I1 doit être bien entendu, toutefois, que ces dessins et les parties descriptives correspondantes, sont donnés uniquement à titre d'illustration de l'objet de l'invention, dont ils ne constituent en aucune manière une limitation. It should be understood, however, that these drawings and the corresponding descriptive parts, are given solely by way of illustration of the subject of the invention, of which they do not in any way constitute a limitation.

Le chariot conforme à l'invention, représenté aux dessins, comprend un châssis porteur 1 qui est monté sur une partie 2.d'une plateforme en deux parties 2 et 3 articulées entre elles. The trolley according to the invention, shown in the drawings, comprises a carrying frame 1 which is mounted on a part 2. of a platform in two parts 2 and 3 hinged together.

La partie 2 qui est montée sur un essieu 4 muni de roues 5, peut pivoter sur cet essieu 4 pour modifier la position angulaire des deux parties 2 et 3 articulées sur un axe 6. Part 2 which is mounted on an axle 4 fitted with wheels 5, can pivot on this axle 4 to modify the angular position of the two parts 2 and 3 articulated on an axis 6.

-La partie 3 est composée de deux longerons articulés sur l'axe 6 à l'une de leurs extrémités, l'autre extrémité, qui porte une pièce de protection 22 en matériau approprié, tel que caoutchouc, plastique ou autre, étant pourvue d'une roulette 7 montée dans une chape 8 pivotante. -Part 3 is composed of two longitudinal members articulated on the axis 6 at one of their ends, the other end, which carries a protective part 22 of suitable material, such as rubber, plastic or other, being provided with 'a caster 7 mounted in a swivel yoke 8.

Le châssis 1 est composé de tubes soudés et comporte sur sa face porteuse un plateau élévateur 9 qui coulisse entre des rails 10. Le plateau 9 est relié, par une bielle 11, à un levier 12 monté sur un pivot 13 fixé-sur la partie haute arrière du châssis 1. The chassis 1 is made up of welded tubes and comprises on its carrying face a lifting plate 9 which slides between rails 10. The plate 9 is connected, by a connecting rod 11, to a lever 12 mounted on a pivot 13 fixed on the part high rear of chassis 1.

La bielle Il comporte à sa liaison avec le levier 12, un axe 14 muni de deux roulements à billes 15 qui se déplacent dans une lumière 16 pratiquée dans le levier 12. The connecting rod It comprises, at its connection with the lever 12, an axis 14 provided with two ball bearings 15 which move in a slot 16 formed in the lever 12.

Le plateau 9 est muni, à sa partie inférieure, d'une butée 17 d'amortissement du plateau en position basse et il comporte latéralement des roulements à billes 18 qui se déplacent dans les rails 10. The plate 9 is provided, at its lower part, with a stop 17 for damping the plate in the low position and it comprises laterally ball bearings 18 which move in the rails 10.

Le châssis 1 estrelié à la deuxième partie 3.de la plateforme par une bielle qui est avantageusement constituée par un amortisseur 19 télescopique qui permet d'incliner le châssis sur la plateforme, l'inclinaison maximale étant obtenue quand l'amortisseur télescopique est enfoncé et que les deux parties 2 et 3 articulées sur l'axe 6, sont dans l'alignement l'une de l'autre, comme représenté à la Figure 3.  The chassis 1 is connected to the second part 3. of the platform by a connecting rod which is advantageously constituted by a telescopic damper 19 which makes it possible to tilt the chassis on the platform, the maximum inclination being obtained when the telescopic damper is pressed in and that the two parts 2 and 3 articulated on the axis 6, are in alignment with each other, as shown in Figure 3.

On notera que la partie 3,bye la plateforme peut avantageusement être pourvue latéra ment d'un patin 20 de frein poussé par un ressort 21, ce patin 20 bloquant la roue 5 quand le châssis est en position verticale de charge ment, avec les deux parties 2 et 3 formant un angle entre elles comme représenté à la Figure 1, tandis qu'il libère la roue 5 quand le châssis est incliné et que les parties 2 et 3 sont alignées comme représenté à la Figure 3 : le chariot peut alors se déplacer, la charge portée par le châssis incliné ayant son centre de gravité dont la verticale tombe à l'intérieur du polygone de sustentation formé par les roues 5 et les roulettes 7. Une seule des roues 5 peut être équipée d'un tel frein 20-21, ou chacune des roues 5 peut être équipée d'un tel frein. Note that part 3, bye the platform can advantageously be laterally provided with a brake shoe 20 pushed by a spring 21, this shoe 20 blocking the wheel 5 when the chassis is in the vertical load position, with both parts 2 and 3 forming an angle between them as shown in Figure 1, while it releases the wheel 5 when the chassis is tilted and parts 2 and 3 are aligned as shown in Figure 3: the carriage can then move, the load carried by the inclined chassis having its center of gravity whose vertical falls inside the support polygon formed by the wheels 5 and the rollers 7. Only one of the wheels 5 can be equipped with such a brake 20 -21, or each of the wheels 5 can be equipped with such a brake.

L'on comprendra aisément que l'invention n'est pas limitée au seul mode de réalisation représenté : en particulier l'axe 6 d'articulation entre les deux parties 2 et 3 peut recevoir une goupille amovible de blocage de la position de ces deux parties entre elles, et le chariot pourrait être équipé d'une seule roulette 7 se trouvant dans l'axe médian des roues 6. It will be readily understood that the invention is not limited to the single embodiment shown: in particular the axis 6 of articulation between the two parts 2 and 3 can receive a removable pin for locking the position of these two parts between them, and the carriage could be equipped with a single caster 7 located in the center line of the wheels 6.

De même, le plateau 9 peut être équipé de différents dispositifs de levage de charge tels que le bec 23, une fourche ou autres, adaptés à la charge que l'on veut transporter. Similarly, the plate 9 can be equipped with different load lifting devices such as the spout 23, a fork or the like, adapted to the load that is to be transported.

Ainsi que cela ressort de ce qui précède, l'invention ne se limite nullement à ceux de ses modes de réalisation et d'application qui viennent d'être décrits de façon plus explicite ; elle en embrasse, au contraire, toutes les variantes qui peuvent venir à l'esprit du technicien en la matière, sans s'écarter du cadre, ni de la portée, de la présente invention.  As is apparent from the above, the invention is in no way limited to those of its embodiments and of application which have just been described more explicitly; on the contrary, it embraces all the variants which may come to the mind of the technician in the matter, without departing from the scope, or the scope, of the present invention.
