|Wheelchair Lock System|
June 2001, Koichi Hirata
When a wheelchair is used in a ship, we hope that the wheelchair can move actively as the same of that on the ground. However, when the ship is on big waves, the wheelchair must be locked on the floor board. Several lock systems for a wheelchair are developed for a bus and a barrier-free automobile. We bought two types of the lock systems, and discussed their applications for a ship.
Hand-operated Lock System
Electric-operated Lock System
We comfirmed the operations of the wheelchair lock systems. Then we thought that they can be used on a waving ship. As an additional consideration, a passenger ship is different from a bus; the passengers spend a long time in the ship, and it is not certainly that a crew man or a helper is near a wheelchair user. So, we think to hope that the wheelchair user can operate the lock system by himself. Therefore, the electric-operated lock system is better in above two systems.
