Description

L'invention concerne une boucle d'attache à ouverture rapide perfectionnée de deux sangles entre elles, dites respectivement "sangle fixe" et "sangle de réglage".The invention relates to a fastening loop fast opening improved two straps between them, called respectively "fixed strap" and "adjustment strap".

De telles boucles à ouverture rapide sont bien connues. Il n'est donc pas utile de les décrire ici en détail (voir par exemple documents DE-A-511 410 et 1 199 937, US-A-4 150 464 et 4 831 694), les deux derniers documents divulguant le préambule de la revendication 1.Such quick opening buckles are well known. It is therefore not useful to describe them here in detail (see for example documents DE-A-511 410 and 1 199 937, US-A-4 150 464 and 4 831 694), the last two documents disclosing the preamble of claim 1.

Pour l'essentiel, ce type de boucle est constitué :

  • d'une part, d'une partie mâle formée d'une embase de raccordement à la sangle de réglage, en forme de fenêtre, comportant une entretoise sur laquelle passe la sangle, ladite embase étant associée à une fourchette constituée d'un doigt central de guidage et de deux doigts élastiques latéraux symétriques de clipsage;
  • et d'autre part, d'une partie femelle comprenant une embase dans laquelle vient s'engager l'extrémité de la sangle fixe, ladite embase étant associée à une coquille ouverte à l'avant, formée de deux flasques respectivement supérieur et inférieur, ladite coquille présentant deux ouvertures latérales qui coopèrent avec l'extrémité des doigts élastiques.
Essentially, this type of loop consists of:
  • on the one hand, a male part formed by a connection base to the adjustment strap, window-shaped, comprising a spacer on which the strap passes, said base being associated with a fork consisting of a central finger guide and two symmetrical lateral elastic clips for clipping;
  • and on the other hand, a female part comprising a base in which the end of the fixed strap engages, said base being associated with a shell open at the front, formed by two flanges respectively upper and lower, said shell having two lateral openings which cooperate with the end of the elastic fingers.

L'invention vise une version perfectionnée de ce type de boucle d'attache à ouverture rapide.The invention relates to an improved version of this type of fast-opening attachment loop.

Selon l'invention, le flasque supérieur de la coquille comporte un prolongement, dépassant de l'ouverture frontale, destiné, une fois les deux parties engagées l'une dans l'autre, à recouvrir le dessus de l'embase de la partie mâle sensiblement jusqu'à l'extrémité de celle-ci.According to the invention, the upper flange of the shell has an extension, protruding from the front opening, intended, once the two parts engaged one in the other, to cover the top of the base of the male part substantially to the end thereof.

En d'autres termes, l'invention consiste à prolonger la coquille supérieure de la partie femelle jusqu'à ce que celle-ci recouvre sensiblement toute l'embase de la partie mâle pour ainsi assurer une bonne protection de la sangle de réglage et donner à l'ensemble des caractéristiques fonctionnelles et esthétiques originales.In other words, the invention consists in extending the upper shell of the female part until it covers substantially the entire base of the male part, thus ensuring good protection of the adjustment strap and giving to all the original functional and aesthetic characteristics.

En pratique, les deux parties mâle et femelle sont en matière plastique, tel que polyacétal ou polyamide, et le prolongement est directement venu de moulage avec le flasque supérieur de la coquille.In practice, the two male and female parts are made of plastic, such as polyacetal or polyamide, and the extension is directly molded with the upper flange of the shell.

Dans une version perfectionnée, le flasque supérieur de la coquille de la partie femelle recouvre également l'embase dans laquelle s'engage l'extrémité de la sangle fixe.In an improved version, the upper flange of the shell of the female part also covers the base in which the end of the fixed strap engages.

La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux de l'exemple de réalisation qui suit à l'appui des figures annexées.

La partie mâle (1) en matière plastique moulée est formée d'une embase (2) de raccordement à la sangle de réglage (3). Cette embase (2) en forme de fenêtre (4) comporte une entretoise (5) sur laquelle passe la sangle (3). Cette embase est associée à une fourchette, constituée de manière connue d'un doigt central de guidage (6) et de deux doigts élastiques respectivement (7) et (8) latéraux symétriques de clipsage.The male part (1) of molded plastic material is formed by a base (2) for connection to the adjustment strap (3). This window-shaped base (2) (4) has a spacer (5) over which the strap (3) passes. This base is associated with a fork, constituted in a known manner by a central guide finger (6) and two elastic fingers respectively (7) and (8) symmetrical lateral clipping.

Dans une forme de réalisation avantageuse, l'entretoise (5) présente une section triangulaire pointe dirigée vers le bas, et les faces en regard de la portion arrière (25) de la fenêtre (4) et de l'entretoise (5) sont parallèles pour assurer un bon blocage de la sangle de réglage (3). De même, le doigt central de guidage (6) peut présenter une section longitudinale en forme de trapèze.In an advantageous embodiment, the spacer (5) has a triangular cross section pointed downwards, and the facing faces of the rear portion (25) of the window (4) and of the spacer (5) are parallel to ensure good locking of the adjustment strap (3). Similarly, the central guide finger (6) may have a longitudinal section in the shape of a trapezoid.

La partie femelle (10) est formée d' un talon (11) comprenant une entretoise (12) autour de laquelle passe l'extrémité de la sangle fixe (13). Ce talon (11) est associé de manière connue à une coquille formée de deux flasques, respectivement supérieur (14) et inférieur (15), définissant sur l'avant une ouverture frontale (16). Dans la forme de réalisation pratique exemplifiée, la coquille supérieure (14) recouvre en (17) le talon (11), cachant ainsi la sangle fixe (13). De manière connue, cette partie femelle (10) présente deux ouvertures latérales (30,31) arrondies qui pour la fermeture (ou l'ouverture), coopèrent avec l'extrémité des doigts élastiques (7,8) et en limitent le débattement.The female part (10) is formed by a heel (11) comprising a spacer (12) around which the end of the fixed strap (13) passes. This heel (11) is associated in a known manner with a shell formed by two flanges, respectively upper (14) and lower (15), defining a front opening (16) on the front. In the exemplary practical embodiment, the upper shell (14) covers at (17) the heel (11), thus hiding the fixed strap (13). In known manner, this female part (10) has two rounded lateral openings (30,31) which, for closing (or opening), cooperate with the end of the elastic fingers (7,8) and limit the movement thereof.

Selon la caractéristique originale de l'invention, le flasque supérieur (14) comporte un prolongement (20) dépassant l'ouverture frontale (16) et destiné, une fois les deux parties mâle et femelle (1,10) engagées l'une dans l'autre, à recouvrir le dessus de l'embase (2) de la partie mâle (1), sensiblement jusqu'à l'aplomb de l'extrémité de la portion arrière (25) de la fenêtre (2). En d'autres termes, l'extrémité avant (26) du prolongement concentrique (20) est située (voir figure 2) sensiblement à l'aplomb de l'extrémité arrière (25) de la fenêtre (2) de la partie mâle (1).According to the original characteristic of the invention, the upper flange (14) has an extension (20) beyond the front opening (16) and intended, once the two male and female parts (1,10) engaged one in the other, to cover the top of the base (2) of the male part (1), substantially up to the plumb of the end of the rear portion (25) of the window (2). In other words, the front end (26) of the concentric extension (20) is located (see FIG. 2) substantially perpendicular to the rear end (25) of the window (2) of the male part ( 1).

Comme montré à la figure 1, le prolongement caractéristique (20) venu de moulage avec le flasque supérieur (14), présente deux petites ailettes latérales (27,28) en forme de retour pour recouvrir le haut des côtés de l'embase (2).As shown in Figure 1, the characteristic extension (20) molded with the upper flange (14), has two small lateral fins (27,28) in the form of a return to cover the top of the sides of the base (2 ).

Dans une forme de réalisation non illustrée, la face intérieure (40) du prolongement caractéristique (20) et la face intérieure du flasque supérieur (14) présentent des rainures parallèles de guidage venues de moulage pour faciliter l'introduction ou le retrait de la partie mâle (1) en coopérant avec les doigts (6,7 et 8).In an embodiment not illustrated, the internal face (40) of the characteristic extension (20) and the internal face of the upper flange (14) have parallel guide grooves which have been molded in order to facilitate the introduction or the withdrawal of the part. male (1) by cooperating with the fingers (6,7 and 8).

Le prolongement caractéristique (20) assure une meilleure protection de la sangle de réglage (3), notamment contre l'usure par frottements, et confère à l'ensemble un esthétique diversifié et amélioré.The characteristic extension (20) provides better protection of the adjustment strap (3), in particular against wear by friction, and gives the assembly a diversified and improved aesthetic.

De plus, ce prolongement (20) assure un meilleur guidage de la partie mâle (1) dans la partie femelle (10). Par ailleurs, ce prolongement caractéristique (20) évite, en cours de portage, la confusion entre les boucles de réglage de sangles et les boucles de fermeture. Enfin, ce prolongement (20) augmente la surface apparente du flasque supérieur (14) de la coquille, ce qui permet de recevoir un marquage tel qu'un logotype ou un dispositif réfléchissant) plus important.In addition, this extension (20) ensures better guidance of the male part (1) in the female part (10). Furthermore, this characteristic extension (20) avoids, during carrying, confusion between the strap adjustment loops and the closure loops. Finally, this extension (20) increases the apparent surface of the upper flange (14) of the shell, which makes it possible to receive a larger marking such as a logotype or a reflecting device.

De la sorte, cette boucle d'attache à ouverture rapide perfectionnée peut recevoir toutes les applications connues pour ce type de boucle, tel que sac à dos, gilet de sauvetage, matériel de montagne, ceinture, sangle, etc..In this way, this improved quick opening fastening loop can receive all the applications known for this type of loop, such as backpack, life jacket, mountain equipment, belt, strap, etc.
