Abstract

The enclosure (2) has a mechanical connection device for connecting with another enclosure. The connection device includes a mechanism for converting a translation movement of a handle (6) in a direction into lateral movements of a bolt in another direction that is different from the former direction. A cam defines a cam path adapted to guide a pin interdependent of the bolt. The path comprises a recess, where the pin is immobilized by a spring. A rod is mounted with sliding motion in a body, where a rotary component i.e. wheel (10), is rotatably mounted about a main axis of a piston (8).

Description

L'invention concerne une enceinte acoustique avec un dispositif de connexion mécanique à une autre enceinte et/ou un dispositif de réglage d'angle inter-enceintes.The invention relates to an acoustic enclosure with a device for mechanical connection to another enclosure and / or an inter-enclosure angle adjustment device.

L'assemblage d'enceintes de sonorisation professionnelle en colonne (ou « line arrays ») s'est généralisé depuis plus de 10 ans. Ces assemblages peuvent être constitué de plusieurs dizaine d'enceintes, pesant chacune plus de 50 kg.The assembly of speakers professional sound column (or " line arrays ") has been widespread for more than 10 years. These assemblies can consist of several dozen speakers, each weighing more than 50 kg.

Il a donc été proposé des systèmes d'accrochages que l'on peut scinder en deux catégories : les cadres (ou « bumpers ») qui connectent l'enceinte supérieure aux moteurs de levage, et la mécanique d'accrochage de chaque enceinte assurant la connexion des enceintes entre elles.It has therefore been proposed clash systems that can be divided into two categories: frames (or " bumpers ") that connect the upper enclosure to the lifting motors, and the attachment mechanism of each enclosure ensuring the connecting the speakers together.

La plupart de systèmes d'accrochage inter-enceinte présentent les particularités suivantes :

  • les enceintes sont accrochées suivant un mode de montage en tension, auquel cas c'est la force de gravité qui amène les enceintes à leurs angles définitifs, ou suivant un mode de montage en compression, auquel cas c'est une force de rappel appliquée en bas de l'assemblage qui amène les enceintes à leurs angles définitifs ;
  • ils se font sur 4 points, ce qui représente une sur-contrainte dans la définition d'un plan de sorte que le quatrième point est toujours difficile à connecter ;
  • ils ont recours à des broches à bille (en anglais « bail-lock » ou « puick release pin ») et la tolérance sur les trous recevant ces broches à bille doit de ce fait être définie de manière excessivement stricte (trou trop petit, la broche ne rentre pas ; trou trop grand, la broche n'est plus retenue) ;
  • ces broches assurent à la fois la connexion inter-enceintes et le réglage d'angles inter-enceintes (les réglages d'angles sont généralement compris entre 0 et 10°), ce qui complexifie le système et son assemblage, d'autant que les réglages d'angle doivent être identiques de chaque côté des enceintes ;
  • les broches à billes sont des pièces dissociées de l'enceinte qui se perdent facilement.
Most inter-enclosure systems have the following characteristics:
  • the loudspeakers are hung in a voltage-mount mode, in which case it is the force of gravity that brings the loudspeakers to their final angles, or in a compression-mount mode, in which case it is a restoring force applied in bottom of the assembly that brings the speakers to their final angles;
  • they are done on 4 points, which represents an over-constraint in the definition of a plan so that the fourth point is always difficult to connect;
  • they use ball -lock pins (English " bail-lock " or " puick release pin ") and the tolerance on the holes receiving these ball pins must therefore be defined excessively strict (hole too small, the pin does not fit, hole too big, pin is no longer retained);
  • these pins provide both the inter-speaker connection and the inter-speaker angle adjustment (the angle settings are generally between 0 and 10 °), which complicates the system and its assembly, especially since the angle settings must be identical on each side of the speakers;
  • the ball pins are parts dissociated from the enclosure which are easily lost.

Ces difficultés sont amplifiées dans le cas d'un montage en tension des enceintes l'une par rapport à l'autre car le mode d'accrochage des enceintes suppose de soulever manuellement l'arrière de celles-ci pour insérer les broches à bille dans les trous correspondant aux valeurs requises d'angles entre les enceintes.These difficulties are amplified in the case of a voltage mounting of the speakers relative to each other because the attachment mode of the speakers involves manually lifting the rear thereof to insert the ball pins in the holes corresponding to the required values of angles between the speakers.

En conséquence, ces systèmes actuels sont complexes à assembler, et requièrent au minimum 2 à 3 techniciens expérimentés. Un tel assemblage nécessite de plus un temps précieux lorsqu'il est réalisé en vue d'un concert ayant lieu le soir même.As a result, these current systems are complex to assemble, and require at least 2 to 3 experienced technicians. Such an assembly also requires precious time when it is made for a concert taking place the same evening.

On connaît par ailleurs les solutions décrites dans les brevets US 7 328 769 , US 7 298 860 et US 7 634 100 .We also know the solutions described in the patents US 7,328,769 , US 7,298,860 and US 7,634,100 .

Dans ce contexte, l'invention propose une enceinte acoustique comprenant un dispositif de connexion mécanique avec une autre enceinte acoustique, caractérisée en ce que le dispositif de connexion comprend un mécanisme de conversion d'une commande en translation selon une première direction en un mouvement de translation d'au moins un premier verrou selon une seconde direction différente de la première direction.In this context, the invention proposes an acoustic enclosure comprising a mechanical connection device with another acoustic enclosure, characterized in that the connection device comprises a mechanism for converting a translation control in a first direction into a movement of translation of at least a first latch in a second direction different from the first direction.

On peut ainsi notamment positionner la commande en un endroit de l'enceinte facilement accessible. Dans le même ordre d'idée, le mouvement réalisé par l'opérateur pour activer la commande peut ainsi se faire dans une direction souhaitable sur le plan pratique (et non nécessairement dans la direction de déplacement du verrou).It is thus possible to position the control in a place of the easily accessible enclosure. In the same vein, the movement made by the operator to activate the control can be done in a desirable direction on the practical level (and not necessarily in the direction of movement of the lock).

Le mécanisme de conversion peut en outre convertir la commande en translation en un mouvement de translation d'un second verrou, ce qui permet de piloter deux points de verrouillage à partir d'une commande unique.The conversion mechanism can further convert the translation control into a translational movement of a second latch, thereby controlling two latching points from a single command.

Le mouvement de translation du second verrou est par exemple dans la seconde direction avec un sens opposé au mouvement de translation du premier verrou, ce qui permet, au moyen de la commande précitée, la connexion simultanée des deux côtés opposés de l'enceinte.The translational movement of the second latch is for example in the second direction with a direction opposite to the translation movement of the first lock, which allows, by means of the aforementioned command, the simultaneous connection of the two opposite sides of the enclosure.

Le mécanisme de conversion peut comprendre en pratique une came entraînée par ladite commande. Une telle came permet de mettre en oeuvre le changement de direction, ainsi qu'éventuellement la démultiplication ou la surmultiplication du mouvement, par le choix notamment d'un chemin de came approprié.The conversion mechanism may include in practice a cam driven by said command. Such a cam makes it possible to implement the change of direction, as well as possibly the reduction or overdrive of the movement, by the choice in particular of a suitable cam path.

La came définit par exemple un chemin de came apte à guider un pion solidaire du verrou ; on peut alors prévoir que le chemin de came comporte un renfoncement où le pion est immobilisé au moyen d'un ressort. L'association de la came et du ressort permet ainsi de verrouiller le mécanisme dans une position donnée.The cam defines for example a cam path capable of guiding a pin integral with the lock; it can then be provided that the cam path comprises a recess where the pin is immobilized by means of a spring. The combination of the cam and the spring thus makes it possible to lock the mechanism in a given position.

La première direction est par exemple essentiellement perpendiculaire à la seconde direction, ce qui offre une configuration particulièrement pratique, comme dans l'exemple décrit ci-après. On pourrait toutefois prévoir en variante que la première direction et la seconde direction forment entre elles un angle (non-nul) différent d'un angle droit.The first direction is for example substantially perpendicular to the second direction, which offers a particularly practical configuration, as in the example described below. However, it could alternatively be expected that the first direction and the second direction form between them an angle (non-zero) different from a right angle.

La commande peut être réalisée par une poignée. On peut alors prévoir un mécanisme de verrouillage automatique de la poignée (dans sa position correspondant à une position de connexion du verrou). Le verrouillage de la poignée se fait alors automatiquement (c'est-à-dire sans intervention de l'opérateur sur ce mécanisme de verrouillage, par exemple lorsque ce dernier amène la poignée dans une position où l'enceinte est connecté à l'autre enceinte au moyen du verrou) dès lors que les enceintes sont connectées ; son déverrouillage suppose en revanche une intervention spécifique de l'opérateur sur le mécanisme de verrouillage, comme expliqué ci-après, ce qui offre une sécurité supplémentaire.The control can be performed by a handle. One can then provide an automatic locking mechanism of the handle (in its position corresponding to a latch connection position). The locking of the handle is then done automatically (that is to say without intervention of the operator on this locking mechanism, for example when the latter brings the handle in a position where the speaker is connected to the other speaker with the lock) when the speakers are connected; unlocking however requires a specific intervention of the operator on the locking mechanism, as explained below, which provides additional security.

L'invention prévoit par ailleurs, éventuellement indépendamment de ce qui précède, une enceinte acoustique comprenant un dispositif de réglage d'un angle formé entre l'enceinte et une autre enceinte, caractérisée en ce qu'il comprend un élément dont la longueur en position de travail règle ledit angle et est déterminée en fonction de la position d'une pièce rotative, par exemple réglable par l'utilisateur, typiquement par rotation de la pièce rotative par l'utilisateur. L'utilisation d'une telle pièce rotative simplifie considérablement le réglage de la longueur de l'élément et par conséquent celui de l'angle inter-enceintes. L'utilisateur peut ainsi tourner la pièce rotative jusqu'à sa position souhaitée, qui détermine la longueur de l'élément en position de travail.The invention furthermore provides, optionally independently of the foregoing, an acoustic enclosure comprising a device for adjusting an angle formed between the enclosure and another enclosure, characterized in that it comprises an element whose length in position of work adjusts said angle and is determined according to the position of a rotating part, for example adjustable by the user, typically by rotation of the rotating part by the user. The use of such a rotating part greatly simplifies the adjustment of the length of the element and therefore that of the inter-enclosure angle. The user can thus turn the rotating part to its desired position, which determines the length of the element in the working position.

L'élément est par exemple un piston comprenant une tige montée à coulissement dans un corps et la pièce rotative peut alors être une roue montée à rotation autour d'un axe principal du piston.The element is for example a piston comprising a rod slidably mounted in a body and the rotating part can then be a wheel rotatably mounted about a main axis of the piston.

Comme expliqué plus loin, une enceinte sera alors par exemple solidaire du corps tandis que l'autre enceinte sera par exemple rattachée à la tige (éventuellement à l'aide d'une broche à bille) de telle sorte que le réglage de la longueur du piston dans sa position de travail permet de régler l'angle inter-enceintes.As explained below, an enclosure will for example be integral with the body while the other enclosure will for example be attached to the rod (possibly using a ball pin) so that the adjustment of the length of the piston in its working position adjusts the inter-speaker angle.

On peut prévoir par exemple que le piston soit en compression dans ladite position de travail, comme c'est le cas dans l'exemple de réalisation décrit ci-après.For example, the piston may be in compression in said working position, as is the case in the embodiment described hereinafter.

Selon une autre possibilité, le piston pourrait toutefois être en tension dans ladite position de travail, comme dans la variante présentée à la fin de la description qui suit.According to another possibility, the piston could however be in tension in said working position, as in the variant presented at the end of the description which follows.

On peut prévoir par ailleurs un dispositif de verrouillage de la tige dans une position maximale d'extension par rapport au corps, ce qui permet de superposer plusieurs enceintes sur un chariot pour leur transport en les maintenant à plat.In addition, it is possible to provide a device for locking the rod in a maximum position of extension relative to the body, which makes it possible to superpose several enclosures on a carriage for their transport by keeping them flat.

On peut également prévoir un dispositif de verrouillage de la tige dans une position rétractée dans le corps, ce qui permet le rangement du piston dans le corps, dans la hauteur de l'enceinte.One can also provide a locking device of the rod in a retracted position in the body, which allows the storage of the piston in the body, in the height of the enclosure.

Le réglage d'angle précité peut se faire autour d'un axe rétractable prévu dans l'enceinte pour connexion à l'autre enceinte.The aforementioned angle adjustment can be done around a retractable axis provided in the enclosure for connection to the other enclosure.

On peut prévoir dans ce cadre un mécanisme de conversion d'une commande en translation selon une première direction en un mouvement de translation d'au moins un premier verrou selon une seconde direction différente de la première direction, comme exposé plus haut. L'axe rétractable peut alors inclure ledit premier verrou.In this context, it is possible to provide a mechanism for converting a translation control in a first direction into a translation movement of at least one first latch in a second different direction. from the first direction, as explained above. The retractable shaft may then include said first latch.

Ce mécanisme de conversion peut éventuellement intégrer une ou plusieurs des caractéristiques optionnelles présentées ci-dessus pour le mécanisme de conversion proposé par l'invention.This conversion mechanism may optionally incorporate one or more of the optional features presented above for the conversion mechanism proposed by the invention.

Les figures 1 et 2 présentent une enceinte acoustique 2 qui comprend notamment les trois dispositifs, associés mécaniquement entre eux qui suivent :

  • un ensemble en « T » 4 logé sous l'enceinte et qui comprend un mécanisme qui convertit un mouvement de translation dans la profondeur d'une poignée 6 disposée à l'arrière de l'enceinte en mouvements latéraux entraînant chacun un verrou latéral (référencé 5 en figure 3) ;
  • un piston 8, ici unique, qui assure la connexion arrière à une autre enceinte, ainsi que les réglages d'angle entre l'enceinte 2 et cette autre enceinte : la partie supérieure du piston est captive de l'enceinte, la partie inférieure se raccorde à l'enceinte inférieure par une broche à bille unique. Une roue crantée 10, montée en rotation autour de l'axe du piston 8 et dont la position est par exemple repérée par des lettres, permet le préréglage de la longueur du piston (une fois les enceintes assemblées comme expliqué plus loin) et donc de l'angle inter-enceintes ;
  • un cadre métallique 12 qui assure la rigidité de l'ensemble : continuité métallique haut-bas (pour les forces de gravité en jeu sur les angles faibles) et avant-arrière (pour les transferts de force en case d'angle important).
The Figures 1 and 2 have an acoustic enclosure 2 which comprises in particular the three devices, mechanically associated with each other which follow:
  • a set of "T" 4 housed under the enclosure and which comprises a mechanism that converts a translational movement in the depth of a handle 6 disposed at the rear of the enclosure in lateral movements each driving a lateral latch (referenced 5 in figure 3 );
  • a piston 8, here unique, which provides the rear connection to another enclosure, and the angle settings between the chamber 2 and the other enclosure: the upper part of the piston is captive of the enclosure, the lower part is connects to the bottom enclosure with a single ball pin. A toothed wheel 10, rotatably mounted about the axis of the piston 8 and whose position is for example marked by letters, allows the presetting of the length of the piston (once the assembled speakers as explained below) and therefore of the inter-enclosure angle;
  • a metal frame 12 which ensures the rigidity of the assembly: high-low metal continuity (for the gravity forces at play on the weak angles) and front-back (for the transfers of force in case of important angle).

En dehors de ces ensembles structurels, l'enceinte 2 comprend des parois externes, à savoir notamment une paroi supérieure 14, une paroi inférieure 20, des parois latérales 22, une paroi arrière 24 configurée pour recevoir, dans un renfoncement de cette paroi, le piston 8.Apart from these structural assemblies, the enclosure 2 comprises external walls, namely in particular an upper wall 14, a bottom wall 20, side walls 22, a rear wall 24 configured to receive, in a recess of this wall, the piston 8.

La face avant de l'enceinte 2 est quant à elle fermée par une grille 26 afin de permettre l'émission des ondes acoustiques.The front face of the chamber 2 is in turn closed by a gate 26 to allow the emission of acoustic waves.

La paroi supérieure 14 comprend une partie avant 18 essentiellement plane et une partie arrière 16 essentiellement plane et légèrement inclinée par rapport à la partie avant 18.The upper wall 14 comprises a substantially planar front portion 18 and a rear portion 16 substantially flat and slightly inclined with respect to the front portion 18.

Dans l'exemple représenté, la partie avant 18 est quasiment horizontale (c'est-à-dire quasiment parallèle à la direction d'émission acoustique de l'enceinte), et la partie arrière 16 est inclinée suivant la demi-valeur maximale envisagée pour l'angle inter-enceintes.In the example shown, the front portion 18 is almost horizontal (that is to say almost parallel to the acoustic emission direction of the enclosure), and the rear portion 16 is inclined according to the maximum half-value envisaged for the inter-speaker angle.

Dans la région avant de la partie arrière 16 de la paroi supérieure 14, deux oreilles 28 dépassent de la paroi supérieure 14, les oreilles 28 étant situées chacune à une extrémité latérale de la paroi supérieure 14.In the front region of the rear portion 16 of the upper wall 14, two lugs 28 protrude from the upper wall 14, the lugs 28 being each located at a lateral end of the upper wall 14.

Comme expliqué également ci-après, les oreilles 28 sont issues du (c'est-à-dire liées mécaniquement au) cadre 12 et destinées à recevoir les verrous d'une autre enceinte conçue par exemple comme l'enceinte de la figure 1 et montée au contact de l'enceinte 2 au niveau d'une ligne d'articulation C qui s'étend entre les deux oreilles 28, précisément entre les centres des trous de oreilles 28. Les oreilles sont situées au niveau de la jonction entre la partie avant 18 et la partie arrière 16.As also explained below, the lugs 28 are derived from (that is to say mechanically linked to) the frame 12 and intended to receive the locks of another enclosure designed for example as the enclosure of the figure 1 and mounted in contact with the enclosure 2 at a hinge line C extending between the two ears 28, precisely between the centers of the earholes 28. The ears are located at the junction between the front portion 18 and rear portion 16.

La paroi inférieure 20 comprend également une partie avant 21, essentiellement plane (et ici quasiment horizontale), et une partie arrière 19, également essentiellement plane et légèrement inclinée par rapport à la partie avant 21 (là aussi dans le cas présent suivant la demi-valeur maximale envisagée pour l'angle inter-enceintes).The lower wall 20 also comprises a front part 21, essentially flat (and here almost horizontal), and a rear part 19, also substantially flat and slightly inclined with respect to the front part 21 (here also in the present case the half maximum value envisaged for the inter-enclosure angle).

L'ensemble en T 4 est monté sur l'enceinte 2, en particulier sur la partie arrière 19 de la paroi inférieure 20 de telle sorte qu'une surface inférieure de l'ensemble en T 4 s'étende dans le plan de la partie arrière 19 de la paroi inférieure 20, c'est-à-dire que l'ensemble en T ne dépasse pas de la surface définie par la partie arrière 19 de la paroi inférieure 20. On remarque que l'ensemble en T 4 (en particulier sa partie transversale 32 décrite ci-après) fait la jonction entre la partie avant 21 et la partie arrière 19).The T-piece 4 is mounted on the enclosure 2, in particular on the rear portion 19 of the bottom wall 20 so that a bottom surface of the T-piece 4 extends in the plane of the part rear 19 of the bottom wall 20, that is to say that the T-assembly does not exceed the surface defined by the rear portion 19 of the bottom wall 20. Note that the T-assembly 4 (in particular the transverse portion 32 described below) makes the junction between the front portion 21 and the rear portion 19).

Comme cela sera décrit plus en détail dans la suite, l'ensemble en T 4 comprend une partie axiale 30 et une partie transversale 32. La partie axiale 30 s'étend essentiellement dans la direction d'émission acoustique, bien que dans le plan de la partie arrière 19 de la paroi inférieure 20, entre la poignée 6 et la partie transversale 32.As will be described in more detail later, the T-piece 4 comprises an axial portion 30 and a transverse portion 32. The axial portion 30 extends substantially in the acoustic emission direction, although in the plane of the rear part 19 of the bottom wall 20, between the handle 6 and the transverse part 32.

On remarque que la poignée 6 s'étend ici de préférence au niveau de l'extrémité arrière de la paroi inférieure 20 de sorte qu'elle puisse être aisément manoeuvrée de l'arrière de l'enceinte.Note that the handle 6 preferably extends here at the rear end of the bottom wall 20 so that it can be easily operated from the rear of the enclosure.

La partie transversale 32 s'étend perpendiculairement à la partie axiale 30, quasiment sur toute la largeur de la partie arrière 19 de la paroi inférieure 20 et porte à chacune de ses extrémités un verrou amovible, comme expliqué dans la suite.The transverse portion 32 extends perpendicular to the axial portion 30, almost over the entire width of the rear portion 19 of the bottom wall 20 and carries at each of its ends a removable lock, as explained below.

L'ensemble en T 4 est par ailleurs situé au niveau de la paroi inférieure 20 de telle sorte que chacune des extrémités de sa partie transversale 32 portant les verrous 5 se situe au niveau de deux pattes parallèles 34, 36 issues du cadre 12.The T-piece 4 is also situated at the level of the bottom wall 20 so that each of the ends of its transverse part 32 carrying the bolts 5 is at the level of two parallel tabs 34, 36 coming from the frame 12.

Chaque patte 34, 36 porte un orifice 38 dans lequel peut venir se loger le verrou 5 voisin (porté par la partie transversale 32 de l'ensemble en T 4) en position sortie.Each lug 34, 36 carries an orifice 38 in which can be housed the neighboring latch 5 (carried by the transverse portion 32 of the assembly T 4) in the extended position.

La figure 3 illustre la connexion entre deux enceintes au moyen des pattes 34, 36 et de l'ensemble en T 4 d'une enceinte, et de l'oreille 28' d'une autre enceinte.The figure 3 illustrates the connection between two speakers by means of the tabs 34, 36 and the T-assembly 4 of an enclosure, and the ear 28 'of another enclosure.

On voit sur la figure 3 que, une fois les deux enceintes disposées l'une au contact de l'autre (c'est-à-dire lorsque la ligne d'articulation C de l'une des enceintes est disposée au droit de la partie transversale 32 de l'ensemble en T 4 de l'autre enceinte), l'orifice de l'oreille 28' est situé au droit de chacun des orifices 38 des pattes 34, 36 de l'autre enceinte de telle sorte que le verrou 5 peut alors être déplacé (comme expliqué ci-après) en position sortie, où il se trouve au niveau des orifices 38 de sa propre enceinte, et par conséquent traverse l'orifice de l'oreille 28'.We see on the figure 3 that, once the two speakers arranged one in contact with the other (that is to say when the hinge line C of one of the speakers is arranged to the right of the transverse portion 32 of the T-piece 4 of the other enclosure), the orifice of the ear 28 'is located at the right of each of the orifices 38 of the tabs 34, 36 of the other enclosure so that the lock 5 can then be moved (as explained below) in the out position, where it is located at the openings 38 of its own enclosure, and therefore crosses the orifice of the ear 28 '.

Un tel assemblage est réalisé à chaque extrémité latérale de l'assemblage des deux enceintes de telle sorte que celles-ci sont reliées l'une à l'autre au niveau d'un axe, ici l'axe reliant les deux verrous 5 (défini ci-dessus comme ligne d'articulation C).Such an assembly is made at each lateral end of the assembly of the two enclosures so that they are connected to one another at an axis, here the axis connecting the two locks 5 (defined above as hinge line C).

La figure 4 représente le cadre nu (c'est-à-dire sans les parois de l'enceinte), sur lequel est monté le piston 8.The figure 4 represents the bare frame (that is to say without the walls of the enclosure), on which is mounted the piston 8.

Le cadre 12 comprend une traverse principale 40 qui porte, en son centre, un support 42 destiné à porter à rotation la partie supérieure du piston 8.The frame 12 comprises a main cross member 40 which carries, in its center, a support 42 intended to rotate the upper part of the piston 8.

La traverse 40 est montée à chacune de ses extrémités à une partie latérale 44 du cadre 12.The crosspiece 40 is mounted at each of its ends to a lateral portion 44 of the frame 12.

Chaque partie latérale 44 s'étend essentiellement dans un plan, qui correspond de manière générale à celui de la paroi latérale 22 correspondante et est donc essentiellement perpendiculaire à la direction générale de la traverse 40.Each lateral portion 44 extends essentially in a plane, which corresponds generally to that of the corresponding lateral wall 22 and is therefore essentially perpendicular to the general direction of the crosspiece 40.

Chaque partie latérale 44 du cadre 12 comprend une structure triangulaire 46, qui reçoit à un sommet du triangle formé par celle-ci des fixations de la traverse 40 et dont le côté 50 opposé au sommet 48 relie mécaniquement l'oreille 28 aux pattes 34, 36 déjà mentionnées.Each lateral portion 44 of the frame 12 comprises a triangular structure 46, which receives, at a vertex of the triangle formed by it, fastenings of the crossmember 40 and whose side 50 opposite the vertex 48 mechanically connects the lug 28 to the lugs 34, 36 already mentioned.

Du fait de sa situation entre des ensembles de connexion inter-enceintes (oreille 28, pattes 34, 36 comme expliqué ci-dessus), on peut prévoir que cette partie 50 de la structure triangulaire 46 soit renforcée, par exemple en la réalisant sous forme de deux montants parallèles, comme visible en figure 4.Due to its location between inter-speaker connection assemblies (ear 28, tabs 34, 36 as explained above), it can be provided that this portion 50 of the triangular structure 46 is reinforced, for example by realizing it in form. of two parallel uprights, as visible in figure 4 .

Les figures 5 et 6 représentent en coupe le mécanisme de tringlerie de l'ensemble en T 4 qui permet de transformer, comme déjà indiqué, le mouvement de la poignée 6 dans le sens de la profondeur de l'enceinte (c'est-à-dire selon la direction générale d'émission de celle-ci), en un mouvement latéral pour chaque verrou 5, c'est-à-dire ici précisément un mouvement perpendiculaire au déplacement de la poignée 6 dans le plan de l'ensemble en T 4 (c'est-à-dire comme déjà indiqué le plan formé par la partie arrière de la paroi inférieure 20 de l'enceinte 2).The Figures 5 and 6 represent in section the linkage mechanism of the assembly T 4 which can transform, as already indicated, the movement of the handle 6 in the direction of the depth of the enclosure (that is to say, in the direction general emission thereof), in a lateral movement for each latch 5, that is to say here precisely a movement perpendicular to the movement of the handle 6 in the plane of the assembly T 4 (c ' that is to say as already indicated the plane formed by the rear part of the lower wall 20 of the enclosure 2).

La figure 5 représente ce mécanisme lorsque la poignée 6 est située dans sa position la plus en arrière et que chacun des verrous 5 est donc rétracté, tandis que la figure 6 représente le mécanisme lorsque la poignée 6 est dans sa position la plus en avant et que les verrous 5 sont donc complètement sortis et peuvent donc verrouiller l'assemblage de deux enceintes, comme expliqué ci-dessus en référence à la figure 3.The figure 5 represents this mechanism when the handle 6 is located in its rearmost position and each of the locks 5 is retracted, while the figure 6 represents the mechanism when the handle 6 is in its most forward position and that the locks 5 are fully extended and can therefore lock the assembly of two speakers, as explained above with reference to the figure 3 .

Ce mécanisme comprend une tringle axiale 54 située entre la poignée 6 et une came 60, et guidée en translation le long de son propre axe par des paliers 62.This mechanism comprises an axial rod 54 located between the handle 6 and a cam 60, and guided in translation along its own axis by bearings 62.

La tringle 54 axiale permet ainsi d'entraîner la came 60 (décrite en détail ci-après) dans un mouvement de translation identique à celui que l'utilisateur fait subir à la poignée 6.The axial rod 54 thus makes it possible to drive the cam 60 (described in detail below) in a translational movement identical to that which the user makes to the handle 6.

Le mécanisme comprend également deux tringles transversales 56, 58 qui relient chacune la came 60 à un verrou 5. Chaque tringle transversale 56, 58 est guidée en translation au moyen de paliers 64 dans la direction de mouvements des verrous 5, c'est-à-dire ici une direction perpendiculaire à la tringle axiale 54.The mechanism also comprises two transverse rods 56, 58 which each connect the cam 60 to a latch 5. Each transverse rod 56, 58 is guided in translation by means of bearings 64 in the direction of movement of the latches 5, that is to say here we mean a direction perpendicular to the axial rod 54.

Un ressort 66 est par ailleurs monté sur chaque tringle transversale 56, 58, entre la came 60 et le palier 64.A spring 66 is also mounted on each transverse rod 56, 58, between the cam 60 and the bearing 64.

La came 60 comporte deux chemins de came 68 qui coopèrent chacun avec un pion 70 solidaire d'une tringle transversale 56, 58. Chaque chemin de came 68 comporte une première partie formée d'un pan incliné, ici à 45°, et une seconde partie présentant un léger renfoncement dans la direction de rétractation de la tringle latérale 56, 58 correspondante.The cam 60 comprises two cam tracks 68 which each cooperate with a pin 70 integral with a transverse rod 56, 58. Each cam path 68 comprises a first portion formed of an inclined face, here at 45 °, and a second part with a slight recess in the direction of retraction of the corresponding side rod 56, 58.

Comme déjà indiqué, la figure 5 représente le mécanisme dans sa position où chacun des verrous 5 est rétracté (c'est-à-dire rentré) dans l'ensemble en T 4.As already indicated, the figure 5 represents the mechanism in its position where each of the latches 5 is retracted (i.e. retracted) into the T 4 assembly.

L'utilisateur enfonce alors la poignée selon la flèche U indiquée en figure 5, ce qui entraîne le déplacement de la tringle axiale 56, et donc de la came 60, en translation selon ce même sens.The user then pushes the handle according to the arrow U indicated in figure 5 , which causes the displacement of the axial rod 56, and therefore of the cam 60, in translation in the same direction.

Ce mouvement de la came 60 provoque, du fait du déplacement des pions 70 dans les chemins de came 60 (en particulier ici les pans à 45°), le mouvement des pions 70 et donc des tringles transversales 56, 58 dans l'axe de ces tringles et pour chacune vers l'extérieur, c'est-à-dire dans le sens d'une sortie des verrous 5 de l'ensemble en T 4.This movement of the cam 60 causes, because of the displacement of the pins 70 in the cam tracks 60 (in particular here the 45 ° sections), the movement of the pins 70 and thus transverse rods 56, 58 in the axis of these rods and for each outwardly, that is to say in the direction of an output of the latches 5 of the T-assembly 4.

On remarque que ce mouvement s'accompagne de la mise en compression des ressorts 66.It is noted that this movement is accompanied by the compression of the springs 66.

Le mouvement se poursuit jusqu'à ce que le pion 70 arrive au niveau de la partie du chemin de came 68 formant renfoncement, où le pion 70 s'immobilisera sous l'effet de la compression du ressort 66 (qui tend à maintenir le pion 70 dans le renfoncement), comme représenté dans la vue de détail de la figure 7B.The movement continues until the pin 70 arrives at the portion of the recessing cam path 68, where the pin 70 will stop under the effect of the compression of the spring 66 (which tends to hold the pin 70 in the recess), as shown in the detail view of the Figure 7B .

On atteint ainsi la position sortie des verrous 5, représentée en figure 6. Cette position est stable du fait de l'immobilisation des pions 70 dans les renfoncements.This achieves the exit position of the locks 5, represented in FIG. figure 6 . This position is stable due to the immobilization of the pins 70 in the recesses.

Afin de fournir une sécurité supplémentaire, on utilise ici un mécanisme de verrouillage de la poignée 6 dans sa position correspondant à la position sortie des verrous 5. Ce mécanisme est visible sur la figure 7A.In order to provide additional security, a locking mechanism of the handle 6 is used here in its position corresponding to the extended position of the latches 5. This mechanism is visible on the Figure 7A .

Ce mécanisme comprend une tige 104 guidée par une entretoise 108 et maintenue au contact de la poignée 6 (c'est-à-dire ici vers le bas) par un ressort 102.This mechanism comprises a rod 104 guided by a spacer 108 and held in contact with the handle 6 (that is to say here downwards) by a spring 102.

La partie supérieure de la tige 104 porte un dispositif de préhension 106.The upper part of the rod 104 carries a gripping device 106.

Dans sa position illustrée en figure 7A (qui correspond à la position avant de la poignée 6 et donc à la position rentrée des verrous), la partie inférieure de la tige 104 vient en appui sur la face supérieure de la poignée 6.In its position illustrated in Figure 7A (Which corresponds to the front position of the handle 6 and thus to the retracted position of the locks), the lower part of the rod 104 comes to rest on the upper face of the handle 6.

Lorsque la poignée 6 est poussée vers l'avant pour atteindre la position sortie des verrous 5 comme expliqué ci-dessus, la tige s'aligne avec un trou 110 prévu dans la poignée 6 et s'insère automatiquement dans ce trou 110, bloquant ainsi la poignée 6 dans sa position avant.When the handle 6 is pushed forward to reach the extended position of the locks 5 as explained above, the rod is aligned with a hole 110 provided in the handle 6 and automatically inserted into the hole 110, thereby blocking the handle 6 in its forward position.

Le retour de la poignée 6 dans sa position arrière nécessite en revanche, outre l'application d'une force à l'encontre des ressorts 66 comme déjà expliqué, que l'utilisateur soulève la tige 104 (au moyen du dispositif de préhension 106) afin d'extraire celle-ci du trou 110 et ainsi déverrouiller la poignée 6.The return of the handle 6 in its rear position requires, in addition to the application of a force against the springs 66 as already explained, that the user raises the rod 104 (by means of the gripping 106) to extract it from the hole 110 and thus unlock the handle 6.

On rappelle que, comme déjà exposé en référence à la figure 3, les verrous 5 permettent, en position sortie, le verrouillage de deux enceintes et la définition d'un axe de rotation entre ces enceintes, qui correspond à l'axe reliant les verrous 5.It is recalled that, as already stated with reference to the figure 3 , the locks 5 allow, in the extended position, the locking of two speakers and the definition of an axis of rotation between these speakers, which corresponds to the axis connecting the locks 5.

On remarque enfin que l'effort de maintien des pions 70 dans les renfoncements des chemins de came 68 est dimensionné de façon à rendre possible la sortie des pions 70 les renfoncements correspondants lorsque l'utilisateur manoeuvre la poignée 6 vers l'arrière (c'est-à-dire pour revenir de la position représentée en figure 6 à la position représentée en figure 5).Note finally that the effort of holding the pins 70 in the recesses of the cam tracks 68 is dimensioned so as to make it possible for the pins 70 to leave the corresponding recesses when the user moves the handle 6 towards the rear (c '). that is, to return from the position represented in figure 6 at the position represented in figure 5 ).

Les figures 8 et 9 représentent le piston 8 en position de réglage ou position de transport, qui correspond à la position d'extension maximale du piston.The Figures 8 and 9 represent the piston 8 in the adjustment position or transport position, which corresponds to the maximum extension position of the piston.

Le piston 8 comprend une attache supérieure 72 et une attache inférieure 74.The piston 8 comprises an upper attachment 72 and a lower attachment 74.

L'attache supérieure 72 est solidaire du corps 78 du piston ; l'attache supérieure 72 est ici réalisée d'une pièce avec un carter 76 entourant le corps 78 et solidaire de celui-ci.The upper attachment 72 is integral with the body 78 of the piston; the upper attachment 72 is here made in one piece with a housing 76 surrounding the body 78 and secured thereto.

Le corps 78 forme la partie femelle du piston 8, tandis que la partie mâle est formée par une tige 80 montée à coulissement dans le corps 78 et qui porte l'attache inférieure 74.The body 78 forms the female part of the piston 8, while the male part is formed by a rod 80 slidably mounted in the body 78 and which carries the lower fastener 74.

Une manette 82 est montée sur une paroi latérale du carter 76 et comprend un verrou 86, monté à coulissement selon une direction perpendiculaire à l'axe du piston 8 et constamment entraîné vers l'axe de celui-ci au moyen d'un ressort 84 monté dans la manette 82.A handle 82 is mounted on a side wall of the housing 76 and comprises a latch 86, slidably mounted in a direction perpendicular to the axis of the piston 8 and constantly driven towards the axis thereof by means of a spring 84 mounted in the handle 82.

On remarque que le verrou 86 est monté à coulissement non seulement à travers une ouverture adaptée du carter (à laquelle est montée la manette 82) mais également à travers un alésage cylindrique 79 formé dans le corps 78.Note that the latch 86 is slidably mounted not only through a suitable opening of the housing (to which the handle 82 is mounted) but also through a cylindrical bore 79 formed in the body 78.

L'utilisateur peut, en agissant à l'encontre de l'effort généré par le ressort 84, manoeuvrer le verrou 86 dans diverses positions selon son axe comme expliqué ci-après.The user can, acting against the force generated by the spring 84, operate the latch 86 in various positions along its axis as explained below.

Dans la position représentée sur les figures 8 et 9, le verrou 86 (sous l'effet du ressort 84) pénètre dans un évidement circonférentiel 88 formé sur la circonférence de la tige 80 dans sa partie supérieure (c'est-à-dire sa partie située du côté de l'attache supérieure 72).In the position shown on the Figures 8 and 9 , the latch 86 (under the effect of the spring 84) penetrates a circumferential recess 88 formed on the circumference of the rod 80 in its upper part (that is to say, its part located on the side of the upper attachment 72 ).

La tige 80 est ainsi dans une position longitudinale prédéfinie par rapport au corps 78, déterminée par le positionnement relatif du verrou 86 et de l'évidement circonférentiel 88. Du fait que l'évidement circonférentiel 88 est situé dans la partie supérieure de la tige 80, cette position correspond à l'extension maximale utilisée du piston 8.The rod 80 is thus in a predefined longitudinal position relative to the body 78, determined by the relative positioning of the lock 86 and the circumferential recess 88. Because the circumferential recess 88 is located in the upper part of the rod 80 this position corresponds to the maximum extension used of the piston 8.

Dans cette position, l'utilisateur peut tourner la roue crantée 10, solidaire de la tige 80 (notamment en rotation autour de l'axe du piston 8) jusqu'à une position souhaitée, par exemple repéré par une lettre donnée.In this position, the user can turn the toothed wheel 10, integral with the rod 80 (in particular in rotation about the axis of the piston 8) to a desired position, for example identified by a given letter.

Ce faisant, l'utilisateur règle la position angulaire de la tige 80 autour de son axe, et donc notamment par rapport au corps 78 (fixe en rotation par rapport à l'enceinte). On remarque à cet égard que la tige 80 et la roue crantée 10, solidaires l'une de l'autre, sont mobiles en rotation par rapport à l'attache inférieure 74.In doing so, the user sets the angular position of the rod 80 about its axis, and therefore in particular with respect to the body 78 (fixed in rotation relative to the enclosure). Note in this regard that the rod 80 and the toothed wheel 10, integral with each other, are rotatable relative to the lower fastener 74.

En partant de la position représentée en figure 9, l'utilisateur peut tirer sur la manette 82 afin de faire ressortir le verrou 86 de l'évidement 88, ce qui libère la translation de la tige 80 dans le corps 78.Starting from the position represented in figure 9 , the user can pull the handle 82 to bring out the lock 86 of the recess 88, which releases the translation of the rod 80 in the body 78.

Ce mouvement est possible jusqu'à ce qu'un pion 90 porté par la tige 80 vienne coopérer avec une surface d'un profilé 92 prévu sur le corps 78, comme expliqué plus en détail à présent.This movement is possible until a pin 90 carried by the rod 80 comes to cooperate with a surface of a profile 92 provided on the body 78, as explained in more detail now.

La longueur du piston en compression est déterminée (lors du mouvement de compression du piston après assemblage des enceintes comme expliqué dans la suite) par la position longitudinale à laquelle le pion 90 de la tige 80 vient en butée sur le profilé 92 porté par le corps 78, comme par exemple dans sa position représentée sur le figures 11 et 12.The length of the piston in compression is determined (during the compression movement of the piston after assembly of the speakers as explained below) by the longitudinal position at which the pin 90 of the rod 80 abuts on the profile 92 carried by the body. 78, as for example in its position represented on the Figures 11 and 12 .

Du fait de la forme particulière du profilé 92 (voir en particulier la vue en perspective du corps 78 en figure 13 ), la position longitudinale de la tige 80 à laquelle le pion vient en butée sur le profilé 92 dépend de la position angulaire relative du corps 78 et de la tige 80, position qui a été réglée au préalable par l'utilisateur comme expliqué ci-dessus en référence notamment aux figures 8 et 9.Due to the particular shape of the profile 92 (see in particular the perspective view of the body 78 in figure 13 ), the longitudinal position of the rod 80 to which the pin abuts on the profile 92 depends on the relative angular position of the body 78 and the rod 80, position which has been previously set by the user as explained above. above with reference in particular to Figures 8 and 9 .

La figure 14 représente le piston 8 dans une position rétractée (ou de rangement) dans laquelle il occupe un volume minimum, comme d'ailleurs représenté sur les figures 1 et 2.The figure 14 represents the piston 8 in a retracted position (or storage) in which it occupies a minimum volume, as also represented on the Figures 1 and 2 .

La tige 80 comprend un alésage cylindrique 94 (d'axe perpendiculaire à l'axe principal de la tige 80) qui se trouve, lorsque la tige 80 est complètement rentrée dans le corps 78 et dans une position angulaire particulière de la tige 80 par rapport au corps 78, au droit de l'alésage cylindrique 79 traversé par le verrou 86 comme déjà expliqué.The rod 80 comprises a cylindrical bore 94 (of axis perpendicular to the main axis of the rod 80) which is, when the rod 80 is fully retracted into the body 78 and in a particular angular position of the rod 80 relative to to the body 78, to the right of the cylindrical bore 79 traversed by the latch 86 as already explained.

Ainsi, lorsque l'utilisateur positionne la roue crantée 10 dans une position adaptée, par exemple dument repérée à cet effet, et enfonce la tige 80 dans le corps 78 (par exemple en saisissant l'attache inférieure 74 et en la soulevant), le verrou 86 entre dans l'alésage cylindrique 94 de la tige 80 sous la pression du ressort 84 et vient ainsi immobiliser longitudinalement la tige 80 dans le corps 78, ce qui définit la position fixe rétractée mentionnée ci-dessus.Thus, when the user positions the toothed wheel 10 in a suitable position, for example duly marked for this purpose, and pushes the rod 80 into the body 78 (for example by grasping the lower fastener 74 and lifting it), the lock 86 enters the cylindrical bore 94 of the rod 80 under the pressure of the spring 84 and thus immobilizes longitudinally the rod 80 in the body 78, which defines the retracted fixed position mentioned above.

On va à présent décrite une procédure d'accrochage d'un ensemble d'enceintes conforme aux enseignements de l'invention.We will now describe a procedure for attaching a set of speakers according to the teachings of the invention.

La figure 15 représente une première enceinte E1 raccordée à son cadre (ou « bumper »), lui-même raccordé à deux moteurs de levage.The figure 15 represents a first enclosure E1 connected to its frame (or " bumper "), itself connected to two lifting motors.

Les figures 16 et 17 montrent comment une seconde enceinte E2 est connectée à la première enceinte E1.The figures 16 and 17 show how a second speaker E2 is connected to the first speaker E1.

La procédure d'assemblage de ces deux enceintes est par exemple la suivante :

  • on prépare la première enceinte E1 en positionnant le piston 8' de cette enceinte dans sa position de réglage (visible sur les figures 8 et 9) et en réglant sa roue crantée 10' sur la position choisie ;
  • on retire la broche à bille 73" montée sur l'attache supérieure 72" du piston 8" de la seconde enceinte E2 ;
  • on positionne la seconde enceinte E2 sous la première enceinte E1 en les alignant comme déjà indiqué (c'est-à-dire en alignant l'axe d'articulation C de la seconde enceinte E2 avec l'axe des verrous de la première enceinte E1);
  • on déplace vers l'avant la poignée 6' du mécanisme de connexion de la première enceinte E1, ce qui permet de lier les enceintes E1, E2 comme déjà expliqué en référence à la figure 3 ;
  • on monte la broche à bille 73" à travers l'attache supérieure 72" du piston 8" de la seconde enceinte E2 et à travers l'attache inférieure 74' du piston 8' de la première enceinte E1.
The assembly procedure of these two enclosures is for example the following:
  • the first chamber E1 is prepared by positioning the piston 8 'of this chamber in its adjustment position (visible on the Figures 8 and 9 ) and by adjusting its toothed wheel 10 'to the chosen position;
  • removing the ball pin 73 "mounted on the upper attachment 72" of the piston 8 "of the second enclosure E2;
  • positioning the second enclosure E2 under the first enclosure E1 by aligning them as already indicated (that is to say by aligning the articulation axis C of the second enclosure E2 with the axis of the locks of the first enclosure E1 );
  • the handle 6 'of the connection mechanism of the first enclosure E1 is moved forward, which makes it possible to link the enclosures E1, E2 as already explained with reference to FIG. figure 3 ;
  • the ball pin 73 "is mounted through the upper fastener 72" of the piston 8 "of the second chamber E2 and through the lower fastener 74 'of the piston 8' of the first chamber E1.

On soulève le nouvel ensemble ainsi constitué au moyen des moteurs de levage, comme visible sur la figure 18 , afin de recevoir l'enceinte suivante.The new assembly thus constituted is raised by means of the lifting motors, as visible on the figure 18 , in order to receive the next speaker.

On répète ce processus pour chacune des enceintes à ajouter de sorte que l'on obtient une pluralité d'enceintes assemblées comme visible en figure 19 . This process is repeated for each of the speakers to be added so that a plurality of assembled speakers are obtained as visible in figure 19 .

Le moteur arrière de levage, connecté à la dernière enceinte de la pluralité (c'est-à-dire l'enceinte la plus basse), vient assurer la mise en compression de l'ensemble de sorte que les pistons sont mis en compression, atteignant ainsi leur position de travail, et les angles entre enceintes prennent leurs valeurs définitives, déterminées par le réglage des roues crantées, comme représenté en figure 20 . The rear lift motor, connected to the last speaker of the plurality (that is to say the lowest speaker), ensures the compression of the assembly so that the pistons are put in compression, reaching their working position, and the angles between the speakers take their final values, determined by the adjustment of the toothed wheels, as represented in FIG. figure 20 .

On peut alors lever le système à hauteur définitive.We can then lift the system to final height.

On remarque que ce mode d'accrochage dit en « compression » présente l'avantage de ne pas avoir à soulever l'arrière des enceintes successives pour régler les angles : les enceintes montent verticalement, et ce sont les moteurs de levage qui donnent à l'assemblage sa configuration définitive.Note that this mode of attachment called " compression " has the advantage of not having to lift the rear of the successive speakers to adjust the angles: the speakers rise vertically, and it is the lifting motors that give the assembly its final configuration.

La procédure de démontage se fait à l'inverse de la procédure de montage à la différence que la déconnexion des enceintes suppose une action spécifique de l'opérateur sur le mécanisme de verrouillage, comme expliqué ci-dessus.The disassembly procedure is the opposite of the editing procedure except that disconnecting the speakers requires action. specific to the operator on the locking mechanism, as explained above.

Le système de réglage d'angle proposé par l'invention est toutefois également applicable lorsque l'on utilise un mode d'accrochage en tension. On utilisera toutefois dans ce cas un piston tel que représenté sur les figures 21 et 22 dans lesquels la position angulaire de la tige (réglée grâce à une roue crantée comme précédemment) détermine la longueur du piston en extension (et non en compression comme dans l'exemple décrit ci-dessus).The angle adjustment system proposed by the invention is however also applicable when using a mode of attachment in tension. However, in this case a piston as shown in Figures 21 and 22 in which the angular position of the rod (adjusted by a notched wheel as above) determines the length of the piston in extension (and not in compression as in the example described above).

Les exemples présentés ci-dessus ne sont d'ailleurs que des modes de réalisation possibles de l'invention, qui ne s'y limite pas.The examples presented above are, moreover, only possible embodiments of the invention, which is not limited thereto.
