Abstract: A toilet seat includes a seat ring (10) and means (14, 15, 16) for positioning the same relative to a toilet bowl. The positioning means include at least one pair of interconnected arms (14, 15) which are movably mounted on the seat ring (10) and capable of being brought synchronously to positions in which they engage the toilet bowl. The arms (14, 15) of each pair are designed for engagement with opposite inner surfaces or outer surfaces of the toilet bowl and are interconnected so as to move synchronously in opposite directions as they are brought to their positional settings.

Abstract: Shears for cutting metal sheet include first and second jaws pivotably interconnected by a jaw joint. The jaws have respective cutting edges located forwardly of the jaw joint, and which are arranged to cross one another at a crossing point which moves during a cutting operation. The cutting edges are configures to cross one another at a substantially constant angle during a cutting operation. The second jaw includes an extension extending rearwardly of the jaw joint. The first jaw has a rigidly attached first gripping handle. A second gripping handle is pivotably connected to the first handle by a handle joint located rearwardly of the jaw joint. The second handle engages a surface of the extension by a sliding contact, whereby a distance between the jaw joint and the sliding contact increases during a cutting operation.
