Patents Assigned to Wolf-Dietrich Hannecke Kunststofftechnik
  • Patent number: 6763771
    Abstract: The disclosure relates to a method for producing one-piece, three-dimensional shaped bodies, shaped bodies produced according to the method, and a device for carrying out the method. The aim is to simplify the production of one-piece, three-dimensional shaped bodies which can be easily produced. To these ends, the disclosure provides that a plate which is resistant to bending at room temperature is heated only in heating regions along deformation lines, especially bending lines, and is subsequently deformed freely in space, i.e. without the use of a stop edge, indentation, template or die, whereby the attained three-dimensional shape is permanently preserved after cooling during which the material blank is kept.

  • Patent number: 6698599
    Abstract: A device for displaying flat and flexible objects. The device displays flat and flexible objects and is specially suitable for modular display systems, e.g. display racks or display consoles. Flat and specially non-rigid display goods are held upright, and can be reliably inserted and withdrawn. The bottom, the rear wall and the sidewalls are configured as a single-pieced plastic injection molded part. At least one of the sidewalls is flexibly configured at least in one of its segments as a clamp holding the inserted objects in an upright position.

  • Patent number: 5123544
    Abstract: An arrangement for displaying flat bendable objects, especially sheet shaped record carriers comprises a horizontal bottom plate, at least two upwardly open elongated compartments for receiving of objects, two substantially vertical curved side walls extending so that they approach one another to define in the compartments two withdrawal openings located near one another at an outer edge of the bottom plate. The side walls have longitudinal portions which together form a one piece wall portion. The side walls also have rear extensions which extend rearwardly of the wall portion and form inner side walls. The inner side walls are turnable about axes extending perpendicularly to the bottom plate and are spring loaded in direction toward the compartments.
