摘要:
#$%^&*AU2009201455B220121018.pdf#####ABSTRACT OF THE DISCLOSURE A manually operable weed remover consists of a cluster of pivotable and rotatable spikes attached to a handle. When positioned over the center of a weed and downward pressure is applied, either by pushing on a bar handle or stepping on a foot rest, a bottom 5 flange is forced up by the ground surface as the spikes are forced into the ground around the weed. The spikes are directed through apertures in the moveable flange and movement of the flange causes the spikes to close around the root of the weed. The insertion motion of the spikes further causes the spike mounting device to rotate relative to the handle and the weed. Thus, as the spikes are being inserted into the ground, the 10 spikes rotate thereby separating the weed root from the adjacent ground. The weed may then be pulled from the ground by upward pressure on the tool. 151/6 24 20 10 14 12 26 18 0 22 67 FIG. 1
