发明名称 Auxiliary telephone dial plate - bears symbols of animals instead of figures to permit operation by young children
摘要 <p>An auxiliary telephone dial (1) carries symbols which correspond to the numbers of the normal dial in order to permit operation by a young child which is not old enough to read figures. The auxiliary dial may be clipped into position and thus does not conflict with the regulations of the post and telecommunications authorities. The dial may be made of any transparent material on which the symbols are printed. A special symbolic telephone directory may be prepared for the child. This may be made of various materials such as paper, metal or plastic, for example, it may comprise magnetic symbols which can be placed on a metal sheet.</p>
