Abstract

Abstract The unit incorporates a transceiver, having a channel changing mechanism, and a radio, having a radio tuner, enclosed in a common housing for conjoint mounting. A transceiver control shaft has an inner end in operative connection with the channel changing mechanism and an outer end having a first gear secured thereto. A tubular outer shaft extends through an opening in the front wall of the housing and has a second gear secured to its inner end. An inner shaft extends coaxially through the tubular shaft, and respective control knobs are secured to the outer ends of the tubular shaft and the inner shaft. A pair of levers have their inner ends interconnected by a pivot and their outer ends respectively pivoted on the transceiver control shaft and tubular shaft, and an idler gear is freely rotatable on the pivot and meshes with the first and second gears to constitute a driving connection therebetween. The tubular outer shaft extends through an elongated slot in the front wall of the housing, and the inner end of the inner shaft is connected by one or more universal joints to the radio tuner.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 215 words
A combined transceiver and radio unit, incorporating a transceiver, having a channel changing mechanism, and a radio, having a radio tuner, enclosed in a common housing, having a front wall, for conjoint mounting, said unit comprising, in combination, a transceiver control shaft, having an inner end in operative connection with said channel changing mechanism, and an outer end; a first gear secured to said outer end of said control shaft; a tubular outer shaft extending through an opening in said front wall, and having inner and outer ends; a second gear secured to the inner end of said outer shaft and in driving connection with said first gear; an inner shaft, extending coaxially through said tubular shaft, having an inner end in operative connection with said radio tuner, and an outer end; respective control knobs secured to the outer ends of said outer and inner shafts; a pair of levers having inner ends interconnected by a pivot and outer ends respectively pivoted on said transceiver control shaft and said outer shaft; and an idler gear freely rotatable on said pivot and meshing with said first and second gears to constitute said driving connection therebetween; said levers and said idler gear providing for relative displacement of said tubular outer shaft relative to said transceiver control shaft.
Claim 2
Dependent Claim 215 words
A combined transceiver and radio unit, incorporating a transceiver, having a channel changing mechanism, and a radio, having a radio tuner, enclosed in a common housing, having a front wall, for conjoint mounting, said unit comprising, in combination, a transceiver control shaft, having an inner end in operative connection with said channel changing mechanism, and an outer end; a first gear secured to said outer end of said control shaft; a tubular outer shaft extending through an opening in said front wall, and having inner and outer ends; a second gear secured to the inner end of said outer shaft and in driving connection with said first gear; an inner shaft, extending coaxially through said tubular shaft, having an inner end in operative connection with said radio tuner, and an outer end; respective control knobs secured to the outer ends of said outer and inner shafts; a pair of levers having inner ends interconnected by a pivot and outer ends respectively pivoted on said transceiver control shaft and said outer shaft; and an idler gear freely rotatable on said pivot and meshing with said first and second gears to constitute said driving connection therebetween; said levers and said idler gear providing for relative displacement of said tubular outer shaft relative to said transceiver control shaft.
Claim 3
Dependent Claim 27 words
A combined transceiver and radio unit, as claimed in claim 1, including universal joint means constituting the operative connection between said inner shaft and said radio tuner.
Claim 4
Dependent Claim 26 words
