This resilient member is such that its stiffness increases suddenly when passing from the shut off position of the valve to its opening position.

Description

Briquet à gaz. Gas lighter.
La présente invention concerne un briquet à gaz liquéfié et, plus particulièrement, une valve d'obturation du courant gazeux délivré par ce briquet. On connaît des briquets dans lesquels la valve d'obturation se compose d'un clapet, parfois constitué par le brûleur du briquet, pourvu d'un joint d'obturation, et d'un siège de clapet, à la base duquel est située l'arrivée du gaz, Des moyens sont prévus pour commander le déplacement du clapet et comprennent, par exemple, un organe de commande, lié à ce clapet, et un élément élastique, constitué la plupart du temps par un ressort, qui sollicite l'organe de commande et, par son intermédiaire, le clapet.The present invention relates to a liquefied gas lighter and, more particularly, a valve for shutting off the gas stream delivered by this lighter. Lighters are known in which the shutter valve consists of a valve, sometimes constituted by the lighter's burner, provided with a shutter seal, and a valve seat, at the base of which is located l arrival of the gas, means are provided for controlling the movement of the valve and comprise, for example, a control member, linked to this valve, and an elastic element, constituted most of the time by a spring, which biases the member and, through it, the valve.
La fonction de cet élément élastique est double: D'une part, il assure l'obturation de la valve, en maintenant le clapet appliqué sur son siège avec une force constante, prédéterminée. Dans la plupart des briquets, toutefois, les pièces constituant la valve peuvent présenter des variations dimensionnelles, soit du fait des tolérances de fabrication, soit par suite de variations des conditions extérieures (température, hygrométrie, etc...). Ces variations dimensionnelles ont pour effet de modifier l'aptitude à la déformation de l'élément élastique et,par conséquent, sa force d'obturation et, pour minimiser ces variations, il est donc souhaitable que la raideur de l'élément élastique soit faible.The function of this elastic element is twofold: On the one hand, it closes the valve, keeping the valve applied to its seat with a constant, predetermined force. In most lighters, however, the parts constituting the valve may exhibit dimensional variations, either due to manufacturing tolerances, or as a result of variations in external conditions (temperature, humidity, etc.). These dimensional variations have the effect of modifying the deformation ability of the elastic element and, consequently, its sealing force and, to minimize these variations, it is therefore desirable that the stiffness of the elastic element is low. .
D'autre part, l'élément élastique agit comme un organe de rappel ramenant le clapet de sa position ouverte à sa position d'obturation, lorsque l'organe de commande n'est plus sollicité par l'utilisateur. Dans ce but, il doit vaincre les forces de frottement s'opposant au déplacement du clapet, ce qui implique une force de rappel importante. Pour une déformation donnée du ressort, cette force de rappel est donc d'autant plus importante que la raideur du ressort est élevée. Ces deux fonctions de l'élément élastique font donc appel à des raideurs de ressort opposées. Aussi, les dis positifs de commande de valve de briquets à gaz d'un type connu ne satisfont généralement qu'à l'une ou à l'au tre de ces conditions. Autrement dit: ou bien leur raideur est suffisamment faible .pour que les variations dimensionnelles des éléments constituant le dispositif n'aient que peu d'influence sur la force d'obturation et, dans ce cas, leur raideur est insuffisante pour as surer un rappel correct du dispositif en position d'obturation; ou bien leur raideur est suffisante pour effectuer correctement le rappel du clapet, mais, alors, les variations dimensionnelles des éléments influeront notablement sur la force d'obturation. On a déjà proposé des éléments élastiques pour valve d'obturation de briquets, dont la raideur augmente de façon continue au cours du déplacement de la valve, depuis sa position d'obturation jusqu'à sa position d'ouverture. Cependant, si un élément à variation de raideur continue peut présenter, en position d'obturation, une raideur suffisamment faible et, en position d'ouverture, une force de rappel suffisamment élevée, il comporte l'inconvénient de posséder, au voisinage de la zone d'obturation, une raideur plus élevée qu'un ressort de raideur constante, ayant la même raideur en position d'obturation. Il en résulte que les variations dimensionnelles éventuelles des éléments constitutifs de la valve d'obturation auront une influence plus grande sur la force d'obturation du clapet.On the other hand, the elastic element acts as a return member bringing the valve from its open position to its closed position, when the control member is no longer requested by the user. For this purpose, it must overcome the friction forces opposing the movement of the valve, which implies a significant restoring force. For a given deformation of the spring, this restoring force is therefore all the greater the higher the stiffness of the spring. These two functions of the elastic element therefore call for opposite spring stiffnesses. Also, the devices for controlling the valve of gas lighters of a known type generally satisfy only one or the other of these conditions. In other words: either their stiffness is sufficiently low. So that the dimensional variations of the elements constituting the device have little influence on the shutter force and, in this case, their stiffness is insufficient to ensure a recall. correct device in the closed position; or else their stiffness is sufficient to correctly return the valve, but, then, the dimensional variations of the elements will have a significant influence on the shutter force. Elastic elements have already been proposed for shutter valve for lighters, the stiffness of which increases continuously during the displacement of the valve, from its shutter position to its open position. However, if an element with continuous stiffness variation can have, in the closed position, a sufficiently low stiffness and, in the open position, a sufficiently high restoring force, it has the disadvantage of having, in the vicinity of the shutter zone, a higher stiffness than a spring of constant stiffness, having the same stiffness in the closed position. As a result, the possible dimensional variations of the constituent elements of the shutter valve will have a greater influence on the shutter force of the valve.
La présente invention vise à combiner les avantages des ressorts à raideur constante et des éléments élastiques à variation' continue de raideur, en éliminant les inconvénients propres à chacun de ces deux types d'organe.The present invention aims to combine the advantages of springs with constant stiffness and elastic elements with continuous variation in stiffness, by eliminating the drawbacks specific to each of these two types of member.
A cet effet, l'invention a pour objet un briquet à gaz liquéfié comprenant une arrivée de gaz sur laquelle est .disposée une valve munie d'un élément élastique, qui la maintient en position fermée et assure son rappel de la position ouverte à la position fermée, ce briquet étant caractérisé en ce que ledit élément élastique possède une raideur qui passe d'une façon discontinue d'une première valeur constante donnée à une seconde valeur constante donnée, supérieure à la première, lorsque la valve passe de la position d'obturation à la position d' ouverture.To this end, the invention relates to a liquefied gas lighter comprising a gas inlet on which is arranged a valve provided with an elastic element, which maintains it in the closed position and ensures its recall from the open position to the closed position, this lighter being characterized in that said elastic element has a stiffness which passes discontinuously from a first given constant value to a second constant value given, greater than the first, when the valve passes from the closed position to the open position.
Au voisinage de la position d'obturation, la raideur de l'élément élastique est ainsi égale à la raideur minimale choisie pour l'obturation et les variations dimensionnelles éventuelles des éléments constituant la valve ont une influence minimale sur la force d'obturation. En position d'.ouverture, par contre, l'élément élastique aura, comme un ressort à variation de raideur continue, une raideur suffisante, lui conférant une force de rappel suffisamment élevée.In the vicinity of the shutter position, the stiffness of the elastic element is thus equal to the minimum stiffness chosen for the shutter and the possible dimensional variations of the elements constituting the valve have a minimal influence on the shutter force. In the open position, on the other hand, the elastic element will, like a spring with variation of continuous stiffness, have sufficient stiffness, giving it a sufficiently high restoring force.
Suivant l'invention, l'élément élastique pourra être constitué d'un ressort dont on fera varier la longueur utile en cours d'utilisation, par exemple en l'équipant d'une butée, qui, au cours de la compression, viendra en contact avec une butée fixe solidaire du corps du briquet. On pourra également disposer une butée sur l'organe de commande, qui, au cours de son actionnement, viendra en contact avec le ressort.According to the invention, the elastic element may consist of a spring, the useful length of which will be varied during use, for example by equipping it with a stop, which, during compression, will come in contact with a fixed stop secured to the body of the lighter. It will also be possible to have a stop on the control member, which, during its actuation, will come into contact with the spring.
Les dessins annexés illustrent ces diverses formes de réalisation de l'invention. Sur ces dessins:The accompanying drawings illustrate these various embodiments of the invention. In these drawings:
La figure 1 est une coupe transversale partielle d'un briquet selon l'invention, suivant la ligne I-I de la figure 2;Figure 1 is a partial cross section of a lighter according to the invention, along the line I-I of Figure 2;
La figure 2 est une vue de dessus correspondant à la figure 1 , la molette d' allumage étant ôtée ;Figure 2 is a top view corresponding to Figure 1, the ignition wheel being removed;
La figure 3 est une vue en perspective éclatée de la pédale de commande et du ressort d' obturation du briquet de la figure 1 ; La figure 4 est une coupe transversale, analogue è la figure 1, d'une autre forme de réalisation.Figure 3 is an exploded perspective view of the control pedal and the lighter shutter spring of Figure 1; Figure 4 is a cross section, similar to Figure 1, of another embodiment.
Les figures 1 , 2 et 3 représentent un briquet dont la face supérieure du corps 1 est percée d'un logement cylindrique 3. dont le fond est pourvu d'un siège de clapet 5, à la base duquel arrive le gaz, par un canal 7. Un brûleur 9 est monté coulissant dans le logement 3. L'extrémité amont de ce brûleur est pourvue d'un joint d'obturation 11. Une pédale de commande d'obturation 13 est montée pivotante autour de deux tétons 15. L'une des extrémités de cette pédale 13 comporte deux dents 17, qui s'engagent dans une rainure circulaire 19 prévue sur le brûleur 9. La partie de cette pédale disposée entre les tétons 15 et l'extrémité que sollicite l'utilisateur du briquet est pourvue latéralement, sur sa portion inférieure, de deux parties en saillie 21.Figures 1, 2 and 3 show a lighter, the upper face of the body 1 is pierced with a cylindrical housing 3. whose bottom is provided with a valve seat 5, at the base of which the gas arrives, through a channel 7. A burner 9 is slidably mounted in the housing 3. The upstream end of this burner is provided with a sealing joint 11. A shutter control pedal 13 is pivotally mounted around two studs 15. The one end of this pedal 13 has two teeth 17, which engage in a circular groove 19 provided on the burner 9. The part of this pedal disposed between the pins 15 and the end which the user of the lighter requests is provided laterally, on its lower portion, of two projecting parts 21.
Un ressort de flexion 25 (lame-ressort) coudé en U , prend appui, d'une part, sur la face supérieure du corps du briquet et, d'autre part, sur la face inférieure de la pédale de commande 13. La branche inférieure de ce ressort est pourvue de deux extensions latérales 27,sur lesquelles prennent respectivement appui les parties 21 de la pédale 13. Lorsque l'utilisateur n'exerce aucune force sur cette pédale 13, le ressort 25 tend à la faire pivoter dans le sens de la flèche 23 et à déplacer le brûleur vers le bas . Le joint de clapet 11 se trouve ainsi appliqué contre le siège de clapet 5 et la valve se trouve en position obturée.A bending spring 25 (leaf spring) bent in a U, bears, on the one hand, on the upper face of the lighter body and, on the other hand, on the lower face of the control pedal 13. The branch lower of this spring is provided with two lateral extensions 27, on which the parts 21 of the pedal 13 respectively bear. When the user exerts no force on this pedal 13, the spring 25 tends to rotate it in the direction arrow 23 and move the burner down. The valve seal 11 is thus applied against the valve seat 5 and the valve is in the closed position.
Lorsque l'utilisateur appuie sur la pédale 13 dans le sens de la flèche 29, à l'encontre du ressort 25, cette pédale pivote autour des tétons 15. Les parties 21 s'abaissent, viennent en contact avec la partie 27 et exercent une contrainte supplémentaire sur le ressort 25, suivant la ligne A-A. Sous l'effet de cette contrainte, sa raideur augmente ainsi brusquement. Ainsi lorsque la pédale 13 est complètement enfoncée, ce qui correspond à la position d'ouverture de la valve d'obturation, la raideur du ressort est maximale et la force de rappel vers la position d'obturation de la valve est également maximale. En revanche, lorsque l'utilisateur relâche la pédale 13, le ressort 25 la déplace en sens opposé à la flèche 23 et, lorsque cesse la contrainte exercée par les butées 21 sur le ressort 25, la raideur du ressort diminue brusquement et reste à sa valeur minimale, lorsque la valve atteint sa position d'obturation. Dans la forme de réalisation de la figure 4, le ressort d'obturation 4-0 est un ressort hélicoïdal de compression, logé dans un puits 42 de la face supérieure du corps 44 du briquet, dont le fond est pourvu d'une partie en saillie formant butée 46. Le ressort 40 prend appui, d'une part, sur le fond du puits 42 et, d'autre part,sur le fond d'un logement 48 prévu dans la pédale de commande 47. Une butée 49 est disposée à l'intérieur du ressort 40 et est solidaire de ce dernier.When the user presses on the pedal 13 in the direction of the arrow 29, against the spring 25, this pedal pivots around the pins 15. The parts 21 are lowered, come into contact with the part 27 and exert a additional stress on spring 25, along line AA. Under the effect of this constraint, its stiffness increases suddenly. So when the pedal 13 is fully depressed, which corresponds to the the shutter valve open position, the spring stiffness is maximum and the restoring force towards the valve shutter position is also maximum. On the other hand, when the user releases the pedal 13, the spring 25 moves it in the opposite direction to the arrow 23 and, when the stress exerted by the stops 21 on the spring 25 ceases, the stiffness of the spring abruptly decreases and remains at its minimum value, when the valve reaches its closed position. In the embodiment of FIG. 4, the closing spring 4-0 is a helical compression spring, housed in a well 42 of the upper face of the body 44 of the lighter, the bottom of which is provided with a part in projection forming a stop 46. The spring 40 bears, on the one hand, on the bottom of the well 42 and, on the other hand, on the bottom of a housing 48 provided in the control pedal 47. A stop 49 is arranged inside the spring 40 and is integral with the latter.
Lorsque l'utilisateur enfonce la pédale 47 et comprime le ressort 40, la butée 49 arrive à un moment donné en contact avec la butée 46.When the user depresses the pedal 47 and compresses the spring 40, the stop 49 arrives at a given moment in contact with the stop 46.
A partir de cet instant, la partie du ressort comprise entre le fond du puits 42 et la butée 49 ne participe plus à l'élasticité du ressort. La longueur utile de celui-ci a donc diminué et, en conséquence, sa raideur a augmenté. Dans ces conditions, le ressort 40 possède, en position d'ouverture, une raideur importante, qui lui confère une force de rappel suffisante pour amener le brûleur en position d'obturation, et une raideur plus faible, c'est-à-dire une souplesse plus importante, lorsque que le brûleur est en position d'obturation, ce qui lui permet de compenser les variations dimensionnelles des pièces constituant la valve. From this moment, the part of the spring between the bottom of the well 42 and the stop 49 no longer participates in the elasticity of the spring. The useful length thereof has therefore decreased and, as a result, its stiffness has increased. Under these conditions, the spring 40 has, in the open position, a high stiffness, which gives it a sufficient return force to bring the burner into the closed position, and a lower stiffness, that is to say greater flexibility, when the burner is in the closed position, which allows it to compensate for the dimensional variations in the parts constituting the valve.
