Patent

CA 2291159

A wheelbarrow contains a tray (20), a frame (30), two legs (41 and 42), two handles (51 and 52), two axle brackets (71 and 72), a wheel axle (80), and a wheel (90). The wheelbarrow also contains two spaced apart roll bars (61 and 62) extending from the frame in a forward and downward direction to a point forward of the forward edge of the tray, then curving upward and extending vertically for a distance of at least about six inches (about 15 cm). The upward curve of the roll bar is located below the wheel axle. The upward curve of the roll bar contacts the ground and forms a fulcrum when the wheelbarrow is raised at an angle of not greater than about 40° and so that the wheelbarrow will balance in a vertical resting position on the vertical extensions of the roll bars if the wheelbarrow is released after being raised at an angle of not greater than about 70°.

Cette invention se rapporte à une brouette comportant un plateau (20), un châssis (30), deux pieds (41 et 42), deux poignées (51 et 52), deux supports d'axe (71 et 72), un axe de roue (80) et une roue. Cette brouette comporte également deux barres stabilisatrices espacées (61 et 62) qui font saillie vers l'avant et vers le bas à partir du châssis jusqu'à un point à l'avant du bord avant du plateau, puis sont recourbées vers le haut et montent verticalement sur une distance d'environ six pouces (environ 15 cm). La courbe ascendante de la barre stabilisatrice entre en contact avec le sol et forme un point fixe lorsqu'on lève la brouette d'un angle inférieur ou égal à 40 DEG et de façon que la brouette trouve son équilibre dans une position de repos vertical, sur les prolongements verticaux des barres stabilisatrices, si l'on relâche la brouette après l'avoir soulevée d'un angle inférieur ou égal à 70 DEG environ.
