Patent CA-2268087-A1 (CA)
Title: Folding wheelbarrow
Inventor: MCDONALD MARK CHESLEY
IPC: B62B1/20
Filed: 1997-10-06
Abstract: A folding wheelbarrow is adjustable between erected and folded positions and comprises a pair of handle members (213, 214), a pair of leg members (219, 220), a wheel (216) and a collapsible (222) container of flexible sheet material. Forward portions of the handle members are hingedly connected together to form a kicker portion when erected, and rear portions of the handle members are laterally spaced apart for gripping. Forward portions of the leg members are hingedly connected together and located above the forward portions of the handle members when the wheelbarrow is erected, and rear portions of the leg members provide spaced apart legs to support the wheelbarrow. Each leg member is hinged to an adjacent arm member for rotation about a respective main hinge axis. The wheel is mounted for rotation about a transversely extending axle which is hingedly and slidably connected to the forward portions of the handle members. The collapsible container is made of a flexible sheet material and is located between the forward portions of the leg members and the rear portions of the handle member. A stiffening structure extends between the arm members and the leg members to limit relative movement therebetween about the main axis to stiffen the wheelbarrow when erected. A  limiting structure limits rotation of the handle members about the handle axes.
