Abstract
A pulling device for removing weeds or other undesirable vegetation from a ground surface. The inventive device includes an engaging assembly having a pair of gripping feet which selectively engage the weed to be pulled. A handle assembly is mounted to the engaging assembly to facilitate manual manipulation and removal of the weed.
Claims4
A weed pulling device comprising:
- an engaging means for engaging a weed to be pulled from a ground surface;
- and,
- a handle means coupled to the engaging means for facilitating manual manipulation and operation of the engaging means;
- wherein the handle means comprises a substantially hollow handle tube extending from the engaging means;
- and a T-handle coupled to a distal end of the hollow handle tube and oriented orthogonally relative thereto;
- wherein the engaging mean comprises a ear box coupled to a lower end of the handle tube opposite the T-handle of the handle means;
- a first gear rotatably mounted within the gear box, a second gear rotatably mounted within the ear box and spaced from the first gear;
- a first gripping rod fixedly secured to the first gear;
- a second gripping rod fixedly secured to the second gear, the gripping rods projecting exteriorly of the gear box and terminating at a lower distal end;
- a first gripping foot mounted to the lower distal end of the first gripping rod;
- and a second gripping foot mounted to the lower distal end of the second gripping rod;
- a rack member movably mounted within the gear box and engaged to both the first and second gears;
- a tension rod coupled to the rack member and extending through the handle tube of the handle means;
- an actuator bar movably mounted relative to the handle tube proximal to the T-handle, the actuator bar being coupled to the tension rod;
- and a spring interposed between the rack member and an interior surface of the gear box;
- wherein the actuator bar is positioned through a pair of elongated apertures formed in the handle tube to movably mount the actuator bar relative to the handle means such that a gripping of the actuator bar and the T-handle simultaneously to bias the actuator bar into contact with the T-handle will pull the tension rod;
- wherein the gripping feet comprise first and second arcuate members which extend from the respective first and second gripping rods, each of the arcuate members being shaped so as to define a sharpened piercing tip which can be utilized to pierce the ground surface, the arcuate members being semi-circular in cross section and include facing flat engaging surfaces which cooperate to frictionally engage and capture the weed.
