发明名称 Signal seat for children
摘要 This invention relates to disciplinary devices to teach young children proper behavior in general, and more specifically to a unique, tamper-proof weight activated signaling mechanism incorporated into a stool, which a child must sit on for disciplinary reasons, whereby the removal of the child's weight from the seat portion of the device, causes the signaling mechanism to be activated.
