Abstract

A sleeve (1) is welded onto a tube (2) into which is fitted another tube (3). The lock is constituted by two lugs (4a,4b) joined by a U-shaped leaf spring (5). In the locked position the two lugs are simultaneously engaged in holes (6a,6b) in the sleeve and in holes (7a,7b) in the tube (3). In order to unlock one presses simultaneously on the lugs to disengage them from the sleeve holes which allows the tube (3) to be withdrawn. The lock remains in this tube held by its lugs which remain engaged in the tube holes.

Description

Dans les constructions tubulaires démontables,et plus partieuliê- restent dans les échafaudages,les étais,les tours d'étaiement etc... In removable tubular constructions, and more particularly, they remain in scaffolding, props, shoring towers, etc.

on rencontre de nombreux dispositifs permettant d'asseabler bout à bout des éléments tubulsires : Platines boulonnées,sanchons avec deux broches,sanchons soudés avec une seule broche,manchons vissés,tubes emboités avec verrouillage par "bonho ~ n à ressort à boudin etc....there are many devices for end-to-end assembly of tubular elements: Bolted plates, sanchons with two pins, sanchons welded with a single pin, screwed sleeves, nested tubes with locking by "bonho ~ n with coil spring etc .. ..

Les platines boulonnées nécéssitent un équerrage parfait,sont onéreuses et longues à assembler. Avec les manchons à une ou deux broches,il y a le risque de perdre la ou les broches,à moins d'utiliser des broches imperdables beaucoup plus onéreuses.De plus,il faut munir les broches d'un verrouillage pour assurer la sécurité.Les manchons avec "bonhomme" à ressort à boudin sont onéreux, difficiles à réaliser et peu fiables à cause de la rouille ou des salissures qui risquent de bloquer le mécanisme. The bolted plates require perfect squaring, are expensive and take a long time to assemble. With one- or two-pin sleeves, you risk losing the pin (s) unless you use much more expensive captive pins, and you must lock the pins to ensure safety. The sleeves with "coil spring" are expensive, difficult to make and unreliable because of rust or dirt which may block the mechanism.

La présente invention répond économiquement le problème et élimine les inconvénients ci-dessus. The present invention economically addresses the problem and eliminates the above drawbacks.

La figure 1 est une coupe longitudinale de deux tubes assemblés bout à bout par le dispositif suivant l'invention. Figure 1 is a longitudinal section of two tubes assembled end to end by the device according to the invention.

La figure 2 est une coupe longitudinale d'un aontant de tour d'étaiement assemblé sur sa plaque de base conformément à l'invention. Figure 2 is a longitudinal section of a prop tower tower assembled on its base plate according to the invention.

La figure 3 est une coupe longitudinale du dispositif d'assemblage de deux montants de tour d'étaiement par un connecteur suivant l'invention. Figure 3 is a longitudinal section of the device for assembling two amounts of shoring tower by a connector according to the invention.

La figure 4 est une vue en élévation de la pièce essentielle du dispositif objet de l'invention. Figure 4 is an elevational view of the essential part of the device object of the invention.

La figure 5 est une coupe longitudinale de cette sese pièce. Figure 5 is a longitudinal section of this piece.

L'assemblage suivant l'invention représenté sur la figure 1 , comporte un manchon 1 soudé sur le tube 2 ,dans lequel vient s'emboiter le tube 3 .Le verrou est constitué par deux ergots 4a et 4b réunis par une lame-ressort 5 en forme de U. En position de serrouillagesles ergots 4a et 4b sont respectivement engagés simultanément dans les trous 6a et 6b percés dans le manchon 1 et dans les trous Ta et 7b percés dans le tube 3 . Pour déverrouiller, on presse simultanément les ergots 4a et 4b pour les dégager des trous 6a et 6b,ce qui permet de retirer le tube 3 dans lequel le verrou reste prisonnier par ses ergots 4a et 4b qui restent engagés dans les trous 7a et 7b du tube 3. The assembly according to the invention shown in Figure 1, comprises a sleeve 1 welded to the tube 2, in which the tube 3 fits. The lock is constituted by two lugs 4a and 4b joined by a leaf spring 5 U-shaped. In the locking position, the pins 4a and 4b are respectively engaged simultaneously in the holes 6a and 6b drilled in the sleeve 1 and in the holes Ta and 7b drilled in the tube 3. To unlock, the lugs 4a and 4b are pressed simultaneously to release them from the holes 6a and 6b, which makes it possible to remove the tube 3 in which the latch remains trapped by its lugs 4a and 4b which remain engaged in the holes 7a and 7b of the tube 3.

Le dispositif objet de l'invention peut servir en particulier à solidariser le montant 8 d'une tour d'étaiement et sa plaque de base amovible 9 dont la tige tubulaire 10 ( qui peut être de section ronde ou carrée ) s 'engage dans le montant tubulaire 8 conge représenté sur la figure 2 La figure 3 représente l'assemblage de deux montants 8a1 et 8a2 d'une tour d'étaiement à l'aide d'un connecteur constitué par un tube tl (de section ronde ou carrée) sur lequel est soudée une butée médiane 12. The device object of the invention can be used in particular to secure the amount 8 of a shoring tower and its removable base plate 9 whose tubular rod 10 (which may be of round or square section) engages in the tubular upright 8 conge shown in Figure 2 Figure 3 shows the assembly of two uprights 8a1 and 8a2 of a shoring tower using a connector constituted by a tube tl (round or square section) on which is welded a central stop 12.

Les montants à assembler 8a1 et 8a2 viennent s'eaboiter sur le tube 11 , en appui sur la butée médiane 12 .Les montants 8a1 et 8a2 possèdent des trous diamètraux en concordance avec ceux du tube 11 , dans lesquels viennent s'engager les ergots 4al , 4bl , 4a2 et 4b2 ,assurant ainsi le verrouillage.The uprights to be assembled 8a1 and 8a2 come to collapse on the tube 11, bearing on the central stop 12 .The uprights 8a1 and 8a2 have diametric holes in accordance with those of the tube 11, in which the pins 4al engage. , 4bl, 4a2 and 4b2, thus ensuring locking.

La figure 4 et le figure 5 représentent un mode de réalisation possible de la pièce essentielle du dispositif t le verrou . Il est constitué par une lame-ressort 5 dont la largeur est fonction de la section du tube intérieur ( circulaire ou carrée) et dont l'épaisseur sera choisie pour que les ergots 4a et 4b soient,en position de verrouillage,fermement maintenus dans les trous 6a et 6b,tout en pet et tant le déverrouillage à la main par une pression raisonnable sur les ergots 4a et 4b.En pratique,pour un tube intérieur carré du 35 - de côté ou un tube intérieur rond de 48 i de disrètre,la largeur de la lame-ressort sera de l'ordre de 20 à 25 - et son épaisseur de l'ordre de 0,1 à 0,2 mm . Figure 4 and Figure 5 show a possible embodiment of the essential part of the device t the lock. It is constituted by a leaf spring 5, the width of which depends on the section of the inner tube (circular or square) and the thickness of which will be chosen so that the pins 4a and 4b are, in the locking position, firmly held in the holes 6a and 6b, while fart and both unlocking by hand by reasonable pressure on the lugs 4a and 4b. In practice, for a square inner tube of 35 - side or a round inner tube of 48 i of disreter, the width of the leaf spring will be of the order of 20 to 25 - and its thickness of the order of 0.1 to 0.2 mm.

Les ergots 4a et 4b peuvent être avantageusement fixés sur la lame- ressort 5 par des rivets 13a et 13b.Mais on peut utiliser tous autres moyens de fixation compatibles avec les matériaux utilisés : Vis , boulons , brasure , colle etc .... The pins 4a and 4b can advantageously be fixed to the leaf spring 5 by rivets 13a and 13b. However, any other fixing means compatible with the materials used can be used: screws, bolts, solder, glue, etc.
