Research on Ergonomics Design of the Height and Operation Force for Furniture Lockset

This study investigated the comfortable lockset height and the suitable force to open it. The experiment was designed and carried out with 14 participants. The data were measured by varied experimental tools. The factors that influence the comfort of lockset height such as the angle and body dimensions were analyzed. The results showed that the preferred/comfortable lockset height was below shoulder in 60 cm. The differences between male and female on comfortable force and maximum force were found. The capacity difference between male and male were significant, but the perception in comfort was almost unanimous. According to Chinese anthropometry data and ergonomics knowledge, the comfortable lockset height and the comfortable opening force were recommended.
