Description

INSTRUMENT ET PROCEDE DE TRAÇAGE POUR LA DECOUPE D'ELEMENTS DEDRAWING INSTRUMENT AND METHOD FOR CUTTING ELEMENTS OF
REVETEMENTSCOATINGS
La présente invention a trait aux différentes techniques de mise en oeuvre pour la pose d'éléments de revêtement et trouve ses applications immédiates dans le domaine du bâtiment ou des travaux publics.The present invention relates to different implementation techniques for laying covering elements and finds its immediate applications in the field of building or public works.
L'invention s'adresse plus particulièrement aux revêtements de sols selon l'opération proprement dite de carrelage qui consiste à assembler, sur un bain de mortier ou de colle, des carreaux de céramique, de faïence ou de grès, de manière à former un pavage ou un revêtement. Ces carreaux, formant les revêtements de sol en éléments de faible épaisseur et de petite surface, adoptent des figures polygonales diverses dont la plus courante, le carré, sera prise en appui de la démonstration de la présente invention sans constituer pour autant une limitation d'applications aux autres figures.The invention relates more particularly to floor coverings according to the actual operation of tiling which consists in assembling, on a bath of mortar or glue, ceramic, earthenware or sandstone tiles, so as to form a paving or coating. These tiles, forming the floor coverings in elements of small thickness and small area, adopt various polygonal figures, the most common of which, the square, will be taken to support the demonstration of the present invention without however constituting a limitation of applications to other figures.
Les techniques utilisées antérieurement pour la pose des carrelages ou pavés à proximité immédiate d'éléments tels que huisseries de portes, seuils, escaliers ou autres, présentent des difficultés de découpe harmonieuse pour enrober parfaitement ces obstacles. Concernant la pose des pavés, pour place publique par exemple, les obstacles rencontrés tels que monuments, fontaines, escaliers ou autres, les difficultés sont du même ordre que pour le carrelage traditionnel. Effectivement, les carreaux ou pavés sont placés de manière approximative et les découpes destinées à enrober parfaitement les obstacles sont parfois nombreuses et souvent disgracieuses. Les mortiers ou ciments ou colles utilisés pour combler les joints ne sont jamais du même coloris que le carrelage ou pavé, montrant encore plus l'accent sur les défauts des découpes autour desdits obstacles.The techniques used previously for laying tiles or cobblestones in the immediate vicinity of elements such as door frames, thresholds, stairs or others, present difficulties in harmonious cutting to perfectly coat these obstacles. Concerning the laying of pavers, for public places for example, obstacles encountered such as monuments, fountains, stairs or others, the difficulties are of the same order as for traditional tiling. Indeed, the tiles or pavers are placed in an approximate manner and the cutouts intended to perfectly coat the obstacles are sometimes numerous and often unsightly. The mortars or cements or glues used to fill the joints are never the same color as the tiling or paving, showing even more emphasis on the defects of the cuts around said obstacles.
Ces problèmes de découpe résultent essentiellement du fait que le temps nécessaire au repérage et au traçage de l'empreinte de l'obstacle à enrober est important car ces opérations sont réalisées manuellement à l'aide de mesures au dos des éléments de revêtement, ce qui augmente notablement le coût des opérations de pose. Ces opérations de repérage et de traçage sont d'autant plus longues que les obstacles présentent des pans obliques par rappon au revêtement ou que les éléments de ce dernier sont posés en diagonale par rapport auxdits obstacles.These cutting problems are mainly due to the fact that the time required identifying and tracing the imprint of the obstacle to be coated is important because these operations are carried out manually using measurements on the back of the covering elements, which significantly increases the cost of the laying operations. These tracking and tracing operations are all the longer as the obstacles have oblique sections in response to the covering or that the elements of the latter are placed diagonally with respect to said obstacles.
Partant de cet état de fait et d'un cahier des charges préétablies reposant sur le fait que les gabarits de traçage existants à ce jour ne repèrent pas l'emplacement exact de l'empreinte de l'obstacle par rapport au revêtement posé, le demandeur a mené des recherches ayant pour objet l'étude d'un instrument de traçage qui remédie aux inconvénients précités et qui permette la découpe d'éléments de revêtement destinés à enrober les contours d'un obstacle, dans des conditions de pose satisfaisantes, tout en favorisant une large diffusion d'un tel instrument en veillant à son moindre prix de revient. Pour ce faire, l'instrument de traçage de l'invention s'efforce de concilier en un seul produit industriel, le traçage de l'empreinte de l'obstacle et le repérage de la même empreinte sur un élément à poser par rapport à un revêtement en place.On the basis of this state of affairs and of a pre-established specification based on the fact that the layout templates existing to date do not identify the exact location of the imprint of the obstacle in relation to the coating laid, the applicant has carried out research aimed at studying a tracing instrument which overcomes the aforementioned drawbacks and which allows the cutting of covering elements intended to coat the contours of an obstacle, under satisfactory laying conditions, while promoting the wide dissemination of such an instrument while ensuring its lower cost price. To do this, the tracing instrument of the invention endeavors to reconcile in a single industrial product, the tracing of the imprint of the obstacle and the location of the same imprint on an element to be laid in relation to a coating in place.
A cet effet, l'instrument de traçage de l'invention est constitué par la combinaison :To this end, the tracing instrument of the invention consists of the combination:
- d'un gabarit susceptible d'épouser les contours dudit obstacle, - d'une pièce de centrage qui, comportant un croisillon destiné à venir se caler dans l'intersection des joints d'éléments du revêtement en place, permet de caler ledit instrument par rapport à un repère dudit revêtement de manière à définir le repérage dudit obstacle à enrober par rapport à un point précis du revêtement posé,- a template capable of marrying the contours of said obstacle, - a centering piece which, comprising a crosspiece intended to wedge in the intersection of the joints of elements of the coating in place, makes it possible to wedge said instrument with respect to a marker of said covering so as to define the marking of said obstacle to be coated with respect to a specific point of the covering laid,
- et d'une règle qui, formant entretoise entre ledit gabarit et ladite pièce de centrage, permet de maintenir l'écarterr-ent et l'orientation entre les deux.- And a rule which, forming a spacer between said template and said centering piece, keeps the spread-ent and the orientation between the two.
Cet instrument de traçage se compose donc de trois parties élémentaires ayant chacun une fonction distincte coopérant avec les deux autres .This tracing instrument therefore consists of three elementary parts each having a distinct function cooperating with the other two.
D'une part, le gabarit a pour objet de reproduire l'empreinte de l'obstacle à enrober tout en étant maintenu à une distance fixe de la pièce de centrage grâce à la règle. D'autre part, la pièce de centrage a pour objet, grâce à la règle, de repérer la position du gabarit par rapport à un point choisi du revêtement afin de pouvoir positionner l'empreinte à tracer au bon endroit de l'élément à découper.On the one hand, the template aims to reproduce the imprint of the obstacle to be coated while being kept at a fixed distance from the centering piece thanks to the ruler. On the other hand, the purpose of the centering piece is, by virtue of the ruler, to identify the position of the template with respect to a chosen point of the coating in order to be able to position the imprint to be traced in the right place of the element to be cut. .
Et enfin, la règle a pour objet de maintenir l'écartement entre le gabarit et l'organe de centrage ainsi que l'orientation entre les deux de manière à pouvoir déplacer l'ensemble tout en maintenant les mêmes paramètres.And finally, the purpose of the rule is to maintain the spacing between the template and the member centering as well as the orientation between the two so as to be able to move the assembly while maintaining the same parameters.
Selon une caractéristique particulièrement avantageuse de l'invention, le gabarit est monté à une extrémité de la règle et la susdite pièce de centrage est montée coulissante le long de cette dernière de manière à ajuster la distance séparant les deux quel que soit l'éloignement de l'obstacle. L'utilité de cette mobilité linéaire le long de la règle est de régler l'écartement entre la pièce de centrage et le gabarit pour l'adapter aux différentes dimensions d'éléments posés d'une part et pour pouvoir positionner la pièce de centrage à un point stratégique plus ou moins éloigné de l'obstacle à enrober d'autre part Selon une autre caractéristique particulièrement avantageuse de l'invention, le susdit gabarit est monté articulé autour d'un axe perpendiculaire à l'extrémité de la règle de manière à guider l'empreinte du gabarit quelle que soit l'orientation de l'obstacle. L'utilité de ce mouvement articulé du gabarit autour de l'extrémité de la règle est de répondre aux différents angles de présentation des obstacles à enrober. Selon une autre caractéristique particulièrement avantageuse de l'invention, la pièce de centrage est montée articulée autour d'un axe perpendiculaire à la règle de manière à orienter la règle et le gabarit y associé, quelle que soit la position du repère du revêtement en place où est calée la pièce de centrage.According to a particularly advantageous characteristic of the invention, the template is mounted at one end of the rule and the said centering piece is slidably mounted along the latter so as to adjust the distance separating the two regardless of the distance from the obstacle. The utility of this linear mobility along the ruler is to adjust the spacing between the centering piece and the template to adapt it to the different dimensions of elements placed on the one hand and to be able to position the centering piece at According to another particularly advantageous characteristic of the invention, the above-mentioned template is mounted articulated around an axis perpendicular to the end of the rule so as to have a strategic point more or less distant from the obstacle to be coated. guide the template imprint whatever the orientation of the obstacle. The usefulness of this articulated movement of the template around the end of the rule is to respond to the different angles of presentation of the obstacles to be coated. According to another particularly advantageous characteristic of the invention, the centering piece is mounted articulated about an axis perpendicular to the rule so as to orient the rule and the associated template, whatever the position of the marking of the coating in place where the centering piece is fixed.
La cinématique du système de l'instrument de traçage organisée par les mouvements d'articulation et de coulissement du gabarit et de la pièce de centrage par rapport à la règle, mouvements qui pourront être gelés par des organes de serrage appropriés, a pour objet d'appliquer un concept original de procédé de traçage qui consiste, suivant l'invention:The kinematics of the tracing instrument system organized by the movements of articulation and sliding of the template and the centering piece with respect to the ruler, movements which can be frozen by appropriate clamping members, is intended to '' apply an original concept of tracing process which consists, according to the invention:
- dans un premier temps, à positionner le gabarit autour de l'obstacle à enrober, - dans un deuxième temps, à ajuster les mouvements articulés et coulissants du gabarit et de la pièce de centrage de telle sorte que le croisillon de cette dernière puisse venir se loger et se caler dans l'intersection des joints entre les éléments du revêtement en place, située de préférence à proximité dudit obstacle,- firstly, to position the template around the obstacle to be coated, - secondly, to adjust the articulated and sliding movements of the template and the centering piece so that the crosspiece of the latter can come be lodged and wedged in the intersection of the joints between the elements of the coating in place, preferably located near said obstacle,
- dans un troisième temps, à serrer les organes de blocage pour empêcher les libres mouvements du gabarit et de la pièce de centrage,- thirdly, tighten the locking members to prevent free movement of the template and the centering piece,
- dans un quatrième temps, à dégager le gabarit et la pièce de centrage de l'obstacle et des joints du revêtement respectivement,- in a fourth step, to release the template and the centering piece from the obstacle and the seals of the coating respectively,
- dans un cinquième temps, à caler ladite pièce de centrage dans une autre intersection de joints du revêtement de telle sorte que le gabarit puisse se positionner au- dessus d'un élément dudit revêtement,- in a fifth step, to wedge said centering piece in another intersection of joints in the covering so that the template can be positioned above an element of said covering,
- dans un sixième et dernier temps, à disposer un élément de revêtement à découper juste au-dessus de l'élément posé et au-dessous du gabarit, afin de reproduire sur celui-ci l'empreinte du gabarit correspondant à celle de l'obstacle enrobé.- in a sixth and final step, to have a covering element to be cut just above the element placed and below the template, in order to reproduce thereon the imprint of the template corresponding to that of the coated obstacle.
Il résulte du procédé de traçage ci-dessus évoqué au moins trois principaux avantages de l'instrument de l'invention :It follows from the tracing process mentioned above that at least three main advantages of the instrument of the invention:
- d'abord, la précision du traçage grâce au repérage de la position de l'obstacle à enrober par rapport à un repère du revêtement, - ensuite, le maniement aisé de l'instrument car de conception simple et légère,- first, the precision of the tracing thanks to the location of the position of the obstacle to be coated relative to a marking of the coating, - then, the easy handling of the instrument because of its simple and light design,
- et enfin, l'adaptation à toutes dimensions et figures d'éléments de revêtement et à tout mode de pose (lignes en diagonales ou lignes orthonormées ).- and finally, the adaptation to all dimensions and figures of covering elements and to all installation methods (diagonal lines or orthonormal lines).
En outre, les pièces constitutives de cet instrument sont simples et particulièrement indiquées pour une fabrication en série industrielle. Les concepts fondamentaux de l'invention considérés comme nouveaux venant d'être exposés ci-dessus, le mode de réalisation préférée d'un instrument de traçage qui va être ci-dessous décrit et illustré, a pour objectif d'imager ces concepts fondamentaux ainsi que d'autres caractéristiques et avantages de l'invention, sans pour autant restreindre les variantes de construction possibles qui pourront facilement être mises en oeuvre par un homme de métier.In addition, the constituent parts of this instrument are simple and particularly suitable for industrial mass production. The fundamental concepts of the invention considered as new having just been exposed above, the preferred embodiment of a tracing instrument which will be described and illustrated below, aims to image these fundamental concepts as well than other characteristics and advantages of the invention, without limiting the possible construction variants which can easily be implemented by a person skilled in the art.
Cette description est annexée de dessins sur lesquels:This description is annexed to drawings in which:
La figure 1 est une vue en perspective partiellement éclatée d'un tel instrument de traçage.Figure 1 is a partially exploded perspective view of such a tracing instrument.
La figure 2 est une vue de dessus du dessin de la figure 1. La figure 3 illustre l'instrument des figures 1 et 2, en position de repérage.Figure 2 is a top view of the drawing of Figure 1. Figure 3 illustrates the instrument of Figures 1 and 2, in the locating position.
La figure 4 illustre l'instrument des figures 1 et 2, en position de traçage, une fois l'opération de repérage précédente finalisée.FIG. 4 illustrates the instrument of FIGS. 1 and 2, in the tracing position, once the previous locating operation has been finalized.
Tel qu'illustré sur le dessin de la figure 1, l'instrument de traçage référence I dans son ensemble s'adresse dans le cas présent spécifiquement à la pose d'éléments de revêtement de sols adoptant une figure carrée et appelés carreaux dans le contexte qui va suivre.As illustrated in the drawing of Figure 1, the tracing instrument reference I as a whole is intended in this case specifically for the installation of floor covering elements adopting a square shape and called tiles in the context who will follow.
Conformément aux dispositions principales de l'invention, cet instrument est constitué d'une règle de section carrée 100 coulissante (flèche à double sens C) dans une pièce de centrage 200 et portant à une extrémité 110, un gabarit de traçage 300.In accordance with the main provisions of the invention, this instrument consists of a sliding square section rule 100 (two-way arrow C) in a centering piece 200 and carrying at one end 110, a marking template 300.
Ce gabarit de traçage 300 est monté librement articulé (flèche à double sens RI) autour d'un axe 111 perpendiculaire à la règle 100.This layout template 300 is mounted freely articulated (two-way arrow RI) around an axis 111 perpendicular to the rule 100.
La pièce de centrage 200 est également montée articulée (flèche à double sens R2) autour d'un axe perpendiculaire à la règle 100 et parallèle à l'axe d'articulation 111 du gabarit 300. Les mouvements d'articulation de l'organe de centrage 200 et du gabarit 300 sont limités par des flasques circulaires respectivement 210 et 310. Ces flasques 210 et 310 sont percés chacun d'une lumière en forme de secteur, respectivement 211 et 311. Dans le secteur ouvert 211 sont guidées les tiges de deux organes de serrage manuels 212a, 212b permettant de bloquer la libre articulation du flasque 210 par rapport à la glissière 220 dudit organe de centrage, autorisant le coulissement C de la règle 100. Quant au gabarit 300, le secteur ouvert 311 est guidé autour de la tige d'un boulon coiffé d'un organe à serrage manuel 312 permettant de bloquer la rotation RI du flasque 310 par rapport à la règle 100.The centering piece 200 is also mounted articulated (two-way arrow R2) about an axis perpendicular to the rule 100 and parallel to the articulation axis 111 of the template 300. The articulation movements of the member centering 200 and template 300 are limited by circular flanges 210 and 310 respectively. These flanges 210 and 310 are each pierced with a sector-shaped light, respectively 211 and 311. In the open sector 211 are guided the rods of two manual clamping members 212a, 212b making it possible to block the free articulation of the flange 210 relative to the slide 220 of said centering member, allowing the sliding C of the rule 100. As for the gauge 300, the open sector 311 is guided around the rod of a bolt capped with a manual tightening member 312 making it possible to block the rotation RI of the flange 310 relative to the rule 100.
Le flasque 210 a pour objet de maintenir un croisillon 230 qui, animé d'un mouvement de coulissement C le long de la règle 100 et d'un mouvement de rotation R2 sur lui même, est destiné à venir se loger dans l'intersection des joints entre plusieurs carreaux, comme montré sur les dessins des figures 3 et 4. Le flasque 310 retient, quant à lui, un modèle d'empreintes 320 destinées à reproduire les contours d'obstacles standard fréquemment rencontrés. Le modèle 320 de l'instrument de traçage illustré reproduit deux empreintes d'huisseries de portes 321 et 322 disposées en tête-bêche et une réglette 323 pouvant s'adjoindre de manière réglable au modèle 320 en faisant office de fausse équerre, afin de reproduire les différents angles rencontrés.The purpose of the flange 210 is to maintain a cross-member 230 which, animated by a sliding movement C along the rule 100 and a rotary movement R2 on itself, is intended to be housed in the intersection of the joints between several tiles, as shown in the drawings of FIGS. 3 and 4. The flange 310 retains, for its part, a model of imprints 320 intended to reproduce the contours of standard obstacles frequently encountered. The model 320 of the tracing instrument illustrated reproduces two prints of door frames 321 and 322 arranged upside down and a strip 323 which can be added in an adjustable manner to the model 320 by acting as a false square, in order to reproduce the different angles encountered.
Comme mentionné un peu plus haut dans la description, les éléments constitutifs de l'instrument de traçage I sont simples et peuvent être réalisés à partir de pièces mécano- soudées pour un prix de revient faible.As mentioned a little above in the description, the constituent elements of the tracing instrument I are simple and can be produced from mechanically welded parts for a low cost price.
Les figures 3 et 4 ont pour objet d'illustrer le fonctionnement de l'instrument I mettant en application le procédé de traçage de l'invention permettant de reproduire sur un carreau à poser l'empreinte d'une huisserie de porte II qui se présenterait en première ligne d'un revêtement lu de carreaux déjà posés. Les carreaux de ce revêtement m sont affectés chacun d'un code d'identification utilisant un chiffre numérique pour symboliser le numéro d'ordre des colonnes et indicés d'une lettre alphabétique pour symboliser le numéro d'ordre des rangées. Les carreaux du revêtement III en place sont donc posés selon trois colonnes 1, 2 et 3 et alignés selon trois rangées a, b, c, de sorte que l'huisserie II se présente au futur emplacement du carreau 4c, c'est à dire à la troisième rangée de la quatrième colonne.FIGS. 3 and 4 are intended to illustrate the operation of the instrument I applying the tracing method of the invention making it possible to reproduce on a tile to lay the imprint of a door frame II which would appear on the first line of a read covering of already laid tiles. The tiles of this covering m are each assigned an identification code using a numerical number to symbolize the order number of the columns and subscribed with an alphabetical letter to symbolize the order number of the rows. The tiles of the covering III in place are therefore placed in three columns 1, 2 and 3 and aligned in three rows a, b, c, so that the door frame II is present at the future location of the tile 4c, that is to say in the third row of the fourth column.
Le procédé de traçage consiste donc en deux étapes successives.The tracing process therefore consists of two successive stages.
La première étape dite repérage, illustrée par le dessin de la figure 3, consiste à positionner l'instrument de traçage I de telle sorte que l'empreinte 321 du modèle 320 du gabarit 300 épouse les contours de l'huisserie II. Ensuite, la règle 100 est articulée (flèche RI) autour de son axe 111 de manière à disposer l'alignement de celle-ci au-dessus d'une intersection de joints d'éléments du revêtement EU. Le croisillon 230 est alors conduit (grâce à la conjugaison des deux mouvements de rotation R2 et de coulissement C du flasque 210) jusqu'à une intersection de joints où il est engagé pour être calé entre les carreaux 2b, 2c, 3b, 3c. Les organes de serrage appropriés 212a, 212b et 312 sont alors bloqués afin de geler les positions de la pièce de centrage 200 et du gabarit 300 sur la règle 100. L'opération de repérage des contours de l'huisserie II par rapport à ladite intersection de joints des carreaux 2b, 3b,3c, 2c formant repère, est alors terminée. Le carreleur dégage ensuite l'instrument I de son emprise autour de l'huisserie II et dans le revêtement m pour passer à l'étape suivante dite de traçage, telle qu' illustrée sur le dessin de la figure 4. Cette étape consiste alors à éloigner la pièce de centrage 200 d'au moins un carreau par rapport à l'huisserie ϋ, de manière à positionner le croisillon 230 dans l'intersection des joints des carreaux la, lb, 2a, 2b et le gabarit 300 au-dessus du carreau 3b du revêtement Lïï. Il suffit alors de glisser le carreau 4c à découper exactement au-dessus du carreau 3b et au-dessous du gabarit 300, afin de reproduire sur celui-ci le traçage de l'empreinte de l'huisserie II à enrober. Une fois l'empreinte sur le carreau 4c tracée, il ne reste plus qu'à découper les contours de ladite empreinte pour que le carreau 4c puisse être directement posé (comme le montre la flèche A) sans ajustage supplémentaire autour de l'huisserie II à son emplacement réservé de la quatrième colonne (4) à.The first so-called identification step, illustrated by the drawing in FIG. 3, consists in positioning the tracing instrument I so that the imprint 321 of the model 320 of the template 300 follows the contours of the frame II. Then, the rule 100 is articulated (arrow RI) around its axis 111 so as to have the alignment of the latter above an intersection of joints of elements of the coating EU. The spider 230 is then led (thanks to the combination of the two rotational movements R2 and sliding C of the flange 210) to an intersection of joints where it is engaged to be wedged between the tiles 2b, 2c, 3b, 3c. The appropriate clamping members 212a, 212b and 312 are then blocked in order to freeze the positions of the centering piece 200 and of the template 300 on the rule 100. The operation of locating the contours of the frame II with respect to said intersection of joints of the tiles 2b, 3b, 3c, 2c forming mark, is then completed. The tiler then releases the instrument I from its grip around the frame II and in the covering m to pass to the next step called tracing, as illustrated in the drawing of FIG. 4. This step then consists in move the centering piece 200 at least one tile away from the frame ϋ, so as to position the crosspiece 230 in the intersection of the joints of the tiles 1a, 1b, 2a, 2b and the template 300 above the tile 3b of the Lïï coating. It then suffices to slide the tile 4c to be cut exactly above the tile 3b and below the template 300, in order to reproduce thereon the tracing of the imprint of the frame II to be coated. Once the imprint on the tile 4c traced, it only remains to cut the contours of said imprint so that the tile 4c can be directly laid (as shown in arrow A) without additional adjustment around the frame II in its reserved place from the fourth column (4) to.
On comprend que l'instrument de traçage I, qui vient d'être ci-dessus décrit et représenté, l'a été en vue d'une divulgation plutôt que d'une limitation. Bien entendu, divers aménagements, modifications et améliorations pourront être apportés à l'exemple ci- dessus, sans pour autant sortir du cadre de l'invention pris dans ses aspects et dans son esprit les plus larges.It is understood that the tracing instrument I, which has just been described and shown above, was for the purpose of disclosure rather than limitation. Of course, various arrangements, modifications and improvements could be made to the above example, without however departing from the scope of the invention taken in its broadest aspects and spirit.
