Abstract

Longitudinally flexible foldable drawbar, intended for connecting a person to a trolley or other device for transporting a load by human traction. It consists of two tubes 1 and 4 sliding in one another and connected by an elastic link 2 held under tension by a "V"-shaped component 3, the assembly providing flexibility in tension and in compression. A lockable articulation 8 and 5 makes it possible to fold the drawbar through 180 DEG .

Description

L'invention a pour objet une demande d'addition au brevet principal 84 08 985 et concerne un timon souple longitudinalement, repliable pour limiter son encombrement, destiné à relier une personne à un chariot ou autres dispositifs pour le transport d'une charge par traction humaine. Les enfants en période de scolarité ont souvent des cartables avoisinant les 10 Kgs ce qui est excessif pour leur âge; aussi est-il préférable de transporter cette charge en la roulant au moyen d'un chariot relie à l'utilisateur par un timon souple. The subject of the invention is a request for addition to the main patent 84 08 985 and relates to a longitudinally flexible drawbar, foldable to limit its size, intended to connect a person to a trolley or other devices for transporting a load by traction. human. Schoolchildren often have school bags of around 10 kg which is excessive for their age; it is therefore preferable to transport this load by rolling it by means of a trolley connected to the user by a flexible drawbar.

La conception de ce timon apporte la légèreté et un faible encombrement, permettant à l'utilisateur de transporter manuellement ltensemble pour franchir un obstacle (escaliers, accès aux transports en commun ou particuliers). The design of this drawbar brings lightness and a small footprint, allowing the user to manually transport the whole to overcome an obstacle (stairs, access to public or private transport).

Ce timon est constitue de deux tubes coulissant l'un dans l'autre; le tube extérieur est compose de deux sections reliées entre-elles par une articulation verrouillable, permettant de le plier en deux parties lorsqu'il n'est pas utilisé, et ainsi limiter l'encombrement. L'une des extrémités comporte une pièce en forme de " V " munie à ses extrémités d'un lien élastioue sous tension traversant le tube intérieur. Cette liaison assure la souplesse à la compression et à la traction. This drawbar consists of two tubes sliding one inside the other; the outer tube is made up of two sections connected to each other by a lockable joint, allowing it to be folded into two parts when it is not in use, thereby limiting its size. One end has a "V" shaped piece provided at its ends with a tensioned elastic link passing through the inner tube. This connection provides flexibility in compression and traction.

Le déplacement du tube intérieur par rapport au tube extérieur est limité par un lien souple non élastique reliant l'articulation du tube extérieur à I'extr8mit8 du tube intérieur. L'articulation est constitue de deux pièces cylindriques, chacune solidaire de chaque section du tube ext8rieur, reliées par un plot élastique formant charnière, noyée de moitie dans chacune d'elles. The displacement of the inner tube relative to the outer tube is limited by a flexible, non-elastic link connecting the articulation of the outer tube to the end of the inner tube. The articulation consists of two cylindrical parts, each integral with each section of the outer tube, connected by an elastic stud forming a hinge, embedded in half in each of them.

L'axe de ce plot ne coincide pas avec l'axe des deux pièces qu'il relie de manière que le pliage du timon se fasse dans un secteur preferentiel. Une bague coulissant sur le tube exterieur assure le verrouillage de l'articulation.The axis of this stud does not coincide with the axis of the two parts that it connects so that the folding of the drawbar is done in a preferential sector. A sliding ring on the outer tube locks the joint.

LE figure I reprnsente le timon en plan. Figure I shows the drawbar in plan.

La figure 2 reprOsente l'articulation en plan. Figure 2 shows the joint in plan.

La figure 3 représente le timon en coupe partielle. Figure 3 shows the drawbar in partial section.

La figure 4 représente l'articulation en coupe. Figure 4 shows the joint in section.

Les figures représentent un timon souple longitudinalement, repliable pour-limiter son encombrement. The figures represent a flexible drawbar longitudinally, foldable to limit its size.

Ce timon est constitue d'un tube extérieur en dewv parties 4, 7 dans lequel coulisse un tube I. This drawbar consists of an outer tube in dewv parts 4, 7 in which a tube I slides.

La section de tube 4 comporte une pièce 3 en forme de 7. Les extrmités du " V " sont reliées par un lien elastinue 9 sous tension traversant le tube intérieur I. Les deux parties du tube extrier 4. 7 sont relies par une articulation, verrouillable par une bague 5 venant prendre appui sur une bague 6 solidaire du tube 7. The tube section 4 comprises a part 3 in the form of 7. The ends of the "V" are connected by an elastinue link 9 under tension passing through the inner tube I. The two parts of the outer tube 4. 7 are connected by a joint, lockable by a ring 5 coming to bear on a ring 6 integral with the tube 7.

Cette articulation est constituee de deux pièces cylindriques I0, II reliees par un plot de caoutchouc 8 formant charnière noyb dans chacune des pièces I@, II. L'extrémité du tube intérieur I est muni d'un lien souple non elastique 9 relié à la pièce II limitant la course du tube intérieur I. This articulation consists of two cylindrical parts I0, II connected by a rubber pad 8 forming a hinge embedded in each of the parts I @, II. The end of the inner tube I is provided with a non-elastic flexible link 9 connected to the part II limiting the stroke of the inner tube I.

Cet objet est particulièrement destine à equiper des chariots ou autres dispositifs pour le transport de charges légères. This object is particularly intended to equip trolleys or other devices for the transport of light loads.

Tous moyens techniques equivalents, pouvant être utilises pour realiser l'invention font partie intégrante de celle-ci.  All equivalent technical means which can be used to carry out the invention form an integral part of it.
