F-0439 Development of a Walking Chair : Design and Manufacturing of a Prototype for Lightening

Abstract

As the main purpose for lightening, a prototype walking chair was manufactured. In this prototype design for lightening, it was assumed that the cutting parts were replaced to the shaped parts with the aluminum sheet (thickness of 1mm) to achieve a great lightening. In order to secure the strength of parts, the sheet material and the operation of bending were examined, and the development drawing of sheet parts was drawn. A brake press machine was used for bend forming of the sheet parts. We successfully realized a lightening of the new prototype walking chair by 56% in comparison with that of the former one.
