COUTEAU D'EBARBAGE A FROID DES BORDS DE LA
PERIPHERIE DE PARE-BRISES
La présente invention a trait à un outil spécialement conçu pour l'ébarbage à froid des bords de la périphérie de pare-brises.COLD TRIMMING KNIFE
WINDSHIELD PERIPHERY
The present invention relates to a tool specially designed for cold deburring of the edges of the periphery of windshields.
Les bords des pare-brises, avant leur montage sur des véhicules, doivent être ébarbés et, à cet effet, on utilise généralement un couteau ou cutter qui n'est pas spécifiquement destiné à cet effet et ne présente donc pas toutes les garanties nécessaires, tout particulièrement la sécurité des manipulateurs qui, ce qui malheureusement n'est pas rare, se coupent ou se blessent, quelquefois gravement, lorsque, par exemple, leur outil dérape et vient en contact avec l'autre main du manipulateur chargée de tenir convenablement le parebrise en cours d'ébarbage. The edges of windshields, before mounting on vehicles, must be trimmed and, for this purpose, a knife or cutter is generally used which is not specifically intended for this purpose and therefore does not have all the necessary guarantees, especially the safety of the manipulators who, which unfortunately is not uncommon, cut or injure themselves, sometimes seriously, when, for example, their tool slips and comes into contact with the other hand of the manipulator responsible for keeping the windshield being deburred.
La présente invention vise précisément à palier ces graves inconvénients en proposant un outil adapté à ce type de travail et présentant toute sécurité pour son manipulateur. The present invention aims precisely to overcome these serious drawbacks by proposing a tool suitable for this type of work and having complete safety for its manipulator.
A cet effet, l'invention a pour objet un couteau d'ébarbage à froid des bords de la périphérie de pare-brise, caractérisé en ce qu'il est constitué d'une lame plane mince, d'un porte-lame dans lequel est enchâssée ladite lame et d'un manche solidaire du porte-lame, prolongeant celui-ci et dont l'axe est sensiblement parallèle au fil de la lame, ledit porte-lame étant configuré en forme de tête de clé plate à fourche de serrage d'écrou, au fond de l'ouverture de laquelle est accessible ledit fil de lame. To this end, the invention relates to a cold deburring knife for the edges of the periphery of the windshield, characterized in that it consists of a thin flat blade, of a blade holder in which is embedded said blade and a handle integral with the blade holder, extending the latter and whose axis is substantially parallel to the wire of the blade, said blade holder being configured in the form of a wrench head with clamping fork nut, at the bottom of the opening from which said blade wire is accessible.
Un tel outil se manipule comme un couteau, d'une seule main, le porte-lame étant engagé à cheval sur la tranche du pare-brise à ébarber, avec l'inclinaison désirée du plan de la lame par rapport aux arêtes à racler. Such a tool is handled like a knife, with one hand, the blade holder being engaged astride the edge of the windshield to be trimmed, with the desired inclination of the plane of the blade relative to the edges to be scraped.
Outre sa réelle efficacité et son maniement aisé, un tel outil est d'une sûreté très supérieure à celle des instruments utilisés jusqu'à présent pour ce genre de travail. In addition to its real efficiency and easy handling, such a tool is much safer than the instruments used until now for this kind of work.
D'autres caractéristiques et avantages ressortiront de la description qui va suivre d'un mode de réalisation préféré d'un couteau selon l'invention, description donnée à titre d'exemple uniquement et en regard du dessin annexé sur lequel
- Figure 1 est une vue en élévation latérale d'un
couteau selon l'invention, à lame mobile ;
- Figure 2 est une vue en coupe suivant la ligne II-II
du couteau de la figure 1, et
- Figure 3 est une vue en coupe suivant la ligne III
III.Other characteristics and advantages will emerge from the description which follows of a preferred embodiment of a knife according to the invention, description given by way of example only and with reference to the appended drawing in which
- Figure 1 is a side elevational view of a
knife according to the invention, with movable blade;
- Figure 2 is a sectional view along line II-II
of the knife of FIG. 1, and
- Figure 3 is a sectional view along line III
III.
Sur la figure 1, on a représenté en 1 une lame plate mince, de type conventionnel, c'est-à-dire de forme générale trapézoïdale et présentant le long de l'un de ses bords longitudinaux un fil de lame 2. In FIG. 1, a thin flat blade, of conventional type, that is to say of generally trapezoidal shape and having along one of its longitudinal edges, a blade wire 2, has been represented at 1.
En 3 est représenté un porte-lame prolongé par un manche 4 dont l'axe général est sensiblement parallèle au fil de lame 2. In 3 is shown a blade holder extended by a handle 4 whose general axis is substantially parallel to the blade wire 2.
Conformément à l'invention, le porte-lame 3 a une forme générale de tête de clé plate à fourche de serrage d'écrou, c'est-à-dire comportant deux branches 5,6 sensiblement parallèles, perpendiculaires au fil 2 de la lame, -réunies par une partie de liaison 7, définissant ainsi un évidement 8 dans le porte-lame 3, au fond duquel est disposée la lame 1. According to the invention, the blade holder 3 has the general shape of a flat wrench head with a nut tightening fork, that is to say comprising two branches 5,6 substantially parallel, perpendicular to the wire 2 of the blade, joined by a connecting part 7, thus defining a recess 8 in the blade holder 3, at the bottom of which is the blade 1.
Avantageusement, le porte-lame 3 et le manche 4 sont réalisés en deux parties en matière plastique moulée, respectivement 9 et 10 (figure 2 et 3), solidarisées entre elles par soudage ou collage suivant un plan de joint 11 sensiblement confondu avec le plan de la lame 1.Advantageously, the blade holder 3 and the handle 4 are made in two parts of molded plastic, 9 and 10 respectively (FIG. 2 and 3), joined together by welding or gluing along a joint plane 11 substantially coincident with the plane blade 1.
Les deux parties 9 et 10 sont d'épaisseur relativement faible et, dans leur zone médiane, configurées en sorte de constituer un logement 12 de réception de la lame 1, s'étendant dans l'axe du manche 4, sur toute la longueur de ce dernier, ainsi que sur presque toute la longueur du portelame 3. L'épaisseur du porte-lame 3 est sensiblement égale en tous points, excepté dans le prolongement de l'évidement 8, où les faces latérales dudit porte-lame sont inclinées en 12 en direction de la lame 1 dont le bord supérieur opposé au fil 2 est chevauché par les deux parties 9 et 10, la majeure partie de la lame 1 étant cependant exposée dans l'évidement 8, ce qui facilite le positionnement et l'orientation optimaux du couteau le long de la périphérie du pare-brise à ébarber. The two parts 9 and 10 are of relatively small thickness and, in their median zone, configured so as to constitute a housing 12 for receiving the blade 1, extending in the axis of the handle 4, over the entire length of the latter, as well as over almost the entire length of the blade holder 3. The thickness of the blade holder 3 is substantially equal in all points, except in the extension of the recess 8, where the lateral faces of said blade holder are inclined in 12 in the direction of the blade 1, the upper edge opposite the wire 2 is overlapped by the two parts 9 and 10, the major part of the blade 1 being however exposed in the recess 8, which facilitates positioning and orientation the knife along the periphery of the windshield to be trimmed.
Un tel couteau peut être manipulé en toute sécurité du fait que la partie utile de la lame, à savoir le fil 2, est situé au fond du renfoncement délimité entre les branches 5,6 et donc d'accès particulièrement protégé. Tout contact intempestif entre le fil 2 et une partie du corps du manipulateur, en particulier la main qui ne tient pas le couteau mais maintient et présente convenablement le parebrise pour l'ébarbage de son bord périphérique, est pratiquement exclu au cas où, par exemple, le couteau riperait sur le bord et irait heurter la main tenant le pare-brise. Such a knife can be handled safely because the useful part of the blade, namely the wire 2, is located at the bottom of the recess defined between the branches 5,6 and therefore of particularly protected access. Any untimely contact between the wire 2 and a part of the body of the manipulator, in particular the hand which does not hold the knife but properly maintains and presents the windshield for the deburring of its peripheral edge, is practically excluded in the case where, for example , the knife would rip on the edge and strike the hand holding the windshield.
Dans le mode de réalisation illustré, la lame 1 est introduite dans le manche 4 par l'extrémité qui est ouverte en sorte d'accéder au logement 13 de réception de la lame. In the illustrated embodiment, the blade 1 is introduced into the handle 4 through the end which is open so as to access the housing 13 for receiving the blade.
L'une des parties du manche (10) est prolongée pour servir de guide d'insertion de la lame dans son logement 13. One part of the handle (10) is extended to serve as a guide for inserting the blade into its housing 13.
De plus, la lame 1, dont on représenté en 14 la pointe avant, peut être déplacée en translation longitudinalement dans la partie avant ou nez du couteau 3a formant prolongement du porte-lame 3, afin de faire apparaitre dans l'évidement 8 une partie de fil 2 neuve. A cet effet, le nez 3a définit intérieurement un logement 13a ;dans le prolongement du logement 13 du manche 4. In addition, the blade 1, the front tip of which is shown at 14, can be moved in translation longitudinally in the front part or nose of the knife 3a forming an extension of the blade holder 3, in order to make part of the recess 8 appear. of new wire 2. To this end, the nose 3a internally defines a housing 13a; in the extension of the housing 13 of the handle 4.
La lame 1 est déplacée dans le couteau à la manière connue, à savoir à l'aide d'un poussoir 15 muni d'une patte de commande du déplacement de la lame 1, comportant un ergot pénétrant dans un trou 16 de la lame. The blade 1 is moved in the knife in the known manner, namely using a pusher 15 provided with a tab for controlling the movement of the blade 1, comprising a lug penetrating into a hole 16 in the blade.
Le poussoir 15 coulisse latéralement au manche 4 dans une rainure 17 pourvue, également à la manière connue, de dents 18 de crantage coopérant avec une saillie du poussoir 15, lequel peut également comporter un moyen de verrouillage en position, toujours à la manière connue. The pusher 15 slides laterally to the handle 4 in a groove 17 provided, also in the known manner, with teeth 18 of notching cooperating with a projection of the pusher 15, which may also include a locking means in position, always in the known manner.
I1 est à noter que le couteau de l'invention peut comporter une lame 1 amovible mais n'occupant qu'une position dans le porte-lame 3, ou bien une lame 1 fixe, le couteau étant jetable après usage. Dans les deux cas, le couteau ne présente pas de nez 3a. It should be noted that the knife of the invention can comprise a removable blade 1 but occupying only one position in the blade holder 3, or else a fixed blade 1, the knife being disposable after use. In both cases, the knife has no nose 3a.
Il est préférable que la lame 1 soit tenue ou guidée dans les deux branches en regard 5,6 et que le fil 2 soit sensiblement dans l'axe du manche 4. It is preferable that the blade 1 is held or guided in the two facing branches 5,6 and that the wire 2 is substantially in the axis of the handle 4.
La partie porte-lame 3 forme un dos d'âne en 3b, en regard de l'évidement 8, simplement pour conserver une section convenable et assurer la tenue mécanique de l'ensemble du porte-lame en dépit dudit évidement. The blade holder part 3 forms a donkey at 3b, facing the recess 8, simply to keep a suitable section and ensure the mechanical strength of the entire blade holder despite said recess.
Sur la figure 3, on a représenté en 19 une gorge longitudinale ménagée dans la partie 10 pour le coulissement de l'élément de liaison entre le poussoir 15 et la lame 1. In FIG. 3, there is shown in 19 a longitudinal groove formed in the part 10 for the sliding of the connecting element between the pusher 15 and the blade 1.
Enfin, l'invention n'est évidemment pas limitée aux modes de réalisation ci-dessus, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne les formes et dimensions du porte-lame 3, du manche 4, des branches 5,6 définissant l'accès à la lame 1, ou encore les éventuels moyens de déplacement de la lame dans le couteau. Finally, the invention is obviously not limited to the above embodiments, but on the contrary covers all variants thereof, in particular as regards the shapes and dimensions of the blade holder 3, of the handle 4, of the branches 5 , 6 defining access to the blade 1, or even the possible means of moving the blade in the knife.
