Abstract
There is disclosed a compact telephone instrument with a telescoping operation. A first housing has a conventional telephone receiver located within a hollow recess thereof. The housing is removably secured to a bottom housing which contains a dialer assembly. A series of guide mechanisms are formed in both housings and are used to accommodate a third housing containing a telephone transmitter. The third housing is slidably mounted within the receiver and dialer housings to enable on-hook and off-hook operations by sliding and extending outwardly for off-hook operation and by pushing the housing inward for on-hook operation. The transmitter housing is accurately guided between the receiver and dialer housings by means of the guide mechanisms to insure accurate and reliable operation relatively independent of the nature of the force exerted by a user on the transmitter housing when operating the instrument. The movement of the transmitter housing between the on and off hook positions automatically activates a hook switch arrangement by means of tabs which are permanently secured on slide members associated with the transmitter housing and which tabs actuate leaf spring switches located on a component board positioned between the dialer and receiver housings. The telephone instrument employs conventional telephone components to further assure reliable electrical and mechanical operation.
