Technical Examples

Terrain often hinders wheeled vehicles as cars mire in sand and wheeled carts in mud. Beaches, sandy playgrounds, and mud inhibit travel of wheelchairs. A reinforced mat upon a lattice of projections provides a stable surface for wheels and wheelchairs. The projections engage the terrain as the wheelchairs cross the mat toward a destination. Also, the projections take the form of spikes or hollow tubes, the mat has porosity or spaghetti like fibers, and the lattice has various patterns. The reinforced mat may be used with larger vehicles over a variety of terrain.
