Abstract
Description
Chariot d'achats Shopping cart
L'invention concerne les chariots d'achats que les magasins à grande surface mettent à la disposition de leurs clients pour faire leurs emplettes. Le genre de chariots actuellement le plus répandu est constitué d'un socle roulant sur lequel une corbeille est montée fixe, ce qui oblige l'acheteur à effectuer un transvasement des marchandises de la corbeille du chariot dans le coffre de sa voiture. The invention relates to shopping trolleys that big box stores make available to their customers for shopping. The kind of trolleys currently most widespread consists of a rolling base on which a basket is mounted fixed, forcing the buyer to perform a transfer of the goods from the shopping trolley in the trunk of his car.
Il a également été proposé diverses solutions d'accrochage sur un socle roulant de sacs ou corbeilles qui sont la propriété de l'acheteur et qui en raison de cette amovibilité suppriment ce transvasement. Un exemple de solution de ce type est le brevet EP 202135 qui décrit un chariot dont le socle roulant porte en partie supérieure des manchons tubulaires fendus dans lesquels on vient engager les extrémités de baguettes rigides formant les poignées de sacs parallélépipédiques. It has also been proposed various fastening solutions on a rolling base of bags or baskets which are the property of the buyer and which because of this removability remove this transfer. An example of such a solution is the patent EP 202135 which describes a carriage whose rolling base carries in the upper part of the split tubular sleeves in which it comes to engage the ends of rigid rods forming the handles of parallelepiped bags.
Cependant ces systèmes de chariots d'achats à sacs amovibles n'ont connu qu'une diffusion relativement faible, essentiellement en raison de leur contenance limitée. En effet, du fait que les sacs sont maintenus en porte-à- faux dans les manchons, il n'est pas possible avec le système décrit dans le brevet EP 202135 d'équiper les socles roulants de sacs procurant une capacité d'achats comparable à celle des paniers fixes des chariots généralement mis à disposition dans les magasins à grande surface, qui est de l'ordre de 200 à 240 litres, et parfois 300 litres pour les plus volumineux d'entre eux. However, these shopping bag systems have had relatively little diffusion, mainly because of their limited capacity. Indeed, because the bags are held cantilevered in the sleeves, it is not possible with the system described in EP 202135 to equip the wheel bases of bags providing a comparable purchasing capacity to that of the fixed baskets of the trolleys generally made available in the big-box stores, which is of the order of 200 to 240 liters, and sometimes 300 liters for the largest of them.
L'invention vise à procurer un chariot d'achats du type à sacs amovibles qui procurent une grande contenance d'achats tout en restant emboîtables et légers et dans lequel les opérations de mise en place et d'enlèvement des sacs par l'utilisateur s'effectuent de manière très simple et quasi intuitive.The object of the invention is to provide a shopping trolley of the type with removable bags that provide a large volume of purchases while remaining nestable and lightweight and in which the implementation of operations and removal of bags by the user is very simple and almost intuitive.
Dans ce but, l'invention est constituée par un chariot d'achats du type comportant un châssis équipé de roulettes disposées aux extrémités de longerons reliés entre eux par des traverses de manière à former un quadrilatère en forme de pyramide tronquée dont le petit côté est dirigé vers l'avant, lesdits longerons se raccordant à l'opposé dudit petit côté à des montants dont les extrémités supérieures forment un brancard de manœuvre et ledit châssis étant muni de moyens de support pour des sacs amovibles caractérisé en ce que lesdits moyens de support sont constitués par un arbre longitudinal disposé sensiblement au niveau du brancard de manœuvre, s'étendant en porte-à-faux, avec une légère pente montante vers l'avant du châssis, entre les montants arrière et l'extrémité avant du châssis, en ce que le châssis comporte au moins deux traverses superposées sur les montants sensiblement au niveau du brancard de manœuvre, en ce que ledit arbre est fixé sur la traverse inférieure et repose en position de service sur la traverse supérieure et en ce que ledit arbre coopère avec des moyens d'accrochage agencés sur des sacs amovibles. For this purpose, the invention consists of a shopping trolley of the type comprising a chassis equipped with rollers arranged at the ends of spars interconnected by cross members so as to form a truncated pyramid-shaped quadrilateral whose short side is directed towards the front, said longitudinal members connecting opposite said small side to amounts whose upper ends form a maneuvering stretcher and said frame being provided with support means for removable bags characterized in that said support means are constituted by a longitudinal shaft disposed substantially at the maneuvering stretcher, extending cantilevered, with a slight slope rising towards the front of the frame, between the rear uprights and the front end of the frame, that the frame comprises at least two sleepers superimposed on the uprights substantially at the stretcher, in that said shaft is f fixed on the lower rail and rests in the service position on the upper rail and in that said shaft cooperates with hooking means arranged on removable bags.
La combinaison d'une structure de châssis en forme de pyramide tronquée avec un arbre légèrement penté vers le haut qui supporte des sacs en porte- à-faux procure l'emboîtabilité des chariots les uns dans les autres sans frottement ni coincement lorsque les sacs sont enlevés. La fixation de l'arbre sur une traverse inférieure et son appui sur une traverse supérieure entre les montants arrière du chariot contrarie le fléchissement de l'arbre en charge et répartit les efforts sur toute la structure, ce qui lui permet de supporter de lourdes charges tout en restant de construction très simple. Cet arbre procure une mise en place des sacs amovibles par simple dépose de l'ouverture des sacs sur les moyens d'accrochage dont la barre est munie.The combination of a truncated pyramid-shaped frame structure with a slightly upwardly sloping shaft that supports cantilevered bags provides nestability of the carriages within each other without friction or jamming when the bags are removed. The fixing of the shaft on a lower cross member and its support on an upper rail between the rear uprights of the truck counteracts the deflection of the load shaft and distributes the forces on the entire structure, which allows it to withstand heavy loads while remaining very simple construction. This tree provides introduction of removable bags simply by removing the opening of the bags on the hooking means which the bar is provided.
Selon un mode de réalisation avantageux, l'arbre de support des sacs est monté à rotation autour d'un axe horizontal disposé entre les montants du châssis. Ainsi, la barre de support des sacs peut pivoter librement vers le haut lorsqu'elle rencontre un obstacle, ce qui facilite l'emboîtement des chariots entre eux. According to an advantageous embodiment, the bag support shaft is rotatably mounted about a horizontal axis disposed between the frame uprights. Thus, the bag support bar can pivot freely upwards when it encounters an obstacle, which facilitates the nesting of the carriages together.
Selon un autre mode de réalisation, une traverse additionnelle est disposée entre les montants du châssis au dessus de la traverse d'appui de l'arbre de support des sacs. Cette disposition a une double fonction : d'une part elle limite la possibilité de débattement de l'arbre vers le haut, ce qui limite le risque de vandalisme, d'autre part, cette traverse additionnelle sert de chevalet pour le montage sur le chariot d'accessoires tel qu'un siège pour bébés, un panier additionnel ou autres. According to another embodiment, an additional cross member is disposed between the frame uprights above the support beam of the support shaft of the bags. This arrangement has a dual function: on the one hand it limits the possibility of deflection of the shaft upwards, which limits the risk of vandalism, on the other hand, this additional cross serves as an easel for mounting on the trolley accessories such as a baby seat, an additional basket or others.
Selon un mode de réalisation préférentiel, pour la coopération de la barre de support avec des sacs amovibles les moyens d'accrochage sont constitués d'une part par des arceaux disposés sur le dessus de la barre et d'autre part par des crochets ou des bandes d'accrochage disposées le long de l'ouverture de sacs amovibles. According to a preferred embodiment, for the cooperation of the support bar with removable bags, the hooking means are constituted on the one hand by arches disposed on the top of the bar and on the other hand by hooks or hooks. fastening strips arranged along the opening of removable bags.
Selon un mode alternatif de réalisation, l'arbre de support des sacs comporte au moins deux paires de barrettes transversales disposées de part et d'autre dudit arbre, lesdites barrettes formant des plans de support pour des baguettes rigides disposées de part et d'autre de l'ouverture de sacs amovibles. According to an alternative embodiment, the bag support shaft comprises at least two pairs of transverse bars disposed on either side of said shaft, said bars forming support planes for rigid rods arranged on either side. opening of removable bags.
L'invention est en outre remarquable par les caractéristiques ci-après : - la barre de support des sacs fait avec l'horizontale un angle compris entre 5° et 10°; The invention is further distinguished by the following features: - the bag support bar made with the horizontal angle between 5 ° and 10 °;
- les montants du châssis sont disposés légèrement en oblique vers l'avant par rapport aux longerons inférieurs du châssis; - The amounts of the frame are arranged slightly obliquely forward with respect to the lower longitudinal members of the frame;
- l'extrémité avant des longerons du châssis porte un garde-corps vertical; - The front end of the frame rails carries a vertical railing;
- les longerons du châssis sont reliés entre eux par deux barres dirigées vers l'arrière qui se rejoignent sensiblement sur l'axe longitudinal médian du chariot; - The chassis members are interconnected by two bars directed towards the rear which meet substantially on the median longitudinal axis of the carriage;
- une roulette additionnelle est montée au point de rencontre des barres de liaison des longerons; - An additional wheel is mounted at the meeting point of the connecting bars of the side members;
- un plan de support additionnel est fixé en partie basse des montants du châssis. - An additional support plane is fixed at the bottom of the chassis uprights.
D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre d'exemples non limitatifs de réalisation de l'invention, en référence aux dessins annexés dans lesquels : Other characteristics and advantages of the invention will emerge from the following description of non-limiting examples of embodiment of the invention, with reference to the appended drawings in which:

Le chariot représenté sur la Figure 1 comporte un châssis constitué de longerons 1 auxquels sont fixées quatre roulettes 2a, 2b, qui peuvent être fixes ou directionnelles. Dans l'exemple représenté sur la figure 1 les roulettes arrière 2a sont fixes et les roulettes avant 2b sont directionnelles. Les roulettes sont montées à rotation dans des supports 2c et 2d fixés sous la partie horizontale du châssis. Les longerons 1 se raccordent à leur partie arrière à deux montants 3 sensiblement verticaux. Dans les exemples de réalisation représentés sur les figures, les montants 3 du châssis sont légèrement inclinés vers l'avant du chariot. De préférence cette inclinaison est de l'ordre de 12° par rapport à la verticale. The carriage shown in Figure 1 comprises a frame consisting of longitudinal members 1 which are fixed four wheels 2a, 2b, which can be fixed or directional. In the example shown in Figure 1 the rear rollers 2a are fixed and the front rollers 2b are directional. The casters are rotatably mounted in supports 2c and 2d fixed under the horizontal portion of the frame. The longitudinal members 1 are connected to their rear part to two uprights 3 substantially vertical. In the embodiments shown in the figures, the uprights 3 of the frame are slightly inclined towards the front of the carriage. Preferably this inclination is of the order of 12 ° relative to the vertical.
L'extrémité supérieure des montants 3 est recourbée vers l'arrière et forme avec une barre 4 un brancard de manœuvre. La barre de manœuvre 4 est de préférence gainée et porte en son centre un boîtier 5 destiné à recevoir divers équipements additionnels (consigneur, scanneur, écran d'affichage, interface interactive etc.). On voit sur les figures que les longerons 1 sont disposés l'un par rapport à l'autre avec conicité, c'est-à-dire que, dans le plan horizontal, leurs extrémités avant sont plus proches l'une de l'autre que leurs extrémités arrière. L'extrémité avant de chaque longeron 1 se raccorde une barre la dirigée vers l'arrière et le plan longitudinal médian du chariot. Les longerons 1 et les barres la sont raccordés par des coudes. La partie horizontale du châssis prend ainsi une forme générale en W qui procure un plan de support sur lequel il est possible de déposer des objets volumineux. De plus cet agencement assure lors de l'emboîtement entre deux chariots un guidage axial précoce qui facilite un coulis sèment sans heurt d'un chariot par rapport à l'autre (Figure 4). Deux entretoises lb renforcent la rigidité de cette partie du châssis et font fonction de butée d'emboîtement, évitant le coincement de deux chariots emboîtés l'un dans l'autre. The upper end of the uprights 3 is bent backwards and forms with a bar 4 a stretcher maneuver. The maneuvering bar 4 is preferably sheathed and carries at its center a housing 5 intended to receive various additional equipment (consigner, scanner, display screen, interactive interface, etc.). It can be seen in the figures that the longitudinal members 1 are arranged relative to each other with conicity, that is to say that, in the horizontal plane, their front ends are closer to one another as their rear ends. The front end of each spar 1 connects a bar facing the rear and the median longitudinal plane of the carriage. The longitudinal members 1 and the bars 1c are connected by elbows. The horizontal part of the frame thus takes a general shape in W which provides a support plane on which it is possible to deposit bulky objects. In addition, this arrangement ensures, during nesting between two carriages, an early axial guidance which facilitates smooth sliding of one carriage smoothly relative to the other (FIG. 4). Two struts lb reinforce the rigidity of this part of the frame and act as an interlocking abutment, avoiding the jamming of two trolleys nested one inside the other.
Sensiblement au niveau du brancard de manœuvre, les montants 3 du châssis sont reliés par deux traverses 6 et 7. Au centre de la traverse 6 est fixé un arbre 8 en forme de L dont la petite branche s'élève verticalement depuis son point de fixation sur la traverse 6 et la grande branche s'étend vers l'avant avec une légère inclinaison vers le haut jusqu'au plan vertical passant par les extrémités avant des longerons 1 du châssis. Au niveau de la jonction entre ses deux branches, l'arbre 8 repose sur la traverse 7, située immédiatement au-dessus de la traverse 6 sur lequel il est fixé. Ce point de support sur la traverse 7 légèrement décalé vers l'avant par rapport au plan vertical passant par la traverse 6 en raison de l'inclinaison des montants 3, assure une répartition sur l'ensemble du châssis des contraintes exercées sur l'arbre 8. Substantially at the maneuvering stretcher, the uprights 3 of the chassis are connected by two cross members 6 and 7. In the center of the crossbar 6 is fixed an L-shaped shaft 8 whose small branch rises vertically from its point of attachment. on the crossbar 6 and the large branch extends forward with a slight inclination upward to the vertical plane passing through the front ends of the frame members 1. At the junction between its two branches, the shaft 8 rests on the crossbar 7, located immediately above the crossbar 6 on which it is fixed. This support point on the crossbar 7 slightly offset forwardly relative to the vertical plane passing through the crossbar 6 due to the inclination of the uprights 3, ensures a distribution over the entire chassis of the stresses exerted on the shaft 8.
Comme indiqué précédemment, l'arbre 8 est muni de moyens pour l'accrochage de sacs amovibles 11 tels que ceux qui sont schématiquement représentés sur la Figure 3. Sur cette Figure, ces moyens d'accrochage sont constitués d'une part par des arceaux 9, disposés par paires à la partie supérieure de la barre 8, et d'autre part par des crochets 10 fixés au niveau de l'ouverture des sacs 11. En variante, au lieu des crochets 10, des bandes d'accrochage, d'une longueur adaptée à celle des arceaux 9 peuvent être fixées le long de l'ouverture des sacs 11. As indicated above, the shaft 8 is provided with means for attaching removable bags 11 such as those shown schematically in FIG. 3. In this FIGURE, these attachment means are constituted on the one hand by arches. 9, arranged in pairs at the upper part of the bar 8, and secondly by hooks 10 fixed at the opening of the bags 11. Alternatively, instead of the hooks 10, strips hooking, of a length adapted to that of the hoops 9 can be fixed along the opening of the bags 11.
Dans les exemples de réalisation représenté sur les Figures 3 et 8 on disposé quatre sacs amovibles de grande contenance, par exemple 50 litres environ chacun, de part et d'autre de la barre 8. Mais il est possible selon l'invention de disposer sur la barre 8 un plus grand nombre de sacs amovibles de contenances unitaires variées. In the exemplary embodiments shown in FIGS. 3 and 8, four removable bags of large capacity, for example approximately 50 liters each, are placed on either side of the bar 8. However, it is possible according to the invention to dispose of the bar 8 a larger number of removable bags of various unit capacities.
L'inclinaison vers le haut de l'arbre 8 est de l'ordre de 5° à 10°, de préférence 6°, par rapport à l'horizontale. The upward inclination of the shaft 8 is of the order of 5 ° to 10 °, preferably 6 °, relative to the horizontal.
L'inclinaison vers le haut de l'arbre 8, combinée à la conicité de la disposition mutuelle des longerons 1 permet l'emboîtabilité des chariots les uns dans les autres sans frottement ni coincement lorsque les sacs 11 sont enlevés. The upward inclination of the shaft 8, combined with the taper of the mutual arrangement of the longitudinal members 1 allows the nesting of the carriages within each other without friction or jamming when the bags 11 are removed.
L'arbre 8 peut-être monté fixe par rapport aux montants 3 du châssis. En variante, il peut être monté pivotant de manière à pouvoir débattre librement vers le haut lors de l'emboîtement, ce qui facilite encore cette opération. The shaft 8 can be fixedly mounted relative to the uprights 3 of the frame. Alternatively, it can be pivotally mounted so as to freely debate upward during nesting, which further facilitates this operation.
Dans ce cas, il est judicieux de disposer entre les montants 3, au dessus des traverses 6 et 7, une traverse additionnelle 12 qui a une double fonction : d'une part elle limite la possibilité de débattement de l'arbre vers le haut, ce qui limite le risque de vandalisme, d'autre part, cette traverse additionnelle sert de chevalet pour le montage sur le chariot d'accessoires tel qu'un siège pour bébés, un panier additionnel ou autres. In this case, it is advisable to have between the uprights 3, above the crosspieces 6 and 7, an additional cross member 12 which has a dual function: on the one hand it limits the possibility of movement of the shaft upwards, which limits the risk of vandalism, on the other hand, this additional cross serves as an easel for mounting on the trolley accessories such as a baby seat, an additional basket or others.
On voit également sur les Figures 2 et 3 qu'un plan de support additionnel 15 est fixé entre les montants 3. Dans cet exemple il est formé par une grille horizontale qui s'étend vers l'arrière sous le brancard de manœuvre. Elle est destinée à recevoir des objets volumineux et lourds tels que des paquets de bouteilles, des barils de lessives ou autres qui sont généralement conditionnés avec des poignées et ne nécessitent pas l'utilisation d'un sac .FIGS. 2 and 3 also show that an additional support plane 15 is fixed between the uprights 3. In this example it is formed by a horizontal grid which extends rearwardly under the maneuvering stretcher. It is intended to receive bulky and heavy objects such as packs of bottles, barrels of laundry or other that are generally packaged with handles and do not require the use of a bag.
La Figure 5 illustre une variante avantageuse de réalisation de l'invention. On y voit que, à proximité du point de jonction des barres la de liaison des longerons 1 on a monté une cinquième roulette 16. Cette roulette additionnelle, améliore la maniabilité en courbe du chariot lorsqu'il est chargé, rendant ainsi son maniement plus confortable pour l'usager. Figure 5 illustrates an advantageous variant embodiment of the invention. It will be seen that, near the junction point of the connecting bars of the longitudinal members 1, a fifth wheel 16 has been mounted. This additional wheel, improves the curl maneuverability of the truck when loaded, thus making its handling more comfortable. for the user.
La Figure 6 illustre une autre variante avantageuse de réalisation de l'invention. On voit qu'à l'extrémité avant des longerons 1, on a disposé un garde-corps 17, formé par un arceau qui s'étend en hauteur jusqu'au niveau du milieu des montants 3. Figure 6 illustrates another advantageous variant embodiment of the invention. It can be seen that at the front end of the longitudinal members 1, there is a railing 17 formed by a hoop which extends in height up to the middle level of the uprights 3.
Les Figures 7 et 8 illustrent un mode alternatif des moyens d'accrochage des sacs 11 sur la barre 8 dans lequel l'arbre 8 comporte au moins deux paires de barrettes transversales 13 disposées de part et d'autre dudit arbre, lesdites barrettes formant des plans de support pour des baguettes rigides disposées de part et d'autre de l'ouverture des sacs amovibles 11. Dans les exemples illustrés sur les figures 7 et 8, les barrettes transversales 13 sont au nombre de six et délimitent avec la barre 8 quatre alvéoles ouvertes pour la réception de quatre sacs amovibles. Comme indiqué précédemment, il est possible selon l'invention de disposer sur la barre 8 un plus grand nombre d'alvéoles pour des sacs amovibles de contenances unitaires variées. FIGS. 7 and 8 illustrate an alternative mode of the attachment means of the bags 11 on the bar 8 in which the shaft 8 comprises at least two pairs of transverse bars 13 arranged on either side of said shaft, said bars forming support planes for rigid rods arranged on either side of the opening of the removable bags 11. In the examples illustrated in FIGS. 7 and 8, the transverse bars 13 are six in number and delimit with the bar 8 four open cells for the reception of four removable bags. As indicated above, it is possible according to the invention to have on the bar 8 a larger number of cells for removable bags of different unit capacities.
Selon une forme de réalisation alternative, non représentée, les alvéoles formées par la combinaison des barrettes avec la barre de support peuvent être fermées grâce à des barrettes additionnelles disposées parallèlement à la barre de support aux extrémités libres des barrettes. Selon encore une autre forme alternative de réalisation alternative, non représentée, la grande branche du L formant la barre 8 peut être remplacée par un cadre entre les bords duquel des sacs 11 peuvent être suspendus. According to an alternative embodiment, not shown, the cells formed by the combination of the bars with the support bar can be closed by means of additional strips arranged parallel to the support bar at the free ends of the bars. According to yet another alternative form of alternative embodiment, not shown, the large branch of the L forming the bar 8 can be replaced by a frame between the edges of which bags 11 can be suspended.
