Keiko's schoolbell
The bell was a music instrument that comes in various sizes and shapes.
The expression "ring a bell" was a metaphor for memories coming back. (ENT: "Terra Nova")
A bell was used as a door chime to the Vulcan monastery at P'Jem. Sub-commander T'Pol dragged a large rope next to the door to let the bell work. (ENT: "The Andorian Incident")
Bells had been used in courtrooms for centuries. (TOS: "Court Martial"; TNG: "Encounter at Farpoint", "The First Duty"; DS9: "Rules of Engagement")
In the past, teachers used small hand-held bells to signal their students that the lesson would begin. Molly and Miles O'Brien gave Keiko a bell as a present for her first day as a teacher on Deep Space 9. (DS9: "A Man Alone")
A bell was depicted in the logo of Bell System, an Earth organization. (TOS: "The City on the Edge of Forever")
