Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention est relative à un rideau de sécurité transparent, du type enroulable autour d'un tambour disposé à sa partie supérieure, ledit rideau permettant, lorsqu'il est baissé et fermé, de protéger contre le vandalisme et le vol une vitrine, une devanture de magasin par exemple, sans affecter la visibilité de celle-ci, ou encore permettant de protéger une fenêtre ou une porte-fenêtre d'un local d'habitation, ledit rideau étant en outre du genre constitué d'une pluralité de lames transparentes, qui sont disposées horizontalement, les unes au dessus des autres.The present invention relates to a transparent safety curtain, the type rollable around a drum disposed at its upper part, said curtain allowing, when lowered and closed, to protect against vandalism and theft a showcase, a Storefront for example, without affecting the visibility of the latter, or to protect a window or a French window of a living space, said curtain being furthermore of the kind consisting of a plurality of transparent blades , which are arranged horizontally, one above the other.

ARRIÈRE PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

On connaît actuellement deux principaux types d'un tel rideau de sécurité transparent.There are currently two main types of such a transparent security curtain.

Dans le premier type, décrit par exemple dans la demande de brevet internationale publiée sous le n° WO 2007/024131 , au nom de Europ Look Beheer B.V., les lames transparentes comportent en excroissances, sur chacun de leurs deux bords longitudinaux, des tronçons de tubes cylindriques disposés en quinconce, la longueur de chaque tronçon étant très légèrement inférieure à la distance séparant deux tronçons consécutifs. Pour réunir deux lames de ce genre, on dispose les tronçons de tubes de l'une dans les intervalles laissées entre les tronçons de tubes de l'autre et on assemble les deux lames ainsi disposées en glissant à l'intérieur des tronçons tubulaires cylindriques alors situés dans le prolongement les uns des autres une tige dont le diamètre est très légèrement inférieur au diamètre intérieur des tronçons tubulaires.In the first type, described for example in the international patent application published under No. WO 2007/024131 , on behalf of Europ Look Beheer BV, the transparent blades comprise in excrescences, on each of their two longitudinal edges, sections of cylindrical tubes arranged in staggered rows, the length of each section being very slightly less than the distance separating two consecutive sections. To join two blades of this kind, the pipe sections of one are arranged in the gaps left between the pipe sections of the other and the two blades thus arranged are assembled by sliding inside the cylindrical tubular sections then located in the extension of each other a rod whose diameter is very slightly less than the inner diameter of the tubular sections.

Ainsi à la manière d'une charnière de piano, la tige constitue un verrou et un axe d'articulation horizontal pour les deux lames concernées. Les lames, qui sont fabriquées d'une pièce avec leurs tronçons de tubes cylindriques formant des excroissances, sont en général en polycarbonate et les tiges d'articulation sont en acier.Thus in the manner of a piano hinge, the rod constitutes a latch and a horizontal axis of articulation for the two blades concerned. The blades, which are made of a piece with their sections of cylindrical tubes forming excrescences, are generally made of polycarbonate and the hinge pins are made of steel.

Dans le second type, décrit par exemple dans le brevet français FR-87.11017 au nom de Peyrichou-Malan, les lames sont chacune réunies à la lame immédiatement supérieure au moyen de deux profilés de sections complémentaires enclenchés. Ces deux profilés enclenchés constituent également simultanément un verrou et un axe d'articulation horizontal pour les deux lames concernées. Dans ce type de rideau, les lames transparentes sont insérées entre les profilés et, soit les lames, soit les profilés, coulissent à chacune de leurs deux extrémités dans une glissière latérale verticale fixée à la menuiserie qui délimite la vitrine ou la devanture à protéger. Les lames d'un tel rideau sont en général en polycarbonate et les profilés sont de préférence en aluminium.In the second type, described for example in the French patent FR-87.11017 in the name of Peyrichou-Malan, the blades are each joined to the next higher blade by means of two sections of complementary sections engaged. These two interlocked profiles also simultaneously constitute a latch and a horizontal axis of articulation for the two blades concerned. In this type of curtain, the transparent blades are inserted between the profiles and either the blades or the profiles, slide at each of their two ends in a vertical side slide fixed to the joinery that defines the storefront or storefront to protect. The blades of such a curtain are generally polycarbonate and the profiles are preferably aluminum.

Le rideau de sécurité transparent conforme à l'invention constitue une amélioration des rideaux du second type décrit ci-dessus.The transparent safety curtain according to the invention constitutes an improvement of the curtains of the second type described above.

En effet, dès lors que les largeurs des vitrines ou devantures de magasins, de même que les largeurs des fenêtres, sont variables, il convient de prévoir ou de découper sur place des lames d'une longueur correspondant à la largeur de la baie à recouvrir, compte tenu au surplus des dimensions et des épaisseurs des glissières latérales verticales.Indeed, since the widths of storefronts or storefronts, as well as the widths of the windows, are variable, it is appropriate to provide or cut on the spot blades of a length corresponding to the width of the bay to cover , in addition to the dimensions and thicknesses of the vertical side rails.

De telles lames sont donc particulièrement encombrantes. Au surplus, s'il y a une erreur dans la découpe, les lames sont inexploitables, du moins pour la baie que l'on désirait recouvrir, et elles sont alors soit jetées soit stockées dans l'espoir de pouvoir être réexploitées pour recouvrir une baie d'une largeur plus réduite.Such blades are therefore particularly bulky. Moreover, if there is an error in cutting, the blades are unusable, at least for the bay that was desired to cover, and they are either discarded or stored in the hope of being reused to cover a bay with a smaller width.

En outre, les lames transparentes étant insérées à force dans des évidements correspondants prévus dans les faces des profilés opposées à leurs faces de verrouillage, chaque rideau de sécurité du second type doit être intégralement monté avant d'être placé entre les deux glissières latérales verticales, par coulissement depuis la partie supérieure de celles-ci, ce qui implique que, pour accomplir toutes les opérations préliminaires indispensables, l'installateur dispose d'un large volume disponible à l'intérieur du magasin à équiper.In addition, the transparent blades being forcibly inserted into corresponding recesses provided in the faces of the profiles opposite to their locking faces, each safety curtain of the second type must be fully assembled before to be placed between the two vertical lateral slides, by sliding from the upper part thereof, which implies that, to perform all the essential preliminary operations, the installer has a large volume available inside the store to equip.

Le document AU-B-56317 décrit un rideau de sécurité conforme au préambule de la revendication 1.The document AU-B-56317 discloses a safety curtain according to the preamble of claim 1.

DESCRIPTION GÉNÉRALE DE L'INVENTIONGENERAL DESCRIPTION OF THE INVENTION

Ainsi, le rideau de sécurité transparent conforme à l'invention est caractérisé en ce que chacune de ses lames est formée d'une pluralité de modules de section en I assemblés deux à deux à chevauchement latéral, les ailes haute et basse desdits modules étant insérées par coulissement avec un léger jeu entre deux rails en vis-à-vis, pratiqués sur les faces des profilés opposées à leurs faces de verrouillage, respectivement le profilé supérieur et le profilé inférieur, et en ce que chaque module extrémal de chaque lame est abouté à un embout de blocage sécable.Thus, the transparent safety curtain according to the invention is characterized in that each of its blades is formed of a plurality of I-section modules assembled in pairs overlapped sideways, the upper and lower wings of said modules being inserted by sliding with a slight clearance between two rails vis-à-vis, made on the faces of the profiles opposite their locking faces, respectively the upper profile and the lower profile, and in that each end module of each blade is butted to a breakable locking tip.

Les modules sont soit assemblés à simple recouvrement, soit enclenchés à force.The modules are either assembled with single overlap or forcibly engaged.

Dans l'une et l'autre des deux réalisations précitées, les modules ont une largeur de quelques dizaines de centimètres, de préférence de l'ordre de 30 centimètres.In both of the aforementioned embodiments, the modules have a width of a few tens of centimeters, preferably of the order of 30 centimeters.

Dans la première des deux réalisations précitées, les modules comportent sur chacun de leurs deux bords latéraux verticaux une saillie en Z, l'aile extrémale de cette saillie étant décalée par rapport à l'âme du module, tout en étant parallèle à ladite âme, et le plan de la face intérieure de ladite aile extrémale étant confondu avec le plan de la face de l'âme en direction de laquelle la saillie est décalée.In the first of the two aforementioned embodiments, the modules comprise on each of their two vertical lateral edges a projection in Z, the extremal wing of this projection being offset with respect to the core of the module, while being parallel to said core, and the plane of the inner face of said extremal wing coinciding with the plane of the face of the soul towards which the projection is offset.

Dans cette construction, les saillies en Z formées le long des deux bords latéraux de chaque module sont alors avantageusement d'orientations inverses de sorte que la face intérieure de chaque aile extrémale soit en contact avec la face de l'âme d'un module voisin.In this construction, the Z-shaped protrusions formed along the two lateral edges of each module are then advantageously of opposite orientations so that the inner face of each extremal wing is in contact with the face of the soul of a neighboring module. .

Dans la seconde des deux réalisations précitées, l'enclenchement à force des deux modules est obtenu par le verrouillage d'un crochet, formé le long du bord vertical de chaque module, dans une rainure verticale complémentaire creusée dans l'âme à proximité du bord vertical de l'autre module, légèrement en retrait de son crochet.In the second of the two embodiments mentioned above, the forced engagement of the two modules is obtained by locking a hook, formed along the vertical edge of each module, in a complementary vertical groove dug in the core near the edge. vertical of the other module, slightly behind its hook.

Fort avantageusement, dans cette seconde réalisation, les deux crochets formés le long des deux bords verticaux de chaque module sont d'orientations inverses et les deux rainures verticales sont creusées l'une dans une face et l'autre dans l'autre face de l'âme dudit module.Advantageously, in this second embodiment, the two hooks formed along the two vertical edges of each module are of opposite orientations and the two vertical grooves are hollowed one in one face and the other in the other face of the soul of said module.

Avantageusement, chaque embout de blocage se compose d'un socle dont la largeur est sensiblement égale à celle des profilés et dont la hauteur est sensiblement égale à la distance séparant les centres des deux arrondis complémentaires constituant les moyens de verrouillage de deux profilés montés sur une même lame, ledit socle étant prolongé d'une âme qui lui est perpendiculaire, dont la section est sensiblement identique à celle des modules, ladite âme étant prolongée en parties haute et basse d'un retour orthogonal s'étendant de part et d'autre de l'âme, plus épais que l'aile d'un module et coulissant donc à force dans le rail d'un profilé, ladite âme comportant en outre à son extrémité libre une pluralité de fentes verticales facilitant la découpe et la mise parfaite à longueur de l'âme afin que son about soit au contact du module extrémal de la lame dont elle constitue la terminaison.Advantageously, each locking endpiece consists of a base whose width is substantially equal to that of the profiles and whose height is substantially equal to the distance separating the centers of the two complementary rounds constituting the locking means of two profiles mounted on a same blade, said base being extended by a soul which is perpendicular to it, whose section is substantially identical to that of the modules, said core being extended in the upper and lower parts of an orthogonal return extending on either side of the core, thicker than the wing of a module and thus sliding forcibly in the rail of a profile, said core further comprising at its free end a plurality of vertical slots facilitating the cutting and the perfect setting to length of the soul so that its end is in contact with the extremal module of the blade which it is the termination.

De préférence, le socle de chaque embout de blocage est percé de deux orifices traversants au droit des gorges des rails des deux profilés montés sur une même lame et chaque orifice reçoit une vis dont la tige filetée vient se visser en partie centrale du retour orthogonal monté à force à coulissement dans un rail.Preferably, the base of each locking piece is pierced with two through holes in the grooves of the rails of the two sections mounted on the same blade and each orifice receives a screw whose threaded rod is screwed into the central portion of the orthogonal return mounted slidably in a rail.

De préférence également, chacun des deux retours de l'âme de chaque embout de blocage présente sur sa face externe une rainure longitudinale qui reçoit la tige filetée afin que le filet de ladite vis coopère avec le fond de ladite rainure et avec le fond du rail du profilé.Also preferably, each of the two returns of the core of each locking tip has on its outer face a longitudinal groove which receives the threaded rod so that the thread of said screw cooperates with the bottom of said groove and with the bottom of the profile rail.

Avantageusement, ladite rainure longitudinale s'étend depuis le socle de l'embout de blocage jusqu'à la première fente verticale.Advantageously, said longitudinal groove extends from the base of the locking end to the first vertical slot.

Afin de rendre chaque embout de blocage aisément sécable, chaque fente verticale est pratiquée de sorte à laisser seulement quelques parties de matière de l'âme, lesdites parties de matière étant espacées et étant au surplus d'épaisseur réduite.In order to make each locking tip easily breakable, each vertical slot is made to leave only a few portions of material of the core, said portions of material being spaced apart and being further reduced in thickness.

Pour sécuriser au maximum le rideau de sécurité transparent selon l'invention, tant à l'égard du vandalisme qu'à l'égard de violentes perturbations atmosphériques (rafales de vent, tempêtes), les embouts de blocage ont un déplacement latéral limité entre les deux ailes de chaque glissière verticale.In order to make the transparent safety curtain according to the invention as secure as possible with respect to vandalism and with regard to violent atmospheric disturbances (gusts of wind, storms), the locking ends have a limited lateral displacement between them. two wings of each vertical slide.

De préférence, la lame transparente inférieure est articulée sur une lame finale en aluminium extrudé qui est dotée en partie basse d'un rail apte à recevoir un joint d'étanchéité et qui est pourvue d'un organe permettant son verrouillage en partie basse de la vitrine ou de la devanture du magasin à protéger.Preferably, the lower transparent blade is articulated on a final extruded aluminum blade which is provided at the bottom with a rail adapted to receive a seal and which is provided with a member allowing its locking in the lower part of the showcase or storefront to protect.

DESCRIPTION DES MODES DE RÉALISATION PRÉFÉRÉS DE L'INVENTIONDESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Un rideau de sécurité transparent conforme à l'invention a été représenté à la Figure 1.A transparent security curtain in accordance with the invention has been shown in FIG. Figure 1 .

Ce rideau 1, du type enroulable autour d'un tambour disposé à sa partie supérieure, par exemple encastré dans un coffret 2, permet lorsqu'il est baissé et fermé de protéger, contre le vandalisme et le vol, une vitrine ou une devanture de magasin par exemple, sans affecter la visibilité de celle-ci, ou encore de protéger une fenêtre ou une porte-fenêtre d'un local d'habitation, par exemple une villa ou l'appartement d'un immeuble.This curtain 1, of the type windable around a drum disposed at its upper part, for example recessed in a box 2, allows when lowered and closed to protect, against vandalism and theft, a window or a storefront of shop, without affecting the visibility of the shop, or protecting a window or French window dwelling, for example a villa or the apartment of a building.

A cette fin, le rideau est constitué d'une pluralité de lames transparentes 3 qui sont disposées horizontalement les unes au-dessus des autres et qui sont chacune réunies à la lame immédiatement supérieure au moyen de deux profilés de sections complémentaires, respectivement supérieur 4 et inférieur 5, ainsi qu'il est visible aux Figures 25 et 26.To this end, the curtain is constituted by a plurality of transparent blades 3 which are arranged horizontally one above the other and which are each joined to the next higher blade by means of two profiles of complementary sections, respectively upper 4 and less than 5, as is visible Figures 25 and 26 .

Lorsqu'ils sont enclenchés par paire, les profilés 4 et 5 constituent simultanément un verrou et un axe d'articulation horizontale pour les deux lames 3 concernées.When they are engaged in pairs, the sections 4 and 5 simultaneously constitute a latch and a horizontal hinge axis for the two blades 3 concerned.

Le rideau selon l'invention est en outre du type de ceux dans lesquels les lames 3 sont insérées entre les profilés 4 et 5 et dans lesquels les profilés 4,5 et/ou les lames 3 coulissent à chacune de leurs deux extrémités dans une glissière latérale verticale 6 fixée à la menuiserie 6' qui délimite la vitrine ou devanture à protéger.The curtain according to the invention is also of the type in which the blades 3 are inserted between the sections 4 and 5 and in which the profiles 4,5 and / or the blades 3 slide at each of their two ends in a slideway vertical side 6 attached to the joinery 6 'which defines the window or storefront to protect.

Conformément à l'invention, chacune des lames 3 du rideau de sécurité 1 est formée d'une pluralité de modules 7 ou 12 de section en I assemblés deux à deux à chevauchement latéral.According to the invention, each of the blades 3 of the safety curtain 1 is formed of a plurality of modules 7 or 12 of section I assembled side by side in pairs.

Selon sa première variante représentée aux Figures 5 à 8 et 29, les modules 7, qui ont fort avantageusement mais non limitativement une largeur de l'ordre de 30 centimètres, sont assemblés à simple recouvrement.According to his first variant represented in Figures 5 to 8 and 29 the modules 7, which have a very advantageous but non-limiting width of the order of 30 centimeters, are assembled with single overlap.

A cet effet, l'âme 8 de chaque module 7 a ses deux bords latéraux verticaux 9 et 10 légèrement affinés et coudés deux fois en sens inverse de sorte à former une saillie 11 en Z. L'aile extrémale de cette saillie en Z est ainsi décalée par rapport à l'âme 8, tout en étant parallèle à ladite âme, et le plan de la face intérieure 11' de ladite aile extrémale est alors confondu avec le plan de la face 11" de l'âme en direction de laquelle elle est décalée.For this purpose, the core 8 of each module 7 has its two vertical lateral edges 9 and 10 slightly refined and bent twice in opposite directions so as to form a projection 11 in Z. The extremal wing of this projection Z is thus shifted with respect to the core 8, while being parallel to said core, and the plane of the inner face 11 'of said extremal wing is then merged with the plane of the face 11 "of the core towards which she is shifted.

En outre, dans cette première variante, les saillies en Z 11 formées le long des deux bords latéraux 9 et 10 de chaque module 7 sont d'orientations inverses. Ainsi, les modules 7 intégrés entre les rails 4 et 5 les uns à la suite des autres afin de constituer une lame 3 pourront être assemblés, aboutés deux à deux, avec chevauchement à simple recouvrement des ailes extrémales des deux saillies en Z, les faces intérieures 11' desdites deux saillies 11 en Z étant légèrement décalées l'une par rapport à l'autre et étant chacune en contact avec la face 11" de l'âme 8 du module 7 immédiatement voisin, ainsi qu'il est bien visible à la Figure 29.In addition, in this first variant, the Z projections 11 formed along the two lateral edges 9 and 10 of each module 7 are of opposite orientations. Thus, the modules 7 integrated between the rails 4 and 5 one after the other in order to form a blade 3 can be assembled, abutting two by two, overlap single overlap of the extremal wings of the two projections in Z, the inner faces 11 'of said two Z projections 11 being slightly offset relative to each other and each being in contact with the face 11 "of the core 8 of the immediately adjacent module 7, as is clearly visible in FIG. Figure 29 .

Selon sa seconde variante représentée aux Figures 9 à 13, les modules 12, qui ont de préférence une largeur également de l'ordre de 30 centimètres, sont enclenchés à force.According to its second variant represented in Figures 9 to 13 the modules 12, which preferably have a width also of the order of 30 centimeters, are forcibly engaged.

A cet effet, chacune des deux extrémités latérale 13 et 14 de l'âme 15 de chaque module 12 est coudée trois fois de sorte à former un crochet vertical 16 qui est tourné vers le plan médian 17 mais qui n'atteint pas ce plan médian.For this purpose, each of the two lateral ends 13 and 14 of the core 15 of each module 12 is bent three times so as to form a vertical hook 16 which is turned towards the median plane 17 but which does not reach this median plane. .

La face 18 de l'âme 15 de chaque module vers laquelle est tourné le crochet 16 présente en outre une rainure verticale 19 apte à recevoir le crochet 16 identique d'un autre module.The face 18 of the core 15 of each module to which the hook 16 is rotated further has a vertical groove 19 adapted to receive the hook 16 identical to another module.

Ainsi, lorsque deux modules 12 sont rapprochés, leurs deux crochets 16 passent l'un au-dessus de l'autre puis, lorsque les deux modules sont aboutés, chaque crochet 16 de chaque module 12 vient se loger à force dans la rainure 19 de l'autre module, d'où l'enclenchement entre les deux modules 12 et leur autoverrouillage.Thus, when two modules 12 are close together, their two hooks 16 pass one above the other then, when the two modules are butted, each hook 16 of each module 12 is forcibly housed in the groove 19 of the other module, hence the engagement between the two modules 12 and their self-locking.

Dans les deux variantes précitées, les ailes hautes 20 et basse 21 des modules 7, 12 sont insérées par coulissement avec un léger jeu entre les rails en vis-à-vis, respectivement 22 et 23, des profilés supérieur 4 et inférieur 5, rails qui sont prévus chacun sur la face du profilé qui est opposée à la face utilisée pour le verrouillage.In the two aforementioned variants, the upper and lower wings 20 of the modules 7, 12 are slidably inserted with a slight clearance between the rails facing each other, respectively 22 and 23, of the upper and lower rails 5 and 5, respectively. which are each provided on the face of the profile which is opposite to the face used for locking.

Chaque aile 20, 21 comporte à cette fin deux rainures 24 en vis-à-vis, délimitées chacune par la tête de l'aile 20, 21 à proprement parler et par un épaulement 25, les rainures 24 étant aptes à coopérer avec les retours 26 des rails 22, 23 et, pour cela, étant d'une largeur légèrement supérieure à l'épaisseur des retours 26. La hauteur des têtes des ailes 20, 21 est bien sûr, pour les mêmes raisons, légèrement inférieure à la hauteur des gorges intérieures des rails 22, 23.Each wing 20, 21 comprises for this purpose two grooves 24 vis-à-vis, each delimited by the head of the wing 20, 21 strictly speaking and by a shoulder 25, the grooves 24 being able to cooperate with the returns 26 rails 22, 23 and, for this, being of a width slightly greater than the thickness of the returns 26. The height of the heads of the wings 20, 21 is of course, for the same reasons, slightly less than the height of the inner grooves of the rails 22, 23.

Dès lors que, après montage, les modules 7, 12 ont été glissés entre les profilés 4 et 5 et ont été ajustés les uns par rapport aux autres, soit par simple recouvrement pour ce qui est des modules 7, soit emboîtés par leurs crochets 16 et leurs rainures 19 pour ce qui est des modules 12, on comprend que, du fait qu'il n'existe qu'un très léger jeu entre les ailes 20 et 21 des modules 7 ou 12 et les rails 22 et 23 des profilés 4, 5, il est impossible que les modules se déboîtent et que les lames puissent ainsi être démontées.Since, after assembly, the modules 7, 12 have been slid between the profiles 4 and 5 and have been adjusted relative to each other, either by simple overlap with respect to the modules 7, or nested by their hooks 16 and their grooves 19 for the modules 12, it is understood that, because there is only a slight clearance between the wings 20 and 21 of the modules 7 or 12 and the rails 22 and 23 of the profiles 4 , 5, it is impossible for the modules to disengage and the blades can thus be dismounted.

La succession des modules 7 ou 12 entre deux rails 4 et 5 a une longueur qui ne correspond pas nécessairement à la largeur disponible entre les deux glissières verticales 6 de la vitrine ou de la devanture, ou encore de la fenêtre à protéger.The succession of modules 7 or 12 between two rails 4 and 5 has a length that does not necessarily correspond to the width available between the two vertical rails 6 of the window or the front, or the window to be protected.

Afin d'approcher au plus près cette largeur, on placera en conséquence, au moins à proximité de l'une des glissières verticales 6, un tronçon 41 du module 7 ou 12 approprié à la construction déjà réalisée et, à chacune des deux extrémités de la lame 3 ainsi constituée, on parachèvera la construction en intégrant entre les deux profilés 4 et 5 un embout de blocage 27 conforme à l'invention qui viendra abouter un bord latéral du module 7 ou 12 ou, selon, un bord latéral d'un tronçon 41 d'un tel module destiné, ainsi qu'il vient d'être dit, à approcher au plus près la largeur voulue définie entre les fonds des âmes des deux glissières 6.In order to approach this width as closely as possible, a section 41 of the module 7 or 12 appropriate to the already constructed construction will be placed accordingly, at least near one of the vertical slideways 6, and at each of the two ends the blade 3 thus formed, it will complete the construction by integrating between the two sections 4 and 5 a locking piece 27 according to the invention which will abut a side edge of the module 7 or 12 or, according to a side edge of a section 41 of such a module intended, as we have just said, to approach as close as possible the desired width defined between the bottoms of the souls of the two slides 6.

Afin d'obtenir la longueur de lames idéale, chaque embout de blocage est prévu sécable.In order to obtain the ideal blade length, each locking tip is provided to be scored.

A cette fin, chaque embout de blocage 27 se compose d'un socle 28 dont la largeur est sensiblement égale à celle des profilés 4 et 5 et dont la hauteur est sensiblement égale à la distance D séparant les centres des deux arrondis complémentaires, respectivement supérieur 29 et inférieur 30, des profilés 4 et 5, lesquels arrondis, ainsi qu'il est visible aux Figures 25 et 26, sont complémentaires dans le but de constituer les moyens de verrouillage haut et bas des deux profilés montés sur une même lame 3.To this end, each locking end 27 consists of a base 28 whose width is substantially equal to that of the profiles 4 and 5 and whose height is substantially equal to the distance D separating the centers of the two complementary roundings, respectively greater 29 and lower 30, profiles 4 and 5, which rounded, as it is visible to the Figures 25 and 26 , are complementary in order to constitute the high and low locking means of the two sections mounted on the same blade 3.

Le socle 28 de l'embout 27 est prolongé d'une âme 31 qui lui est perpendiculaire et dont la section est sensiblement identique à celle des modules 7 ou 12.The base 28 of the tip 27 is extended by a core 31 which is perpendicular to it and whose section is substantially identical to that of the modules 7 or 12.

L'âme 31 est prolongée en parties haute et basse d'un retour orthogonal, respectivement 32 et 33, qui s'étend de part et d'autre de l'âme, qui est plus épais que les ailes haute 20 et basse 21 des modules 7 ou 12, et qui coulisse donc à force dans le rail de chaque profilé.The core 31 is extended in the upper and lower parts of an orthogonal return, respectively 32 and 33, which extends on either side of the core, which is thicker than the upper and lower wings 20 and 21 modules 7 or 12, and which slides forcibly in the rail of each profile.

L'âme 31 de l'embout de blocage 27, en ce y compris les retours 32 et 33, comporte en outre à son extrémité libre une pluralité de fentes verticales 34 dont le but est de faciliter la découpe d'une partie de l'âme 31 et la mise parfaite à longueur de ladite âme et desdits retours afin que leur about 35 soit au contact du module extrémal de la lame 3 dont il constitue la terminaison ou, selon, soit au contact du tronçon de module 41 terminant la lame.The core 31 of the locking piece 27, including the returns 32 and 33, further comprises at its free end a plurality of vertical slots 34 whose purpose is to facilitate the cutting of a portion of the soul 31 and the perfect setting to length of said core and said returns so that their end 35 is in contact with the extremal module of the blade 3 which it is the termination or, according to or in contact with the module section 41 ending the blade.

Pour sa fixation au rideau, le socle 28 de chaque embout de blocage 27 est percé de deux orifices 36 traversants au droit des gorges des rails 22, 23 des deux profilés 4, 5 montés sur une même lame 3 et chaque orifice traversant 36 reçoit une vis 40 dont la tige filetée vient se visser en partie centrale du retour orthogonal 32, 33 monté à force à coulissement dans un rail 22, 23.For attachment to the curtain, the base 28 of each locking piece 27 is pierced with two orifices 36 through the grooves of the rails 22, 23 of the two sections 4, 5 mounted on the same blade 3 and each through hole 36 receives a screw 40 whose threaded rod is screwed into the central portion of the orthogonal return 32, 33 slidably mounted in a rail 22, 23.

Chacun des deux retours 32, 33 de l'âme 31 de chaque embout de blocage 27 présente sur sa face externe une rainure longitudinale 37 qui reçoit la tige filetée de la vis 40, et ce afin de faire en sorte que le filet de ladite vis, après avoir coopéré avec la matière du socle 28 de l'embout 27, coopère avec le fond de ladite rainure 37 et avec le fond du rail 22, 23 du profilé 4, 5.Each of the two returns 32, 33 of the core 31 of each locking tip 27 has on its outer face a longitudinal groove 37 which receives the threaded rod of the screw 40, and to ensure that the thread of said screw , after cooperating with the material of the base 28 of the tip 27, cooperates with the bottom of said groove 37 and with the bottom of the rail 22, 23 of the profile 4, 5.

De préférence, la rainure longitudinale 37 s'étend depuis la base 38 du socle 28 de l'embout de blocage 27 jusqu'à la première fente verticale 34.Preferably, the longitudinal groove 37 extends from the base 38 of the base 28 of the locking tip 27 to the first vertical slot 34.

Ainsi qu'il est visible sur les Figures 14 à 18, chaque fente verticale 34 est pratiquée dans l'âme 31 et dans les retours 32, 33 de l'embout 27 de sorte à laisser seulement quelques parties 39 de la matière de l'âme 31, lesdites parties de matière étant espacées et au surplus d'épaisseur réduite.As it is visible on Figures 14 to 18 , each vertical slot 34 is made in the core 31 and in the returns 32, 33 of the tip 27 so as to leave only a few portions 39 of the material of the core 31, said portions of material being spaced apart and in addition of reduced thickness.

On comprend que ces prédécoupes effectuées dans l'âme 31 et dans les retours 32, 33 facilitent grandement l'arrachage d'une, de deux ou de trois parties de l'extrémité de l'embout 27, ainsi qu'il a été donné à titre d'exemple sur les Figures 14 à 18.It is understood that these precuts made in the core 31 and in the returns 32, 33 greatly facilitate the tearing of one, two or three parts of the end of the tip 27, as it was given for example on Figures 14 to 18 .

On comprend également que, sauf dans le cas où il n'y a pas d'utilité à réduire la longueur d'un embout 27, l'about 35 dudit embout est alors constitué par seulement quelques parties de la matière de son âme, deux dans l'exemple représenté à la Figure 17 et à la Figure 28 après découpe schématisée par la flèche A à la Figure 16.It is also understood that, except in the case where there is no use in reducing the length of a tip 27, the tip 35 of said tip is then constituted by only a few parts of the material of his soul, two in the example shown in Figure 17 and at the Figure 28 after cutting schematized by the arrow A to the Figure 16 .

Ainsi qu'il a été représenté sur les Figures 27 et 28, le rideau constitué de la manière décrite ci-dessus est, de façon connue en soi, introduit à chacune de ses deux extrémités dans une glissière latérale verticale 6 constituée sous la forme d'un profilé en U dont l'âme 42 est fixée à la menuiserie et dont les deux ailes 43 encadrent le rideau. L'intérieur de l'extrémité de chaque aile 43 présente avantageusement un logement 44 qui reçoit un joint en caoutchouc 45 destiné à protéger le rideau. Afin de limiter les débattements latéraux du rideau, on peut prévoir légèrement en avant du fond de l'âme 42 de la glissière 6 deux épaulements 46, lesquels épaulements seront alors espacés l'un de l'autre d'une distance suffisante pour permettre le passage des diverses vis de fixation de la glissière 6 dans la menuiserie - mur ou cadre - qui supporte ladite glissière.As he was represented on Figures 27 and 28 the curtain constituted in the manner described above is, in a manner known per se, introduced at each of its two ends into a vertical lateral slide 6 constituted in the form of a U-shaped section whose core 42 is fixed to joinery and whose two wings 43 frame the curtain. The inside of the end of each wing 43 advantageously has a housing 44 which receives a rubber seal 45 for protecting the curtain. In order to limit the lateral deflections of the curtain, two shoulders 46 may be provided slightly in front of the bottom of the web 42 of the slideway 6, which shoulders are then spaced from each other by a sufficient distance to allow the passage of the various fixing screws of the slide 6 in the joinery - wall or frame - which supports said slide.

Enfin, toujours de façon connue en soi, la lame 3 la plus basse du rideau, en l'occurrence le profilé bas 5 de cette lame, est prolongé en étant articulé sur une lame finale 47 en aluminium extrudé qui est dotée en partie haute d'un moyen de verrouillage identique à celui d'un profilé supérieur 4, c'est-à-dire comportant un arrondi 29, et qui est dotée en partie basse d'un rail 48 apte à recevoir un joint d'étanchéité 49 (voir Figures 2 à 4).Finally, still in a manner known per se, the lowest blade 3 of the curtain, in this case the low profile 5 of this blade, is extended by being articulated on a final blade 47 of extruded aluminum which is provided in the upper part of the blade. locking means identical to that of an upper profile 4, that is to say having a rounded portion 29, and which is provided at the bottom with a rail 48 adapted to receive a seal 49 (see FIG. Figures 2 to 4 ).

Cette lame finale 47 est pourvue en outre d'un organe permettant son verrouillage en partie basse de la vitrine ou de la devanture du magasin à protéger.This final blade 47 is further provided with a member allowing its locking in the lower part of the shop window or the storefront to be protected.

Les modules 7 et 12 et les tronçons 41 de tels modules sont en polycarbonate et sont fabriqués par injection.The modules 7 and 12 and the sections 41 of such modules are made of polycarbonate and are manufactured by injection.

Les embouts de blocage 27 sont soit en polycarbonate, soit métalliques, par exemple en acier.The locking caps 27 are either polycarbonate or metal, for example steel.

Les profilés 4 et 5 sont de préférence en aluminium et les glissières latérales verticales 6 sont métalliques, soit en aluminium, soit en acier galvanisé.The profiles 4 and 5 are preferably aluminum and the vertical side rails 6 are metallic, either aluminum or galvanized steel.

Dans la constitution du rideau, les modules 7 ou 12 sont soit alignés les uns au dessus des autres, soit et de préférence, dans le souci d'une meilleure esthétique, disposés en quinconce ainsi qu'il a été représenté à la Figure 1.In the constitution of the curtain, the modules 7 or 12 are either aligned one above the other, or, preferably, for the sake of a better aesthetic, arranged in staggered rows as has been shown in FIG. Figure 1 .

  2. Transparent safety curtain (1) according to claim 1, characterised in that the modules (7) are fitted together so as to simply overlap.
  3. Transparent safety curtain (1) according to claim 2, characterised in that the modules (7) comprise on each of their vertical side edges (9, 10) a Z-shaped projection (11), the end flange of this projection (11) being offset relative to the core (8) of the module (7) while being parallel to said core, and the plane of the inner surface (11') of said end flange coinciding with the plane of the surface (11 ") of the core in whose direction the projection is offset.
  4. Transparent safety curtain (1) according to claim 3, characterised in that the Z-shaped projections (11) formed along the two side edges (9, 10) of each module (7) are of reverse orientation such that the inner surface (11') of each end flange is in contact with the surface (11 ") of the core (8) of an adjacent module.
  5. Transparent safety curtain (1) according to claim 1, characterised in that the modules (12) are force-fitted together.
  6. Transparent safety curtain (1) according to any one of claims 1 to 5, characterised in that the modules (7, 12) have a width of several tens of centimetres, preferably of the order of 30 centimetres.
  7. Transparent safety curtain (1) according to any one of claims 5 and 6, characterised in that the force-fitting of the two modules (12) is achieved by the locking of a hook (16), formed along the vertical edge (13, 14) of each module, in a mating vertical channel (19) formed in the core (15) close to the vertical edge (13, 14) of the other module, slightly recessed from its hook (16).
  8. Transparent safety curtain (1) according to claim 7, characterised in that the two hooks (16) formed along the two vertical edges (13, 14) of each module (12) are of reverse orientations, and one of the two vertical channels (19) is formed in one surface (18) and the other is formed in the other surface (18) of the core (15) of said module (12).
