Description

Le domaine de l'invention de la présente demande est celui de la fixation d'éléments du type clous ou agrafes à l'aide d'un outil à actionnement à main, mais dans un matériau support éloigné de l'opérateur et inaccessible à son outil, même tenu à bout de bras.The field of invention of the present application is that of fixing of nails or staples like elements using a tool actuated by hand, but in a support material distant from the operator and inaccessible to his tool, even when held at arm's length.

Le matériau support qu'on évoque ici est par exemple celui d'un plafond.The support material which we evoke here is for example that of a ceiling.

L'outil à actionnement à main qu'on évoque également ici est du genre appareil d'entraínement d'éléments de fixation à tir indirect, avec un piston propulsé vers l'avant sous l'action de la combustion d'une charge de poudre ou de l'explosion d'un mélange de gaz inflammable, pour entraíner un élément de fixation.The hand-operated tool also discussed here is of the type device for driving indirect fire fasteners, with a piston propelled forward under the action of the combustion of a charge of powder or explosion of a flammable gas mixture, to drive a fastener.

L'invention vise à éviter à l'opérateur d'avoir à monter sur une chaise, un escabeau ou autre échelle, pour pouvoir actionner son outil dans de bonnes conditions de stabilité et d'attitude.The invention aims to avoid the operator from having to get on a chair, a stepladder or other ladder, to be able to operate his tool in good conditions of stability and attitude.

Par actionnement, dans le cas d'un appareil à tir indirect, il faut entendre l'actionnement de la détente de l'appareil.By actuation, in the case of an indirect fire device, it is necessary hear actuation of the trigger on the device.

Ainsi l'invention concerne une perche de télé actionnement d'un outil à main comportant, à une extrémité, des moyens de fixation de l'outil, une tringlerie d'actionnement de l'outil, un manchon d'actionnement de l'outil, agencé pour coulisser le long de la perche, et des moyens pour solidariser le manchon d'actionnement à la tringlerie.Thus, the invention relates to a remote actuation pole of a tool hand comprising, at one end, means for fixing the tool, a tool actuation linkage, an actuation sleeve the tool, arranged to slide along the pole, and means for secure the actuating sleeve to the linkage.

Dans la forme de réalisation préférée de la perche de l'invention, la perche comporte au moins un élément tubulaire dans lequel s'étend la tringlerie et le manchon d'actionnement comporte une clavette de solidarisation qui s'étend à travers une fenêtre ménagée dans l'élément tubulaire et à travers laquelle s'étend la tringlerie.In the preferred embodiment of the pole of the invention, the pole comprises at least one tubular element in which the linkage and the actuation sleeve includes a key joining which extends through a window in the element tubular and through which the linkage extends.

De préférence encore, la clavette de solidarisation est montée pivotante sur le manchon d'actionnement sous l'action de moyens de rappel de cette clavette en position de coincement sur la tringlerie.More preferably, the securing key is pivotally mounted on the actuating sleeve under the action of return means of this key in the wedging position on the linkage.

De préférence toujours, la perche de l'invention est télescopique et comporte au moins deux éléments tubulaires emmanchés l'un dans l'autre, les moyens de fixation de l'outil étant prévus sur l'élément tubulaire intérieur et le manchon d'actionnement, sur l'élément tubulaire extérieurStill preferably, the pole of the invention is telescopic and comprises at least two tubular elements fitted one in the other, the means for fixing the tool being provided on the element inner tube and the actuating sleeve, on the element tubular exterior

Dans ce cas, il peut être prévu des manchons de verrouillage de la position relative des deux éléments tubulaires.In this case, it is possible to provide locking sleeves for the relative position of the two tubular elements.

Alors, il peut être intéressant qu'un premier manchon de verrouillage soit fixé sur l'élément tubulaire extérieur à une extrémité et s'étende le long de l'élément tubulaire intérieur à l'autre extrémité , qui est agencée pour, par vissage et effet de coin avec un deuxième manchon disposé autour de l'élément tubulaire intérieur, être serrée contre l'élément tubulaire intérieur et solidariser ainsi les deux éléments tubulaires en position.So, it may be interesting that a first locking sleeve is fixed on the outer tubular element at one end and extends the along the inner tubular member at the other end, which is arranged for, by screwing and wedge effect with a second sleeve arranged around the inner tubular element, be clamped against the inner tubular element and thus securing the two elements tubular in position.

Avantageusement encore, l'extrémité de fixation de la perche d'actionnement est tubulaire, un fourreau de réception de la tringlerie est emmanché par une extrémité dans l'extrémité tubulaire de la perche et un manchon de fixation de l'outil est emmanché sur l'extrémité tubulaire de la perche, l'extrémité tubulaire de la perche, le fourreau et le manchon de fixation étant solidaires en rotation.Advantageously also, the attachment end of the pole actuator is tubular, a sleeve for receiving the linkage is fitted by one end into the tubular end of the pole and a tool fixing sleeve is fitted on the end tubular of the pole, the tubular end of the pole, the sheath and the fixing sleeve being integral in rotation.

Avantageusement, l'autre extrémité du fourreau est agencée pour coopérer avec un moyeu solidaire de tirants d'écartement de l'outil pour, par un étrier de retenue, créer un effet antagoniste sur ledit outil et ainsi immobiliser l'outil.Advantageously, the other end of the sheath is arranged to cooperate with a hub integral with tool spacers to, by a retaining clip, create an antagonistic effect on said tool and thus immobilizing the tool.

L'invention sera mieux comprise à l'aide de la description suivante d'une forme de réalisation préférée de la perche de télé actionnement selon l'invention en référence au dessin annexé sur lequel :

  • la figure 1 représente une vue perspective de l'ensemble de la perche de télé actionnement seule ;
  • la figure 2A est une vue en coupe longitudinale du manchon d'actionnement de l'outil en position de repos;

  • la figure 7 est une vue perspective de cette même extrémité et de l'outil y fixé, en position d'actionnement.
The invention will be better understood with the aid of the following description of a preferred embodiment of the remote actuating pole according to the invention with reference to the appended drawing in which:
  • FIG. 1 represents a perspective view of the whole of the remote actuation pole only;
  • FIG. 2A is a view in longitudinal section of the actuating sleeve of the tool in the rest position;
  • FIG. 2B is a view in longitudinal section of the actuating sleeve during actuation of the tool;

  • Figure 6 is a side view of the fixing end of the actuating pole and the tool attached thereto, the linkage being in the rest position; and
  • Figure 7 is a perspective view of the same end and the tool attached thereto, in the actuating position.

En référence à la figure 1, la perche de télé actionnement comporte un élément tubulaire 40 cylindrique creux, une tringlerie 11 s'étendant à l'intérieur de l'élément tubulaire 40 et, en l'extrémité 10 de la perche 1, des moyens de fixation de l'outil 100 à télé - actionner (figures 6 et 7). Un manchon 12 d'actionnement, rendu solidaire de la tringlerie 11 quand on télé - actionne l'outil, coulisse sur ledit élément tubulaire 40 et permet, par l'extrémité 111 de la tringlerie 11, d'actionner la détente 101 de l'outil 100.Referring to Figure 1, the remote actuation pole includes a tubular element 40 hollow cylindrical, a linkage 11 extending to the inside of the tubular element 40 and, at the end 10 of the pole 1, means for fixing the tool 100 to be remotely actuated (Figures 6 and 7). An actuating sleeve 12, made integral with the linkage 11 when the tool is tele-operated, slides on said tubular element 40 and allows, by the end 111 of the linkage 11, to actuate the trigger 101 of tool 100.

Les moyens de fixation de l'outil sont composés d'un étrier en deux parties 21 et 25, s'appuyant sur un manchon 20 de fixation solidaire de l'extrémité 10 de la perche, munies chacune de deux griffes 22, 23 et 26, 27 agencées pour retenir l'outil sous l'action antagoniste d'une poussée l'écartant de l'extrémité 10, exercée par des tirants d'écartement 36, 37, 38, 39 montés sur un moyeu 30, comme expliqué plus loin.The means of fixing the tool is composed of a bracket in two parts 21 and 25, supported by a sleeve 20 for fastening integral with the end 10 of the pole, each provided with two claws 22, 23 and 26, 27 arranged to retain the tool under the antagonistic action of a thrust pushing it away from the end 10, exerted by tie rods spacers 36, 37, 38, 39 mounted on a hub 30, as explained further.

Le manchon d'actionnement 12, en référence aux figures 2A, 2B, 3, comporte une clavette 13 de solidarisation pour le solidariser à la tringlerie 11. Ladite clavette, de forme globalement parallélépipédique, est montée pour pivoter autour d'un axe 19 prévu dans le manchon 12. A cet effet, la clavette s'étend à travers deux fenêtres 41, 42 ménagées dans l'élément tubulaire 40, sensiblement symétriques par rapport à l'axe du manchon 12, d'une longueur sensiblement égale à la course du manchon 12 sur le tube 40. La clavette est percée d'un orifice 18, ici cylindrique, permettant le passage avec jeu de la tringlerie 11. Le jeu permet à la clavette de pivoter, mais d'un angle 180 limité par ses bords opposés 181 les plus éloignés. Du fait que la clavette s'étend dans deux fenêtres opposées de l'élément tubulaire 40, tout arc-boutement gênant est évité lors du réglage de la longueur de la perche.The actuating sleeve 12, with reference to FIGS. 2A, 2B, 3, includes a key 13 for securing it to the linkage 11. Said key, of generally parallelepiped shape, is mounted to pivot about an axis 19 provided in the sleeve 12. To this end, the key extends through two windows 41, 42 formed in the tubular element 40, substantially symmetrical with respect to the axis of the sleeve 12, of a length substantially equal to the stroke of the sleeve 12 on the tube 40. The key is pierced with an orifice 18, here cylindrical, allowing passage with clearance of the linkage 11. The clearance allows the key to pivot, but at an angle 180 limited by its edges opposite farthest 181. Because the key extends in two opposite windows of the tubular element 40, any annoying bracing is avoided when adjusting the length of the pole.

Un piston 14, poussé par un ressort 15 en appui sur une bague 17, est appliqué plus ou moins fortement, ou pas du tout, sur la clavette 13, la bague 17 étant solidaire de l'élément tubulaire 40, ici au moyen d'une goupille 16.A piston 14, pushed by a spring 15 bearing on a ring 17, is applied more or less strongly, or not at all, on the key 13, the ring 17 being integral with the tubular element 40, here by means of a pin 16.

Alors que sur la figure 2A, la clavette 13 n'est pas inclinée de l'angle 180 et que par conséquent la tringlerie est libre de coulisser dans l'orifice 18, sur la figure 2B, le manchon d'actionnement 12 peut être sollicité manuellement vers le bas en compressant le ressort 15, ce qui entraíne que, sous l'action du ressort 15 et du piston 14, la clavette 13 pivote et coince la tringlerie par les bords 181 de son orifice 18, ce qui la solidarise au manchon 12. A l'inverse, le manchon 12 est rappelé vers le haut par un dispositif présenté plus loin.Whereas in FIG. 2A, the key 13 is not inclined by the angle 180 and therefore the linkage is free to slide in the orifice 18, in FIG. 2B, the actuating sleeve 12 can be manually biased downwards by compressing the spring 15, which causes that, under the action of the spring 15 and the piston 14, the key 13 pivots and wedges the linkage by the edges 181 of its orifice 18, which secures it to the sleeve 12. Conversely, the sleeve 12 is recalled upwards by a device presented below.

La perche de télé actionnement est prévue pour être télescopique et comporter un autre élément tubulaire 50, ici intérieur, et coulissant dans l'élément tubulaire extérieur 40, et pouvant y être fixé en fonction de la longueur d'emmanchement souhaitée.The remote actuation pole is designed to be telescopic and include another tubular element 50, here interior, and sliding in the outer tubular element 40, and which can be fixed to it as a function of the desired fitting length.

La bague 17 et le piston 14 laissant un passage libre à la tringlerie 11, prévue de longueur suffisante, la solidarisation de la tringlerie 11 au manchon d'actionnement 12 peut être réalisée en une zone de ladite tringlerie qui correspond à cette longueur d'emmanchement.The ring 17 and the piston 14 leaving a free passage to the linkage 11, provided of sufficient length, the attachment of the linkage 11 to actuating sleeve 12 can be made in an area of said linkage which corresponds to this fitting length.

Pour régler la longueur d'emmanchement souhaitée, en référence à la figure 4, l'élément tubulaire extérieur 40 comporte un manchon 60 de verrouillage, qui lui est solidaire en son extrémité la plus éloignée de l'extrémité 10 de la perche, grâce à une goupille 62, et l'élément tubulaire intérieur 50 comporte un manchon de verrouillage 70, monté coulissant sur l'élément tubulaire 50.To set the desired fitting length, with reference to the Figure 4, the outer tubular member 40 comprises a sleeve 60 of locking, which is integral with it at its end furthest from the end 10 of the pole, by means of a pin 62, and the element inner tubular 50 has a locking sleeve 70, mounted sliding on the tubular element 50.

Les manchons de verrouillage 60 et 70 coopèrent pour solidariser les éléments tubulaires 40 et 50 entre eux en une zone quelconque de l'élément tubulaire 50 de la façon suivante :

  • le manchon de verrouillage 70 comporte un alésage axial taraudé 72 pouvant se visser sur une partie cylindrique externe filetée 63 du manchon de verrouillage 60,
  • le manchon de verrouillage 70 comporte un alésage conique axial 71 en deçà de l'alésage taraudé 72 et le manchon de verrouillage 60 comporte, au-delà de sa partie cylindrique externe filetée 63, une jupe fendue 64 s'étendant le long de l'élément tubulaire intérieur 50 et se terminant par une surface conique agencée pour épouser l'alésage conique 71 du manchon 70, présentant une certaine élasticité, et assurer ainsi un effet de coin,
  • quand on visse le manchon de verrouillage 70 sur le manchon de verrouillage 60 à l'endroit choisi de l'élément tubulaire 50, les languettes de fixation de la jupe 64, entre les fentes, sont serrées sur ledit élément tubulaire par l'alésage conique 71, ce qui, par effet de coin, solidarise l'élément tubulaire interne 50 au manchon de verrouillage 60 donc à l'élément tubulaire externe 40 en position relative par rapport à celui-ci.
The locking sleeves 60 and 70 cooperate to secure the tubular elements 40 and 50 together in any area of the tubular element 50 in the following manner:
  • the locking sleeve 70 has a threaded axial bore 72 which can be screwed onto a threaded external cylindrical part 63 of the locking sleeve 60,
  • the locking sleeve 70 comprises an axial conical bore 71 below the tapped bore 72 and the locking sleeve 60 comprises, beyond its external cylindrical threaded portion 63, a split skirt 64 extending along the inner tubular element 50 and ending in a conical surface arranged to match the conical bore 71 of the sleeve 70, having a certain elasticity, and thus ensuring a wedge effect,
  • when the locking sleeve 70 is screwed onto the locking sleeve 60 at the chosen location of the tubular element 50, the tabs for fixing the skirt 64, between the slots, are tightened on said tubular element by the conical bore 71, which, by wedge effect, secures the internal tubular element 50 to the locking sleeve 60 therefore to the external tubular element 40 in relative position relative to the latter.

Autour de l'élément tubulaire 50, on a inséré un ressort 90 de protection entre le manchon de verrouillage 70 et le manchon de fixation 20, de sorte que lors du desserrage des languettes de la jupe 64, lesdits manchons ne viennent pas brutalement en butée l'un contre l'autre et ne risquent pas de blesser l'utilisateur.Around the tubular element 50, a spring 90 of protection between the locking sleeve 70 and the protection sleeve attachment 20, so that when the tabs of the skirt 64 are released, said sleeves do not abruptly abut one against the other the other and do not risk injuring the user.

Les moyens de fixation de l'outil 100 à l'extrémité 10 de la perche 1 vont maintenant être présentés en référence aux figures 5 et 6.The means for fixing the tool 100 to the end 10 of the pole 1 will now be presented with reference to FIGS. 5 and 6.

Le manchon de fixation 20 est fixé à l'extrémité supérieure de l'élément tubulaire interne 50, qui est l'extrémité 10 de la perche, et dans laquelle est emmanchée l'extrémité 81 d'un fourreau 80 de réception de la tringlerie 11. L'extrémité tubulaire de la perche (le tube interne 50), le fourreau 80 et le manchon de fixation 20 sont solidarisés par une goupille 91.The fixing sleeve 20 is fixed to the upper end of the internal tubular element 50, which is the end 10 of the pole, and in which is fitted the end 81 of a sheath 80 of reception of the linkage 11. The tubular end of the pole (the tube internal 50), the sleeve 80 and the fixing sleeve 20 are secured by a pin 91.

L'autre extrémité 82 du fourreau 80 comporte un filetage sur lequel est vissée la bague de blocage 31 d'un moyeu 30, le taraudage de la bague étant « à gauche ». Le moyeu 30 est solidaire de tirants d'écartement, dans l'exemple ici considéré, au nombre de quatre, 36, 37, 38, 39, régulièrement disposés et comportant en leur extrémité libre des doigts 360, 370, 380, 390 cylindriques agencés pour pouvoir être mis en appui sur des surfaces 110 de la structure arrière de l'outil 100. The other end 82 of the sleeve 80 has a thread on which is screwed the locking ring 31 of a hub 30, the thread of the ring being "on the left". The hub 30 is integral with spacers, in the example considered here, four, 36, 37, 38, 39, regularly arranged and having fingers at their free end 360, 370, 380, 390 cylindrical arranged to be able to be supported on surfaces 110 of the rear structure of the tool 100.

En sa partie médiane, le fourreau 80 comporte une collerette 84 agencée pour coopérer avec le manchon 20 de fixation pour maintenir un étrier comportant deux parties, une mâle 25 et une femelle 21, séparables mais agencées pour s'assembler l'une dans l'autre par des semelles mâle 29 et femelle 28 lorsqu'elles s'emboítent entre la collerette 84 et le manchon 20 sur le fourreau 80.In its middle part, the sheath 80 has a flange 84 arranged to cooperate with the fixing sleeve 20 to maintain a stirrup comprising two parts, a male 25 and a female 21, separable but arranged to be assembled one inside the other by male 29 and female 28 soles when they fit between the flange 84 and the sleeve 20 on the sheath 80.

Quand l'outil 100 est en place dans l'étrier, les parties d'étrier 21 et 25 s'étendent au delà de la structure arrière de l'outil 100 jusqu'à une conformation de ladite structure présentant des surfaces 112 en creux à concavité orientée vers l'avant_et sur lesquelles des griffes 22, 23, 26, 27 desdites parties d'étrier 21 et 25 peuvent prendre appui et s'encastrer dans les creux de ces surfaces 112.When the tool 100 is in place in the caliper, the caliper parts 21 and 25 extend beyond the rear structure of the tool 100 to a conformation of said structure having recessed surfaces 112 to concavity oriented forward_and on which claws 22, 23, 26, 27 of said stirrup parts 21 and 25 can bear and become embedded in the hollows of these surfaces 112.

De plus, un doigt 390 du tirant 39 traverse une patte 251 de la partie 25 de l'étrier (voir figures 1 et 5) de sorte que lorsqu'on fait tourner l'étrier autour de la perche, les tirants d'écartement 36, 37, 38, 39 tournent également autour de la perche et entraínent le moyeu 30 dans cette rotation, moyeu qui se visse alors sur le fourreau 80.In addition, a finger 390 of the tie rod 39 crosses a tab 251 of the part 25 bracket (see Figures 1 and 5) so that when the bracket is rotated around the pole, the tie rods 36, 37, 38, 39 rotate also around the pole and drive the hub 30 in this rotation, hub which then screws onto the sleeve 80.

De même, la tringlerie 11 est entraínée dans cette rotation par des pattes 211 et 212 (voir figure 7) solidaires de la partie 21 de l'étrier. Il en résulte qu'en serrant l'outil 100 entre l'étrier et les tirants d'écartement, l'outil, les parties 21 et 25 de l'étrier, les tirants d'écartement 36, 37, 38, 39, le moyeu 30, et la tringlerie 11 restent solidaires en rotation.Similarly, the linkage 11 is driven in this rotation by legs 211 and 212 (see Figure 7) integral with part 21 of the stirrup. It results by tightening the tool 100 between the stirrup and the spacers, the tool, the parts 21 and 25 of the caliper, the tie rods 36, 37, 38, 39, the hub 30, and the linkage 11 remain integral in rotation.

Enfin, la tringlerie 11 comporte un piston 9 coulissant dans l'extrémité 82 du fourreau 80 et soumis à une force de rappel exercée par un ressort 83.Finally, the linkage 11 comprises a piston 9 sliding in the end 82 of the sleeve 80 and subjected to a restoring force exerted by a spring 83.

Pour mettre en place l'outil entre les deux parties 21 et 25 de l'étrier, il faut les écarter l'une de l'autre transversalement à la perche en faisant coulisser leurs semelles mâle 29 et femelle 28 l'une dans l'autre, placer la structure arrière de l'outil entre leurs griffes 22, 23, 26, 27 puis rapprocher ces deux parties dans le mouvement inverse pour mettre leurs griffes en face des surfaces 112.To place the tool between the two parts 21 and 25 of the caliper, it must separate them from each other transversely to the pole by making slide their male 29 and female 28 soles into each other, place the rear structure of the tool between their claws 22, 23, 26, 27 then bring these two parts together in reverse motion to put their claws in front of surfaces 112.

Pour le serrage de l'outil 100 entre les griffes de l'étrier 22, 23, 26, 27 et les doigts 360, 370, 380, 390 des tirants d'écartement 36, 37, 38, 39, on le tourne autour de la perche 1, ou on visse le manchon de fixation 20 de la perche autour de l'ensemble étrier et outil. Ce faisant, cet ensemble étant solidaire en rotation du moyeu 30, ce dernier se visse autour du fourreau 80. Le filetage du fourreau et de la bague 31 étant à gauche, les doigts 360, 370, 380, 390 s'écartent de l'extrémité 10 de la perche, puis écartent, en s'appuyant sur les surfaces 110 de la structure arrière de l'outil 100, l'outil lui-même de la perche, et appliquent les surfaces 112 contre les griffes 22, 23, 26, 27 de l'étrier. Par effet antagoniste dû à l'étrier, les semelles 28, 29 exercent une traction sur la collerette 84 du fourreau 80, ce qui les solidarise au fourreau 80, donc à l'extrémité 10 de la perche 1.For clamping the tool 100 between the claws of the caliper 22, 23, 26, 27 and the fingers 360, 370, 380, 390 of the tie rods 36, 37, 38, 39, we turn it around the pole 1, or we screw the fixing sleeve 20 of the pole around the caliper and tool assembly. In doing so, this assembly being integral in rotation with the hub 30, the latter is screwed around the sleeve 80. The thread of the sleeve and of the ring 31 being at left, fingers 360, 370, 380, 390 move away from end 10 of the pole, then move away, relying on the surfaces 110 of the structure back of tool 100, the tool itself of the pole, and apply the surfaces 112 against the claws 22, 23, 26, 27 of the stirrup. By effect antagonist due to the stirrup, the soles 28, 29 exert a traction on the collar 84 of the sleeve 80, which secures them to the sleeve 80, therefore to the end 10 of the pole 1.

Pour actionner l'outil, on actionne le manchon d'actionnement 12 vers le bas (si l'outil doit être présenté vers le haut), lequel comprime le ressort 15 par l'intermédiaire du piston 14. Le piston 15 repousse et fait pivoter la clavette 13 dans une position de solidarisation (181) de la tringlerie 11. Par suite, la tringlerie est tirée vers le bas, et actionne la détente 101 de l'outil grâce à un bec terminal 111. En même temps, par l'intermédiaire du piston 9, la tringlerie 11 comprime le ressort 83.To activate the tool, the actuating sleeve 12 is actuated the bottom (if the tool is to be presented upwards), which compresses the spring 15 via the piston 14. The piston 15 pushes back and makes pivot the key 13 in a securing position (181) of the linkage 11. As a result, the linkage is pulled down, and activates the trigger 101 of the tool thanks to a terminal spout 111. At the same time, by through the piston 9, the linkage 11 compresses the spring 83.

Après actionnement de l'outil, on relâche le manchon d'actionnement 12, le ressort 83 repousse le piston 9, ce qui a pour effet de tirer la tringlerie 11 vers le haut (toujours dans l'hypothèse d'une action de l'outil vers le haut), d'écarter le bec terminal 111 de la détente 101 et de désolidariser ladite tringlerie du manchon d'actionnement 12, lequel, sous l'action du ressort 15, du piston 14, et de la clavette 13, revient à sa position de repos, c'est-à-dire avant actionnement.After actuation of the tool, the actuation sleeve is released 12, the spring 83 pushes back the piston 9, which has the effect of pulling the linkage 11 upwards (always assuming an action of the tool up), to move the terminal spout 111 away from the trigger 101 and detaching said linkage from the actuating sleeve 12, which, under the action of the spring 15, of the piston 14, and of the key 13, amounts to its rest position, that is to say before actuation.
