Description

La présente invention concerne une chaussure de ski alpin ou de randonnée équipée d'une source d'énergie à combustible liquide ou gazeux alimentant un dispositif de chauffage logé dans la chaussure.The present invention relates to an alpine or touring ski boot equipped with a source of energy using liquid or gaseous fuel supplying a heating device housed in the boot.

On connaît déjà des chaussures de ski dans lesquelles sont incorporés, dans le but d'améliorer le confort du porteur, des dispositifs de chauffage soit du type électrique à résistance chauffante soit du type à combustible liquide ou gazeux qui utilisent dans ce cas un réservoir de combustible et un brûleur logés dans la chaussure. Les dispositifs de chauffage à combustible liquide ou gazeux présentent l'avantage, par rapport aux dispositifs électriques, de permettre d'obtenir une plus grande autonomie et d'assurer pendant une période de temps relativement longue la température de confort désirée à l'intérieur de la chaussure.Ski boots are already known in which are incorporated, in order to improve the comfort of the wearer, heating devices either of the electric type with heating resistance or of the liquid or gaseous fuel type which in this case use a storage tank. fuel and a burner housed in the shoe. Liquid or gaseous fuel heating devices have the advantage, compared to electrical devices, of making it possible to obtain greater autonomy and of ensuring for a relatively long period of time the desired comfort temperature inside the shoe.

En ce qui concerne les dispositifs à chauffage électrique le brevet US-A-3 977 093, décrit une chaussure équipée d'une source d'énergie électrique alimentant un dispositif de chauffage électrique par l'intermédiaire d'un interrupteur marche-arrêt actionné par la pression du pied engagé dans la chaussure. Les dispositifs de chauffage utilisant un combustible liquide, tels que décrits, par exemple, dans les brevets IT-1 136 269 et FR-A-2 080 146, comportent généralement un brûleur à combustible liquide rechargeable lequel est disposé sous une plaque de diffusion de la chaleur incorporée dans la semelle de la chaussure de manière à s'étendre le plus près possible du pied du porteur de la chaussure. D'autres dispositifs de chauffage qui utilisent un combustible gazeux comprennent un réservoir de gaz alimentant à travers une vanne un brûleur catalytique tous ces éléments étant également logés en totalité dans la semelle de la chaussure. De tels dispositifs de chauffage à combustible gazeux sont décrits par exemple dans le modèle d'utilité italien 196850 et dans la demande de brevet internationale W086/05663. Ces dispositifs de chauffage à combustible gazeux sont du type à réservoir de gaz rechargeable et il est nécessaire par conséquent de prévoir dans la semelle de la chaussure qui contient le réservoir un orifice à travers lequel le réservoir de gaz interne peut être raccordé à une source de recharge en gaz externe.With regard to electrically heated devices, patent US Pat. No. 3,977,093 describes a shoe fitted with a source of electrical energy supplying an electric heating device via an on-off switch actuated by the pressure of the foot engaged in the shoe. Heating devices using liquid fuel, as described, for example, in patents IT-1,136,269 and FR-A-2,080,146, generally include a rechargeable liquid fuel burner which is arranged under a diffusion plate of the heat incorporated into the sole of the shoe so as to extend as close as possible to the foot of the wearer of the shoe. Other heaters that use gaseous fuel include a gas tank supplying a catalytic burner through a valve all these elements also being housed entirely in the sole of the shoe. Such gaseous fuel heating devices are described for example in the Italian utility model 196850 and in international patent application WO86 / 05663. These gaseous fuel heating devices are of the refillable gas tank type and it is therefore necessary to provide in the sole of the shoe which contains the tank an orifice through which the internal gas tank can be connected to a source of external gas recharge.

Les dispositifs de chauffage connus à combustible liquide ou gazeux, présentent l'inconvénient qu'une fois le chauffage mis en marche, l'arrêt de ce chauffage ne peut être obtenu que par intervention manuelle du porteur de la chaussure. Autrement dit celui-ci doit penser à couper le chauffage lorsqu'il quitte sa chaussure et il peut évidemment arriver qu'il oublie de procéder à cette manoeuvre, ce qui se traduit alors par une poursuite du chauffage de la chaussure déchaussée, d'où un épuisement rapide de la source d'énergie utilisée et un gaspillage de cette énergie.The known heating devices for liquid or gaseous fuel have the disadvantage that once the heating is started, the stopping of this heating can only be obtained by manual intervention by the wearer of the shoe. In other words, the latter must think of cutting the heating when he leaves his shoe and it can obviously happen that he forgets to carry out this maneuver, which then results in a continuation of the heating of the bare shoe, hence a rapid exhaustion of the energy source used and a waste of this energy.

La présente invention vise à remédier à ces inconvénients en procurant une chaussure pourvue de moyens provoquant automatiquement la coupure de l'alimentation en combustible aussitôt que le porteur de la chaussure dégage son pied de celle-ci.The present invention aims to remedy these drawbacks by providing a shoe provided with means that automatically cut off the fuel supply as soon as the wearer of the shoe releases his foot from the latter.

A cet effet est prévue une chaussure de ski alpin ou de randonnée équipée d'une source d'énergie à combustible liquide ou gazeux alimentant un dispositif de chauffage et comprenant un dispositif commandant un organe d'alimentation du dispositif de chauffage branché entre la source d'énergie et le dispositif de chauffage, caractérisée en ce qu'elle comprend, à l'intérieur de la chaussure, des moyens sensibles à la pression exercée par le pied sur la semelle interne de la chaussure et des moyens de liaison mécanique entre le dispositif commandant l'organe d'alimentation du dispositif de chauffage et les moyens sensibles à la pression exercée par le pied afin d'autoriser l'ouverture de l'organe d'alimentation en combustible uniquement lorsque la chaussure est chaussée et de provoquer automatiquement la fermeture de cet organe d'alimentation aussitôt que la chaussure est déchaussée.For this purpose, an alpine ski or touring boot is provided, equipped with a source of energy using liquid or gaseous fuel supplying a heating device and comprising a device controlling a supply member of the heating device connected between the source d energy and heating device, characterized in that it comprises, inside the shoe, means sensitive to the pressure exerted by the foot on the inner sole of the shoe and means for mechanical connection between the device controlling the member supplying the heating device and the means sensitive to the pressure exerted by the foot in order to authorize the opening of the fuel supply member only when the shoe is fitted and to automatically cause the closure of this supply member as soon as the shoe is removed.

De préférence les moyens détectant la présence du pied dans la chaussure sont sensibles à la pression exercée par le pied sur la samelle interne de la chaussure et cette détection de la pression est transmise mécaniquement au dispositif commandant l'organe d'alimentation de l'ensemble chauffant en énergie.Preferably the means detecting the presence of the foot in the shoe are sensitive to the pressure exerted by the foot on the inner samelle of the shoe and this pressure detection is transmitted mechanically to the device controlling the power supply member of the heating assembly.

La chaussure à tige suivant l'invention qui peut être une chaussure de ski alpin ou de randonnée est pourvue d'un dispositif de chauffage qui dans le cas de la forme d'exécution non limitative présentement décrite, est du type à gaz combustible. Toutefois l'invention s'appliquerait de la même façon à une chaussure pourvue d'un dispositif de chauffage électrique ou à combustible liquide. Le dispositif de chauffage comprend un ensemble chauffant 1 qui est logé dans un évidement de forme appropriée prévu dans la partie supérieure de la semelle 2 de la chaussure. Cet ensemble chauffant 1 comprend un brûleur 3 fixé par exemple par soudage, sous une plaque de diffusion de la chaleur 4 elle même placée sous la semelle interne 5 de la chaussure afin de pouvoir chauffer le pied du skieur par grand froid. Le bruleur 3 est relié à un tube d'alimentation en gaz 7 et à proximité du bruleur 3 est disposée une électrode 8 faisant partie d'un dispositif d'allumage par exemple du type piézo électrique, auquel elle est raccordée par un conducteur 9.The shoe with an upper according to the invention, which can be an alpine ski or touring boot, is provided with a heating device which, in the case of the non-limiting embodiment presently described, is of the combustible gas type. However, the invention would apply in the same way to a shoe provided with an electric or liquid fuel heating device. The heating device comprises a heating assembly 1 which is housed in a suitably shaped recess provided in the upper part of the sole 2 of the shoe. This heating assembly 1 comprises a burner 3 fixed for example by welding, under a heat diffusion plate 4 itself placed under the inner sole 5 of the boot so as to be able to heat the skier's foot in very cold weather. The burner 3 is connected to a gas supply tube 7 and near the burner 3 is arranged an electrode 8 forming part of an ignition device for example of the piezoelectric type, to which it is connected by a conductor 9.

L' ensemble chauffant 1 est alimenté en gaz à partir d'une cartouche de gaz combustible interchangeable 11 qui est maintenue dans un logement prévu dans la partie postérieure de la tige 12 de la chaussure, à l'intérieur de celle-ci. La cartouche de gaz 11 est disposée verticalement avec son orifice de sortie du gaz dirigé vers le bas. Dans la description qui va suivre on considérera que le sens "vertical" est celui suivant lequel s'étend la tige 12 alors qu'en fait la paroi postérieure de cette tige est légèrement inclinée vers l'avant. La cartouche de gaz 11 est raccordée, à son extrémité inférieure, à un organe d'alimentation 13 constitué par un ensemble formant robinet et détendeur dont l'organe de commande d'ouverture et de fermeture est constitué par un doigt 14 faisant saillie à l'extérieur du corps du robinet 13 et mobile dans une lumière verticale de ce corps. Le doigt 14 est repoussé vers le bas, en direction de sa position d'ouverture, par un ressort de rappel 14a logé à l'intérieur du robinet détendeur 13. Le doigt 14 de commande du robinet 13 est actionné par une patte 15 faisant partie d'un dispositif 16 de commande de l'alimentation en gaz. Ce dispositif 16 agit également sur un poussoir 17 d'un allumeur 18, par exemple du type piézo électrique, qui est relié par le conducteur électrique 9, à l'électrode 8 afin de produire une étincelle d'allumage.The heating assembly 1 is supplied with gas from an interchangeable fuel gas cartridge 11 which is held in a housing provided in the rear part of the upper 12 of the shoe, inside the latter. The gas cartridge 11 is arranged vertically with its gas outlet opening facing downwards. In the description which follows, it will be considered that the "vertical" direction is that in which the rod 12 extends, when in fact the rear wall of this rod is slightly inclined towards the front. The gas cartridge 11 is connected, at its lower end, to a supply member 13 consisting of a valve and regulator assembly, the opening and closing control member of which is constituted by a finger 14 projecting from the exterior of the valve body 13 and movable in a vertical lumen of this body. Finger 14 is pushed down, towards its open position, by a return spring 14a housed inside the pressure reducing valve 13. The finger 14 for controlling the valve 13 is actuated by a lug 15 forming part of a device 16 for controlling the supply of gas. This device 16 also acts on a pusher 17 of an igniter 18, for example of the piezoelectric type, which is connected by the electrical conductor 9, to the electrode 8 in order to produce an ignition spark.

Dans la forme d'exécution non limitative représentée sur la figure 1 de dispositif 16 de commande de l'alimentation en gaz qui agit sur le robinet 13, comprend deux platines sensiblement verticales, adjacentes l'une à l'autre, contenues dans des plans verticaux et longitudinaux, à savoir une platine de commande manuelle 19 relativement de petite hauteur, et une platine 21 d'actionnement du robinet 13, de plus grande hauteur, s'étendant à la fois au dessus et au dessous de la platine 19. La platine 21 d'actionnement du robinet 13, de forme générale rectangulaire, porte à sa partie inférieure, la patte 15 s'étendant sous le doigt 14 et au contact de celui-ci. La platine 19 de commande manuelle présente sensiblement la forme d'un C ouvert vers l'arrière et elle comprend une âme verticale 19a prolongée à ses deux extrémités, respectivement par deux ailes inférieure 19b et supérieure 19c. L'aile inférieure 19b sert à actionner le poussoir 17 de l'allumeur piézo électrique 18 et elle est logée entre la surface supérieure de ce poussoir 17 et une saillie interne 22 de la paroi postérieure de la tige de la chaussure. L'aile supérieure 19c de la platine de commande manuelle 19 s'étend à l'extérieur de la paroi postérieure de la tige 12, en passant à travers une lumière 23 allongée dans le sens vertical. A l'extrémité externe de cette aile 19c est fixé un bouton de commande 24. Par ailleurs la platine 21 est sollicitée constamment vers le haut par un ressort de compression 25 prenant appui sur la face supérieure de la saillie interne 22.In the nonlimiting embodiment shown in FIG. 1 of a device 16 for controlling the gas supply which acts on the valve 13, comprises two substantially vertical plates, adjacent to each other, contained in planes vertical and longitudinal, namely a manual control plate 19 relatively small, and a plate 21 for actuating the valve 13, of greater height, extending both above and below the plate 19. The plate 21 for actuating the tap 13, of generally rectangular shape, carries at its lower part, the tab 15 extending under the finger 14 and in contact with the latter. The plate 19 for manual control has substantially the shape of a C open towards the rear and it comprises a vertical core 19a extended at its two ends, respectively by two lower wings 19b and upper 19c. The lower wing 19b is used to actuate the pusher 17 of the piezoelectric igniter 18 and it is housed between the upper surface of this pusher 17 and an internal projection 22 of the rear wall of the shoe upper. The upper wing 19c of the manual control plate 19 extends outside the rear wall of the rod 12, passing through a slot 23 elongated in the vertical direction. At the outer end of this wing 19c is fixed a control button 24. Furthermore, the plate 21 is constantly stressed upwards by a compression spring 25 bearing on the upper face of the internal projection 22.

Les deux platines 19 et 21 sont accouplées l'une à l'autre par des moyens permettant un mouvement vertical relatif de la platine de commande manuelle 19 par rapport à la platine d'actionnement 21. Plus particulièrement l'âme 19a de la platine de commande manuelle 19 porte deux ergots 26, alignés dans la direction verticale et qui sont respectivement engagés dans des lumières 27 qui sont ménagées dans la platine d'actionnement du robinet 21 et qui sont alignées dans la direction verticale.The two plates 19 and 21 are coupled to each other by means allowing relative vertical movement of the manual control plate 19 relative to the actuating plate 21. More particularly the core 19a of the manual control plate 19 carries two lugs 26, aligned in the vertical direction and which are respectively engaged in slots 27 which are formed in the actuating plate of the tap 21 and which are aligned in the vertical direction.

La platine de commande manuelle 19 comprend également, à sa partie supérieure, une patte 19d s'étendant vers le haut et agissant sur un cliquet 28 qui est articulé sur la partie supérieure de la platine 21 d'actionnement du robinet, autour d'un axe horizontal et transversal 29. Ce cliquet 28 est réalisé sous la forme d'un levier à deux branches formant un angle aigu et s'étendant en direction de la paroi postérieure de la tige 12. La branche inférieure 28a du cliquet 28 est en contact, à son extrémité, avec l'extrémité supérieure de la patte d'actionnement 19d et la branche supérieure 28b de ce cliquet s'étend vers le haut jusqu'à la paroi postérieure de la tige 12. Le cliquet 28 est sollicité dans le sens des aiguilles d'une montre par un ressort 31, si bien que sa branche supérieure 28b est repoussée constamment en direction de la paroi postérieure de la tige 12.The manual control plate 19 also comprises, at its upper part, a tab 19d extending upwards and acting on a pawl 28 which is articulated on the upper part of the plate 21 for actuating the tap, around a horizontal and transverse axis 29. This pawl 28 is produced in the form of a lever with two branches forming an acute angle and extending in the direction of the rear wall of the rod 12. The lower branch 28a of the pawl 28 is in contact , at its end, with the upper end of the actuating tab 19d and the upper branch 28b of this pawl extends upwards to the rear wall of the rod 12. The pawl 28 is biased in the direction clockwise by a spring 31, so that its upper branch 28b is constantly pushed back towards the rear wall of the rod 12.

Le dispositif 16 de commande de l'alimentation en gaz comprend par ailleurs un coulisseau 32 (figure 5), ayant la forme d'un U inversé, qui est monté mobile verticalement le long de la face interne de la paroi postérieure de la tige 12. Ce coulisseau 32 comprend une âme supérieure horizontale et transversale 32a qui est prolongée vers le bas par deux ailes latérales 32b et 32c. Le bord inférieur 32d de l'âme 32a constitue une butée mobile pour l'extrémité supérieure de la branche supérieure 28b du cliquet 28. Ce bord inférieur 32d est découpé, dans sa partie centrale, d'une encoche 32e ouverte vers le bas et dans laquelle peut venir s'engager une dent 33 solidaire de la face interne de la paroi postérieure de la tige 12. Cette dent 33 présente sensiblement une forme de triangle rectangle dont le côté supérieur 33a, constituant l'un des côtés de l'angle droit sert de butée pour le coulisseau 32 dans son mouvement vers le bas. L'hypothénuse 33b de la dent triangulaire 33 s'étend vers le bas et elle forme une rampe de dégagement pour le cliquet 28.The device 16 for controlling the gas supply also comprises a slide 32 (FIG. 5), in the form of an inverted U, which is mounted vertically movable along the internal face of the rear wall of the rod 12 This slide 32 comprises an upper horizontal and transverse core 32a which is extended downwards by two lateral wings 32b and 32c. The lower edge 32d of the core 32a constitutes a movable stop for the upper end of the upper branch 28b of the pawl 28. This lower edge 32d is cut, in its central part, with a notch 32e open downwards and in which can engage a tooth 33 integral with the internal face of the rear wall of the rod 12. This tooth 33 has substantially the shape of a right triangle whose upper side 33a, constituting one of the sides of the right angle serves as a stop for the slide 32 in its movement towards the bottom. The hypotenuse 33b of the triangular tooth 33 extends downwards and forms a clearance ramp for the pawl 28.

A leurs extrémités inférieures les deux ailes verticales 32b,32c du coulisseau 32 sont reliées, par l'intermédiaire d'une tringlerie 34, à un levier 35 sensiblement horizontal logé dans la semelle 2 de la chaussure. Ce levier 35 est articulé, à son extrémité antérieure, autour d'un axe horizontal et transversal 36 et il est sollicité vers le haut par un ressort 37. Ce levier 35 est accroché à son extrémité postérieure, à la tringlerie de liaison 34. Sur ce levier 35 prend appui, par l'intermédiaire d'un plot 5a, la partie extrême postérieure de la semelle interne 5.At their lower ends, the two vertical wings 32b, 32c of the slide 32 are connected, by means of a linkage 34, to a substantially horizontal lever 35 housed in the sole 2 of the shoe. This lever 35 is articulated, at its front end, about a horizontal and transverse axis 36 and it is urged upwards by a spring 37. This lever 35 is hooked at its rear end, to the linkage link 34. On this lever 35 is supported, by means of a stud 5a, the rear posterior part of the inner sole 5.

Lorsque le pied du skieur est engagé dans la chaussure, comme il est représenté schématiquement en trait mixte sur la figure 1. une pression, illustrée par la flèche P. s'exerce sur la semelle interne 5 de cette chaussure et la partie extrême postérieure de celle-ci est repoussée vers le bas et il en est de même du levier 35. Le pivotement du levier 35 vers le bas est transmis au coulisseau 32. par l'intermédiaire de la tringlerie 34, et ce coulisseau 32 vient alors occuper sa position extrême inférieure, telle que représentée sur la figure 2, dans laquelle son âme horizontale 32a vient en butée contre le côté supérieure 33a de la dent 33, qui est alors engagée dans le fond de l'encoche 32e. Le cliquet porte alors librement, par l'extrémité supé rieure de sa branche supérieure 28b. sur la face verticale interne de l'âme 32a comme il est représenté sur la figure 2. Dans cette position le dispositif 16 de commande d'alimentation en gaz se trouve normalement en position de fermeture. La platine 21 d'actionnement du robinet 13 est en effet repoussée, par le ressort 25, en position extrême supérieure et sa patte inférieure 15 maintient le doigt 14 d'actionnement du robinet 13, dans sa position extrême supérieure correspondant à la fermeture de ce robinet. Par ailleurs la platine de commande manuelle 19 est également repoussée dans sa position extrême supérieure par l'intermédiaire de la platine 21, position dans laquelle son aile inférieure 19b est en contact avec la saillie 22.When the skier's foot is engaged in the boot, as shown diagrammatically in a broken line in FIG. 1. a pressure, illustrated by the arrow P. is exerted on the inner sole 5 of this boot and the rear posterior part of the latter is pushed downwards and the same is true of the lever 35. The pivoting of the lever 35 downwards is transmitted to the slider 32. by means of the linkage 34, and this slider 32 then occupies its position lower end, as shown in FIG. 2, in which its horizontal core 32a abuts against the upper side 33a of the tooth 33, which is then engaged in the bottom of the notch 32e. The pawl then carries freely, by the upper end of its upper branch 28b. on the internal vertical face of the core 32a as shown in FIG. 2. In this position the device 16 for controlling the gas supply is normally in the closed position. The plate 21 for actuating the valve 13 is in fact pushed back, by the spring 25, into the upper extreme position and its lower tab 15 maintains the finger 14 for actuating the valve 13, in its upper upper position corresponding to the closing of this tap. Furthermore, the manual control plate 19 is also pushed back into its upper extreme position by means of the plate 21, position in which its wing lower 19b is in contact with the projection 22.

Si le skieur désire mettre en marche le dispositif de chauffage, il appuie vers le bas sur le bouton de commande 24, ce qui a pour effet de provoquer la descente des deux platines 19 et 21, à l'encontre de l'action du ressort de rappel 25. La descente de la patte 15 libère le doigt 14 qui est alos repoussé en position inférieure d'ouverture par le ressort 14a si bien que le robinet 13 s'ouvre et que le gaz peut s'écouler en direction du brûleur 3. En poursuivant temporairement le mouvement de descente du bouton de commande 24 au-delà de la position intermédiaire d'ouverture la platine 19 repousse par son aile inférieure 19b, le poussoir 17 de l'allumeur piézo-électrique 18, ce qui provoque alors la production d'une étincelle à l'électrode 8 pour allumer le gaz. Après relâchement du bouton de commande 24. celui-ci se replace automatiquement sous l'action du ressort de rappel 25, dans la position d'ouverture intermédiaire qui est représentée sur la figure 1. Il est retenu dans cette position du fait que le cliquet 28 se trouve alors verrouillé, ainsi qu'il est représenté sur la figure 3. En effet, au cours du mouvement de descente de la platine 21 d'actionnement du robinet 13, la branche supérieure 28b du cliquet 28 glisse sur la face interne de l'âme supérieure 32a du coulisseau 32 et lorsqu'elle arrive juste en dessous du bord inférieur 32d de cette âme 32a, le cliquet 28 pivote dans le sens des aiguilles d'une montre, autour de son axe 29, sous l'action du ressort 31, l'extrémité de la branche supérieure 28b du cliquet 28 vient s'engager sous le bord inférieur 32d de l'âme 32a et elle est ainsi immobilisée par ce dernier. Le cliquet 28 étant ainsi verrouillé sa branche inférieure 28a constitue une butée fixe contre laquelle est appliquée la patte supérieure 19d de la platine 19, en empêchant ainsi le retour automatique des deux platines 19 et 21 en position de fermeture. Le skieur peut toutefois couper à tout moment le chauffage, en tirant le bouton de commande 24 vers le haut. Dans ce cas la patte 19d force sur le cliquet 28 et le fait pivoter dans le sens inverse des aiguilles d'une montre autour de l'axe 29 en dégageant ainsi la branche supérieure 28b du bord 32d. A partir de ce moment les deux platines 19,21 peuvent coulisser automatiquement vers le haut, sous l'action du ressort de rappel 25, pour passer en position de fermeture de l'alimentation du gaz.If the skier wishes to turn on the heating device, he presses down on the control button 24, which has the effect of causing the descent of the two plates 19 and 21, against the action of the spring return 25. The descent of the tab 15 releases the finger 14 which is then pushed back into the lower open position by the spring 14a so that the valve 13 opens and the gas can flow towards the burner 3 By temporarily continuing the downward movement of the control button 24 beyond the intermediate open position the plate 19 pushes back by its lower wing 19b, the pusher 17 of the piezoelectric igniter 18, which then causes the production of a spark at electrode 8 to ignite the gas. After releasing the control button 24. the latter is automatically replaced under the action of the return spring 25, in the intermediate opening position which is shown in FIG. 1. It is retained in this position because the pawl 28 is then locked, as shown in FIG. 3. Indeed, during the downward movement of the plate 21 for actuating the valve 13, the upper branch 28b of the pawl 28 slides on the internal face of the upper core 32a of the slide 32 and when it arrives just below the lower edge 32d of this core 32a, the pawl 28 pivots clockwise around its axis 29, under the action of the spring 31, the end of the upper branch 28b of the pawl 28 engages under the lower edge 32d of the core 32a and it is thus immobilized by the latter. The pawl 28 being thus locked its lower branch 28a constitutes a fixed stop against which the upper tab 19d of the plate 19 is applied, thereby preventing the automatic return of the two plates 19 and 21 to the closed position. The skier can however switch off the heating at any time by pulling the control button 24 upwards. In this case, the tab 19d forces on the pawl 28 and makes it pivot anticlockwise around the axis 29, thus freeing the branch upper 28b from edge 32d. From this moment the two plates 19, 21 can slide automatically upwards, under the action of the return spring 25, to pass into the closed position of the gas supply.

D'après la description qui précède on voit que, pour que le cliquet 28 puisse être verrouillé en position et constituer une butée pour maintenir les platines 19 et 21 en position d'ouverture du gaz, il est nécessaire que le coulisseau 32 soit en position basse, autrement dit qu'une pression s'exerce sur la partie postérieure de la semelle interne 5. Par conséquent, si le skieur oublie de couper le chauffage lorsqu'il enlève sa chaussure, la coupure de l'alimentation en gaz du brûleur 3 s'effectue automatiquement aussitôt que le skieur enlève sa chaussure du fait que la semelle interne 5 n'est alors plus soumise à une pression. En effet dans ce cas, le levier 35 pivote vers le haut sous l'action du ressort 37, le coulisseau 32 est déplacé vers le haut, dans la position de repos ou de fermeture illustrée sur la figure 4, et les deux platines 19,21 se déplacent également vers le haut en position extrême supérieure de fermeture du fait que le cliquet 28 n'est plus verrouillé. Durant ce mouvement l'extrémité de la branche supérieure 28b du cliquet 28 glisse sur la rampe 33b de la dent 33, ce qui provoque un pivotement du cliquet 28 dans le sens inverse des aiguilles d'une montre autour de l'axe 29, à l'encontre de l'action du ressort 31.From the above description, it can be seen that, so that the pawl 28 can be locked in position and constitute a stop to keep the plates 19 and 21 in the gas opening position, it is necessary for the slide 32 to be in position. low, in other words a pressure is exerted on the rear part of the inner sole 5. Consequently, if the skier forgets to switch off the heating when he takes off his shoe, the gas supply to the burner 3 is cut off takes place automatically as soon as the skier removes his shoe because the insole 5 is no longer subjected to pressure. In this case, the lever 35 pivots upwards under the action of the spring 37, the slide 32 is moved upwards, in the rest or closed position illustrated in FIG. 4, and the two plates 19, 21 also move upwards in the extreme upper closed position because the pawl 28 is no longer locked. During this movement the end of the upper branch 28b of the pawl 28 slides on the ramp 33b of the tooth 33, which causes the pawl 28 to pivot in an anti-clockwise direction around the axis 29, at against the action of the spring 31.

La figure 6 illustre une variante d'exécution de l'invention appliquée à une chaussure de ski alpin du type comportant un bas de coque 38 sur lequel est articulé un capot arrière 39, autour d'un axe horizontal et transversal 41. Dans ce cas le verrouillage de la platine 21 d'actionnement du robinet 13, en position d'ouverture, est assuré par un crochet 42 prolongeant vers le bas cette platine et qui s'engage dans la partie extrême supérieure d'un ressort de verrouillage 43 porté par la partie inférieure du capot arrière 39. Ce ressort 43, représenté d'une manière détaillée sur la figure 7, comprend une partie centrale supérieure 43a en forme de ganse, ouverte vers le bas. qui est plane ou qui forme de préférence un dièdre d'angle obtus ouvert vers l'intérieur, comme il est représenté sur le dessin, afin de suivre au mieux la forme du capot arrière 39. Les deux branches latérales de la ganse 43a sont prolongées, à leurs extrémités inférieures, par des enroulements hélicoïdaux coaxiaux 43b et 43c entourant un axe horizontal et transversal 44 porté par la partie inférieure et postérieure du capot arrière 39. Les enroulements hélicoïdaux coaxiaux 43b,43c sont à leur tout prolongés par des branches d'appui coplanaires 43d,43e, formant un angle aigu avec la ganse supérieur 43a. De préférence chacune des branches d'appui 43d,43e a sensiblement la forme d'un U ouvert vers le bas. dont la branche externe s'étend à la fois au-dessus et en dessous de l'axe d'enroulement 44. Les branches d'appui coplanaires 43d,43e sont destinées à venir s'appliquer contre la partie supérieure 45a, escamotable vers le bas, d'un levier 45 sensiblement en forme de L qui comprend une aile inférieure 45b sensiblement horizontale s'étendant vers l'avant, sous la partie extrême postérieure de la semelle interne 5. Un ressort de rappel 46 est logé en-dessous de l'aile horizontale inférieure 45b et ce ressort repousse en permanence cette aile vers le haut. Par ailleurs dans la partie supérieure 45a du levier 45 sont ménagées des lumières 47 qui sont inclinés de haut en bas et d'avant en arrière et dans ces lumières s'étendent des tétons horizontaux et transversaux 48 solidaires du bas de coque 38 pour commander le mouvement du levier 45.FIG. 6 illustrates an alternative embodiment of the invention applied to an alpine ski boot of the type comprising a shell bottom 38 on which a rear cover 39 is hinged, around a horizontal and transverse axis 41. In this case the locking of the plate 21 for actuating the tap 13, in the open position, is ensured by a hook 42 extending downwards this plate and which engages in the upper end part of a locking spring 43 carried by the lower part of the rear cover 39. This spring 43, shown in detail in FIG. 7, comprises an upper central part 43a in the form of a loop, open downwards. which is flat or which preferably forms an obtuse corner dihedral open inwards, as shown in the drawing, in order to best follow the shape of the rear cover 39. The two lateral branches of the strap 43a are extended, at their ends lower, by coaxial helical windings 43b and 43c surrounding a horizontal and transverse axis 44 carried by the lower and rear part of the rear cover 39. The coaxial helical windings 43b, 43c are in their whole extended by coplanar support branches 43d, 43e, forming an acute angle with the upper loop 43a. Preferably each of the support branches 43d, 43e has substantially the shape of a U open towards the bottom. the external branch of which extends both above and below the winding axis 44. The coplanar support branches 43d, 43e are intended to come to bear against the upper part 45a, retractable towards the bottom, of a substantially L-shaped lever 45 which comprises a substantially horizontal lower wing 45b extending forwards, under the rear posterior part of the inner sole 5. A return spring 46 is housed below the lower horizontal wing 45b and this spring permanently pushes this wing upwards. Furthermore in the upper part 45a of the lever 45 are formed lights 47 which are inclined from top to bottom and from front to back and in these lights extend horizontal and transverse pins 48 integral with the bottom of the shell 38 to control the lever movement 45.

Sur la figure 6 le levier 45 est représenté en trait plein dans la position qu'il occupe lorsque la chaussure est chaussée et en trait mixte dans le cas contraire. Par conséquent, lorsque la chaussure est chaussée. la semelle interne 5 qui est soumise à la pression du pied, appuie, par sa partie extrême postérieure. sur l'aile horizontale inférieure 45b du levier 45, ce qui a pour effet de faire descendre ce levier 45, dans son ensemble, de sa position indiquée en trait mixte à sa position indiquée en trait plein. Du fait la liaison entre le bas de coque 38 et le levier 45 réalisée par les lumières glissant sur les tétons 48, ces lumières provoquent, du fait de leur inclinaison, un déplacement de la partie supérieure du levier 45 vers l'extérieur. Dans la position atteinte la face postérieure de la partie supérieur 45a du levier 45 constitue une surface d'appui contre laquelle sont plaquées les branches coplanaires 43d,43e du ressort 43. Ce ressort 43 se trouve ainsi maintenu en position de verrouillage dans laquelle il peut assurer la retenue du crochet 43, lorsque la platine 21 se trouve dans la position basse d'ouverture, et par conséquent le maintien du dispositif de commande d'alimentation en gaz en position d'ouverture. Lors du déchaussage, le ressort 46 repousse l'aile inférieure 45b et l'ensemble du levier 45 vers le haut, ce qui a pour effet de faire passer ce levier dans sa position de repos indiquée en trait mixte. Du fait des lumières 47 et des tétons 48, la face postérieure d'appui de la partie supérieure 45a du levier 45 s'écarte des branches d'appui 43d,43c du ressort 43. Par ailleurs, par suite du mouvement de basculement d'ouverture totale du capot arrière 39, avant que le skieur ne dégage son pied de la chaussure, les branches 43d,43e du ressort 43 viennent en contact avec une saillie externe 50 prévue à la partie inférieure de la paroi postérieure du bas de coque 38. Cette saillie 50 constitue une rampe de dégagement provoquant, lorsque les branches 43d,43e du ressort 43 viennent en contact avec elle, par leurs parties extrêmes inférieures, un pivotement, dans le sens inverse des aiguilles d'une montre, de l'ensemble du ressort 43 autour de l'axe 44 si bien que la ganse 43a du ressort 43 est désolidarisée de sa liaison avec le crochet 42. De ce fait le crochet 42 n'est plus retenu, il échappe alors automatiquement au ressort 43 et le dispositif de commande d'alimentation en gaz revient automatiquement en position de fermeture.In Figure 6 the lever 45 is shown in solid lines in the position it occupies when the shoe is worn and in broken lines in the opposite case. Therefore, when the shoe is worn. the inner sole 5 which is subjected to the pressure of the foot, presses, by its posterior end portion. on the lower horizontal wing 45b of the lever 45, which has the effect of lowering this lever 45, as a whole, from its position indicated in phantom to its position indicated in solid line. Due to the connection between the bottom of the shell 38 and the lever 45 produced by the lights sliding on the pins 48, these lights cause, due to their inclination, a displacement of the upper part of the lever 45 outwards. In the position reached, the rear face of the upper part 45a of the lever 45 constitutes a bearing surface against which the coplanar branches 43d, 43e of the spring 43 are pressed. This spring 43 is thus held in the locking position in which it can ensuring the retention of the hook 43, when the plate 21 is in the low open position, and therefore maintaining the gas supply control device in the open position. During heaving, the spring 46 pushes the lower wing 45b and the lever assembly 45 upwards, which has the effect of causing this lever to pass into its rest position indicated in phantom. Due to the lights 47 and the pins 48, the rear bearing face of the upper part 45a of the lever 45 departs from the bearing branches 43d, 43c of the spring 43. Furthermore, as a result of the tilting movement of total opening of the rear cover 39, before the skier releases his foot from the boot, the branches 43d, 43e of the spring 43 come into contact with an external projection 50 provided at the lower part of the rear wall of the bottom of the shell 38. This projection 50 constitutes a release ramp causing, when the branches 43d, 43e of the spring 43 come into contact with it, by their lower end portions, a pivoting, in the anticlockwise direction, of the whole of the spring 43 around the axis 44 so that the loop 43a of the spring 43 is detached from its connection with the hook 42. As a result the hook 42 is no longer retained, it then automatically escapes the spring 43 and the device power control in gas automatically returns to the closed position.

La coupure automatique de l'alimentation en gaz est également obtenue lors du basculement du capot arrière 39 vers l'arrière autour de l'axe 41, même si le skieur garde alors la chaussure à son pied. En effet au cours de ce mouvement d'ouverture du capot arrière 39 les branches d'appui 43d,43e du ressort 43 glissent le long de la face postérieure et supérieure 45a du levier 45 puis à un certain moment, au cours du mouvement de basculement, elles échappent à cette face en se trouvant placées à distance de la paroi inférieure et postérieure du bas de coque 38 et les branches 43d et 43e du ressort 43 sont là aussi à nouveau sollicitées par la rampe de dégagement 50 lors du basculement du capot arrière 39 en position d'ouverture totale si bien que le ressort de verrouillage 43 est alors libéré ce qui provoque la coupure automatique de l'alimentation en gaz.The automatic cut-off of the gas supply is also obtained during the tilting of the rear cover 39 towards the rear around the axis 41, even if the skier then keeps the boot on. Indeed during this opening movement of the rear cover 39 the support branches 43d, 43e of the spring 43 slide along the rear face and upper 45a of the lever 45 then at a certain moment, during the tilting movement, they escape this face by being placed at a distance from the lower and rear wall of the bottom of the shell 38 and the branches 43d and 43e of the spring 43 there again are again requested by the release ramp 50 during the tilting of the rear cover 39 in the fully open position so that the locking spring 43 is then released which causes the automatic cut off of the gas supply.

La figure 8 représente une variante du dispositif qui vient d'être décrit, variante dans laquelle le levier 45 est articulé autour d'un axe horizontal et transversal 49 prévu à l'extrémité antérieure de sa branche inférieure 45b. Dans ce cas le levier 45 pivote dans un sens ou dans l'autre autour de l'axe 49, soit sous l'action de la semelle interne 5 soit sous celle du ressort de rappel 46.FIG. 8 represents a variant of the device which has just been described, a variant in which the lever 45 is articulated around a horizontal and transverse axis 49 provided at the front end of its lower branch 45b. In this case, the lever 45 pivots in one direction or the other around the axis 49, either under the action of the inner sole 5 or under that of the return spring 46.

Les figures 9,10 et 11 représentent une variante d'exécution du dispositif 16 de commande de l'alimentation en gaz. Dans cette forme d'exécution les deux platines accolées, à savoir la platine de commande manuelle 19 et la platine 21 d'actionnement du robinet 13, sont logées à coulissement vertical dans un support commun 51 fixé à la paroi postérieure de la tige 12. Ce support 51 présente deux ailes latérales opposées 52, s'étendant verticalement par lesquelles il prend appui contre la paroi postérieure de la tige 12 et, entre ces deux ailes 52, un évidement borgne 53 fermé à sa partie inférieure et débouchant dans la face supérieure du support 51. Dans cet évidement 53 est engagé le ressort de compression 25 qui prend appui, à son extrémité inférieure, dans le fond du logement 53 et qui sollicite la platine 21 vers le haut. Le support 51 est percé de part en part, dans sa partie antérieure. d'un trou 54, de section droite horizontale de forme rectangulaire correspondant à la superposition des sections droites rectangulaires des deux platines accolées 19,21 si bien que ces deux platines sont guidées étroitement à coulissement vertical dans le support 51.Figures 9,10 and 11 show an alternative embodiment of the device 16 for controlling the gas supply. In this embodiment, the two adjoining plates, namely the manual control plate 19 and the plate 21 for actuating the valve 13, are housed with vertical sliding in a common support 51 fixed to the rear wall of the rod 12. This support 51 has two opposite lateral wings 52, extending vertically by which it bears against the rear wall of the rod 12 and, between these two wings 52, a blind recess 53 closed at its lower part and opening into the upper face of the support 51. In this recess 53 is engaged the compression spring 25 which bears, at its lower end, in the bottom of the housing 53 and which urges the plate 21 upwards. The support 51 is drilled right through, in its front part. a hole 54, of horizontal cross section of rectangular shape corresponding to the superposition of the rectangular cross sections of the two adjoining plates 19, 21 so that these two plates are closely guided in vertical sliding in the support 51.

Dans la forme d'exécution représentée sur les figures 9 à 11 les moyens permettant un mouvement vertical relatif de la platine de commande manuelle 19 par rapport à la platine d'actionnement 21 comprennent un plot cylindrique 55 logé et immobilisé dans une encoche 56 de même longueur, laquelle est formée dans le bord vertical antérieur de la platine de commande manuelle 19. Le plot 55 fait saillie par rapport à la face de la platine 19 qui est en contact avec l'autre platine 21 et il est engagé dans une lumière verticale correspondante 27 prévue dans la platine 21. La longueur de la lumière 27 est naturellement choisie supérieure à celle du plot 55 afin de permettre le mouvement de coulissement relatif de la platine 19 par rapport à l'autre platine 21.In the embodiment shown in FIGS. 9 to 11, the means allowing relative vertical movement of the manual control plate 19 relative to the actuation plate 21 comprise a cylindrical stud 55 housed and immobilized in a notch 56 likewise length, which is formed in the front vertical edge of the manual control plate 19. The stud 55 projects relative to the face of the plate 19 which is in contact with the other plate 21 and it is engaged in a vertical light corresponding 27 provided in the plate 21. The length of the light 27 is naturally chosen to be greater than that of the stud 55 in order to allow the relative sliding movement of the plate 19 relative to the other plate 21.

Dans la variante d'exécution de l'invention représentée sur la figure 12 l'organe de la platine 19 qui fait saillie dans la lumière 27 de la platine 21 est constitué par une languette 57 qui est découpée dans la platine 19, en restant attenante à celle-ci par l'un de ses côtés, et qui est cambrée de manière à s'étendre dans la lumière 27 de la platine 21. Dans cette forme d'exécution la languette en saillie 57 comprend une partie centrale 57a située dans le plan de la platine 19 et deux ailes latérales 57b qui sont cambrées vers l'extérieur et qui s'engagent dans la lumière 27, si bien que la languette 57 présente en section droite sensiblement la forme d'un oméga.In the alternative embodiment of the invention shown in Figure 12 the member of the plate 19 which projects into the slot 27 of the plate 21 is constituted by a tongue 57 which is cut in the plate 19, remaining attached to the latter by one of its sides, and which is arched so as to extend in the lumen 27 of the plate 21. In this embodiment the protruding tongue 57 comprises a central part 57a located in the plane of the plate 19 and two lateral wings 57b which are arched outwards and which engage in the lumen 27, so that the tongue 57 has in cross section substantially the shape of an omega.

Dans la variante d'exécution de l'invention représentée sur la figure 13 l'organe en saillie dans la lumière 27 de la platine 21 est constitué par une patte 58 qui est découpée dans la platine 19 et qui est cambrée à l'équerre de manière à faire saillie par rapport au plan de la platine 19 et a être engagée dans la lumière 27.In the variant embodiment of the invention shown in FIG. 13, the member projecting into the opening 27 of the plate 21 is constituted by a tab 58 which is cut out in the plate 19 and which is bent at right angles to so as to project from the plane of the plate 19 and to be engaged in the light 27.

Bien que la description qui précéde ait porté sur une chaussure de ski alpin comportant, en tant que dispositif consommateur d'énergie. un dispositif de chauffage, il va de soi que l'invention pourrait s'appliquer également à n'importe quel dispositif consommateur d'énergie. destiné par exemple à exercer une action mécanique automatique.Although the foregoing description has concerned an alpine ski boot comprising, as an energy-consuming device. a heating device, it goes without saying that the invention could also apply to any energy consuming device. intended for example to exert an automatic mechanical action.
