Abstract

The invention relates to a device making it possible to cut materials such as: natural or artificial slates, while minimising the risks of the cuttings falling and enabling these cuttings to be recovered. It consists of a plate 1, a guide 2 which is adjustable 13 enabling cutting in series and a blade 3 activated by a handle 8. The blade 3 is articulated on a spindle and moves down in a longitudinal slot 10 made up of two metal cutters 4, each of these ''cutters'' having a sharp edge 12 facing the blade, and a removable bent fixing tab 6 held by screws 5 in oblong housings 15 holds the apparatus on the roof. A rim 7 enables the cutting to be collected. When the user pivots, with or without demultiplication, the blade 3 about the spindle, the slate laid previously on the plate 1 is locally crushed and then ground by being lowered into the groove 10 defined by the ''cutters'' 4.

Description

Dispositif de coupe des ardoises naturelles ou
artificielles utilisable directement sur
un toit
La présente invention concerne un dispositif permettant de couper les matériaux tels que les ardoises naturelles ou artificielles sur les toits, sans effort et en minimisant les risques et les pertes de. matières.Device for cutting natural slates or
artificial usable directly on
a roof
The present invention relates to a device for cutting materials such as natural or artificial slates on roofs, effortlessly and minimizing the risks and losses of. materials.

Les machines à couper les ardoises ou similaires connues à ce jour sont essentiellement des machines électriques dont la vitesse de rotation de l'outil tranchant utilise une coupe nette sur les deux faces de l'ardoise, alors q-u'il est nécessaire pour assurer la bonne étanchéité de la toiture que la coupe soit nette sur une face et présente un défoncé sur l'autre face que les spécialistes appellent biseaux. The slate cutting machines or the like known to date are essentially electric machines whose speed of rotation of the cutting tool uses a clean cut on both sides of the slate, so that it is necessary to ensure good waterproofing of the roof so that the cut is clear on one side and has a knockout on the other side that specialists call bevels.

I1 existe également des machines manuelles dont I 'encom- brement et le mécanisme complexe à roulement à billes et molettes nécessitent un effort important qui exclue leur utilisation sur un toit. There are also manual machines whose size and complex mechanism with ball bearings and knurls require a significant effort which excludes their use on a roof.

Actuellement, les artisans couvreurs continuent à utiliser le marteau et l'enclume d'ardoisier, opération longue et delicate nécessitant un traçage préalable sur toutes les ardoises à couper et dans laquelle la partie d'ardoise inutile ne peut être retenue par l'utilisateur et est nécessairement perdue lors de sa chute. La présente invention permet d' éviter tous les inconvénients précités. Currently, roofing craftsmen continue to use the hammer and the slate anvil, a long and delicate operation requiring prior tracing on all the slates to be cut and in which the useless slate part cannot be retained by the user and is necessarily lost when it falls. The present invention avoids all the aforementioned drawbacks.

Le principe de fonctionnement consiste à faire descendre, avec ou sans démultiplication de I'eff,ort exercé, une lame métallique pivotant autour de son axe. The operating principle consists in bringing down, with or without reduction of the force exerted, a metal blade pivoting around its axis.

L'ardoise posée sur un plateau rainuré sera,localement au niveau de la partie recouvrant la rainureZécrasée puis broyée par la descente de la lame dans ladite rainure. La découpe totale ou partielle se fera à la demande de l'utilisateur en fonction de la descente de la lame et du positionnement de l'ardoise par butée latérale .réglable.  The slate placed on a grooved tray will be locally at the level of the part covering the crushed groove and then crushed by the descent of the blade in said groove. The total or partial cutting will be done at the request of the user depending on the descent of the blade and the positioning of the slate by .adjustable lateral stop.

Tel qu'il est représenté sur les dessins figures I à 3 le dispositif comprend : Un plateau (I) d'une matière quelconque résistante et légère. Une butée formant guide (2) réglable de coupe articulée et coulissante sur un axe perpendiculaire (13) à ladite butée permettant la découpe en séries identiques ou non, une lame métallique (3), terminée par un manche (8) en matière isolante appropriée. As shown in the drawings in Figures I to 3, the device comprises: A plate (I) of any resistant and light material. An adjustable guide stop (2) of articulated and sliding cut on an axis perpendicular (13) to said stop allowing the cutting in identical or different series, a metal blade (3), terminated by a handle (8) of suitable insulating material .

La lame (3) a un tranchant plat (il) faisant un angle de 90" par rapport aux faces latérales de deux arètes paral lèles et d'un profillongitudinal en V aplati. The blade (3) has a flat cutting edge (it) making an angle of 90 "with respect to the lateral faces of two parallel parallel edges and of a flattened V-profile.

Ladite lame (3) s'articule en son extrémité opposée au manche (8) sur un axe (9) perpendiculaire disposé sous le plateau et descend dans une fente lonitudinale (10) définie

Figure img00020001

par 2 "couteaux"1(4) présentant en regard de la lame une arète vive (12) dont l'écartement est prévu pour laisser passer librement la lame avec jeu. Une patte recourbée de fixation effaçable (6) disposée sur la tranche du plateau proche de l'axe de l'articulation de la lame maintenue par des vis (5) dans les logements oblongs (15) permet à l'utilisateur de disposer de ses deux mains pour travailler du fait que cette patte permet la fixation sur le toit par exemple sur une latte de celui-ci, et un rebord supérieur (7) disposé sur la tranche opposée du plateau (1) permet de récupérer la chute du matériau coupé.Said blade (3) is articulated at its end opposite to the handle (8) on a perpendicular axis (9) disposed under the plate and descends into a defined longitudinal slot (10)
Figure img00020001

by 2 "knives" 1 (4) having a sharp edge (12) opposite the blade, the spacing of which is provided to allow the blade to pass freely with play. A curved erasable fixing tab (6) disposed on the edge of the plate close to the axis of the blade articulation held by screws (5) in the oblong housings (15) allows the user to have both hands to work because this tab allows fixing on the roof for example on a slat thereof, and an upper edge (7) disposed on the opposite edge of the plate (1) allows to recover the fall of the cut material.

Une variante de la présente invention illustrée en figure 4 permet d'amplifier l'effort exercé sur le manche (8') à l'aide, par exemple, d'un volant démultiplicateur (14) articulé autour d'un axe excentré et relié audit levier et prenant appui sur l'arète supérieure de la lame, un ressort (17) maintenant la lame en position haute au repos et étant associé à une patte d'appui et de maintient (16) de l'ardoise lors de la coupe. A variant of the present invention illustrated in FIG. 4 makes it possible to amplify the force exerted on the handle (8 ′) using, for example, a reduction gear (14) articulated around an eccentric axis and connected to said lever and bearing on the upper edge of the blade, a spring (17) holding the blade in the high position at rest and being associated with a support and holding tab (16) of the slate during cutting .

Le dispositif selon l'invention est particulièrement destiné à la découpe de matériaux de couverture tels qu'ar- doises naturelles ou artificielles, fibrociments, éléments de couverture plats ou synthétiques de type "SHINGEL" ou autres. The device according to the invention is particularly intended for cutting roofing materials such as natural or artificial slabs, fiber cement, flat or synthetic roofing elements of the "SHINGEL" type or others.

Les détails de réalisation peuvent être modifiés sans s 1écarter de l'invention, dans le domaine des équivalences techniques.  The details of construction can be modified without departing from the invention, in the field of technical equivalences.
