Abstract

A transceiver is mounted at an end of a tubular rod, the other end of which is pivotally mounted to a helmet above the wearer'"'"''"'"'s ear. An earphone is mounted on the rod adjacent the wearer'"'"''"'"'s ear and the rod is bent so the transceiver, which contains a microphone, is in front of the wearer'"'"''"'"'s mouth. An antenna extends from the transceiver to a position above the helmet. The pivotal mount allows the rod to be positioned above the wearer'"'"''"'"'s head when the transceiver is not in use.

Claims

1. A communications transceiver apparatus adapted for mounting on a helmet type of headgear comprising a clamp mechanism adapted to be detachably attached to a bottom side edge of said helmet in a position normally overlying an individual'"'"''"'"'s ear when the helmet is worn by the individual;

tubular rod having one end pivotally attached to said clamp mechanism with the opposite end projecting downwardly and outwardly therefrom to a position substantially below and in front of said helmet adjacent an individual'"'"''"'"'s mouth;

means adjustably selecting the position of said tubular rod about said clamp mechanism;

a transceiver device mounted on said terminal end of said tubular rod in a position substantially in front of an individual'"'"''"'"'s mouth, said transceiver including a control switch projecting from a surface thereof and adapted to activate and de-activate said transceiver;

said transceiver including a channel selector knob proJecting from a surface thereof and adapted to be operated by an individual to select one of a plurality number of available channels for the transmitting and receiving of communications on the transceiver device;

an earphone mounted on said tubular rod in close proximity to said clamp mechanism and in position to overlie an adjacent individual'"'"''"'"'s ear;

electrical conducting means interconnecting said earphone and said transceiver device;

an elongated antenna rod having one end projecting outwardly of a side surface of said transceiver device, said antenna rod projecting from said transceiver device in a direction upwardly and rearwardly toward said helmet and terminating in a position spaced above said helmet;

a coil housing affixed to said terminal end of said antenna rod an in electrical connection therewith; and

a second antenna rod having one end affixed to the opposite end of said coil housing with the second antenna rod projecting outwardly therefrom in a generally horizontal direction to overlie said top of said helmet when said transceiver device is in position in front of said individual'"'"''"'"'s mouth.

2. The apparatus as set forth in claim 1 wherein said clamp mechanism comprises a first clamp member and a second clamp member, said first clamp member spaced outwardly from said second clamp member with each clamp member having a top end portion and a bottom end portion, rivet means interconnecting said first and second clamp members approximately centrally thereof and providing a general pivot axis thereabout, said clamp members adapted to receive intermediate said top end portions thereof a bottom edge portion of said helmet, a threaded shaft having one end journaled for rotation in an interior surface of said first clamp member with the shaft extending outwardly therefrom and threadedly received in a threaded opening provided in said bottom end portion of said second clamp member, rotation of said shaft in one direction about its axis effecting the outward movement of said clamp member bottom end portions relative to each other in a manner to effect pivotal movement of said rivet pin in a manner to move said top end portions inwardly relative to each other in a clamping movement, rotation of said shaft in the opposite direction about its axis effecting the inward movement of said clamp member bottom end portions relative to each other thus effecting the simultaneous pivotal movement of said clamp members about said rivet pin in a manner to move said clamp member top end portions outwardly relative to each other in an unclamping movement, and means affixed to the projecting end of said shaft adapted to be grasped between the fingers of an individual'"'"''"'"'s hand to effect the selected rotative movement of the shaft in a selected direction about its axis.

3. The apparatus as set forth in claim 1 wherein said means pivotally mounting one end of said tubular rod to said clamp mechanism comprises a bore extending through said one end of said tubular rod member, said bore being received on said shaft in a position intermediate said second clamping member and said enlarged head portion mounted on the terminal end of said shaft, compression spring interposed between said second clamp member and said adjacent surface of said tubular rod member, and a wing nut threadedly received on said shaft intermediate said terminal end portion and said opposite side surface of said tubular rod end, the rotation of said wing nut about said shaft effecting the compression of said spring as said tubular rod end is forced inwardly in the direction of said second clamp member to thus retain said rod member in a desired angular position relative to said clamp mechanism.
