A flexible hinge (4) is fixed between the two recesses.

Description

La présente invention concerne un dispositif destiné à assurer le serrage et le desserrage d'accessoires ou parties d'accessoires mettant en oeuvre des cordes, cordons et cordelettes. Ce dispositif, présente un certain nombre d'avantages, il permet par exemple, d'obtenir un serrage rapide des produits qu'il équipe en supprimant les traditionnelles phases de serrage des serre-cordon « classiques ». Les vieux systèmes de serre cordon ont fait leur preuve, mais n'ont pas su se renouveler tant au niveau de l'ergonomie, de la réduction de leur nombre de pièces ou de leur intégration au support. Le dispositif selon l'invention permet de répondre à ces besoins, il comporte en effet selon une première caractéristique un corps de plastique dont l'architecture et le 10 fonctionnement rappelle celui d'une pince à linge. Selon une deuxième caractéristique le dispositif possède des aménagements comme une ouverture circulaire et des dents, permettant d'une part de canaliser le cordon qu'il reçoit et d'autre part d'assurer son serrage ou son desserrage.The present invention relates to a device for ensuring the tightening and loosening of accessories or parts of accessories using ropes, cords and cords. This device, has a number of advantages, it allows for example, to obtain a rapid tightening of the products it equips by removing the traditional clamping phases of the "conventional" cord clamps. The old cord clamp systems have proved their worth, but have not been able to renew themselves in terms of ergonomics, reducing their number of parts or integration into the support. The device according to the invention makes it possible to meet these needs, it comprises in fact, according to a first characteristic, a plastic body whose architecture and operation recalls that of a clothespin. According to a second characteristic, the device has arrangements such as a circular opening and teeth, making it possible on the one hand to channel the cord that it receives and, on the other hand, to ensure its tightening or loosening.

15 Les dessins annexés, illustrent l'invention : La figure 1 représente le dispositif en vue avant. La figure 2 représente le dispositif en vue arrière. La figure 3 représente le dispositif en vue de côté. La figure 4 représente le dispositif en vue de dessus.The accompanying drawings illustrate the invention: FIG. 1 shows the device in front view. Figure 2 shows the device in rear view. Figure 3 shows the device in side view. Figure 4 shows the device in plan view.

20 La figure 5 représente le dispositif en vue de dessous La figure 6 représente le dispositif en vue axonométrique. La figure 7 représente une coupe sur le dispositif. En référence à ces dessins, le dispositif est constitué d'une pièce de plastique, dont le 25 profil général rappel la forme d'une pince à linge. Ce dispositif est un volume de section circulaire ou de toutes autres formes, possédant dans sa partie haute et dans sa partie basse deux évidements de matière lui donnant ses caractéristiques de pince. L'évidement supérieur (1), (fig. 6) crée une tranchée verticale et centrale coupant la pièce transversalement de part en part. Cet évidement supérieur (1) se développe du sommet de la pièce jusqu'à un peu 30 avant la fin du tiers de sa partie haute, ouvrant ainsi celle-ci en deux et formant deux massifs (2), (fig. 6). L'évidement inférieur (3), (fig. 6) est réalisé sur la base d'un plan trapézoïdale et traverse la pièce transversalement de part en part dans la même direction que l'évidement supérieur (1). Cet évidement inférieur (3) se développe de la base de la pièce jusqu'à un peu avant la fin des deux tiers de sa partie basse. Ces deux évidements ne laissent entre eux qu'un peu de matière formant ainsi de fait une zone de moindre épaisseur qui est une charnière souple (4), (fig. 6) solidarisant deux parties distinctes. Selon cette structuration, la pièce présente donc dans sa partie basse deux pattes (5), (fig. 6) et dans sa partie haute deux massifs (2). Dans la partie haute du dispositif, les faces internes de chaque massif (2) sont dotées d'une dent (6), (fig. 6) au profil de triangle rectangle dont l'hypoténuse est orientée vers le bas. Ces deux dents (6) qui se font face et qui ne laissent entre eux qu'un faible espace, ont leur côté haut confondu avec le sommet horizontal du dispositif et forme ainsi une mâchoire. La charnière souple (4) est percée d'une ouverture circulaire (7), (fig. 4) qui la traverse, de part en part, dans le sens vertical ou longitudinal de la pièce. Le profil de cette ouverture circulaire (7) est projetée également vers le haut jusqu'à la base des dents (6) ce qui génère deux gorges supérieures (8), (fig. 7) inscrites dans les faces internes de chaque massif (2). Deux gorges inférieures (9), (fig. 7) prennent place sous l'ouverture circulaire (7) et viennent creuser les faces internes des pattes (5), elles sont générées selon un cercle au diamètre légèrement supérieur à cette dernière. Un des massif (2) est équipé de deux protubérances, les bras de contention (10), (fig. 6), qui viennent entourer les dents (6) conformément à la section circulaire de la pièce et se prolongent jusqu'à venir empiéter sur le massif (2) opposé qui est creusé pour la circonstance des formes correspondantes. Le rôle des bras de contention (10) est de contraindre le cordon à rester entre les dents (6) du dispositif. Chacune des pattes (5) est percée d'une saillie verticale qui est un passant (11) (fig. 6) destiné à recevoir un ruban de tissu permettant de fixer le dispositif sur un support quelconque. Le dispositif ainsi défini permet d'accueillir un cordon que l'on peut enfiler par le trou circulaire (7) de la charnière souple (4) en le faisant remonter jusqu'à le faire passer entre les deux dents (6) de la partie supérieure. Une fois que le cordon est passé à travers tout le dispositif, celui-ci est prêt à fonctionner. On constate qu'il s'agit d'un système anti retour. Effectivement on peut tirer le cordon dans un sens ce qui permet de le serrer instantanément et ce, sans exercer de pression préalable sur un système mécanique quelconque. Le cordon ne peut refluer en raison du profil des dents (6) qui autorisent son passage dans un sens, mais pas dans l'autre. Pour libérer le cordon il suffit d'exercer une pression sur les pattes (5) ce qui va provoquer l'écartement des dents (6) et libérer celui-ci.Fig. 5 shows the device in bottom view. Fig. 6 shows the device in axonometric view. Figure 7 shows a section on the device. With reference to these drawings, the device consists of a piece of plastic, the general profile of which resembles the shape of a clothespin. This device is a volume of circular section or any other shape, having in its upper part and in its lower part two material recesses giving it its clamp characteristics. The upper recess (1), (Fig. 6) creates a vertical and central trench cutting the work transversely from one side to the other. This upper recess (1) develops from the top of the piece until a little before the end of the third of its upper part, thereby opening the latter in two and forming two masses (2), (Figure 6). The lower recess (3), (Fig. 6) is formed on the basis of a trapezoidal plane and crosses the workpiece transversely from one side to the other in the same direction as the upper recess (1). This lower recess (3) develops from the base of the room until a little before the end of two thirds of its lower part. These two recesses leave between them only a little material thus forming a zone of lesser thickness which is a flexible hinge (4), (FIG 6) solidarisant two distinct parts. According to this structuring, the piece thus has in its lower part two tabs (5), (FIG 6) and in its upper part two masses (2). In the upper part of the device, the internal faces of each solid mass (2) are provided with a tooth (6), (Fig.6) with a right-angled triangle profile whose hypotenuse is oriented downwards. These two teeth (6) facing each other and leaving only a small gap between them, have their upper side confused with the horizontal vertex of the device and thus forms a jaw. The flexible hinge (4) is pierced with a circular opening (7), (FIG 4) which passes through it, from side to side, in the vertical or longitudinal direction of the piece. The profile of this circular opening (7) is also projected upwards to the base of the teeth (6) which generates two upper grooves (8), (FIG 7) inscribed in the internal faces of each solid mass (2). ). Two lower grooves (9), (FIG 7) take place under the circular opening (7) and come to dig the inner faces of the legs (5), they are generated in a circle with a diameter slightly greater than the latter. One of the solid masses (2) is equipped with two protuberances, the support arms (10) (Fig 6), which surround the teeth (6) in accordance with the circular section of the workpiece and extend until they come to encroach on the massive (2) opposite which is dug for the circumstance of corresponding forms. The role of the restraining arms (10) is to constrain the cord to remain between the teeth (6) of the device. Each of the tabs (5) is pierced with a vertical projection which is a loop (11) (FIG 6) for receiving a fabric tape for fixing the device on any support. The device thus defined can accommodate a cord that can be threaded through the circular hole (7) of the flexible hinge (4) by raising it to pass it between the two teeth (6) of the part higher. Once the cord has passed through the entire device, it is ready for use. We see that it is an anti-return system. Indeed we can pull the cord in one direction which allows to tighten it instantly and without exerting pressure on any mechanical system. The cord can not flow back because of the profile of the teeth (6) that allow its passage in one direction, but not in the other. To release the cord simply exert pressure on the legs (5) which will cause the spacing of the teeth (6) and release it.
