摘要： A portable hand-held convertible blower and vacuum unit having a primary handle on the housing and a secondary handle located on the vacuum tube attachment. The secondary handle comprises a generally compliant gripping surface and enables the operator to connect or disconnect the vacuum tube from the housing in order to convert the unit from blower to vacuum mode or vice versa. The connection between the vacuum tube and the unit housing comprises a bayonet fitting. The handle also affords a second gripping surface for use of the unit during vacuum operation. Since the handle is attached to the vacuum tube, the handle does not hinder use of the unit during blower operation during which the vacuum tube is removed from the housing. When the vacuum tube is attached to the unit housing, the longitudinal axis of the gripping surface of the secondary handle is approximately perpendicular to the longitudinal axis of the primary handle that is connected to the housing.
摘要翻译：便携式手持式可转换鼓风机和真空单元，其具有壳体上的主手柄和位于真空管附件上的辅助手柄。辅助手柄包括大致顺从的夹持表面，并且使得操作者能够将真空管与壳体连接或断开，以便将单元从鼓风机转换成真空模式，反之亦然。真空管和单元壳体之间的连接件包括卡口配件。手柄还提供了在真空操作期间使用该单元的第二夹紧表面。由于手柄附接到真空管，因此在真空管从壳体中移除的鼓风机操作期间，手柄不妨碍使用该单元。当真空管附接到单元壳体时，辅助手柄的抓握表面的纵向轴线大致垂直于连接到壳体的主手柄的纵向轴线。

摘要： An improved convertible electric blower/vac. The blower/vac includes an improved air inlet cover with an adjustable choke member. The air inlet cover also includes a pressure ring for increasing the efficiency of the blower/vac impeller when the unit is operated in the blower mode. The blower/vac also includes a blower tube and a vacuum bag collar, each with resilient tabs that engage receptacles on the blower/vac to retain the blower tube and vacuum bag collar on the unit. The housing outlet of the blower/vac includes guides that interact with longitudinal ribs on the blower tube and the vacuum bag collar to reduce unwanted rotational deflection of the blower tube and vacuum bag collar when either is engaged on the housing outlet. The blower/vac includes an improved vacuum tube for use of the blower/vac in the vacuum mode.
摘要翻译：改进的可转换电动鼓风机/ vac。鼓风机/ vac包括具有可调节扼流圈构件的改进的空气入口盖。空气入口盖还包括一个压力环，用于在鼓风机模式下操作该单元时提高鼓风机/ vac叶轮的效率。鼓风机/ vac还包括鼓风机管和真空袋环，每个都具有与鼓风机/ vac上的接收器接合的弹性接头，以将鼓风机管和真空袋环保持在该单元上。鼓风机/ vac的外壳出口包括与鼓风机管上的纵向肋和真空袋套环相互作用的导向件，以减少鼓风机管和真空袋颈环在接合在壳体出口上时的不必要的旋转偏转。鼓风机/ vac包括在真空模式中使用鼓风机/ vac的改进的真空管。

摘要： A discharge chute assembly (30) includes a chute (32) and a pivotal deflector (34), the overlapping end portions of which define a partial spherical or ball joint (40) which maintains a tight seal against backflow and leakage over the entire range of rotation and deflection of the assembly. The assembly (30) is preferably secured to a rotatable base (54) by means of lower pivots (70) and a releasable fastener (72) for collapsibility.
