Abstract

Device making all pneumatic appliances (staplers, screwing machines, pneumatic drills, etc) autonomous. The subject of the invention is a device which provides the energy necessary for the functioning of the pneumatic tool, giving it a certain autonomy of operation whilst being perfectly autonomous, free of any flex. Referring to the figure, I is the tank in which a gas is stored under a certain pressure. The flow rate limiter 2 releases the quantity and pressure of gas necessary for the correct operation of the tool in order to give it autonomy and correct operation. The refill valve 3 makes it possible to refill the reservoir I in a few seconds, with the aid of a special high-pressure compressor. This type of invention can be used wherever the cable hinders movement and freedom of action.

Description

La présente invention a pour objet à titre de produit industriel nouveau , un dispositif rendant autonome tous les appareils pneumatique (agrafeuses , visseuses , perceuses pneumatique , etc
Actuellement , les outils pneumatiques sont reliés à un compresseur de taille variable via un cable qui rend le déplacement avec ces outils plus ou moins difficile. De plus ces cables ont une facheuse tendance à se vrier , se nouer ou meme s'accrocher entre eux si on en utilise plusieurs
(photo I).Le rayon d'action de ces outils est limité à la longueur du cable qui ne peut Aetre très importante si on ne veut pas accentuer les défauts cités-ci dessus .Sans parler de certains objets (machines importantes , tables de travail chaises, etc...) qui constituent de véritables chicanes et qui empèchele libre déplacement de l'utilisateur , qui doit sans cesse penser à son cable afin de ne pas se trouver bloqué avec une longueur de cable insufîsante.(photo 2 et 3)
Sans oublier que si l'utilisateur se sert de plusieurs outils à la fois (ce qui est très fréquent ) , il doit sans cesse les raccorder au mêtne cable , vu que le nombre de cables est généralement limité à deux par travailleur (photo 4)
Il ne faut pas oublier que l'on risque de trébucher sur les cables qui trainent par terre (photo 5) , et lorsque il faut les démêler , cela constitue un véritable casse tete (photo I)o Tbut cele cause une perte de temps et d'énergie humaine d'ou une baisse de rendement que nous pourrions éviter grace à ce système.The present invention relates to, as a new industrial product, a device making all pneumatic devices autonomous (staplers, screwdrivers, pneumatic drills, etc.
Currently, pneumatic tools are connected to a compressor of variable size via a cable which makes movement with these tools more or less difficult. In addition, these cables have a tendency to twist, tie or even hang between them if you use several
(photo I). The radius of action of these tools is limited to the length of the cable which cannot be very important if one does not want to accentuate the faults mentioned above. Not to mention certain objects (important machines, tables of working chairs, etc ...) which constitute real baffles and which prevents the free movement of the user, who must constantly think of his cable so as not to be blocked with an insufficient length of cable. (photo 2 and 3 )
Without forgetting that if the user uses several tools at the same time (which is very frequent), he must constantly connect them to the same cable, since the number of cables is generally limited to two per worker (photo 4)
It should not be forgotten that there is a risk of tripping over the cables lying around on the ground (photo 5), and when it is necessary to untangle them, this constitutes a real headache (photo I) o Tbut this causes waste of time and of human energy or a drop in yield that we could avoid thanks to this system.

Cependant ,il existe sur le marché des appareils autonomes mais fonctionnent à l'aide d'une batterie électrique incorporée qui présente plusieurs défauts :
la recharge de la batterie dure plusieurs heures alors
que notre invention se recharge en quelques secondes
- les outils électriques ne peuvent en aucun cas concuren
cer un outil pneumatique dans sa qualité et sa disponibi
lité pour un travail soigné (exemple type : agrafeuse )
- ce type d'outil est très peu répendu en comparaison des
outils pneumatique que l'on trouve partout
En effet , toutes les usines , les artisans, et de plus en plus de particuliers utilisent l'air comprimé au détriment des appareils electrique ell sont donc déja en possession de ces outils pneumatique et n'ont donc pas besoin de changer leurs outils , pouvent ainsi s'équiper de ce nouveau système à un prix très compétitif e
Le dispositif , objet de la présente invention permet d'assurer a la machine pneumatique une certaine autonomie de fonctionnement dans le temps tout en etant parfaitement autonome , libre de tout cordon e Cette invention trouvera sa place dans toutes les entreprises utilisant des appareils pneumatique mais aussi bien sur chez les particuliers
Une forme d'execution de l'invention est décrite ci-après à titre indicatif et nullement limitatif en se réferent aux dessins annexes e
La figure I est une vue de l'invention montée directement sur l'outil e Le dispositif comporte tout dabord un réservoir (I) plus ou moins compacte ou est emmagasiné une certaine quantité de gaz sous pression . Un limiteur de débit t2) fixé au réservoir libère la quantité et la pression de gaz nécessaire au bon fonctionnement de l'outil lui assurant une autonomie correcte.Le principe du limiteur étant connu il est inutile de le décrire
Le limiteur est fixé directement ou avec un adaptateur sur l'arrivé d'air de l'outil suivant le mode de fixation spécifique à l'outil De part sa conception , notre invention s'adapte à n'importe quel outil pneumatique éxistant ou allant arriver sur le marché
Notre invention peu etre proposé en plusieurs versions dont voici les trois principales
- une version non rechargeable (jetable ) , surtout
pour les particuliers
-une version vendu avec consigne rechargeable à l'usine
ou chez un dépositaire muni d'un compresseur spécial
(à haute pression)
- une versionirechargeable directement chez l'utilisa
teur si celui veut bien s'équiper d'un compresseur prévu
cet effet (compresgseur a haute pression) dtautres solutions sont naturellement envisageable
Dans le cas du système rechargeable , notre invention sera munie d'une prise spéciale étanche(3) adaptable sur le compres- seur . On pourra donc recharger le réservoir (I) en quelques secondes.La prise à haute pression étant connue , il est inutile de la décrire
Il est bien entendu que la présente invention n'est pas limitée au mode de réalisation décrit et représenté qui constitue seulement un exemple auquel de nombreuses modifications peuvent êtres apportées sans que l'on s'écarte de la présente invention.However, there are autonomous devices on the market but operate using an incorporated electric battery which has several faults:
recharging the battery takes several hours so
that our invention recharges in seconds
- power tools cannot in any case compete
a pneumatic tool in its quality and availability
bed for careful work (typical example: stapler)
- this type of tool is very little used compared to
pneumatic tools found everywhere
Indeed, all factories, artisans, and more and more individuals use compressed air to the detriment of electric devices. They are therefore already in possession of these pneumatic tools and therefore do not need to change their tools, can to equip this new system at a very competitive price e
The device which is the subject of the present invention makes it possible to assure the pneumatic machine a certain operating autonomy over time while being perfectly autonomous, free of any cord. This invention will find its place in all companies using pneumatic devices but also of course in private homes
An embodiment of the invention is described below for information and is in no way limiting with reference to the accompanying drawings and
Figure I is a view of the invention mounted directly on the tool e The device firstly comprises a tank (I) more or less compact or is stored a certain amount of gas under pressure. A flow limiter t2) fixed to the tank releases the quantity and the pressure of gas necessary for the proper functioning of the tool ensuring a correct autonomy. The principle of the limiter being known, it is unnecessary to describe it
The limiter is fixed directly or with an adapter on the air inlet of the tool according to the specific fixing method for the tool. Due to its design, our invention adapts to any existing or going pneumatic tool arrive on the market
Our invention can be offered in several versions, here are the three main ones
- a non-rechargeable (disposable) version, especially
for individuals
-a version sold with refillable deposit at the factory
or at a dealer with a special compressor
(at high pressure)
- a version that can be recharged directly from the user
tor if he wants to equip himself with a compressor
this effect (high pressure compressor) other solutions are naturally possible
In the case of the rechargeable system, our invention will be provided with a special waterproof plug (3) adaptable to the compressor. It will therefore be possible to recharge the tank (I) in a few seconds. Since the high pressure outlet is known, it is unnecessary to describe it
It is understood that the present invention is not limited to the embodiment described and shown which is only an example to which many modifications can be made without departing from the present invention.

Ce type d'invention pourri servir partout ou il est difficile de se déplacer avec un cable ( pose des tentures metirrs du batiment , chaines de montage , ete *0), bref partout ou le cable occasionne une gène pour le déplacement et pour la liberté d'action This type of invention can be used wherever it is difficult to move around with a cable (installation of wall hangings in the building, assembly lines, summer * 0), in short wherever the cable causes discomfort for movement and freedom. action
