Abstract

See full text

A device for removing weeds from the ground comprises an elongated shaft, a handle mounted to an upper end of the shaft, a pair of blades mounted for opposed pivotal movement at a lower end of the shaft, and a plunger. Each blade has an upper section located above a pivot point of the blade and a lower section located below the pivot point. The plunger is mounted for reciprocal sliding movement between an extended position intermediate the lower sections of the blades and a retracted position intermediate the upper sections of the blades. The plunger and the upper sections of the blades include cam surfaces configured such that movement of the plunger from the extended position to the retracted position forces the upper sections of the blades away from one another, whereby tips of the blades are forced to converge towards one another to capture the weed and accompanying root structure. The weed and surrounding soil plug can be released by squeezing a hand-lever.
