Abstract
A wheelbarrow has a frame, having a top portion (12) and an undercarriage portion (14). There is an open topped vessel (15) mounted on the top portion (12) of the frame, and a pair of handle bars (16, 17) extending rearwardly and integrally from the top portion (12) of the frame. The wheelbarrow also has a pair of ground engagable legs (18, 19), and a front wheel (20) is connected to a front part of the undercarriage portion (14) of the frame, and a rear wheel (21) is connected to a rear part of the undercarriage portion (14) of the frame. The rear wheel (21) is aligned with the front wheel (20). There are pivot axis means (22, 24, 25) of the wheelbarrow for allowing the top portion (12) of the frame to pivot relative to the undercarriage portion (14) of the frame. Manually controllable linkage means (26,27,29,30,31,32) are also provided which are adjustable between first and second positions for allowing a user to link the top and undercarriage portions (12, 14) of the frame when in a first position so that they are unable to pivot relative to each other about the pivot axis means, and for allowing a user to unlink the top and undercarriage portions (12, 14) of the frame when in a second position so that they are able to pivot relative to each other about the pivot axis means.
