Abstract
An indicator panel for an elevator car has a door behind which an emergency calling device is located for users of the elevator. The door is opened and closed by a door handle attached to the outer surface of the door. The handle has a body with a raised printed character formed on a front surface for identifying the emergency calling device. An enlarged lower portion of the front surface is formed by an outwardly extending flange spaced from a rear surface of the body and serving as a door operating aid. A raised information aid is formed on the enlarged lower portion and includes at least one Braille character identifying the emergency calling device. A further door operating aid is a recess formed in the rear surface of the body for retaining a pencil or the like. The body and the printed character can be formed by molding different color materials with the printed character extending from a cavity formed in the rear surface through an aperture in the front surface.
