Description

L'invention se rapporte au secteur technique des joints de garniture et d'étanchéité des portes de fours de cuisson.The invention relates to the technical sector of the lining and sealing joints of the doors of baking ovens.

Il est connu de réaliser des joints (1) comprenant un treillis métallique tubulaire (2) sur lequel est tissée une garniture textile (3) en matériau apte à répondre aux conditions de température environnante.It is known to produce seals (1) comprising a tubular metal mesh (2) on which is woven a textile lining (3) of material capable of meeting the conditions of surrounding temperature.

Cet ensemble (2-3) est usuellement monté ou glissé autour d'un fil métallique (F) dénommé cadre métallique créant le maintien; le fil est établi dans une configuration rectangulaire formant le cadre pour l'adaptation sur l'encadrement de porte du four de cuisson. Ces joints ont une configuration fermée, aux formes des encadrements (P1) de portes précitées, et sont agencés pour recevoir des agrafes métalliques destinées à être insérées dans les ouvertures aménagées sur la bordure périphérique de la porte.This assembly (2-3) is usually mounted or slid around a metal wire (F) called a metal frame creating the support; the wire is established in a rectangular configuration forming the frame for adaptation to the door frame of the baking oven. These seals have a closed configuration, in the forms of the frames (P1) of the aforementioned doors, and are arranged to receive metal clips intended to be inserted into the openings provided on the peripheral edge of the door.

Ces agrafes (4) ont une configuration représentée figure 1, et comprennent ainsi une plaque profilée en U (4a) ayant une capacité élastique de déformation dont les extrémités (4b) sont munies de crochets (4c) orientés en opposition et servant à la fixation de l'agrafe sur le cadre métallique (F) support du joint.These staples (4) have a configuration shown in Figure 1, and thus comprise a U-shaped plate (4a) having an elastic deformation capacity whose ends (4b) are provided with hooks (4c) oriented in opposition and used for fixing of the clip on the metal frame (F) supporting the seal.

Entre les extrémités formant crochets et la base de l'agrafe, est formé un étranglement (4d) qui vient en alignement après montage de l'agrafe avec le plan des ouvertures (5) de l'encadrement (P1).Between the ends forming hooks and the base of the clip, a constriction (4d) is formed which comes into alignment after mounting the clip with the plane of the openings (5) of the frame (P1).

En pratique, ce type d'agrafe présente des inconvénients par suite d'une tenue insuffisante sur le joint. La mise en place de l'agrafe n'est pas pratique et il y a des risques de détériorations de la garniture textile elle-même.In practice, this type of staple has drawbacks due to insufficient holding on the joint. The installation of the staple is impractical and there is a risk of damage to the textile lining itself.

Pour remédier à ces inconvénients, le demandeur a recherché et développé deux dispositifs d'agrafes de joints pour lesquels des demandes de brevets ont été présentées sous les numéros 97.14480 et 97.14479 au nom du demandeur.To remedy these drawbacks, the applicant has researched and developed two joint staple devices for which patent applications have been submitted under the numbers 97.14480 and 97.14479 in the name of the applicant.

Les configurations d'agrafes décrites dans ces deux demandes de brevets permettent de s'affranchir du cadre métallique (F) tout en permettant une stabilité de positionnement des agrafes nettement améliorée par rapport à l'art antérieur précité.The configurations of staples described in these two patent applications make it possible to dispense with the metal frame (F) while allowing positioning stability of the staples significantly improved compared to the aforementioned prior art.

Dans le cadre de ses recherches, le demandeur a développé une autre réalisation de l'agrafe autorisant la suppression du cadre métallique selon l'art antérieur.As part of his research, the applicant has developed another embodiment of the clip authorizing the removal of the metal frame according to the prior art.

Selon une première caractéristique de l'invention, le dispositif d'agrafage de joints pour fours de cuisson est caractérisé en ce qu'il comprend une pluralité d'agrafes qui sont susceptibles d'être positionnées, introduites dans au moins l'épaisseur de la garniture textile et d'un treillis métallique éventuel du joint, chaque agrafe ayant une configuration en V, avec deux branches symétriques, présentant une partie en retrait formant un rétrécissement susceptible d'être situées dans l'épaisseur de la garniture textile et du treillis métallique, ladite forme en retrait se prolongeant elle-même par deux extrémités susceptibles de se juxtaposer dans un plan horizontal après fermeture de l'agrafe, lesdites extrémités ayant une configuration horizontale en harpon pour s'insérer dans l'épaisseur du treillis métallique et assurer la liaison de ladite agrafe.According to a first characteristic of the invention, the device for stapling seals for cooking ovens is characterized in that it comprises a plurality of staples which are capable of being positioned, inserted into at least the thickness of the textile lining and a possible metallic mesh of the joint, each staple having a V-shaped configuration, with two symmetrical branches, having a recessed portion forming a narrowing capable of being located in the thickness of the textile lining and the metallic mesh , said recessed shape itself extending by two ends capable of juxtaposing in a horizontal plane after closing the staple, said ends having a horizontal harpoon configuration to fit into the thickness of the wire mesh and ensure the connection of said clip.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These characteristics and others will become apparent from the following description.

Pour fixer l'objet de l'invention illustré d'une manière non limitative aux figures des dessins où :

  • La figure 1 est une vue en perspective d'une agrafe selon l'art antérieur.
  • La figure 2 est une vue en coupe illustrant le montage de l'agrafe selon l'art antérieur.
  • La figure 3 est une vue en perspective de l'agrafe selon l'invention en position ouverte.
  • La figure 4 est une vue de l'agrafe en position fermée.
  • La figure 5 est une vue de dessus de l'agrafe.
  • La figure 6 est une vue de profil de l'agrafe en position fermée.
  • La figure 7 est une vue illustrant l'apposition de l'agrafe sur un joint pour four de cuisson.
To fix the subject of the invention illustrated in a nonlimiting manner in the figures of the drawings where:
  • Figure 1 is a perspective view of a clip according to the prior art.
  • Figure 2 is a sectional view illustrating the mounting of the clip according to the prior art.
  • Figure 3 is a perspective view of the clip according to the invention in the open position.
  • Figure 4 is a view of the clip in the closed position.
  • Figure 5 is a top view of the clip.
  • Figure 6 is a side view of the clip in the closed position.
  • Figure 7 is a view illustrating the affixing of the clip on a seal for a cooking oven.

Selon l'invention, le dispositif d'agrafage comprend ainsi une pluralité d'agrafes (6) qui sont susceptibles d'être positionnées et introduites dans l'épaisseur de la garniture textile (3) du joint ainsi que le treillis métallique (2) s'il est présent.According to the invention, the stapling device thus comprises a plurality of staples (6) which are capable of being positioned and introduced into the thickness of the textile lining (3) of the joint as well as the wire mesh (2) if he is present.

Chaque agrafe présente une configuration en V avec ses branches (6a, 6b) à capacité élastique de déformation, permettant le clipsage de l'agrafe dans les ouvertures (5) de l'encadrement de porte. Les deux branches (6a, 6b) de l'agrafe sont symétriques. Elles comprennent une zone en retrait (6c) formant, lorsque l'agrafe est fermée, une zone de rétrécissement située dans l'épaisseur de la garniture textile et du treillis métallique. Lesdites formes en retrait sont prolongées aux extrémités des branches par deux formes en crochets (6d) recourbées, dont les extrémités sont susceptibles de se juxtaposer et/ou de se chevaucher lorsque l'agrafe est fermée. Lesdites extrémités des branches sont agencées avec une forme en harpon en définissant en particulier une zone (6e) de retenue dans le treillis métallique. Ces formes en harpon ont une configuration en triangle isocèle avec un décrochement mettant en valeur une zone d'accrochage du treillis métallique. La partie de liaison entre l'extrémité harponnée et la zone du retrait précité peut être de largeur dégressive ou constante. Ladite agrafe ainsi réalisée est donc agencée en étant parfaitement tenue sur le joint grâce à la configuration particulière de ses extrémités formant harpon.Each clip has a V-shaped configuration with its branches (6a, 6b) with elastic deformation capacity, allowing the clip to be clipped into the openings (5) of the door frame. The two branches (6a, 6b) of the clip are symmetrical. They include a recessed area (6c) forming, when the clip is closed, a narrowing area located in the thickness of the textile lining and the wire mesh. Said recessed shapes are extended at the ends of the branches by two curved hook shapes (6d), the ends of which are capable of juxtaposing and / or overlap when the staple is closed. Said ends of the branches are arranged with a harpoon shape, in particular defining a retaining zone (6e) in the wire mesh. These harpoon shapes have an isosceles triangle configuration with an offset highlighting an attachment zone of the wire mesh. The connecting part between the harpooned end and the abovementioned withdrawal zone may be of decreasing or constant width. Said clip thus produced is therefore arranged while being perfectly held on the joint thanks to the particular configuration of its ends forming a harpoon.

Lorsque ladite agrafe est positionnée sur le joint à travers la garniture textile et le treillis métallique, elle n'est pas enlevable en elle-même, sauf à créer une détérioration sur ladite garniture textile et/ou du treillis métallique.
Les avantages ressortent bien de l'invention. On souligne la simplicité de mise en oeuvre de l'agrafe et son faible coût de fabricationWhen said clip is positioned on the joint through the textile lining and the wire mesh, it is not removable in itself, except to create a deterioration on said textile lining and / or of the wire mesh.
The advantages emerge clearly from the invention. We emphasize the simplicity of implementation of the clip and its low manufacturing cost
