Abstract

The invention relates to an electric golf-bag carrier trolley powered by a battery. This carriage consists of a frame made from metal sheet (1) on which the members necessary for its operation are fastened: two drive wheels (2), a free rear castor (3), a gear motor (5), a battery (6), a control (driving) handle (7). The novel character of the trolley lies in the fact that it automatically adopts two different convenient positions depending on whether it is in stop phase or in movement phase, this being by virtue of a judicious distribution of the weights which make it up. The trolley changes automatically from one to the other of these two positions through the effect of the force of inertia of the assembly on stopping and starting the trolley. Its very compact appearance makes it possible for it to be stored in a small space.

Description

La présente invention est relative à un chariot, porte-sac de golf, rendu auto-moteur par l'intermédiaire d'un moto-réducteur électrique alimenté par une batterie. The present invention relates to a trolley, golf bag holder, made self-propelled by means of an electric gear motor powered by a battery.

Les chariots de ce type, actuellement proposés sur le marché, sont, le plus généralement, de construction tubulaire et comportent, de façon rigide, deux roues motrices à l'arrière et une roulette libre à l'avant. Le sac de golf se présente, en permanence, de façon inclinée, sensiblement à 450.  Trolleys of this type, currently offered on the market, are, most generally, of tubular construction and have, rigidly, two driving wheels at the rear and a free wheel at the front. The golf bag always presents itself in an inclined manner, substantially at 450.

Ces chariots présentent le désavantage d'etre encombrants, ou fragiles quand ils sont démontables ou repliables. These trolleys have the disadvantage of being bulky, or fragile when they are removable or foldable.

La position inclinée du sac ne permet pas d'en extraire commodément les clubs de golf. The inclined position of the bag does not allow golf clubs to be conveniently removed from it.

Le caractère inédit de la présente invention est de proposer un chariot auto-moteur, capable de prendre deux positions différentes et fonctionnelles selon qu'il se trouve en phase d'arret ou en phase de roulement. The novelty of the present invention is to provide a self-propelled carriage, capable of taking two different and functional positions depending on whether it is in the stop phase or in the rolling phase.

La figure 1 représente le chariot en phase d'arrêt. Figure 1 shows the carriage in the stop phase.

La figure 2 représente le chariot en phase de roulement. Figure 2 shows the carriage in the rolling phase.

Ce chariot est constitué d'un chassis (1) en tôle d'aluminium pliée sur lequel viennent se fixer
- Un train de deux roues principales motrices (2),
- Une roulette arrière libre (3), fixée sur le chassis par l'in termédiaire d'un timon (4),
-Un moto-réducteur électrique (5) d'entraînement des roues motrices (2), dont la puissance est modulée par un variateur (12) permettant de régler la vitesse de roulement du chariot à l'allure souhaitée,
- Une batterie électrique (6),
- Un manche de conduite (7), sur lequel est fixée une fourche métallique (11) permettant le maintien du sac dans sa partie supérieure, ce manche étant le seul élément démontable du corps principal du chariot.This trolley consists of a chassis (1) made of folded aluminum sheet on which are fixed
- A two-wheel drive train (2),
- A free rear caster (3), fixed to the chassis by means of a drawbar (4),
-An electric geared motor (5) for driving the driving wheels (2), the power of which is modulated by a variator (12) making it possible to adjust the rolling speed of the carriage at the desired speed,
- An electric battery (6),
- A driving handle (7), on which is fixed a metal fork (11) allowing the bag to be held in its upper part, this handle being the only removable element of the main body of the trolley.

Ce chassis présente, dans sa partie antérieure, une surface plane (13), servant de repos au sac. This chassis has, in its front part, a flat surface (13), serving to rest the bag.

Lorsque le chariot est en position d'arret, il se trouve basculé vers l'avant, et trouve une position de repos sur le sol constituée par par un polygone de sustentation défini par les génératrices inférieures des deux roues motrices (2) et le méplat frontal (8) du chassis. When the carriage is in the stopped position, it is tilted forward, and finds a rest position on the ground formed by a support polygon defined by the lower generators of the two driving wheels (2) and the flat front (8) of the chassis.

Dans cette position, la roulette arrière (3) se trouve décollée du sol et le sac de golf (9) est présenté verticalement, permettant au joueur d'en extraire commodément les clubs (10).  In this position, the rear caster (3) is detached from the ground and the golf bag (9) is presented vertically, allowing the player to conveniently extract the clubs (10).

Dans cette position d'arrêt, la résultante des diverses masses constituées par, le chariot, ses accessoires et le sac rempli de clubs qu'il supporte, passe par un centre de gravité dont la verticale se situe légèrement devant l'axe des deux roues motrices (2), et à l'intérieur du polygone de sustentation défini ci-avant. In this stopped position, the result of the various masses constituted by, the trolley, its accessories and the bag filled with clubs that it supports, passes through a center of gravity whose vertical is located slightly in front of the axis of the two wheels. drive (2), and inside the lift polygon defined above.

Lorsque le chariot est mis en marche, la force d'inertie de l'ensemble des masses se traduit par une composante horizontale dirigée vers l'arrière qui provoque automatiquement le basculement du chariot, l'amenant à venir en repos selon un second polygone de sustentation défini par les génératrices inférieures des deux roues motrices (2) et la génératrice inférieure de la roulette arrière (3) qui prend contact avec le sol. When the carriage is started, the inertial force of all the masses is reflected by a horizontal component directed towards the rear which automatically causes the carriage to tip over, causing it to come to rest in a second polygon of lift defined by the lower generators of the two driving wheels (2) and the lower generator of the rear caster (3) which contacts the ground.

Dans cette position de roulement, la résultante des diverses masses constituées par, le chariot, ses accessoires et le sac rempli de clubs qu'il supporte, passe par un centre de gravité dont la verticale se situe légèrement derrière l'axe des deux roues motrices (2), et à l'intérieur du second polygone de sustentation défini ci-dessus. In this rolling position, the result of the various masses constituted by, the carriage, its accessories and the bag filled with clubs which it supports, passes through a center of gravity whose vertical is located slightly behind the axis of the two driving wheels. (2), and inside the second lift polygon defined above.

Inversement, dès que le moto-réducteur est coupé, la force d'inertie de l'ensemble des masses se traduit par une composante horizontale vers l'avant qui provoque le basculement du chariot vers l'avant, le faisant reposer selon le premier polygone de sustentation défini ci-avant. Conversely, as soon as the gearmotor is cut, the inertial force of all the masses is reflected by a horizontal component towards the front which causes the tilting of the carriage forward, causing it to rest according to the first polygon lift defined above.

L'avantage de ces dispositions réside dans le fait que le chariot est toujours proche d'une position d'équilibre instable, notamment en position de roulement, de telle sorte que le maximum de la charge est supporté par les deux roues motrices (2), ce qui permet une meilleure adhérence du chariot sur le sol. The advantage of these provisions lies in the fact that the carriage is always close to an unstable equilibrium position, in particular in the rolling position, so that the maximum of the load is supported by the two driving wheels (2) , which allows a better grip of the trolley on the ground.

Par ailleurs, ces dispositions qui favorisent la charge maximum sur les deux roues à plus fort diamètre permettent de réduire la résistance de roulement sur le sol, avec pour conséquence, une économie sur la décharge de la batterie et, corrélativement, une amélioration de l'autonomie du chariot. Furthermore, these provisions which promote the maximum load on the two larger diameter wheels make it possible to reduce the rolling resistance on the ground, with as a consequence, an economy on the discharge of the battery and, correspondingly, an improvement in the cart autonomy.

Enfin, le positionnement à l'arrière de la roulette libre (3) permet de réduire l'encombrement du chariot et de le ranger, sans difficulté, par exemple dans le coffre d'une petite voiture, en n'ayant à procéder qu'au seul démontage du manche de conduite (7). Finally, the positioning at the rear of the free wheel (3) makes it possible to reduce the size of the trolley and to store it, without difficulty, for example in the boot of a small car, by having only to carry out when the pipe handle (7) is removed.

Cet encombrement minimum est le fruit d'une recherche de l'équi- librage de l'ensemble très voisin de l'axe des deux roues motrices (2).  This minimum size is the result of a search for the balance of the assembly very close to the axis of the two driving wheels (2).
