Description

Dispositif de retenue démontable en matière thermoplastique w Domaine technique de l'invention Removable retainer made of thermoplastic material Technical field of the invention

L'invention est relative à un dispositif de retenue démontable en matière thermoplastique extrudée, comportant une paire de bandes de fixation montées en tête-bêche et pouvant être rattachées l'une à l'autre par 15 imbrication mutuelle, chaque bande étant composée d'une surface d'appui et d'un profilé équipé de deux pattes souples d'accrochage espacées l'une de l'autre pour délimiter des logements complémentaires destinés à l'encliquetage des pattes de la bande adjacente de structure identique. The invention relates to a removable retaining device of extruded thermoplastic material, comprising a pair of fixing strips mounted upside down and which can be attached to one another by mutual interleaving, each strip being composed of a bearing surface and a section equipped with two flexible fastening tabs spaced apart from each other to delimit complementary housing for snapping the legs of the adjacent strip of identical structure.

20 État de la technique 20 State of the art

Le document FR 2613326 décrit un dispositif de fermeture séparable du genre mentionné, destiné à la fixation des bandes de fermeture sur des substrats, notamment des films ou des feuilles pour la fabrication de sacs 25 refermables. La matière thermoplastique peut être à base de polypropylène, ou de polyéthylène. Les nervures profilées souples de chaque bande sont identiques, et s'engagent sans jeu dans des logements complémentaires de l'autre bande. Document FR 2613326 discloses a separable closure device of the kind mentioned, intended for fixing the closure strips on substrates, in particular films or sheets for the manufacture of resealable bags. The thermoplastic material may be based on polypropylene, or polyethylene. The flexible profiled ribs of each band are identical, and engage without play in complementary housing of the other band.

30 Dans un autre système de retenue séparable et refermable, il est connu de prévoir un décrochement dans la surface d'appui, le décrochement s'étendant obliquement par rapport à la patte d'accrochage intermédiaire de In another separable and reclosable retaining system, it is known to provide a recess in the bearing surface, the recess extending obliquely relative to the intermediate gripping tab of

chaque profilé. Les deux pattes d'accrochage de chaque profilé sont identiques, et s'engagent avec jeu dans les logements complémentaires autorisant le coulissement bidirectionnel des deux bandes dans la direction d'extension des profilés. Les surfaces d'appui ont néanmoins tendance à se déformer au niveau du décrochement lors de l'apparition de contraintes mécaniques dues à des forces de traction multidirectionnelles s'exerçant sur les bandes. Cette déformation peut entraîner un effet de glissement dans la direction d'extension des pattes d'accrochage au détriment de l'interverrouillage des deux bandes. each profile. The two fastening tabs of each section are identical, and playfully engage in the complementary housing allowing the bidirectional sliding of the two strips in the direction of extension of the profiles. The bearing surfaces nevertheless tend to deform at the recess when mechanical stresses arise due to multidirectional tensile forces acting on the strips. This deformation can cause a sliding effect in the direction of extension of the attachment tabs to the detriment of the interlocking of the two bands.

Objet de l'invention Object of the invention

L'objet de l'invention consiste à réaliser un dispositif de retenue à bandes de fixation imbriquées ayant un accrochage optimal indépendamment des contraintes mécaniques s'exerçant entre les bandes. The object of the invention is to provide a retaining device with interleaved fastening strips having an optimal attachment independent of the mechanical stresses exerted between the bands.

Le dispositif selon l'invention est caractérisé en ce que la première patte d'accrochage de chaque profilé comporte un bec d'extrémité, tandis que la deuxième patte d'accrochage possède une protubérance arrondie, laquelle est disposée entre ledit bec et un bossage faisant saillie de la surface d'appui pour servir de butée renforçant le verrouillage des deux profilés en position encliquetée. The device according to the invention is characterized in that the first hooking lug of each profile has an end nose, while the second hooking lug has a rounded protrusion, which is arranged between said nose and a boss making protrusion of the bearing surface to serve as a stop reinforcing the locking of the two sections in the latched position.

La présence de cette butée permet d'obtenir un effet de coincement des deux bandes de fixation soumises à des efforts de traction, évitant tout mouvement de glissement des pattes de fixation dans les logements. Le degré de coincement est sensiblement proportionnel au rapport des forces s'exerçant sur les deux bandes. The presence of this stop makes it possible to obtain a wedging effect of the two fastening strips subjected to tensile stresses, avoiding any sliding movement of the fastening tabs in the housings. The degree of jamming is substantially proportional to the ratio of the forces acting on the two bands.

Selon un mode de réalisation préférentiel, la surface d'appui d'au moins une bande de fixation est plane, et est revêtue à l'extrémité opposée du profilé According to a preferred embodiment, the bearing surface of at least one fixing strip is flat, and is coated at the opposite end of the profile.

d'une couche d'adhésif destinée à être collée à un objet correspondant. Le bossage comporte une rampe incurvée constituant une surface progressive de frottement délimitant avec la deuxième patte d'accrochage un logement de réception de la première patte de l'autre profilé. Un tel dispositif de retenue peut être avantageusement utilisé pour fixer et démonter rapidement des feuilles de grandes surfaces sur des panneaux de support. a layer of adhesive to be glued to a corresponding object. The boss comprises a curved ramp constituting a progressive friction surface delimiting with the second attachment lug a receiving housing of the first leg of the other profile. Such a retainer may be advantageously used to quickly attach and disassemble large area sheets on support panels.

Description détaillée de l'invention Detailed description of the invention

Sur les figures 1 et 2, un dispositif de retenue 10 démontable comporte une 25 paire de bandes de fixation 11, 11A de structures identiques et réalisées en une matière thermoplastique extrudée. Les deux bandes de fixation 11, 11A sont montées en tête-bêche, et peuvent être rattachées l'une à l'autre par imbrication mutuelle. In Figures 1 and 2, a removable retainer 10 comprises a pair of fastening strips 11, 11A of identical structures and made of an extruded thermoplastic material. The two fastening strips 11, 11A are mounted upside down, and can be attached to one another by mutual interleaving.

30 Le matériau thermoplastique utilisé pour l'extrusion peut être à base de polypropylène, de polyéthylène ou de PVC.5 The thermoplastic material used for the extrusion may be based on polypropylene, polyethylene or PVC.5

Chaque bande de fixation 11, 11A est composée d'une surface d'appui 12, 12A plane, et d'un profilé 13, 13A double équipé de deux pattes d'accrochage 14, 15 ;14A, 15A souples, espacées l'une de l'autre dans la direction longitudinale. Elles sont légèrement inclinées par rapport à leurs surfaces d'appui 12, 12A respectives, et s'étendent parallèlement l'une à l'autre. Each fastening strip 11, 11A is composed of a flat bearing surface 12, 12A, and a profile 13, 13A double equipped with two fastening lugs 14, 15; 14A, 15A flexible, spaced one on the other in the longitudinal direction. They are slightly inclined relative to their respective bearing surfaces 12, 12A, and extend parallel to each other.

Les pattes d'accrochage 14, 15 du profilé 13 délimitent des logements 16, 17 de réception des pattes 15A, 14A du profilé 13A de la bande de fixation 11A complémentaire. The hooking tabs 14, 15 of the profile 13 delimit housing 16, 17 for receiving the tabs 15A, 14A of the profile 13A of the complementary fastening strip 11A.

De manière similaire, les pattes d'accrochage 14A, 15A du profilé 13A délimitent des logements 16A, 17A successifs de réception des pattes 15, 14 du profilé 13 de la bande de fixation 11. Les deux pattes d'accrochage 14, 15 ;14A, 15A de chaque profilé 13, 13A sont différentes l'une de l'autre. La première patte d'accrochage 14, 14A comporte un bec 18 d'extrémité, tandis que la deuxième patte 15, 15A possède une protubérance 19 arrondie. 20 La surface d'appui 12, 12A de chaque bande de fixation 11, 11A comporte en plus un bossage 20, 20A ayant une rampe 21, 21A incurvée délimitant avec la deuxième patte d'accrochage 15, 15A le logement 17, 17A destiné à recevoir la première patte d'accrochage 14A, 14 de l'autre profilé. La rampe 25 21, 21A présente un profil complémentaire à la surface externe de la première patte d'accrochage 14A, 14 . Similarly, the fastening tabs 14A, 15A of the section 13A delimit successive housings 16A, 17A for receiving the tabs 15, 14 of the section 13 of the fastening strip 11. The two fastening tabs 14, 15, 14A , 15A of each profile 13, 13A are different from each other. The first attachment lug 14, 14A has an end spout 18, while the second lug 15, 15A has a rounded protuberance 19. The bearing surface 12, 12A of each fastening strip 11, 11A further comprises a boss 20, 20A having a curved ramp 21, 21A delimiting with the second fastening tab 15, 15A the housing 17, 17A intended for receiving the first latching lug 14A, 14 of the other section. The ramp 21 21, 21A has a profile complementary to the outer surface of the first attachment tab 14A, 14.

Le bossage 20, 20A n'est pas déformable, et constitue une butée pourvue d'une surface de frottement le long de la rampe 21, 21A. Le fonctionnement du dispositif de retenue 10 démontable selon l'invention est le suivant : 30 Lors de l'assemblage par pression des deux bandes de fixation 11, 11A, la première patte d'accrochage 14 du profilé 13 s'engage dans le logement 17A ménagé entre la deuxième patte d'accrochage 15A et le bossage 20A de l'autre bande 11A. La deuxième patte d'accrochage 15 du profilé 13 s'engage dans le logement 16A ménagé entre la première patte d'accrochage 14A et la deuxième patte d'accrochage 15A de l'autre bande 11A. The boss 20, 20A is not deformable, and constitutes a stop provided with a friction surface along the ramp 21, 21A. The operation of the removable retainer 10 according to the invention is as follows: When the two fastening strips 11, 11A are assembled by pressing, the first fastening tab 14 of the profile 13 engages in the housing 17A. arranged between the second attachment lug 15A and the boss 20A of the other band 11A. The second attachment lug 15 of the section 13 engages in the housing 16A formed between the first latching lug 14A and the second latching lug 15A of the other strip 11A.

Réciproquement, la première patte d'accrochage 14A du profilé 13A s'engage dans le logement 17 agencé entre le bossage 20 et la deuxième patte d'accrochage 15 de l'autre bande 11. La deuxième patte d'accrochage 15A du profilé 13A s'engage dans le logement 16 ménagé entre les première et deuxième pattes d'accrochage 14, 15 de la bande 11. Conversely, the first latching lug 14A of the profile 13A engages in the housing 17 arranged between the boss 20 and the second latching lug 15 of the other strip 11. The second latching lug 15A of the profile 13A engaged in the housing 16 formed between the first and second latches 14, 15 of the strip 11.

En présence de forces de traction multidirectionnelles, une composante est générée dans la direction longitudinale s'étendant perpendiculairement à la direction d'extension des pattes d'accrochage. Cette composante tend à plaquer la première patte d'accrochage 14, 14A contre la rampe 21, 21A de frottement du bossage 20, 20A correspondant. Un coincement complémentaire est généré simultanément entre les pattes 15, 15A intermédiaires dans le logement 16A. Il en résulte un double effet de blocage qui inhibe tout mouvement de coulissement des bandes de fixation 11, 11A entre elles.25 In the presence of multidirectional tensile forces, a component is generated in the longitudinal direction extending perpendicularly to the direction of extension of the latching lugs. This component tends to press the first latching lug 14, 14A against the ramp 21, 21A friction boss 20, 20A corresponding. Complementary jamming is generated simultaneously between the tabs 15, 15A intermediate in the housing 16A. This results in a double locking effect which inhibits any sliding movement of the fastening strips 11, 11A between them.
