Abstract

The door opening mechanism, comprising vertical and horizontal rails (3), a drive motor, straps (17), pulleys and rollers that move along the rails, has an auxiliary drive for the initial opening phase comprising an endless screw (7) and a nut (9) connected detachably to the door panel. The screw is set parallel to a horizontal rail (3) and has a stop to limit the travel of the nut, which is connected to the door by a bar (10) and a retaining element (11) with a hook (16) that disengages automatically from the bar when the nut reaches the stop.

Description

Les portes de garage basculantes, en position verticale fermée et en position horizontale ouverte, nécessitent un effort important dans la phase d'ouverture. En effet, la porte étant verticale, et le haut de la porte devant être déplacé horizontalement, il est nécessaire de recourir à des moteurs puissants, donc coûteux, consommateurs d'électricité, entretien, maintenance, ...Tilting garage doors, in the closed vertical position and in horizontal open position, require significant effort in the phase opening. Indeed, the door being vertical, and the top of the door in front be moved horizontally, it is necessary to use motors powerful, therefore expensive, electricity consumers, maintenance, maintenance, ...

La difficulté est d'autant plus grande et l'effort d'autant plus important que l'axe de rotation, correspondant à l'extrémité de la sangle -attachée à la porte, et tirant vers le haut, est décalé vers l'intérieur du garage. Une traction verticale tend en théorie à repousser le haut de la porte selon un mouvement horizontal vers l'extérieur, c'est-à-dire opposé au mouvement souhaité, à savoir vers l'intérieur du garage.The difficulty is all the greater and the effort all the more important as the axis of rotation, corresponding to the end of the strap -attached to the door, and pulling up, is offset towards the interior of the garage. A vertical traction in theory tends to push back the top of the door according to a horizontal outward movement, i.e. opposite to movement desired, namely towards the interior of the garage.

Des solutions connues ont été proposées.Known solutions have been proposed.

On sait que ces portes basculantes sont montées sur des galets, par leur partie supérieure, se déplaçant sur un rail (ou une glissière) horizontal de chaque côté de la porte.We know that these overhead doors are mounted on rollers, by their upper part, moving on a horizontal rail (or slide) of each side of the door.

La première solution connue pour résoudre le problème ci-dessus consiste à courber l'extrémité du rail, du côté de la porte, ce qui donne une composante horizontale permettant d'amorcer le démarrage dans cette phase initiale de déplacement de la porte. The first known solution to solve the above problem consists in bending the end of the rail, on the side of the door, which gives a horizontal component allowing to start up in this initial phase of moving the door.

Cependant, cette solution présente l'inconvénient que le poids du panneau n'est plus supporté totalement par le galet ni par le rail, ce qui implique une reprise du poids par le mécanisme d'entraínement (sangles et autres).However, this solution has the disadvantage that the weight of the panel is no longer fully supported by the roller or the rail, which involves weight recovery by the drive mechanism (straps and others).

On a tenté de remédier à ces inconvénients selon cette solution connue en augmentant le couple du moteur, et/ou en prévoyant des poids de compensation, ce qui ajoute des désavantages supplémentaires en terme de coût, maintenance, montage, encombrement.We tried to remedy these drawbacks using this known solution by increasing the engine torque, and / or by providing weights of compensation, which adds additional disadvantages in term cost, maintenance, assembly, size.

Une deuxième solution connue pour tenter de remédier aux problèmes ci-dessus a été de proposer un mécanisme auxiliaire, à doigt, associé à un deuxième moteur, distinct du moteur d'entraínement de la porte.A second known solution to try to remedy the above problems was to propose an auxiliary mechanism, with finger, associated with a second motor, separate from the door drive motor.

L'inconvénient majeur de cette solution connue résulte de la nécessité de prévoir deux moteurs, avec le coût en montage, achat, et maintenance que cela représente, et la présence d'un ensemble mécanique relativement fragile.The major drawback of this known solution results from the need to provide two motors, with the cost of assembly, purchase, and maintenance that this represents, and the presence of a mechanical assembly relatively fragile.

La présente invention se propose de remédier à ces inconvénients et de résoudre le problème ci-dessus en réalisant un dispositif permettant, de manière simple, peu coûteuse et fiable, d'aider au déplacement de la porte dans la phase initiale d'ouverture.The present invention proposes to remedy these drawbacks and to solve the above problem by making a device allowing, simple, inexpensive and reliable way to help move the door in the initial opening phase.

Afin de faciliter le démarrage de l'ouverture d'une porte basculante, la présente invention concerne un dispositif d'ouverture d'une porte basculante constituée d'un vantail et de deux rails longitudinaux horizontaux et de deux rails longitudinaux verticaux, l'ouverture du vantail étant réalisée à l'aide de moyens moteurs et de moyens d'ouverture, constitués d'un ensemble de sangles, de poulies et de roulettes aptes à se déplacer dans les rails correspondants, le dispositif étant caractérisé en ce qu'il comporte des moyens auxiliaires d'entraínement du vantail lors de la phase d'ouverture de la porte, les moyens auxiliaires étant désolidarisables.To make it easier to start opening a tilting door, the present invention relates to a door opening device tilting consisting of a leaf and two longitudinal rails horizontal and two vertical longitudinal rails, the leaf opening being carried out using motor means and opening means, made up of a set of straps, pulleys and castors suitable for move in the corresponding rails, the device being characterized in that it includes auxiliary means for driving the leaf during the door opening phase, the auxiliary means being detachable.

Plus particulièrement, les moyens auxiliaires sont constitués d'une vis sans fin pourvue d'un écrou relié de manière amovible au vantail, la vis sans fin étant disposée parallèlement à un rail horizontal et présentant une butée de l'écrou.More particularly, the auxiliary means consist of a screw endless provided with a nut removably connected to the leaf, the screw endless being arranged parallel to a horizontal rail and having a nut stopper.

Afin de solidariser simplement l'écrou au vantail, l'écrou est relié au vantail par un doigt, disposé sur l'écrou et apte à coopérer avec des moyens de retenue disposés sur le vantail, les moyens de retenue étant constitués d'un crochet apte à coopérer avec le doigt de l'écrou.In order to simply secure the nut to the leaf, the nut is connected to the leaf by a finger, disposed on the nut and able to cooperate with means of retainers arranged on the leaf, the retaining means being constituted a hook able to cooperate with the finger of the nut.

De préférence, lesdits moyens de retenue se désolidarisent du doigt de l'écrou quand l'écrou entre en contact avec la butée.Preferably, said retaining means are detached from the finger the nut when the nut comes into contact with the stop.

Avantageusement, la vis sans fin est entraínée par un arbre moteur solidaire des moyens moteurs, l'arbre moteur étant rendu solidaire des moyens d'ouverture quand l'écrou entre en contact avec la butée.Advantageously, the worm is driven by a motor shaft secured to the drive means, the drive shaft being secured to the opening means when the nut comes into contact with the stop.

De manière avantageuse, les moyens d'ouverture sont constitués d'au moins deux sangles, d'un pignon principal apte à entraíner deux poulies à engrenage aptes à déplacer le vantail quand l'écrou entre en contact avec la butée.Advantageously, the opening means consist of at least at least two straps, a main pinion capable of driving two pulleys gear capable of moving the leaf when the nut comes into contact with stop.

Avantageusement, l'arbre moteur est fixé sur le pignon principal qui entraíne les poulies à engrenage quand l'écrou entre en contact avec la butée. Advantageously, the drive shaft is fixed on the main pinion which drives the gear pulleys when the nut comes into contact with the stop.

Afin d'obtenir un freinage de la porte, lors de sa phase de fermeture, le crochet du vantail coopère avec le doigt de l'écrou et la rotation de la vis sans fin entraíne le déplacement dudit écrou vers sa position initiale.In order to obtain braking of the door, during its closing phase, the leaf hook cooperates with the finger of the nut and the rotation of the screw endlessly causes said nut to move to its initial position.

De manière avantageuse, le pignon principal est constitué d'une série d'anneaux concentriques présentant intérieurement des butées et doigts correspondants, la série d'anneaux ainsi constituée étant apte à entraíner les poulies quand l'écrou entre en contact avec la butée.Advantageously, the main gear consists of a series concentric rings internally having stops and fingers corresponding, the series of rings thus formed being able to drive the pulleys when the nut comes into contact with the stop.

Afin de permettre une manipulation aisée de la porte, chacune des poulies à engrenage est liée à une sangle, elle-même reliée à un système de contrepoids.In order to allow easy handling of the door, each of the pulleys gear is linked to a strap, itself connected to a system of counterweight.

Le doigt 10 est fixé sur l'écrou 9 selon tout moyen connu (vis, écrou... ), et est constitué d'une tige métallique à section circulaire, coudée.The finger 10 is fixed to the nut 9 according to any known means (screw, nut ...), and consists of a metal rod with circular cross-section, bent.

Le doigt 10 présente une première partie droite proximale 10a fixée sur l'écrou 9, puis une seconde partie droite intermédiaire 10b perpendiculaire à la première partie proximale 10a, et finalement une troisième partie droite distale 10c sensiblement perpendiculaire à la seconde partie intermédiaire 10b, et donc sensiblement parallèle à la première partie proximale 10a.The finger 10 has a first proximal straight part 10a fixed on the nut 9, then a second intermediate straight part 10b perpendicular to the first proximal part 10a, and finally a third part distal line 10c substantially perpendicular to the second part intermediate 10b, and therefore substantially parallel to the first part proximal 10a.

Dans sa position initiale (figure 2), l'écrou 9 est associé au vantail 2 par un crochet 16 disposé sur le bloc pyramidal 12 et coopérant avec le doigt 10.In its initial position (Figure 2), the nut 9 is associated with the leaf 2 by a hook 16 disposed on the pyramid block 12 and cooperating with the finger 10.

Plus précisément, le doigt 10 vient en prise avec le crochet 16 du vantail, au niveau de la partie distale 10c du doigt 10.More specifically, the finger 10 engages with the hook 16 of the leaf, at the distal part 10c of the finger 10.

Les moyens d'ouverture 5, disposés de manière connue dans le rail vertical 4, présentent un ensemble d'au moins deux sangles 17, chacune s'enroulant autour d'une poulie à engrenage 14, 15, de manière à déplacer le vantail 2 quand les moyens moteurs 6 fonctionnent, à l'aide d'un système de contrepoids (non représenté mais connu en soi).The opening means 5, arranged in a known manner in the rail vertical 4, have a set of at least two straps 17, each winding around a gear pulley 14, 15, so that move the leaf 2 when the driving means 6 are operating, using a counterweight system (not shown but known per se).

Le bloc pyramidal 12 présente également un organe de glissement 18 du vantail 2 dans le rail horizontal 3, de type connu en soi.The pyramidal block 12 also has a sliding member 18 of the leaf 2 in the horizontal rail 3, of a type known per se.

La figure 3 représente le même dispositif que celui de la figure 2 mais dans une position intermédiaire, c'est-à-dire quand le vantail 2 est légèrement ouvert.Figure 3 shows the same device as that of Figure 2 but in an intermediate position, i.e. when leaf 2 is slightly open.

Lors de la phase d'ouverture, les moyens moteurs 6 entraínent l'arbre moteur 22 qui entraíne le pignon principal 13, et la vis sans fin 7 qui lui sont associés.During the opening phase, the motor means 6 drive the shaft motor 22 which drives the main gear 13, and the worm 7 which are associated.

Le mouvement de rotation de la vis sans fin 7 entraíne alors le déplacement de l'écrou 9 en direction de la butée 8A (en éloignement des moyens d'ouverture 5). The rotational movement of the worm 7 then causes the displacement of the nut 9 in the direction of the stop 8A (away from the opening means 5).

La partie distale 10c du doigt 10 entraíne alors l'ouverture du vantail 2 de par sa coopération avec le crochet 16 disposé sur le vantail.The distal part 10c of the finger 10 then causes the opening of the leaf 2 of by its cooperation with the hook 16 disposed on the leaf.

Le dispositif selon l'invention permet de créer une force horizontale appropriée pour déplacer le vantail 2.The device according to the invention makes it possible to create a horizontal force suitable for moving the leaf 2.

Lors de la phase d'ouverture, c'est-à-dire, quand l'écrou 9 se déplace sur la vis sans fin 7 en direction de la butée 8A, les poulies à engrenage 14, 15 ne sont pas mises en mouvement par le pignon principal 13.During the opening phase, that is to say, when the nut 9 moves on the worm screw 7 in the direction of the stop 8A, the gear pulleys 14, 15 are not set in motion by the main pinion 13.

En effet, durant cette phase, l'arbre moteur 22 entraíne la vis sans fin 7 seulement, mais pas le pignon principal 13, grâce à un mécanisme débrayable décrit ultérieurement.Indeed, during this phase, the motor shaft 22 drives the worm 7 only, but not the main gear 13, thanks to a mechanism disengageable described later.

Ainsi, l'ouverture de la porte basculante 1 est uniquement réalisée par les moyens moteurs 6 et l'écrou 9. Les efforts d'ouverture ne sont pas subis par l'ensemble des sangles 17.Thus, the opening of the tilting door 1 is only carried out by the motor means 6 and the nut 9. The opening forces are not subjected by the set of straps 17.

La figure 4 représente plus précisément une vue en perspective de l'orgne de glissement 18 et de la butée 8A.Figure 4 shows more precisely a perspective view of the organ sliding 18 and the stop 8A.

L'organe de glissement 18 est pourvu d'une plaque rectangulaire 19 reliant le bloc pyramidal 12 à une roulette 20 apte à se déplacer dans une glissière 21 située dans le rail horizontal 3.The sliding member 18 is provided with a rectangular plate 19 connecting the pyramid block 12 to a caster 20 capable of moving in a slide 21 located in the horizontal rail 3.

Les figures 5 et 6 représentent l'écrou 9 dans sa position finale, c'est-à-dire en contact avec la butée 8A.Figures 5 and 6 show the nut 9 in its final position, that is to say in contact with the stop 8A.

Quand l'écrou 9 entre en contact avec la butée 8A, le pignon principal 13 est conçu de telle manière qu'il puisse alors entraíner les poulies à engrenage 14, 15 et ainsi l'ensemble de sangles 17, ce qui permet le déplacement du vantail 2.When the nut 9 comes into contact with the stop 8A, the main pinion 13 is designed in such a way that it can then drive the pulleys to gear 14, 15 and thus the set of straps 17, which allows the leaf movement 2.

Le crochet 16 (solidaire du vantail) est conçu de telle sorte qu'il puisse, à la fin de la phase d'ouverture, se désolidariser du doigt 10 (solidaire de l'écrou) quand l'écrou 9 porte contre la butée 8A.The hook 16 (integral with the leaf) is designed so that it can, at at the end of the opening phase, detach from finger 10 (secured to the nut) when the nut 9 bears against the stop 8A.

La vis sans fin 7 comporte une gorge circulaire 7A à son extrémité distale de manière que, lorsque l'écrou 9 est en contact avec la butée 8A, il reste associé à ladite gorge 7A, dans laquelle il tourne sans déplacement linéaire. L'écrou 9 est donc dans un état stationnaire, quelque soit le sens de rotation de la vis sans fin 7.The worm 7 has a circular groove 7A at its distal end so that when the nut 9 is in contact with the stop 8A, there remains associated with said groove 7A, in which it rotates without displacement linear. The nut 9 is therefore in a stationary state, whatever the direction rotation of the auger 7.

La figure 6 représente ainsi le dispositif selon l'invention quand le doigt 10 est désolidarisé du crochet 16 du vantail.FIG. 6 thus represents the device according to the invention when the finger 10 is detached from the hook 16 of the leaf.

L'écrou 9 porte contre la butée 8A jusqu'à ce que la porte basculante 1 soit complètement ouverte.The nut 9 bears against the stop 8A until the hinged door 1 is completely open.

Lors de la phase de fermeture, le déplacement du vantail 2 est réalisé uniquement à l'aide de l'ensemble constitué du pignon principal 13, des poulies à engrenage 14, 15 et des sangles 17 reliées à un système de contrepoids.During the closing phase, the leaf 2 is moved only using the assembly consisting of the main pinion 13, gear pulleys 14, 15 and straps 17 connected to a system of counterweight.

Lors de la phase de fermeture, quand le vantail 2, et plus précisément le crochet 16 coopère de nouveau avec le doigt 10, l'écrou 9 est dégagé de la gorge 7A, sur laquelle il était stationnaire, et s'engage de nouveau sur les filets de la vis sans fin 7 qui, de par sa rotation, emmène l'écrou 9 vers sa position initiale. During the closing phase, when the leaf 2, and more precisely the hook 16 cooperates again with finger 10, nut 9 is released from groove 7A, on which it was stationary, and again engages on the threads of the worm 7 which, by its rotation, takes the nut 9 towards its initial position.

De manière plus précise, lors de la fermeture de la porte 1, qui est horizontale, les moyens moteurs 6 sont actionnés et l'arbre moteur 22, donc la vis sans fin 7, exécute cinq tours sur elle-même sans qu'il y ait entraínement des poulies à engrenage 14, 15.More precisely, when the door 1 is closed, which is horizontal, the motor means 6 are actuated and the motor shaft 22, so the worm 7, performs five turns on itself without there being drive gear pulleys 14, 15.

La porte 1 n'est entraínée qu'après rotation de cinq tours sur elle-même de la vis sans fin 7.Door 1 is only driven after rotation of five turns on itself of the auger 7.

Après ces cinq tours, les poulies à engrenage 14, 15 sont entraínées par le pignon principal 13, et le vantail 2 se déplace vers sa position verticale formée initiale, grâce à l'ensemble de sangles 17 et au contrepoids.After these five turns, the gear pulleys 14, 15 are driven by the main pinion 13, and the leaf 2 moves to its vertical position initial formed, thanks to the set of straps 17 and to the counterweight.

Dans la dernière partie de la course de fermeture de la porte 1, le crochet 16 se solidarise de nouveau avec le doigt 10 de l'écrou 9 et entraíne le déplacement de ce dernier. La vis sans fin 7 entraíne le vantail 2 à une vitesse de déplacement inférieure.In the last part of the door 1 closing stroke, the hook 16 is joined again with the finger 10 of the nut 9 and causes the displacement of the latter. The worm 7 drives the leaf 2 to one lower travel speed.

En effet, le déplacement de l'écrou 9, lors de la phase de fermeture, sur la vis sans fin 7 permet de freiner le retour de la porte basculante 1 et permet d'éviter une fermeture trop rapide de la porte basculante 1.Indeed, the displacement of the nut 9, during the closing phase, on the worm screw 7 slows the return of the overhead door 1 and prevents over-closing of the overhead door 1.

La figure 7 représente de dessus les moyens d'ouverture 5, et plus précisément le pignon principal 13 et les deux poulies à engrenage 14, 15.Figure 7 shows from above the opening means 5, and more precisely the main pinion 13 and the two gear pulleys 14, 15.

Le pignon principal 13 est fixé sur l'arbre moteur 22, qui est fixé par une extrémité à la vis sans fin 7 et par l'autre extrémité aux moyens moteurs 6 (non représentés).The main pinion 13 is fixed on the motor shaft 22, which is fixed by a end to the worm 7 and the other end to the motor means 6 (not shown).

Le pignon principal 13 est conçu de telle manière que, lors de la phase d'ouverture, c'est-à-dire lors du déplacement de l'écrou 9 sur la vis sans fin 7 de sa position initiale (figures 1 et 2) à sa position en butée (figure 4), il n'entraíne pas la rotation des poulies à engrenage 14, 15 et donc le déplacement des sangles 17.The main pinion 13 is designed in such a way that, during the phase opening, that is to say when moving the nut 9 on the screw without end 7 from its initial position (FIGS. 1 and 2) to its abutment position (FIG. 4), it does not cause the rotation of the gear pulleys 14, 15 and therefore the moving the straps 17.

Le pignon principal 13 coopère avec les poulies à engrenage 14, 15 uniquement quand l'écrou 9 porte contre la butée 8A.The main pinion 13 cooperates with the gear pulleys 14, 15 only when the nut 9 bears against the stop 8A.

Lors de la phase de fermeture, le pignon principal 13 est conçu de telle manière qu'il entraíne la rotation des poulies à engrenage 14, 15, quand la vis sans fin 7 a effectué cinq tours sur elle-même sans pour autant entraíner un déplacement du vantail 2 et donc de l'écrou 9.During the closing phase, the main pinion 13 is designed in such a way so that it causes the rotation of the gear pulleys 14, 15, when the worm 7 made five turns on itself without necessarily cause movement of the leaf 2 and therefore of the nut 9.

Le pignon principal 13 peut être réalisé à l'aide d'une série d'anneaux cylindriques concentriques présentant des butées et des doigts correspondants (figure 8).The main pinion 13 can be produced using a series of rings concentric cylindrical with stops and fingers correspondents (figure 8).

Ainsi, lors de la rotation de l'arbre moteur, un premier anneau est mis en rotation. Après avoir parcouru un angle prédéterminé mais inférieur à 360°, le premier anneau cylindrique entraíne, grâce à sa butée intérieure, un second anneau cylindrique présentant un doigt intérieur coopérant avec la butée intérieure du premier anneau.Thus, during the rotation of the motor shaft, a first ring is put in rotation. After traveling a predetermined angle but less than 360 °, the first cylindrical ring drives, thanks to its internal stop, a second cylindrical ring having a cooperating inner finger with the inner stop of the first ring.

Le second anneau présente également une butée intérieure lui permettant de coopérer avec le doigt intérieur du troisième anneau, et ainsi de suite jusqu'au dernier anneau comportant un engrenage apte à coopérer avec les engrenages des poulies à engrenage 14, 15.The second ring also has an internal stop allowing it to cooperate with the inner finger of the third ring, and so on up to the last ring comprising a gear capable of cooperating with the gears of the gear pulleys 14, 15.

Le pignon principal 13 est ainsi constitué d'un nombre d'anneaux suffisants présentant intérieurement des butées et doigts correspondants appropriées pour permettre la solidarisation de l'engrenage du pignon principal 13 avec les poulies à engrenage 14, 15 quand l'écrou 9 entre en contact avec la butée 8A.The main pinion 13 thus consists of a number of rings sufficient internally with stops and corresponding fingers suitable for securing the pinion gear main 13 with gear pulleys 14, 15 when nut 9 enters contact with stop 8A.

Il est courant pour l'homme de l'art de déterminer le nombre d'anneaux et la longueur de leurs butées et doigts correspondants pour réaliser un tel pignon principal 13 ayant les caractéristiques requises.It is common for those skilled in the art to determine the number of rings and the length of their stops and corresponding fingers to achieve such main gear 13 having the required characteristics.

La figure 8 représente un anneau à engrenage 25 présentant intérieurement un doigt 26 apte à coopérer avec une butée intérieure 27 d'un second anneau concentrique 28.FIG. 8 represents a gear ring 25 presenting internally a finger 26 capable of cooperating with an internal stop 27 a second concentric ring 28.
