摘要： An electric vacuum cleaner has a floor engaging unit, a generally vertically extending handle assembly pivotally affixed to the rear of the floor engaging unit, and a porous bag assembly mounted to the front of the handle assembly. The handle assembly is hollow to direct dust-laden air from the floor engaging unit to the bag assembly. A bottom plate, under the brush roll, has notches at its edges to enhance edge cleaning, and front wheels for the cleaner. Ridges are provided in the floor engaging unit to prevent improper assembly of the drive belt. The handle assembly is resiliently biased upwardly, and a release is provided thereon to enable relaxation of forces on the porous bag of the porous bag assembly, to facilitate changing of the bag.

摘要： A sole plate and rake latch assembly in a vacuum cleaner nozzle is provided which is capable of making the nozzle effective for both raking and cleaning shag-type rugs and rugs with short nap. The sole plate is provided with forwardly and rearwardly inclined walls extending upwardly from an air intake opening disposed lengthwise therein. A pivotal rake member is mounted adjacent the upper edge of both the forwardly and rearwardly inclined walls with the inclined walls preferably having recesses formed in their outer surface to receive the lower ends of the rake members in nesting position therein. Several rake latching means are provided which enable the rake members to be moved into either raking position or in nesting position.

摘要： A suction cleaner capable of rapid conversion for either on-the-floor or above-the-floor cleaning, is disclosed. The cleaner includes an elongated housing arranged in a generally upright manner and having an elongated, upwardly extending handle at the rear side thereof. A floor nozzle is connected to the lower end of the housing so that the latter "floats" on the surface of a rug or carpet being cleaned. A suction control valve assembly is mounted in a cavity in the rear of the housing so as to be easily removable therefrom. The valve assembly is connected to conduit means extending between a subatmospheric pressure filtering chamber in the housing and the floor nozzle. An auxiliary suction inlet communicates with the filtering chamber, upstream from the suction valve assembly, and one end of an auxiliary suction hose is permanently connected to the auxiliary inlet. The valve of the suction control valve assembly shifts from a position establishing communication between the floor nozzle and the filtering chamber when the cleaner housing is inclined rearwardly for on-the-floor cleaning and to a position preventing communication between the floor nozzle and the filtering chamber when the cleaner housing is in an upright position for above-the-floor cleaning. A recess is provided in the rear side of the handle to receive and releasably retain the suction hose when the latter is not in use and another cavity is provided between the housing and handle to receive an above-the-floor cleaning tool when this tool is not in use. The major components of the cleaner are compactly arranged so that the overall bulk of the cleaner is reduced.
摘要翻译：公开了一种能够快速转换为地面或地板上清洁的吸尘器。清洁器包括以大致直立的方式布置的细长壳体，并且在其后侧具有细长的向上延伸的手柄。地板喷嘴连接到壳体的下端，使得后者在被清洁的地毯或地毯的表面上“漂浮”。吸入控制阀组件安装在壳体后部的空腔中，以便容易地从其中移除。阀组件连接到在外壳中的低于大气压的过滤室和地板喷嘴之间延伸的管道装置。辅助吸入口与吸入阀组件上游的过滤室连通，辅助抽吸软管的一端永久地连接到辅助入口。当清洁器壳体向后倾斜以用于地板上清洁时，吸入控制阀组件的阀门从建立地板喷嘴和过滤室之间的连通的位置移动，并且防止地板喷嘴和过滤室之间的连通的位置当清洁器壳体处于用于地板上清洁的直立位置时。在手柄的后侧设置有凹口，以在吸入软管不使用时容纳和可释放地保持抽吸软管，并且在壳体和手柄之间设置另一个空腔以在该工具是不使用清洁器的主要组件紧凑地布置，使得清洁器的整体体积减小。

摘要： A vacuum cleaner has an elongated porous outer bag for holding a filter bag over an air outlet. A hanger within the outer bag is positioned to suspend the outer bag from the vacuum cleaner, as well as to hold a pocket within the outer bag, so that spare filter bags may be held within the porous outer bag and an end flap extending into the outer bag.
