Description

La présente invention concerne un water-closet du type à broyeur et comportant une chambre de broyage communiquant avec le fond de la cuvette du water-closet, la chambre contenant des moyens, notamment un rotor, en vue de provoquer, d'une part, la réduction des matières à évacuer en suspension dans l'eau et, d'autre part, leur mise en mouvement circulaire permettant, par un effet de pompe centrifuge, le refoulement de l'eau et des matières en suspension et leur évacuation vers l'extérieur.The present invention relates to a water closet of the grinder type and comprising a grinding chamber communicating with the bottom of the bowl of the water closet, the chamber containing means, in particular a rotor, with a view to causing, on the one hand, the reduction of the materials to be evacuated in suspension in the water and, on the other hand, their circular movement allowing, by a centrifugal pump effect, the discharge of the water and the suspended solids and their evacuation towards the outside.

Les water-closets à évacuation forcée de ce type, comme dans le brevet US-A No 3259917, présentent des avantages notables; pour une consommation d'énergie pratiquement nulle, ils permettent d'installer un poste de toilette avec siège de water-closet dans des endroits qui ne se trouvent pas reliés à une évacuation de grand diamètre du type tout-à-l'égout.Forced evacuation water closets of this type, as in US-A No. 3259917, have notable advantages; for practically zero energy consumption, they make it possible to install a toilet station with water closet seat in places that are not connected to a large-diameter drainage of the sewerage type.

Le refoulement des matières en suspension dans l'eau étant propulsé mécaniquement, on peut disposer de telles installations en contrebas, par exemple dans une cave ou dans des endroits où la conduite d'évacuation doit remonter pour passer un seuil ou encore lorsque le poste sanitaire est loin de son point d'évacuation.The discharge of the suspended matter in the water being mechanically propelled, it is possible to have such installations below, for example in a cellar or in places where the evacuation pipe must go up to pass a threshold or even when the sanitary station is far from its point of evacuation.

En outre, les appareils de ce type nécessitent une consommation extrêmement réduite d'eau par rapport aux installations de toilette à évacuation par chasse d'eau.In addition, devices of this type require an extremely reduced consumption of water compared to flushing toilet installations.

Les dispositifs à broyeur présentent cependant des inconvénients lorsque, comme c'est fréquem- ment le cas, les utilisateurs se servent du poste sanitaire pour évacuer des matières non broyables.However, grinder devices have drawbacks when, as is often the case, users use the sanitary station to evacuate non-grindable materials.

Cela se rencontre souvent dans les collectivités, hôtels, lieux publics, etc.: l'utilisateur, de passage ou irresponsable, ou encore ignorant les conditions spécifiques d'utilisation d'une évacuation à broyeur, a tendance à se débarrasser d'objets divers qui sont souvent mal «digérés» par l'appareil.This is often found in communities, hotels, public places, etc .: the user, transient or irresponsible, or even ignoring the specific conditions for using a waste disposal system, tends to get rid of various objects which are often poorly "digested" by the device.

On assiste alors à des accidents tels que le blocage fréquent du rotor, la rupture de certaines des pièces du rotor; on voit également des organes ou des corps étrangers qui ont pu être refoulés dans la canalisation d'évacuation par le broyeur se trouver bloqués dans un coude ou un rétreint de la canalisation d'évacuation et provoquer l'obturation de cette dernière, accident d'autant plus difficile à réparer qu'il est pratiquement impossible de détecter à quel endroit la canalisation se trouve ainsi bouchée.We then witness accidents such as frequent blocking of the rotor, rupture of some of the parts of the rotor; we also see organs or foreign bodies that may have been forced back into the evacuation pipe by the crusher find themselves blocked in an elbow or a constriction of the evacuation pipe and cause the obturation of the latter, accident of all the more difficult to repair since it is practically impossible to detect where the pipe is thus blocked.

Dans le cas, moins grave, où l'obturation se situe au niveau du broyeur, la réparation est néanmoins délicate, car elle nécessite le démontage de l'ensemble du broyeur qui est situé sous la cuvette ou en partie arrière et qui n'est pas facilement accessible.In the less serious case, where the obturation is at the level of the crusher, the repair is nevertheless delicate, because it requires the disassembly of the whole of the crusher which is located under the bowl or at the rear and which is not not easily accessible.

Dans ces conditions, les dispositifs connus visant à empêcher l'entraînement de corps étrangers vers la conduite d'évacuation de petit diamètre, qui sont par exemple constitués d'un panier formant filtrage situé dans la chambre de broyage et permettant le passage des matières broyées mais non des corps durs ou étrangers, ne donnent pas satisfaction dans la mesure où il reste nécessaire, en cas de jet par l'utilisateur d'un corps dur dans la cuvette, de démonter l'ensemble du broyeur, depuis la face arrière et la partie inférieure de la cuvette, afin d'accéder à la chambre de broyage, et de dégager de l'intérieur du panier le corps étranger.Under these conditions, the known devices aiming at preventing the entrainment of foreign bodies towards the evacuation pipe of small diameter, which for example consist of a basket forming filtering located in the grinding chamber and allowing the passage of the crushed materials. but not hard or foreign bodies, are not satisfactory insofar as it remains necessary, in the event of the user throwing a hard body into the bowl, to dismantle the whole of the crusher, from the rear face and the lower part of the bowl, in order to access the grinding chamber, and to clear the interior of the basket of the foreign body.

L'invention vise à remédier à ces inconvénients et permet d'assurer des conditions de parfaite efficacité au dispositif d'évacuation de cuvette de water-closet par entraînement forcé, notamment par broyeur.The invention aims to remedy these drawbacks and makes it possible to ensure conditions of perfect efficiency for the device for removing the water closet bowl by forced drive, in particular by grinder.

L'invention évite, d'une part, l'entraînement vers la conduite d'évacuation de corps qui risqueraient de provoquer une obturation de cette conduite; et, au cas où un tel corps aurait été jeté et serait resté dans la chambre de broyage, l'invention permet de le retirer immédiatement et sans difficulté en évitant toute opération de démontage long, fastidieux et délicat nécessairement réservée à un professionnel.The invention avoids, on the one hand, the drive towards the body evacuation pipe which would risk causing a blockage of this pipe; and, in the event that such a body has been thrown away and has remained in the grinding chamber, the invention makes it possible to remove it immediately and without difficulty, avoiding any long, tedious and delicate dismantling operation necessarily reserved for a professional.

A cet effet, l'invention concerne un water-closet du type constitué d'une cuvette alimentée en eau et dont le fond communique par un passage avec une chambre inférieure munie de moyens amovibles de broyage et d'entraînement des matières vers un conduit d'évacuation, caractérisé en ce que lesdits moyens amovibles de broyage et d'entraînement, d'une part, et le passage entre la cuvette et ladite chambre de broyage, d'autre part, sont prévus avec une configuration et des dimensions permettant le déplacement desdits moyens de broyage et d'entraînement depuis la chambre de broyage vers le fond de la cuvette, à travers ledit passage en permettant ainsi d'accéder aux moyens de broyage et d'entraînement depuis le fond de la cuvette et de procéder au démontage, au retrait et au remontage desdits moyens par la face ouverte de la cuvette.To this end, the invention relates to a water closet of the type consisting of a bowl supplied with water and the bottom of which communicates by a passage with a lower chamber provided with removable means for grinding and driving the materials towards a conduit d evacuation, characterized in that said removable grinding and driving means, on the one hand, and the passage between the bowl and said grinding chamber, on the other hand, are provided with a configuration and dimensions allowing movement said grinding and driving means from the grinding chamber towards the bottom of the bowl, through said passage, thereby allowing access to the grinding and driving means from the bottom of the bowl and to dismantling, the removal and reassembly of said means by the open face of the bowl.

De préférence, le passage entre la cuvette et la chambre inférieure ou chambre de broyage est partiellement obturé, en position de fonctionnement, par une cloison d'obturation amovible et verrouillable sur le fond de la cuvette, cette cloison étant pourvue sensiblement en son centre d'une ouverture de diamètre limité pour permettre l'évacuation de l'eau d'entraînement et des matières depuis l'espace intérieur de la cuvette vers la chambre de broyage.Preferably, the passage between the bowl and the lower chamber or grinding chamber is partially closed, in the operating position, by a removable and lockable closure partition on the bottom of the bowl, this partition being provided substantially at its center. an opening of limited diameter to allow the evacuation of the entrainment water and of the materials from the interior space of the bowl towards the grinding chamber.

D'autres caractéristiques et avantages de l'invention ressortiront encore de la description qui suit et qui est donnée en rapport avec une forme de réalisation particulière présentée à titre d'exemple non limitatif et en se référant aux dessins annexés.

  • La fig. 1 représente une vue en coupe longitudinale de la cuvette de water-closet et du broyeur associé selon l'invention.
  • La fig. 2 représente une vue en plan de ladite cuvette.
Other characteristics and advantages of the invention will emerge from the description which follows and which is given in relation to a particular embodiment presented by way of nonlimiting example and with reference to the appended drawings.
  • Fig. 1 shows a view in longitudinal section of the water closet bowl and of the associated mill according to the invention.
  • Fig. 2 shows a plan view of said bowl.

Selon les figures, le siège comporte une cuvette 1 alimentée en eau par tout dispositif convenable, et notamment par le dispositif à effet antiaspiration tel que décrit dans la demande de brevet français déposée ce jour par la titulaire.According to the figures, the seat comprises a bowl 1 supplied with water by any suitable device, and in particular by the device with anti-suction effect as described in the French patent application filed today by the owner.

La cuvette est de forme extérieure traditionnelle; son fond 2 présente en partie basse une solution de continuité définie par les bords 3, 3' de contour circulaire.The bowl is of traditional exterior shape; its bottom 2 has in the lower part a continuity solution defined by the edges 3, 3 ′ of circular outline.

La solution de continuité 2 prévue sur le fond de la cuvette occupe un diamètre sensiblement égal à la moitié de la longueur de ladite cuvette. Cette valeur n'étant pas caractéristique, il reste nécessaire que la solution de continuité permette, ainsi qu'on l'exposera plus loin, le passage et l'enlèvement des moyens de broyage et d'entraînement depuis l'intérieur de la cuvette de façon à permettre la maintenance et l'entretien de l'appareil et la réparation de tous les accidents décrits ci-dessus, notamment la présence non désirée de corps durs ayant pénétré dans la chambre de broyage et d'évacuation.The continuity solution 2 provided on the bottom of the bowl occupies a diameter substantially equal to half the length of said bowl. As this value is not characteristic, it remains necessary that the continuity solution allows, as will be explained below, the passage and removal of the grinding and drive means from inside the bowl. so as to allow the maintenance and upkeep of the apparatus and the repair of all the accidents described above, in particular the unwanted presence of hard bodies having entered the grinding and evacuation chamber.

Sous la paroi inférieure de la cuvette 1, et immédiatement sous les bords 3 de la solution de continuité 2, est positionné un boîtier de forme générale cylindrique 4 dont les bords supérieurs verticaux 5 viennent s'ajuster immédiatement sous les bords 3 de la solution de continuité de la cuvette, un joint d'étanchéité 6 étant interposé.Under the lower wall of the bowl 1, and immediately under the edges 3 of the continuity solution 2, is positioned a generally cylindrical case 4 whose vertical upper edges 5 come to fit immediately under the edges 3 of the solution of continuity of the bowl, a seal 6 being interposed.

Le boîtier 4 qui est ouvert sur sa partie supérieure constitue et définit la chambre de broyage 26.The housing 4 which is open on its upper part constitutes and defines the grinding chamber 26.

Le fond 7 du boîtier est solidaire par un jeu d'écrou et boulon 8, 8' du moteur électrique 9.The bottom 7 of the housing is secured by a set of nuts and bolts 8, 8 'to the electric motor 9.

L'axe d'entraînement 10 venu du moteur 9 traverse le fond 7 du boîtier 4 et déborde à l'intérieur de la chambre de broyage pour recevoir le rotor 11.The drive shaft 10 coming from the motor 9 crosses the bottom 7 of the housing 4 and overflows inside the grinding chamber to receive the rotor 11.

Le rotor 11 est constitué par un disque 12 dont le centre est associé à une cuvette renversée, l'ouverture étant tournée vers le bas, et cette cuvette 13 est apte à être emboîtée sur le pivot constitué par l'extrémité de l'arbre tournant 10.The rotor 11 is constituted by a disc 12 whose center is associated with an inverted cup, the opening being turned downwards, and this cup 13 is capable of being fitted on the pivot formed by the end of the rotating shaft 10.

Le disque 12 comporte à sa périphérie des palettes radiales 14 et 14' de type connu et permettant l'entraînement en rotation de l'ensemble fluide contenu à l'intérieur de la chambre de broyage et l'évacuation par la conduite 15 raccordée tangentiellement à la base de la chambre de broyage, de façon connue.The disc 12 has, at its periphery, radial vanes 14 and 14 ′ of known type and allowing the fluid assembly contained in the grinding chamber to be rotated and evacuated by the pipe 15 tangentially connected to the base of the grinding chamber, in a known manner.

Des moyens d'étanchéité connus 16 sont disposés sur l'arbre tournant 10 de façon à éviter toute fuite de liquide depuis la chambre de broyage 26 vers le moteur; sous le fond 7 du boîtier, et sur l'arbre 10, on a en outre interposé une rondelle ou disque de protection 17, qui est montée solidaire de l'axe 10 et s'oppose à l'écoulement de liquide le long de l'arbre, la mise en rotation du moteur, à l'occasion de chaque fonctionnement de l'appareil, assurant la projection vers l'extérieur des quelques gouttelettes qui auraient pu accidentellement s'infiltrer depuis le fond du boîtier et le long de l'arbre 10.Known sealing means 16 are arranged on the rotating shaft 10 so as to prevent any leakage of liquid from the grinding chamber 26 towards the engine; under the bottom 7 of the housing, and on the shaft 10, there is also interposed a washer or protective disc 17, which is mounted integral with the axis 10 and opposes the flow of liquid along the 'shaft, the rotation of the motor, during each operation of the device, ensuring the projection towards the outside of the few droplets which could have accidentally infiltrated from the bottom of the case and along the tree 10.

La solution de continuité 2 par laquelle la cuvette 1 communique avec la chambre de broyage 26 (constituée par le boîtier 4) est occupée, en position de fonctionnement, par une cloison d'obturation partielle 18 (interrompue en son centre par un jeu de fentes radiales 32, 33, 34) rendue solidaire de la jupe verticale 19 qui pénètre dans la chambre de broyage sensiblement jusqu'au niveau du disque 12.The continuity solution 2 by which the bowl 1 communicates with the grinding chamber 26 (constituted by the housing 4) is occupied, in the operating position, by a partial closure partition 18 (interrupted in its center by a set of slots radials 32, 33, 34) made integral with the vertical skirt 19 which penetrates into the grinding chamber substantially up to the level of the disc 12.

La jupe 19 et le disque 12 sont pourvus de perforations formées de crevés dans la paroi, de préférence métallique, respectivement de la jupe et du disque, et ces crevés 28, 29, 30, 31 sont rabattus vers l'intérieur de la chambre; ainsi ces crevés constituent, d'une part, des aspérités qui facilitent l'opération de réduction et de dilacération des matières entraînées en rotation dans la chambre de broyage et projetées par conséquent contre la paroi de la jupe, l'ensemble formant ainsi une râpe; et, d'autre part, ces crevés définissent des ouvertures, de calibre déterminé, permettant le passage de l'eau chargée de matières en suspension, tout en s'opposant au passage, depuis l'intérieur de la chambre vers l'évacuation 15, de corps durs ou étrangers qui risqueraient d'obturer la canalisation de sortie 15.The skirt 19 and the disc 12 are provided with perforations formed in the wall, preferably metallic, of the skirt and the disc respectively, and these punctures 28, 29, 30, 31 are folded towards the interior of the chamber; thus these punctures constitute, on the one hand, asperities which facilitate the operation of reduction and shredding of the materials entrained in rotation in the grinding chamber and consequently projected against the wall of the skirt, the assembly thus forming a rasp ; and, on the other hand, these punctures define openings, of determined size, allowing the passage of water laden with suspended matter, while opposing the passage, from inside the chamber towards the discharge 15 , hard or foreign bodies which could block the outlet pipe 15.

Ainsi, le disque 12 et la jupe 19 forment, d'une part, une râpe rendant particulièrement efficace et rapide le broyage et, d'autre part, définissant un panier de filtration ou dégrilleur s'opposant au passage de corps parasites.Thus, the disc 12 and the skirt 19 form, on the one hand, a rasp making grinding particularly efficient and rapid and, on the other hand, defining a filtration basket or screen opposing the passage of parasitic bodies.

L'ensemble cloison d'obturation partielle 18 et jupe 19 est inséré de façon amovible à l'intérieur du boîtier constituant la chambre de broyage et peut être bloqué en position, par exemple par insertion des lames radiales 20 sous les butées 21, l'ensemble définissant un système de fixation amovible de type à baïonnette.The assembly of partial closure partition 18 and skirt 19 is removably inserted inside the housing constituting the grinding chamber and can be locked in position, for example by insertion of the radial blades 20 under the stops 21, the assembly defining a removable bayonet type fixing system.

Il est ainsi particulièrement facile de dégager l'ensemble constitué par la jupe 19 et la paroi supérieure 18 par simple mouvement de rotation et enlèvement vers le haut.It is thus particularly easy to disengage the assembly constituted by the skirt 19 and the upper wall 18 by simple movement of rotation and removal upwards.

On accède ainsi à l'intérieur de la chambre de broyage, ce qui permet déjà de retirer très aisément tout corps étranger qui se serait inséré ou serait tombé ou malencontreusement jeté dans la cuvette 1.This gives access to the interior of the grinding chamber, which already makes it very easy to remove any foreign body which has been inserted or has fallen or inadvertently been thrown into the bowl 1.

Pareillement, après enlèvement de la jupe 19 avec la paroi supérieure 18, il est facile de retirer, toujours par dégagement vertical vers le haut, l'ensemble constitué par le rotor 11 emmanché sur le pivot 10.Likewise, after removal of the skirt 19 with the upper wall 18, it is easy to remove, still by vertical release upwards, the assembly constituted by the rotor 11 fitted on the pivot 10.

Cela permet une opération rapide de nettoyage chaque fois que cela sera nécessaire, quelques minutes suffisant à opérer l'enlèvement et la remise en place des deux organes de broyage et d'entraînement, à savoir la jupe fixe 19 et le rotor 11.This allows a rapid cleaning operation whenever necessary, a few minutes sufficient to carry out the removal and replacement of the two grinding and drive members, namely the fixed skirt 19 and the rotor 11.

On a avantageusement prévu en outre que l'ouverture centrale située sur la paroi d'obturation partielle 18 et par laquelle le fond de la cuvette communique avec la chambre de broyage 26, lorsque ladite paroi 18 et la jupe 19 sont en position de fonctionnement, peut être également partiellement obturée par un diaphragme de type connu et constitué par exemple par un voile de matière souple telle que le caoutchouc parcouru par des fentes radiales se rejoignant dans leur centre, l'ensemble définissant des lèvres en V susceptibles de s'écarter sous la pression dynamique du fluide lorsque ce dernier est entraîné par le rotor, et ramené immédiatement ensuite en position de fermeture.Advantageously, provision has also been made for the central opening situated on the partial closure wall 18 and through which the bottom of the bowl communicates with the grinding chamber 26, when said wall 18 and the skirt 19 are in the operating position, can also be partially closed by a diaphragm of known type and constituted for example by a veil of flexible material such as rubber traversed by radial slots joining in their center, the assembly defining lips in V likely to deviate under the dynamic pressure of the fluid when the latter is driven by the rotor, and immediately returned to the closed position.

Outre l'esthétique avantageuse qu'il procure à l'ensemble, ce diaphragme souple d'obturation évite toute projection parasite accidentelle lorsque le rotor est en fonctionnement.In addition to the advantageous aesthetics which it provides to the assembly, this flexible shutter diaphragm avoids any accidental spurious projection when the rotor is in operation.

Il joue un rôle de protection en évitant la tentation de pénétration, par exemple manuelle, lorsque l'ensemble est en fonctionnement.It plays a protective role by avoiding the temptation to penetrate, for example manual, when the assembly is in operation.

Le diaphragme souple joue également, ainsi que les expérimentations l'ont démontré, un rôle important en tant qu'écran antibruit procurant un fonctionnement particulièrement silencieux de l'ensemble; on comprend en effet que les vibrations sonores qui sont liées à la mise en rotation du milieu fluide dans la chambre de broyage et à son évacuation par le conduit 15, vibrations qui se développent dans la chambre de broyage, sont étouffées par la présence du diaphragme souple d'autant que, même lorsque les lèvres du diaphragme sont écartées, elles le sont sous la pression du fluide de sorte que l'espace entre les lèvres, en position d'écartement vers le bas, est en réalité occupé par le milieu liquide en position d'évacuation; l'ensemble constitue ainsi un écran solide et liquide s'opposant au passage des vibrations sonores et permettant d'obtenir un fonctionnement particulièrement silencieux.The flexible diaphragm also plays, as experiments have shown, an important role as a noise barrier providing particularly silent operation of the assembly; it is in fact understood that the sound vibrations which are linked to the rotation of the fluid medium in the grinding chamber and to its evacuation through the conduit 15, vibrations which develop in the grinding chamber, are stifled by the presence of the diaphragm flexible as much as, even when the lips of the diaphragm are spaced apart, they are spaced apart under the pressure of the fluid so that the space between the lips, in the position of spacing downwards, is actually occupied by the liquid medium in the evacuation position; the assembly thus constitutes a solid and liquid screen opposing the passage of sound vibrations and making it possible to obtain particularly silent operation.

De façon connue, l'alimentation en eau est obtenue par une électrovanne dont le fonctionnement est couplé avec le fonctionnement du moteur, de sorte que l'arrivée d'eau précède la mise en fonctionnement du rotor et se prolonge au-delà de l'arrêt du rotor en assurant ainsi le maintien d'une certaine quantité d'eau dans le fond de la cuvette.In known manner, the water supply is obtained by a solenoid valve, the operation of which is coupled with the operation of the engine, so that the supply of water precedes the operation of the rotor and extends beyond the stopping the rotor, thereby ensuring that a certain amount of water is maintained in the bottom of the bowl.

La fixation de l'ensemble boîtier 4 et moteur 9 peut être obtenue partout moyen; dans l'exemple illustré au dessin, la fixation de l'ensemble boîtier et moteur est obtenue par une vis de blocage inférieure 22 formant vérin de réglage de la mise à hauteur et dont le serrage repousse le moteur vers le haut, ce dernier repoussant à son tour le boîtier qui se trouve ainsi plaqué contre les bords 3 du fond de la cuvette en assurant la pression sur les moyens d'étanchéité 6.The attachment of the housing 4 and motor 9 assembly can be obtained everywhere; in the example illustrated in the drawing, the fixing of the housing and motor assembly is obtained by a lower locking screw 22 forming a jack for adjusting the height adjustment and the tightening of which pushes the motor upwards, the latter repelling in turn the housing which is thus pressed against the edges 3 of the bottom of the bowl while ensuring the pressure on the sealing means 6.

En cas de nécessité, il est facile, par desserrage de la vis 22, de dégager l'ensemble.If necessary, it is easy, by loosening the screw 22, to release the assembly.

La cuvette ainsi réalisée, obturée par la paroi 18 et le diaphragme 23, présente un fond d'aspect continu formant un bassin; et la cuvette peut ainsi être utilisée comme bidet; à cet effet, le fond sensiblement vertical 24 de la cuvette peut comporter une buse 25 éventuellement orientable, procurant un jet directionnel pour les ablutions intimes.The bowl thus produced, closed by the wall 18 and the diaphragm 23, has a bottom of continuous appearance forming a basin; and the bowl can thus be used as a bidet; for this purpose, the substantially vertical bottom 24 of the bowl may comprise a nozzle 25 which may be adjustable, providing a directional jet for intimate ablutions.

Dans l'exemple de réalisation du dispositif selon l'invention, le moteur est fixé à l'embase de l'ensemble, et l'accès à la chambre de broyage est effectué par enlèvement de la jupe 19 et de la paroi supérieure 18. On comprend qu'il est possible, sans sortir du cadre de l'invention, de concevoir la cuvette, la chambre de broyage et le moteur sous la forme d'un ensemble unitaire amovible, introduit dans un réceptacle (à paroi cylindrique ou conique) par son ouverture supérieure, ledit réceptacle étant alors solidaire de l'embase 27. Cette disposition permet un accès encore plus aisé, notamment au moteur.In the embodiment of the device according to the invention, the motor is fixed to the base of the assembly, and access to the grinding chamber is carried out by removing the skirt 19 and the upper wall 18. We understand that it is possible, without departing from the scope of the invention, to design the bowl, the grinding chamber and the motor in the form of a removable unitary assembly, introduced into a receptacle (with cylindrical or conical wall) by its upper opening, said receptacle then being secured to the base 27. This arrangement allows even easier access, in particular to the engine.
