Description

Invention concerne un vérin applicable à l'ouvertu- re et à la fermeture notamment des exutoires de fumé.  Invention relates to a jack applicable to opening and closing including smoke outlets.

l'objet de l'invention se rattache au secteur technique des moyens de commande d'ouverture et de fermeture de chassis mobiles. the object of the invention is related to the technical sector of the movable frame opening and closing control means.

I1 est connu d'utiliser dans les bâtiments, des exutoires de fumée, coupoles lanterneaux ou autres composés essen tiellenent d'une costière support et d'au moins un dome d'éclairement. En plus de leur fonction d'éclairement ces coupoles permettent l'aération des bâtiments, notamment le désen+umage.  It is known to use in buildings smoke outlets, skylight domes or other essen tial material of a support curb and at least one dome of illumination. In addition to their lighting function these cupolas allow aeration of buildings, including désen + umage.

Pour celaq la costière est équipée d'un cadre ouvrant monté sur paumelles ou autres et équipée de moyens autorisant leur ouverture et leur maintien en position ouverte
Par exemple, la costière et le cadre ouvrant peuvent recevoir en combinaison, des vérins télescopiques assurant une ouverture instantanée et automatique après déverrouillage de l'ensemble. Généralement, pour des raisons de sécurité, l'ouver- ture s'effectue au-dela de 900, selon un angle de l'ordre de 1100. Ces vérins et/ou partie de l'ensemble de la coupole, sont en outre assujettis à différents organes pour être commandés à distance en vue de l'ouverture et de la fermeture tels que par exemple au moyen d'une commande par cible souple et bottier de manoeuvre commandé à partir du sol.For this the curb is equipped with an opening frame mounted on hinges or other and equipped with means allowing their opening and holding in the open position
For example, the curb and the opening frame can receive in combination, telescopic cylinders providing instant and automatic opening after unlocking the assembly. Generally, for reasons of safety, the opening is carried out beyond 900, according to an angle of the order of 1100. These jacks and / or part of the whole of the dome are also subject to to different organs to be remotely controlled for opening and closing such as for example by means of a flexible target control and maneuvering box commanded from the ground.

Si les différants moyens employés donnent à peu près satisfaction pour l'ouverture, il n'en est pas de même pour la fermeture En effet, la coupole étant maintenue ouverte au delà de sa position verticale d'équilibre à 9Q, il est nécessaire de vaincre, d'une part, la résistance des vérins et d'autre part le poids de la coupole. If the different means employed give approximately satisfaction for the opening, it is not the same for the closure. Indeed, since the dome is kept open beyond its equilibrium vertical position at 9Q, it is necessary to overcome, on the one hand, the resistance of the cylinders and on the other hand the weight of the dome.

Le problème étant ainsi posé, invention s'est fixée pour but, d'une manière simple et rationnelle, de remédier à ces inconvénients en créant une nouvelle conception de vérin permettant de diminuer, d'une manière importante, la résistance à la fermeture des vérins. The problem being thus posed, the object of the invention is to provide a simple and rational way of overcoming these drawbacks by creating a new cylinder design which makes it possible to reduce, in a significant manner, the closing resistance of the cylinders.

Dans ce but, le vérin est remarquable en ce qu'il comprend, en combinaison, deux chambres intérieures séparées d'une manière étanche, dans chacune des chambres étant montée, en opposition et à libre coulissement, une tige de piston. Dans l'une des chambres le piston est soumis à une force de poussée sous l'effet d'un fluide comprimé au repos qui tend à faire sortir la tige, tandis que dans l'autre chambre, le piston est soumis à une force opposée d'intensité déterminée, qui tend à maintenir rentrée la tige, l'une des tiges étant reliée à une partie fixe de la coupole, l'autre tige étant reliée à la partie ouvrante. For this purpose, the jack is remarkable in that it comprises, in combination, two inner chambers separated in a sealed manner, in each of the chambers being mounted, in opposition and with free sliding, a piston rod. In one of the chambers the piston is subjected to a thrust force under the effect of a compressed fluid at rest which tends to pull out the rod, while in the other chamber, the piston is subjected to an opposite force. determined intensity, which tends to keep the rod returned, one of the rods being connected to a fixed part of the dome, the other rod being connected to the opening part.

L'invention est exposée ci-aprbs plus en détail,- à l'aide des dessins qui représentent seulement une forme d'exécution. The invention is explained below in more detail, with the aid of the drawings which represent only one embodiment.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant dune manière non limitative en se réfé- rant aux exemples de réalisation des figures des dessins. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner with reference to the exemplary embodiments of the figures of the drawings.

Selon l'invention, le fut du vérin (1) présente deux chambres intérieures (la) et (lb) séparées d'une manière étanche au moyen par exemple d'une bague (2) en tout matériau approprié. According to the invention, the cylinder (1) has two inner chambers (1a) and (1b) separated in a sealed manner by means for example of a ring (2) of any suitable material.

Dans la chambre (la) est montée à frottement et à libre coulissement, un piston (3) relié à une tige (3a) guidée d'une manière parfaitement étanche, dans un fourreau coaxial (4) positionné en bout du fat (1).  In the chamber (la) is mounted to friction and free sliding, a piston (3) connected to a rod (3a) guided in a perfectly sealed manner, in a coaxial sleeve (4) positioned at the end of the fat (1) .

l'arrière du piston (3), la chambre (lal) est remplie d'un fluide comprimé au repos qui exerce une force de pous sée F à l'encontre dudit piston, ce qui tend à faire constamment sortir la tige (3a). the rear of the piston (3), the chamber (lal) is filled with a compressed fluid at rest which exerts a pushing force F against said piston, which tends to constantly pull out the rod (3a) .

De l'autre coté du piston (r-'.), la chambre (la2) re çoit un petit volume d'huile ou autre fluide hydraulique, pour assurer l'amortissement de l'ensemble du piston (3) et de la tige (3a) en fin de course dudit piston. On the other side of the piston (r- '), the chamber (la2) receives a small volume of oil or other hydraulic fluid, to ensure the damping of the entire piston (3) and the rod (3a) at the end of stroke of said piston.

A cet effet, d'une manière connue, une rondelle (5) est montée sur la tige (3a) en appui facial contre le piston (3) pour obturer partiellement un trou laminaire (3b) formé dans l'épaisseur dudit piston, parallèlement à ses génératrices. En correspondance avec ce trou (b), la rondelle (5) présente un orifice ou encoche pour autoriser le passage du fluide hydraulique au fur et à mesure du déplacement de la tige. Cette rondelle d'appui (5) est assujettie a un ressort de rappel (6) monté sur la tige (3a > afin de pouvoir être excamotée temporairement pour mieux. dégager le trou (3b) afin d'accélérer l'écoulement du fluide hydraulique lors de l'enfoncement de la tige (3a). For this purpose, in a known manner, a washer (5) is mounted on the stem (3a) in the form of a bearing against the piston (3) to partially seal a laminar hole (3b) formed in the thickness of said piston, in parallel to its generators. In correspondence with this hole (b), the washer (5) has a hole or notch to allow the passage of hydraulic fluid as the movement of the rod. This bearing washer (5) is attached to a return spring (6) mounted on the rod (3a) so that it can be temporarily exchanged to better disengage the hole (3b) in order to accelerate the flow of the hydraulic fluid. during the depression of the rod (3a).

L'extrémité (3al) de la tige (3a) est et agencée pour etre accouplée, à libre articulation sur une partie fixe ou ouvrante de l'ensemble de la coupole. The end (3al) of the rod (3a) is and arranged to be coupled, free articulation on a fixed or opening part of the entire dome.

La chambre interne (lb) reçoit, d'une manière opposée et coaxiale à la chambre (1a), un piston (7) relié à sa tige (7a). Comme indiqué précédemment, la tige (7a) est montée à coulissement guidé et étanche dans un fourreau (8) disposé à lSau- tre extrémité du fut du vérin (1). De meme, la tige (7a) reçoit une rondelle d'appui (9) rappelée par ressort (10) et coopérant avec le piston (7) pour entre en communication avec un trou laminaire (7b) que présente ledit piston. The inner chamber (1b) receives, in an opposite manner and coaxial with the chamber (1a), a piston (7) connected to its rod (7a). As indicated above, the rod (7a) is mounted to slide guided and sealed in a sleeve (8) disposed at the other end of the cylinder (1). Similarly, the rod (7a) receives a bearing washer (9) spring biased (10) and cooperating with the piston (7) to communicate with a laminar hole (7b) that has said piston.

Selon l'invention, la chambre (1b1), entre le piston et l'extrémité correspondante du fut du vérin, est remplie d'un fluide qui est d'une manière préférée quoique non rigoureusement limitative, un fluide hydraulique. En amont du piston i7), la chambre (lb) n'est Fas mise en pression afin de conserver une poussée contrôlée mais lente, cette partie de chambre (lb2) peut éventuellement titre mise en pression mais la force d'intensité de poussée F1 exercée sur ledit piston (7) est très inférieure a la force de poussée F exercée sur le piston ().  According to the invention, the chamber (1b1) between the piston and the corresponding end of the cylinder is filled with a fluid which is preferably but not strictly limited, a hydraulic fluid. Upstream of the piston i7), the chamber (1b) is Fas pressurized in order to maintain a controlled but slow thrust, this chamber portion (lb2) may possibly be pressurized but the thrust force force F1 exerted on said piston (7) is much less than the thrust force F exerted on the piston ().

L'extrémité (7al) de la tige (7a) est agencée pour être accouplée, a libre articulation, sur une partie fixe ou ouvrante de l'ensemble de la coupole. À cet effet il convient d'analyser le fonctionnement du vérin en se référant plus particulièrement aux figures 2 à 4 du dessin. The end (7al) of the rod (7a) is arranged to be coupled, free articulation, on a fixed or opening part of the entire dome. For this purpose it is necessary to analyze the operation of the cylinder with particular reference to Figures 2 to 4 of the drawing.

Un couple de vérin selon J'invention, est monté en combinaison avec le cadre ouvrant (C1) de la coupole (C) et une partie fixe (C2) telle que la costière. Par exemple la tige (3a) est fixée à libre articulation sur une partie de la costié re, tandis que la tige (7a) est fixée sur une partie du cadre ouvrant. Un montage inverse peut étire prévu. La coupole (C) est asservie, dans l'exemple illustré, à une commande par câble souple et boîtie- de commande au sol. A pair of jack according to the invention is mounted in combination with the opening frame (C1) of the dome (C) and a fixed part (C2) such as the curb. For example the rod (3a) is fixed to free articulation on a portion of the costié re, while the rod (7a) is fixed on a portion of the opening frame. Reverse mounting can be planned. The dome (C) is slaved, in the example shown, to a flexible cable control and ground control box.

Après déverrouillage automatique ou manuel du système de fermeture de la coupole, la tige (3a) est déployée automatiquement sous l'effet de poussée (F) résultant du fluide comprimé dans la chambre < la) assurant concomitamment l'ouverture de la coupole jusqu'à sa position verticale d'équilibre à 90 (figure 3).  After automatic or manual unlocking of the closure system of the cupola, the rod (3a) is automatically deployed under the effect of thrust (F) resulting from the compressed fluid in the chamber <la) ensuring concomitantly the opening of the cupola up to at its equilibrium vertical position at 90 (Figure 3).

Pratiquement en fin de course du déplacement de la tige (3a), compte-tenu de sa vitesse de déplacement résultant de la force de pression F exercée l'huile contenue dans la chambre (1a2) est chassée derrière le piston (3) dans la chambre (lal) en passant par le trou de la rondelle (5) et le canal interne du piston ce qui permet d'avoir un amortissement en fin de course. Practically at the end of the stroke of displacement of the rod (3a), given its speed of displacement resulting from the pressure force F exerted, the oil contained in the chamber (1a2) is driven behind the piston (3) in the chamber (lal) through the hole of the washer (5) and the internal channel of the piston which allows a damping at the end of the race.

Au delà de cette position d'équilibre, la coupole (C) par gravi té, continue à basculer en arrière, ce qui a pour effet de tirer la tige (7a) d'une manière lente et progressiveq l hul- le contenue dans la chambre (la2) s'échappant par le trou cadre bré de la rondelle (9) et à travers le piston (7 > jusqu'à la position d'ouverture maximum admise par la coupole de l'ordre de 110 (figure 4) et au delà selon des applications spécifiques. Beyond this position of equilibrium, the dome (C) by gravity continues to tilt backward, which has the effect of pulling the rod (7a) in a slow and progressive way the hul- le contained in the chamber (la2) escaping through the broken frame hole of the washer (9) and through the piston (7> to the maximum open position allowed by the dome of the order of 110 (Figure 4) and beyond according to specific applications.

Pour la fermeture de la coupole, on agit, dune ma nière connue sur la commande du câble, ce qui engendre sur la tige (7a) une force (F2) de sorte que le fluide hydraulique, précédemment passé dans la chambre (lbl) exerce sur le piston (7) une pression suffisante pour décoller la rondelle (?) et peut, de ce fat, passer librement au travers dudit piston jus qu'à la position rentrée de la tige correspondant à la position d'ouverture verticale de la coupole. n noter que l'ensemble du piston (7) et de sa tige est ramené en position initiale avec un effort minimum compte-tenu de la faible valeur de la pression choisie en amont du piston (7) en position de repos. In order to close the cupola, it acts, in a known manner, on the cable control, which generates on the rod (7a) a force (F2) so that the hydraulic fluid previously passed in the chamber (lbl) exerts on the piston (7) a sufficient pressure to take off the washer (?) and may, from this fat, freely pass through said piston until the retracted position of the rod corresponding to the vertical opening position of the dome . Note that the entire piston (7) and its rod is returned to the initial position with a minimum effort given the low value of the pressure selected upstream of the piston (7) in the rest position.

La position d'équilibre de la coupole étant franchie, c'est la tige (3a) du piston (3) qui est sollicitée, l'huile passant librement à travers ledit piston (3) jusqu'à la fermeture complète de la coupole La force de pression que doit vaincre le piston (), compte-tenu de la mise en pression initiale de la chambre (la), est supérieure à celle que doit vaincre le piston (7), de sorte que la fermeture de la coupole, au dela de sa position d'équilibre, est fortement amortie. The equilibrium position of the dome being crossed, it is the rod (3a) of the piston (3) which is stressed, the oil passing freely through said piston (3) until the complete closure of the dome La the pressure force that must overcome the piston (), given the initial pressurization of the chamber (la), is greater than that which must overcome the piston (7), so that the closure of the dome, at Beyond its equilibrium position, it is strongly damped.

I1 est bien évident, sans pour cela sortir du cadre de l'invention, que chacune des chambres du vérin peut recevoir tout fluide d'amortissement.  It is obvious, without departing from the scope of the invention, that each of the cylinder chambers can receive any damping fluid.
