Description

La présente invention concerne un dispositif de blocage et de mise à disposition de supports d'informations portatifs formé, par exemple, par des clés ou similaires.The present invention relates to a device for blocking and providing portable information carriers formed, for example, by keys or the like.

Dans de nombreux endroits publics ou privés et en particulier dans des clubs ou associations notamment sportifs, une multiplicité de personnes peuvent avoir accès à une multiplicité d'endroits. Dans la pratique actuelle, on affecte à chacune des personnes l'ensemble des moyens, en général constitués par des clés, qui permettent l'actionnement des moyens de fermeture et d'ouverture d'accès aux locaux, aux armoires ou à tous autres éléments devant être protégés par des moyens de fermeture verrouillables. Cette solution présente des inconvénients. Il est en effet nécessaire de reproduire chaque moyen d'actionnement autant de fois qu'il y a de personnes, chaque personne doit transporter avec elle l'ensemble de ces moyens et tes risques de perte sont importants et nécessitent des reproductions.In many public or private places and in particular in clubs or associations in particular sports, a multiplicity of people can have access to a multiplicity of places. In current practice, each of the persons is assigned all of the means, generally constituted by keys, which allow the actuation of the closing and opening means of access to the premises, to the cupboards or to all other elements. to be protected by lockable closure means. This solution has drawbacks. It is indeed necessary to reproduce each actuating means as many times as there are people, each person must carry with them all of these means and your risk of loss is significant and requires reproductions.

Dans les brevets GB-A-1 500 003 et GB-A-2 121 863, ce dernier ayant servi de base pour le préambule de la revendication 1, on a déjà cherché à remédier à ces inconvénients. Ces documents proposent en effet des dispositifs qui comprennent des blocs de sécurité actionnables respectivement par une clé et dont les barillets sont reliés de telle sorte que ces barillets ne peuvent être en même temps dans leur position autorisant l'introduction et l'extraction des clés correspondantes. Ces dispositifs présentent cependant les inconvénients suivants. Les blocs de sécurité sont fixés, indépendamment les uns des autres, grâce à des systèmes vis-écrous, sur des plaques au travers desquelles ils s'étendent de telle sorte que les blocs de sécurité peuvent être aisément démonter par simple dévissage des écrous ou de leur corps.In patents GB-A-1,500,003 and GB-A-2,121,863, the latter having served as a basis for the preamble of claim 1, attempts have already been made to remedy these drawbacks. These documents indeed propose devices which comprise safety blocks which can be actuated respectively by a key and whose barrels are connected so that these barrels cannot be at the same time in their position authorizing the introduction and the extraction of the corresponding keys. . These devices however have the following drawbacks. The safety blocks are fixed, independently of each other, by means of screw-nut systems, on plates through which they extend so that the safety blocks can be easily removed by simply unscrewing the nuts or their body.

La présente invention a notamment pour but de remédier à ces inconvénients et propose un dispositif qui simplifie considérablement le montage des blocs de sécurité et qui en outre leur assure une bonne protection contre leur destruction.The object of the present invention is in particular to remedy these drawbacks and proposes a device which considerably simplifies the mounting of the safety blocks and which also provides them with good protection against their destruction.

Tel qu'il est revendiqué, le dispositif de blocage et de mise à disposition d'un premier support d'informations portatif formé par une clé à l'aide d'un second support d'informations portatif formé par une clé, et réciproquement, comprend des premier et second moyens de réception et de reconnaissance de respectivement lesdits premier et second supports d'informations, ces moyens de réception comprenant des blocs de sécurité disposés parallèlement et formés chacun par un barillet monté dans un élément fixe récepteur de ce barillet, chacune des clés ne pouvant être introduite ou retirée du bloc de sécurité qui lui est associé que lorsque son barillet est dans une position ou orientation déterminée par rapport à son élément fixe récepteur, des moyens étant prévus pour relier en rotation lesdits barillets de telle sorte qu'ils ne puissent se trouver en même temps dans lesdites positions ou orien- talions déterminées d'introduction et d'extraction desdites clés.As claimed, the device for blocking and providing a first portable information carrier formed by a key using a second portable information carrier formed by a key, and vice versa, comprises first and second means for receiving and recognizing said first and second information carriers respectively, these receiving means comprising security blocks arranged in parallel and each formed by a barrel mounted in a fixed element receiving this barrel, each keys which can only be inserted or removed from the safety block associated with it when its barrel is in a determined position or orientation relative to its fixed receiving element, means being provided for connecting said barrels in rotation so that they cannot be at the same time in said determined positions or orientations for the introduction and extraction of said keys.

Conformément à la présente invention, lesdits blocs de sécurité sont disposés parallèlement à l'intérieur d'un boîtier creux, les éléments fixes de ces blocs étant mutuellement en contact et étant en contact avec les faces intérieures des parois latérales et d'extrémité dudit boîtier de manière à assurer leur maintien et leur positionnement l'un par rapport à l'autre et par rapport au boîtier et que les parois d'extrémité dudit boîtier creux présentent des ouvertures d'accès auxdits barillets pour lesdites clés.According to the present invention, said safety blocks are arranged parallel to the interior of a hollow housing, the fixed elements of these blocks being in mutual contact and being in contact with the internal faces of the side and end walls of said housing. so as to ensure their maintenance and positioning relative to each other and relative to the housing and that the end walls of said hollow housing have access openings to said barrels for said keys.

Conformément à la présente invention, ledit boîtier est de section parallèlipipédique.According to the present invention, said housing is of parallelipiped section.

Dans une variante d'exécution, lesdits moyens de liaison sont formés par des bras de levier respectivement liés en rotation auxdits barillets, chacun de ces bras de levier formant butée pour l'autre lorsque l'un se trouve dans ladite orientation déterminée. Ces bras de leviers peuvent être reliés par l'intermédiaire d'une tige ou d'un poussoir.In an alternative embodiment, said connecting means are formed by lever arms respectively linked in rotation to said barrels, each of these lever arms forming a stop for the other when one is in said determined orientation. These lever arms can be connected by means of a rod or a pusher.

La présente invention sera mieux comprise à l'étude d'un dispositif de blocage et de mise à disposition d'une première clé à l'aide d'une seconde clé et réciproquement et comprenant deux blocs de sécurité insérés dans un boîtier, décrit à titre d'exemple non limitatif et illustré sur le dessin sur lequel:

  • - la figure 1 représente une vue longitudinale d'un dispositif selon la présente invention dont les parties d'extrémité sont coupées de manière à faire apparaître d'un côté l'un des blocs et de l'autre côté l'autre bloc.
  • - et la figure 2 représente une coupe transversale selon II-II du dispositif de la figure 1.
The present invention will be better understood from the study of a device for blocking and providing a first key using a second key and vice versa and comprising two security blocks inserted in a housing, described in title of nonlimiting example and illustrated on the drawing on which:
  • - Figure 1 shows a longitudinal view of a device according to the present invention, the end portions are cut so as to show on one side one of the blocks and on the other side the other block.
  • - And Figure 2 shows a cross section along II-II of the device of Figure 1.

Le dispositif représenté sur les figures et repéré d'une manière générale par la référence 1 comprend deux blocs de sécurité repérés d'une manière générale par les références 2 et 3 et représentés en vues extérieures qui comprennent respectivement des éléments cylindriques 4 et 5 dans lesquels sont disposés des barillets 6 et 7, ces blocs de sécurité étant d'un type classique de telle sorte qu'il n'est pas nécessaire de les décrire plus en détail. Ces blocs de sécurité 2 et 3 sont adaptés pour recevoir respectivement les clés 8 et 9 et sont tels que les clés 8 et 9 ne peuvent être introduites dans les barillets 6 et 7 que si ces barillets ont une orientation déterminé par rapport aux éléments cylindriques 4 et 5 et que les barillets 6 et 7 sont bloqués dans cette orientation si les clés 8 et 9 sont extraites.The device shown in the figures and generally identified by the reference 1 comprises two safety blocks generally identified by the references 2 and 3 and shown in external views which respectively comprise cylindrical elements 4 and 5 in which barrels 6 and 7 are arranged, these safety blocks being of a conventional type so that it is not necessary to describe them in more detail. These safety blocks 2 and 3 are adapted to receive the keys 8 and 9 respectively and are such that the keys 8 and 9 can only be introduced into the barrels 6 and 7 if these barrels have a determined orientation relative to the cylindrical elements 4 and 5 and that the barrels 6 and 7 are locked in this orientation if the keys 8 and 9 are extracted.

Les blocs de sécurité 2 et 3 sont disposés parallèlement à l'intérieur d'un boîtier 10 de forme parallélèpipédique dont les parois d'extrémité 11 et 12 présentent respectivement des ouvertures 13 et 14, l'ouverture 13 permettant l'introduction de la clé 8 dans le bloc de sécurité 2 tandis que l'ouverture 14 permet l'introduction de a clé 9 dans le bloc de sécurité 3.The safety blocks 2 and 3 are arranged parallel to the inside of a box 10 of parallelepiped shape, the end walls 11 and 12 of which have openings 13 and 14 respectively, the opening 13 allowing the key to be inserted. 8 in the safety block 2 while the opening 14 allows the introduction of a key 9 in the safety block 3.

Comme on peut le voir sur la figure 2, les blocs de sécurité 2 et 3 sont en contact avec les parois intérieures du boîtier 10 et leurs éléments cylindriques 4 et 5 fixes sont par ailleurs reliés par un élément 15 et sont en appui l'un contre l'autre en vue de leur maintien et de leur positionnement par rapport au boîtier 10 et l'un par rapport à l'autre.As can be seen in FIG. 2, the safety blocks 2 and 3 are in contact with the interior walls of the housing 10 and their cylin elements 4 and 5 fixed pins are also connected by an element 15 and are in abutment against one another in order to maintain and position them relative to the housing 10 and one relative to the other.

Chacun des blocs de sécurité 2 et 3 présente un bras de levier 16 et respectivement 17 qui est lié en rotation à son barillet respectifs 6 et respectivement 7. Ces bras de levier 16 et 17 s'étendent d'un même côté par rapport à leurs axes de rotation parallèles. Les bras de levier 17 porte une tige ou poussoir 18 qui s'étend vers le bras de levier 16 et qui constitué un élément d'écartement liant en rotation les bras de levier 16 et 17 et en conséquence les barillets 6 et 7 de telle sorte que ces bras de levier 16 et 17, et en conséquence les barillets 6 et 7 des blocs de sécurité 2 et 3 sont nécessairement décalés angulairement.Each of the safety blocks 2 and 3 has a lever arm 16 and respectively 17 which is linked in rotation to its respective barrel 6 and respectively 7. These lever arms 16 and 17 extend on the same side with respect to their parallel axes of rotation. The lever arms 17 carries a rod or pusher 18 which extends towards the lever arm 16 and which constitutes a spacer linking in rotation the lever arms 16 and 17 and consequently the barrels 6 and 7 so that these lever arms 16 and 17, and consequently the barrels 6 and 7 of the safety blocks 2 and 3 are necessarily angularly offset.

Le dispositif 1 représenté sur les figures fonctionne de la manière suivante.The device 1 shown in the figures operates as follows.

Lors du montage du dispositif 1, il est nécessaire qu'au moins l'un des blocs de sécurité 2 et 3 soit muni de sa clé. Par exemple, on a monté le dispositif 1 en ayant disposé la clé 9 dans le bloc de sécurité 3 de telle sorte que le barillet 7 et son levier 17 puissent tourner. La clé 8 n'étant pas disposée dans le bloc de sécurité 2, son barillet 6 et son bras de levier 16 sont maintenus dans la position déterminée d'introduction de la clé 8. Grâce à la tige 18, le bras de levier 17 et le barillet 7 sont décalés angulairement par rapport à la position d'introduction ou d'extraction de la clé 9 de telle sorte que cette clé 9 préalablement disposée ne peut pas être extraîte du bloc de sécurité 3. Les barillets 6 et 7, les bras de levier 16 et 17 et la clé 9 sont dans la position représentée sur les figures 1 et 2.When mounting the device 1, it is necessary that at least one of the safety blocks 2 and 3 is provided with its key. For example, the device 1 has been mounted having the key 9 placed in the safety block 3 so that the barrel 7 and its lever 17 can rotate. Since the key 8 is not placed in the safety block 2, its barrel 6 and its lever arm 16 are held in the determined position for introducing the key 8. Thanks to the rod 18, the lever arm 17 and the barrel 7 are angularly offset with respect to the position of insertion or extraction of the key 9 so that this previously arranged key 9 cannot be extracted from the safety block 3. The barrels 6 and 7, the arms lever 16 and 17 and the key 9 are in the position shown in Figures 1 and 2.

Si l'on introduit la clé 8 dans le bloc de sécurité 2, on libère son barillet 6 qui peut alors tourner avec son bras de levier 16. Il s'ensuit qu'il est possible, grâce à la clé 9, de faire pivoter le barillet 7 et so bras de levier 17 du bloc de sécurité 3 jusqu'à sa position d'extration de la clé 9. Lorsque la clé 9 est ramenée dans sa position d'extraction', le barillet 6 et son bras de levier 16, grâce à la tige 18, viennent dans une position décalée angulairement par rapport à la position d'extraction de la clé 8 qui se trouve alors bloquée dans le bloc de sécurité 2. On peut alors, dans cette position, extraire la clé 9 du bloc de sécurité 3. En disposant de nouveau la clé 9 dans le bloc de sécurité 3, on libère en rotation la barillet 7 et son bras de levier 17 de telle sorte qu'il est possible de ramener, grâce à la clé 8, le barillet 6 et son bras de levier 16 dans la position d'extraction de la clé 8 qui peut alors être extraite, la clé 9 se trouvant de nouveau bloquée dans le bloc de sécurité 3 du fait que son barillet 7 et son bras de levier 17 sont décalés angulairement par rapport à la position d'extraction de la clé 9.If the key 8 is introduced into the safety block 2, its barrel 6 is released which can then rotate with its lever arm 16. It follows that it is possible, thanks to the key 9, to pivot the cylinder 7 and so lever arm 17 of the safety block 3 until its extration position of the key 9. When the key 9 is brought into its extraction position ', the cylinder 6 and its lever arm 16 , thanks to the rod 18, come in a position angularly offset from the key extraction position 8 which is then blocked in the safety block 2. We can then, in this position, extract the key 9 from safety block 3. By again placing the key 9 in the safety block 3, the barrel 7 and its lever arm 17 are released in rotation so that it is possible to bring the barrel 6 and its lever arm 16 in the key extraction position 8 which can then be extracted, the key 9 being again blocked in the safety block 3 owing to the fact that its barrel 7 and its lever arm 17 are angularly offset relative to the position for extracting the key 9.

On remarque donc que lorsque les deux clés 8 et 9 sont dans leurs blocs de sécurité respectifs 2 et 3, on peut extraire l'une ou l'autre de ces deux clés 8 et 9. Cependant, lorsque l'une des clés est extraite, il est impossible d'extraire l'autre clé qui se trouve bloquée dans le bloc de sécurité qui la porte.It is therefore noted that when the two keys 8 and 9 are in their respective security blocks 2 and 3, one can extract one or the other of these two keys 8 and 9. However, when one of the keys is extracted , it is impossible to extract the other key which is blocked in the security block which carries it.

Une des applications du dispositif 1 représenté sur les figures consiste à réaliser une multiplicité des clés 8 qui sont chacune attribuée à une personne, chacune des clés 8 portant par exemple un code de référence de la personne à laquelle elle est attribuée et la clé 9 porte un trousseau de clés, par exemple par l'intermédiaire d'un anneau, chacune des clés de ce trousseau de clés permettant l'actionnement d'une multiplicité de serrures d'accès à des locaux, armoires ou autres.One of the applications of the device 1 represented in the figures consists in producing a multiplicity of keys 8 which are each assigned to a person, each of the keys 8 carrying for example a reference code of the person to whom it is assigned and the key 9 carries a set of keys, for example by means of a ring, each of the keys of this set of keys allowing the actuation of a multiplicity of locks for access to premises, cupboards or the like.

Si une des personnes a besoin d'utiliser le trousseau de clés porté par la clé 9 suspendue au dispositif 1, elle introduit sa clé 8 dans le bloc de sécurité 2 et elle peut extraire le clé 9 du dispositif 1, sa clé 8 restant bloquée dans le dispositif 1. Après qu'elle ait utilisée le trousseau de clés associé à la clé 9, elle introduit la clé 9 dans le dispositif 1 et elle peut extraire sa clé 8 du bloc de sécurité 2 et l'emporter, la clé 9 munie du trousseau se trouvant de nouveau bloquée dans le bloc de sécurité 3.If one of the people needs to use the keyring carried by the key 9 suspended from the device 1, he introduces his key 8 into the security block 2 and he can extract the key 9 from the device 1, his key 8 remaining blocked in the device 1. After having used the key ring associated with the key 9, she introduces the key 9 into the device 1 and she can extract her key 8 from the security block 2 and take it away, the key 9 fitted with the keychain which is again locked in the safety block 3.

Dans cette variante, on voit que l'ensemble des clés associé à la clé 9 peut rester à demeure sur le dispositif 1 tandis que chacune des personnes autorisée à utiliser le trousseau de clés associé à la clé 9 n'a besoin d'emporter avec soi qu'une seule clé 8.In this variant, it can be seen that all of the keys associated with the key 9 can remain permanently on the device 1 while each of the persons authorized to use the keyring associated with the key 9 does not need to carry with them. only one key 8.

Bien entendu, le dispositif 1 est fixé en un endroit déterminé par exemple uniquement accessible aux personnes munies d'une clé 8. Pour celà, le boîtier 10 peut présenter des pattes de fixation 19.Of course, the device 1 is fixed in a determined location, for example only accessible to persons provided with a key 8. For this, the housing 10 can have fixing lugs 19.

La présente invention ne se limite pas à l'exemple ci-dessus décrit. On aurait pu choisir des blocs de sécurité présentant des bras de levier décalés angulairement par rapport à la position des barillets permettant l'introduction ou l'extraction de la clé associée. De la sorte, la tige 18 peut être supprimée et chacun de ces bras de levier forme butée pour l'autre lorsqu'il se trouve dans ladite position. De plus, on aurait pu prévoir un boîtier dont la forme et la structure permettraient de maintenir et positionner les blocs de sécurité l'un par rapport à l'autre sans qu'il soit nécessaire de les assembler par l'élément 15. Bien d'autres variantes de réalisation sont possibles sans sortir du cadre défini par les revendications annexées.The present invention is not limited to the example described above. We could have chosen security blocks having lever arms angularly offset from the position of the barrels allowing the introduction or extraction of the associated key. In this way, the rod 18 can be eliminated and each of these lever arms forms a stop for the other when it is in said position. In addition, one could have provided a box whose shape and structure would maintain and position the safety blocks relative to each other without it being necessary to assemble them by element 15. Bien d other embodiments are possible without departing from the scope defined by the appended claims.
