ABSTRACT:
The present invention provides a blower-vacuum device having means for collecting garden waste, the garden waste collecting means comprising: an attachment part (42) for receiving a garden waste receptacle; and a garden waste receptacle (30) for removable engagement with the attachment part; wherein the attachment part (42) comprises an arcuate groove (44); and the garden waste receptacle (30) comprises a band (33) defining a mouth (35) of the receptacle for sliding engagement with the groove. Thus the receptacle may be easily removed from the attachment part of the blower-vacuum device merely by sliding the band (33) of the receptacle out of the groove (44), whereupon the receptacle may then be emptied of garden waste by tipping it upside-down. In a preferred embodiment, the band (33) is made of a resilient material, whereby when the band is inserted into the groove (44), the band is constrained by the groove and the mouth (35) of the receptacle defined by the band is made narrower than when the band is withdrawn from the groove. Thus when the band is withdrawn from the groove (44), the mouth (35) of the receptacle opens out (arrows R and S), making it easier to empty.
