These heating elements 3 are assembled between them by two rigid collectors 4 arranged transversely to the elements, which are fixed to collectors 4 by welding so that the whole constitutes a front or rear panel of the radiator.
- Each collector 4 is preferably produced under the shape of a hollow tube with square or rectangular section and each heating element 3 is preferably made in the form of a hollow parallelepiped of relatively thin, but it is understood that each manifold and each heating element may have different sections and shapes.
- the two heating bodies 1, 2 are rigidly joined together by means of their respective collectors 4, each collector 4 of the heating body 1 being secured to the manifold 4 which facing him from the other heater 2 by by means of two fixing parts 5, one of which embodiment is shown in detail in the figures 3 to 6.

- Figure 4 shows the axial forces of opposite directions C exerted by the bottoms of the recesses 13 on the pins 9a, 10a to press the wall parts 4a of adjacent collectors 4 respectively against two opposite sides of the collar 7.
- the pins 9a, 10a are immobilized and the forces of opposite directions resulting from the local elastic deformation of the material constituting the funds of these recesses are sufficient to ensure final locking of the lugs in these recesses without being able to remove them from these if one wishes to ensure total inviolability of the assembly between them of the collectors 4 with respect to users of the heating radiator.
- the rigidity of the fixing of the two radiator heating bodies by the parts 5 allows it to withstand the stresses of various natures such as for example static weight of the radiator, the dynamic forces appearing during transport, assembly, handling, etc. from radiator, the expansion efforts resulting from the circulation of hot water throughout the radiator.
- the assembly by parts 5 of the manifolds of heating body provides excellent mechanical resistance
- the method of assembling two radiator heaters by fasteners according to the invention allows paint the heaters and their collectors and fasteners before assembly and, if applicable if necessary, to assemble two colored heaters different or different finishes.
- each fastener 5 can nevertheless be unlocked only by manufacturing personnel radiators or qualified after-sales service without that the characteristics described be modified previously from the assembly.
- the number of fasteners 5 necessary to rigidly fix the heating bodies 1, 2 of the radiator is a function of the dimensions of the heater to assemble.
- the assembly of the manifolds 4 of the two heating bodies allows a gain in heating power of the radiator as well achieved by approximately 22% compared to the solution conventional consisting in fixing by welding such collectors.
- Each part 5 as described with reference to the figures 1 to 6 is drilled axially so as to ensure the circulation of water between the two heating elements 1, 2 of the radiator. However, it is possible to prohibit a water circulation between two adjacent collectors assembled together by making part 5 so that one of the male parts 6, 8 or both male parts are full. It is also possible to provide a fastener 5 of adjacent collectors fixed axially hollow assembly and the other fastener 5 of these two axially full manifolds to achieve specific water circulation between the two bodies 1, 2.
- each piece 5 is as a sealing element for an opening corresponding 11 of a collector 4.
- the part 5 is as shown in FIG. 3 with at at least one of the male parts 6, 8 full while being fixed in the opening 11 sealingly by the pins 10a forcibly engaged respectively in the two recesses 13 of collector 4.
- part 5 is also possible to make part 5 as shown in Figure 7 which shows that this part has only one male part 6 (or 8) with pins 9a (or 10a) for fixing the part in the orifice 11 of a manifold 4, the face plane of the collar 7 opposite the male part closing off this last and can be used as a wall hanging piece a radiator heating controller.
- a O-ring will be interposed between the collar 7 and the wall 4a of the corresponding collector 4.

Description
La présente invention concerne une pièce destinée en particulier à fixer rigidement deux corps de chauffe d'un radiateur de chauffage.The present invention relates to a part intended for particular to rigidly fix two heating bodies of a heating radiator.
On connaít un radiateur de chauffage du type comprenant deux corps de chauffe constitués respectivement de deux panneaux d'éléments chauffants séparés pouvant être disposés verticalement ou horizontalement, les éléments chauffants d'un panneau étant fixés par soudage à deux collecteurs généralement sous forme de tube creux à section transversale carrée s'étendant transversalement aux éléments chauffants. Les deux corps de chauffe sont fixés l'un à l'autre par l'intermédiaire de leurs collecteurs respectifs soudés ensemble.We know a heating radiator of the type comprising two heating bodies consisting respectively of two separate heating element panels which can be arranged vertically or horizontally, the elements heaters of a panel being fixed by two welding collectors generally in the form of hollow tubes square cross section extending transversely to the heating elements. The two heaters are attached to each other through their respective collectors welded together.
Ce mode d'assemblage par soudure des corps de chauffe d'un radiateur de chauffage, outre son coût élevé, nécessite de peindre le radiateur une fois que les deux corps de chauffe sont assemblés, de sorte que certains emplacements d'accès difficile des soudures ne sont pas correctement recouverts du revêtement de peinture avec pour inconvénient que des traces de rouille peuvent apparaítre à la longue. De plus, l'assemblage par soudures de ces corps de chauffe n'est pas esthétique..This method of assembling the heating bodies by welding a heating radiator, in addition to its high cost, requires painting the radiator once both heaters are assembled, so that some difficult access locations of welds are not properly covered with paint coating with drawback that traces of rust can appear in the long run. In addition, the assembly by welding of these heating elements is not aesthetic.
EP-A-0 186 614 décrit un ensemble de connecteurs permettant la fixation ou la séparation rapide de conduits de fluide qui font partie par exemple des lignes d'alimentation en gaz pour des moyens de chauffage à gaz.EP-A-0 186 614 describes a set of connectors allowing fast attachment or separation of fluid conduits which are part for example of lines gas supply for gas heating means.
Cependant, ce document antérieur ne s'adresse pas du tout au problème d'assemblage rigidement l'un à l'autre de deux éléments rigides au moins en partie creux, tels que deux collecteurs d'un radiateur du chauffage.However, this earlier document is not intended at all to the problem of rigidly joining one to the other of two rigid elements at least partially hollow, such as two manifolds of a heating radiator.

De préférence, chaque évidement est réalisé entre deux bossages de la face interne de la paroi plane de l'élément creux correspondant de manière qu'en appliquant le couple au collet, chaque ergot passe en force sur l'un des bossages pour retomber dans l'évidement correspondant et être immobilisé dans celui-ci entre les deux bossages.Preferably, each recess is made between two bosses on the inside of the flat wall of the corresponding hollow member so that by applying the torque at the collar, each lug goes in force over one bosses to fall back into the corresponding recess and be immobilized therein between the two bosses.

De préférence, chaque collecteur est en forme de tube creux à section carrée.Preferably, each collector is in the form of a tube hollow square section.
L'invention vise enfin un procédé de réalisation d'un radiateur de chauffage comprenant deux corps de chauffe pouvant être traversés par un fluide caloporteur et quatre collecteurs en forme de tubes creux à section carrée, dont deux sont solidaires d'un corps de chauffe et les deux autres solidaires de l'autre corps de chauffe, les collecteurs étant deux à deux assemblés ensemble afin que les deux corps de chauffe soient fixés parallèlement l'un à l'autre et et qui est caractérisé en ce qu'il consiste à poser sensiblement horizontalement sur une surface du support l'un des deux corps de chauffe de façon que les deux collecteurs de celui-ci aient leurs parois planes, opposées à celles solidaires du corps de chauffe, dirigées vers le haut ; à engager dans chacune de deux ouvertures opposées de chaque collecteur, réalisées à travers la paroi plane dirigée vers le haut de celui-ci, une partie mâle d'une pièce telle que définie précédemment, avec le collet de la pièce en appui sur une partie de cette paroi plane et l'autre partie mâle de la pièce faisant saillie du collecteur sensiblement perpendiculairement à la paroi plane ; à poser l'autre corps de chauffe sur le premier corps de chauffe de façon que chacune des autres parties mâles en saillie des pièces s'engage dans chacune des deux ouvertures opposées correspondantes de chaque collecteur de l'autre corps de chauffe réalisées à travers les parois planes de ces deux collecteurs faisant face respectivement aux parois planes des deux collecteurs du corps de chauffe en appui sur la surface de support et venant en appui par gravité sur chaque collet d'une pièce, et à appliquer sur chaque collet un couple provoquant l'engagement à force de deux paires d'ergots d'une pièce respectivement dans deux paires d'évidements diamétralement opposés réalisés respectivement dans les deux faces internes correspondantes de deux parois planes se faisant face de deux collecteurs, de manière à plaquer à force les parties de parois planes se faisant face des collecteurs respectivement sur les deux faces opposées du collet et fixer ainsi rigidement deux à deux les collecteurs des deux corps de chauffe.The invention finally relates to a method for producing a heating radiator comprising two heating bodies can be crossed by a heat transfer fluid and four collectors in the shape of hollow section tubes square, two of which are integral with a heating body and the other two in solidarity with the other body of heats, the collectors being two to two assembled together so that the two heaters are attached parallel to each other and which is characterized by what it consists of laying substantially horizontally on one surface of the support one of the two heating bodies so that the two collectors of it have their flat walls, opposite to those integral with the body of heaters, directed upwards; to engage in each two opposite openings of each collector, made through the flat wall facing upwards of it, a male part of a piece such as defined above, with the collar of the part in support on one part of this flat wall and the other part male part protruding from manifold substantially perpendicular to the flat wall; at place the other heating body on the first body of heats up so that each of the other male parts protrusion of the parts engages in each of the two corresponding opposite openings of each manifold of the other heating body made through the flat walls of these two manifolds facing respectively to the flat walls of the two collectors of the heating element resting on the support surface and coming to bear by gravity on each collar of a piece, and apply a couple on each collar causing the forceful engagement of two pairs of lugs of a part respectively in two pairs of recesses diametrically opposed respectively made in two corresponding internal faces of two flat walls facing two collectors, so as to tackle by force the parts of flat walls facing each other collectors respectively on the two opposite sides of the collar and thus rigidly fix two by two the collectors of the two heating bodies.

cylindrique 8 solidaire du collet 7 coaxialement à celui-ci
et faisant saillie du collet perpendiculairement à
celui-ci à l'opposé de la partie mâle 6. Les deux parties
mâles 6, 8 ont un diamètre identique et une longueur
identique à partir du collet 7 de façon à être
symétriques par rapport à ce collet. La partie mâle 6
comporte un axe cylindrique rigide 9 traversant
diamétrialement la partie mâle 6 en faisant saillie
extérieurement de celle-ci de manière à définir deux
ergots externes 9a diamétralement opposés. De même, la
partie mâle 8 comporte un axe cylindrique 10 traversant
diamétralement la partie 8 en faisant saillie à
l'extérieur de celle-ci de manière à définir deux ergots
externes 10a diamétralement opposés. Les deux axes 9, 10
sont situés dans le même plan médian longitudinal de la
pièce 5, c'est-à-dire des parties mâles 6, 8 et du collet
7, et sont symétriques par rapport à ce collet. Ce
dernier comporte deux méplats opposés 7a dont la fonction
sera expliquée ultérieurement.Each
Chaque collecteur 4 comporte sur sa paroi plane 4a,
opposée à celle fixée aux éléments chauffants 3, deux
orifices ou ouvertures 11 réalisées à travers la paroi
plane 4a et situées au voisinage respectivement des deux
extrémités du collecteur 4. Chaque ouverture 11 de forme
générale circulaire comporte deux entailles
diamétralement opposées 12 de forme rectangulaire
réalisées à travers la paroi 4a du collecteur 4. Les deux
entailles 12 permettent l'introduction respectivement de
deux ergots 9a ou 10a d'une partie mâle 6 ou 8 comme on
le verra ultérieurement.Each collector 4 has on its
Deux évidements diamétralement opposés 13, disposés
sensiblement à 90° de chaque entaille 12, sont formés
dans la face interne de la paroi 4a d'un collecteur 4 et
conformés pour recevoir respectivement deux ergots 9a de
la partie mâle 6 ou 10a de la partie mâle 8. Chaque
évidement 13 est défini entre deux bossages 14 en
retrait, intérieurement au collecteur, de la face interne
de la paroi 4a de manière à faire pénétrer à force chaque
ergot 9a ou 10a dans son évidement correspondant 13 dont
le fond est également en retrait intérieurement de la
face interne de la paroi 4a du collecteur correspondant
4. De préférence, chaque évidement 13 présente en section
transversale une forme en V s'étendant à partir du bord
de l'ouverture 11 dans la face interne de la paroi 4a sur
une distance au moins égale à la longueur de chaque ergot
9a, 10a.Two diametrically
Un joint torique 15 peut être prévu entre chacune des
deux faces opposées du collet 7 et la partie
correspondante de paroi 4a d'un collecteur 4 afin
d'assurer l'étanchéité au fluide caloporteur pouvant
traverser chaque collecteur 4 en provenance d'un orifice
d'entrée 4b de ce collecter auquel peut être raccordé une
conduite d'arrivée de fluide caloporteur (non
représentée). Les deux joints toriques 15 peuvent
également assurer l'étanchéité au fluide lorsque ce
dernier traverse le perçage axial formé par les deux
parties mâles creuses 6, 8 de la pièce 5 de fixation de
deux collecteurs adjacents 4 du radiateur. Chaque joint
15 est logé dans une gorge annulaire 16 réalisée dans la
face de paroi correspondante du collet 7. An O-
Le principe d'assemblage et de fixation des deux corps de
chauffe 1, 2 pour former un radiateur ressort déjà de la
description qui précède et va être maintenant décrit.The principle of assembly and fixing of the two bodies of
Tout d'abord, l'un 1 des corps de chauffe est disposé
horizontalement sur une surface de support appropriée de
façon que les deux collecteurs 4 de celui-ci aient leurs
parois 4a dirigées vers le haut comme représenté aux
figures 1 et 6. Ensuite, une pièce 5 de la figure 3 est
engagée dans chacune des ouvertures 11 de manière que la
partie mâle inférieure, par exemple 8, et les ergots
correspondant 10a s'engagent respectivement dans
l'ouverture 11 et les entailles 12 avec ces ergots se
trouvant en aplomb des entailles respectives 12 en étant
situés à un niveau légèrement en dessous de la face
interne de la paroi correspondante 4a. Bien entendu, le
joint torique 15, logé intialement dans sa gorge
annulaire correspondante 16, se trouve alors interposé
entre le collet 7 et la partie circulaire correspondante
de la paroi 4a. Ainsi, chaque pièce 5 repose, par
l'intermédiaire de son collet 7, sur la paroi 4a du
collecteur correspondant 4 avec l'autre partie mâle, dans
le cas présent 6, faisant saillie de la paroi 4a
perpendiculairement à celle-ci. L'autre joint torique 15
est logé dans l'autre gorge annulaire 16 du collet 7 de
chaque pièce 5 et l'autre corps de chauffe 2 est disposé
au dessus du corps de chauffe 1 auquel il doit être fixé
par les pièces 5 de façon que les deux collecteurs 4 du
corps de chauffe 2 soient en aplomb ou au dessus
respectivement des deux collecteurs 4 de l'autre corps de
chauffe 1 avec leurs parois respectives 4a se faisant
face. En descendant verticalement chaque collecteur 4 du
corps de chauffe 2 comme indiqué par la flèche A en
figure 6, chaque partie mâle saillante 6 d'une pièce 5 et
ses ergots 9a s'engagent alors respectivement dans
l'ouverture 11 et les entailles 12 correspondantes du
collecteur 4 de façon que les ergots 9a soient situés à
un niveau légèrement en retrait de la face interne de la
paroi 4a du collecteur 4 du corps de chauffe 2. Une fois
que les deux collecteurs 4 du corps de chauffe 2 sont en
appui par gravité par leurs parois correspondantes 4a sur
les quatre collets 7 des pièces 5, un opérateur engage
une clé plate de manoeuvre de part et d'autre des méplats
7a de chaque pièce 5 au travers de l'espace défini entre
deux collecteurs contigus 4. L'opérateur fait alors
tourner chaque pièce 5 à l'aide de sa clé de manoeuvre
dans un sens déterminé, par exemple celui des aiguilles
d'une montre comme indiqué par la flèche B en figure 6,
de manière à amener en même temps les ergots 9a, 10a en
appui contre chaque bossage correspondant 14 se trouvant
en premier sur leur trajectoire. L'opérateur exerce alors
sur le collet 7, par la clé de manoeuvre, un couple
important de manière à faire passer en force sur chaque
bossage 14, par déformation élastique de la partie de
paroi 4a comportant chaque paire de bossages 14 et
l'évidement correspondant 13 entre ces deux bossages,
chaque ergot 9a, 10a qui tombe ensuite dans son évidement
correspondant 13. Puisque chaque évidement 13 est en
retrait de la face interne de la paroi 4a du collecteur
correspondant 4, les fonds respectifs de ces évidements
13 exercent sur les ergots 9a, 10a de chaque pièce des
forces élastiques résultant de la déformation élastique
de la matière constituant chaque évidement entre deux
bossages et tendant à plaquer énergiquement les portions
correspondantes de paroi 4a des collecteurs 4 contre les
faces opposées des collets 7 avec écrasement concomitant
des joints toriques 15 entre collets 7 et parois 4a des
collecteurs 4. La figure 4 montre les forces axiales de
sens opposés C exercées par les fonds des évidements 13
sur les ergots 9a, 10a pour plaquer les parties de paroi
4a de collecteurs adjacents 4 contre respectivement les
deux faces opposées du collet 7.First, one 1 of the heaters is arranged
horizontally on a suitable support surface of
so that the two collectors 4 of it have their
Une fois en place au fond des évidements 13, les ergots
9a, 10a sont immobilisés et les forces de sens opposés
résultant de la déformation élastique locale de la
matière constituant les fonds de ces évidements sont
suffisantes pour assurer un blocage définitif des ergots
dans ces évidements sans que l'on puisse les retirer de
ceux-ci si l'on souhaite assurer l'inviolabilité totale
de l'assemblage entre eux des collecteurs 4 vis à vis des
utilisateurs du radiateur de chauffage. La rigidité de la
fixation des deux corps de chauffe du radiateur par les
pièces 5 lui permet de résister aux sollicitations de
diverses natures telles que par exemple le poids statique
du radiateur, les efforts dynamiques apparaissant lors du
transport, du montage, de la manutention, etc du
radiateur, les efforts de dilatation résultant de la
circulation d'eau chaude dans l'ensemble du radiateur. Du
fait que l'assemblage par les pièces 5 des collecteurs de
corps de chauffe assure une excellente tenue mécanique,
il est possible d'utiliser les joints toriques 15 de
façon à assurer une étanchéité parfaite à la pression
d'eau circulant dans les corps de chauffe. De plus, le
mode d'assemblage de deux corps de chauffe d'un radiateur
par des pièces de fixation conformes à l'invention permet
de peindre les corps de chauffe et leurs collecteurs et
les pièces de fixation avant leur assemblage et, le cas
échéant, d'assembler deux corps de chauffe de couleurs
différentes ou de finitions différentes.Once in place at the bottom of the
Si l'inviolabilité de la fixation des collecteurs 4 doit
être assurée vis à vis des utilisateurs du radiateur,
chaque pièce de fixation 5 peut néanmoins être
déverrouillée uniquement par le personnel de fabrication
des radiateurs ou le service après vente qualifié sans
que soient modifiées les caractéristiques décrites
précédemment de l'assemblage.If the inviolability of the attachment of the collectors 4 must
be insured vis-à-vis the users of the radiator,
each
Bien entendu, le nombre de pièces de fixation 5
nécessaires pour fixer rigidement les corps de chauffe 1,
2 du radiateur est fonction des dimensions des corps de
chauffe à assembler.Of course, the number of
L'assemblage des collecteurs 4 des deux corps de chauffe permet un gain de puissance de chauffe du radiateur ainsi réalisé d'environ 22 % par rapport à la solution classique consistant à fixer par soudage de tels collecteurs.The assembly of the manifolds 4 of the two heating bodies allows a gain in heating power of the radiator as well achieved by approximately 22% compared to the solution conventional consisting in fixing by welding such collectors.
Chaque pièce 5 telle que décrite en référence aux figures
1 à 6 est percée axialement de manière à assurer la
circulation de l'eau entre les deux corps de chauffe 1, 2
du radiateur. Cependant, il est possible d'interdire une
circulation d'eau entre deux collecteurs adjacents
assemblés ensemble en réalisant la pièce 5 de façon que
l'une des parties mâles 6, 8 ou les deux parties mâles
soient pleines. Il est également possible de prévoir une
pièce de fixation 5 de collecteurs adjacents fixés
ensemble axialement creuse et l'autre pièce de fixation 5
de ces deux collecteurs axialement pleine pour réaliser
des circulations d'eau spécifiques entre les deux corps
de chauffe 1, 2.Each
Il est également possible, dans le cas d'un radiateur à
un seul corps de chauffe 1 ou 2, d'utiliser chaque pièce
5 comme élément de fermeture étanche d'une ouverture
correspondante 11 d'un collecteur 4. A cet effet, la
pièce 5 est telle que représentée en figure 3 avec au
moins une des parties mâles 6, 8 pleine en étant fixée
dans l'ouverture 11 de façon étanche par les ergots 10a
engagés à force respectivement dans les deux évidements
13 du collecteur 4. Pour ce même effet, il est également
possible de réaliser la pièce 5 comme représentée en
figure 7 qui montre que cette pièce comporte une seule
partie mâle 6 (ou 8) à ergots 9a (ou 10a) de fixation de
la pièce dans l'orifice 11 d'un collecteur 4, la face
plane du collet 7 opposée à la partie mâle obturant cette
dernière et pouvant servir de pièce d'accrochage mural
d'un ccrps de chauffe du radiateur. Bien entendu, un
joint torique sera interposé entre le collet 7 et la
paroi 4a du collecteur correspondant 4.It is also possible, in the case of a radiator with
a
On notera enfin que dans le cadre de la fixation de deux
collecteurs de deux corps de chauffe d'un radiateur à
l'aide des pièces de fixation 5, il est possible
d'utiliser des collecteurs de grandes dimensions ou de
grandes surfaces, contrairement à la solution connue
jusqu'à maintenant selon laquelle les collecteurs sont
fixés ensemble par soudage déformant des parois planes de
grandes dimensions de ces collecteurs.Finally, it should be noted that in the context of fixing two
manifolds of two heating bodies from a radiator to
using
Si l'invention a été décrite en application à la fixation de deux corps de chauffe d'un radiateur tels que représentés aux figures 1 et 2, elle peut également s'appliquer à la fixation de collecteurs de corps de chauffe de radiateurs de structures différentes ou, d'une manière générale, à la fixation d'éléments d'appareils ou de dispositifs autres que des radiateurs de chauffage.If the invention has been described in application to the fixation two radiator heaters such as shown in Figures 1 and 2, it can also apply to the fixing of body collectors heating radiators of different structures or, of a generally, to the fixing of elements of apparatus or of devices other than heating radiators.
