Abstract
Description
<B>GUIDE DE</B> PERÇAGE SOLIDAIRE<B>DU MANDRIN D'UNE PERCEUSE</B> La présente invention a pour objet un dispositif permettant de guider façon simple et précise le perçage, par une perceuse courante, d'un trou dans un mur, un plancher ou toute surface perpendiculaire<B>à</B> la mèche de perçage. The present invention relates to a device for guiding a simple and precise way drilling, by a common drill, a hole in a wall, floor or any perpendicular surface <B> to </ B> the drill bit.
On sait que si le perçage ne se fait pas perpendiculairement au plan<B>à</B> percer, les chevilles et vis qui seront ensuite placées, ne seront pas perpendiculaires<B>à</B> ce plan, ce pourra poser des problèmes de montage ou simplement d'esthétique. We know that if the drilling is not perpendicular to the plane <B> to </ B> drill, the dowels and screws that will be placed, will not be perpendicular <B> to </ B> this plan, it may pose mounting problems or simply aesthetics.
Dans l'art antérieur, des solutions ont été recherchées et décrites dans un certain nombre de brevets. En<B>77,</B> dans le brevet<B>2399297,</B> deux manchons coulissent dans l'autre<B>:</B> le manchon extérieur étant fixé sur la perceuse avec une vis, le second manchon glissant<B>à</B> l'intérieur en coopération avec un ressort. En<B>97,</B> le brevet<B>2768073</B> décrit deux blocs parallèles reliés par trois tiges<B>de</B> guidage perpendiculaires, ce qui permet, certes une grande précision de perçage, mais donne un dispositif encombrant. En<B>98,</B> c'est canon de guidage disque en contact avec la surface<B>à</B> percer, qui est décrit dans le brevet EP <B>0</B> 894<B>560 A 1.</B> In the prior art, solutions have been sought and described in a number of patents. In <B> 77, </ B> in patent <B> 2399297, </ B> two sleeves slide in the other <B>: </ B> the outer sleeve being fixed on the drill with a screw, the second sliding sleeve <B> to </ B> the inside in cooperation with a spring. In <B> 97, <B> 2768073 </ B> describes two parallel blocks connected by three perpendicular <B> guidance rods, which allows, of course, great drilling accuracy, but gives a bulky device. In <B> 98, </ B> it is guide barrel disk in contact with the drilling <B> surface, which is described in EP <B> 0 </ B> 894 <B > 560 A 1. </ B>
La présente invention regroupe tous les avantages obtenus par les dispositifs cités ci- dessus, c'est-à-dire<B>:</B> <B>1.</B> Percer perpendiculairement au plan de travail. 2. Voir en permanence la mèche durant le perçage. <B>3.</B> Permettre le réalage de la profondeur des trous. ZD Zn 4. Eviter le dérapage sur les matériaux glissants. The present invention combines all the advantages obtained by the devices mentioned above, that is to say <B>: <B> 1. </ B> Drill perpendicularly to the work plane. 2. Always see the wick during drilling. <B> 3. </ B> Allow the hole depth to be realigned. ZD Zn 4. Avoid skidding on slippery materials.
<B>5.</B> Eviter la dégradation du support, tant par le dispositif lui-même que par le mandrin en<B>f</B>in de course de la mèche. <B> 5. </ B> Avoid the degradation of the support, both by the device itself and by the mandrel in <B> f </ B> in stroke of the wick.
<B>6.</B> Circonscrire l'émission de poussière<B>à</B> l'intérieur du dispositif durant le perçage, et cela avec un faible encombrement et une mise en #uvre simple et rapide. <B> 6. </ B> Circumscribe the dust emission <B> to </ B> inside the device during drilling, and this with a small footprint and a simple and fast implementation.
La présente invention se compose d'un roulement<B>à</B> billes<B>(1),</B> serti dans un manchon cylindrique (2), l'embout distal du présent manchon cylindrique arrivant, lors du montage, au ras de l'embout du mandrin<B>(7).</B> Autour de ce premier manchon cylindrique (2), viennent en coulissement télescopique, selon les dimensions des mèches de perçage, ou<B>3</B> manchons cylindriques télescopiques supplémentaires<B>(3).</B> La course de ces différents manchons, l'un par rapport l'autre, est limitée (PI.2/2) par une couronne supéro-externe (4) pour le manchon intérieur et inféro-interne <B>(5)</B> pour le manchon extérieur. L'embout externe du manchon cylindrique le plus large est recouvert d'un jonc circulaire de gomme ( pour pallier les risques de dérapage. Tous les manchons cylindriques coulissants sont en matière plastique moulée transparente, ce qui permet de visualiser, en permanence, la progression de la mèche pendant le perçage. Sur toute la longueur des manchons cylindriques coulissants une règle millimétrée<B>(6)</B> longitudinale, aménagée de perforations<B>(11)</B> est imprimée ou moulée avec chaque manchon. Cet aménagement de règles imprimées disposées dans le prolongement les unes autres sur les différents cylindres, permet le réglage de la profondeur des trous par l'introduction d'une aoupille de butée (12) dans la perforation utile. Ces sont toutes de même dimension et séparées Ion gitudinalement les unes des autres par une distance qui se situe entre <B>1</B> et millimètres, selon les cas. The present invention consists of a ball bearing <B> to </ B> <B> (1), </ B> crimped in a cylindrical sleeve (2), the distal tip of the present cylindrical sleeve arriving, at the mounting, flush with the tip of the mandrel <B> (7). </ B> Around this first cylindrical sleeve (2), come in telescopic sliding, according to the dimensions of the drill bits, or <B> 3 < / B> additional telescopic cylindrical sleeves <B> (3). </ B> The stroke of these different sleeves, relative to each other, is limited (PI.2 / 2) by a super-external crown ( 4) for the inner and lower inner sleeve <B> (5) </ B> for the outer sleeve. The outer end of the widest cylindrical sleeve is covered by a circular ring of rubber (to alleviate the risk of slippage.) All cylindrical sliding sleeves are made of transparent molded plastic, which allows to visualize, constantly, the progression of the drill bit during drilling The lengthwise length of the sliding cylindrical sleeves is a millimetric <B> (6) </ B> longitudinal gauge, with perforations <B> (11) </ B>, printed or molded with each sleeve This arrangement of printed rules arranged in the extension of one another on the various cylinders, allows the adjustment of the depth of the holes by the introduction of an abutment pin (12) in the useful perforation.These are all the same size and separated longitudinally from each other by a distance between <B> 1 </ B> and millimeters, as the case may be.
Ainsi décrit, le présent dispositif se fixe en couronne, et préférentiellement en force, soit sur Vecrou généralement six pans<B>(8)</B> situé en avant du mandrin lorsque la perceuse en comporte un, soit sur le mandrin<B>(7)</B> lui-même. Seul le roulement<B>à</B> billes<B>(1)</B> est alors en contact, par sa couronne interne, avec le mandrin de la perceuse, ce qui permet l'immobilité totale manchons télescopiques, alors même que le mandrin<B>(7)</B> est en rotation. Thus described, the present device is fixed in a ring, and preferably in force, either on Vecrou generally hexagonal <B> (8) </ B> located in front of the mandrel when the drill has one, or on the mandrel <B > (7) </ B> himself. Only the bearing <B> to </ B> balls <B> (1) </ B> is then in contact, by its inner ring, with the chuck of the drill, which allows the total immobility telescopic sleeves, then same as the mandrel <B> (7) </ B> is rotating.
Dans le cas spécifique où le roulement<B>à</B> billes est placé sur l'écrou généralement<B>6</B> pans <B>(8)</B> lorsqu'il existe, le manchon cylindrique (2), dans lequel il est serti par sa couronne extérieure afin de pouvoir servir de guide fixe et de support aux autres manchons cylindriques coulissants, reste concentrique et externe au mandrin, lequel est généralement cylindrique. In the specific case where the bearing <B> to </ B> ball is placed on the nut usually <B> 6 </ B> sections <B> (8) </ B> where it exists, the cylindrical sleeve (2), in which it is crimped by its outer ring so as to serve as a fixed guide and support to the other sliding cylindrical sleeves, remains concentric and external to the mandrel, which is generally cylindrical.
Les différents manchons cylindriques (2 et<B>3)</B> du présent dispositif coulissent entre eux en constituant un ensemble tubulaire rigide, afin que, lorsque le dispositif est appliqué sur la surface<B>à</B> percer, les manchons cylindriques restent complètementen ligne pendant la durée<B>du</B> perçage, la mèche étant alors maintenue perpendiculaire<B>à</B> la surface<B>à</B> percer, ce qui le premier but recherché de l'invention. The various cylindrical sleeves (2 and <B> 3) </ B> of the present device slide between them forming a rigid tubular assembly, so that when the device is applied to the surface <B> to </ B> drill, the cylindrical sleeves remain completely in line during the drilling <B> duration, the drill bit then being held perpendicular <B> to the <B> surface to </ B> drill, which the first goal sought for the invention.
Lorsque tous les manchons télescopiques sont complètement emboîtés, leur limite distale arrive au ras de l'embout du mandrin, découvrant ainsi entièrement la partie active la mèche, tandis que leur limite proximale est en butée sur la couronne<B>(9)</B> du manchon cylindrique (2). When all the telescopic sleeves are completely nested, their distal limit is flush with the tip of the mandrel, thus fully discovering the part activates the wick, while their proximal limit is in abutment on the crown <B> (9) </ B> of the cylindrical sleeve (2).
Tous les manchons cylindriques coulissants<B>(3)</B> sont préférentiellement de meme hauteur, et cette hauteur est préférentiellement celle de la longueur du mandrin. All sliding cylindrical sleeves <B> (3) </ B> are preferably of the same height, and this height is preferably that of the length of the mandrel.
