Description

La présente invention concerne un dispositif de limitation d'accès à la serrure d'un mécanisme verrouillable, notamment d'une barrière pivotante.The present invention relates to a device for limiting access to the lock of a lockable mechanism, in particular a pivoting barrier.

Certains mécanismes verrouillables, notamment les barrières pivotantes équipant des voies d'accès, doivent pouvoir être déverrouillés uniquement par les personnes autorisées et être protégés à l'égard des tentatives de déverrouillage susceptibles d'être opérées par des personnes non autorisées.Certain lockable mechanisms, such as pivoting barriers on access routes, must be unlockable only by authorized persons and protected against unlocking attempts by unauthorized persons.

Il n'existe pas à ce jour sur le marché de dispositif permettant de limiter l'accès à la serrure d'un tel mécanisme verrouillable, qui donne toute satisfaction en pratique, particulièrement pour une application à des barrières pivotantes équipant des voies d'accès. Un objectif principal de l'invention est de remédier à cette lacune.There is currently no device on the market to limit access to the lock of such a lockable mechanism, which is satisfactory in practice, particularly for application to pivoting barriers equipping access ways . A main objective of the invention is to remedy this deficiency.

La demande de brevet français n° 03 01247 , déposée au nom de la demanderesse, décrit une barrière pivotante pouvant être équipé du dispositif selon la présente invention. Cette barrière 1, représentée sur la figure 1, comprend un pilier ancré au sol au moyen d'une embase 2, un fût 3 solidaire d'un bras 4 engagé à pivotement sur le pilier, et un mécanisme verrouillable situé entre la tête du pilier et la paroi de fond du fût 3, permettant le verrouillage/déverrouillage du pivotement du fût 3 par rapport au pilier.The patent application French No. 03 01247 , filed in the name of the applicant, describes a pivotable barrier that can be equipped with the device according to the present invention. This barrier 1, shown in Figure 1, comprises a pillar anchored to the ground by means of a base 2, a shaft 3 secured to an arm 4 pivotally engaged on the pillar, and a lockable mechanism located between the head of the pillar and the bottom wall of the barrel 3, allowing the locking / unlocking of the pivoting of the barrel 3 relative to the pillar.

Le fût 3 comprend un trou 5 pour l'engagement d'une clé de verrouillage/déverrouillage de la barrière 1, visible sur la figure 2. Cette clé 6 comprend une partie de préhension 6a, un axe intermédiaire 6b et une partie terminale élargie 6c. Une cavité de profil spécifique, par exemple de section triangulaire dans l'exemple représenté, est aménagée dans cette partie terminale élargie 6c.The barrel 3 comprises a hole 5 for the engagement of a key for locking / unlocking the barrier 1, visible in FIG. 2. This key 6 comprises a gripping portion 6a, an intermediate axis 6b and an enlarged end portion 6c. . A cavity of specific profile, for example of triangular section in the example shown, is arranged in this enlarged end portion 6c.

Le mécanisme de commande est visible en perspective éclatée sur la figure 2. Il est porté par une platine 10 reliée à la paroi 3a de fond du fût 3, et comprend notamment un doigt de verrouillage 11 mobile verticalement, qui coopère avec des trous de verrouillage aménagés au niveau de la tête du pilier. L'engagement du doigt 11 dans l'un de ces trous, de plus grande profondeur, permet de verrouiller la barrière 1 en position de fermeture et l'engagement de ce même doigt 11 dans un autre de ces trous, de profondeur réduite, permet de maintenir la barrière 1 en position d'ouverture.The control mechanism is visible in exploded perspective in FIG. 2. It is carried by a plate 10 connected to the bottom wall 3a of the drum 3, and notably comprises a vertically movable locking pin 11 which cooperates with locking holes. arranged at the level of the head of the pillar. The engagement of the finger 11 in one of these holes, of greater depth, makes it possible to lock the barrier 1 in the closed position and the engagement of this same finger 11 in another of these holes, of reduced depth, allows to maintain the barrier 1 in the open position.

Le mécanisme de commande comprend également un axe 12 comportant une extrémité de profil complémentaire de celui de la cavité de la clé 6, un manchon 13 pourvu d'un doigt radial de commande 14, ce doigt 14 étant, après montage, engagé dans une encoche 15 que comprend un étrier 16 solidaire du doigt de verrouillage 11.The control mechanism also comprises an axis 12 comprising a profile end complementary to that of the cavity of the key 6, a sleeve 13 provided with a radial control finger 14, this finger 14 being, after assembly, engaged in a notch 15 that comprises a stirrup 16 secured to the locking finger 11.

La paroi centrale de l'étrier 16 comprend une encoche 17 dont la portion supérieure est en V et permet le passage de ladite partie élargie 6c de la clé 6, et dont la portion inférieure est en U et présente une largeur supérieure à la largeur dudit axe intermédiaire 6b mais inférieure à la largeur de la partie 6c. Il se comprend en référence à la figure 2 que, dans une position basse de l'étrier 16 et du doigt 11, la clé 6 peut être engagée sur l'axe 12 et être calée en rotation par rapport à celui-ci, et que, dans une position haute de cet étrier 16 et du doigt 11, la clé 6 est retenue sur l'axe 12 par l'étrier 16. Dans cette position basse, le doigt 11 dépasse en dessous de la platine 10, au travers d'un trou 18 aménagé dans celle-ci, et vient se loger dans le trou profond précité, tandis que, dans ladite position haute, le doigt 11 ne dépasse pas en dessous de la platine 10, permettant le pivotement de ce même ensemble par rapport au pilier.The central wall of the stirrup 16 comprises a notch 17 whose upper portion is V and allows the passage of said enlarged portion 6c of the key 6, and whose lower portion is U-shaped and has a width greater than the width of said intermediate axis 6b but less than the width of part 6c. It is understood with reference to FIG. 2 that, in a low position of the stirrup 16 and of the finger 11, the key 6 can be engaged on the spindle 12 and be wedged in rotation with respect thereto, and that in a high position of this stirrup 16 and the finger 11, the key 6 is retained on the axis 12 by the stirrup 16. In this low position, the finger 11 protrudes below the plate 10, through a hole 18 formed in it, and is housed in the aforesaid deep hole, while in said high position, the finger 11 does not protrude below the plate 10, allowing the pivoting of the same assembly relative to the pillar.

La barrière 1 décrite ci-dessus donne satisfaction en pratique mais a pour inconvénient de n'être adaptée qu'à un seul type de clé. Or, il s'avère que certains utilisateurs, notamment les pompiers, utilisent un autre type de clé, à savoir une clé multifonctionnelle normalisée, couramment dénommée "tricoise" ou "polycoise", représentée sur la figure 3. Cette clé 20 comprend des extrémités de commande de serrures, à savoir une extrémité mâle triangulaire 21, une extrémité mâle carrée 22, une extrémité femelle 23 à empreinte triangulaire et une extrémité femelle 24 à empreinte carrée. Cette clé 20 comprend également une branche 25 dont un des bords latéral 26 est courbe et se termine par un ergot 27 ; cet ergot 27 est destiné à venir en prise avec un épaulement correspondant aménagé sur un embout de tuyau, la clé 20 étant utilisée comme un levier pour visser ou dévisser cet embout.The barrier 1 described above is satisfactory in practice but has the disadvantage of being adapted to only one type of key. However, it turns out that some users, including firefighters, use another type of key, namely a standard multifunctional key, commonly referred to as "tricoise" or "polycoise", shown in Figure 3. This key 20 includes ends lock control device, namely a triangular male end 21, a square male end 22, a female end 23 with triangular imprint and a female end 24 with square imprint. This key 20 also comprises a branch 25, one of the lateral edges 26 is curved and ends with a lug 27; this lug 27 is intended to engage with a corresponding shoulder arranged on a pipe end, the key 20 being used as a lever for screwing or unscrewing this tip.

Le document DE 200 16 845 U1 décrit un volet pivotant 2 de recouvrement d'une serrure 5 montée dans un corps cylindrique 1, ce montage étant réalisé au moyen de vis 4. Le volet 2 est maintenu normalement en position de fermeture par un système 6 plus particulièrement visible sur les figures 4 à 7 de ce document.The document DE 200 16 845 U1 discloses a pivoting flap 2 for covering a lock 5 mounted in a cylindrical body 1, this mounting being carried out by means of screws 4. The flap 2 is normally held in the closed position by a system 6 that can be seen more particularly in FIGS. to 7 of this document.

Dans la version selon les figures 4 et 5 de ce document, le système 6 comprend un doigt 7 équipé d'un aimant 9 et sollicité par un ressort 8 ; ce doigt est normalement dans la position montrée sur la figure 4 mais, lorsqu'un aimant 10 est approché du volet 2 de manière à attirer l'aimant 9, le doigt 7 est effacé, libérant le pivotement du volet 2.In the version according to Figures 4 and 5 of this document, the system 6 comprises a finger 7 equipped with a magnet 9 and biased by a spring 8; this finger is normally in the position shown in Figure 4 but, when magnet 10 is approached to the shutter 2 so as to attract the magnet 9, the finger 7 is erased, releasing the pivoting of the shutter 2.

Dans la version selon les figures 6 et 7 de ce document, un dispositif électromagnétique 11, situé du côté opposé au volet 2, dans l'intérieur du corps 1, comprend une bobine 12 et une "ancre" 13, c'est-à-dire une sorte de piston, équipé d'un doigt terminal ; ce doigt est engagé au travers d'un trou aménagé dans le corps 1 et, lorsque la bobine 12 est alimentée en électricité, est déplacé de la position montrée sur la figure 6 à la position montrée sur la figure 7 ; dans sa dernière position, ce doigt appui sur le doigt 7 et réalise l'effacement de ce dernier, autorisant ainsi le pivotement du volet 2.In the version according to FIGS. 6 and 7 of this document, an electromagnetic device 11, situated on the side opposite the flap 2, inside the body 1, comprises a coil 12 and an "anchor" 13, that is to say to say a kind of piston, equipped with a terminal finger; this finger is engaged through a hole in the body 1 and, when the coil 12 is supplied with electricity, is moved from the position shown in Figure 6 to the position shown in Figure 7; in its last position, this finger bears on the finger 7 and realizes the erasure of the latter, thereby allowing the flap 2 to pivot.

Le dispositif 6 selon ce document antérieur ne répond pas au besoin mentionné plus haut, d'actionnement par plusieurs types de clés.The device 6 according to this prior document does not meet the need mentioned above, actuation by several types of keys.

L'objectif de l'invention est donc de fournir un dispositif répondant à ce besoin.The object of the invention is therefore to provide a device that meets this need.

Un objectif supplémentaire de l'invention est de fournir un dispositif permettant un déverrouillage d'urgence par une clé spécifique, notamment ce type de clé "tricoise" ou "polycoise".An additional object of the invention is to provide a device for emergency unlocking by a specific key, including this type of key "tricoise" or "polycoise".

  • une zone de prise est aménagée sur le volet, permettant de prendre appui contre ce volet de manière à l'entraîner en rotation vers sa position d'effacement, provoquant ainsi la rupture de la goupille, cet entraînement en rotation étant réalisé au moyen d'une clé spécifique détenue par un utilisateur autorisé, tel qu'un pompier, qui comprend une zone de prise complémentaire de celle que comprend le volet.
According to the invention,
  • these holding means comprise a pin engaged, in the active position of the flap, through this flap and through a part integral with said wall, and
  • a gripping zone is arranged on the flap, making it possible to bear against this flap so as to drive it in rotation towards its erasing position, thereby causing the pin to break, this rotational drive being carried out by means of a specific key held by an authorized user, such as a firefighter, which includes a catch zone complementary to that included in the flap.

Ainsi, la serrure est normalement masquée par le volet, lequel est immobilisé par rapport à ladite paroi au moyen de ladite goupille ; en cas de nécessité, un utilisateur autorisé, disposant de ladite clé spécifique, pourra prendre appui contre le volet et forcer le pivotement de ce dernier vers sa position d'effacement, rompant de ce fait la goupille, afin de pouvoir accéder à la serrure et déverrouiller le mécanisme.Thus, the lock is normally hidden by the flap, which is immobilized relative to said wall by means of said pin; if necessary, an authorized user, with said specific key, can bear against the flap and force the pivoting of the latter to its erasing position, thereby breaking the pin, in order to access the lock and unlock the mechanism.

Avantageusement, le trou de ladite pièce solidaire de ladite paroi recevant la goupille débouche au travers de cette pièce, et le dispositif comprend une pièce d'occultation de ce trou, montée sur le même pivot que le volet, cette pièce d'occultation étant mobile entre une position active, dans laquelle elle occulte ledit trou, et une position effacée, dans laquelle elle libère ce trou, la pièce d'occultation se trouvant en position active lorsque le volet est en position active et en position effacée lorsque le volet est en position effacée.Advantageously, the hole of said piece integral with said wall receiving the pin opens through this part, and the device comprises a concealment piece of this hole, mounted on the same pivot as the flap, this occulting part being movable between an active position, in which it occults said hole, and an erased position, in which it releases this hole, the occulting part being in the active position when the flap is in the active position and in the erased position when the flap is in position. position cleared.

En position active, la pièce d'occultation fait obstacle à une chasse de la goupille à l'intérieur du mécanisme ; après rupture de la goupille, cette pièce d'occultation vient en position d'effacement et ne fait donc pas obstacle à une chasse du fragment de goupille se trouvant dans ledit trou, afin qu'une nouvelle goupille puisse être mise en place pour rétablir l'interdiction d'accès à la serrure.In the active position, the occulting part prevents the pin from being driven into the mechanism; after breaking the pin, this occultation piece comes into the erasing position and therefore does not prevent a flush of the pin fragment in said hole, so that a new pin can be put in place to restore the prohibition of access to the lock.

Le trou du volet recevant la goupille est de préférence débouchant dans la face extérieure du volet, afin de faciliter la mise en place la goupille ; dans ce cas, ce trou et cette goupille sont avantageusement dimensionnés de telle sorte que la goupille soit introduite avec frottements dans ce trou, afin de prévenir toute extraction de la goupille par l'extérieur. Ces frottements sont cependant tels que, après rupture de la goupille, le fragment de goupille puisse être chassé hors de ce trou.The hole of the flap receiving the pin is preferably opening into the outer face of the flap, to facilitate the establishment of the pin; in this case, this hole and this pin are advantageously dimensioned so that the pin is introduced with friction in this hole, to prevent extraction of the pin from the outside. However, these rubs are such that, after breaking the pin, the pin fragment can be driven out of this hole.

De préférence, ladite zone de prise est constituée par une encoche aménagée dans l'épaisseur du volet, ne débouchant pas dans la face extérieure de ce dernier.Preferably, said engagement zone is constituted by a notch arranged in the thickness of the flap, not opening into the outer face of the latter.

Cette disposition limite la possibilité de prise du volet au moyen d'un outil autre que la clé spécifique précitée.This provision limits the possibility of taking the shutter by means of a tool other than the specific key mentioned above.

De préférence, ladite clé spécifique est une clé dite "tricoise" ou "polycoise", ladite zone de prise étant constituée par une encoche aménagée dans l'épaisseur du volet, propre à recevoir l'ergot que comprend ce type de clé.Preferably, said specific key is a key called "tricoise" or "polycoise", said engagement zone being constituted by a notch arranged in the thickness of the flap, adapted to receive the lug that includes this type of key.

Avantageusement, ladite paroi ou ladite pièce solidaire de cette paroi comprend une éminence latérale formant une butée pour le volet lorsque ce dernier est en position active.Advantageously, said wall or said integral part of this wall comprises a lateral eminence forming a stop for the flap when the latter is in the active position.

Cette position active peut ainsi aisément être trouvée pour la mise en place de la goupille. De plus, cette éminence forme une protection du volet à l'égard d'une tentative de forçage du dispositif qui consisterait à opérer une frappe latérale sur le volet, en vue, soit d'opérer une cassure de la goupille, soit, même, de casser l'axe du volet.This active position can thus easily be found for the establishment of the pin. In addition, this eminence forms a protection of the flap with respect to an attempt to force the device which would consist in making a side strike on the flap, in order to either operate a break of the pin, or, even, to break the axis of the shutter.

L'invention sera bien comprise, et d'autres caractéristiques et avantages de celle-ci apparaîtront, en référence au dessin schématique annexé, représentant, à titre d'exemple non limitatif, une forme de réalisation préférée du dispositif qu'elle concerne.The invention will be better understood, and other features and advantages thereof will appear, with reference to the accompanying drawing, showing, by way of non-limiting example, a preferred embodiment of the device it relates.

La figure 4 est une vue de la partie du fût d'une barrière telle que précitée, de côté et en coupe selon la ligne IV-IV de la figure 5 ;Figure 4 is a view of the portion of the barrel of a barrier as mentioned above, from the side and in section along the line IV-IV of Figure 5;

la figure 5 est une vue de la partie supérieure du fût, en extérieur, par le côté situé sur la gauche à la figure 4 ;Figure 5 is a view of the upper part of the barrel, outside, by the side on the left in Figure 4;

la figure 6 est une vue à échelle agrandie du détail encerclé sur la figure 4 ;Figure 6 is an enlarged view of the detail circled in Figure 4;

la figure 7 est une vue de dessus de la partie supérieure du fût, en coupe selon la ligne VII-VII de la figure 5, etFIG. 7 is a view from above of the upper part of the barrel, in section along the line VII-VII of FIG. 5, and

les figures 8 à 10 sont des vues de côté de cette partie supérieure, en extérieur, du côté opposé à la vue selon la figure 5, dans trois étapes successives d'un déverrouillage d'urgence de la barrière.Figures 8 to 10 are side views of this upper part, outside, the opposite side to the view according to Figure 5, in three successive steps of an emergency unlocking of the barrier.

Les figures représentent une barrière 1 du même type que celle décrite précédemment. Sur les figures 4, 5 et 7, on retrouve le fût 3, la platine 10, le manchon 13, l'étrier 16, le doigt de verrouillage 11 et le trou 5 pour l'engagement de la clé de déverrouillage.The figures represent a barrier 1 of the same type as that described above. In Figures 4, 5 and 7, there is the shaft 3, the plate 10, the sleeve 13, the stirrup 16, the locking pin 11 and the hole 5 for the engagement of the unlocking key.

Dans le mécanisme montré sur ces figures, le manchon 13 est relié à un tube 28 se prolongeant du côté diamétralement opposé au trou 5, dont l'extrémité libre comporte une pastille 29 à empreinte carrée. La paroi du fût 3 présente, en regard de cette extrémité libre, une ouverture permettant l'accès à cette pastille 29, laquelle forme par conséquent une deuxième serrure de manoeuvre du mécanisme de la barrière 1.In the mechanism shown in these figures, the sleeve 13 is connected to a tube 28 extending on the side diametrically opposed to the hole 5, the free end comprises a patch 29 square cavity. The wall of the barrel 3 has, opposite this free end, an opening allowing access to this pellet 29, which therefore forms a second operating lock of the mechanism of the barrier 1.

Cette ouverture est équipée du dispositif 30 selon la présente invention, plus particulièrement visible sur la figure 6. Ce dispositif 30 comprend un corps tubulaire 31 engagé au travers de ladite ouverture et fixé à la paroi du fût 3, un pivot 32 engagé au travers de ce corps 31, un volet 33 solidaire de l'extrémité extérieure de ce pivot 32 et une pièce d'occultation 34 solidaire de l'extrémité intérieure de ce pivot 32.This opening is equipped with the device 30 according to the present invention, more particularly visible in FIG. 6. This device 30 comprises a tubular body 31 engaged through said opening and fixed to the wall of the barrel 3, a pivot 32 engaged through this body 31, a flap 33 integral with the outer end of this pivot 32 and a concealing part 34 integral with the inner end of this pivot 32.

Le corps 31 comprend un trou 35 de réception d'une goupille, débouchant à l'intérieur du fût 3, et, comme le montrent les figures 8 à 10, une éminence latérale 36. Cette dernière comprend un bord rectiligne qui forme une butée limitative du pivotement du volet 33.The body 31 comprises a hole 35 for receiving a pin, opening into the inside of the barrel 3, and, as shown in FIGS. 8 to 10, a lateral eminence 36. The latter comprises a rectilinear edge which forms a limiting abutment the pivoting of the flap 33.

Le volet 33 est mobile en pivotement entre une position active, dans laquelle un bord rectiligne qu'il comprend vient en butée contre le bord rectiligne de l'éminence 36 (figure 8) et interdit ainsi l'accès à la serrure, et une position d'effacement, dans laquelle il libère cette ouverture pour permettre l'accès à la serrure (figure 10).The flap 33 is pivotally movable between an active position, in which a rectilinear edge that it comprises abuts against the rectilinear edge of the eminence 36 (FIG. 8) and thus prevents access to the lock, and a position erase, in which it releases this opening to allow access to the lock (Figure 10).

Le volet 33 comprend un trou 37 propre à recevoir une goupille 40, débouchant dans sa face extérieure, qui, en position active du volet, vient en coïncidence du trou 35 du corps 31.The flap 33 comprises a hole 37 adapted to receive a pin 40, opening into its outer face, which, in the active position of the flap, coincides with the hole 35 of the body 31.

Les trous 35, 37 sont dimensionnés de telle sorte que la goupille 40 soit introduite avec frottements en eux, afin de prévenir toute extraction de cette goupille par l'extérieur.The holes 35, 37 are dimensioned such that the pin 40 is introduced with friction in them, to prevent any extraction of this pin from the outside.

Le volet 33 comprend également une zone de prise constituée par une encoche 38 aménagée dans son épaisseur, ne débouchant pas sur l'extérieur du volet, cette encoche 38 étant propre à recevoir l'ergot 27 que comprend une clé 20 (cf. figure 9).The flap 33 also comprises a gripping zone constituted by a notch 38 arranged in its thickness, not opening on the outside of the flap, this notch 38 being adapted to receive the lug 27 that comprises a key 20 (see FIG. ).

La pièce d'occultation 34 présente une forme en "haricot", c'est-à-dire propre à s'étendre sur un secteur de plus de 180 degrés autour du tube 28 ; elle est reliée au pivot 32 par une extrémité, et est dimensionnée de telle sorte que son autre extrémité, en position active du volet 33, vient occulter le trou 35.The occulting part 34 has a shape "bean", that is to say, able to extend over a sector of more than 180 degrees around the tube 28; it is connected to the pivot 32 by one end, and is dimensioned so that its other end, in the active position of the flap 33, conceals the hole 35.

En pratique, le volet 33 est maintenu dans sa position active montrée sur la figure 8 par la goupille 40 engagée au travers des trous 35, 37. L'éminence 36 forme une protection du volet 33 à l'égard d'une tentative de forçage du dispositif 30 qui consisterait à opérer une frappe latérale sur le volet 33 en vue soit d'opérer une cassure de la goupille 40 soit, même, de casser le pivot 32.In practice, the flap 33 is held in its active position shown in Figure 8 by the pin 40 engaged through the holes 35, 37. The eminence 36 forms a protection of the flap 33 with respect to a forcing attempt of the device 30 which would consist in making a side strike on the flap 33 in order either to break the pin 40 or even to break the pivot 32.

Le dispositif 30 assure dans cette position une parfaite protection de la serrure à l'égard de toute manipulation non autorisée.The device 30 ensures in this position a perfect protection of the lock against any unauthorized manipulation.

En situation d'urgence, un utilisateur autorisé détenteur d'une clé 20 engage l'ergot 27 de cette clé dans l'encoche 38 et utilise cette clé comme un levier pour forcer sur le volet 33 afin de rompre la goupille 40 (figure 9) ; un accès à la serrure, et donc une possibilité d'ouverture de la barrière 1, est ainsi réalisé.In an emergency, an authorized user holding a key 20 engages the lug 27 of this key in the notch 38 and uses this key as a lever to force on the flap 33 in order to break the pin 40 (FIG. 9 ); an access to the lock, and therefore a possibility of opening the barrier 1, is thus achieved.

Lors de la remise du dispositif 30 dans son état initial, le volet 33, et donc la pièce d'occultation 34 peuvent être pivotés dans une position d'effacement de ce volet 33 et de cette pièce 34, dans laquelle les fragments de la goupille 40 rompue peuvent être facilement chassés hors des trous 35 et 37. Une nouvelle goupille 40 peut alors être mise en place.When the device 30 is returned to its initial state, the flap 33, and thus the occulting part 34, can be pivoted into an erasing position of this flap 33 and this part 34, in which the fragments of the pin 40 broken can easily be driven out of the holes 35 and 37. A new pin 40 can then be put in place.

Comme cela apparaît de ce qui précède, l'invention fournit un dispositif de limitation d'accès à la serrure d'un mécanisme verrouillable, notamment d'une barrière pivotante, présentant l'avantage déterminant de donner toute satisfaction en pratique en ce qui concerne le déverrouillage du mécanisme uniquement par les personnes autorisées et la protection de ce mécanisme à l'égard des tentatives de déverrouillage susceptibles d'être opérées par des personnes non autorisées.As can be seen from the foregoing, the invention provides a device for limiting access to the lock of a lockable mechanism, in particular a pivoting barrier, having the decisive advantage of giving complete satisfaction in practice with regard to the unlocking of the mechanism only by authorized persons and the protection of this mechanism with regard to unlocking attempts that may be made by unauthorized persons.

Il est à noter qu'outre ces avantages, le dispositif permet une chasse facilitée de l'axe 12 (non visible sur les figures) par introduction d'une tige au travers de la pastille 29 et à l'intérieur du tube 28, pour permettre un interchangement de cet axe 12, si nécessaire.It should be noted that, in addition to these advantages, the device makes it easier to flush the spindle 12 (not visible in the figures) by inserting a rod through the pellet 29 and inside the tube 28, so that allow interchange of this axis 12, if necessary.

Il va de soi que l'invention n'est pas limitée à la forme de réalisation décrite ci-dessus à titre d'exemple mais qu'elle s'étend à toutes les formes de réalisations couvertes par les revendications ci-annexées.It goes without saying that the invention is not limited to the embodiment described above by way of example but that it extends to all embodiments covered by the appended claims.
