En référence à ces dessins, le dispositif comporte: le filtre d'air(1),situé au commençement du tuyau vertical d'admission(2),qui est pourvu intérieurement d'une soupape
d'admission(3) ,laquelle est située en bas, tout prés du soufflet(4),
le soufflet étant muni d'un ressort hélicoidal (5) situé
centralement. With reference to these drawings, the device comprises: the air filter (1), situated at the beginning of the vertical intake pipe (2), which is internally provided with a valve
intake (3), which is located at the bottom, close to the bellows (4),
the bellows being provided with a helical spring (5) located
centrally.
A la continuité du soufflet(4) se trouve le tuyau horizontal d'évacuation(6),prévu d'une soupape d'évacuation (7), ce tuyau se finissant avec des petits orifices (7c) d'évacuation de l'air, ainsi liberé avec pression. To the continuity of the bellows (4) is the horizontal discharge pipe (6), provided with a discharge valve (7), this pipe ending with small orifices (7c) for evacuation of the air , thus released with pressure.
Le filtre d'air(1),représenté dans la figure 1 comprend:
- un manchon du caoutchouc (la) et un matériel filtrant (lob) comme feutre ou un autre matériel filtrant.The air filter (1), shown in Figure 1 comprises:
- a sleeve of rubber (la) and a filter material (lob) as felt or other filtering material.
Le tuyau d'admision(2),représenté dans la figure numero 2, fait la liaison entre le filtre d'air(1)et la soupape d'admision(3). The inlet pipe (2), shown in figure 2, is the connection between the air filter (1) and the inlet valve (3).
Il est cofectionné du caoutchouc. It is made of rubber.
La soupape d'admission(3)est fixée à l'intérieur du tuyau vértical d'admission(2) et elle est confectionnée d'un mélange de caoutchouc et plastique. The inlet valve (3) is fixed inside the intake pipe (2) and is made of a mixture of rubber and plastic.
Lasoupape(3)contient à l'intérieur un canal avec conicité (3a) et une bille de polystiren(3b). Lasoupape (3) contains inside a channel with conicity (3a) and a ball of polystyrene (3b).
Dés la soupape(3),représenté dans la figure numéro 2 ,dans le tuyau d'admission, commence le tuyau horizontal d'évacuation(6), muni à l'autre extrémité, de la soupape d'évacuation(7) et représenté avec la soupape et ses orifices dans la figure numéro 3. From the valve (3), shown in figure 2, in the intake pipe, begins the horizontal discharge pipe (6), provided at the other end, with the discharge valve (7) and shown with the valve and its orifices in figure 3.
La soupape (7) assure l'évacuation de l'air de ventilation à partir d'une valeur de la pression de l'air du tuyau horizontal (6) établie antérieurement. The valve (7) vents the ventilation air from an air pressure value of the previously established horizontal pipe (6).
Cette soupape présente un manchon de caoutchouc (7a),un orifice d'obturation(7b) et quatre orifices d'évacuation (7c). This valve has a rubber sleeve (7a), a closure port (7b) and four discharge ports (7c).
Le tuyau horizontal d'évacuation(6) se fini avec ces orifices qui assurent la distribution de l'air de ventilation fourni par le systéme qui réalise le pompage artificiel et conduit l'air du niveau du talon jusqu'au niveau des doigts du pied. The horizontal discharge pipe (6) is finished with these holes which ensure the distribution of the ventilation air provided by the system which performs the artificial pumping and conducts the air from the level of the heel to the level of the toes .
Le soufflet(4),représenté dans la figure 4 ,est fermé et confe-e- tionné d'une surface caoutchoutée ou du caoutchouc mince, ayant fixé à l'intérieur un ressort hélicoidal(5)centrale et confectionné du fil d'acier. Ce ressort, en état de tension,pendant le fonftionenent
du système, s'enfouit dans la masse du soufflet.The bellows (4), shown in FIG. 4, is closed and is provided with a rubberized surface or thin rubber, having fixed inside a central helical spring (5) and made of steel wire . This spring, in a state of tension, during the fonftionenent
of the system, bury itself in the mass of the bellows.
Le principe de fonctionnement de ce dispositif est représenté par le pompage alternatif de l'air, produit par le mouvement du talon du pied pendant la marche. The principle of operation of this device is represented by the alternative pumping of air, produced by the movement of the heel of the foot during walking.
Au début,le soufflet(4) se trouve en état de repos et il est rempli de l'air dans son volume entier. At first, the bellows (4) is in a state of rest and is filled with air in its entire volume.
C'est la situation qui caractérise l'état avant de l'introduc
tion du pied dans la chaussure munie de ce dispositif.This is the situation that characterizes the state before the introduc
foot in the shoe provided with this device.
Au moment de l'introduction du pied dans cette chaussure, le ressort(5) est mis en état de tension et il provoque la diminution du volume du soufflet (4). Encet état,l'air du soufflet(4)est poussé avec pression. At the time of introduction of the foot in this shoe, the spring (5) is put in a state of tension and it causes the decrease of the volume of the bellows (4). In state condition, the air of the bellows (4) is pushed with pressure.
Il ferme la soupape d'admission(3) et il prend la direction permise, du tuyau d'évacuation(6),aprés il recontre la soupape d'évacuation(7)qui s'ouvre au moment ou' la valeur de la pression de l'air du tuyau (6),en augmentant, arrive à la valeur obtenue par des calculs. It closes the intake valve (3) and it takes the permitted direction of the discharge pipe (6), after it meets the evacuation valve (7) which opens at the moment when the value of the pressure the air of the pipe (6), increasing, arrives at the value obtained by calculations.
Au moment de la levéedu pied pendant la marche, le ressort(5) se détend grâce à l'energie potentielle accumulée antérieurement, enétat de tension, le volume du soufflet commence à augmenter et, à la suite, il a lieu la création d'une dépression dont l'effet ctest l'aspiration de l'air frais et filtré par l'ouverture de la soupape d'admission. When the foot is lifted during walking, the spring (5) relaxes thanks to the potential energy accumulated previously, in a state of tension, the volume of the bellows begins to increase and, as a result, the creation of a depression whose effect is the suction of fresh air and filtered by the opening of the intake valve.
Le soufflet s'est ainsi rempli de l'air de ventilation et, quand le talon descend , il exerce une pression sur celui-ci, par laquelle détermine la diminution de son volume et la fermeture de la soupape d'admission(3)
L'air de ventilation est obligé de suivre la direction du tube d'évacuation(6) et il arrive à la soupape(7), -cette condition étant concrétisé dans la nécessité de surmonter la résistence opposée par le manchon de caoutchouc(7a),résistence dont la valeur est choisie relativement à la valeur de la pression de l'air avant-determinée. The bellows are thus filled with the ventilation air and, when the heel descends, it exerts a pressure on it, by which determines the decrease of its volume and the closing of the intake valve (3)
The ventilation air is obliged to follow the direction of the evacuation tube (6) and it reaches the valve (7), -this condition being concretized in the need to overcome the opposite resistance by the rubber sleeve (7a) , resistance whose value is chosen relative to the value of the air pressure before-determined.
Ces calculs sont déterminés d'un certain façon pour que la soupape(7)d'évacuationpuisse éliminer l'air de ventilation à une pression d'une valeur plus élevée, ayant comme but la provocation d'une élimination forcée du l'air propre et frais qui pousse à l'extérieur l'air vicié. These calculations are determined in a certain way so that the discharge valve (7) can remove the ventilation air at a higher value pressure, with the aim of causing a forced removal of the clean air and fresh that grows outside the stale air.
Les quatre orifices d'aération (7c) sont placés entre tous les deux doigts du pied pour assurer une aire de dif
fusion , une extension suffisante de l'effet de ventilation.The four ventilation holes (7c) are placed between all the two toes of the foot to provide a breathing area.
fusion, a sufficient extension of the ventilation effect.
A titre d'exemple non-limitatif , les dimensions peuvent être les suivantes
- le diamètre des tuyaux d'admission (2) et d'évacu ation (6) de 5 mm
- le diamètre du fil d'acier du ressort hélicoidal (5) d'un mm
Toutes les autres dimensions sont variables en fonction de la grandeur de la chaussure As a non-limiting example, the dimensions may be as follows
- the diameter of the inlet (2) and outlet (6) pipes of 5 mm
- the diameter of the steel wire of the helical spring (5) of one mm
All other dimensions vary depending on the size of the shoe
