Description

La présente invention concerne de façon générale un dispositif d'assistance à la pose de lambris sur des tasseaux.The present invention relates generally to a assistance device for installing paneling on cleats.

Plus précisément, l'invention concerne un dispositif d'assistance à la pose, sur un tasseau de largeur déterminée, de lambris à disposer transversalement à ce tasseau, ce dispositif comprenant des organes de fixation pour se fixer sur le tasseau, une tige sélectivement entraínée en translation par rapport aux organes de fixation, parallèlement au tasseau, un poussoir fixé à une extrémité de la tige, et des organes d'entraínement, solidaires des organes de fixation, pour entraíner la tige suivant un axe longitudinal de la tige, dans un sens d'avancement pour lequel le poussoir la précède.More specifically, the invention relates to a device installation assistance, on a wide strip paneling to be placed transversely to this cleat, this device comprising fixing to fix on the cleat, a rod selectively driven in translation relative to fasteners, parallel to the cleat, a pusher attached to one end of the rod, and of the members drive, integral with the fixing members, for drive the rod along a longitudinal axis of the rod, in a direction of travel for which the pusher precedes it.

Des dispositifs de ce type sont bien connus dans l'art antérieur, comme en témoignent notamment les brevets US - 1 618 896, US - 2 717 144, US - 3 524 623, US - 4 620 691, et FR - 2 701 883.Devices of this type are well known in the art earlier, as evidenced in particular by patents US - 1,618,896, US - 2,717,144, US - 3,524,623, US - 4 620 691, and FR - 2 701 883.

Le problème essentiel que soulève la pose de lambris réside dans la difficulté d'appliquer aux lambris, en deux points espacés de leur longueur, des forces équilibrées pour garantir le parallélisme des lambris posés, cette difficulté étant pratiquement insurmontable lorsque la pose est effectuée par une seule personne.The essential problem raised by the installation of paneling lies in the difficulty of applying to paneling, in two points spaced apart in length, forces balanced to guarantee the parallelism of the paneling posed, this difficulty being practically insurmountable when the installation is carried out by a single person.

Certains des dispositifs connus ne visent cependant pas à résoudre ce problème, mais seulement à permettre l'application, sur les lambris en cours de pose, d'une force relativement élevée moyennant un effort physique relativement modéré.Some of the known devices do not, however, aim to solve this problem but only to allow the application, on the paneling during installation, of a relatively high force with physical effort relatively moderate.

Par ailleurs, bien que le dispositif par exemple décrit dans le brevet US - 3 524 623 résolve ce problème, ce brevet préconise l'emploi, en tant qu'organes de fixation, de clous destinés à pénétrer dans le bois du tasseau.Furthermore, although the device for example described in US Patent 3,524,623 solves this problem, this patent recommends the use, as organs of fixing, nails intended to penetrate into the wood of the cleat.

Pour faciliter la pénétration des clous dans le bois, ces derniers sont inclinés suivant une direction inverse du sens d'avancement du poussoir, de sorte qu'ils s'impriment en principe dans le bois du tasseau lorsque la force appliquée sur le lambris en cours de pose dépasse la résistance du bois à l'enfoncement de ces clous.To facilitate the penetration of nails into the wood, these are tilted in an opposite direction the direction of advancement of the pusher, so that they print in principle in the cleat wood when the force applied to the paneling during installation exceeds the resistance of the wood to the penetration of these nails.

L'expérience montre cependant que si le tasseau est constitué d'un bois trop tendre, les clous ont tendance à déchirer le bois du tasseau avant même que la force appliquée sur le lambris en cours de pose soit suffisante, et que si le tasseau est constitué d'un bois trop dur, l'extraction des clous est particulièrement malcommode.Experience shows, however, that if the cleat is made of too soft wood, nails tend to tear the wood of the cleat even before the force applied to the paneling during installation either sufficient, and that if the cleat consists of a wood too hard, extracting the nails is particularly inconvenient.

Dans ce contexte, l'invention vise notamment à proposer un dispositif d'assistance à la pose de lambris qui s'affranchisse de ce compromis, tout en présentant une grande facilité d'utilisation.In this context, the invention aims in particular to propose a device to assist with the installation of paneling which frees itself from this compromise, while presenting a great ease of use.

A cette fin, le dispositif de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que les organes de fixation comprennent un étrier formant étau, équipé d'une cale vissable pour adapter une dimension transversale de l'étrier à la largeur du tasseau, et d'une sauterelle pour fixer sélectivement l'étrier sur le tasseau.To this end, the device of the invention, moreover conforms to the generic definition given by the preamble above, is essentially characterized by what the fasteners include a stirrup forming a vice, equipped with a screwable shim to adapt a transverse dimension of the stirrup to the width of the cleat, and a grasshopper to selectively fix the stirrup on the cleat.

Selon un mode de réalisation préféré de l'invention, les organes d'entraínement comprennent une pince essentiellement formée d'un premier et d'un second leviers sensiblement perpendiculaires à la tige et respectivement fixe et pivotant par rapport à l'étrier, un cliquet d'entraínement monté basculant autour d'un premier axe transversal fixé au second levier et transmettant à la tige, dans le sens d'avancement, un mouvement de translation lié au mouvement de pivotement du second levier, et un cliquet de retenue, monté basculant autour d'un second axe transversal fixe par rapport à l'étrier, pour interdire à la tige un mouvement dans un sens inverse du sens d'avancement.According to a preferred embodiment of the invention, the drives include a clamp essentially formed of a first and a second levers substantially perpendicular to the rod and respectively fixed and pivoting with respect to the stirrup, a mounted ratchet rocking around a first transverse axis fixed to the second lever and transmitting to the rod, in the direction of travel, a translational movement linked to the pivoting movement of the second lever, and a retaining pawl, mounted tilting around a second fixed transverse axis by relative to the stirrup, to prevent the rod a movement in the opposite direction to the direction of travel.

Dans ce cas, le premier levier est de préférence conformé en chape et le second levier est monté pivotant autour d'un troisième axe transversal, le premier levier supportant alors les second et troisième axes transversaux.In this case, the first lever is preferably shaped like a yoke and the second lever is pivotally mounted around a third transverse axis, the first lever then supporting the second and third axes transverse.

La tige, qui peut être crantée, présente par exemple une surface externe sensiblement cylindrique, n'est avantageusement crantée que sur une plage angulairement limitée de sa surface externe, et présente éventuellement un crochet permettant de l'entraíner facilement en rotation autour de son axe longitudinal, cette tige pouvant ainsi être débrayée des cliquets d'entraínement et de retenue.The rod, which can be notched, has for example a substantially cylindrical outer surface, is advantageously notched only on a beach angularly limited of its external surface, and presents possibly a hook to train it easily rotated around its longitudinal axis, this rod can thus be disengaged from the pawls training and restraint.

L'étrier peut présenter une base reliant des première et seconde branches latérales, la première branche latérale portant la sauterelle.The stirrup can have a base connecting first and second lateral branches, the first lateral branch carrying the grasshopper.

Par exemple, la sauterelle présente un axe de poussée qui traverse la première branche latérale de l'étrier, alors que la cale vissable est portée par l'axe de poussée de la sauterelle, la deuxième branche de l'étrier portant une ou plusieurs griffes tournées vers la première branche. For example, the grasshopper has a thrust axis which crosses the first lateral branch of the stirrup, while the screwable shim is carried by the axis of grasshopper thrust, the second branch of the stirrup carrying one or more claws facing the first branch.

Dans un mode de réalisation préféré de l'invention, l'étrier, la pince, et le poussoir sont constitués de flans métalliques découpés et pliés, et une extrémité du premier levier s'élargit pour former une platine qui est rendue solidaire d'une face externe de la base de l'étrier.In a preferred embodiment of the invention, the caliper, the clamp, and the pusher consist of cut and folded metal blanks, and one end of the first lever widens to form a plate which is made integral with an external face of the base of stirrup.

Le poussoir est de préférence conçu pour former, au bout de la tige, une pelle renversée propre à assurer, si nécessaire, le maintien d'un gabarit.The pusher is preferably designed to form, at the end of the rod, an overturned shovel suitable for ensuring, if necessary, maintaining a template.

Le poussoir peut en outre être monté de façon amovible sur l'extrémité de la tige pour être interchangeable, ce poussoir pouvant alors aussi prendre la forme d'une patte de guidage qui s'étend au moins partiellement dans un plan contenant l'axe longitudinal de la tige.The pusher can also be removably mounted on the end of the rod to be interchangeable, this push button can then also take the form of a guide tab which extends at least partially into a plane containing the longitudinal axis of the rod.

Le poussoir présente par exemple des découpes délimitant des bandes transversales dont certaines au moins sont disposées de part et d'autre de la tige et dont l'une vient buter sur l'extrémité de la tige.The pusher has, for example, cutouts delimiting transverse bands, at least some of which are arranged on either side of the rod and one of which abuts on the end of the rod.

Enfin, l'extrémité de la tige peut présenter un épaulement prenant place dans l'une des découpes et déformant élastiquement l'une au moins des bandes transversales lorsque le poussoir est enfilé sur la tige.Finally, the end of the rod may have a shoulder taking place in one of the cutouts and elastically deforming at least one of the bands transverse when the pusher is threaded on the rod.

D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence aux dessins annexés.Other characteristics and advantages of the invention will emerge clearly from the description which is made below, for information only and in no way limiting, with reference to the accompanying drawings.

Dans ces derniers, la figure 1 est une vue en perspective générale d'un dispositif conforme à l'invention, en cours d'utilisation, la distance entre le gabarit et le lambris à poser, ainsi que la distance entre le lambris à poser et les lambris déjà posés, ayant été dilatées pour permettre une meilleure compréhension de la figure.In these, Figure 1 is a view in general perspective of a device conforming to the invention, in use, the distance between the template and paneling to be installed, as well as the distance between the paneling to be installed and the paneling already installed, having been dilated to allow better understanding of the figure.

La figure 2 est une vue en perspective éclatée du dispositif représenté à la figure 1.Figure 2 is an exploded perspective view of the device shown in Figure 1.

La figure 3 est une vue en perspective du dispositif représenté à la figure 2, après assemblage.Figure 3 is a perspective view of the device shown in Figure 2, after assembly.

Et la figure 4 est une vue de dessus de la tige équipée d'un poussoir d'un autre type.And Figure 4 is a top view of the equipped rod of a pusher of another type.

Comme le montre le mieux la figure 1, l'invention concerne un dispositif destiné à faciliter la pose de lambris 2 sur des tasseaux 1, les lambris étant disposés transversalement par rapport aux tasseaux.As best shown in Figure 1, the invention relates to a device intended to facilitate the installation of paneling 2 on battens 1, the paneling being arranged transversely to the cleats.

Ce dispositif comprend, de façon générale, des organes de fixation 3 permettant de le fixer sur un tasseau 1, une tige 4, un poussoir 5 fixé, de préférence de façon amovible, à une extrémité 40 de la tige 4, et des organes d'entraínement 6 pour entraíner la tige 4 suivant un axe longitudinal X (figure 3) et dans un sens d'avancement A.This device generally comprises organs fixing 3 allowing it to be fixed on a cleat 1, a rod 4, a pusher 5 fixed, preferably so removable, at one end 40 of the rod 4, and drive members 6 for driving the rod 4 along a longitudinal axis X (Figure 3) and in one direction of advancement A.

Les organes d'entraínement 6 sont solidaires des organes de fixation 3, qui sont eux-mêmes solidaires, en fonctionnement, du tasseau 1, la tige étant entraínée en translation le long de ce tasseau 1.The drive members 6 are integral with the bodies fixing 3, which are themselves integral, in operation, the cleat 1, the rod being driven in translation along this cleat 1.

Selon l'invention, les organes de fixation 3 comprennent un étrier 30 formant étau (figures 2 et 3), équipé d'une cale vissable 31 pour adapter la dimension transversale de l'étrier à la largeur L du tasseau 1, et d'une sauterelle 32 permettant de fixer rapidement l'étrier 30 sur le tasseau 1 et de l'en retirer tout aussi rapidement.According to the invention, the organs of fixing 3 include a stirrup 30 forming a vice (Figures 2 and 3), fitted with a screwable shim 31 for adapt the transverse dimension of the stirrup to the width L of the cleat 1, and of a grasshopper 32 allowing to quickly fix the bracket 30 on the cleat 1 and remove it just as quickly.

Par "sauterelle" on entend ici tout mécanisme de verrouillage à came ou levier, fonctionnant sur le principe universellement connu du point mort dépassé, encore connu sous le nom du principe de "genouillère".By "grasshopper" is meant here any mechanism of cam or lever lock, operating on the universally known principle of dead center exceeded, also known as the "knee brace" principle.

Par ailleurs, les organes d'entraínement 6 comprennent essentiellement une pince 60, un cliquet d'entraínement 63, et un cliquet de retenue 64, la pince étant principalement formée de deux leviers 61, 62 disposés pratiquement en équerre par rapport à la tige 4 et dont le premier, 61, est monté fixe par rapport à l'étrier 30.In addition, the drive members 6 include essentially a clamp 60, a drive pawl 63, and a retaining pawl 64, the clamp being mainly formed by two levers 61, 62 arranged practically square to rod 4 and of which the first, 61, is mounted fixed relative to the stirrup 30.

L'étrier 30, la pince 60, et le poussoir 5 sont de préférence constitués de flans métalliques découpés et pliés.The stirrup 30, the clamp 60, and the pusher 5 are of preferably made of cut metal blanks and folded.

Lorsque tel est le cas, il est aisé de prévoir que le levier fixe 61 soit conformé en chape et qu'il présente une extrémité qui s'élargisse, grâce à un repli, pour former une platine 610.When this is the case, it is easy to predict that the fixed lever 61 is shaped like a yoke and has one end which widens, thanks to a fold, for form a plate 610.

La platine 610 peut elle-même être rendue solidaire de la face externe de la base 300 de l'étrier 30, par exemple au moyen de vis telles que 611, et d'ergots tels que 612 engagés dans des lumières telles que 301 de la base 300 de l'étrier 30.The plate 610 can itself be made integral with the outer face of the base 300 of the stirrup 30, by example by means of screws such as 611, and lugs such that 612 engaged in lights such as 301 of the base 300 of stirrup 30.

Le second levier 62 peut ainsi être monté pivotant autour d'un axe transversal 623 qui est supporté par la chape que constitue le levier fixe 61, un ressort hélicoïdal 600 étant enroulé sur cet axe pour écarter élastiquement le levier 62 du levier fixe 61 et appuyer le levier 62 contre une butée transversale 69. The second lever 62 can thus be pivotally mounted around a transverse axis 623 which is supported by the clevis formed by the fixed lever 61, a spring helical 600 being wound on this axis to separate resiliently lever 62 of fixed lever 61 and press the lever 62 against a transverse stop 69.

Comme le montre bien la figure 3, la tige 4 est de préférence crantée, mais seulement sur une plage angulairement limitée de sa surface externe, cette surface étant par ailleurs essentiellement cylindrique.As shown in Figure 3, the rod 4 is notched preference, but only on a beach angularly limited from its external surface, this surface also being essentially cylindrical.

Le cliquet d'entraínement 63 est monté basculant autour d'un axe transversal 631 fixé à une extrémité du levier 62 pour transmettre à la tige 4, dans le sens d'avancement A, un mouvement de translation lié au mouvement de pivotement du second levier 62 autour de l'axe 623.The drive pawl 63 is mounted tilting around a transverse axis 631 fixed to one end of the lever 62 to transmit to the rod 4, in the direction advancement A, a translational movement related to pivoting movement of the second lever 62 around axis 623.

Le cliquet de retenue 64 est monté basculant autour d'un axe transversal 642 supporté par la chape que constitue le levier fixe 61, et a pour fonction d'interdire à la tige 4 tout mouvement dans un sens inverse du sens d'avancement A.The retaining pawl 64 is mounted to pivot around a transverse axis 642 supported by the yoke that constitutes the fixed lever 61, and has the function of prohibiting the rod 4 any movement in opposite direction of advancement A.

Chacun des cliquets 63 et 64 est élastiquement sollicité vers la tige 4 grâce à un ressort hélicoïdal approprié, par exemple enroulé sur l'axe de ce cliquet.Each of the pawls 63 and 64 is elastically stressed towards the rod 4 by means of a suitable helical spring, for example wound on the axis of this ratchet.

La tige 4 est guidée en translation contre la face externe de la base 300 de l'étrier 30, ou à son voisinage, du côté de l'extrémité du levier fixe 61 en forme de platine, et de manière à pouvoir être entraínée en rotation autour de son axe longitudinal X.The rod 4 is guided in translation against the face external of the base 300 of the stirrup 30, or to its near the end of the fixed lever 61 in form of platinum, and so that it can be rotated around its longitudinal axis X.

Cette tige 4 est par ailleurs de préférence conformée en crochet à son extrémité 41 distante du poussoir 5, de manière à faciliter son entraínement en rotation autour de l'axe X, grâce auquel le crantage 42 de la tige échappe aux cliquets 63 et 64, et grâce auquel la tige 4 peut donc être librement déplacée par rapport à l'étrier 30. This rod 4 is also preferably shaped as hook at its end 41 distant from pusher 5, so as to facilitate its training in rotation around of the X axis, thanks to which the notch 42 of the rod escapes the pawls 63 and 64, and thanks to which the rod 4 can therefore be freely moved relative to the bracket 30.

Le poussoir 5 monté à l'extrémité 40 de la tige 4 peut adopter la forme d'une pelle renversée, de manière à pouvoir, si nécessaire, maintenir un gabarit 7 dont la partie avant 70 est adaptée au profil du lambris, dans le cas où ce lambris est orienté d'une façon telle qu'une pression directement exercée sur lui par le poussoir risquerait de l'endommager.The pusher 5 mounted at the end 40 of the rod 4 can adopt the shape of an overturned shovel, so that ability, if necessary, to maintain a template 7 whose front part 70 is adapted to the profile of the paneling, in the case where this paneling is oriented in such a way that pressure directly exerted on him by the pushing may damage it.

L'étrier 30 adopte globalement un profil en "U", formé de deux branches latérales 301, 302 reliées l'une à l'autre par la base 300 de cet étrier 30.The stirrup 30 generally adopts a U-shaped profile, formed of two lateral branches 301, 302 connected one to the other by the base 300 of this stirrup 30.

La première branche 301 présente par exemple une oreille 303 sur laquelle est articulée la sauterelle 32.The first branch 301 has for example an ear 303 on which the grasshopper 32 is articulated.

La sauterelle 32 présente par ailleurs un axe de poussée 320 qui traverse la première branche latérale 301 de l'étrier, et qui peut être fileté pour porter un écrou propre à constituer la cale vissable 31.The grasshopper 32 also has a thrust axis 320 which crosses the first lateral branch 301 of the bracket, which can be threaded to carry a nut suitable for constituting the screwable block 31.

Pour parfaire le maintien de l'étrier 30 sur le tasseau 1, l'autre branche 302 de l'étrier porte avantageusement deux griffes, telles que 304, qui sont orientées suivant une direction transversale et qui pointent vers la première branche 301.To perfect the retention of the stirrup 30 on the cleat 1, the other branch 302 of the stirrup advantageously carries two claws, such as 304, which are oriented along a transverse direction and which point towards the first branch 301.

Bien que le poussoir 5 puisse être riveté sur l'extrémité 40 de la tige 4, il est de préférence monté de façon amovible sur cette tige, éventuellement au moyen d'une vis.Although pusher 5 can be riveted on the end 40 of the rod 4, it is preferably mounted removably on this rod, possibly at by means of a screw.

En outre, comme le montre la figure 4, ce poussoir peut adopter diverses formes, et notamment celle d'une patte de guidage 50 qui s'étend au moins partiellement dans un plan contenant l'axe longitudinal X de la tige, et qui s'élargit à distance de l'extrémité 40 de cette tige. In addition, as shown in Figure 4, this pusher can adopt various forms, including that of a paw guide 50 which extends at least partially in a plane containing the longitudinal axis X of the rod, and which widens at a distance from the end 40 of this rod.

Comme le montre par ailleurs la figure 4, le poussoir 5 peut présenter des découpes, telles que 51, 53 et 55, qui délimitent des bandes transversales, telles que 52, 54, 56, 58, servant au montage amovible du poussoir 5 sur la tige 4.As FIG. 4 also shows, the pusher 5 may have cutouts, such as 51, 53 and 55, which delimit transverse bands, such as 52, 54, 56, 58, used for removable mounting of the pusher 5 on the rod 4.

Plus précisément, certaines de ces découpes, telles que 52, 54 et 56, sont disposées de part et d'autre de la tige 4, et l'une de ces découpes, telle que 58, vient buter sur l'extrémité 40 de la tige 4.More specifically, some of these cutouts, such as 52, 54 and 56, are arranged on either side of the rod 4, and one of these cutouts, such as 58, comes abut on the end 40 of the rod 4.

De préférence, l'extrémité 40 de la tige 4 présente un relief, tel qu'un épaulement 400, qui prend place dans l'une des découpes 55, et qui déforme élastiquement l'une au moins des bandes transversales, telle que 56, lorsque ce poussoir 5 est enfilé sur la tige 4.Preferably, the end 40 of the rod 4 has a relief, such as a shoulder 400, which takes place in one of the cutouts 55, and which elastically deforms at least one of the transverse bands, such as 56, when this pusher 5 is threaded on the rod 4.

On notera enfin que l'invention n'est pas limitée aux modes de réalisation décrits.Finally, it should be noted that the invention is not limited to described embodiments.

En effet, il est possible de doter les moyens de fixation 3 de moyens de réglage de la longueur de la cale vissable 31 de manière à adapter cette dernière à la largeur du tasseau 1. Par exemple, ces moyens se présentent sous la forme d'un jeu de vis adaptées chacune pour le montage de la cale vissable 31, ces vis ayant des longueurs spécifiques et étant choisies chacune en fonction de la largeur de tasseaux susceptibles de recevoir le dispositif d'assistance selon l'invention.Indeed, it is possible to provide the means to fixing 3 of means for adjusting the length of the screwable shim 31 so as to adapt the latter to the width of the cleat 1. For example, these means in the form of a set of suitable screws each for mounting the screwable shim 31, these screws having specific lengths and being chosen each according to the width of the battens likely to receive the assistance device according to the invention.

Par ailleurs, il est également possible de prévoir, sur la paroi constitutive du poussoir 5 des orifices (non représentés) permettant la fixation, par exemple par vissage, d'une cale martyre par laquelle le poussoir 5 exerce un effort sur les lambris 7. In addition, it is also possible to provide, on the wall constituting the pusher 5 of the orifices (not shown) allowing attachment, for example by screwing, of a martyr wedge by which the pusher 5 exerts an effort on the paneling 7.

Enfin, de préférence, on adapte la forme du poussoir 5 au type de lambris à monter, à savoir soit à ténon soit à mortaise.Finally, preferably, the shape of the pusher 5 is adapted. the type of paneling to be fitted, namely either tenon or mortise.
