la partie inférieure des chemins de guidage 3 (voir à ce sujet la figure 4).Figures 33 to 35 relate to a improvement made to access passage 49 for the automatic reintroduction of a side edge 2 of the curtain 1 which would have emerged from the lower part of the guide 3 (see figure 4 on this subject).

    Il s'agit d'un perfectionnement qui est particulièrement utile pour les bords latéraux des rideaux suivant les formes de réalisation montrées aux figures 19 à 32.It is an improvement which is particularly useful for the side edges of curtains according to the embodiments shown in Figures 19 to 32.

    En effet, dans certains cas, si au passage d'accès 49 les bords latéraux 2 ne sont pas soutenus lorsque ces derniers sont poussés vers la position de fermeture, c'est-à-dire dans le sens de la flèche 45, comme c'est le cas dans la forme de réalisation montrée à la figure 4, par suite du frottement de ces bords dans les chemins de guidage, le risque existe que ces bords subissent une légère flexion à l'endroit du passage d'accès 49 provoquant leur sortie des chemins de guidage 3.Indeed, in some cases, if at access passage 49 the side edges 2 are not supported when the latter are pushed towards the position closing, that is to say in the direction of arrow 45, as is the case in the embodiment shown in Figure 4, as a result of the friction of these edges in the guide paths, there is a risk that these edges undergo a slight bending at the location of the access passage 49 causing them to exit the guide tracks 3.

    Le perfectionnement, suivant l'invention, consiste à intercaller, dans le passage d'accès 49, entre les deux portions fixes séparées 3a et 3b des chemins de guidage s'étendant dans le prolongement l'un de l'autre un raccord de guidage mobile 58, qui est articulé à son bord supérieur, par l'intermédiaire de charnières 64, à la portion 3a des chemins de guidage 3, de manière à pouvoir basculer entre une première position, dans laquelle ce raccord 58 s'étend dans le prolongement des portions 3a et 3b des chemins de guidage, comme montré à la figure 33, et une seconde position, dans laquelle il est orienté par son ouverture inférieure en dehors des chemins de guidage 3, comme montré à la figure 35.The improvement, according to the invention, consists in interposing, in the access passage 49, between the two separate fixed portions 3a and 3b of the guide extending in the extension of each other a movable guide fitting 58, which is hinged at its edge upper, through hinges 64, to the portion 3a of the guide tracks 3, so that switch between a first position, in which this fitting 58 extends in the extension of portions 3a and 3b of the guide tracks, as shown in FIG. 33, and a second position, in which it is oriented by its lower opening outside the guideways 3, as shown in Figure 35.

    Un ressort 65 permet de maintenir ou de ramener le raccord dans ladite première position.A spring 65 makes it possible to maintain or return the fitting to said first position.

    Ainsi, lorsque, pour l'une ou l'autre raison, les bords latéraux 2 du rideau 1 se sont dégagés de la portion 3b des chemins de guidage lors du déplacement du rideau vers sa position d'ouverture, comme indiqué par la flèche 66 sur la figure 34, le raccord 58 sera automatiquement amené dans ladite seconde position pour permettre ainsi la réintroduction de ce bord 2 dans la portion 3a du chemin de guidage 3.So when, for one or the other reason, the side edges 2 of the curtain 1 are free from the portion 3b of the guide paths during the displacement of the curtain towards its open position, as indicated by the arrow 66 in FIG. 34, the fitting 58 will be automatically brought into said second position for thus allow the reintroduction of this edge 2 into the portion 3a of the guide path 3.

    Lorsque le bord transversal inférieur du rideau et de ces bords latéraux 2 arrivent au niveau du raccord 58 ou éventuellement au-dessus de ce dernier, il reprendra automatiquement sa première position, comme montré à la figure 33. Pour amener ensuite le rideau dans sa position de fermeture, ces bords latéraux seront donc parfaitement guidés sur toute la longueur des chemins de guidage, évitant ainsi tout risque d'obstruction ou de dégagement de ces bords à la hauteur du passage d'accès 49.When the lower transverse edge of the curtain and these side edges 2 arrive at the fitting 58 or possibly above it will automatically resume its first position, as shown in Figure 33. Then bring the curtain in its closed position, these side edges will therefore perfectly guided along the entire length of the guidance, thus avoiding any risk of obstruction or clearance of these edges at the level of the access passage 49.

    Afin d'assurer une parfaite continuité dans les chemins de guidage et le raccord 58, dans sa première position, celui-ci présente avantageusement une section intérieure identique à celle des portions fixes 3a et 3b des chemins de guidage de manière à former ainsi un canal de guidage entièrement continu.To ensure perfect continuity in the guideways and the fitting 58, in its first position, it advantageously has a inner section identical to that of the fixed portions 3a and 3b guide tracks so as to form a fully continuous guide channel.

    Il y a encore lieu de remarquer que dans les figures 33 et 34 les bords latéraux 2 du rideau 1 n'ont pas été représentés, de sorte que l'on peut supposer que le rideau se trouve dans sa position d'ouverture. Par contre, dans la figure 35, on s'est limité à représenter un bord latéral par des organes rigides 5 coopérant entr'eux par l'intermédiaire de billes 62, comme dans les bords latéraux de la forme de réalisation représentée aux figures 27 à 29.It should also be noted that in Figures 33 and 34 the side edges 2 of the curtain 1 have not been represented, so we can assume that the curtain is in its open position. On the other hand, in figure 35, we have limited ourselves to representing an edge lateral by rigid members 5 cooperating between them by through balls 62, as in the lateral edges of the embodiment shown in Figures 27 to 29.

    Une variante intéressante du dispositif de fermeture suivant l'invention, consiste à prévoir, comme moyens qui permettent d'éviter la compression des bords latéraux 2 du rideau 1 suivant la direction de leur longueur au moins lors du déplacement de ce dernier vers sa position de fermeture, un mécanisme d'entraínement comprenant par exemple un câble et des poulies de renvoi appliquant une traction sur ces bords latéraux pour provoquer la fermeture du rideau. Dans cette variante, il ne faut pas nécessairement que les bords latéraux 2 soient incompressibles ou rendus incompressibles dans le sens de leur longueur.An interesting variant of the device according to the invention, consists in providing, as means to avoid edge compression side 2 of curtain 1 in the direction of their length at least when moving the latter towards its closed position, a drive mechanism for example comprising a cable and pulleys applying traction on these side edges to cause the curtain to close. In this variant, it side edges 2 don't necessarily have to be incompressible or made incompressible in the sense of their length.

    De plus, dans cette variante, le rideau est tendu entre les chemins de guidage 3, dans lesquels se déplacent ces bords, au moins lorsqu'il se trouve dans sa position de fermeture.In addition, in this variant, the curtain is stretched between the guide tracks 3, in which move these edges, at least when it's in its closed position.

    Ceci a comme grand avantage que, de cette façon, on peut également éviter l'utilisation d'un élément de raidissement, par exemple sous forme d'une barre rigide, à proximité du bord libre inférieur du rideau 1. Dans ce cas, le rideau est de préférence entièrement souple, sans aucun élément de raidissement transversal.This has the great advantage that, from this way we can also avoid the use of an element stiffening, for example in the form of a rigid bar, near the lower free edge of the curtain 1. In this case, the curtain is preferably fully flexible, without no transverse stiffening element.

    Il est bien entendu que l'invention n'est pas limitée aux différentes formes de réalisation décrites ci-dessus et représentées aux figures annexées, mais que bien d'autres variantes encore pourraient être envisagées sans sortir du cadre de la présente invention.It is understood that the invention is not not limited to the various embodiments described above and shown in the accompanying figures, but that many other variations could be considered without departing from the scope of the present invention.

    Ainsi, les bords latéraux 2 du rideau 1 pourraient être rendus sensiblement incompressibles dans la direction de leur longueur en prévoyant, à proximité de ces bords, une succession de plaquettes rigides fixées au rideau et situées en dehors des chemins de guidage ou par la fixation contre le rideau 1 d'une bande de tissu armée suivant le sens de déplacement du rideau permettant ainsi d'éviter que dans cette zone et donc également à l'endroit des bords latéraux le rideau puisse se froncer lorsqu'une force de poussée est exercée, dans le sens de fermeture du rideau, soit directement sur les bords latéraux soit sur cette bande armée. Dans ce cas, les bords latéraux pourraient simplement être constitués par le bourrelet 7, par exemple.So the side edges 2 of the curtain 1 could be made substantially incompressible in the direction of their length by predicting, near these edges, a succession of rigid plates fixed to the curtain and located outside the guideways or by fixing against curtain 1 a strip of reinforced fabric following the direction of movement of the curtain thus allowing to avoid that in this area and therefore also in the place from the side edges the curtain may gather when a pushing force is exerted, in the closing direction of the curtain, either directly on the side edges or on this armed band. In this case, the side edges could simply consist of the bead 7, for example.

    Dans d'autres cas encore, les bords latéraux pourraient être rendus sensiblement incompressibles dans le sens de leur longueur en introduisant dans celui-ci une succession de billes quelque peu analogue aux billes 62 de la forme de réalisation montrée aux figures 27 à 29. Le cas échéant, ces billes pourraient être introduites dans la conduite creuse 8, qui formerait une gaine pour les billes et qui, dans ce cas, aurait une section quelque peu plus grande que celle des formes de réalisation représentées aux figures annexées.In still other cases, the edges side could be made noticeably incompressible in the sense of their length in introducing into it a succession of balls some not very similar to the balls 62 of the embodiment shown in Figures 27 to 29. Where appropriate, these balls could be introduced into the hollow pipe 8, which would form a sheath for the balls and which, in this case, would have a section somewhat larger than that of embodiments shown in the accompanying figures.

    Une autre variante consisterait à prévoir des petits blocs rigides, qui seraient par exemple moulés sur les bords latéraux du rideau, par exemple comme les dents d'une fermeture à glissière, entre lesquels serait prévu un joint souple, mais non compressible.Another variant would be to plan small rigid blocks, which would for example be molded on the side edges of the curtain, for example like the teeth of a zipper, between which would provided a flexible, but non-compressible seal.

    Par ailleurs, il n'est pas indispensable que l'arbre 20 s'étende sur toute la largeur du rideau. Dans un cas extrême, cet arbre peut être formé par deux tronçons coaxiaux à proximité des bords latéraux du rideau pour l'entraínement du bras télescopique 19. Aussi, si on fait usage d'autres moyens d'entraínement 4, ne nécessitant pas un tel arbre 20, comme c'est par exemple le cas dans les formes de réalisation représentées aux figures 14 à 16, un tel arbre pourrait être omis.Furthermore, it is not essential that the shaft 20 extends over the entire width of the curtain. In an extreme case, this tree can be formed by two coaxial sections near the side edges of the curtain for driving the telescopic arm 19. Also, if we makes use of other training means 4, not requiring not such a tree 20, as it is for example the case in the embodiments shown in Figures 14 to 16, such a tree could be omitted.

    Par ailleurs, en l'absence d'un arbre d'entraínement, le rideau ne doit pas nécessairement s'enrouler mais peut par exemple se déplacer dans un plan incliné quelconque, horizontal ou vertical de sa position de fermeture vers sa position d'ouverture.By the way, in the absence of a tree curtain, the curtain does not necessarily have to roll up but can for example move in a plane any incline, horizontal or vertical from its position closing to its open position.

    Si le rideau se déplace entre sa position de fermeture et sa position d'ouverture dans un même plan, les bords latéraux ne doivent pas nécessairement être flexibles.If the curtain moves between its position and its open position in the same plane, the side edges do not have to be Flexible.

    L'invention n'est également pas limitée à des rideaux se déplaçant dans un plan vertical, mais concerne également des rideaux se déplaçant horizontalement par exemple pour couvrir des piscines ou silos.The invention is also not limited to curtains moving in a vertical plane but also relates to curtains moving horizontally for example to cover swimming pools or silos.

    Dans certains cas, l'enroulement du rideau peut être réalisé à partir du bord inférieur, donc contrairement aux formes de réalisation montrées aux figures annexées.In some cases, the winding of the curtain can be made from the bottom edge, so unlike the embodiments shown in attached figures.
