Carpeting tool for a vacuum cleaner |
摘要 |
A carpeting tool for a broom-type vacuum cleaner comprising a hollow rake. The hollow rake includes a plurality of spaced hollow open-ended teeth and a plurality of spaced air passage openings interposed respectively between certain of the teeth. The hollow rake further has a pair of oppositely extending lateral hollow flange portions and a nozzle integral with and intermediary of the flange portions. The flange portions have a lowermost lateral surface from which extend the hollow teeth, and in which are formed the air passage openings. A pair of spaced apart rollers are mounted between the teeth, and extend below the open ends of the teeth to support the combined weight of the tool and vacuum cleaner when the tool is attached to the vacuum cleaner for use thereof. The rollers permit the tool to ride smoothly along the carpeting without abruptly snagging the carpeting.
