  Chariot orientable, prolongé ou non par une"trottinette" La présente invention concerne un chariot permettant de faire des courses dans les magasins ou les grandes surfaces, que l'on pourrait pousser devant soi, qui serait orientable et qui pourrait être prolongé par   une"trottinette".   



  Lorsqu'on fait des achats, le problème majeur est de ramener les marchandises chez soi, si possible sans avoir à les porter. Actuellement, même si on habite à proximité d'une grande surface, les seules solutions possibles sont de prendre sa voiture ou d'utiliser un caddie que l'on tire à côté de soi. Une alternative possible serait l'utilisation d'un chariot orientable grâce à un guidon, à 2,3 ou 4 roues supportant un châssis sur lequel serait fixé un bac amovible, prolongé ou non par une planchette supportée par une roue,   dénommée"trottinette",   repliable contre le guidon et amovible, ou, par une trottinette qui se fixerait à un chariot. 



  Ce chariot présenterait de nombreux avantages par rapport aux caddies tirés à côté de soi, par rapport au vélos et même, par rapport aux voitures : 1) Par rapport aux caddies tirés : - dans le cas où le chariot serait muni de 3 ou 4 roues, la contenance du bac destiné à recevoir les marchandises serait plus grande que celle d'un sac de caddie tiré à côté de soi et permettrait par conséquent d'acheter une plus grande quantité d'articles. Une surface plus importante à la base du bac du chariot éviterait l'écrasement des marchandises les unes par les autres. 



    - un   chariot à 3 ou 4 roues aurait une meilleure stabilité et pourrait servir d'appui à la marche pour les personnes âgées. 



  - les roues pourraient avoir un diamètre plus grand et avoir des pneus plus larges et gonflables, permettant de monter plus aisément sur les trottoirs et de rouler confortablement sur ceux constitués de pavés. 



  - l'ajout d'un levier à l'arrière du chariot faciliterait la montée sur les trottoirs ; le guidon quant à lui pourrait être tiré vers soi de manière à soulever l'avant du chariot tout en conservant la portée de la charge par les roues arrière du chariot, chose impossible avec un caddie tiré qui doit être soulevé ; le guidon permettrait bien sûr également d'orienter l'ensemble en le poussant. 

 <Desc/Clms Page number 2> 

 



  - le bac du chariot pourrait être conçu de manière à pouvoir supporter un enfant en bas âge et permettrait d'éviter d'utiliser une poussette d'enfant en plus d'un caddie. 



  - l'utilisation de ce chariot permettrait de ne pas utiliser les caddies mis à la disposition des clients dans les grandes surfaces, ce qui diminuerait leurs frais d'achats et d'entretiens. 



    - la   prolongation du chariot par une"trottinette", ou inversement, permettrait une rapidité de déplacement supérieure et réduirait la durée des courses. 



  - l'ajout de feux avant et arrière ainsi que de freins permettrait l'utilisation du chariot sur la chaussée. On peut imaginer l'adjonction de bandes autocollantes fluorescentes ou phosphorescentes, ou même d'un bac phosphorescent lui conférant une luminescence pendant un temps assez long, la nuit tombante, à l'heure où tous les chats sont gris. 



  2) Par rapport aux vélos : - les marchandises seraient moins écrasées les unes par les autres qu'à l'intérieur des sacs conçus pour les vélos. 



    - le   fait de garder le chariot avec soi pendant les courses évite les risques de vol du vélo et/ou des sacs du vélo et évite de devoir l'enchaîner à un support. 



    - le   chariot ne doit pas être fixé à un support pour tenir debout. 



    - la   légèreté et la compacité de l'ensemble permettrait la montée dans les trams, bus, métros et trains. 



    - le   guidon du chariot pourrait être pliable, le bac amovible et la "trottinette"pliable et/ou amovible, rendant l'ensemble peu encombrant. 



    3) Par rapport voitures :     - le   caractère économique et non polluant du chariot est également à souligner ; il constituerait une solution pour les personnes à faibles revenus ou pour les personnes âgées ne se sentant plus capables de conduire une voiture. 



    - l'usage   du chariot désengorgerait les parkings des grandes surfaces et éviterait à l'utilisateur d'être obligé d'attendre qu'une place se libère. Cela éviterait également   de"devoir"décharger   la voiture en double file et d'ensuite à nouveau chercher une place pour se garer à proximité de son lieu d'habitation. 



    - le   chariot dont le bac serait amovible pourrait servir au transport de valises par exemple et contribuer ainsi à éviter l'usage quasi obligatoire d'une voiture pour voyager.

  The present invention relates to a trolley for shopping in stores or large surfaces, which could be pushed in front of you, which would be orientable and which could be extended by a " scooter".



  When shopping, the major problem is to bring the goods home, if possible without having to carry them. Currently, even if you live near a large area, the only possible solutions are to take your car or use a shopping cart that you pull next to you. A possible alternative would be the use of an adjustable trolley thanks to a handlebar, with 2,3 or 4 wheels supporting a chassis on which would be fixed a removable tray, extended or not by a board supported by a wheel, called "scooter" , foldable against the handlebar and removable, or, by a scooter which would be fixed to a trolley.



  This trolley would have many advantages compared to shopping carts pulled next to you, compared to bicycles and even, compared to cars: 1) Compared to drawn shopping carts: - in the case where the trolley would have 3 or 4 wheels , the capacity of the bin intended to receive the goods would be greater than that of a shopping trolley bag pulled next to you and would therefore make it possible to buy a larger quantity of articles. A larger surface at the base of the trolley tray would prevent the goods from being crushed by each other.



    - a trolley with 3 or 4 wheels would have better stability and could serve as a walking aid for the elderly.



  - the wheels could have a larger diameter and have wider and inflatable tires, making it easier to climb on the sidewalks and to roll comfortably on those made up of paving stones.



  - the addition of a lever at the rear of the carriage would facilitate climbing on the sidewalks; the handlebars could be pulled towards you so as to lift the front of the truck while retaining the reach of the load by the rear wheels of the truck, something impossible with a drawn shopping cart which must be lifted; the handlebars would of course also guide the assembly by pushing it.

 <Desc / Clms Page number 2>

 



  - the trolley bin could be designed so as to be able to support an infant and would avoid using a child's stroller in addition to a shopping cart.



  - the use of this trolley would make it possible not to use the shopping carts made available to customers in supermarkets, which would reduce their purchase and maintenance costs.



    - the extension of the trolley by a "scooter", or vice versa, would allow a higher speed of movement and would reduce the duration of the races.



  - the addition of front and rear lights as well as brakes would allow the use of the truck on the road. One can imagine the addition of fluorescent or phosphorescent self-adhesive strips, or even a phosphorescent tray giving it luminescence for a fairly long time, at nightfall, at a time when all cats are gray.



  2) Compared to bikes: - the goods would be less crushed by each other than inside the bags designed for bikes.



    - keeping the trolley with you during the races avoids the risk of theft of the bicycle and / or bicycle bags and avoids having to chain it to a support.



    - the trolley must not be fixed to a support to stand upright.



    - the lightness and compactness of the whole would allow the rise in trams, buses, metros and trains.



    - The handlebar of the cart could be foldable, the removable tray and the "scooter" foldable and / or removable, making the whole space-saving.



    3) In relation to cars: - the economical and non-polluting nature of the truck is also to be emphasized; it would be a solution for people on low incomes or for the elderly who no longer feel able to drive a car.



    - the use of the trolley would unclog the car parks of large areas and avoid the user having to wait for a space to become available. This would also avoid "having" to unload the car in double file and then again look for a place to park near his place of residence.



    - the trolley whose tray would be removable could be used for the transport of suitcases for example and thus help to avoid the almost compulsory use of a car for traveling.

The side walls (28a, 28b, 28c, 28d) of the plastic tray can be raised by sliding the flaps (29a, 29b, 29c and 29d) serving as cover for the tray in vertical gutters (30a, 30b, 30c, 30d , 30th, 30f, 30g, 30h). Small flaps (33a and 33b) protect the contents of the bin from the rain and can be used to support a hook-and-loop closure of the "dual lock" type.

(*) The correct length of the board (9) drawn is 8 cm at a 1/20 scale.
