Abstract

The carriage 1 has a perforated container 4, capable of containing dry ice. The container 4 is open at its top end and, by the displacement of the carriage, it can be placed under a hood 7, connected to the output of a dry ice gun, carried by a gantry 8 under which the carriage can be placed.

Description

La présente invention est relative à des moyens permettant la distribution des repas. The present invention relates to means for distributing meals.

Les moyens permettant la distribution des repas dans les collectivités sont généralement constitués par un chariot comportant deux compartiments dont l'un est destiné aux aliments à consommer chauds et l'autre à ceux à consommer froids. The means allowing the distribution of meals in communities are generally constituted by a trolley comprising two compartments, one of which is intended for food to be consumed hot and the other for that to be consumed cold.

Généralement, les chariots sont chargés plusieurs heures avant la distribution des repas qui sont réchauffés sur le lieu de distribution. Cependant, la législation actuelle exige que les repas soient stockés, avant réchauffage à une température basse de l'ordre de 3"C.  Generally, the carts are loaded several hours before the distribution of meals which are reheated at the distribution site. However, current legislation requires that meals be stored before reheating at a low temperature of around 3 "C.

A cet effet, on a imaginé des dispositifs tels que celui décrit dans la demande de brevet français N" 78 33I89 déposée le 24 Novembre I978, dans lesquels les chariots à compartiments isothermes pouvaient être reliés à la sortie d'un générateur d'air froid disposé dans ou à proximité du local de distribution. To this end, devices such as that described in French patent application No. 78 33I89 filed on November 24, 1978 have been devised, in which the trolleys with isothermal compartments could be connected to the outlet of a cold air generator. located in or near the distribution room.

Ce procédé de réfrigération permet de réaliser des chariots légers mais il est relativement coûteux et astreignant puisque chaque salle doit comporter une installation de production d'air froid, avec tous les inconvénients que cela présente. This refrigeration process makes it possible to produce light trolleys but it is relatively expensive and demanding since each room must include a cold air production installation, with all the disadvantages that this presents.

Selon la présente' invention, chaque chariot isot,herme présente un bac susceptible de recevoir de la neige carbonique. According to the present invention, each isot, herm trolley has a bin capable of receiving dry ice.

Selon un mode de réalisation, le bac du chariot, qui est ouvert à sa partie supérieure, est placé sous un portique comportant à sa partie supérieure une hotte de déversement'de la neige carbonique. According to one embodiment, the trolley tray, which is open at its upper part, is placed under a gantry comprising at its upper part a hood for discharging carbon dioxide snow.

L'invention sera mieux comprise par la description qui va suivre, faite en se référant au dessin annexé à titre d'exemple indicatif seulement,sur lequel:
La figure 1 est une vue en perspective montrant le chariot de l'invention avant son passage sous le portique;
La figure 2 est une vue analogue à la figure 1 montrant le chariot, en cours de remplissage, sous le portique;
La figure 3 est une vue partielle en perspective montrant un détail de réalisation;
Les figures 4,5 et 6 sont des vues très schématiques en coupe illustrant différents modes de réalisation du chariot.The invention will be better understood from the description which follows, made with reference to the accompanying drawing by way of indicative example only, in which:
Figure 1 is a perspective view showing the carriage of the invention before its passage under the gantry;
Figure 2 is a view similar to Figure 1 showing the carriage, being filled, under the gantry;
Figure 3 is a partial perspective view showing a detail of embodiment;
Figures 4,5 and 6 are very schematic sectional views illustrating different embodiments of the carriage.

En se reportant au dessin, on voit que 1 est un chariot isotherme comportant par exemple deux compatiments auxquels on accède par deux portes 2 et 3. Referring to the drawing, it can be seen that 1 is an insulated carriage comprising, for example, two compartments which are accessed by two doors 2 and 3.

Selon l'inven'ion, les deux compartiments du chariot sont séparés par un bac 4 perforé normalement obturé à sa partie supérieure par un couvercle 5, isotherme. According to the invention, the two compartments of the carriage are separated by a perforated tray 4 normally closed at its upper part by a cover 5, isothermal.

Après avoir chargé le chariot, on remplit le bac 4 à l'aide de neige carbonique délivrée par un canon à neige dont l'orifice de sortie est raccordé à une hotte 7 située à la partie supérieure d'un portique 8 sous lequel le chariot est placé. La hotte 7 présente une canalisation 9 d'aspiration du gaz carbonique qui se dégage durant le remplissage du bac. After having loaded the trolley, the tank 4 is filled with carbon dioxide snow delivered by a snow cannon whose outlet orifice is connected to a hood 7 located at the top of a gantry 8 under which the trolley is placed. The hood 7 has a suction line 9 for carbon dioxide which is released during the filling of the tank.

Selon un mode de réalisation, l'un des pieds du portique 8 présente une butée escamotable 10 pourvue d'un contacteur (non représenté) de commande de l'ouverture de la vanne du canon à neige. De préférence, cette électrovanne est temporisée. According to one embodiment, one of the legs of the gantry 8 has a retractable stop 10 provided with a contactor (not shown) for controlling the opening of the valve of the snow cannon. Preferably, this solenoid valve is timed.

Lorsque le bac 4 est plein, le manutentionnaire fait basculer la-butée 10, à l'aide d'une pédale 11, pour dégager le chariot. When the tray 4 is full, the handler switches the stop 10, using a pedal 11, to release the carriage.

Naturellement et comme montré sur les figures 5 à 7, le bac 4 peut être disposé de diverses façons à l'intérieur du,chariot 1 qui peut même comporter plusieurs bacs.  Naturally and as shown in Figures 5 to 7, the tray 4 can be arranged in various ways inside the carriage 1 which can even have several trays.
