Description

L'invention concerne un dispositif d'étai et/ou de calage à développement télescopique, dénommé encore étai télescopique, à corps longiligne comportant une partie mâle ou montant, une partie femelle ou bras télescopique apte à coopérer par coulissement autour du montant, l'étai comprenant en outre des moyens d'actionnement pour engendrer le déploiement du bras.The invention relates to a forestay and / or rigging device with telescopic development, also called telescopic stay, elongated body having a male or rising portion, a female part or telescopic arm able to cooperate by sliding around the upright, the forestay further comprising actuating means for generating the deployment of the arm.

Dans divers métiers du bâtiment, il est utile de pouvoir étayer un plafond ou une paroi murale ou maintenir une menuiserie depuis une surface inférieure, de sorte à exercer une pression verticale ou angulaire.In various building trades, it is useful to be able to support a ceiling or a wall wall or maintain a joinery from a lower surface, so as to exert a vertical or angular pressure.

Par ailleurs, on cherche parfois à caler par une butée latérale des objets, notamment lors de leur transport. A cet effet, il est connu d'utiliser dans une autre fonction un étai qu'on dispose en pression entre le plancher et le plafond, et dont le corps vertical sert de surface d'appui latérale pour un objet.In addition, it is sometimes sought to wedge by a lateral abutment objects, especially during transport. For this purpose, it is known to use in another function a strut that is placed in pressure between the floor and the ceiling, and whose vertical body serves as a lateral support surface for an object.

Aussi, des étais connus présentent un corps longiligne et comprennent un bras télescopique dans la continuité du corps, chacune des extrémités distales du corps et du bras étant pourvue d'une surface d'appui. Le bras télescopique permet de s'adapter à la hauteur/distance entre le sol et la surface opposée d'appui. Une fois l'étai en place, celui-ci est maintenu en pression entre les deux surfaces, pouvant exercer sa fonction d'étai ou de moyen de butée latérale contre lequel peuvent être appuyés des objets.Also, known struts have an elongated body and comprise a telescopic arm in the continuity of the body, each of the distal ends of the body and the arm being provided with a bearing surface. The telescopic arm allows to adapt to the height / distance between the ground and the opposite surface of support. Once the forestay in place, it is maintained in pressure between the two surfaces, can exert its function of strut or means of lateral abutment against which objects can be supported.

Le bras télescopique de tels étais est généralement manoeuvrable par un système à crémaillère ou vis. Le système à crémaillère utilise une poignée qu'on presse afin de monter ou descendre le bras, tandis que le système à vis nécessite de visser ou dévisser un organe tournant.The telescopic arm of such props is generally manoeuvrable by a rack or screw system. The rack system uses a handle that is pressed to raise or lower the arm, while the screw system requires to screw or unscrew a rotating member.

Cependant, dans les deux systèmes ci-dessus, l'utilisateur a désavantageusement ses deux mains occupées, d'une part il maintient avec l'une de ses mains l'étai dans une position verticale ou inclinée, et d'autre part avec son autre main, il manoeuvre le système d'actionnement du bras télescopique pour amener en poussée l'extrémité dudit bras contre un plafond ou une paroi murale. Or, il est parfois utile de disposer de l'une de ses mains pour, concomitamment à la mise en place de l'étai, attraper ou maintenir un objet.However, in the two systems above, the user has disadvantageously both his hands occupied, on the one hand he holds with one of his hands the strut in a vertical or inclined position, and on the other hand with his Another hand, it operates the actuating system of the telescopic arm to push the end of said arm against a ceiling or wall. Now, it is sometimes useful to have one of his hands for, at the same time as setting up the forestay, catching or holding an object.

Par ailleurs, ces systèmes ne sont pas rapides de mise en oeuvre.Moreover, these systems are not fast to implement.

L'invention a donc pour but de proposer un dispositif d'étai et/ou de calage qui ne présente pas l'inconvénient majeur précité, permettant par conséquent de disposer d'une main libre lorsque le bras télescopique doit être déployé ou rangé (rétracté). En outre, les moyens mis en oeuvre pour autoriser les manoeuvres de déploiement ou rétraction sont avantageusement aisés et rapides.The invention therefore aims to provide a forestay and / or wedging device that does not have the aforementioned major drawback, thus allowing to have a free hand when the telescopic arm must be deployed or stored (retracted ). In addition, the means used to authorize deployment or retraction maneuvers are advantageously easy and fast.

Un autre but sera en particulier décrit, le même dispositif pouvant être aussi bien utilisé en tant qu'étai sur un sol plan, qu'en tant que moyen de calage latéral dans un véhicule disposant d'au moins un rail perforé pour la mise en place verticale du dispositif dans l'un des orifices dudit rail.Another object will be described in particular, the same device being able to be used both as a strut on a flat ground and as a lateral stalling means in a vehicle having at least one perforated rail for vertical position of the device in one of the orifices of said rail.

Selon l'invention, le dispositif d'étai et/ou de calage (dénommé étai) à développement télescopique présente un corps longiligne comportant une partie mâle ou montant (destiné à être posé sur le sol), une partie femelle ou bras télescopique apte à coopérer par coulissement autour du montant (destiné à être mis en appui contre la surface opposée au sol, plafond ou paroi murale), l'étai comprenant en outre des moyens d'actionnement pour engendrer le déploiement du bras, est caractérisé en ce que les moyens d'actionnement comportent un organe actionnable par le pied, du type pédale.According to the invention, the forestaying and / or wedging device (called forestay) with telescopic development has an elongate body comprising a male part or amount (intended to be placed on the ground), a female part or telescopic arm able to cooperate by sliding around the upright (intended to be pressed against the surface opposite the floor, ceiling or wall wall), the forestay further comprising actuating means for generating the deployment of the arm, is characterized in that the actuating means comprise a member actuatable by the foot, the pedal type.

L'organe d'actionnement commandé par le pied est apte à assurer le déblocage du bras en position fixe pour permettre son coulissement. L'organe d'actionnement permet aussi bien le déploiement du bras télescopique et son verrouillage en position que son déverrouillage et sa rétractation.The actuating member controlled by the foot is adapted to ensure the release of the arm in a fixed position to allow its sliding. The actuating member allows both the deployment of the telescopic arm and its locking in position that unlocking and retracting.

Par conséquent, grâce à l'organe d'actionnement par le pied, le dispositif posé sur le sol implique de n'utiliser qu'une seule main qui sert à tirer sur le bras télescopique pour le déployer, tandis que l'autre main reste libre.Therefore, thanks to the actuator by the foot, the device placed on the ground involves using only one hand that is used to pull the telescopic arm to deploy it, while the other hand remains free.

En outre, pour rétracter le bras télescopique, il suffit d'appuyer sur la pédale et le bras coulisse de lui-même, glissant seul par gravité.In addition, to retract the telescopic arm, simply press the pedal and the arm slides on its own, sliding alone by gravity.

A tout moment, s'il convient de le stopper à une hauteur donnée, il suffit de relâcher la pédale.At any time, if it should be stopped at a given height, simply release the pedal.

Le dispositif de l'invention, aisé d'utilisation est également rapide de mise en oeuvre.The device of the invention, easy to use is also fast implementation.

Dans la suite de la description le terme de « hauteur », les qualificatifs « supérieur », « inférieur », d'un élément du dispositif sont utilisés dans le cadre d'une installation du dispositif sur une surface horizontale, c'est-à-dire relatif à une notion verticale par rapport à un sol plat horizontal sur lequel serait posé le dispositif.In the remainder of the description, the term "height", the qualifiers "upper" and "lower", of an element of the device are used as part of an installation of the device on a horizontal surface, that is to say -say relative to a vertical concept with respect to a horizontal flat ground on which the device would be placed.

Les termes « interne » et « externe » qualifient les parties tournées respectivement vers l'intérieur et l'extérieur du dispositif.The terms "internal" and "external" qualify the parts facing respectively inwardly and outwardly of the device.

Le bras coulisse autour du montant avec très peu de jeu et selon un guidage parfait, en particulier grâce à deux embouts en matière plastique disposés pour l'un à l'extrémité supérieure et à l'intérieur du montant, et pour l'autre, autour du bras en son extrémité inférieure.The arm slides around the upright with very little clearance and with perfect guidance, in particular thanks to two plastic tips arranged for one at the upper end and inside the upright, and for the other, around the arm at its lower end.

Pour éviter que le bras ne puisse sortir hors du montant, soit lors du déploiement maximal soit lorsqu'il coulisse de lui-même pour être rangé, l'étai comporte des moyens de butées haute et basse pour le bras.To prevent the arm can not out of the amount, either during the maximum deployment or when sliding itself to be stored, the forestay has means for high and low stops for the arm.

Selon une caractéristique, le dispositif comporte des moyens de verrouillage coopérant avec le bras télescopique pour empêcher son coulissement, les moyens de verrouillage étant reliés à l'organe d'actionnement et l'actionnement dudit organe engendrant la dissociation des moyens de verrouillage avec le bras pour autoriser le coulissement de ce dernier.According to one characteristic, the device comprises locking means cooperating with the telescopic arm to prevent its sliding, the locking means being connected to the actuating member and the actuation of said member generating the disassociation of the locking means with the arm to allow the sliding of the latter.

De préférence, la coopération des moyens de verrouillage avec le bras télescopique se fait par frottement, les moyens de verrouillage présentant une surface d'appui mise en pression contre l'intérieur du bras creux, interdisant ainsi le coulissement du bras.Preferably, the cooperation of the locking means with the telescopic arm is by friction, the locking means having a bearing surface pressurized against the inside of the hollow arm, thus preventing the sliding of the arm.

Les moyens de verrouillage sont avantageusement associés au montant de l'étai, en particulier sont agencés à cheval de la paroi du montant de sorte à dépasser d'une part à l'intérieur du montant creux et d'autre part à l'extérieur du montant en direction de la paroi interne du bras entourant ledit montant.The locking means are advantageously associated with the amount of the strut, in particular are arranged astride the wall of the amount so as to exceed one hand inside the hollow amount and secondly to the outside of the amount in the direction of the inner wall of the arm surrounding said amount.

Selon une autre caractéristique, la pédale du dispositif est reliée aux moyens de verrouillage par un organe de transmission connecté à des moyens de manoeuvre qui coopèrent avec les moyens de verrouillage, ledit organe de transmission et lesdits moyens de manoeuvre étant logés à l'intérieur du montant. Lesdits moyens de manoeuvre sont aptes à être mobiles en réponse au déclenchement de l'organe d'actionnement (actionnement de la pédale).According to another characteristic, the pedal of the device is connected to the locking means by a transmission member connected to operating means which cooperate with the locking means, said transmission member and said operating means being housed inside the amount. Said operating means are able to be movable in response to the triggering of the actuating member (actuation of the pedal).

L'organe de transmission est avantageusement un fil d'acier de longueur adaptée à la hauteur du montant, lesdits moyens de manoeuvre étant agencés à proximité de l'extrémité distale supérieure du montant.The transmission member is advantageously a steel wire of length adapted to the height of the upright, said actuating means being arranged near the upper distal end of the upright.

De préférence, l'organe d'actionnement (la pédale) est disposée vers l'une des extrémités distales du corps (en partie inférieure du montant), à l'opposé du bras télescopique, et comprend une partie dite de commande qui est agencée à l'extérieur du corps de l'étai et sur laquelle l'utilisateur est destiné à appuyer, et une partie dite de liaison ou d'attache qui est située au moins en partie à l'intérieur du corps de l'étai.Preferably, the actuating member (the pedal) is disposed towards one of the distal ends of the body (at the bottom of the upright), opposite the telescopic arm, and comprises a so-called control portion which is arranged outside the forestay body and on which the user is intended to support, and a so-called connecting part or attachment which is located at least partly inside the body of the forestay.

La partie de la pédale agencée à l'intérieur du corps de l'étai est rendue solidaire des moyens de transmission.The part of the pedal arranged inside the forestay body is secured to the transmission means.

Avantageusement, la pédale, plus particulièrement la partie de commande de la pédale, est pliable et destinée hors utilisation à être disposée parallèlement et le long du corps de l'étai.Advantageously, the pedal, more particularly the control part of the pedal, is foldable and intended out of use to be arranged parallel and along the body of the forestay.

Selon une autre caractéristique, l'étai comporte en outre une allonge supplémentaire manoeuvrable par vissage/dévissage, permettant d'ajuster au mieux la pression que doit exercer l'étai. De préférence, l'allonge est agencée à l'extrémité distale inférieure de l'étai (extrémité du montant). En variante, elle pourrait être associée à l'extrémité distale supérieure de l'étai (extrémité du bras).According to another characteristic, the strut further comprises an additional extension which can be operated by screwing / unscrewing, making it possible to adjust the pressure that the strut must exert as well as possible. Preferably, the elongate is arranged at the lower distal end of the strut (end of the upright). Alternatively, it could be associated with the upper distal end of the strut (end of the arm).

Selon une caractéristique préférentielle, le corps du dispositif ou le montant et/ou le bras sont à section parallélépipédique plutôt que circulaire afin de faciliter la préhension du dispositif, voire conférer une meilleure préhension qu'un corps à section circulaire, en particulier lorsqu'il s'agit de visser ou dévisser l'allonge.According to a preferred feature, the body of the device or the upright and / or the arm are of parallelepipedal rather than circular section in order to facilitate gripping of the device, or even to confer a better grip than a circular section body, particularly when This is to screw or unscrew the elongated.

Selon une autre caractéristique avantageuse de l'étai, celui-ci comprend deux pieds, chacun à une extrémité distale du corps pour assurer sa fonction, chaque pied étant destiné à coopérer avec une surface d'accueil (sol et plafond ou paroi murale), au moins l'un des pieds, de préférence les deux, comprenant une surface d'appui de configuration interchangeable, l'une des configurations étant de forme à surface plane, tandis que l'autre configuration est à embout cylindrique.According to another advantageous characteristic of the strut, it comprises two feet, each at a distal end of the body to perform its function, each foot being intended to cooperate with a receiving surface (floor and ceiling or wall), at least one of the feet, preferably both, comprising a support surface of interchangeable configuration, one of the configurations having a flat surface shape, while the other configuration is cylindrical.

Le pied dont la surface d'appui est à configuration interchangeable est de préférence à fonction réversible, et comporte une tige à embout cylindrique et un patin à surface plane fixé par pivotement autour de la tige réversible, notamment dont l'une des configurations est de forme à surface plane, tandis que l'autre configuration est à embout cylindrique.The foot whose bearing surface is of interchangeable configuration is preferably reversible, and comprises a rod with a cylindrical tip and a flat surface pad pivotally fixed around the reversible rod, in particular one of which is flat shape, while the other configuration is cylindrical.

Une variante avec des formes amovibles pourrait être envisagée mais n'est pas préférée.A variant with removable shapes could be considered but is not preferred.

Ainsi, on peut avec le même étai proposer au choix deux types de surfaces d'appui, la configuration à embout cylindrique permettant en particulier de coopérer avec un orifice de rail généralement disposé dans des véhicules de transport.Thus, it is possible with the same two to offer two types of bearing surfaces, the cylindrical tip configuration in particular to cooperate with a rail hole generally disposed in transport vehicles.

Un tel pied à fonction réversible comporte une tige à embout cylindrique et un patin à surface plane, la surface plane étant en saillie de l'embout dans l'une des configurations, et inversement dans l'autre configuration, l'embout cylindrique dépassant du patin. Le passage de l'une à l'autre des configurations est obtenu en retournant à 180° le patin, par exemple par pivotement, le patin et/ou la tige étant doté de moyens de blocage en rotation du type bossage pour éviter que le patin ne soit libre de pivoter.Such a reversible function foot comprises a cylindrical tip rod and a flat surface shoe, the flat surface projecting from the end piece in one of the configurations, and conversely in the other configuration, the cylindrical end protruding from the skate. The passage from one to the other of the configurations is obtained by returning the pad to 180 °, for example by pivoting, the pad and / or the rod being provided with rotation locking means of the boss type to prevent the pad is free to rotate.

Par ailleurs, les deux pieds du dispositif comportent donc chacun un patin ou une semelle, ce patin étant avantageusement inclinable et apte à être maintenu en position. Grâce à l'axe de pivotement du patin décrit plus haut, celui-ci peut être pivoté de manière à l'incliner à l'angle voulu lorsque l'étai nécessite d'être appliqué contre une paroi murale. De plus, le patin peut comporter deux orifices de fixation lorsqu'il s'agit de maintenir fermement l'étai en place et le fixer aux surfaces d'accueil.Moreover, the two feet of the device therefore each comprise a pad or a sole, this pad being advantageously inclinable and able to be held in position. Thanks to the pivot axis of the pad described above, it can be pivoted so as to tilt to the desired angle when the strut requires to be applied against a wall wall. In addition, the pad may have two mounting holes when it comes to firmly hold the forestay in place and attach it to the reception surfaces.

Les figures 1 et 2 illustrent un étai télescopique 1 selon l'invention respectivement en position rétractée et en position déployée.The Figures 1 and 2 illustrate a telescopic stay 1 according to the invention respectively in the retracted position and in the deployed position.

Cet étai des figures 1 et 2 est destiné à être utilisé et mis en pression entre deux surfaces d'accueil et d'appui planes (non représentées), l'application visée étant celle d'un étai en tant que tel. Aussi, les extrémités distales de l'étai 4A et 4B (dénommées ci-après pieds) présentent des surfaces à extension plane.This forestay Figures 1 and 2 is intended to be used and pressurized between two flat reception and support surfaces (not shown), the intended application being that of a forestay as such. Also, the distal ends of the strut 4A and 4B (hereinafter referred to as feet) have flat surfaces.

Le même étai illustré sur la figure 3a est en revanche plus particulièrement destiné mais pas exclusivement à constituer un moyen de calage latéral tel que lors de transport d'objets dans un véhicule. Par conséquent, au moins l'une des extrémités ou pied 4A de l'étai est dotée d'une surface à forme cylindrique pour coopérer mutuellement avec une surface d'accueil du type perforée d'un rail 10. Dans cette utilisation, un rail est disposé sur le plancher du véhicule et de préférence un autre rail est agencé sur le plafond ; l'étai est mis en place dans le rail inférieur via l'engagement de son extrémité cylindrique inférieure dans un orifice dudit rail, tandis que son extrémité opposée cylindrique supérieure est introduite en déployant le bras pour s'engager dans un orifice du rail supérieur, le corps de l'étai pouvant alors servir de butée latérale contre laquelle est appuyé un objet à transporter. Bien entendu, en l'absence de rail supérieur, l'extrémité supérieure du bras pourrait présenter la forme de la semelle plate 4B de la figure 2 pour se plaquer contre le plafond.The same was illustrated on the figure 3a on the other hand is more particularly intended but not exclusively to constitute a lateral locking means such as when transporting objects in a vehicle. Therefore, at least one of the ends or feet 4A of the strut is provided with a cylindrically shaped surface to mutually cooperate with a receiving surface of the perforated type of a rail 10. In this use, a rail is disposed on the floor of the vehicle and preferably another rail is arranged on the ceiling; the strut is put in place in the lower rail via the engagement of its lower cylindrical end in an orifice of said rail, while its opposite upper cylindrical end is introduced by unfolding the arm to engage in an opening of the upper rail, the forestay body can then serve as a lateral stop against which is supported an object to be transported. Of course, in the absence of an upper rail, the upper end of the arm could have the shape of the flat sole 4B of the figure 2 to press against the ceiling.

Comme il sera vu plus loin, le même étai 1 de l'invention comporte avantageusement les deux types de surface, à extension plane formant un patin d'une part et à bout cylindrique d'autre part, l'une des surfaces étant disposée sélectivement en tant que surface d'appui selon l'utilisation qui est faite de l'étai.As will be seen below, the same strut 1 of the invention advantageously comprises the two types of surface, with planar extension forming a pad on the one hand and cylindrical toe on the other hand, one of surfaces being selectively disposed as a bearing surface according to the use of the stay.

En regard des figures 1 et 2, l'étai 1 comporte un corps longiligne doté d'un montant 2 formant une embase longitudinale pour l'étai, et d'un bras télescopique 3 apte à se déployer au-delà du montant 2 selon le même axe longitudinal.With regard to Figures 1 and 2 , the strut 1 comprises an elongate body with an amount 2 forming a longitudinal base for the strut, and a telescopic arm 3 adapted to extend beyond the upright 2 along the same longitudinal axis.

Le bras télescopique 3 est creux et forme une partie femelle du corps de l'étai, tandis que le montant 2 forme une partie mâle, la partie femelle ou bras 3 étant apte à coulisser autour du montant 2 pour être déployée à la hauteur souhaitée (figure 2). En position rétractée du bras 3, la partie mâle 2 est complètement engagée dans la partie femelle 3 (figure 1).The telescopic arm 3 is hollow and forms a female part of the forestay body, while the upright 2 forms a male part, the female part or arm 3 being able to slide around the upright 2 to be deployed at the desired height ( figure 2 ). In the retracted position of the arm 3, the male part 2 is completely engaged in the female part 3 ( figure 1 ).

A titre d'exemple non limitatif, la longueur de l'étai en position rétractée est de 1,5 m et en position déployée maximale de 2,65 m comprenant 10 cm d'allonge par vissage.By way of non-limiting example, the length of the forestay in the retracted position is 1.5 m and in the maximum extended position of 2.65 m comprising 10 cm of extension by screwing.

Un jeu existe entre le bras 3 et le montant 2 pour permettre le coulissement. En outre, des moyens de verrouillage internes au corps de l'étai et décrits plus loin permettent de bloquer le coulissement du bras 3.A game exists between the arm 3 and the amount 2 to allow sliding. In addition, internal locking means to the forestay body and described below make it possible to block the sliding of the arm 3.

Bien entendu des butées haute et basse sont prévues associées au corps de l'étai pour éviter que le bras 3 ne coulisse intempestivement au-delà des deux extrémités libres supérieure 2B et inférieure 2A du montant 2. Ces butées sont décrites plus loin.Of course, high and low stops are provided associated with the forestay body to prevent the arm 3 from sliding unexpectedly beyond the two upper free ends 2B and lower 2A of the upright 2. These stops are described below.

Par ailleurs, l'étai 1 comporte une tige filetée 5A apte à être vissée/dévissée pour former une allonge supplémentaire à l'étai afin d'ajuster précisément si besoin la hauteur d'extension de l'étai, et donc la hauteur de déploiement du bras 3 afin de réaliser la mise en pression parfaite du dispositif au niveau de ses parties supérieure et inférieure et ainsi assurer sa fonction d'étai.Furthermore, the strut 1 comprises a threaded rod 5A adapted to be screwed / unscrewed to form an additional extension to the strut in order to precisely adjust if necessary the extension height of the strut, and therefore the deployment height arm 3 to achieve the perfect pressurization of the device at its upper and lower parts and thus ensure its strut function.

La tige 5A est de préférence disposée dans la partie inférieure de l'étai, au niveau de l'extrémité inférieure 2A du montant 2 et en saillie de celui-ci. L'association de la tige 5A au montant 2 sera décrite ultérieurement en regard de la figure 4.The rod 5A is preferably arranged in the lower part of the forestay, at the lower end 2A of the upright 2 and projecting therefrom. The association of the rod 5A with the amount 2 will be described later with regard to the figure 4 .

L'étai 1 comporte également, tel que vu plus haut, deux pieds 4A et 4B pour servir de surfaces d'appui respectivement inférieure et supérieure à l'étai. Les pieds sont respectivement associés aux extrémités distales du corps, en particulier respectivement à la tige 5A en prolongement du montant 2 et au bras 3 via une tige 5B.The strut 1 also comprises, as seen above, two legs 4A and 4B to serve as bearing surfaces respectively lower and higher than the strut. The feet are respectively associated with the distal ends of the body, in particular respectively with the rod 5A in extension of the upright 2 and the arm 3 via a rod 5B.

Enfin, l'étai 1 comporte un organe d'actionnement 6 sur lequel est destiné à agir l'utilisateur pour déployer/rétracter le bras 3.Finally, the stay 1 comprises an actuating member 6 on which is intended to act the user to deploy / retract the arm 3.

Selon l'invention, l'organe d'actionnement 6 est actionnable par le pied de l'utilisateur. Il se présente sous la forme d'une pédale.According to the invention, the actuating member 6 is actuable by the user's foot. It comes in the form of a pedal.

La pédale 6 est agencée au niveau de l'extrémité inférieure du corps de l'étai, en particulier associée à l'extrémité inférieure du montant 2.The pedal 6 is arranged at the lower end of the strut body, in particular associated with the lower end of the upright 2.

Hors actionnement de la pédale, le bras 3 ne peut pas coulisser. Pour agir sur le déploiement ou la rétractation du bras 3 et par conséquent permettre son coulissement autour du montant 2, il est nécessaire d'appuyer sur la pédale 6.Without actuation of the pedal, the arm 3 can not slide. To act on the deployment or retraction of the arm 3 and consequently allow it to slide around the upright 2, it is necessary to press the pedal 6.

La pédale 6 est apte à agir sur des moyens de verrouillage/déverrouillage 7 qui seront décrits plus en détail au regard des figures 5, 6a et 6b. Les moyens de verrouillage/déverrouillage 7 sont d'une part associés au montant 2 et d'autre part destinés à coopérer avec le bras 3 en position de blocage du bras 3 autour du montant 2. Lorsque l'on appuie sur la pédale 6, celle-ci agit en déverrouillant les moyens de verrouillage 7 qui ne coopèrent plus avec le bras 3, ce qui permet le coulissement dudit bras le long du montant 2. Lorsqu'à nouveau, on n'appuie plus sur la pédale 6, les moyens de verrouillage 7 coopèrent à nouveau avec le bras 3, bloquant son coulissement et maintenant le bras autour du montant 2 à la hauteur à laquelle on a relâché la pédale.The pedal 6 is able to act on locking / unlocking means 7 which will be described in more detail with regard to the Figures 5, 6a and 6b . The locking / unlocking means 7 are on the one hand associated with the upright 2 and on the other hand intended to cooperate with the arm 3 in the locked position of the arm 3 around the upright 2. When the pedal 6 is depressed, it acts by unlocking the locking means 7 which no longer cooperate with the arm 3, which allows the sliding of said arm along the upright 2. When again, it no longer presses on the pedal 6, the means locking 7 cooperate again with the arm 3, blocking its sliding and now the arm around the upright 2 at the height at which the pedal was released.

Dans l'exemple préféré de l'invention et décrit ci-après, la coopération des moyens de verrouillage 7 avec le bras 3 se fait par frottement (figure 5 et 6a), les moyens de verrouillage 7 présentant une surface d'appui 70 mise en pression contre la face interne 31 de la paroi 30 du bras creux 3, interdisant le coulissement du bras.In the preferred example of the invention and described below, the cooperation of the locking means 7 with the arm 3 is by friction ( Figure 5 and 6a ), the locking means 7 having a bearing surface 70 pressurized against the inner face 31 of the wall 30 of the hollow arm 3, preventing the sliding of the arm.

En regard des figures 4 et 5, la pédale 6 est reliée aux moyens de verrouillage 7 par un organe de transmission 8 (sous la forme d'un fil d'acier) et des moyens de manoeuvre 9 qui sont mobiles en réponse à l'actionnement de la pédale. Plus précisément, l'organe de transmission 8 est connecté à la pédale 6 d'une part et aux moyens de manoeuvre 9 d'autre part ; en appuyant sur la pédale 6, l'organe de transmission 8 commande le mouvement des moyens de manoeuvre 9 qui par leur mobilité, se désengagent des moyens de verrouillage 7 ou au moins n'appuient plus par pression sur lesdits moyens 7.With regard to figures 4 and 5 the pedal 6 is connected to the locking means 7 by a transmission member 8 (in the form of a steel wire) and actuating means 9 which are movable in response to the actuation of the pedal. More specifically, the transmission member 8 is connected to the pedal 6 on the one hand and the operating means 9 on the other hand; by pressing the pedal 6, the transmission member 8 controls the movement of the operating means 9 which, by their mobility, disengage from the locking means 7 or at least no longer pressurize said means 7.

L'organe de transmission 8 (figure 5) est un fil d'acier rendu solidaire de la pédale de commande 6 et s'étendant sur toute la hauteur du montant 2 jusqu'aux moyens de manoeuvre 9 qui sont fixés à la partie supérieure creuse 2B du montant 2.The transmission member 8 ( figure 5 ) is a steel wire secured to the control pedal 6 and extending over the entire height of the upright 2 to the operating means 9 which are fixed to the hollow upper portion 2B of the upright 2.

En regard de la figure 5, les moyens de manoeuvre 9 comportent :

  • une pièce en U 90 dont les ailes parallèles 90A et 90B sont rivetées à la paroi du montant 2 et dont l'âme 90C est agencée perpendiculairement à l'axe longitudinal du montant ;
  • un ressort 91 à spirales reposant par sa partie inférieure sur l'âme 90C et butant par sa partie supérieure contre une goupille 91A solidaire transversalement d'une pièce centrale le ressort 91 est en compression précontrainte dans cette position ;
  • une pièce centrale 92 formant un plat oblong qui s'étend longitudinalement au montant, traverse l'âme 90C du U 90, et est maintenu en place grâce au ressort 91 qui l'enserre, le plat 92 présentant une portion supérieure 92A dépassant du ressort. La partie inférieure 92B de la pièce centrale 92 s'étendant au-delà du U, en direction du bas du montant 2 est rendue solidaire de l'organe de transmission 8 ;
  • un galet 93 fixé à la portion supérieure 92A de la pièce centrale 92 et à rotation libre.
With regard to the figure 5 the operating means 9 comprise:
  • a U-shaped part 90 whose parallel flanges 90A and 90B are riveted to the wall of the upright 2 and whose core 90C is arranged perpendicularly to the longitudinal axis of the upright;
  • a spring 91 with spirals resting at its lower part on the core 90C and abutting by its upper part against a pin 91A transversely integral with a central part the spring 91 is in prestressing compression in this position;
  • a central piece 92 forming an oblong plate which extends longitudinally to the upright, passes through the core 90C of the U 90, and is held in place by the spring 91 which surrounds it, the plate 92 having an upper portion 92A protruding from the spring . The lower part 92B of the central part 92 extending beyond the U, towards the bottom of the upright 2 is made integral with the transmission member 8;
  • a roller 93 fixed to the upper portion 92A of the central piece 92 and free rotation.

Les moyens de verrouillage 7 forment deux cales en regard et prisonnières de la paroi 20 du montant 2. Les cales sont logées à cheval de la paroi de sorte à dépasser d'une part à l'intérieur du montant creux 2 et d'autre part à l'extérieur du montant.The locking means 7 form two wedges opposite and trapped in the wall 20 of the upright 2. The wedges are mounted astride the wall so as to protrude on the one hand inside the hollow upright 2 and on the other hand outside the amount.

En regard des figures 5 et 6a, la face externe 70 des cales, située à l'extérieur du montant 2, est plane et parallèle à la face interne 31 de la paroi du bras creux 3, et est destinée à s'appuyer contre ladite paroi en position de blocage.With regard to Figures 5 and 6a , the outer face 70 of the wedges, located outside the upright 2, is flat and parallel to the inner face 31 of the wall of the hollow arm 3, and is intended to bear against said wall in the locking position.

La face interne 71 des pièces, située à l'intérieur du montant 2, est plane et biseautée ménageant un espace entre les deux pièces allant en s'élargissant du haut 72 vers le bas 73 des cales, c'est-à-dire en direction de la partie inférieure du montant.The internal face 71 of the parts, located inside the upright 2, is flat and bevelled, providing a space between the two parts widening from the top 72 to the bottom 73 of the shims, that is to say in direction of the lower part of the amount.

Le galet 93 des moyens de manoeuvre 9 est disposé en regard et contre les cales 7 et porte contre les faces internes 71 de ces dernières.The roller 93 of the operating means 9 is arranged opposite and against the wedges 7 and bears against the inner faces 71 of the latter.

En position de relâche de la pédale 6 (figures 5 et 6a), l'organe de transmission 8 n'étant pas en traction, le ressort 91 reste précontraint, la pièce centrale 92 est dans sa position haute et le galet 93 est agencé au niveau de la partie supérieure 72 des cales 7, c'est-à-dire au niveau de la largeur d'écartement entre les faces internes 71 qui est la plus étroite. Le galet 93 exerce alors une pression contre les faces internes 71, engendrant le placage des faces externes 70 des cales 7 contre la face interne 31 de la paroi du bras 3, ce qui supprime, à cette hauteur du corps de l'étai, tout jeu entre le bras 3 et le montant 2, bloquant en position le bras 3.In the release position of the pedal 6 ( Figures 5 and 6a ), the transmission member 8 not being in tension, the spring 91 remains prestressed, the central piece 92 is in its high position and the roller 93 is arranged at the upper part 72 of the wedges 7, it is that is to say at the width of the spacing between the internal faces 71 which is the narrowest. The roller 93 then exerts a pressure against the inner faces 71, causing the external faces 70 of the wedges 7 to be pressed against the internal face 31 of the wall of the arm 3, which removes, at this height from the body of the strut, all play between the arm 3 and the upright 2, blocking the arm 3 in position.

En position d'actionnement de la pédale 6 (figure 6b), l'organe de transmission 8 est alors en traction, entraînant le mouvement du plat 92 et la descente du galet 93 vers la partie 73 la plus large de séparation des deux faces internes 71 des cales 7, jusqu'à ne plus exercer de pression contre lesdites faces, engendrant le dégagement des faces externes 70 des cales 7, de la face interne 31 de la paroi du bras 3. Ceci autorise un jeu 74 entre la paroi du bras 3 et le montant 2 pour permettre le coulissement. Le bras 3 peut alors coulisser librement. Le jeu 74 est représenté exagéré sur la figure 6b qui n'est pas à l'échelle pour une meilleure compréhension.In the position of actuation of the pedal 6 ( figure 6b ), the transmission member 8 is then in traction, causing the movement of the plate 92 and the descent of the roller 93 towards the widest part of separation of the two inner faces 71 of the wedges 7, until no longer exerting pressure against said faces, causing the release of the outer faces 70 of the wedges 7, the inner face 31 of the wall of the arm 3. This allows a clearance 74 between the wall of the arm 3 and the upright 2 to allow sliding. The arm 3 can then slide freely. The game 74 is represented exaggerated on the figure 6b which is not scaled for better understanding.

Dès que l'on relâche la pédale 6, sous l'effet du ressort 91 qui n'est plus comprimé et se détend, le plat 92 remonte, translatant le galet 93 vers le haut, qui à nouveau exerce une pression sur les cales 7, ces dernières se plaquant à nouveau contre la paroi du bras 3, verrouillant le coulissement du bras.As soon as the pedal 6 is released, under the effect of the spring 91 which is no longer compressed and relaxes, the plate 92 rises, translating the roller 93 upwards, which again exerts a pressure on the wedges 7 , the latter pressing against the wall of the arm 3 again, locking the sliding of the arm.

En regard de la figure 4, la pédale 6 comporte une partie d'attache 60 associée au montant 2, et une partie d'appui ou de commande 61 reliée à la partie d'attache 60.With regard to the figure 4 , the pedal 6 comprises a fastening portion 60 associated with the upright 2, and a bearing or control portion 61 connected to the fastening portion 60.

La partie d'attache 60 est fixée (en rotation d'axe transversal) à une pièce 21 insérée dans le montant 2, et rivetée à l'extrémité libre inférieure 2A dudit montant. En outre, elle fait légèrement saillie en prolongement du montant 2 (figure 7) de manière à permettre le dégagement de la partie de commande 61 en dehors du montant.The attachment portion 60 is fixed (in rotation of transverse axis) to a part 21 inserted in the upright 2, and riveted to the lower free end 2A of said upright. In addition, it protrudes slightly in extension of the amount 2 ( figure 7 ) so as to allow the release of the control portion 61 outside the amount.

En regard de la figure 4, la partie de commande 61 est orientée sensiblement perpendiculairement à l'axe du montant pour opérer son actionnement.With regard to the figure 4 , the control portion 61 is oriented substantially perpendicular to the axis of the amount to operate its operation.

Avantageusement, la pédale 6 est repliable pour s'étendre parallèlement au montant 2 tel que visible sur la figure 7 afin de ne pas gêner l'espace autour de l'étai en position d'utilisation, ou en particulier lorsqu'il convient de tourner l'étai pour ajuster la pression, afin que la pédale ne bute pas dans un objet à caler ou un mur. La partie de commande 61 est ainsi connectée à la partie d'attache 60 par un axe de pivotement 62.Advantageously, the pedal 6 is foldable to extend parallel to the amount 2 as visible on the figure 7 so as not to disturb the space around the forestay in position of use, or in particular when it is necessary to turn the forestay to adjust the pressure, so that the pedal does not stop in a stall object or a wall. The control portion 61 is thus connected to the attachment portion 60 by a pivot axis 62.

Au regard de l'ajustement de la hauteur de l'étai grâce à la tige inférieure 5A filetée (figures 1, 2 et 4), la tige filetée 5A est associée à la pièce 21 du montant 2, la traversant de part en part. Un écrou 50 est maintenu fixe sur cette pièce 21 en étant pris en sandwich entre une partie basse 21A et une partie haute 21B de la pièce 21. La tige filetée 5A peut ainsi être dévissée pour s'étendre bien au-delà de l'extrémité libre inférieure 2A du montant 2, tel qu'illustré sur la figure 2, et ainsi allonger encore l'étai, ou bien être revissée pour être introduite à nouveau à l'intérieur du montant (figure 1). La tige filetée 5A présente une longueur limitée à l'utilisation qui en est faite, c'est-à-dire à l'ajustement de la hauteur. Sa longueur permet par exemple une allonge de l'ordre de 100 mm. A noter que la tige n'est pas forcément filetée sur toute sa longueur.With regard to the adjustment of the height of the forestay thanks to the threaded lower rod 5A ( Figures 1, 2 and 4 ), the threaded rod 5A is associated with the part 21 of the upright 2, passing right through it. A nut 50 is held fixed on this part 21 by being sandwiched between a lower part 21A and an upper part 21B of the part 21. The threaded rod 5A can thus be unscrewed to extend well beyond the end lower free 2A of the amount 2, as shown on the figure 2 , and thus further lengthen the forestay, or be screwed again to be introduced again inside the stud ( figure 1 ). The threaded rod 5A has a length limited to the use made of it, that is to say the height adjustment. Its length allows for example an elongation of the order of 100 mm. Note that the stem is not necessarily threaded over its entire length.

Enfin, les pieds 4A et 4B de l'étai 1 de l'invention sont adaptables à la surface d'accueil avec laquelle l'étai est destiné à coopérer.Finally, the feet 4A and 4B of the strut 1 of the invention are adaptable to the receiving surface with which the strut is intended to cooperate.

En regard des figures 1 et 2, le pied inférieur 4A est associé à l'extrémité distale de la tige filetée 5A opposée à celle logée dans le montant 2. Le pied supérieur 4B est solidaire de l'extrémité distale de la tige supérieure 5B fixée à l'extrémité libre supérieure du bras 3.With regard to Figures 1 and 2 , the lower leg 4A is associated with the distal end of the threaded rod 5A opposite that housed in the upright 2. The upper leg 4B is secured to the distal end of the upper rod 5B fixed to the upper free end of the arm 3.

Selon l'invention, au moins le pied inférieur 4A, et de préférence chaque pied 4A, 4B est réversible, c'est-à-dire qu'il comporte deux configurations distinctes pouvant être sélectivement mis en place pour former la surface d'appui ad hoc de l'étai.According to the invention, at least the lower leg 4A, and preferably each foot 4A, 4B is reversible, that is to say it comprises two separate configurations that can be selectively put in place to form the ad hoc support surface of the stay.

En regard de la figure 8a qui illustre par exemple le pied supérieur 4B le pied comporte un patin 40 dont la semelle forme une surface plane 42. Le patin 40 est monté sur un axe de pivotement 41 transversal à la tige 5B afin de pouvoir pivoter à 180°. Pour ne pas que le patin 40 pivote librement, il comporte un bossage 43 coopérant avec la tige 5B afin de former un point de résistance à la rotation, sans bloquer cette dernière. Il est ainsi nécessaire de forcer le point de résistance pour retourner le patin. Une fois la rotation de 180° effectuée, le bossage rencontre à nouveau la tige, bloquant en position le patin.With regard to the figure 8a which illustrates for example the upper foot 4B the foot has a shoe 40 whose sole forms a flat surface 42. The shoe 40 is mounted on a pivot axis 41 transverse to the rod 5B in order to rotate 180 °. So as not that the pad 40 pivots freely, it comprises a boss 43 cooperating with the rod 5B to form a resistance point to the rotation, without blocking the latter. It is thus necessary to force the point of resistance to return the pad. Once the rotation of 180 ° carried out, the boss meets the rod again, blocking in position the pad.

Lorsque la surface plane 42 du patin est tournée vers l'environnement extérieur à l'opposé du montant, ladite surface est en saillie de la tige 5B (figure 8a). Au contraire, lorsque le patin a été pivoté (figure 8b), la tige 5B présente son extrémité libre 51 en saillie du patin de sorte à former la surface d'appui à embout cylindrique et permettre une coopération avec un orifice du rail 10 (figure 3b).When the flat surface 42 of the pad is turned towards the external environment opposite the upright, said surface is projecting from the rod 5B ( figure 8a ). On the contrary, when the pad has been rotated ( figure 8b ), the rod 5B has its free end 51 projecting from the pad so as to form the cylindrical end bearing surface and allow a cooperation with an orifice of the rail 10 ( figure 3b ).

Enfin, les figures 9 et 10 illustrent les moyens de butée associés respectivement aux parties distales supérieure et inférieure du bras télescopique 3 pour éviter que celui-ci ne puisse être démanché du montant 2.Finally, Figures 9 and 10 illustrate the abutment means associated respectively with the distal upper and lower portions of the telescopic arm 3 to prevent it from being disconnected from the upright 2.

En regard de la figure 9, le bras 3 comprend dans sa cavité à son extrémité supérieure un embout 32, tandis que le montant 2 comporte à son extrémité distale et également dans sa cavité un autre embout 23. Lorsque le bras est totalement rétracté, l'embout 32 du bras 3 vient en applique contre l'embout 23 du montant 2 empêchant le bras vient en applique contre l'embout 23 du montant 2 empêchant le bras télescopique de descendre davantage. Pour éviter un plaquage direct des deux surfaces des embouts 32 et 23, il est préféré de doter la face inférieure de l'embout 32 du bras 3 de picots 33 faisant saillie en direction du montant 2.With regard to the figure 9 , the arm 3 comprises in its cavity at its upper end a tip 32, while the upright 2 has at its distal end and also in its cavity another tip 23. When the arm is fully retracted, the tip 32 of the arm 3 comes to apply against the tip 23 of the amount 2 preventing the arm is applied against the tip 23 of the upright 2 preventing the telescopic arm to go down further. To avoid a direct plating of the two surfaces of the end pieces 32 and 23, it is preferred to provide the lower face of the end piece 32 of the arm 3 with pins 33 projecting towards the upright 2.

En regard de la figure 10, pour éviter que le bras 3 ne se déploie au-delà de l'extrémité supérieure 2B du montant 2, le bras 3 comporte dans sa partie distale inférieure 3A, des butées en regard 34 logées à l'intérieur du bras en étant plaquées contre la face interne 31 de la paroi 30 du bras. Elles sont rendues solidaires par clipsage de pattes 35 dans des fenêtres 36 de la paroi du bras 3. Par leur chant supérieur 37, elles viennent buter contre la tranche inférieure 75 des cales 7 du montant 2.With regard to the figure 10 to prevent the arm 3 from extending beyond the upper end 2B of the upright 2, the arm 3 has in its lower distal portion 3A, abutting stops 34 housed inside the arm being pressed against the inner face 31 of the wall 30 of the arm. They are made integral by clipping tabs 35 in windows 36 of the wall of the arm 3. By their upper edge 37, they abut against the lower edge 75 of the wedges 7 of the upright 2.

Le fonctionnement du dispositif de l'invention est à présent décrit.The operation of the device of the invention is now described.

L'étai est par exemple dans sa configuration repliée telle que visible sur la figure 1.The strut is for example in its folded configuration as visible on the figure 1 .

Lorsque l'utilisateur souhaite le déplier, il pose le montant 2 à la verticale en le maintenant d'une seule main sur le pied 5A dudit montant.When the user wishes to unfold it, it raises the upright 2 by holding it with one hand on the foot 5A of said amount.

L'utilisateur appuie ensuite sur la partie de commande 61 de la pédale 6 avec son pied permettant de déverrouiller les moyens de verrouillage 7.The user then presses the control portion 61 of the pedal 6 with his foot to unlock the locking means 7.

L'utilisateur peut alors déployer le bras 3 avec sa main qui au départ maintenait le dispositif verticalement, tandis que son autre main est libre.The user can then deploy the arm 3 with his hand which initially held the device vertically, while his other hand is free.

L'utilisateur tire sur le bras 3 jusqu'à la hauteur voulue. Il stoppe alors le déploiement et verrouille le bras 3 en position en relâchant la pédale.The user pulls the arm 3 to the desired height. It then stops the deployment and locks the arm 3 in position by releasing the pedal.

La partie de commande 61 de la pédale 6 peut être avantageusement repliée.The control portion 61 of the pedal 6 can be advantageously folded.

Enfin, s'il convient d'ajuster la pression exercée par l'étai, l'utilisateur se saisit à sa hauteur de l'étai (c'est possible d'une seule main) et tourne de manière à dévisser la tige filetée 5A pour augmenter légèrement la hauteur de l'étai.Finally, if it is necessary to adjust the pressure exerted by the strut, the user grasps at its height of the strut (it is possible with one hand) and turns to unscrew the threaded rod 5A to slightly increase the height of the forestay.

Lorsque l'utilisateur souhaite ranger l'étai, il suffit qu'il appuie sur la pédale 6, le bras 3 redescend en coulissant directement par gravité. La tige filetée peut être revissée à tout moment.When the user wants to store the forestay, it is sufficient that he presses the pedal 6, the arm 3 descends by sliding directly by gravity. The threaded rod can be screwed again at any time.
