Description
L'invention concerne un dispositif de protection individuelle anti-bruitThe invention relates to a device for personal protection against noise
muni de moyens de communications.equipped with means of communication.
Généralement les dispositifs anti-bruit de communicationse présentent sous la forme d'un casque muni de deux coussins à absorption acoustique, destinés à être appliqués contre les oreilles. In general, the communication anti-noise devices are in the form of a helmet provided with two acoustic absorption cushions intended to be applied against the ears.
Dans des ateliers ou chantiers très bruyants les personnes travaillant ont l'obligation de se protéger contre le bruit et doivent donc porter ce type de casque. Le casque est souvent un casque intégral de manière à apporter une protection également contre des chutes d'objets lourds ou en cas de déflagration ou d'incendie et peut peser jusqu'à lkg. In very noisy workshops or work sites, working people have the obligation to protect themselves against noise and must therefore wear this type of helmet. The helmet is often an integral helmet so as to provide protection against falling heavy objects or in case of explosion or fire and can weigh up to 1kg.
Il existe des casques anti-bruit équipés de moyens de communications de manière à ce que les personnes puissent être alertées en cas de danger ou plus généralement communi- quer avec leur environnement sans avoir à retirer le casque. There are anti-noise helmets equipped with means of communication so that people can be alerted in case of danger or more generally communicate with their environment without having to remove the helmet.
A cette fin, les casques anti-bruit comportent sur une oreillette ou sur les deux, un écouteur relié à un système de communications au moyen d'un câble. Ils comportent également un microphone relié également à ce système de communication, placé devant la bouche de l'utilisateur ou dé-porté sur le côté, l'utilisateur devant alors le manipuler pour le ramener devant la bouche. Dans tous les cas le microphone capte les bruits ambiants. For this purpose, the earmuffs have on one earpiece or both, an earphone connected to a communications system by means of a cable. They also include a microphone also connected to this communication system, placed in front of the mouth of the user or dé-port on the side, the user must then manipulate to bring it in front of the mouth. In all cases the microphone picks up ambient noise.
Dans le cas de casques utilisés en milieu particulièrement hostiles, le câble est un câble spécifique antidéflagration. In the case of helmets used in particularly hostile environments, the cable is a specific explosion-proof cable.
0152-ACOUST01 2866191 2 Il est possible également pour une personne de communiquer à l'aide d'un ostéomicrophone fixé à l'intérieur du casque. Dans ce cas, l'ostéomicrophone est fixé de manière à être en contact avec le crâne de la personne pour pouvoir capter ses paroles. Ce dispositif est relié par un câble au système de radiocommunications. 0152-ACOUST01 2866191 2 It is also possible for a person to communicate using an osteomicrophone attached to the inside of the helmet. In this case, the osteomicrophone is fixed so as to be in contact with the skull of the person to be able to capture his words. This device is connected by a cable to the radio system.
Ces casques assurent une protection contre le bruit ambiant aux personnes sur un chantier et en même temps ils leur permettre des communications avec l'environnement sans avoir à retirer le casque. Ces casques permettent en parti- culier de recevoir des alertes en cas de danger. These helmets provide protection against ambient noise to people on a construction site and at the same time allow them to communicate with the environment without having to remove the helmet. These helmets make it possible to receive alerts in case of danger.
La plus part des casques anti-bruit munis de moyens de communications existants permettent de communiquer correctement en présence de bruits allant de 60 à 90dB. Most noise-canceling headphones equipped with existing communication means can communicate properly in the presence of noises ranging from 60 to 90dB.
En revanche, aucun casque anti-bruit muni de moyens de communications n'est efficace pour des bruits de niveau supérieur, pouvant atteindre 100 à 120dB. On the other hand, no noise-canceling headphones equipped with communication means is effective for higher level noise, up to 100 to 120dB.
En outre aucun casque n'est adapté à des conditions de travail difficiles, chaleur excessive: 40 C et plus; humidité de l'air ambiant; pollution de l'air (sel, pous- sières). In addition no helmet is suitable for difficult working conditions, excessive heat: 40 C and more; ambient humidity; air pollution (salt, dust).
En effet, les casques anti-bruit existants ne sont tolérés dans de telles conditions que s'ils sont portés pas plus de 2 à 3 heures car très vite les personnes éprouvent un inconfort qui les conduit à retirer le casque pour éponger la sudation et retirer les poussières collées sur leur visage. Indeed, the existing earmuffs are only tolerated in such conditions if they are worn no more than 2 to 3 hours because very quickly people experience discomfort that leads them to remove the helmet to mop sweat and remove the dust stuck on their faces.
De plus, les casques existants tombent en panne régulièrement du fait de ces conditions difficiles et retour- nent fréquemment au service après vente ce qui oblige à pré- 0152-A CO US TOI voir un parc de casques de remplacement et un coût de service après vente et de transport important. Moreover, the existing helmets regularly fail due to these difficult conditions and frequently return to the after-sales service which requires pre-0152-A CO US TO see a fleet of replacement helmets and a cost of service afterwards. sale and important transportation.
L'invention a pour but de remédier à ces problèmes. The object of the invention is to remedy these problems.
L'invention a pour objet un dispositif de protection individuelle antibruit comprenant des moyens de communication principalement caractérisé en ce qu'il comprend une fourche tubulaire, chaque branche de la fourche comprenant à son extrémité un embout auditif muni d'un bouchon antibruit, l'embout et le bouchon étant munis d'un canal qui communique avec le canal de la branche tubulaire sur la-quelle il est placé, ces canaux se rejoignant à la jonction des deux branches de la fourche, et en ce que cette jonction comporte une cellule microphone-écouteur non soumise aux bruits extérieurs. The invention relates to a personal noise protection device comprising communication means mainly characterized in that it comprises a tubular fork, each branch of the fork comprising at its end a hearing tip provided with a noise-reducing cap, the nozzle and cap being provided with a channel which communicates with the channel of the tubular branch on which it is placed, these channels joining at the junction of the two branches of the fork, and in that this junction comprises a cell microphone-earpiece not subject to external noise.
Selon une autre caractéristique, le dispositif comporte un tube souple raccordé à l'une des branches de la fourche et/ou à l'un des embouts auditifs pour guider la voix de la personne ainsi équipée. According to another characteristic, the device comprises a flexible tube connected to one of the branches of the fork and / or one of the hearing tips to guide the voice of the person thus equipped.
Selon une autre caractéristique, les bouchons sont dans un matériau absorbant acoustique ayant la forme exacte du conduit auditif externe de l'utilisateur, ces bouchons ayant été réalisés au moyen de l'empreinte dudit conduit auditif. According to another characteristic, the plugs are in an acoustic absorbent material having the exact shape of the user's external auditory canal, these plugs having been made by means of the impression of said auditory canal.
Avantageusement, le matériau dans lequel sont réali- sés les bouchons est un silicone souple ou thermo déformable ou acrylique ou un matériau compatible physiologiquement. Advantageously, the material in which the plugs are made is a flexible or thermo-deformable or acrylic silicone or a physiologically compatible material.
Selon une autre caractéristique, les embouts, les bouchons, le tube souple et la cellule microphone-écouteur sont des pièces amovibles de manière à pouvoir être changées aisément. According to another characteristic, the end pieces, the plugs, the flexible tube and the microphone-earpiece cell are removable parts so that they can be easily changed.
0152-A COUSTO 1 Selon une autre caractéristique, les branches de la fourche sont semi-rigides ou souples de manière à pouvoir les passer sous le menton ou derrière la nuque permettant une totale liberté de mouvement à l'utilisateur. 0152-A COUSTO 1 According to another feature, the branches of the fork are semi-rigid or flexible so as to pass under the chin or behind the neck allowing complete freedom of movement to the user.
Selon une autre caractéristique, la cellule microphone-écouteur comprend des moyens de connexion pour être relié à un système de radio communications. According to another characteristic, the microphone-earphone cell comprises connection means for connection to a radio communications system.
D'autres particularités et avantages de l'invention ap- paraîtront clairement à la lecture de la description qui est 10 faite ci- après et qui est donnée à titre d'exemple illustra- tif et non limitatif et en regard des figures sur lesquelles - la figure 1, un schéma général du dispositif selon l'invention, - la figure 2, une vue éclatée du dispositif. Other features and advantages of the invention will appear clearly on reading the description which is given below and which is given by way of illustrative and nonlimiting example and with reference to the figures in which - Figure 1, a general diagram of the device according to the invention - Figure 2, an exploded view of the device.
Le dispositif comporte une fourche tubulaire 1 qui peut avoir une forme en V de type stéthoscope ou en arceau. The device comprises a tubular fork 1 which may have a V-shaped stethoscope or arch.
Chaque branche 10, 11 de la fourche 1 est équipée à 20 son extrémité d'un embout auditif 12, 14 muni d'un bouchon anti-bruit 13, 15. Les embouts 12, 14 et les bouchons 13, 15 sont traversés par un canal respectivement 120, 130, et 140, 150 qui sont dans le prolongement l'un de l'autre et qui communiquent avec le canal 101 et respectivement 110 de la branche tubulaire sur laquelle ils sont placés. Each branch 10, 11 of the fork 1 is equipped at its end with a hearing tip 12, 14 provided with an anti-noise plug 13, 15. The tips 12, 14 and the plugs 13, 15 are traversed by a channel respectively 120, 130, and 140, 150 which are in the extension of one another and which communicate with the channel 101 and 110 respectively of the tubular branch on which they are placed.
Un logement 20 est prévu à la jonction des deux branches 10 et 11 de la fourche pour recevoir une cellule microphone-écouteur 30. Cette cellule 30 est dans une capsule lui conférant une étanchéité aux bruits extérieurs. A housing 20 is provided at the junction of the two branches 10 and 11 of the fork to receive a microphone-earpiece cell 30. This cell 30 is in a capsule giving it a seal against external noise.
Les canaux 101 et 110 débouchent dans ce logement de manière à ce que la cellule 30 soit en contact direct avec 0152-ACOUST01 2866191 5 ces canaux pour émettre les sons vers les canaux ou recevoir les sons des canaux. The channels 101 and 110 open into this slot so that the cell 30 is in direct contact with these channels to emit the sounds to the channels or to receive the sounds of the channels.
La cellule microphone-écouteur 30 est relié par un câble 40 au système de radio communications 50. The microphone-earphone cell 30 is connected by a cable 40 to the radio communications system 50.
Les bouchons 13, 15 sont en matériau absorbant acoustique. Ils sont de préférence réalisés dans un silicone souple ou thermo déformable ou en acrylique, anallergique et aisément déformable, telle une prothèse auditive. The plugs 13, 15 are of acoustic absorbing material. They are preferably made of a flexible or thermo-deformable silicone or acrylic, hypoallergenic and easily deformable, such as a hearing aid.
Un tube souple 60, de préférence à mémoire de forme, est raccordé à l'un des embouts auditifs ou à l'une des branches tubulaires du dispositif. Ce tube comporte en son extrémité une tuyère avec un embout en entonnoir 61 que l'utilisateur peut amener devant sa bouche. A flexible tube 60, preferably with shape memory, is connected to one of the earpieces or to one of the tubular branches of the device. This tube has at its end a nozzle with a funnel tip 61 that the user can bring in front of his mouth.
Lorsque le tube 60 est raccordé, il accède à un ca- nal de communication, au canal 140 sur les figures selon l'exemple, et permet de guider les paroles de l'utilisateur jusqu'à la cellule microphone-écouteur 30. When the tube 60 is connected, it accesses a communication channel, the channel 140 in the figures according to the example, and allows to guide the words of the user to the microphone-earpiece 30 cell.
Les messages ou alertes émis par le système de radio communications arrivent à la cellule microphone-écouteur 30 qui les diffuse dans chaque canal de communication jusque dans chacun des bouchons. Ainsi la personne qui porte le dispositif peut entendre des messages qui lui sont envoyés à partir du système radio communications sans entendre les bruits extérieurs. De la même façon lorsque la personne parle devant la tuyère 61, ces paroles arrivent à la cellule microphone-écouteur qui n'est pas soumise aux bruits extérieurs et qui ne transmet en conséquence que les paroles de la personne. The messages or alerts issued by the radio communications system arrive at the microphone-earphone cell 30 which broadcasts them in each communication channel into each of the plugs. Thus the person wearing the device can hear messages sent to him from the radio communications system without hearing external noises. In the same way when the person speaks in front of the nozzle 61, these words arrive at the microphone-earphone cell which is not subject to external noises and which transmits consequently only the words of the person.
Le dispositif est réalisé dans des matériaux légers 30 tels que du plastique, son poids est de l'ordre de 34 gram- mes et en tous cas inférieur à 85 grammes (non compris le 0152-ACOUST01 2866191 6 système de communications 50 associé), il est donc très léger par rapport aux systèmes existants qui pèsent environs 250 grammes. The device is made of lightweight materials such as plastic, its weight is of the order of 34 grams and in any case less than 85 grams (not including the associated communication system 50), it is therefore very light compared to existing systems which weigh about 250 grams.
Les bouchons absorbants 13, 15 sont de préférence en silicone souple anallergique ou en matériaux compatibles physiologiquement et aisément désinfectables. Absorbent plugs 13, 15 are preferably made of non-allergenic soft silicone or physiologically compatible and easily disinfectable materials.
En outre de manière à faciliter l'entretient du dis-positif, les différentes pièces le constituant sont conçues de manière à être séparables les unes des autres et à pou- voir être ainsi remplacées en cas de défectuosité. Furthermore, in order to facilitate maintenance of the dis-positive, the various parts constituting it are designed so as to be separable from each other and can thus be replaced in the event of a defect.
Ainsi, la fourche est munie d'une pièce de jonction 16, des tubes 10 et 11, des embouts auditifs 12 et 14, des bouchons 13 et 15 et de la cellule microphone -écouteur 30. Thus, the fork is provided with a connecting piece 16, tubes 10 and 11, hearing tips 12 and 14, plugs 13 and 15 and microphone-earpiece 30.
Les tubes 10 et 11 se raccordent d'une part à la pièce de jonction 16 et d'autre part aux embouts 12 et 14. Les bouchons 13 et 15 s'emboîtent aux embouts 12 et 14 et la cellule 30 s'emboîte dans le logement 20. The tubes 10 and 11 are connected on the one hand to the connecting piece 16 and on the other hand to the end pieces 12 and 14. The plugs 13 and 15 fit into the end pieces 12 and 14 and the cell 30 fits into the housing 20.
Le dispositif qui vient d'être décrit est particulièrement adapté pour des utilisations dans des ateliers ou plate-forme pétrolière dans un environnement très bruyant plus de 100dB, très chaud plus de 40 C, très humide et poussiéreux sans inconfort pour les utilisateurs et en assurant parfaitement les fonctions anti-bruit et communications. The device that has just been described is particularly suitable for uses in workshops or oil platform in a very noisy environment over 100dB, very hot over 40 C, very wet and dusty without discomfort for users and ensuring perfectly anti-noise and communications functions.
