Definitions
- the present invention relates to hinged doors with two leaves, of the type in particular of those which equip cubicles for public telephones, and it is more particularly intended to allow the realization of a security mechanism which is arranged in the first place to ensure the simultaneous angular displacement of the two leaves when only one of them is operated by the user, secondly to allow one of these leaves to be operated while the other remains momentarily immobile as a result of a stop effect which is temporarily exerted on it, this immobilized leaf automatically pivoting in the same direction as the first as soon as the aforementioned effect ceases, and thirdly for operating the automatic return of the two leaves to the closed position.
- each compensating device was formed by a cylinder inside which telescopically slides a rod provided at the end of a head constituent stop for a spring also bearing against the bottom of said cylinder which is crossed by the rod.
- each of the door leaves is angularly linked to a winding member having two superimposed drums with different diameters, and the small diameter drum of one is joined to the large diameter drum of the other, and vice versa, by two funicular elements which are wound on their drums in opposite directions and along the length of each of which are interposed elastically deformable means in tension and compression, advantageously constituted by simple helical springs with non-contiguous turns.
- Fig. 1 is a perspective view showing the upper part of a swing door with two leaves fitted with a safety mechanism according to the invention.
- Fig. 2 and 3 are similar views illustrating the operation of this mechanism.

- the outer edge of each leaf 1 or 2 is provided with a hinge 3 (fig. 1) fixed radially at the end of a vertical shaft or pivot 4, which is suitably supported by the fixed carcass of the cabin. so that you can freely turn on itself.
- the lower edge (not shown) of each of the leaves 1 and 2 is supported by a conventional pivot, oriented along the axis of the corresponding pivot 4.
- each member 5 or 6 is arranged to present two superimposed parts or drums 5 a and 5 b , respectively 6 a and 6 b , established at two different diameters. It will be observed that the vertical arrangement of these drums is reversed on the two members 5 and 6, in the sense that the drum 5 a with small diameter is placed above the drum 5 b of the member 5, while the small drum 6 a is located above the drum 6 b of the same member 6.
- the two members 5 and 6 are angularly linked to one another by two superimposed funicular elements 7 and 8 each of which, oriented horizontally, is constituted by two portions of wire rope joined to each other by a helical spring 7 a , respectively 8 a .
- the free end of each portion of cable is stowed on the periphery of one of the drums of each member 5 and 6, so that the element 7 connects the large drum 5 b to the small drum 6 a , while in a horizontal plane located at a lower level, the element 8 joins the small drum 5 a to the large drum 6 b .

Description
La présente invention est relative aux portes battantes à deux vantaux, du genre notamment de celles qui équipent les cabines pour téléphone public, et elle a plus spécialement pour but de permettre la réalisation d'un mécanisme de sécurité qui est agencé en premier lieu pour assurer le déplacement angulaire simultané des deux vantaux lorsqu'un seul de ceux-ci est manoeuvré par l'utilisateur, en deuxième lieu pour permettre à l'un de ces vantaux d'être manoeuvré alors que l'autre reste momentanément immobile par suite d'un effet de butée qui s'exerce temporairement sur lui, ce vantail immobilisé pivotant automatiquement dans le même sens que le premier dès que l'effet précité cesse, et en troisième lieu pour opérer le rappel automatique des deux vantaux à la position fermée.The present invention relates to hinged doors with two leaves, of the type in particular of those which equip cubicles for public telephones, and it is more particularly intended to allow the realization of a security mechanism which is arranged in the first place to ensure the simultaneous angular displacement of the two leaves when only one of them is operated by the user, secondly to allow one of these leaves to be operated while the other remains momentarily immobile as a result of a stop effect which is temporarily exerted on it, this immobilized leaf automatically pivoting in the same direction as the first as soon as the aforementioned effect ceases, and thirdly for operating the automatic return of the two leaves to the closed position.
Si l'on considère le cas susmentionné des cabines téléphoniques, on conçoit sans peine qu'il est nécessaire de relier l'un à l'autre les deux vantaux de leur porte battante de façon à ce que celle-ci s'ouvre entièrement même dans le cas où, par inadvertance ou par le fait qu'il ne dispose que d'une seule main libre, un utilisateur vient à ne manoeuvrer qu'un seul desdits vantaux. Par ailleurs, il faut que le vantail qui est manoeuvré par l'utilisateur puisse pivoter sans dommage dans le cas où le vantail opposé serait immobilisé angulairement par la présence d'un autre utilisateur qui attend à l'extérieur de la cabine ou qui se trouve déjà à l'intérieur de celle-ci, ce vantail devant néanmoins pivoter à son tour dès que le blocage momentané a cessé.If we consider the aforementioned case of telephone booths, it is easy to see that it is necessary to connect the two leaves of their hinged door to each other so that it opens fully even in the event that, inadvertently or by the fact that he has only one free hand, a user comes to operate only one of said leaves. Furthermore, it is necessary that the leaf which is operated by the user can pivot without damage in the event that the opposite leaf is immobilized angularly by the presence of another user who is waiting outside the cabin or who is located already inside of it, this leaf must nevertheless pivot in turn as soon as the momentary blocking has ceased.
Dans le document FR-A-2 568 929 (MECELEC), on a décrit un mécanisme du type envisagé, permettant de remplir la fonction qui a été ci-dessus exposée. Ce mécanisme fait appel à deux dispositifs compensateurs qui sont attelés par l'une de leurs extrémités à l'un, respectivement à l'autre, des deux vantaux et dont la longueur peut se modifier automatiquement à l'encontre de moyens élastiques de rappel sous l'effet d'un effort axial exercé suivant une direction donnée tout en restant invariable en cas d'effort axial exercé suivant la direction opposée, ces deux dispositifs étant par ailleurs attelés à un même palonnier propre à inverser la direction des efforts qui s'exercent axialement sur eux.In document FR-A-2 568 929 (MECELEC), a mechanism of the type envisaged has been described, making it possible to fulfill the function which has been described above. This mechanism uses two compensating devices which are coupled by one of their ends to one, respectively to the other, of the two leaves and the length of which can be modified automatically against elastic return means under the effect of an axial force exerted in a given direction while remaining invariable in the event of an axial force exerted in the opposite direction, these two devices being moreover coupled to the same lifting beam capable of reversing the direction of the forces which axially exert on them.
Dans la forme de réalisation exposée dans le document sus-indiqué, chaque dispositif compensateur était formé par un cylindre à l'intérieur duquel coulisse télescopiquement une tige pourvue en bout d'une tête constituant butée pour un ressort prenant par ailleurs appui contre le fond dudit cylindre qui est traversé par la tige.In the embodiment described in the above-mentioned document, each compensating device was formed by a cylinder inside which telescopically slides a rod provided at the end of a head constituent stop for a spring also bearing against the bottom of said cylinder which is crossed by the rod.
Un tel système permet bien d'obtenir le résultat recherché, mais il convient d'observer que sa construction est relativement coûteuse et qu'au surplus il se prête très mal à une adaptation aux différentes largeurs des vantaux susceptibles d'être rencontrés en pratique, en ce sens qu'un mécanisme donné ne peut convenir qu'à un seul entraxe des pivots des vantaux.Such a system does indeed allow the desired result to be obtained, but it should be observed that its construction is relatively expensive and that, moreover, it lends itself very poorly to adaptation to the different widths of the leaves likely to be encountered in practice, in the sense that a given mechanism can only be suitable for a single center distance of the leaf pivots.
C'est à ces inconvénients que la présente invention entend remédier, et ce à l'aide du dispositif de sécurité qui est défini à la revendication 1 et aux revendications subséquentes qui lui sont rattachées. Suivant l'invention, on lie angulairement chacun des vantaux de la porte à un organe d'enroulement présentant deux tambours superposés à diamètres différents, et l'on réunit le tambour à petit diamètre de l'un au tambour à grand diamètre de l'autre, et vice versa, par deux éléments funiculaires qui s'enroulent sur leurs tambours dans des directions opposées et sur la longueur de chacun desquels sont interposés des moyens élastiquement déformables à la traction et à la compression, avantageusement constitués par de simples ressorts hélicoïdaux à spires non jointives.It is these drawbacks that the present invention intends to remedy, and this using the safety device which is defined in claim 1 and the subsequent claims which are attached to it. According to the invention, each of the door leaves is angularly linked to a winding member having two superimposed drums with different diameters, and the small diameter drum of one is joined to the large diameter drum of the other, and vice versa, by two funicular elements which are wound on their drums in opposite directions and along the length of each of which are interposed elastically deformable means in tension and compression, advantageously constituted by simple helical springs with non-contiguous turns.
On comprend que lorsque les deux vantaux sont simultanément manoeuvrés à l'ouverture, l'enroulement différentiel dans des directions opposées d'envidage des deux extrémités de chaque élément funiculaire provoque l'étirement des ressorts qui assurent ensuite le rappel élastique des portes à la position de fermeture, ce mouvement de rappel étant préférablement régulé par un amortisseur classique associé à l'un au moins des organes d'enroulement.It is understood that when the two leaves are simultaneously operated at the opening, the differential winding in opposite directions of winding of the two ends of each funicular element causes the stretching of the springs which then ensure the elastic return of the doors to the position closing, this return movement being preferably regulated by a conventional damper associated with at least one of the winding members.
Dans le cas où l'un seulement des deux vantaux est manoeuvré à l'ouverture par l'utilisateur, le vantail opposé est contraint de suivre le mouvement par suite de la liaison existant entre les deux organes d'enroulement, les deux ressorts assurant le rappel à la position de fermeture.In the case where only one of the two leaves is operated upon opening by the user, the opposite leaf is forced to follow the movement as a result of the connection existing between the two winding members, the two springs ensuring the recall to the closed position.
Dans l'hypothèse enfin où l'un des vantaux est manoeuvré à l'ouverture alors que l'autre est momentanément immobilisé angulairement, l'étirement de l'un des éléments funiculaires joint à la contraction simultanée de l'autre permet le pivotement du vantail qui est manoeuvré, et ce en dépit de l'immobilité de l'autre vantail, ce dernier étant amené en position ouverte dès qu'il a recouvré sa liberté de pivotement.In the event that one of the leaves is operated at the opening while the other is momentarily immobilized angularly, the stretching of one of the funicular elements joined to the simultaneous contraction of the other allows the pivoting of the leaf which is maneuvered, and this despite the immobility of the other leaf, the latter being brought into the open position as soon as it has recovered its freedom of pivoting.
Il doit être observé qu'un tel mécanisme est susceptible d'être immédiatement adapté à des portes différentes moyennant allongement ou au contraire raccourcissement des éléments funiculaires, dont chacun desquels est susceptible d'être très simplement constitué par deux portions de câble reliées par un ressort hélicoïdal.It should be observed that such a mechanism is capable of being immediately adapted to different doors by lengthening or on the contrary shortening the funicular elements, each of which is capable of being very simply constituted by two portions of cable connected by a spring. helical.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
Fig. 1 est une vue en perspective représentant la partie supérieure d'une porte battante à deux vantaux équipée d'un mécanisme de sécurité suivant l'invention.Fig. 1 is a perspective view showing the upper part of a swing door with two leaves fitted with a safety mechanism according to the invention.
Fig. 2 et 3 sont des vues analogues illustrant le fonctionnement de ce mécanisme.Fig. 2 and 3 are similar views illustrating the operation of this mechanism.
Sur ce dessin, les références 1 et 2 désignent les deux vantaux de la porte battante d'une cabine publique de téléphone. A son sommet, le bord extérieur de chaque vantail 1 ou 2 est muni d'une penture 3 (fig. 1) fixée radialement en bout d'un arbre vertical ou pivot 4, lequel est convenablement supporté par la carcasse fixe de la cabine de façon à pouvoir librement tourner sur lui-même. Il va de soi que le bord inférieur (non représenté) de chacun des vantaux 1 et 2 est supporté par un pivot classique, orienté suivant l'axe du pivot 4 correspondant.In this drawing,
Sur chacun des pivots 4 est calé un organe d'enroulement référencé 5 pour le vantail 1, 6 pour le vantail 2. Chaque organe 5 ou 6 est agencé pour présenter deux parties ou tambours superposés 5a et 5b, respectivement 6a et 6b, établis à deux diamètres différents. On observera que la disposition verticale de ces tambours est inversée sur les deux organes 5 et 6, en ce sens que le tambour 5a à petit diamètre est disposé au-dessus du tambour 5b de l'organe 5, alors que le petit tambour 6a est situé, au-dessus du tambour 6b du même organe 6.On each of the
Les deux organes 5 et 6 sont liés angulairement l'un à l'autre par deux éléments funiculaires superposés 7 et 8 dont chacun, orienté à l'horizontale, est constitué par deux portions de câble métallique réunies l'une à l'autre par un ressort hélicoïdal 7a, respectivement 8a. L'extrémité libre de chaque portion de câble est arrimée sur la périphérie de l'un des tambours de chaque organe 5 et 6, de sorte que l'élément 7 relie le grand tambour 5b au petit tambour 6a, tandis que dans un plan horizontal situé à un niveau inférieur, l'élément 8 réunit le petit tambour 5a au grand tambour 6b.The two
Il convient d'observer que les deux portions de câble de chaque élément funiculaire 7 et 8 sont attachées à leurs tambours de façon à ce que lors de la rotation en sens opposés des pivots 4 et des organes 5 et 6, l'une desdites portions s'enroule tandis que l'autre se déroule.It should be observed that the two portions of cable of each
Sur chaque élément 7 et 8 est prévu un tendeur classique 7b, 8b qui permet de régler la tension des ressorts 7a et 8a ; ce réglage est opéré de manière à ce qu'à la position de fermeture illustrée en fig. 1, les spires des deux ressorts ne soient pas jointives. Par ailleurs, à l'un au moins des organes 5 et 6 (au seul organe 6 dans l'exemple de réalisation envisagé), est avantageusement associé un amortisseur 9 de type usuel, propre à freiner le pivotement angulaire de l'organe auquel il est attelé ; cet attelage est réalisé à l'aide d'un maneton radial 5c, 6c qui est interposé entre les deux tambours de l'organe envisagé et dont l'extrémité libre est liée à la tige mobile 9a de l'amortisseur 9.On each
On notera que chaque maneton 5c, 6c est agencé pour coopérer avec une butée fixe 10 solidaire de la carcasse de la cabine, afin de limiter l'amplitude du pivotement des vantaux dans le sens de l'ouverture.It will be noted that each
On comprend qu'à la position fermée illustrée en fig. 1, la légère tension exercée par les ressorts 7a et 8a sur les éléments 7 et 8 sollicite en rotation les organes 5 et 6 dans des sens opposés, si bien que les deux vantaux 1 et 2 sont ainsi maintenus en appui contre une butée fixe 11 prévue au centre de la porte.It is understood that in the closed position illustrated in FIG. 1, the slight tension exerted by the
Si l'on suppose qu'à partir de cette position de fermeture, un utilisateur, désirant pénétrer dans la cabine, agit simultanément sur les deux vantaux 1 et 2, le déplacement angulaire des pivots 4 et des organes 5 et 6 provoque, au niveau de chaque élément funiculaire 7 et 8, l'enroulement d'une portion de câble et le déroulement de la portion opposée. Par suite de la différence de diamètre des deux tambours auxquels sont arrimées les portions de câble d'un même élément, cette opération d'envidage-dévidage détermine le déplacement longitudinal de chaque élément 7 et 8, ainsi que l'étirement du ressort 7a, 8a (voir fig. 2), et ce jusqu'à ce que les manetons 5c, 6c viennent en appui contre les butées fixes 10.If we assume that from this closed position, a user, wishing to enter the cabin, acts simultaneously on the two
Du fait de cet étirement, les deux resorts précités assurent le rappel élastique des deux vantaux 1 et 2 dès qu'ayant pénétré dans la cabine, l'utilisateur cesse son action sur lesdits vantaux, étant noté que l'amortisseur 9 intervient alors pour freiner le mouvement de fermeture.Due to this stretching, the two aforementioned resorts ensure the elastic return of the two
Il faut ici observer que le même processus se produit dans le cas où pour ouvrir la porte battante, l'utilisateur ne se sert que d'une seule main et n'agit que sur l'un des deux vantaux, que ce soit le gauche ou le droit : les éléments funiculaires 7 et 8 assurent la liaison permanente entre les deux vantaux 1 et 2, de sorte que lesdits vantaux sont simultanément amenés en position ouverte et reviennent d'eux-mêmes à la position de fermeture dès que l'action de l'utilisateur cesse.It should be noted here that the same process occurs in the case where to open the hinged door, the user uses only one hand and acts only on one of the two leaves, either the left or the right: the
Si maintenant l'on suppose que l'utilisateur manoeuvre à l'ouverture un seul vantail (le vantail 1 en fig. 3) alors que l'autre vantail ne peut pivoter par suite d'un obstacle imprévu (schématisé en fig. 3 sous la forme d'une butée fixe 12 placée immédiatement en avant du vantail 2 en position fermée), le déplacement angulaire de l'organe 5 va engendrer simultanément :
- un effet de traction au niveau de l'élément funiculaire 7 dont le
ressort 7a va s'étirer du fait de l'enroulement de la portion de câble amarrée sur legrand tambour 5b, si bien que le vantail 1 pourra être amené à la position d'ouverture ; - un effet de compression au niveau de l'élément funiculaire 8 dont le
ressort 8a va se contracter axialement pour permettre auvantail 2 de rester immobile ; - étant observé que ce
vantail 2 sera automatiquement amené en position d'ouverture par leressort 7a dès que labutée 12 aura été effacée, et que les deux vantaux 1 et 2 reviendront simultanément à la position de fermeture dès que l'utilisateur aura cessé son action sur le vantail 1.
- a traction effect at the level of the funicular element 7 whose
spring 7 a will stretch due to the winding of the portion of cable moored on thelarge drum 5 b , so that the leaf 1 may be brought to the open position; - a compression effect at the level of the
funicular element 8, thespring 8 a of which will contract axially to allow theleaf 2 to remain stationary; - it being observed that this
leaf 2 will be automatically brought into the open position by thespring 7 a as soon as thestop 12 has been cleared, and that the two leaves 1 and 2 will return simultaneously to the closed position as soon as the user has stopped its action on the leaf 1.
Le dispositif de sécurité suivant l'invention permet donc bien d'obtenir le fonctionnement recherché. Sa construction est peu coûteuse et sa structure lui permet d'être imédiatement adapté à l'entraxe des deux pivots 4 de la porte battante, puisqu'il suffit à cet effet de modifier la longueur des câbles des éléments funiculaires 7 et 8, toutes les autres pièces restant identiques.The safety device according to the invention therefore makes it possible to obtain the desired operation. Its construction is inexpensive and its structure allows it to be immediately adapted to the distance between the two
Bien mieux, ces pièces sont susceptibles d'être indifféremment utilisées pour des portes battantes à ouverture vers l'intérieur ou vers l'extérieur, et même pour des portes équipées de deux vantaux à pivotement en directions opposées (un vantail à ouverture vers l'intérieur et un vantail à ouverture vers l'extérieur).Even better, these parts can be used interchangeably for swing doors opening inwards or outwards, and even for doors fitted with two leaves pivoting in opposite directions (one leaf opening towards the interior and a leaf opening towards the exterior).
A la limite, pour l'équipement d'une porte à un seul vantail, on peut encore avoir recours à un seul organe d'enroulement associé à un seul élément funiculaire dont l'extrémité libre est alors attachée en un point fixe.Ultimately, for equipping a door with a single leaf, it is also possible to have recourse to a single winding member associated with a single funicular element, the free end of which is then attached at a fixed point.
On conçoit en particulier que le dispositif de sécurité suivant l'invention est susceptible d'être appliqué à des portes battantes autres que celles qui équipent les cabines téléphoniques.It is understood in particular that the security device according to the invention is capable of being applied to swing doors other than those which equip telephone boxes.
