Abstract
A cabinet includes a cabinet body, multiple drawers and a safety device. The drawers are mounted moveably in the cabinet body. The safety device is mounted in the cabinet body and has a control member and multiple hook members. The control member is mounted on the rear panel of the cabinet body and has a supporting base, a pivotal member and a resilient element. The pivotal member is mounted pivotally on the supporting base. The resilient element is connected to the supporting base and the pivotal member. The hook members are mounted respectively on the drawers and are aligned with the pivotal member. When a drawer is opened, the corresponding hook member pushes the pivotal member to pivot the pivotal member and stretch the resilient element and a hook flange on the pivotal member engages the hook members on other drawers to prevent other drawers from being opened.
