Description

L'invention se rattache au secteur technique des fermetures d'habitations, locaux à usages privés ou publics, garages et autres utilisant des portes basculantes munies de ressorts d'équilibrage. L'invention concerne un dispositif de verrouillage selon le préambule de la revendication 1.The invention relates to the technical sector of residential closings, premises for private or public use, garages and others using up-and-over doors fitted with balancing springs. The invention relates to a device for locking according to the preamble of claim 1.

Selon l'art antérieur, qui est représenté par exemple par une installation de portes basculantes à ressort fabriquées par le Demandeur, selon les figures 1 et 2 des dessins, l'installation comprend un tablier (1) déplaçable dans un encadrement (2) selon un mouvement d'ouverture-fermeture commandé par tous moyens mécaniques ou électriques appropriés. Le tablier est guidé dans des rails (3) horizontaux par des galets (8) disposés dans la partie supérieure du tablier. Ces galets sont susceptibles de se déplacer le long des rails sous l'effet de poussée du tablier dans une position ouverture ou fermeture obtenue par un moyen de traction pouvant être associé non limitativement à un moyen de motorisation.According to the prior art, which is represented for example by an installation of hinged spring doors manufactured by the Applicant, according to Figures 1 and 2 of the drawings, the installation includes an apron (1) movable in a frame (2) according to an opening-closing movement controlled by any means mechanical or electrical suitable. The deck is guided in rails (3) horizontal by rollers (8) arranged in the upper part of the deck. These rollers are likely to move along the rails under the pushing effect of the apron in an open or closed position obtained by a traction means can be associated without limitation to a motor means.

Les tabliers étant d'un poids important pouvant être de l'ordre de 100 à 200 kg, on utilise régulièrement des ressorts de compensation et d'équilibrage (4). Ces derniers sont fixés à une extrémité (4a) supérieure à un bras latéral (5) et à l'autre extrémité (4b) inférieure au dormant (6) de l'encadrement. Ce bras latéral est monté pivotant par rapport à un axe (7) fixé au dormant à un endroit (5a) éloigné de l'extrémité inférieure à l'aide d'une patte de fixation profilée. L'extrémité avant (5b) du bras est montée solidaire et articulée au tablier dans sa partie basse, tandis que l'extrémité (5c) opposée du bras est agencée pour recevoir une boucle d'accrochage (9) ou similaire d'un ou de plusieurs ressorts du type précité. Les ressorts de traction ont une capacité d'allongement déterminé. Selon la position du tablier, le bras est orienté par rapport à son axe (7) pour assurer la sollicitation plus ou moins importante du ou des ressorts précités.The aprons being of a significant weight which can be of the order of 100 to 200 kg, compensating and balancing springs (4) are regularly used. These the latter are fixed at one end (4a) above a lateral arm (5) and at the other end (4b) lower than the frame (6) of the frame. This arm lateral is pivotally mounted relative to an axis (7) fixed to the frame at a location (5a) distant from the lower end using a profiled fixing lug. The front end (5b) of the arm is mounted integral and articulated to the apron in its lower part, while the opposite end (5c) of the arm is arranged to receive a hooking loop (9) or the like of one or more springs of the type cited above. The tension springs have a determined elongation capacity. According to position of the deck, the arm is oriented relative to its axis (7) to ensure the greater or lesser stress on the above-mentioned spring or springs.

Cette technique est fiable, largement utilisée par de nombreux constructeurs.This technique is reliable, widely used by many manufacturers.

Le problème posé réside néanmoins dans l'absence de toute sécurité en cas de fatigue des ressorts qui peuvent casser après usure. Si l'installation est agencée avec, de chaque côté du tablier, des ressorts multiples associés à chaque bras par un moyen de liaison approprié, la rupture d'un ressort n'est pas dramatique bien que gênante, les autres ressorts pouvant amortir la sollicitation supplémentaire. Il reste néanmoins à procéder à un changement du ressort cassé.The problem posed nevertheless lies in the absence of any security in the event of fatigue of springs which can break after wear. If the installation is arranged with, on each side of the deck, multiple springs associated with each arm by a suitable connection, the rupture of a spring is not dramatic although that annoying, the other springs being able to absorb the additional stress. he however, it remains to change the broken spring.

Par contre, dans le cas de l'utilisation qui est courante d'un ou de deux ressorts latéraux associés à chaque bras, la cassure ou rupture du ressort a des conséquences plus gênantes. Le tablier n'est plus maintenu et les risques d'accident des personnes sont très grands. Il ne faut pas oublier en effet que les effets de cassure interviennent lors des mouvements du tablier et donc en présence de personnes.On the other hand, in the case of the current use of one or two lateral springs associated with each arm, the break or rupture of the spring has more embarrassing consequences. The apron is no longer maintained and the risk of accident people are very tall. It should not be forgotten that the effects of breakage occurs during movements of the apron and therefore in the presence of people.

Il existe sur d'autres types de portes, par exemple du type sectionnelles, des moyens de sécurité pouvant ainsi intervenir en cas de rupture de ressorts. Les moyens ne sont cependant pas directement transposables à la situation présente, la cinématique étant différente.There are other types of doors, for example of the sectional type, safety means thus able to intervene in the event of a rupture of springs. The means are not directly transposable to the present situation, the kinematics being different.

Il a été proposé, dans le brevet allemand 3103042 un dispositif de sécurité pour porte de garage prévoyant sur le montant d'encadrement des plaques semi-discale agencées latéralement sur leur face avec une pluralité de trous constituant des moyens d'ancrage radial d'un doigt solidaire du bras de liaison accouplé au tablier de porte. La répartition des trous est établie régulièrement et en cas de rupture du ressort de compensation le doigt pénètre dans l'un des trous pour être censé assurer un blocage en position du tablier. Le doigt est ainsi sollicité pour un effet de ressort.In German patent 3103042, a safety device has been proposed. for garage door providing for the framing amount of the plates semi-disc arranged laterally on their face with a plurality of holes constituting means for radially anchoring a finger secured to the link arm coupled to the door leaf. The hole distribution is established regularly and in the event of a break in the compensating spring, the finger enters one of the holes to be supposed to ensure a blocking in position of the apron. The finger is thus acted upon for a spring effect.

En pratique, cette solution n'est pas satisfaisante car le poids du tablier provoque un effet de basculement très rapide qui n'offre pas la possibilité au doigt de pénétrer dans un temps extrêmement court dans le trou en regard. Le positionnement du doigt reste aléatoire. Cette solution n'est donc pas satisfaisante.In practice, this solution is not satisfactory because the weight of the deck causes a very rapid tilting effect which does not offer the possibility of the finger to penetrate in an extremely short time in the opposite hole. The finger positioning remains random. This solution is therefore not satisfactory.

Le but recherché selon l'invention était donc de concevoir un dispositif de verrouillage en cours de manoeuvre des portes basculantes à ressorts de compensation qui soit simple, efficace, peu coûteux et particulièrement adapté au problème posé.The aim sought after according to the invention was therefore to design a device for interlocking of spring-loaded up-and-over doors during operation compensation that is simple, effective, inexpensive and particularly suited to problem.

Un autre but recherché selon l'invention était de concevoir un dispositif de sécurité qui soit opérationnel instantanément en cas de rupture de ressort et qui ne puisse être déverrouillé que par l'intervention d'un opérateur.Another aim sought after according to the invention was to design a device for safety which is instantly operational in the event of a spring break and which does not can only be unlocked by the intervention of an operator.

Ces buts et d'autres encore ressortiront bien de la suite de la description.These and other objects will become apparent from the following description.

Ces buts sont atteints par l'adjonction des caractéristiques de la partie caractérisante de la revendication 1.These goals are achieved by adding characteristics of the characterizing part of claim 1.

Selon une autre caractéristique, le moyen-support est profilé en U et reçoit une ossature pivotante constituant le moyen d'ancrage articulé par rapport à un axe disposé entre les ailes du support, ledit moyen d'ancrage présentant, dans sa partie médiane, une fente pour le passage et la retenue de la sangle et, à son extrémité supérieure, un point d'attache d'un ressort de rappel dont l'autre extrémité est fixée sur le support, le moyen d'ancrage étant agencé à son autre extrémité avec une forme en dent, et en ce que le support reçoit, à l'arrière du moyen d'ancrage, un axe fixe constituant un moyen de renvoi de la sangle du moyen d'équilibrage.According to another characteristic, the support medium is U-shaped and receives a pivoting frame constituting the anchoring means articulated with respect to an axis disposed between the wings of the support, said anchoring means having, in its part middle, a slot for the passage and the retention of the strap and, at its end upper, a point of attachment of a return spring whose other end is fixed on the support, the anchoring means being arranged at its other end with a tooth shape, and in that the support receives, at the rear of the anchoring means, a fixed axis constituting a means of returning the strap of the balancing means.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These characteristics and others will become clear from the rest of the description.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative aux figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner to the figures of the drawings.

On a représenté une porte de garage basculante à ressorts d'équilibrage qui comprend un tablier (1) susceptible de basculer par rapport à un dormant (6) d'un encadrement de porte ou équivalent. Le tablier est convenablement guidé dans sa partie supérieure par des galets (8) susceptibles de se déplacer dans des rails de guidage (3) convenablement disposées de manière connue dans le local recevant la porte basculante. Dans sa partie médiane, le tablier est susceptible de recevoir un pivot permettant l'articulation d'un bras de manoeuvre (5) dont une extrémité (5b) est solidaire du tablier dans la partie haute de celui-ci, et l'autre extrémité (5c) est accouplée à un moyen d'équilibrage (10). Ce dernier comprend essentiellement une sangle (10a) associée à un ou des ressorts (10b) dont les extrémités sont fixées par rapport à un point d'appui fixe établi sur le dormant ou au sol.There is shown a tilting garage door with balancing springs which comprises an apron (1) capable of tilting relative to a frame (6) door frame or equivalent. The apron is properly guided in its upper part by rollers (8) capable of moving in rails guide (3) suitably arranged in a known manner in the room receiving the overhead door. In its middle part, the apron is likely to receive a pivot allowing the articulation of an operating arm (5), one end of which (5b) is integral with the deck in the upper part thereof, and the other end (5c) is coupled to a balancing means (10). The latter includes essentially a strap (10a) associated with one or more springs (10b) whose ends are fixed relative to a fixed fulcrum established on the frame or on the ground.

Selon l'invention, le pivot (7) d'articulation du bras (5) est monté sur une forme en chape (12) comprenant deux flasques (12a - 12b) latéraux, et solidaires du dormant par tous moyens appropriés. Cette forme en chape présente des flasques latéraux établis sous forme de deux demi-disques. Un moyen support (13) solidaire en bout du bras pivotant (5) est susceptible de recevoir un moyen d'ancrage pivotant. Avantageusement, ce moyen support est établi à partir d'une structure portante comprenant, d'une part, un prolongement ou l'extrémité (5b) du bras, d'un côté de la chape, et présentant, de l'autre côté de celle-ci, une barre (11) de liaison profilée, l'ensemble traversant l'axe (7) de pivotement du bras et étant relié à l'extrémité par un axe entretoise (16) à position fixe. Ainsi l'extrémité (5b) du bras et la barre (11) entourent les deux flasques (12a - 12b) de la chape. Le moyen support (13) profilé en U est susceptible de recevoir une ossature pivotante (14) constituant le moyen d'ancrage (15) du ressort d'équilibrage et, en cas de rupture de ce dernier, permettant un blocage net et immédiat du tablier. Le moyen support (13) est établi sous forme d'un profilé en U dont les ailes (13a - 13b) sont solidaires fixement du bras (5b) et de la barre (11). L'axe (16) à position fixe constitue un moyen de renvoi de la partie sangle (10a) du moyen d'équilibrage (10). Cette sangle est tissée et est susceptible de se déplacer partiellement sur l'axe (16) en cas de sollicitation. Cette sangle se prolonge à son extrémité libre qui est pendante pour être accouplée à travers un axe de liaison (18) avec le ou les ressorts (10b) d'équilibrage du tablier.According to the invention, the pivot (7) of articulation of the arm (5) is mounted on a screed shape (12) comprising two lateral flanges (12a - 12b), and secured to the frame by any appropriate means. This screed shape presents lateral flanges established in the form of two half-discs. Support medium (13) secured at the end of the pivoting arm (5) is capable of receiving a means swivel anchor. Advantageously, this support means is established from a bearing structure comprising, on the one hand, an extension or end (5b) of the arm, on one side of the yoke, and having, on the other side thereof, a bar (11) of profiled connection, the assembly crossing the pivot axis (7) of the arm and being connected at the end by a spacer pin (16) in a fixed position. So the end (5b) of the arm and the bar (11) surround the two flanges (12a - 12b) of the screed. The U-shaped support means (13) is capable of receiving a pivoting frame (14) constituting the anchoring means (15) of the spring balancing and, in the event of breakage of the latter, allowing a net blocking and immediately of the apron. The support means (13) is established in the form of a U-shaped profile whose wings (13a - 13b) are fixedly secured to the arm (5b) and the bar (11). The fixed position pin (16) constitutes a means of returning the strap part (10a) of the balancing means (10). This strap is woven and is susceptible to partially move on the axis (16) in the event of stress. This strap is extends at its free end which is hanging to be coupled through a connecting pin (18) with the spring or springs (10b) for balancing the deck.

Dans la première réalisation des figures 3 et 4, est prévu, au-delà de l'axe (16) précité, un moyen d'ancrage (19) profilé et articulé sur un axe (20) situé entre les ailes du support (13). Par sa partie supérieure, lé moyen d'ancrage (19) vient en appui sur l'axe fixe (16). Dans sa partie médiane, ce moyen d'ancrage présente une fente (19a) permettant le passage de la sangle (10a) qui est établie en extrémité sous forme de boucle (10c) autorisant l'insertion d'un axe de retenue (21) venant plaquer contre le profil intérieur du moyen d'ancrage. Ce dernier présente à son extrémité supérieure au moins un point d'attache (19b) d'au moins un ressort de rappel (22) dont l'autre extrémité (22a) est fixée sur les ailes latérales du support (13). Le moyen d'ancrage (19) articulé est, à son autre extrémité (19c), profilé directement en forme de dent, ou reçoit une plaquette (23) dentée rapportée, réalisée en matériau traité au carbure ou autre.In the first embodiment of FIGS. 3 and 4, provision is made, beyond the axis (16) above, an anchoring means (19) profiled and articulated on an axis (20) located between the wings of the support (13). By its upper part, the anchoring means (19) comes to bear on the fixed axis (16). In its middle part, this means anchor has a slot (19a) allowing the passage of the strap (10a) which is established at the end in the form of a loop (10c) allowing the insertion of an axis of retainer (21) pressing against the inner profile of the anchoring means. This the latter has at its upper end at least one attachment point (19b) at least one return spring (22), the other end (22a) of which is fixed to the lateral wings of the support (13). The articulated anchoring means (19) is, at its other end (19c), shaped directly in the form of a tooth, or receives a attached toothed plate (23), made of material treated with carbide or other.

En position de non-sollicitation, ledit moyen d'ancrage articulé est relevé, la partie dentelée n'étant pas en contact avec les flasques (12a - 12b) de la chape (12). Cette situation correspond au fonctionnement normal du ressort d'équilibrage (10b) qui est associé à la sangle de liaison (10a) précitée. La fonction de rappel dudit ressort d'équilibrage provoque donc le basculement en retrait du moyen d'ancrage précité, et donc l'extension du ou des ressorts (22). En cas de rupture du ressort d'équilibrage (10b), le moyen d'ancrage précité n'est plus soumis à un effort de retenue, de sorte que, par l'effet de détente du ou des ressorts latéraux (22), la partie dentelée (19c - 23) du moyen d'ancrage est pivotée d'une manière instantanée pour suivre un mouvement ou trajectoire curviligne à la manière d'une griffe pour s'insérer dans l'épaisseur et sur la périphérie des flasques (12a - 12b) de la chape (12). Cela provoque immédiatement par cet ancrage l'arrêt de pivotement du bras (5) basculant et donc la mise en position d'arrêt du tablier. Le couple exercé est suffisamment important, et l'ancrage dans les flasques suffisamment fort pour un blocage net du tablier. Il est alors possible pour l'opérateur de procéder au changement du ressort d'équilibrage (10b) cassé, sur place et en toute sécurité. Lorsque le nouveau ressort d'équilibrage est positionné et en état de fonctionnement, sa force de rétraction est susceptible avec ou sans l'aide d'un effort complémentaire de retirer le moyen d'ancrage des flasques précités de la chape.In the non-stressing position, said articulated anchoring means is raised, the serrated part not in contact with the flanges (12a - 12b) of the yoke (12). This situation corresponds to the normal operation of the spring balancing (10b) which is associated with the aforementioned connecting strap (10a). The return function of said balancing spring therefore causes the tilting removal of the above anchoring means, and therefore the extension of the spring (s) (22). In breakage of the balancing spring (10b), the above-mentioned anchoring means is not no longer subjected to a restraining force, so that, by the relaxing effect of the lateral springs (22), the serrated part (19c - 23) of the anchoring means is instantly rotated to follow a movement or trajectory curvilinear like a claw to fit into the thickness and on the periphery of the flanges (12a - 12b) of the yoke (12). That provokes immediately by this anchoring the pivoting stop of the tilting arm (5) and therefore putting the apron in the stop position. The torque exerted is sufficient important, and the anchoring in the flanges strong enough for a net blockage of the apron. It is then possible for the operator to change the spring balancing (10b) broken, on site and safely. When the new balancing spring is positioned and in working condition, its strength retraction is likely with or without the help of an additional effort to withdraw the means for anchoring the aforementioned flanges of the yoke.

Ce dispositif offre une sécurité totale. La périphérie des flasques est lisse et on obtient ainsi une parfaite tenue et ancrage. Lors du mouvement de pénétration du moyen d'ancrage par sa partie dentée, celle-ci pénètre dans plusieurs millimètres d'épaisseur de la chape.This device offers total security. The periphery of the flanges is smooth and thus obtaining perfect hold and anchoring. During the movement of penetration of the anchoring means by its toothed part, this penetrates into several millimeters thickness of the screed.

Dans la variante de réalisation des figures 6 et 7, les flasques latéraux (12a - 12b) de la chape sont dentelés (12c) en formant crémaillère. Le moyen d'ancrage utilisé précédemment est remplacé par une barrette (24) articulée qui est intégrée dans la boucle d'extrémité de la sangle en débordement de celle-ci. Ladite barrette est perforée en présentant, à une extrémité (24a), un axe de pivotement (25) et à l'autre extrémité (24b) un point d'ancrage d'un ressort de traction (26). Ce dernier est lui-même fixé à son autre extrémité sur un axe ou point d'ancrage établi entre les ailes latérales du support (13). Dans ce cas là, le fonctionnement est identique. En cas de rupture du ressort d'équilibrage (10b), la barrette (24) est sollicitée en rappel par le ressort latéral (26) précité, en l'entraínant ainsi entre des crans formés sur la périphérie des flasques de la chape.In the alternative embodiment of Figures 6 and 7, the side flanges (12a - 12b) of the yoke are serrated (12c) forming a rack. The anchoring means previously used is replaced by an articulated bar (24) which is integrated in the end loop of the strap projecting from it. Said strip is perforated by presenting, at one end (24a), a pivot axis (25) and at the other end (24b) an anchor point for a tension spring (26). The latter is itself fixed at its other end on an axis or anchor point established between the lateral wings of the support (13). In this case, the operation is identical. In the event of a break in the balancing spring (10b), the bar (24) is biased by the aforementioned lateral spring (26), resulting in notches formed on the periphery of the flanges of the yoke.

Dans une autre variante illustrée aux figures 8 et 9, on peut concevoir que le moyen d'ancrage avec les flasques latéraux de la chape est une bague moletée (27) montée en excentration sur un axe (28) disposé entre les ailes latérales du support (13). Cette bague moletée est susceptible, en cas de cassure du ressort d'équilibrage, de venir, par l'effet d'excentration, en butée et en appui contre les flasques de la chape. Ceci est réalisé par le fait que la sangle (10a) est maintenue en tension par un ressort (29) fixé à un point fixe du support (13). Par l'effet de détente, il provoque l'entraínement et la rotation de la bague moletée grâce à un moyen de liaison (30) formant butée.In another variant illustrated in FIGS. 8 and 9, it is conceivable that the anchoring means with the side flanges of the yoke is a knurled ring (27) mounted eccentrically on an axis (28) disposed between the lateral wings of the support (13). This knurled ring is susceptible, in the event of breakage of the spring balancing, to come, by the eccentric effect, in abutment and in support against flanges of the yoke. This is achieved by the fact that the strap (10a) is held in tension by a spring (29) fixed to a fixed point of the support (13). By the effect of trigger, it causes the drive and the rotation of the knurled ring thanks to a connecting means (30) forming a stop.

D'autres variantes équivalentes peuvent être utilisées pour assurer la fonction souhaitée de blocage en position du tablier en cas de rupture du ressort d'équilibrage.Other equivalent variants can be used to ensure the desired function of locking in position of the bulkhead in the event of a spring break balancing.

L'intérêt de la présente invention réside dans la sécurité accrue de ce type de portes basculantes en cas de rupture d'un ressort.The advantage of the present invention lies in the increased safety of this type of tilting doors in the event of a spring break.

Le dispositif selon l'invention est simple à réaliser et d'une grande fiabilité.The device according to the invention is simple to produce and very reliable.
