Abstract

Double decker storage racks are established in communal facilities for efficient bicycles storage. However, an upper rack of the rack is rarely utilized, because its workload to users in parking operation is large. This paper discusses a design method of a double decker bicycle storage rack equipped with an original load reduction mechanism. First, questionnaire and electromyogram measurement are conducted, and it becomes clear that the physical load is the largest when users lift the upper rack with bicycle. Next, a load reduction mechanism that consists of a compression spring and a slider is developed, and the mechanism is installed in a double decker bicycle storage rack on market. Finally, it is clarified that the mechanism can reduce the physical load of users effectively, from the results of questionnaire and several evaluation experiments.
