This invention relates to a new and useful shock absorbing antenna mount.
An object of this invention is to provide a simple-and efiicient flexible mount for an antenna, which mount is particularly adapted for absorbing mechanical shocks and the prevention of mechanical injury.
Another object of this invention is to provide an improved telescoping antenna structure which is made up of component parts, some of which are capable of being employed as additional or series loading inductance in the-antenna.
This application is a division of my copending application, Serial'No. 485,122, filed April 30,1943, which issued as U. S. Patent 2,419,611 on April 29, 1947.
A feature of this invention is the arrangement of a mounting plate coupled together with an antenna sleeve by means of a coil spring, the antenna'member being arranged to be extended or retracted through the sleevespring and mounting plate. The antenna mount of this invention makes possible the use of a telescoping antenna, with a resilient spring mount arranged to prevent mechanical injury to the extended portion of the antenna. The antenna mount of this invention is particularly useful with portable radio apparatus, such as transmitters and receivers, wherein it is desirable to have a built-in antenna made of telescoping sections so that it may be adjusted to any desired length and when not in use collapsed into the main assembly. Antennae of this type, as known in the prior art, are usually constructed in several sections of thin wall metal tubing, which are often damaged beyond repair by merely striking some object sufliciently hard to bend a tube section.
This application is a further improvement in antennae of the type shown by a Hathaway Patent 2,161,707, dated June 6, 1939.
This invention will best be understood by referring to the accompanying drawing in which:
Fig. 1 is an elevation of the antenna mounting of this invention,
Fig. 2 is a plan view of Fig. 1,
Fig. 3 is a diagram showing the antenna member connected to form a series loading inductance, and
Fig. 4 is a sectional detail showing a modification of Fig. 1.
Referring now to Figs. 1 and 2 of the drawing, the fundamental portion of the antenna I comprises two or more pieces of thin wall metal tubes lA, IB and 1C which are arranged to telescope within each other. A base plate 2 is provided with r suitable apertures 3 for mounting'the antenna to the desired apparatus, which may'be'thatof a radioreceiving or transmitting set. There is also 'provided a lower coil support 7 which is secured by suitable meanasuch as threading or a sliding fit to the mounting plate 2. An antenna sleeve 4 is located slightly above the base plate 2 and'is secured thereto by means of an inductive helical coil spring 5 of metal, which is fastened to-support7 and sleeve4 by any suitable means "such as, for example, by welding or soldering.
With the antenna l extended, thebottom'section fits tightly into the swaged tube 6 to make good electrical connection, also so that any mechanical shock is transmitted to the coil spring which will absorb the shock and thus prevent damage tothe extended sections. When the antenna is not-in use, it may be collapsed as shown in a retracted positionas indicated by the 'dash and dot lines. The'top end of tube IA is terminated with 'a small metallic" ball 9.
As shown by Figs. 3 and 4, the coil spring 5 may be used as a series loading inductance by selecting the number of turns and the diameter of the helix to obtain the required amount of series inductance. When the antenna is used in this manner, the electrical connection is made between the antenna assembly portion above member I and the apparatus at the mounting plate 2. If it is desired to use the spring mount without the additonal series inductance, the antenna sleeve I should be made of a non-conducting material such as, for example, Bakelite or Isolantite. Other portions of the antenna are insulated to obtain the desired electrical circuit characteristics. Electrical connection is then made by a single flexible conductor 15 connected to the swaged tube 6 and the apparatus and also through the inside of the coil spring 5.
While I have indicated and described a system for carrying my invention into effect, it will be apparent to one skilled in the art that my invention is by no means limited to the particular mechanism shown and described, but that many modifications may be made without departing from the scope of my invention.
