  • Patent number: 9281602
    Abstract: A socket has a plug board with first plug-in openings for appropriate pins of a plug of a first standard and with second plug-in openings for appropriate pins of a plug of a second standard. Provided in a spacing to the plug board are a first type of contact mounts for receiving plug pins of the first standard, and a second type of contact mounts for receiving plug pins of the second standard. Provided between the contact mounts and the plug board are protection elements which are movable out of a closed position in which the first and second plug-in openings are blocked, into an open position in which the plug-in openings are open. The protection elements are pretensioned into their respective closed positions by spring elements. The first and second protection elements are pretensioned into their respective end positions in different directions of movement by the spring elements.

  • Patent number: 7367248
    Abstract: A screwtop opener with a first handle and a second handle which can be pivoted in relation to the first handle. A first clamping jaw is formed on the first handle and a second clamping jaw is formed on the second handle. A screwtop can be grasped by the two clamping jaws. A distance between the clamping jaws can be reduced by pivoting the two handles against each other. In accordance with this invention, a first clamping jaw is embodied on a straightedge, which can be pushed into the first handle and can be arrested in a multitude of positions with respect to the first handle. Thus, it is possible to achieve a short linear extension of the screwtop opener without foregoing the comfort of being able to also grasp and open large screwtops.

  • Patent number: 7100473
    Abstract: A screw lid opener is disclosed which can be converted in an extremely simple manner from one lid radius to another With a screw lid opener having a lever-like handle with a clamping device thereon for holding a screw lid, the lid radius is set by three clamping cheeks for clamping on a screw lid. The clamping jaws are arranged at a distance from a center between the clamping jaws. In accordance with exemplary embodiments, at least one clamping jaw, whose distance from the center can be changed, is provided. This permits the conversion from one lid radius to another. Advantageously all three clamping jaws are embodied to be movable in the same way. With the same spectrum at various radii of lids, this results in a shorter travel for the individual clamping jaw.
