Description
La présente invention concerne un dispositif de porte lame triangulaireThe present invention relates to a triangular blade holder device
auto bloquant avec dispositif d'éjection de la lame, destiné à être utilisé pour le raclage des surfaces à nettoyer gratter ou à décaper particulièrement difficile. self-blocking device with blade ejection device, for use in scraping surfaces to be scratched or stripped particularly difficult to clean.
Ces travaux sont traditionnellement effectués à l'aide de couteaux à mastiquer ou de dispositifs nécessitant des fixations démontables types boulons. This work is traditionally done using chew knives or devices requiring bolt type removable fasteners.
Les inconvénients majeurs de ces outils sont l'usure prématurée et irrémédiable de la partie affûtée en contact avec des surfaces rugueuses et dans le cas de lames démontables le temps important demandé pour le montage et démontage de la lame, les travaux de grattage effectués avec une lame émoussée ont pour conséquence de donner un mauvais rendu d'exécution ainsi qu'une perte de temps importante. The major disadvantages of these tools are the premature and irremediable wear of the sharpened part in contact with rough surfaces and in the case of removable blades the long time required for the assembly and disassembly of the blade, the scratching work done with a blunt blade have the effect of giving a poor performance and a significant loss of time.
Le dispositif selon l'invention permet de remédier à ces inconvénients. The device according to the invention overcomes these disadvantages.
Il se présente sous la forme d'un porte-lame triangulaire où vient s'emboîter une lame interchangeable, affûtée sur trois faces. Dès que cette dernière s'émousse ne donne plus un travail satisfaisant, l'utilisateur peut la changer en quelques secondes. Il suffit de frapper la partie inférieure du manche sur le sol ou toutes autres surfaces dures afin de permettre au dispositif d'éjection interne de percuter la lame triangulaire sur la partie supérieure du manche et ainsi de la déboîter. It is in the form of a triangular blade holder which is fitted with an interchangeable blade, sharpened on three sides. As soon as it dulls no longer gives a satisfactory job, the user can change it in seconds. Just hit the bottom of the handle on the floor or any other hard surface to allow the internal ejection device to hit the triangular blade on the upper part of the handle and thus dislocate it.
Il suffit ensuite de tourner la lame triangulaire et de la positionner sur une face tranchante, puis de la frapper d'un petit coup sec soit sur le mur ou toute surface dure ou bien a l'aide d'un outillage métallique afin de permettre son remboîtement. Then simply turn the triangular blade and position it on a sharp side, then hit it with a small blow dry on the wall or any hard surface or with the help of a metal tool to allow its resocketing.
2870103 2 Ce dispositif à l'avantage en un temps minimum de mettre en permanence à disposition de l'exécutant une lame parfaitement tranchante sur un outil robuste. La présente invention supprime tous moyens de fixations démontables par exemples des boulons. Ces derniers ont les inconvénients de s'égarer ou de se détériorer facilement. 2870103 2 This device has the advantage in a minimum time to make permanently available to the performer a blade perfectly sharp on a robust tool. The present invention eliminates any means of removable fasteners for example bolts. These have the disadvantages of going astray or deteriorating easily.
Le dispositif selon invention est conçu pour résister à des températures élevées dans le cadre par exemple de décapage thermique. The device according to the invention is designed to withstand high temperatures in the setting for example of thermal pickling.
L'outil est composé d'une partie porte lame triangulaire prolongée par un tube métallique où vient s'intégrer le dispositif d'éjection le tout en métal. The tool is composed of a triangular blade holder portion extended by a metal tube which integrates the ejection device all metal.
Le porte lame triangulaire se présente sous la forme d'un fourreau, peutêtre plein ou ajouré muni sur deux faces d'une feuillure permettant le blocage de la lame triangulaire. The triangular blade holder is in the form of a sheath, may be solid or perforated provided on both sides with a rabbet for locking the triangular blade.
La lame triangulaire affûtée sur trois faces s'introduit sans peine dans le fourreau. The triangular blade sharpened on three sides is easily introduced into the sheath.
Les dessins annexés illustrent l'invention. La figure 1 représente une vue de dessus de l'ensemble du dispositif de l'invention. The accompanying drawings illustrate the invention. Figure 1 shows a top view of the entire device of the invention.
En référence à ce dessin, le dispositif comporte un porte lame triangulaire (1) avec une ouverture (2) permettant l'introduction de la lame triangulaire (6) affûtée sur trois faces, prolongé par un manche métallique (3) où vient s'intégrer le système d'éjection (4). With reference to this drawing, the device comprises a triangular blade holder (1) with an opening (2) allowing the introduction of the triangular blade (6) sharpened on three sides, extended by a metal handle (3) where s integrate the ejection system (4).
La lame triangulaire (6) s'éjecte lorsque l'on vient percuter le sol avec la partie inférieure du manche (5). The triangular blade (6) ejects when it comes to hit the ground with the lower part of the handle (5).
La lame triangulaire (6) vient s'auto bloquer dans le porte-lame triangulaire (1) dans le sens indiqué par la flèche (7). The triangular blade (6) is self-locking in the triangular blade holder (1) in the direction indicated by the arrow (7).
2870103 3 Le système d'éjection interne (4) est limité dans sa course par un rivet ou un boulon apparent (8) qui peut-être démontable afin d'assurer le nettoyage du dispositif. 2870103 3 The internal ejection system (4) is limited in its stroke by an apparent rivet or bolt (8) which may be removable to ensure the cleaning of the device.
Le système d'éjection interne (4) vient en butée sur la lame sur la partie supérieure du manche (9) afin d'en assurer un maintien renforcé. The internal ejection system (4) abuts the blade on the upper part of the handle (9) to ensure a reinforced support.
La figure 2 représente une vue de coupe de l'ensemble du dispositif de l'invention. Figure 2 shows a sectional view of the entire device of the invention.
En référence à ce dessin nous retrouvons le porte lame triangulaire (1) R) l'ouverture (2) permettant l'introduction de la lame triangulaire (6) affûtée, le manche métallique (3) et le système d'éjection interne (4). La partie inférieure du manche (5) permettant d'actionner l'éjection. Nous retrouvons le rivet ou boulon apparent (8) limiteur de course. Le système d'éjection interne (4) vient en butée sur la partie supérieure du manche (9) et sur la lame triangulaire (6) afin d'en assurer un maintien renforcé. With reference to this drawing we find the triangular blade holder (1) R) the opening (2) allowing the introduction of the sharpened triangular blade (6), the metal handle (3) and the internal ejection system (4). ). The lower part of the handle (5) for actuating the ejection. We find the rivet or apparent bolt (8) limiter race. The internal ejection system (4) abuts on the upper part of the handle (9) and on the triangular blade (6) to ensure a reinforced support.
La flèche (7) indique le sens d'introduction de la lame triangulaire (6). A titre d'exemple non limitatif: Le porte lame triangulaire en son extrémité aura une largeur de l'ordre de 8 centimètres assortie d'une ouverture de 2 mm. The arrow (7) indicates the insertion direction of the triangular blade (6). By way of non-limiting example: The triangular blade holder at its end will have a width of the order of 8 centimeters with an opening of 2 mm.
Le dispositif selon l'invention peut-être également vissé au bout d'une rallonge, plus particulièrement concernant les travaux de sol. Le dispositif selon l'invention est particulièrement destiné au raclage des surfaces à décaper ou à nettoyer par exemple dans le domaine du bâtiment. The device according to the invention can also be screwed at the end of an extension, particularly concerning the ground work. The device according to the invention is particularly intended for scraping surfaces to be stripped or cleaned, for example in the field of building.
