Definitions

  • a portable radio having three coaxially rotatable interconnected sections defining a casing with one section housing the primary components of the radio including a speaker, a tuner, a volume control, and a battery, a second section disposed in end-to-end relation thereto, and a third section in the from of a ring member rotatably mounted on said first section with said second and third sections connected to primary components housed in said first section for controlling operation of the radio and with means provided to give a visual indication of the tuning of the radio.
  • portable radios are well-known, it has not been known prior to our invention to provide a cylindricalshaped portable radio which lends itself to decorative exterior treatment and which provides all of the functions of a conventional portable radio and, additionally, provides for storage of articles and a configuration acceptable for carrying by women.
  • An object of this invention is to provide a new and improved portable radio having a construction and configuration not heretofore known.
  • Another object of the invention is to provide a portable radio composed of a plurality of tubular sections with first and second sections disposed in coaxial relation, and adjustment of one section relative to the other controlling functions of primary components carried in the other section and with a third section in the form of a ring member and coaxial with said first and second sections to control an additional function of the radio and all of the sections constructed and arranged to provide a cylindrical casing for the portable radio.
  • Still another object of the invention is to provide a portable radio having a first tubular section housing primary components of the radio, such as a speaker, a tuner, and a volume and on-off control with a second tubular section disposed in end-to-end relationn with the first section and rotatably associated therewith and connected to the tuner whereby rotation of said second section controls tuning of the radio and a third section in the form of a ring surrounding a portion of said first section and drivingly connected to the on-oif and volume control to control said functions by rotation thereof relative to said first section.
  • Still another object of the invention is to provide a portable radio as defined in the preceding paragraph wherein said second section can be removed from the first section to provide access to a battery carried in said first section by removal of a panel closing a storage compartment for storage of articles, and means coacting between said first and second sections provide a visible indication of the tuning of the radio.
  • FIG. 1 is a perspective view of the portable radio
  • FIG. 2 is a vertical section, on an enlarged scale, taken generally along the line 22 in FIG. 1;
  • FIG. 3 is a vertical section, taken generally along the line 33 in FIG. 2;
  • FIG. 4 is a plan section, taken generally along the line 44 in FIG. 3;
  • FIG. 5 is a plan section, taken generally along the line 55 in FIG. 3.
  • the portable radio is shown generally in FIG. 1, and comprises a generally cylindrical casing composed of a first tubular section 10, a second tubular section 11 of generally the same diameter of the first section, and a third section in the form of a ring 12 surrounding first casing section 10. Provision is made for carrying of the portable radio by means of a strap 15 connected to ears 16 and 17 formed on the upper end of the tubular section 10.
  • the first casing section 10 has a hollow interior which is closed oif at one end by a removable speaker panel 20 having a speaker 21 affixed to the underside thereof for support by the panel.
  • the first casing section 10 mounts, within the interior thereof, the primary components of the radio, with certain of these components being mounted on a removable panel 25 which is slidably guided and held in place by having the opposite edges thereof fitted into grooves 26 and 27 formed in the interior of the wall of the first casing section 10.
  • the panel mounts a circuit unit 30 and a tuning condenser 31 having a tuning shaft 32 extending downwardly therefrom.
  • a volume control and on-oif switch unit 33 is also supported by the panel 25, with a control shaft 34 extending downwardly therefrom.
  • a lower part 40 of the first casing section 10 is of a reduced diameter and has a transverse wall 41.
  • An opening 42 is provided in the wall of the lower part 40 through which a portion of a gear 43 extends for engagement with the inner periphery of the ring section 12 of the casing whereby rotation of the ring section 12 controls the on-off operation of the radio and also the volume.
  • the ring section 12 has an annular groove 45 engaging a flange 46 on the first casing section 10 to rotatably guide the ring section 12 during its movement, with the ring section 12 being held in association with the first casing section 10 by the second casing section 11 which is assembled with the first casing section 10 in a manner to be described.
  • the transverse wall 41 of the lower part 40 of the first casing section 10 is provided with an integrally-molded cylindrical battery holder 50, shown in FIG. 2, which is open at its lower end to receive a battery 51 which can be inserted from the lower end of the radio when the second casing section 11 is detached from the remainder of the radio casing.
  • the space within the second casing section 11 defines a storage compartment for articles, with a removable end closure panel 58 closing off this space.
  • the ex ternal surface of the lower part 40 of the first casing section 10 is provided with a row of indicia 60, one of which is indicated in FIG. 2, which are indivdually viewable through an aperture 61 formed'in the wall of the second casing section 11 to indicate to a user the tuning of the radio.
  • a portable radio In operation of the radio, the ring 12 is rotated to operate the on-oif switch, through rotation of the gear 43 and the shaft 34 which mounts the gear, with further rotation of the ring 12 setting the volume of the radio.
  • Rotation of the second casing section 11 then functions to operate the tuning condenser 31 to select a desired station, with this station being indicated by one of the indicia 60 viewable through the aperture 61 in the wall of the second casing section 11.
  • the end panel 58, closing oif the second "casing section 11 can be removed for access to the threaded
  • a portable radio is provided having a cylindrical shape with surfaces which can be decorated, if desired, particularly to provide styling for a female user.
  • a portable radio having a plurality of casing sections relatively rotatable about a common axis extending lengthwise of the radio, a first tubular casing section mounting a speaker across an end thereof and also mounting a tuner, a volume control and on-off switch, and a battery and with an end opposite said speaker of reduced diameter, a series of indicia disposed along said reduced end, a second tubular section of the same diameter as the first section and having a wall at one end overlapping said reduced end and with an aperture alignable with one of said indicia to indicate tuning, means rotatably interconnecting said second section with the first section and the tuner carried thereby, a third section of said casing in the form of a ring rotatably mounted on said first section, and means interconnecting said third section and the volume and on-off control to control these functions of the radio.
