Description

La présente invention concerne un système d'équilibrage de trappe pivotante. L'invention est notamment applicable à l'équilibrage d'une trappe d'accès à une machinerie d'ascenseur.The present invention relates to a pivoting hatch balancing system. The invention is particularly applicable to the balancing of an access hatch to an elevator machinery.

Il est connu d'utiliser des systèmes d'équilibrage de trappe d'accès par contre-balancement. Les trappes étant souvent renforcées pour supporter le poids d'une personne se déplaçant à leur surface lorsqu'elles sont en position rabattue, ces systèmes d'équilibrage facilitent leur ouverture.It is known to use counterbalance access hatch balancing systems. The hatches are often reinforced to support the weight of a person moving on their surface when they are in the folded position, these balancing systems facilitate their opening.

On évite ainsi qu'une fausse manoeuvre de l'opérateur entraîne un rabattement soudain de la trappe sur celui-ci et qu'il puisse être blessé.This avoids a false maneuver of the operator causes a sudden folding of the door on it and he can be injured.

La Figure 1 montre schématiquement un tel système d'équilibrage de trappe d'accès à une machinerie d'ascenseur de l'art antérieur. Ce système comprend un lest 1 relié par un câble 2 à une extrémité de la trappe 3. Le câble passe par deux poulies 4, 5 permettant au lest 1 de se déplacer dans un plan vertical lors d'une poussée de la trappe 3 par l'opérateur. Une crosse de maintien mural 6 et une crosse de rétablissement fixé au sol 7 peuvent permettre à l'opérateur de prendre appui en sortie de la trappe 3.The Figure 1 schematically shows such a door access balancing system access to a lift machine of the prior art. This system comprises a ballast 1 connected by a cable 2 to one end of the hatch 3. The cable passes through two pulleys 4, 5 allowing the ballast 1 to move in a vertical plane during a thrust of the hatch 3 by the 'operator. A wall-mounted buttstock 6 and a recovery hook attached to the ground 7 may allow the operator to support the output of the hatch 3.

A part le lest 1 qui est mobile, l'ensemble de ces éléments sont fixés indépendamment les uns des autres sur des maçonneries. L'opérateur doit donc dans un premier temps trouver un espace suffisant pour positionner ces éléments. En effet, le déplacement du lest 1 dans un plan vertical doit être exempt de tout obstacle de nature à empêcher un fonctionnement satisfaisant du système d'équilibrage.Apart from the ballast 1 which is mobile, all of these elements are fixed independently of each other on masonry. The operator must first find sufficient space to position these elements. Indeed, the displacement of the ballast 1 in a vertical plane must be free of all obstacle to prevent satisfactory operation of the balancing system.

Ensuite, l'opérateur doit fixer en position ces éléments en s'assurant du bon alignement de ceux-ci afin que le câble 2 puisse se déplacer librement lors de l'actionnement de la trappe 3. Outre des erreurs éventuelles d'alignement diminuant les performances du système d'équilibrage, les opérations de pose d'un tel système d'équilibrage sont longues et coûteuses.Then, the operator must fix in position these elements ensuring proper alignment so that the cable 2 can move freely when actuating the hatch 3. In addition to possible alignment errors decreasing the performance of the balancing system, the installation operations of such a balancing system are long and expensive.

Enfin, ces systèmes d'équilibrage sont encombrants. Le lest 1 étant souvent en retrait par rapport à la trappe d'accès 3, le câble 2 reliant cette trappe au lest 1 se trouve dans le passage de travail de l'opérateur à hauteur d'homme, ce qui peut rendre ses déplacements difficiles et son travail pénible. Ce câble 2 peut de plus provoquer une chute de l'opérateur.Finally, these balancing systems are bulky. The ballast 1 is often set back relative to the access hatch 3, the cable 2 connecting the hatch to the ballast 1 is in the working passage of the operator at man's height, which can make his movements difficult. and his painful work. This cable 2 may further cause a fall of the operator.

Il existe donc un besoin pressant pour un système d'équilibrage qui soit facile à installer et compact afin de ne pas gêner l'opérateur dans ses activités.There is therefore a pressing need for a balancing system that is easy to install and compact so as not to hinder the operator in its activities.

L'objectif de la présente invention est donc de proposer un système d'équilibrage pour trappe pivotante, simple dans sa conception et dans son mode opératoire, économique et dont l'installation est facile.The object of the present invention is therefore to provide a balancing system for pivoting hatch, simple in its design and in its operating mode, economical and easy to install.

A cet effet, l'invention concerne un système d'équilibrage de trappe pivotante, comprenant un organe de renvoi et un contrepoids susceptible de se déplacer le long d'un axe de déplacement, le contrepoids étant relié par un élément de liaison à la trappe, l'élément de liaison passant par l'organe de renvoi. Selon l'invention,

  • l'organe de renvoi est fixé sur un organe support comportant l'axe de déplacement,
  • le système comprend un élément de retenue de la trappe monté sur l'organe support,
  • l'organe support comporte des moyens de fixation au sol et/ou à une paroi verticale.

According to the invention,
  • the return member is fixed on a support member comprising the axis of displacement,
  • the system comprises a retaining element of the hatch mounted on the support member,
  • the support member comprises ground fixing means and / or a vertical wall.

La trappe peut être indifféremment à un ou deux vantaux. Ce système d'équilibrage est particulièrement compact et peut être fixé au sol à proximité de la trappe pivotante.The hatch can be indifferently to one or two leaves. This balancing system is particularly compact and can be fixed to the ground near the pivoting hatch.

Dans différents modes de réalisation particuliers de ce système d'équilibrage, chacun ayant ses avantages particuliers et susceptibles de nombreuses combinaisons techniques possibles:

  • l'organe support comporte une partie verticale creuse logeant le contrepoids, le contrepoids étant destiné à se déplacer dans cette partie creuse le long de l'axe de déplacement,
    Le contrepoids étant logé dans cette partie creuse, on s'assure ainsi avantageusement qu'aucun obstacle ne vient empêcher le déplacement de celui-ci. Cette partie creuse peut être un tube creux de section cylindrique, carrée, rectangulaire ou autre.
  • l'organe support comprend un bras coudé pour recevoir l'organe de renvoi, ce bras étant monté, de manière amovible ou non, à l'extrémité de la partie creuse et permettant le passage de l'élément de liaison,
    Lorsqu'il est amovible, ce bras permet son démontage pour accéder au contrepoids de manière particulièrement simple.
  • le système comporte des moyens d'ajustement de la hauteur de l'organe de renvoi par rapport à la partie verticale creuse,

    Ce contrepoids peut comporter une ou plusieurs masselottes amovibles de sorte qu'il est possible d'adapter le contrepoids en fonction de l'aide nécessaire à apporter à la poussée de la trappe ou lors du remplacement de la trappe par une trappe pivotante de masse différente. Ce rail est typiquement une barre comportant une surface supérieure apte au déplacement du chariot. L'axe longitudinal de cette barre définit l'axe de déplacement du contrepoids. Cette barre étant inclinée par rapport au sol, une première extrémité est solidarisée au sol par des moyens de fixation tels qu'une plaque de fixation et des vis tandis que sa deuxième extrémité est maintenue en élévation, en étant soutenue, par une tige métallique ancrée au sol par des moyens de fixation identiques aux précédents. L'organe de renvoi est fixé à cette deuxième extrémité de sorte que l'élément de liaison du type câble puisse se déplacer librement le long de l'axe de déplacement en étant entraîné par le chariot mobile.
  • le rail comprend une butée de fin de course afin d'empêcher une désolidarisation du chariot et du rail,
    Cette butée de fin de course permet d'éviter que le chariot ne puisse sortir du rail en cas de rupture accidentelle de l'élément de liaison reliant le chariot à la trappe.
  • l'élément de retenue de la trappe est monté de manière coulissante le long d'un élément de guidage,
  • l'élément de retenue de la trappe comprend un bras comportant un crochet à son extrémité, ce bras étant ajustable en longueur pour s'adapter à l'épaisseur de la trappe,

  • le système d'équilibrage comporte au moins une crosse de rétablissement montée sur ledit organe support.
In different particular embodiments of this balancing system, each having its particular advantages and capable of many possible technical combinations:
  • the support member comprises a hollow vertical part housing the counterweight, the counterweight being intended to move in this hollow part along the axis of displacement,
    The counterweight being housed in this hollow part, it is thus ensured that no obstacle prevents the movement thereof. This hollow part may be a hollow tube of cylindrical, square, rectangular or other section.
  • the support member comprises an angled arm for receiving the return member, this arm being mounted, removably or not, at the end of the hollow portion and allowing the passage of the connecting element,
    When removable, this arm allows disassembly to access the counterweight in a particularly simple manner.
  • the system comprises means for adjusting the height of the return member relative to the hollow vertical portion,
  • the support member is an inclined guide rail defining an axis of displacement and on which is mounted a movable carriage receiving the counterweight,
    This counterweight may comprise one or more removable weights so that it is possible to adapt the counterweight as a function of the assistance needed to provide the thrust of the hatch or when replacing the hatch by a pivoting flap of different mass . This rail is typically a bar having an upper surface capable of moving the carriage. The longitudinal axis of this bar defines the axis of displacement of the counterweight. This bar being inclined relative to the ground, a first end is secured to the ground by fastening means such as a fixing plate and screws while its second end is maintained in elevation, being supported, by a metal rod anchored on the ground by fixing means identical to the previous ones. The return member is attached to this second end so that the cable-type connecting member can move freely along the axis of movement being driven by the movable carriage.
  • the rail comprises an end stop to prevent separation of the carriage and the rail,

Les Figures 2 et 3 montrent un système d'équilibrage d'une trappe pivotante selon un mode de réalisation particulier de l'invention. Ce système comprend un organe support comportant d'une part une partie creuse verticale 10 telle qu'un tuyau creux de section sensiblement carrée et à l'extrémité supérieure de cette partie verticale, un bras coudé 11 ayant la forme d'une simple plaque plié à angle droit. Le bras coudé 11 est relié de manière ajustable en hauteur par rapport à la partie creuse 10.The Figures 2 and 3 show a balancing system of a pivoting flap according to a particular embodiment of the invention. This system comprises a support member comprising on the one hand a vertical hollow portion 10 such as a hollow pipe of substantially square section and at the upper end of this vertical portion, an angled arm 11 having the shape of a simple folded plate at right angles. The bent arm 11 is connected in an adjustable manner in height relative to the hollow portion 10.

La partie creuse 10 comprend un axe de déplacement vertical 12 le long duquel peut se déplacer un contrepoids 13 logé dans cette partie. Le contrepoids est relié à une trappe (non représentée) par l'intermédiaire d'un câble 14. Ce câble 14 passe par l'intermédiaire d'une poulie de renvoi 15 fixée de manière mobile en rotation sous la surface du bras coudé 11.The hollow portion 10 comprises a vertical axis of movement 12 along which a counterweight 13 housed in this part can move. The counterweight is connected to a hatch (not shown) by means of a cable 14. This cable 14 passes through a return pulley 15 rotatably fixed under the surface of the bent arm 11.

Le contrepoids 13 est constitué d'une pluralité de masselottes reliées entre elles de sorte qu'il est possible de faire varier la masse de ce contrepoids 13.The counterweight 13 consists of a plurality of weights connected together so that it is possible to vary the mass of the counterweight 13.

L'organe support est métallique. Il peut être réalisé à titre d'exemple en acier ou acier inoxydable. Le contrepoids 13 peut être métallique, en bois, en béton ou en plastique dur.The support member is metallic. It can be made by way of example in steel or stainless steel. The counterweight 13 may be metal, wood, concrete or hard plastic.

L'organe support comporte également des moyens de fixation au sol et/ou à une paroi verticale. Ces moyens de fixation à une paroi verticale comportent ici des oreilles 16 ayant chacune un orifice 17 pour permettre le passage au travers de la tige d'un élément de fixation du type vis et boulon.The support member also comprises ground fixing means and / or a vertical wall. These vertical wall attachment means here comprise lugs 16 each having an orifice 17 to allow the passage through the rod of a fixing element of the screw and bolt type.

Les moyens de fixation au sol comportent une plaque 18 solidaire de la partie creuse 10 et comprenant des orifices 19 pour permettre le passage au travers de chacun de ces orifices 19 de la tige d'un élément de fixation du type vis et boulon.The ground fastening means comprise a plate 18 secured to the hollow portion 10 and including orifices 19 to allow the passage through each of these orifices 19 of the rod of a fastener of the screw and bolt type.

Le système comprend aussi un élément de retenue 20 de ladite trappe monté sur l'organe support au niveau de sa partie creuse 10. Cet élément de retenue 20 de la trappe est monté de préférence de manière coulissante le long d'un élément de guidage 21 de façon à s'adapter aux dimensions de la trappe. Cet élément de guidage 21 peut être un rail de guidage formé par deux parties longitudinales présentant chacune une section ayant une forme de L. Ces parties longitudinales sont, par exemple, fixées par soudure sur la surface externe de la partie creuse 10.The system also comprises a retaining element 20 of said trapdoor mounted on the support member at its hollow portion 10. This retaining element 20 of the trapdoor is preferably slidably mounted along a guide element 21. to adapt to the dimensions of the hatch. This guide element 21 may be a guide rail formed by two longitudinal portions each having a section having an L-shape. These longitudinal parts are, for example, fixed by welding on the outer surface of the hollow portion 10.

L'élément de retenue 20 de la trappe comprend ici un bras comportant un crochet 22 à son extrémité, ledit bras étant ajustable en longueur pour s'adapter à l'épaisseur de la trappe. Les parties longitudinales à section en forme de L sont espacées pour former une rainure centrale permettant le passage du bras de l'élément de retenue 20.The retaining element 20 of the hatch here comprises an arm having a hook 22 at its end, said arm being adjustable in length to adapt to the thickness of the hatch. The longitudinal portions of L-shaped section are spaced to form a central groove allowing passage of the arm of the retaining element 20.

Cet élément de retenue 20 peut comporter également des moyens d'arrêt permettant son maintien à une position donnée le long de l'élément de guidage 21.This retaining element 20 may also include stop means for holding it at a given position along the guide element 21.

A titre purement illustratif, le bras de cet élément de retenue 20 comprenant une portion cylindrique présentant un filetage sur sa surface externe, ces moyens d'arrêt sont deux boulons montés sur cette portion cylindrique et venant de part et d'autre des parties longitudinales à section en forme de L. En serrant ces boulons, l'opérateur vient bloquer en position l'élément de retenue 20.As a purely illustrative example, the arm of this retaining element 20 comprising a cylindrical portion having a thread on its outer surface, these stop means are two bolts mounted on this cylindrical portion and coming from either side of the longitudinal parts to L-shaped section. By tightening these bolts, the operator locks the retaining element 20 in position.

Le système peut comporter deux crosses de rétablissement 23, 24 montées chacune sur un bord latéral de la partie verticale creuse 10 pour faciliter le rétablissement de l'opérateur accédant dans la machinerie après avoir levé la trappe d'accès.The system may comprise two recovery brackets 23, 24 each mounted on a lateral edge of the hollow vertical portion 10 to facilitate the recovery of the operator accessing the machinery after raising the access door.

Enfin, le système d'équilibrage comprend de préférence un élément de blocage (non représenté) pour bloquer le déplacement du contrepoids 13 le long de son axe de déplacement 12 et permettre ainsi la désolidarisation de l'extrémité du câble 14 de la trappe. Le câble 14 comporte alors une attache rapide de type manille.Finally, the balancing system preferably comprises a locking element (not shown) to block the displacement of the counterweight 13 along its axis of movement 12 and thus allow the end of the cable 14 of the hatch to be disconnected. The cable 14 then comprises a quick coupler of the shackle type.

Ainsi après avoir rabattu la trappe, le câble 14 étant sous tension et le contrepoids 13 se trouvant dans la partie supérieure de la partie creuse verticale 10, l'opérateur peut insérer une clavette au travers de deux orifices 25 réalisés en vis-à-vis sur le corps de la partie creuse verticale 10. Cette clavette étant placée sous le contrepoids 13 vient soutenir celui-ci et permettre à l'opérateur de libérer l'extrémité du câble 14 de la trappe. Une portion du câble 14 peut alors être placé dans un logement prévu à cet effet sur l'organe support. Ce mode de réalisation permet avantageusement à l'opérateur de se mouvoir sans être gêné par un câble 14 sous tension.Thus after having folded the hatch, the cable 14 being under tension and the counterweight 13 being in the upper part of the vertical hollow portion 10, the operator can insert a key through two orifices 25 made vis-à-vis on the body of the vertical hollow portion 10. This key being placed under the counterweight 13 supports the latter and allow the operator to release the end of the cable 14 of the hatch. A portion of the cable 14 can then be placed in a housing provided for this purpose on the support member. This embodiment advantageously allows the operator to move without being disturbed by a cable 14 under tension.
