Description

L'invention concerne un verrou de fixation de barre diagonale d'échafaudage.The invention relates to a scaffold diagonal bar attachment lock.

On sait que les extrémités des barres diagonales de liaison des échafaudages sont fixées aux montants d'échafaudage, généralement au moyen de vis ou similaire montées traversantes dans l'extrémité des barres diagonales et dans les montants d'échafaudage. Cette liaison peut se relâcher dans le temps, les vis se dévissant, ce qui conduit à du jeu dans la fixation, et même à un risque de perte de la liaison au desserrement total d'une des vis.It is known that the ends of the diagonal connecting bars of the scaffolds are attached to the scaffold posts, usually by means of screws or the like mounted through the ends of the diagonal bars and the scaffold posts. This connection can loosen over time, the screws being unscrewed, which leads to play in the fixing, and even to a risk of loss of connection to the total loosening of one of the screws.

L'invention vise à remédier à cet inconvénient et propose un verrou de fixation de barre diagonale d'échafaudage comportant au moins un élément de tige monté traversant dans l'extrémité de barre diagonale et dans un montant de l'échafaudage au point de leur liaison, caractérisé en ce qu'il est formé d'une tige d'un seul tenant convenablement pliée pour comporter une partie d'axe tournée vers l'intérieur et formant ledit élément de tige reçu par la barre diagonale et le montant d'échafaudage, une partie d'aile reliée par pliage à ladite partie d'axe et se développant sensiblement en boucle ouverte vers l'intérieur avec un pli de retour terminal, ladite partie d'aile et pli de retour étant aptes à être reçus en position relevée par le montant, pour s'y engager tandis que la partie d'axe est introduite dans l'extrémité de barre diagonale et dans le trou de montant à un point de liaison déterminé, le pli de retour étant en outre formé avec un pli tourné vers l'intérieur à prise derrière le montant, apte à verrouiller par serrage au-delà d'un point dur le verrou au montant lorsque ladite partie d'aile est abaissée sur le montant, engagée autour de sa paroi.The invention aims to remedy this drawback and proposes a scaffold diagonal bar fastening lock comprising at least one rod element mounted through the end of the diagonal bar and in an amount of the scaffold at the point of their connection. characterized in that it is formed of a one-piece rod suitably folded to comprise an inward-facing axis portion and forming said stem member received by the diagonal bar and the scaffolding post, a wing portion foldably connected to said axle portion and developing substantially in an inwardly open loop with a terminal return fold, said wing portion and return fold being receivable in the raised position by the amount, to engage there while the axle portion is introduced into the diagonal bar end and into the stud hole at a determined connection point, the return fold being further formed with a turn bend inwardly engages behind the amount, suitable for locking by clamping beyond a hard point when the lock to the amount said wing part is lowered on the amount, engaged around its wall.

Il résulte de cette disposition que le verrou selon l'invention peut être monté simplement en introduisant son pli d'axe dans le trou d'extrémité de barre diagonale et dans le trou de montant, tandis que la partie d'aile est relevée pour passer sur le montant, puis de descendre manuellement ou laisser tomber par gravité la partie d'aile avec son pli de retour autour du montant, le point dur en serrage sur la paroi du montant verrouillant la liaison, laquelle est également maintenue naturellement par gravité, par la masse de la partie d'aile abaissée.It follows from this provision that the lock according to the invention can be mounted simply by introducing its axis fold in the diagonal bar end hole and in the stud hole, while the wing portion is raised to pass. on the upright, then down manually or drop by gravity the wing part with its return crease around the upright, the hard point tightening on the wall of the amount locking the link, which is also maintained naturally by gravity, by the mass of the wing part lowered.

La liaison est donc réalisée rapidement, étant maintenue constamment sans jeu et il suffit de relever manuellement la partie d'aile hors du montant pour permettre de libérer la liaison de la barre diagonale au montant par le verrou.The connection is thus made quickly, being maintained constantly without play and it is enough to manually raise the part wing out of the amount to allow to release the connection of the diagonal bar to the amount by the lock.

Ladite partie d'aile est avantageusement formée d'un premier segment issu d'un pli à angle droit de la partie d'axe et d'un second segment plié à angle droit du premier segment et développé parallèlement à la partie d'axe, au moins sur sa longueur ou proche, ce second segment étant relié audit pli de retour terminal tourné vers l'intérieur et dont la forme est adaptée à la section du montant pour le coiffer à la descente par sa paroi arrière, avec serrage au delà du point dur.Said wing portion is advantageously formed of a first segment resulting from a right angle fold of the axis portion and a second segment bent at right angles to the first segment and developed parallel to the axis portion, at least along its length or near, this second segment being connected to said inwardly facing terminal return ply, the shape of which is adapted to the section of the upright for styling it downwards by its rear wall, with tightening beyond the hard point.

Le verrou est avantageusement issu d'un fil dur, par exemple en acier de 6 à 8 mm d'épaisseur.The lock is advantageously derived from a hard wire, for example steel 6 to 8 mm thick.

La partie d'aile peut encore être conformée en forme générale de boucle avec un pli de retour, adaptée à la section de forme variable du montant d'échafaudage (ronde ou rectangulaire etc...).The wing portion may further be shaped in the general shape of a loop with a return crease, adapted to the section of variable shape of the scaffolding amount (round or rectangular etc ...).

Naturellement, la partie d'axe est prévue légèrement plus longue que l'ensemble des épaisseurs du montant et de l'extrémité associée de la barre diagonale, pour dépasser légèrement du montant au montage.Naturally, the axle portion is provided slightly longer than all the thicknesses of the upright and the associated end of the diagonal bar, to slightly exceed the amount of mounting.

Le verrou peut comporter une rondelle d'appui fixée à l'extrémité interne de la partie d'axe, à proximité de la partie d'aile, cette rondelle venant en appui sur l'extrémité de la barre diagonale au montage.The lock may comprise a bearing washer attached to the inner end of the axis portion, near the wing portion, the washer bearing on the end of the diagonal bar assembly.

Le pli de retour est incliné relativement au plan de la boucle avec une distance du plan légèrement supérieure au diamètre ou à la section du montant, pour permettre l'introduction et la réception de la partie d'aile autour du montant.The return ply is inclined relative to the plane of the loop with a distance from the plane slightly greater than the diameter or section of the upright, to allow introduction and reception of the wing portion around the upright.

Enfin, le pli tourné vers l'intérieur peut comporter un pli interne, par exemple en arrondi s'appliquant à la descente du pli d'aile derrière le montant relativement à son trou d'introduction, et légèrement au-delà de sa partie de section la plus éloignée du trou d'introduction.Finally, the fold facing inwardly may comprise an internal fold, for example rounded, applying to the descent of the wing fold behind the upright relative to its insertion hole, and slightly beyond its portion of the furthest section of the introductory hole.

L'invention est illustrée ci-après à l'aide d'un exemple de réalisation et en référence au dessin annexé, sur lequel :

  • La figure 1 est une vue en élévation d'un verrou selon l'invention,
  • La figure 2 montre le verrou en cours de montage sur l'extrémité d'une barre diagonale et un montant d'échafaudage, et
  • La figure 3 montre le verrou monté sur le montant et la barre diagonale de liaison.
The invention is illustrated below with the aid of an exemplary embodiment and with reference to the appended drawing, in which:
  • FIG. 1 is an elevational view of a lock according to the invention,
  • Figure 2 shows the latch being mounted on the end of a diagonal bar and a scaffolding post, and
  • Figure 3 shows the latch mounted on the upright and the diagonal link bar.

Avec référence au dessin et en particulier à la figure 1, le verrou 1 de fixation de barre diagonale 3 d'échafaudage 5 selon l'invention est constitué d'une tige métallique dure (en acier) 7 convenablement pliée pour comprendre une partie d'axe 9 et une partie d'aile 11.With reference to the drawing and in particular to Figure 1, the lock 1 Scaffold diagonal bar fastener 5 according to the invention consists of a hard metal rod (steel) 7 suitably folded to include an axle portion 9 and a wing portion 11.

La partie d'axe 9 est un segment rectiligne destiné à être reçu traversant dans un trou de perçage de l'extrémité de barre diagonale 3 et dans un trou de perçage du montant d'échafaudage 13 au point de fixation de la barre diagonale sur l'échafaudage, les trous de barre diagonale et de montant d'échafaudage étant complémentaires au jeu près du diamètre de la tige de verrou 7 (de section ronde régulière).The axle portion 9 is a rectilinear segment intended to be received through a drilling hole in the diagonal bar end 3 and in a drilling hole of the scaffolding post 13 at the point of attachment of the diagonal bar to the scaffolding, the diagonal bar holes and scaffold amount being complementary to the play near the diameter of the lock rod 7 (of regular round section).

Une rondelle d'appui 15 est fixée à l'extrémité interne de la partie d'axe 9, cette rondelle 15 étant destinée à venir contre la barre diagonale 3 au montage.A bearing washer 15 is fixed to the inner end of the axle portion 9, this washer 15 being intended to come against the diagonal bar 3 assembly.

La longueur de la partie d'axe 9 est légèrement supérieure à la somme des épaisseurs de l'extrémité de la barre diagonale 3 et du montant 13, au niveau de leur trou traversant de sorte que l'extrémité du segment de la partie d'axe 9 dépasse légèrement au montage du montant 13.The length of the axle portion 9 is slightly greater than the sum of the thicknesses of the end of the diagonal bar 3 and the upright 13, at their through hole so that the end of the segment of the part of axis 9 slightly exceeds the mounting of the amount 13.

La partie d'aile 11 est à forme de boucle, étant destinée à recevoir intérieurement au montage le montant 13. Elle comporte un premier segment 17 plié à angle droit du segment d'axe 9, un second segment 19 plié à angle droit du premier segment 17 et parallèle au segment d'axe 9, et un pli de retour terminal 21 développé sensiblement en forme de S transversalement audit second segment 19.The wing portion 11 is in the form of a loop, being intended to internally receive the upright 13. It comprises a first segment 17 folded at right angles to the axis segment 9, a second segment 19 folded at right angles to the first segment 17 and parallel to the axis segment 9, and a terminal return fold 21 developed substantially S-shaped transverse to said second segment 19.

Le pli de retour 21 est destiné à venir contre la paroi arrière du montant (opposée à celle de l'application de la barre diagonale) lorsque la partie d'aile 11 est ramenée d'une position levée (flèche vers le haut) à une position abaissée (flèche vers le bas), figures 2 et 3, où elle serre contre la paroi du montant par un point dur, à l'extrémité interne 23 du S et se verrouille légèrement au-delà avec maintien vers le bas du verrou sur le montant par un effet d'encliquetage élastique au dépassement du point dur sur le montant 13.The return fold 21 is intended to come against the rear wall of the upright (opposite to that of the application of the diagonal bar) when the wing portion 11 is brought from a raised position (upward arrow) to a lowered position (downward arrow), Figures 2 and 3, where it closes against the wall of the amount by a hard point, at the inner end 23 of the S and locks slightly beyond with holding down the lock on the amount by an elastic latching effect when the hard point is exceeded on the amount 13.

Le fonctionnement est simple et rapide.The operation is simple and fast.

Il suffit d'introduire le segment d'axe 9 du verrou dans le trou de l'extrémité de la barre diagonale 3 puis de l'introduire dans un trou de montant au point de fixation prévu de la barre diagonale tout en levant la partie d'aile 11 pour permettre la réception du montant 13 par celle-ci. On enfonce à fond de course le segment d'axe 9 jusqu'à faire porter la rondelle d'appui 15 contre la barre diagonale 3, elle-même appliquée contre le montant. A ce moment, il suffit de relâcher la partie d'aile 11 qui retombe alors naturellement sur le montant, son pli de retour 21 s'appliquant contre la paroi arrière du montant. Il suffit alors d'exercer une légère pression vers le bas sur la partie d'aile 11 pour permettre de dépasser le point dur d'application sur le montant et réaliser (figure 3) le verrouillage de positionnement du verrou sur le montant. La liaison est alors obtenue et pour la libérer, il suffit de faire la manoeuvre inverse à celle de montage précitée.It is sufficient to introduce the pin 9 segment of the lock into the hole of the end of the diagonal bar 3 and then to introduce it into a stud hole at the planned point of attachment of the diagonal bar while raising the part of wing 11 to allow the receipt of the amount 13 by it. The axle segment 9 is pushed all the way down until it is pushed the support washer 15 against the diagonal bar 3, itself applied against the amount. At that moment, it suffices to release the wing portion 11 which then naturally falls on the upright, its return crease 21 pressing against the rear wall of the upright. It is then enough to exert a slight downward pressure on the wing portion 11 to allow to exceed the hard point of application on the upright and realize (Figure 3) locking the positioning of the lock on the amount. The link is then obtained and to release it, it is sufficient to do the reverse maneuver to the aforementioned mounting.

Il est à noter à titre de variante de réalisation que la partie d'aile peut avoir une forme variable adaptée à la section du montant d'échafaudage.It should be noted as an alternative embodiment that the wing portion may have a variable shape adapted to the section of the scaffold amount.
