Definitions

  • the present invention relates to the field of acoustic enclosures.
  • It relates more particularly to an acoustic enclosure frame comprising a device for connection to another acoustic enclosure.
  • the loudspeakers are generally arranged in a particular way so as to obtain a given acoustic result.
  • a highly sought-after acoustic objective is in particular to optimize the ratio between the sound level and the desired coverage area.
  • the acoustic enclosures are sometimes assembled together, in particular in a column (or “line arrays”), thanks to connection devices present on each enclosure.
  • These assemblies may consist of several enclosures, each capable of weighing more than 50 kilograms. The enclosures are then either placed in suspension in the air by means of attachment means or placed on the ground.
  • the frame of each enclosure generally includes a connection device allowing it to be hooked to another enclosure.
  • connection device comprises a locking system and an eyelet.
  • the locking system described in this document is a "T" assembly housed under the enclosure and comprising a mechanism for causing the movement of a lock.
  • the locking system is configured to assume a locked configuration in which a lock of the first enclosure is seated in an eyelet of the second enclosure and an unlocked configuration or army in which the lock of the first enclosure is removed from the eyelet of the second enclosure.
  • a locking system comprising a slide, such as that proposed by document US8130996 , can be considered.
  • the object of the present invention is to resolve at least one of the aforementioned drawbacks, which may also lead to other advantages.
  • the acoustic enclosure frame thus configured and comprising such a connection device allows automatic assembly of the speakers. having the advantage of being simple and more reliable. Locking and arming of the locking system can be done by a single operator. When approaching a speaker with an armed configuration locking system to another speaker, the two speakers automatically lock together.
  • the guide elements of the slide by sliding against the edges of the legs, allow good guidance of the slide between the legs.
  • the translational movement of the slide is thus fluid.
  • the fluidity of the sliding of the slide is improved by the presence of the spacer connecting the legs and making it possible to keep the legs parallel in them, with a better constancy of their distance from one another.
  • the assembly and arming of the enclosures is facilitated because at least part of the movements of the various elements making up the connection device is automated.
  • the use of the first elastic member connected to the slide makes it possible to automate the translational movement of the slide from the high position to the low position.
  • the use of the second elastic member connected to the selection screw makes it possible to automate the displacement of the selection screw from the separated position to the returned position.
  • the locking rod ensures proper locking of the locking system and thus a secure assembly of the two enclosures.
  • the locking element comprises a collar integral with the locking rod, the collar being formed around the locking rod and having an outer diameter greater than a diameter of the lower orifice of the front tab.
  • the collar also constitutes a means of securing. Since the flange has an outside diameter greater than a diameter of the lower hole in the front leg, the flange prevents the locking rod from possibly passing past the legs.
  • the locking system comprises a connecting lug fixed on the one hand to the locking element and on the other hand to the selection screw, and the locking element is crimped on the connecting lug.
  • the crimping of the locking element on the connecting tab constitutes an additional means of securing the assembly between the locking element and the tabs. In addition, this makes it possible to better ensure squareness between the locking element and the connecting tab.
  • the actuator comprises a part overmolded on at least part of the locking element.
  • the locking system comprises two spacers connecting the two legs to one another, the two spacers being arranged on either side of the legs.
  • the legs each have two upper holes
  • the locking system comprising two selection screws, the rods of the two selection screws passing through the upper holes of the two legs.
  • the opening of the slide has at least two wide portions and at least two narrow portions. The wide sections of the two selector screws are in the opening of the slider in the retracted position and the narrow sections of the two selector screws are in the opening in the spread position.
  • the slide is provided with two pairs of guide elements, each pair of guide elements resting on an edge of at least one of the two tabs, on either side of the paw.
  • the locking system switches from the armed configuration to the forced open configuration by moving the slide from the lower position to the upper position. And the locking system changes from the locked configuration to the forced open configuration by moving the actuator from the pushed position to the pulled position and the slide from the high position to the upper position.
  • the forced open configuration can be used when disconnecting two enclosures initially assembled together.
  • the forced open configuration thus makes it possible to prevent the speakers from remaining hooked together after unlocking or disconnection.
  • the slide can take the high position, the upper position and the lower position.
  • the high position being a position between the upper position and the lower position.
  • the frame comprises two connection devices configured to be placed on either side of the enclosure.
  • the invention also relates to an acoustic enclosure comprising an armature having at least part of the preceding characteristics.
  • the invention also relates to an assembly of at least two acoustic enclosures comprising a first acoustic enclosure and a second acoustic enclosure each comprising an armature having at least part of the preceding characteristics.
  • the eyelet of the second enclosure is locked in the locking system of the first enclosure when the first and second enclosures are assembled together.

Description

La présente invention concerne le domaine des enceintes acoustiques.The present invention relates to the field of acoustic enclosures.

Elle concerne plus particulièrement une armature d'enceinte acoustique comprenant un dispositif de connexion à une autre enceinte acoustique.It relates more particularly to an acoustic enclosure frame comprising a device for connection to another acoustic enclosure.

Elle concerne également une enceinte acoustique comportant une telle armature.It also relates to an acoustic enclosure comprising such a frame.

Enfin, elle concerne deux enceintes acoustiques comportant chacune une telle armature et accrochées entre elles au moyen de leur armature.Finally, it relates to two acoustic enclosures each comprising such a frame and hooked together by means of their frame.

Dans des grandes salles telles que les salles de théâtre, de concert ou conférence, les enceintes acoustiques sont généralement disposées de manière particulière de sorte à obtenir un résultat acoustique donné. Un objectif acoustique très recherché est notamment d'optimiser le ratio entre le niveau sonore et la zone de couverture souhaitée.In large rooms such as theaters, concert halls or conference halls, the loudspeakers are generally arranged in a particular way so as to obtain a given acoustic result. A highly sought-after acoustic objective is in particular to optimize the ratio between the sound level and the desired coverage area.

A cet effet, les enceintes acoustiques sont parfois assemblées entre elles, notamment en colonne (ou « line arrays »), grâce à des dispositifs de connexion présents sur chaque enceinte. Ces assemblages peuvent être constitués de plusieurs enceintes, pouvant peser chacune plus de 50 kilogrammes. Les enceintes sont ensuite soit disposées en suspension dans l'air grâce à des moyens d'accrochage soit placées sur le sol.To this end, the acoustic enclosures are sometimes assembled together, in particular in a column (or “line arrays”), thanks to connection devices present on each enclosure. These assemblies may consist of several enclosures, each capable of weighing more than 50 kilograms. The enclosures are then either placed in suspension in the air by means of attachment means or placed on the ground.

La plupart des enceintes destinées à être assemblées comportent une armature permettant de soutenir et de maintenir les différentes parties de l'enceinte. L'armature de chaque enceinte comporte généralement un dispositif de connexion permettant de l'accrocher à une autre enceinte.Most enclosures intended to be assembled have a frame to support and hold the various parts of the enclosure. The frame of each enclosure generally includes a connection device allowing it to be hooked to another enclosure.

A cet égard, on connait par exemple le document EP 2 640 087 qui divulgue une enceinte acoustique comportant un dispositif de connexion à une autre enceinte acoustique. Le dispositif de connexion comporte un système de verrouillage et un œillet. Le système de verrouillage décrit dans ce document est un ensemble en « T » logé sous l'enceinte et comprenant un mécanisme permettant d'entrainer le mouvement d'un verrou. Lors du processus d'assemblage et de démontage entre une première et une deuxième enceinte, le système de verrouillage est configuré pour prendre une configuration verrouillée dans laquelle un verrou de la première enceinte est logé dans un œillet de la deuxième enceinte et une configuration déverrouillée ou armée dans laquelle le verrou de la première enceinte est retiré de l'œillet de la deuxième enceinte.In this regard, we know for example the document EP 2,640,087 which discloses an acoustic enclosure comprising a device for connection to another acoustic enclosure. The connection device comprises a locking system and an eyelet. The locking system described in this document is a "T" assembly housed under the enclosure and comprising a mechanism for causing the movement of a lock. During the assembly and disassembly process between a first and a second enclosure, the locking system is configured to assume a locked configuration in which a lock of the first enclosure is seated in an eyelet of the second enclosure and an unlocked configuration or army in which the lock of the first enclosure is removed from the eyelet of the second enclosure.

Dans ce contexte d'assemblage d'enceintes acoustiques, d'autres mécanismes peuvent être utilisés dans les systèmes de verrouillage. En particulier, un système de verrouillage comportant un coulisseau, comme celui proposé par le document US8130996 , peut être envisagé. Cependat, il est alors nécessaire de veiller à la stabilité et à la fluidité du système de verrouillage, et d'éviter que le coulisseau déraille de sa zone de coulissage, ce qui pourrait entrainer un blocage du système de verrouillage, en cours de verrouillage ou d'armement.In this context of assembling acoustic enclosures, other mechanisms can be used in the locking systems. In particular, a locking system comprising a slide, such as that proposed by document US8130996 , can be considered. However, it is then necessary to ensure the stability and fluidity of the locking system, and to prevent the slide from derailing from its sliding zone, which could cause the locking system to jam, during locking or armament.

La présente invention a pour but de résoudre au moins l'un des inconvénients précités, pouvant mener aussi à d'autres avantages.The object of the present invention is to resolve at least one of the aforementioned drawbacks, which may also lead to other advantages.

Ainsi, l'invention concerne une armature d'enceinte acoustique comprenant un dispositif de connexion à une autre enceinte acoustique, le dispositif de connexion comportant un œillet et un système de verrouillage, le système de verrouillage comportant :

  • deux pattes, une patte avant et une patte arrière, disposées parallèlement et comprenant chacune un orifice inférieur et un orifice supérieur ;
  • un coulisseau disposé entre les deux pattes et configuré pour coulisser entre une position haute et une position basse, le coulisseau comprenant une ouverture ayant au moins une portion large et au moins une portion étroite, et étant muni de deux éléments de guidage, chacun en appui sur un bord d'au moins l'une des deux pattes de part et d'autre de la patte ;
  • au moins une entretoise reliant les deux pattes l'une à l'autre ;
  • un premier organe élastique relié audit coulisseau et configuré pour ramener automatiquement le coulisseau de la position haute à la position basse ;
  • une vis de sélection comprenant une tige ayant au moins une section large et au moins une section étroite, la tige de la vis de sélection traversant l'orifice supérieur de chacune des pattes et l'ouverture du coulisseau, et étant configurée pour se déplacer entre une position ramenée dans laquelle l'au moins une section large de la tige est dans l'ouverture du coulisseau et une position écartée dans laquelle l'au moins une section étroite de la tige de la vis est dans l'ouverture du coulisseau ;
  • un deuxième organe élastique relié à la vis de sélection et configuré pour ramener automatiquement la vis de sélection de la position écartée à la position ramenée ;
  • un élément de verrouillage comportant une tige de verrouillage configurée pour prendre une position de verrouillage dans laquelle la tige de verrouillage traverse l'orifice inférieur de chacune des deux pattes et une position d'ouverture dans laquelle la tige de verrouillage libère au moins en partie un espace défini entre les deux pattes ;
  • un actionneur configuré pour prendre une position tirée et une position poussée et solidarisé à la vis de sélection et à la tige de verrouillage,
le système de verrouillage étant configuré pour prendre une configuration verrouillée dans laquelle :
  • le coulisseau est en position haute ;
  • la vis de sélection est en position ramenée dans laquelle la section large de la tige est dans la portion large de l'ouverture du coulisseau ; et
  • la tige de verrouillage est en position de verrouillage ;
et une configuration armée dans laquelle :
  • le coulisseau est en position basse ;
  • la vis de sélection est en position écartée dans laquelle la section étroite de la tige est dans l'ouverture du coulisseau ; et
  • la tige de verrouillage est en position d'ouverture,
le système de verrouillage passant de la configuration verrouillée à la configuration armée par déplacement de l'actionneur et de la configuration armée à la configuration verrouillée par déplacement du coulisseau de la position basse à la position haute.Thus, the invention relates to an acoustic enclosure frame comprising a device for connection to another acoustic enclosure, the connection device comprising an eyelet and a locking system, the locking system comprising:
  • two legs, a front leg and a rear leg, arranged in parallel and each comprising a lower orifice and an upper orifice;
  • a slide arranged between the two legs and configured to slide between a high position and a low position, the slide comprising an opening having at least one wide portion and at least one narrow portion, and being provided with two guide elements, each in support on one edge of at least one of the two legs on either side of the leg;
  • at least one spacer connecting the two legs to one another;
  • a first elastic member connected to said slider and configured to automatically return the slider from the high position to the low position;
  • a selection screw comprising a shank having at least one wide section and at least one narrow section, the shank of the selection screw passing through the orifice of each of the legs and the opening of the slider, and being configured to move between a collapsed position in which the at least one wide section of the rod is in the opening of the slider and a spread position in which the at least a narrow section of the shank of the screw is in the opening of the slider;
  • a second elastic member connected to the selection screw and configured to automatically return the selection screw from the separated position to the returned position;
  • a locking member comprising a locking rod configured to assume a locking position in which the locking rod passes through the lower hole of each of the two legs and an open position in which the locking rod releases at least in part one space defined between the two legs;
  • an actuator configured to take a pulled position and a pushed position and secured to the selection screw and to the locking rod,
the locking system being configured to take a locked configuration in which:
  • the slide is in the high position;
  • the selection screw is in the returned position in which the wide section of the rod is in the wide portion of the opening of the slider; and
  • the locking rod is in the locking position;
and an armed configuration in which:
  • the slide is in the low position;
  • the selection screw is in the spread position in which the narrow section of the rod is in the opening of the slider; and
  • the locking rod is in the open position,
the locking system passing from the locked configuration to the armed configuration by moving the actuator and from the armed configuration to the locked configuration by moving the slide from the low position to the high position.

L'armature d'enceinte acoustique ainsi configurée et comportant un tel dispositif de connexion permet un assemblage automatique des enceintes présentant l'avantage d'être simple et plus fiable. Le verrouillage et l'armement du système de verrouillage peuvent être réalisés par un opérateur seul. En approchant une enceinte avec un système de verrouillage en configuration armée d'une autre enceinte, les deux enceintes se verrouillent automatiquement ensembles.The acoustic enclosure frame thus configured and comprising such a connection device allows automatic assembly of the speakers. having the advantage of being simple and more reliable. Locking and arming of the locking system can be done by a single operator. When approaching a speaker with an armed configuration locking system to another speaker, the two speakers automatically lock together.

Les éléments de guidage du coulisseau, en glissant contre les bords des pattes, permettent un bon guidage du coulisseau entre les pattes. Le mouvement de translation du coulisseau est ainsi fluide. En outre, la fluidité du coulissage du coulisseau est améliorée par la présence de l'entretoise reliant les pattes et permettant de maintenir les pattes parallèles en elles, avec une meilleure constance de leur écart l'une par rapport à l'autre.The guide elements of the slide, by sliding against the edges of the legs, allow good guidance of the slide between the legs. The translational movement of the slide is thus fluid. In addition, the fluidity of the sliding of the slide is improved by the presence of the spacer connecting the legs and making it possible to keep the legs parallel in them, with a better constancy of their distance from one another.

L'assemblage et l'armement des enceintes est facilité car au moins une partie des mouvements des différents éléments composant le dispositif de connexion est automatisée. En particulier, l'utilisation du premier organe élastique relié au coulisseau permet d'automatiser le mouvement de translation du coulisseau de la position haute vers la position basse. Et l'utilisation du deuxième organe élastique relié à la vis de sélection permet d'automatiser le déplacement de la vis de sélection de la position écartée à la position ramenée.The assembly and arming of the enclosures is facilitated because at least part of the movements of the various elements making up the connection device is automated. In particular, the use of the first elastic member connected to the slide makes it possible to automate the translational movement of the slide from the high position to the low position. And the use of the second elastic member connected to the selection screw makes it possible to automate the displacement of the selection screw from the separated position to the returned position.

La tige de verrouillage permet d'assurer le bon verrouillage du système de verrouillage et ainsi un assemblage sécurisé des deux enceintes.The locking rod ensures proper locking of the locking system and thus a secure assembly of the two enclosures.

Enfin, l'utilisation de l'actionneur permet de faciliter l'utilisation du système de verrouillage par un opérateur.Finally, the use of the actuator makes it possible to facilitate the use of the locking system by an operator.

Selon une caractéristique, l'élément de verrouillage comporte une collerette solidaire de la tige de verrouillage, la collerette étant formée autour de la tige de verrouillage et ayant un diamètre extérieur supérieur à un diamètre de l'orifice inférieur de la patte avant.According to one characteristic, the locking element comprises a collar integral with the locking rod, the collar being formed around the locking rod and having an outer diameter greater than a diameter of the lower orifice of the front tab.

La collerette constitue également un moyen de sécurisation. La collerette ayant un diamètre extérieur supérieur à un diamètre de l'orifice inférieur de la patte avant, la collerette empêche la tige de verrouillage d'éventuellement passer au-delà des pattes.The collar also constitutes a means of securing. Since the flange has an outside diameter greater than a diameter of the lower hole in the front leg, the flange prevents the locking rod from possibly passing past the legs.

Selon une autre caractéristique, le système de verrouillage comporte une patte de liaison fixée d'une part à l'élément de verrouillage et d'autre part à la vis de sélection, et l'élément de verrouillage est serti sur la patte de liaison.According to another characteristic, the locking system comprises a connecting lug fixed on the one hand to the locking element and on the other hand to the selection screw, and the locking element is crimped on the connecting lug.

Le sertissage de l'élément de verrouillage sur la patte de liaison constitue un moyen de sécurisation supplémentaire de l'assemblage entre l'élément de verrouillage et les pattes. De plus, cela permet de mieux assurer un équerrage entre l'élément de verrouillage et la patte de liaison.The crimping of the locking element on the connecting tab constitutes an additional means of securing the assembly between the locking element and the tabs. In addition, this makes it possible to better ensure squareness between the locking element and the connecting tab.

Selon une caractéristique, l'actionneur comporte une partie surmoulée sur au moins une partie de l'élément de verrouillage.According to one characteristic, the actuator comprises a part overmolded on at least part of the locking element.

Une tel surmoulage favorise la solidarisation de l'actionneur à l'élément de verrouillage.Such an overmolding promotes the securing of the actuator to the locking element.

Selon une autre caractéristique, le système de verrouillage comporte deux entretoises reliant les deux pattes l'une à l'autre, les deux entretoises étant disposées de part et d'autre des pattes.According to another characteristic, the locking system comprises two spacers connecting the two legs to one another, the two spacers being arranged on either side of the legs.

L'utilisation de deux entretoises de part et d'autre des pattes permet d'améliorer encore plus la fluidité du coulissage du coulisseau du fait du maintien du parallélisme des pattes.The use of two spacers on either side of the legs makes it possible to further improve the fluidity of the sliding of the slide due to the maintenance of the parallelism of the legs.

Selon une caractéristique, les pattes comportent chacune deux orifices supérieurs, le système de verrouillage comportant deux vis de sélection, les tiges des deux vis de sélection traversant les orifices supérieurs des deux pattes. L'ouverture du coulisseau comporte au moins deux portions larges et au moins deux portions étroites. Les sections larges des deux vis de sélection sont dans l'ouverture du coulisseau en position ramenée et les sections étroites des deux vis de sélection sont dans l'ouverture en position écartée.According to one characteristic, the legs each have two upper holes, the locking system comprising two selection screws, the rods of the two selection screws passing through the upper holes of the two legs. The opening of the slide has at least two wide portions and at least two narrow portions. The wide sections of the two selector screws are in the opening of the slider in the retracted position and the narrow sections of the two selector screws are in the opening in the spread position.

Selon une autre caractéristique, le coulisseau est muni de deux paires d'éléments de guidage, chaque paire d'éléments de guidage s'appuyant sur un bord d'au moins l'une des deux pattes, de part et d'autre de la patte.According to another characteristic, the slide is provided with two pairs of guide elements, each pair of guide elements resting on an edge of at least one of the two tabs, on either side of the paw.

L'utilisation de quatre éléments de guidage permet d'améliorer encore plus le guidage du coulisseau et donc d'améliorer la fluidité du coulissage.The use of four guide elements makes it possible to further improve the guiding of the slide and therefore to improve the fluidity of the sliding.

Selon une caractéristique, le système de verrouillage est configuré pour prendre une configuration forcée ouverte dans laquelle :

  • le coulisseau est dans une position supérieure ;
  • la vis de sélection est en position écartée dans laquelle la section étroite de la tige est dans l'ouverture du coulisseau ; et
  • la tige de verrouillage est en position d'ouverture,
le système de verrouillage passant à la configuration forcée ouverte par déplacement du coulisseau vers la position supérieure.According to one characteristic, the locking system is configured to take a forced open configuration in which:
  • the slider is in an upper position;
  • the selection screw is in the spread position in which the narrow section of the rod is in the opening of the slider; and
  • the locking rod is in the open position,
the locking system passing to the forced open configuration by moving the slide to the upper position.

En particulier, le système de verrouillage passe de la configuration armée à la configuration forcée ouverte par déplacement du coulisseau de la position basse à la position supérieure. Et le système de verrouillage passe de la configuration verrouillée à la configuration forcée ouverte par déplacement de l'actionneur de la position poussée à la position tirée et du coulisseau de la position haute à la position supérieure.In particular, the locking system switches from the armed configuration to the forced open configuration by moving the slide from the lower position to the upper position. And the locking system changes from the locked configuration to the forced open configuration by moving the actuator from the pushed position to the pulled position and the slide from the high position to the upper position.

La configuration forcée ouverte peut être utilisée lors de la déconnexion de deux enceintes initialement assemblées entre elles. La mise en configuration forcée ouverte permet ainsi d'éviter que les enceintes restent accrochées entre elles après déverrouillage ou déconnexion.The forced open configuration can be used when disconnecting two enclosures initially assembled together. The forced open configuration thus makes it possible to prevent the speakers from remaining hooked together after unlocking or disconnection.

Selon une caractéristique, le coulisseau peut prendre la position haute, la position supérieure et la position basse. La position haute étant une position se situant entre la position supérieure et la position basse.According to one characteristic, the slide can take the high position, the upper position and the lower position. The high position being a position between the upper position and the lower position.

Selon une caractéristique, l'armature comporte deux dispositifs de connexion configurés pour être disposés de part et d'autre de l'enceinte.According to one characteristic, the frame comprises two connection devices configured to be placed on either side of the enclosure.

L'invention concerne également une enceinte acoustique comportant une armature présentant au moins une partie des caractéristiques précédentes.The invention also relates to an acoustic enclosure comprising an armature having at least part of the preceding characteristics.

Enfin, l'invention concerne également un ensemble d'au moins deux enceintes acoustiques comportant une première enceinte acoustique et une deuxième enceinte acoustique comportant chacune une armature présentant au moins une partie des caractéristiques précédentes. L'œillet de la deuxième enceinte est verrouillé dans le système de verrouillage de la première enceinte lorsque les première et deuxième enceintes sont assemblées l'une à l'autre.Finally, the invention also relates to an assembly of at least two acoustic enclosures comprising a first acoustic enclosure and a second acoustic enclosure each comprising an armature having at least part of the preceding characteristics. The eyelet of the second enclosure is locked in the locking system of the first enclosure when the first and second enclosures are assembled together.

Comme visible à la figure 3a présentant en vue éclatée l'un des deux dispositifs de connexion 21 fixé à l'une des deux ailes 202, l'armature 2 comporte ici également une patte intermédiaire 31c disposée entre les pattes 31a, 31b.As visible at the figure 3a showing in exploded view one of the two connection devices 21 fixed to one of the two wings 202, the frame 2 here also comprises an intermediate tab 31c arranged between the tabs 31a, 31b.

La patte intermédiaire 31c est sensiblement parallèle aux pattes 31a, 31b.The intermediate leg 31c is substantially parallel to the legs 31a, 31b.

Les pattes 31a, 31b dépassent d'une extrémité inférieure de la patte intermédiaire 31c de sorte à définir un espace E entre les deux pattes 31a, 31b en-dessous de la patte intermédiaire 31c. Les orifices inférieur 311 et supérieurs 312 sont ici formés dans les portions des pattes 31a, 31b définissant entre elles l'espace E.The legs 31a, 31b protrude from a lower end of the intermediate leg 31c so as to define a space E between the two legs 31a, 31b below the intermediate leg 31c. The lower 311 and upper 312 orifices are here formed in the portions of the legs 31a, 31b defining between them the space E.

Dans cet exemple, la patte intermédiaire 31c comporte l'œillet 210.In this example, the intermediate tab 31c comprises the eyelet 210.

Les pattes 31a, 31b et la patte intermédiaire 31c sont disposées de sorte que seul l'œillet 210 dépasse des extrémités supérieures des pattes 31a, 31b.The legs 31a, 31b and the intermediate leg 31c are arranged so that only the eyelet 210 protrudes from the upper ends of the legs 31a, 31b.

Deux vis de fixation 310 permettent la fixation des pattes 31a, 31b et de la patte intermédiaire 31c à l'une des ailes de retour 202 de la partie de support 20.Two fixing screws 310 allow the fixing of the tabs 31a, 31b and of the intermediate tab 31c to one of the return wings 202 of the support part 20.

Le système de verrouillage 3 comporte également un coulisseau 32, représenté plus en détails aux figures 3b à 3d. Le coulisseau 32 comporte ici une partie de coulissage 320, et est muni d'éléments de guidage 321 et d'un élément de préhension 322.The locking system 3 also includes a slide 32, shown in more detail in figures 3b to 3d . The slide 32 here comprises a sliding part 320, and is provided with guide elements 321 and a gripping element 322.

La partie de coulissage 320 est disposée entre les deux pattes 31a, 31b, notamment dans l'espace E, comme visible sur les figures 4a, 4b, 5a, 5b. La partie de coulissage 320 présente ici une forme sensiblement parallélépipédique et comprend, une face supérieure 320a, une face inférieure 320b, des faces latérales 320c et des faces avant et arrière 320d disposées en vis-à-vis des pattes 31a, 31b.The sliding part 320 is arranged between the two tabs 31a, 31b, in particular in the space E, as visible on the figures 4a , 4b , 5a , 5b . The sliding part 320 here has a substantially parallelepipedal shape and comprises an upper face 320a, a lower face 320b, side faces 320c and front and rear faces 320d arranged opposite the tabs 31a, 31b.

Comme l'illustrent plus en détails les figures 3b à 3d, le coulisseau 32 comprend une ouverture 323, formée ici dans la partie de coulissage 320. L'ouverture 323 est ensuite disposée en regard des orifices supérieurs 312 des pattes 31a, 31b. L'ouverture 323 présente une largeur variable. L'ouverture 323 comprend au moins une portion large 323a et au moins une portion étroite 323b. La portion étroite 323b présente une largeur plus petite que la portion large 323a. L'ouverture 323 comprend dans cet exemple deux portions larges 323a et trois portions étroites 323b. Ici, chacune des portions larges 323a de l'ouverture 323 est disposée entre deux portions étroites 323b et la portion étroite 323b du milieu est entre les deux portions larges 323a, i.e. : une portion étroite 323b, une portion large 323a, une portion étroite 323b, une portion large 323a puis une portion étroite 323b. Autrement dit, les portions larges 323a sont intercalées entre les portions étroites 323b.As illustrated in more detail by figures 3b to 3d , the slide 32 comprises an opening 323, formed here in the sliding part 320. The opening 323 is then placed opposite the upper orifices 312 of the tabs 31a, 31b. The opening 323 has a variable width. The opening 323 includes at least one wide portion 323a and at least one narrow portion 323b. The narrow portion 323b has a smaller width than the wide portion 323a. The opening 323 comprises in this example two wide portions 323a and three narrow portions 323b. Here, each of the wide portions 323a of the opening 323 is disposed between two narrow portions 323b and the narrow portion 323b in the middle is between the two wide portions 323a, ie: a narrow portion 323b, a portion wide 323a, a narrow portion 323b, a wide portion 323a then a narrow portion 323b. In other words, the wide portions 323a are interposed between the narrow portions 323b.

En outre, au moins certaines parties de l'ouverture 323 sont ici entourée d'un rebord 320e en retrait par rapport à au moins la face avant 320d de la partie de coulissage 320 du coulisseau 32.In addition, at least some parts of the opening 323 are here surrounded by a rim 320e set back relative to at least the front face 320d of the sliding part 320 of the slide 32.

En particulier ici, un premier rebord 320e entoure ici une portion étroite 323b et au moins une partie de la portion large 323a juxtaposée, puis un deuxième rebord 320e est formé de part et d'autre de la portion étroite 323b centrale et d'au moins une partie de la portion large 323a suivante, puis un troisième rebord 320e entoure la troisième portion étroite 323b.In particular here, a first rim 320e surrounds here a narrow portion 323b and at least part of the juxtaposed wide portion 323a, then a second rim 320e is formed on either side of the narrow central portion 323b and at least part of the following wide portion 323a, then a third flange 320e surrounds the third narrow portion 323b.

Bien entendu, la forme et les dimensions de l'ouverture du coulisseau peut varier. En particulier, le nombre de portions larges et étroites peut varier.Of course, the shape and dimensions of the opening of the slide can vary. In particular, the number of wide and narrow portions can vary.

Dans le mode de réalisation illustré, les éléments de guidage 321 sont formés en saillie par rapport aux faces latérales 320c de la partie de coulissage 320. Les éléments de guidage 321 sont ici au nombre de quatre, deux éléments de guidage 321 sont en saillie de chaque face latérale 320c de la partie de coulissage 320. Les éléments de guidage 321 sont formés symétriquement de sorte que les éléments de guidage 321 sont formés en saillie des quatre coins de la partie de coulissage 320.In the illustrated embodiment, the guide elements 321 are formed projecting relative to the side faces 320c of the sliding part 320. The guide elements 321 are here four in number, two guide elements 321 are projecting from each side face 320c of the sliding part 320. The guide elements 321 are formed symmetrically so that the guide elements 321 are formed protruding from the four corners of the sliding part 320.

Les éléments de guidage 321 sont disposés à l'extérieur de l'espace E formé entre les pattes 31a, 31b. Chaque élément de guidage 321 s'appuie sur des bords 313 des deux pattes 31a, 31b de part et d'autre des pattes. Les bords 313 des pattes 31a, 31b et faces latérales 320c de la partie de coulissage 320 sont ici coplanaires.The guide elements 321 are arranged outside the space E formed between the tabs 31a, 31b. Each guide element 321 rests on the edges 313 of the two legs 31a, 31b on either side of the legs. The edges 313 of the tabs 31a, 31b and side faces 320c of the sliding part 320 are here coplanar.

Les éléments de guidage 321 présentent ici une forme cylindrique. Les éléments de guidage 321 sont proéminents par rapport aux faces planes externes des pattes avant 31a, arrière 31b.The guide elements 321 here have a cylindrical shape. The guide elements 321 are prominent with respect to the outer flat faces of the front 31a, rear 31b legs.

Les éléments de guidage 321 permettent le guidage du coulisseau 32 dans son mouvement de translation entre les deux pattes 31a, 31b.The guide elements 321 allow the slide 32 to be guided in its translational movement between the two tabs 31a, 31b.

La forme cylindrique des éléments de guidage 32 et leurs dimensions permettent un appui sur plusieurs points contre les bords 313 des deux pattes 31a, 31b. L'appui au niveau de plusieurs points permet d'améliorer le guidage du coulisseau, ainsi que la stabilité du coulisseau et la fluidité du mouvement de coulissage.The cylindrical shape of the guide elements 32 and their dimensions allow a bearing on several points against the edges 313 of the two legs 31a, 31b. The support at several points improves the guiding of the slide, as well as the stability of the slide and the fluidity of the sliding movement.

Selon un exemple de réalisation non représenté, les éléments de guidage 321 peuvent s'appuyer uniquement contre les bords 313 d'une seule des deux pattes 31a, 31b. Les éléments de guidage 321 peuvent également présenter une forme et/ou des dimensions différentes. Par exemple, les éléments de guidage 321 peuvent présenter une forme semi-cylindrique. Le nombre de points d'appui, ou la taille de la surface d'appui, varie en fonction de la forme et des dimensions des éléments de guidage. Par ailleurs, le nombre d'éléments de guidage 321 peut varier. A titre d'exemple, le coulisseau peut comporter uniquement deux éléments de guidage, de préférence de part et d'autre d'au moins l'une des pattes. Enfin, les éléments de guidage 321 peuvent être répartis selon une disposition différente. Trois éléments de guidage 321 peuvent être formés sur une face latérale 320c et un élément de guidage 321 sur l'autre face latérale 320c de la partie de coulissage 320.According to an exemplary embodiment not shown, the guide elements 321 can rest only against the edges 313 of only one of the two tabs 31a, 31b. The guide elements 321 can also have a different shape and / or dimensions. For example, the guide elements 321 can have a semi-cylindrical shape. The number of support points, or the size of the support surface, varies depending on the shape and dimensions of the guide elements. Furthermore, the number of guide elements 321 can vary. By way of example, the slide may comprise only two guide elements, preferably on either side of at least one of the tabs. Finally, the guide elements 321 can be distributed in a different arrangement. Three guide elements 321 can be formed on a side face 320c and a guide element 321 on the other side face 320c of the sliding part 320.

Dans le présent exemple de réalisation, un des éléments de guidage 321 comporte un trou dans lequel est inséré l'élément de préhension 322.In the present exemplary embodiment, one of the guide elements 321 has a hole in which the gripping element 322 is inserted.

L'élément de préhension 322 comporte une partie cylindrique 322a et une poignée 322b, solidaire de la partie cylindrique 322a. L'élément de préhension 322 permet de guider manuellement le coulisseau 32. En effet, par la préhension de la poignée 322b, un opérateur peut faire glisser le coulisseau 32 entre les deux pattes 31a, 31b.The gripping element 322 comprises a cylindrical part 322a and a handle 322b, integral with the cylindrical part 322a. The gripping element 322 makes it possible to manually guide the slide 32. In fact, by gripping the handle 322b, an operator can slide the slide 32 between the two tabs 31a, 31b.

Le système de verrouillage 3 comporte en outre un premier organe élastique 33 relié d'une part au coulisseau 32 et d'autre part à la patte intermédiaire 31c. Le premier organe élastique 33 est ici relié à la partie de coulissage 320 au niveau de la face supérieure 320a.The locking system 3 further comprises a first elastic member 33 connected on the one hand to the slide 32 and on the other hand to the intermediate tab 31c. The first elastic member 33 is here connected to the sliding part 320 at the level of the upper face 320a.

En particulier ici, le premier organe élastique 33 travaille en compression et est configuré pour repousser le coulisseau 32 par rapport à la patte intermédiaire 31c.In particular here, the first elastic member 33 works in compression and is configured to push back the slide 32 relative to the intermediate tab 31c.

Le système de verrouillage 3 comporte deux entretoises 39 (visibles sur les figures 2 et 3a) reliant les pattes 31a, 31b. Les deux entretoises 39 sont disposées de part et d'autre des pattes 31a, 31b. Les entretoises 39 permettent de maintenir constant l'écartement entre les pattes 31a, 31 b. Les pattes 31a, 31 b sont ainsi maintenues parallèles entre elles, ce qui améliore la fluidité du mouvement de translation du coulisseau 32.The locking system 3 comprises two spacers 39 (visible on the figures 2 and 3a ) connecting the legs 31a, 31b. The two spacers 39 are arranged on either side of the legs 31a, 31b. The spacers 39 make it possible to keep the distance between the legs 31a, 31b constant. The legs 31a, 31b are thus kept parallel to each other, which improves the fluidity of the translational movement of the slide 32.

Bien entendu, le nombre d'entretoises 39 peut varier. Une seule entretoise peut par exemple suffire pour relier les deux pattes 31a, 31b.Of course, the number of spacers 39 can vary. A single spacer may for example be sufficient to connect the two legs 31a, 31b.

Le système de verrouillage 3 comporte par ailleurs deux vis de sélection 34 visibles en particulier à la figure 3a. Les vis de sélection 34 sont introduites dans les orifices supérieurs 312 des pattes et traversent l'ouverture 323 du coulisseau 32.The locking system 3 also comprises two selection screws 34 visible in particular at the figure 3a . The selection screws 34 are introduced into the upper holes 312 of the tabs and pass through the opening 323 of the slider 32.

Chaque vis de sélection 34 comprend une tête 340 et une tige 341. La tige 341 de chaque vis de sélection 34 comprend une partie large 341a ayant une section dite large et une partie étroite 341b ayant une section dite étroite, de diamètre inférieur à celui de la section large. La partie large 341a est dimensionnée de sorte à correspondre sensiblement aux portions larges 323a de l'ouverture 323 : elle présente par exemple un diamètre plus grand que la largeur des portions étroites 323b et au maximum égal à la largeur des portions larges 323a. La partie étroite 341b est dimensionnée de sorte à correspondre au plus à la largeur des portions étroites 323b de l'ouverture 323. La tête 340 de chaque vis de sélection 34 présente au moins une section ayant un diamètre plus large que l'ouverture et notamment des portions larges 323a. La tête 340 de chaque vis de sélection 34 permet ainsi d'éviter que la vis de sélection 34 ne se désolidarise du coulisseau 32 et en particulier que la vis de sélection 34 ne se retire complètement de l'ouverture 323.Each selection screw 34 comprises a head 340 and a rod 341. The rod 341 of each selection screw 34 comprises a wide portion 341a having a so-called wide section and a narrow portion 341b having a so-called narrow section, of diameter smaller than that of the wide section. The wide part 341a is dimensioned so as to correspond substantially to the wide portions 323a of the opening 323: it has for example a diameter greater than the width of the narrow portions 323b and at most equal to the width of the wide portions 323a. The narrow part 341b is dimensioned so as to correspond at most to the width of the narrow portions 323b of the opening 323. The head 340 of each selection screw 34 has at least one section having a diameter larger than the opening and in particular large portions 323a. The head 340 of each selection screw 34 thus makes it possible to prevent the selection screw 34 from becoming detached from the slide 32 and in particular that the selection screw 34 from being completely withdrawn from the opening 323.

Le système de verrouillage 3 comporte également un bloc guide 343. Le bloc guide 343 entoure une partie des vis de sélection 34, ici la tête 340 et une partie de la tige 341 de chaque vis de sélection 34. Le bloc guide 343 présente ici une forme parallélépipédique et s'appuie contre la patte arrière 31b. Le bloc guide 343 permet le guidage du mouvement de translation des vis de sélection 34.The locking system 3 also comprises a guide block 343. The guide block 343 surrounds a part of the selection screws 34, here the head 340 and a part of the rod 341 of each selection screw 34. The guide block 343 has here a parallelepipedal shape and rests against the rear leg 31b. The guide block 343 allows the guiding of the translational movement of the selection screws 34.

Le système de verrouillage 3 comporte en outre un deuxième organe élastique 342, schématisé figure 3a.The locking system 3 further comprises a second elastic member 342, shown diagrammatically. figure 3a .

Le deuxième organe élastique 342 est ici disposé dans le bloc guide 343 et relié à chaque vis de sélection 34.The second elastic member 342 is here arranged in the guide block 343 and connected to each selection screw 34.

En particulier, le deuxième organe élastique 342 entoure une partie de la tige de la vis de sélection 34 et est maintenu en compression entre la tête de la vis de sélection 34 et un fond du bloc guide 343, accolé à la patte arrière 31b.In particular, the second elastic member 342 surrounds a part of the rod of the selection screw 34 and is held in compression between the head of the selection screw 34 and a bottom of the guide block 343, attached to the rear leg 31b.

Le deuxième organe élastique 342 est ainsi configuré pour repousser la tête de vis correspondante et ainsi entrainer l'actionneur 38 en position poussée, comme expliqué ci-après.The second elastic member 342 is thus configured to push back the corresponding screw head and thus drive the actuator 38 in the pushed position, as explained below.

Dans le mode de réalisation décrit, le système de verrouillage 3 comporte également un élément de verrouillage, schématisé figure 4b par exemple. L'élément de verrouillage comporte une tige de verrouillage 35 et une collerette 37 solidarisées l'une à l'autre.In the embodiment described, the locking system 3 also comprises a locking element, shown diagrammatically. figure 4b for example. The locking element comprises a locking rod 35 and a collar 37 secured to one another.

La tige de verrouillage 35 est ici disposée en-dessous du coulisseau 32. La tige de verrouillage 35 est introduite au moins dans l'orifice inférieur 311 de la patte avant 31a.The locking rod 35 is here disposed below the slide 32. The locking rod 35 is introduced at least into the lower hole 311 of the front tab 31a.

La collerette 37 est formée autour de la tige de verrouillage 35. La collerette 37 est formée à l'extérieur de l'espace formé entre les deux pattes 31a, 31b, face à la patte avant 31a. La collerette 37 présente un diamètre extérieur supérieur à un diamètre de l'orifice inférieure 311 de la patte avant 31a.The collar 37 is formed around the locking rod 35. The collar 37 is formed outside the space formed between the two tabs 31a, 31b, facing the front tab 31a. The collar 37 has an outer diameter greater than a diameter of the lower orifice 311 of the front leg 31a.

Le système de verrouillage 3 comporte ici une patte de liaison 36 disposée face à la patte avant 31a. La patte de liaison 36 et la patte avant 31a sont disposées ici parallèlement. La patte de liaison 36 comprend ici trois trous traversants (indiqués figures 5b) ; deux trous traversants supérieurs 360 formés en vis-à-vis avec les orifices supérieurs 312 des pattes 31a, 31b et un trou traversant 361 formé en vis-à-vis avec l'orifice inférieur 311 des pattes 31a, 31b. La tige de verrouillage 35 et les deux vis de sélection 34 sont respectivement introduites dans les trous traversants supérieurs 360 et inférieur 361. L'angle formé par la tige de verrouillage 35 et la patte de liaison 36 est ici un angle droit.The locking system 3 here comprises a connecting tab 36 disposed facing the front tab 31a. The connecting tab 36 and the front tab 31a are here arranged parallel. The connecting tab 36 here comprises three through holes (indicated figures 5b ); two upper through holes 360 formed vis-à-vis the upper orifices 312 of the legs 31a, 31b and a through-hole 361 formed vis-à-vis the lower orifice 311 of the legs 31a, 31b. The locking rod 35 and the two selection screws 34 are respectively introduced into the upper 360 and lower 361 through holes. The angle formed by the locking rod 35 and the connecting tab 36 is here a right angle.

L'élément de verrouillage est serti sur la patte de liaison 36. En cas de désolidarisation de la tige de verrouillage 35 et la patte de liaison 36, la collerette 37 empêche la tige de verrouillage 35 de glisser au-delà des pattes 31a, 31b. La collerette 37 constitue ainsi un moyen de sécurisation du verrouillage du système de verrouillage 3.The locking element is crimped on the connecting tab 36. In the event of the locking rod 35 being detached from the connecting tab 36, the flange 37 prevents the locking rod 35 from sliding past the tabs 31a, 31b. . The collar 37 thus constitutes a means of securing the locking of the locking system 3.

Dans l'exemple de réalisation illustré, un actionneur 38 est relié aux vis de sélection 34 et à la tige de verrouillage 35. L'actionneur 38 présente ici une forme de poignée et s'appuie contre la patte avant 31a. L'actionneur 38 permet la préhension, par exemple par un opérateur, des vis de sélection 34 et de la tige de verrouillage 35.In the illustrated embodiment, an actuator 38 is connected to the selection screw 34 and to the locking rod 35. The actuator 38 here has the shape of a handle and rests against the front tab 31a. The actuator 38 allows the gripping, for example by an operator, of the selection screws 34 and of the locking rod 35.

L'actionneur 38 est ici formé par surmoulage sur au moins la tige de verrouillage 35 et la patte de liaison 36. De préférence, le surmoulage est effectué ultérieurement à l'assemblage de la patte de liaison 36 à la tige de verrouillage 35. Cela permet de garantir un équerrage entre la tige de verrouillage 35 et la patte de verrouillage 36.The actuator 38 is here formed by overmolding on at least the locking rod 35 and the connecting lug 36. Preferably, the overmolding is carried out subsequent to the assembly of the connecting lug 36 to the locking rod 35. This makes it possible to guarantee a squaring between the locking rod 35 and the locking tab 36.

Chaque système de verrouillage 3 peut prendre une configuration verrouillée, une configuration armée et une configuration forcée ouverte. L'enceinte 1 est assemblée à une autre enceinte lorsque les deux systèmes de verrouillage 3 sont dans la configuration verrouillée, c'est-à-dire avec l'œillet de l'une verrouillé dans le système de verrouillage de l'autre. Lorsque les deux systèmes de verrouillage 3 sont en position armée, les deux enceintes ne sont pas assemblées. Les différentes configurations sont détaillées plus loin dans le présent document.Each locking system 3 can take a locked configuration, an armed configuration and a forced open configuration. The enclosure 1 is assembled with another enclosure when the two locking systems 3 are in the locked configuration, that is to say with the eyelet of one locked in the locking system of the other. When the two locking systems 3 are in the armed position, the two enclosures are not assembled. The different configurations are detailed later in this document.

Dans le mode de réalisation décrit, le coulisseau 32 peut coulisser verticalement entre les deux pattes 31a, 31b. Le coulisseau 32 peut prendre une position haute lorsque le système de verrouillage 3 est dans la configuration verrouillée, une position supérieure lorsque le système de verrouillage est dans la configuration forcée ouverte et une position basse lorsque le système de verrouillage 3 est dans la configuration armée.In the embodiment described, the slide 32 can slide vertically between the two tabs 31a, 31b. The slider 32 can take a high position when the locking system 3 is in the locked configuration, an upper position when the locking system is in the forced open configuration and a low position when the locking system 3 is in the armed configuration.

Dans les positions haute et supérieure, le premier organe élastique 33 est comprimé. Dans la position basse, le premier organe élastique 33 est relâché. Le premier organe élastique 33 est configuré pour ramener automatiquement le coulisseau 32 de la position haute à la position basse.In the upper and upper positions, the first elastic member 33 is compressed. In the low position, the first elastic member 33 is released. The first elastic member 33 is configured to automatically return the slider 32 from the high position to the low position.

Chaque vis de sélection 34 peut se déplacer entre une position ramenée, et une position écartée. La vis de sélection 34 est dans la position ramenée lorsque le système de verrouillage 3 est en configuration verrouillée. La vis de sélection 34 est dans la position écartée lorsque le système de verrouillage 3 est en configuration armée ou en configuration forcée ouverte. En position ramenée, la section large de la tige 341 de la vis de sélection 34 est dans l'ouverture 323 du coulisseau 32. En position écartée, la section étroite de la tige 341 de la vis 34 est dans l'ouverture 323 du coulisseau 32. Le deuxième organe élastique 342 est configuré pour ramener automatiquement la vis de sélection 34 correspondante de la position écartée à la position ramenéeEach selection screw 34 can move between a returned position and a separated position. The selection screw 34 is in the position returned when the locking system 3 is in the locked configuration. The selection screw 34 is in the separated position when the locking system 3 is in the armed configuration or in the forced open configuration. In the retracted position, the wide section of the rod 341 of the selection screw 34 is in the opening 323 of the slider 32. In the extended position, the narrow section of the rod 341 of the screw 34 is in the opening 323 of the slider. 32. The second resilient member 342 is configured to automatically return the corresponding selection screw 34 from the separated position to the returned position.

La tige de verrouillage 35 se déplace de sorte à prendre deux positions ; une position de verrouillage et une position d'ouverture. La tige de verrouillage 35 est en position de verrouillage lorsque le système de verrouillage 3 est en configuration verrouillée. La tige de verrouillage 35 est en position d'ouverture lorsque le système de verrouillage 3 est en configuration armée ou en configuration forcée ouverte. En position de verrouillage, la tige de verrouillage 35 traverse l'orifice inférieur 311 de chacune des deux pattes 31a, 31b. En position d'ouverture, la tige de verrouillage 35 libère au moins en partie l'espace E défini entre les deux pattes 31a, 31b. Lorsque chaque deuxième organe élastique 342 ramène la vis de sélection 34 correspondante de la position écartée vers la position ramenée, la tige de verrouillage 35 est ramenée automatiquement de la position d'ouverture à la position de verrouillage.The locking rod 35 moves so as to take two positions; a locking position and an open position. The locking rod 35 is in the locking position when the locking system 3 is in the locked configuration. The locking rod 35 is in the open position when the locking system 3 is in the armed configuration or in the forced open configuration. In the locked position, the locking rod 35 passes through the lower orifice 311 of each of the two tabs 31a, 31b. In the open position, the locking rod 35 releases at least part of the space E defined between the two tabs 31a, 31b. When each second resilient member 342 returns the corresponding selection screw 34 from the separated position to the returned position, the locking rod 35 is automatically returned from the open position to the locking position.

L'actionneur 38 est configuré pour prendre une position tirée et une position poussée. En position tirée, l'actionneur 38 permet de positionner les vis de sélection 34 dans la position écartée et la tige de verrouillage 35 dans la position d'ouverture de sorte à positionner le système de verrouillage 3 en configuration armée. Lorsque chaque deuxième organe élastique 342 ramène la vis de sélection 34 correspondante de la position écartée vers la position ramenée, l'actionneur 38 est ramené automatiquement de la position tirée vers la position poussée. En position poussée, l'actionneur 38 est ici en appui contre la patte avant 31a.Actuator 38 is configured to assume a pulled position and a pushed position. In the pulled position, the actuator 38 makes it possible to position the selection screws 34 in the separated position and the locking rod 35 in the open position so as to position the locking system 3 in the armed configuration. When each second elastic member 342 returns the corresponding selection screw 34 from the separated position to the returned position, the actuator 38 is automatically returned from the pulled position to the pushed position. In the pushed position, the actuator 38 is here resting against the front tab 31a.

L'armement et le verrouillage d'une première enceinte 1 avec une deuxième enceinte 1' par le dispositif de connexion 21 tel que décrit précédemment est expliqué relativement aux figures 4a, 4b, 5a, 5b, 6. En particulier, les figures 4a, 4b illustrent le système de verrouillage en configuration armée. Les figures 5a, 5b illustrent le système de verrouillage en configuration verrouillée. La figure 6 représente la première et la deuxième enceintes 1, 1' assemblées entre elles.The arming and locking of a first enclosure 1 with a second enclosure 1 'by the connection device 21 as described above is explained in relation to figures 4a , 4b , 5a , 5b , 6 . In particular, the figures 4a , 4b illustrate the locking system in armed configuration. The figures 5a , 5b illustrate the locking system in locked configuration. The figure 6 shows the first and second enclosures 1, 1 'assembled together.

La deuxième enceinte 1' est ici identique à la première enceinte 1. Les éléments correspondants comportent donc les mêmes références numériques, surmontées d'un signe « ' » (prime).The second enclosure 1 'is here identical to the first enclosure 1. The corresponding elements therefore have the same numerical references, surmounted by a sign “'” (prime).

Toutefois, pour assembler deux enceintes, il faut au moins que la deuxième enceinte comporte un ou plusieurs œillets capables d'être verrouillés dans le système de verrouillage de la première enceinte.However, to assemble two enclosures, at least the second enclosure must have one or more eyelets capable of being locked in the locking system of the first enclosure.

Les opérations d'armement, de verrouillage et de déverrouillage sont décrites pour un seul dispositif de connexion 21 et donc un seul système de connexion 3 et un œillet 210 de la première enceinte 1 ainsi que pour un seul dispositif de connexion 21' et un seul système de verrouillage 3' et un œillet 210' (non visible sur la figure 6) de la deuxième enceinte 1'. Bien entendu, cette description reste valable pour les deux dispositifs de connexion 21 de la première enceinte 1 et les deux dispositifs de connexion 21' de la deuxième enceinte 1'.The arming, locking and unlocking operations are described for a single connection device 21 and therefore a single connection system 3 and an eyelet 210 of the first enclosure 1 as well as for a single connection device 21 'and a single one. 3 'locking system and a 210' eyelet (not visible on the figure 6 ) of the second enclosure 1 '. Of course, this description remains valid for the two connection devices 21 of the first enclosure 1 and the two connection devices 21 'of the second enclosure 1'.

Les étapes d'armement de la première enceinte 1 sont les suivantes.The steps for arming the first enclosure 1 are as follows.

La tige de verrouillage 35 et les vis de sélection 34 sont tirées au moyen de l'actionneur 38. La tige de verrouillage 35 est amenée vers la position d'ouverture ; la tige de verrouillage 35 est retirée au moins de l'orifice inférieur 311 de la patte arrière 31b de l'enceinte 1 et de l'orifice de l'œillet 210' de l'autre enceinte 1' si un œillet y était verrouillé. La tige de verrouillage 35 libère au moins en partie l'espace E défini entre les deux pattes 31a, 31b. La tige de verrouillage 35 reste possiblement enfoncée dans l'orifice inférieur 311 de la patte avant 31a (elle peut toutefois en être dégagé aussi). Les vis de sélection 34 étant tirées, les sections larges des tiges 341 de vis de sélection 34 sont retirées de l'ouverture 323 du coulisseau 32. Les vis de sélection 34 prennent la position écartée. Le deuxième organe élastique 342 de chaque vis de sélection 34 est comprimé. Les portions larges 323a de l'ouverture 323 entourent donc les sections étroites des tiges 341 des vis de sélection. Le premier organe élastique 33 se relâche et repousse ainsi le coulisseau qui coulisse alors vers le bas de sorte à prendre la position basse. Le coulisseau 32 coulisse jusqu'à ce qu'au moins l'une des vis de sélection 34 soit en appui contre une surface inférieure S du coulisseau 32 formée dans l'ouverture 323 et formant butée pour l'au moins une vis de sélection 34. En particulier, les parties étroites 341b des vis de sélection 34 se retrouvent alors positionnées dans des portions étroites 323b de l'ouverture 323 du coulisseau 32. En outre, une partie large 341a d'une vis de sélection 34 se retrouve alors en appui contre une partie du rebord 320e. Le système est ainsi bloqué en configuration armée.The locking rod 35 and the selection screws 34 are pulled by means of the actuator 38. The locking rod 35 is brought to the open position; the locking rod 35 is withdrawn at least from the lower hole 311 of the rear leg 31b of the enclosure 1 and from the hole in the eyelet 210 'of the other enclosure 1' if an eyelet was locked therein. The locking rod 35 releases at least part of the space E defined between the two tabs 31a, 31b. The locking rod 35 possibly remains depressed in the lower hole 311 of the front tab 31a (it can however also be released). With the selector screws 34 pulled out, the wide sections of the selector screw rods 341 34 are withdrawn from the opening 323 of the slider 32. The selector screws 34 assume the extended position. The second elastic member 342 of each selection screw 34 is compressed. The wide portions 323a of the opening 323 therefore surround the narrow sections of the rods 341 of the selection screws. The first elastic member 33 relaxes and thus pushes back the slide which then slides downwards so as to take the low position. The slide 32 slides until at least one of the selection screws 34 bears against a lower surface S of the slide 32 formed in the opening 323 and forming a stop for the at least one selection screw 34 In particular, the narrow parts 341b of the selection screw 34 are then found positioned in narrow portions 323b of the opening 323 of the slide 32. In addition, a wide part 341a of a selection screw 34 is then found in abutment. against part of the 320th ledge. The system is thus blocked in armed configuration.

Le système de verrouillage 3 de la première enceinte 1 est ainsi en configuration armée. La première enceinte 1 est alors prête à être assemblée à la deuxième enceinte 1'.The locking system 3 of the first enclosure 1 is thus in an armed configuration. The first enclosure 1 is then ready to be assembled to the second enclosure 1 '.

Les étapes de l'assemblage des deux enceintes 1, 1' sont les suivantes.The steps for assembling the two speakers 1, 1 'are as follows.

La deuxième enceinte 1' est disposée en-dessous de la première enceinte 1, laquelle est mise en configuration armée. Dans le mode de réalisation illustré, la paroi supérieure 10' de la deuxième enceinte 1' est disposée en vis-à-vis avec la paroi inférieure 11 de la première enceinte 1.The second enclosure 1 'is arranged below the first enclosure 1, which is placed in armed configuration. In the illustrated embodiment, the upper wall 10 'of the second enclosure 1' is arranged vis-à-vis the lower wall 11 of the first enclosure 1.

L'œillet 210' de la deuxième enceinte 1' est disposé entre les pattes 31a, 31b de la première enceinte 1 au niveau de l'espace E. L'œillet 210' de la deuxième enceinte 1' est amené en appui contre le coulisseau 32 de la première enceinte 1, en particulier sur la face inférieure 320b de la partie de coulissage 320. Le coulisseau 32 de la première enceinte 1 coulisse vers le haut, en étant repoussé par l'œillet 210'. Le premier organe élastique 33 est alors comprimé et le coulisseau 32 prend alors la position haute.The eyelet 210 'of the second enclosure 1' is disposed between the tabs 31a, 31b of the first enclosure 1 at the level of the space E. The eyelet 210 'of the second enclosure 1' is brought to bear against the slide 32 of the first enclosure 1, in particular on the lower face 320b of the sliding part 320. The slide 32 of the first enclosure 1 slides upwards, being pushed back by the eyelet 210 '. The first elastic member 33 is then compressed and the slide 32 then takes the high position.

En passant dans la position haute du coulisseau, les deux vis de sélection 34 se retrouvent respectivement dans les deux portions larges 323a de l'ouverture 323. Le deuxième organe élastique 342 de chaque vis de sélection 34 ramène alors automatiquement les vis de sélection 34 vers la position ramenée. Dans le même temps, sous l'effet des deuxièmes organes élastiques 342 qui, en ramenant les vis de sélection 34, entraine l'actionneur 38, la tige de verrouillage 35 est aussi ramenée vers la position de verrouillage. En position de verrouillage, la tige de verrouillage 35 traverse les orifices inférieurs 311 des pattes 31a, 31b de la première enceinte 1 et l'œillet 210' de la deuxième enceinte 1'. Le système de verrouillage 3 de la première enceinte 1 est ainsi en configuration verrouillée, c'est-à-dire que l'œillet 210' de la deuxième enceinte 1' est engagé dans le système de verrouillage 3 de la première enceinte 1. La tige de verrouillage 35 garantit un bon verrouillage de l'œillet 210' de la deuxième enceinte 1' dans le système de verrouillage 3 de la première enceinte 1.Passing into the high position of the slide, the two selection screws 34 are found respectively in the two wide portions 323a of the opening 323. The second elastic member 342 of each selection screw 34 then automatically returns the selection screws 34 towards the brought back position. At the same time, under the effect of the second elastic members 342 which, by returning the selection screws 34, drives the actuator 38, the locking rod 35 is also returned to the locking position. In the locked position, the locking rod 35 passes through the lower holes 311 of the legs 31a, 31b of the first enclosure 1 and the eyelet 210 'of the second enclosure 1'. The locking system 3 of the first enclosure 1 is thus in the locked configuration, that is to say that the eyelet 210 'of the second enclosure 1' is engaged in the locking system 3 of the first enclosure 1. The Locking rod 35 guarantees good locking of the eyelet 210 'of the second enclosure 1' in the locking system 3 of the first enclosure 1.

Le déverrouillage des deux enceintes 1, 1' est réalisé en désarmant la première enceinte 1. Cela permet de retirer l'œillet 210' de la deuxième enceinte 1' de sa position de verrouillage dans le système de verrouillage 3 de la première enceinte 1.The two enclosures 1, 1 'are unlocked by disarming the first enclosure 1. This allows the eyelet 210' of the second enclosure 1 'to be removed from its locking position in the locking system 3 of the first enclosure 1.

Lors du déverrouillage, afin d'éviter que les enceintes restent accrochées entre elles, la première enceinte 1 peut être positionnée dans la configuration forcée ouverte. L'actionneur 38 est mis en position tirée, entrainant alors les vis de sélection 34 en position écartée et la tige de verrouillage 35 en position d'ouverture. La première enceinte 1 peut alors être amenée dans une configuration forcée ouverte. Pour cela, le coulisseau 32 est repoussé vers le haut davantage au moyen de l'élément de préhension 322. Le coulisseau 32 est repoussé vers la position supérieure, position se trouvant ici plus haut que la position haute, c'est-à-dire une position dans laquelle le coulisseau est plus près de la patte intermédiaire 31c et où le premier organe élastique 33 est plus comprimé que dans la position haute. Les vis de sélection 34 se trouvent ainsi dans la portion étroite 323b intermédiaire et la portion étroite 323b inférieure de l'ouverture 323. Les portions étroites 323b de l'ouverture 323 entourent la section étroite de la tige 341 de chaque vis de sélection 34 et la partie large 341a correspondante de la tige 341 est alors en appui contre une partie du rebord 320e. Le système de verrouillage 3 est ainsi bloqué dans la configuration forcée ouverte.When unlocking, in order to prevent the enclosures from remaining hooked together, the first enclosure 1 can be positioned in the forced open configuration. The actuator 38 is put in the pulled position, then driving the selection screws 34 in the separated position and the locking rod 35 in the open position. The first enclosure 1 can then be brought into a forced open configuration. For this, the slider 32 is pushed further upwards by means of the gripping element 322. The slider 32 is pushed back to the upper position, a position here being higher than the upper position, that is to say a position in which the slider is closer to the intermediate tab 31c and where the first elastic member 33 is more compressed than in the high position. The selection screws 34 are thus located in the narrow intermediate portion 323b and the lower narrow portion 323b of the opening 323. The narrow portions 323b of the opening 323 surround the narrow section of the rod 341 of each selection screw 34 and the corresponding wide part 341a of the rod 341 then bears against a part of the rim 320e. The locking system 3 is thus blocked in the forced open configuration.

La première enceinte 1 est ainsi prête à être assemblée avec une autre enceinte acoustique.The first enclosure 1 is thus ready to be assembled with another acoustic enclosure.

Afin de permettre un assemblage automatique de la deuxième enceinte 1' avec la première enceinte 1, la première enceinte 1 doit être armée.In order to allow automatic assembly of the second enclosure 1 'with the first enclosure 1, the first enclosure 1 must be armed.

La configuration forcée ouverte du système de verrouillage de la première enceinte 1 a été décrite partant de la configuration verrouillée. Bien entendu, la première enceinte 1 peut être mise en configuration forcée ouverte après avoir été complètement armée.The forced open configuration of the locking system of the first enclosure 1 has been described starting from the locked configuration. Of course, the first enclosure 1 can be placed in the forced open configuration after having been fully armed.

Par ailleurs, dans l'exemple décrit, l'enceinte peut être mise en configuration par déplacement du coulisseau 32 vers la position supérieure au moyen de l'élément de préhension 322. Bien entendu, le déplacement du coulisseau peut être réalisé autrement, notamment au moyen d'un élément de préhension différent ou par la préhension directe et déplacement de la partie de coulissage 320.Furthermore, in the example described, the enclosure can be configured by moving the slide 32 to the upper position by means of the gripping element 322. Of course, the movement of the slide can be achieved otherwise, in particular by means of the gripping element 322. by means of a different gripping element or by the direct gripping and displacement of the sliding part 320.

Dans cet exemple, les étapes d'assemblage et de déverrouillage précédemment décrites sont réalisées de préférence simultanément pour les deux systèmes de verrouillage 3 de la première enceinte 1 et les deux œillets 210' de la deuxième enceinte 1'. De même, les étapes d'armement et de mise en configuration forcée ouverte de la première enceinte 1 peuvent être réalisées simultanément pour les deux systèmes de verrouillage 3.In this example, the assembly and unlocking steps described above are preferably carried out simultaneously for the two locking systems 3 of the first enclosure 1 and the two eyelets 210 'of the second enclosure 1'. Likewise, the arming and forced open configuration steps of the first enclosure 1 can be carried out simultaneously for the two locking systems 3.

Bien entendu, la présente invention n'est pas limitée au mode de réalisation décrit ci-avant, dans les limites de la protection définie par les revendications.Of course, the present invention is not limited to the embodiment described above, within the limits of the protection defined by the claims.
