Abstract

An expandable telephone housing has been developed which allows for easy lateral expansion. The housing contains front and rear slides and an end cap which is removable. For expansion the end cap is removed exposing a mating mechanism for locking to an expansion housing. The expansion housing contains a face plate having additional lamps or buttons. New, and longer, front and rear slides are positioned along the front and rear edges of the combined housing to secure the now elongated structure. When assembled, the combined housings give the appearance of a single housing. The rear slide may be arranged for securing an auxiliary display unit.
