Definitions

  • the invention relates to a component for producing a cuboid housing made of plastic for a serving trolley, in particular a serving trolley for aircraft.
  • housings and container parts in a suitable tool, e.g. to be made from plastics such as polystyrene or polyurethane using the foaming technique or the spray technique. Furniture and device parts, as well as housings for serving trolleys, are manufactured in a mold using injection molding machines. The costs of the molding tools play a not inconsiderable effort. If several sizes of one device type are to be manufactured, corresponding different molding tools must be available.
  • US-A-3905 668 shows a component for producing a cuboid housing, which comprises half the housing cover, half the housing base, half of the two side walls and a complete end wall.
  • thermoplastic plastic described in DE-B-1055 802 is not suitable for large components, such as the housing of a serving trolley.
  • the invention has for its object to manufacture the container for a serving trolley, in particular a serving trolley for airplanes - from plastic with little outlay on tooling costs and yet to maintain the required strength.
  • the housing consists of two identical shell parts, whereby the uniform shell part is designed so that on the one hand it can be connected to a body with the same shell part, but on the other hand it is also possible to halve one shell part and the two parts obtained into one Join the half-size body.
  • the necessary strength of the connection is made possible by the fact that the large areas to be joined together have a profiling which, on one half of the shell, is negatively counter to the profiling of the other halves of the shell.
  • the housing 1 consists of the side wall 1, half the housing cover 2 and half the housing base 3. In addition, half partitions for the upper drawer 4 and a central stiffening wall 5th be provided.
  • the housing cover 2 is provided with a raised peripheral edge 6, so that a secure storage space is created. Lateral support and guide strips 7 for trays to be inserted as well as cooling channels 8 for the cooling gas flowing out of the upper cooling compartment are formed in the side wall 1.
  • Such a component, which forms a housing half is made of a thermoplastic with very high impact strength according to the so-called TSG process. In this special process, the thermoplastic material to be sprayed is additionally mixed with a blowing agent for better mold filling and surface quality.
  • the plastic is completely colored with the desired color. This creates a practically indestructible container even in rough use, which still has its external appearance even after a long time.
  • Two such shell parts produced in the same molding tool are permanently bonded to one another to form a heavy-duty housing by appropriately designing the connection points by joining them in mirror image.
  • 3a and 3b show this in two examples in which the ceiling area is designed differently.
  • An identical part b is added to part a in mirror image.
  • the gluing point of the abutting transverse walls can be formed according to FIG. 2.
  • the Z-shaped profile ensures that the two shell parts fit together precisely because their tips slide into a counter-groove.
  • the component according to the invention is also symmetrically divided into two equal halves in relation to a central plane E (indicated by a line) that runs through the housing cover, side wall and housing base. If the shell part is separated along this plane, two parts are obtained which can likewise be joined together to form a housing, albeit of half the size, as illustrated in FIG. 4. The later separation can be facilitated by inserting strips in the area of the separation point for the molding tool.
  • connection points (Fig. 2) is formed on one half of the shell part negatively congruent to the profile of the other half of the shell part so that the shell parts, be it the whole or the halved shell parts can be put together in mirror image.
  • the side cooling gas channels 8 starting from the upper cooling compartment are arranged in the interior of the side wall 1 such that after the separation of the shell divider at least one cooling gas channel 8 remains at both ends of the shell part halves, as indicated in FIG. 1.
