Design of a New Carrying Device Based on the Stair Handrail

Abstract

Abstract. This paper describes a power assisting device with the help of the stair handrail. The slope of the stair handrail not only changes the forced direction of the objects, but also changes the ways of putting strength. The adjustable clamp system can adapt to different types of stair handrails.The fixed device canprevent it from tilting. The brake mechanism can control the gliding speed of the device. And the ratchet wheel can prevent the device from sliding down. In addition, the device is foldable, not only can it transport with the help of the stair handrail, but also i t can transport on the ground, so the course of the transit is more convenient and fluent.
