Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is in the general field of radio transmitting and
receiving apparatus for use by police or other undercover agents,
or the like. It is in the specific field of a body transmitter and
receiver carried by a shoulder holster harness.
2. Description of the Prior Art
In the police, and similar undercover work activities, there have
been many developments in the field of radio transmitters,
receivers and transceiver units. These are generally well-known to
those skilled in the art. Such units in general incorporate items
such as "walkie-talkies", and the like.
Such units have a common limitation in size and in the combined
mechanical arrangement.
There have been some attempts to provide confidential radio
transmission by use of a single shoulder holster. This is
effective, but leaves the problem of receiving by the same agent in
an uncertain state.
Our new double shoulder holster arrangement with a receiver and
transmitter appropriately interconnected and independent from one
another represents the first known step in this direction and thus
there is no prior art to this exact invention.
SUMMARY OF THE INVENTION
Governmental and police personnel, and the like, have a great
requirement for confidential and secret transmission from the
immediate vicinity of such individuals as well as the requirement
for receipt by such individuals of varying types of information,
including that picked up and transmitted by radio from other
persons in the vicinity.
The bulk of this work has been accomplished by the use of
walkie-talkie units, which are well-known to those skilled in the
art. Such units have a common deficiency in the size required for a
proper unit, including power supply, and in the difficulty of
secret actuation of the transmitting and/or receiving
functions.
Particularly in the area of transmitting, many deviations from
walkie-talkies have been utilized because of the bulk of such units
and other disadvantages. Such deviations have included the wide use
of miniature transmitters, either affixed to the body, or otherwise
concealed in such manner that those in the vicinity of the agent,
or other person, are not normally aware of their presence. These
units are frequently continuously operating. This results in a
waste of power and sometimes the inability to transmit when
required. Such units frequently have been supplied with switches,
but the problem of conspicuousness has also been difficult in this
regard, since an agent or the like may wish to commence
transmission at an unexpected time when a conversation he desires
to transmit is taking place.
We have studied this problem and have provided a unique solution in
the form of a shoulder holster which is easy to use, is
inconspecuous and comfortable and provides the necessary wiring
attachments for both the receiver and transmitter. Likewise, we
have provided a unique switching arrangement in connection
therewith for actuation completely invisibly by use of an arm.
It is an object of this invention to provide a radio transmitter
and receiver combination for secret use carried upon the person of
the user;
Another object of this invention is to provide body worn
transmitter and receiver units which are interconnected for cut off
of the receiving unit during transmission by the transmitter;
A further object of this invention is to provide a device of the
nature mentioned in which the receiver may be activated as desired
and in which the communication may be heard confidentially;
A further object of this invention is to provide a device as
mentioned in which the transmitter may be activated by an
unnoticeable arm motion.
The foregoing and other objects and advantages of this invention
will be understood by those skilled in the art upon reading the
Description of a Preferred Embodiment which follows together with
the appended drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic perspective of a preferred embodiment of this
invention;
FIG. 2 is a front view of an individual wearing the embodiment
shown in FIG. 1;
FIG. 3 is a rear view of the same person indicated in FIG. 2;
and
FIG. 4 is a schematic drawing of the general wiring diagram
utilizing block units.
DESCRIPTION OF A PREFERRED EMBODIMENT
It will be observed that there is a right side holster arrangement
30 and a left side holster arrangement 20 joined by supporting and
connecting straps 10 and 40 respectively.
The right side arrangement 30 carries a receiver 32 in a pouch
indicated with a confidential speaker high on the shoulder as
indicated at 34. An appropriate aerial arrangement 33 is provided
through the straps to assure proper reception.
The left side arrangement includes a microphone arrangement 24 high
on the left shoulder, which arrangement is so connected to the
transmitter 22, carried in a lower pouch, so as to provide for
proper pick up of voices in the normal condition.
An appropriate aerial wire (not shown) is also provided for
appropriate transmission and such wire is similarly located to that
shown in conjunction with the receiver.
Appropriate wires 42 connect the units.
Within the pouch 32 is located the receiver 36, and within the
pouch 22 is located the transmitter 26.
The various wiring elements 27, 37, 33 and others not shown will be
recognized by those skilled in the art.
In the illustrations shown, the person wearing the device is also
shown to have handcuffs 60 and weapon 80, since such individual
will normally be an officer of the law.
The schematic diagram shown in FIG. 4 illustrates the
interconnection of the switching arrangement so that when the
receiver is being utilized the transmitter is disconnected, so that
there will not be an interference back through the receiver from
this same transmitter which would be a telltale indication to
anyone else in the vicinity. Thus it is seen that for transmission
of information the arm switch as indicated 43 will be activated and
there is no danger of receipt of information back. The switch may
be located upon the harness immediately above the transmitter
26.
In the schematic diagram, the receiver is indicated by the block
drawing, generally 36, having a battery 39, and the transmitter,
generally 26 has its battery 29. It will be noted that the wiring
between the receiver positive and negative connections is
interrupted when the switch arm 72 is moved to interconnect 76 and
71 rather than 71 and 73. In this case, there is no circuit
completed to the receiver, thus the receiver is inactive. When it
is in this condition, of course, the switch arm 75 has closed the
circuit between 74 and 77 causing a transmission circuit to be
completed.
By utilizing this switch 70, which is a double pull double throw
switch, it is clear that complete safety is insured since the
receiver will always be inactive when the transmitter is
operating.
The interconnection of these two units now firmly attached to one
another with no danger in a double shoulder harness arrangement is
a completely unique arrangement. While it is recognized that there
has been some work done in connection with individual shoulder
harness arrangements for a transmitter and individual shoulder
harness arrangement for a receiver, it is not safe to use the same,
since any failure to proper connect the two, so that one is
inoperative while the other is operative, could result in complete
disaster to the operator using the unit.
We are able to provide complete safety for the operator in this
respect by the joint arrangements set forth.
While the embodiment of this invention shown and described is fully
capable of achieving the objects and advantages desired, it is to
be understood that such embodiment has been shown for purposes of
illustration only and not for purposes of limitation.
