发明名称 Nozzle with pivoted wand
摘要 The invention described provides a nozzle that includes a pivoted wand to permit relative movement in a vertical plane between the wand and nozzle during manipulation by the operator. The center for the pivot for the wand is located at floor level. This permits friction generated forces that are imparted to the nozzle to be imposed so as to prevent unbalanced moments being generated tending to tip the nozzle during its movement over a floor or carpeting.
