DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a trolley designed for use as a conveying trolley for conveying products, in particular foods and drinks for sale, comprising a frame provided with wheels and carrying one or more containers.
Such a trolley is known from U.S. Pat. No. 4,076,349. Said trolley comprises a frame provided with castors, and having a rectangular unitary cabinet structure. On top of the cabinet a plurality of liquid dispensing units are mounted, accessible for service from both front and rear sides. Hot drinks are contained in containers on top of the trolley and are prepared in advance, whereas the cold drinks are fed from the inside of the trolley by means of CO.sub.2 -pressure. Further a fixed ice chamber is present. No provisions are made for containing and distributing hot foods. This known trolley has a number of disadvantages. In the first place, it is relatively unstable, as rather large quantities of hot beverages are present in containers on top of the trolley and no provisions are made for containing hot foods. The hot drinks are prepared in advance and carried in insulated containers, which means a limited distribution time. Coffee in particular relatively soon acquires an unpleasant taste. Finally, the number of the drinks which can be carried on such a known trolley is very limited, since the dimensions of the trolley cannot be great due to the requirements in use.
Said trolley is used for selling or distributing beverages at conventions, conferences, meetings and similar occasions. The purposes thereof is to be able to serve a large number of beverages in a very limited time. The object of the present invention is to eliminate the abovementioned disadvantages and to provide a generally improved trolley for conveying products, in particular food and drinks for sale. To that end the invention is characterized in that the containers (A-D) are or can be placed one above the other in the frame, the frame in the bottom thereof having a fixed water supply container with insulation and heating means. A pump with battery supply is also present for conveying the water heated in said container to one or more tap points, and the containers (A-D) are selected from: the fixed water supply container, and which may or may not be provided with heating means; and
The invention provides a trolley in which hot foods can be kept hot by using heating means and cold foods or drinks can be kept cold for a long time, and the hot drinks and liquid foods can in each case be prepared fresh from hot water and an extract. The trolley according to the invention is also extremely stable, in particular as the fixed water supply is situated in the bottom thereof. This water supply has generally already been brought to a temperature which is suitable for making coffee, tea, soup or the like. Since the drinks are prepared at the place of sale, excellent quality thereof can always be ensured.
The heating means are preferably exchangeable. This makes it possible to select whether or not to make a container carry out a heating function, with the result that the layout of the trolley or the function of the containers in use can be varied as desired.
The cooling container advantageously also comprises exchangeable cooling means which can be designed, for example, in the form of cooling elements to be placed in the cooling container or a cooling mechanism to be connected to the cooling container, supplied by, for example, a battery or a fossil fuel.
One or more of the containers are also advantageously exchangeable, which means that for replenishment thereof the particular containers in the trolley itself do not have to be cleaned and refilled. Instead, while the trolley is in a filling center, the containers can be removed from the trolley in their entirety, including their heating or cooling means, and filled containers can be placed therein. The layout of the trolley can also be varied as desired as regards the containers. For example, an additional hot water container, possibly having its own heatin
