Abstract

The inspection hatch comprises a frame (1) which covers the opening and an opening frame (12) edging the closing slab (9). Both frames have corner irons whose vertical flanges (8,14) converge toward each other to define a trapezoidal intermediate space sealed in its upper part by a perimeter joint (21). The two frames are immobilized relative to each other by several locking devices each comprising a fold down handle (31) which also forms a means for lifting the slab held in the opening frame.

Description

La présente invention concerne une trappe de visite présentant une étanchéité renforcée.The present invention relates to a hatch visit with a reinforced seal.

Elle se rapporte notamment et plus spécifiquement à une trappe de visite pour un sol notamment carrelé.It relates in particular and more specifically to an inspection hatch for a floor especially tiled.

Les trappes de sol sont prévues dans le sol des pièces ou locaux les plus bas. Elles ont pour but de donner accès au domaine souterrain dans lequel passent les canalisations et les liaisons et raccordements techniques divers d'une habitation et plus fréquemment d'un local, d'une surface de vente, d'un entrepôt, d'un atelier, d'un laboratoire ou autres.Floor hatches are provided in the ground lowest rooms or premises. They aim to give access to the underground domain in which pass the pipes and connections and various technical connections of a dwelling and more frequently from a local, a sales area, warehouse, workshop, laboratory or other.

Les plaques de sol doivent satisfaire simultanément à plusieurs conditions de base et en plus à certaines conditions particulières ou optionnelles.The floor plates must satisfy simultaneously with several basic conditions and in addition under certain special or optional conditions.

Ainsi, la trappe entière mais plus précisément la plaque de fermeture doit être particulièrement résistante pour ne pas fléchir sous les charges momentanées et occasionnelles telles que celles provoquées par le passage de véhicules, en particulier de chariots élévateurs, d'engins de toute sorte, mais aussi de voitures et camionnettes.So the whole hatch but more precisely the closing plate must be particularly resistant so as not to flex under momentary and occasional loads such as those caused by the passage of vehicles, in particular of forklifts, machines of all so, but also cars and vans.

Par ailleurs, l'étanchéité doit être assurée notamment aux liquides pour éviter la traversée des produits de nettoyage, mais aussi aux gaz pour empêcher la remontée des mauvaises odeurs et la transmission des gaz et fumées.Furthermore, sealing must be ensured especially with liquids to avoid crossing cleaning products but also gas to prevent the rise of bad odors and the transmission of gas and smoke.

De plus, il importe de pouvoir confondre esthétiquement le dessus de la plaque dans l'ensemble de la surface carrelée en assurant la continuité des lignes de joint même au niveau des chants des cadres de la trappe devant ressortir en lignes fines analogues à celles des joints. In addition, it is important to be able to confuse aesthetically the top of the plate as a whole of the tiled surface ensuring continuity of joint lines even at the edges of the frames of the hatch should come out in fine lines similar to those of the joints.

De plus, la plaque de fermeture de la trappe doit pouvoir être soulevée sans difficulté excessive malgré son poids important. A cet effet, l'encrassement doit être réduit au minimum et les moyens de préhension techniquement au point et faciles à mettre en oeuvre.In addition, the hatch closing plate must be capable of being lifted without undue difficulty despite its significant weight. For this purpose, fouling should be minimized and the means of gripping technically developed and easy to use.

De plus, dans certaines applications l'étanchéité doit être renforcée et il y a lieu d'apporter une garantie de non-contamination biologique.In addition, in some applications sealing must be reinforced and there is a need provide a guarantee of non-contamination organic.

Sur le plan esthétique et pose du carrelage, la surface supérieure de la trappe doit être plate et uniforme sans nécessiter de découpe spéciale des carreaux. Cette condition doit être satisfaite par l'absence de fixations apparentes.On the aesthetic level and laying of tiles, the upper surface of the hatch must be flat and uniform without requiring special cutting of tiles. This condition must be satisfied by the absence of visible fixings.

Finalement, le montage de la trappe de sol doit pouvoir s'effectuer de façon aisée et rapide.Finally, the assembly of the floor hatch must be able to be carried out quickly and easily.

La trappe de visite selon la présente invention a pour but de satisfaire à toutes ces conditions simultanément.The inspection hatch according to this invention aims to satisfy all of these conditions simultaneously.

A cet effet, elle se compose d'un cadre dormant habillant l'ouverture et d'un cadre ouvrant bordant la dalle de fermeture, profilés tous les deux en cornière et dont les ailes montantes respectives en regard sont convergentes l'une vers l'autre.For this purpose, it consists of a framework sleeping frame opening and opening frame bordering the closing slab, both profiles in angle iron and whose respective rising wings in look are converging towards each other.

Le caractère convergent des bords latéraux de ces deux cadres permet d'admettre entre eux un joint périmètrique de section trapézoïdale garantissant avec le joint plat inférieur une bonne étanchéité aux liquides et aux gaz, mais aussi aux saletés et matières de toute sorte.The converging character of the lateral edges of these two frames allow to admit a joint between them perimeter of trapezoidal section guaranteeing with the lower flat seal a good seal against liquids and gases, but also dirt and materials of any kind.

Le joint périmètrique à section trapézoïdale est suffisamment mince vers le haut pour ne représenter qu'une faible rupture d'esthétique.The trapezoidal section perimeter seal is thin enough at the top not to represent that a slight aesthetic break.

Les deux cadres sont immobilisés l'un par rapport à l'autre soit par des moyens d'assemblage à vis soit par des dispositifs de verrouillage chacun à poignée rabattable constituant également un moyen de levage pour la dalle ou la fraction de paroi emprisonnée dans le cadre ouvrant.The two executives are immobilized one by relation to each other either by means of assembly to screw either by locking devices each to folding handle also constituting a means of lifting for slab or fraction of wall imprisoned in the opening frame.

La trappe selon l'invention ne présente ni fixation ni éléments d'extraction sur sa face supérieure constituée par un plan uniforme de carrelage.The hatch according to the invention has neither fixing or extraction elements on its face superior formed by a uniform plane of floor tile.

D'autres caractéristiques et avantages de l'invention apparaítront dans la description qui suit, donnée à titre d'exemple et accompagnée des dessins dans lesquels :

La trappe de visite selon l'invention se compose d'un cadre fixe ou dormant 1 en forme de cornière dont les dimensions lui permettent de venir se caler sur un épaulement 2 de feuillure à deux plans 3 et 4 d'une ouverture 5 dans le sol d'une pièce ou d'un local par exemple carrelé ou d'une paroi quelconque.The inspection hatch according to the invention is consists of a fixed or sleeping frame 1 in the form of angle whose dimensions allow it to come wedge on a shoulder 2 of rabbet in two planes 3 and 4 of an opening 5 in the ground of a room or a local for example tiled or any wall.

Ce cadre fixe 1 est formé de plusieurs tronçons solidarisés d'équerre présentant une aile inférieure 6 sur la face supérieure de laquelle repose sur un joint inférieur plat 7 d'étanchéité inférieure, et une aile latérale montante 8 légèrement rentrante, c'est-à-dire définissant avec l'aile inférieure 6 un angle inférieur à 90°.This fixed frame 1 is formed of several integral sections with a wing lower 6 on the upper face of which rests on a flat lower seal 7 lower seal, and an ascending lateral wing 8 slightly re-entrant, that is to say defining with the lower wing 6 a angle less than 90 °.

Dans le cas d'une trappe de sol, le cadre fixe 1 reçoit une dalle de fermeture 9 massive et lourde formée d'un bloc parallélépipèdique de béton 10 en général armé recouvert du même carrelage 11 que le sol et coulé dans un moule constitué par un cadre ouvrant 12 formé d'une part par des éléments profilés en cornière à aile inférieure 13 et à aile latérale montante 14, définissant entre elles un angle sortant, c'est-à-dire supérieur à 90°, et formé d'autre part par une plaque de fond 15 éventuellement renforcée en cas de nécessité par des profilés transversaux ou longitudinaux. Le cadre ouvrant 12 et sa plaque de fond 15 constituent un réceptacle 16 occupé par un treillis métallique 17 d'armature dans lequel est coulée la masse de béton 10.In the case of a floor hatch, the frame fixed 1 receives a massive closing slab 9 and heavy formed of a rectangular block of concrete 10 generally reinforced covered with the same tile 11 as the ground and poured into a mold consisting of a frame opening 12 formed on the one hand by profiled elements angle iron with lower wing 13 and side wing rising 14, defining between them an outgoing angle, that is to say greater than 90 °, and formed on the other hand by a bottom plate 15 possibly reinforced in case of necessity by transverse profiles or longitudinal. The opening frame 12 and its bottom plate 15 constitute a receptacle 16 occupied by a trellis metallic reinforcement 17 into which the concrete mass 10.

Afin d'assurer une meilleure solidité, les armatures c'est-à-dire les tiges du treillis 17 sont affaissées localement dans un emplacement intérieur central 18 pour constituer une zone centrale rapprochée du fond 15.In order to ensure better solidity, the reinforcements that is to say the trellis rods 17 are collapsed locally in an indoor location central 18 to form a close central zone from the bottom 15.

Afin d'améliorer la tenue du bloc de béton 10 dans le réceptacle 16, on prévoit de fixer ou de solidariser à une hauteur adaptée sur la face intérieure de l'aile latérale montante 14 une cornière périmètrique d'ancrage 19 dont l'aile latérale est en position saillante latérale oblique descendante vers l'espace intérieur central 18 du cadre ouvrant 12.To improve the strength of the concrete block 10 in the receptacle 16, provision is made for fixing or secure at a suitable height on the face interior of the rising side wing 14 an angle iron perimeter of anchor 19 whose lateral wing is in lateral oblique projecting position descending towards the central interior space 18 of the opening frame 12.

La surface supérieure du bloc de béton 10 s'arrête à un niveau tel que le plan du carrelage 11 assurant son revêtement se trouve dans le plan de sol du carrelage avoisinant après la pose.The upper surface of the concrete block 10 stops at a level such as the plane of the tiling 11 ensuring its coating is in the ground plane neighboring tiles after installation.

Les ailes obliques montantes 8 et 14 des deux cadres convergeant l'une vers l'autre délimitent un espace intermédiaire 20 de section trapézoïdale obturé au niveau de sa fente en partie supérieure par un joint périmétrique 21 ajusté à la fente de section trapézoïdale, rectangulaire ou carrée .The oblique rising wings 8 and 14 of the two frames converging towards each other define a intermediate space 20 of closed trapezoidal section at its slot in the upper part by a seal perimeter 21 adjusted to the section slot trapezoidal, rectangular or square.

Cette conformation trapézoïdale de l'espace intermédiaire 20 permet d'obtenir un joint 21 mince et un élargissement de l'espace en partie inférieure.This trapezoidal conformation of space intermediate 20 makes it possible to obtain a thin joint 21 and an enlargement of the space in the lower part.

Ce joint périmétrique 21 présente une face supérieure de faible largeur. Il est réalisé dans toute matière souple appropriée résistant aux agressions diverses mécaniques et chimiques rencontrées dans son milieu d'utilisation.This perimeter seal 21 has a face upper of small width. It is carried out in all suitable flexible material resistant to attack various mechanical and chemical encountered in its environment of use.

Pour améliorer le maintien du joint périmétrique 21 et l'étanchéité qu'il procure, les faces latérales de ce joint périmétrique peuvent présenter des structures en relief comme par exemple sous la forme de stries ou d'arêtes longitudinales ou de bourrelets longitudinaux (non représentés).To improve joint retention perimeter 21 and the tightness it provides, the side faces of this perimeter seal can present structures in relief such as for example in the form of ridges or longitudinal edges or longitudinal beads (not shown).

La trappe de visite selon l'invention présente selon la variante de la figure 4 un dispositif d'assemblage en quatre endroits associés ou non à un moyen d'extraction.The inspection hatch according to the invention according to the variant of FIG. 4, a device of assembly in four places associated or not with a means of extraction.

Selon une autre variante représentée sur les figures 2 et 3, les deux fonctions sont réunies sur un même moyen qui assure en même temps la fonction de levage. Cette autre variante est préférée en raison de la simplicité des moyens et de leur double fonction.According to another variant represented on the Figures 2 and 3, the two functions are combined on a same means which at the same time ensures the function of lifting. This other variant is preferred because of the simplicity of the means and their dual function.

La variante représentée sur la vue en coupe de la figure 4 comporte à chaque endroit spécifique d'une part un moyen d'assemblage et d'autre part un moyen d'extraction, utilisant soit l'élément d'assemblage, vis ou autre, comme prise d'extraction soit un autre moyen.The variant shown in the sectional view of figure 4 features at each specific location on the one hand a means of assembly and on the other hand a means of extraction, using either the element assembly, screw or other, as extraction socket another way.

Le moyen d'assemblage consiste en une pluralité de vis 22 et de pièces-écrou 23 disposées chacune l'une en face de l'autre.The assembly means consists of a plurality of screws 22 and nut parts 23 arranged each one facing the other.

Pour ce faire, le cadre dormant 1 présente par exemple aux trois quarts de la longueur de chaque traverse un fer plat 24 solidarisé sur chant à son aile latérale montante 8. Chaque fer plat 24 comporte un perçage 25 traversant fileté recevant une vis d'assemblage 22 et joue ainsi le rôle de pièce-écrou 23.To do this, the frame 1 has for example three-quarters of the length of each crosses a flat iron 24 secured on edge to its wing rising side 8. Each flat iron 24 has a 25 threaded through hole receiving a screw assembly 22 and thus plays the role of part-nut 23.

Cette vis d'assemblage 22 est portée par un support 26 solidarisé à la face extérieure de l'aile latérale 14 du cadre ouvrant 12. Le support 26 comporte un perçage 27 fileté ou non pour le passage de la vis 22.This assembly screw 22 is carried by a support 26 secured to the outer face of the wing side 14 of the opening frame 12. The support 26 comprises a hole 27 threaded or not for the passage of the screw 22.

L'assemblage s'effectue en quatre points régulièrement répartis sur le périmètre du cadre par l'intermédiaire de vis.Assembly takes place at four points regularly distributed around the perimeter of the framework by through screws.

En ce qui concerne l'extraction, cette fonction est assurée par un moyen différent mais complémentaire.Regarding extraction, this function is provided by a different means but complementary.

En effet, l'extraction est réalisée par l'intermédiaire de plusieurs vis-outils spéciales venant se visser chacune dans un perçage fileté du support correspondant solidaire du cadre ouvrant. Ce perçage fileté peut par exemple être le perçage 27 du support 26, réutilisé pour l'extraction après avoir retiré la vis 22. Il peut évidemment s'agir d'un perçage différent sur une pièce-écrou solidaire du cadre ouvrant.Indeed, the extraction is carried out by through several special screw-tools each screwing into a threaded hole in the corresponding support secured to the opening frame. This threaded hole can for example be hole 27 of the support 26, reused for extraction after having removed screw 22. It can obviously be a different drilling on a nut-piece integral with the opening frame.

Ces vis-outils sont par exemple conformées en extrémité selon un crochet ou toute autre forme technique spéciale pour venir s'adapter à un moyen ou engin de levage d'ensemble par l'intermédiaire de lignes ou de tout autre moyen de liaison adapté à un organe moteur.These screw tools are for example shaped as hook end or other shape special technique to adapt to a medium or overall lifting device through lines or any other means of connection suitable for a motor organ.

Dans cette variante, la fonction de levage peut être réalisée séparément par l'intermédiaire d'une fente longitudinale 28 formée dans un rebord 29 local ou continu existant dans l'espace intermédiaire ou sous la forme d'une structure réceptrice solidarisée à l'aile montante 14 du cadre ouvrant et d'un outil de levage 30 à extrémité de forme appropriée par exemple en crochet ou en T venant coopérer avec cette fente ou cette structure réceptrice en vue de constituer un point d'appui pour le levage, par exemple manuel.In this variant, the lifting function can be done separately through a longitudinal slot 28 formed in a local flange 29 or continuous existing in the intermediate space or under the shape of a receiving structure secured to the rising wing 14 of the opening frame and of a lifting 30 at end of suitable shape for example hook or T coming to cooperate with this slot or this receiving structure in order to constitute a support point for lifting, for example manual.

On décrira maintenant en détail la variante préférée à poignées escamotables.We will now describe in detail the variant preferred with retractable handles.

Selon cette variante, l'assemblage des deux cadres 1 et 12 s'effectue par l'intermédiaire d'un verrou venant immobiliser les deux cadres entre eux.According to this variant, the assembly of the two frames 1 and 12 is carried out via a lock coming to immobilize the two frames between them.

Plus particulièrement, en référence aux figures 1, 2 et 3 illustrant une forme de réalisation de cette variante, la trappe comporte quatre verrous placés chacun au niveau de chaque angle. Ces verrous comprennent chacun une poignée plate 31 pivotant entre une position relevée de verrouillage-extraction et une position rabattue de verrouillage.More specifically, with reference to Figures 1, 2 and 3 illustrating an embodiment of this variant, the hatch has four latches each placed at each corner. These locks each include a flat handle 31 pivoting between a raised locking-extracting position and a folded locking position.

A cet effet, la poignée plate 31 est découpée dans un fer plat et montée pivotante autour d'un axe transversal 32 au niveau de son extrémité avant, conformée selon une rampe descendante 33 suivie d'une plage longitudinale 34. L'extrémité avant présente dans sa demi-partie inférieure un nez 35 constitué par un pan frontal 36 suivi d'une rampe oblique de raccordement 37 avec le chant inférieur longitudinal 38 parallèle au chant supérieur longitudinal 39 s'étendant sur toute la longueur de la poignée.For this purpose, the flat handle 31 is cut out in a flat iron and pivotally mounted around an axis transverse 32 at its front end, shaped according to a downward ramp 33 followed by a longitudinal range 34. The front end present in its lower half-portion a nose 35 consisting of a front panel 36 followed by an oblique ramp of connection 37 with the longitudinal lower edge 38 parallel to the longitudinal upper edge 39 extending along the entire length of the handle.

La conformation de l'extrémité avant permet, lorsque la poignée est rabattue, de verrouiller les deux cadres 1 et 12 entre eux.The conformation of the front end allows, when the handle is folded down, lock the two frames 1 and 12 between them.

Le corps de la poignée présente une zone de préhension 40 formée par une rampe inclinée 41 suivie d'une extrémité 42 en arrondi concave ou en crochet.The handle body has an area of grip 40 formed by an inclined ramp 41 followed of an end 42 in concave rounding or in hook.

Cette zone de préhension se poursuit par une extrémité arrière 43 formée d'une extension transversale 44 se poursuivant longitudinalement vers l'arrière dans sa partie supérieure pour former une queue 45.This gripping area continues with a rear end 43 formed of an extension transverse 44 continuing longitudinally towards the back in its upper part to form a tail 45.

En partie inférieure, l'extrémité arrière 43 présente une découpe 46 en arrondi concave coopérant avec un moyen d'encliquetage 47 lorsque la poignée est rabattue en position de verrouillage. Ce moyen a pour but de maintenir la poignée dans cette position rabattue. Il procure une garantie suffisante de non déblocage même dans le cas de mouvements brusques de la dalle lors du passage de charges sur celle-ci.In the lower part, the rear end 43 has a concave concave rounded cutout 46 with a latching means 47 when the handle is folded back in the locked position. This means purpose of holding the handle in this position folded down. It provides an adequate guarantee of no release even in the case of sudden movements of the slab when passing loads on it.

La poignée pivote dans un plan parallèle à la face extérieure de l'aile supérieure du cadre ouvrant. Elle se trouve proche et parallèle à cette aile. Son épaisseur lui permet d'occuper une grande partie du volume intérieur de l'espace entre les deux ailes en regard des deux cadres.The handle pivots in a plane parallel to the outer face of the upper wing of the opening frame. It is close and parallel to this wing. His thickness allows it to occupy a large part of the interior volume of the space between the two wings in look of the two frames.

L'extrémité arrière 43 de la poignée vient se caler dans l'extrémité d'un fer plat 48 de renforcement et d'appui monté solidaire de la face extérieure de l'aile du cadre ouvrant et dont le chant supérieur 49 définit un épaulement sur lequel vient reposer le joint périmétrique 21.The rear end 43 of the handle comes wedge in the end of a reinforcing flat iron 48 and support mounted integral with the outer face of the wing of the opening frame and whose upper edge 49 defines a shoulder on which the seal rests perimeter 21.

Le chant supérieur 39 de la poignée, lorsqu'elle se trouve rabattue, prolonge ce chant supérieur 49 et donc la surface d'appui du joint. L'extrémité de chaque fer plat 48 au niveau de la poignée 31 est conformée selon un décrochement 50 à rampe supérieure par exemple oblique dans lequel vient se caler la queue 45 de chaque poignée 31. L'extrémité se poursuit vers le bas par une face frontale 51 sur laquelle est monté un élément élastique 52 adapté à la découpe 46 de la poignée formant ensemble un moyen d'immobilisation par encliquetage.The upper edge 39 of the handle, when it is folded down, prolong this song upper 49 and therefore the bearing surface of the seal. The end of each flat iron 48 at the level of the handle 31 is shaped according to a step 50 to upper ramp for example oblique in which comes wedge the tail 45 of each handle 31. The end continues downwards by a front face 51 on which is mounted an elastic element 52 adapted to the cutout 46 of the handle together forming a means locking system.

Bien entendu l'immobilisation de la poignée peut s'effectuer par bien d'autres moyens équivalents à celui décrit ci-dessus ou constituant des variations simples ou évidentes.Of course the immobilization of the handle can be done by many other means equivalent to the one described above or constituting variations simple or obvious.

Il existe un espace 53 entre l'extrémité de la queue 45 et la pente du décrochement 50 pour l'introduction d'une tige ou d'une lame et plus particulièrement d'un outil ou instrument adapté en vue d'extraire la queue 45 de la poignée 31 dans un premier mouvement de pivotement.There is a space 53 between the end of the tail 45 and the slope of the offset 50 for the introduction of a rod or blade and more particularly of a tool or instrument suitable for extract the tail 45 from the handle 31 in a first pivoting movement.

L'extrémité avant de la poignée traverse l'aile montante 8 du cadre dormant 1 par une fente transversale 54 prévue au droit du nez 35 de la poignée.The front end of the handle crosses the rising wing 8 of the sleeping frame 1 through a slot transverse 54 provided to the right of the nose 35 of the handle.

Ces fentes 54 sont de dimensions et de position telles que l'extrémité du nez 35 de la poignée 31 vient s'immobiliser dans la fente transversale du cadre dormant proche de l'arête d'angle 55 visible sur la figure 1. Le blocage de verrouillage est assuré par la butée du bord supérieur du nez 35 contre le bord supérieur 56 de la fente 54 du cadre fixe ou dormant 1.These slots 54 are of dimensions and position such as the end of the nose 35 of the handle 31 comes to rest in the transverse slot of the sleeping frame close to the corner edge 55 visible on Figure 1. The locking lock is provided by the stop of the upper edge of the nose 35 against the edge upper 56 of the slot 54 of the fixed or standing frame 1.

L'ouverture de la trappe pour des visites ou des interventions techniques s'effectue de la façon suivante.Opening the hatch for visits or technical interventions are carried out in the next.

Après extraction du joint périmétrique 21 à l'aide d'un outil ou d'un instrument plat permettant de le comprimer latéralement puis de l'extraire de son logement et de l'enlever, on soulève l'extrémité arrière 43 de la poignée 31 à l'aide par exemple du même outil que l'on engage dans l'espace libre 53 à l'extrémité de la queue 45. Après avoir vaincu la force d'encliquetage par un mouvement de basculement de l'outil vers le haut, l'extrémité arrière 43 de la poignée 31 se soulève. On poursuit le mouvement jusqu'à ce que l'extrémité arrière 43 soit suffisamment haute pour pouvoir la saisir à la main. Au cours de ce mouvement l'extrémité avant de la poignée 31 se dégage de la fente 54 correspondante prévue dans le cadre fixe et libère ainsi le verrouillage d'assemblage des deux cadres. Le corps de la poignée 31 est amené en position verticale dans laquelle les deux cadres sont entièrement libérés. Il suffit de lever la dalle 9 en prenant les quatre poignées 31 comme moyen de préhension soit directement à la main pour les dalles 9 d'un poids compatible avec un effort manuel, soit à l'aide d'un appareil de levage : treuil sur support ou autre ou d'un engin de levage.After extraction of the perimeter seal 21 to using a flat tool or instrument to compress it laterally then extract it from its housing and remove it we lift the end rear 43 of the handle 31 using for example the same tool that is engaged in free space 53 to the end of the tail 45. After having overcome the force latching by a tilting movement of the tool up, the rear end 43 of the handle 31 lifts. We continue the movement until the rear end 43 is high enough to be able to grab it by hand. During this movement the front end of the handle 31 is released of the corresponding slot 54 provided in the fixed frame and thus frees the assembly lock of the two frames. The body of the handle 31 is brought into position vertical in which the two frames are fully released. Just lift the slab 9 in taking the four 31 handles as a means of gripping either directly by hand for slabs 9 of a weight compatible with manual effort, i.e. using a lifting device: winch on support or other or lifting gear.

La fermeture de la trappe s'effectue dans le sens inverse et ceci sans nécessiter en principe l'emploi d'un quelconque outil.The hatch is closed in the reverse and this without in principle requiring the use of any tool.

La figure 6 montre la trappe selon l'invention dans son application en trappe de sol. On remarque sa parfaite intégration esthétique grâce à son joint périmétrique 21 à face supérieure mince dans une surface carrelée 56 du sol 57.Figure 6 shows the hatch according to the invention in its application as a floor hatch. We notices its perfect aesthetic integration thanks to its perimeter seal 21 with thin upper face in a tiled surface 56 of floor 57.
