Description

L'invention concerne, en premier lieu un panneau en matière plastique thermosoudable, pouvant servir notamment comme volet ou élément de porte, comportant un cadre constitué d'éléments rectilignes ménageant un évidement, rempli au moins partiellement par des lames, également rectilignes, s'étendant entre deux éléments parallèles opposés du cadre, les organes d'assemblage des deux éléments opposés du cadre et des lames étant constitués par une première languette rectiligne rigidement associée à chaque élément, saillant du champ intérieur de celui-ci et s'engageant dans des rainures pratiquées dans les faces extrêmes des lames transversalement à celles-ci.The invention relates, first of all, to a panel of heat-sealable plastic material, which can serve in particular as a shutter or door element, comprising a frame made up of rectilinear elements providing a recess, at least partially filled with blades, also rectilinear, extending between two opposite parallel elements of the frame, the assembling members of the two opposite elements of the frame and the blades being constituted by a first rectilinear tongue rigidly associated with each element, projecting from the internal field thereof and engaging in grooves made in the end faces of the blades transversely to them.

L'invention concerne aussi le procédé d'assemblage des lames et des éléments d'un tel panneau ainsi que la machine utilisée pour la mise en oeuvre de ce procédé.The invention also relates to the method of assembling the blades and elements of such a panel as well as the machine used for the implementation of this method.

On connaît déjà des panneaux en matière plastique thermosoudable comportant un cadre et des lames de remplissage, pouvant servir notamment comme volet ou éléments de porte. Un tel panneau connu comporte un cadre comprenant deux montants verticaux réunis rigidement entre eux par deux traverses horizontales et parallèles et, d'autre part, des lames de remplissage horizontales assemblées aux montants verticaux du cadre par des organes d'assemblage mécaniques du type à tenon et mortaise. Ainsi, par exemple, chaque lame de remplissage est pourvue, à ses deux parties extrêmes libres, d'une rainure ou saillie verticale coopérant avec une saillie ou rainure verticale correspondante du montant du cadre (voir FR - A - 2.293.568).Panels of heat-sealable plastic are already known comprising a frame and filling blades, which can serve in particular as a shutter or door elements. Such a known panel comprises a frame comprising two vertical uprights rigidly joined together by two horizontal and parallel crosspieces and, on the other hand, horizontal filling blades assembled to the vertical uprights of the frame by mechanical assembly members of the tenon type and mortise. Thus, for example, each filling blade is provided, at its two free end parts, with a vertical groove or projection cooperating with a corresponding vertical projection or groove in the amount of the frame (see FR - A - 2.293.568).

On connaît aussi (voir FR - A - 2.040.047) une porte à persienne du même type général que cité précédemment dont les organes d'assemblage des lames et des montants verticaux comportent un élément rapporté intermédiaire rigidement solidaire de chaque montant pourvu d'une unique petite nervure longitudinale décalée vers l'une des ailes de l'élément rapporté venant se verrouiller dans une encoche prévue initialement dans l'extrémité des lames.There is also known (see FR - A - 2.040.047) a louver door of the same general type as mentioned above, the assembly members of the blades and the vertical uprights comprising an intermediate insert rigidly secured to each upright provided with a single small longitudinal rib shifted towards one of the wings of the insert coming to lock in a notch provided initially in the end of the blades.

Ces panneaux connus présentent cependant de nombreux inconvénients: les lames ne constituent pas des éléments de résistance du panneau mais uniquement des moyens de remplissage du cadre. Le maintien des lames est douteux du fait des moyens d'assemblage utilisés. Ainsi, de façon générale, le panneau manque de rigidité et est susceptible de se déformer à l'usage.These known panels however have many drawbacks: the blades do not constitute elements of resistance of the panel but only means for filling the frame. The maintenance of the blades is doubtful because of the assembly means used. Thus, in general, the panel lacks rigidity and is liable to deform during use.

L'utilisation d'un système d'assemblage mécanique du type à tenon et mortaise, tel que selon le FR - A - 2 293 568 suppose des tolérances dimensionnelles très précises.The use of a mechanical assembly system of the tenon and mortise type, such as according to FR - A - 2 293 568 assumes very precise dimensional tolerances.

Le panneau tel que décrit dans le FR - A - 2 040 047 ne permet pas d'atteindre un assemblage suffisamment rigide des lames avec les montants.The panel as described in FR - A - 2 040 047 does not allow a sufficiently rigid assembly of the blades with the uprights.

Le but de l'invention est de pallier aux inconvénients mentionnés ci-dessus. La solution à ce problème consiste à réaliser un panneau selon le FR-A-2040047 dans lequel lesdits organes d'assemblage des deux 'éléments du cadre et des lames en outre au moins une §econde languette analogue à la première coopérant avec au moins une seconde rainure de la même manière que la languette avec la rainure et que les languettes sont associées rigidement à chacune des rainures correspondantes par soudage du matériau pour assurer l'assemblage des lames avec les éléments. Les lames remplissent éventuellement en totalité l'évidement du cadre, en le rendant ainsi complètement fermé.The object of the invention is to overcome the drawbacks mentioned above. The solution to this problem consists in producing a panel according to FR-A-2040047 wherein said connecting elements of the two elements of the framework and further at least one blade § econde like tongue to the first cooperating with at least one second groove in the same way as the tongue with the groove and that the tongues are rigidly associated with each of the corresponding grooves by welding the material to ensure the assembly of the blades with the elements. The blades may fill the entire recess of the frame, thereby making it completely closed.

Les avantages de l'invention sont que cet assemblage est tout à la fois très simple à réaliser et permet d'obtenir un panneau présentant une résistance élevée, donc non susceptible d'être déformé à l'usage. Ainsi l'invention permet de réaliser un panneau présentant une résistance à l'arrachement pouvant atteindre et même dépasser 30 kg en moyenne par panneau.The advantages of the invention are that this assembly is at the same time very simple to carry out and makes it possible to obtain a panel having a high resistance, therefore not liable to be deformed in use. Thus, the invention makes it possible to produce a panel having a tear resistance which can reach and even exceed 30 kg on average per panel.

Les lames peuvent avoir en section droite transversale toute forme désirée. Elles peuvent être soit écartées l'une de l'autre en laissant ainsi des jours variables entre elles, soit au contraire, jointives, assurant une parfaite fermeture de l'évidement du cadre.The blades can have any desired shape in cross section. They can either be separated from one another, thus leaving variable days between them, or on the contrary, contiguous, ensuring a perfect closure of the recess of the frame.

Les panneaux assemblés selon la présente invention présentant une rigidité élevée, peuvent être utilisés de façon polyvalente, non seulement comme volet mais aussi comme portail, bardage, etc.The panels assembled according to the present invention having a high rigidity, can be used in a versatile manner, not only as a shutter but also as a gate, cladding, etc.

Les soudures étant réalisées à l'intérieur des rainures, sans bavures apparentes à l'extérieur, sont donc invisibles de l'extérieur de sorte que le panneau est bien plus esthétique que ceux connus à ce jour.The welds being made inside the grooves, without visible burrs on the outside, are therefore invisible from the outside so that the panel is much more aesthetic than those known to date.

En ce qui concerne le procédé d'assemblage . proprement dit, il n'est pas nécessaire d'envisager une préparation spéciale des lames, hormis leur coupe à longueur. En particulier, aucune opération d'entaille ou similaire n'est nécessaire. Les problèmes de tolérance dimensionnelle sont donc éliminés.Regarding the assembly process. proper, it is not necessary to consider a special preparation of the blades, except their cut to length. In particular, no notch or similar operation is necessary. Dimensional tolerance problems are therefore eliminated.

L'assemblage suivant l'invention est tel qu'il permet d'éviter en particulier le faux equerrage qui se produit avec la plupart des autres moyens d'assemblage connus à ce jour. D'autre part, l'assemblage selon l'invention permet une parfaite tenue réciproque des lames et des montants. Il en résulte que l'on peut concevoir une fabrication simplifiée de panneaux dépourvus de traverse d'extrémité. Cette simplification est d'autant plus importante que l'assemblage des montants et des traverses constituant le cadre est du type à onglet.The assembly according to the invention is such that it makes it possible in particular to avoid the false squaring which occurs with most of the other assembly means known to date. On the other hand, the assembly according to the invention allows perfect reciprocal holding of the blades and the uprights. As a result, it is possible to conceive of a simplified manufacture of panels devoid of end crossmembers. This simplification is all the more important as the assembly of the uprights and crosspieces constituting the frame is of the tab type.

Enfin, la fabrication d'un panneau, par le procédé suivant l'invention, peut être rendue entièrement automatique.Finally, the manufacture of a panel, by the method according to the invention, can be made fully automatic.

Dans ce qui suit l'invention est exposée plus en détail à l'aide des dessins représentant seulement un mode d'exécution.In what follows, the invention is explained in more detail using the drawings showing only one embodiment.

La figure 1 est une vue schématique partielle, en perspective éclatée, d'un panneau pourvu de moyens d'assemblage selon l'invention; la figure 2 est une vue schématique, partielle, en coupe selon la ligne II-II de la figure 1; la figure 3 est une vue schématique partielle, analogue à la figure 2, d'une seconde forme d'exécution de l'invention; la figure 4 est une vue schématique, à plus petite échelle, de la machine pour la mise en oeuvre du procédé d'assemblage selon l'invention.Figure 1 is a partial schematic view, in exploded perspective, of a panel provided with assembly means according to the invention; Figure 2 is a schematic partial view in section along the line II-II of Figure 1; Figure 3 is a partial schematic view, similar to Figure 2, of a second embodiment of the invention; Figure 4 is a schematic view, on a smaller scale, of the machine for implementing the assembly method according to the invention.

Les moyens d'assemblage selon l'invention s'appliquent notamment et de manière non limitative aux panneaux de toutes sortes, en matière plastique thermosoudable, notamment en PVC.The assembly means according to the invention apply in particular and without limitation to panels of all kinds, made of heat-sealable plastic, in particular PVC.

Ce panneau comporte, de manière connue, un cadre constitué d'éléments 1 rectilignes formant les montants et les traverses du panneau, assemblés à équerre, ménageant un évidement rempli en totalité ou seulement en partie par des lames 2, également rectilignes, s'étendant entre deux éléments 1 parallèles et opposés. Ainsi, lorsque les lames 2 sont horizontales, elles s'étendent entre des éléments 1 ont, en section droite tranversale contraire, si les lames 2 sont verticales, elles s'étendant entre deux éléments 1 formant traverses horizontales et parallèles. Les éléments 1 ont, en section droite transversale une forme générale rectangulaire ou pseudo rectangulaire définissant un chant intérieur 3 de préférence plein, délimitant le bord de l'évidement limité par le cadre. Les deux chants 3 de deux éléments 1 parallèles entre eux se font face et sont destinés à l'assemblage par soudage avec les faces d'extrémité des lames 2.This panel comprises, in known manner, a frame made up of rectilinear elements 1 forming the uprights and the crosspieces of the panel, assembled at a square, providing a recess filled entirely or only partially by blades 2, also rectilinear, extending between two parallel and opposite elements 1. Thus, when the blades 2 are horizontal, they extend between elements 1 have, in opposite transverse cross-section, if the blades 2 are vertical, they extending between two elements 1 forming horizontal and parallel crosspieces. The elements 1 have, in cross-section, a generally rectangular or pseudo-rectangular shape defining an inner edge 3, preferably full, delimiting the edge of the recess limited by the frame. The two edges 3 of two elements 1 parallel to each other face each other and are intended for assembly by welding with the end faces of the blades 2.

Les lames 2 peuvent avoir, en section droite transversale, toute forme désirée en fonction notamment d'un aspect esthétique souhaité. La longueur des lames correspond à l'écartement entre les chants 3 se faisant face des deux éléments 1 auxquels elles sont rigidement associées. Le pas des lames peut être quelconque. Les lames peuvent être soit jointives soit, au contraire, espacées entre elles, en ménageant ainsi des jours.The blades 2 can have, in cross section, any desired shape depending in particular on a desired aesthetic appearance. The length of the blades corresponds to the spacing between the edges 3 facing the two elements 1 with which they are rigidly associated. The pitch of the blades can be arbitrary. The blades can be either contiguous or, on the contrary, spaced apart, thus saving days.

Les organes d'assemblage des éléments 1 et des lames 2, selon l'invention, sont localisés à chaque extrémité d'une lame 2 et sur l'élément 1 associé à cette extrémité. Par la suite, on ne se référera donc qu'à une seule des deux extrémités de chaque lame, étant entendu que les organes d'assemblage sont symétriquement placés en ce qui concerne l'autre extrémité.The assembling elements 1 and blades 2, according to the invention, are located at each end of a blade 2 and on the element 1 associated with this end. Thereafter, reference will therefore be made to only one of the two ends of each blade, it being understood that the assembly members are symmetrically placed with regard to the other end.

A l'élément 1 sont associées rigidement au moins deux languettes 4 et 4' saillant de la partie médiane du chant intérieur 3, allongées dans le sens de la longueur de l'élément 1 et, de préférence, par raison de symétrie non strictement nécessaire, parallèle aux arêtes définies par le chant 3 et les faces des côtes 5 et 6 de l'élément 1 et du panneau. Les languettes 4 sont soit d'une pièce avec l'élément 1 proprement dit, étant réalisées à la fabrication de celui-ci, soit, au contraire, rapportées. Au lieu de deux languettes 4 et 4', on peut prévoir un nombre plus élevé de languettes. Les languettes 4 et 4' sont soit continues, c'est-à-dire ininterrompues d'une extrémité à l'autre de l'élément 1, soit, au contraire, discontinues et comportant donc des interruptions. Cette dernière solution peut être adoptée notamment dans l'hypothèse de lames 2 non jointives.At the element 1 are rigidly associated at least two tabs 4 and 4 'projecting from the middle part of the inner edge 3, elongated in the lengthwise direction of the element 1 and, preferably, for reasons of symmetry which are not strictly necessary , parallel to the edges defined by the edge 3 and the faces of the ribs 5 and 6 of the element 1 and of the panel. The tongues 4 are either in one piece with the element 1 proper, being produced during the manufacture of the latter, or, on the contrary, added. Instead of two tabs 4 and 4 ', a greater number of tabs can be provided. The tongues 4 and 4 'are either continuous, that is to say uninterrupted from one end to the other of the element 1, or, on the contrary, discontinuous and therefore comprising interruptions. The latter solution can be adopted in particular in the case of non-contiguous blades 2.

Les languettes 4 et 4' sont destinées à s'engager dans les rainures 7 et 7' lesquelles elles coopèrent pour le soudage et ce, dans chacune des lames 2, transversalement, dans chacune de ses faces d'extrémités tournées vers un chant intérieur 3.The tongues 4 and 4 'are intended to engage in the grooves 7 and 7' which they cooperate for welding and this, in each of the blades 2, transversely, in each of its end faces turned towards an inner edge 3 .

Dans un mode préférentiel de réalisation, les rainures 7 et 7' ne sont pas pratiquées à l'avance dans chaque lame 2 mais réalisées au moment même de l'assemblage du panneau par les languettes 4, pénétrant dans cette lame 2 de manière que l'association rigide et indissociable, montantlame réalisée par thermosoudage soit d'excellente qualité.In a preferred embodiment, the grooves 7 and 7 'are not made in advance in each blade 2 but produced at the same time as the assembly of the panel by the tongues 4, penetrating into this blade 2 so that the 'rigid and inseparable association, jamb blade made by heat sealing is of excellent quality.

Dans une variante d'exécution illustrée par la figure 3, est associée rigidement à l'élément 1 au moins une languette secondaire 8 et préférentiellement deux languettes secondaires 8 saillant du chant intérieur 3 et prolongeant respectivement les faces des côté 5 et 6 du cadre, ce qui assure un recouvrement de la jonction lame 2 - élément 1. Ces languettes secondaires 8 peuvent également permettre le maintien de joints d'étanchéité ou autres. Naturellement, les languettes secondaires 8 peuvent être places aussi en retrait faces du cadre pour constituer des éléments enjoliveurs. La face visible d'une languette 8 peut être quelconque, plane, arrondie, etc., selon les besoins.In an alternative embodiment illustrated by FIG. 3, is rigidly associated with the element 1 at least one secondary tab 8 and preferably two secondary tabs 8 projecting from the inner edge 3 and respectively extending the sides of the sides 5 and 6 of the frame, which ensures overlap of the blade junction 2 - element 1. These secondary tabs 8 can also allow the maintenance of seals or the like. Naturally, the secondary tongues 8 can also be placed recessed on the sides of the frame to form decorative elements. The visible face of a tongue 8 can be any, flat, rounded, etc., as required.

Le procédé d'assemblage suivant l'invention est le suivant : on commence d'abord par disposer les différentes lames 2 constituant un panneau dans les positions relatives définitives qu'elles occuperont par rapport aux éléments 1. On les maintient ensuite en place par tout moyen approprié. On chauffe ensuite, par tout moyen approprié et pendant la durée souhaitable, les languettes 4 et 4' d'un premier élément 1 situé d'un même côté du panneau. Simultanément ou successivement, on chauffe les extrémités coplanaires des lames 2 correspondants, également pendant la durée nécessaire. On procède ensuite au rapprochement de l'élément 1 vers l'extrémité des lames 2 en appuyant de manière que les languettes 4 et 4' pénètrent dans les faces d'extrémités des lames 2 en formant et constituant ainsi les rainures 7 et 7' et ce, jusqu'à ce que le chant intérieur 3 vienne se bloquer contre la face d'extrémité des lames 2. Compte tenu du chauffage effectué précédemment, on réalise outre les rainures 7 et 7', le soudage effectif des lames 2 à l'élément 1. Ensuite on réjète les opérations mentionnées ci-dessus pour les autres extrémités des lames 2 et le second élément 1 opposé au premier et constituant l'autre côté du panneau. Le rapprochement des éléments constituant les deux côtés du panneau se faisant face peut être réalisé simultanément ou bien successivement.The assembly method according to the invention is as follows: first of all, the various blades 2 constituting a panel are placed in the final relative positions which they will occupy relative to the elements 1. They are then held in place by all appropriate means. The tabs 4 and 4 ′ of a first element 1 situated on the same side of the panel are then heated, by any appropriate means and for the desirable duration. Simultaneously or successively, the coplanar ends of the corresponding blades 2 are heated, also for the time necessary. Next, the element 1 is brought towards the end of the blades 2 by pressing so that the tongues 4 and 4 ′ penetrate into the end faces of the blades 2, thus forming and constituting the grooves 7 and 7 ′ and this, until the inner edge 3 comes to lock against the end face of the blades 2. Taking into account the heating carried out previously, one carries out besides the grooves 7 and 7 ', the effective welding of the blades 2 to the element 1. Then one rejects the operations mentioned above for the other ends of the blades 2 and the second element 1 opposite the first and constituting the other side of the panel. The elements constituting the two sides of the panel facing each other can be brought together simultaneously or alternately.

Naturellement, le procédé peut faire l'objet de nombreuses variantes de la sorte. Ainsi, on peut concevoir de souder chaque lame 2 à l'élément 1 séparément. On peut aussi concevoir de souder des lames 2 simultanément aux deux éléments 1 parallèles opposés constituant le cadre, ou bien successivement, etc.Naturally, the process can be the subject of numerous variants of this kind. Thus, it is conceivable to weld each blade 2 to the element 1 separately. It is also conceivable to weld blades 2 simultaneously to the two opposite parallel elements 1 constituting the frame, or alternatively, etc.

En pratique, on a constaté que la durée de chauffage des languettes devait être plus longue que celle des extrémités des lames du fait que la surface à chauffer sur les éléments 1 est plus importante que celle à chauffer sur les lames 2.In practice, it has been found that the heating time of the tongues must be longer than that of the ends of the blades because the surface to be heated on the elements 1 is greater than that to be heated on the blades 2.

La machine pour la mise en oeuvre du procédé comprend, dans une forme plus complexe, deux règles chauffantes 9 destinées à être amenées chacune au contact d'un élément 1 et d'une extrémité de lame.The machine for implementing the method comprises, in a more complex form, two heating rules 9 intended to be brought each into contact with an element 1 and with a blade end.

Entre les règles chauffantes 9, sont placés des supports 10 de maintien et de blocage d'une pluralité de lames 2 dans leur sens longitudinal et dans leur sens transversal perpendiculaire. Deux chariots 11 sont placés de part et d'autre des règles chauffantes 9, comme illustré par la figure 4. Ces chariots 11 qui sont destinés à recevoir les éléments 1, comportent le long de leur bord extérieur chacun un élément longitudinal de blocage 11 a par lequel l'élément 1 peut être bloqué dans son sens longitudinal. Les chariots 11 sont montés mobiles dans le sens transversal de l'élément 1 c'est-à-dire longitudinalement par rapport aux lames 2 (les lames 2 étant orthogonales aux montants 1) grâce à des moyens de coulissement 11 b appropriés. Les règles chauffantes 9 sont portées par des moyens supports 9a qui permettent d'une part de déplacer ces règles 9 de manière que celles-ci puissent être appliquées sur les lames 2 et d'autre part de les escamoter de l'espace compris entre les chariots 11 et les supports 10.Between the heating rules 9, are placed supports 10 for holding and blocking a plurality of blades 2 in their longitudinal direction and in their perpendicular transverse direction. Two carriages 11 are placed on either side of the heating rules 9, as illustrated in FIG. 4. These carriages 11 which are intended to receive the elements 1, have along their outer edge each a longitudinal blocking element 11a by which the element 1 can be blocked in its longitudinal direction. The carriages 11 are mounted movable in the transverse direction of the element 1, that is to say longitudinally with respect to the blades 2 (the blades 2 being orthogonal to the uprights 1) by means of suitable sliding means 11 b. The heating rules 9 are carried by support means 9a which allow on the one hand to move these rules 9 so that they can be applied to the blades 2 and on the other hand to retract them from the space between the carriages 11 and supports 10.

Par coulissement des chariots 11 à à l'aide des moyens 11 b, les éléments 1 bloqués par les éléments de blocage 1 1 peuvent être amenés au contact des règles 9 pour chauffer les languettes 4 et 4' et également appuyés contre les extrémités des lames 2, lorsque les moyens support 9a sont escamotés.By sliding the carriages 11 using the means 11b, the elements 1 blocked by the blocking elements 1 1 can be brought into contact with the rules 9 to heat the tongues 4 and 4 'and also pressed against the ends of the blades 2, when the support means 9a are retracted.

Le fonctionnement de la machine qui vient d'être décrite est le suivant : on place d'abord les lames 2 de manière qu'elles se trouvent dans la position correspondant à leur position définitive dans le panneau à réaliser. On met en oeuvre les supports 10 de manière que ces lames soient ainsi bloquées. On place ensuite deux éléments 1 sur les chariots 11 en les bloquant à l'aide des moyens 11 a. On met en oeuvre les règles chauffantes 9 et dans une première phase, on amène les règles 9 au contact des languettes 4 et 4' afin de les chauffer. Dans une deuxième phase, on amène les règles chauffantes 9 au contact des extrémités des lames 2. Les règles chauffantes 9 sont ensuite escamotées et les chariots 11 déplacés l'un en direction de l'autre de manière que les languettes 4 et 4' associées aux éléments 1 commencent à se rapprocher des lames 2, puis viennent en contact avec les extrémités des lames 2, puis s'enfoncent dans celles-ci ultérieurement en formant les rainures 7 et 7'. On maintient les chariots 11 dans la position finale dans laquelle les chants 3 des éléments 1 sont contre les extrémités des lames 2 et ce jusqu'à thermosoudage.The operation of the machine which has just been described is as follows: the blades 2 are first placed so that they are in the position corresponding to their final position in the panel to be produced. The supports 10 are used so that these blades are thus blocked. Then two elements 1 are placed on the carriages 11 by blocking them using the means 11 a. The heating rules 9 are implemented and in a first phase, the rules 9 are brought into contact with the tongues 4 and 4 ′ in order to heat them. In a second phase, the heating rules 9 are brought into contact with the ends of the blades 2. The heating rules 9 are then retracted and the carriages 11 moved one towards the other so that the tongues 4 and 4 'associated elements 1 begin to approach the blades 2, then come into contact with the ends of the blades 2, then sink into them later by forming the grooves 7 and 7 '. The carriages 11 are kept in the final position in which the edges 3 of the elements 1 are against the ends of the blades 2 and this until heat-sealing.

Il est important de noter que l'invention met à profit les languettes dont disposent les éléments du cadre pour former les rainures dans les lames et permettre ainsi une liaison rigide élément - lame. Cette liaison rigide permet une rigidité importante du fait des nombreux points d'ancrage existant entre les lames et le cadre, ce qui rend le panneau indislocable. De plus, ces résultats peuvent être atteints sans affecter pour autant l'aspect esthétique du panneau puisque la soudure est totaiement invisible.It is important to note that the invention takes advantage of the tongues available to the elements of the frame to form the grooves in the blades and thus allow a rigid element-blade connection. This rigid connection allows significant rigidity due to the numerous anchoring points existing between the blades and the frame, which makes the panel indissociable. In addition, these results can be achieved without affecting the aesthetic appearance of the panel since the weld is completely invisible.
