Description

La présente invention concerne des perfectionnements apportés aux agencements de solidarisation pour, dans un échafaudage, assembler à un mât au moins un élément, tel qu'une traverse ou analogue, s'étendant approximativement transversalement à celui-ci, lequel mât est muni d'un organe récepteur ouvert vers le haut et présentant au moins une paroi approximativement verticale écartée radialement dudit mât et lequel élément est muni, à son extrémité devant être assemblée au mât, d'un organe de serrage solidaire de l'élément et apte à chevaucher ladite paroi de l'organe récepteur, ledit organe de serrage possédant une première surface de serrage coopérant avec la surface intérieure de la paroi et une seconde surface située à l'extérieur de la paroi et écartée de celle-ci, au moins une fente approximativement verticale traversant ledit organe de serrage et débouchant entre les première et seconde surfaces précitées, et est muni également d'un organe de verrouillage mobile dans la susdite fente pour être engagé entre la surface extérieure de la paroi de l'organe récepteur et ladite seconde surface de l'organe de serrage.The present invention relates to improvements made to the securing arrangements for, in a scaffolding, to assemble to a mast at least one element, such as a cross member or the like, extending approximately transversely thereto, which mast is provided with a receiving member open upwards and having at least one approximately vertical wall spaced radially from said mast and which element is provided, at its end to be assembled with the mast, of a clamping member integral with the element and capable of overlapping said wall of the receiving member, said clamping member having a first clamping surface cooperating with the inner surface of the wall and a second surface located outside the wall and spaced from the latter, at least one approximately vertical slot passing through said clamping member and emerging between the first and second surfaces mentioned above, and is also provided with a member movable locking in said slot to be engaged between the outer surface of the wall of the receiving member and said second surface of the clamping member.

L'invention concerne en outre des perfectionnements apportés aux organes de serrage utilisable dans un agencement de solidarisation tel que défini ci-dessus, ainsi que des perfectionnements apportés aux ensembles constitués d'un tel organe de serrage et d'un organe de verrouillage.The invention further relates to improvements made to the clamping members usable in a securing arrangement as defined above, as well as improvements made to the assemblies consisting of such a clamping member and a locking member.

L'invention s'applique essentiellement, bien que de façon non exclusive, aux échafaudages et aux pièces, notamment aux mâts et aux traverses ou autres pièces analogues, permettant de constituer un échafaudage.The invention applies essentially, although not exclusively, to scaffolding and parts, in particular masts and sleepers or other similar parts, making it possible to constitute a scaffolding.

On connaît divers agencements de solidarisation du type défini plus haut qui tous présentent l'inconvénient important de ne pas offrir une solidarisation sûre de la traverse ou analogue au mât.Various securing arrangements of the type defined above are known, all of which have the significant drawback of not offering secure securing of the cross member or the like to the mast.

Dans certains agencements connus, la paroi solidaire du mât sur laquelle s'effectue le serrage de l'extrémité de la traverse ou analogue possède des faces mutuellement parallèles. Le serrage de l'organe de serrage sur cette paroi n'est alors fonction que de l'importance du frottement intervenant entre les surfaces coopérantes ; de ce fait, si l'organe de serrage (ou la traverse) est soumis à un effort de soulèvement suffisamment élevé (choc accidentel par exemple) et supérieur à la force de serrage tributaire des frottements, l'organe de serrage peut être intempestivement dégagé de l'organe récepteur.In certain known arrangements, the wall integral with the mast on which the end of the cross member or the like is clamped has mutually parallel faces. The clamping of the clamping member on this wall is then only a function of the amount of friction occurring between the cooperating surfaces; therefore, if the clamping member (or the cross member) is subjected to a sufficiently high lifting force (accidental shock for example) and greater than the clamping force dependent on friction, the clamping member may be inadvertently released of the receiving organ.

Dans d'autres agencements connus, pour pallier l'inconvénient qui vient d'être énoncé, les faces de la paroi de l'organe récepteur ne sont pas parallèles et divergent l'une de l'autre vers le haut. Toutefois, la structure adoptée pour la paroi fait que soit elle peut se déformer sous l'action d'un effort important et, retrouvant alors une configuration à faces approximativement parallèles, elle ne peut pas retenir efficacement la traverse, soit elle ne peut pas s'opposer à un ébranlement de la liaison s'accompagnant d'un déblocage des pièces qui peut s'avérer dangereux.In other known arrangements, to overcome the drawback which has just been stated, the faces of the wall of the receiving member are not parallel and diverge from one another upwards. However, the structure adopted for the wall means that either it can deform under the action of a significant force and, then finding a configuration with approximately parallel faces, it cannot effectively retain the crosspiece, or it cannot s '' oppose a shaking of the link accompanied by an unlocking of the parts which can be dangerous.

On connaît aussi d'autres agencements qui s'avèrent plus sûrs que ceux dont les inconvénients sont exposés plus haut, mais qui à cette fin présentent un nombre plus élevé de pièces composantes, ce qui rend plus complexes et plus longues les opérations de montage et de démontage.Other arrangements are also known which prove to be safer than those whose drawbacks are explained above, but which for this purpose have a higher number of component parts, which makes the assembly operations more complex and longer. disassembly.

Enfin, quelle que soit la structure des agencements de solidarisation connus, ils présentent tous l'inconvénient qu'une traverse complète ne peut pas être montée ou démontée par une personne seule et que deux personnes doivent être présentes simultanément pour travailler conjointement respectivement aux deux extrémités de la traverse.Finally, whatever the structure of the known fastening arrangements, they all have the drawback that a complete sleeper cannot be assembled or disassembled by a single person and that two people must be present simultaneously to work jointly at the two ends respectively. of the sleeper.

L'invention a essentiellement pour but de remédier, dans toute la mesure du possible, aux divers inconvénients des agencements actuels et de proposer un agencement perfectionné qui donne mieux satisfaction aux diverses exigences de la pratique, tout en faisant en sorte qu'il n'en résulte ni complication supplémentaire ni élévation des coûts à la fabrication, à l'utilisation et à l'entretien.The object of the invention is essentially to remedy, as far as possible, the various drawbacks of current arrangements and to propose an improved arrangement which better meets the various requirements of practice, while ensuring that it does not This results in no additional complications or higher costs for manufacturing, use and maintenance.

A ces fins, un agencement de solidarisation permettant, dans un échafaudage, d'assembler à un mât au moins un élement tel qu'une traverse ou analogue, ainsi que défini plus haut, se caractérise essentiellement, étant agencé conformément à l'invention, par la combinaison des dispositions qui suivent :

  • - la paroi de l'organe récepteur est verticalement incurvée en arc de cercle à concavité tournée vers le mât et s'écartant du mât du bas vers le haut,
  • - la première surface de serrage de l'organe de serrage est incurvée en arc de cercle avec une configuration complémentaire de celle de la surface intérieure de la paroi de l'organe récepteur,
  • - la surface extérieure de la paroi de l'organe est incurvée en arc de cercle à concavité tournée vers le mât, et
  • - l'organe de verrouillage présente une forme générale incurvée avec deux surfaces mutuellement parallèles incurvées en arc en cercle et aptes à coopérer étroitement et sans jeu respectivement avec la surface incurvée extérieure de la paroi de l'organe récepteur et la seconde surface de l'organe de serrage lorsque ledit organe de verrouillage est en position de verrouillage, ledit organe de verrouillage et ledit organe récepteur étant mutuellement agencés de manière que soit empêché tout mouvement de l'organe de serrage monté et verrouillé sur l'organe récepteur, notamment de pivotement autour du mât ou de rotation autour de l'axe de l'élément.
For these purposes, a fastening arrangement allowing, in a scaffolding, to assemble to a mast at least one element such as a cross-member or the like, as defined above, is essentially characterized, being arranged in accordance with the invention, by the combination of the following provisions:
  • the wall of the receiving member is vertically curved in an arc of a concavity turned towards the mast and deviating from the mast from the bottom upwards,
  • the first clamping surface of the clamping member is curved in an arc of a circle with a configuration complementary to that of the inner surface of the wall of the receiving member,
  • the external surface of the wall of the member is curved in an arc of a circle with a concavity facing the mast, and
  • - The locking member has a generally curved shape with two mutually parallel surfaces curved in a circular arc and capable of cooperating closely and without play respectively with the curved outer surface of the wall of the receiving member and the second surface of the clamping member when said locking member is in the locking position, said locking member and said receiving member being mutually arranged so that any movement of the clamping member mounted and locked on the receiving member, in particular pivoting, is prevented around the mast or rotating around the axis of the element.

Grâce à cette configuration, la retenue de l'organe de serrage sur l'organe récepteur - et donc la solidarisation de l'élément tel que traverse ou analogue au mât - n'est plus tributaire de la seule force de serrage exercée sur la paroi de l'organe récepteur, mais est due essentiellement à la géométrie curviligne de l'ensemble des pièces coopérantes qui fait que, une fois l'organe de verrouillage en position dans l'organe de serrage contre la face externe de la paroi de l'organe récepteur, il est impossible que l'organe de serrage puisse se dégager intempestivement de l'organe récepteur. Même si l'organe de verrouillage n'est pas complètement enfoncé dans l'organe de serrage en position de verrouillage, il est possible de faire en sorte que les formes curvilignes dudit organe de verrouillage et de la face externe de la paroi de l'organe récepteur rendent impossible une désolida- risation intempestive et constituent une sécurité efficace que ne présente aucun des dispositifs de même fonction connus à ce jour.Thanks to this configuration, the retention of the clamping member on the receiving member - and therefore the joining of the element such as cross or ana mast mast - no longer dependent on the only clamping force exerted on the wall of the receiving member, but is mainly due to the curvilinear geometry of all of the cooperating parts which means that once the locking in position in the clamping member against the external face of the wall of the receiving member, it is impossible for the clamping member to be able to disengage inadvertently from the receiving member. Even if the locking member is not fully inserted into the clamping member in the locking position, it is possible to ensure that the curvilinear shapes of said locking member and of the external face of the wall of the receiving member makes inadvertent uncoupling impossible and constitutes effective security which none of the devices of the same function known to date has.

En outre, du fait même que l'assemblage et le verrouillage de l'organe de serrage sur l'organe récepteur résultent de la seule forme curviligne des faces coopérantes et qu'il n'est plus besoin qu'un effort de serrage notable soit exercé sur la paroi de l'organe récepteur par les organes qui la chevauchent (organe de serrage et organe de verrouillage), l'organe de verrouillage peut être simplement introduit sans jeu, mais aussi sans emmanchement à force entre la surface extérieure de la paroi de l'organe récepteur et la seconde surface de l'organe de serrage qui sont mutuellement parallèles.In addition, the very fact that the assembly and locking of the clamping member on the receiving member result from the only curvilinear shape of the cooperating faces and that there is no longer any need for a significant clamping force to be exerted on the wall of the receiving member by the overlapping members (clamping member and locking member), the locking member can be simply inserted without play, but also without force fitting between the outer surface of the wall of the receiving member and the second surface of the clamping member which are mutually parallel.

Différents modes de réalisation peuvent être envisagés pour la seconde surface de l'organe de serrage : notamment elle peut, elle aussi, être incurvée en arc de cercle à concavité tournée vers le mât et être sensiblement parallèle à la surface extérieure de la paroi de l'organe récepteur ; ou bien encore être sensiblement plane et tangente à une surface sensiblement parallèle à la surface extérieure de la paroi de l'organe récepteur; ou bien encore être constituée sous forme d'un élément en forme de tige.Different embodiments can be envisaged for the second surface of the clamping member: in particular, it too can be curved in an arc of a concavity turned towards the mast and be substantially parallel to the exterior surface of the wall of the 'receiving organ; or else be substantially planar and tangent to a surface substantially parallel to the exterior surface of the wall of the receiving member; or even be constituted in the form of a rod-shaped element.

De préférence, dans l'un ou l'autre des deux premiers modes de réalisation précités, la seconde surface de l'organe de serrage et la surface coopérant de l'organe de verrouillage présentent respectivement deux premiers épaulements disposés de manière telle que, l'organe de verrouillage étant en position de verrouillage, l'épaulement de l'organe de verrouillage soit en appui contre l'épaulement de l'organe de serrage et que l'organe de verrouillage soit retenu gravitairement sur l'organe de serrage. Cette disposition a essentiellement pour avantage de définir la position occupée par l'organe de verrouillage lorsqu'il est dans la position verrouillée.Preferably, in one or other of the first two embodiments mentioned above, the second surface of the clamping member and the cooperating surface of the locking member respectively have two first shoulders arranged in such a way that, l 'locking member being in the locking position, the shoulder of the locking member is in abutment against the shoulder of the clamping member and that the locking member is retained by gravity on the clamping member. This arrangement essentially has the advantage of defining the position occupied by the locking member when it is in the locked position.

De même, il est alors avantageux que la seconde surface de l'organe de serrage et la surface coopérante de l'organe de verrouillage présentent respectivement deux seconds épaulements disposés de manière telle que, lorsqu'ils coopèrent, l'organe de verrouillage soit librement engagé dans la fente mais non enfoncé en position de verrouillage tout en empêchant le dégagement de l'organe de serrage hors de l'organe récepteur. On définit ainsi une position intermédiaire pour laquelle, bien que l'organe de verrouillage ne soit pas encore dans sa position verrouillage, ledit organe de verrouillage empêche toutefois l'organe de serrage de se dégager de l'organe récepteur. Il s'agit d'une position d'attente qui confère un certain degré de liberté entre le mât et l'élément (traverse ou analogue) utile par exemple au cours des opérations de montage ou de démontage.Likewise, it is then advantageous for the second surface of the clamping member and the cooperating surface of the locking member respectively to have two second shoulders arranged in such a way that, when they cooperate, the locking member is freely engaged in the slot but not pressed in the locking position while preventing the clamping member from being released from the receiving member. An intermediate position is thus defined for which, although the locking member is not yet in its locking position, said locking member however prevents the clamping member from disengaging from the receiving member. It is a waiting position which gives a certain degree of freedom between the mast and the element (cross member or the like) useful for example during assembly or disassembly operations.

En outre, il est également avantageux alors que l'extrémité inférieure de l'organe de verrouillage soit agencée pour coopérer avec le premier épaulement de l'organe de serrage, l'organe de verrouillage étant alors dégagé hors de la fente au moins d'une manière suffisante pour libérer l'organe de serrage vis-à-vis de l'organe récepteur et autoriser leur dégagement ou leur engagement mutuel. L'organe de verrouillage est alors dans une position telle qu'il est encore ou déjà en place dans l'assemblage, mais qu'il ne solidarise pas l'organe de serrage à l'organe récepteur : l'organe de serrage peut facilement être mis en place sur l'organe récepteur ou en être dégagé sans aucune difficulté. On remarquera ici que cette possibilité de positionnement "en attente" de l'organe de verrouillage permet à une seule personne de travailler successivement sur les deux extrémités d'une traverse et, donc, de procéder, à elle seule, au montage et au démontage de la traverse ou analogue.In addition, it is also advantageous while the lower end of the locking member is arranged to cooperate with the first shoulder of the clamping member, the locking member then being released from the slot at least sufficient to release the clamping member vis-à-vis the receiving member and allow their release or mutual engagement. The locking member is then in a position such that it is still or already in place in the assembly, but that it does not secure the clamping member to the receiving member: the clamping member can easily be placed on the receiving member or be released from it without any difficulty. It will be noted here that this possibility of "waiting" positioning of the locking member allows a single person to work successively on the two ends of a cross member and, therefore, to proceed, on its own, to assembly and disassembly of the cross member or the like.

Dans le cas du troisième mode de réalisation précité, il peut être envisagé que la surface de l'organe de verrouillage coopérant avec la seconde surface d'appui présente un épaulement disposé de manière telle que, l'organe de verrouillage étant en position de verrouillage, l'épaulement de l'organe de verrouillage soit en appui contre la seconde surface d'appui en forme de tige et que l'organe de verrouillage soit retenu gravitairement sur l'organe de serrage. On peut alors avantageusement prévoir en outre que l'extrémité inférieure de l'organe de verrouillage soit agencé pour coopérer avec la seconde surface d'appui, l'organe de verrouillage étant alors dégagé hors de la fente au moins d'une manière suffisante pour libérer l'organe de serrage vis-à-vis de l'organe récepteur et autoriser leur dégagement.In the case of the aforementioned third embodiment, it can be envisaged that the surface of the locking member cooperating with the second bearing surface has a shoulder arranged in such a way that, the locking member being in the locking position , the shoulder of the locking member is in abutment against the second rod-shaped bearing surface and that the locking member is retained by gravity on the clamping member. It can then advantageously be further provided that the lower end of the locking member is arranged to cooperate with the second bearing surface, the locking member then being released from the slot at least in a manner sufficient to release the clamping member vis-à-vis the receiving member and authorize their release.

En particulier, on notera ici que le montage de la traverse sur l'organe récepteur s'effectue, grâce aux dispositions adoptées conformément à l'invention, de façon automatique, sans requérir une manipulation de pièces. Ainsi, l'organe de serrage équipant l'extrémité de la traverse est présenté devant l'organe récepteur en forme de coupelle ; l'organe de verrouillage, qui en pratique reste à demeure dans la fente de l'organe de serrage, est alors tombé au fond de la fente sous l'action de la gravité. L'organe de serrage est ensuite posé sur la coupelle, dont le bord repousse l'organe de verrouillage vers le haut en même temps que l'organe de serrage s'emboîte par simple gravité sur la coupelle. Une fois l'organe de serrage en position à l'intérieur de la coupelle, l'organe de verrouillage retombe par simple gravité dans la fente, jusqu'en position de semi-verrouillage (les deux seconds épaulements précités étant en coopération mutuelle) ou de verrouillage (troisième mode de réalisation).In particular, it will be noted here that the mounting of the cross member on the receiving member is carried out, thanks to the arrangements adopted in accordance with the invention, automatically, without requiring manipulation of parts. Thus, the clamping member fitted to the end of the cross member is presented in front of the receiving member in the form of a cup; the locking member, which in practice remains permanently in the slot of the clamping member, then fell to the bottom of the slot under the action of gravity. The clamping member is then placed on the cup, the edge of which pushes the locking member upwards in at the same time that the clamping member fits by simple gravity on the cup. Once the clamping member in position inside the cup, the locking member falls by simple gravity into the slot, until the semi-locking position (the two aforementioned second shoulders being in mutual cooperation) or lock (third embodiment).

Pour retenir l'organe de verrouillage dans l'organe de serrage de façon à le rendre "imperdable", on peut prévoir que l'extrémité inférieure de l'organe de verrouillage possède une saillie transversale saillant latéralement et en ce que au moins une face intérieure latérale de la fente possède un évidement de réception de ladite saillie positionnée de manière telle que, lorsque le doigt est reçu dans l'évidement, l'organe de verrouillage soit dans une position partiellement dégagée pour laquelle l'organe de serrage peut être dégagé de l'organe récepteur ou engagé sur celui-ci.To retain the locking member in the clamping member so as to make it "captive", provision may be made for the lower end of the locking member to have a transverse projection projecting laterally and in that at least one face inner side of the slot has a recess for receiving said projection positioned so that, when the finger is received in the recess, the locking member is in a partially released position for which the clamping member can be released of the receiving organ or engaged thereon.

Dans un exemple de réalisation d'exécution facile, l'organe récepteur est une coupelle ayant approximativement la forme générale d'une zone sphérique ouverte vers le haut.In an example of an easy execution, the receiving member is a cup having approximately the general shape of a spherical zone open upwards.

Pour empêcher, comme indiqué plus haut, tout mouvement de l'organe de serrage monté et verrouillé sur l'organe récepteur, notamment de pivotement autour du mât ou bien de rotation de l'élément sur lui-même, autour de son axe, on peut prévoir que la paroi de l'organe récepteur possède une face intérieure sensiblement en forme de zone sphérique et une face extérieure à contour polygonal, notamment octogonal, cette face extérieure étant constituée de facettes incurvées sensiblement en forme de trapèzes isocèles curvilignes. A titre de variante, il est également possible de prévoir que la paroi de l'organe récepteur possède des faces intérieure et extérieure mutuellement sensiblement parallèles et sensiblement en forme de zones sphériques concentriques et que ladite face extérieure soit munie d'au moins une gorge sensiblement verticale dans laquelle est engagé le bord correspondant de l'organe de verrouillage ; dans ce cas, avantageusement la face extérieure de la paroi de l'organe récepteur est munie de plusieurs gorges, notamment quatre ou huit, régulièrement espacées sur le pourtour de ladite face, ces rainures matérialisant autant de position de montage d'éléments, tels que des traverses ou analogues, sur l'organe récepteur.To prevent, as indicated above, any movement of the clamping member mounted and locked on the receiving member, in particular of pivoting around the mast or else of rotation of the element on itself, around its axis, may provide that the wall of the receiving member has an inner face substantially in the form of a spherical zone and an outer face with a polygonal contour, in particular octagonal, this outer face being made up of curved facets substantially in the form of curvilinear isosceles trapezoids. As a variant, it is also possible to provide that the wall of the receiving member has mutually substantially parallel inner and outer faces and substantially in the form of concentric spherical zones and that said outer face is provided with at least one substantially groove. vertical in which is engaged the corresponding edge of the locking member; in this case, advantageously the outer face of the wall of the receiving member is provided with several grooves, in particular four or eight, regularly spaced around the periphery of said face, these grooves materializing as many mounting positions of elements, such as sleepers or the like on the receiving member.

Pour améliorer le positionnement mutuel des organes coopérants et leur retenue en position assemblée et verrouillée, on prévoit que, à l'opposé de la première surface de serrage précitée, l'organe de serrage présente une portée extérieure apte à être en appui contre le mât.To improve the mutual positioning of the cooperating members and their retention in the assembled and locked position, it is provided that, opposite the aforementioned first clamping surface, the clamping member has an external bearing capable of being pressed against the mast .

Il est également possible de prévoir que, lorsqu'il est en position de verrouillage, l'organe de verrouillage est effacé dans la fente et ne dépasse pas la face supérieure de l'organe de serrage ; ainsi on dégage toute la partie supérieure de la traverse comprise entre les deux mâts réunis par cette traverse, par exemple pour la mise en place d'un platelage.It is also possible to provide that, when it is in the locking position, the locking member is obliterated in the slot and does not exceed the upper face of the clamping member; thus the entire upper part of the crosspiece between the two masts joined by this crossbar is released, for example for the installation of a deck.

Un autre aspect de l'invention consiste également à proposer un organe de serrage pour l'extrémité d'un élément d'échafaudage, tel qu'une traverse ou analogue, destiné à être assemblé à un mât dans une position approximativement transversale à celui-ci, organe de serrage qui, étant agencé conformément à l'invention, se carartérise essentiellement en ce qu'il comporte une première surface de serrage incurvée en arc de cercle, pour coopérer avec une surface intérieure d'une paroi d'un organe récepteur solidaire du mât, et une seconde surface écartée de la première surface de serrage, une fente traversant ledit organe de serrage pour recevoir un organe de verrouillage et débouchant entre ses première et seconde surfaces précitées.Another aspect of the invention also consists in providing a clamping member for the end of a scaffolding element, such as a cross-member or the like, intended to be assembled to a mast in a position approximately transverse thereto. ci, clamping member which, being arranged in accordance with the invention, is essentially cararterized in that it comprises a first clamping surface curved in an arc of a circle, to cooperate with an inner surface of a wall of a receiving member integral with the mast, and a second surface spaced from the first clamping surface, a slot passing through said clamping member to receive a locking member and opening out between its first and second surfaces mentioned above.

Encore un autre aspect de l'invention consiste à proposer un ensemble constitué d'un organe de serrage et d'un organe de verrouillage qui, étant agencé selon l'invention, se caractérise essentiellement en ce que l'organe de serrage est agencé comme il vient d'être indiqué et en ce que l'organe de verrouillage est engagé de façon mobile dans la fente de l'organe de serrage et présente une forme générale incurvée avec deux surfaces mutuellement opposées parallèles incurvées en arc de cercle et concentriques à la surface incurvée en arc de cercle de l'organe de serrage lorsqu'il est en position de verrouillage dans celui-ci.Yet another aspect of the invention consists in proposing an assembly consisting of a clamping member and a locking member which, being arranged according to the invention, is essentially characterized in that the clamping member is arranged as it has just been indicated and in that the locking member is movably engaged in the slot of the clamping member and has a generally curved shape with two mutually opposite parallel surfaces curved in an arc of a circle and concentric with the curved surface in an arc of the clamping member when it is in the locking position therein.

Encore un autre aspect de l'invention consiste à proposer un mât d'échafaudage destiné à supporter un élément d'échafaudage tel qu'une traverse ou analogue, ledit mât étant pourvu d'un organe récepteur en forme de coupelle à configuration générale en zone sphérique, ouverte vers le haut, pour recevoir un organe de serrage solidaire de l'extrémité dudit élément et constitué comme indiqué ci-dessus, mât d'échafaudage qui, étant agencé selon l'invention, se caractérise essentiellement en ce que l'organe récepteur en forme générale de coupelle présente une face intérieure sensiblement en forme de zone sphérique et une face extérieure possédant un contour polygonal, notamment octogonal, cette face extérieure étant constituée de facettes incurvées sensiblement en forme de trapèzes isocèles curvilignes ; ou bien, à titre de variante, qui se caractérise essentiellement en ce que l'organe récepteur en forme générale de coupelle présente des faces intérieure et extérieure mutuellement sensiblement parallèles et sensiblement en forme de zones sphériques concentriques et en ce que ladite face extérieure est munie d'au moins une gorge, notamment de quatre ou huit gorges régulièrement espacées sur le pourtour de ladite face, sensiblement verticale dans laquelle est engagé le bord correspondant de l'organe de verrouillage.Yet another aspect of the invention consists in providing a scaffolding mast intended to support a scaffolding element such as a cross member or the like, said mast being provided with a receiving member in the form of a cup with general configuration in the zone spherical, open upwards, to receive a clamping member integral with the end of said element and constituted as indicated above, a scaffolding mast which, being arranged according to the invention, is essentially characterized in that the member receiver in the general form of a cup has an inner face substantially in the form of a spherical zone and an outer face having a polygonal contour, in particular an octagonal one, this outer face being made up of curved facets substantially in the form of curvilinear isosceles trapezoids; or alternatively, which is essentially characterized in that the generally cup-shaped receiving member has mutually substantially parallel inner and outer faces and substantially in the form of concentric spherical zones and in that said outer face is provided at least one groove, in particular four or eight grooves regularly spaced around the periphery of said face, substantially vertical in which is engaged the corresponding edge of the locking member.

En se référant tout d'abord essentiellement aux figures 1, 2, 5 et 6, un mât d'échafaudage 1 est muni d'un organe récepteur 2 en forme de coupelle ouverte vers le haut, qui lui est solidarisée de toute façon connue (soudure par exemple). Cette coupelle 2 possède la forme générale approximative d'une zone sphérique, sa paroi 3 étant, en section verticale, incurvée en arc de cercle avec une concavité tournée vers le mât en s'éloignant du mât du bas vers le haut. La base de la coupelle 3 peut être percée d'un ou plusieurs orifices 6 pour l'évacuation des eaux.Referring first of all essentially to FIGS. 1, 2, 5 and 6, a scaffolding mast 1 is provided with a receiving member 2 in the form of a cup open upwards, which is secured to it in any known way ( welding for example). This cup 2 has the approximate general shape of a spherical zone, its wall 3 being, in vertical section, curved in an arc of a circle with a concavity turned towards the mast away from the mast from the bottom up. The base of the cup 3 can be pierced with one or more orifices 6 for the evacuation of water.

Dans l'exemple représenté aux figures 1 à 4, et comme on le voit le mieux à la figure 2, la paroi 3 possède une face intérieure 4 qui est sensiblement en forme de zone sphérique et une face extérieure 5 qui, en vue de dessus, forme un contour polygonal ; en pratique ce contour polygonal possède un nombre pair de côté, de façon courante soit quatre, soit huit côtés (octogone) comme représenté. Autrement dit cette face extérieure 5 est constituée de facettes incurvées 7 sensiblement en forme de trapèze isocèle curviligne. Le mât 1 équipé d'une coupelle 2 de cette configuration est représenté en perspective à la figure 7.In the example shown in Figures 1 to 4, and as best seen in Figure 2, the wall 3 has an inner face 4 which is substantially in the form of a spherical zone and an outer face 5 which, in top view , forms a polygonal outline; in practice, this polygonal contour has an even number of sides, commonly either four or eight sides (octagon) as shown. In other words, this outer face 5 consists of curved facets 7 substantially in the shape of a curvilinear isosceles trapezoid. The mast 1 fitted with a cup 2 of this configuration is shown in perspective in FIG. 7.

A l'extrémité d'un élément d'échafaudage 8, tel qu'une traverse ou analogue, est disposé (soit faisant corps avec la traverse, ou bien solidarisé à celle-ci - par soudage ou vissage par exemple -) un organe de serrage 9 qui est représenté en position d'assemblage à la figure 1 et de façon isolée à la figure 5.At the end of a scaffolding element 8, such as a cross-member or the like, is arranged (either integral with the cross-member, or else joined thereto - by welding or screwing for example -) a clamp 9 which is shown in the assembly position in FIG. 1 and in isolation in FIG. 5.

Vers l'avant, l'organe de serrage 9 comporte, inférieurement, une surface de serrage 10 incurvée en arc de cercle de même courbure que la face intérieure 4 de la paroi 3 de l'organe récepteur 2 afin de coopérer avec cette dernière. Autrement dit, la partie avant 11 de l'organe de serrage 9 constitue un bec d'accrochage qui est apte à s'emboîter dans l'organe récepteur et à prendre appui sur celui-ci.Towards the front, the clamping member 9 comprises, below, a clamping surface 10 curved in an arc of a circle of the same curvature as the inner face 4 of the wall 3 of the receiving member 2 in order to cooperate with the latter. In other words, the front part 11 of the clamping member 9 constitutes a latching spout which is able to fit into the receiving member and to bear on it.

En arrière de la surface de serrage 10, l'organe de serrage 9 est taversé par une fente verticale 12 qui, dans sa partie supérieure, s'évase en direction de l'avant (paroi inclinée vers l'avant 13) et qui, dans sa partie inférieure, est délimitée par la surface de serrage 10 vers l'avant et, vers l'arrière, par une seconde surface 14 distante de la précédente, qui est destinée à servir d'appui et de guidage à un organe de verrouillage dont question ci-après. Cette seconde surface peut présenter toute forme compatible avec sa fonction d'appui et de guidage de l'organe de verrouillage et telle qu'elle n'entrave pas le libre mouvement de celui-ci. Dans l'exemple représenté à la figure 1, cette seconde surface 14 est, elle aussi, incurvée en arc de cercle et est parallèle et concentrique à la surface 10. Autrement dit, dans la position de montage représentée à la figure 1, cette seconde surface 14 est sensiblement parallèle et concentrique à la face extérieure 5 de la paroi 3 de l'organe récepteur.Behind the clamping surface 10, the clamping member 9 is taversed by a vertical slot 12 which, in its upper part, widens in the direction of the front (wall inclined towards the front 13) and which, in its lower part, is delimited by the clamping surface 10 towards the front and, towards the rear, by a second surface 14 distant from the previous one, which is intended to serve as support and guide for a locking member of which question below. This second surface can have any shape compatible with its support and guiding function of the locking member and such that it does not hamper the free movement of the latter. In the example shown in FIG. 1, this second surface 14 is also curved in an arc of a circle and is parallel and concentric with the surface 10. In other words, in the mounting position shown in FIG. 1, this second surface 14 is substantially parallel and concentric with the outer face 5 of the wall 3 of the receiving member.

Dans la fente 12 est logé un organe de verrouillage 15 de forme générale incurvée, qui présente deux surfaces opposées 16 et 17 mutuellement parallèles et incurvées en arc de cercle avec une configuration complémentaire de celles respectives de la face extérieure 5 de la paroi 3 de l'organe récepteur 2 et de la seconde surface 14 de l'organe de serrage 9. Le positionnement de l'organe de verrouillage 15 en position verrouillée à l'intérieur de l'organe de serrage 9, entre les faces 5 et 14 précitées, s'effectue sans jeu, mais aussi de façon libre et sans effort notable.In the slot 12 is housed a locking member 15 of generally curved shape, which has two opposite surfaces 16 and 17 mutually parallel and curved in an arc of a circle with a configuration complementary to those respective of the outer face 5 of the wall 3 of the the receiving member 2 and the second surface 14 of the clamping member 9. The positioning of the locking member 15 in the locked position inside the clamping member 9, between the aforementioned faces 5 and 14, takes place without play, but also freely and without significant effort.

Dans la position d'assemblage verrouillée représentée à la figure 1, tout effort exercé sur l'organe de serrage 9 (ou la traverse 8) en direction du haut, de même que tout effort de rotation exercé sur l'organe de serrage 9 ou la traverse 8 tendant à faire tourner cette dernière sur elle-même autour de son axe ou bien autour du mât 1 ne peuvent en aucun cas provoquer le dégagement de l'organe de serrage 9 hors de l'organe récepteur 2 : cet agencement procure un assemblage fiable, alors que par ailleurs les éléments constitutifs mis en jeu sont de fabrication et de coût sensiblement identiques à ceux des dispositifs antérieurs qui n'offraient pas le même degré de fiabilité.In the locked assembly position shown in FIG. 1, any force exerted on the clamping member 9 (or the cross member 8) in the upward direction, as well as any rotational force exerted on the clamping member 9 or the cross member 8 tending to rotate the latter on itself about its axis or else around the mast 1 can in no case cause the release of the clamping member 9 from the receiving member 2: this arrangement provides a reliable assembly, while moreover the constituent elements involved are of manufacture and cost substantially identical to those of the prior devices which did not offer the same degree of reliability.

La seconde surface 14 de l'organe de serrage 9 et la surface correspondante 17 de l'organe de verrouillage 15 présentent respectivement, dans leurs parties supérieures, deux épaulements 18 et 19 qui sont aptes à coopérer l'un avec l'autre lorsque l'organe de verrouillage est en position de verrouillage (figure 1) afin qu'il soit retenu dans une position définie. On notera que l'organe de verrouillage est agencé, dans sa partie supérieure, pour être alors entièrement effacé dans la fente 12 et dégager entièrement la partie supérieure de l'organe de serrage 9. On libère ainsi la totalité de la distance entre les deux mâts réunis par la traverse 8, ce qui facilite par exemple la mise en place d'un platelage.The second surface 14 of the clamping member 9 and the corresponding surface 17 of the clamping member locking 15 have respectively, in their upper parts, two shoulders 18 and 19 which are able to cooperate with each other when the locking member is in the locking position (Figure 1) so that it is retained in a defined position. It will be noted that the locking member is arranged, in its upper part, so as to then be entirely erased in the slot 12 and completely release the upper part of the clamping member 9. This thus frees the entire distance between the two masts joined by the crosspiece 8, which facilitates for example the establishment of a deck.

En outre, les mêmes surfaces 14 et 17 présentent deux autres épaulements 20 et 21 qui sont situés en un emplacement intermédiaire et qui sont aptes à coopérer l'un avec l'autre (figure 3) pour que l'organe de verrouillage 15 soit retenu gravitairement par l'organe de serrage 9 dans une position intermédiaire d'engagement positif non verrouillé. Les emplacements de ces épaulements 20 et 21 sont tels et la configuration (notamment la longueur) de l'organe de verrouillage 12 est telle que, dans cette position où ledit organe 12 repose gravitairement de façon libre sur l'organe de serrage 9, le dégagement de l'organe de serrage 9 hors de l'organe récepteur 2 ne soit pas possible. Cette position est donc une position intermédiaire d'attente qui, en cours de montage ou de démontage, confère à la traverse 8 une relative liberté de mouvement angulaire par rapport au mât 1 sans cependant que son dégagement total soit possible.In addition, the same surfaces 14 and 17 have two other shoulders 20 and 21 which are located in an intermediate location and which are able to cooperate with each other (Figure 3) so that the locking member 15 is retained by gravity by the clamping member 9 in an intermediate position of positive unlocked engagement. The locations of these shoulders 20 and 21 are such and the configuration (in particular the length) of the locking member 12 is such that, in this position where said member 12 rests freely by gravity on the clamping member 9, the release of the clamping member 9 from the receiving member 2 is not possible. This position is therefore an intermediate waiting position which, during assembly or disassembly, gives the cross-member 8 relative freedom of angular movement relative to the mast 1 without, however, its total clearance being possible.

Enfin, à son extrémité inférieure, l'organe de verrouillage 15 présente un plat 22 qui est apte à reposer sur l'épaulement précité 18 de la surface 14 de l'organe de serrage lorsque l'organe de verrouillage est en position dégagée vers le haut (voir figure 4). L'organe de verrouillage étant alors dégagé hors du couloir formé par les surfaces 14 et 5 en regard, l'organe de serrage 9 peut être mis librement en place sur l'organe récepteur 2 ou ôté de celui-ci.Finally, at its lower end, the locking member 15 has a flat 22 which is capable of resting on the abovementioned shoulder 18 of the surface 14 of the clamping member when the locking member is in the released position towards the top (see Figure 4). The locking member then being released out of the corridor formed by the surfaces 14 and 5 facing each other, the clamping member 9 can be freely placed on the receiving member 2 or removed from it.

Pour rendre l'organe de verrouillage imperdable, et l'empêcher de sortir totalement hors de la fente 12, son extrémité inférieure est munie d'un doigt 23 saillant de part et d'autre apte à s'engager dans deux évidements 24 pratiqués respectivement dans les parois latérales de la fente 12 sensiblement au droit de l'épaulement 18 (voir figure 3).To make the locking member captive, and prevent it from fully emerging from the slot 12, its lower end is provided with a protruding finger 23 on either side capable of engaging in two recesses 24 made respectively in the side walls of the slot 12 substantially in line with the shoulder 18 (see Figure 3).

Pour assurer le positionnement et le blocage mutuel des éléments, on prévoit par ailleurs que l'organe de serrage 9 soit en appui contre le mât par une surface de portée extérieure 25 qui est disposée au dessus du bec d'accrochage 11, à l'extrémité supérieure de l'organe de serrage.To ensure the positioning and mutual blocking of the elements, provision is also made for the clamping member 9 to be pressed against the mast by an external bearing surface 25 which is disposed above the hooking spout 11, at the upper end of the clamping member.

Le montage d'une traverse équipée comme il vient d'être indiqué sur le mât s'effectue comme suit. L'organe de serrage 9 équipant l'extrémité de la traverse 8 est présenté devant la coupelle 2 ; l'organe de verrouillage 15 est alors tombé au fond de la fente sous l'action de la gravité. L'organe de serrage 9 est ensuite posé sur la coupelle 2 dont le bord repousse l'organe de verrouillage 15 vers le haut en même temps que le bec d'accrochage 11 s'emboîte par simple gravité à l'intérieur de la coupelle 2. Ensuite, l'organe de verrouillage 15 retombe par simple gravité dans la fente jusqu'en position d'attente ou de semi-verrouillage représentée à la figure 3.Bien que n'étant pas encore verrouillé, l'organe de serrage 9 ne peut plus se dégager de lui-même hors de la coupelle 2. A ce stade, les organes de serrage 9, de verrouillage 15 et récepteur 2 sont encore dans une position mutuelle où toutes les surfaces incurvées ne sont pas encore parfaitement parallèles et concentriques. De ce fait, la phase finale d'enfoncement de l'organe de verrouillage (qui implique un dégagement des épaulements 20 et 21) s'effectue au marteau, en tapant sur l'extrémité supérieure de l'organe de verrouillage, pour aboutir à l'état verrouillé représenté à la figure 1.The assembly of a cross member equipped as just indicated on the mast is carried out as follows. The clamping member 9 fitted to the end of the cross member 8 is presented in front of the cup 2; the locking member 15 then fell to the bottom of the slot under the action of gravity. The clamping member 9 is then placed on the cup 2, the edge of which pushes the locking member 15 upwards at the same time as the hooking spout 11 engages by simple gravity inside the cup 2 Then, the locking member 15 falls by simple gravity into the slot until the standby or semi-locking position shown in FIG. 3. Although not yet locked, the clamping member 9 does not can no longer disengage itself from the cup 2. At this stage, the clamping members 9, locking device 15 and receiver 2 are still in a mutual position where all the curved surfaces are not yet perfectly parallel and concentric. Therefore, the final phase of driving in the locking member (which involves releasing the shoulders 20 and 21) is carried out with a hammer, tapping on the upper end of the locking member, to result in the locked state shown in Figure 1.

Le démontage s'effectue, inversement, en tapant au marteau sur l'extrémité inférieure de l'organe de verrouillage 15, ce qui l'amène dans la position de la figure 2 d'où il peut aisément être remonté dans la position dégagée de la figure 3.The disassembly is carried out, conversely, by tapping with a hammer on the lower end of the locking member 15, which brings it into the position of FIG. 2 from which it can easily be reassembled in the released position of Figure 3.

A la figure 8 on a représenté en perspective une variante de réalisation de la coupelle 2 associée au mât 1 et, à la figure 9, on a représenté toutes les pièces assemblées sur cette coupelle, dans la position verrouillée.In Figure 8 there is shown in perspective an alternative embodiment of the cup 2 associated with the mast 1 and, in Figure 9, there is shown all the parts assembled on this cup, in the locked position.

Dans cette variante, la coupelle 2 possède deux faces intérieure 4 et extérieure 5 qui sont sensiblement mutuellement parallèles, en forme de zones sphériques sensiblement concentriques. Dans la face extérieure 5 est creusée au moins une gorge verticale 26 ; en pratique on prévoit quatre ou huit gorges 26 (comme représenté à la figure 8) qui sont régulièrement réparties sur le pourtour de la coupelle et qui matérialisent autant de positions de montage pur des éléments 8 tels que des traverses (de la même namière que les faces 7 de la configuration de la coupelle de la figure 7).In this variant, the cup 2 has two inner 4 and outer 5 faces which are substantially mutually parallel, in the form of substantially concentric spherical zones. In the outer face 5 is hollowed out at least one vertical groove 26; in practice four or eight grooves 26 are provided (as shown in FIG. 8) which are regularly distributed around the periphery of the cup and which materialize as many mounting positions for the elements 8 such as crosspieces (of the same name as the faces 7 of the configuration of the cup of FIG. 7).

Comme visible à la figure 9, le bord de l'organe de verrouillage auquel est associé la surface incurvée 16 est partiellement engagé à l'intérieur de la gorge 26.As can be seen in FIG. 9, the edge of the locking member with which the curved surface 16 is associated is partially engaged inside the groove 26.

Grâce à la butée transversale que constitue cette gorge 26 pour l'organe de verrouillage 15 dans ce dernier agencement, aussi bien que grâce aux variations d'épaisseur de la paroi 3 de la coupelle 2 dans l'engagement des figures 1 à 7, on empêche tout mouvement de l'organe de serrage 9 par rapport à l'organe récepteur 2 : l'assemblage obtenu est fiable en toutes circonstances.Thanks to the transverse stop that constitutes this groove 26 for the locking member 15 in this latter arrangement, as well as thanks to the variations in thickness of the wall 3 of the cup 2 in the engagement of FIGS. 1 to 7, we prevents any movement of the clamping member 9 relative to the receiving member 2: the assembly obtained is reliable in all circumstances.

Comme indiqué plus haut, la seconde surface 14 peut avoir toute forme compatible avec sa fonction. Elle peut donc non seulement être incurvée en arc de cercle et être parallèle et concentrique à la surface de serrage 10, mais elle peut aussi être sensiblement plane et être tangente à une surface incurvée en arc de cercle parallèle et concentrique à la surface de serrage 10, ou bien encore être constituée sous forme d'une simple tige ou d'un élément analogue. La figure 10 représente un tel mode de réalisation.As indicated above, the second surface 14 can have any shape compatible with its function. It can therefore not only be curved in an arc of a circle and be parallel and concentric with the clamping surface 10, but it can also be substantially planar and be tangent to a curved surface in an arc of parallel and concentric circle to the clamping surface 10, or alternatively be in the form of a simple rod or the like. FIG. 10 represents such an embodiment.

Sur la figure 10 (sur laquelle les mêmes références numériques ont été conservées pour désigner les organes identiques ou analogues à ceux des figures 1 à 6), l'organe de serrage 9 présente une fente 12 délimitée latéralement par deux flasques 27 dont la forme diffère sensiblement de celle des flasques du mode de réalisation représenté aux figures 1 à 6. Chaque flasque 27 présente verticalement une largeurdif- férente de part et d'autre d'un épaulement curviligne 28 : en haut, en raison d'une épaisseur plus importante, les parties supérieures 29 en regard définissent un étranglement tandis qu'en bas, en raison d'une épaisseur moindre, les parties inférieures en regard définissent une partie de fente plus large.In FIG. 10 (in which the same numerical references have been kept to designate the members identical or similar to those of FIGS. 1 to 6), the clamping member 9 has a slot 12 delimited laterally by two flanges 27 whose shape differs substantially that of the flanges of the embodiment shown in FIGS. 1 to 6. Each flange 27 has a different width vertically on either side of a curvilinear shoulder 28: at the top, due to a greater thickness, the upper facing portions 29 define a constriction while at the bottom, due to a smaller thickness, the lower facing portions define a wider slot portion.

A l'extrémité inférieure, une tige transversale 31 s'étend entre les deux flasques en regard de la partie avant 11 de l'organe d'accrochage. La partie de sa surface tournée vers ladite partie avant 11 constitue la susdite seconde surface 14 d'appui et de guidage de l'organe de verrouillage 15.At the lower end, a transverse rod 31 extends between the two flanges facing the front part 11 of the attachment member. The part of its surface facing said front part 11 constitutes the aforesaid second surface 14 for supporting and guiding the locking member 15.

L'organe de verrouillage 15 (qui est ici représenté muni d'un évidement 32 dans sa partie supérieure en vue de son allègement) présente approximativement la même forme générale que celui du mode de réalisation des figures 1 à 6, à ceci près que son bord destiné à coopérer avec la tige 31 est conformée de manière à constituer un talon d'appui 33 définissant la surface 17 précitée qui, ici, est curviligne et épouse la forme du contour de la tige 31 sur laquelle s'appuie l'organe 15 en position de verrouillage montrée à la figure 10.The locking member 15 (which is shown here provided with a recess 32 in its upper part for its lightening) has approximately the same general shape as that of the embodiment of Figures 1 to 6, except that its edge intended to cooperate with the rod 31 is shaped so as to constitute a bearing heel 33 defining the aforementioned surface 17 which, here, is curvilinear and conforms to the shape of the contour of the rod 31 on which the member 15 rests in the locking position shown in Figure 10.

La partie de l'organe de verrouillage 15 qui borde la surface 17 présente en outre une surépaisseur 23 jouant le même rôle que le doigt 23 précité et qui vient buter contre l'épaulement 28 lorsque l'organe de verrouillage 15 est soulevé, afin d'éviter que celui-ci sorte de la fente.The part of the locking member 15 which borders the surface 17 also has an extra thickness 23 playing the same role as the aforementioned finger 23 and which abuts against the shoulder 28 when the locking member 15 is raised, in order to '' prevent it from coming out of the slot.

Enfin, l'extrémité inférieure 22 de l'organe de verrouillage 15 est conformée pour reposer sur la tige 31 quand l'organe de verrouillage 15 est soulevé et pour le retenir dans sa position dégagée vers le haut (correspondant à celle montrée à la figure 4).Finally, the lower end 22 of the locking member 15 is shaped to rest on the rod 31 when the locking member 15 is raised and to retain it in its upwardly released position (corresponding to that shown in FIG. 4).

On poura également noter que, dans les modes de réalisation décrits ci-dessus et représentés sur les figures annexées, la fente 12 est délimitée par des flasques latéraux. Il s'agit donc d'une fente centrale unique apte à recevoir un organe de verrouillage 15 possédant un corps unique. Toutefois, les mêmes fonctions peuvent être assurées et les mêmes résultats peuvent être obtenus en prévoyant une variante du dispositif d'accrochage muni d'un unique flasque central, définissant deux fentes latérales situées de part et d'autre dudit flasque unique, et dont l'organe de verrouillage est conformé sous forme d'un cavalier apte à chevaucher le flasque central avec ses deux jambes engagées dans les deux fentes latérales respectives.It may also be noted that, in the embodiments described above and represented in the appended figures, the slot 12 is delimited by lateral flanges. It is therefore a single central slot capable of receiving a locking member 15 having a single body. However, the same functions can be ensured and the same results can be obtained by providing a variant of the hooking device provided with a single central flange, defining two lateral slots situated on either side of said single flange, and of which the 'locking member is shaped as a rider adapted to overlap the central flange with its two legs engaged in the two respective side slots.

Comme il va de soi et comme il résulte d'ailleurs déjà ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus particulièrement envisagés ; elle en embrasse au contraire toutes les variantes.As goes without saying and as already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more particularly envisaged; on the contrary, it embraces all its variants.
