La poignée selon l'invention se présente sous la forme d'une coquille (1) monobloc en acier ou autre matériau moulé dont la conformation est étudiée pour remplir plusieurs fonctions à savoir :
- fonction de préhension,
- support de ventouses électromagnétiques,
- boîtier pour composants et contacts électriques.
- gripping function,
- electromagnetic pad support,
- housing for electrical components and contacts.
La fonction de préhension est réalisée par l'extension latérale (2) de forme ergonomique avec une partie arrière creuse (14) facilitant la préhension.The gripping function is performed by the lateral extension (2) of ergonomic shape with a hollow rear part (14) facilitating the gripping.
Le support de ventouses est formé de deux alvéoles cylindriques (3) (4) ouvertes vers l'arrière de la coquille (1) et dimensionnées pour recevoir chacune une ventouse standard (6).The suction cup support is formed by two cylindrical cells (3) (4) open towards the rear of the shell (1) and dimensioned to each receive a standard suction cup (6).
Le fond de chaque alvéole (3) (4) comporte un trou central (7) pour la fixation de la ventouse et une réservation rectangulaire périphérique (5) pour le passage d'un conducteur électrique d'alimentation de la ventouse.The bottom of each cell (3) (4) has a central hole (7) for fixing the suction cup and a rectangular rectangular reservation (5) for the passage of an electrical conductor supplying the suction cup.
Les ventouses (6) sont montées flottantes dans la coquille et fixées chacune par un palonnier élastique (21) réglable par une vis (22) ou un écrou (au choix).The suction cups (6) are mounted floating in the shell and each fixed by an elastic lifter (21) adjustable by a screw (22) or a nut (optional).
Ce palonnier (21) permet l'auto alignement de la face d'appui des ventouses pendant la phase progressive du contact électromagnétique avec la contre-plaque.This lifting beam (21) allows the self alignment of the bearing face of the suction cups during the progressive phase of the electromagnetic contact with the counterplate.
Le palonnier élastique réglable en force et en profondeur assure le maintien de la ventouse et son réglage pour compenser les défauts d'alignement des montants de porte qui supportent la contre-plaque. De plus, le palonnier par sa conception absorbe les chocs de fermetures de portes.The elastic lifting beam, adjustable in strength and depth, maintains the suction cup and adjusts it to compensate for misalignments in the door jambs that support the counterplate. In addition, the lifter by its design absorbs the shocks of door closings.
Le blocage en rotation de la ventouse, pendant son réglage et son fonctionnement, est garanti par un ergot venant directement du corps de la poignée.The locking in rotation of the suction cup, during its adjustment and its operation, is guaranteed by a lug coming directly from the body of the handle.
Sur l'huisserie de la porte, et en regard des ventouses, on prévoit de façon classique deux contre-plaques (8) pour le verrouillage électromagnétique.On the door frame, and facing the suction cups, two counter plates (8) are conventionally provided for electromagnetic locking.
Le boîtier (9) pour les composants est un logement en deux parties, ouvert vers l'avant de la coquille et comportant une partie circulaire avant (10) adjacente aux fonds des alvéoles et de profondeur réduite, prolongée vers l'arrière par une partie (11) plus profonde, disposée sur le côté des alvéoles (3) (4) vers l'extension (2).The housing (9) for the components is a housing in two parts, open towards the front of the shell and comprising a circular front part (10) adjacent to the bottom of the cells and of reduced depth, extended towards the rear by a part (11) deeper, arranged on the side of the cells (3) (4) towards the extension (2).
La partie arrière (11) du boîtier (9) est conformée et dimensionnée autour des trois trous de fixation (12) de la poignée sur la porte ou le ventail et de façon à libérer au maximum la partie arrière creuse (14) de l'extension (2).The rear part (11) of the housing (9) is shaped and dimensioned around the three fixing holes (12) of the handle on the door or the fan and so as to free the hollow rear part (14) as much as possible. extension (2).
Les réservations (5) des fonds d'alvéoles débouchent non limitativement, à la jonction des deux parties (10) (11) du boîtier.The reservations (5) of the bottom of the cells open out without limitation, at the junction of the two parts (10) (11) of the housing.
La partie avant (10) du boîtier porte deux contacts électriques (13) coopérant avec l'huisserie fixe de la porte, disposés entre les deux ventouses et sur le plan de symétrie AX de la poignée.The front part (10) of the housing carries two electrical contacts (13) cooperating with the fixed frame of the door, arranged between the two suction cups and on the plane of symmetry AX of the handle.
Deux contacts électriques polaires (13), isolés du corps par des bagues en matériaux isolants, assurent en plus de la liaison électrique l'éloignement de la poignée pour compenser l'effet de rémanence magnétique des ventouses, quand l'alimentation est coupée, pour faciliter l'ouverture de la porte par un enfant. Ces mêmes contacts garantissent, par la pression des ressorts, la qualité du contact électrique avec la contre-plaque.Two polar electrical contacts (13), isolated from the body by rings of insulating materials, ensure in addition to the electrical connection the distance from the handle to compensate for the effect of magnetic remanence of the suction cups, when the power is off, to facilitate the opening of the door by a child. These same contacts guarantee, by the pressure of the springs, the quality of the electrical contact with the counterplate.
Ils assurent aussi la fermeture progressive de la porte (poignée) pendant la phase d'approche magnétique (la porte ne claque pas).They also ensure the progressive closing of the door (handle) during the magnetic approach phase (the door does not slam).
La partie avant (10) du boîtier comporte une ouverture (15). De préférence, pour l'esthétique de l'ensemble cette ouverture est circulaire et décentrée et elle est dimensionnée de façon à permettre un accès facile à tous les éléments à fixer dans les trous (7) (12) (13). Cette ouverture (15) est obturée par un cache (17) (voir figure 4) plaqué contre un rebord périphérique (16) de l'ouverture (15) et maintenu par tout moyen de fixation approprié.The front part (10) of the housing has an opening (15). Preferably, for the aesthetics of the assembly, this opening is circular and off-center and it is dimensioned so as to allow easy access to all the elements to be fixed in the holes (7) (12) (13). This opening (15) is closed by a cover (17) (see FIG. 4) pressed against a peripheral rim (16) of the opening (15) and held by any suitable fixing means.
A cet effet, on a prévu au centre de l'ouverture (15), un picot conique creux (20) venu de moulage avec la partie arrière du boîtier dont l'extrémité plate porte un écrou à sertir (18) affleurant l'ouverture (15) (voir figure 4) et dont la vis de fixation (19) est accessible par l'arrière du boîtier pour son montage et son démontage.For this purpose, there is provided in the center of the opening (15), a hollow conical pin (20) molded with the rear part of the housing, the flat end of which carries a crimp nut (18) flush with the opening. (15) (see Figure 4) and whose fixing screw (19) is accessible from the rear of the housing for mounting and dismounting.
La fixation du cache par rotation de celui-ci autour du picot conique (20), est assuré par une vis ou un écrou. De préférence le cache est métallique et son entraînement en rotation, pour le vissage, est assuré par un outil magnétique qui reste à l'opérateur. Cette technique assure la non violabilité de la poignée.The fixing of the cover by rotation of the latter around the conical pin (20) is ensured by a screw or a nut. Preferably the cover is metallic and its rotation drive, for screwing, is ensured by a magnetic tool which remains with the operator. This technique ensures the non-violability of the handle.
La poignée décrite ci-dessus est un mode de réalisation préféré de l'invention qui présente un plan de symétrie et deux ventouses de façon à répartir et équilibrer les efforts.The handle described above is a preferred embodiment of the invention which has a plane of symmetry and two suction cups so as to distribute and balance the forces.
Bien entendu le nombre des ventouses des réservations des points de fixations, ainsi que la forme du boîtier (9) de composants et la forme de l'extention (2) peuvent varier en fonction de l'esthétique recherchée, et/ou du circuit électrique, et/ou de la force de vérouillage.Of course the number of suction cups for the reservations of the fixing points, as well as the shape of the housing (9) of components and the shape of the extension (2) can vary depending on the desired aesthetics, and / or the electrical circuit. , and / or the locking force.
