Abstract

The device has a connecting unit (L2) connecting a chassis (3b) and a carrier (2) to ensure characteristics that include minimum degree of freedom of a ball-joint connection of an origin point (B), an angle between a segment (AB) connecting the origin points (A, B) and a horizontal plane (H) ranges between 15-75 degrees, the point (B) is not confound with the point (A), and a ratio of length (X-G) to length (X-B) is less than 0.5, where former length is a length between the point (A) and a center of gravity (G) on a horizontal plane (H) and latter length is a length between the points (A, B). The origin point (B) is not confound with the origin point (A) when the segment (AB) is perpendicular to a segment (AC) connecting the origin point (A) and an intersection point (C), and center of gravity (G) is below a normal plane (k).

Description

L'invention concerne un dispositif à un essieu pour maintenir en équilibreThe invention relates to a device with an axle for maintaining a balance

stable une charge quelconque entre un support quelconque et un porteur quelconque. Dans des domaines comme : la poussette d'enfant, le sac et caddy de golf, la brouette, la remorque, le bagage ou porte bagage.  stable any load between any support and any carrier. In areas such as: child stroller, golf bag and caddy, wheelbarrow, trailer, luggage or luggage rack.

Actuellement, ces appareils traditionnels sont encombrantes et/ou lourds et/ou chers et/ou difficiles à plier et/ou peu stable et/ou peu maniable. De plus, chacun de ces besoins nécessitent un appareil dédié, ce qui augmente les coûts et l'embarra. Le dispositif selon l'invention permet de remédier à ces inconvénients. Il est un moyen sécuritaire et maniable, pour faciliter le déplacement d'une charge. Cela en étant léger, compact, fiable et peu cher. De plus, cette invention se prête particulièrement à être multifonction. Le dispositif comporte selon une première caractéristique au moins une roue, un chassis et une liaison avec le porteur. Le dispositif repose sur la combinaison de caractéristiques suivantes : 1) La liaison entre l'invention et le porteur est au minimum une liaison rotule. 2) Dans la configuration la plus défavorable, l'ensemble du dispositif avec sa charge est pendulaire entre le support et le porteur. 3) Dans la configuration la plus défavorable, la force de maintien du porteur est inférieure à la moitié du poids de l'ensemble du dispositif plus la charge. 4) Le dispositif est pliant.  Currently, these traditional devices are bulky and / or heavy and / or expensive and / or difficult to bend and / or unstable and / or unwieldy. In addition, each of these needs requires a dedicated device, which increases costs and embarks. The device according to the invention overcomes these disadvantages. It is a safe and manageable way to facilitate the movement of a load. This being light, compact, reliable and inexpensive. In addition, this invention is particularly suitable for being multifunctional. The device comprises according to a first characteristic at least one wheel, a chassis and a connection with the carrier. The device is based on the following combination of features: 1) The connection between the invention and the carrier is at least a ball joint connection. 2) In the most unfavorable configuration, the entire device with its load is pendulum between the support and the carrier. 3) In the most unfavorable configuration, the carrier holding force is less than half the weight of the entire device plus the load. 4) The device is folding.

Selon des modes particuliers de réalisation : • Le chassis peut comporter une poignée directrice, sensiblement perpendiculaire à l'axe pendulaire. II est alors possible de diriger le dispositif en mode propulsion (poussette). • Le dispositif peut être adaptés à des charges spécifiques. • La partie conteneur du dispositif peut être escamotable. 30 Le conteneur escamotable peut être adaptés à des charges spécifiques. 35 40 45 2911841 2- Les dessins annexés illustrent l'invention : FIG.01 : configuration la plus défavorable pour la stabilité, [AC] perpendiculaire à [AB] FIG.02 : 3P bagage plié FIG.03 : 3P bagage déplié 5 FIG.04 : 3P bagage en utilisation propulsion ou traction FIG.05 : 3P en utilisation propulsion, poignée directionnelle (3b1) parallèle à p FIG.06 : 3P en utilisation propulsion, poignée directionnelle (3b1) perpendiculaire à p FIG.07 : Châssis (3c) de 3P multi-usages plié (vue de face) FIG.08 : Châssis (3c) de 3P multi-usages en cours de déploiement (vue de face) 10 FIG.09 : Châssis (3c) de 3P multi-usages déplié (vue de face) FIG.10 : idem (vue de gauche) FIG.11 : 3P multi-usages avec conteneur escamotable (3c1) FIG.12 : 3P multi-usages avec conteneur escamotable (3c2) FIG.13 : 3P GOLF en mode utilisation avec 7 clubs en face avant (vue de face) 15 FIG.14 : idem (vue en perspective) FIG.15 : 3P GOLF plié avec 7clubs en face avant et 1 club en face arrière (vue de face) FIG.16 : idem (vue de gauche) FIG.17 : idem (vue de dessus) 20 30 35 40 45 40 --3- En référence à ces dessins : (0) : SUPPORT (1) : CHARGE (la) : ENFANT (2) : PORTEUR (2a) : PORTEUR HUMAIN (2a1) : MAIN (3) : 3P (3a) : ROUE (3b) : CHASSIS (3b1) : POIGNEE (3c) : CONTENEUR  According to particular embodiments: • The chassis may comprise a steering handle, substantially perpendicular to the pendulum axis.
