Description

L'invention concerne une crémone, serrure ou crémone-serrure pour fenêtre, porte, porte-fenêtre ou analogue, à rappels alternés de la poignée en position de repos.The invention relates to a cremone bolt, lock or cremone bolt for window, door, French window or the like, with alternating recalls of the handle in the rest position.

On connaît déjà, par le brevet français n° 1.564.650, un mécanisme de crémone provoquant la translation d'une ou de deux tringles, qui soit agencé de telle façon que la poignée revienne automatiquement, sous l'action d'un ressort de rappel, en position de repos horizontal lorsqu'on la lâche, après l'avoir tournée vers le bas pour l'ouverture ou vers le haut pour la fermeture, le mouvement de retour automatique de la poignée de manoeuvre se faisant sans déplacement vertical des tringles. Ce mécanisme comporte un fouillot présentant sur chaque face latérale un ergot faisant saillie et coopérant avec un ressort à spires jointives montées sur un axe et se terminant en deux branches disposées en forme d'épingle. Lorsque l'un des ergots écarte l'une des branches du ressort de rappel, l'autre branche est au repos et maintenue par une butée.We already know, from French Patent No. 1,564,650, a cremone mechanism causing the translation of one or two rods, which is arranged so that the handle returns automatically, under the action of a spring. reminder, in the horizontal rest position when it is released, after having turned it downwards for opening or upwards for closing, the automatic return movement of the operating handle being done without vertical displacement of the rods . This mechanism comprises a follower having on each lateral face a lug projecting and cooperating with a spring with contiguous turns mounted on an axis and ending in two branches arranged in the form of a pin. When one of the lugs spreads one of the branches of the return spring, the other branch is at rest and held by a stop.

Toutefois, la longévité de ce ressort est assez restreinte, ce qui représente un inconvénient certain. En effet, le ressort mis en oeuvre est soumis à une contrainte de torsion alternée importante au niveau des spires extrêmes directement attaquées par chaque branche. La torsion alternée, exercée sur des spires de rayon faible, conduit à une rupture fréquente du ressort.However, the longevity of this spring is quite limited, which represents a certain drawback. Indeed, the spring used is subjected to a significant alternating torsional stress at the level of the extreme turns directly attacked by each branch. The alternating torsion, exerted on turns of small radius, leads to a frequent rupture of the spring.

On connaît également, par le brevet français n° 78.16971 (publié sous le n° 2.427.450), un mécanisme pour crémone comportant un fouillot relié à une poignée dont l'actionnement vers le bas entraîne le déverrouillage de la porte, tandis que son actionnement vers le haut entraîne le verrouillage de la porte. Le fouillot est monté avec jeu et avec le moins de frottement latéral possible, afin que le seul poids de la poignée assure le retour en position de repos du fouillot et de la poignée après son actionnement vers le haut. Une telle disposition permet, en effet, le rappel de la poignée en position de repos horizontal sans l'intervention d'un ressort mis sous tension lors du relèvement de la poignée.Also known, from French patent n ° 78.16971 (published under n ° 2.427.450), a mechanism for cremone bolt comprising a nut connected to a handle whose actuation downwards causes the unlocking of the door, while its pressing up causes the door to lock. The follower is mounted with play and with the least lateral friction possible, so that the only weight of the handle ensures the return of the follower and the handle to the rest position after its actuation upwards. Such an arrangement allows, in fact, the return of the handle to the horizontal rest position without the intervention of a spring energized during relè handle.

Toutefois, le retour en position de repos de la poignée lorsque l'on actionne la poignée vers le haut est des plus aléatoires. En effet, il suffit qu'il y ait un frottement quelconque des différentes pièces mobiles et/ou qu'un corps étranger tel qu'une poussière ait pénétré dans la crémone pour que la poignée reste en position haute et ne retombe pas, sous l'effet de son seul poids, en position de repos.However, the return to the rest position of the handle when the handle is actuated upwards is most uncertain. Indeed, it suffices that there is any friction of the various moving parts and / or that a foreign body such as dust has entered the cremone bolt so that the handle remains in the high position and does not fall under the effect of its own weight, in the rest position.

De même, on connaît, par le brevet français n° 76.36156 (publié sous le n° 2.372.300) un mécanisme comportant un fouillot d'actionnement d'au moins deux tringles à déplacements conjugués opposés et un moyen de rappel associé à un ressort hélicoïdal pour ramener ledit fouillot dans une position stable de repos, quel que soit le sens de manoeuvre qui lui est imprimé.Similarly, we know, from French patent n ° 76.36156 (published under n ° 2.372.300) a mechanism comprising an actuating nut of at least two rods with opposite conjugate displacements and a return means associated with a spring helical to return said follower to a stable position of rest, whatever the direction of operation which is printed thereon.

Ce moyen de rappel est constitué d'un grand nombre de pièces servant à transformer la rotation du fouillot dans une compression du ressort hélicoïdal quel que soit l'actionnement de la poignée, c'est-à-dire que la poignée soit actionnée vers le bas pour l'ouverture ou vers le haut pour la fermeture.This return means consists of a large number of parts used to transform the rotation of the follower in a compression of the helical spring whatever the actuation of the handle, that is to say that the handle is actuated towards the down for opening or up for closing.

Toutefois, ce mécanisme présente plusieurs inconvénients. Du fait que le moyen de rappel doit être placé sur l'alignement passant par le centre du fouillot et que les dimensions du boîtier renfermant le mécanisme doivent rester dans la limite des dimensions habituelles des boîtiers de crémone, serrure ou crémone-serrure, on ne peut prévoir qu'un ressort très court dont l'élasticité est toujours soumise à un effort maximum. Il en résulte une détérioration rapide de cet élément élastique. Si les limites des dimensions habituelles des boîtiers de crémone, serrure ou crémone-serrure ne sont pas respectées, il est nécessaire de modifier les sections habituelles des profils constituant les ouvrants de fenêtre, porte ou porte-fenêtre.However, this mechanism has several drawbacks. Due to the fact that the return means must be placed on the alignment passing through the center of the follower and that the dimensions of the housing containing the mechanism must remain within the limit of the usual dimensions of the cremone bolt, lock or cremone lock bolt, can provide that a very short spring whose elasticity is always subjected to a maximum force. This results in rapid deterioration of this elastic element. If the limits of the usual dimensions of the cremone bolt, lock or cremone bolt lock are not respected, it is necessary to modify the usual sections of the profiles constituting the window, door or French window openings.

Finalement, le grand nombre de pièces utilisées pour le rappel automatique de la poignée à une position de repos augmente non seulement le prix de revient de cette crémone mais également les risques d'incidents de fonctionnement.Finally, the large number of parts used for the automatic return of the handle to a rest position not only increases the cost price of this cremone bolt but also the risk of operating incidents.

La présente invention a pour but de remédier à ces inconvénients. L'invention, telle qu'elle est caractérisée dans les revendications, résout le problème consistant à créer une crémone, serrure ou crémone-serrure pour fenêtre, porte, porte-fenêtre ou analogue, à rappels alternés de la poignée en position de repos, comportant un rappel élastique simple,peu encombrant et peu coûteux, présentant une longévité accrue.The present invention aims to remedy these drawbacks. The invention, as characterized in the claims, solves the problem of creating a cremone bolt, lock or cremone bolt-lock for window, door, French window or the like, with alternating recalls of the handle in the rest position, comprising a simple elastic reminder, compact and inexpensive, having an increased longevity.

Les avantages obtenus grâce à cette invention consistent essentiellement en ceci que l'application de ces caractéristiques permet, outre l'élimination des inconvénients que présente l'état de la technique, une augmentation considérable du rapport entre la course d'action et la longueur totale de l'élément élastique, augmentation qui ramène la fatigue de l'élément élastique pratiquement à néant.The advantages obtained thanks to this invention consist essentially in that the application of these characteristics allows, in addition to the elimination of the drawbacks which the state of the art presents, a considerable increase in the ratio between the stroke and the total length. of the elastic element, an increase which reduces the fatigue of the elastic element to practically nothing.

Une réalisation simple et avantageuse de l'invention, pour sa conception compacte qu'elle procure au dispositif de rappel, se caractérise en ce que l'élément élastique est inséré entre l'élément immobile constitué par deux chants de lumières oblongues pratiquées dans le boîtier de la crémone, serrure ou crémone-serrure et deux butées commandées par le fouillot.A simple and advantageous embodiment of the invention, for its compact design which it provides to the return device, is characterized in that the elastic element is inserted between the stationary element constituted by two songs of oblong lights formed in the housing of the lever, lock or lever-lock and two stops controlled by the follower.

Cette réalisation est également indiquée lorsque l'objet de l'invention s'applique à une crémone, serrure ou crémone-serrure dont l'actionnement de la poignée vers le haut ne produit aucune modification de la position de la crémone, serrure ou crémone-serrure, mais se fait uniquement pour permettre l'ouverture d'un occulus ou d'un survitrage. En effet, l'élimination presque totale de la fatigue de l'élément élastique permet dorénavant à une crémone, serrure ou crémone-serrure dont le rappel de la poignée en position de repos horizontal après son actionnement vers le haut se faisait par gravité, de comporter un rappel élastique sans que la longévité de l'élément élastique soit mise en cause.This embodiment is also indicated when the object of the invention applies to a cremone bolt, lock or cremone bolt whose actuation of the handle upwards does not produce any modification of the position of the cremone bolt, lock or cremone bolt. lock, but is only made to allow the opening of an occulus or an over-glazing. Indeed, the almost total elimination of the fatigue of the elastic element henceforth allows a cremone bolt, lock or cremone bolt whose return of the handle to the horizontal rest position after its actuation upwards is done by gravity, include an elastic return without the longevity of the elastic element being called into question.

Un bon appui de toute la surface de l'extrémité de l'élément élastique est obtenu lorsque l'élément élastique est inséré entre deux butées commandées par le fouillot et mobiles dans deux lumières du boîtier et que les butées coopèrent alternativement avec deux chants du boîtier de la crémone, serrure ou crémone-serrure.Good support of the entire surface of the end of the elastic element is obtained when the elastic element is inserted between two stops controlled by the follower and movable in two slots in the housing and the stops cooperate alternately with two edges of the box tier of the cremone bolt, lock or cremone bolt.

Le dispositif, objet de l'invention, peut délimiter les mouvements alternatifs du fouillot et, par conséquent, de la poignée, lorsque la course des butées dans les lumières correspond à l'un des mouvements alternatifs du fouillot.The device, object of the invention, can delimit the reciprocating movements of the follower and, consequently, of the handle, when the travel of the stops in the slots corresponds to one of the reciprocating movements of the follower.

L'avantage de ces dispositions qui économisent les éléments limitant les mouvements du fouillot, est particulièrement sensible lorsque l'une des lumières délimite le mouvement du fouillot dans un sens, et l'autre lumière délimite le mouvement du fouillot dans le sens contraire.The advantage of these provisions which save the elements limiting the movements of the follower is particularly significant when one of the lights delimits the movement of the follower in one direction, and the other light delimits the movement of the follower in the opposite direction.

Une réalisation préférentielle de l'invention se caractérise en ce que les butées sont commandées par un curseur présentant un chant et/ ou un épaulement et transmettant les mouvements alternatifs du fouillot aux butées.A preferred embodiment of the invention is characterized in that the stops are controlled by a cursor having a song and / or a shoulder and transmitting the reciprocating movements of the follower to the stops.

En effet, l'invention obtien-t par ces caractéristiques que l'élément élastique peut être disposé de manière rectiligne et tangentielle ou approximativement tangentielle par rapport au fouillot.Indeed, the invention obtains by these characteristics that the elastic element can be arranged in a straight line and tangential or approximately tangential with respect to the follower.

L'invention est exposée ci-après plus en détail à l'aide des dessins représentant seulement un mode d'exécution.The invention is set out below in more detail with the aid of the drawings showing only one embodiment.

La figure 1 représente, en vue latérale en coupe, une partie du boîtier d'une crémone pourvue du mécanisme selon l'invention en position de repos ; la figure 2 représente, en vue en élévation, cette même partie, la plaque supérieure étant enlevée ; la figure 3 représente, en vue analogue à celle de la figure 1, la partie du boîtier mais dont la poignée étant en position relevée ; la figure 4 représente, en vue en élévation, une vue analogue à celle de la figure 2, la poignée étant en position relevée ; la figure 5 représente une vue analogue à celle de la figure 1, la poignée étant en position rabaissée ; la figure 6 représente une vue en élévation analogue à celle de la figure 2, la poignée étant en position rabaissée.Figure 1 shows, in sectional side view, a part of the housing of a cremone bolt provided with the mechanism according to the invention in the rest position; 2 shows, in elevational view, this same part, the upper plate being removed; Figure 3 shows, in a view similar to that of Figure 1, the part of the housing but whose handle being in the raised position; 4 shows, in elevational view, a view similar to that of Figure 2, the handle being in the raised position; Figure 5 shows a view similar to that of Figure 1, the handle being in the lowered position; 6 shows a view in elevation similar to that of Figure 2, the handle being in the lowered position.

On se réfère aux figures 1 et 2.We refer to Figures 1 and 2.

La crémone, serrure ou crémone-serrure comporte un boîtier composé de deux plaques 1 et 2. Entre ces plaques 1 et 2 sont disposés les différents éléments assurant le fonctionnement correct, soit de la crémone, soit de la serrure, soit de la crémone-serrure à une ou à deux tringles de manoeuvre. Ces différents éléments sont connus et ne sont pas décrits dans la présente invention. En effet, celle-ci se rapporte a un mécanisme 3 ayant pour but le double retour automatique à sa position de repos de la poignée lorsque celle-ci a été relevée ou abaissée, ce double retour s'effectuant sans aucune action sur le pêne de la serrure ou les tringles de manoeuvre de la crémone ou crémone-serrure.The cremone bolt, lock or cremone bolt comprises a housing composed of two plates 1 and 2. Between these plates 1 and 2 are arranged the various elements ensuring the correct operation, either of the cremone bolt, or of the lock, or of the cremone bolt- lock with one or two operating rods. These various elements are known and are not described in the present invention. Indeed, it relates to a mechanism 3 having for goal the automatic double return to its rest position of the handle when the latter has been raised or lowered, this double return being effected without any action on the latch the lock or the rods for operating the cremone bolt or cremone bolt.

Le mécanisme 3 comporte plusieurs organes de commande et, notamment un fouillot 4 pourvu d'un trou carré 5 dans lequel on introduit le carré de manoeuvre de la poignée. Ce fouillot 4, en plus des doigts de commande nécessaires au fonctionnement de la crémone, de la serrure ou de la crémone-serrure, comporte, sur son pourtour 6, un segment denté 7 coopérant avec un curseur-composé, d'une part, d'une crémaillère 17 dont les dents 13, 14, 15, 16 s'engrènent avec les dents 8, 9, 10, 11, 12 du segment denté 7 et, d'autre part, d'un axe 18. La crémaillère 17 coulisse sur l'axe 18 pouvant lui-même se déplacer verticalement. Sur cet axe 18 sont enfilées une butée supérieure 19 et une butée inférieure 20. Selon le sens de rotation impliquée au. fouillot 4, soit la butée supérieure 19, soit la butée inférieure 20 demeure dans sa position de repos et sert d'appui à l'élément élastique en s'appuyant elle-même sur un élément immobile de la crémone, alors que l'autre butée coopérant avec le fouillot 4, assure la mise sous tension de l'élément élastique dont la force libérée provoque le retour automatique de la poignée en position de repos. La butée supérieure 19 comporte au droit de passage de l'axe 18 un trou 21 de diamètre plus grand que le diamètre de l'axe 18, ce qui permet un déplacement facile des pièces 18 et 19 entre elles. La butée inférieure 20 présente un trou 22 de diamètre inférieur à celui du trou 21. En effet, l'axe 18 comporte à l'emplacement de la butée inférieure 20 un décrochement 23 de sorte que l'épaulement 24 repose sur le pourtour 25 de ladite butée inférieure 20.The mechanism 3 comprises several control members and, in particular a follower 4 provided with a square hole 5 into which the square for operating the handle is introduced. This follower 4, in addition to the control fingers necessary for the operation of the lever, the lock or the lever-lock, comprises, on its periphery 6, a toothed segment 7 cooperating with a cursor-compound, on the one hand, of a rack 17 whose teeth 13, 14, 15, 16 mesh with the teeth 8, 9, 10, 11, 12 of the toothed segment 7 and, on the other hand, of an axis 18. The rack 17 slides on the axis 18 which can itself move vertically. On this axis 18 are threaded an upper stop 19 and a lower stop 20. According to the direction of rotation involved. follower 4, either the upper stop 19 or the lower stop 20 remains in its rest position and serves as a support for the elastic element, itself leaning on a stationary element of the cremone bolt, while the other stop cooperating with the follower 4, ensures the tensioning of the elastic element whose released force causes the automatic return of the handle to the rest position. The upper stop 19 has at the right of passage of the axis 18 a hole 21 of diameter larger than the diameter of the axis 18, which allows easy movement of the parts 18 and 19 between them. The lower stop 20 has a hole 22 of diameter smaller than that of the hole 21. In fact, the axis 18 comprises at the location of the lower stop 20 a recess 23 so that the shoulder 24 rests on the periphery 25 of said lower stop 20.

La butée supérieure 19 comporte à chaque extrémité un tourillon 26, 27 coulissant dans des lumières oblongues 28, 29 réalisées dans les plaques 1 et 2 du boîtier. De même, la butée inférieure 20 présente à chaque extrémité un tourillon 30, 31 coulissant dans des lumières oblongues 32, 33 pratiquées dans les plaques 1 et 2. La longueur de ces lumières oblongues 28, 29 et 32, 33 correspond à la longueur de la course des deux butées 19 et 20.The upper stop 19 has at each end a pin 26, 27 sliding in oblong slots 28, 29 produced in the plates 1 and 2 of the housing. Similarly, the lower stop 20 has at each end a pin 30, 31 sliding in oblong slots 32, 33 made in the plates 1 and 2. The length of these oblong slots 28, 29 and 32, 33 corresponds to the length of the travel of the two stops 19 and 20.

La crémaillère 17 comporte, à son extrémité inférieure 34, un chant curviligne 35 pour augmenter le plan d'action entre ladite crémaillère 17 et le pourtour 36 de la butée supérieure 19.The rack 17 has, at its lower end 34, a curvilinear edge 35 to increase the plane of action between said rack 17 and the periphery 36 of the upper stop 19.

L'axe 18 est pourvu à chaque extrémité 37, 38 d'une tête 39, 40. La tête supérieure 39 repose sur le chant supérieur 41 de la crémaillère 17 et la tête inférieure 40 prend appui contre le pourtour 25 de la butée inférieure 20.The axis 18 is provided at each end 37, 38 with a head 39, 40. The upper head 39 rests on the upper edge 41 of the rack 17 and the lower head 40 bears against the periphery 25 of the lower stop 20 .

On dispose entre les deux butées 19 et 20 un élément élastique 42 tel qu'un ressort hélicoïdal. Celui-ci, en phase de repos, est de préférence en position précontrainte. De ce fait, le ressort 42 exerce une poussée sur les deux butées 19 et 20 de sorte que les tourillons 26, 27 de la butée supérieure 19 prennent appui contre le chant supérieur 43, 44 des lumières oblongues 28, 29 et que les tourillons 30, 31 de la butée inférieure 20 prennent appui contre le chant inférieur 45, 46 des lumières oblongues 32, 33. Les chants 43, 44, 45, 46 des lumières oblongues 32, 33 constituent l'élément immobile de la crémone coopérant par l'intermédiaire des deux butées 19, 20 avec l'élément élastique 42. Le ressort 42 a une longueur relativement importante. De ce fait, la fatigue impliquée à cet élément élastique se répartit sur un relativement grand nombre de spires et on augmente considérablement le rendement et ainsi la longévité dudit ressort 42 et, par voie de conséquence, la longévité du mécanisme 3.There is between the two stops 19 and 20 an elastic element 42 such as a helical spring. The latter, in the rest phase, is preferably in the prestressed position. Therefore, the spring 42 exerts a thrust on the two stops 19 and 20 so that the pins 26, 27 of the upper stop 19 bear against the upper edge 43, 44 of the oblong slots 28, 29 and that the pins 30 , 31 of the lower stop 20 bear against the lower edge 45, 46 of the oblong slots 32, 33. The edges 43, 44, 45, 46 of the oblong slots 32, 33 constitute the stationary element of the cremone bolt cooperating with the intermediate of the two stops 19, 20 with the elastic element 42. The spring 42 has a relatively large length. As a result, the fatigue involved in this elastic element is distributed over a relatively large number of turns and the efficiency and thus the longevity of said spring 42 is considerably increased and, consequently, the longevity of mechanism 3.

La poignée au repos occupe la position représentée par son axe 47. Par ailleurs, l'axe longitudinal 48 de l'axe 18 est déplacé par rapport au plan médian vertical du boîtier. De ce fait, on obtient un espace vide 49 permettant la mise en place d'un certain nombre de pièces nécessaires au fonctionnement de la crémone, serrure ou crémone-serrure.The handle at rest occupies the position represented by its axis 47. Furthermore, the longitudinal axis 48 of the axis 18 is moved relative to the vertical median plane of the housing. As a result, an empty space 49 is obtained allowing the installation of a certain number of parts necessary for the operation of the cremone bolt, lock or cremone bolt.

On se réfère aux figures 3 et 4.We refer to Figures 3 and 4.

On relève la poignée. De ce fait, on implique au fouillot 4 une rotation selon la flèche F1. Les dents 8 à 12 s'engrènent avec les dents 13 à 16 de la crémaillère 17 et celle-ci se déplace vers le haut. Le chant supérieur 41 de la crémaillère 17 coopère avec la tête 39 de l'axe 18 et exerce une traction sur ledit axe 18. Ce dernier coulisse à travers le trou 21 de la butée supérieure 19. Cette traction est transmise par la tête 40 à la butée inférieure 20 qui se déplace vers le haut jusqu'à ce que les tourillons 30, 31 de cette butée inférieure 20 prennent appui contre les chants supérieurs 50, 51 des lumières oblongues 32, 33. Par contre, la butée supérieure 19 ne peut se déplacer vers le haut du fait que ses tourillons 26, 27 prennent appui contre les chants supérieurs 43, 44 des lumières oblongues 28, 29. De ce fait, le ressort 42 est comprimé. En relâchant la poignée, le ressort 42 se détend et exerce une poussée sur la butée inférieure 20. Celle-ci exerce, par l'intermédiaire de la tête 40, une traction sur l'axe 18, traction transmise par l'intermédiaire de la tête 39 à la crémaillère 17. Ladite crémaillère'17 provoque la rotation en sens contraire du fouillot 4 et la poignée revient à la position de repos indiquée dans la figure 2.We raise the handle. Therefore, the follower 4 involves rotation according to the arrow F 1 . The teeth 8 to 12 mesh with the teeth 13 to 16 of the rack 17 and the latter moves upwards. The upper edge 41 of the rack 17 cooperates with the head 39 of the axis 18 and exerts traction on said axis 18. The latter slides through the hole 21 of the upper stop 19. This traction is transmitted by the head 40 to the lower stop 20 which moves upwards until the pins 30, 31 of this lower stop 20 bear against the upper edges 50, 51 of the oblong slots 32, 33. On the other hand, the upper stop 19 cannot move upwards because its pins 26, 27 bear against the upper edges 43, 44 of the oblong slots 28, 29. As a result, the spring 42 is compressed. By releasing the handle, the spring 42 relaxes and exerts a thrust on the lower stop 20. The latter exerts, by means of the head 40, a traction on the axis 18, traction transmitted by means of the head 39 at the rack 17. Said rack causes the follower 4 to rotate in the opposite direction and the handle returns to the rest position indicated in FIG. 2.

On se réfère aux figures 5 et 6.We refer to Figures 5 and 6.

On rabaisse la poignée. De ce fait, le fouillot 4 pivote selon la flèche F2* Les dents 8 à 12 s'engrènent avec les dents 13 à 16 de la crémaillère 17 et cette dernière est poussée vers le bas. La poussée est transmise par son chant curviligne 35 à la butée supérieure 19 jusqu'à ce que les tourillons 26, 27 prennent appui contre les chants inférieurs 52, 53 des lumières oblongues 28, 29. La crémaillère 17 et la butée supérieure 19 coulissent le long de l'axe 18, ce dernier ne pouvant se déplacer vers le bas du fait que l'épaulement 24 prend appui sur la butée inférieure 20 dont les tourillons 30, 31 prennent appui sur les chants inférieurs 45, 46 des lumières oblongues 32, 33. Ainsi, on comprime à nouveau le ressort 42. Toutefois, cette compression est de haut en bas et donc contraire à la compression dirigée de bas vers le haut lorsque l'on soulève la poignée.We lower the handle. Therefore, the follower 4 pivots according to the arrow F 2 * The teeth 8 to 12 mesh with the teeth 13 to 16 of the rack 17 and the latter is pushed down. The thrust is transmitted by its curvilinear edge 35 to the upper stop 19 until the pins 26, 27 bear against the lower edges 52, 53 of the oblong slots 28, 29. The rack 17 and the upper stop 19 slide the along the axis 18, the latter being unable to move downwards because the shoulder 24 bears on the lower stop 20 whose pins 30, 31 bear on the lower edges 45, 46 of the oblong slots 32, 33. Thus, the spring 42 is again compressed. However, this compression is from top to bottom and therefore contrary to the compression directed from the bottom up when the handle is raised.

En relâchant la poignée, le ressort 42 se détend et il exerce une poussée sur la butée supérieure 19 qui transmet cette poussée à la crémaillère 17. Cette dernière provoque.la rotation en sens contraire du fouillot 4 et la poignée revient à la position de repos indiquée dans la figure 2.By releasing the handle, the spring 42 relaxes and it exerts a thrust on the upper stop 19 which transmits this thrust to the rack 17. The latter causes the rotation of the follower 4 in the opposite direction and the handle returns to the rest position shown in figure 2.
