Abstract
Description
L'invention concerne un appareil de scellement ou de perforation ou d'entraínement ou d'enfoncement de tout élément dans un matériau récepteur, du type cloueur, agrafeuse ou marteau, à fonctionnement à gaz.The invention relates to an apparatus for sealing or perforating or driving or driving any element in a material receiver, type nailing, stapling or hammer, gas operated.
Dans un tel appareil, un piston est monté mobile dans un cylindre pour y être propulsé, par l'explosion d'un mélange d'air et d'un gaz combustible injecté, depuis une cartouche, dans une chambre de combustion, et pour entraíner un élément, par exemple de fixation (un clou ou un tampon), ou autre cheville. Outre la sécurité d'appui, qui interdit toute mise à feu quand l'appareil n'est pas en appui contre un matériau récepteur, il est prévu dans ce genre d'appareil un organe, appelé cage, qui, lors de la mise en appui et par l'intermédiaire d'un palpeur pouvant être un guide-tampon mobile, repousse un manchon de chambre jusqu'en butée contre la culasse qui porte la bougie d'allumage destinée à provoquer l'explosion, afin de refermer la chambre de combustion ainsi fermée par ce manchon, la culasse et la tête du piston. La cage et le manchon peuvent être liés l'un à l'autre par vissage. En outre, le recul de la cage s'effectue contre l'action d'un ressort de rappel, pour rappeler l'appareil en position d'ouverture, également en appui contre le cylindre du piston.In such an apparatus, a piston is movably mounted in a cylinder for be propelled by the explosion of a mixture of air and a combustible gas injected from a cartridge into a combustion chamber and for driving an element, for example fixing (a nail or a pad), or other ankle. In addition to support security, which prohibits firing when the apparatus does not bear against a receiving material, it is provided in this kind of device an organ, called cage, which, when putting in support and via a probe that can be a mobile buffer guide, pushes a chamber sleeve to the stop against the bolt the spark plug intended to cause the explosion, in order to close the combustion chamber thus closed by this sleeve, the cylinder head and the head of the piston. The cage and the sleeve can be connected to each other by screwing. In addition, the recoil of the cage is effected against the action of a return spring, to recall the device in the open position, also in support against the cylinder of the piston.
Du fait de la mise en appui de la chambre de combustion contre la culasse, des pressions contraignantes s'exercent sur la culasse lors du fonctionnement d'un tel appareil, notamment parce que des portions de surface de la culasse et du cylindre se font mutuellement face. Et même si dans d'autres appareils, ces pressions néfastes ne s'exercent plus sur la culasse, elles sont reportées sur la cage, ce qui n'est pas forcément mieux.Due to the support of the combustion chamber against the cylinder head, binding pressures are exerted on the cylinder head during the operation of such apparatus, in particular because portions of surface of the cylinder head and cylinder face each other. And even if in other devices, these harmful pressures are no longer exerted on the breech, they are carried on the cage, which is not necessarily better.
L'invention de la présente demande vise à s'affranchir de toute contrainte de pression parasite tant sur la culasse que sur la cage.The invention of the present application aims to overcome all constraints of parasitic pressure on both the cylinder head and the cage.
A cet effet, l'invention concerne un appareil à fonctionnement à gaz, dans lequel, sous l'action de l'explosion d'un mélange d'air et de gaz dans une chambre fermée par l'intermédiaire d'un manchon de chambre et d'une cage lors de la mise en appui de l'appareil, un piston est propulsé dans un cylindre pour entraíner un élément, caractérisé par le fait que le manchon de chambre et le cylindre sont agencés pour que, lors de la fermeture de l'appareil, le manchon de chambre vienne en butée contre le cylindre.For this purpose, the invention relates to a gas-operated apparatus in which which, under the action of the explosion of a mixture of air and gas in a closed chamber via a chamber sleeve and a cage when the device is put in support, a piston is propelled into a cylinder for driving an element, characterized in that the sleeve chamber and the cylinder are arranged so that when closing the the device, the chamber sleeve comes into abutment against the cylinder.
Par élément, il faut entendre soit un clou, un tampon, une cheville, une agrafe ou tout autre élément analogue. By element, it is necessary to hear either a nail, a buffer, an ankle, a staple or any other similar element.
Dans une forme de réalisation de l'appareil de l'invention, la cage et le manchon de chambre sont liés avec jeu en coulissement, pour éviter la propagation des contraintes.In one embodiment of the apparatus of the invention, the cage and the Sleeve sleeve are linked with sliding play, to avoid the propagation of constraints.
Le manchon de chambre peut comporter au moins un patin d'appui, disposé pour venir en butée contre une oreille d'appui du cylindre, au moins une goupille de liaison du manchon de chambre et de la cage et au moins une oreille d'appui d'un ressort d'ouverture, en appui aussi contre une joue du cylindre, et de poussée mutuelle de l'un par l'autre du manchon de chambre et de la cage.The chamber sleeve may comprise at least one support pad, arranged to abut against a bearing lug of the cylinder, at least one connecting pin of the chamber sleeve and the cage and at least one ear support a spring opening, also against a cheek cylinder, and mutual thrust of one by the other of the chamber sleeve and the cage.
Mais le manchon de chambre peut aussi comporter au moins un patin d'appui, de poussée et de liaison disposé pour venir en butée contre une joue d'appui du cylindre en position de fermeture, au moins une goupille de liaison du manchon de chambre, du patin d'appui et de la cage et au moins un ressort d'ouverture de la chambre en butée contre la joue d'appui et le patin d'appui.But the chamber sleeve may also include at least one skate support, thrust and connection arranged to abut against a cheek of the cylinder in the closed position, at least one pin of connection of the chamber sleeve, the support pad and the cage and at least an opening spring of the chamber in abutment against the support cheek and the support pad.
Dans ce cas, il est intéressant que le patin porte un doigt d'appui de section rétrécie agencé pour venir en appui contre la joue du cylindre et recevoir le ressort d'ouverture.In this case, it is interesting that the pad carries a section support finger narrowed arranged to bear against the cheek of the cylinder and receive the opening spring.
L'invention sera mieux comprise à l'aide de la description suivante de deux formes de réalisation de l'appareil de l'invention, en référence au dessin annexé, sur lequel

A l'avant d'une culasse, portant une bougie d'allumage et un moto-ventilateur,
ces éléments de l'appareil n'étant pas représentés, pas plus que
la poignée de préhension et d'actionnement, la cartouche de gaz et le
chargeur d'éléments d'ancrage, l'appareil comporte un manchon de chambre
1, un cylindre 2, à portion avant 3 de section réduite, une cage 4 de
fermeture de chambre et un palpeur 5.At the front of a cylinder head, carrying a spark plug and a fan motor,
these elements of the apparatus not being represented, any more than
the handle and actuation handle, the gas cartridge and the
Anchor loader, the device has a chamber sleeve
1, a
Le palpeur 5, au demeurant classique, est solidaire en translation de la cage,
ici par vis, cage dont une portion avant semi-tubulaire 6 enveloppe l'arrière
du palpeur. La portion avant 6 de la cage 4 se prolonge, vers l'arrière, par
deux bras latéraux 7, 8 dont l'extrémité arrière 9 est coudée vers l'axe 16 de
l'appareil pour former un bec de liaison.The
Les deux bras 7, 8 de la cage s'étendent le long du cylindre 2, à l'extérieur,
jusqu'à la partie antérieure 10 du manchon de chambre 1.The two
Sur sa paroi extérieure, le cylindre 2 porte des oreilles radiales d'appui 11
pour servir de butées au manchon de chambre 1 en position de fermeture,
et, à l'arrière des oreilles d'appui 11, des joues radiales d'appui 12, servant
de butées à des ressorts 13 de rappel de la chambre en position d'ouverture.On its outer wall, the
De façon classique, et c'est pourquoi la description ne sera pas amplement
développée sur ce point, l'arrière 14 du manchon de chambre 1 forme
partiellement la chambre de combustion 15 de l'appareil.In a classic way, and that is why the description will not be amply
developed on this point, the
Dans le cylindre 2 est monté un piston de propulsion 17, avec sa tête 18,
formant aussi en partie la chambre 15, et sa tige de propulsion 19. Le
cylindre comporte un bourrelet arrière 20 dans lequel est ménagée une
gorge de réception d'un joint 21 destiné, en position de fermeture, à assurer,
avec le manchon de chambre 1, l'étanchéité avant de la chambre de
combustion 15.In the
A cet effet, le manchon de chambre 1, en partie médiane et dans une
tranche transversale perpendiculaire à l'axe 16, présente, dans le
prolongement axial d'un renflement du manchon de chambre dont il sera
question ci-après, une portion de nervure intérieure 22 coopérant avec le
joint 21 en position de fermeture. For this purpose, the chamber sleeve 1, in the middle part and in a
cross section perpendicular to the
C'est la partie antérieure 10 du manchon de chambre qui va maintenant être
plus précisément décrite. Elle comporte ici, en bordure de manchon et
diamétralement opposés dans le plan axial de la coupe de la figure 2, deux
ensembles d'appui, de poussée et de liaison 23, 24. Chaque ensemble est
logé dans un renflement externe 25 de la paroi 26, à fond plat 27, s'étendant
depuis le bord 28 du manchon sur une relativement petite largeur axiale. A
l'intérieur de chaque renflement, et de même largeur axiale, est disposé un
berceau 29 constitué de deux patins d'appui 30, 31 symétriques par rapport
au plan axial défini ci-dessus, épousant le renflement et, chacun, une petite
portion de la paroi intérieure 32 du manchon. Une goupille de liaison 33
traverse chaque renflement et ses deux patins 30, 31 perpendiculairement
au même plan axial. Enfin, une oreille d'appui radiale 34 s'étend entre les
deux patins d'appui de chaque berceau 29, à la manière d'un fond interne, à
l'opposé du bord antérieur 28 du manchon. Les ressorts 13 de rappel de la
chambre en position d'ouverture, en appui contre les faces radiales d'appui
12 du cylindre 2, sont également respectivement en appui contre les oreilles
d'appui 34 du manchon de chambre 1. Quant au bec de liaison 9 de chaque
bras 7, 8, il est passé, par sa partie d'extrémité libre 35, tournée vers l'axe
16, à l'arrière de la goupille de liaison associée 33. Ainsi, la partie
d'extrémité 35 d'un bec de liaison 9 d'un bras de cage 7, 8 peut, ici,
relativement au manchon de chambre 1, être entraínée en coulissement
relatif sur une course de jeu de longueur égale à la distance séparant
l'oreille d'appui 34 et la goupille de liaison 33 du berceau 29 associé, ce qui
permet de qualifier la liaison en coulissement de la cage et du manchon de
liaison avec jeu. Ce degré de liberté évite ici la propagation des contraintes.This is the
Dans une autre forme de réalisation dont il va être question ci-après, la cage et le manchon pourraient être liés en coulissement sans jeu.In another embodiment which will be discussed below, the cage and sleeve could be slid-free without play.
Le fonctionnement de l'appareil va maintenant être décrit.The operation of the apparatus will now be described.
Lors de la mise en appui de l'appareil contre un matériau récepteur, la cage
6, par l'intermédiaire du palpeur 5, est poussée vers l'arrière de l'appareil.
Les becs de liaison 9 commencent par reculer depuis la goupille de liaison
33 jusqu'à l'oreille d'appui 34 de leur ensemble d'appui, de poussée et de
liaison associé, avant que la cage 4, 6, par les oreilles d'appui 34 servant
d'organe de poussée, ne repousse le manchon de chambre le long du
cylindre 2, en comprimant les ressorts de rappel 13 (figure 2), jusqu'à ce
que les patins d'appui 30, 31 viennent en butée contre les oreilles d'appui 11
du cylindre 2 (figure 3) et que, ainsi, la chambre de combustion 15 soit
fermée, avec étanchéité avant assurée.When the device bears against a receiving material, the cage
6, via the
L'appareil est alors prêt au tir.The device is then ready for shooting.
Quand on dégage l'appareil du matériau récepteur, la détente des ressorts
13 fait coulisser le manchon de chambre 1 vers l'avant sur le cylindre 2,
jusqu'à ce que les portions de nervure intérieure 22 du manchon viennent
en butée contre des amortisseurs 36 en appui contre les joues d'appui 12 du
cylindre et que l'appareil se retrouve en position de chambre de combustion
ouverte. Lors du coulissement d'ouverture du manchon de chambre 1, les
oreilles de poussée 34 entraínent également en coulissement vers l'avant les
becs de liaison 9 et donc les bras 7, 8 de la cage 6. Sous l'action de son
poids, la cage peut éventuellement poursuivre sa course vers l'avant jusqu'à
ce que les bras de liaison 9 viennent en butée contre les goupilles 33.When the device is released from the receiving material, the
Avantageusement, les patins d'appui 30, 31 sont réalisés dans un matériau
amortisseur pour mieux amortir les chocs. Alternativement, ces patins 30,
31 comportent au moins une tranche d'appui arrière transversale 39
destinée à venir en butée contre une oreille d'appui 11 qui, elle, est dans un
matériau amortisseur, tranche rapportée sur le patin, notamment par
collage, soudage.Advantageously, the
On vient de décrire un manchon de chambre à deux ensembles d'appui, de poussée et de liaison, avec jeu chacun comportant un berceau à deux patins.We have just described a chamber sleeve with two sets of support, push and link, with each game having a cradle with two pads.
Dans une variante de réalisation de l'appareil de l'invention, représentée sur
les figures 5, 6 sur lesquelles les mêmes références désignent les mêmes
éléments que sur les autres figures, chaque ensemble est remplacé par un
unique patin d'appui, de poussée et de liaison 43, 44 conformé de façon
particulière.In an alternative embodiment of the apparatus of the invention, shown in
FIGS. 5, 6 on which the same references designate the same
elements than in the other figures, each set is replaced by a
single support pad, thrust and
Tout d'abord, sa forme est telle qu'il puisse être également logé dans un des
renflements externes 25, comme les berceaux 29. En outre, il comporte un
coude de liaison 45 et un doigt de poussée et d'appui 46 prolongeant le
coude de liaison 45. Le coude de liaison 45, en forme d'arceau, reçoit, dans
sa gorge interne concave, une goupille de liaison 33 qui traverse le
renflement associé 25. Le coude de liaison 45 et le doigt de poussée et
d'appui 46 sont liés l'un à l'autre par un pont en ménageant entre eux une
gorge 47 de réception du bec de liaison 9 du bras de cage associé 7, 8. First of all, its shape is such that it can also be housed in one of the
Quant au doigt de poussée et d'appui 46, il s'étend sous une forme
cylindrique depuis une base 48, de plus grande section que le doigt 46, en
ménageant un épaulement annulaire 49 de butée du ressort 13 d'ouverture
de la chambre en butée à son autre extrémité contre la joue d'appui 12 du
cylindre 2.As for the push and
La forme de réalisation des figures 5, 6 se distingue donc essentiellement de celle des autres figures par les caractéristiques suivantes :
- la
cage 4 et le manchon 1 sont liés en coulissement sans jeu ; - les oreilles d'appui 11 ont été supprimées ;
- les

- the
cage 4 and the sleeve 1 are slidably connected without play; - the supporting ears 11 have been removed;
- the
43, 44 are simpler than thepads cradles 29.
Le fonctionnement de l'appareil des figures 5, 6 est le même que celui des autres figures.The operation of the apparatus of FIGS. 5, 6 is the same as that of other figures.
Lors de la mise en appui de l'appareil contre un matériau récepteur, la cage
4, par l'intermédiaire du palpeur, est poussée vers l'arrière de l'appareil. La
cage 4, par les becs 9 et doigts 46 des patins, servant d'organe de poussée,
repousse le manchon de chambre 1 le long du cylindre 2, en comprimant
les ressorts de rappel 13 (figure 5), jusqu'à ce que les doigts 46 des patins
d'appui 42, 44 viennent en butée contre les joues d'appui 12 du cylindre 2
(figure 6) et que, ainsi, la chambre de combustion 15 soit fermée, avec
étanchéité avant assurée.When the device bears against a receiving material, the
L'appareil est alors prêt au tir.The device is then ready for shooting.
Quand on dégage l'appareil du matériau récepteur, la détente des ressorts
13 fait coulisser le manchon de chambre 1 vers l'avant sur le cylindre 2,
jusqu'à ce que les portions de nervure intérieure 22 du manchon viennent
en butée contre des amortisseurs 36 en appui contre les joues d'appui 12 du
cylindre et que l'appareil se retrouve en position de chambre de combustion
ouverte. Lors du coulissement d'ouverture du manchon de chambre 1, les
doigts de poussée 46 entraínent également en coulissement vers l'avant les
becs de liaison 9 et donc les bras 7, 8 de la cage 4.When the device is released from the receiving material, the
Les patins 43, 44, avec leur coude de liaison 45 et leur doigt de poussée et
d'appui 46, sont avantageusement réalisés dans un matériau amortisseur, de
préférence en élastomère, pour mieux amortir les chocs. Tout comme les
patins 30, 31, les patins 43, 44 peuvent comporter au moins une tranche
d'appui arrière transversale 50 en matériau amortisseur.The
