Description
Chariot et procédé de distribution de repas
La présente invention concerne les chariots et notamment les chariots de distribution de repas1 ainsi que les procédés de distribution de repas.Cart and method of distributing meals
The present invention relates to carts and in particular meal distribution carts1 as well as meal distribution methods.
Au brevet des Etats-Unis d'Amérique n" 3 872 686, on décrit déjà la combinaison d'un chariot et d'une borne de réfrigération qui peuvent être accouplés. Pour servir des mets chauds, il faut en sortir les plats du chariot et les chauffer dans un four micrnonde. U.S. Patent No. 3,872,686 already describes the combination of a cart and a refrigeration terminal that can be mated. To serve hot food, the dishes must be taken out of the cart and heat them in a microwave oven.
La demande de brevet français n" 9115109 y remédie en prévoyant un chariot pouvant être accouplé à une borne de réfrigération et de chauffage. Le chariot est ainsi allégé, peu encombrant et facilement nettoyable au jet d'eau sous pression. French patent application No. 9115109 remedies this by providing a trolley which can be coupled to a cooling and heating terminal. The trolley is thus lightened, compact and easily cleanable with a pressurized water jet.
Mais on s'est maintenant rendu compte que la solution proposée à ce dernier document a plusieurs inconvénients. La borne, qui comporte une soufflerie d'air froid et une soufflerie d'air chaud, est bruyante. Comme elle est lourde, elle est souvent montée à poste fixe. Le bruit permanent qu'elle engendre toujours au même endroit peut être très gênant, notamment dans un hôpital. La borne représente un point chaud fixe qui élève localement la température de l'endroit où elle se trouve. Cela aussi peut être très coûteux lorsque les locaux sont ventilés ou conditionnés. Mais, surtout, la borne chaude et notamment la partie de la borne qui transmet la chaleur au chariot lorsqu'ils sont accouplés, représente, lorsqu'ils viennent d'être désaccouplés, un grave danger de brûlure et cela d'autant plus que la borne, à la différence du chariot, n'est pas alors sous la surveillance d'une opératrice. But we have now realized that the solution proposed to this last document has several drawbacks. The terminal, which has a cold air blower and a hot air blower, is noisy. As it is heavy, it is often mounted in a fixed position. The permanent noise it always generates in the same place can be very annoying, especially in a hospital. The terminal represents a fixed hot spot which locally raises the temperature of the place where it is located. This too can be very expensive when the premises are ventilated or conditioned. But, above all, the hot bollard and in particular the part of the bollard which transmits heat to the carriage when they are coupled, represents, when they have just been uncoupled, a serious danger of burns and this all the more so since the Unlike the carriage, the terminal is not then under the supervision of an operator.
L'invention pallie ces inconvénients par un chariot et un ensemble d'un chariot et d'une borne qui, tout en permettant de servir des plateaux repas1 comportant à la fois des mets chauds et des mets froids en lieu et temps requis, n'entraîne pas de danger de brûlure et est moins bruyant. The invention overcomes these drawbacks by a trolley and a set of a trolley and a terminal which, while making it possible to serve meal trays1 comprising both hot and cold dishes in the place and time required, n ' no danger of burns and is less noisy.
Dans le chariot suivant l'invention, dont la caisse comprend des moyens de définition d'un espace froid, d'une part1 et, d'autre part, d'un espace chaud, il est prévu des moyens d'accouplement, tant de l'espace froid que de l'espace chaud, à une borne de production de frigories qui n'est pas embarquée sur le chariot de manière à les refroidir, tandis que l'espace chaud est chauffé par des moyens de chauffage qui sont embarqués sur le chariot. In the carriage according to the invention, the body of which comprises means for defining a cold space, on the one hand1 and, on the other hand, a hot space, there are provided coupling means, both the cold space than the hot space, to a frigory production terminal which is not on board the carriage so as to cool them, while the hot space is heated by heating means which are on board carriage.
Comme les moyens de chauffage sont embarqués sur le chariot, ils ne créent pas de points chauds dangereux, au contact desquels on peut se brûler, ni non plus des points chauds fixes, puisque le chariot est destiné à se mouvoir. Certes, le chariot est un peu plus lourd qu'auparavant, mais il reste encore d'un poids acceptable pour pouvoir être poussé sans difficulté, tandis que la borne est considérablement allégée, puisqu'elle ne comporte plus qu'un dispositif de production de frigories et non des moyens de chauffage, en sorte qu'elle peut être elle aussi prévue mobile. As the heating means are on board the trolley, they do not create dangerous hot spots, in contact with which one can get burned, nor either fixed hot spots, since the trolley is intended to move. Admittedly, the trolley is a little heavier than before, but it still remains of an acceptable weight to be able to be pushed without difficulty, while the terminal is considerably lightened, since it only comprises a device for producing frigories and not heating means, so that it can also be provided mobile.
Suivant un mode de réalisation nécessitant particulièrement peu de pièces, le chariot a une porte munie d'un loquet coopérant avec un mentonnet prévu sur la caisse et la borne a un autre loquet identique au premier et apte à coopérer avec le mentonnet. C'est donc un même mentonnet qui sert suivant le loquet utilisé à fermer la porte ou accoupler le chariot et la bome. According to an embodiment requiring particularly few parts, the carriage has a door provided with a latch cooperating with a chin provided on the body and the terminal has another latch identical to the first and able to cooperate with the chin. It is therefore the same bar which is used according to the latch used to close the door or couple the carriage and the boom.
De préférence, les moyens de chauffage sont des moyens ayant de l'inertie calorifique. Ce peut être notamment des plaques chauffantes à résistance électrique. Preferably, the heating means are means having calorific inertia. These may in particular be electric resistance heating plates.
L'invention vise également un procédé de distribution de repas qui consiste successivement:
- à préparer en un premier lieu un plateau-repas comportant une zone pour mets chauds et une zone pour mets froids à une première température froide et à mettre ce plateau-repas dans un chariot suivant l'invention,
- à transporter le chariot en un deuxième lieu où se trouve une borne de production de frigories et à accoupler le chariot à la borne,
- à un instant donné, précédent d'une première durée donnée le moment où le repas doit être consommé, à mettre en action les moyens de chauffage de l'espace chaud et,
- à un instant, précédent d'une seconde durée, inférieure à la première1 le moment où le repas doit être consommé, à désaccoupler le chariot de la borne et à l'amener en un troisième lieu où doit avoir lieu la consommation du repas.The invention also relates to a method of distributing meals which successively consists of:
in the first place, preparing a meal tray comprising a zone for hot food and a zone for cold food at a first cold temperature and placing this meal tray in a trolley according to the invention,
- transport the trolley to a second place where there is a cold production terminal and couple the trolley to the terminal,
- at a given instant, preceding a first given duration when the meal is to be consumed, to activate the means for heating the hot space and,
- at an instant, preceding by a second duration, less than the first1 the moment when the meal must be consumed, uncoupling the carriage from the terminal and bringing it to a third place where the consumption of the meal must take place.
Pendant que l'on transporte le chariot du deuxième lieu au troisième lieu, les moyens de chauffage continuent, en raison de leur inertie calorifique, à chauffer les mets chauds, en sorte que ceux-ci sont portés à la température requise pendant la durée requise cependant que les opérateurs gagnent du temps, puisqu'ils peuvent désaccoupler le chariot de la borne avant que les moyens de chauffage aient chauffé complètement les mets chauds pendant la première durée requise. While transporting the trolley from the second place to the third place, the heating means continue, because of their calorific inertia, to heat the hot dishes, so that they are brought to the required temperature for the required time however, operators save time, since they can uncouple the trolley from the terminal before the heating means have completely heated the hot food for the first required time.
Au dessin annexé, donné uniquement à titre d'exemple:
la figure 1 est une vue d'un chariot sur le point d'être accouplé à une borne, et la figure 2 est une vue en perspective de la borne.In the attached drawing, given solely by way of example:
Figure 1 is a view of a carriage about to be coupled to a terminal, and Figure 2 is a perspective view of the terminal.
L'ensemble suivant l'invention se compose d'un chariot et d'une borne. The assembly according to the invention consists of a carriage and a terminal.
Le chariot est constitué d'une caisse 1 parallélépipédique montée sur un socle 2 muni de roulettes 3. Deux faces opposées de la caisse 1 sont ouvertes et munies chacune d'une porte 4. Chaque porte est munie d'un loquet 5 coopérant avec un mentonnet 6 prévu sur la caisse 1. The carriage consists of a rectangular box 1 mounted on a base 2 provided with rollers 3. Two opposite faces of the box 1 are open and each provided with a door 4. Each door is provided with a latch 5 cooperating with a chin 6 provided on the body 1.
A l'intérieur de la caisse 1 sont prévues des glissières 7 horizontales destinées à recevoir des plateaux 8. En-dessous de chaque plateau 8 est prévue une plaque 9 chauffante par résistance électrique reliée par un circuit et par un dispositif 10 de commande à une prise 11 électrique. Inside the box 1 are provided horizontal runners 7 intended to receive plates 8. Below each plate 8 is provided a plate 9 heating by electrical resistance connected by a circuit and by a device 10 for controlling a electrical outlet 11.
Des cloches 12 recouvrent les alvéoles de réception des mets chauds qui se trouvent au-dessus des plaques chauffantes 9, celles-ci ne s'étendant que sur la moitié des plateaux 8, de manière à définir un espace chaud audessus d'elles, tandis que l'espace qui se trouve à côté d'elles est un espace froid. Bells 12 cover the cells for receiving hot food which are located above the hot plates 9, these extending only over half of the trays 8, so as to define a hot space above them, while that the space next to them is a cold space.
La borne comporte une caisse 21 ménageant une cavité 22 qui reçoit un évaporateur frigorifique 23 avec un ventilateur 24 protégé par une grille perforée 25. Cet évaporateur est alimenté par un groupe compresseur 26 au moyen d'un câble 27 électrique. Un crochet 28 ainsi qu'un loquet 29 en tout point semblable au loquet 5 permet, lorsque la porte 4 est ouverte, d'accoupler la borne au chariot en sorte que l'évaporateur 23 envoie de l'air froid dans le chariot et en refroidit le contenu. La borne est montée sur roulettes 30. The terminal includes a box 21 providing a cavity 22 which receives a refrigeration evaporator 23 with a fan 24 protected by a perforated grid 25. This evaporator is supplied by a compressor unit 26 by means of an electric cable 27. A hook 28 as well as a latch 29 at any point similar to the latch 5 makes it possible, when the door 4 is open, to couple the terminal to the carriage so that the evaporator 23 sends cold air into the carriage and cools the contents. The bollard is mounted on casters 30.
Lorsque le chariot est accouplé à la borne le ventilateur 24 envoie de l'air froid dans le chariot et en refroidit le contenu se trouvant tant dans l'espace chaud que dans l'espace froid. When the carriage is coupled to the terminal, the fan 24 sends cold air into the carriage and cools the content thereof, both in the hot space and in the cold space.
Suivant une variante du chariot, une cloison thermiquement isolante sépare l'espace froid de l'espace chaud. According to a variant of the cart, a thermally insulating partition separates the cold space from the hot space.
Quand le chariot est désaccouplé de la borne et quand les moyens de chauffage 9 entrent en action, L'espace chaud est chauffé, tandis que l'espace froid conserve sensiblement sa température. When the carriage is uncoupled from the terminal and when the heating means 9 come into action, the hot space is heated, while the cold space substantially retains its temperature.
