发明名称 Upright vacuum cleaner
摘要 A vacuum cleaner having an elongate body portion 11 which is mounted at its lower end via a neck 15 to the rear of a wheeled floor-engaging head portion 10, the body 11 being pivotable in use relative to the head about a first axis A1 for movement upwardly and downwardly and about a second orthogonal axis A2 for movement from side-to-side. A catch 17 is disposed on the neck 15 for preventing pivotal movement of the body 11 about the second axis A2 when the body 11 is disposed in its most upright position. The provision of the catch 17 improves the stability of the cleaner when the cleaner is not in use or when it is being used for above floor cleaning.

主权项 1. A vacuum cleaner comprising: an elongate body portion having a housing and a depending tubular duct; a wheeled floor-engaging head portion; a tubular neck portion at the rear of the head portion, the neck being pivoted to the head about a first axis, the duct being rotatably connected to the neck about a second orthogonal axis to define an airflow passage extending between the body and head, the body being moveable upwardly and downwardly about said first axis and from side-to-side about said second axis, the vacuum cleaner further comprising a locking device arranged to lock the duct to the neck to prevent pivotal movement of the body about said second axis when the body is disposed in its most upright position; and a catch for preventing said movement about the second axis, wherein the catch comprises a locking portion and an actuator portion, the actuator portion being arranged to abut the head of the cleaner when the body is pivoted into its most upright position to cause interengagement of the body and neck portions of the cleaner and thereby prevent movement of the body about the second axis.
