Abstract

A convenient versatile telephone handset has one set of telephone activating keys and another set of computer control keys. The special telephone handset can also have a card-receiving slot and a recessed mouthpiece. Advantageously, the flexible telephone handset is particularly useful for business travelers in airplanes, trains, and buses to link up to reservation systems and other data bases.

Claims

a front surface having an earpiece and a mouthpiece;

a back surface;

end walls extending between and connecting said front and back surface, said end walls comprising a top and bottom;

sidewalls extending between and connecting said top and bottom;

one of said surfaces defining a card-receiving slot;

said slot having an enlarged inlet opening defining a mouth; and

said mouth comprises a latch-receiving opening.

2. A telephone handset in accordance with claim 1 wherein said slot is located on said front surface adjacent one of said sidewalls.

3. A telephone handset, comprising:

substantially planar imperforate sidewalls including a left sidewall and a right sidewall, said sidewalls being substantially parallel and rectangular with rounded corners;

substantially planar and parallel end walls extending transversely between and connecting said sidewalls, said end walls including a substantially imperforate top wall providing a top and a bottom wall providing a bottom, said end walls being substantially rectangular with rounded corners, and said bottom wall defining a cord-receiving opening in proximity to one of said said sidewalls and providing a socket;

a back surface providing a back extending between and connecting said end walls and said sidewalls, said back surface having a substantially planar back portion and being substantially rectangular with rounded corners, and said back having an array of finger engagable keys;

a front surface providing a front extending between and connecting said end walls and said sidewalls, said front surface having substantially planar front portions positioned substantially parallel to said planar back portions of said back, said front having an earpiece adjacent said top, a mouthpiece in proximity to said bottom, an intermediate control section positioned between said earpiece and said mouthpiece, said intermediate control section having a set of telephone activating control keys facing opposite said finger engagable keys, and said front defining a substantially vertical elongated card-receiving slot extending through said end walls, said slot being substantially parallel and disposed adjacent another one of said sidewalls, said slot having an enlarged card-receiving inlet opening providing a mouth with a substantially triangular lower section and a substantially rectangular upper section, said mouth having a substantially straight outer side disposed substantially contiguous to said slot along said adjacent sidewall, an upright inner side along said upper section positioned substantially parallel to said outer side, and a tapered angled side providing a cam surface along said lower section diverging inwardly and upwardly;

said telephone activating control keys selected from the group consisting of resilient depressible key pads and pushbuttons;

said earpiece comprising a raised earpiece extending forwardly of said planar front portions, said raised earpiece having a substantially rectangular periphery as viewed from the front with rounded corner, said earpiece having a substantially planar sloping portion extending upwardly away from said mouth-piece at an angle of inclination ranging from about 15 degrees to about 75 degrees with a substantially circular earpiece portion defining a series of apertures providing ear holes surrounded by said rectangular periphery, and said raised earpiece having an inverted U-shaped top portion positioned flush and in substantial coplanar relationship with said top wall and having rounded corners; and
