Abstract
Abstract A wall-mounted telephone assembly is described in which reentrant surfaces are formed on both the handset and the wall-mounted base unit to increase the difficulty of dislodging the handset from its hung-up position upon the base unit. In addition the handset and base unit are magnetically attracted to each other to further increase the difficulty of dislodging it, and also for the purpose of keeping the hang-up switch in the on-hook condition when the handset is hung up. The magnetically permeable structure incorporated in the handset for this purpose also serves the purposes of acoustically isolating the microphone from the interior of the handset housing, and of focusing the desired acoustic signal upon the microphone, thus improving the acoustic performance of the telephone.

Claim 1
Independent Claim
278 words
A wall telephone assembly comprising: a base unit adapted to be mounted upon a vertical wall; a handset adapted to be removeably and replaceably hung upon said base unit when the latter is in a vertical attitude; said base unit including a rear surface adapted to be placed in juxtaposed relation to said wall, a front surface adapted to face outwardly from said wall, and upwardly facing support shelf means on said front surface of said base unit; said handset including an inner surface adapted to confront said base unit, and downwardly facing hanger projection means on said inner surface of said handset; said support shelf means sloping rearwardly and downwardly relative to said base unit when said handset is hung upon said support shelf means, said hanger projection means sloping inwardly and downwardly relative to said handset when said handset is hung upon said support shelf means, said support shelf means adapted to engage said hanger projection means when said handset is hung upon said support shelf means, whereby, when a downward force is exerted upon said handset, the interaction between said support shelf means and said hanger projection means tends to cam said handset inwardly and downwardly toward said base unit to prevent dislodging of said handset from said base unit; said telephone assembly further including magnetically cooperating means on each said handset and said base unit, positioned to magnetically attract each other when said handset is hung upon said support shelf means, whereby to bias said handset toward said base unit; said magnetic cooperating means in said handset providing focusing means shaped so as to intensify external sounds upon a microphone located in said handset.
