Abstract
A telephone device with a handset that fits in a cradle cavity so that the outer surface of the handset is approximately flush with the surface of the cradle. A spring-loaded ejector in the cradle urges the handset against a movable tab on the cradle, that engages a lip on the handset and secures the handset in the cradle. When the tab is moved clear of the lip, the spring-loaded ejector forces the handset out of the cradle so that the handset may be grasped easily by a user, to prevent unexpected complete ejection of the handset. A tongue on the ejector engages a lip on the handset as it is ejected, so that the user must exert a small amount of additional force to remove the handset from the cradle.
