Description

La présente invention concerne un dispositif destiné à découper un trou carré, rectangulaire, rond, ovale dans une plaque de matériau ou de panneau permettant l'encastrement d'objet. La découpe de trou est traditionnellement effectuée à la main au moyen d'une scie dentée type égoïne ou électrique, à l'utilisation il y a un risque de couper des canalisations électriques et autres tuyaux non visibles dans le vide de construction, pouvant provoquer des chocs électriques et autres blessures pour l'utilisateur, ainsi que des coupes incorrectes et irrégulières, et une perte de temps notable à l'exécution. Le dispositif selon l'invention permet de réaliser automatiquement la découpe de trous carrés, rectangulaires, ronds, ovales à la perfection sans laisser de bavure et d'une utilisation très facile dans faux plafonds, parois murales et tous matériaux de construction. Le dispositif à ce stade ne nécessite pas d'énergie mais il pourrait être actionné par un outillage électrique ou pneumatique. Le dispositif de l'invention dénommé, matrice à découper, fonctionne avec une simple pince à cliquet, en exerçant une pression sur la pince on écarte le piston du support conique permettant sans effort la pénétration des lames dans le matériau à découper et d'obtenir une découpe franche nette et précise. Le dispositif peut être utilisé dans des parois au plafond et au sol en toutes positions permettant ainsi l'encastrement de luminaires, spots, boîtiers et tout autre objet 20 encastrable de sections carrées, rectangulaires, rondes, ovales de différentes dimensions, d'épaisseur et de diamètre. Le dispositif pourra être utilisé sur des chantiers de construction non alimenté en électricité, c'est-à-dire de façon autonome. Réalisant ainsi une réelle économie d'énergie. 25 Les dessins annexés illustrent l'invention, en référence à ces dessins, le dispositif comporte deux éléments, un support conique (7) pourvu d'un évidement cylindrique (8) en son centre et un piston (3a) se logeant dans l'évidement (8) du support conique(7), le support conique (7), comprend sur sa partie supérieure une platine support de lame (4) ayant des rainures de différentes formes géométriques (5) sur 30 laquelle un élément élastique par exemple un ressort (3) soudé sur la platine (4) et une rondelle (2) faisant corps avec le système élastique (3) dans sa partie supérieure. Le support conique (7), comprend aussi dans sa partie inférieure un écrou de fermeture (9) démontable pourvu d'une ouverture permettant la pénétration du piston (3a) dans l'évidement cylindrique (8) du support (7). En position de travail Le piston (3a) comporte à son extrémité, d'une tête foreuse (1a) sur laquelle se situent latéralement au moins deux ailettes (2a) basculantes qui viennent en appui sur le matériau (1) qui se trouve pris en étau avec la rondelle (2). Une gorge (6a) permet de loger les ailettes (2a) au repos, le pied du piston comporte un talon (4a) et une encoche (5a), destinée à recevoir un outil, par exemple un tourne vis, (figure n° 2). Dans la forme de la réalisation selon la figure 1, la matrice à découper comprend une platine (4) munie de rainures (5), de lames de découpe (6), un ressort (3) permettant 10 de maintenir à plat le matériau (1) sur la rondelle (2) Le piston (3a) pénètre le matériau (1) par pression sur la pince à cliquet, lorsque la tête de foret (1a) arrive dans le vide, les ailettes (2a) basculent et se placent à l'horizontale sur le matériau (1) pinçant ainsi le matériau (1) entre les ailettes (2a) et la rondelle (2), le matériau étant prêt à être découpé par les lames (6), en écartant avec 15 une pince à cliquet, le piston (3a) du support conique (7). A titre d'exemple, la matrice de découpe pourra avoir des dimensions différentes, selon le besoin de la découpe à réaliser pouvant aller de 6cm à 60cm, permettant ainsi l'encastrement de tout objet de forme et de taille différente. Le dispositif selon l'invention est particulièrement destiné à découper des trous carrés, 20 rectangulaires, ronds, ovales dans tout matériau et panneau selon le besoin et en toute sécurité pour l'utilisateur. Le dispositif selon l'invention est particulièrement destiné à découper des trous de réservation dans les faux plafonds et parois de construction pour l'encastrement de tout objet tels que luminaires, spots, boîtiers, grilles de ventilation, appareillages 25 électriques, cadres métalliques, et toutes pièces carrées, rectangulaires, rondes, ovales. Le piston (3a) est pourvu d'un épaulement qui lui permet de venir en butée sur l'écrou (9). La platine (4) est pourvue de pointeurs de cadrage, (10) disposés sur les quatre côtés de la platine. The present invention relates to a device for cutting a square, rectangular, round, oval hole in a plate of material or panel for embedding object. Hole cutting is traditionally done by hand using a saw saw type handsaw or electric, the use there is a risk of cutting electrical pipes and other pipes not visible in the building vacuum, which can cause electric shocks and other injuries to the user, as well as incorrect and irregular cuts, and a significant loss of execution time. The device according to the invention makes it possible to automatically cut square, rectangular, round, oval holes to perfection without leaving any burrs and very easy to use in false ceilings, walls and all building materials. The device at this stage does not require energy but it could be operated by an electrical or pneumatic tool. The device of the invention called die to cut, operates with a simple ratchet, exerting pressure on the clamp is moved away from the piston conical support allowing effortless penetration of the blades in the material to be cut and obtain clean and precise cut. The device can be used in walls on the ceiling and on the floor in any position thus allowing the installation of luminaires, spotlights, housings and any other insertable object of square, rectangular, round, oval sections of different dimensions, thickness and of diameter. The device can be used on building sites that are not supplied with electricity, that is to say independently. Realizing a real saving of energy. The accompanying drawings illustrate the invention, with reference to these drawings, the device comprises two elements, a conical support (7) provided with a cylindrical recess (8) at its center and a piston (3a) housed in the recess (8) of the conical support (7), the conical support (7) comprises on its upper part a blade support plate (4) having grooves of different geometrical shapes (5) on which an elastic element for example a spring (3) welded to the plate (4) and a washer (2) integral with the elastic system (3) in its upper part. The conical support (7), also comprises in its lower part a removable locking nut (9) provided with an opening for the penetration of the piston (3a) into the cylindrical recess (8) of the support (7). In working position The piston (3a) has at its end, a drilling head (1a) on which are located laterally at least two flanges (2a) which bear against the material (1) which is taken into account. vice with the washer (2). A groove (6a) makes it possible to house the fins (2a) at rest, the foot of the piston comprises a heel (4a) and a notch (5a) intended to receive a tool, for example a screwdriver, (FIG. ). In the form of the embodiment according to FIG. 1, the die to be cut comprises a plate (4) provided with grooves (5), cutting blades (6), a spring (3) allowing the material to be held flat ( 1) on the washer (2) The piston (3a) penetrates the material (1) by pressing on the ratchet, when the drill head (1a) arrives in the vacuum, the fins (2a) tilt and move to the horizontal on the material (1) thus pinching the material (1) between the fins (2a) and the washer (2), the material being ready to be cut by the blades (6), moving away with ratchet, the piston (3a) of the conical support (7). For example, the cutting die may have different dimensions, depending on the need of the cut to achieve from 6cm to 60cm, allowing the embedding of any object of different shape and size. The device according to the invention is particularly intended for cutting square, rectangular, round, oval holes in any material and panel as required and in complete safety for the user. The device according to the invention is particularly intended for cutting reservation holes in the false ceilings and building walls for embedding any object such as luminaires, spotlights, housings, ventilation grilles, electrical equipment, metal frames, and all square, rectangular, round, oval pieces. The piston (3a) is provided with a shoulder which allows it to abut on the nut (9). The plate (4) is provided with framing pointers (10) arranged on the four sides of the plate.
