Abstract

Luggage of the pull-along type comprises a container, a sleeve fixed to the container, and a telescopic tube mounted in a sliding fashion in the sleeve between a retracted position, and a deployed position. The luggage further includes a resilient element interposed between the tube and the sleeve, designed to allow the tube to be pushed into the sleeve beyond the retracted position against a restoring force exerted on the tube by the resilient member.

Description

L'invention a trait aux bagages, et plus précisément aux bagages de type remorquable, couramment appelés trolleys®.The invention relates to luggage, and more specifically towable luggage, commonly called trolleys ® .

Un tel bagage comprend généralement un conteneur, qui forme la partie utile du bagage, un fourreau fixé au conteneur, ainsi qu'une canne généralement munie d'une poignée saillante et montée coulissante dans le fourreau entre une position rétractée, dans laquelle la canne est reçue dans le fourreau pour le portage du bagage ou son stockage, et une position déployée dans laquelle la canne s'étend en porte-à-faux par rapport au fourreau pour faciliter le remorquage du bagage.Such luggage generally comprises a container, which forms the useful part of the luggage, a sheath fixed to the container, and a rod generally provided with a projecting handle and slidably mounted in the sheath between a retracted position, in which the cane is received in the sheath for carrying the baggage or its storage, and an extended position in which the rod extends cantilever relative to the sheath to facilitate the towing of the baggage.

Des bagages remorquables munis de cannes télescopiques sont connus de longue date. Si la canne télescopique améliore l'ergonomie du bagage, elle n'est pas sans poser quelques problèmes pratiques.Towable luggage with telescopic rods has been known for a long time. If the telescopic rod improves the ergonomics of luggage, it is not without posing some practical problems.

Tout d'abord, une telle canne s'avère relativement encombrante. Il a été proposé de la faire disparaître dans le conteneur (voir par exemple la demande de brevet américain US 2002/0096410 ), mais elle empiète alors sur le volume utile du bagage.First, such a cane is relatively bulky. It has been proposed to make it disappear in the container (see for example the US patent application US 2002/0096410 ), but it then encroaches on the useful volume of the luggage.

En second lieu, des utilisations répétées entraînent l'apparition d'un jeu dans le mécanisme de la canne, qui a tendance lors de manipulations brusques (par exemple en milieu aéroportuaire) à sortir intempestivement du fourreau, ce qui peut entraîner sa rupture en cas de choc.Secondly, repeated use leads to the appearance of a game in the mechanism of the cane, which tends during sudden manipulations (for example in the airport environment) to come out of the sheath accidentally, which can cause its break in case of choc.

Il a donc été proposé de rendre la canne encliquetable en position rétractée et de l'intégrer, ainsi que sa poignée, dans le volume du conteneur : la canne est munie d'un verrou à deux positions, à savoir une position de verrouillage dans laquelle le verrou bloque la canne en position rétractée, et une position de déverrouillage dans laquelle il la libère. Une gâchette, actionnable manuellement, provoque la mise du verrou dans sa position déverrouillée, libérant ainsi la canne qui peut être déployée pour permettre le remorquage du bagage. Un déclencheur couplé à des ressorts permet éventuellement de faire sauter la canne hors de son logement pour faciliter sa prise en main en vue du remorquage. A titre d'illustration de ces propos, on pourra se référer aux brevets américains US 5 499 702 , US 5 653 319 , US 5 692 266 , US 5 884 362 et US 5 803 214 .It has therefore been proposed to make the snap-hook rod in the retracted position and to integrate it and its handle into the volume of the container: the rod is provided with a two-position lock, namely a locking position in which the latch locks the rod in the retracted position, and an unlock position in which he releases. A trigger, manually actuatable, causes the lock to be placed in its unlocked position, thereby freeing the rod that can be deployed to allow towing of the luggage. A trigger coupled to springs optionally allows the rod to jump out of its housing to facilitate its grip for towing. As an illustration of these remarks, we can refer to US patents US 5,499,702 , US 5,653,319 , US 5,692,266 , US 5,884,362 and US 5,803,214 .

Ces mécanismes paraissent, à première vue, marquer un progrès en termes de résistance du bagage aux chocs. En pratique, il a été constaté que certaines cannes ont tendance à se fendre, voire se casser, sous certains chocs consécutifs notamment à la chute verticale du bagage. Il arrive même que, par contrecoup, le conteneur soit lui-même endommagé par le mouvement de la canne. En effet, la canne et sa poignée restent exposées à certains chocs, en particulier ceux transmis de la poignée à la canne, même en position rétractée.These mechanisms appear, at first glance, to be an improvement in terms of the resistance of the luggage to shocks. In practice, it has been found that some rods have a tendency to crack or even break under certain consecutive shocks including the vertical fall of the luggage. It even happens that, in turn, the container is itself damaged by the movement of the cane. Indeed, the cane and its handle remain exposed to certain shocks, especially those transmitted from the handle to the cane, even in the retracted position.

Ceci est encore plus vrai lorsque le bagage est semi-rigide ou souple, car le conteneur se déforme plus ou moins sous l'action de contraintes mécaniques ce qui expose d'autant plus la canne et particulièrement sa poignée, en cas de chocs.This is even more true when the luggage is semi-rigid or flexible, because the container is more or less deformed under the action of mechanical stresses which exposes the cane and especially its handle, in case of shocks.

Ainsi, la canne et sa poignée restent exposées à certains chocs, qui sont susceptibles d'entraîner au mieux des disfonctionnements au niveau de la canne ou au pire d'endommager irrémédiablement le bagage.Thus, the cane and its handle remain exposed to certain shocks, which are likely to lead to malfunctions at the rod or at worst irreparable damage to the luggage.

L'invention vise notamment à remédier à ce problème, en proposant un bagage du type remorquable, qui soit moins sensible aux chocs que les bagages connus.The invention aims in particular to remedy this problem, by proposing a luggage of towable type, which is less sensitive to shocks than known baggage.

A cet effet, le bagage proposé, du type précité, comprend les caractéristiques telles que définies dans la revendication 1.For this purpose, the proposed luggage, of the aforementioned type, comprises the features as defined in claim 1.

Ainsi, la canne conserve en position rétractée une certaine course qui lui permet de s'enfoncer sous l'effet d'un choc en particulier vertical, avec un effet d'amortissement du choc procuré par l'organe élastique. Il en résulte une meilleure résistance aux chocs de la canne (et donc, plus généralement, du bagage).Thus, the rod retains in retracted position a certain stroke that allows it to sink under the effect of a particularly vertical shock, with a damping effect of shock provided by the elastic member. This results in better impact resistance of the cane (and therefore, more generally, luggage).

En position rétractée de la canne, l'organe élastique est de préférence précontraint.In the retracted position of the rod, the elastic member is preferably prestressed.

Suivant un mode de réalisation, l'organe élastique comprend au moins un ressort de compression, et de préférence une paire de ressorts de compression. L'organe élastique est par exemple monté dans un support fixé au fourreau.According to one embodiment, the elastic member comprises at least one compression spring, and preferably a pair of compression springs. The elastic member is for example mounted in a support fixed to the sheath.

Suivant un mode de réalisation, l'organe élastique présente une portion inférieure reçue dans un logement ménagé dans le support, et une portion supérieure, dépassant du support et contre laquelle la canne est en appui, cette portion supérieure définissant un jeu entre la canne et le support. Selon une première variante de ce mode de réalisation, il peut suffire que la canne soit en simple appui sur cette portion supérieure. Selon une deuxième variante de ce mode de réalisation, la canne, en position rétractée, comprime l'organe élastique.According to one embodiment, the elastic member has a lower portion received in a housing formed in the support, and an upper portion protruding from the support and against which the cane is in abutment, the upper portion defining a clearance between the cane and the support. According to a first variant of this embodiment, it may be sufficient that the rod is in simple support on this upper portion. According to a second variant of this embodiment, the rod, in the retracted position, compresses the elastic member.

Par ailleurs, la canne peut comprendre des moyens d'encliquetage qui assurent une retenue de la canne en position rétractée ou déployée. Ces moyens d'encliquetage comprennent par exemple une bille, montée dans la canne, sollicitée par un ressort et apte à coopérer avec un trou ménagé dans le fourreau.Furthermore, the cane may comprise snap-fastening means which ensure a retention of the rod in the retracted or deployed position. These latching means comprise for example a ball, mounted in the rod, biased by a spring and adapted to cooperate with a hole in the sleeve.

Plus précisément, la canne peut comprendre un tube extérieur monté coulissant dans le fourreau, ainsi qu'un tube intérieur monté coulissant dans le tube extérieur, le tube extérieur comprenant une bille sollicitée par un ressort et apte à coopérer avec un trou ménagé dans le fourreau, le tube intérieur comprenant quant à lui une bille sollicitée par un ressort et apte à coopérer avec un trou ménagé dans le tube extérieur.More specifically, the rod may comprise an outer tube slidably mounted in the sleeve, and an inner tube slidably mounted in the outer tube, the outer tube comprising a ball biased by a spring and adapted to cooperate with a hole in the sleeve, the inner tube comprising a ball biased by a spring and adapted to cooperate with a hole in the outer tube.

Le conteneur peut être réalisé en un matériau souple ou semi-rigide.The container may be made of a flexible or semi-rigid material.

Other objects and advantages of the invention will become apparent in the light of the description given hereinafter with reference to the appended drawings in which:
  • the figure 1 is a perspective view showing a luggage equipped with a telescopic rod, in the retracted position;
  • the figure 2 is a partial view in section of longitudinal elevation of the luggage of the figure 1 ;

  • the figure 7 is an enlarged view showing detail VII of the figure 6 ; and
  • the figure 8 is an enlarged view showing detail VIII of the figure 6 .

Sur la figure 1 est représenté un bagage 1 du type remorquable, couramment appelé trolley®. Ce bagage 1 comprend un conteneur 2 (représenté en pointillés) en matériau souple, semi-rigide ou rigide, qui constitue le corps du bagage 1, monté et fixé sur un châssis 3 en forme de diable.On the figure 1 is represented a luggage 1 towable type, commonly called trolley ® . This luggage 1 comprises a container 2 (shown in dashed lines) of flexible, semi-rigid or rigid material, which constitutes the body of the luggage 1, mounted and fixed on a frame 3 in the form of a devil.

Le châssis 3 comprend une platine 4 monobloc présentant un socle 5 sur lequel repose le conteneur 2, prolongé par un rebord arrière 6 dans le prolongement duquel s'étendent en saillie deux renforts 7 auxquels est fixé le conteneur 2. Le socle 5 et le rebord 6 sont reliés, de chaque côté, par deux flancs 8 qui forment des passages de roues (non représentées).The chassis 3 comprises a monobloc plate 4 having a base 5 on which the container 2 rests, extended by a rear flange 6 in the extension of which protrude two reinforcements 7 which is fixed the container 2. The base 5 and the flange 6 are connected on each side by two sidewalls 8 which form wheel wells ( not represented).

Comme cela est visible notamment sur les figures 1 et 5, le bagage 1 est en outre équipé d'une canne 9 télescopique dotée d'une poignée saillante et montée coulissante par rapport au châssis 3. La canne télescopique 9 peut être réalisée en une seule pièce ou en plusieurs pièces coulissant l'une dans l'autre, comme représenté sur les dessins.As can be seen in particular on figures 1 and 5 the luggage 1 is furthermore equipped with a telescopic rod 9 having a protruding handle and slidably mounted relative to the frame 3. The telescopic rod 9 may be made in one piece or in several pieces sliding one in the other, as shown in the drawings.

Plus précisément, le châssis 3 comprend un fourreau 10 qui s'étend en saillie à partir du rebord arrière 6, sensiblement perpendiculairement au socle 5. Ce fourreau 10, qui s'étend sur la majeure partie de la hauteur du conteneur 2, est fixé à celui-ci en étant reçu dans une saignée (non représentée) pratiquée dans une paroi arrière 11 du conteneur 2.More specifically, the frame 3 comprises a sleeve 10 which protrudes from the rear flange 6, substantially perpendicularly to the base 5. This sleeve 10, which extends over most of the height of the container 2, is fixed to it by being received in a recess (not shown) formed in a rear wall 11 of the container 2.

Le fourreau 10 comprend une gaine 12 intérieure tubulaire, métallique, dans laquelle la canne 9 est montée coulissante entre deux positions, à savoir :

  • une position rétractée, dans laquelle la canne 9 est reçue dans le fourreau 10 (figures 2, 3), et
  • une position déployée dans laquelle la canne 9 s'étend au moins partiellement en dehors du fourreau 10, en porte-à-faux par rapport à celui-ci (figures 5, 6).
The sheath 10 comprises a tubular inner sheath 12, metal, in which the rod 9 is slidably mounted between two positions, namely:
  • a retracted position, in which the cane 9 is received in the sheath 10 ( figures 2 , 3 ), and
  • an extended position in which the rod 9 extends at least partially outside the sheath 10, cantilevered relative thereto ( figures 5 , 6 ).

Comme cela est visible sur les figures 1, 2 et 5, la canne 9 comprend un tube extérieur 13 creux, reçu dans la gaine 12 en étant monté coulissant par rapport à celle-ci, et un tube intérieur 14, également creux, reçu dans le tube extérieur 13 en étant monté coulissant par rapport à celui-ci.As is visible on the figures 1 , 2 and 5 , the rod 9 comprises a hollow outer tube 13, received in the sheath 12 being slidably mounted relative thereto, and an inner tube 14, also hollow, received in the outer tube 13 being slidably mounted relative to that -this.

A une extrémité inférieure 15, le tube extérieur 13 est solidaire d'un insert 16 emboîté, muni d'un alésage 17 borgne dans lequel est reçu un ressort 18 de compression qui sollicite une bille 19 en direction de la gaine 12. Dans les positions rétractée et déployée de la canne 9, la bille 19 est partiellement reçue dans un trou 20 (respectivement 20'), d'un diamètre inférieur à celui de la bille 19, pratiqué dans la gaine 12 pour assurer la retenue du tube extérieur 13 (en position rétractée, Cf. figure 3, respectivement déployée, Cf. figure 8).At a lower end 15, the outer tube 13 is integral with an insert 16 fitted with a bore 17 blind in which is received a compression spring 18 which urges a ball 19 towards the sheath 12. In the retracted and deployed positions of the rod 9, the ball 19 is partially received in a hole 20 (respectively 20 '), d a diameter smaller than that of the ball 19, made in the sheath 12 to ensure the retention of the outer tube 13 (in retracted position, Cf. figure 3 , respectively deployed, Cf. figure 8 ).

De même, à une extrémité inférieure 21, le tube intérieur 14 comprend un insert 22 emboîté, muni d'un alésage 23 borgne dans lequel est reçu un ressort 24 de compression qui sollicite une bille 25 en direction du tube extérieur 13. Dans les positions rétractée et déployée de la canne 9, la bille 25 est partiellement reçue dans un trou 26 (respectivement 26'), d'un diamètre inférieur à celui de la bille 25, pratiqué dans le tube extérieur 13 pour assurer la retenue du tube intérieur 14 (en position rétractée, Cf. figure 3, respectivement déployée, Cf. figure 7).Similarly, at a lower end 21, the inner tube 14 comprises an insert 22 fitted with a blind bore 23 in which is received a compression spring 24 which biases a ball 25 towards the outer tube 13. In the positions retracted and deployed from the rod 9, the ball 25 is partially received in a hole 26 (26 'respectively), of a diameter smaller than that of the ball 25, formed in the outer tube 13 to ensure the retention of the inner tube 14 (in the retracted position, cf. figure 3 , respectively deployed, Cf. figure 7 ).

Comme cela est bien visible sur la figure 3, les alésages 17, 23 sont orientés à l'opposé l'un de l'autre, de sorte à permettre un relatif équilibrage des efforts internes exercés sur la canne 9.As is clearly visible on the figure 3 , the bores 17, 23 are oriented opposite each other, so as to allow a relative balancing of the internal forces exerted on the rod 9.

La canne 9 se termine, à une extrémité supérieure 27, par une poignée 28 annulaire emboîtée dans le tube intérieur 14 et fixée à demeure à celui-ci.The rod 9 ends, at an upper end 27, by an annular handle 28 nested in the inner tube 14 and permanently attached thereto.

Par ailleurs, comme cela est visible notamment sur les figures 2, 3 et 4, le bagage 1 comporte en outre un organe élastique 29, interposé entre la canne 9 et le fourreau 10, et qui, en position rétractée de la canne 9, exerce sur celle-ci une force de rappel qui la sollicite vers sa position déployée.Moreover, as can be seen in particular in figures 2 , 3 and 4 the luggage 1 further comprises an elastic member 29, interposed between the rod 9 and the sleeve 10, and which, in the retracted position of the rod 9, exerts thereon a restoring force which urges it towards its deployed position.

Suivant un mode de réalisation, et comme représenté sur les figures 3 et 4, l'organe élastique 29 comprend au moins un ressort de compression. En l'occurrence, deux ressorts de compression 29 parallèles sont prévus, montés dans un support 30 commun rapporté, fixé à demeure (par exemple au moyen d'une vis 31) au fourreau 10, au fond de celui-ci.According to one embodiment, and as shown in figures 3 and 4 the elastic member 29 comprises at least one compression spring. In this case, two Compression springs 29 are provided parallel, mounted in a common support reported, fixed (for example by means of a screw 31) to the sheath 10 at the bottom thereof.

En position rétractée de la canne 9, les billes 19, 25 sont encliquetées dans leurs trous 20, 26 respectifs. La canne 9 exerce sur les ressorts 29 une force qui tend à les comprimer au-delà de leur position d'équilibre, la force de rappel des ressorts 29 ainsi précontraints n'étant pas suffisante pour déloger les billes 19, 25 de leurs trous respectifs.In the retracted position of the rod 9, the balls 19, 25 are snapped into their respective holes 20, 26. The rod 9 exerts on the springs 29 a force which tends to compress them beyond their equilibrium position, the restoring force of the springs 29 thus prestressed not being sufficient to dislodge the balls 19, 25 from their respective holes. .

Chaque ressort 29 présente une portion inférieure 32 reçue dans un logement 33 cylindrique complémentaire qui assure à la fois la butée (ou l'accrochage) et le guidage du ressort 29. Comme cela est visible sur les figures 3 et 4, chaque ressort 29 présente une portion supérieure 34 qui dépasse d'une face supérieure 35 du support 30 (du côté de laquelle débouchent les logements 33) et se termine par une extrémité supérieure 36 contre laquelle la canne 9, via une face inférieure 37 de l'insert 16, est en simple appui.Each spring 29 has a lower portion 32 received in a complementary cylindrical housing 33 which provides both the abutment (or the hooking) and the guide of the spring 29. As can be seen on the figures 3 and 4 each spring 29 has an upper portion 34 which protrudes from an upper face 35 of the support 30 (on the side of which the housings 33 open) and ends with an upper end 36 against which the rod 9, via a lower face 37 of the insert 16 is in simple support.

De la sorte, les ressorts 29 définissent, en position rétractée de la canne 9, un jeu J entre celle-ci et le support 30 (plus exactement entre la face inférieure 37 de l'insert 16 et la face supérieure 35 du support 30), ce jeu permettant l'enfoncement de la canne 9 dans le fourreau 10 au-delà de sa position rétractée (comme représenté en pointillés sur la figure 3), à l'encontre de la force de rappel des ressorts 29.In this way, the springs 29 define, in the retracted position of the rod 9, a clearance J between the latter and the support 30 (more exactly between the lower face 37 of the insert 16 and the upper face 35 of the support 30) , this game allowing the depression of the rod 9 in the sleeve 10 beyond its retracted position (as shown in dotted lines on the figure 3 ), against the return force of the springs 29.

De la sorte, la canne 9, dans sa position rétractée, subit, via la poignée 28, un effort (par exemple consécutif à un choc) dirigé notamment parallèlement à sa direction de coulissement et dans le sens de sa rétractation, le jeu J ménagé par les ressorts 29 lui permettent de s'enfoncer de manière élastique. La canne 9 retrouve ensuite, grâce aux ressorts 29, sa position rétractée dès lors que cet effort disparaît.In this way, the rod 9, in its retracted position, undergoes, via the handle 28, a force (for example following a shock) directed in particular parallel to its direction of sliding and in the direction of its retraction, the game J arranged by the springs 29 allow it to sink elastically. The cane 9 then finds, thanks to the springs 29, its retracted position as soon as this effort disappears.

Les ressorts 29 ont par conséquent une fonction d'amortissement des chocs subis par la canne 9, ce qui minimise à la fois les risques d'endommagement (voire de rupture) de celle-ci et la répercussion des chocs au bagage 1 dans son ensemble (au bénéfice de l'intégrité des marchandises qu'il transporte).The springs 29 therefore have a cushioning function of the shocks suffered by the rod 9, which minimizes both the risk of damage (or even rupture) thereof and the impact of the shocks to the luggage 1 as a whole (for the benefit of the integrity of the goods he transports).

Claims (11)

  1. Luggage of the pull-along type, which comprises:
    - a container (2),
    - a sleeve (10), fixed to the container (2),
