Description
La présente invention concerne un tablier de sécurité.The present invention relates to a safety apron.
ARRIÈRE-PLAN DE L’INVENTIONBACKGROUND OF THE INVENTION
On sait qu'en raison du développement croissant de la violence, que ce soit à l'occasion de manifestations organisées ou dans le cadre de la vie quotidienne, de plus en plus de magasins et d'habitations sont protégées par un tablier de sécurité comportant une série d'éléments de sécurité comprenant chacun un caisson allongé équipé de moyens de liaison articulés avec des éléments de sécurité adjacents. Pour que le tablier puisse résister à des agressions très fortes, par exemple des coups de bélier, il est habituellement considéré que les caissons doivent être entretoisés.We know that due to the growing development of violence, whether during organized events or as part of daily life, more and more shops and homes are protected by a safety apron including a series of security elements each comprising an elongate box equipped with connecting means articulated with adjacent security elements. In order for the deck to withstand very strong attacks, for example water hammers, it is usually considered that the caissons must be braced.
Toutefois, le produit obtenu est non seulement cher en raison de la quantité de matière et du temps nécessaires pour le réaliser, mais il est également alourdi par les entretoises.However, the product obtained is not only expensive because of the amount of material and the time necessary to achieve it, but it is also increased by the spacers.
OBJET DE L’INVENTIONOBJECT OF THE INVENTION
Un but de l'invention est de proposer un tablier de sécurité qui soit tout à la fois plus efficace et moins onéreux que les dispositifs existants.An object of the invention is to provide a safety apron that is both more efficient and less expensive than existing devices.
BRÈVE DESCRIPTION DE L’INVENTIONBRIEF DESCRIPTION OF THE INVENTION
En vue de la réalisation de ce but, on propose selon l’invention, un tablier de sécurité du type décrit ci-dessus, dans lequel une partie au moins des caissons contient un bloc de fibre synthétique compressée, en contact avec la paroi du caisson. De préférence les blocs de fibre synthétique comprimée remplissent totalement les caissons, et les fibres synthétiques sont des fibres d'aramides. De préférence encore les fibres synthétiques sont en poly-paraphénylène téréphtalamide. Ainsi, la raideur des caissons est augmentée et la fibre synthétique compressée assure une répartition de l'effort auquel le tablier est soumis de sorte qu'un coup de bélier est amorti. En outre, selon une constatation qui fait partie de l'invention, il a été constaté que le tablier selon l'invention a de bonnes propriétés pare-balles.In order to achieve this object, a safety apron of the type described above is proposed according to the invention, in which at least part of the boxes contain a block of compressed synthetic fiber in contact with the wall of the box. . Preferably the blocks of compressed synthetic fiber completely fill the boxes, and the synthetic fibers are aramid fibers. More preferably the synthetic fibers are poly-para-phenylene terephthalamide. Thus, the stiffness of the boxes is increased and the compressed synthetic fiber provides a distribution of the effort to which the deck is subjected so that a water hammer is damped. In addition, according to a finding that is part of the invention, it has been found that the apron according to the invention has good bulletproof properties.
Selon un autre aspect avantageux de l'invention, chaque caisson a une section identique sur toute sa longueur, et chaque caisson comprend à une extrémité une ouverture identique à la section du caisson. Les blocs de fibres synthétiques comprimées peuvent ainsi être mis en place par simple coulissement dans les caissons.According to another advantageous aspect of the invention, each box has an identical section over its entire length, and each box comprises at one end an opening identical to the section of the box. The blocks of compressed synthetic fibers can thus be put in place by simply sliding in the boxes.
Selon un mode de réalisation préféré de l'invention, chaque caisson comporte deux coques assemblées l'une à l'autre. De préférence les coques sont assemblées l'une à l'autre par des parties pliées autour d'une direction parallèle à une direction lonqitudinale des coques, et de préférence encore, les caissons sont articulés les uns par rapport aux autres par une imbrication des parties pliées.According to a preferred embodiment of the invention, each box comprises two shells assembled to each other. Preferably the hulls are assembled to one another by folded portions around a direction parallel to a longitudinal direction of the hulls, and more preferably, the boxes are hinged to each other by a nesting of the parts. folded.
BRÈVE DESCRIPTION DES DESSINS D'autres caractéristiques et avantaqes de l'invention apparaîtront encore à la lecture de la description qui suit d'un mode de réalisation préféré non limitatif de l'invention en référence à la figure unique ci-jointe qui est une vue en perspective schématique partielle d'un tablier de sécurité selon l'invention.BRIEF DESCRIPTION OF THE DRAWINGS Other features and advantages of the invention will become apparent upon reading the following description of a preferred non-limiting embodiment of the invention with reference to the attached single figure which is a view of the invention. in partial schematic perspective of a safety apron according to the invention.
DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION
En référence à la figure, le tablier de sécurité selon l'invention comporte une série d'éléments de sécurité 1 comprenant chacun un caisson allongé 2 formé de deux coques 3 assemblées l'une à l'autre par des parties de coque 4 s'étendant le long des bords longitudinaux des coques et pliées autour d'une direction parallèle à une direction longitudinale 7 des coques. Les caissons sont articulés les uns par rapport aux autres par une imbrication des parties pliées 4.Referring to the figure, the safety apron according to the invention comprises a series of safety elements 1 each comprising an elongated box 2 formed of two shells 3 joined to each other by shell portions 4 s' extending along the longitudinal edges of the hulls and folded around a direction parallel to a longitudinal direction 7 of the hulls. The boxes are hinged to each other by a nesting of the folded parts 4.
Chaque caisson à une section identique sur toute sa longueur et chaque caisson comprend à une extrémité une ouverture 5 ayant un contour identique à la section du caisson. Des blocs 6 ayant une section identique à la section des caissons peuvent ainsi être introduits à l'intérieur des caissons par simple coulissement. Les blocs 6 sont en fibre synthétique comprimée, de préférence en fibre d'aramide, de préférence encore en poly-paraphénylène téréphtalamide. Les blocs 6 sont réalisés avec un léger jeu par rapport aux ouvertures 5 de façon à permettre une introduction aisée des blocs 6 dans les caissons 2.Each box with an identical section over its entire length and each box comprises at one end an opening 5 having a contour identical to the section of the box. Blocks 6 having a section identical to the box section can thus be introduced inside the boxes by simple sliding. The blocks 6 are compressed synthetic fiber, preferably aramid fiber, more preferably poly-para-phenylene terephthalamide. The blocks 6 are made with a slight clearance with respect to the openings 5 so as to allow easy introduction of the blocks 6 into the boxes 2.
Bien entendu l'invention ne pas limitée au mode de réalisation décrit et est susceptible de variantes de réalisation dans le cadre de l'invention telle que définie par les revendications. En particulier, bien que l'invention ait été illustrée avec des blocs de fibres synthétiques 6 remplissant totalement les caissons 2, on peut réaliser l'invention en disposant dans les caissons 2 des barres de fibre synthétique comprimée espacées les unes des autres, ce qui permet de réaliser des caissons ayant une raideur importante tout en minimisant le coût.Naturally, the invention is not limited to the embodiment described and is capable of alternative embodiments within the scope of the invention as defined by the claims. In particular, although the invention has been illustrated with blocks of synthetic fibers 6 completely filling the boxes 2, it is possible to realize the invention by placing in the boxes 2 bars of compressed synthetic fiber spaced apart from each other, which makes it possible to produce boxes having a high stiffness while minimizing the cost.
Bien que l'invention ait été décrite en représentant seulement une partie du tablier, le tablier est porté de façon connue en soi dans un encadrement.Although the invention has been described by representing only a part of the deck, the deck is carried in a manner known per se in a frame.
