Abstract
In an antenna device of the present invention, an upper cabinet 2 is pivotally supported on a lower cabinet 4 through a hinge mechanism 3, the lower cabinet 4 containing a radio module 41, the upper cabinet 2 having a plurality of antennas 21 disposed therein. The hinge mechanism 3 includes a cylindrical shaft member 31 openably and closably connecting the two cabinets 2, 4 to each other, an outer peripheral surface of the shaft member 31 having a plurality of groove portions 32 formed at axially spaced intervals. A plurality of cables 22 are wound around the outer peripheral surface of the shaft member 31 while being respectively fitted in the plurality of groove portions 32.
Claims8
A collapsible antenna device comprising a plurality of antennas 21 connected to a radio module 41 through respective cables, the radio module 41 being capable of selecting one or more of the antennas 21 in good communication conditions, wherein a movable case is pivotally supported on a base case through a hinge mechanism 3, and the radio module 41 is contained in the base case, while the plurality of antennas 21 are disposed in the movable case, the hinge mechanism 3 comprising a cylindrical shaft member 31 openably and closably connecting the base case and the movable case to each other, an outer peripheral surface of the shaft member 31 having a plurality of circumferentially extending groove portions 32 provided at axially spaced intervals, the plurality of cables extending between the plurality of antennas 21 and the radio module 41 being wound around the outer peripheral surface of the shaft member 31 while being respectively fitted in the plurality of groove portions 32 of the shaft member 31.
A collapsible antenna device comprising a plurality of antennas 21 connected to a radio module 41 through respective cables, the radio module 41 being capable of selecting one or more of the antennas 21 in good communication conditions, wherein a movable case is pivotally supported on a base case through a hinge mechanism 3, and the radio module 41 is contained in the base case, while the plurality of antennas 21 are disposed in the movable case, the hinge mechanism 3 comprising a cylindrical shaft member 24 openably and closably connecting the base case and the movable case to each other, the base case having disposed thereon a guide surface 40 opposed to an outer peripheral surface of the shaft member 24, the plurality of cables extending between the plurality of antennas 21 and the radio module 41 being held at mutually spaced intervals between the outer peripheral surface of the shaft member 24 and the guide surface 40.
