  • Patent number: 11912218
    Abstract: A bumper crossmember comprising a wave structure oriented in the vertical direction (z direction), wherein the wave structure comprises at least three apex structures which extend in the bumper crossmember longitudinal direction and are adjacent in the vertical direction. This crossmember comprises a first length section that follows its longitudinal extent, at least one second length section that follows its longitudinal extent, and at least one transition section that is arranged respectively between these length sections. In the second length section, the wave structure is inverted with respect to the first length section, in that the opening direction of the apex structures switches in the transition section. In the transition section, there is at least one additional apex-forming structure, the apex of which is offset in the frontal direction (x direction) with respect to a frontal plane (yz-plane) in which at least two apex structures that are adjacent in the longitudinal sections lie.

  • Publication number: 20060225315
    Abstract: The inventive iron comprises a water container having a filling orifice (5) which is provided with a rigid cap (7) having a closure face (71) visible through the orifice. The cap (7) consists of retaining means which are embodied in such away that a first vertical pressure on the visible face (71) of the cap opens the orifice (5), thereby indenting said cap retaining means into the orifice (5), whereby making it possible to fill the container with water. When said retaining means are released, the orifice (5) is closed by the action produced by a second pressure on the visible face (71) of the cap.

  • Patent number: 6115949
    Abstract: The invention provides a drip valve having few parts. The drip valve is arranged between the water tank and the evaporation chamber. An adjustment part is mounted in the handle and has an eccentric and helical sliding track with latching grooves. The adjustment part is formed as a wheel segment with bearing pins. The valve includes a valve rod with an angled end. The angled end of the valve rod is engageable in the latching grooves so as to hold the rod and valve in place.
