Abstract

The device functions in the following manner: the duct 1 provided with a filter 3 is equipped with a motor 2 adapted for a current of 220V which propels the air as far as the duct 4, this air emerges with power via the cells 5 placed all along this duct 4 (section along AA) in the vertical direction towards the duct 7 (section along BB) which is placed at the bottom and is of a flared shape in order better to receive this air. This duct 7 is equipped with a motor 9, which has the function of drawing in the air propelled by the duct 4, and has an outlet filter 8. The device according to the invention is intended in particular to equip motor cars between driver and passengers, counter windows, offices (blowing and sucking ducts), displays of food products and cradles (sucking ducts only).

Description

La présente invention concerne un dispositif permettant de réduire la pénétration des fumées, poussières et insectes volants dans une surface bien définie. The present invention relates to a device making it possible to reduce the penetration of smoke, dust and flying insects into a well-defined surface.

Certaines personnes étant allergiques à la fumée pourront ainsi être protégées par ce dispositif en presque totalité. I1 sera également utilisé sous une forme pour protéger un étalage de denrées alimentaire ou un berceau. Some people who are allergic to smoke can thus be protected by this device in almost all. It will also be used in a form to protect a food display or a cradle.

Cc dispositif selon l'invention est caractérisé en ce qu'il comprcnd un ou plusieurs cadres de gaines emboitables (soufflantes et aspirantes). Cc device according to the invention is characterized in that it comprcnd one or more frames of nestable sheaths (blowers and suction).

L'ensemble pour le plus simple est représenté par un cadre FIG 1 de gaines emboitables en matériau léger tel que le plastique ou l'aluminium. The assembly for the simplest is represented by a frame FIG 1 of nestable sheaths in light material such as plastic or aluminum.

Le dispositif fonctionne de la façon suivante : la gaine (1) munit d'un filtre (3) est équipée d'un moteur (2) adapté au courant 220 V qui propulse l'air jusqu'à la gaine (4), cet air ressort avec puissance par les alvéoles (5) placées tout le long de la gaine (4) (coupe suivant AA) en direction verticale vers la gaine (7) (coupe suivant BB) placée en bas et qui est de forme évasée afin de mieux réceptionner cet air. Cette gaine (7) est équipée d'un moteur (9) qui a pour fonction d'aspirer l'air propulsé par la gaine (4), elle possède un filtre (8) en sortie. The device operates as follows: the sheath (1) provided with a filter (3) is equipped with a motor (2) adapted to the 220 V current which propels the air to the sheath (4), this air comes out powerfully through the cells (5) placed all along the sheath (4) (cut along AA) in a vertical direction towards the sheath (7) (cut along BB) placed at the bottom and which is flared in order to better receive this air. This sheath (7) is equipped with a motor (9) which has the function of sucking the air propelled by the sheath (4), it has a filter (8) at the outlet.

Un seul branchement suffit à faire fonctionner les deux moteurs, les gaines (4 et 7) sont maintenues par un support (6). A single connection is sufficient to operate the two motors, the ducts (4 and 7) are held by a support (6).

Le dispositif selon l'invention (propulsion - aspiration) forme un écran d'air caractérisé en ce que la fumée ne passe pas et est absorbée en presque totalité, protégeant ainsi la ou les personnes placées derrière cet écran. The device according to the invention (propulsion - aspiration) forms an air screen characterized in that the smoke does not pass and is absorbed almost entirely, thus protecting the person or persons placed behind this screen.

Le dispositif selon la description ci-dessus peut prendre différentes fonnes de montage, l'ensemble étant composé de gaines emboitables, exemple : pour un guichet ou un bureau on pourra monter un écran principal et un écran de chaque côté FIG 2, l'avantage du procédé permet à une personne placée derrière un guichet ou un bureau de passer un document ou un objet à la personne lui faisant face tout en restant protégée par les écrans à air continu. The device according to the description above can take different mounting forms, the assembly being composed of nestable sheaths, for example: for a counter or an office, it is possible to mount a main screen and a screen on each side FIG 2, the advantage of the method allows a person behind a counter or a desk to pass a document or an object to the person facing him while remaining protected by continuous air screens.

Le dispositif peut également être utilisé pour les étalages de denrées alimentaire avec les gaines soufflantes uniquement (FIG 3 vu de dessus FIG 4 vu de côté) il suffit pour se faire de placer les gaines sur le bord de l'étalage, qu'il soit de forme carré ou rectangulaire. Les gaines (1) le composant seront maintenues par trois supports coudés (2), l'air propulsé par un moteur (3) munit d'un filtre (5) sera orienté de façon à se croiSer en faisceaux aux points A et B formant ainsi un écran protecteur contre les fumées, poussières et insectes volants. l'étalage ainsi équipé est protégé en presaue totalité. The device can also be used for food displays with blowing ducts only (FIG 3 seen from above FIG 4 seen from the side) it is sufficient to place the ducts on the edge of the display, whether it is square or rectangular. The sheaths (1) the component will be maintained by three bent supports (2), the air propelled by a motor (3) provided with a filter (5) will be oriented so as to cross in bundles at points A and B forming thus a protective screen against fumes, dust and flying insects. the display thus equipped is almost entirely protected.

Le dispositif cidessus est caractérisé -n ce que le moteur (3) est équipé d'un variateur de puissance (4) qui pellet de régler le débit de l'air, en fonction de la densité des fumées, poussières et insectes volants
Ce dispositif est prévu pour protéger un étalage de denrées alimentaire ou un berceau.The above device is characterized -n that the motor (3) is equipped with a power variator (4) which shovels to regulate the air flow, as a function of the density of smoke, dust and flying insects
This device is intended to protect a display of foodstuffs or a cradle.

Dans une voiture, l'écran sera placé entre le chauffeur et les passagers. L'air vicié sortira par un conduit débouchant en dessous du véhicule, le dispositif sera identique à celui présenté FIG 1. L'ensemble fonctionnera sur l'allume cigare, il est bien évident que le dispositif ne sera performant que si les vitres du véhicule sont fermées.  In a car, the screen will be placed between the driver and the passengers. The stale air will come out through a conduit opening below the vehicle, the device will be identical to that shown in FIG 1. The assembly will operate on the cigarette lighter, it is quite obvious that the device will only be effective if the vehicle windows are closed.
