  • temperatures comprised for example between -40 degrees Celsius and +50 degrees Celsius.
  • the document DE 199 64 314 A1 describes a system provided with a box housing a key that can move longitudinally in translation.
  • a two-lever release system and an automatic deployment system are arranged laterally on either side of the key.
  • the object of the present invention is therefore to propose a gripping system facilitating the detection or even the maneuvering of a key of small dimensions, especially in cold weather and with mittens or the like.
  • the invention thus relates to a gripping system for a key.
  • This gripping system comprises a hollow shell which extends in a transverse direction between two lateral sides open to an external environment, said shell extending longitudinally in a longitudinal direction from a rear side to a front side, the side front being open to the outside environment, the gripping system comprising two supports partially disposed in said shell, said two supports respectively comprising two recesses forming a variable-geometry reception space configured to contain said key at least partially, said two supports being each movable in rotation relative to said shell to move closer to each other until reaching a blocking position in which said key is blocked, at least in translation in the longitudinal direction, and to move apart one from the other until reaching a displacement position in which said key is movable in translation in said direction longitudinally in said reception space, each support emerging laterally from the shell via a said lateral side and having a support portion arranged outside of said shell.
  • a key can be inserted into the gripping system.
  • the two supports are movable in order to block the key at least in translation relative to the shell or to allow the key to be moved relative to the shell on request.
  • the two supports can jointly form a clamp gripping the key in the locking position.
  • An operator can grasp the shell and can exert a force on the two support portions with mittens or the like.
  • the two supports move apart at the front side of the hull by means of two rotary movements according to opposite directions.
  • the supports loosen the key which allows the key to partially come out of the gripping system. However, the key remains partially retained in the hull without human intervention.
  • the operator can then relax his effort to immobilize the key with respect to the shell using the supports in order to introduce it into a lock. This process is reversible.
  • the gripping system proves to be relatively simple and can be used in various climatic conditions, and in particular in the presence of temperatures comprised for example between -40 degrees Celsius and +50 degrees Celsius.
  • the gripping system actually has larger dimensions than the key. An operator can therefore more easily detect a key, and in particular a key inserted in a lock.
  • the gripping system can moreover have colors facilitating its visual detection. For example, the shell may be red in color.
  • the gripping system can be easily personalized.
  • the shell can be customizable.

  • the gripping system can in fact comprise at least one interface arranged on the shell and which can be requested by an individual to activate various functions.
  • an interface can be in communication by usual means with other components of the aircraft, and for example with an engine preheating system.
  • the gripping system can comprise a lamp.
  • the gripping system can comprise a radio-identification system, usually known by the acronym “RFID” and the English expression “radio frequency identification”.
  • the gripping system can be produced with qualified aeronautical materials, in particular within the framework of an aeronautical application.
  • the hull and the supports can in particular be obtained with a material that can withstand the environmental conditions experienced by an aircraft, in particular conditions of resistance to fuel, ozone, ultraviolet rays, de-icing fluids, etc.
  • each recess may comprise a front notch receiving a head of said key in said locking position when said key crosses said front side in a deployed position, each recess comprising a rear notch receiving said head of said key in said locking position when said key is in a retracted position.
  • the recesses thus make it possible to immobilize the key with respect to the shell when the key is in a retracted position or in an extended position. In the deployed position, the key can be inserted into a lock.
  • said rear notch can be arranged between the rear side of the hull and said front notch.
  • Each rear notch keeps the key retracted in the shell.
  • said front notch and said rear notch of the same recess can be delimited, in a single direction of the transverse direction, respectively by two arcuate edges.
  • the recesses can thus cooperate by shape interference with a key having a gripping head in the form of a ring extended by an actuating portion. Only the actuating portion is configured to be engaged in a lock.
  • each support may comprise a partition and a lateral flank delimiting the recess of this support respectively only in one direction of an elevation direction and in one direction of said transverse direction, said reception space s extending along said direction in elevation of the partition of one support as far as the partition of the other support, said reception space extending along said transverse direction between the lateral flank of a support and the lateral flank of the other support, said reception space emerging in the longitudinal direction on the open front side of the shell.
  • delimiting the recess means that the two supports participate jointly in the delimitation of the reception space. By moving away from or approaching each other, the two supports thus modify the geometry of the reception space to either confer freedom of movement in translation restricted to the key with respect to the shell, or block the key relative to the shell at least in translation.
  • the shell may comprise a first wall and a second wall arranged one above the other in an elevation direction, said shell comprising an elevation wall connecting, in the elevation direction, the first wall to the second wall, said supports being arranged partially between the first wall and the second wall.
  • the shell has a U-shape in section in a plane orthogonal to the transverse direction.
  • This U-shape allows the key to partially come out of the shell from the front side and allows the brackets to come out of the shell from the side sides.
  • the gripping system can comprise an elastic pusher configured to grip said key and to exert on said key a force tending to cause an actuation portion of the key to come out of the shell via said front side.
  • elastic pusher means that at least one member of the pusher is elastically deformable, for example to be able to be compressed, or even stretched, with respect to a position at rest. For example, the pusher is in its rest position when the key is in its deployed position.
  • the pusher thus has two functions. It allows the key to be pushed into its deployed position, while retaining it so that this key does not completely come out of the shell. The key is partially retained in the reception area by the pusher.
  • This pusher also has the function of authorizing the movement of the key to its retracted position. For example, a member of the pusher is compressed when the key is in its retracted position, then stretches to return to its rest position by pushing the key into its deployed position.
  • said pusher may comprise a hook configured to penetrate a head of said key, said pusher having a spring which extends in said longitudinal direction between a seat of the shell and said hook.
  • Such a seat can be formed by the raised wall described above.

Description

La présente invention concerne un système de préhension d'une clé.The present invention relates to a system for gripping a key.

Une porte peut comporter une serrure fonctionnant avec une clé. Par exemple, un aéronef et notamment un hélicoptère peut comprendre une porte munie d'une serrure à clé. Les clés utilisées sur les aéronefs sont parfois de petites tailles.A door may include a lock operating with a key. For example, an aircraft and in particular a helicopter can comprise a door provided with a key lock. Keys used on aircraft are sometimes small in size.

Or, un aéronef peut évoluer dans des environnements divers et peut être soumis à de fortes amplitudes thermiques. En particulier, un même hélicoptère peut évoluer dans une zone subissant des températures comprises par exemple entre -40 degrés Celsius et +50 degrés Celsius. Par temps froid, il peut alors être difficile de saisir une clé de petites dimensions, avec par exemple des moufles adaptées aux très basses températures, pour l'introduire dans une serrure ou pour la retirer d'une serrure.However, an aircraft can evolve in various environments and can be subjected to high thermal amplitudes. In particular, the same helicopter can evolve in an area undergoing temperatures comprised for example between -40 degrees Celsius and +50 degrees Celsius. In cold weather, it may then be difficult to grasp a key of small dimensions, for example with mittens adapted to very low temperatures, to introduce it into a lock or to remove it from a lock.

En outre, il peut être difficile de repérer une clé de petites tailles. Par exemple, dans des conditions climatiques extrêmes il peut être difficile de détecter qu'une clé de petites dimensions est toujours introduite dans une serrure avant le décollage.Also, it can be difficult to spot a key of small sizes. For example, in extreme climatic conditions it may be difficult to detect that a key of small dimensions is always inserted into a lock before takeoff.

Le document DE 199 64 314 A1 décrit un système muni d'un boîtier logeant une clé mobile longitudinalement en translation. Un système de libération à deux leviers et un système de déploiement automatique sont disposés latéralement de part et d'autre de la clé.The document DE 199 64 314 A1 describes a system provided with a box housing a key that can move longitudinally in translation. A two-lever release system and an automatic deployment system are arranged laterally on either side of the key.

Les documents US 6 314 775 B2 , US 2 500 198 A , et AU 16908 83 A sont aussi connus.The documents US 6,314,775 B2 , US 2,500,198A , and AU 16908 83 A are also known.

La présente invention a alors pour objet de proposer un système de préhension facilitant la détection voire la manœuvre d'une clé de petites dimensions, notamment par temps froid et avec des moufles ou équivalents.The object of the present invention is therefore to propose a gripping system facilitating the detection or even the maneuvering of a key of small dimensions, especially in cold weather and with mittens or the like.

L'invention vise ainsi un système de préhension pour clé. Ce système de préhension comporte une coque creuse qui s'étend selon une direction transversale entre deux cotés latéraux ouverts sur un milieu extérieur, ladite coque s'étendant longitudinalement selon une direction longitudinale d'un côté arrière jusqu'à un côté avant, le côté avant étant ouvert sur le milieu extérieur, le système de préhension comprenant deux supports disposés partiellement dans ladite coque, lesdits deux supports comprenant respectivement deux renfoncements formant un espace d'accueil à géométrie variable configuré pour contenir ladite clé au moins partiellement, lesdits deux supports étant chacun mobiles en rotation par rapport à ladite coque pour se rapprocher l'un de l'autre jusqu'à atteindre une position de blocage dans laquelle ladite clé est bloquée, au moins en translation selon la direction longitudinale, et pour s'écarter l'un de l'autre jusqu'à atteindre une position de déplacement dans laquelle ladite clé est mobile en translation selon ladite direction longitudinale dans ledit espace d'accueil, chaque support sortant latéralement de la coque par un dit côté latéral et présentant une portion d'appui agencée en dehors de ladite coque.The invention thus relates to a gripping system for a key. This gripping system comprises a hollow shell which extends in a transverse direction between two lateral sides open to an external environment, said shell extending longitudinally in a longitudinal direction from a rear side to a front side, the side front being open to the outside environment, the gripping system comprising two supports partially disposed in said shell, said two supports respectively comprising two recesses forming a variable-geometry reception space configured to contain said key at least partially, said two supports being each movable in rotation relative to said shell to move closer to each other until reaching a blocking position in which said key is blocked, at least in translation in the longitudinal direction, and to move apart one from the other until reaching a displacement position in which said key is movable in translation in said direction longitudinally in said reception space, each support emerging laterally from the shell via a said lateral side and having a support portion arranged outside of said shell.

Dès lors, une clé peut être insérée dans le système de préhension. Les deux supports sont mobiles afin de bloquer la clé au moins en translation par rapport à la coque ou pour permettre à la clé d'être déplacée par rapport à la coque sur requête. Les deux supports peuvent former conjointement une pince serrant la clé dans la position de blocage. Un opérateur peut saisir la coque et peut exercer un effort sur les deux portions d'appui avec des moufles ou équivalent. Les deux supports s'écartent au niveau du côté avant de la coque par le biais de deux mouvements rotatifs selon des sens opposés. Les supports desserrent la clé ce qui permet de faire sortir partiellement la clé du système de préhension. La clé reste toutefois retenue partiellement dans la coque sans intervention humaine. L'opérateur peut alors relâcher son effort pour immobiliser la clé par rapport à la coque à l'aide des supports afin de l'introduire dans une serrure. Ce procédé est réversible.From then on, a key can be inserted into the gripping system. The two supports are movable in order to block the key at least in translation relative to the shell or to allow the key to be moved relative to the shell on request. The two supports can jointly form a clamp gripping the key in the locking position. An operator can grasp the shell and can exert a force on the two support portions with mittens or the like. The two supports move apart at the front side of the hull by means of two rotary movements according to opposite directions. The supports loosen the key which allows the key to partially come out of the gripping system. However, the key remains partially retained in the hull without human intervention. The operator can then relax his effort to immobilize the key with respect to the shell using the supports in order to introduce it into a lock. This process is reversible.

Selon un autre aspect, le système de préhension s'avère relativement simple et peut être utilisé dans des conditions climatiques diverses, et notamment en présence de températures comprises par exemple entre -40 degrés Celsius et +50 degrés Celsius.According to another aspect, the gripping system proves to be relatively simple and can be used in various climatic conditions, and in particular in the presence of temperatures comprised for example between -40 degrees Celsius and +50 degrees Celsius.

En outre, le système de préhension présente de fait des dimensions plus importantes que la clé. Un opérateur peut donc détecter plus facilement une clé, et notamment une clé insérée dans une serrure. Le système de préhension peut d'ailleurs présenter des couleurs facilitant sa détection visuelle. Par exemple, la coque peut être de couleur rouge.In addition, the gripping system actually has larger dimensions than the key. An operator can therefore more easily detect a key, and in particular a key inserted in a lock. The gripping system can moreover have colors facilitating its visual detection. For example, the shell may be red in color.

Selon un autre aspect, le système de préhension peut être aisément personnalisé. Par exemple, la coque peut être personnalisable.According to another aspect, the gripping system can be easily personalized. For example, the shell can be customizable.

Le système de préhension peut comprendre une ou plusieurs des caractéristiques qui suivent.The gripping system may include one or more of the following features.

Ainsi, le système de préhension peut remplir d'autres fonctions. Le système de préhension peut en effet comprendre au moins une interface agencée sur la coque et pouvant être sollicitée par un individu pour activer des fonctions diverses. Par exemple, une interface peut être en communication par des moyens usuels avec d'autres organes de l'aéronef, et par exemple avec un système de préchauffage d'un moteur.Thus, the gripping system can perform other functions. The gripping system can in fact comprise at least one interface arranged on the shell and which can be requested by an individual to activate various functions. For example, an interface can be in communication by usual means with other components of the aircraft, and for example with an engine preheating system.

Selon une possibilité, le système de préhension peut comprendre une lampe.According to one possibility, the gripping system can comprise a lamp.

Selon une autre possibilité compatible avec les précédentes, le système de préhension peut comprendre un système de radioidentification, usuellement connu sous l'acronyme « RFID » et l'expression anglaise « radio frequency identification ».According to another possibility compatible with the previous ones, the gripping system can comprise a radio-identification system, usually known by the acronym “RFID” and the English expression “radio frequency identification”.

Selon une autre possibilité compatible avec les précédentes, le système de préhension peut être réalisé avec des matériaux qualifiés aéronautiques, notamment dans le cadre d'une application aéronautique.According to another possibility compatible with the previous ones, the gripping system can be produced with qualified aeronautical materials, in particular within the framework of an aeronautical application.

La coque et les supports peuvent notamment être obtenus avec un matériau pouvant supporter les conditions environnementales subies par un aéronef, en particulier des conditions de résistance au carburant, à l'ozone, aux ultraviolets, à des fluides de dégivrage...The hull and the supports can in particular be obtained with a material that can withstand the environmental conditions experienced by an aircraft, in particular conditions of resistance to fuel, ozone, ultraviolet rays, de-icing fluids, etc.

Selon une autre possibilité compatible avec les précédentes, chaque renfoncement peut comporter une encoche avant accueillant une tête de ladite clé dans ladite position de blocage lorsque ladite clé traverse ledit côté avant dans une position déployée, chaque renfoncement comportant une encoche arrière accueillant ladite tête de ladite clé dans ladite position de blocage lorsque ladite clé est dans une position rétractée.According to another possibility compatible with the previous ones, each recess may comprise a front notch receiving a head of said key in said locking position when said key crosses said front side in a deployed position, each recess comprising a rear notch receiving said head of said key in said locking position when said key is in a retracted position.

Les renfoncements permettent ainsi d'immobiliser la clé par rapport à la coque lorsque la clé est dans une position rétractée ou dans une position déployée. Dans la position déployée, la clé peut être introduite dans une serrure.The recesses thus make it possible to immobilize the key with respect to the shell when the key is in a retracted position or in an extended position. In the deployed position, the key can be inserted into a lock.

Selon une possibilité compatible avec les précédentes, ladite encoche arrière peut être agencée entre le côté arrière de la coque et ladite encoche avant.According to a possibility compatible with the previous ones, said rear notch can be arranged between the rear side of the hull and said front notch.

Chaque encoche arrière permet de maintenir la clé rétractée dans la coque.Each rear notch keeps the key retracted in the shell.

Selon une possibilité compatible avec les précédentes, ladite encoche avant et ladite encoche arrière d'un même renfoncement peuvent être délimitées, selon un unique sens de la direction transversale, respectivement par deux bords en arc de cercle.According to a possibility compatible with the previous ones, said front notch and said rear notch of the same recess can be delimited, in a single direction of the transverse direction, respectively by two arcuate edges.

Les renfoncements peuvent ainsi coopérer par interférence de forme avec une clé ayant une tête de préhension en forme d'anneau prolongée par une portion d'actionnement. Seule la portion d'actionnement est configurée pour être engagée dans une serrure.The recesses can thus cooperate by shape interference with a key having a gripping head in the form of a ring extended by an actuating portion. Only the actuating portion is configured to be engaged in a lock.

Selon une possibilité compatible avec les précédentes, chaque support peut comporter une cloison et un flanc latéral délimitant le renfoncement de ce support respectivement uniquement selon un sens d'une direction en élévation et selon un sens de ladite direction transversale, ledit espace d'accueil s'étendant selon ladite direction en élévation de la cloison d'un support jusqu'à la cloison de l'autre support, ledit espace d'accueil s'étendant selon ladite direction transversale entre le flanc latéral d'un support et le flanc latéral de l'autre support, ledit espace d'accueil débouchant selon la direction longitudinale sur le côté avant ouvert de la coque.According to a possibility compatible with the previous ones, each support may comprise a partition and a lateral flank delimiting the recess of this support respectively only in one direction of an elevation direction and in one direction of said transverse direction, said reception space s extending along said direction in elevation of the partition of one support as far as the partition of the other support, said reception space extending along said transverse direction between the lateral flank of a support and the lateral flank of the other support, said reception space emerging in the longitudinal direction on the open front side of the shell.

L'expression « délimitant le renfoncement » signifie que les deux supports participent conjointement à la délimitation de l'espace d'accueil. En s'écartant ou en se rapprochant l'un de l'autre, les deux supports modifient ainsi la géométrie de l'espace d'accueil pour soit conférer une liberté de mouvement en translation restreinte à la clé par rapport à la coque, soit bloquer la clé par rapport à la coque au moins en translation.The expression "delimiting the recess" means that the two supports participate jointly in the delimitation of the reception space. By moving away from or approaching each other, the two supports thus modify the geometry of the reception space to either confer freedom of movement in translation restricted to the key with respect to the shell, or block the key relative to the shell at least in translation.

Selon une possibilité compatible avec les précédentes, la coque peut comporter une première paroi et une deuxième paroi disposées l'une au dessus de l'autre selon une direction en élévation, ladite coque comprenant une paroi en élévation reliant selon la direction en élévation la première paroi à la deuxième paroi, lesdits supports étant disposés partiellement entre la première paroi et la deuxième paroi.According to a possibility compatible with the previous ones, the shell may comprise a first wall and a second wall arranged one above the other in an elevation direction, said shell comprising an elevation wall connecting, in the elevation direction, the first wall to the second wall, said supports being arranged partially between the first wall and the second wall.

Par exemple, la coque a une forme de U en coupe dans un plan orthogonal à la direction transversale. Cette forme en U permet à la clé de sortir partiellement de la coque par le coté avant et permet aux supports de sortir de la coque par les côtés latéraux.For example, the shell has a U-shape in section in a plane orthogonal to the transverse direction. This U-shape allows the key to partially come out of the shell from the front side and allows the brackets to come out of the shell from the side sides.

Selon une possibilité compatible avec les précédentes, le système de préhension peut comprendre un pousseur élastique configuré pour saisir ladite clé et pour exercer sur ladite clé un effort tendant à faire sortir de la coque une portion d'actionnement de la clé par ledit côté avant.According to a possibility compatible with the previous ones, the gripping system can comprise an elastic pusher configured to grip said key and to exert on said key a force tending to cause an actuation portion of the key to come out of the shell via said front side.

L'expression « pousseur élastique » signifie qu'au moins un organe du pousseur est déformable élastiquement, par exemple pour pouvoir être comprimé, voire étiré, au regard d'une position au repos. Par exemple, le pousseur est dans sa position de repos lorsque la clé est dans sa position déployée.The expression "elastic pusher" means that at least one member of the pusher is elastically deformable, for example to be able to be compressed, or even stretched, with respect to a position at rest. For example, the pusher is in its rest position when the key is in its deployed position.

Le pousseur a ainsi deux fonctions. Il permet de pousser la clé dans sa position déployée, tout en la retenant pour que cette clé ne sorte pas entièrement de la coque. La clé est retenue en partie dans l'espace d'accueil par le pousseur. Ce pousseur a aussi pour fonction d'autoriser le déplacement de la clé vers sa position rétractée. Par exemple, un organe du pousseur est comprimé lorsque la clé est dans sa position rétractée, puis s'étire pour retourner dans sa position de repos en poussant la clé dans sa position déployée.The pusher thus has two functions. It allows the key to be pushed into its deployed position, while retaining it so that this key does not completely come out of the shell. The key is partially retained in the reception area by the pusher. This pusher also has the function of authorizing the movement of the key to its retracted position. For example, a member of the pusher is compressed when the key is in its retracted position, then stretches to return to its rest position by pushing the key into its deployed position.

Par exemple, ledit pousseur peut comporter un crochet configuré pour pénétrer dans une tête de ladite clé, ledit pousseur ayant un ressort qui s'étend selon ladite direction longitudinale entre un siège de la coque et ledit crochet.For example, said pusher may comprise a hook configured to penetrate a head of said key, said pusher having a spring which extends in said longitudinal direction between a seat of the shell and said hook.

Un tel siège peut être formé par la paroi en élévation décrite précédemment.Such a seat can be formed by the raised wall described above.

Selon un exemple compatible avec le précédent, le pousseur peut ainsi tendre à immobiliser la clé en rotation par interférence de forme avec la tête de la clé. Le pousseur et les encoches peuvent ainsi conjointement immobiliser la clé par rapport à la coque.According to an example compatible with the previous one, the pusher can thus tend to immobilize the key in rotation by shape interference with the head of the key. The pusher and the notches can thus jointly immobilize the key with respect to the shell.

Par exemple, ledit crochet peut comporter un doigt configuré pour pénétrer dans ladite tête et une face de retenue, ladite face de retenue décrivant un arc d'un cercle centré sur un premier axe, le premier axe étant configuré pour être décalé par rapport à un deuxième axe sur lequel est centré un arc d'un cercle suivi par un bord de ladite tête.For example, said hook may comprise a finger configured to penetrate into said head and a retaining face, said retaining face describing an arc of a circle centered on a first axis, the first axis being configured to be offset with respect to a second axis on which is centered an arc of a circle followed by an edge of said head.

Le bord de la clé est alors accolé à la face de retenue.The edge of the key is then attached to the retaining face.

Selon un exemple compatible avec les précédents, ledit crochet peut comporter un canal de guidage, ledit ressort s'étendant dans ledit canal de guidage.According to an example compatible with the previous ones, said hook may include a guide channel, said spring extending in said guide channel.

Selon une possibilité compatible avec les précédentes, lesdits deux supports peuvent être mobiles en rotation par rapport à la coque autour d'un même axe géométrique de rotation.According to a possibility compatible with the previous ones, said two supports can be rotatable relative to the shell around the same geometric axis of rotation.

Selon une possibilité compatible avec les précédentes, au moins un desdits supports peut comporter un pion qui est agencé dans un logement de ladite coque et est mobile en rotation dans ledit logement ou au moins un desdits supports peut comporter un logement mobile en rotation autour d'un pion de ladite coque.According to a possibility compatible with the previous ones, at least one of said supports may comprise a pin which is arranged in a housing of said shell and is rotatable in said housing or at least one of said supports may comprise a housing mobile in rotation around a pawn of said hull.

Ainsi, chaque support est facilement rendu mobile en rotation par rapport à la coque.Thus, each support is easily made mobile in rotation relative to the shell.

Selon une possibilité compatible avec les précédentes, au moins un desdits supports peut comporter une butée qui est mobile dans une gorge de ladite coque entre deux flancs de la gorge ou au moins un desdits supports peut comporter une gorge dans laquelle une butée de ladite coque est mobile.According to a possibility compatible with the previous ones, at least one of said supports can include a stop which is movable in a groove of said shell between two sides of the groove or at least one of said supports can include a groove in which a stop of said shell is mobile.

Ainsi, chaque support est mobile en rotation par rapport à la coque dans les limites imposées par une gorge et une butée.Thus, each support is rotatable relative to the shell within the limits imposed by a groove and an abutment.

Selon une possibilité complémentaire ou alternative, chaque support peut comporter un pied venant en butée contre une face d'arrêt d'une portion en élévation de la coque dans la position de déplacement.According to a complementary or alternative possibility, each support can comprise a foot coming into abutment against a stop face of an elevated portion of the shell in the displacement position.

Selon une possibilité compatible avec les précédentes, ladite portion d'appui d'un dit support peut être disposée selon ladite direction longitudinale entre ledit côté arrière et un axe géométrique de rotation de ce support.According to a possibility compatible with the previous ones, said support portion of a said support can be arranged in said longitudinal direction between said rear side and a geometric axis of rotation of this support.

Pour atteindre la position de déplacement, les extrémités des supports situées au niveau du côté avant s'éloignent afin de libérer la clé alors que les extrémités des supports situées au niveau du côté arrière se rapprochent.To reach the displacement position, the ends of the supports located at the level of the front side move away in order to release the key while the ends of the supports located at the level of the rear side approach each other.

Selon une possibilité compatible avec les précédentes, ledit système de préhension peut comporter un système de rappel pour placer lesdits deux supports dans la position de blocage en l'absence d'un effort exercé sur les supports par un opérateur supérieur à un seuil d'effort.According to a possibility compatible with the previous ones, said gripping system may comprise a return system for placing said two supports in the locking position in the absence of a force exerted on the supports by an operator greater than a force threshold .

Par exemple, un tel système de rappel est un système magnétique comprenant un ou plusieurs aimants permanents.For example, such a return system is a magnetic system comprising one or more permanent magnets.

Par exemple, le système de rappel comporte un sous-ensemble dénommé par commodité « rappel de fermeture » et/ou un sous ensemble dénommé par commodité « rappel au repos » par support configurés pour maintenir ce support dans la position de blocage jusqu'à un seuil d'effort exercé sur ce support.For example, the return system comprises a sub-assembly called for convenience “closing reminder” and/or a sub-assembly called for convenience “rest reminder” per support configured to maintain this support in the blocking position until a force threshold exerted on this support.

Par exemple, le système de rappel comporte deux rappels de fermeture magnétiques respectivement pour les deux supports, chaque rappel de fermeture d'un dit support comportant un premier organe de fermeture fixé à ce support et un deuxième organe de fermeture fixé à une paroi de la coque accolée à ce support, au moins un des premier organe de fermeture et deuxième organe de fermeture comprenant un aimant permanent de fermeture.For example, the reminder system comprises two magnetic closure reminders respectively for the two supports, each closure reminder of a said support comprising a first closure member fixed to this support and a second closure member fixed to a wall of the shell attached to this support, at least one of the first closing member and second closing member comprising a permanent closing magnet.

Par exemple, le système de rappel comporte deux rappels au repos magnétiques respectivement pour les deux supports, chaque rappel au repos d'un support comportant un premier organe de rappel fixé à ce support et un deuxième organe de rappel fixé à une paroi de la coque séparée en élévation de ce support par l'autre support, au moins un des premier organe de rappel et deuxième organe de rappel comprenant un aimant permanent de verrouillage.For example, the return system comprises two magnetic rest reminders respectively for the two supports, each rest reminder of a support comprising a first return member fixed to this support and a second return member fixed to a wall of the shell separated in elevation from this support by the other support, at least one of the first return member and second return member comprising a permanent locking magnet.

Ainsi, un ou plusieurs systèmes magnétiques peuvent tendre à maintenir les deux supports dans la position de blocage. Un opérateur doit alors exercer un effort sur les portions d'appui pour atteindre la position de déplacement.Thus, one or more magnetic systems can tend to maintain the two supports in the locking position. An operator must then exert a force on the support portions to reach the displacement position.

Les éléments présents dans plusieurs figures distinctes sont affectés d'une seule et même référence.The elements present in several separate figures are assigned a single reference.

Trois directions X, Y et Z orthogonales les unes par rapport aux autres sont représentées sur certaines figures.Three directions X, Y and Z orthogonal to each other are shown in some figures.

La direction X est dite longitudinale. L'expression « direction longitudinale » désigne une direction parallèle à la direction X.The X direction is said to be longitudinal. The expression "longitudinal direction" designates a direction parallel to the X direction.

Une autre direction Y est dite transversale. L'expression « direction transversale » désigne une direction parallèle à la direction Y.Another direction Y is called transverse. The expression "transverse direction" designates a direction parallel to the Y direction.

Enfin, une troisième direction Z est dite en élévation. L'expression « direction en élévation » désigne une direction parallèle à la direction Z.Finally, a third direction Z is said to be in elevation. The term "elevation direction" means a direction parallel to the Z direction.

La figure 1 illustre un système de préhension 1 pour manœuvrer une clé, par exemple pour porter une clé ouvrant une porte d'un véhicule et éventuellement d'un aéronef. Le système de préhension 1 comporte une coque 5 creuse. De plus, le système de préhension 1 comporte deux supports 20, 50 disposés partiellement dans la coque 5, ces supports 20, 50 débordant toutefois en dehors de la coque 5 au moins latéralement voire vers l'avant.The figure 1 illustrates a gripping system 1 for maneuvering a key, for example for carrying a key opening a door of a vehicle and possibly of an aircraft. The gripping system 1 comprises a hollow shell 5. In addition, the gripping system 1 comprises two supports 20, 50 arranged partially in the shell 5, these supports 20, 50 however projecting outside the shell 5 at least laterally or even forwards.

Les deux supports 20, 50 comprennent respectivement deux renfoncements, illustrés par la suite, qui délimitent au sein de la coque 5 un espace d'accueil configuré pour contenir une clé. Les deux supports 20, 50 sont tous deux mobiles en rotation par rapport à la coque 5, par exemple autour d'un même axe géométrique de rotation AX, pour modifier la géométrie de l'espace d'accueil. Dans la position de blocage POS1 illustrée dans la figure 1, les deux supports 20, 50 bloquent conjointement la clé en translation dans la coque 5. Dans une position de déplacement illustrée par la suite, les deux supports 20, 50 octroient une liberté de mouvement en translation à la clé par rapport à la coque 5.The two supports 20, 50 respectively comprise two recesses, illustrated below, which delimit within the shell 5 a reception space configured to contain a key. The two supports 20, 50 are both rotatable relative to the shell 5, for example around the same geometric axis of rotation AX, to modify the geometry of the reception space. In the blocking position POS1 illustrated in the figure 1 , the two supports 20, 50 jointly block the key in translation in the shell 5. In a displacement position illustrated below, the two supports 20, 50 grant freedom of movement in translation to the key relative to the shell 5 .

Par ailleurs, chaque support 20, 50 présente une portion d'appui 21, 51 agencée en dehors de la coque 5. Un opérateur peut alors appuyer sur les portions d'appui 21, 51 pour déplacer les deux supports 20, 50. Selon un autre aspect, les portions d'appui 21, 51 des supports 20, 50 peuvent être disposées selon ladite direction longitudinale entre un côté arrière CARR de la coque 5 et l'axe géométrique de rotation AX.Furthermore, each support 20, 50 has a support portion 21, 51 arranged outside the shell 5. An operator can then press on the support portions 21, 51 to move the two supports 20, 50. According to a Another aspect, the support portions 21, 51 of the supports 20, 50 can be arranged in said longitudinal direction between a rear side CARR of the shell 5 and the geometric axis of rotation AX.

En référence à la figure 2, la coque 5 s'étend selon la direction transversale Y entre deux cotés latéraux CLAT1, CLAT2 qui débouchent sur un milieu extérieur EXT, à savoir un milieu situé à l'extérieur du système de préhension 1. De plus, la coque 5 s'étend en élévation entre une première paroi 6 et une deuxième paroi 7. La première paroi 6 est située au dessus de la deuxième paroi 7 selon un sens vers le haut Z1 de la direction en élévation Z. A l'inverse, la deuxième paroi 7 est située en dessous de la première paroi 6 selon un sens vers le bas Z2 de la direction en élévation Z. En outre, la coque 5 s'étend longitudinalement selon une direction longitudinale X du côté arrière CARR jusqu'à un côté avant CAV. Le côté avant CAV peut déboucher sur le milieu extérieur EXT. En outre, la coque 5 comporte une paroi en élévation 8 reliant la première paroi 6 à la deuxième paroi 7. Par exemple, la paroi en élévation 8 peut obturer le côté arrière CARR, ce côté arrière CARR ne débouchant alors pas sur le milieu extérieur EXT.With reference to the figure 2 , the shell 5 extends in the transverse direction Y between two lateral sides CLAT1, CLAT2 which lead to an external environment EXT, namely a medium situated outside the gripping system 1. In addition, the shell 5 is extends in elevation between a first wall 6 and a second wall 7. The first wall 6 is located above the second wall 7 in an upward direction Z1 of the direction in elevation Z. Conversely, the second wall 7 is located below the first wall 6 in a downward direction Z2 of the elevation direction Z. In addition, the shell 5 extends longitudinally in a longitudinal direction X from the rear side CARR to a front side CAV. The front side CAV can lead to the external environment EXT. In addition, the shell 5 comprises an elevation wall 8 connecting the first wall 6 to the second wall 7. For example, the elevation wall 8 can block the rear side CARR, this rear side CARR then not leading to the external environment. EXT.

La première paroi 6, la deuxième paroi 7, voire la paroi en élévation 8, délimitent conjointement un espace interne de la coque 5. Cet espace interne est ouvert latéralement et au moins par le côté avant sur le milieu extérieur.The first wall 6, the second wall 7, or even the wall in elevation 8, jointly delimit an internal space of the shell 5. This internal space is open laterally and at least via the front side to the external environment.

Selon un autre aspect, la première paroi 6, la deuxième paroi 7, voire la paroi en élévation 8, forment une coque monolithique, ou peuvent comprendre plusieurs pièces distinctes fixées les unes aux autres de manière usuelle.According to another aspect, the first wall 6, the second wall 7, or even the wall in elevation 8, form a monolithic shell, or may comprise several distinct parts fixed to each other in the usual way.

Indépendamment de ces caractéristiques et en référence à la figure 3, au moins la première paroi 6 ou la deuxième paroi 7 peut comprendre un logement 17, 170 et une gorge 18, 180, la gorge 18, 180 s'étendant selon un arc de cercle entre deux flancs 181-182, 1810-1820. Par exemple, la première paroi 6 et/ou la deuxième paroi 7 comportent un orifice circulaire 16, 160 prolongé axialement en son centre par un logement 17, 170 cylindrique et radialement par la gorge 18, 180. Ainsi la première paroi 6 peut comprendre un premier logement 17, un premier orifice circulaire 16 et une première gorge 18, et /ou la deuxième paroi 7 peut comprendre un deuxième logement 170, un deuxième orifice circulaire 160 et une deuxième gorge 180.Independently of these characteristics and with reference to the picture 3 , at least the first wall 6 or the second wall 7 may comprise a housing 17, 170 and a groove 18, 180, the groove 18, 180 extending along an arc of a circle between two sides 181-182, 1810-1820. For example, the first wall 6 and/or the second wall 7 comprise a circular orifice 16, 160 extended axially at its center by a cylindrical housing 17, 170 and radially by the groove 18, 180. Thus the first wall 6 can comprise a first housing 17, a first circular orifice 16 and a first groove 18, and/or the second wall 7 may comprise a second housing 170, a second circular orifice 160 and a second groove 180.

Selon la figure 11, un opérateur saisit le système de préhension 1, si nécessaire avec des moufles. L'opérateur appuie alors sur les portions d'appui 21, 51. Il en résulte des rotations ROT1, ROT2 autour de l'axe géométrique de rotation AX dans des sens opposés des deux supports 20, 50. Les deux supports 20, 50 atteignent la position de déplacement POS2. Eventuellement, un pied 200, 500 de chaque support 20, 50 entre en butée contre un organe d'arrêt 800 de la portion en élévation 8 de la coque 5. Eventuellement, les butées des supports 20, 50 ou des parois 6,7 de la coque 5 sont en appui contre un flanc d'une gorge respectivement des parois 6,7 ou des supports 20, 50.According to figure 11 , an operator grasps the gripping system 1, if necessary with mittens. The operator then presses on the support portions 21, 51. This results in rotations ROT1, ROT2 around the geometric axis of rotation AX in opposite directions of the two supports 20, 50. The two supports 20, 50 reach travel position POS2. Optionally, a foot 200, 500 of each support 20, 50 comes into abutment against a stop member 800 of the elevated portion 8 of the shell 5. Optionally, the stops of the supports 20, 50 or of the walls 6.7 of the shell 5 bears against a side of a groove respectively walls 6.7 or supports 20, 50.

En référence à la figure 12, le ressort 79 du pousseur 75 peut alors s'étendre selon la flèche F1 et positionner la clé 90 dans sa position déployée POS4.With reference to the figure 12 , the spring 79 of the pusher 75 can then extend along the arrow F1 and position the key 90 in its deployed position POS4.

En référence à la figure 13, l'opérateur relâche alors les portions d'appui 21, 51. Les rappels de fermeture et de verrouillage éventuels rappellent le cas échéant les supports 20, 50 dans la position de blocage POS1. La tête de la clé 90 se trouve alors agencée dans les encoches avant 29, 59, la portion d'actionnement 93 s'étendant en dehors de la coque 5.With reference to the figure 13 , the operator then releases the support portions 21, 51. Any closing and locking reminders remind the supports 20, 50 in the locking position POS1, if necessary. The head of the key 90 is then arranged in the front notches 29, 59, the actuating portion 93 extending outside the shell 5.

Naturellement, la présente invention est sujette à de nombreuses variations quant à sa mise en œuvre.
