DescriptionDescription
Titre de l'invention : Ecrou débrayableTitle of the invention: Releasable nut
[0001] Sur les chantiers de B-TP, lors de rutilisation de tours d’échafaudage ou d’étaiement, figure 1, le lien entre le sol et la tour se fait par l’intermédiaire de vérins (2) qui permettent une mise à niveau de l’ensemble. Le réglage en hauteur est obtenu par la rotation des écrous (3) sur les fûts (4) filetés des vérins. En général le réglage ou le déréglage sont longs et fastidieux, ceci à cause du grand nombre de tours que l’on doit faire. Cette opération est grandement facilitée si on dispose d’écrous débrayables. Très longtemps, le débrayage des écrous de vérins a été obtenu en écartant la partie taraudée de l’écrou de la partie filetée de la vis.On construction sites of B-TP, when reusing scaffolding towers or shoring, Figure 1, the link between the ground and the tower is through cylinders (2) which allow a setting level of the whole. The height adjustment is obtained by rotating the nuts (3) on the drums (4) threaded cylinders. In general the adjustment or the adjustment are long and tedious, this because of the large number of turns that one has to make. This operation is greatly facilitated if you have disengageable nuts. For a very long time, the disengagement of the cylinder nuts was obtained by moving the threaded part of the nut away from the threaded part of the screw.
[0002] C’est ainsi, sur la solution illustrée par les figures 3 et 4, on distingue un cylindre (6) sur lequel on a pratiqué à mi hauteur un alésage axial de diamètre légèrement supérieur au diamètre de la vis, l’autre partie du cylindre est taraudée au pas de la vis (5). L’ensemble est fendu un certain nombre de fois (7) sur presque toute sa hauteur. Les lamelles résultantes sont enserrées dans une bague (8) de telle sorte que lorsque la bague est en haut, l’écrou est débrayé: les lamelles taraudée ne sont plus en contact avec la vis, réciproquement, lorsque la bague est en bas l’écrou est embrayé: les lamelles taraudées sont en contact avec la vis. Cette solution est peu fiable principalement parce que il est difficile de bouger la bague sans outil.Thus, on the solution illustrated in Figures 3 and 4, there is a cylinder (6) on which we practiced at mid-height an axial bore of diameter slightly greater than the diameter of the screw, the other part of the cylinder is tapped with the pitch of the screw (5). The assembly is split a number of times (7) over almost its entire height. The resulting strips are enclosed in a ring (8) so that when the ring is at the top, the nut is disengaged: the threaded strips are no longer in contact with the screw, conversely, when the ring is at the bottom. nut is engaged: the threaded strips are in contact with the screw. This solution is unreliable mainly because it is difficult to move the ring without tools.
[0003] Une deuxième solution est illustrée sur la figure 5. On y distingue la vis (9) et l’écrou (10) à une oreille. Cet écrou est muni d’une pédale (11) articulée avec un ressort de rappel. L’extrémité de la pédale a quelques portions de taraudage. Lorsque l’on serre la pédale sur l’oreille, on déconnecte l’écrou des pas de vis, de telle sorte que l’écrou devient libre.A second solution is illustrated in Figure 5. We can see the screw (9) and the nut (10) in one ear. This nut is provided with a pedal (11) articulated with a return spring. The end of the pedal has a few tapping portions. When the pedal is tightened on the ear, the nut is disconnected from the screw threads, so that the nut becomes free.
Cette solution est principalement utilisée pour les échafaudages en aluminium. Le principal inconvénient de ce système de débrayage est que la charge n’est reprise que par les quelques portions de taraudage, ce qui ne rend pas la solution très fiable.This solution is mainly used for aluminum scaffolding. The main drawback of this declutching system is that the load is only taken up by the few tapping portions, which does not make the solution very reliable.
Notre invention vise à palier ces difficultés et inconvénients; dans une première réalisation illustrée sur la figure 6 en vue de face notre dispositif est constitué de deux pièces:Our invention aims to overcome these difficulties and disadvantages; in a first embodiment illustrated in FIG. 6 in front view, our device consists of two parts:
- Ecrou à oreilles (12) pour tours d’échafaudage ou d’étaiement constitué de deux parties identiques articulées grâce à un trou percé dans une oreille de chaque partie (13).- Wing nut (12) for scaffolding or shoring towers made up of two identical parts articulated thanks to a hole drilled in one ear of each part (13).
- d’un dispositif pouvant maintenir l’ensemble fermé (14), il s’agit d’une bague de fermeture en forme de cloche.- a device which can keep the assembly closed (14), it is a closing ring in the shape of a bell.
La figure (9) représente, en perspective l’ensemble du dispositif. On y distingue:Figure (9) shows the whole device in perspective. There are:
- les deux parties identiques de l’écrou en position débrayé (15)- the two identical parts of the nut in the disengaged position (15)
- la bague de fermeture (14)- the closing ring (14)
- la vis (17)- the screw (17)
- La bague de maintien en position relevée (14)- The retaining ring in the raised position (14)
- Les deux demi-écrous (15) séparés mais articulés grâce à un axe introduit dans le trou de chaque oreille (16), cet axe peut être un rivet ou un boulon.- The two separate half-nuts (15) but articulated thanks to an axis introduced into the hole of each ear (16), this axis can be a rivet or a bolt.
Pour éviter que les deux pièces articulées n’échappent à la vis, à l’extrémité de chaque demi-écrou est pratiquée une butée (18) qui limite ainsi l’angle d’ouverture des deux pièces.To prevent the two articulated parts from escaping from the screw, a stop (18) is made at the end of each half-nut, which thus limits the opening angle of the two parts.
[0004] D’autre part, le bord intérieur de chaque demi-écrou comporte est taillé en biais aigu (19) de telle sorte que les demi-écrous puissent s’agripper à l’un à l’autre.On the other hand, the inner edge of each half-nut comprises is cut at an acute bias (19) so that the half-nuts can grip each other.

[0005] Mise en œuvreImplementation
1) la tour et la bague de maintien sont légèrement soulevés afin de dégager la partie haute de l’écrou, bossage central.1) the tower and the retaining ring are slightly raised in order to release the upper part of the nut, central boss.
2) les deux demis écrous sont écartés.2) the two half nuts are separated.
3) l’écrou est positionné à la hauteur requise.3) the nut is positioned at the required height.
4) la bague de maintien est redescendue sur le bossage central.4) the retaining ring is lowered onto the central boss.
