PROBLEM TO BE SOLVED: To provide a walking aid vehicle that is stable, safe, and well-designed.SOLUTION: This is a vehicle in which a person walks by coming in between the front wheel and the rear wheel to operate. A tricycle vehicle reduces the price but stability deteriorates, so that four wheels are better depending on the bodily conditions. Even with four wheels, changing directions by casters is likely to cause moving in a zigzag. Operating the front wheels with a handle is therefore preferable even with a higher price. For the prevention of tripping when entering the vehicle, the front and the rear wheels are designed to be connected only on one side of the vehicle.SELECTED DRAWING: Figure 1 |
