Description

La présente invention concerne un outil de type racloir ou grattoir, incluant une lame transversale.The present invention relates to a scraper or scraper type tool, including a transverse blade.

Il est connu d'utiliser un outil de ce type dans tout genre d'activité, notamment dans le domaine de la peinture en bâtiment pour éliminer des tâches, coulures ou traces de pinceau sur des surfaces lisses, en particulier sur des vitres.It is known to use a tool of this type in any kind of activity, especially in the field of building paint to remove stains, drips or brush marks on smooth surfaces, especially on windows.

La lame utilisable sur ce genre d'outil est en général affûtée sur ses deux bords longitudinaux et peut être montée de manière réversible dans la tête de l'outil, c'est-à-dire selon deux positions dans chacune desquelles l'un desdits bords affûtés est en position de travail.The blade used on this kind of tool is generally sharpened on its two longitudinal edges and can be mounted reversibly in the head of the tool, that is to say in two positions in each of which one of said Sharp edges is in working position.

Un type d'outils connu, de ce genre, comprend un corps en deux parties assemblables l'une à l'autre, recevant la lame entre elles et retenant cette lame lorsqu'elles sont en position d'assemblage. L'assemblage de ces deux parties est notamment réalisé au moyen d'une vis. La manipulation de cette vis n'est cependant pas très facile, et le changement de position de la lame, ou l'interchangement de cette lame n'est donc pas une opération très facile.Such a known type of tool includes a two-part body that can be assembled together, receiving the blade between them and holding the blade when in the assembly position. The assembly of these two parts is in particular achieved by means of a screw. The manipulation of this screw is however not very easy, and the change of position of the blade, or the interchange of this blade is not a very easy operation.

Un outil du même genre, également connu, comprend une tête présentant une fente terminale communiquant avec une glissière, et un porte-lame pouvant être engagé à coulissement dans cette glissière, jusqu'à une position de travail dans laquelle l'ensemble lame/porte-lame est immobilisé. La glissière présente une entrée sur un côté latéral de la tête et un rebord d'arrêt sur le côté latéral opposé de cette même tête, destiné à arrêter le porte-lame en position de travail. Le porte-lame est formé par une plaquette comprenant une face de réception de la lame, de laquelle font saillie des plots de positionnement de cette lame, et une face opposée formant des nervures de guidage du coulissement du porte-lame dans la glissière.A tool of the same type, also known, comprises a head having an end slot communicating with a slide, and a blade holder that can be slidably engaged in this slide, to a working position in which the blade / door assembly -lame is immobilized. The slide has an inlet on a lateral side of the head and a stop edge on the opposite lateral side of the same head, for stopping the blade holder in the working position. The blade holder is formed by a plate comprising a receiving face of the blade, from which projecting pins of this blade project, and an opposite face forming ribs for guiding the sliding of the blade holder in the slideway.

Cet outil existant présente également des inconvénients pratiques importants. En effet, la lame est simplement engagée sur lesdits plots de positionnement, et il existe par conséquent un risque notable d'une séparation de cette lame et du porte-lame lorsque l'ensemble n'est pas engagé dans la glissière. Cette séparation peut conduire un utilisateur à se blesser lors du retournement ou de l'interchangement de la lame. Même en l'absence d'une séparation, le deuxième bord longitudinal affûté que comprend la lame peut occasionner des blessures à l'utilisateur lors de ces manipulations. De plus, un pincement de la lame et du porte-lame doit être opéré au moment de l'engagement de l'ensemble lame/porte-lame dans la glissière, ce qui peut être difficile à réaliser. En outre, cet ensemble ne peut être engagé que d'une manière déterminée, unique, dans la glissière. Trouver immédiatement cette manière déterminée et unique d'engagement pour ne pas être évident pour certains utilisateurs, ce dont il résulte des hésitations et des difficultés de manipulation.This existing tool also has significant practical disadvantages. Indeed, the blade is simply engaged on said positioning studs, and there is therefore a significant risk of separation of this blade and the blade holder when the assembly is not engaged in the slide. This separation can lead to a user being injured during the reversal or interchange of the blade. Even in the absence of a separation, the second sharpened longitudinal edge that includes the blade can cause injuries to the user during these manipulations. In addition, a nip of the blade and the blade holder must be operated at the time of engagement of the blade / blade assembly in the slide, which can be difficult to achieve. In addition, this set can be engaged in a specific way, unique, in the slide. Find this immediately determined and unique way of commitment to not be obvious for some users, which results from hesitations and difficulties of manipulation.

Les documents US 4 617 736 A , US 2007/256306 et US 3 665 605 décrivent par ailleurs divers dispositifs selon la technique antérieure.The documents US 4,617,736 A , US 2007/256306 and US 3,665,605 also describe various devices according to the prior art.

La présente invention vise à remédier à l'ensemble des inconvénients précités.The present invention aims to remedy all of the aforementioned drawbacks.

L'outil concerné comprend, de manière connue en soi :

  • une tête présentant une fente terminale et délimitant une glissière qui communique avec cette fente ; et
  • un porte-lame apte à recevoir la lame de l'outil et à être engagé à coulissement dans ladite glissière, jusqu'à une position de travail dans laquelle un bord affûté de la lame est engagé au travers de ladite fente terminale.
The tool concerned comprises, in a manner known per se:
  • a head having a terminal slot and delimiting a slide which communicates with this slot; and
  • a blade holder adapted to receive the blade of the tool and to be slidably engaged in said slide, to a working position in which a sharp edge of the blade is engaged through said terminal slot.

Selon invention, le porte-lame comprend deux volets aptes à être placés dans une position d'écartement mutuel, dans laquelle la lame est apte à être positionnée contre l'un de ces volets, et une position de rapprochement mutuel, dans laquelle les deux volets enserrent la lame entre eux en recouvrant le bord longitudinal de la lame opposé au bord longitudinal affûté de cette lame destiné à être placé en position de travail.According to the invention, the blade holder comprises two flaps able to be placed in a position of mutual spacing, in which the blade is able to be positioned against one of these flaps, and a position of mutual approximation, in which the two shutters enclose the blade between them by covering the longitudinal edge of the blade opposite the sharp longitudinal edge of this blade to be placed in the working position.

Ainsi, le risque de séparation de la lame et du porte-lame est fortement réduit, voire éliminé, et le bord longitudinal de la lame opposé à celui destiné à être placé en position de travail est protégé, éliminant tout risque de blessure de l'utilisateur lors des manipulations de l'ensemble lame/porte-lame. Il n'est en outre plus nécessaire d'opérer un pincement de la lame et du porte-lame au moment d'introduire ledit ensemble dans la glissière.Thus, the risk of separation of the blade and the blade holder is greatly reduced or eliminated, and the longitudinal edge of the blade opposite to that intended to be placed in the working position is protected, eliminating any risk of injury to the blade. user when handling the blade / blade assembly. It is furthermore no longer necessary to pinch the blade and the blade holder when introducing said assembly into the slideway.

Avantageusement, les deux volets présentent des formes symétriques par rapport à un plan longitudinal médian du porte-lame.Advantageously, the two flaps have symmetrical shapes with respect to a median longitudinal plane of the blade holder.

Cette symétrie permet d'engager l'ensemble lame/porte-lame dans la glissière par l'une ou l'autre des extrémités longitudinales de ce porte-lame, ce qui, en comparaison de l'outil connu précité, simplifie grandement l'opération de remise en place dudit ensemble sur la tête de l'outil. En effet, dans l'outil connu précité, le porte-lame est formé par une plaquette unique, n'ayant pas une forme symétrique de part et d'autre d'un plan médian longitudinal confondu avec la lame.This symmetry makes it possible to engage the blade / blade holder assembly in the slideway by one or the other of the longitudinal ends of this blade holder, which, in comparison with the aforementioned known tool, greatly simplifies the repositioning operation of said assembly on the head of the tool. Indeed, in the aforementioned known tool, the blade holder is formed by a single plate, not having a symmetrical shape on either side of a longitudinal median plane coincides with the blade.

Dans le même but de simplification de la manipulation de l'outil, ladite glissière présente à chacune de ses extrémités longitudinales une ouverture permettant l'engagement dudit ensemble lame/porte-lame.For the same purpose of simplifying the handling of the tool, said slide has at each of its longitudinal ends an opening for engaging said blade / blade holder assembly.

Cet ensemble peut ainsi être engagé soit par le côté gauche soit par le côté droit de la glissière, ce qui rend l'outil selon l'invention aisément manipulable, tant par un gaucher que par un droitier.This assembly can thus be engaged either by the left side or by the right side of the slide, which makes the tool according to the invention easily manipulated by both left-handed and right-handed.

De préférence,

  • l'un des volets du porte-lame comprend, au moins un doigt élastiquement déformable, présentant une extrémité d'arrêt, et
  • la tête de l'outil présente un rebord d'arrêt apte à coopérer avec cette extrémité d'arrêt lorsque ledit ensemble lame/porte-lame se trouve dans ladite position de travail,
ce doigt étant apte à être déformé de telle sorte qu'il puisse, ainsi que son extrémité d'arrêt, être inscrit à l'intérieur du profil du porte-lame, de manière à ne pas faire obstacle à l'engagement de ce porte-lame dans la glissière, et, lorsque ladite extrémité d'arrêt se trouve en face dudit rebord d'arrêt, à réaliser l'engagement de cette extrémité derrière ce rebord d'arrêt par rappel élastique.Preferably,
  • one of the blades of the blade holder comprises at least one elastically deformable finger having a stop end, and
  • the head of the tool has a stop flange adapted to cooperate with this stop end when said blade / blade assembly is in said working position,
this finger being able to be deformed so that it can, as well as its stop end, be inscribed inside the profile of the blade holder, so as not to hinder the engagement of this door -lame in the slide, and when said stop end is in front of said stop flange, to achieve the engagement of this end behind the stop barrier by resilient return.

Ce doigt et ce rebord d'arrêt forment ainsi des moyens d'immobilisation de l'ensemble lame/porte-lame dans la position de travail.This finger and this stop flange thus form means for immobilizing the blade / blade assembly in the working position.

De préférence, ledit rebord d'arrêt est aménagé sur le côté de la tête de l'outil situé à l'opposé de ladite fente terminale, et le doigt correspondant du porte-lame est disposé de manière à ce que son extrémité d'arrêt se trouve sur l'extérieur de la tête de l'outil lorsqu'elle est engagée derrière le rebord d'arrêt.Preferably, said stop edge is arranged on the side of the head of the tool located opposite said terminal slot, and the corresponding finger of the blade holder is arranged in such a way that its stop end is on the outside of the tool head when engaged behind the stop edge.

Ainsi, l'extrémité d'arrêt est accessible depuis l'extérieur de la tête de l'outil et peut être facilement dégagée de derrière le rebord d'arrêt et être pressée en direction de l'intérieur de la glissière de manière à libérer le porte-lame de son verrouillage en position de travail.Thus, the stopping end is accessible from the outside of the tool head and can be easily disengaged from behind the stopping edge and pressed toward the inside of the slider to release the blade holder from its lock in working position.

Selon une forme de réalisation préférée de l'invention, dans ce cas,

  • le porte-lame comprend deux doigts tels que précités, disposés de telle sorte que l'extrémité d'arrêt d'un premier doigt se trouve au niveau de l'une des extrémités longitudinales du porte-lame et que l'extrémité d'arrêt du deuxième doigt se trouve au niveau de l'autre extrémité longitudinale du porte-lame ; les deux doigts sont en outre disposés en opposition l'un par rapport à l'autre, c'est-à-dire en étant symétriques par rapport à un plan médian transversal du porte-lame ; et
  • la tête de l'outil comprend deux rebords d'arrêt tels que précités.
According to a preferred embodiment of the invention, in this case,
  • the blade holder comprises two fingers as mentioned above, arranged so that the stop end of a first finger is at one of the longitudinal ends of the blade holder and that the stop end the second finger is at the other longitudinal end of the blade holder; the two fingers are further arranged in opposition to one another, that is to say being symmetrical with respect to a transverse median plane of the blade holder; and
  • the head of the tool comprises two stop edges as mentioned above.

Ainsi, lorsque l'extrémité d'arrêt du doigt que comprend l'extrémité longitudinale du porte-lame qui a été engagée en premier dans la glissière arrive en engagement derrière le rebord d'arrêt correspondant, l'extrémité d'arrêt du doigt que comprend l'autre extrémité longitudinale du porte-lame arrive alors à proximité du rebord d'arrêt correspondant ; le porte-lame est ainsi calé en position de travail par ce double engagement desdites extrémités d'arrêt. Pour libérer le porte-lame de cette position de travail, l'utilisateur peut agir indifféremment sur l'une ou l'autre de ces extrémités d'arrêt, ce qui contribue encore à rendre très simple la manipulation de l'outil.Thus, when the stop end of the finger that comprises the longitudinal end of the blade holder which was engaged first in the slide arrives in engagement behind the corresponding stop edge, the finger stop end that comprises the other longitudinal end of the blade holder then comes close to the corresponding stop edge; the blade holder is thus locked in the working position by this double engagement of said stop ends. To release the blade holder from this working position, the user can act indifferently on one or the other of these stop ends, which further contributes to making the handling of the tool very simple.

De préférence, les deux volets du porte-lame sont reliés l'un à l'autre par une charnière.Preferably, the two flaps of the blade holder are connected to each other by a hinge.

Le porte-lame a ainsi une structure unitaire, et ladite charnière enveloppe au moins en partie ledit bord longitudinal opposé, assurant une sécurité parfaite.The blade holder thus has a unitary structure, and said hinge at least partially envelops said opposite longitudinal edge, ensuring perfect security.

Le maintien des deux volets en position de rapprochement peut être réalisé par un moyen élastique de rappel des volets dans cette position de rapprochement, notamment, lorsque ladite charnière est formée par une charnière-film, par une élasticité du matériau constituant cette charnière-film. Les volets pourraient également comprendre des moyens de maintien venant en coopération les uns avec les autres lorsque ces volets sont dans ladite position de rapprochement, cette coopération assurant le maintien de ces volets dans cette position de rapprochement.Maintaining the two flaps in the approaching position can be achieved by an elastic means of return flaps in this approach position, in particular, when said hinge is formed by a hinge-film, by an elasticity of the material constituting the hinge-film. The flaps could also comprise holding means cooperating with each other when these flaps are in said approaching position, this cooperation ensuring the maintenance of these flaps in this approach position.

Avantageusement, l'outil comprend un capot de protection apte à être monté sur ladite tête, et à être retenu sur celle-ci, dont au moins une des extrémités longitudinales est dépourvue de paroi transversale d'extrémité, de manière à permettre un engagement du porte-lame dans ladite glissière, ou un retrait de ce porte-lame hors de cette glissière, alors même que ce capot est en place sur ladite tête.Advantageously, the tool comprises a protective cover adapted to be mounted on said head, and to be retained thereon, of which at least one of the longitudinal ends is devoid of end transverse wall, so as to allow a engagement of the blade holder in said slide, or a withdrawal of this blade holder out of this slide, even though this hood is in place on said head.

Une parfaite protection est ainsi assurée à l'utilisateur lors du coulissement du porte-lame dans la glissière.Perfect protection is thus provided to the user when sliding the blade holder in the slide.

L'invention sera bien comprise, et d'autres caractéristiques et avantages de celle-ci apparaîtront, en référence au dessin schématique annexé, représentant, à titre d'exemple non limitatif, une forme de réalisation préférée de l'outil concerné.

Le corps 5 de l'outil inclut un manche 7 et une tête 8, notamment formés par moulage en une seule pièce d'une ou plusieurs matières synthétiques.The body 5 of the tool includes a handle 7 and a head 8, in particular formed by molding in one piece of one or more synthetic materials.

En référence à l'ensemble des figures, il apparaît que la tête 8 comprend une fente terminale 10, une glissière 11 et deux rebords d'arrêt 12 au niveau de ses extrémités longitudinales.Referring to all the figures, it appears that the head 8 comprises an end slot 10, a slide 11 and two stop edges 12 at its longitudinal ends.

La fente 10 s'étend sur toute la longueur de la tête 8 et est destinée à permettre le passage de la lame 2.The slot 10 extends over the entire length of the head 8 and is intended to allow the passage of the blade 2.

La glissière 11 s'étend également sur toute la longueur de la tête 8 et communique entièrement avec la fente 10. Elle débouche sur les côtés latéraux de la tête 8 par deux ouvertures permettant l'introduction en elle de l'ensemble lame 2/porte-lame 6. Elle inclut deux rainures de guidage du coulissement du porte-lame 6, celui-ci présentant des nervures de guidage 13 correspondantes.The slide 11 also extends over the entire length of the head 8 and communicates fully with the slot 10. It opens on the lateral sides of the head 8 by two openings for the introduction into it of the blade assembly 2 / door -lame 6. It includes two grooves for guiding the sliding of the blade holder 6, the latter having corresponding guide ribs 13.

Chaque rebord d'arrêt 12 est formé au niveau des extrémités longitudinales de la tête 8, en étant délimité par le fond de la glissière 11, d'une part, et par un chanfrein formé sur la tête 8 du côté opposé à la fente 10.Each stop flange 12 is formed at the longitudinal ends of the head 8, being delimited by the bottom of the slide 11, on the one hand, and by a chamfer formed on the head 8 on the side opposite the slot 10 .

Comme le montrent plus particulièrement les figures 3 à 5, le porte-lame 6 comprend, outre les nervures 13, deux volets 15, une charnière-film 16 reliant ces deux volets 15 l'un à l'autre, et deux doigts 17 de verrouillage du porte-lame 6 en position de travail, par coopération avec les rebords d'arrêt 12.As shown more particularly by Figures 3 to 5 , the blade holder 6 comprises, besides the ribs 13, two flaps 15, a hinge-film 16 connecting these two flaps 15 to one another, and two fingers 17 for locking the blade holder 6 in the working position, by cooperation with the stop edges 12.

L'un des volets 15 comprend trois plots 20 de positionnement de la lame 2, celle-ci comprenant des ouvertures correspondantes, et l'autre volet 15 comprend des ouvertures 21 aptes à loger ces plots 20 lorsque les volets 15 sont en position rabattue l'un contre l'autre, ainsi que le montre la figure 5.One of the flaps 15 comprises three studs 20 for positioning the blade 2, the latter comprising corresponding openings, and the other flap 15 comprises openings 21 able to accommodate these studs 20 when the flaps 15 are in the folded position. against each other, as shown by the figure 5 .

Il apparaît sur cette figure 5 qu'à l'exception de ces plots 20 et ouvertures 21, les deux volets 15 présentent des formes symétriques par rapport à un plan médian longitudinal du porte-lame 6, qui est un plan passant par la lame 2 lorsque celle-ci est en place dans le porte-lame 6, comme cela est représenté sur cette figure 5.He appears on this figure 5 except that these studs 20 and openings 21, the two flaps 15 have symmetrical shapes with respect to a longitudinal median plane of the blade holder 6, which is a plane passing through the blade 2 when it is in place in the blade holder 6, as shown in this figure 5 .

La charnière-film 16 est formé en une seule et même pièce avec les volets 15. Comme cela se comprend, elle permet aux volets 15 de pouvoir être placés dans la position d'écartement mutuel montré sur la figure 3, dans laquelle la lame 2 est apte à être positionnée contre l'un de ces volets, et la position de rapprochement mutuel montrée sur les figures 4 et 5, dans laquelle les deux volets 15 enserrent la lame 2 entre eux. Dans cette position, le porte-lame 6 forme un étui recouvrant le bord longitudinal 2b de la lame 2 opposé au bord longitudinal 2a destiné à être placé en position de travail.The hinge-film 16 is formed in one and the same piece with the flaps 15. As can be understood, it allows the flaps 15 to be placed in the mutual spacing position shown on the figure 3 , in which the blade 2 is adapted to be positioned against one of these flaps, and the mutual approach position shown on the Figures 4 and 5 , in which the two flaps 15 enclose the blade 2 between them. In this position, the blade holder 6 forms a holster covering the longitudinal edge 2b of the blade 2 opposite the longitudinal edge 2a intended to be placed in the working position.

La charnière-film 16 s'interrompt à distance des extrémités longitudinales des volets 15, et ces derniers comprennent des dégagements 22 permettant le mouvement des volets 15 l'un par rapport à l'autre nonobstant la présence des doigts 17. Grâce à ces dégagements 22, les deux doigts 17 sont situés à l'extérieur de l'étui formé par le porte-lame 6 lorsque les volets 15 sont en position de rapprochement, ainsi que le montrent particulièrement les figures 1 et 4.The film hinge 16 stops at a distance from the longitudinal ends of the flaps 15, and the latter comprise clearances 22 allowing the flaps 15 to move relative to each other, notwithstanding the presence of the fingers 17. Thanks to these clearances 22, the two fingers 17 are located outside the holster formed by the blade holder 6 when the flaps 15 are in the approaching position, as shown particularly by the figures 1 and 4 .

Chaque doigt 17 présente un corps allongé élastiquement déformable et une extrémité d'arrêt 25 épaissie, formant un épaulement d'arrêt 26 avec ce corps. Les deux doigts 17 sont, ainsi que le montre la figure 4, disposés de telle sorte que l'extrémité d'arrêt 25 d'un premier doigt 17 se trouve au niveau de l'une des extrémités longitudinales du porte-lame 6 et que l'extrémité d'arrêt 25 du deuxième doigt 17 se trouvant au niveau de l'autre extrémité longitudinale du porte-lame 6. De plus, les deux doigts 17 sont disposés en opposition l'un par rapport à l'autre, c'est-à-dire en étant symétriques par rapport à un plan médian transversal du porte-lame 6 (qui est le plan de la coupe montrée sur la figure 5).Each finger 17 has an elongated elastically deformable body and a thickened stop end 25 forming a stop shoulder 26 with this body. The two fingers 17 are, as shown by figure 4 , arranged such that the stop end 25 of a first finger 17 is at one of the longitudinal ends of the blade holder 6 and that the stop end 25 of the second finger 17 being located at the other longitudinal end of the blade holder 6. In addition, the two fingers 17 are arranged in opposition to one another, that is to say being symmetrical with respect to a plane transverse median of the blade holder 6 (which is the plane of the cut shown on the figure 5 ).

En pratique, comme cela se comprend en référence aux figures 6 et 7, le doigt 17 situé sur l'extrémité du porte-lame 6 introduite en premier dans la glissière 11 est apte à être déformé de telle sorte qu'il puisse, ainsi que son extrémité d'arrêt 25, être inscrit à l'intérieur du profil du porte-lame 6, afin de ne pas faire obstacle à l'engagement de ce porte-lame 6 dans la glissière 11 ; lorsque l'épaulement 26 de cette extrémité d'arrêt 25 se trouve en face du rebord d'arrêt 12 correspondant, le rappel élastique du doigt 17 réalise l'engagement de cet épaulement 26 derrière le rebord d'arrêt 12. Dans cette position, l'extrémité d'arrêt 25 du doigt 17 de l'autre extrémité longitudinale du porte-lame 6 arrive à proximité du rebord d'arrêt 12 correspondant, de sorte que le porte-lame 6 est calé en position de travail par ce double engagement desdites extrémités d'arrêt 25 avec les rebords 12. Pour libérer le porte-lame 6 de cette position de travail, l'utilisateur peut agir indifféremment sur l'une ou l'autre de ces extrémités d'arrêt 25, qui dépassent en dehors de la tête 8, ainsi que le montrent la figure 2.In practice, as is understandable with reference to Figures 6 and 7 , the finger 17 located on the end of the blade holder 6 introduced first into the slide 11 is adapted to be deformed so that it can, as well as its stop end 25, be inscribed inside the profile of the blade holder 6, so as not to hinder the engagement of this blade holder 6 in the slide 11; when the shoulder 26 of this stop end 25 is in front of the corresponding stop edge 12, the elastic return of the finger 17 makes the engagement of this shoulder 26 behind the stop flange 12. In this position, the stop end 25 of the finger 17 of the other longitudinal end of the blade holder 6 comes close to the corresponding stop edge 12, so that the blade holder 6 is wedged in the working position by this double engagement said stops 25 with the flanges 12. To release the blade holder 6 from this working position, the user can act indifferently on one or the other of these stop ends 25, which protrude beyond of the head 8, as shown by figure 2 .

Les symétries précitées de ces doigts 17 et du porte-lame 6 permettent d'engager l'ensemble lame 2/porte-lame 6 dans la glissière 11 par l'une ou l'autre des extrémités longitudinales de ce porte-lame 6, et ce dernier peut être engagé dans la glissière 11 par l'une ou l'autre des ouvertures d'extrémité de cette glissière 11. L'opération de mise en place ou de remise en place dudit ensemble sur la tête 8 de l'outil est ainsi grandement facilitée, sans que des hésitations soient générées chez l'utilisateur en ce qui concerne le sens correct d'engagement.The aforementioned symmetries of these fingers 17 and the blade holder 6 allow to engage the blade assembly 2 / blade holder 6 in the slide 11 by one or other of the longitudinal ends of the blade holder 6, and the latter can be engaged in the slide 11 by one or the other of the end openings of this slide 11. The operation of placing or replacing said assembly on the head 8 of the tool is thus greatly facilitated, without hesitations being generated at the user with regard to the correct direction of engagement.

En outre, le porte-lame 6, par sa structure en étui enveloppant le bord affûté 2b inutilisé, réduit fortement, voire élimine, le risque de séparation de la lame 2 et du porte-lame 6, éliminant ainsi tout risque de blessure de l'utilisateur lors des manipulations de l'ensemble lame 2/porte-lame 6. Il n'est en outre pas nécessaire pour l'utilisateur d'opérer un pincement de la lame et du porte-lame au moment d'introduire ledit ensemble dans la glissière 11.In addition, the blade holder 6, with its case structure wrapping the sharp edge 2b unused, greatly reduces or eliminates the risk of separation of the blade 2 and the blade holder 6, eliminating any risk of injury to the blade. the user during handling of the blade assembly 2 / blade holder 6. It is further not necessary for the user to operate a pinch of the blade and the blade holder when introducing said assembly into the slide 11.

La figure 8 montre l'outil 1 dont la tête 8 est équipée d'un capot de protection 30, apte à être monté sur cette tête, et à être retenu sur celle-ci, par frottements. Les deux extrémités longitudinales sont dépourvues de parois transversales d'extrémité, de manière à permettre un engagement du porte-lame 6 dans la glissière 11, ou un retrait de ce porte-lame 6 hors de cette glissière 11, alors même que ce capot 30 est en place sur la tête 8.The figure 8 shows the tool 1 whose head 8 is equipped with a protective cap 30, adapted to be mounted on this head, and to be retained thereon, by friction. Both longitudinal ends are devoid of end transverse walls, so as to allow engagement of the blade holder 6 in the slide 11, or a withdrawal of the blade holder 6 out of this slide 11, even though this cover 30 is in place on the head 8.

Comme cela apparaît de ce qui précède, l'invention fournit un outil de type racloir ou grattoir, incluant une lame transversale, qui présente les avantages déterminants précités par rapport aux outils homologues de la technique antérieure.As is apparent from the foregoing, the invention provides a scraper or scraper type tool, including a transverse blade, which has the above-mentioned critical advantages over prior art counterparts.
