Abstract
PURPOSE:To realize a simple and light-weight structure of the antenna by securing rotations of the antenna via the centrifugal force caused by the rotary motion of the shaft. CONSTITUTION:With rotation of rod 12, folded ribs 13 expand and stops at the position where a balance is obtained between the rib and the tension of wire 14 if the rib and each hinge are connected previously via wire 14. Accordingly, various kinds of axis symmetric faces are formed around rod 12 by adjusting the length of the wire. Furthermore, if the locking mechanism using, for example, a projection is provided to the hinge, the symmetric formation can be kept after the ribs are once expanded even through the rotation is stoped. In such structure, an antenna is formed by attaching expnanding mesh 15 to the wire. Thus an expansion antenna can be obtained with a simple and light-weight structure.
