Description

La présente invention concerne les bagages munis de roues.The present invention relates to luggage provided with wheels.

On connaît deux systèmes principaux de roulement pour de tels bagages ou valises. Dans un premier système, il est prévu deux roues disposées à une extrémité du fond du bagage et une poignée est articulée au voisinage du coin opposé du bagage, pour le soulever, le tirer et le guider sur ses deux roues. Dans le second système, il est prévu quatre roues disposées deux à deux à chaque extrémité de la valise. Dans ce dernier système, une courroie et une poignée sont utilisées pour faire rouler la valise sur ses quatre roues.Two main rolling systems are known for such baggage or suitcases. In a first system, two wheels are provided arranged at one end of the bottom of the luggage and a handle is articulated in the vicinity of the opposite corner of the luggage, for lifting it, pulling it and guiding it on its two wheels. In the second system, four wheels are provided, arranged in pairs at each end of the bag. In the latter system, a strap and a handle are used to roll the suitcase on its four wheels.

Un problème qui se pose avec les bagages munis de quatre roues résulte du fait que ces roues sont libres, c'est-à-dire qu'elles permettent aux bagages de rouler librement sur le sol. Il en résulte qu'une valise à quatre roues peut rouler librement sur une rampe ou un convoyeur incliné. Selon la pente du convoyeur ou de la rampe et la distance parcourue, la valise peut atteindre des vitesses relativement impor­tantes risquant ainsi de provoquer des dommages sur la valise elle-même, son contenu ou sur d'autres objets et mêmes des personnes, lors d'un choc.A problem which arises with baggage provided with four wheels results from the fact that these wheels are free, that is to say that they allow baggage to roll freely on the ground. As a result, a four-wheeled suitcase can roll freely on a ramp or an inclined conveyor. Depending on the slope of the conveyor or the ramp and the distance traveled, the bag can reach relatively high speeds, thus risking damage to the bag itself, its contents or to other objects and even people, when 'a shock.

Le but de cette invention est par conséquent de perfectionner de tels bagages munis d'éléments de roulement, de façon à pouvoir les freiner et les empê­cher de dévaler des pentes.The object of this invention is therefore to improve such luggage provided with rolling elements, so as to be able to brake it and prevent it from rolling down slopes.

L'invention a ainsi pour objet un bagage mu­ni d'éléments de roulement permettant à ce bagage de se déplacer sur une surface horizontale ou inclinée, comprenant des moyens de traction pour traîner ou pousser le bagage sur ses roues, au moins un organe de portage, ainsi que des moyens pour neutraliser sélectivement au moins certains desdits éléments de roulement lorsqu'on souhaite empêcher un mouvement de roulement incontrôlé, caractérisé en ce qu'il comprend des moyens pour amener les moyens de neutralisation en position active lorsque le bagage est soulevé indé­pendamment de l'organe de traction et pour les amener en position inactive lorsque l'organe de traction est utilisé pour déplacer le bagage.The subject of the invention is therefore a baggage provided with rolling elements allowing this baggage to move on a horizontal or inclined surface, comprising traction means for dragging or pushing the baggage on its wheels, at least one carrying member , as well as means to neutralize selectively at least some of said rolling elements when it is desired to prevent an uncontrolled rolling movement, characterized in that it comprises means for bringing the neutralization means into the active position when the luggage is lifted independently of the traction member and to bring them into the inactive position when the traction device is used to move the luggage.

Les moyens de neutralisation des roues comprennent de préférence une patte dont la dimension est telle que lorsque cette patte se trouve dans une première position, elle empêche les roues de venir en contact avec la surface sur laquelle repose le bagage, tandis que lorsque cette patte occupe une seconde po­sition, les roues peuvent rouler sur le sol. Ainsi qu'on le verra dans le mode de réalisation préféré, les moyens de traction comprennent une courroie et des moyens pour emmagasiner sélectivement cette courroie sous forme d'une boucle. Les moyens de neutralisation des roues peuvent comprendre une biellette reliée à ces moyens d'emmagasinage de la courroie. La biellette coopère avec la patte de façon telle que lorsqu'on exerce une traction sur la courroie, la biellette per­met à la patte de se replier contre la paroi du baga­ge. Lorsque l'extrémité du bagage est soulevée du sol, par exemple en utilisant la poignée de portage, la patte est sollicitée élastiquement de façon à s'éten­dre au-delà des roues, empêchant ainsi ces dernières de venir en contact avec le sol jusquà ce que les moyens d'emmagasinage de la courroie soient à nouveau actionnés.The means for neutralizing the wheels preferably comprise a lug whose dimension is such that when this lug is in a first position, it prevents the wheels from coming into contact with the surface on which the luggage rests, while when this lug occupies a second position, the wheels can roll on the ground. As will be seen in the preferred embodiment, the traction means comprise a belt and means for selectively storing this belt in the form of a loop. The means for neutralizing the wheels may comprise a link connected to these means for storing the belt. The link cooperates with the tab so that when traction is exerted on the belt, the link allows the tab to fold against the wall of the luggage. When the end of the luggage is lifted from the ground, for example by using the carrying handle, the lug is elastically stressed so as to extend beyond the wheels, thus preventing the latter from coming into contact with the ground until that the storage means of the belt are again actuated.

Le bagage ou la valise 10 comprend plusieurs éléments de roulement tels que des roues ou des ga­lets. Une paire de roues avant 12 est disposée du côté de la valise 10 où se trouve également une poignée de traction 16. Une deuxième paire de roues 14 est dispo­sée à la partie arrière de la valise 10, opposée à celle où se trouve ladite poignée 16.The luggage or the suitcase 10 comprises several rolling elements such as wheels or rollers. A pair of front wheels 12 is disposed on the side of the suitcase 10 where there is also a pull handle 16. A second pair of wheels 14 is disposed at the rear part of the suitcase 10, opposite to that where said handle 16 is located .

La valise 10 comprend bien entendu une poi­gnée 18 de portage de réalisation connue. Cette valise 10 comporte également une rainure périphérique 11 qui divise esthétiquement cette valise en deux parties plus petites, tout en délimitant une cavité dans la­quelle peuvent être reçus la poignée 16 de traction, sa courroie déployable qui sera décrite plus en détail ci-dessous, ainsi que le dispositif de freinage selon l'invention. La valise peut également être divisée par cette rainure 11 en une demi-coquille constituant le fond et une demi-coquille constituant le couvercle, le couvercle étant articulé sur le fond au moyen de char­nières 15. En général, les roues avant 12 sont montées de façon à pouvoir pivoter autour d'un axe vertical. De la sorte, la valise 10 peut effectuer des virages lorsqu'elle est traînée par la poignée 16.The suitcase 10 naturally includes a carrying handle 18 of known construction. This suitcase 10 also has a peripheral groove 11 which aesthetically divides this suitcase into two parts smaller, while delimiting a cavity in which can be received the pull handle 16, its deployable belt which will be described in more detail below, as well as the braking device according to the invention. The suitcase can also be divided by this groove 11 into a half-shell constituting the bottom and a half-shell constituting the cover, the cover being articulated on the bottom by means of hinges 15. In general, the front wheels 12 are mounted so that you can rotate around a vertical axis. In this way, the suitcase 10 can make turns when it is dragged by the handle 16.

Dans le dispositif envisagé, une courroie 20 dont l'extrémité supérieure est reliée à la poignée 16, est emmagasinée sous forme d'une boucle dans un carter 17, également disposé dans la rainure périphé­rique 11.In the device envisaged, a belt 20, the upper end of which is connected to the handle 16, is stored in the form of a loop in a casing 17, also arranged in the peripheral groove 11.

La figure 2 représente le coin avant infé­rieur de la valise 10, une partie du carter 17 étant arrachée pour montrer une portion intermédiaire de la courroie de traction 20, qui passe autour d'une boucle mobile 22 constituant un organe de renvoi pour la courroie 20. La boucle 22 est reliée par un coulisseau 24, un ressort 26 et un câble 28 au mécanisme de frei­nage 30. Le câble 28 est de préférence du type à gaine pour lui permettre de se déplacer aisément dans la rainure 11, autour du coin avant inférieur de la va­lise 10. Le coulisseau 24 est guidé par un téton fixe 24a.FIG. 2 represents the lower front corner of the suitcase 10, a part of the casing 17 being cut away to show an intermediate portion of the traction belt 20, which passes around a movable loop 22 constituting a return member for the belt 20 The loop 22 is connected by a slide 24, a spring 26 and a cable 28 to the braking mechanism 30. The cable 28 is preferably of the sheath type to allow it to move easily in the groove 11, around the front corner. lower of the bag 10. The slide 24 is guided by a fixed stud 24 a .

Le mécanisme de freinage 30 comprend une em­base 32 qui est fixée par des vis ou des rivets dans la rainure 11. L'embase délimite deux lumières 34 dans lesquelles une tige (ou axe) 36 peut à la fois pivoter et se déplacer en translation. La tige 36 porte aussi l'extrémité supérieure d'une biellette de support 38 et une extrémité d'une navette 44 (figure 3).The braking mechanism 30 comprises a base 32 which is fixed by screws or rivets in the groove 11. The base delimits two slots 34 in which a rod (or axis) 36 can both pivot and move in translation. Rod 36 also carries the upper end of a support rod 38 and one end of a shuttle 44 (Figure 3).

L'embase supporte à rotation une deuxième tige ou axe 40 qui est elle-même fixée à une première extrémité d'une patte 42 formant béquille destinée à venir en contact avec le sol. Le câble 28 est fixé à la navette 44 qui peut se déplacer le long de l'embase 32 sur une courte distance sous l'effet du mouvement du câble 28 et des forces s'exerçant sur l'extrémité inférieure de la patte 42. La navette 44 porte à une extrémité la tige 36 et la biellette de support 38. La gaine du câble 28 est en appui, d'une part, contre une butée de gaine 29 fixée dans le fond de la rainure 11 et d'autre part, contre la patte 42 ou contre une autre butée de gaine.The base rotatably supports a second rod or axis 40 which is itself fixed to a first end of a tab 42 forming a stand intended to come into contact with the ground. The cable 28 is fixed to the shuttle 44 which can move along the base 32 for a short distance under the effect of the movement of the cable 28 and of the forces exerted on the lower end of the tab 42. shuttle 44 carries at one end the rod 36 and the support rod 38. The sheath of the cable 28 is in abutment, on the one hand, against a sheath stop 29 fixed in the bottom of the groove 11 and on the other hand, against lug 42 or against another sheath stop.

A l'extrémité inférieure de la biellette 38 est prévu un petit ressort de torsion 48. Ce ressort exerce une certaine force qui tend à déplacer l'extré­mité supérieure de la biellette 38 vers la droite, le long de la fente 34, en regardant les figures. La force exercée par ce ressort 48 peut être facilement vaincue par le mouvement de la navette 44 sous l'effet d'un déplacement vers le haut du coulisseau 24, trans­mis par le câble 28.At the lower end of the link 38 is provided a small torsion spring 48. This spring exerts a certain force which tends to move the upper end of the link 38 to the right, along the slot 34, looking at the figures. The force exerted by this spring 48 can be easily overcome by the movement of the shuttle 44 under the effect of an upward displacement of the slide 24, transmitted by the cable 28.

Le fonctionnement du dispositif de freinage 30 va être expliqué plus en détail en se référant aux figures 4A à 4C. La figure 4A montre le dispositif de freinage 30 dans ce qui peut être considéré comme sa position normale, la patte 42 étant en contact avec le sol, alors que les roues sont également en contact avec le sol. Dans cette position, la patte 42 n'est sollicitée que par la force élastique exercée par le ressort de torsion 48. Cette patte n'a ainsi qu'un effet de freinage négligeable et la valise 10 peut se déplacer librement sur ses quatre roues. De légères inégalités à la surface du sol peuvent faire que la patte 42 tourne autour de la deuxième tige ou du deu­xième axe 40. La tige 36 se déplace librement le long de la partie centrale 34a des surfaces de came cons­tituées par les lumières 34. Cette partie lisse des lumières 34 n'empêche pas ce léger déplacement.The operation of the braking device 30 will be explained in more detail with reference to FIGS. 4A to 4C. FIG. 4A shows the braking device 30 in what can be considered to be its normal position, the lug 42 being in contact with the ground, while the wheels are also in contact with the ground. In this position, the lug 42 is stressed only by the elastic force exerted by the torsion spring 48. This lug thus has only a negligible braking effect and the suitcase 10 can be move freely on all four wheels. Slight inequalities in the ground surface may be that the lug 42 is rotated around the second shaft or the second axis 40. The rod 36 moves freely along the central part 34 has cam surfaces 34 formed by the lights. This smooth part of the lights 34 does not prevent this slight displacement.

Par contre, lorsqu'un effet de freinage est souhaité, l'utilisateur soulève légèrement du sol la valise 10 au moyen de la poignée de portage 18. Ceci permet au ressort de torsion 48 d'amener la tige 36 dans sa position extrême vers la droite dans les lu­mières 34. Comme on le voit sur la figure 4b, ceci amène la tige 36 à passer dans une partie 34b de la surface de came des lumières 34 qui est orientée ver­ticalement. Lorsque la valise 10 est reposée sur le sol, l'extrémité de la patte 42 est maintenue au-des­sous de la surface inférieure des roues avant 12, les maintenant éloignées du sol et les neutralisant par conséquent. La tige 36 est verrouillée dans la partie d'extrémité 34b des lumières 34. Dans cette position du dispositif, la valise est empêchée de rouler sur le sol. De préférence, toutefois, l'agencement est tel que si l'utilisateur s'assied sur le bagage, la patte 42 cède élastiquement suffisamment pour que les roues viennent à nouveau reposer sur le sol et supportent le poids de l'utilisateur.On the other hand, when a braking effect is desired, the user lifts the suitcase 10 slightly from the ground by means of the carrying handle 18. This allows the torsion spring 48 to bring the rod 36 in its extreme position towards the straight in the lights 34. As can be seen in FIG. 4b, this causes the rod 36 to pass through a part 34b of the cam surface of the lights 34 which is oriented vertically. When the suitcase 10 is rested on the ground, the end of the lug 42 is kept below the lower surface of the front wheels 12, keeping them away from the ground and consequently neutralizing them. The rod 36 is locked in the end portion 34 b of the lights 34. In this position of the device, the bag is prevented from rolling on the ground. Preferably, however, the arrangement is such that if the user sits on the luggage, the lug 42 yields sufficiently resiliently so that the wheels come to rest again on the ground and support the weight of the user.

Lorsque l'utilisateur de la valise souhaite revenir à une position de libre roulement, par exemple pour pouvoir tirer la valise au moyen de la poignée 16, il lui suffit de tirer la courroie 20, en exerçant une traction sur la poignée 16. Ceci provoque le dé­placement du coulisseau 24 vers le haut. Le câble 28 est actionné et la navette 44 est déplacée vers la gauche en regardant la figure 3. Ceci dégage la tige 36 de sa position verrouillée dans les lumières 34 et entraîne le retrait de la patte 42 qui est ainsi éloi­gnée du sol et pénètre au moins en partie dans la rai­nure 11 (figure 4G). La valise 10 peut alors être uti­lisée comme si aucun mécanisme de freinage n'existait. Elle peut se déplacer librement sur ses roues avant 12 et arrière 14.When the user of the bag wishes to return to a free rolling position, for example in order to be able to pull the bag by means of the handle 16, it suffices for him to pull the strap 20, by exerting traction on the handle 16. This causes moving the slide 24 upwards. The cable 28 is actuated and the shuttle 44 is moved towards the left looking at Figure 3. This releases the rod 36 from its locked position in the slots 34 and causes the withdrawal of the tab 42 which is thus remote from the ground and penetrates at least partly in the groove 11 (Figure 4G). Suitcase 10 can then be used as if no braking mechanism existed. It can move freely on its front 12 and rear 14 wheels.

Lorsqu'on relâche la poignée de traction, le câble 28 n'est plus sous tension et la patte 42 peut revenir dans sa position représentée sur la figure 4A. Aucun effort de freinage n'est exercé dans cette posi­tion. Ce n'est que lorsque les roues 12 sont soule­vées, par exemple au moyen de la poignée 18, que la patte 42 peut descendre suffisamment bas vers le sol pour permettre à la tige 36 portée par la biellette 38, de tomber dans la branche 34b de verrouillage des lumières 34. Par conséquent, la poignée de traction 16, qu'elle soit constituée par une courroie simple ou par la courroie déployable selon le mode de réalisa­tion représenté, peut être utilisée en liaison avec la poignée de portage 18 pour actionner le dispositif de freinage et l'amener en position active ou inactive.When the pull handle is released, the cable 28 is no longer under tension and the tab 42 can return to its position shown in FIG. 4A. No braking force is exerted in this position. It is only when the wheels 12 are raised, for example by means of the handle 18, that the lug 42 can descend sufficiently low towards the ground to allow the rod 36 carried by the link 38, to fall into the branch 34 b for locking the lights 34. Consequently, the pull handle 16, whether constituted by a simple strap or by the deployable strap according to the embodiment shown, can be used in conjunction with the carrying handle 18 to actuate the braking device and bring it to the active or inactive position.

Le mouvement de la navette 44 peut également être contrôlé, selon que le couvercle de la valise est ouvert ou fermé. Dans le mode de réalisation représen­té, dans lequel le mécanisme de freinage est reçu dans la rainure périphérique 11, il est important que la patte 42 ne gêne pas avec l'ouverture de la valise. A cet effet, un plongeur 50 est prévu pour pouvoir se déplacer latéralement entre une première position dans laquelle il fait saillie sur une certaine distance à travers une ouverture 54 ménagée dans la paroi laté­rale de l'embase 32, et une seconde position dans laquelle il est à peu près de niveau avec l'ouverture 54. Un ressort 58 est prévu dans l'extrémité infé­rieure creuse du plongeur 50, pour solliciter ce plongeur vers sa première position. Un doigt 52 for­mant toucheau de came fait saillie latéralement à partir du côté du plongeur 50, ce doigt pouvant nor­malement entrer en contact avec une surface de came inclinée 46 délimitée par le bord d'un orifice ménagé dans la face inférieure de la navette 44. L'extrémité supérieure du plongeur 50 vient en contact avec la surface supérieure de la rainure 11 lorsque le couvercle est fermé. Cependant lorsque le couvercle est ouvert, le ressort 58 sollicite le plongeur 50 vers le haut au-delà de l'ouverture 54.The movement of the shuttle 44 can also be controlled, depending on whether the cover of the case is open or closed. In the embodiment shown, in which the braking mechanism is received in the peripheral groove 11, it is important that the tab 42 does not interfere with the opening of the bag. For this purpose, a plunger 50 is provided to be able to move laterally between a first position in which it projects a certain distance through an opening 54 formed in the side wall of the base 32, and a second position in which it is approximately level with the opening 54. A spring 58 is provided in the hollow lower end of the plunger 50, to urge this plunger towards its first position. A finger 52 forming a cam touch protrudes laterally from the side of the plunger 50, this finger normally being able to come into contact with an inclined cam surface 46 delimited by the edge of an orifice formed in the underside of the shuttle 44. The upper end of the plunger 50 comes into contact with the upper surface of the groove 11 when the cover is closed. However, when the cover is open, the spring 58 biases the plunger 50 upwards beyond the opening 54.

Normalement, l'extrémité supérieure du plon­geur 50 est poussée vers le bas par la venue en con­tact avec un côté de la rainure 11, porté par le couvercle de valise. Ceci éloigne le doigt 52 de la surface de came inclinée 46 prévue sur la navette 44. Toutefois, lorsque le couvercle de la valise est ou­vert par articulation autour des charnières 15, le plongeur se déplace vers le haut à travers l'orifice 54. Le doigt 52 peut se déplacer sous l'effet de l'action du ressort 58 et vient en contact avec la surface inclinée de la came 46 pour déplacer la na­vette 44 et son axe 36 vers l'avant dans les lu­mières 34. Ceci a pour effet de rétracter la patte 42 et de la ramener dans la rainure 11. De la sorte, la patte 42 est amenée dans une position telle qu'elle ne gêne pas l'ouverture de la valise 10, ce qui serait le cas si elle pouvait rester dans sa position déployée.Normally, the upper end of the plunger 50 is pushed downwards by coming into contact with one side of the groove 11, carried by the suitcase cover. This moves the finger 52 away from the inclined cam surface 46 provided on the shuttle 44. However, when the cover of the case is opened by articulation around the hinges 15, the plunger moves upward through the orifice 54. The finger 52 can move under the action of the spring 58 and comes into contact with the inclined surface of the cam 46 to move the shuttle 44 and its axis 36 forward in the slots 34. This has the effect retract the tab 42 and bring it back into the groove 11. In this way, the tab 42 is brought into a position such that it does not hamper the opening of the suitcase 10, which would be the case if it could remain in its deployed position.

La figure 5 représente un dispositif de freinage simplifié analogue à celui décrit précédem­ ment. Dans ce mécanisme, l'axe de rotation de la patte 42a est décalé de 90° par rapport à celui représenté dans le premier mode de réalisation. Les surfaces de came des lumières 34 sont remplacées par un simple franchissement de point mort de la patte 42a. Un ressort 48a maintient normalement la patte 42a dans une position située au-delà de la position de point mort. Un câble 28a est fixé à l'extrémité libre d'un bras de levier 44a qui est fixé à l'axe d'articulation solidaire de la patte 42a et qui détermine donc la position de cette patte. Lorsqu'on tire sur la cour­roie, comme dans le premier mode de réalisation dé­crit, le mouvement de cette courroie est transmis par le câble 28a. Cependant, dans ce mode de réalisation, ce déplacement est transformé en une force de rotation qui provoque le basculement de la patte de freinage, à l'encontre de la force moins importante exercée par le ressort 48a.FIG. 5 represents a simplified braking device similar to that described above. is lying. In this mechanism, the axis of rotation of the tab 42 a is offset by 90 ° relative to that shown in the first embodiment. The cam surfaces of the lights 34 are replaced by a simple crossing of neutral point of the tab 42 a . A spring 48 a normally maintains the tab 42 a in a position located beyond the neutral position. A cable 28 a is fixed to the free end of a lever arm 44 a which is fixed to the articulation axis integral with the lug 42 a and which therefore determines the position of this lug. When the belt is pulled, as in the first embodiment described, the movement of this belt is transmitted by the cable 28 a . However, in this embodiment, this displacement is transformed into a rotational force which causes the braking tab to tilt, against the less significant force exerted by the spring 48 a .

La figure 6A représente le mécanisme dans la position pour laquelle sous l'effet du ressort 48a, la patte 42a est légèrement en contact avec le sol et ne provoque pratiquement pas de force de freinage. Sur la figure 6B, la force exercée par le ressort 48a amène la patte 42a dans sa position déployée, après que la valise ait été légèrement soulevée au moyen de la poi­gnée de portage. Le poids de la valise 10 bloque ef­fectivement la patte 42a dans sa position en contact avec le sol, au-delà de la position de point mort, neutralisant ainsi les roues 12 qui ne sont plus en contact avec le sol. En exerçant une traction sur la courroie, comme expliqué à propos du premier mode de réalisation, on provoque une traction sur le câble 28a et cet effort de traction est transformé par action sur le bras de levier 44a en une force de rotation supérieure à la force exercée par le ressort 48a. De la sorte, en soulevant au moins l'extrémité de la valise au moyen de la courroie de traction, la patte 42a peut tourner sous l'effet de la force exercée par le levier 44a. Ceci dégage complètement (la patte 42a du sol comme représenté sur la figure 6C. La valise peut alors se déplacer librement sur ses quatre roues comme un bagage classique.FIG. 6A represents the mechanism in the position for which, under the effect of the spring 48 a , the tab 42 a is slightly in contact with the ground and practically does not cause any braking force. In FIG. 6B, the force exerted by the spring 48 a brings the tab 42 a into its deployed position, after the bag has been slightly raised by means of the carrying handle. The weight of the bag 10 effectively blocks the lug 42 has in its position in contact with the ground, beyond the dead center position, thereby neutralizing the wheels 12 which are no longer in contact with the ground. By exerting traction on the belt, as explained in connection with the first embodiment, traction is caused on the cable 28 a and this tensile force is transformed by action on the lever arm 44 a into a rotational force greater than the force exerted by the spring 48 a . In this way, by lifting at least the end of the bag by means of the traction belt, the tab 42 a can rotate under the effect of the force exerted by the lever 44 a . This completely clears (the tab 42 has ground as shown in FIG. 6C. The suitcase can then move freely on its four wheels like conventional luggage.

Comme dans le premier mode de réalisation décrit, celui de la figure 5 comprend également des moyens pour empêcher le mécanisme de freinage d'inter­férer avec l'ouverture du couvercle. A cet effet, l'axe de la charnière 15a reliant le couvercle au fond de la valise est disposé à peu près au niveau du point d'articulation de la patte 42a. Etant donné que cette dernière tourne autour d'un axe parallèle à l'axe des charnières de la valise, le couvercle vient simplement en contact avec la partie supérieure de la patte 42a lorsqu'il est en position d'ouverture. La force d'ou­verture du couvercle est supérieure à la force exercée par le ressort 48a et provoque par conséquent le bas­culement de la patte pour l'éloigner du couvercle.As in the first embodiment described, that of Figure 5 also includes means for preventing the braking mechanism from interfering with the opening of the cover. To this end, the axis of the hinge 15 a connecting the cover to the bottom of the bag is disposed approximately at the point of articulation of the tab 42 a . Since the latter rotates about an axis parallel to the axis of the hinges of the bag, the cover simply comes into contact with the upper part of the tab 42 a when it is in the open position. The opening force of the cover is greater than the force exerted by the spring 48 a and consequently causes the tab to tilt to move it away from the cover.

Dans la variante de la Fig. 7, le mécanisme de liaison et d'actionnement entre la poignée de trac­tion et les moyens de freinage 150 sont disposés à l'intérieur du bagage, dans un boîtier 117. De plus, la sangle 120 comporte trois brins qui passent sur deux organes de renvoi, l'un non visible sur le dessin, correspondant à l'organe 22, et l'autre désigné par la référence 122a. Cet organe 122a est, lui-aussi, sollicité par un ressort 127.In the variant of FIG. 7, the link and actuation mechanism between the traction handle and the braking means 150 are arranged inside the luggage, in a housing 117. In addition, the strap 120 has three strands which pass over two members of reference, one not visible in the drawing, corresponding to the member 22, and the other designated by the reference 122 a . This member 122 a is also biased by a spring 127.

La variante représentée à la Fig. 8 cor­respond à une version simplifiée du mode de réali­sation des Fig. 1 à 4. On y retrouve : une embase 201 délimitant deux lumières 202; une biellette 203 comportant deux doigts coaxiaux 204, venus de matière, reçus dans les lumières 202; et une patte 205 formant béquille articulée sur l'embase autour d'un axe 206 et sur la biellette 203 autour d'un axe 207. L'axe des doigts 204 et les axes 206, 207 sont parallèles. Un ressort à lame 208 sollicite la patte 205 vers sa position active, cette patte portant un patin 205a.The variant shown in FIG. 8 corresponds to a simplified version of the embodiment of FIGS. 1 to 4. We find there: a base 201 delimiting two lights 202; a link 203 comprising two coaxial fingers 204, made of material, received in the slots 202; and a tab 205 forming a stand articulated on the base around an axis 206 and on the link 203 around an axis 207. The axis of the fingers 204 and the axes 206, 207 are parallel. A leaf spring 208 biases the tab 205 towards its active position, this tab carrying a pad 205 a .

Le câble d'actionnement 209 est accroché sur la biellette 203, au voisinage de l'axe formé par les doigts 204.The actuation cable 209 is hung on the link 203, in the vicinity of the axis formed by the fingers 204.

Le fonctionnement du dispositif de freinage est analogue à celui décrit à propos du mode de réalisation des Fig. 1 à 4.The operation of the braking device is similar to that described in connection with the embodiment of FIGS. 1 to 4.

On a représenté aux Fig. 9 à 11 une variante des moyens de commande 210 qui permettent d'amener la patte de freinage en position escamotée lors de l'ouverture du couvercle, de tels moyens étant mis en oeuvre avec le mode de réalisation de la Fig. 8 des moyens de freinage.There is shown in Figs. 9 to 11 a variant of the control means 210 which make it possible to bring the brake lug into the retracted position when the cover is opened, such means being used with the embodiment of FIG. 8 braking means.

Ces moyens sont disposés au voisinage du point d'accrochage entre la courroie de traction 211 et le câble d'actionnement 209. Le courroie 211 agit sur un coulisseau 212 logé dans un boîtier 213, ce boîtier recevant de plus deux leviers 214 et 215 montés rotatifs autour d'un même axe 214a.These means are arranged in the vicinity of the point of attachment between the traction belt 211 and the actuating cable 209. The belt 211 acts on a slide 212 housed in a housing 213, this housing also receiving two levers 214 and 215 mounted rotatable around the same axis 214 a .

Le levier 214 a une extrémité qui fait saillie dans le coulisseau 212 et sur laquelle est fixée l'extrémité du câble d'actionnement 209.The lever 214 has one end which projects into the slide 212 and on which the end of the actuation cable 209 is fixed.

Le levier 215 comporte un rebord 216 qui peut venir en appui contre le levier 214 et une partie 217 qui fait saillie hors du boîtier 213 pour venir sur le trajet d'une partie du couvercle du bagage (non représenté). Un ressort 218 sollicite le levier 215 vers la position représentée sur la Fig. 10.The lever 215 has a rim 216 which can come to bear against the lever 214 and a part 217 which projects out of the housing 213 to come into the path of a part of the luggage cover (not shown). A spring 218 biases the lever 215 towards the position shown in FIG. 10.

Le fonctionnement de ce mécanisme est le suivant : en position fermée du couvercle, le levier 215 occupe la position de la Fig. 10 et le levier 214 est soumis aux actions du câble 209 et de la courroie 211, permettant le fonctionnement normal du dispo­sitif.The operation of this mechanism is as follows: in the closed position of the cover, the lever 215 occupies the position of FIG. 10 and the lever 214 is subjected to the actions of the cable 209 and the belt 211, allowing the normal operation of the device.

Lorsque le couvercle est ouvert, le levier 215 bascule vers sa position de la Fig. 9 sous l'action du ressort 218, et agit sur le levier 214 pour exercer une traction sur le câble 209 et amener la patte de freinage en position rétractée.When the cover is open, the lever 215 switches to its position in FIG. 9 under the action of the spring 218, and acts on the lever 214 to exert traction on the cable 209 and bring the brake lug to the retracted position.

L'expression organe de traction doit être comprise comme désignant aussi un organe utilisé pour déplacer le bagage par poussée et la courroie 20 peut être remplacée par tout lien équivalent.The expression traction member must be understood as also designating a member used to move the baggage by pushing and the belt 20 can be replaced by any equivalent link.
