Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne un support de plaque pour un appareil destiné à la pose de plaques en tous matériaux, telles que des plaques de plâtre par exemple, pour constituer des faux plafonds ou l'aménagement sous rampants et sur cloisons.The present invention relates to a plate support for an apparatus for laying plates made of any material, such as gypsum boards for example, to constitute false ceilings or crawling and partitions.

ARRIERE-PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Afin de faciliter la pose de plaques de plafond ou l'aménagement de rampants, il est bien connu d'utiliser des appareils manuels dits « lève-plaque » qui comprennent, en référence à la figure 1, un pied support (1) constitué de trois pieds (1a,1b,1c) repliables et dont les extrémités sont avantageusement munies de roulettes (2), un mât central (3) télescopique en deux ou plusieurs éléments, dont l'allongement est obtenu au moyen d'un treuil manuel (4) actionné par un volant (5) et d'au moins un câble (6) actionné par ledit treuil (4), et d'un support de plaque (7) monté à l'extrémité supérieure de l'élément supérieur du mât central (3), ledit support de plaque (7) étant avantageusement inclinable par rapport à l'horizontal.In order to facilitate the installation of ceiling plates or crawling installation, it is well known to use manual apparatus called "plate lifters" which include, with reference to the figure 1 , a support leg (1) consisting of three legs (1a, 1b, 1c) foldable and whose ends are advantageously provided with wheels (2), a central mast (3) telescopic in two or more elements, whose elongation is obtained by means of a manual winch (4) actuated by a flywheel (5) and at least one cable (6) actuated by said winch (4), and a plate support (7) mounted to the upper end of the upper element of the central mast (3), said plate support (7) being advantageously inclinable relative to the horizontal.

Ledit support de plaque (6) est usuellement constitué d'une barre centrale horizontale (8) et de deux bras transversaux (9) s'étendant transversalement aux extrémités de ladite barre centrale (8) de sorte que le support de plaque (7) présente une forme générale de H. Chaque bras transversal (9) comporte à l'une de ses extrémités libre un crochet (10) sur lequel est apte à prendre appui le bord d'une plaque. Lesdits crochets (10) sont avantageusement montés libres en rotation afin de permettre leur retrait lorsque la plaque est plaquée contre le plafond par exemple.Said plate support (6) is usually constituted by a horizontal central bar (8) and two transverse arms (9) extending transversely to the ends of said central bar (8) so that the plate support (7) has a general shape H. Each transverse arm (9) has at one of its free ends a hook (10) on which is able to bear the edge of a plate. Said hooks (10) are advantageously rotatably mounted to allow their removal when the plate is pressed against the ceiling, for example.

Par ailleurs, le support de plaque (7) comporte deux bras longitudinaux (11) en forme de T, chaque bras longitudinal (11) comportant une branche médiane (12) montée coulissante à l'une des extrémités de la barre centrale (8) et une partie tubulaire (13) s'étendant transversalement à la branche médiane (12), ladite partie tubulaire (13) étant avantageusement munie de patins en caoutchouc (14) ou similaire afin d'éviter que la plaque ne glisse lorsqu'elle est positionnée sur le support de plaque (7).Furthermore, the plate support (7) comprises two T-shaped longitudinal arms (11), each longitudinal arm (11) comprising a central branch (12) slidably mounted at one end of the central bar (8). and a tubular portion (13) extending transversely to the medial limb (12), said tubular portion (13) being advantageously provided with rubber pads (14) or the like to prevent the plate from slipping when it is positioned on the plate support (7).

Ce type d'appareil « lève-plaque », ainsi que les « lève-plaques » décrits dans les demandes de brevet européen EP 0777021 et EP 0856621 , permet d'élever les plaques de plafond à la hauteur désirée et de maintenir ces plaques en hauteur afin de faciliter leur pose. Le montage pivotant du support de plaque à l'extrémité supérieure du mât facilite la mise en place initiale de chaque plaque de plafond sur l'appareil et le placement de chaque plaque levée, soit en position horizontale, pour la réalisation d'un plafond ordinaire, soit en position inclinée, pour une pose dite « sous rampant ».This type of "plate lifter" device, as well as the "lifts" described in the European patent applications EP 0777021 and EP 0856621 , allows to raise the ceiling plates to the desired height and to maintain these plates in height to facilitate their installation. The pivotal mounting of the plate support at the upper end of the mast facilitates the initial placement of each ceiling plate on the apparatus and the placement of each raised plate, in a horizontal position, for the realization of a standard ceiling. , or in an inclined position, for a so-called "under crawling" installation.

Les supports de plaque de ces appareils « lève plaque » ne sont pas adaptés pour la pose de plaques verticales, pour la réalisation de cloisons ou de murs.The plate supports of these "plate lifters" are not suitable for laying vertical plates, for the realization of partitions or walls.

Par ailleurs, les appareils « lève-plaque » de l'art antérieur sont généralement démontables afin de réduire leur encombrement lorsqu'ils ne sont pas utilisés. Ainsi, le mât peut être désolidarisé du pied support qui est généralement repliable et le support de plaque peut être désolidarisé de l'extrémité supérieure du mât.In addition, the "lifter plate" devices of the prior art are generally removable to reduce their size when not in use. Thus, the mast can be detached from the support leg which is generally collapsible and the plate support can be detached from the upper end of the mast.

Toutefois, les supports de plaque de l'art antérieur présentent l'inconvénient d'être encombrants y compris après démontage.However, the plate supports of the prior art have the disadvantage of being bulky even after disassembly.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'un des buts de l'invention est donc de remédier à ces inconvénients en proposant un support de plaques de conception simple et peu onéreuse, apte à être solidarisé à tout type d'appareil « lève plaque », présentant un faible encombrement après utilisation et permettant la pose de plaques aussi bien horizontales, pour la réalisation de plafonds, qu' inclinées pour une pose dite « sous rampant » ou verticale pour la réalisation de cloisons ou de murs.One of the aims of the invention is therefore to remedy these drawbacks by proposing a plate support of simple and inexpensive design, adapted to be secured to any type of device "lifts plate", having a small footprint after use and allowing the laying of plates both horizontal, for the realization of ceilings, that inclined for a so-called "sub-crawling" or vertical installation for the realization of partitions or walls.

A cet effet, et conformément à l'invention, il est proposé un support de plaque (7) destiné à être monté à l'extrémité supérieure de l'élément supérieur du mât central d'un appareil « lève-plaque » ou similaire ; ledit support de plaque est remarquable en ce qu'il comporte au moins un corps central longitudinal constitué de deux plaques sensiblement rectangulaires séparées par trois parois longitudinales formant au moins deux fourreaux centraux, chaque fourreau central recevant un bras transversal en forme général de T qui comprend une branche médiane longitudinale montée coulissante dans un fourreau et une partie tubulaire transversale soudée à l'extrémité libre de la branche médiane, ladite partie tubulaire transversale s'étendant sensiblement dans le plan du corps central.For this purpose, and in accordance with the invention, there is provided a plate support (7) to be mounted at the upper end of the upper member of the central mast of a "lifter" apparatus or the like; said plate support is remarkable in that it comprises at least one longitudinal central body consisting of two substantially rectangular plates separated by three longitudinal walls forming at least two central sleeves, each central sleeve receiving a generally T-shaped transverse arm which comprises a longitudinal middle branch slidably mounted in a sheath and a transverse tubular portion welded to the free end of the middle branch, said transverse tubular portion extending substantially in the plane of the central body.

On comprend bien que, contrairement aux supports de plaque de l'art antérieur, le support de plaque suivant l'invention permet de replier l'ensemble des éléments dans les fourreaux centraux et les gorges périphériques afin de réduire son encombrement.It is well understood that, unlike the plate supports of the prior art, the plate support according to the invention makes it possible to fold all the elements in the central sleeves and the peripheral grooves to reduce its bulk.

De préférence, chaque branche médiane comporte un doigt coopérant avec un ressort et apte à être introduit dans des lumières pratiquées le long de la branche médiane afin de régler la longueur de la branche médiane longitudinale des bras transversaux faisant saillie des fourreaux en fonction des dimensions de la plaque à porter.Preferably, each median branch comprises a finger cooperating with a spring and able to be introduced into the lights along the middle branch in order to adjust the length of the longitudinal median branch of the transverse arms projecting from the sleeves according to the dimensions of the plate to wear.

Afin de permettre la pose de plaques verticales, au moins l'une des parties tubulaires transversales des bras transversaux comporte des butées d'arrêt s'étendant orthogonalement par rapport auxdites parties tubulaires transversales et aux branches médianes.In order to allow the installation of vertical plates, at least one of the transverse tubular portions of the transverse arms comprises stop stops extending orthogonally with respect to said transverse tubular portions and the median branches.

De préférence, ces butées d'arrêt sont positionnées symétriquement de part et d'autre de la branche médiane longitudinale, à proximité des extrémités libres de la partie tubulaire transversale.Preferably, these stoppers are positioned symmetrically on either side of the longitudinal central branch, near the free ends of the transverse tubular portion.

De plus, de préférence, le corps central longitudinal est constitué de deux plaques sensiblement rectangulaires séparées par trois parois longitudinales formant deux fourreaux centraux et deux gorges périphériques.In addition, preferably, the longitudinal central body consists of two substantially rectangular plates separated by three longitudinal walls forming two central sleeves and two peripheral grooves.

De manière avantageuse, le support de plaque suivant l'invention comporte deux bras transversaux respectivement articulés autour d'un axe solidaire des extrémités libres du corps central au niveau de la gorge périphérique et deux bras transversaux respectivement articulés autour d'un axe solidaire des extrémités libres du corps central au niveau de la gorge périphérique opposée.Advantageously, the plate support according to the invention comprises two transverse arms respectively hinged about an axis integral with the free ends of the central body at the peripheral groove and two transverse arms respectively articulated about an axis integral with the ends. free of the central body at the opposite peripheral groove.

Par ailleurs, les plaques font saillies des gorges périphériques, au niveau des extrémités libres du corps central, pour former des joues dans lesquelles sont pratiquées des lumières curvilignes qui constituent des chemins de came dans lesquelles sont aptes à se déplacer des ergots, formant une came, solidaires des bras de sorte que ces derniers soient aptes à se déplacer depuis une position repliée où les bras s'étendent dans les gorges périphériques et respectivement jusqu'à une position dépliée où lesdits bras s'étendent orthogonalement au corps central.Furthermore, the plates protrude from the peripheral grooves, at the free ends of the central body, to form cheeks in which are formed curvilinear lights which constitute cam paths in which are able to move lugs, forming a cam , integral with the arms so that the latter are able to move from a folded position where the arms extend in the peripheral grooves and respectively to an unfolded position where said arms extend orthogonally to the central body.

Selon une variante d'exécution du support de plaque suivant l'invention, ledit support de plaque comporte deux bras cintrés s'étendant le long du corps central, sous ce dernier, de part et d'autre de l'axe longitudinal dudit corps central. Ces bras cintrés forment des moyens de préhension permettant le transport aisé dudit support tout en procurant une bonne répartition des masses.According to an alternative embodiment of the plate support according to the invention, said plate support comprises two bent arms extending along the central body, under the latter, on either side of the longitudinal axis of said central body. . These bent arms form gripping means for easy transport of said support while providing a good distribution of masses.

De manière avantageuse, lesdits bras cintrés sont reliés dans leur partie centrale par une entretoise portant un volant s'étendant entre l'entretoise et le corps central.Advantageously, said bent arms are connected in their central part by a spacer carrying a wheel extending between the spacer and the central body.

Les fourreaux centraux (14) reçoivent respectivement un bras transversal (17) en forme général de T comprenant une branche médiane longitudinale (18) montée coulissante dans un fourreau (14) et une partie tubulaire transversale (19) soudée à l'extrémité libre de la branche médiane (18), ladite partie tubulaire transversale (19) s'étendant sensiblement dans le plan du corps central (11).The central sleeves (14) respectively receive a generally T-shaped transverse arm (17) comprising a longitudinal central branch (18) slidably mounted in a sleeve (14) and a transverse tubular portion (19) welded to the free end of the middle branch (18), said transverse tubular portion (19) extending substantially in the plane of the central body (11).

Afin de régler la longueur de la branche médiane longitudinale (18) des bras transversaux faisant saillie des fourreaux (14), en fonction des dimensions de la plaque à porter, chaque branche médiane (18) comporte un doigt (20) coopérant avec un ressort et apte à être introduit dans des lumières (21) pratiquées le long de la branche médiane (18).In order to adjust the length of the longitudinal middle branch (18) of the transverse arms projecting from the sleeves (14), depending on the dimensions of the plate to be carried, each middle branch (18) comprises a finger (20) cooperating with a spring and adapted to be introduced into lights (21) made along the middle branch (18).

En référence, aux figures 2, 3, 4 et 5, au moins l'une des parties tubulaires transversales (19) des bras transversaux comporte des butées d'arrêt (22) s'étendant orthogonalement par rapport auxdites parties tubulaires transversales (19) et aux branches médianes (18). Ces butées d'arrêt (22) sont positionnées symétriquement de part et d'autre de la branche médiane longitudinale (18), à proximité des extrémités libres de la partie tubulaire transversale (19) et sont destinées à recevoir le bord d'une plaque à poser verticalement, le support de plaque (7) étant alors orienté verticalement sur l'appareil « lève-plaque » non représenté sur les figures.With reference to Figures 2, 3 , 4 and 5 at least one of the transverse tubular portions (19) of the transverse arms has stops (22) extending orthogonally with respect to said transverse tubular portions (19) and the medial branches (18). These stops (22) are positioned symmetrically on either side of the longitudinal central branch (18), near the free ends of the transverse tubular portion (19) and are intended to receive the edge of a plate to pose vertically, the plate support (7) then being oriented vertically on the device "lifter plate" not shown in the figures.

Par ailleurs, en référence aux figures 2 et 3, le support de plaque (7) suivant l'invention comporte des bras transversaux articulés, deux bras (23) respectivement articulés autour d'un axe (24) solidaire des extrémités libres du corps central (11) au niveau de la gorge périphérique (16) et deux bras (25) respectivement articulés autour d'un axe (26) solidaire des extrémités libres du corps central (11) au niveau de la gorge périphérique opposée (15).Moreover, with reference to Figures 2 and 3 , the plate support (7) according to the invention comprises articulated transverse arms, two arms (23) articulated respectively about an axis (24) integral with the free ends of the central body (11) at the peripheral groove ( 16) and two arms (25) hinged respectively about an axis (26) integral with the free ends of the central body (11) at the opposite peripheral groove (15).

Les plaques (12) font saillies des gorges périphériques (15) et (16), au niveau des extrémités libres du corps central (11), pour former des joues (27) dans lesquelles sont pratiquées des lumières curvilignes (28). Ces lumières curvilignes (28) constituent des chemins de came dans lesquelles sont aptes à se déplacer des ergots (29), formant une came, solidaires des bras (23) et (25) de sorte que ces derniers sont aptes à se déplacer depuis une position repliée (figures 4 et 5) où les bras (23) et (25) s'étendent dans les gorges périphériques (15) et respectivement (16) jusqu'à une position dépliée où lesdits bras (23) et (25) s'étendent orthogonalement au corps central (11).The plates (12) protrude from the peripheral grooves (15) and (16) at the free ends of the central body (11) to form cheeks (27) in which curvilinear lumens (28) are formed. These curvilinear lights (28) constitute cam paths in which cams (29) which are integral with the arms (23) and (25) are movable so that the latter are able to move for a period of time. folded position ( Figures 4 and 5 ) where the arms (23) and (25) extend in the peripheral grooves (15) and respectively (16) to an unfolded position where said arms (23) and (25) extend orthogonally to the central body (11).

Une première paire de bras (25) présente une longueur inférieure à la moitié de la longueur du corps central (11). L'autre paire de bras (23) présente une longueur sensiblement égale à la moitié de la longueur dudit corps central (11) et, chaque bras (23) comporte à son extrémité libre une butée d'arrêt (30) s'étendant orthogonalement aux bras (23) et aux plaques (12) formant le corps central (11).A first pair of arms (25) has a length less than half the length of the central body (11). The other pair of arms (23) has a length substantially equal to half the length of said central body (11) and each arm (23) has at its free end a stop (30) extending orthogonally the arms (23) and the plates (12) forming the central body (11).

Afin de permettre le repliage des bras (23) dans la gorge périphérique (15), les bords des plaques (12) comportent dans leur partie médiane une découpe (31) sensiblement rectangulaire, et correspondant sensiblement à la profondeur de la gorge périphérique (15), ladite découpe (31) permettant le passage des butées d'arrêt (30) qui font saillie des extrémités libres des bras (23) lorsque ces derniers sont repliés dans ladite gorge périphérique (15).In order to allow the folding of the arms (23) in the peripheral groove (15), the edges of the plates (12) comprise in their central part a substantially rectangular cut-out (31) corresponding substantially to the depth of the peripheral groove (15). ), said cutout (31) for the passage of the stops (30) which project from the free ends of the arms (23) when the latter are folded in said peripheral groove (15).

On notera que ces butées d'arrêt (30) sont destinées à recevoir le bord d'une plaque à poser horizontalement ou de manière inclinée, le support de plaque (7) étant alors orienté horizontalement ou de manière inclinée sur l'appareil « lève-plaque » non représenté sur les figures.Note that these stops (30) are intended to receive the edge of a plate to be laid horizontally or in an inclined manner, the plate support (7) then being oriented horizontally or in an inclined manner on the device "lifts -plaque "not shown in the figures.

Par ailleurs, on observera que, lorsque les bras (23) et (25) sont repliés dans les gorges périphériques (15) et respectivement (16) et les bras transversaux repliés dans leurs fourreaux (14), le support de plaque (7) suivant l'invention présente un encombrement minimal facilitant sont rangement et/ou son transport.Furthermore, it will be observed that when the arms (23) and (25) are folded in the peripheral grooves (15) and respectively (16) and the transverse arms folded in their sleeves (14), the plate support (7) according to the invention has a minimal size facilitating storage and / or transport.

Accessoirement, en référence aux figures 3 et 5, le support de plaque suivant l'invention comporte une poignée (32) s'étendant au niveau de la partie médiane du corps central (11) depuis l'un des bords longitudinaux d'au moins l'une des plaques (12). Cette poignée (32) permet de transporter aisément le support de plaque en assurant un bon équilibre des masses.Incidentally, with reference to figures 3 and 5 , the plate support according to the invention comprises a handle (32) extending at the middle portion of the central body (11) from one of the longitudinal edges of at least one of the plates (12). This handle (32) can easily transport the plate support ensuring a good balance of masses.

Par ailleurs, le support de plaque suivant l'invention comporte des moyens de solidarisation du corps central (11) à l'extrémité supérieure de l'élément supérieur du mât central télescopique. Dans cet exemple particulier de réalisation, lesdits moyens de solidarisation consistent dans un manchon cylindrique (33) s'étendant dans la partie centrale de l'une des plaques (12) formant le corps central (11), ledit manchon s'étendant orthogonalement à ladite plaque (12), et dans lequel est apte à être emmanchée l'extrémité supérieure de l'élément supérieur du mât central télescopique d'un pied support, non représenté sur les figures.Furthermore, the plate support according to the invention comprises means for securing the central body (11) to the upper end of the upper element of the telescopic central mast. In this particular embodiment, said securing means consist of a cylindrical sleeve (33) extending in the central part of one of the plates (12) forming the central body (11), said sleeve extending orthogonally to said plate (12), and in which is adapted to be fitted the upper end of the upper element of the telescopic central mast of a support leg, not shown in the figures.

On observera que les moyens de solidarisation et/ou l'extrémité supérieure de l'élément supérieur du mât télescopique pourront comprendre des moyens aptes à procurer une inclinaison réglable du support de plaque sans pour autant sortir du cadre de l'invention.It will be observed that the securing means and / or the upper end of the upper element of the telescopic mast may comprise means capable of providing an adjustable inclination of the plate support without departing from the scope of the invention.

De plus, on notera que le support de plaque suivant l'invention pourra être monté sur tout type d'appareil « lève-plaque » sans sortir du cadre de l'invention.In addition, it will be noted that the plate support according to the invention may be mounted on any type of "lifting plate" device without departing from the scope of the invention.

Selon une variante d'exécution du support de plaque (7) suivant l'invention, en référence aux figures 7 à 9, ce dernier comporte de la même manière que précédemment un corps central (11) longitudinal constitué de deux plaques sensiblement rectangulaires (12) séparées par deux parois longitudinales (13) formant deux fourreaux centraux (14). Les fourreaux centraux (14) reçoivent respectivement un bras transversal (17) en forme général de T comprenant une branche médiane longitudinale (18) montée coulissante dans un fourreau (14) et une partie tubulaire transversale (19) soudée à l'extrémité libre de la branche médiane (18), ladite partie tubulaire transversale (19) s'étendant sensiblement dans le plan du corps central (11). Afin de régler la longueur de la branche médiane longitudinale (18) des bras transversaux faisant saillie des fourreaux (14), en fonction des dimensions de la plaque à porter, chaque branche médiane (18) comporte un doigt (20) coopérant avec un ressort et apte à être introduit dans des lumières (21) pratiquées le long de la branche médiane (18). Au moins l'une des parties tubulaires transversales (19) des bras transversaux comporte des butées d'arrêt (22) s'étendant orthogonalement par rapport auxdites parties tubulaires transversales (19) et aux branches médianes (18). Ces butées d'arrêt (22) sont positionnées symétriquement de part et d'autre de la branche médiane longitudinale (18), à proximité des extrémités libres de la partie tubulaire transversale (19) et sont destinées à recevoir le bord d'une plaque à poser verticalement, le support de plaque (7) étant alors orienté verticalement sur l'appareil « lève-plaque » non représenté sur les figures.According to an alternative embodiment of the plate support (7) according to the invention, with reference to the Figures 7 to 9 , the latter comprises in the same way as above a longitudinal central body (11) consisting of two substantially rectangular plates (12) separated by two longitudinal walls (13) forming two central sleeves (14). The central sleeves (14) respectively receive a generally T-shaped transverse arm (17) comprising a longitudinal central branch (18) slidably mounted in a sleeve (14) and a transverse tubular portion (19) welded to the free end of the middle branch (18), said transverse tubular portion (19) extending substantially in the plane of the central body (11). In order to adjust the length of the longitudinal middle branch (18) of the transverse arms projecting from the sleeves (14), depending on the dimensions of the plate to be carried, each middle branch (18) comprises a finger (20) cooperating with a spring and adapted to be introduced into lights (21) made along the middle branch (18). At least one of the transverse tubular portions (19) of the transverse arms has stopper stops (22) extending orthogonally with respect to said transverse tubular portions (19) and medial branches (18). These stops (22) are positioned symmetrically on either side of the longitudinal central branch (18), near the free ends of the transverse tubular portion (19) and are intended to receive the edge of a plate to pose vertically, the plate support (7) then being oriented vertically on the device "lifter plate" not shown in the figures.

Par ailleurs, le support de plaque (7) suivant l'invention comporte des bras transversaux articulés, deux bras (23) respectivement articulés autour d'un axe (24) solidaire des extrémités libres de joues (27) formées par les plaques (12) qui font saillies du corps central (11) et deux bras (25) respectivement articulés autour d'un axe (26) solidaire des extrémités libres de joues (27) formées par les plaques (12) qui font saillies du corps central (11).Furthermore, the plate support (7) according to the invention comprises articulated transverse arms, two arms (23) articulated respectively about an axis (24) integral with the free ends of cheeks (27) formed by the plates (12). ) which project from the central body (11) and two arms (25) articulated respectively about an axis (26) integral with the free ends of cheeks (27) formed by the plates (12) which project from the central body (11). ).

Des lumières curvilignes (28) sont pratiquées dans les joues (27). Ces lumières curvilignes (28) constituent des chemins de came dans lesquelles sont aptes à se déplacer des ergots (29), formant une came, solidaires des bras (23) et (25) de sorte que ces derniers sont aptes à se déplacer depuis une position repliée où les bras (23) et (25) s'étendent dans le long du corps central (11) jusqu'à une position dépliée où lesdits bras (23) et (25) s'étendent orthogonalement au corps central (11).Curvilinear lights (28) are formed in the cheeks (27). These curvilinear lights (28) constitute cam paths in which are able to move pins (29), forming a cam, integral with the arms (23) and (25) so that the latter are able to move from a folded position where the arms (23) and (25) extend in the long from the central body (11) to an unfolded position where said arms (23) and (25) extend orthogonally to the central body (11).

Cette variante d'exécution du support de plaque se distingue du support de plaque précédemment décrit par le fait qu'il comporte deux bras cintrés (34) s'étendant le long du corps central (11), sous ce dernier, de part et d'autre de l'axe longitudinal dudit corps central (11). Ces bras cintrés (34) sont reliés dans leur partie centrale par une entretoise (35) portant un volant (36) s'étendant entre l'entretoise (35) et le corps central (11). Sous l'entretoise (35) s'étend un manchon cylindrique (33) orthogonalement à la plaque (12), et dans lequel est apte à être emmanchée l'extrémité supérieure de l'élément supérieur du mât central télescopique d'un pied support, non représenté sur les figures. De cette manière, un opérateur peut aisément faire pivoter le support de plaque (7) autour de l'axe de révolution du manchon cylindrique (33) en actionnant le volant (36). On notera, par ailleurs, que les bras cintrés (34) forment des moyens de préhension permettant de transporter aisément le support de plaque tout en assurant un bon équilibre des masses.This variant embodiment of the plate support is distinguished from the previously described plate support by the fact that it comprises two bent arms (34) extending along the central body (11), under the latter, on both sides. other than the longitudinal axis of said central body (11). These bent arms (34) are connected in their central part by a spacer (35) carrying a wheel (36) extending between the spacer (35) and the central body (11). Under the spacer (35) extends a cylindrical sleeve (33) orthogonal to the plate (12), and in which is fitable to be fitted the upper end of the upper element of the telescopic central mast of a support leg , not shown in the figures. In this way, an operator can easily rotate the plate support (7) about the axis of revolution of the cylindrical sleeve (33) by actuating the flywheel (36). It should be noted, moreover, that the bent arms (34) form gripping means for easily transporting the plate support while ensuring a good balance of masses.

Enfin, il est bien évident que les exemples que l'on vient de donner ne sont que des illustrations particulières, en aucun cas limitatives quant aux domaines d'application de l'invention.Finally, it is obvious that the examples which have just been given are only particular illustrations, in no way limiting as to the fields of application of the invention.
