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 connected to a radio module through respective cables, the radio module being capable of selecting one or more of the antennas in good communication conditions, wherein a movable case is pivotally supported on a base case through a hinge mechanism, and the radio module is contained in the base case, while the plurality of antennas are disposed in the movable case, the hinge mechanism comprising a cylindrical shaft member openably and closably connecting the base case and the movable case to each other, an outer peripheral surface of the shaft member having a plurality of circumferentially extending groove portions provided at axially spaced intervals, the plurality of cables extending between the plurality of antennas and the radio module being wound around the outer peripheral surface of the shaft member while being respectively fitted in the plurality of groove portions of the shaft member.
