Abstract
A mechanical weed remover comprises an elongate, length-adjustable shaft with pivotal weed-gripping jaws at its lower end and handle grips at its upper end. The handle grips include means for manipulating the jaws into weed-gripping engagement, and the adjustable nature of the shaft allows it to be used comfortably in standing position by users of different heights. The device also includes a facility whereby the jaws may be releasably locked in weed-gripping engagement, and the jaws may be designed to prevent scraping up of top soil when gripping onto a weed.
Claims14
A mechanical weed removal device comprising a pair of relatively movable jaw members, and means for moving the jaw members into and out of weed-gripping engagement, wherein terminal ends of the respective jaw members are respectively offset in closed position of the jaw members to prevent scraping up top soil when closing the jaw members with one of the terminal ends in ground engagement wherein one of said jaw members comprises a stationary jaw member on one end of an elongate shaft means, the other of said jaw members being mounted on the shaft means for movement toward and away from said one jaw member, the terminal edge of the stationary jaw member overlapping the terminal edge of the other jaw member so that when the terminal edge of the one jaw member is in ground engagement, the terminal edge of the other jaw member clears the ground, the device further including handle means on the other end of said shaft means, the handle means including operating means for the other of said jaw members, wherein the operating means comprises a hand lever pivoted on the shaft means and connected to the other jaw member by a linkage means extending along the shaft means, and the device including engageable and disengageable locking elements on the hand lever and a hand grip portion of the shaft means respectively for releasably clamping the jaw members in weed-gripping engagement, wherein the locking elements comprise complementary opposed ramp-like elements mutually cammed into locking engagement when the hand lever is moved towards the hand grip and released by relative lateral displacement of the hand lever and hand grip.
A mechanical weed removal device comprising a pair of relatively movable jaw members, and means for moving the jaw members into and out of weed-gripping engagement, wherein terminal ends of the respective jaw members are respectively offset in closed positions of the jaw members to prevent scraping up top soil when closing the jaw members with one of the terminal ends in ground engagement wherein one of said jaw members comprises a stationary jaw member on one end of an elongate shaft means, the other of said jaw members being mounted on the shaft means for movement toward and away from said one jaw member, the terminal edge of the stationary jaw member overlapping the terminal edge of the other jaw member so that when the terminal edge of the one jaw member is in ground engagement, the terminal edge of the other jaw member clears the ground, the device further including handle means on the other end of said shaft means, the handle means including operating means for the other of said jaw members, wherein the operating means comprises a hand lever pivoted on the shaft means and connected to the other jaw member by a linkage means extending along the shaft means, the device including means for adjusting the length of the shaft means, and means for making equivalent length adjustments to the linkage means enabling the device to be used for weed removal by persons of different height from a standing position.
