Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention se rattache au secteur technique des appareils de levage et de manutention utilisés dans le bâtiment pour la présentation de plaques en tous matériaux pour constituer des faux plafonds, ou pour l'aménagement sous rampant et sur cloisons.The invention relates to the technical sector of lifting and handling devices used in the building for the presentation of plates of any materials to form false ceilings, or for the development under crawling and partitions.

ART ANTÉRIEURPRIOR ART

Le demandeur a développé depuis de nombreuses années des appareils de manutention de plaques ou panneaux en plâtre ou autres matériaux de forme rectangulaire et de poids et dimensions importants, pouvant aller jusqu'à plus de trois mètres en longueurThe applicant has for many years developed handling devices for plates or panels of plaster or other materials of rectangular shape and of significant weight and dimensions, up to more than three meters in length.

Les panneaux, grâce aux appareils du type précité comprenant un mécanisme à treuil et par des moyens d'orientation, sont présentés à l'horizontal pour être apposés au plafond à recouvrir. Des appareils de ce type sont décrits dans les documents de brevets FR 2 875 832 , et FR 2 946 376 , dont le Demandeur est Titulaire.The panels, with the devices of the aforementioned type comprising a winch mechanism and by means of orientation, are presented horizontally to be affixed to the ceiling to be covered. Devices of this type are described in the patent documents FR 2,875,832 , and FR 2 946 376 , of which the Applicant is the Holder.

Plus particulièrement, le document FR 2 875 832 , prévoit la mise en oeuvre d'un profilé support fixe déporté par rapport à la partie mât, en recevant en extrémité un moyen d'articulation du dispositif support de plaque ou panneau. Le dispositif inclue une base support susceptible de basculer d'une position à l'horizontale en étant verrouillée, à une position à la verticale, la position intermédiaire correspondant au chargement du porte panneau ou plaque, ou à la pose sur plan incliné appelé « sous rampant ».More particularly, the document FR 2,875,832 , provides for the implementation of a fixed support profile offset relative to the mast portion, receiving at the end a hinge means of the plate or panel support device. The device includes a support base capable of swinging from a horizontal position while being locked, to a vertical position, the intermediate position corresponding to the loading of the door panel or plate, or to the laying on an inclined plane called "under crawling ".

Le document FR 2 946 376 prévoit la mise en oeuvre d'un dispositif porte plaque de matériau pour appareil de levage et de manutention du type comprenant un mât à l'extrémité duquel est disposé un moyen support. Le moyen support reçoit, de manière articulée, une ossature support porte plaque qui comprend un socle support profilé en U. Le socle reçoit entre ses ailes deux axes d'articulation. Un premier axe assure l'articulation de la base support sur laquelle est positionnée l'ossature support porte plaque ou porte panneaux, et un second axe sur lequel est disposé, libre en pivotement, un cliquet de verrouillage basculant de par sa répartition de masse. Un cliquet présente une tête formant crochet pour coopérer et s'ajuster autour d'un axe formant doigt disposé en débordement de la base support. Une face arrière droite formant butée d'arrêt et un bras de levier et de manoeuvre présente, en extrémité, une forme de balourd.The document FR 2 946 376 provides for the implementation of a plate plate material device for lifting and handling apparatus of the type comprising a mast at the end of which is disposed a support means. The support means receives, in an articulated manner, a plate support frame which comprises a U-shaped support base. The base receives between its wings two axes of articulation. A first axis ensures the articulation of the support base on which is positioned the support frame plate holder or panel door, and a second axis on which is freely pivotally disposed, a rocking latch pawl by its mass distribution. A pawl has a hook head to cooperate and fit around a finger axis disposed overflow of the support base. A right rear face forming a stop and a lever arm and maneuver has, at the end, a form of unbalance.

Les appareils faisant l'objet des brevets précités sont largement exploités par le demandeur avec un grand succès commercial.The devices covered by the aforementioned patents are widely used by the applicant with great commercial success.

Si le premier moyen décrit et qui se réfère au brevet FR 2 875 832 , permet la pose de plaque dans les trois positions, horizontale, sous-rampant et verticale, la mise en oeuvre de cet appareil reste néanmoins coûteuse à réaliser en fabrication et en assemblage, notamment du fait de l'utilisation de profilés spéciaux.If the first means described and which refers to the patent FR 2,875,832 , allows the installation of plate in the three positions, horizontal, sub-crawling and vertical, the implementation of this device is nevertheless expensive to achieve in manufacturing and assembly, especially because of the use of special profiles.

Concernant le dispositif décrit dans le document FR 2 946 376 , celui-ci permet la pose de plaque ou panneau dans seulement deux positions, horizontale et sous-rampant, mais pas à la verticale.Concerning the device described in the document FR 2 946 376 , it allows the installation of plate or panel in only two positions, horizontal and sub-crawling, but not vertically.

De plus, un autre inconvénient résulte du fait que l'utilisateur d'un tel appareil doit modifier la position du support de plaque sur le dispositif d'orientation des plaques et panneaux pour passer de la pose de plaque à l'horizontale, à celle de sous-rampant ou verticale.In addition, another disadvantage results from the fact that the user of such a device must change the position of the plate support on the orientation device of the plates and panels to move from laying the plate horizontally, to that sub-crawling or vertical.

En effet, lorsque l'opérateur souhaite passer de la pose horizontale à celle inclinée dite «sous-rampant », celui-ci doit désengager l'ossature support des plaques du dispositif d'orientation des plaques ou panneaux, afin de lui faire subir une rotation de 90° avant de l'engager à nouveau sur le dispositif d'orientation. Cette manipulation est lourde et contraignante.Indeed, when the operator wishes to move from the horizontal to the so-called "sub-crawling" inclined, it must disengage the support frame plates of the orientation device of the plates or panels, to make it undergo a 90 ° rotation before engaging it again on the orientation device. This manipulation is heavy and restrictive.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

La démarche du demandeur a été de rechercher comment modifier l'appareil de levage et de manutention de l'état de la technique, notamment divulgué par le document FR 2 946 376 , afin de pouvoir poser des plaques ou panneaux dans les trois positions, horizontale, sous-rampant et verticale, tout en incluant un système d'articulation et de présentation des plaques ou panneaux qui soit simple de conception, de fabrication et d'utilisation.The applicant's approach was to find out how to modify the lifting and handling equipment of the state of the art, in particular disclosed by the document FR 2 946 376 , in order to be able to lay plates or panels in three positions, horizontal, sub-crawling and vertical, while including a system of articulation and presentation of the plates or panels that is simple to design, manufacture and use.

Le demandeur s'est aussi intéressé à l'optimisation et fabrication de l'appareil de levage et manutention en recherchant d'autres fonctions répondant à un besoin dans le cadre de la manipulation des appareils sur site.The applicant has also been interested in the optimization and manufacture of the lifting and handling equipment by searching for other functions that meet a need in the field handling of equipment.

Un autre objectif de l'invention est de faciliter les interventions et manipulations de l'opérateur, avec un appareil offrant le plus de facilités d'utilisation.Another object of the invention is to facilitate the interventions and manipulations of the operator, with a device offering the most ease of use.

A cet effet, il a été mis au point un dispositif porte plaque pour appareil de levage et de manutention du type comprenant un mât et permettant la pose d'une plaque en tous matériaux pour constituer des faux plafonds, ou pour un aménagement sous rampant et sur cloisons.To this end, it has been developed a plate holder device for lifting and handling of the type comprising a mast and allowing the installation of a plate of any material to form false ceilings, or for a development under crawling and on partitions.

Selon l'invention, le dispositif porte plaque comprend un système d'articulation destiné à venir se fixer sur le mât de l'appareil, et une ossature support définissant un plan de réception d'une plaque. L'ossature support est montée sur le système d'articulation avec capacité de rotation autour d'un axe orthogonal au plan de réception, et le système d'articulation est articulé autour d'un axe parallèle au plan de réception et comprend une poignée assujettie à des moyens de verrouillage permettant à un utilisateur de faire basculer l'ossature support dans des positions horizontale, inclinée et verticale, et de verrouiller au moins les positions horizontale et inclinée directement à partir de la poignée.According to the invention, the plate holder device comprises a hinge system intended to be fixed on the mast of the apparatus, and a support frame defining a plane for receiving a plate. The support frame is mounted on the hinge system with rotational capacity about an axis orthogonal to the receiving plane, and the hinge system is hinged about an axis parallel to the receiving plane and comprises a grip attached locking means enabling a user to tilt the support frame in horizontal, inclined and vertical positions, and to lock at least the horizontal and inclined positions directly from the handle.

De cette manière, l'invention permet la pose de plaques ou panneaux à l'horizontale, de manière inclinée dite « sous rampant », et à la verticale, sans nécessiter un quelconque démontage d'un élément pour passer d'une position à une autre, mais par un simple pivotement de l'ossature support autour d'un axe situé sur le système d'articulation. De plus, les interventions et manipulations de l'opérateur sont facilitées car il peut poser les plaques selon trois positions, et passer d'une position verrouillée à une autre en manipulant l'appareil avec une seule main, notamment celle qui tient la poignée.In this way, the invention allows the laying of plates or panels horizontally, inclined so-called "sub-rampant", and vertically, without requiring any disassembly of an element to move from a position to a other, but by a simple pivoting of the support frame around an axis located on the articulation system. Of more, interventions and manipulations of the operator are facilitated because it can put the plates in three positions, and move from one locked position to another by manipulating the device with one hand, including the one holding the handle.

Selon une forme de réalisation particulière, le système d'articulation comprend un profilé support destiné à se fixer transversalement à une extrémité libre du mât de l'appareil, et un socle en forme de « U » renversé définissant deux ailes et une base. Le socle est monté sur le profilé support de manière pivotante autour d'un axe traversant transversalement les deux ailes et le profilé support. De cette manière, le système d'articulation est simple de conception, de fabrication et d'utilisationAccording to a particular embodiment, the articulation system comprises a support profile intended to be fixed transversely to a free end of the mast of the apparatus, and an inverted "U" shaped base defining two wings and a base. The base is mounted on the support profile pivotally about an axis traversing transversely the two wings and the support profile. In this way, the articulation system is simple to design, manufacture and use

Selon un exemple de réalisation, les moyens de verrouillage du système d'articulation comprennent un secteur fixé sur le profilé support. Le secteur comprend au moins deux crans décalés angulairement dans lesquels un verrou est apte à s'engager pour verrouiller le système d'articulation selon au moins les positions horizontale ou inclinée de l'ossature support. Le verrou est monté mobile à l'encontre d'un ressort qui pousse ledit verrou contre le secteur pour l'engager dans les crans. Le verrou est relié à une tige actionnable par un levier de manoeuvre disposé au niveau de la poignée pour permettre à l'utilisateur de désengager le verrou et de varier la position de l'ossature support.According to an exemplary embodiment, the locking means of the articulation system comprise a sector fixed on the support profile. The sector comprises at least two notches angularly offset in which a lock is adapted to engage to lock the hinge system in at least the horizontal or inclined position of the support frame. The latch is movably mounted against a spring which pushes said latch against the sector to engage it in the notches. The lock is connected to a rod operable by an operating lever disposed at the handle to allow the user to disengage the lock and vary the position of the support frame.

De préférence, le verrou comporte une portion d'extrémité biseautée au niveau d'une partie inférieure, de manière à ce que, lors du passage de la position inclinée à la position horizontale de l'ossature support, le verrou se désengage automatiquement des crans, sans intervention de l'utilisateur sur les moyens de verrouillage.Preferably, the lock comprises a tapered end portion at a lower portion, so that, during the passage from the inclined position to the horizontal position of the support frame, the lock automatically disengages the notches without user intervention on the locking means.

Selon un exemple particulier de réalisation, une première platine est solidaire de la base du socle du système d'articulation, et une deuxième platine est solidaire de l'ossature support. La deuxième platine est montée sur la première platine, face contre face, et la première platine et la deuxième platine comprenant chacune au moins une lumière profilée selon un arc de cercle. Une tige traverse les lumières profilées pour permettre la rotation de la deuxième platine sur la première platine et autour d'un axe orthogonal aux platines.According to a particular embodiment, a first plate is secured to the base of the base of the articulation system, and a second plate is secured to the support frame. The second plate is mounted on the first plate, face to face, and the first plate and the second plate each comprising at least one profiled light according to a circular arc. A rod passes through the profiled lights to allow the rotation of the second plate on the first plate and around an axis orthogonal to the plates.

Avantageusement, la première platine et la deuxième platine comprennent des moyens de verrouillage de la rotation de la deuxième platine selon diverses positions. Par exemple, les moyens de verrouillage comprennent un orifice ménagé au travers de la première platine, et deux orifices d'indexation décalés de 90° ménagés au travers de la deuxième platine et aptes à venir en correspondance avec l'orifice de la première platine lors de la rotation de la deuxième platine., Une goupille est insérée dans le premier orifice et est montée mobile à l'encontre d'un ressort de compression qui pousse ladite goupille contre la deuxième platine pour pénétrer dans l'un des orifices et verrouiller la position.Advantageously, the first plate and the second plate comprise means for locking the rotation of the second plate in various positions. For example, the locking means comprise an orifice formed through the first plate, and two indexing holes offset by 90 ° formed through the second plate and able to come into correspondence with the orifice of the first plate during of the rotation of the second platen. A pin is inserted into the first port and is movably mounted against a compression spring which urges said pin against the second platen to penetrate one of the ports and lock the gate. position.

De cette manière, la conception et simple. L'utilisateur tire sur la goupille pour déverrouiller les platines et pivoter l'ossature support de 90°. Le verrouillage en position de l'ossature support est automatique lorsqu'une position, par exemple horizontale ou verticale, est atteinte.In this way, the design and simple. The user pulls on the pin to unlock the plates and rotate the support frame 90 °. The locking in position of the support frame is automatic when a position, for example horizontal or vertical, is reached.

L'invention vise à protéger également un appareil de levage et de manutention comprenant un mât et permettant la pose d'une plaque en tous matériaux pour constituer des faux plafonds, ou pour un aménagement sous rampant et sur cloisons, et comprenant un dispositif porte plaque conforme à l'une quelconque des caractéristiques précitées, fixé à une extrémité libre du mât.The invention also aims to protect a lifting and handling device comprising a mast and allowing the installation of a plate of any material to form false ceilings, or for a crawling and partitions arrangement, and comprising a plate holder device. according to any one of the aforementioned characteristics, fixed to a free end of the mast.

DESCRIPTION DÉTAILLÉE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence à la figure 1, l'invention concerne un appareil (1) de levage et de manutention permettant la pose d'une plaque ou panneau en tous matériaux pour constituer des faux plafonds, ou pour un aménagement sous rampant et sur cloisons.With reference to the figure 1 The invention relates to an apparatus (1) for lifting and handling for the installation of a plate or panel of any material to form false ceilings, or for a development under crawling and partitions.

L'invention concerne plus particulièrement un dispositif porte plaque (2) que comprend l'appareil (1) de levage, fixé à une extrémité libre d'un mât (3) que comprend l'appareil (1).The invention more particularly relates to a plate holder device (2) that comprises the lifting device (1), attached to a free end of a mast (3) that includes the apparatus (1).

En référence aux figures 1 à 3, 7, 9, 11 et 12, le dispositif porte plaque (2) comprend un système d'articulation (4) destiné à venir se fixer sur le mât (3) de l'appareil (1), par tous moyens appropriés bien connus de l'état de la technique, et une ossature support (5) montée sur le système d'articulation (4) et définissant un plan de réception d'une plaque. L'ossature support (5) est également bien connue de l'état de la technique et ne sera pas décrite plus en détail.With reference to Figures 1 to 3 , 7 , 9 , 11 and 12 , the plate holder device (2) comprises a hinge system (4) intended to be fixed on the mast (3) of the apparatus (1), by any appropriate means well known in the state of the art, and a support frame (5) mounted on the articulation system (4) and defining a plane for receiving a plate. The support frame (5) is also well known in the state of the art and will not be described in more detail.

Selon une première caractéristique, le système d'articulation (4) comprend un profilé support (6) fixé transversalement, par tous moyens appropriés et bien connus, à une extrémité libre du mât (3) de l'appareil (1).According to a first feature, the articulation system (4) comprises a support profile (6) fixed transversely, by any appropriate and well known means, at a free end of the mast (3) of the apparatus (1).

Le système d'articulation (4) est articulé autour d'un axe (7) parallèle au plan de réception de la plaque et comprend une poignée (8) assujettie à des moyens de verrouillage (9) permettant à un utilisateur de faire basculer l'ossature support (5) dans des positions horizontale, inclinée et verticale, et de verrouiller au moins les positions horizontale et inclinée directement à partir de la poignée (8).The articulation system (4) is articulated about an axis (7) parallel to the plane of reception of the plate and comprises a handle (8) secured to locking means (9) allowing a user to tilt the support frame (5) in horizontal, inclined and vertical positions, and to lock at least the horizontal and inclined positions directly from the handle (8).

A cet effet, et en référence à la figure 2, le système d'articulation (4) comprend un socle support (10) en forme de « U » renversé, définissant deux ailes (11) et une base (12). Le socle (10) est monté sur le profilé support (6) d'une manière pivotante par rapport à ce dernier autour de l'axe (7) qui traverse transversalement les deux ailes (11) et le profilé support (6). Le socle (10) est assujetti à la poignée (8) pour faire basculer le système d'articulation (4), et donc l'ossature support (5) dans les trois positions différentes possibles.For this purpose, and with reference to figure 2 the hinge system (4) comprises an u-shaped support pedestal (10), which defines two wings (11) and a base (12). The base (10) is mounted on the support profile (6) pivotally relative thereto around the axis (7) which transversely traverses the two wings (11) and the support profile (6). The base (10) is secured to the handle (8) to tilt the hinge system (4), and thus the support frame (5) in three different possible positions.

En référence aux figures 2 et 7, l'ossature support (5) comprend une platine (13), par exemple de forme générale circulaire, montée, face contre face, sur une platine (14) correspondante solidaire de la base (12) du socle (10) du système d'articulation (4), et avec capacité de rotation autour d'un axe orthogonal au plan de réception et aux platines (13, 14). Les deux platines (13, 14) comprenant chacune au moins une lumière profilée (15) selon un arc de cercle, et sont toutes les deux traversées par une même tige (16) pour permettre la rotation de la platine (13) de l'ossature support (5) sur la platine (14) du socle (10) et autour d'un axe orthogonal aux platines (13, 14).With reference to figures 2 and 7 , the support frame (5) comprises a plate (13), for example of generally circular shape, mounted face-to-face on a corresponding plate (14) integral with the base (12) of the base (10) of the mounting system. articulation (4), and with rotational capacity about an axis orthogonal to the receiving plane and the plates (13, 14). The two plates (13, 14) each comprising at least one profile light (15) in a circular arc, and both are traversed by the same rod (16) to allow the rotation of the plate (13) of the support frame (5) on the plate (14) of the base (10) and around an axis orthogonal to the plates (13, 14).

Avantageusement, la platine (13) de l'ossature support (5) comprend un cylindre centreur en saillie coopérant avec une ouverture centrale complémentaire sur la platine (14) du socle (10) pour guider de manière optimale la rotation de la platine (13) de l'ossature support (5).Advantageously, the plate (13) of the support frame (5) comprises a projecting central cylinder cooperating with a complementary central opening on the plate. (14) of the base (10) to optimally guide the rotation of the plate (13) of the support frame (5).

L'ossature support (5) est donc orientable selon une amplitude de 90° permettant le chargement d'une plaque en position horizontale (Fig. 1) ou verticale (Fig. 11). En référence à la figure 7, les platines (13, 14) comprennent des moyens de verrouillage (17) de la rotation de la platine (13) de l'ossature support (5) selon ces diverses positions. A cet effet, et en référence à la figure 10, un orifice est ménagé au travers de la platine (14) du socle (10), et deux orifices (19) d'indexation, décalés de 90°, sont ménagés au travers de la platine (13) de l'ossature support (5). Ces deux derniers orifices (19) sont aptes, lors de la rotation de la platine (13), à venir en correspondance avec l'orifice de la platine (14). En référence aux figures 7 et 8, les moyens de verrouillage (17) comprennent également une goupille (20), insérée dans l'orifice de la platine (14), et montée mobile à l'encontre d'un ressort de compression (21) qui pousse ladite goupille (20) contre la platine (13) pour pénétrer dans l'un des orifices (19) et verrouiller la position. Ainsi, la goupille (20) permet l'immobilisation de l'ossature support (5) dans l'une des deux positions horizontale ou verticale. De préférence, la goupille (20) comprend un anneau brisé (22) à son extrémité libre afin de faciliter sa préhension par un utilisateur et son désengagement des orifices (19) pour déverrouiller la position de l'ossature support (5).The support frame (5) is therefore orientable at an amplitude of 90 ° allowing the loading of a plate in a horizontal position ( Fig. 1 ) or vertical ( Fig. 11 ). With reference to the figure 7 , the plates (13, 14) comprise locking means (17) for the rotation of the plate (13) of the support frame (5) in these various positions. For this purpose, and with reference to figure 10 , an orifice is formed through the plate (14) of the base (10), and two indexing orifices (19), offset by 90 °, are formed through the plate (13) of the support frame ( 5). These last two orifices (19) are suitable, during the rotation of the plate (13), to come in correspondence with the orifice of the plate (14). With reference to Figures 7 and 8 , the locking means (17) also comprise a pin (20), inserted in the orifice of the plate (14), and mounted movably against a compression spring (21) which pushes said pin (20). ) against the plate (13) to enter one of the orifices (19) and lock the position. Thus, the pin (20) allows the immobilization of the support frame (5) in one of the two horizontal or vertical positions. Preferably, the pin (20) comprises a broken ring (22) at its free end to facilitate its grip by a user and its disengagement of the orifices (19) to unlock the position of the support frame (5).

Comme indiqué plus haut, des moyens de verrouillage (9) permettent à l'utilisateur de faire basculer l'ossature support (5) dans des positions horizontale, inclinée et verticale, et de verrouiller au moins les positions horizontale et inclinée directement à partir de la poignée (8), avec une seule main et sans aucun démontage.As indicated above, locking means (9) allow the user to tilt the support frame (5) in horizontal, inclined and vertical positions, and to lock at least the horizontal and inclined positions directly from the handle (8), with one hand and without any disassembly.

A cet effet, en référence aux figures 2, 3, 5, 9 et 12, les moyens de verrouillage (9) comprennent une pièce formant un secteur (23) et ayant un profil en quart de cercle. Le secteur (23) est solidaire du profilé support (6), et est notamment monté autour de l'axe (7). Le secteur (23) comprend au moins deux crans (24) décalés angulairement, dont un premier cran aligné avec l'horizontale et un deuxième cran décalé de 45°. Les moyens de verrouillage (9) comprennent également un verrou (25) monté mobile dans une chape (26) fixée au socle (10), et à l'encontre d'un ressort (27) disposé à l'intérieur de la chape (26) pour pousser ledit verrou (25) contre le secteur (23) et l'engager dans l'un des crans (24) afin de verrouiller le système d'articulation (4) selon au moins l'une des positions horizontale ou inclinée de l'ossature support (5).For this purpose, with reference to Figures 2, 3, 5 , 9 and 12 , the locking means (9) comprise a part forming a sector (23) and having a quarter-circle profile. The sector (23) is integral with the support profile (6), and is in particular mounted around the axis (7). The sector (23) comprises at least two notches (24) angularly offset, a first notch aligned with the horizontal and a second notch offset by 45 °. The locking means (9) also comprise a latch (25) movably mounted in a yoke (26) fixed to the base (10), and against a spring (27) disposed inside the yoke ( 26) to push said latch (25) against the sector (23) and engage it in one of the notches (24) for locking the hinge system (4) in at least one of the horizontal or inclined positions of the support frame (5).

En référence à la figure 4, le verrou (25) se présente sous la forme d'une pièce allongée rectangulaire, avec une portion d'extrémité (28) biseautée, à la manière d'un pêne d'une serrure, pour se verrouiller dans les crans (24) et empêcher le basculement de l'ossature support (5) selon une direction vers le haut, c'est-à-dire lors du passage de la position horizontale à la position vertical du système d'articulation (4). Le basculement selon une direction vers le bas est possible par une traction sur la poignée (8) et permet, du fait de la portion biseautée (28), le désengagement du verrou (25).With reference to the figure 4 the latch (25) is in the form of a rectangular elongated piece, with a beveled end portion (28), in the manner of a latch of a lock, for locking in the notches (24) and preventing tilting of the support frame (5) in an upward direction, i.e. when moving from the horizontal position to the vertical position of the hinge system (4). Tipping in a downward direction is possible by pulling on the handle (8) and allows, due to the tapered portion (28), the disengagement of the lock (25).

Le verrou (25) comprend, au niveau d'une portion d'extrémité opposée à la portion biseautée, une encoche (29) dans laquelle une extrémité repliée d'une tige (30) peut s'engager. L'autre extrémité de la tige (30) est reliée à un levier de manoeuvre (31) disposé au niveau de la poignée (8) et permettant à l'utilisateur d'actionner la tige (30) pour désengager le verrou (25) des crans (24) et varier la position de l'ossature support (5).The latch (25) includes, at an end portion opposite the tapered portion, a notch (29) in which a folded end of a rod (30) is engageable. The other end of the rod (30) is connected to an operating lever (31) disposed at the handle (8) and allowing the user to actuate the rod (30) to disengage the latch (25) notches (24) and varying the position of the support frame (5).

La position à la verticale de l'ossature support (5) ne correspond pas à une position verrouillée. Bien entendu, l'Homme du Métier peut tout à fait envisager de ménager un cran dans le secteur (23) pour le verrouillage de cette position verticale, mais en pratique, cela ne semble pas nécessaire.The vertical position of the support frame (5) does not correspond to a locked position. Of course, those skilled in the art can quite consider providing a notch in the sector (23) for locking this vertical position, but in practice, this does not seem necessary.

En pose horizontale, il est possible de ne pas immobiliser la rotation de l'ossature support (5) autour de l'axe orthogonal au plan de réception pour permettre à l'utilisateur d'ajuster le positionnement de la plaque.In horizontal laying, it is possible not to immobilize the rotation of the support frame (5) around the axis orthogonal to the receiving plane to allow the user to adjust the positioning of the plate.

Pour procéder à la pose d'une plaque sous un plan incliné appelé « sous rampant », l'utilisateur part de la position inclinée. L'utilisateur présente ensuite la plaque sous le plan incliné, et au moment où le sommet de la plaque vient en contact avec le plan incliné, l'utilisateur continue d'élever la plaque, pour permettre au verrou (25) de se désengager automatiquement du cran (24), et permettre à la plaque de se positionner automatiquement selon l'angle du rampant. L'utilisateur procède ensuite à la fixation de la plaque sur le support plan incliné.To proceed with the laying of a plate under an inclined plane called "under crawling", the user starts from the inclined position. The user then presents the plate under the inclined plane, and when the top of the plate comes into contact with the inclined plane, the user continues to raise the plate, to allow the lock (25) to disengage automatically from the notch (24), and allow the plate to position itself automatically according to the angle of the rampant. The user then proceeds to fix the plate on the inclined support plane.

L'avantage du dispositif selon l'invention est que celui-ci passe de la position verticale à la position inclinée, ou de la position inclinée à la position horizontale par simple action sur la poignée (8), le verrou (25) se désengage de manière automatique. L'utilisateur n'a donc qu'une seule main occupée et son autre main lui permet de maintenir en position l'appareil (1) ou de diriger celui-ci.The advantage of the device according to the invention is that it passes from the vertical position to the inclined position, or from the inclined position to the horizontal position by simple action on the handle (8), the latch (25) disengages automatically. The user therefore has only one hand occupied and his other hand allows him to hold the device (1) in position or to direct it.
