Description

"Dispositif d'obturation à verrouillage sélectif". "Selective Locking Shutter Device".
La présente invention concerne, de façon générale, un dispositif permettant d'obturer un cadre et comprenant un couvercle susceptible d'être verrouillé sur le cadre au moyen d'une clé et d'un verrou solidaire du couvercle. Plus précisément, l'invention concerne un dispositif d'obturation à verrouillage sélectif pour obturer un cadre, comprenant un couvercle sensiblement plan sélectivement appliqué sur le cadre, un verrou solidaire du couvercle, et une clé comportant une douille et un bras dont une extrémité porte la douille, le couvercle présentant une ouverture d'accès au verrou pour la clé, le verrou comprenant un pêne coopérant avec une gâche du cadre, et la clé adoptant sélectivement, par rapport à l'ouverture, une position de verrouillage que cette clé peut adopter et quitter librement, et dans laquelle le pêne est retenu prisonnier de la gâche, et une position de déverrouillage pour laquelle la clé est retenue prisonnière "dans l'ouverture et pour laquelle le pêne est dégagé de la gâche.The present invention relates, in general, to a device making it possible to close off a frame and comprising a cover capable of being locked on the frame by means of a key and a bolt secured to the cover. More specifically, the invention relates to a shutter device with selective locking for shuttering a frame, comprising a substantially planar cover selectively applied to the frame, a lock integral with the cover, and a key comprising a socket and an arm, one end of which bears the socket, the cover having an access opening to the lock for the key, the lock comprising a bolt cooperating with a keeper of the frame, and the key selectively adopting, with respect to the opening, a locking position that this key can adopt and leave freely, and in which the bolt is retained prisoner of the striker, and an unlocking position for which the key is retained prisoner " in the opening and for which the bolt is released from the striker.
Un dispositif de ce type est connu dans l'art antérieur et décrit dans la document de brevet EP 0 383 374.A device of this type is known in the prior art and described in patent document EP 0 383 374.
Cependant, alors que ce dispositif connu concerne spécifiquement un cadre publicitaire vertical, fermé par un couvercle léger, l'invention vise des applications différentes, et notamment celle dans laquelle le couvercle est un tampon de fonte obturant par exemple un regard de voirie. prévu dans une chaussée.However, while this known device relates specifically to a vertical advertising frame, closed by a light cover, the invention is aimed at different applications, and in particular that in which the cover is a cast iron plug closing off, for example, a manhole. provided in a roadway.
Deux problèmes se posent dans le type d'applications envisagées par l'invention, à savoir d'une part les difficultés de manipulation du couvercle, qui résultent directement du poids élevé et éventuellement de la disposition horizontale de ce dernier, et d'autre part la nécessité de prévenir les actes de vandalisme et notamment de se prémunir contre une ouverture non autorisée du couvercle.Two problems arise in the type of applications envisaged by the invention, namely on the one hand the difficulties of handling the lid, which result directly from the high weight and possibly from the horizontal arrangement of the latter, and on the other hand the need to prevent acts of vandalism and in particular to guard against unauthorized opening of the cover.
Le but de l'invention est précisément de proposer un dispositif susceptible de résoudre ces problèmes.The object of the invention is precisely to propose a device capable of solving these problems.
A cette fin, le dispositif de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci -dessus, est essentiellement caractérisé en ce que le bras et la douille de la clé sont sensiblement perpendiculaires l'un à l'autre, et en ce que le bras est sensiblement perpendiculaire au couvercle pour la position de déverrouillage de la clé. Grâce à cet agencement, le couvercle peut être soulevé par la clé en étant retenu par toute la surface latérale de la douille, et non simplement par deux ergots, comme c'est la cas suivant l'enseignement du document de brevet antérieur précité, cette solution étant inadaptée au cas de pièces de fonderie en raison de leur poids et de leurs tolérances de fabrication.To this end, the device of the invention, moreover conforming to the generic definition given in the preamble above, is essentially characterized in that the arm and the key socket are substantially perpendicular to each other, and in that the arm is substantially perpendicular to the cover for the unlocking position of the key. Thanks to this arrangement, the cover can be lifted by the key while being retained by the entire side surface of the sleeve, and not simply by two lugs, as is the case according to the teaching of the aforementioned prior patent document, this solution being unsuitable in the case of castings because of their weight and their manufacturing tolerances.
De plus, dans la mesure où la douille se trouve sensiblement parallèle au plan du couvercle, le mécanisme de verrouillage et de déverrouillage n'est pas directement visible, et reste inaccessible à des outils standard.Moreover, insofar as the sleeve is located substantially parallel to the plane of the lid, the locking and unlocking mechanism is not directly visible, and remains inaccessible to standard tools.
Dans ces conditions, il est par exemple possible de faire en sorte que' l'ouverture donne accès à une cavité du couvercle dans laquelle débouche un orifice, et que l'ouverture présente une forme en "L" dont une branche, perpendiculaire à l'orifice, autorise la clé à passer de l'une quelconque de ses positions de verrouillage et de déverrouillage à l'autre dès lors que la douille est insérée dans l'orifice, et interdise une translation du bras parallèlement à l'orifice dès lors que le bras est sensiblement perpendiculaire au couvercle alors que la douille est insérée dans '1 'orifice.Under these conditions, it is for example possible to ensure that the opening gives access to a cavity of the cover into which an orifice opens, and that the opening has an "L" shape, one branch of which is perpendicular to the orifice, authorizes the key to pass from any one of its locking and unlocking positions to the other as soon as the sleeve is inserted into the orifice, and prohibits a translation of the arm parallel to the orifice from then on that the arm is substantially perpendicular to the lid while the sleeve is inserted into '1 hole.
La cavité présente avantageusement une première paroi conformée en plan incliné et assurant le guidage de la douille dans la cavité. Pour rendre encore plus aisée la manipulation du couvercle au moyen de la clé, cette dernière comporte de préférence une poignée solidaire du bras, sensiblement parallèle à la douille, et disposée en regard de celle-ci.The cavity advantageously has a first wall shaped as an inclined plane and guiding the sleeve in the cavity. To make manipulation of the cover even easier by means of the key, the latter preferably comprises a handle integral with the arm, substantially parallel to the sleeve, and arranged facing the latter.
L'orifice précité peut être formé dans une seconde paroi, orthogonale à la première paroi, un axe portant le pêne pouvant alors être disposé dans l'orifice. La douille précitée peut comporter une nervure interne axiale apte à coopérer avec une rainure axiale ménagée sur l'axe portant le pêne.The aforementioned orifice can be formed in a second wall, orthogonal to the first wall, an axis carrying the bolt then being able to be placed in the orifice. The aforementioned sleeve may comprise an axial internal rib capable of cooperating with an axial groove made on the axis carrying the bolt.
Par ailleurs, la douille de la clé comporte de préférence, au niveau de sa partie débouchante, deux ergots externes opposés susceptibles de coopérer avec des nervures de guidage au fond de la cavité précitée et de traverser l'orifice précité dont le bord comporte des encoches de forme correspondant auxdits ergots. L'axe portant le pêne est par exemple monté tournant sur une oreille parallèle à la paroi précitée comportant l'orifice et comporte un méplat pour solidariser en rotation l'axe et le pêne qui présente une forme d'équerre.Furthermore, the socket of the key preferably comprises, at its emerging part, two opposite external lugs capable of cooperating with guide ribs at the bottom of the aforementioned cavity and of passing through the aforementioned orifice, the edge of which comprises notches. of shape corresponding to said lugs. The axis carrying the bolt is for example rotatably mounted on a lug parallel to the aforementioned wall comprising the orifice and comprises a flat to secure in rotation the axis and the bolt which has a square shape.
De préférence, le pêne est élastiquement retenu par une branche de l'équerre sur l'oreille précitée et entre cette oreille et la paroi précitée avec orifice au moyen d'un ressort et de rondelles.Preferably, the bolt is elastically retained by a branch of the bracket on the aforementioned lug and between this lug and the aforementioned wall with orifice by means of a spring and washers.
L'autre branche de l'équerre formant le pêne est par exemple apte à coopérer avec une encoche formant gâche ménagée dans un longeron à l'intérieur du cadre.The other branch of the bracket forming the bolt is for example capable of cooperating with a notch forming a striker made in a spar inside the frame.
La branche de l'équerre retenue sur l'oreille comporte avantageusement un trou avec méplat coopérant avec le méplat précité sur l'axe d'entraînement en rotation du pêne.The branch of the bracket retained on the lug advantageously comprises a hole with a flat surface cooperating with the aforementioned flat surface on the axis for driving the bolt in rotation.

Un dispositif de verrouillage conforme à cette invention est tout particulièrement destiné à équiper un tampon, couvercle ou analogue 1 susceptible d'obturer un cadre, châssis ou analogue repéré en 2 sur les figures 5 à 8 et délimitant l'ouverture d'un regard de chaussée par exemple. Ce dispositif de verrouillage est actionnable par une clé repérée d'une manière générale en 3 sur les figures 1 et 5 à 12.A locking device according to this invention is particularly intended to equip a buffer, cover or the like 1 capable of closing off a frame, chassis or the like marked at 2 in FIGS. 5 to 8 and delimiting the opening of a manhole. pavement for example. This locking device is operable by a key marked generally at 3 in Figures 1 and 5 to 12.
Conformément à l'invention, la paroi supérieure la du tampon ou couvercle 1 comporte une ouverture 4 d'accès à la clé 3, cette ouverture débouchant d'une part vers l'extérieur du tampon 1 et d'autre part dans une cavité 5 au voisinage du fond de laquelle est monté le mécanisme de verrouillage comme décrit en détail plus loin.In accordance with the invention, the upper wall 1a of the buffer or lid 1 comprises an opening 4 for access to the key 3, this opening opening on the one hand towards the outside of the buffer 1 and on the other hand into a cavity 5 near the bottom of which is mounted the locking mechanism as described in detail below.
Comme cela apparaît clairement sur la figure 1, la clé 3 comporte une partie 6 formant poignée et une douille 7 raccordée à la poignée 6 par un bras 8.As clearly shown in Figure 1, the key 3 comprises a part 6 forming a handle and a socket 7 connected to the handle 6 by an arm 8.
Conformément à l'invention, la poignée 6 et la douille 7 s'étendent respectivement depuis les deux extrémités du bras 8 suivant deux directions orthogonales et de même sens.According to the invention, the handle 6 and the sleeve 7 extend respectively from the two ends of the arm 8 in two orthogonal directions and in the same direction.
Autrement dit l'axe X-X' de la douille 7 est sensiblement parallèle à la poignée 6 qui s ' étend dans la même direction que celle de ladite douille. L'ouverture 4 d'accès à la clé 3, tout particulièrement à la douille 7 de cette clé, est partiellement obturée par une platine ou analogue 9 qui confère à l'ouverture 4 une forme en L. En effet on voit sur les figures 1, 2, 5 et 7 notamment que l'ouverture 4 présente, suivant l'exemple de réalisation représenté, la forme d'un rectangle dont l'un des coins est obturé par la platine 9 qui présente une forme sensiblement carrée, de sorte que la partie restante et débouchante de l'ouverture 4 dans la paroi supérieure la du tampon 1 a sensiblement la forme d'un L dans lequel pourra bien sûr être introduite et manoeuvrée la clé 3 comme on le décrira ultérieurementIn other words, the X-X' axis of sleeve 7 is substantially parallel to handle 6 which extends in the same direction as that of said sleeve. The opening 4 for access to the key 3, more particularly to the socket 7 of this key, is partially closed off by a plate or the like 9 which gives the opening 4 an L-shape. 1, 2, 5 and 7 in particular that the opening 4 has, according to the embodiment shown, the shape of a rectangle, one of the corners of which is closed off by the plate 9 which has a substantially square shape, so that the remaining and emerging part of the opening 4 in the upper wall 1a of the cover 1 has substantially the shape of an L in which the key 3 can of course be introduced and operated as will be described later
La cavité 5 associée au tampon 1, et située en dessous de la platine 9, comporte une paroi 10 en forme de plan incliné qui assure le guidage de la douille 7 de la clé 3 dans ladite cavité. Cette cavité 5 comporte également une paroi 11, bien visible sur les figures 3, 6 et 8 et qui est orthogonale à la paroi 10 en forme de plan incliné.The cavity 5 associated with the buffer 1, and located below the plate 9, comprises a wall 10 in the form of an inclined plane which ensures the guidance of the socket 7 of the key 3 in said cavity. This cavity 5 also includes a wall 11, clearly visible in Figures 3, 6 and 8 and which is orthogonal to the wall 10 in the form of an inclined plane.
La paroi 11 comporte un orifice 12 au travers duquel peut passer la douille 7 de la clé 3, de sorte que ladite douille peut alors venir en prise avec un axe 13 monté tourillonnant sur une oreille 14 solidaire du tampon 1, et portant un pêne repéré d'une manière générale en 15.The wall 11 has an orifice 12 through which the sleeve 7 of the key 3 can pass, so that said sleeve can then come into engagement with a pin 13 pivotally mounted on a lug 14 integral with the buffer 1, and carrying a bolt marked generally in 15.
Dans le fond de la cavité 5 sont prévues des nervures de guidage opposées 16. Une fois la douille 7 de la clé introduite dans la cavité 5, les nervures 16 constituent un moyen de butée et de guidage en translation de la douille 7 de la clé 3 par 1 ' intermédiaire de deux ergots externes et opposés 17 prévus extérieurement au niveau de la partie débouchante 7a de ladite douille 7. L'orifice 12 ménagé dans la paroi 11 de la cavité 5 comporte dans son bord des encoches 18 de forme correspondant aux ergots 17 de la douille 7 de façon à laisser le passage à ladite douille et permettre sa venue en prise avec l'axe 13 portant le pêne 15. En plus des ergots 17, la douille 7 comporte une nervure interne et axiale bien visible en 19 sur la figure 1.In the bottom of the cavity 5 are provided opposite guide ribs 16. Once the socket 7 of the key has been inserted into the cavity 5, the ribs 16 constitute a means of abutment and of guiding in translation of the socket 7 of the key. 3 by means of two external and opposite lugs 17 provided externally at the level of the emerging part 7a of said sleeve 7. The orifice 12 formed in the wall 11 of the cavity 5 comprises in its edge notches 18 of shape corresponding to the lugs 17 of sleeve 7 so as to allow said sleeve to pass through and allow it to come into engagement with pin 13 carrying bolt 15. In addition to the lugs 17, the sleeve 7 has an internal and axial rib clearly visible at 19 in Figure 1.
Cette nervure peut coopérer avec une rainure axiale 20 de forme correspondante ménagée sur l'axe 13 qui porte et entraîne le pêne 15, lorsqu'on manoeuvre la clé 3.This rib can cooperate with an axial groove 20 of corresponding shape provided on the axis 13 which carries and drives the bolt 15, when the key 3 is operated.
Cet axe 13 est monté tournant dans un orifice 21 prévu dans l'oreille 14 et situé dans l'axe de l'orifice 12 ménagé dans la paroi 11 de la cavité 5 et donnant accès à la douilleThis pin 13 is rotatably mounted in an orifice 21 provided in the lug 14 and located in the axis of the orifice 12 made in the wall 11 of the cavity 5 and giving access to the socket
7 de la clé 3, comme on l'expliquera en détail plus loin. Comme on le voit bien sur les figures 3, 6 et 8 notamment, l'oreille 14 est parallèle à la paroi 11, et entre l'oreille et la paroi peut tourner le pêne 15 qui présente la forme d'une équerre, suivant l'exemple de réalisation représenté. L'une 15a des branches de l'équerre comporte un orifice 22 avec méplat 23, de même que l'axe 13 d'entraînement du pêne 15 comporte un méplat 24. Ainsi, grâce aux deux méplats coopérants 23, 24 du pêne 15 et de l'axe 13, ce dernier peut entraîner en rotation le pêne lorsque la nervure 19 de la douille 7 appartenant à la clé 3 est en prise avec la rainure 20 de l'axe 13.7 of key 3, as will be explained in detail below. As clearly seen in Figures 3, 6 and 8 in particular, the lug 14 is parallel to the wall 11, and between the lug and the wall can turn the bolt 15 which has the shape of a bracket, according to the exemplary embodiment shown. One 15a of the arms of the bracket has an orifice 22 with flat 23, just as the axis 13 for driving the bolt 15 has a flat 24. Thus, thanks to the two cooperating flats 23, 24 of the bolt 15 and of the pin 13, the latter can drive the bolt in rotation when the rib 19 of the sleeve 7 belonging to the key 3 is in engagement with the groove 20 of the pin 13.
On a montré en 25 sur les figures 1, 6 et 8 notamment un empilement de rondelles avec ressort qui retient élastiquement, par l'intermédiaire d'une goupille 26, la branche 15a de l'équerre 15 sur l'oreille 14 entre cette oreille et la paroi 11 de la cavité 5 dans le tampon 1.There has been shown at 25 in FIGS. 1, 6 and 8 in particular a stack of washers with a spring which elastically retains, by means of a pin 26, the branch 15a of the bracket 15 on the lug 14 between this lug and the wall 11 of the cavity 5 in the pad 1.
L'autre branche 15b de l'équerre 15 constitue la partie active du pêne, en ce sens que c'est elle qui va coopérer positivement avec une encoche ou analogue repérée 27 sur les figures 5 et 7 et ménagée dans un longeron ou analogue 28 faisant saillie à l'intérieur du cadre 2.The other branch 15b of the bracket 15 constitutes the active part of the bolt, in the sense that it is this which will cooperate positively with a notch or the like marked 27 in FIGS. 5 and 7 and formed in a spar or the like 28 protruding inside the frame 2.
On a montré en 29 sur les figures 5 à 8 des butées d'assise du tampon 1 sur le cadre 2, ces butées étant au- dessus du longeron 28 comportant l'encoche formant gâche 27 à 1 ' intérieur du cadre 2. Pour faciliter la compréhension de l'invention, on décrira maintenant comment fonctionne le dispositif avec clé qui vient d'être décrit, en se reportant plus particulièrement aux figures 9 à 12. Comme on le voit sur les figures 1 et 9 , la douille 7 de la clé 3 est introduite par l'ouverture 4 dans la cavité 5, et cette introduction ne peut être faite que pour un seul sens de la clé, à savoir celui visible sur la figure 1. Plus précisément la douille 7 glisse sur la paroi 10 en forme de plan incliné de la cavité 5, jusqu'à ce que les ergots opposés 17 de la douille 7 viennent en butée sur les nervures 16 au fond de ladite cavité, comme on le voit sur la figure 10 et également sur les figures 5 et 6. Il faut remarquer que, dans cette position, la clé 3 est bloquée par son bras 8 entre le bord de l'ouverture 4 et le bord en vis-à-vis 9a de la platine 9.There has been shown at 29 in FIGS. 5 to 8 abutments for seating the buffer 1 on the frame 2, these abutments being above the spar 28 comprising the notch forming a striker plate 27 inside the frame 2. To facilitate understanding of the invention, we will now describe how the device with key which has just been described operates, with particular reference to FIGS. 9 to 12. As seen in Figures 1 and 9, the socket 7 of the key 3 is introduced through the opening 4 in the cavity 5, and this introduction can only be made for a single direction of the key, namely that visible in Figure 1. More precisely the sleeve 7 slides on the wall 10 in the form of an inclined plane of the cavity 5, until the opposite lugs 17 of the sleeve 7 come into abutment on the ribs 16 at the bottom of said cavity , as seen in Figure 10 and also in Figures 5 and 6. It should be noted that, in this position, the key 3 is blocked by its arm 8 between the edge of the opening 4 and the edge screw- opposite 9a of plate 9.
Etant ainsi immobilisée, la clé 3 ne peut être actionnée que par une translation par glissement des ergots 17 de la douille 7 sur les nervures 16 de la cavité 5, et cela jusqu'à ce que la douille, traversant l'orifice 12 de la paroi 11, vienne en prise avec l'axe 13 du pêne 15 par sa nervure 19 qui pénètre dans la rainure 20 de l'axe 13.Being thus immobilized, the key 3 can only be actuated by translation by sliding of the lugs 17 of the socket 7 on the ribs 16 of the cavity 5, and this until the socket, passing through the orifice 12 of the wall 11, comes into engagement with the pin 13 of the bolt 15 by its rib 19 which enters the groove 20 of the pin 13.
Il convient de préciser ici que la figure 9 montre le pêne 15 en position verrouillée dans l'encoche 27 du cadre 2.It should be specified here that Figure 9 shows the bolt 15 in the locked position in the notch 27 of the frame 2.
Lorsque la douille 7 se trouve donc en prise avec l'axeWhen the sleeve 7 is therefore in engagement with the axis
13 d'entraînement du pêne 15, comme on le voit bien sur les figures 7 et 8, le bras 8 de la clé 3 échappe à la position d'immobilisation décrite précédemment, dans l'une des branches du L que forme l'ouverture 4, pour venir au droit de l'autre branche du L, de sorte que la clé 3 peut être manoeuvrée en rotation, comme on le voit sur les figures 11 et 12 pour ainsi entraîner en rotation l'axe 13 et donc le pêne 15 qui peut se dégager par sa partie 15b de l'encoche 27 du cadre 2.13 for driving the bolt 15, as can be clearly seen in FIGS. 7 and 8, the arm 8 of the key 3 escapes the immobilization position described above, in one of the branches of the L formed by the opening 4, to come to the right of the other branch of the L, so that the key 3 can be operated in rotation, as seen in Figures 11 and 12 to thus rotate the axis 13 and therefore the bolt 15 which can be released by its part 15b from the notch 27 of the frame 2.
Le tampon 1 est donc "ouvert", et la clé 3 demeure accouplée à l'axe 13 et est maintenue, par son bras 8, prisonnière dans l'ouverture 4 (voir figure 12) ce qui permet, avec la clé 3, de soulever le tampon 1 hors du cadre 2.The buffer 1 is therefore "open", and the key 3 remains coupled to the axis 13 and is held, by its arm 8, prisoner in the opening 4 (see figure 12) which allows, with the key 3, to lift buffer 1 out of frame 2.
Le tampon 1 pourra bien sûr être remis en position de fermeture sur le cadre 2 avec la clé 3 qui reste prisonnière dans la cavité 5 en position déverrouillée du pêne 5. Pour verrouiller à nouveau le tampon 1 sur le cadre 2, il suffit de la faire basculer puis de la translater dans la cavité 5 suivant un sens opposé à celui décrit précédemment, de façon à pouvoir sortir la douille 7 de ladite cavité. II faut donc faire effectuer à la clé 3 dans la cavité 5 un mouvement de translation puis de rotation ou l'inverse pour respectivement déverrouiller ou verrouiller le tampon sur son cadre, et cela en passant de l'une des branches du L à l'autre que forme l'ouverture 4 avec sa platine associée 9. On a donc réalisé suivant l'invention un mécanisme pêne-gâche qui est invisible de l'extérieur et demeure inaccessible à moins d'utiliser la clé de forme spéciale selon cette invention. On comprend en effet qu'il sera impossible, sans utiliser cette clé, et même en utilisant une clé à douille coudée du commerce, d'aller chercher l'axe d'entraînement du pêne, c'est-à-dire d'introduire la douille en fond de cavité pour qu'elle soit exactement au droit de l'axe d'entraînement du pêne, afin de permettre la mise en prise de la douille avec ledit axe. On notera en passant que, sur la figure 7, qui représente la douille de la clé de l'invention en prise avec l'axe, alors que le pêne 15b est en position verrouillée, on a montré néanmoins, pour une meilleure compréhension, ledit pêne en traits pointillés pour illustrer comment, en position déverrouillée, il échappe à l'encoche 27 du longeron intérieur 28 appartenant au cadre 2. The buffer 1 can of course be returned to the closed position on the frame 2 with the key 3 which remains trapped in the cavity 5 in the unlocked position of the bolt 5. To lock buffer 1 again on frame 2, it suffices to tilt it then to translate it into cavity 5 in a direction opposite to that described previously, so as to be able to remove sleeve 7 from said cavity. It is therefore necessary to make the key 3 in the cavity 5 perform a movement of translation then of rotation or the reverse to respectively unlock or lock the buffer on its frame, and this by passing from one of the branches of the L to the other than forms the opening 4 with its associated plate 9. A bolt-latch mechanism has therefore been produced according to the invention which is invisible from the outside and remains inaccessible unless the special shaped key according to this invention is used. We understand that it will be impossible, without using this key, and even using a commercially available angled socket wrench, to get the drive shaft of the bolt, that is to say to introduce the socket at the bottom of the cavity so that it is exactly in line with the drive shaft of the bolt, in order to allow the socket to engage with said shaft. It will be noted in passing that, in FIG. 7, which represents the socket of the key of the invention in engagement with the axis, while the bolt 15b is in the locked position, it has nevertheless been shown, for a better understanding, said bolt in dotted lines to illustrate how, in the unlocked position, it escapes the notch 27 of the inner spar 28 belonging to the frame 2.
