Description
La présente invention concerne une installation de fermeture ou de protection solaire comportant un ensemble de sécurité.The present invention relates to an installation of closure or sun protection comprising a set of security.
Par installation de fermeture, on entend les portes, portails, volets et matériels équivalents.Closure means doors, gates, shutters and equivalent equipment.
Dans une installation de fermeture ou de protection solaire, il est connu d'utiliser un mécanisme d'enroulement pour la manoeuvre d'un écran, terme générique utilisé ici pour désigner notamment un tablier, une porte ou un volet. L'invention vise plus spécifiquement, mais non exclusivement, une telle installation, dont le mécanisme d'enroulement peut être actionné électriquement, grâce à un moteur.In a closing or protective installation solar, it is known to use a winding mechanism for the operation of a screen, a generic term used here to designate in particular an apron, a door or a shutter. The invention aims more specifically, but not exclusively, such an installation, including the mechanism winding can be operated electrically, thanks to a engine.
Dans cette optique, il est tout d'abord connu d'associer, à ce moteur, des moyens d'arrêt de l'écran précité, en fin de course. Ainsi, il existe des ensembles standards intégrant un moto-réducteur et un dispositif de fin de course, tel que celui décrit dans DE-A-34 20 789.In this perspective, it is first known to associate, with this engine, means of stopping the screen aforementioned, at the end of the race. So, there are sets standards incorporating a geared motor and a limit switch, such as that described in DE-A-34 20 789.
En cas de défaillance du dispositif de fin de course, il est également connu de faire appel à un dispositif complémentaire de fin de course, dite « ultime ». Un tel dispositif constitue un moyen d'arrêt de l'écran, lorsque ce dernier se trouve au-delà de sa ou de ses positions(s) de fin de course. Après la mise en oeuvre de ce dispositif de fin de course ultime, l'installation de fermeture ou de protection solaire ne peut plus être utilisée en l'état.In case of failure of the end-of-stroke device, it is also known to use a device complementary end of race, called "ultimate". Such device constitutes a means of stopping the screen, when the latter is beyond his position (s) end of race. After the implementation of this device end of the race, the closing or sun protection can no longer be used as is.
Ceci étant précisé, il est connu d'intégrer, au sein d'un même ensemble de sécurité, un dispositif de fin de course et un dispositif de fin de course ultime, associés au moteur électrique. Un tel agencement est par exemple conforme à un de ceux commercialisés respectivement par la société GFA sous la référence SI25.10 - SI55.15, par la société GAROG sous la référence DK, ou encore par la société MEZ sous la référence MTZ. That being said, it is known to integrate, within of the same set of security, a device for the end of race and an ultimate end-of-race device, associated to the electric motor. Such an arrangement is for example conform to one of those marketed respectively by the GFA under the reference SI25.10 - SI55.15, by the GAROG under the reference DK, or by the MEZ company under the reference MTZ.
Par ailleurs, il est connu de munir des installations de fermeture ou de protection solaire au moyen de dispositifs de sécurité, dénommés « anti-chute ». Ces derniers sont destinés à empêcher la chute de l'écran sous l'effet de la gravité, dans le cas d'une rupture mécanique intervenant dans la chaíne cinématique de commande de cet écran et/ou dans le cas de casse d'un ressort de compensation.Moreover, it is known to provide facilities closing or sun protection by means of safety devices, called "anti-fall". These last are intended to prevent the fall of the screen under the effect of gravity, in the case of a mechanical break intervening in the kinematic chain control of this screen and / or in the case of breakage of a spring compensation.
Dans cette optique, un interrupteur d'arrêt du moteur électrique est actionné, à la suite de la détection de la rupture d'un ressort de compensation de l'installation, comme cela est connu de EP-A-0 151 427 ou de DE-U-93 10 792. A titre d'alternative, cet interrupteur d'arrêt est actionné à la suite de la détection d'une vitesse de rotation anormale de l'arbre de manoeuvre de l'écran, comme cela est connu par DE-A-199 29 094.With this in mind, an engine stop switch electrical power is activated, following the detection of the rupture of a compensation spring of the installation, as is known from EP-A-0 151 427 or DE-U-93 10 792. Alternatively, this stop switch is actuated following the detection of a speed of abnormal rotation of the maneuvering shaft of the screen, as this is known from DE-A-199 29 094.
Compte tenu de ce qui précède, l'invention se propose de conférer davantage de sécurité aux installations existantes de fermeture ou de protection solaire, qui ne sont pas sécurisées de façon suffisante.In view of the foregoing, the invention proposes to give more security to the facilities existing closure or sun protection, which does not are not secure enough.
En outre, l'invention se propose de réaliser l'amélioration précitée, en préservant dans la mesure du possible l'agencement de ces installations déjà existantes, tout en utilisant de façon optimale les équipements annexes proposés dans le commerce.In addition, the invention proposes to carry out the aforementioned improvement, preserving to the extent possible the arrangement of these already existing installations, while optimally using ancillary equipment offered in the trade.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaítront plus clairement à la lumière de la description qui va suivre de deux modes de réalisation d'une installation de fermeture ou de protection solaire conforme à son principe, donnée uniquement à titre d'exemples non limitatifs et faite en référence aux dessins annexés, dans lesquels :
- les figures 1
et 2 sont des vues, respectivement de face et de côté, illustrant une installation de fermeture ou de protection solaire conforme à l'invention ; - la figure 3 est une vue agrandie de la zone III de la figure 1 ; et
- la figure 4 est une vue agrandie de face, analogue à la figure 3, illustrant une variante de réalisation de l'invention.
- Figures 1 and 2 are views, respectively front and side, illustrating a closure system or solar protection according to the invention;
- Figure 3 is an enlarged view of the area III of Figure 1; and
- Figure 4 is an enlarged front view, similar to Figure 3, illustrating an alternative embodiment of the invention.
L'installation de fermeture ou de protection solaire,
illustrée sur les figures 1 à 3, comprend tout d'abord un
bâti, comportant deux coulisses 2 qui supportent de façon
classique un tube d'enroulement 4. Ce dernier est destiné à
entraíner un écran 6, apte à obturer de façon sélective une
ouverture 8 délimitée sensiblement par les deux coulisses 2
et la partie inférieure du tube 4.The installation of closing or sunscreen,
illustrated in FIGS. 1 to 3, comprises first of all a
built, having two
D'un premier côté longitudinal de ce tube 4, à savoir
d'un premier côté latéral de l'écran, il est prévu un
support 10, sur lequel est monté un ensemble formé d'un
moteur électrique 11 et d'un dispositif 12 de fin de
course. Cet ensemble 11, 12, connu en tant que tel, est par
exemple conforme à celui décrit dans DE-A-34 20 789. Of a first longitudinal side of this
De l'autre côté latéral de l'écran 6, une roue à
galets 14 est montée solidaire d'un arbre principal 16,
destiné à la manoeuvre du tube d'enroulement 4. Cette roue à
galets 14, qui est conforme à l'enseignement de DE-A-199 29
094, est apte à coopérer avec un interrupteur 20 d'arrêt de
l'arbre 16, comme on le verra dans ce qui suit.On the other side of the
Un engrenage 22, venant en prise avec la roue 14 au
niveau d'un épaulement 141 de cette dernière, est solidaire
d'un arbre secondaire 24, réalisé sous forme d'une tige
filetée, qui est reçue dans un boítier 26. Cette tige 24,
qui est parallèle à l'arbre principal 16, tout en étant
décalée par rapport à ce dernier, supporte deux écrous 28
et 28', formant éléments baladeurs.A
Ces derniers ne sont cependant pas solidaires de la
tige 24, ni en rotation ni en translation, étant donné la
présence d'un levier 30, permettant d'immobiliser ces
baladeurs 28 en rotation par rapport au boítier 26. Il est
à remarquer que ce levier 30 est escamotable, selon la
ligne pointillée à la figure 3, de manière à autoriser un
réglage manuel du positionnement relatif de ces baladeurs
28 et de la tige 24.However, they are not in solidarity with the
Il est enfin prévu un second interrupteur 32 d'arrêt
de l'arbre 16, reçu en partie dans le volume intérieur du
boítier 26. Cet interrupteur 32 est disposé axialement
entre les deux baladeurs 28 et 28', de sorte que l'un ou
l'autre de ceux-ci est apte à actionner cet interrupteur,
comme on le verra dans ce qui suit.Finally, a
Il est à noter que la roue à galets 14 se trouve
montée sur un support fixe 34, reposant sur une console 35
solidaire du bâti. De plus, l'engrenage 22 est reçu dans un
alésage 36, ménagé dans ce support 34, alors que le boítier
26 est solidarisé contre les parois d'un logement 38, prévu
dans ce support 34, qui débouche dans l'alésage précité 36,
tout en présentant des dimensions radiales nettement
supérieures à ce dernier.It should be noted that the
L'utilisation de l'installation de fermeture ou de protection solaire, décrite ci-dessus, va maintenant être explicitée en référence aux figures 1 à 3.The use of the closure system or sunscreen, described above, will now be explained with reference to FIGS. 1 to 3.
En fonctionnement normal de cette installation,
l'ensemble 11, 12 assure, d'une part, la motorisation et
donc le déplacement de l'écran 6 et, d'autre part, l'arrêt
de ce dernier dans deux positions de fin de course
prédéterminées. En cas de défaillance des moyens d'arrêt en
fin de course 12, l'arbre principal 16 continue à entraíner
l'écran 6 et, par conséquent, la roue à galets 14 et la
tige filetée 24.In normal operation of this installation,
the
Dans ces conditions, les baladeurs 28 et 28' se
déplacent en translation par rapport à cette tige 24, selon
la double flèche F. A un certain moment, l'un ou l'autre de
ces baladeurs 28 ou 28' actionne donc l'interrupteur 32, ce
qui induit l'arrêt immédiat de l'arbre principal 16. Cette
tige filetée 24, ces baladeurs 28, 28' et cet interrupteur
32 forment donc des moyens complémentaires d'arrêt de fin
de course, dénommés encore moyens de fin de course ultime,
aptes à arrêter l'écran 6 lorsque ce dernier se trouve au-delà
de ses positions normales de fin de course.Under these conditions, the
Par ailleurs, en cas de chute de l'écran 6, due
notamment à une rupture mécanique intervenant dans la
chaíne cinématique qui assure sa commande, la vitesse de
rotation de la roue à galets 14 augmente. Par conséquent,
la roue 14 se bloque, de sorte que celle-ci actionne
l'interrupteur 20, ce qui interrompt l'alimentation du
moteur et conduit à l'arrêt immédiat de l'écran 6.Moreover, in case of a fall of
La figure 4 illustre une variante de réalisation de l'invention. Sur cette figure, les éléments mécaniques analogues à ceux des figures 1 à 3 y sont affectés des mêmes numéros de référence, augmentés de 100. FIG. 4 illustrates a variant embodiment of the invention. In this figure, the mechanical elements similar to those of Figures 1 to 3 are assigned same reference numbers, increased by 100.
Dans cette variante de réalisation, les moyens d'arrêt
de l'écran en fin de course ultime sont dépourvus d'un
interrupteur, tel que celui 32 des figures 1 à 3. Celui-ci
est remplacé par un levier 132, globalement en forme de T.
Ce levier 132, qui est monté pivotant autour d'un axe A
perpendiculaire à la tige filetée 124, comporte deux
branches, dont l'une 1321 s'étend entre les deux baladeurs
128 et 128', et dont l'autre 1322 s'étend au voisinage de
l'interrupteur 120.In this variant embodiment, the means for stopping the screen at the end of the final stroke are devoid of a switch, such as that of FIGS. 1 to 3. This is replaced by a
Ainsi, en service, lors de la défaillance du système
de fin de course classique, l'un des baladeurs 128 ou 128'
vient en contact avec la branche 1321 du levier 132. Ce
dernier pivote alors autour de l'axe A, de sorte que sa
branche 1322 actionne l'interrupteur 120, ce qui interrompt
l'alimentation du moteur et arrête l'arbre d'entraínement
116.Thus, in use, during the failure of the conventional end-of-travel system, one of the
L'invention n'est pas limitée aux exemples décrits et représentés.The invention is not limited to the examples described and represented.
Ainsi, elle peut être mise en oeuvre avec tout autre type de motorisation, notamment tubulaire. En outre, il est possible de faire appel à un autre type de dispositif anti-chute, tirant notamment parti d'une détection de la casse d'un ressort de compensation, comme décrit dans EP-A-0 151 427 ou dans DE-U-93 10 792.So, it can be implemented with any other type of motorization, especially tubular. In addition, it is possible to use another type of anti-fall device, taking advantage in particular of a case detection of a compensation spring, as described in EP-A-0 151 427 or in DE-U-93 10 792.
Il est également possible de faire appel à un autre type d'arrêt de fin de course, notamment à rouleaux comme décrit dans FR-A-2 688 022, ou bien à cames comme décrit dans IT-1 241 960, ou enfin à détection de couple comme décrit dans DE-A-29 517 926.It is also possible to call on another type of end-stop, particularly with rollers described in FR-A-2 688 022, or with cams as described in IT-1 241 960, or finally at torque detection as described in DE-A-29 517 926.
L'invention permet de réaliser les objectifs précédemment mentionnés.The invention makes it possible to achieve the objectives previously mentioned.
En effet, elle confère une sécurité appréciable à l'installation de fermeture ou de protection solaire conforme à son principe. Indeed, it confers appreciable security to the installation of closing or sunscreen in accordance with its principle.
Par ailleurs, la solution apportée par l'invention est d'une modularité remarquable, en ce qui concerne l'utilisation des installations et des équipements annexes déjà existants ou disponibles sur le marché.Moreover, the solution provided by the invention is a remarkable modularity, as far as use of facilities and ancillary equipment already existing or available on the market.
Ainsi, dans le cas d'installations existantes non sécurisées, il y a uniquement lieu d'ajouter le dispositif de fin de course ultime, associé au disposition anti-chute. De ce fait, l'équipement existant reste opérationnel, dans la mesure où aucun de ses composants ne se trouve enlevé ni substitué.Thus, in the case of existing installations not secure, it is only necessary to add the device Ultimate end of stroke, associated with the anti-fall feature. As a result, the existing equipment remains operational, in the extent that none of its components are removed or substituted.
De plus, lorsqu'il s'agit de monter de nouvelles installations, il est possible de proposer la motorisation traditionnelle, éventuellement associée à son dispositif classique de fin de course. Par conséquent, il n'est pas nécessaire de prévoir une motorisation spécifique, de sorte que la gamme existante ne se trouve pas modifiée.Moreover, when it comes to setting up new facilities, it is possible to offer the motorization traditional, possibly associated with its device classic end of race.
