Abstract

The extruded strip seal in vulcanized thermo- welding material consists of a foot (1) containing a retention extension (5), from which extends a lip (9,10,11,12). The lip is bent (10) in a manner that the free edge (12) is further from the foot (1) than the rest of the lip. The seal is inserted in a recess around a window frame and at the corners, where the horizontal and vertical strips butt, they are welded and deburred to produce a good seal.

Description

Joint profilé. notamment pour châssis de fentre s'opposant au vent
La présente invention se rapporte aux joints profites et, plus particutièrement, à ceux utilisés dans les châssis de fentre.Profile seal. especially for window frames against the wind
The present invention relates to the advantageous seals and, more particularly, to those used in window frames.

On connaît déjà un joint profilé en une matière élastomère thermosoudable. Ce joint comprend un pied qui est muni d'au moins une saillie de retenue, généralement de deux saillies, permettant de retenir le joint dans une nervure d'une pièce de châssis de fentre. Une lèvre est issue du pied. A profiled seal is already known in a heat-sealable elastomeric material. This seal comprises a foot which is provided with at least one retaining projection, generally two projections, making it possible to retain the seal in a rib of a window frame part. A lip comes from the foot.

L'extrémité libre de cette lèvre est destinée à s'appliquer sur une pièce du châssis de fentre en regard de la pièce comportant la rainure pour assurer t'étanchéité.The free end of this lip is intended to be applied to a part of the window frame opposite the part comprising the groove to ensure sealing.

Comme le joint est en une matière thermosoudable vulcanisée, les profites de châssis de fentre peuvent tre fabriqués en usine et livrés remontes. A l'atelier de menuiserie, les profites horizontaux et verticaux sont soudés, ce qui donne lieu à des bavures, notamment dans les coins de liaison d'un profilé vertical et d'un profilé horizontal, qu'il faut ébavurer pour conserver une bonne étanchéité. Si la lèvre est dirigée dans le sens opposé au courant d'air provoqué par le vent, elle est très efficace pour s'opposer au vent puisque celui-ci tend à I'appuyer sur la pièce sur laquelle elle vient en contact, mais les travaux d'ébavurage sont très difficiles à effectuer parce qu'on n'a accès que difficilement aux points de soudure et aux bavures. Si, en revanche, la lèvre est dans I'autre sens, on peut ébavurer plus facilement, mais le vent a tendance à détacher la livre de la surface avec laquelle elle est en contact et à pénétrer à l'intérieur des habitations. As the seal is made of a vulcanized heat-sealable material, the window frame benefits can be manufactured in the factory and delivered reassembled. In the carpentry workshop, the horizontal and vertical profits are welded, which gives rise to burrs, especially in the connecting corners of a vertical profile and a horizontal profile, which must be deburred to keep a good sealing. If the lip is directed in the opposite direction to the air current caused by the wind, it is very effective in opposing the wind since it tends to press it on the part on which it comes into contact, but the Deburring work is very difficult to perform because it is difficult to access the welding points and burrs. If, on the other hand, the lip is in the other direction, it is possible to deburr more easily, but the wind tends to detach the pound from the surface with which it is in contact and to penetrate inside dwellings.

L'invention pallie ces inconvénients par un joint qui, tout en s'opposant efficacement au vent, permet de faciliter t'ébavurage.  The invention overcomes these drawbacks by a seal which, while effectively opposing the wind, facilitates deburring.

L'invention a donc pour objet un joint profilé en une matière élastomère thermosoudable vulcanisée, comprenant un pied qui est muni d'une saillie de retenue et duquel est issue une lèvre. Suivant l'invention, la lèvre est coudée et ce, de sorte que le bord libre de la lèvre soit plus éloigné du pied que le reste de la lèvre. The invention therefore relates to a profiled seal made of a vulcanized heat-sealable elastomeric material, comprising a foot which is provided with a retaining projection and from which a lip comes. According to the invention, the lip is bent and this, so that the free edge of the lip is further from the foot than the rest of the lip.

Grâce à ce coude, on conserve la bonne direction du premier tronçon de la lèvre facilitant t'ébavurage, mais par le coude on retrouve la bonne direction suivant laquelle s'applique l'extrémité libre du joint sur la pièce opposée permettant de bien résister au vent. Thanks to this bend, the right direction of the first section of the lip is maintained, facilitating deburring, but by the bend we find the right direction in which the free end of the seal is applied to the opposite part, making it possible to resist the wind.

Selon un perfectionnement, la lèvre est en une matière plus souple que la matière constituant le pied. Le pied peut ainsi tenir mieux dans la rainure après qu'il y a été engagé, tandis que la lèvre conserve une plus grande mémoire élastique qui permet d'avoir une meilleure efficacité et une plus grande longévité. Le pied est notamment en potypropytène copolymère de dureté 30 Shore D environ, tandis que la lèvre est en thermoplastique élastomère vulcanisée de dureté 70 Shore A environ. According to an improvement, the lip is made of a more flexible material than the material constituting the foot. The foot can thus hold better in the groove after it has been engaged therein, while the lip retains a greater elastic memory which allows for better efficiency and greater longevity. The base is in particular made of potypropytene copolymer with a hardness of about 30 Shore D, while the lip is made of vulcanized elastomeric thermoplastic with a hardness of about 70 Shore A.

Pour donner de la résistance à la traction au pied, un fil en matière résistant à la traction, notamment en fibre de verre, y est enrobé. Le fil est dérouté dans la filière lors de t'extrusion du pied. To give tensile strength to the foot, a wire made of tensile material, in particular fiberglass, is coated therein. The thread is diverted into the die when the foot is extruded.

On a obtenu de bon résultat, suivant l'invention, lorsque le tronçon de la lèvre, issu du pied, fait avec un plan de symétrie du pied un angle compris entre 20 et 70 et lorsque le tronçon de la lèvre, comportant le bord libre, fait avec le plan de symétrie du pied un angle compris entre 20 et 70
Les angles indiqués ne signifient pas nécessairement que les tronçons de la lèvre ont des faces planes, mais indiquent simplement la direction générale de ces tronçons et, tout particulièrement, la direction de la face des tronçons tournée vers l'intérieur qui est I'aval dans le sens du courant d'air.Good results have been obtained, according to the invention, when the section of the lip, coming from the foot, makes an angle of between 20 and 70 with a plane of symmetry of the foot and when the section of the lip, comprising the free edge , made with the plane of symmetry of the foot an angle between 20 and 70
The angles indicated do not necessarily mean that the sections of the lip have planar faces, but simply indicate the general direction of these sections and, in particular, the direction of the face of the sections facing inwards which is the downstream the direction of the air flow.

L'invention vise également un châssis de fentre comprenant un passage définit entre une première pièce et une seconde pièce comportant une rainure, le passage permettant à un courant d'air de passer de l'extérieur de la fentre à l'intérieur, un joint suivant l'invention étant toge dans la rainure et s'etendant dans le passage et l'extrémité libre du joint étant tournée vers I'amont.  The invention also relates to a window frame comprising a passage defined between a first part and a second part comprising a groove, the passage allowing a current of air to pass from the outside of the window to the inside, a seal. according to the invention being toga in the groove and extending in the passage and the free end of the joint being turned upstream.

Au dessin annexé, donné uniquement à titre d'exemple :
la figure 1 est une vue en coupe d'un joint suivant l'invention, tandis que
la figure 2 est une vue en coupe d'un châssis de fentre suivant l'invention.In the attached drawing, given solely by way of example:
Figure 1 is a sectional view of a seal according to the invention, while
Figure 2 is a sectional view of a window frame according to the invention.

Le joint profilé, représente en coupe transversale à la figure 1, comporte un pied 1 de symétrie par rapport à un plan XX'correspondant à la direction d'introduction du joint dans une rainure. Le pied comprend un nez 2 avant, deux parois latérales 3,4 desquelles sont issues des saillies 5 et une base 6. Le nez 2, les parois 3,4 latérales et la base 6 définissent une cavité 7 facilitant t'extrusion et donnant de t'étasticité. ce qui permet d'enfoncer plus facilement le joint dans une rainure. Le pied est en polypropylène copolymère. The profiled seal, shown in cross section in Figure 1, has a foot 1 of symmetry with respect to a plane XX 'corresponding to the direction of introduction of the seal into a groove. The foot comprises a nose 2 before, two side walls 3,4 from which come from the projections 5 and a base 6. The nose 2, the side walls 3,4 and the base 6 define a cavity 7 facilitating the extrusion and giving elasticity. which makes it easier to push the seal into a groove. The foot is made of copolymer polypropylene.

Dans la base du pied est enrobé un fil 8 en fibre de verre qui s'étend tout le long du profité. In the base of the foot is coated a fiberglass wire 8 which extends all along the profit.

Du point de la base 6 se trouvant dans le plan XX'est issue une lèvre comprenant un premier tronçon 9 qui fait avec le plan XX'de symétrie un angle de 50 environ. Ce tronçon 9 se prolonge après un coude 10 par un tronçon 11 qui fait avec le plan XX'un angle de 45 environ. L'extrémité libre 12 du tronçon 11 est arrondie. La levre est en une matière thermoplastique élastomère. From the point of the base 6 lying in the plane XX ', there comes a lip comprising a first section 9 which forms an angle of approximately 50 with the plane XX' of symmetry. This section 9 is extended after a bend 10 by a section 11 which forms an angle of approximately 45 with the plane XX ′. The free end 12 of the section 11 is rounded. The lip is made of an elastomeric thermoplastic material.

A la figure 2, on reconnaît un châssis de fentre comportant un dormant 13 et un ouvrant 14 lequel définit une feuillure 15 portant un vitrage 16. L'ouvrant définit une rainure 17 en regard d'une pièce 18 du dormant. Un passage est ménagé entre la rainure 17 et la pièce 18 et de I'air peut passer par des interstices entre le dormant 13 et l'ouvrant 14 pour aller, en passant par le passage entre la rainure 17 et la pièce 18, de l'extérieur de la fentre jusqu'à l'intérieur. Pour s'opposer à ce passage, le pied 20 d'un joint suivant l'invention est inséré dans la rainure 17 et son bord libre 21 s'appuie sur la pièce 18, le bord 21 étant tourné vers l'amont dans le sens de passage du courant d'air de l'extérieur vers l'intérieur.  In Figure 2, there is a window frame comprising a frame 13 and an opening 14 which defines a rebate 15 carrying a window 16. The opening defines a groove 17 opposite a part 18 of the frame. A passage is formed between the groove 17 and the part 18 and air can pass through interstices between the frame 13 and the leaf 14 to go, passing through the passage between the groove 17 and the part 18, from the outside the window to the inside. To oppose this passage, the foot 20 of a seal according to the invention is inserted in the groove 17 and its free edge 21 is supported on the part 18, the edge 21 being turned upstream in the direction air flow from outside to inside.
