Abstract

Device for aiding with fitting and removing so-called earth mover tyres, characterised in that it comprises a straight rigid arm 9 one free end 12 of which is contrived to allow it to be fastened to the periphery of the wheel rim and the other end of which is fixed at a point of a support chassis 1 the base of which is intended to rest on the ground, and means are provided so as, when the base 14 of the said support 1 rests on the ground, to bring the said arm 9 into the horizontal position at a given distance from the said ground.

Description

La présente invention a pour objet un dispositif d'aide au montage et démontage de pneus dits de génie civil, c'est-à-dire de pneus de grandes dimensions, par exemple de l'ordre de 2 m de diamètre, montés sur jante plate.The subject of the present invention is a device for assisting in the mounting and dismounting of so-called civil engineering tires, that is to say tires of large dimensions, for example of the order of 2 m in diameter, mounted on a rim. flat.

Le montage et le démontage de ces pneus très lourds, de l'ordre de 200 à 300 kg par exemple, s'opèrent, sans démontage de la roue, en faisant glisser le pneu, à la main, sur la jante plate, après enlèvement des cercles, ou pièces analogues, de retenue du pneu.The assembly and disassembly of these very heavy tires, of the order of 200 to 300 kg for example, takes place, without disassembly of the wheel, by sliding the tire, by hand, on the flat rim, after removal tire retaining rings or the like.

On conçoit facilement que cette manoeuvre, pénible, est délicate du fait qu'il est difficile d'éviter le coincement du pneu. En effet, dès que le premier talon du pneu est écarté de la jante, le pneu a tendance à se mettre en biais, en empêchant le glissement des talons inférieurs sur la
Jante.
It is easy to see that this painful maneuver is delicate because it is difficult to avoid the tire jamming. Indeed, as soon as the first bead of the tire is moved away from the rim, the tire tends to be biased, preventing the sliding of the lower bead on the
Rim.

L'invention vise à faciliter cette manoeuvre et elle prévoit à cet effet, de fournir un dispositif caractérisé par le fait qu'il comprend un bras rigide rectiligne dont une extrémité libre est agencée pour permettre son accrochage à la périphérie de la jante et dont l'autre extrémité est fixée en un point d'un châssis support dont la-base est destinée à reposer sur le sol et des moyens sont prévus pour, lorsque la base dudit support repose sur le 501, amener ledit bras en position horizontale, à une distance déterminée dudit sol.The invention aims to facilitate this maneuver and it provides for this purpose, to provide a device characterized in that it comprises a rigid rectilinear arm whose free end is arranged to allow its attachment to the periphery of the rim and whose l other end is fixed at a point on a support frame, the base of which is intended to rest on the ground and means are provided for, when the base of said support rests on the 501, bringing said arm to a horizontal position, at a determined distance from said ground.

Un tel dispositif permet, on le voit, d'accrocher ltextré- mité libre dudit bras à la jante du pneu à monter ou démonter, et de faire glisser manuellement le pneu sur la barre horizontale du dispositif de l'invention, sans risque de coincement. Such a device makes it possible, as can be seen, to hang the free end of said arm on the rim of the tire to be assembled or removed, and to manually slide the tire on the horizontal bar of the device of the invention, without risk of jamming. .

Dans une de ses formes de réalisation, le bras est relié à une tige perpendiculaire à la base du support et réglable en hauteur par rapport à cette base, par exemple en étant montée coulissante dans un tube fixé au support.In one of its embodiments, the arm is connected to a rod perpendicular to the base of the support and adjustable in height relative to this base, for example by being slidably mounted in a tube fixed to the support.

Pour la facilité du maniement du dispositif, le bras est articulé sur le support pour permettre son repliement contre le support.For ease of handling the device, the arm is articulated on the support to allow it to be folded against the support.

Compte tenu de ce que le dispositif est destiné à être utilisé après accrochage de l'extrémité de son bras, le support peut avantageusement être constitué simplement de deux pieds, éventuellement télescopiques, situés dans un même plan dans lequel peut alors être montée la tige sur laquelle le bras est fixé.Given that the device is intended to be used after hooking the end of its arm, the support can advantageously consist simply of two feet, possibly telescopic, located in the same plane in which the rod can then be mounted on which the arm is fixed.

A titre nullement limitatif, on a représenté au dessin un exemple de réalisation de dispositif selon l'invention, dessin sur lequel : la fig. 1 est une vue en élévation latérale du dispositif, et la fig. 2 est une vue en élévation de face du dispositif de la fig. 1.By way of non-limiting example, there is shown in the drawing an exemplary embodiment of a device according to the invention, drawing in which: FIG. 1 is a side elevational view of the device, and FIG. 2 is a front elevation view of the device of FIG. 1.

Dans cet exemple de réalisation, le dispositif comprend un châssis métallique I constitué de deux éléments tubulaires 2, 2' faisant entre eux un angle d'environ 400, et reliés rigidement l'un à l'autre par deux couples d'entretoisement, 3, 3' et 4, 4 constitués chacun de deux barrettes plates soudées respectivement de chaque coté des deux éléments tubulaires 2, 2'.In this embodiment, the device comprises a metal frame I made up of two tubular elements 2, 2 ′ forming an angle of about 400 between them, and rigidly connected to each other by two couples of bracing, 3 , 3 'and 4, 4 each consisting of two flat bars welded respectively on each side of the two tubular elements 2, 2'.

Entre les entretoises 3, 3t et 4, 4, est enserréeune pièce tubulaire 5 dans laquelle peut coulisser une tige 6 dont le mouvement est commandé par un cric 7. Between the spacers 3, 3t and 4, 4, is clamped a tubular piece 5 in which a rod 6 can slide, the movement of which is controlled by a jack 7.

A l'extrémité supérieure de la tige 6 est articulé, sur l'axe 8, un bras 9 constitué ici d'une barre 10 sur laquelle est soudée une tringle 11 munie à son extrémité libre d'un cran 12 d'accrochage. Une bUtée 13 est montée à l'autre extrémité de la tringle 11.At the upper end of the rod 6 is articulated, on the axis 8, an arm 9 consisting here of a bar 10 on which is welded a rod 11 provided at its free end with a catch 12 notch. A stop 13 is mounted at the other end of the rod 11.

A l'extrémite inférieure des tubes 2, 2' sont montés des pieds télescopiques 14, 14' réglables et blocables par des goupilles 15, 15'.At the lower end of the tubes 2, 2 'are mounted telescopic legs 14, 14' adjustable and lockable by pins 15, 15 '.

Lt utilisation du dispositif pour le montage et le démontage des pneus de "génie civil" résulte immédiatement de ce qui précède
Après levée de la roue, écartant le pneu du sol, et enlèvement du cercle de verrouillage, ou butée, du pneu sur la jante, le cran 12 d'extrémité de la. tringle 11 est accroché sur la partie supérieure de la jante.
The use of the device for mounting and dismounting "civil engineering" tires results immediately from the above
After lifting the wheel, removing the tire from the ground, and removing the locking circle, or stop, of the tire on the rim, the end notch 12 of the. rod 11 is hung on the upper part of the rim.

Pour ce faire, la tige 6 est sortie dune longueur convenable de la pièce tubulaire 5, par manoeuvre du cric 7, et le bras 9 est relevé par pivotément autour de son axe d'articulation 8. Les pieds 14, 14' des éléments tubulaires 2, 2' du châssis 1 étant posés sur le sol, le bras 9 est amené en position sensiblement horizontale, par réglage des pieds 14, 14' et blocage par les goupilles 15, 15t. To do this, the rod 6 has come out of a suitable length from the tubular part 5, by maneuvering the jack 7, and the arm 9 is pivotally raised around its articulation axis 8. The feet 14, 14 ′ of the tubular elements 2, 2 'of the chassis 1 being placed on the ground, the arm 9 is brought into a substantially horizontal position, by adjusting the feet 14, 14' and locking by the pins 15, 15t.

Dans cette position du dispositif, le~pneu est poussé, ou tiré, pour le faire coulisser sur sa jante et amener par
supérieur conséquent son talon/extérieur à reposer sur la tringle 11.
In this position of the device, the ~ tire is pushed, or pulled, to make it slide on its rim and bring by
consequently its heel / outside to rest on the rod 11.

Le glissement du pneu peut se poursuivre sans risque de coincement, car il n'a plus tendance à basculer, étant maintenu vertical par son appui sur le bras 9 horizontal.
Le montage d'un pneu sur sa jante s'opère, avec le dispositif selon l'invention, de manière analogue, les opérations se déroulant en sens inverse de celles qni viennent d'etre décrites.
The sliding of the tire can continue without risk of jamming, since it no longer tends to tip, being kept vertical by its support on the horizontal arm 9.
The mounting of a tire on its rim takes place, with the device according to the invention, in a similar manner, the operations taking place in the opposite direction to those which have just been described.

Exemple de réalisation représenté et décrit représente, on le voit, un dispositif de structure simple et de stabilité assurée. Cette stabilité pourrait être augmentée en prévoyant un châssis à trois pieds.  Example of embodiment shown and described represents, as we can see, a device of simple structure and guaranteed stability. This stability could be increased by providing a three-legged frame.
