Abstract

The tile has two plane and rectangular parts (1, 2), where each part has upper faces and lower faces. The two parts are joined along a junction plane (J), and the lower faces are placed opposite to a frame of a fascia-board. The two parts are extended along planes (A, B), which encloses an angle (C) between the parts. The angle opens from the side of the lower faces. An elevated rib (3) is provided at the side of the lower faces, where the length of the rib is lower than the length of the tile.

Description

L'invention concerne une tuile pour un bord de toit.The invention relates to a tile for a roof edge.

Les tuiles destinées à être utilisées pour former un bord de toit, de telles tuiles étant également appelées tuiles de rive, comportent au moins deux parties. Chacune des au moins deux parties présente une face supérieure et une face inférieure, les faces inférieures étant destinées à être mise en regard d'une charpente de toit. Les deux parties ou, lorsque la tuile comporte plus que deux parties, les deux parties principales s'étendent suivant des plans qui enferment entre eux un angle généralement obtus ouvert du côté des faces inférieures de la tuile.Tiles intended to be used to form a roof edge, such tiles also being called roof tiles, comprise at least two parts. Each of the at least two parts has an upper face and a lower face, the lower faces being intended to be placed next to a roof structure. The two parts or, when the tile has more than two parts, the two main parts extend in planes which enclose between them a generally open open angle on the side of the lower faces of the tile.

Lors de la fabrication de tuiles, les tuiles fraîchement formées ou pressées sont entreposées pendant un temps prédéterminé pour les laisser sécher avant de les introduire dans un four de cuisson. Le support peut être essentiellement de deux natures. Selon la première, le support est spécifiquement formé de manière que les tuiles fraîchement pressées ou formées épousent le support au moins sur leur plus grande partie. Selon la seconde nature, le support est une plaque essentiellement plane et les tuiles fraîchement formées y reposent sur deux de leurs bords au moins approximativement parallèles entre eux.In the manufacture of tiles, freshly formed or pressed tiles are stored for a predetermined time to allow them to dry before being introduced into a baking oven. The support can be essentially of two kinds. According to the first, the support is specifically shaped so that the freshly pressed or shaped tiles embrace the support at least for the greater part. According to the second nature, the support is a substantially flat plate and freshly formed tiles rest on two of their edges at least approximately parallel to each other.

L'utilisation de supports spécifiquement formés pour recevoir un modèle de tuile ou éventuellement aussi des variantes de ce type de tuile demande un investissement assez important en moyens de fabrication, ce qui a une influence désavantageuse sur le prix de revient des tuiles. De plus, l'utilisation de supports spécifiquement formés demande de la part des ouvriers préposés au remplissage de ces supports une manipulation comparativement lente, puisque chacune des tuiles fraîchement formées doit être disposée précisément sur l'emplacement prévu pour ne pas annuler l'effet voulu du support spécifique. Enfin, sans être exhaustif dans l'énoncé des désavantages de l'utilisation de supports spécifiquement formés, même une manipulation comparativement lente des tuiles fraîchement formées ne garantit pas que toutes les tuiles soient bien placées sur le support et n'évite donc pas une déformation des tuiles pendant le séchage. Par ailleurs, l'utilisation de supports spécifiquement formés entraîne parfois des contraintes de manipulation lors de l'insertion des supports dans un chariot moyennant lequel les tuiles doivent être disposées ensuite dans un four de cuisson.The use of supports specifically formed to receive a tile model or possibly also variants of this type of tile requires a significant investment in manufacturing means, which has a disadvantageous influence on the cost of tiles. In addition, the use of specifically formed supports requires from the workers responsible for filling these supports a comparatively slow manipulation, since each of the freshly formed tiles must be disposed precisely on the intended location to not cancel the intended effect of the specific media. Finally, without being exhaustive in stating the disadvantages of using specifically formed supports, even comparatively slow handling of freshly formed tiles does not guarantee that all tiles are well placed on the support and thus do not prevent deformation tiles during drying. Moreover, the use of specifically formed supports sometimes leads to handling constraints when inserting the supports in a trolley by means of which the tiles must then be placed in a baking oven.

L'utilisation de supports sensiblement plans ne connaît pas les contraintes énoncées ci avant, mais en connaît d'autres. Ainsi, lorsque des tuiles de rive fraîchement formées doivent être entreposées sur un support plan le temps de leur séchage, il faut que les différentes parties de la tuile aient une certaine épaisseur pour garantir une stabilité de forme suffisante et pour éviter ainsi une déformation par gravité. Généralement, l'épaisseur des différentes parties des tuiles doit être supérieure à 20 mm. L'épaisseur des tuiles ayant un impact sur le poids de chacune des tuiles, cette mesure de stabilisation entraîne donc, outre le grand poids des tuiles et notamment des tuiles dans des conditionnements habituels, une consommation accrue en matériau de tuiles.The use of substantially flat supports does not know the constraints mentioned above, but knows others. Thus, when freshly formed edge tiles are to be stored on a flat support the time of their drying, it is necessary that the different parts of the tile have a certain thickness to ensure a sufficient stability of shape and thus avoid a deformation by gravity . Generally, the thickness of the different parts of the tiles must be greater than 20 mm. The thickness of the tiles having an impact on the weight of each of the tiles, this stabilization measure therefore entails, in addition to the great weight of the tiles and in particular tiles in conventional packaging, increased consumption of tile material.

Le but de l'invention est de remédier aux inconvénients décrits ci avant et de proposer une solution qui permette la réalisation de tuiles de rive sans épaisseur inutile et sans nécessité d'utiliser des supports de séchage spécifiquement formés.The object of the invention is to overcome the disadvantages described above and to provide a solution that allows the realization of bank tiles without unnecessary thickness and without the need to use specifically formed drying media.

Le but de l'invention est atteint avec une tuile pour un bord de toit, la tuile ayant au moins deux parties dont chacune présente une face supérieure et une face inférieure, les faces inférieures étant destinées à être mises en regard d'une charpente du toit, deux des parties s'étendant suivant des plans qui enferment entre eux un angle ouvert du côté des faces inférieures.The object of the invention is achieved with a tile for a roof edge, the tile having at least two parts each having an upper face and a lower face, the lower faces being intended to be placed opposite a frame of the roof, two of parts extending in planes which enclose an open angle between them on the side of the lower faces.

Conformément à l'invention, la tuile est pourvue, du côté des faces inférieures, d'au moins une nervure de soutien destinée à assurer le soutien de la tuile pendant la fabrication de la tuile.According to the invention, the tile is provided, on the side of the lower faces, with at least one support rib intended to ensure the support of the tile during the manufacture of the tile.

Grâce à cette disposition de l'invention, pendant la fabrication de la tuile, chacune des tuiles ainsi formées ne repose pas uniquement sur ses bords ou sur d'autres parties de la tuile prévues à cet effet, mais aussi sur un moyen d'appui ou de soutien supplémentaire disposé entre les bords ou autres endroits prévus à cet effet. Cette nervure de soutien constitue une ligne d'appui intermédiaire s'étendant non nécessairement à distance égale des deux bords ou endroits équivalents.With this arrangement of the invention, during the manufacture of the tile, each of the tiles thus formed does not rest only on its edges or on other parts of the tile provided for this purpose, but also on a support means or additional support arranged between the edges or other places provided for this purpose. This support rib constitutes an intermediate support line extending not necessarily at equal distance from the two edges or equivalent places.

Dans sa forme de réalisation la plus simple, une tuile selon l'invention comporte deux parties planes rectangulaires et jointives dans le sens de la longueur des deux parties. Une des deux parties est destinée à être posée sur la charpente d'un toit alors que l'autre partie est destinée à former le rebord du toit. Les deux parties forment alors un angle ouvert du côté des faces inférieures de la tuile, c'est-à-dire du côté des faces destinées à être mises en regard de la charpente. Conformément à l'invention, la tuile est pourvue, du côté des faces inférieures, d'une nervure de soutien s'étendant sur au moins une partie de la ligne de jonction entre les deux parties de la tuile. Le plan dans lequel cette nervure de soutien s'étend divise alors l'angle ouvert entre les deux parties de la tuile en deux angles partiels non nécessairement égaux. En effet, la nervure de soutien est orientée de manière qu'elle s'étende, lorsque la tuile est posée sur une surface plane, perpendiculairement par rapport à cette surface. En conséquence, l'angle que les deux parties enferment entre elles, généralement un angle obtus, est divisé en fonction de la largeur de chacune des deux parties de la tuile. La hauteur de la nervure est alors déterminée de manière que la tuile, lorsqu'elle est posée sur la surface plane, repose à la fois sur ses deux bords longitudinaux et sur la nervure de soutien.In its simplest embodiment, a tile according to the invention comprises two flat rectangular portions joined in the direction of the length of the two parts. One of the two parts is intended to be placed on the frame of a roof while the other part is intended to form the edge of the roof. The two parts then form an open angle on the side of the lower faces of the tile, that is to say on the side faces intended to be placed next to the frame. According to the invention, the tile is provided on the side of the lower faces, a support rib extending over at least a portion of the junction line between the two parts of the tile. The plane in which this support rib extends then divides the open angle between the two parts of the tile into two partial angles that are not necessarily equal. Indeed, the support rib is oriented so that it extends, when the tile is placed on a flat surface, perpendicularly to this surface. Consequently, the angle that the two parts enclose with each other, generally an obtuse angle, is divided according to the width of each of the two parts of the tile. The height of the rib is then determined so that the tile, when placed on the flat surface, rests both on its two longitudinal edges and on the support rib.

Par ailleurs, la ou chacune des nervures est formée sous celle(s) des parties de la tuile qui est (qui sont) destinée(s) à être fixée(s) sur la charpente.Furthermore, the or each of the ribs is formed in that (s) parts of the tile which is (are) intended (s) to be fixed (s) on the frame.

Lorsque la tuile de rive comporte deux parties symétriques par rapport à la ligne de jonction des deux parties, que les deux bords longitudinaux ou transversaux sur lesquels la tuile repose lorsqu'elle est posée sur une surface plane, soient strictement parallèles entre elles ou non, la nervure de soutien s'étend alors suivant un plan divisant l'angle en deux angles partiels égaux.When the edge tile has two parts symmetrical with respect to the junction line of the two parts, that the two longitudinal or transverse edges on which the tile rests when it is placed on a flat surface, are strictly parallel to each other or not, the support rib then extends along a plane dividing the angle into two equal partial angles.

Pour des réalisations plus complexes de tuiles de rive telle que celle décrite par exemple en référence aux dessins, d'autres configurations peuvent être nécessaires pour obtenir un appui d'une tuile suivant trois lignes d'appui.For more complex embodiments of edge tiles such as that described for example with reference to the drawings, other configurations may be necessary to obtain a support of a tile along three lines of support.

Selon une telle configuration, la nervure de soutien peut être orientée au moins approximativement parallèlement à l'un ou à l'autre des deux bords sur lesquels la tuile doit reposer.According to such a configuration, the support rib may be oriented at least approximately parallel to one or the other of the two edges on which the tile must rest.

Selon encore une autre disposition de l'invention chacune des tuiles peut comprendre au moins une nervure orientée au moins approximativement transversalement à un des deux bords sur lesquels la tuile doit reposer pendant la fabrication. Dans ce cas, la longueur de la nervure transversale peut être inférieure à la largeur de la partie de la tuile sur laquelle elle se dresse.According to yet another embodiment of the invention each of the tiles may comprise at least one rib oriented at least approximately transversely to one of the two edges on which the tile must rest during manufacture. In this case, the length of the transverse rib may be less than the width of the part of the tile on which it stands.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description ci-après d'un mode de réalisation de l'invention. Cette description est faite en référence aux dessins dans lesquels :

  • la figure 7 représente un exemple de disposition de plusieurs tuiles de l'invention.
Other features and advantages of the present invention will emerge from the following description of an embodiment of the invention. This description is made with reference to the drawings in which:
  • the figure 1 schematically represents the position of a tile on a drying rack,
  • the figure 2 represents the tile of the figure 1 in a deformed state at the end of a drying phase,
  • the figure 3 schematically represents a tile according to the invention disposed on a drying support,
  • the figure 4 represents a tile of the invention in a view on the upper faces of the tile,
  • the figure 5 represents the tile of the figure 4 in a view on the lower faces of the tile showing in particular the arrangement of two supporting ribs,
  • the figure 6 represents the tile of the figure 4 in a perspective view angularly slightly offset with respect to the longitudinal extent of the support rib, and
  • the figure 7 represents an example of a layout of several tiles of the invention.

Les figures 1 et 2 représentent schématiquement une tuile pour un bord de toit, disposée sur un support de séchage D constitué par une plaque sensiblement plane.The Figures 1 and 2 schematically represent a tile for a roof edge, arranged on a drying support D consisting of a substantially flat plate.

La tuile comprend deux parties planes et rectangulaires 1, 2 dont chacune présente une face supérieure référencée respectivement 11 et 21 et une face inférieure référencée respectivement 12 et 22. Les deux parties 1, 2 se rejoignent le long d'un plan de jonction J.The tile comprises two planar and rectangular portions 1, 2 each having an upper face respectively referenced 11 and 21 and a lower face respectively referenced 12 and 22. The two parts 1, 2 meet along a junction plane J.

Comme la figure 1 le montre par ailleurs, les deux parties 1, 2 s'étendent suivant les plans A, B qui enferment entre eux un angle C ouvert du côté des faces inférieures 12, 22.As the figure 1 shows, moreover, the two parts 1, 2 extend along the planes A, B which enclose between them an open angle C on the side of the lower faces 12, 22.

Lorsque la tuile est posée sur un support de séchage D et lorsqu'elle n'est pas pourvue de nervure de soutien, ni d'aucun autre moyen de support pour maintenir la forme de la tuile pendant son séchage, les deux parties 1, 2 se déforment souvent, par effet de gravité, comme le montre plus particulièrement la figure 2.When the tile is placed on a drying rack D and when it is not provided with supporting rib, or any other support means to maintain the shape of the tile during drying, the two parts 1, 2 often deform by gravity, as shown more particularly by the figure 2 .

Lorsque, par contre, on applique les dispositions de l'invention comme cela est représenté sur la figure 3, une nervure de soutien 3 est formée du côté des faces inférieures 12, 22 et cette nervure de soutien 3 s'étend au moins sur une partie de la tuile le long du plan de jonction J. En même temps, la hauteur H de la nervure de soutien 3 est déterminée de manière que la tuile, lorsqu'elle est posée sur la surface plane D, repose à la fois sur les bords 13, 23 des deux parties 1, 2 de la tuile et sur un bord libre 33 de la nervure 3.When, on the other hand, the provisions of the invention are applied as shown in figure 3 a support rib 3 is formed on the side of the faces 12, 22 and this support rib 3 extends at least over a portion of the tile along the junction plane J. At the same time, the height H of the support rib 3 is determined so that the tile, when it is placed on the flat surface D, rests on both the edges 13, 23 of the two parts 1, 2 of the tile and on a free edge 33 of the rib 3.

Ainsi, grâce à la présence de la nervure de soutien 3 convenablement dimensionnée, chacune des deux parties 1, 2 de la tuile repose par ses propres bords sensiblement parallèles sur le support D, la partie 1 par les bords 13, 33 et la partie 2 par les bords 23, 33, et les deux parties ne s'appuient plus réciproquement l'une sur l'autre. Cette décharge réciproque des deux parties de la tuile évite que la tuile s'affaisse au cours du séchage, puisque la gravité ne peut plus exercer ses effets, ou au moins pas plus que sur toute tuile plate que l'on met au séchage.Thus, thanks to the presence of the support rib 3 suitably sized, each of the two parts 1, 2 of the tile rests by its own substantially parallel edges on the support D, the part 1 by the edges 13, 33 and the part 2 by the edges 23, 33, and the two parts no longer rest on each other. This reciprocal discharge of the two parts of the tile prevents the tile from sagging during drying, since gravity can no longer exert its effects, or at least not more than on any flat tile that is put to drying.

En ce qui concerne la disposition de la nervure de soutien 3 par rapport aux deux parties 1, 2 de la tuile, celle-ci est essentiellement régie par deux conditions. D'une part, la nervure est formée sous celle des deux parties de la tuile, ici la partie 2, qui est destinée à être fixée sur la charpente.Regarding the arrangement of the support rib 3 with respect to the two parts 1, 2 of the tile, it is essentially governed by two conditions. On the one hand, the rib is formed under that of the two parts of the tile, here the part 2, which is intended to be fixed on the frame.

D'autre part, la nervure 3 s'étend suivant un plan E qui, dans l'exemple dessiné sur la figure 3, divise l'angle C en deux angles partiels approximativement égaux, puisque les deux parties 1, 2 de la tuile ont à peu près la même largeur. Toutefois, comme il est aisé à comprendre d'après les règles de géométrie, la nervure de soutien 3 serait disposée différemment si les deux parties 1, 2 avaient des largeurs différentes, et l'angle C serait alors divisé en deux angles partiels inégaux. L'essentiel est toutefois que la nervure 3 soit orientée de manière que, lorsque la tuile est déposée sur le support D, la nervure 3 s'étende au moins approximativement perpendiculairement par rapport à la surface du support D.On the other hand, the rib 3 extends along a plane E which, in the example drawn on the figure 3 divides the angle C into two approximately equal partial angles, since the two parts 1, 2 of the tile have approximately the same width. However, as it is easy to understand from the geometry rules, the support rib 3 would be arranged differently if the two parts 1, 2 had different widths, and the angle C would then be divided into two unequal partial angles. The essential thing is that the rib 3 is oriented so that, when the tile is deposited on the support D, the rib 3 extends at least approximately perpendicular to the surface of the support D.

Les figures 4 à 6 représentent un exemple de réalisation d'une tuile de rive selon les critères de l'invention.The Figures 4 to 6 represent an embodiment of a roof tile according to the criteria of the invention.

La tuile de l'invention comprend une partie 1 sensiblement rectangulaire de longueur LT et présentant une face supérieure 11 et une face inférieure 12 et une partie 2 approximativement trapézoïdale de longueur MT, inférieure à la longueur LT de la partie 1, et de largeur maximale MU et qui présente une face supérieure 21 et une face inférieure 22. Alors que la partie 1 est conformée pour dépasser d'une charpente dont elle doit couvrir le bord droit ou gauche, la partie 2 est conformée pour être fixée sur la charpente, par exemple par vissage ou cloutage. Les figures 4 à 6 représentent une tuile pour un bord gauche d'une toiture. Une tuile correspondante pour un bord droit d'une toiture sera fabriquée de manière symétrique, comme représentée sur la figure 7.The tile of the invention comprises a substantially rectangular portion 1 of length LT and having an upper face 11 and a lower face 12 and an approximately trapezoidal portion 2 of length MT, less than the length LT of part 1, and of maximum width MU and which has an upper face 21 and a lower face 22. While the portion 1 is shaped to protrude from a frame which it must cover the right or left edge, the portion 2 is shaped to be fixed on the frame, for example by screwing or nailing. The Figures 4 to 6 represent a tile for a left edge of a roof. A corresponding tile for a straight edge of a roof will be made symmetrically, as shown on the figure 7 .

Les parties 1 et 2 s'étendent suivant des plans A, B enfermant entre eux un angle C ouvert du côté des faces inférieures 12, 22. Les parties 1 et 2 sont formées de manière que la partie 1 dépasse la partie 2 sur une seule des deux extrémités opposées de la tuile afin de former une zone de dépassement 14 (figure 5) utile pour le recouvrement des tuiles de rives avec les tuiles de couverture demi-rondes, comme cela est représenté sur la figure 7.Parts 1 and 2 extend along planes A, B enclosing between them an open angle C on the side of lower faces 12, 22. Parts 1 and 2 are formed so that part 1 passes part 2 on a single two opposite ends of the tile to form a passing zone 14 ( figure 5 ) useful for covering the bank tiles with half-round roof tiles, as shown on the figure 7 .

La tuile de l'invention comprend en outre une nervure de soutien longitudinale 3 de longueur LN et une nervure de soutien transversale 4 de longueur MN. Alors que la nervure longitudinale 3 s'étend approximativement le long du plan de jonction J et donc approximativement parallèlement à un bord 13 de la partie 1 de la tuile, la nervure transversale 4 est orientée approximativement transversalement par rapport à la nervure longitudinale 3 et donc disposée approximativement transversalement par rapport au bord 13 de la partie 1 de la tuile.The tile of the invention further comprises a longitudinal support rib 3 of length LN and a transverse support rib 4 of length MN. While the longitudinal rib 3 extends approximately along the junction plane J and therefore approximately parallel to an edge 13 of the part 1 of the tile, the transverse rib 4 is oriented approximately transversely with respect to the longitudinal rib 3 and therefore arranged approximately transversely to the edge 13 of the part 1 of the tile.

Par ailleurs, la nervure longitudinale 3 s'étend entre deux points NA, NB espacés des extrémités opposées de la tuile, dont il résulte que la longueur LN de la nervure longitudinale 3 est inférieure à la longueur LT de la partie 1 et donc de la tuile et aussi inférieure à la longueur de la partie 2 de la tuile.Furthermore, the longitudinal rib 3 extends between two points NA, NB spaced from the opposite ends of the tile, which results that the length LN of the longitudinal rib 3 is less than the length LT of the part 1 and therefore the tile and also less than the length of part 2 of the tile.

Pour assurer l'effet de soutien de la tuile pendant sa fabrication, qui est au coeur de l'existence de la nervure longitudinale 3 et aussi de celle de la nervure transversale 4, la nervure longitudinale 3 a une hauteur H (indiquée sur la figure 3) suffisamment grande pour que, lorsque la tuile est posée sur une surface sensiblement plane D, la tuile repose à la fois sur les bords 13 et 23 des deux parties 1 et 2 de la tuile et sur la nervure 3.To ensure the support effect of the tile during its manufacture, which is at the heart of the existence of the longitudinal rib 3 and also that of the transverse rib 4, the longitudinal rib 3 has a height H (indicated on the figure 3 ) large enough so that, when the tile is placed on a substantially flat surface D, the tile rests on both the edges 13 and 23 of the two parts 1 and 2 of the tile and on the rib 3.

De manière analogue, la hauteur de la nervure transversale 4 mesurée du côté de la nervure longitudinale 3, est déterminée de manière que, lorsque la tuile est posée sur une surface sensiblement plane D, la tuile repose à la fois sur les bords 13 et 23, sur la nervure 3 et sur la nervure 4.Similarly, the height of the transverse rib 4 measured on the side of the longitudinal rib 3, is determined so that, when the tile is placed on a substantially flat surface D, the tile rests on both the edges 13 and 23 , on the rib 3 and on the rib 4.

La figure 6 représente le mode de réalisation d'une tuile de l'invention décrite en référence aux figures 4 et 5 en une vue en perspective légèrement déviée du plan dans lequel s'étend la nervure longitudinale 3. Cette figure montre que la tuile, lorsqu'elle est posée sur une surface sensiblement plane D, repose à la fois sur les bords 13 et 23 des parties 1 et 2 de la tuile ainsi que sur la nervure longitudinale 3 et la nervure transversale 4.The figure 6 represents the embodiment of a tile of the invention described with reference to figures 4 and 5 in a perspective view slightly deviated from the plane in which the longitudinal rib 3 extends. This figure shows that the tile, when it is placed on a substantially flat surface D, rests on both the edges 13 and 23 of the parts 1 and 2 of the tile as well as on the longitudinal rib 3 and the transverse rib 4.

La figure 7 représente un ensemble de trois tuiles de rive selon l'invention pour un bord de toit gauche, deux tuiles de rive selon l'invention pour un bord de toit droite et six tuiles de couverture posées sur un support pour démontrer que la tuile de l'invention peut être réalisée aussi bien pour une rive droite qu'une rive gauche et qu'elle peut être assemblée avec des tuiles de couverture T de type tuile romane comportant une partie demi-cylindrique marquée par des extrémités arquées T1, T2.The figure 7 represents a set of three edge tiles according to the invention for a left roof edge, two edge tiles according to the invention for a straight roof edge and six roof tiles placed on a support to demonstrate that the tile of the roof invention can be made for a right bank as well as a left bank and that it can be assembled with roofing tiles T of the Roman roof type having a semi-cylindrical part marked by arcuate ends T1, T2.

Comme il est déjà décrit plus haut, les tuiles de rive de l'invention comportent une partie 1 destinée à dépasser de la charpente CH et une partie 2 destinée à être fixée sur la charpente. Ainsi, les trois tuiles de rive gauche comportent chacune une partie 1 dépassant de la charpente CH en oblique vers le bas à gauche de la charpente, tout comme les deux tuiles de rive droite comportent chacune une partie 1 dépassant de la charpente CH en oblique vers le bas à droite de la charpente.As already described above, the edge tiles of the invention comprise a part 1 intended to protrude from the frame CH and a part 2 intended to be fixed on the frame. Thus, the three left bank tiles each have a portion 1 protruding from the frame CH obliquely down to the left of the frame, just as the two right bank tiles each comprise a portion 1 protruding from the frame CH obliquely to the bottom right of the frame.

Les tuiles de rive, droite et gauche, comprennent un zone de dépassement 14 par laquelle elles ne recouvrent que la zone correspondante de la partie 1 de la tuile suivante, mais ne recouvrent pas la zone adjacente de la partie 2 de la tuile suivante.The edge tiles, right and left, include an overflow area 14 by which they cover only the corresponding area of part 1 of the next tile, but do not cover the adjacent area of part 2 of the next tile.
