Definitions
- the invention relates to a panel articulation system according to the preamble of the first claim and its application to sectional doors.
- Sectional doors (garage doors, factory doors, warehouses and other similar closures) are composed of a plurality of horizontally extending panels, which are hinged together to be able to slide vertically and fold at the top of the opening to extend horizontally in the upper part of the room.
- the present invention proposes to provide a new articulation system of the type comprising, on the one hand, a hinge in the form of a flexible profile disposed between panels over the width thereof, on the other hand, edge profiles of panels shaped to keep said flexible hinge.
- An objective of the invention is to provide a system which combines excellent sealing qualities with great robustness allowing in particular to apply it to sectional doors.
- Another objective is to guarantee a precise positioning of the panels with respect to each other, positioning of precision comparable to that provided by rigid hinges.
- Another objective is to considerably reduce the risks for users, in particular the risk of pinching fingers between panels.
- the flexible hinge can be made of an elastomeric material, its central flange being able to be solid or hollow; closure plugs can in the latter case be arranged at its two ends in order to trap air in said tube and to combine a pneumatic effect with the elasticity of the material.
- the articulation system according to the invention which extends over the entire width of the panels, forms a very effective tight barrier which prevents any infiltration.
- Such a system is very robust because the deformation of the flexible hinge is effected at the level of a flange which essentially undergoes compression or tensile stresses (and not bending stresses as is the case in known flexible hinges ).
- these constraints are limited by the rotating guide surfaces, which reduce the amplitude of the deformations of the flexible hinge.
- the above-mentioned structure of said hinge and the presence of these guide surfaces guarantee precise positioning of the panels over the entire angular range of pivoting.
- the system according to the invention benefits from rapid assembly carried out by simple snap-fastening.
- the edge profiles advantageously comprise tensile retaining surfaces, arranged so that the retaining surfaces of one edge profile come opposite the retaining surfaces of the other profile. edge in order to withstand the spacing forces between panels. In this way, the tensile stresses exerted on the flexible hinge are also limited, whatever the loads applied to the system.
- one of the edge profiles comprises two profiles snap-fit one on the other: on the one hand, a main profile forming an incomplete housing for the latching head of the flexible hinge, on the other hand, a clip capable of snapping onto this main profit and comprising a heel for locking the aforementioned housing.
- Such an embodiment facilitates assembly of the system, while leading to profiles of simplified structures, which are easy to extrude.
- the above-mentioned clip is adapted to snap onto the main profit by three clipping zones: a central zone located on the side of the aforementioned housing, an intermediate zone and an extreme zone situated at the end of a wing that has the clip opposite its locking heel. This gives a good connection of this clip on the main profile.
- the articulation system according to the invention can be applied to articulate two by two the sectional door panels in order to obtain watertight, robust, well balanced doors, benefiting from reliable operation.
- the articulation system presented in the disassembled state in FIG. 1 essentially consists of a first edge profile consisting of two profiles which can be snapped onto each other (a main profile 1 and a clip 2), a second edge profile 3 and a flexible hinge profile 4.
- Profiles 1 and 2 and profile 3 are in particular made of extruded light alloy (aluminum), while the flexible profile 4 is made of elastomer. Thereafter, we will speak indifferently of "profiled” or “profit” to designate these elements.
- profiles 1 and 3 comprise in the first place structures, such as 5 or 6, adapted for the clipping of a joinery in particular of bay window; in addition, each of these sections is provided, on the one hand, with a groove 7 or 8 for inserting the edge of a sheet metal called to form the front face of the panel, on the other hand, with a wing 16 or 17 for holding the edge of a sheet metal called to form the rear face of the panel; in the example, the groove 7 of the profile 1 extends in a horizontal plane, the sheet coming into it after folding at 90 °, and the groove 8 of the profile 2 extends in a vertical plane, the sheet coming insert it after folding 180 ° (the terms “horizontal” and “vertical” refer to a position of the panels in a vertical plane, their border extending horizontally).
- Profile 1 and 3 comprise in the first place structures, such as 5 or 6, adapted for the clipping of a joinery in particular of bay window; in addition, each of these sections is provided, on the one hand, with a groove 7 or 8
- At least one of the profiles 1 or 3 (in the example the profile 1) is provided, in its axial plane X, with a circular bore 9 for the laterally positioning of axes of rollers.
- at least one of the edge profiles (in the example the profile 1) comprises, on one side, latching structures 10 of an inertia reinforcement (shown diagrammatically at R in FIG. 1) .
- sections 1, 2 and sections 3 form housings L1 and L2 opening on edge in the vicinity of the median planes X and X ′ with a view to snap-fitting the flexible hinge profit 4.
- housings have a generally triangular section as shown in Figure 1.
- the housing L2 is entirely delimited by the profile 3, while the profile 1 defines an incomplete housing 11a devoid of one of the lateral returns; this housing is completed to make the housing L1 by a locking heel 11b carried by the clip 2.
- the surfaces S x , S v have centered circular sections, when the system is mounted, near the center C of the flexible hinge, so as to guide the pivoting of the panels around an axis of rotation passing substantially through this center. It is the same for the circular wing A L and the conjugate surfaces S ax and S ac which are centered near the center of the hinge.
- the convex surface S x of the profile 1 is interrupted by a groove 12 adapted to form a water receiver prohibiting upwelling of water along it by capillary action.
- the sections 1 and 3 comprise bearing surfaces, formed by flats M1 and M2 substantially orthogonal to the median planes, which allow the sections to rest l one against the other in alignment position of the panels.
- These flats located in the immediate vicinity of the median planes ensure in this alignment position a balanced transmission of the compression loads between panels, avoiding excessive crushing of the flexible hinge. They are supplemented by positioning flats M3 and M4 parallel to the median planes which are applied against each other when the panels arrive in the alignment position, thus precisely defining this position.
- the first retaining surfaces B1, B2 are constituted by oblique flats (in particular at 45 ° with respect to the median planes) which cooperate when the profiles arrive in the alignment position and a spacing force is exerted on these. This arrangement prevents the flexible hinge from undergoing excessive tensile forces, while guaranteeing freedom of rotation of the joint even under high tensile force.
- the wing A L of the clip 2 is provided so that its internal face f i comes opposite the surface S ax from the alignment position, so that the first and second retaining surfaces have a common angular working range; this avoids that, for certain angles, the tensile forces are not taken up and are exerted on the flexible hinge.
- the clip 2 has a convex shape which is intended to form an additional fulcrum by pressing against the external wall of the bore 9 of profile 1.
- the flexible hinge 4 is constituted by a hollow central tube 13 and by two wings 14 and 15 which are attached to opposite portions of this tube and provided with latching heads 14a and 15a.
- the central flange pushes the profiles 1, 2 and 3 in opposite directions by coming to bear against bearing surfaces such as A1 and A2 that these profiles have in the vicinity of the housings L1 and L2 , on each side of the opening of these.
- the elasticity effect of the tube 13 (due to its shape and to the nature of the material which constitutes it) can, if necessary, be reinforced by a pneumatic effect by sealingly sealing the tube at each of its ends.
- the wings 14 and 15 of the flexible hinge 4 are attached to the flange, so as to form between them, at rest, an angle between 140 ° and 160 °, in particular of the order of 150 ° as shown in Figure 1
- the flexible hinge is thus able to undergo, from this rest position, opposite deformations when the panels pivot to their alignment position or to their extreme angular position; thus reducing the amplitude of the deformations it undergoes, it causes the hinge to work in better conditions and it increases its service life.
- the snap heads 14a and 15a are generally approximately triangular in shape, adapted to enter their housing by the play of their elasticity and to be housed therein without risk of tearing when the system is mounted.
- each head has, at its base; two shoulders which are retained by the front returns of the housing L1 or L2 as well as biased front faces which allow the passage of the head in the opening of the housing during assembly.
- Figures 2, 3 and 4 show the system according to the invention respectively in the position corresponding to the alignment of the panels (Figure 2), in an intermediate pivoting position corresponding to the rest state of the flexible hinge 4 ( figure 3) and in the extreme pivoting position (figure 4).
- the profiles 1, 2 and 3 are in a generally rectangular shape, the central flange 13 of the flexible hinge being located in the center of said rectangle when the assembly is mounted (latching heads 14a and 15a in place in their housing L1 or L2; housing L1 closed by the locking heel 11b of the clip).
- the flats M1 and M2 of profiles 1 and 2 are supported and support most of the load.
- the panels are precisely positioned with respect to one another by the set of conjugate surfaces capable of coming to bear (guide surfaces S c and S x , guide and retaining surfaces f i and S ax ; retaining surfaces B1 and B2).
- FIGS 5 to 10 show the system mounting process.
- the flexible hinge 4 is first snapped onto the profile 3 by the play of the elasticity of its snap-on head 15a and the panels are presented opposite one another in an angular position as illustrated in Figure 5.
- the latching head 14a is inserted into the incomplete housing L1 of the profile 1 (FIG. 6).
- the clip is then snapped onto profile 1 by inserting its snap structures 2a and 2b onto the conjugate structures 1a and 1b of profile 1 ( Figure 9).
- FIG 11 shows, in partial section, a sectional door equipped with articulation systems according to the invention.
- the panels are articulated two by two by means of these systems, with the lateral edge of the insertion of axes of rollers in the bores 9; the position of these rollers (in the median plane of each panel) considerably improve the kinematics of the sectional door (compared to known doors whose rollers are necessarily offset relative to the median plane of the panels).
- each panel is constituted by a rear plate 18 bearing against the retaining wings 16 and 17 of the profiles of two neighboring systems, by a layer 19 of a filling material such as polyurethane foam and by a front plate 20 whose edges are folded at 90 ° or 180 ° to fit into the grooves 7 and 8 of the profiles of the two neighboring systems.
- a stiffener R can be snapped into the structure 10 provided for this purpose. This stiffener forms a gutter which is expanded from place to place by "pop" r ′ rivets in order to form a block with the profile.
- FIG. 12 shows the box of a panel fitted with a window carpentry 21; the latter is fixed in a manner known per se to the profiles of the articulation systems by virtue of the structures 5 and 6 provided for this purpose.

Abstract
Description
L'invention concerne un système d'articulation de panneaux suivant le préambule de la première revendication et son application aux portes sectionnelles.The invention relates to a panel articulation system according to the preamble of the first claim and its application to sectional doors.
Les portes sectionnelles (portes de garage, d'usines, d'entrepots et autres fermetures analogues) sont composé es d'une pluralité de panneaux s'étendant horizontalement, qui sont articulés entre eux pour pouvoir coulisser verticalement et se plier au sommet de l'ouverture afin de s'étendre ensuite horizontalement en partie haute du local.Sectional doors (garage doors, factory doors, warehouses and other similar closures) are composed of a plurality of horizontally extending panels, which are hinged together to be able to slide vertically and fold at the top of the opening to extend horizontally in the upper part of the room.
Les systèmes classiques d'articulation de ces portes sectionnelles sont constitués par des charnières rigides fixées de place en place en façade entre les paires de panneaux. Toutefois, ces systèmes présentent de graves inconvénients : défaut d'étanchéité au niveau des joints entre panneaux, montage long et inesthétique des charnières, risque pour les utilisateurs (en particulier danger de pincement des doigts entre panneaux lorsque ceux-ci se referment).The traditional systems of articulation of these sectional doors are constituted by rigid hinges fixed from place to place in front between the pairs of panels. However, these systems have serious drawbacks: lack of tightness at the joints between panels, long and unsightly mounting of the hinges, risk for users (in particular danger of pinching fingers between panels when they close).
Par ailleurs, il existe des systèmes à charnière flexible, dans lesquels une lame en matériau souple est fixée le long des arêtes de bordure de deux panneaux de sorte que ceux-ci se trouvent reliés par une épaisseur souple qui fait office d'articulation par le jeu de sa déformation, par exemple brevet FR 2 421 332, brevet US 3 527 283 correspondant au préambule de la 1ère revendication. De tels systèmes conduisent à une étanchéité améliorée mais présentent toutefois les graves défauts d'être fragiles, de courte durée de vie et de réaliser un positionnement très imprécis des panneaux ; en particulier, lorsque l'articulation joue, tous les efforts sont concentrés au niveau d'une épaisseur souple relativement mince pour permettre un bon accostage des panneaux ; cette épaisseur se déforme de façon parfois dissymétrique en cas de charges mal équilibrées et subit un vieillissement prématuré. Ces défauts interdisent en pratique d'utiliser de tels systèmes à charnière flexible pour des portes sectionnelles qui, en raison de leurs dimensions, peuvent subir des charges élevées. En outre, ces systèmes ne suppriment pas le danger de pincement des doigts entre panneaux.Furthermore, there are flexible hinge systems, in which a blade of flexible material is fixed along the edge edges of two panels so that these are connected by a flexible thickness which acts as an articulation by the set its deformation, for example patent FR 2,421,332, U.S. patent 3,527,283 corresponding to the preamble of the 1 st claim. Such systems lead to improved sealing but nevertheless have the serious defects of being fragile, of short life and of achieving very imprecise positioning of the panels; in particular, when the joint plays, all the efforts are concentrated at the level of a relatively thin flexible thickness to allow good docking of the panels; this thickness sometimes deforms asymmetrically in the event of poorly balanced loads and undergoes premature aging. These faults prohibit in practice the use of such flexible hinge systems for sectional doors which, because of their dimensions, can be subjected to high loads. In addition, these systems do not eliminate the danger of pinching fingers between panels.
La présente invention se propose de fournir un nouveau système d'articulation du type comprenant, d'une part, une charnière se présentant sous la forme d'un profil flexible disposé entre panneaux sur la largeur de ceux-ci, d'autre part, des profilés de bordure de panneaux conformés pour maintenir ladite charnière flexible.The present invention proposes to provide a new articulation system of the type comprising, on the one hand, a hinge in the form of a flexible profile disposed between panels over the width thereof, on the other hand, edge profiles of panels shaped to keep said flexible hinge.
Un objectif de l'invention est de fournir un système qui associe d'excellentes qualités d'étanchéité à une grande robustesse permettant en particulier de l'appliquer aux portes sectionnelles.An objective of the invention is to provide a system which combines excellent sealing qualities with great robustness allowing in particular to apply it to sectional doors.
Un autre objectif est de garantir un positionnement précis des panneaux les uns par rapport aux autres, positionnement de précision comparable à celui que fournissent les charnières rigides.Another objective is to guarantee a precise positioning of the panels with respect to each other, positioning of precision comparable to that provided by rigid hinges.
Un autre objectif est de réduire considérablement les risques pour les utilisateurs, en particulier risque de pincement des doigts entre panneaux.Another objective is to considerably reduce the risks for users, in particular the risk of pinching fingers between panels.
A cet effet, le système d'articulation conforme à l'invention se caractérisé en ce que :
- (a) la charnière flexible comprend un boudin central agencé au voisinage du plan médian des panneaux et deux ailes rattachées à des portions opposées dudit boudin central et pourvues de têtes d'encliquetage,
- (b) les profilés de bordure de panneaux comprennent :
- . des logements s'ouvrant sur chant au voisinage du plan médian des panneaux et présentant des formes adaptées pour retenir les têtes d'encliquetage des ailes de charnière,
- . des surfaces de guidage en rotatation, agencées de part et d'autre du plan médian des panneaux de sorte que les surfaces de guidage d'un profilé de bordure viennent en regard des surfaces de guidage de l'autre profilé de bordure en vue de guider le pivotement des panneaux autour d'un axe de rotation passant par le boudin central de la charnière flexible ou à proximité de celui-ci.
- (a) the flexible hinge comprises a central rod arranged in the vicinity of the median plane of the panels and two wings attached to opposite portions of said central rod and provided with latching heads,
- (b) panel edge profiles include:
- . housings opening on edge in the vicinity of the median plane of the panels and having shapes suitable for retaining the latching heads of the hinge wings,
- . guide surfaces in rotation, arranged on either side of the median plane of the panels so that the guide surfaces of one edge profile come opposite the guide surfaces of the other edge profile in order to guide the pivoting of the panels around an axis of rotation passing through or near the central flange of the flexible hinge.
La charnière flexible peut être réalisée en un matériau élastomère, son boudin central pouvant être plein ou creux ; des bouchons d'obturation peuvent dans ce dernier cas être disposées à ses deux extrémités en vue d'emprisonner de l'air dans ledit boudin et de combiner un effet pneumatique à l'élasticité du matériau.The flexible hinge can be made of an elastomeric material, its central flange being able to be solid or hollow; closure plugs can in the latter case be arranged at its two ends in order to trap air in said tube and to combine a pneumatic effect with the elasticity of the material.
Le système d'articulation conforme à l'invention qui s'étend sur toute la largeur des panneaux, forme une barrière étanche très efficace qui s'oppose à toute infiltration. Un tel système est très robuste car la déformation de la charnière flexible s'effectue au niveau d'un boudin qui subit essentiellement des contraintes de compression ou de traction (et non des contraintes de flexion comme c'est le cas dans les charnières souples connues). De plus, ces contraintes sont limitées par les surfaces de guidage en rotation, lesquelles réduisent l'amplitude des déformations de la charnière flexible. En outre, la structure sus-évoquée de ladite charnière et la présence de ces surfaces de guidage garantissent un positionnement précis des panneaux sur toute la plage angulaire de pivotement. Comme on le comprendra mieux plus loin, le système conforme à l'invention bénéficie d'un montage rapide s'effectuant par simple encliquetage.The articulation system according to the invention, which extends over the entire width of the panels, forms a very effective tight barrier which prevents any infiltration. Such a system is very robust because the deformation of the flexible hinge is effected at the level of a flange which essentially undergoes compression or tensile stresses (and not bending stresses as is the case in known flexible hinges ). In addition, these constraints are limited by the rotating guide surfaces, which reduce the amplitude of the deformations of the flexible hinge. In addition, the above-mentioned structure of said hinge and the presence of these guide surfaces guarantee precise positioning of the panels over the entire angular range of pivoting. As will be better understood below, the system according to the invention benefits from rapid assembly carried out by simple snap-fastening.
Il est à noter que le pivotement d'un panneau par rapport à un autre s'effectue autour d'un point voisin du plan médian des panneaux ; dans de nombreuses applications, et notamment dans l'application aux portes sectionnelles, cette disposition simplifie la conception des moyens de guidage et d'entraînement des panneaux et permet un meilleur équilibrage des masses en mouvement.It should be noted that the pivoting of one panel with respect to another takes place around a point close to the median plane of the panels; in many applications, and in particular in the application to sectional doors, this arrangement simplifies the design of the means for guiding and driving the panels and allows better balancing of the moving masses.
Selon un mode de réalisation préféré de l'invention, les profilés de bordure comprennent avantageusement des surfaces de retenue en traction, agencées de sorte que les surfaces de retenue d'un profilé de bordure viennent en regard des surfaces de retenue de l'autre profilé de bordure en vue de supporter les efforts d'écartement entre panneaux. De la sorte, on limite également les contraintes de traction qui s'exercent sur la charnière souple quelles que soient les charges appliquées sur le système.According to a preferred embodiment of the invention, the edge profiles advantageously comprise tensile retaining surfaces, arranged so that the retaining surfaces of one edge profile come opposite the retaining surfaces of the other profile. edge in order to withstand the spacing forces between panels. In this way, the tensile stresses exerted on the flexible hinge are also limited, whatever the loads applied to the system.
Par ailleurs, selon un autre mode de réalisation préféré, l'un des profilés de bordure comprend deux profils encliquetables l'un sur l'autre : d'une part, un profil principal formant un logement incomplet pour la tête d'encliquetage de la charnière souple, d'autre part, un clip apte à s'encliqueter sur ce profit principal et comportant un talon de verrouillage du logement précité.Furthermore, according to another preferred embodiment, one of the edge profiles comprises two profiles snap-fit one on the other: on the one hand, a main profile forming an incomplete housing for the latching head of the flexible hinge, on the other hand, a clip capable of snapping onto this main profit and comprising a heel for locking the aforementioned housing.
Une telle forme de réalisation facilite le montage du système, tout en conduisant à des profilés de structures simplifiées, faciles à extruder.Such an embodiment facilitates assembly of the system, while leading to profiles of simplified structures, which are easy to extrude.
En particulier, le clip sus-évoqué est adapté pour s'encliqueter sur le profit principal par trois zones de clipage : une zone centrale située sur le côté du logement précité, une zone intermédiaire et une zone extrême située à l'extrémité d'une ailette que comporte le clip à l'opposé de son talon de verrouillage. On obtient ainsi une bonne solidarisation de ce clip sur le profil principal.In particular, the above-mentioned clip is adapted to snap onto the main profit by three clipping zones: a central zone located on the side of the aforementioned housing, an intermediate zone and an extreme zone situated at the end of a wing that has the clip opposite its locking heel. This gives a good connection of this clip on the main profile.
Le système d'articulation conforme à l'invention peut être appliqué pour articuler deux à deux les panneaux de portes sectionnelles afin d'obtenir des portes étanches, robustes, bien équilibrées, bénéficiant d'un fonctionnement fiable.The articulation system according to the invention can be applied to articulate two by two the sectional door panels in order to obtain watertight, robust, well balanced doors, benefiting from reliable operation.
D'autres buts et avantages de l'invention ressortiront de la description qui suit en référence aux dessins annexés, lesquels en présentent à titre d'exemple non limitatif un mode de réalisation ; sur ces dessins qui font partie intégrante de la présente description :

- FIGS. 2, 3 and 4 are cross sections showing this system mounted in three positions corresponding respectively to the position of alignment of the panels, to an intermediate pivoting position and to the maximum pivoting position,

- Figure 12 shows schematically the case of a panel equipped with a bay joinery.
Le système d'articulation présenté à l'état démonté à la figure 1 se compose essentiellement d'un premier profilé de bordure constitué de deux profils encliquetables l'un sur l'autre (un profil principal 1 et un clip 2), d'un second profilé de bordure 3 et d'un profil flexible de charnière 4.The articulation system presented in the disassembled state in FIG. 1 essentially consists of a first edge profile consisting of two profiles which can be snapped onto each other (a main profile 1 and a clip 2), a
Les profils 1 et 2 et profilé 3 sont en particulier réalisés en alliage léger extrudé (aluminium), cependant que le profil flexible 4 est réalisé en élastomère. Par la suite, on parlera indifféremment de "profilé" ou "profit" pour désigner ces éléments.
Ces profilés sont appelés à s'étendre sur toute la largeur des deux panneaux symbolisés en P₁ et P₂ à la figure 1, le profilé 1 étant solidaire de la bordure de l'un des panneaux et le profilé 3 solidaire de la bordure de l'autre panneau. Pour assurer cette fixation, les profilés 1 et 3 comportent en premier lieu des structures, telles que 5 ou 6, adaptées pour le clipage d'une menuiserie notamment de baie vitrée ; en outre, chacun de ces profilés est doté, d'une part, d'une rainure 7 ou 8 d'insertion du bord d'une tôle appelée à former la façade frontale du panneau, d'autre part, d'une aile 16 ou 17 de maintien du bord d'une tôle appelée à former la façade arrière du panneau ; en l'exemple, la rainure 7 du profilé 1 s'étend selon un plan horizontal, la tôle venant s'y insérer après pliage à 90°, et la rainure 8 du profilé 2 s'étend selon un plan vertical , la tôle venant s'y insérer après repliage à 180° (les termes "horizontal" et "vertical" se réfèrent à une position des panneaux dans un plan vertical, leur bordure s'étendant horizontalement). Les profilés 1 et 3 sont ainsi d'utilisation universelle et susceptibles d'être assujettis en bordure de panneaux de types différents.These profiles are called to extend over the entire width of the two panels symbolized in P₁ and P₂ in Figure 1, the profile 1 being secured to the edge of one of the panels and the
De plus, dans l'application visée (système pour portes sectionnelles), l'un au moins des profilés 1 ou 3 (en l'exemple le profilé 1) est pourvu, dans son plan axial X, d'un alésage circulaire 9 en vue de la mise en place latéralement d'axes de galets de roulement. En outre, l'un au moins des profilés de bordure (en l'exemple le profilé 1) comprend, d'un côté, des structures d'encliquetage 10 d'un renfort d'inertie (schématisé en R à la figure 1).In addition, in the targeted application (system for sectional doors), at least one of the profiles 1 or 3 (in the example the profile 1) is provided, in its axial plane X, with a
Par ailleurs, les profilés 1, 2 et profilés 3 forment des logements L₁ et L₂ s'ouvrant sur chant au voisinage des plans médians X et X′ en vue de l'encliquetage du profit flexible de charnière 4.Furthermore, the
Ces logements ont une section de forme générale triangulaire comme le montre la figure 1.These housings have a generally triangular section as shown in Figure 1.
Le logement L₂ est entièrement délimité par le profilé 3, tandis que le profilé 1 délimite un logement incomplet 11a dépourvu d'un des retours latéraux ; ce logement est complété pour réaliser le logement L₁ par un talon de verrouillage 11b que porte le clip 2.The housing L₂ is entirely delimited by the
Les profilés 1 et 3 comprennent en outre des surfaces de guidage en rotation cosntitués :
- d'un côté des plans médians X, X′, par une surface convexe Sx située sur le profilé 1 et par une surface concave conjuguée Sv située sur le
profilé 3, ces surfaces Sx et Sv venant en regard lorsque le système est monté, - de l'autre côté des plans médians, par une aile circulaire AL équipant le
clip 2 et par deux surfaces circulaires conjugées, concave Sac et convexe Sax, agencées sur leprofilé 3, de façon que l'aile AL s'engage et pénètre entre celles-ci lorsque le système est monté et est amené à pivoter.
- on one side of the median planes X, X ′, by a convex surface S x located on the profile 1 and by a conjugate concave surface S v located on the
profile 3, these surfaces S x and S v coming opposite when the system has climbed, - on the other side of the median planes, by a circular wing A L equipping the
clip 2 and by two conjugate circular surfaces, concave S ac and convex S ax , arranged on theprofile 3, so that the wing A L s' engages and enters between them when the system is mounted and is made to pivot.
Les surfaces Sx, Sv présentent des sections circulaires centrées, lorsque le système est monté, à proximité du centre C de la charnière flexible, de façon à guider le pivotement des panneaux autour d'un axe de rotation passant sensiblement par ce centre. Il en est de même de l'aile circulaire AL et des surfaces conjuguées Sax et Sac qui sont centrées à proximité du centre de la charnière.The surfaces S x , S v have centered circular sections, when the system is mounted, near the center C of the flexible hinge, so as to guide the pivoting of the panels around an axis of rotation passing substantially through this center. It is the same for the circular wing A L and the conjugate surfaces S ax and S ac which are centered near the center of the hinge.
La surface convexe Sx du profilé 1 est interrompue par une rainure 12 adaptée pour former un récepteur d'eau interdisant les remontées d'eau le long de celle-ci par capillarité.The convex surface S x of the profile 1 is interrupted by a
Aux extrémités proches des plans médians X, X′ des surfaces Sx et Sc, les profilés 1 et 3 comprennent des surfaces d'appui, constituées par des méplats M₁ et M₂ sensiblement orthogonaux aux plans médians, qui permettent aux profilés de reposer l'un contre l'autre en position d'alignement des panneaux. Ces méplats situés au voisinage immédiat des plans médians assurent dans cette position d'alignement une transmission équilibrée des charges de compression entre panneaux, évitant un écrasement excessif de la charnière flexible. Ils sont complétés par des méplats de positionnement M₃ et M₄ parallèles aux plans médians qui viennent s'appliquer l'un contre l'autre lorsque les panneaux arrivent dans la position d'alignement, définissant ainsi de façon précise cette position.At the ends close to the median planes X, X ′ of the surfaces S x and S c , the
Les profilés 1, 2, 3 comprennent également des surfaces de retenue en traction qui sont agencées pour supporter les efforts d'écartement entre panneaux. Ces surfaces de retenue sont de deux types :
- . de premières surfaces B₁, B₂ agencées sur les profilés 1
et 3 de façon à venir en regard et supporter les efforts d'écartement lorsque les panneaux se trouvent sensiblement dans l'alignement, - . et de secondes surfaces qui, en l'exemple, coïncident avec la surface de guidage Sax et la face interne fi de l'aile de guidage AL, agencées pour venir en regard et supporter les efforts d'écartement des panneaux lorsque ceux-ci forment un angle.
- . first surfaces B₁, B₂ arranged on the
sections 1 and 3 so as to come opposite and withstand the spacing forces when the panels are substantially in alignment, - . and second surfaces which, in the example, coincide with the guide surface S ax and the internal face f i of the guide wing A L , arranged to come opposite and withstand the spacing forces of the panels when those -these form an angle.
Les premières surfaces de retenue B₁, B₂ sont constituées par des méplats obliques (en particulier à 45° par rapport aux plans médians) qui viennent coopérer lorsque les profilés arrivent en position d'alignement et qu'un effort d'écartement s'exerce sur ceux-ci. Cette disposition évite que la charnière flexible subisse des efforts de traction excessifs, tout en garantissant une liberté de rotation de l'articulation même sous effort de traction élevé.The first retaining surfaces B₁, B₂ are constituted by oblique flats (in particular at 45 ° with respect to the median planes) which cooperate when the profiles arrive in the alignment position and a spacing force is exerted on these. This arrangement prevents the flexible hinge from undergoing excessive tensile forces, while guaranteeing freedom of rotation of the joint even under high tensile force.
Il est à noter que l'aile AL du clip 2 est prévu de sorte que sa face interne fi vienne en regard de la surface Sax à partir de la position d'alignement, de sorte que les première et seconde surfaces de retenue présentent une plage angulaire commune de travail ; on évite ainsi que, pour certains angles, les efforts de traction ne soient pas repris et s'exercent sur la charnière souple.It should be noted that the wing A L of the
Le clip 2 qui porte le talon 11b de verrouillage du logement L₁ a pour fonction essentielle de permettre un montage facile du système. Il est adapté pour s'encliqueter sur le profit principal 1 par trois zones de clipage :
- . une zone dite centrale située sur le côté du logement L₁ au voisinage du plan médian X, le clip étant doté dans cette zone
d'une structure d'encliquetage 2a appelée à coopérer avec une structure conjuguée la que comporte le profilé 1, - . une zone intermédiaire située à la base de l'aile circulaire AL, le clip étant doté dans cette zone
d'une structure d'encliquetage 2b appelée à coopérer avec une ailette conjuguée 1b que comporte le profilé 1, - . une zone extrême située à l'extrémité d'une ailette Ae que comporte le clip à l'opposé de
son talon 11b, cette ailette portant unestructure d'encliquetage 2c appelée à coopérer avec unestructure conjuguée 1c que comporte le profilé 1.
- . a so-called central zone situated on the side of the housing L₁ in the vicinity of the median plane X, the clip being provided in this zone with a snap-in
structure 2a called to cooperate with a conjugate structure la that comprises the profile 1, - . an intermediate zone situated at the base of the circular wing A L , the clip being provided in this zone with a latching
structure 2b called to cooperate with aconjugate fin 1b which comprises the profile 1, - . an end zone situated at the end of a fin A e that the clip comprises opposite its
heel 11b, this fin carrying a latchingstructure 2c called to cooperate with aconjugate structure 1c that comprises the section 1.
Ces dispositions garantissent une solidarisation sûre du clip 2 sur le profit 1, tout en autorisant une grande facilité de mise en place ou de retrait par un opérateur. Il est à noter que, entre le talon 11b et la zone d'encliquetage 2b, le clip 2 présente une forme convexe qui est prévu pour former un point d'appui supplémentaire en venant s'appliquer contre la paroi externe de l'alésage 9 du profil 1.These provisions guarantee a secure attachment of the
Par ailleurs, la charnière flexible 4 est constituée par un boudin central creux 13 et par deux ailes 14 et 15 qui sont rattachées à des portions opposées de ce boudin et pourvues de têtes d'encliquetage 14a et 15a.Furthermore, the
Lorsque le système est en position normale montée, le boudin central repousse les profilés 1, 2 et 3 dans des directions opposées en venant en appui contre des surfaces d'appui telles que A₁ et A₂ que comportent ces profilés au voisinage des logements L₁ et L₂, de chaque côté de l'ouverture de ces derniers. L'effet d'élasticité du boudin 13 (dû à sa forme et à la nature du matériau qui le constitute) peut, le cas échéant, être renforcé par un effet pneumatique en obturant de façon étanche le boudin à chacune de ses extrémités.When the system is in the normal mounted position, the central flange pushes the
Les ailes 14 et 15 de la charnière flexible 4 sont rattachées au boudin, de façon à former entre elles, au repos, un angle compris entre 140° et 160°, en particulier de l'ordre de 150° comme le montre la figure 1. La charnière flexible est ainsi apte à subir, à partir de cette position de repos, des déformations opposées lorsque les panneaux pivotent vers leur position d'alignement ou vers leur position angulaire extrême ; en réduisant ainsi l'amplitude des déformations qu'elle subit, on amène la charnière à travailler dans de meilleures conditions et on accroît sa durée de vie.The
Les têtes d'encliquetage 14a et 15a sont de forme générale approximativement triangulaire, adaptées pour pénétrer dans leur logement par le jeu de leur élasticité et pour s'y loger sans risque d'arrachement lorsque le système est monté.The snap heads 14a and 15a are generally approximately triangular in shape, adapted to enter their housing by the play of their elasticity and to be housed therein without risk of tearing when the system is mounted.
A cet effet, chaque tête comporte, à sa base; deux épaulements qui sont retenus par les retours avant du logement L₁ ou L₂ ainsi que des faces frontales biaises qui permettent le passage de la tête dans l'ouverture du logement lors du montage.For this purpose, each head has, at its base; two shoulders which are retained by the front returns of the housing L₁ or L₂ as well as biased front faces which allow the passage of the head in the opening of the housing during assembly.
Les figures 2, 3 et 4 présentent le système conforme à l'invention respectivement dans la position correspondant à l'alignement des panneaux (figure 2), dans une position intermédiaire de pivotement correspondant à l'état de repos de la charnière flexible 4 (figure 3) et dans la position de pivotement extrême (figure 4).Figures 2, 3 and 4 show the system according to the invention respectively in the position corresponding to the alignment of the panels (Figure 2), in an intermediate pivoting position corresponding to the rest state of the flexible hinge 4 ( figure 3) and in the extreme pivoting position (figure 4).
Dans la position d'alignement des panneaux, les profilés 1, 2 et 3 s'inscrivent dans une forme générale rectangulaire, le boudin central 13 de la charnière flexible étant situé au centre dudit rectangle lorsque l'ensemble est monté (têtes d'encliquetage 14a et 15a en place dans leur logement L₁ ou L₂ ; logement L₁ fermé par le talon de verrouillage 11b du clip). Lorsque les panneaux sont en compression l'un contre l'autre, les méplats M₁ et M₂ des profilés 1 et 2 sont en appui et supportent l'essentiel de la charge. Les panneaux sont positionnés de façon précise l'un par rapport à l'autre par l'ensemble de surfaces conjuguées susceptibles de venir en appui (surfaces de guidage Sc et Sx, surfaces de guidage et du retenue fi et Sax ; surfaces de retenue B₁ et B₂).In the alignment position of the panels, the
Lorsque les panneaux pivotent l'un par rapport à l'autre (figure 3), l'aile AL du clip vient en regard de la surface de guidage Sac qui assure un guidage complémentaire.When the panels pivot relative to each other (FIG. 3), the wing A L of the clip comes opposite the guide surface S ac which provides complementary guidance.
En fin de pivotement (figure 4), la partie extrême du retour qui porte la surface Sac, vient en appui contre l'aile AL du clip formant une butée de fin de course. La charnière 4 s'est déformée en sens inverse par rapport à la position d'alignement.At the end of pivoting (Figure 4), the extreme part of the return which carries the surface S ac , comes to bear against the wing A L of the clip forming an end of stroke stop. The
Un tel système associe de grandes qualités de robustesse à une parfaite étanchéité quelle que soit la position, cependant que les panneaux sont toujours guidés de façon précise l'un par rapport à l'autre. De plus, en position de pivotement, la surface convexe Sx ferme l'angle d'ouverture et réduit considérablement les risques pour les utilisateurs (risques de pincement des doigts ou d'un corps étranger).Such a system combines great qualities of robustness with perfect sealing whatever the position, while the panels are always guided precisely relative to each other. In addition, in the pivoting position, the convex surface S x closes the opening angle and considerably reduces the risks for users (risk of pinching fingers or a foreign body).
Les figures 5 à 10 présentent le processus de montage du système.Figures 5 to 10 show the system mounting process.
La charnière flexible 4 est d'abord encliquetée sur le profilé 3 par le jeu de l'élasticité de sa tête d'encliquetage 15a et les panneaux sont présentés l'un en face de l'autre dans une position angulaire telle qu'illustrée à la figure 5.The
La tête d'encliquetage 14a est insérée dans le logement incomplet L₁ du profilé 1 (figure 6).The latching
Les panneaux sont alors redressés pour les disposer en position d'alignement en vue de l'encliquetage du clip 2. Ce dernier est présenté comme le montre la figure 7, à l'arrière des profilés 1 et 3. Il est introduit dans l'espace libre avec sa structure d'encliquetage 2c en prise avec la structure conjuguée 1c du profilé 1 (figure 8).The panels are then straightened to arrange them in alignment position for the snap-on of
Le clip est ensuite encliqueté sur le profil 1 par insertion de ses structures d'encliquetage 2a et 2b sur les structures conjuguées 1a et 1b du profilé 1 (figure 9).The clip is then snapped onto profile 1 by inserting its
Le système monté est alors prêt à fonctionner (figure 10). On conçoit la grande simplicité du montage du système qui supprime toute opération de perçage et de vissage.The mounted system is then ready to operate (Figure 10). We understand the great simplicity of mounting the system which eliminates all drilling and screwing operations.
La figure 11 présente, en coupe partielle, une porte sectionnelle équipée de systèmes d'articulation conformes à l'invention. Les panneaux sont articulés deux à deux au moyen de ces systèmes, avec en bordure latérale l'insertion d'axes de galets de roulement dans les alésages 9 ; la position de ces galets (dans le plan médian de chaque panneau) améliorent considérablement la cinématique de la porte sectionnelle (par comparaison aux portes connues dont les galets sont nécessairement déportés par rapport au plan médian des panneaux).Figure 11 shows, in partial section, a sectional door equipped with articulation systems according to the invention. The panels are articulated two by two by means of these systems, with the lateral edge of the insertion of axes of rollers in the
En l'exemple de la figure 11, chaque panneau est constitué par une tôle arrière 18 en appui contre les ailes de maintien 16 et 17 des profilés de deux systèmes voisins, par une couche 19 d'un matériau de remplissage tel que mousse de polyuréthane et par une tôle frontale 20 dont les bords sont repliés à 90° ou à 180° pour s'insérer dans les rainures 7 et 8 des profilés des deux systèmes voisins. Un raidisseur R peut être encliqueté dans la structure 10 prévue à cet effet. Ce raidisseur forme une gouttière qui est dilatée de place en place par des rivets "pop" r′ afin de faire bloc avec le profilé.In the example of FIG. 11, each panel is constituted by a
La figure 12 présente le case d'un panneau équipé d'une menuiserie de baie 21 ; celle-ci est fixée de façon connue en soi sur les profilés des systèmes d'articulation grâce aux structures 5 et 6 prévues à cet effet.FIG. 12 shows the box of a panel fitted with a
