STRUCTURAL ARRANGEMENT FOR A FLEXIBLE WHEEL OF A WHEELBARROW AND HAND-PROPELLLED INDUSTRIAL CARTS.

摘要

A structural arrangement for a flexible wheel of a wheelbarrow and hand-propellled industrial carts consists of a single block in three parts: the outer ring (1), the central core (2) and the inner ring (3), the outer ring (1) having at its periphery the tread (15) and on each tangential side a lateral tread (12), each lateral tread (12) having a plurality of radial cavities (11) spaced around the wheel, the radial cavities (11) of a lateral tread (12) being offset in relation to the radial cavities (11a) of the opposite lateral tread (12a), and the central core (2) is a flat, massive annular wall contained in a central plane that contains the body of the wheel, a plurality of flexible structures (14) on each side of the flat wall being radially aligned with the radial cavities (11) in the outer ring (1), and the inner ring (3) consists of a circular wall (31), a reinforcing rim (32) and mass reducers (33), the mass reducers (33) being niches with radial walls.
