Abstract

The key blank has a manually operable rod (51) oriented along a longitudinal axis (X), and a key-bit (52) carried by an end (510) of the rod to activate a lock. The key-bit has a reduced section (50), in a plane (Pt) transversal to the longitudinal axis, partially made by a hollow groove (53). The reduced section is asymmetric with respect to all planes parallel to the axis (X) and makes the axis (X) as axis of symmetry of rotation.

Description

L'invention concerne, de façon générale, le domaine des serrures de sûreté.The invention relates generally to the field of safety locks.

Plus précisément, l'invention, suivant un premier de ses aspects, concerne une serrure de sûreté, comprenant un corps essentiellement cylindrique, allongé suivant un axe longitudinal, un barillet présentant une entrée de clef et monté dans le corps à rotation autour de l'axe longitudinal et à translation le long de l'axe longitudinal suivant une direction d'introduction de la clef, à partir d'une position de repos vers laquelle il est élastiquement sollicité, au moins un premier volet d'occultation de l'entrée de clef, monté mobile dans le corps dans un plan transversal à l'axe longitudinal, et élastiquement rappelé vers une position de repos par une force élastique centripète, et une gorge interne pratiquée dans une périphérie interne du corps, le premier volet étant sélectivement déplacé de sa position de repos vers une position d'autorisation par toute clef adaptée présentant, suivant le plan transversal à l'axe longitudinal, une section d'épaisseur adaptée à la serrure et pour laquelle le premier volet échappe à la gorge interne, et le premier volet étant sélectivement déplacé de sa position de repos vers une première position décalée par toute clef inadaptée ou fausse clef présentant, suivant le plan transversal à l'axe longitudinal, une section d'épaisseur supérieure à l'épaisseur adaptée à la serrure et pour laquelle un premier élément de bord externe du premier volet tombe dans la gorge interne et interdit une translation du barillet.More specifically, the invention, according to a first of its aspects, relates to a safety lock, comprising a substantially cylindrical body, elongate along a longitudinal axis, a cylinder having a key inlet and mounted in the body rotated around the longitudinal axis and in translation along the longitudinal axis in a direction of introduction of the key, from a rest position to which it is resiliently biased, at least a first concealment flap of the input of key, mounted movably in the body in a plane transverse to the longitudinal axis, and elastically biased towards a rest position by a centripetal elastic force, and an internal groove made in an inner periphery of the body, the first component being selectively displaced from its rest position to an authorization position by any suitable key having, in the plane transverse to the longitudinal axis, a thick section ad keyed to the lock and for which the first flap escapes the internal groove, and the first flap is selectively moved from its rest position to a first position offset by any unsuitable key or false key having, in the plane transverse to the axis longitudinal, a section thicker than the thickness adapted to the lock and for which a first outer edge member of the first flap falls into the internal groove and prohibits a translation of the barrel.

Des serrures de sûreté de ce type sont connues depuis de nombreuses années, comme en témoignent par exemple les documents de brevets FR - 2 552 146 et FR - 2 552 147.Safety locks of this type have been known for many years, as evidenced, for example, by patent documents FR-2,552,146 and FR-2,552,147.

Bien que ces serrures aient jusqu'à présent donné la plus grande satisfaction, notamment quant au niveau de sûreté qu'elles offrent, le développement de machines numériques de reproduction de clefs fait naître, au moins à terme, le besoin d'augmenter la sélectivité de ces serrures.Although these locks have so far given the greatest satisfaction, especially as to the level of safety they offer, the development of machines Digital reproduction of keys gives rise, at least in the long term, the need to increase the selectivity of these locks.

Dans ce contexte, la présente invention a précisément pour but, selon un premier de ses aspects, de proposer une serrure de sélectivité accrue.In this context, the present invention specifically aims, according to a first aspect, to provide an increased selectivity lock.

La serrure de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisée en ce que le premier volet présente un second élément de bord externe par lequel il est engagé dans la gorge interne au moins lorsqu'il est placé dans une position comprise dans une plage de positions intermédiaires entre sa position de repos et sa position d'autorisation, et en ce que le premier volet est monté à rotation sur le barillet autour d'un axe secondaire parallèle à l'axe longitudinal et décalé par rapport à lui vers une périphérie du barillet, cet axe secondaire étant disposé dans un plan axial passant entre les premier et second éléments de bord externe du premier volet.The lock of the invention, furthermore in conformity with the generic definition given in the preamble above, is essentially characterized in that the first flap has a second external edge element through which it is engaged in the internal groove at least when it is placed in a position within a range of intermediate positions between its rest position and its authorization position, and in that the first flap is rotatably mounted on the cylinder around a secondary axis parallel to the longitudinal axis and offset from it towards a periphery of the barrel, this secondary axis being disposed in an axial plane passing between the first and second outer edge elements of the first flap.

Bien qu'il soit déjà connu des documents DE 195 09 337 et EP 0 633 373 de tester, dans une serrure de sûreté, une caractéristique de la clef et de la comparer à une limite minimale et à une limite maximale, les organes de test décrits dans ces documents ne sont pas des volets d'occultation déplacés par la clef elle-même, mais des leviers basculants dont chacun est mû par un palpeur en pointe appuyant localement sur la clef.Although it is already known from DE 195 09 337 and EP 0 633 373 to test, in a safety lock, a characteristic of the key and to compare it with a minimum limit and a maximum limit, the test members described in these documents are not occultation flaps moved by the key itself, but tilting levers each of which is moved by a probe tip pressing locally on the key.

Ainsi, alors que le volet d'occultation prévu par l'invention opère une discrimination de la clef en fonction de l'ensemble de la forme de son profil, les leviers basculants décrits dans les documents DE 195 09 337 et EP 0 633 373 ne permettent de tester que l'épaisseur que présente localement la clef à l'endroit où appuient les palpeurs en pointe.Thus, while the occulting flap provided by the invention discriminates the key as a function of the overall shape of its profile, the rocker levers described in the documents DE 195 09 337 and EP 0 633 373 do not make it possible to test that the thickness that locally presents the key to the place where the touch probes support.

De préférence, le premier volet est engagé dans la gorge interne par son second élément de bord externe lorsqu'il occupe sa position de repos et toute position intermédiaire entre sa position de repos et sa position d'autorisation.Preferably, the first flap is engaged in the internal groove by its second outer edge member when it occupies its rest position and any intermediate position between its rest position and its authorization position.

Pour ce faire, le premier volet comporte par exemple un bouton pédonculé formant pivot, centré sur l'axe secondaire, et reçu dans un logement complémentaire du barillet.To do this, the first component comprises for example a pedunculated button forming a pivot, centered on the secondary axis, and received in a complementary housing of the barrel.

Il est possible de prévoir que le premier volet présente un talon portant le premier élément de bord externe et une pointe portant le second élément de bord externe, que le talon présente un bord interne disposé sur l'entrée de clef et sélectivement déplacé par une section de la clef, en fonction de l'épaisseur, de la forme, et/ou de la position de cette section, et que l'axe secondaire soit disposé dans la pointe du premier volet.It is possible to provide that the first flap has a heel bearing the first outer edge member and a tip bearing the second outer edge member, that the heel has an inner edge disposed on the key inlet and selectively moved by a section. of the key, depending on the thickness, shape, and / or position of this section, and that the secondary axis is disposed in the tip of the first flap.

Le bord interne du premier volet peut être chanfreiné pour faciliter l'introduction et le retrait de la clef.The inner edge of the first flap can be chamfered to facilitate insertion and removal of the key.

Dans un mode de réalisation préféré, la serrure de l'invention comprend un second volet identique au premier volet, les premier et second volets adoptant des positions de repos respectives se déduisant l'une de l'autre par rotation autour de l'axe longitudinal.In a preferred embodiment, the lock of the invention comprises a second flap identical to the first flap, the first and second flaps adopting respective rest positions being deduced from each other by rotation around the longitudinal axis. .

Cette serrure peut également comprendre un bracelet ressort précontraint en extension et engagé dans des gorges périphériques externes respectives des premier et second volets pour exercer la force élastique centripète sur ces deux volets.This lock may also include a prestressed spring strap extended and engaged in respective outer peripheral grooves of the first and second components to exert the centripetal elastic force on these two components.

Pour parfaire la cinématique de ces volets, le talon de chaque volet et la pointe de l'autre volet peuvent s'interpénétrer lorsque ces volets sont dans leur position de repos.To perfect the kinematics of these shutters, the heel of each flap and the tip of the other flap can interpenetrate when these flaps are in their rest position.

La serrure de sûreté de l'invention comprend essentiellement, de façon connue, un corps cylindrique 1, un barillet 2, et un ou plusieurs volets tels que 3 et 4.The safety lock of the invention essentially comprises, in known manner, a cylindrical body 1, a barrel 2, and one or more shutters such as 3 and 4.

Le corps 1, de forme générale cylindrique, est allongé suivant un axe longitudinal X et fermé par une face 10 dans laquelle est percé un orifice 12 permettant l'introduction d'une clef, telle que la clef 5 illustrée à la figure 5.The body 1, of generally cylindrical shape, is elongate along a longitudinal axis X and closed by a face 10 in which is pierced an orifice 12 allowing the introduction of a key, such as the key 5 illustrated in FIG.

Par ailleurs, ce corps 1 porte, dans sa périphérie interne 100, une gorge interne 11.Moreover, this body 1 carries, in its inner periphery 100, an internal groove 11.

Le barillet 2 est monté à translation dans le corps 1 le long de l'axe X, suivant une direction D d'introduction de la clef 5, et à l'encontre d'une force élastique qui le rappelle dans une position de repos pour laquelle il s'appuie sur la face 71 d'une garniture 7, cette garniture s'appuyant elle-même contre la face 10 du corps 1.The barrel 2 is mounted in translation in the body 1 along the axis X, in a direction D of introduction of the key 5, and against an elastic force which remembers it in a rest position for which it rests on the face 71 of a lining 7, this lining itself leaning against the face 10 of the body 1.

Le barillet 2, qui présente une entrée de clef 20, est également monté à rotation dans le corps 1 autour de l'axe longitudinal X.The barrel 2, which has a key inlet 20, is also rotatably mounted in the body 1 about the longitudinal axis X.

Chacun des volets tels que 3 et 4 permet d'occulter l'entrée de clef 20, est monté mobile dans le corps 1 dans un plan Pt transversal à l'axe longitudinal X, et est élastiquement rappelé vers une position de repos par une force élastique centripète, c'est-à-dire une force qui sollicite chaque volet vers l'axe longitudinal X.Each of the shutters such as 3 and 4 makes it possible to conceal the key entry 20, is movably mounted in the body 1 in a plane Pt transverse to the longitudinal axis X, and is elastically biased towards a rest position by a force centripetal elastic, that is to say a force that urges each flap towards the longitudinal axis X.

La garniture 7, disposée entre le barillet 2 et la face 10 du corps 1, est elle-même percée d'un passage 70 pour la clef 5.The lining 7, disposed between the barrel 2 and the face 10 of the body 1, is itself pierced with a passage 70 for the key 5.

Chacun des volets 3 et 4 peut, de façon connue, adopter au moins trois positions, à savoir la position de repos précédemment évoquée, dans laquelle ce volet obture au moins partiellement l'entrée de clef 20, une position d'autorisation dans laquelle ce volet échappe à la gorge interne 11 et autorise la translation du barillet 2 par rapport au corps 1, et une première position décalée, dans laquelle ce volet tombe dans la gorge interne 11 et interdit la translation du barillet 2 par rapport au corps 1.Each of the shutters 3 and 4 may, in a known manner, adopt at least three positions, namely the previously mentioned rest position, in which this shutter at least partially closes the key inlet 20, an authorization position in which this flap escapes the internal groove 11 and allows the translation of the barrel 2 relative to the body 1, and a first offset position, in which the flap falls into the internal groove 11 and prohibits the translation of the barrel 2 relative to the body 1.

Plus précisément, chaque volet tel que 3 et 4 est déplacé de sa position de repos vers sa position d'autorisation par toute clef adaptée à la serrure, c'est-à-dire par une clef présentant, suivant le plan Pt transversal à l'axe longitudinal X (figure 2), une section 50 d'épaisseur maximale E adéquate pour la serrure considérée (figure 4).More specifically, each component such as 3 and 4 is moved from its rest position to its authorized position by any key adapted to the lock, that is to say by a key having, according to the plane Pt transverse to the longitudinal axis X (Figure 2), a section 50 of maximum thickness E adequate for the lock in question (Figure 4).

Chaque volet tel que 3 et 4 est déplacé de sa position de repos vers sa première position décalée par toute clef de géométrie inadaptée à la serrure et toute fausse clef, et notamment par une clef ou substitut de clef présentant, suivant le plan Pt transversal à l'axe longitudinal X, une section 50 d'épaisseur supérieure à l'épaisseur E adéquate pour la serrure considérée.Each shutter such as 3 and 4 is moved from its rest position to its first position offset by any geometric key unsuited to the lock and any false key, and in particular by a key or key substitute having, according to the plane Pt transverse to axis longitudinal X, a section 50 of greater thickness than the appropriate thickness E for the lock considered.

Dans ce dernier cas (figures 8 et 9), chaque volet tel que 3 et 4 tombe dans la gorge interne 11 par un premier élément de bord externe, tel que 31 et 41, de ce volet, et interdit une translation du barillet 2 par rapport au corps 1.In the latter case (FIGS. 8 and 9), each shutter such as 3 and 4 falls into the internal groove 11 by a first external edge element, such as 31 and 41, of this shutter, and prohibits a translation of the barrel 2 by relation to the body 1.

Selon l'invention (figures 10 et 11), l'un au moins des volets, et de préférence chaque volet tel que 3 et 4, présente un second élément de bord externe, tel que 32 et 42, par lequel il est engagé dans la gorge interne 11 au moins lorsqu'il est placé dans une position comprise dans une plage de positions intermédiaires entre sa position de repos et sa position d'autorisation.According to the invention (FIGS. 10 and 11), at least one of the flaps, and preferably each flap such as 3 and 4, has a second external edge element, such as 32 and 42, through which it is engaged in the internal groove 11 at least when it is placed in a position within a range of intermediate positions between its rest position and its authorization position.

Selon l'invention, au moins un volet 3, 4 est engagé dans la gorge interne 11 par son second élément de bord externe 32, 42 lorsqu'il occupe sa position de repos (figures 10 et 11) et toute position intermédiaire entre sa position de repos et sa position d'autorisation.According to the invention, at least one flap 3, 4 is engaged in the internal groove 11 by its second outer edge member 32, 42 when it occupies its rest position (FIGS. 10 and 11) and any intermediate position between its position rest and its authorization position.

Selon l'invention, (figures 1, 6, 8, 10), au moins un volet 3, 4 est monté à rotation sur le barillet 2 autour d'un axe secondaire XX parallèle à l'axe longitudinal X du corps 1.According to the invention, (FIGS. 1, 6, 8, 10), at least one flap 3, 4 is rotatably mounted on the barrel 2 about a secondary axis XX parallel to the longitudinal axis X of the body 1.

Selon l'invention, chaque axe secondaire XX est décalé par rapport à l'axe longitudinal X du corps 1 vers la périphérie 200 du barillet 2, et est disposé dans un plan axial Pa (figure 6) qui passe entre les premier et second éléments de bord externe, tels que 31, 32 et 41, 42, d'au moins un volet 3, 4.According to the invention, each secondary axis XX is offset relative to the longitudinal axis X of the body 1 towards the periphery 200 of the barrel 2, and is disposed in an axial plane Pa (FIG. 6) which passes between the first and second elements outer edge, such as 31, 32 and 41, 42, of at least one flap 3, 4.

Pour ce faire, chaque volet 3, 4 comporte par exemple un bouton pédonculé, tel que 33, 43, formant pivot, centré sur l'axe secondaire XX correspondant, et reçu dans un logement complémentaire correspondant 23 du barillet 2.To do this, each flap 3, 4 comprises for example a pedunculated button, such as 33, 43, pivoting, centered on the corresponding secondary axis XX, and received in a corresponding complementary housing 23 of the barrel 2.

Comme le montrent notamment les figures 6, 8, et 10, chaque volet tel que 3 et 4, présente un talon tel que 34 et 44, et une pointe telle que 35 et 45, l'axe secondaire XX de chaque volet 3 et 4 étant disposé dans la pointe 35, 45 de ce volet.As shown in particular in Figures 6, 8, and 10, each component such as 3 and 4, has a heel such as 34 and 44, and a tip such as 35 and 45, the axis secondary XX of each component 3 and 4 being disposed in the tip 35, 45 of this component.

Le talon 34, 44 de chaque volet 3, 4 porte le premier élément de bord externe 31, 41 de ce volet, tandis que la pointe 35, 45 de ce même volet porte le second élément de bord externe 32, 42 correspondant.The heel 34, 44 of each flap 3, 4 carries the first outer edge member 31, 41 of this flap, while the tip 35, 45 of the same flap carries the corresponding second outer edge member 32, 42.

Chaque talon 34, 44 présente par ailleurs un bord interne, tel que 340 et 440, qui est disposé sur l'entrée de clef 20 et qui est déplacé par la section réduite 50 de la clef 5, en fonction de l'épaisseur, de la forme et/ou de la position de cette section 50.Each bead 34, 44 also has an inner edge, such as 340 and 440, which is disposed on the keyway 20 and which is displaced by the reduced section 50 of the key 5, depending on the thickness, the shape and / or position of this section 50.

Comme le montre notamment la figure 7, le bord interne 340, 440 de chaque volet 3, 4 est avantageusement chanfreiné pour faciliter l'introduction et le retrait de la clef 5.As shown in particular in FIG. 7, the inner edge 340, 440 of each shutter 3, 4 is advantageously chamfered to facilitate the insertion and removal of the key 5.

Les volets d'obturation 3 et 4 sont de préférence au nombre de deux et adoptent des positions de repos respectives qui se déduisent l'une de l'autre par une rotation de 180 degrés autour de l'axe longitudinal X.The shutters 3 and 4 are preferably two in number and adopt respective rest positions which are deduced from each other by a rotation of 180 degrees around the longitudinal axis X.

La force centripète qui sollicite élastiquement les volets 3 et 4 vers leur position de repos est par exemple exercée par un bracelet ressort 6 (figures 1 et 7 notamment), précontraint en extension, et engagé dans des gorges périphériques externes respectives 36 et 46 de ces volets 3 et 4.The centripetal force which resiliently biases the flaps 3 and 4 towards their rest position is for example exerted by a spring strap 6 (FIGS. 1 and 7 in particular), prestressed in extension, and engaged in respective external peripheral grooves 36 and 46 of these shutters 3 and 4.

Chaque volet 3, 4 présente de préférence (figures 1, 11 et 15) une excroissance telle que 341 et 441 formée sur son talon 34, 44, et un lamage tel que 351 et 451 formé dans sa pointe, de manière que, dans la position de repos de ces volets, le talon 34 et 44 de chaque volet et la pointe 45 et 35 de l'autre volet s'interpénètrent, par pénétration d'une des excroissances dans celui des deux lamages qui lui est adjacent.Each flap 3, 4 preferably has (FIGS. 1, 11 and 15) an outgrowth such as 341 and 441 formed on its heel 34, 44, and a countersink such as 351 and 451 formed in its tip, so that, in the rest position of these flaps, the heel 34 and 44 of each flap and the tip 45 and 35 of the other flap interpenetrate by penetration of one of the excrescences in that of the two countersinks adjacent thereto.

Une clef 5 (figure 5) ou une ébauche de clef 500 (figures 2 et 3) utilisable pour l'actionnement d'une serrure telle que précédemment décrite comprend, de façon connue, une tige 51 manoeuvrable à la main et orientée, en fonctionnement, suivant l'axe longitudinal X de la serrure, et un panneton 52 porté par une extrémité 510 de la tige 51 pour actionner la serrure.A key 5 (FIG. 5) or a key blank 500 (FIGS. 2 and 3) that can be used for actuating a lock as previously described comprises, in a known manner, a rod 51 operable by hand and oriented, operating, along the longitudinal axis X of the lock, and a bit 52 carried by an end 510 of the rod 51 to actuate the lock.

De façon également connue, le panneton 52 présente (figure 2), dans le plan Pt transversal à l'axe longitudinal X, une section réduite 50 au moins partiellement dessinée par une rainure 53 qui y est creusée.Also known, the blade 52 has (Figure 2) in the plane Pt transverse to the longitudinal axis X, a reduced section 50 at least partially drawn by a groove 53 which is hollowed.

La section réduite 50 est dissymétrique par rapport à tout plan parallèle à l'axe longitudinal X.The reduced section 50 is asymmetrical with respect to any plane parallel to the longitudinal axis X.

Par exemple, la section réduite 50 admet l'axe longitudinal X comme axe de symétrie de rotation, et est en l'occurrence invariante par rotation de 180 degrés autour de l'axe X.For example, the reduced section 50 admits the longitudinal axis X as axis of rotation symmetry, and is in this case invariant by rotation of 180 degrees around the axis X.

Comme le montre la figure 4, la section réduite 50 peut s'étendre le long d'un parcours moyen M et peut aussi, de façon non limitative, présenter, perpendiculairement à ce parcours moyen M, une épaisseur E sensiblement constante, indépendamment de la largeur globale L que présente cette section 50.As shown in FIG. 4, the reduced section 50 may extend along an average path M and may also, in a nonlimiting manner, present, perpendicularly to this average path M, a substantially constant thickness E, independently of the overall width L in this section 50.

Le parcours moyen M peut se développer suivant une courbe arrondie ou en zigzags, mais présente de préférence une forme sinueuse dans tous les cas de figure.The average path M can develop in a rounded curve or zigzags, but preferably has a sinuous shape in all cases.

La clef ou l'ébauche de clef ainsi définie est avantageusement réalisée par matriçage, au moins en partie.The key or the key blank thus defined is advantageously made by stamping, at least in part.

Dans ces conditions, si l'épaisseur de la section 50 de la clef utilisée pour provoquer le déplacement des volets 3 et 4 de la serrure, ou à défaut l'épaisseur de l'outil de crochetage, sont surdimensionnées par rapport à l'épaisseur E (figure 4) que présente la clef adaptée à la serrure, alors les premiers éléments de bord 31 et 41 des volets 3 et 4 tombent, comme c'est également le cas pour la serrure décrite dans le document de brevet FR - 2 552 147, dans la gorge interne 11 et interdisent la translation du barillet 2 par rapport au corps 1 de la serrure, donc l'actionnement de celle-ci.Under these conditions, if the thickness of the section 50 of the key used to cause the displacement of the flaps 3 and 4 of the lock, or the thickness of the picking tool, are oversized relative to the thickness E (Figure 4) that presents the key adapted to the lock, then the first edge elements 31 and 41 of the shutters 3 and 4 fall, as is also the case for the lock described in the patent document FR - 2 552 147, in the internal groove 11 and prohibit the translation of the barrel 2 relative to the body 1 of the lock, so the actuation thereof.

Et si l'épaisseur de la section 50 de la clef utilisée pour provoquer le déplacement des volets 3 et 4, ou à défaut l'épaisseur de l'outil de crochetage, sont sous-dimensionnées par rapport à l'épaisseur E que présente la clef adaptée à la serrure, alors ce sont, conformément à l'invention, les seconds éléments de bord 32 et 42 des volets 3 et 4 qui tombent dans la gorge interne 11 et qui interdisent la translation du barillet 2 par rapport au corps 1 de la serrure, donc l'actionnement de celle-ci.And if the thickness of the section 50 of the key used to cause the displacement of the flaps 3 and 4, or if the thickness of the picking tool, are undersized compared to the thickness E that presents the key adapted to the lock, then it is, according to the invention, the second edge members 32 and 42 of the shutters 3 and 4 which fall into the internal groove 11 and which prohibit the translation of the barrel 2 relative to the body 1 of the lock, so the actuation thereof.

Mais la sélectivité de la serrure de l'invention n'est pas seulement accrue par la mise en place d'une limite inférieure d'épaisseur en plus de la limite supérieure : elle l'est également par un effet de forme, comme permet de le comprendre la figure 4, supposée représenter la section réduite 50 d'une clef ou d'une ébauche adaptée à la serrure considérée.But the selectivity of the lock of the invention is not only increased by the introduction of a lower limit of thickness in addition to the upper limit: it is also increased by a shape effect, as allows 4, which is assumed to represent the reduced section 50 of a key or a blank adapted to the lock in question.

En effet, si la section réduite d'une autre clef d'une autre ébauche, bien que présentant l'épaisseur E adaptée à la serrure, présente une forme inadaptée, la course effectuée par les volets 3 et 4 à partir de leur position de repos sous l'effet de l'introduction de cette autre clef ou ébauche sera surdimensionnée par contact avec les volets dans les zones 501 si le parcours moyen M de la section de cette autre clef ou ébauche est moins courbe que celui de la figure 4, et sera surdimensionnée par contact avec les volets dans les zones 502 si le parcours moyen M de la section de cette autre clef ou ébauche est plus courbe que celui de la figure 4.Indeed, if the reduced section of another key of another blank, although having the thickness E adapted to the lock, has an unsuitable shape, the stroke performed by the shutters 3 and 4 from their position of rest under the effect of the introduction of this other key or blank will be oversized by contact with the flaps in the zones 501 if the average path M of the section of the other key or blank is less curved than that of FIG. 4, and will be oversized by contact with the flaps in the zones 502 if the average path M of the section of this other key or blank is more curved than that of FIG. 4.
