    • This invention relates to a vacuum cleaner having a vacuum cleaner housing and a pivotable handle with a grip portion. The handle is pivotably secured to the vacuum cleaner housing in such a manner that the turning axis of the handle is generally horizontal and perpendicular to the direction of movement of the vacuum cleaner when the vacuum cleaner is in a working position on a horizontal surface. The handle is maintained in a generally vertical position when the vacuum cleaner is in the working position. When an operator lifts the vacuum cleaner housing from the working position using the handle, the vacuum cleaner housing pivots to a substantially vertical position, with the position of the grip portion relative to the operator's hand remaining substantially unchanged during the lifting.
    • 本发明涉及具有真空吸尘器外壳和具有把手部分的可枢转手柄的真空吸尘器。 把手可枢转地固定到真空吸尘器外壳上,使得当真空吸尘器处于水平表面上的工作位置时,把手的转动轴线基本上是水平的并垂直于真空吸尘器的移动方向。 当真空吸尘器处于工作位置时,手柄保持在大致垂直的位置。 当操作员使用手柄从工作位置提升真空吸尘器壳体时,真空吸尘器壳体枢转到基本上垂直的位置,在提升期间把手部分相对于操作者手的位置基本上保持不变。
