Abstract
An extensible antenna, particularly for automobiles, incorporates a plurality of inter-connectable elements which are separated and wound on separate reels when the antenna is retracted. The antenna elements pass from the reels through a connecting mechanism, such as a plurality of rollers, to be connected together for extension of the antenna. The antenna elements each are formed with a longitudinal groove on one surface and a longitudinal projection on another surface, and are shaped so that the projection on one element is pressed into engagement with a corresponding groove on the next adjacent element by the rollers as the antenna is extended, to form a connected antenna.
Claims9
An extensible antenna, comprising:
- a plurality of elongated antenna elements, each having at least two joining surfaces, one joining surface having a longitudinally extending groove and the other joining surface having a longitudinally extending projection;
- reel means for storing each of said antenna elements when the antenna is retracted;
- and
- an assembly mechanism engaging and withdrawing said antenna elements from said reel means and interconnecting said antenna elements to extend the antenna, said assembly mechanism including means pressing an elongated projecting on a joining surface of one of said plurality of antenna elements into a corresponding groove on a joining surface of a next adjacent antenna element whereby adjacent antenna elements are interconnected to produce a unitary extended antenna.
An extensible antenna having a retracted position and an extended position, comprising:
- a plurality of elongated antenna elements each having at least two joining surfaces and an outside surface, one joining surface having a first interlock means and the second joining surface having a second interlock means;
- reel means for each of said plurality of antenna elements, said reel means storing corresponding antenna elements when said antenna is in the retracted position;
- a plurality of roller means, each roller means engaging the outside surface of a corresponding one of said antenna elements, said roller means pressing said antenna elements together to cause the first and second interlock means of adjacent joining surfaces to engage to form a united antenna;
- and
- drive means connected to said reel means and to said roller means for extending and retracting said antenna.
