Title
(EN) WHEELED LAWN CARE UNIT
(FR) UNITE D'ENTRETIEN DES GAZONS MONTEE SUR ROUES
Abstract
(EN)
A compact, lightweight and easy-to-use wheeled lawn care unit (10) comprising a two-wheeled carriage (12), a power source (28), plurality of tools (86, 88, 90, 92, 94, 95, 96) which may be alternatively connected to the power source (28), a handle (37) and a boom (38) connecting the selected tool to the power source (28). The power source (28) is pivotally connected to the carriage at a location within its footprint (93). The unit has a low center of gravity by placing the power source pivot (30) and center of gravity within a cylinder (22) defined by wheels (16, 18). The booms (38, 40) extend horizontally from the power source (28) and is of a split boom configuration which allows selective rotation for the boom portions relative to one another. An edger (86) that can be selected for the unit, which includes a spring-loaded wheel (114). The edger may be rotated from a non-working position (130) where the edger blade does not contact the ground to a working position (132) by rocking a handle (37) behind the carriage (12) forward against the bias of the spring. A second more compact version has the shield (238) positioned on the boom (40).
(FR)
La présente invention concerne une unité d'entretien (10) des gazons montée sur roues qui est compacte, légère et de mise en oeuvre commode. Elle comporte un chariot à deux roues (12), une source motrice (28), une pluralité d'outils (86, 88, 90, 92, 94, 95, 96) pouvant se raccorder tour à tour à la source motrice (28), un guidon (37) et une flèche (38) de raccordement de l'outil sélectionné à la source motrice (28). La source motrice (28) est connectée pivotante sur le chariot en un point à l'intérieur de sa surface d'encombrement (93). L'unité bénéficie d'un centre de gravité bas du fait que le pivot (30) de la source motrice et le centre de gravité sont placés dans un cylindre (22) défini par les roues (16, 18). Les flèches (38, 40), qui partent à l'horizontale depuis la source motrice (28), présente une configuration segmentée, ce qui permet une rotation sélective des segments de la flèche les uns par rapport aux autres. On peut choisir pour l'unité un dresse-bordure (86), qui comporte une roue (114) sous charge de ressort. Ce dresse-bordure peut par rotation passer d'une position non opérante (130) selon laquelle la lame du dresse-bordure ne touche pas le sol à une position active (132), et ce, par basculement vers l'avant d'une manette (37) placée derrière le chariot (12), de façon à contrarier la détente du ressort. Une seconde version plus compacte comporte un capot (238) englobant la flèche (40).
