Students, Department of Mechanical Engineering, K.Ramakrishnan College Of Engineering, Tiruchirappalli,Tamilnadu,India-621112. ------------------------------------------------------------------------***------------------------------------------------------------------------ABSTRACT: The effective design of multipurpose chair for disabled person is to reduce the transferring time inside the home. The design is also used for sleeping, eating, drinking, reading and writing is possible for in a single design of chair. There are salient features which are added with the design of chair to improve the performance of the existing design. The distance between the front and rear axle distance can be adjustable for threaded rod and fixed bolt. The vertical height also adjustable for with respect to our requirement. The adjustable threaded rods are rotated with respect to the battery operated motor. The forward and reverse direction moment can be possible by operating the needles. The direction also controlled by the front wheel with respect to needle movement. The sliding backbone movement bed is possible by using connecting lever. The frame is made of strong materials. The design of all the operation occurs with respect to needle movement and connecting lever. The battery is rechargeable and the sliding tray, number of boxes are used to protect the various things in tray and boxes such as laptops, books, documents, water bottles, remote and mobile phones. The sliding table is provided for writing and eating purpose. In the design is very helpful to disabled person free to move at any place in home. Key words - External thread, adjustable height, rotary bed, tray, protective boxes. 1. INTRODUCTION In our day to day life lot of innovative machines and devices are coming. The innovations are to reduce usage of manpower and increasing the productivity in all fields. The main reason for new machines is to create the human comfortable zone. The transportation can be easily by using cycles, bikes, cars and air craft. But the normal human being can be take any decision at any places. But the disabled persons are directly depends on others and self-transportation is not possible. So it can be rectified that special care takers are selected for this places. The disabled persons can’t able be move from one place to another place by their own. The disabled persons sit in the same place for full day, month and year. It will create a impact that is very dangerous. All the disabled persons are individually strong with their areas such as drawing, logical thinking, reading, writing and listening. The disabled person brain is capable to capture some things in all the kind of situations. The advanced treatments are very helpful to cure the problems. But some of the problems are not rectified. So the disabled person is directly depended on parents, friends and care takers. 2. LITERATURE REVIEW In report says that totally eighty percent of the disabled persons are living in developing countries. In every year twenty million women disabled with naturally. In ancient days there is no special chairs for disabled persons. But now a days there are many innovators are introduced the simplified design of wheel chairs. The previous design of chairs are only sitting purpose only. But our design is totally modified with the help of advanced equipment. There is a lot of things kept inside the design and number of works are possible in a single design.
