  • Patent number: 11338486
    Abstract: An injection-moulding tool (2) for producing an in particular thin-walled plastics component, comprising: —at least two tool elements (1, 1?, 1?), wherein the at least two tool elements (1, 1?, 1?), in a closed position of the injection-moulding tool (2), are moved against one another at least in sections so as to form at least a subregion of a shape-imparting tool cavity (3) of the injection-moulding tool (2), wherein—the at least two tool elements (1, 1?, 1?) each have at least one shape-imparting contouring structure (4, 4?, 4?) which delimits the tool cavity (3) at least in sections, wherein—on at least one tool element (1, 1?, 1?), adjacent to the contouring structure (4, 4?, 4?), there is formed at least one ventilation structure (5) for ventilating the tool cavity (3) in the closed position of the injection-moulding tool (2).
    Type: Grant

  • Patent number: 6729742
    Abstract: Solar lamp for outdoor use, in particular a garden lamp, road or street lamp or such, consisting of one or more solar module, and a housing with a storage means for electric energy (battery), which is electrically connected to the solar module, and one or more luminous body, whereby between the battery and the luminous body a circuit is provided, which reacts to signals from a light sensor attached to the solar lamp, and which enables or disables the electrical connection between the battery and the luminous body depending on the degree of brightness/darkness, whereby the housing is provided with two or more walls of different orientation which do not converge parallel to each other, and whereby one or more solar modules are arranged on each wall, or that the walls are formed by solar modules.
