Description

CORDEAU TRACEUR.TRACER CORD.

L'invention concerne un nouveau type de cordeau traceur, notamment pour charpentier. The invention relates to a new type of tracer line, in particular for carpenters.

Comme on le sait, un cordeau traceur est essentiellement constitué par un corps destiné à recevoir une bobine, actionnable depuis l'extérieur par une manivelle, et sur laquelle est enroulé un cordon souple à l'extrémité libre duquel est placé un crochet. Le corps est chargé de matière colorante et est fermé par un bouchon approprié, de manière à ce que en déroulant le cordon, celui-ci s'imprègne de matière colorante. Un opérateur place le crochet libre à un endroit approprié ; un second opérateur déroule le cordon, qui ainsi s'imprègne de matière, ce qui permet le traçage. Lorsque l'opération de traçage est terminée, il faut alors dégager le crochet, rembobiner la bobine pour réimprégner le cordon, notamment lorsqu'on est en bout de bobine. As is known, a tracer cord is essentially constituted by a body intended to receive a coil, actuated from the outside by a crank, and on which is wound a flexible cord at the free end of which a hook is placed. The body is loaded with coloring matter and is closed by an appropriate plug, so that by unrolling the bead, the latter is impregnated with coloring matter. An operator places the free hook in a suitable place; a second operator unrolls the cord, which soaks up the material, which allows tracing. When the tracing operation is finished, it is then necessary to disengage the hook, rewind the spool to reimpregnate the cord, especially when you are at the end of the spool.

Bien que largement répandu, ce dispositif présente des inconvénients notables, notamment en ce qui concerne la sécurité, puisque la mise en oeuvre nécessite des déplacements sur des pentes. En outre, cette mise en oeuvre est assez longue. Although widely used, this device has notable drawbacks, particularly with regard to safety, since the implementation requires travel on slopes. In addition, this implementation is quite long.

L'invention pallie ces inconvénients. Elle vise un cordon cordeau traceur perfectionné, de mise en oeuvre facile, notamment dans des conditions de travail difficiles. Ce cordeau traceur, constitué par un corps comprenant
. une bobine actionnable par une manivelle exté
rieure,
un cordon souple dont une extrémité est fixée à la
bobine,
une charge de matière colorante,
un orifice de sortie, à travers laquelle passe le
cordon imprégné de matière colorante, se caractérise en qu'il comprend, également un second corps sur la bobine duquel est fixée l'autre extrémité du cordon déroulé de la bobine du premier corps.
The invention overcomes these drawbacks. It is aimed at an improved tracer cord, easy to apply, especially in difficult working conditions. This tracer line, consisting of a body comprising
. a coil actuated by an external crank
laughter,
a flexible cord, one end of which is attached to the
coil,
a charge of coloring matter,
an outlet, through which the
bead impregnated with coloring matter, is characterized in that it also comprises a second body on the spool of which is fixed the other end of the bead unwound from the spool of the first body.

En d'autres termes, le cordeau traceur perfectionné caractéristique de l'invention se compose de deux corps symétriques, dont les bobines sont reliées par un seul et même cordon, que l'on transfère alternativement d'une bobine à l'autre. In other words, the improved tracer line characteristic of the invention consists of two symmetrical bodies, the coils of which are connected by a single cord, which is transferred alternately from one coil to the other.

En pratique, le premier et le deuxième corps sont identiques et de forme variée ronde : ovoïde, hexagonale. In practice, the first and second bodies are identical and of various round shape: ovoid, hexagonal.

Le cordon traceur lui-même peut être réalisé en toute matière appropriée, par exemple en coton tressé. Avantageusement, l'invention permet de mettre en oeuvre des bobines de plus grande longueur, par exemple de quarante mètres, voire plus.The tracer cord itself can be made of any suitable material, for example braided cotton. Advantageously, the invention makes it possible to use coils of greater length, for example of forty meters, or even more.

La manière dont l'invention peut être réalisée et les avantages qui en découlent, ressortiront mieux de l'exemple de réalisation qui suit, à l'appui des figures annexées. The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the embodiment which follows, with the support of the appended figures.

La figure 1 est une représentation en vue perspective sommaire d'un dispositif conforme à l'invention. Figure 1 is a summary perspective view of a device according to the invention.

La figure 2 montre en coupe un corps caractéristique de l'invention. Figure 2 shows in section a body characteristic of the invention.

La figure 3 est une vue de détail d'une manivelle d'actionnement de la bobine. Figure 3 is a detailed view of a crank for actuating the coil.

Le cordeau traceur selon l'invention se compose de deux corps, respectivement un premier corps désigné par la référence (1) et d'un second corps désigné par la référence (10), reliés entre eux par un seul et même cordon tressé désigné par la référence générale (20), par exemple une tresse de 1,5 mm de diamètre en polyester/ coton. Dans une forme pratique, le cordon (20) a quarante mètres de longueur, soit plus de la moitié des cordons actuels. Chaque corps (1,10) se compose de deux demicoquilles, respectivement (2) et (3) emboitées, de forme appropriée : ronde, ovoïde, hexagonale, en tout matériau adapté, tel que matière plastique moulée, métal, etc.. The tracer cord according to the invention consists of two bodies, respectively a first body designated by the reference (1) and a second body designated by the reference (10), interconnected by a single braided cord designated by the general reference (20), for example a braid 1.5 mm in diameter in polyester / cotton. In a practical form, the cord (20) is forty meters in length, more than half of the current cords. Each body (1.10) consists of two half-shells, respectively (2) and (3) fitted together, of appropriate shape: round, ovoid, hexagonal, in any suitable material, such as molded plastic, metal, etc.

Chaque corps (1,10) et plus précisément la coquille inférieure (3), reçoit une bobine (4) sur laquelle est enroulé le cordon (20), fixé à chacune de ses extrémités (21) aux deux bobines (4) des deux corps (1) et (10).Each body (1,10) and more precisely the lower shell (3), receives a coil (4) on which is wound the cord (20), fixed at each of its ends (21) to the two coils (4) of the two body (1) and (10).

De manière connue, chaque bobine (4) présente une ouverture centrale en forme de carré (5) qui s'emboite sur une forme mâle carrée correspondante (6) en matière plastique, logée dans un orifice prévu à cet effet, contre lequel vient s'appuyer une rondelle (7). De manière connue, la portion extérieure (8) de cet axe (6) reçoit une manivelle articulée (9,9') actionnable par un axe (11). Les deux coquilles (2,3) sont rassemblées par tout moyen connu, tel que clipsage, vis, etc. In known manner, each coil (4) has a central square opening (5) which fits on a corresponding square male form (6) of plastic material, housed in a hole provided for this purpose, against which s '' press a washer (7). In known manner, the outer portion (8) of this axis (6) receives an articulated crank (9,9 ') actuable by an axis (11). The two shells (2,3) are assembled by any known means, such as clipping, screws, etc.

La demi-coquille inférieure (3) présente un col (15,16) de sortie, fermé par un bouchon (17,18) rempli de manière connue de mousse, par exemple en polyuréthanne, fendu selon un rayon pour permettre au cordon (20) qui défile en passant sur un renvoi (19), de s'imprégner de la matière collante non référencée dans laquelle baigne la bobine. Avantageusement, l'orifice du bouchon (17,18) est protégé de l'usure générée par le coulissement du cordon (20) par un embout cylindrique en acier, facilitant ainsi le glissement dudit cordon au passage du bouchon.  The lower half-shell (3) has an outlet neck (15, 16), closed by a plug (17, 18) filled in a known manner with foam, for example made of polyurethane, split along a radius to allow the cord (20 ) which passes while passing on a return (19), to impregnate the sticky material not referenced in which the coil bathes. Advantageously, the orifice of the plug (17,18) is protected from wear and tear generated by the sliding of the cord (20) by a cylindrical steel tip, thus facilitating the sliding of said cord when the plug passes.

Comme déjà dit, selon la caractéristique de l'invention, le cordon traceur (20) est relié à une extrémité (21) à la bobine (4) du premier corps (1), et à son autre extrémité non représentée à la bobine du second corps (10), qui est en tous points symétrique au premier corps (1).  As already said, according to the characteristic of the invention, the tracer cord (20) is connected at one end (21) to the coil (4) of the first body (1), and at its other end not shown to the coil of the second body (10), which is in all points symmetrical to the first body (1).

La mise en oeuvre de ce nouveau cordeau traceur est simplifiée. En effet, il suffit qu'un premier opérateur prenne le premier corps et un autre opérateur le second. The implementation of this new tracer line is simplified. Indeed, it suffices that a first operator takes the first body and another operator the second.

Ces deux opérateurs se déplacent de proche en proche.These two operators move step by step.

Lorsque sensiblement toute la longueur du cordon a été déroulée, il suffit de rembobiner ce cordon sur l'autre corps pour que le cordon soit immédiatement prêt à nouveau à l'emploi.When substantially the entire length of the cord has been unwound, it suffices to rewind this cord on the other body so that the cord is immediately ready for use again.

Cette disposition originale permet un gain de temps appréciable et surtout, améliore la sécurité des opérateurs travaillant sur des toits, spécialement en limitant les déplacements sur des pentes. Il peut être ainsi utilisé avec succès dans des conditions de travail difficiles.  This original arrangement saves appreciable time and above all, improves the safety of operators working on roofs, especially by limiting travel on slopes. It can thus be successfully used in difficult working conditions.
