Abstract
Abstract A phone coupler for data communication having integrally mounted therein the microphone, an inductive pick-up coil, and an on-off switch. The microphone and pick-up coil are encapsulated into a unitized structure and centrally positioned for utility in the coupler. A spring-positioned button switch protrudes into the phone receiving area of the phone coupler. The button-like protrusion is part of an elongated structure passing through said unitized structure into an actuating position with a microswitch.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
Apparatus for coupling a telephone communication terminal to a transmission line including an electro-acoustical transducer and an inductive pick-up coil; a housing of omnidirectionally movable structure having an upper portion circular opening adapted to receive said terminal, and a lower portion circular opening; a casing for encapsulating said transducer and inductive pick-up coil, said casing having an outside size adapted to be retained with said lower portion circular opening; said casing having a pair of discontinuities to permit electro-acoustical communication with said terminal; said casing including means for fixedly positioning said transducer and inductive pick-up coil therein; and a switch for actuating said terminal fixedly positioned at a lowermost region of said housing and having contact means positioned in the uppermost portion of the housing.
Claim 2
Dependent Claim
125 words
Apparatus for coupling a telephone communication terminal to a transmission line including an electro-acoustical transducer and an inductive pick-up coil; a housing of omnidirectionally movable structure having an upper portion circular opening adapted to receive said terminal, and a lower portion circular opening; a casing for encapsulating said transducer and inductive pick-up coil, said casing having an outside size adapted to be retained with said lower portion circular opening; said casing having a pair of discontinuities to permit electro-acoustical communication with said terminal; said casing including means for fixedly positioning said transducer and inductive pick-up coil therein; and a switch for actuating said terminal fixedly positioned at a lowermost region of said housing and having contact means positioned in the uppermost portion of the housing.
Claim 3
Dependent Claim
22 words
Apparatus as set forth in claim 1 wherein said casing has a varying depth to accommodate the varying sized components retained therein.
Claim 4
Dependent Claim
23 words
Apparatus as set forth in claim 1 wherein said casing has a non-metallic cap and wherein said discontinuities are a pair of apertures.
Claim 5
Dependent Claim
29 words
Apparatus as set forth in claim 3 wherein said casing has another opening to permit the passage of said contact means from one opening of said housing to another.
Claim 6
Dependent Claim
40 words
Apparatus as set forth in claim 2 wherein said means for fixedly positioning said transducer and receiver comprises cementing said transducer to one depth of said casing and cementing the inductive pick-up coil to the other depth of said casing.
Claim 7
Dependent Claim
54 words
Apparatus as set forth in claim 1 wherein said switch includes a body portion with a contact positioned in the lower opening of said housing and a push button extending from its one end adjacent said contact to its other end in the upper opening of said housing to be actuated by said terminal.
Claim 8
Dependent Claim
46 words
Apparatus as set forth in claim 6 wherein said push-button comprises an elongated structure, a cap fitted at the top end, and a rod adjacent said contact at its other end, a spring positioned in said elongated structure to return said push-button to an original position.
Claim 9
Dependent Claim
30 words
Apparatus as set forth in claim 7 further comprising means for joining said spring to one end of said rod and means for retaining said spring in said elongated structure.
Claim 10
Dependent Claim
31 words
Apparatus as set forth in claim 7 wherein said rod has positioned at its one end an element having a taper to physically engage said contact when it is moved downwardly.
Claim 11
Dependent Claim
33 words
Apparatus as set forth in claim 7 wherein said elongated structure extends through said aperture in said casing and wherein said cap to said housing protrudes into the upper portion of said housing.
